TY - JOUR T1 - An Arctic and Subarctic ostracode database: biogeographic and paleoceanographic applications AN - 1859497969; PQ0003971745 AB - A new Arctic Ostracode Database-2015 (AOD-2015) provides census data for 96 species of benthic marine Ostracoda from 1340 modern surface sediments from the Arctic Ocean and subarctic seas. Ostracoda is a meiofaunal, Crustacea group that secretes a bivalved calcareous (CaCO sub(3)) shell commonly preserved in sediments. Arctic and subarctic ostracode species have ecological limits controlled by temperature, salinity, oxygen, sea ice, food, and other habitat-related factors. Unique species ecology, shell chemistry (Mg/Ca ratios, stable isotopes), and limited stratigraphic ranges make them a useful tool for paleoceanographic reconstructions and biostratigraphy. The database, described here, will facilitate the investigation of modern ostracode biogeography, regional community structure, and ecology. These data, when compared to downcore faunal data from sediment cores, will provide a better understanding of how the Arctic has been affected by climatic and oceanographic change during the Quaternary. Images of all species and biogeographic distribution maps for selected species are presented, with brief discussion of representative species' biogeographic and ecological significance. Publication of AOD-2015 is open-sourced and will be available online at several public websites with latitude, longitude, water depth, and bottom water temperature for most samples. It includes material from Arctic abyssal plains and submarine ridges, continental slopes, and shelves of the Kara, Laptev, East Siberian, Chukchi, Beaufort Seas, and several subarctic regions.

The decadal-scale coastal change is controlled by processes that occur on short time scales (such as storms) and long-term processes (such as prevailing waves). The ability to predict decadal-scale shoreline change is not well established and the fundamental physical processes controlling this change are not well understood. Here we investigate the processes that create large-scale long-term shoreline change along the Outer Banks of North Carolina, an uninterrupted 60km stretch of coastline, using both observations and a numerical modeling approach. Shoreline positions for a 24-yr period were derived from aerial photographs of the Outer Banks. Analysis of the shoreline position data showed that, although variable, the shoreline eroded an average of 1.5m/yr throughout this period. The modeling approach uses a three-dimensional hydrodynamics-based numerical model coupled to a spectral wave model and simulates the full 24-yr time period on a spatial grid running on a short (second scale) time-step to compute the sediment transport patterns. The observations and the model results show similar magnitudes (O(105 m3/yr)) and patterns of alongshore sediment fluxes. Both the observed and the modeled alongshore sediment transport rates have more rapid changes at the north of our section due to continuously curving coastline, and possible effects of alongshore variations in shelf bathymetry. The southern section with a relatively uniform orientation, on the other hand, has less rapid transport rate changes. Alongshore gradients of the modeled sediment fluxes are translated into shoreline change rates that have agreement in some locations but vary in others. Differences between observations and model results are potentially influenced by geologic framework processes not included in the model. Both the observations and the model results show higher rates of erosion (-1m/yr) averaged over the northern half of the section as compared to the southern half where the observed and modeled averaged net shoreline changes are smaller (<0.1m/yr). The model indicates accretion in some shallow embayments, whereas observations indicate erosion in these locations. Further analysis identifies that the magnitude of net alongshore sediment transport is strongly dominated by events associated with high wave energy. However, both big- and small- wave events cause shoreline change of the same order of magnitude because it is the gradients in transport, not the magnitude, that are controlling shoreline change. Results also indicate that alongshore momentum is not a simple balance between wave breaking and bottom stress, but also includes processes of horizontal vortex force, horizontal advection and pressure gradient that contribute to long-term alongshore sediment transport. As a comparison to a more simple approach, an empirical formulation for alongshore sediment transport is used. The empirical estimates capture the effect of the breaking term in the hydrodynamics-based model, however, other processes that are accounted for in the hydrodynamics-based model improve the agreement with the observed alongshore sediment transport.

AN - 1861585041; 28108667 AB - We investigated the effects of the androgenic growth promoter 17ß-trenbolone (17βTB) on adult Japanese quail (Coturnix japonica) exposed across three generations. The F0 generation was exposed after sexual maturity to 0, 1, 5, 10, 20, and 40 ppm through feed. The F1 generation was exposed in ovo by maternal transfer and through feed at the same doses as their parents. The F2 generation was exposed in ovo only. Levels of plasma sex steroids, gonadal Cytochrome P450 aromatase (CYP19A1) mRNA and select brain neuroendocrine peptide mRNAs were measured. In males, testosterone levels did not differ in any generation from those in controls. Estradiol was significantly elevated in 17βTB treated F0 and F1 males. In F0 and F1 females, testosterone was suppressed by 17βTB, whereas estradiol was significantly higher at 40 ppm in F0 and at 10 ppm in F1 females. CYP19A1expression in F1 males and females increased suggesting a compensatory response to the androgenic effects of 17βTB. Few significant effects were observed in the F2 birds indicating that in ovo exposure had limited effects on the monitored endpoints. Overall, our results confirmed endocrine disrupting effects of dietary 17βTB in Japanese quail but the response was dependent on sex, developmental stage at initiation of exposure, and dose.

However, relative to open coasts, there has been little quantification of storm-induced bathymetric change in back-barrier estuaries. Vessel-based and airborne bathymetric mapping can cover large areas quickly, but change detection is difficult because measurement errors can be larger than the actual changes over the storm timescale. We quantified storm-induced bathymetric changes at several locations in Chincoteague Bay, Maryland/Virginia, over the August 2014 to July 2015 period using fixed, downward-looking altimeters and numerical modeling. At sand-dominated shoal sites, measurements showed storm-induced changes on the order of 5 cm, with variability related to stress magnitude and wind direction. Numerical modeling indicates that the predominantly northeasterly wind direction in the fall and winter promotes southwest-directed sediment transport, causing erosion of the northern face of sandy shoals; southwesterly winds in the spring and summer lead to the opposite trend. Our results suggest that storm-induced estuarine bathymetric change magnitudes are often smaller than those detectable with methods such as LiDAR. More precise fixed-sensor methods have the ability to elucidate the geomorphic processes responsible for modulating estuarine bathymetry on the event and seasonal timescale, but are limited spatially. Numerical modeling enables interpretation of broad-scale geomorphic processes and can be used to infer the long-term trajectory of estuarine bathymetric change due to episodic events, when informed by fixed-sensor methods.

Landscape patterning in consumer population dynamics may be largely the result of interactions between consumers and their predators, or driven by spatial variation in basal resources. Empirical testing of these alternatives has been limited by the lack of suitable data. In this study, we analyzed an extensive network of spatially replicated time series to characterize the local and regional processes affecting spatio-temporal dynamics of a tree-killing bark beetle (Dendroctonus frontalis or SPB) and its key predator (Thanasimus dubius) across the southeastern United States. We first used a mechanistic model to evaluate factors affecting the stability of 95 predator-prey time series and then conducted spatial analyses to evaluate scale dependence in the factors affecting the geographical patterning of this system. Across the region, population fluctuations of both species were correlated in space beyond 400 km but there was notable spatial variation in the deterministic and stochastic processes influencing forest-scale (local) fluctuations. Time series analyses indicated that local dynamics of SPB and T. dubius are not cyclical. Instead, the abundance of T. dubius responded almost instantaneously to changes in SPB abundance. Spatial variation in long-term forest-scale abundance of both species was linked most strongly to the abundance of pine habitat indicating a stronger role for resource availability in SPB population dynamics than top-down effects. Our results are consistent with other studies indicating that animal populations tend to be synchronized in space via spatially correlated processes such as weather; yet local dynamics tend to be linked to smaller-scale host patterns. Our study provides a rare empirical assessment of how local processes scale up to produce landscape patterns that influence forest ecology and forest management.

Snowy egret post-fledging dispersal, timing of migration and survival, 2002-2004. AN - 1835532387; 27771593 AB - This telemetry study is an extension of our 1997-2006 research on historical mercury contamination on snowy egrets (Egretta thula) up to ~ 20 days of age. Findings from initial studies at the mercury-contaminated Carson River colony at Lahontan Reservoir (LR) and a similar-sized reference (REF) colony on the Humboldt River included mercury-related physiological, biochemical, histopathological and reproductive effects up to ~20 days of age; with poor water years (2000-04), i.e., reduced prey availability, exacerbating effects. Herein, we compare timing of dispersal and migration at LR vs. REF, but the primary question now addressed is "whether survival of young mercury-exposed snowy egrets from LR would be further compromised beyond ~20 days of age? " Based upon telemetry signals until 90-110 days of age (including dead bird counts and survival rate estimates), we conclude that mercury did not further compromise survival. Dead bird counts and survival rate estimates included time in the colony when fed by adults, plus the critical period when young dispersed from the colony to forage independently. The extended drought during this 3-year study was most critical in 2002 when production of ~20d old egrets at LR was only 0.24 young/nest. In 2002, survival rates were low at both colonies and we documented the highest counts of dead egrets for both colonies. We suggest the losses in 2002 beyond 20 days of age were more a function of prey availability influenced by drought than exposure to mercury, especially at LR, because higher mercury concentrations, higher survival rates and fewer dead birds were documented at LR in 2003 when water conditions improved. Furthermore, total mercury (THg) in blood in 2003 was more than double 2002 (geometric mean, 3.39 vs 1.47µg/g wet weight (ww). This higher THg exposure at LR in 2003 was associated with a redistribution of parent and post-dispersal feeding activities upstream (where there was higher mercury from historic mining) related to slightly improved water levels. When comparing the 3-year telemetry findings based upon ~20d old young at LR (blood THg, geo. means 1.47, 3.39 and 1.89µg/g ww), we found no evidence that age at dispersal, Julian date at dispersal, timing of migration, or pre-migration survival (~20 to ~100 days post-hatch) were adversely affected by elevated mercury.

Seventy-two well-recorded local earthquakes are used to calculate spectral amplitude ratios relative to a reference site. A well-defined fundamental resonance peak is observed with individual station amplitudes following the theoretically predicted progression of larger amplitudes in the upslope direction. Favored directions of vibration are also seen that are related to the trapping of shear waves within the primary ridge dimensions. Spectral peaks above the fundamental one are also related to topographic effects but follow a more complex pattern. Theoretical predictions using a 3D velocity model and accurate topography reproduce many of the general frequency and time-domain features of the data. Shifts in spectral frequencies and amplitude differences, however, are related to deficiencies of the model and point out the importance of contributing factors, including the shear-wave velocity under the topographic feature, near-surface velocity gradients, and source parameters.

This article describes the third set of designs and tests in our development program. The details of our results for most of these are in the electronic supplement to this article, whereas here we concentrate on three of the most promising and representative design combinations.Most of our results pertain to sensors with water or silicon oil as the proof mass, though we also tested a torsion-bar design with a solid proof mass. We find that most mass-transducer combinations lead to output proportional to rotational acceleration, with varying degrees of fidelity. Most combinations we tested can be dismissed from further development for reasons of performance or inconvenience during analysis of acceleration response (compare with electronic supplement). In this article, we describe three of the more promising combinations, one each for the three types of response functions we measured. Of these three, one mass-transducer combination in particular (a hinged sensing element and capacitive transduction) has output voltage closely proportional to rotational displacement (angle) over a wide frequency range; such displacement proportionality obviates two of the integration steps normally required to solve for continuum single-point motions or correct for tilt-induced errors in horizontal translational sensors. Thus, although we illustrate two other designs of some promise, we propose a new design that follows this displacement-proportional path while increasing the device's sensitivity to on-axis rotations, improving its manufacturing ease and lowering its sensitivity to translational motions.Online Material: Results and related material for mass-transceiver combinations, drawings and photographs of liquid proof masses, amplitude and phase transfer functions, clip and linearity tests, and noise plots.

Recently, uranium-series (U-series) disequilibria have shown great potential for determining rind formation rates and quantifying factors controlling weathering advance rates in weathering rinds. To further investigate whether the U-series isotope technique can document differences in long term weathering rates as a function of precipitation, we conducted a new weathering rind study on tropical volcanic Basse-Terre Island in the Lesser Antilles Archipelago. In this study, for the first time we characterized weathering reactions and quantified weathering advance rates in multiple weathering rinds across a steep precipitation gradient. Electron microprobe (EMP) point measurements, bulk major element contents, and U-series isotope compositions were determined in two weathering clasts from the Deshaies watershed with mean annual precipitation (MAP) = 1800 mm and temperature (MAT) = 23 degrees C. On these clasts, five core-rind transects were measured for locations with different curvature (high, medium, and low) of the rind-core boundary. Results reveal that during rind formation the fraction of elemental loss decreases in the order: Ca nearly equal Na > K nearly equal Mg > Si nearly equal Al > Zr nearly equal Ti nearly equal Fe. Such observations are consistent with the sequence of reactions after the initiation of weathering: specifically, glass matrix and primary minerals (plagioclase, pyroxene) weather to produce Fe oxyhydroxides, gibbsite and minor kaolinite.Uranium shows addition profiles in the rind due to the infiltration of U-containing soil pore water into the rind as dissolved U phases. U is then incorporated into the rind as Fe-Al oxides precipitate. Such processes lead to significant U-series isotope disequilibria in the rinds. This is the first time that multiple weathering clasts from the same watershed were analyzed for U-series isotope disequlibrian and show consistent results. The U-series disequilibria allowed for the determination of rind formation ages and weathering advance rates with a U-series mass balance model. The weathering advance rates generally decreased with decreasing curvature: approximately 0.17 + or - 0.10 mm/kyr for high curvature, approximately 0.12 + or - 0.05 mm/kyr for medium curvature, and approximately 0.11 + or - 0.04, 0.08 + or - 0.03, 0.06 + or - 0.03 mm/kyr for low curvature locations. The observed positive correlation between the curvature and the weathering rates is well supported by predictions of weathering models, i.e., that the curvature of the rind-core boundary controls the porosity creation and weathering advance rates at the clast scale.At the watershed scale, the new weathering advance rates derived on the low curvature transects for the relatively dry Deshaies watershed (average rate of 0.08 mm/kyr; MAP = 1800 mm and MAT = 23 degrees C) are approximately 60% slower than the rind formation rates previously determined in the much wetter Bras David watershed ( approximately 0.18 mm/kyr, low curvature transect; MAP = 3400 mm and MAT = 23 degrees C) also on Basse-Terre Island. Thus, a doubling of MAP roughly correlates with a doubling of weathering advance rate. The new rind study highlights the effect of precipitation on weathering rates over a time scale of approximately 100 kyr. Weathering rinds are thus a suitable system for investigating long-term chemical weathering across environmental gradients, complementing short-term riverine solute fluxes.

Recently, estimators have been developed to estimate occupancy probabilities when false-positive detections occur during presence-absence surveys. Some of these estimators combine different types of survey data to improve estimates of occupancy. With these estimators, there is a trade-off between the number of sample units surveyed, and the number and type of surveys at each sample unit. Guidance on efficient design of studies when false positives occur is unavailable. 2. For a range of scenarios, I identified survey designs that minimized the mean square error of the estimate of occupancy. I considered an approach that uses one survey method and two observation states and an approach that uses two survey methods. For each approach, I used numerical methods to identify optimal survey designs when model assumptions were met and parameter values were correctly anticipated, when parameter values were not correctly anticipated and when the assumption of no unmodelled detection heterogeneity was violated. 3. Under the approach with two observation states, false-positive detections increased the number of recommended surveys, relative to standard occupancy models. If parameter values could not be anticipated, pessimism about detection probabilities avoided poor designs. Detection heterogeneity could require more or fewer repeat surveys, depending on parameter values. If model assumptions were met, the approach with two survey methods was inefficient. However, with poor anticipation of parameter values, with detection heterogeneity or with removal sampling schemes, combining two survey methods could improve estimates of occupancy. 4. Ignoring false positives can yield biased parameter estimates, yet false positives greatly complicate the design of occupancy studies. Specific guidance for major types of false-positive occupancy models, and for two assumption violations common in field data, can conserve survey resources. This guidance can be used to design efficient monitoring programmes and studies of species occurrence, species distribution or habitat selection, when false positives occur during surveys.

The predictive value of the MTT to evaluate the pattern and timing of groundwater response to hydraulic stress (i.e., vulnerability) is examined by a statistical analysis of MTT, historical spring discharge records, and the Palmer Hydrological Drought Index. MTTs of the springs range from 10 to 15,000 years and 90 % of the cumulative discharge-weighted travel-time distribution falls within the range of 2-10,000 years. Historical variability in discharge was assessed as the ratio of 10-90 % flow-exceedance (R sub(10/90%)) and ranged from 2.8 to 1.1 for select springs with available discharge data. The lag-time (i.e., delay in discharge response to drought conditions) was determined by cross-correlation analysis and ranged from 0.5 to 6 years for the same select springs. Springs with shorter MTTs (<80 years) statistically correlate with larger discharge variations and faster responses to drought, indicating MTT can be used for estimating the relative magnitude and timing of groundwater response. Results indicate that groundwater discharge to streams in the UCRB will likely respond on the order of years to climate variation and increasing groundwater withdrawals.Original Abstract: Les traceurs environnementaux (gaz nobles, tritium, gaz industriels, isotopes stables, et carbone radioactif) et l'hydrogeologie ont ete interpretes pour determiner la repartition du temps de transit des eaux souterraines et calculer le temps de transit moyen (TTM) a l'aide d'une modelisation globale a parametres pour 19 grandes sources reparties sur l'ensemble du bassin versant du Colorado superieur (UCRB), Etats-Unis d'Amerique. La valeur predictive du TTM pour evaluer le schema et le temps de reponse des eaux souterraines au stress hydraulique ( a savoir, la vulnerabilite) est examinee a l'aide d'une analyse statistique des TTM, des debits historiques enregistres des sources, et de l'indice de secheresse hydrologique de Palmer. Les TTM des sources est compris entre 10 a 15,000 ans et 90 % de la distribution du debit cumule pondere par le temps de transit se situent dans la fourchette comprise entre 2 a 10,000 ans. La variabilite historique du debit a ete evaluee comme etant le rapport de 10-90 % du flux excedentaire (R sub(10/90%)) et variait de 2.8 a 1 .1 pour certaines sources a partir de donnees de debit disponibles. Le temps de latence (a savoir, le retard dans la reponse du debit par rapport aux conditions de secheresse) a ete determine par une analyse de correlation croisee et variait de 0.5-6 ans pour la meme selection de sources. Les sources avec des TTM plus courtes (<80 ans) sont correlees statistiquement avec de plus grandes variations de debit et des reponses plus rapides a la secheresse, indiquant que le TTM peut etre utilise pour estimer l'importance relative et le temps de reponse des eaux souterraines. Les resultats indiquent que la decharge des eaux souterraines vers les cours d'eau dans le UCRB repondra probablement a la variation climatique et a l'augmentation des prelevements d'eaux souterraines dans un laps de temps correspondant a l'ordre de grandeur des annees.

The data were recorded on three arrays deployed across north and south of the 2014 surface rupture. The observed FZGWs indicate that the West Napa fault zone (WNFZ) and the Franklin fault (FF) are continuous in the subsurface for at least 75 km. Previously published potential-field data indicate that the WNFZ extends northward to the Maacama fault (MF), and previous geologic mapping indicates that the FF extends southward to the Calaveras fault (CF); this suggests a total length of at least 110 km for the WNFZ-FF. Because the WNFZ-FF appears contiguous with the MF and CF, these faults apparently form a continuous Calaveras-Franklin-WNFZ-Maacama (CFWM) fault that is second only in length ( similar to 300 km) to the San Andreas fault in the San Francisco Bay area. The long distances over which we observe FZGWs, coupled with their high amplitudes (2-10 times the S waves) suggest that strong shaking from large earthquakes on any part of the CFWM fault may cause far-field amplified fault-zone shaking. We interpret guided waves and seismicity cross sections to indicate multiple upper crustal splays of the WNFZ-FF, including a northward extension of the Southhampton fault, which may cause strong shaking in the Napa Valley and the Vallejo area. Based on travel times from each earthquake to each recording array, we estimate average P-, S-, and guided-wave velocities within the WNFZ-FF (4.8-5.7, 2.2-3.2, and 1.1-2.8 km/s, respectively), with FZGW velocities ranging from 58% to 93% of the average S-wave velocities.

However, this result has only been shown for the Pearl-Verhulst growth function on two patches and for a single-parameter growth function in continuous space. Here, we provide a general criterion for total population size to exceed total carrying capacity for three commonly used population growth rates for both heterogeneous continuous and multi-patch heterogeneous landscapes with high population diffusion. We show that a sufficient condition for this situation is that there is a convex positive relationship between the maximum growth rate and the parameter that, by itself or together with the maximum growth rate, determines the carrying capacity, as both vary across a spatial region. This relationship occurs in some biological populations, though not in others, so the result has ecological implications.

(Seism Res Lett 87:957-962, 2015) to analyse the distribution of ground motions at near-field and regional distances. We show that the data are consistent with the instrumental peak ground acceleration (PGA) versus macroseismic intensity relationship developed by Worden et al. (Bull Seism Soc Am 102:204-221, 2012), and use this relationship to estimate peak ground acceleration from intensities (PGA sub(EMS)). For nearest-fault distances (R sub(RUP) 200 km), instrumental PGA values are consistent with this GMPE, while PGA sub(EMS) is systematically higher. We suggest the latter reflects a duration effect whereby effects of weak shaking are enhanced by long-duration and/or long-period ground motions from a large event at regional distances. We use PGA sub(EMS) values within 200 km to investigate the variability of high-frequency ground motions using the Atkinson and Boore (Bull Seism Soc Am 93:1703-1729, 2003) GMPE as a baseline. Across the near-field region, PGA sub(EMS) is higher by a factor of 2.0-2.5 towards the northern, down-dip edge of the rupture compared to the near-field region nearer to the southern, up-dip edge of the rupture. Inferred deamplification in the deepest part of the Kathmandu valley supports the conclusion that former lake-bed sediments experienced a pervasive nonlinear response during the mainshock (Dixit et al. in Seismol Res Lett 86(6):1533-1539, 2015; Rajaure et al. in Tectonophysics, 2016. Ground motions were significantly amplified in the southern Gangetic basin, but were relatively low in the northern basin. The overall distribution of ground motions and damage during the Gorkha earthquake thus reflects a combination of complex source, path, and site effects. We also present a macroseismic intensity data set and analysis of ground motions for the M sub(W)7.3 Dolakha aftershock on 12 May 2015, which we compare to the Gorkha mainshock and conclude was likely a high stress-drop event.

We assessed the resilience of wetlands to sea-level rise along a transitional gradient from tidal freshwater forested wetland (TFFW) to marsh by measuring processes controlling wetland elevation. We found that, over 5 years of measurement, TFFWs were resilient, although some marginally, and oligohaline marshes exhibited robust resilience to sea-level rise. We identified fundamental differences in how resilience is maintained across wetland community types, which have important implications for management activities that aim to restore or conserve resilient systems. We showed that the relative importance of surface and subsurface processes in controlling wetland surface elevation change differed between TFFWs and oligohaline marshes. The marshes had significantly higher rates of surface accretion than the TFFWs, and in the marshes, surface accretion was the primary contributor to elevation change. In contrast, elevation change in TFFWs was more heavily influenced by subsurface processes, such as root zone expansion or compaction, which played an important role in determining resilience of TFFWs to rising sea level. When root zone contributions were removed statistically from comparisons between relative sea-level rise and surface elevation change, sites that previously had elevation rate deficits showed a surplus. Therefore, assessments of wetland resilience that do not include subsurface processes will likely misjudge vulnerability to sea-level rise.

New multibeam bathymetry coverage reveals that mass wasting is pervasive along the Yucatan Shelf edge with several large composite landslides possibly removing as much as 70 km super(3) of the Cenozoic sedimentary section in a single event. Using GIS-based analysis, the dimensions of six landslides from the central and northern sections of the Yucatan Shelf/Campeche Escarpment were determined and used as input for preliminary tsunami generation and propagation models. Tsunami modeling is performed to compare the propagation characteristics and distribution of maximum amplitudes throughout the GOM among the different landslide scenarios. Various factors such as landslide geometry, location along the Yucatan Shelf/Campeche Escarpment, and refraction during propagation result in significant variations in the affected part of the Mexican and US Gulf Coasts. In all cases, however, tsunami amplitudes are greatest along the northern Yucatan Peninsula.

Analysis of prawn passage abundance at three Snake River dams showed that populations are growing at exponential rates, especially at Little Goose Dam where over 464,000 prawns were collected in 2015. Monthly beam trawling during 2011-2013 provided information on prawn abundance and distribution in Lower Granite and Little Goose Reservoirs. Zero-inflated regression predicted that the probability of prawn presence increased with decreasing water velocity and increasing depth. Negative binomial models predicted higher catch rates of prawns in deeper water and in closer proximity to dams. Temporally, prawn densities decreased slightly in the summer, likely due to the mortality of older individuals, and then increased in autumn and winter with the emergence and recruitment of young of the year. Seasonal length frequencies showed that distinct juvenile and adult size classes exist throughout the year, suggesting prawns live from 1 to 2 years and may be able to reproduce multiple times during their life. Most juvenile prawns become reproductive adults in 1 year, and peak reproduction occurs from late July through October. Mean fecundity (189 eggs) and reproductive output (11.9 %) are similar to that in their native range. The current use of deep habitats by prawns likely makes them unavailable to most predators in the reservoirs. The distribution and role of Siberian prawns in the lower Snake River food web will probably continue to change as the population grows and warrants continued monitoring and investigation.

Springtime warming and aeolian dust deposition accelerate snowmelt, increasing the risk of water shortages during late summer, when demand is greatest. While climate networks provide data that can be used to evaluate the effect of warming on snowpack resources, there are no established regional networks for monitoring aeolian dust deposition to snow. In this study, we test the hypothesis that chemistry of snow, wet deposition, and aerosols can be used as a surrogate for dust deposition to snow. We then analyze spatial patterns and temporal trends in inferred springtime dust deposition to snow across the Rocky Mountains, USA, for 1993-2014. Geochemical evidence, including strong correlations (r2 greater than or equal to 0.94) between Ca2+, alkalinity, and dust concentrations in snow deposited during dust events, indicate that carbonate minerals in dust impart a strong chemical signature that can be used to track dust deposition to snow. Spatial patterns in chemistry of snow, wet deposition, and aerosols indicate that dust deposition increases from north to south in the Rocky Mountains, and temporal trends indicate that winter/spring dust deposition increased by 81% in the southern Rockies during 1993-2014. Using a multivariate modeling approach, we determined that increases in dust deposition and decreases in springtime snowfall combined to accelerate snowmelt timing in the southern Rockies by approximately 7-18 days between 1993 and 2014. Previous studies have shown that aeolian dust emissions may have doubled globally during the 20th century, possibly due to drought and land-use change. Climate projections for increased aridity in the southwestern U.S., northern Africa, and other mid-latitude regions of the northern Hemisphere suggest that aeolian dust emissions may continue to increase, compounding the risk that climate warming poses to snowpack water resources in arid/semi-arid regions of the world.

Tsunami amplitude distributions at tide gauge stations follow a similar functional form, well described by a tapered Pareto distribution that is parameterized by a power-law exponent and a corner amplitude. Distribution parameters are first established for eight tide gauge stations in the Pacific, using maximum likelihood estimation. A procedure is then developed to reconstruct the tsunami amplitude distribution that consists of four steps: (1) define the distribution of seismic moment at subduction zones; (2) establish a source-station scaling relation from regression analysis; (3) transform the seismic moment distribution to a tsunami amplitude distribution for each subduction zone; and (4) mix the transformed distribution for all subduction zones to an aggregate tsunami amplitude distribution specific to the tide gauge station. The tsunami amplitude distribution is adequately reconstructed for four tide gauge stations using globally constant seismic moment distribution parameters established in previous studies. In comparisons to empirical tsunami amplitude distributions from maximum likelihood estimation, the reconstructed distributions consistently exhibit higher corner amplitude values, implying that in most cases, the empirical catalogs are too short to include the largest amplitudes. Because the reconstructed distribution is based on a catalog of earthquakes that is much larger than the tsunami catalog, it is less susceptible to the effects of record-breaking events and more indicative of the actual distribution of tsunami amplitudes.

AN - 1844605633; 27608857 AB - Notoedric mange, caused by obligately parasitic sarcoptiform Notoedres mites, is associated with potentially fatal dermatitis with secondary systemic disease in small mammals, felids and procyonids among others, as well as an occasional zoonosis. We describe clinical spectra in non-chiropteran hosts, review risk factors and summarize ecological and epidemiological studies. The genus is disproportionately represented on rodents. Disease in felids and procyonids ranges from very mild to death. Knowledge of the geographical distribution of the mites is highly inadequate, with focal hot spots known for Notoedres cati in domestic cats and bobcats. Predisposing genetic and immunological factors are not known, except that co-infection with other parasites and anticoagulant rodenticide toxicoses may contribute to severe disease. Treatment of individual animals is typically successful with macrocytic lactones such as selamectin, but herd or wildlife population treatment has not been undertaken. Transmission requires close contact and typically is within a host species. Notoedric mange can kill half all individuals in a population and regulate host population below non-diseased density for decades, consistent with frequency-dependent transmission or spillover from other hosts. Epidemics are increasingly identified in various hosts, suggesting global change in suitable environmental conditions or increased reporting bias.

AN - 1841131735; 27848110 AB - Agricultural practices pose threats to biotic diversity in freshwater systems with increasing use of glyphosate-based herbicides for weed control and animal waste for soil amendment becoming common in many regions. Over the past two decades, these particular agricultural trends have corresponded with marked declines in populations of fish and mussel species in the Upper Conasauga River watershed in Georgia/Tennessee, USA. To investigate the potential role of agriculture in the population declines, surface waters and sediments throughout the basin were tested for toxicity and analyzed for glyphosate, metals, nutrients, and steroid hormones. Assessments of chronic toxicity with Ceriodaphnia dubia and Hyalella azteca indicated that few water or sediment samples were harmful and metal concentrations were generally below impairment levels. Glyphosate was not observed in surface waters, although its primary degradation product, aminomethyl phosphonic acid (AMPA), was detected in 77% of the samples (mean = 509 μg/L, n = 99) and one or both compounds were measured in most sediment samples. Waterborne AMPA concentrations supported an inference that surfactants associated with glyphosate may be present at levels sufficient to affect early life stages of mussels. Nutrient enrichment of surface waters was widespread with nitrate (mean = 0.7 mg NO3-N/L, n = 179) and phosphorus (mean = 275 μg/L, n = 179) exceeding levels associated with eutrophication. Hormone concentrations in sediments were often above those shown to cause endocrine disruption in fish and appear to reflect the widespread application of poultry litter and manure. Observed species declines may be at least partially due to hormones, although excess nutrients and herbicide surfactants may also be implicated.

Lake charr were sampled using graded-mesh gill nets set in three depth strata. Of 236 lake charr captured, 122 were a fat morph and 114 were a lean morph. Males and females did not differ from each other in any attributes for either fat or lean morphs. The fat morph averaged 15 mm longer, 481 g heavier, and 4.7 years older than the lean morph. The fat morph averaged 26% heavier and 48% more buoyant at length than the lean morph. Survival of the fat morph was 1.7% higher than that of the lean morph. The fat morph grew at a slower annual rate to a shorter asymptotic length than the lean morph. Fat and lean morphs matured at similar lengths and ages. We concluded that the connection between resource polymorphism and life histories in lean versus fat lake charr suggests that morph-specific restoration objectives may be needed in lakes where lake charr diversity is considered to be a restoration goal.

We developed a simulation model to determine the fishing mortality rate on lake trout that would enable bull trout recovery. Model simulations indicated that suppression of adult lake trout by 75% from current abundance would reduce predation on bull trout by 90%. Current removals of lake trout through incentivized fishing contests has not been sufficient to suppress lake trout abundance estimated by mark-recapture or indexed by stratified-random gill netting. In contrast, size structure, body condition, mortality, and maturity are changing consistent with a density-dependent reduction in lake trout abundance. Population modeling indicated total fishing effort would need to increase 3-fold to reduce adult lake trout population density by 75%. We conclude that increased fishing effort would suppress lake trout population density and predation on juvenile bull trout, and thereby enable higher abundance of adult bull trout in Flathead Lake and its tributaries.

However, each program faces the unifying challenge of assessing conditions and quantifying reasonable expectations for measured indicators. A common approach for setting resource expectations is to define reference conditions that represent areas of least human disturbance or most natural state of a resource characterized by the range of natural variability across a region of interest. Identification of reference sites often relies heavily on professional judgment, resulting in varying and unrepeatable methods. Standardized methods for data collection, site characterization, and reference site selection facilitate greater cooperation among assessment programs and development of assessment tools that are readily shareable and comparable. We illustrate an example that can serve the broader global monitoring community on how to create a consistent and transparent reference network for multiple stream resource agencies. We provide a case study that offers a simple example of how reference sites can be used, at the landscape level, to link upslope management practices to a specific in-channel response. We found management practices, particularly areas with high road densities, have more fine sediments than areas with fewer roads. While this example uses data from only one of the partner agencies, if data were collected in a similar manner they can be combined and create a larger, more robust dataset. We hope that this starts a dialog regarding more standardized ways through inter-agency collaborations to evaluate data. Creating more consistency in physical and biological field protocols will increase the ability to share data.

We describe a simple automated image processing routine that analyzes continuously-acquired thermal images of the lava lake and measures lava level. The method uses three image segmentation approaches, based on edge detection, short-term change analysis, and composite temperature thresholding, to identify and track the lake margin in the images. These relative measurements from the images are periodically calibrated with laser rangefinder measurements to produce real-time estimates of lake elevation. Continuous, automated tracking of the lava level has been an important tool used by the U.S. Geological Survey's Hawaiian Volcano Observatory since 2012 in real-time operational monitoring of the volcano and its hazard potential.

We studied three forested tributaries to quantify the potential climate-driven change in hydrologic budget for two 25-year time periods centered on 2030 and 2060, focusing on sensitivity to the method of estimating potential evapotranspiration (PET) change. Hydrology was simulated using the Water Availability Tool for Environmental Resources (Williamson et al. 2015). Climate-change scenarios for four Coupled Model Intercomparison Project Phase 5 (CMIP5) global climate models (GCMs) and two Representative Concentration Pathways (RCPs) were used to derive monthly change factors for temperature (T), precipitation (PPT), and PET according to the energy-based method of Priestley and Taylor (1972). Hydrologic simulations indicate a general increase in annual (especially winter) streamflow (Q) as early as 2030 across the DRB, with a larger increase by 2060. This increase in Q is the result of (1) higher winter PPT, which outweighs an annual actual evapotranspiration (AET) increase and (2) (for winter) a major shift away from storage of PPT as snow pack. However, when PET change is evaluated instead using the simpler T-based method of Hamon (1963), the increases in Q are small or even negative. In fact, the change of Q depends as much on PET method as on time period or RCP. This large sensitivity and associated uncertainty underscore the importance of exercising caution in the selection of a PET method for use in climate-change analyses.

From the NADP data collected within the region bounded by 35.6645 degree -48.782 degree north latitude and 124 degree -68 degree west longitude, similarities in latitudinal and longitudinal patterns of changing snow-season duration, fraction of annual precipitation recorded as snow, and the timing of chemical wet-deposition maxima, suggest that the chemical climate of the atmosphere is linked to physical changes in climate. Total annual precipitation depth has increased 4-6 % while snow season duration has decreased from approximately 7 to 21 days across most of the USA, except in higher elevation regions where it has increased by as much as 21 days. Snow-season precipitation is increasingly comprised of snow, but annually total precipitation is increasingly comprised of liquid precipitation. Meanwhile, maximum ammonium deposition occurs as much as 27 days earlier, and the maximum nitrate: sulfate concentration ratio in wet-deposition occurs approximately 10-21 days earlier in the year. The maximum crustal (calcium + magnesium + potassium) cation deposition occurs 2-35 days earlier in the year. The data suggest that these shifts in the timing of atmospheric wet deposition are linked to a warming climate, but the ecological consequences are uncertain.

To minimize the potential for future over-evacuations, multiple evacuation zones based on arrival time and inundation extent are being developed for California coastal communities. We use the coastal city of Alameda, California (USA), as a case study to explore population and evacuation implications associated with multiple tsunami-evacuation zones. We use geospatial analyses to estimate the number and type of people in each tsunami-evacuation zone and anisotropic pedestrian evacuation models to estimate pedestrian travel time out of each zone. Results demonstrate that there are tens of thousands of individuals in tsunami-evacuation zones on the two main islands of Alameda, but they will likely have sufficient time to evacuate before wave arrival. Quality of life could be impacted by the high number of government offices, schools, day-care centers, and medical offices in certain evacuation zones and by potentially high population density at one identified safe area after an evacuation. Multi-jurisdictional evacuation planning may be warranted, given that many at-risk individuals may need to evacuate to neighboring jurisdictions. The use of maximum evacuation zones for local tsunami sources may be warranted given the limited amount of available time to confidently recommend smaller zones which would result in fewer evacuees; however, this approach may also result in over-evacuation and the incorrect perception that successful evacuations are unlikely.

Fluid exchange within these low-hydraulic-gradient systems can occur across broad spatial and temporal scales, with variable contributions to material transport and transformation. Identifying and assessing the scales at which these processes operate is essential for accurate evaluations of how these systems contribute to global biogeochemical cycles. The distribution of super(222)Rn and super(223,224,226)Ra have complex spatial patterns along the Shark River Slough estuary (SRSE), Everglades, FL. High-resolution time-series measurements of super(222)Rn activity, salinity, and water level were used to quantify processes affecting radon fluxes out of the mangrove forest over a tidal cycle. Based on field data, tidal pumping through an extensive network of crab burrows in the lower FCE provides the best explanation for the high radon and fluid fluxes. Burrows are irrigated during rising tides when radon and other dissolved constituents are released from the mangrove soil. Flushing efficiency of the burrows-defined as the tidal volume divided by the volume of burrows-estimated for the creek drainage area vary seasonally from 25 (wet season) to 100 % (dry season) in this study. The tidal pumping of the mangrove forest soil acts as a significant vector for exchange between the forest and the estuary. Processes that enhance exchange of O sub(2) and other materials across the sediment-water interface could have a profound impact on the environmental response to larger scale processes such as sea level rise and climate change. Compounding the material budgets of the SRSE are additional inputs from groundwater from the Biscayne Aquifer, which were identified using radium isotopes. Quantification of the deep groundwater component is not obtainable, but isotopic data suggest a more prevalent signal in the dry season. These findings highlight the important role that both tidal- and seasonal-scale forcings play on groundwater movement in low-gradient hydrologic systems.

Our goal was to quantify distribution and growth of housing around the U.S. Fish and Wildlife Service National Wildlife Refuge System. This is important information for conservation planning, particularly given promotion of habitat connectivity as a climate change adaptation measure. We quantified housing growth from 1940 to 2000 and projected future growth to 2030 within three distances from refuges, identifying very low housing density open space, "opportunity areas" (contiguous areas with <6.17 houses/km super(2)), both nationally and by USFWS administrative region. Additionally, we quantified number and area of habitat corridors within these opportunity areas in 2000. Our results indicated that the number and area of open space opportunity areas generally decreased with increasing distance from refuges and with the passage of time. Furthermore, total area in habitat corridors was much lower than in opportunity areas. In addition, the number of corridors sometimes exceeded number of opportunity areas as a result of habitat fragmentation, indicating corridors are likely vulnerable to land use change. Finally, regional differences were strong and indicated some refuges may have experienced so much housing growth already that they are effectively too isolated to adapt to climate change, while others may require extensive habitat restoration work. Wildlife refuges are increasingly isolated by residential housing development, potentially constraining the movement of wildlife and, therefore, their ability to adapt to a changing climate.

AN - 1826706091; 27289222 AB - Lead (Pb) and calcium (Ca) concentrations were measured in fillet samples of longear sunfish (Lepomis megalotis) and redhorse suckers (Moxostoma spp.) collected in 2005-2012 from the Big River, which drains a historical mining area in southeastern Missouri and where a consumption advisory is in effect due to elevated Pb concentrations in fish. Lead tends to accumulated in Ca-rich tissues such as bone and scale. Concentrations of Pb in fish muscle are typically low, but can become elevated in fillets from Pb-contaminated sites depending in part on how much bone, scale, and skin is included in the sample. We used analysis-of-covariance to normalize Pb concentration to the geometric mean Ca concentration (415 ug/g wet weight, ww), which reduced variation between taxa, sites, and years, as was the number of samples that exceeded Missouri consumption advisory threshold (300 ng/g ww). Concentrations of Pb in 2005-2012 were lower than in the past, especially after Ca-normalization, but the consumption advisory is still warranted because concentrations were >300 ng/g ww in samples of both taxa from contaminated sites. For monitoring purposes, a simple linear regression model is proposed for estimating Ca-normalized Pb concentrations in fillets from Pb:Ca molar ratios as a way of reducing the effects of differing preparation methods on fillet Pb variation.

AN - 1826668887; 27110671 AB - Aquatic fungi contribute significantly to the decomposition of leaves in streams, a key ecosystem service. Little is known, however, about the effects of fungicides on aquatic fungi and macroinvertebrates involved with leaf decomposition. Red maple (Acer rubrum) leaves were conditioned in a stream to acquire microbes (bacteria and fungi) or leached in tap water (unconditioned) to simulate potential reduction of microbial biomass by fungicides. Conditioned leaves were exposed to fungicide formulations QUILT (azoxystrobin + propiconazole) or PRISTINE (boscalid + pyraclostrobin) in the presence and absence of the leaf shredder, Hyalella azteca (amphipods; 7-d old at start of exposures) for 14 d at 23 °C. The QUILT formulations (∼0.3 μg/L, 1.8 μg/L, and 8 μg/L) tended to increase leaf decomposition by amphipods (not significant) without a concomitant increase in amphipod biomass, indicating potential increased consumption of leaves with reduced nutritional value. The PRISTINE formulation (∼33 μg/L) significantly reduced amphipod growth and biomass (p < 0.05), effects similar to those observed with unconditioned controls. The significant suppressive effects of PRISTINE on amphipod growth and the trend toward increased leaf decomposition with increasing QUILT concentration indicate the potential for altered leaf decay in streams exposed to fungicides. Further work is needed to evaluate fungicide effects on leaf decomposition under conditions relevant to stream ecosystems, including temperature shifts and pulsed exposures to pesticide mixtures.

In the first section of the paper, we suggest the significance of incorporating inclusive design within the education of design disciplines. Then, we introduce a workshop on inclusive design awareness that architecture and interior design students participated, which applied various learner-centred methods. We discuss the process that incorporated project-based learning, role-playing/simulation and students' reflections and feedback on their experience. The workshop process, the student project experience and students' reflections on their learning indicate how multiple methods of learning engage students and enhance their empathic understanding so they can embrace differences and adopt a user-centred design approach. Based on the findings, we provide suggestions for similar educational events that can be applied in other disciplinary contexts.

AN - 1835688778; 27791330 AB - In the present study, existing regulatory frameworks and test systems for assessing potential endocrine active chemicals are described, and associated challenges are discussed, along with proposed approaches to address these challenges. Regulatory frameworks vary somewhat across geographies, but all basically evaluate whether a chemical possesses endocrine activity and whether this activity can result in adverse outcomes either to humans or to the environment. Current test systems include in silico, in vitro, and in vivo techniques focused on detecting potential endocrine activity, and in vivo tests that collect apical data to detect possible adverse effects. These test systems are currently designed to robustly assess endocrine activity and/or adverse effects in the estrogen, androgen, and thyroid hormone signaling pathways; however, there are some limitations of current test systems for evaluating endocrine hazard and risk. These limitations include a lack of certainty regarding: 1) adequately sensitive species and life stages; 2) mechanistic endpoints that are diagnostic for endocrine pathways of concern; and 3) the linkage between mechanistic responses and apical, adverse outcomes. Furthermore, some existing test methods are resource intensive with regard to time, cost, and use of animals. However, based on recent experiences, there are opportunities to improve approaches to and guidance for existing test methods and to reduce uncertainty. For example, in vitro high-throughput screening could be used to prioritize chemicals for testing and provide insights as to the most appropriate assays for characterizing hazard and risk. Other recommendations include adding endpoints for elucidating connections between mechanistic effects and adverse outcomes, identifying potentially sensitive taxa for which test methods currently do not exist, and addressing key endocrine pathways of possible concern in addition to those associated with estrogen, androgen, and thyroid signaling.

AN - 1815682942; 27369089 AB - Polonium-210 ((210)Po) is a naturally-occurring, carcinogenic member of the (238)U decay series and the granddaughter of (210)Pb. It has a half life of 138.4days and is rarely found in drinking water at levels exceeding 5mBq/L because it strongly binds to aquifer sediment. When the current US Maximum Contaminant Level (MCL) covering (210)Po was promulgated in December 2000, very little was known about its occurrence and the processes responsible for mobilizing it. More is now known about the processes that mobilize (210)Po from sediments and a review of recent occurrence data show that it may not be as rare in the US as the US Environmental Protection Agency (USEPA) thought in 2000. Worldwide, only about 2200 analyses for (210)Po in drinking water were identified, with activities exceeding 500mBq/L being found only in Finland, India, Sweden, and the US. The median of 400 (210)Po analyses from the US is 4.75mBq/L and >10% of the samples exceed 500mBq/L. Current compliance-monitoring regulations in the US essentially guarantee that (210)Po contamination will not be detected except in very contaminated wells. Major problems with the US Gross Alpha Activity MCL include the volatility of (210)Po and extended holding times and sample-compositing methods that can allow the majority of (210)Po in a sample bottle to decay before analysis. In light of new information, the radionuclide rule should be changed and direct measurements of (210)Po should be made in all public-water supply wells to rule out its presence. Much of the important biological and toxicological research on (210)Po is more than four decades old and new laboratory research using modern tools is needed. Biological and epidemiological investigations of known contaminated areas are needed to assess the effect (210)Po exposure is having on animals and humans consuming the water. Copyright © 2016.

AN - 1815682326; 27093907 AB - Methylmercury contamination of the environment is an important issue globally, and birds are useful bioindicators for mercury monitoring programs. The available data on mercury contamination of birds in western North America were synthesized. Original data from multiple databases were obtained and a literature review was conducted to obtain additional mercury concentrations. In total, 29219 original bird mercury concentrations from 225 species were compiled, and an additional 1712 mean mercury concentrations, representing 19998 individuals and 176 species, from 200 publications were obtained. To make mercury data comparable across bird tissues, published equations of tissue mercury correlations were used to convert all mercury concentrations into blood-equivalent mercury concentrations. Blood-equivalent mercury concentrations differed among species, foraging guilds, habitat types, locations, and ecoregions. Piscivores and carnivores exhibited the greatest mercury concentrations, whereas herbivores and granivores exhibited the lowest mercury concentrations. Bird mercury concentrations were greatest in ocean and salt marsh habitats and lowest in terrestrial habitats. Bird mercury concentrations were above toxicity benchmarks in many areas throughout western North America, and multiple hotspots were identified. Additionally, published toxicity benchmarks established in multiple tissues were summarized and translated into a common blood-equivalent mercury concentration. Overall, 66% of birds sampled in western North American exceeded a blood-equivalent mercury concentration of 0.2 μg/g wet weight (ww; above background levels), which is the lowest-observed effect level, 28% exceeded 1.0 μg/g ww (moderate risk), 8% exceeded 3.0 μg/g ww (high risk), and 4% exceeded 4.0 μg/g ww (severe risk). Mercury monitoring programs should sample bird tissues, such as adult blood and eggs, that are most-easily translated into tissues with well-developed toxicity benchmarks and that are directly relevant to bird reproduction. Results indicate that mercury contamination of birds is prevalent in many areas throughout western North America, and large-scale ecological attributes are important factors influencing bird mercury concentrations.

In this geomorphological framework, rainfall patterns, hydrological processes taking place within multi-layered ash-fall pyroclastic deposits and soil antecedent moisture status are the principal factors to be taken into account to assess triggering rainfall conditions and the related hazard. This paper presents the outcomes of an experimental study based on integrated analyses consisting of the reconstruction of physical models of landslides, in situ hydrological monitoring, and hydrological and slope stability modeling, carried out on four representative source areas of debris flows that occurred in May 1998 in the Sarno Mountain Range. The hydrological monitoring was carried out during 2011 using nests of tensiometers and Watermark pressure head sensors and also through a rainfall and air temperature recording station. Time series of measured pressure head were used to calibrate a hydrological numerical model of the pyroclastic soil mantle for 2011, which was re-run for a 12-year period beginning in 2000, given the availability of rainfall and air temperature monitoring data. Such an approach allowed us to reconstruct the regime of pressure head at a daily time scale for a long period, which is representative of about 11 hydrologic years with different meteorological conditions. Based on this simulated time series, average winter and summer hydrological conditions were chosen to carry out hydrological and stability modeling of sample slopes and to identify Intensity-Duration rainfall thresholds by a deterministic approach. Among principal results, the opposing winter and summer antecedent pressure head (soil moisture) conditions were found to exert a significant control on intensity and duration of rainfall triggering events. Going from winter to summer conditions requires a strong increase of intensity and/or duration to induce landslides. The results identify an approach to account for different hazard conditions related to seasonality of hydrological processes inside the ash-fall pyroclastic soil mantle. Moreover, they highlight another important factor of uncertainty that potentially affects rainfall thresholds triggering shallow landslides reconstructed by empirical approaches.

On the time-scale of glacial-interglacial sea-level cycles, fluvial incision of exposed barrier reef lagoons may compete with constructional coral growth to shape the coastal geomorphology of ocean islands. However, overprinting of Pleistocene landscapes by Holocene erosion or sedimentation has largely obscured the role lowstand river incision may have played in developing the deep lagoons typical of modern barrier reefs. Here we use high-resolution seismic imagery and core stratigraphy to examine how erosion and/or deposition by upland drainage networks has shaped coastal morphology on Tahaa, a barrier reef-bound island located along the Society Islands hotspot chain in French Polynesia. At Tahaa, we find that many channels, incised into the lagoon floor during Pleistocene sea-level lowstands, are located near the mouths of upstream terrestrial drainages. Steeper antecedent topography appears to have enhanced lowstand fluvial erosion along Tahaa's southwestern coast and maintained a deep pass. During highstands, upland drainages appear to contribute little sediment to refilling accommodation space in the lagoon. Rather, the flushing of fine carbonate sediment out of incised fluvial channels by storms and currents appears to have limited lagoonal infilling and further reinforced development of deep barrier reef lagoons during periods of highstand submersion.

Decomposition of soil organic matter (SOM) contributes to the production and turnover of dissolved organic matter (DOM). While temperature is a primary control on rates of SOM and DOM cycling, little is known about temperature effects on DOM composition in soil leachate. Here we conducted a 30day incubation to examine the effects of temperature (20 versus 5 degree C) and SOM decomposition state (moss versus fibric versus amorphous horizons) on DOM composition in organic soils of interior Alaska. We characterized DOM using bulk dissolved organic C (DOC) concentration, chemical fractionation, optical properties, and ultrahigh-resolution mass spectrometry. We observed an increase in DOC concentration and DOM aromaticity in the 20 degree C treatment compared to the 5 degree C treatment. Leachate from fibric horizons had higher DOC concentration than shallow moss or deep amorphous horizons. We also observed chemical shifts in DOM leachate over time, including increases in hydrophobic organic acids, polyphenols, and condensed aromatics and decreases in low-molecular weight hydrophilic compounds and aliphatics. We compared ultrahigh-resolution mass spectrometry and optical data and observed strong correlations between polyphenols, condensed aromatics, SUVA sub(254), and humic-like fluorescence intensities. These findings suggest that biolabile DOM was preferentially mineralized, and the magnitude of this transformation was determined by kinetics (i.e., temperature) and substrate quality (i.e., soil horizon). With future warming, our findings indicate that organic soils may release higher concentrations of aromatic DOM to aquatic ecosystems. Key Points * Temperature is a primary control on the production, transformation, and turnover of DOM leached from boreal soils * Organic-horizon depth and decomposition state strongly influence DOM composition in soil leachate * High-resolution molecular data and simple optical measurements shed light on DOM transformation over time JF - Journal of Geophysical Research.

Reconstruction quality is enhanced by incorporating tree-ring chronologies where high snowpack limits growth, which better represent the contribution of cool-season precipitation to flow than chronologies from trees positively sensitive to hydroclimate alone. The best performing reconstruction (back to 1609 CE) explains 59% of the historical variability and the longest reconstruction (back to 1502 CE) explains 52% of the variability. Droughts similar to the high-intensity, long-duration low flows observed during the 1920s and 1940s are rare, but occurred in the early 1500s and 1630s-1640s. The lowest Columbia flow events appear to be reflected in chronologies both positively and negatively related to streamflow, implying low snowpack and possibly low warm-season precipitation. High flows of magnitudes observed in the instrumental record appear to have been relatively common, and high flows from the 1680s to 1740s exceeded the magnitude and duration of observed wet periods in the late-19th and 20th Century. Comparisons between the Columbia River reconstructions and future projections of streamflow derived from global climate and hydrologic models show the potential for increased hydrologic variability, which could present challenges for managing water in the face of competing demands.

Specifically, we assess how the above decisions affect: (i) historical simulation of signature measures of hydrologic behavior, and (ii) projected changes in terms of annual water balance and hydrologic signature measures. To this end, we conduct our study in three catchments located in the headwaters of the Colorado River basin. Meteorological forcings for current and a future climate projection are obtained at three spatial resolutions (4-, 12- and 36-km) from dynamical downscaling with the Weather Research and Forecasting (WRF) regional climate model, and hydrologic changes are computed using four different hydrologic model structures. These projected changes are compared to those obtained from running hydrologic simulations with current and future 4-km WRF climate outputs re-scaled to 12- and 36-km. The results show that the horizontal resolution of WRF simulations heavily affects basin-averaged precipitation amounts, propagating into large differences in simulated signature measures across model structures. The implications of re-scaled forcing datasets on historical performance were primarily observed on simulated runoff seasonality. We also found that the effects of WRF grid resolution on projected changes in mean annual runoff and evapotranspiration may be larger than the effects of hydrologic model choice, which surpasses the effects from re-scaled forcings. Scaling effects on projected variations in hydrologic signature measures were found to be generally smaller than those coming from WRF resolution; however, forcing aggregation in many cases reversed the direction of projected changes in hydrologic behavior.

Over the last 30 years, the Cl flux in YNP Rivers has been calculated using discharge measurements and Cl concentrations determined in discrete water samples and it has been determined that approximately 12% of the Cl flux exiting YNP is from the Snake River. The relationship between electrical conductivity and concentrations of Cl and other geothermal solutes was quantified at a monitoring site located downstream from the thermal inputs in the Snake River. Beginning in 2012, continuous (15 min) electrical conductivity measurements have been made at the monitoring site. Combining continuous electrical conductivity and discharge data, the Cl and other geothermal solute fluxes were determined. The 2013-2015 Cl fluxes (5.3-5.8 kt/yr) determined using electrical conductivity are comparable to historical data. In addition, synoptic water samples and discharge data were obtained from sites along the Snake River under low-flow conditions of September 2014. The synoptic water study extended 17 km upstream from the monitoring site. Surface inflows were sampled to identify sources and to quantify solute loading. The Lewis River was the primary source of Cl, Na, K, Cl, SiO (sub 2) , Rb, and As loads (50-80%) in the Snake River. The largest source of SO (sub 4) was from the upper Snake River (50%).

Lower uric acid in affected birds was the only difference detected between groups, although sample sizes were small. This difference could be associated with fasting or malnutrition in birds with beak deformities, but it is challenging to interpret its biologic significance without reference values. Black-capped Chickadees had high levels of aspartate aminotransferase, lactate dehydrogenase, and creatine kinase relative to reference values for companion birds. However, all serum chemistry parameters from our study were within the range of values reported from other apparently healthy wild-caught birds.

Accounting for Culture in Fish and Wildlife Management in Rural Alaska AN - 1837069662 AB - The Alaska National Interest Lands Conservation Act of 1980 requires federal agencies to provide a meaningful role for rural subsistence harvesters in management of fish and wildlife in Alaska. We constructed an interpretive analysis of qualitative interviews with residents of the Yukon-Kuskokwim Delta. Stakeholders' perceptions of their roles and motivations to participate in collaborative management are linked to unseen and often ignored cultural features and differing worldviews that influence outcomes of collaboration. Agencies need to better understand Yup'ik preferences for working together and change their formats and methods of public engagement. More frequent and higher quality interactions among stakeholders in rural communities will create awareness of cultural differences. Improved awareness will allow managers to design and implement a process that is culturally appropriate and increase the meaningfulness of collaborative management.

AN - 1827931906; PQ0003689847 AB - In the Prairie Pothole Region of North America, disturbances to wetlands that disrupt water-level fluctuations in response to wet-dry climatic conditions have the potential to alter natural vegetative communities in favor of species that proliferate in stable environments, such as cattail (Typha spp.). We evaluated the effect of water-level dynamics during a recent fluctuation in wet-dry conditions on cattail coverage within semipermanently and permanently ponded wetlands situated in watersheds with different land use and amounts of wetland drainage. We found that ponded water depth increase was significantly greater in wetlands where water levels were not near the spill point of the topographic basin, where banks were steeper, and in larger wetlands where past dry conditions had less influence on change in pond area. Proportion of the wetland covered by cattail was negatively correlated with increased water depth, bank slope and pond area. Our observations provide evidence that cattail coverage in prairie wetlands is regulated by water-level fluctuations and that land use surrounding the wetland might have an indirect effect on cattail coverage by altering water-level response to wet-dry climate conditions. For example, drainage of smaller wetlands into larger wetlands that are characterized by more permanent hydroperiods, leads to stabilized water levels near their spill point and is therefore a potential mechanism for increased cattail abundance in the northern prairie region.

HSC can be developed through numerous methods; however, few studies have evaluated the consistency of HSC developed by different methodologies. We directly compared HSC for depth and velocity developed by the Delphi method (expert opinion) and by two primary literature meta-analyses (literature-derived range and interquartile range) to assess whether these independent methods produce analogous criteria for multiple species (rainbow trout, brown trout, American shad, and shallow fast guild) and life stages. We further evaluated how these two independently developed HSC affect calculations of habitat availability under three alternative reservoir management scenarios in the upper Delaware River at a mesohabitat (main channel, stream margins, and flood plain), reach, and basin scale. In general, literature-derived HSC fell within the range of the Delphi HSC, with highest congruence for velocity habitat. Habitat area predicted using the Delphi HSC fell between the habitat area predicted using two literature-derived HSC, both at the basin and the site scale. Predicted habitat increased in shallow regions (stream margins and flood plain) using literature-derived HSC while Delphi-derived HSC predicted increased channel habitat. HSC generally favoured the same reservoir management scenario; however, no favoured reservoir management scenario was the most common outcome when applying the literature range HSC. The differences found in this study lend insight into how different methodologies can shape HSC and their consequences for predicted habitat and water management decisions.

Consequently, we examined the diel feeding ecology of subyearling rainbow trout (Oncorhynchus mykiss) during winter in a central New York stream. Rainbow trout diet was significantly different during each 4-h interval and also differed from the drift and benthos. Feeding was significantly greater during darkness (i.e. 20:00 h - 04:00 h) than during daylight hours (i.e. 08:00 h - 16:00 h), peaking at 20:00 h. Daily food consumption (1.9 mg) and daily ration (3.4 %) during winter were substantially lower than previously reported for subyearling rainbow trout in the same stream during summer. These findings provide important new insights into the winter feeding ecology of juvenile rainbow trout in streams.

In 2016, the U.S. Geological Survey sampled 46 wells in the area to characterize the nature and extent of chromium in groundwater, to understand what proportion of total chromium is in the hexavalent state, and to determine if substantial differences are present between filtered and unfiltered chromium concentrations. Results indicate detectable chromium concentrations in all wells, over 75 % of total chromium is in the hexavalent state in a majority of wells, and filtered and unfiltered results differ substantially in only a few high-turbidity total chromium samples.

The resultant contamination adversely affected biota and caused human health problems and risks. Remediation in the Superfund site requires an understanding of the magnitude and extent of contamination. To provide some of the required information, a series of sediment and soil investigations were conducted in and near the Superfund site to characterize lead and zinc contamination in the aquatic and floodplain environments along the main-stem Spring River and its major tributaries. In the Superfund site, the most pronounced lead and zinc contamination, with concentrations that far exceed sediment quality guidelines associated with potential adverse biological effects, was measured for streambed sediments and floodplain soils located within or downstream from the most intensive mining-affected areas. Tributary streambeds and floodplains in affected areas are heavily contaminated with some sites having lead and zinc concentrations that are an order of magnitude (or more) greater than the sediment quality guidelines. For the main-stem Spring River, the streambed is contaminated but the floodplain is mostly uncontaminated. Measured lead and zinc concentrations in streambed sediments, lakebed sediments, and floodplain soils documented a persistence of the post-mining contamination on a decadal timescale.

Unlike many streams, the canopy in a reservoir shades only a narrow fringe of water adjacent to the shoreline, and may not have the influential effect on the aquatic environment reported in streams. We compared fish assemblages between shaded and unshaded sites in a shallow reservoir. Overall species richness (gamma diversity) was higher in shaded sites, and fish assemblage composition differed between shaded and unshaded sites. Average light intensity was 66 % lower in shaded sites, and differences in average temperature and dissolved oxygen were small. Unlike streams where shade can have large effects on water physicochemistry, in reservoirs shade-related differences in fish assemblages seemed to be linked principally to differences in light intensity. Diversity in light intensity in shaded and unshaded sites in reservoirs can create various mosaics of light-based habitats that enable diversity of species assemblages. Managing to promote the habitat diversity provided by shade may require coping with the artificial nature of reservoir riparian zones and water level fluctuations.

In this paper, we mapped hot and cold spots for perceived and modeled ecosystem services by synthesizing results from a social-values mapping study of residents living near the Pike-San Isabel National Forest (PSI), located in the Southern Rocky Mountains, with corresponding biophysically modeled ecosystem services. Social-value maps for the PSI were developed using the Social Values for Ecosystem Services tool, providing statistically modeled continuous value surfaces for 12 value types, including aesthetic, biodiversity, and life-sustaining values. Biophysically modeled maps of carbon sequestration and storage, scenic viewsheds, sediment regulation, and water yield were generated using the Artificial Intelligence for Ecosystem Services tool. Hotspots for both perceived and modeled services were disproportionately located within the PSI's wilderness areas. Additionally, we used regression analysis to evaluate spatial relationships between perceived biodiversity and cultural ecosystem services and corresponding biophysical model outputs. Our goal was to determine whether publicly valued locations for aesthetic, biodiversity, and life-sustaining values relate meaningfully to results from corresponding biophysical ecosystem service models. We found weak relationships between perceived and biophysically modeled services, indicating that public perception of ecosystem service provisioning regions is limited. We believe that biophysical and social approaches to ecosystem service mapping can serve as methodological complements that can advance ecosystem services-based resource management, benefitting resource managers by showing potential locations of synergy or conflict between areas supplying ecosystem services and those valued by the public.

Projections based on widely used static modeling methods implicitly assume that species are in equilibrium with the environment and that detection during surveys is perfect. We used multiseason correlated detection occupancy models, which avoid these assumptions, to relate climate data to distributional shifts of Louisiana Waterthrush in the North American Breeding Bird Survey (BBS) data. We summarized these shifts with indices of range size and position and compared them to the same indices obtained using more basic modeling approaches. Detection rates during point counts in BBS surveys were low, and models that ignored imperfect detection severely underestimated the proportion of area occupied and slightly overestimated mean latitude. Static models indicated Louisiana Waterthrush distribution was most closely associated with moderate temperatures, while dynamic occupancy models indicated that initial occupancy was associated with diurnal temperature ranges and colonization of sites was associated with moderate precipitation. Overall, the proportion of area occupied and mean latitude changed little during the 1997-2013 study period. Near-term forecasts of species distribution generated by dynamic models were more similar to subsequently observed distributions than forecasts from static models. Occupancy models incorporating a finite mixture model on detection - a new extension to correlated detection occupancy models - were better supported and may reduce bias associated with detection heterogeneity. We argue that replacing phenomenological static models with more mechanistic dynamic models can improve projections of future species distributions. In turn, better projections can improve biodiversity forecasts, management decisions, and understanding of global change biology.

Here we show that seismic energy created by an induced earthquake and an artificial reservoir has spectral content coincident with the natural modes of vibration of a prominent rock bridge. We measured the resonant frequencies of Rainbow Bridge, Utah using data from two broadband seismometers placed on the span, and identified eight distinct vibrational modes between 1 and 6 Hz. A distant, induced earthquake produced local ground motion rich in 1 Hz energy, stimulating a 20 dB increase in measured power at the bridge's fundamental mode. Moreover, we establish that wave action on Lake Powell, an artificial reservoir, generates microseismic energy with peak power approximately 1 Hz, also exciting resonance of Rainbow Bridge. These anthropogenic sources represent relatively new energy input for the bridge with unknown consequences for structural fatigue. Abstract Copyright (2016), . American Geophysical Union.

By examining Japanese K-NET data averaged in bins partitioned by M (sub w) and hypocentral distance, we demonstrate that the P wave displacement briefly displays similar growth at the onset of rupture and that the departure time (T (sub dp) ), which is defined as the time of departure from similarity of the absolute displacement after applying a band-pass filter, correlates with the final M in a range of 4.5 < or = M (sub w) < or = 7. The scaling relation between M (sub w) and T (sub dp) implies that useful information on the final M can be derived while the event is still in progress because T (sub dp) occurs before the completion of rupture. We conclude that the scaling relation is important not only for earthquake early warning but also for the source physics of earthquakes. Abstract Copyright (2016), . American Geophysical Union.

AN - 1817561713; 27434394 AB - The critically endangered California condor (Gymnogyps californianus) has relied intermittently on dead-stranded marine mammals since the Pleistocene, and this food source is considered important for their current recovery. However, contemporary marine mammals contain persistent organic pollutants that could threaten condor health. We used stable carbon and nitrogen isotope, contaminant, and behavioral data in coastal versus noncoastal condors to quantify contaminant transfer from marine mammals and created simulation models to predict the risk of reproductive impairment for condors from exposure to DDE (p,p'-DDE), a major metabolite of the chlorinated pesticide DDT. Coastal condors had higher whole blood isotope values and mean concentrations of contaminants associated with marine mammals, including mercury (whole blood), sum chlorinated pesticides (comprised of ∼95% DDE) (plasma), sum polychlorinated biphenyls (PCBs) (plasma), and sum polybrominated diphenyl ethers (PBDEs) (plasma), 12-100-fold greater than those of noncoastal condors. The mean plasma DDE concentration for coastal condors was 500 ± 670 (standard deviation) (n = 22) versus 24 ± 24 (standard deviation) (n = 8) ng/g of wet weight for noncoastal condors, and simulations predicted ∼40% of breeding-age coastal condors have DDE levels associated with eggshell thinning in other avian species.

Here we present a data set of distributed stream stage, streamflow, stream temperature, barometric pressure, and air temperature from the Tuolumne River Watershed in Yosemite National Park, Sierra Nevada, California, USA, for water years 2002-2015, as well as a quality-controlled hourly meteorological forcing time series for use in hydrologic modeling. We also provide snow data and daily inflow to the Hetch Hetchy Reservoir for 1970-2015. This paper describes data collected using low-visibility and low-impact installations for wilderness locations and can be used alone or as a critical supplement to ancillary data sets collected by cooperating agencies, referenced herein. This data set provides a unique opportunity to understand spatial patterns and scaling of hydroclimatic processes in complex terrain and can be used to evaluate downscaling techniques or distributed modeling. The paper also provides an example methodology and lessons learned in conducting hydroclimatic monitoring in remote wilderness. Abstract Copyright (2016), . American Geophysical Union.

The Network has three aims: (1) provide data to support understanding of basic aeolian processes across land use types, land cover types, and management practices, (2) support development and application of models to assess wind erosion and dust emission and their impacts on human and environmental systems, and (3) encourage collaboration among the aeolian research community and resource managers for the transfer of wind erosion technologies. The Network currently consists of thirteen intensively instrumented sites providing measurements of aeolian sediment transport rates, meteorological conditions, and soil and vegetation properties that influence wind erosion. Network sites are located across rangelands, croplands, and deserts of the western US. In support of Network activities, http://winderosionnetwork.org was developed as a portal for information about the Network, providing site descriptions, measurement protocols, and data visualization tools to facilitate collaboration with scientists and managers interested in the Network and accessing Network products. The Network provides a mechanism for engaging national and international partners in a wind erosion research program that addresses the need for improved understanding and prediction of aeolian processes across complex and diverse land use types and management practices.

Adinotherium, a Peltephilidae armadillo, the freshwaters fishes Platysilurus and Phractocephalus, the caiman Purussaurus, an indeterminate dolphin, turtles, and the previously recognized sloth Pseudoprepotherium venezuelanum. When compared with the higher latitudes faunas of Argentina and Chile, the presence of cf. Adinotherium and peltephilids in the Rio Yuca Formation is consistent, but not conclusive, with a Santacrucian to Frisian SALMA age. The associated fauna, as well recent apatite fission track analysis, indicates that the Rio Yuca assemblage is more likely younger in age, specifically Middle to Late Miocene. So far, the Miocene localities of the northern part of South America have provided a less prolific fossil record compared to the southern part of the continent (e.g., Santacrucian and Friasian faunas of Patagonia), but the present work documents the surprising occurrence of two taxa (Peltephilidae and Nesodontinae) common in southern high latitude faunas of South America, implying the persistence of the Santacrucian-Friasian genus Adinotherium in younger strata from northern South America, and that peltephilids were much more widespread during the Miocene than previously recognized. The presence of these common Patagonian taxa (Peltephilidae and Nesodontinae) in Rio Yuca also supports the hypothesis of prior researchers for the existence of biogeographical connections between the northern and southern portions of South America during the Late Oligocene or Early Miocene, which facilitated faunal interchange between the two regions. Finally, the biogeographical affinities of the freshwater fishes and the giant caiman (Purussaurus) indicate close relationships of the Tucupido region with the ancestral distribution of the Orinocoan-Amazonian drainage system.

Numerous models have been developed to predict river temperature. However, many were not designed to predict thermally stressful periods. Because such events are rare, traditionally applied analyses are inappropriate. Here, we developed two logistic regression models to predict thermally stressful events in the Delaware River at the US Geological Survey gage near Lordville, New York. One model predicted the probability of an event >20.0 degree C, and a second predicted an event >22.2 degree C. Both models were strong (independent test data sensitivity 0.94 and 1.00, specificity 0.96 and 0.96) predicting 63 of 67 events in the >20.0 degree C model and all 15 events in the >22.2 degree C model. Both showed negative relationships with released volume from the upstream Cannonsville Reservoir and positive relationships with difference between air temperature and previous day's water temperature at Lordville. We further predicted how increasing release volumes from Cannonsville Reservoir affected the probabilities of correctly predicted events. For the >20.0 degree C model, an increase of 0.5 to a proportionally adjusted release (that accounts for other sources) resulted in 35.9% of events in the training data falling below cutoffs; increasing this adjustment by 1.0 resulted in 81.7% falling below cutoffs. For the >22.2 degree C these adjustments resulted in 71.1% and 100.0% of events falling below cutoffs. Results from these analyses can help managers make informed decisions on alternative release scenarios.

We used acoustic telemetry to determine the current and possible future role of traps to control and assess invasive sea lampreys, Petromyzon marinus, in the St. Marys River, the connecting channel between Lake Superior and Lake Huron. Exploitation rates (i.e., fractions of an adult sea lamprey population removed by traps) at two upstream locations were compared among three years and two points of entry to the system. Telemetry receivers throughout the drainage allowed trap performance (exploitation rate) to be partitioned into two components: proportion of migrating sea lampreys that visited trap sites (availability) and proportion of available sea lampreys that were caught by traps (local trap efficiency). Estimated exploitation rates were well below those needed to provide population control in the absence of lampricides and were limited by availability and local trap efficiency. Local trap efficiency estimates for acoustic-tagged sea lampreys were lower than analogous estimates regularly obtained using traditional mark-recapture methods, suggesting that abundance had been previously underestimated. Results suggested major changes would be required to substantially increase catch, including improvements to existing traps, installation of new traps, or other modifications to attract and retain more sea lampreys. This case study also shows how bias associated with telemetry tags can be estimated and incorporated in models to improve inferences about parameters that are directly relevant to fishery management.

The role of fault system geometry in describing ECSZ deformation may be investigated with total variation regularization, which algorithmically determines a best-fitting geometry from an initial model with numerous faults, constrained by a western United States GPS velocity field. The initial dense model (1) enables construction of the first geodetically constrained block model to include all ECSZ faults with geologic slip rates, allowing direct geologic-geodetic slip rate comparisons, and (2) permits fault system geometries with many active faults that are analogous to distributed interseismic deformation. Beginning with 58 ECSZ blocks, a model containing 10 ECSZ blocks is most consistent with geologic slip rates, reproducing five of 11 within their reported uncertainties. The model fits GPS observations with a mean residual velocity of 1.5 mm/yr. Persistent geologic-geodetic slip rate discrepancies occur on the Calico and Garlock faults, on which we estimate slip rates of 7.6 mm/yr and <2 mm/yr, respectively, indicating that inconsistencies between geology and geodesy may be concentrated on or near these faults and are not due to pervasive distributed deformation in the region. Discrepancies may in part be due to postseismic relaxation following the A.D. 1992 M sub(w) 7.3 Landers and 1999 M sub(w) 7.1 Hector Mine earthquakes. Otherwise, resolving geologic-geodetic discrepancies would require as much as 11.4 mm/yr of off-fault deformation within <10 km of the main ECSZ faults, with similar to 5 mm/yr concentrated near the Calico fault.

To assess species' vulnerability to climate change and target ongoing conservation investments, researchers and managers often consider the effects of projected changes in climate and land use on future habitat availability and quality and the uncertainty associated with these projections. Here, we draw on tools from hydrology and climate science to project the impact of climate change on the density of wetlands in the Prairie Pothole Region of the USA, a critical area for breeding waterfowl and other wetland-dependent species. We evaluate the potential for a trade-off in the value of conservation investments under current and future climatic conditions and consider the joint effects of climate and land use. We use an integrated set of hydrological and climatological projections that provide physically based measures of water balance under historical and projected future climatic conditions. In addition, we use historical projections derived from ten general circulation models (GCMs) as a baseline from which to assess climate change impacts, rather than historical climate data. This method isolates the impact of greenhouse gas emissions and ensures that modeling errors are incorporated into the baseline rather than attributed to climate change. Our work shows that, on average, densities of wetlands (here defined as wetland basins holding water) are projected to decline across the U.S. Prairie Pothole Region, but that GCMs differ in both the magnitude and the direction of projected impacts. However, we found little evidence for a shift in the locations expected to provide the highest wetland densities under current vs. projected climatic conditions. This result was robust to the inclusion of projected changes in land use under climate change. We suggest that targeting conservation towards wetland complexes containing both small and relatively large wetland basins, which is an ongoing conservation strategy, may also act to hedge against uncertainty in the effects of climate change.

AN - 1826662352; 27010754 AB - Two groundwater plumes in north central Minnesota with residual crude oil sources have 20 to 50 mg/L of nonvolatile dissolved organic carbon (NVDOC). These values are over 10 times higher than benzene and two to three times higher than Diesel Range Organics in the same wells. On the basis of previous work, most of the NVDOC consists of partial transformation products from the crude oil. Monitoring data from 1988 to 2015 at one of the sites located near Bemidji, MN show that the plume of metabolites is expanding toward a lakeshore located 335 m from the source zone. Other mass balance studies of the site have demonstrated that the plume expansion is driven by the combined effect of continued presence of the residual crude oil source and depletion of the electron accepting capacity of solid phase iron oxide and hydroxides on the aquifer sediments. These plumes of metabolites are not covered by regulatory monitoring and reporting requirements in Minnesota and other states. Yet, a review of toxicology studies indicates that polar metabolites of crude oil may pose a risk to aquatic and mammalian species. Together the results suggest that at sites where residual sources are present, monitoring of NVDOC may be warranted to evaluate the fates of plumes of hydrocarbon transformation products.

These models typically include nonlinear descriptions of ecological processes and as a result may be sensitive to how model inputs are summarized because of a mathematical property of nonlinear equations known as Jensen's inequality. In particular, we show that the way in which continuous size distributions of invertebrate prey are represented within foraging models can lead to biases within the modeling process. We begin by illustrating how different equations common to drift-foraging models are sensitive to invertebrate inputs. We then use two case studies to show how different representations of invertebrate prey can influence predictions of energy intake and lifetime growth. Greater emphasis should be placed on accurate characterizations of invertebrate drift, acknowledging that inferences from drift-foraging models may be influenced by how invertebrate prey are represented.

Basic data were obtained for implementing the REDD mechanism in the Democratic People's Republic of Korea (DPRK) for scientific decision-making to prevent deforestation and forest degradation. The potential effects according to the implementation of the REDD mechanism in the DPRK based on forest status data (the latest) are as follows. If the deforestation rate is reduced to a level below 6% through a 20-year REDD mechanism beginning in 2011, 0.01-11.64 C-tons of carbon credit per ha could be issued for DPRK. Converted into CO sub(2)-tons per ha, this amounts to 0.03-42.68 CO sub(2)-tons, which translates to a minimum of 226,000 CO sub(2)-tons and a maximum of 289,082,000 CO sub(2)-tons overall for forests in DPRK. In terms of carbon price, this measures up to 1.10 million USD-1.4 billion USD, considering that the REDD carbon price in voluntary carbon markets in 2010 was around 5 USD.

Such a decision-analytic focus uses the products of climate science as probabilistic predictions about the effects of management policies. Here we present methods to detect when climate predictions are failing to capture the system dynamics. For a single model, we measure goodness of fit based on the empirical distribution function, and define failure when the distribution of observed values significantly diverges from the modelled distribution. For a set of models, the same statistic can be used to provide relative weights for the individual models, and we define failure when there is no linear weighting of the ensemble models that produces a satisfactory match to the observations. Early detection of failure of a set of predictions is important for improving model predictions and the decisions based on them. We show that these methods would have detected a range shift in northern pintail 20 years before it was actually discovered, and are increasingly giving more weight to those climate models that forecast a September ice-free Arctic by 2055.

To compare and contrast how understanding of population ecology is useful for control programs in the Great Lakes and restoration programs in Europe, we review current understanding of the population ecology of the sea lamprey in its native and introduced range. Some attributes of sea lamprey population ecology are particularly useful for both control programs in the Great Lakes and restoration programs in the native range. First, traps within fish ladders are beneficial for removing sea lampreys in Great Lakes streams and passing sea lampreys in the native range. Second, attractants and repellants are suitable for luring sea lampreys into traps for control in the Great Lakes and guiding sea lamprey passage for conservation in the native range. Third, assessment methods used for targeting sea lamprey control in the Great Lakes are useful for targeting habitat protection in the native range. Last, assessment methods used to quantify numbers of all life stages of sea lampreys would be appropriate for measuring success of control in the Great Lakes and success of conservation in the native range.

We assessed whether increased phosphorus (P) levels in litter and soil influenced decomposition rates and litter nutrient dynamics of foliage, fine roots, and twigs in nitrogen (N)-rich Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests in the Oregon Coast Range. We decomposed fresh foliage, fine root, and twig litter from Douglas-fir seedlings at three sites for two years. Half of the seedlings and half of the plots at each of the sites were fertilized with P resulting in a factorial design with the following treatments: control (no P fertilization), plant P (P-fertilized litter), soil P (P-fertilized soil), and plant P soil P. Soil P fertilization slightly decreased foliage decomposition rates. Fertilization of seedlings increased litter P concentrations by an average of 250 % relative to controls, but did not alter litter decomposition rates. Litter fertilized with P mineralized P rapidly and early in the decomposition process compared to N. Litter P concentrations decreased over the 2 years for all treatments, whereas N concentrations increased. Decomposition rates and loss of N and P were strongly related to initial litter chemistry. Despite different initial litter C:N:P ratios in P fertilized seedlings, ratios of C:N, C:P and N:P converged to similar values across treatments within a given litter type over 2 years. We conclude that litter P concentrations and to some extent soil P may influence litter nutrient dynamics during decomposition, resulting in a convergence of element ratios that reflect the balance of substrate decomposition and microbial nutrient stoichiometry.

These changes occur over distances of tens of meters (m) implying rapid removal kinetics of the chromophoric DOM that imparts color to groundwater. A one-compartment input-output model was used to derive a differential equation describing the removal of DOM from the dissolved phase due to the combined effects of biodegradation and sorption. The general solution to the equation was parameterized using a 2-year record of dissolved organic carbon (DOC) concentration changes in groundwater at a long-term observation well. Estimated rates of DOC loss were rapid and ranged from 0.093 to 0.21 micromoles per liter per day ( mu M d super(-1)), and rate constants for DOC removal ranged from 0.0021 to 0.011 per day (d super(-1)). Applying these removal rate constants to an advective-dispersion model illustrates substantial depletion of DOC over flow-path distances of 200 m or less and in timeframes of 2 years or less. These results explain the low to moderate DOC concentrations (20-75 mu M; 0.26-1 mg L super(-1)) and ultraviolet absorption coefficient values (a sub(254)<5 m super(-1)) observed in groundwater produced from 59 wells tapping eight different aquifer systems of the United States. The nearly uniform optical clarity of groundwater, therefore, results from similarly rapid DOM-removal kinetics exhibited by geologically and hydrologically dissimilar aquifers.Original Abstract: Les concentrations de la matiere organique dissoute (MOD) et l'absorption dans l'ultraviolet decroissent systematiquement quand l'eau souterraine se deplace a travers les zones non saturees au-dessus et a l'interieur des aquiferes et dans la zone saturee des aquiferes. Ces variations se produisent sur quelques dizaines de metres de distance ce qui implique des cinetiques d'elimination rapide des MOD chromophores qui donnent sa couleur a l'eau souterraine. Un modele a un compartiment d'entree-sortie a ete utilise pour deriver l'equation differentielle representant l'elimination de la MOD de la phase dissoute due aux effets combines de la biodegradation et de la sorption. La solution generale de l'equation a ete parametree en utilisant l'enregistrement sur deux ans des variations a long terme de la concentration dans l'eau souterraine du carbone organique dissous (COD) sur un piezometre. Les taux estimes de perte de MOD sont rapides, compris entre 0.093 et 0.210 micromoles par litre et par jour ( mu M d super(-1)), et les constantes de taux d'elimination de la MOD sont comprises entre 0.0021 et 0.011 par jour (j super(-1)). L'application de ces constantes de taux d'elimination a un modele d'advection-dispersion illustre de substantielles diminutions de la MOD chromophore sur des distances d'ecoulement de 200 m ou moins et dans des laps de temps de deux ans ou moins. Ces resultats expliquent les concentrations faibles a moderees en COD (20-75 mu M ; 0.26-1 mg L super(-1)) et les valeurs du coefficient d'absorption dans l'ultraviolet (a sub(254)<5 m super(-1)) observees dans les eaux souterraines plus agees prelevees dans 59 puits exploitant 8 systemes aquiferes differents des Etats-Unis d'Amerique. La clarte optique quasi uniforme des eaux souterraines resulte, par consequent, des cinetiques identiquement rapides de l'elimination de la MOD presentees par des aquiferes differents du point de vue geologique et hydrogeologique.

Intermittent injection testing began in 1991, followed by near-continuous injection since 1996. Daily average injection flow rates and surface injection pressures have been recorded since 1991, and seismicity has been monitored since 1985. Before the injection flow rate was decreased in 2013 in response to the largest induced earthquake to date, observed wellhead pressures were increasing and approaching the maximum permitted pressure. Potential solutions were needed to provide long-term reductions in wellhead pressures and to minimize the occurrence of future large-magnitude induced earthquakes. A key step in this process is to establish whether the trend of increasing pressures is more likely caused by far-field reservoir pressurization or near-well flow impairment. The spatiotemporal occurrence of induced seismicity is fit relatively well by a 1D diffusive triggering front relationship, suggesting that the reservoir can be modeled as a porous medium. Simple 1D, uncoupled porous models are therefore used to analyze the wellhead pressure response for the period of long-term injection. These simple models are found to provide a reasonable fit to the pressure/flow data. We did not observe the expected changes in the model parameters that would indicate significant near-well flow impairment, and thus we have concluded that the observed pressure increase is more likely related to far-field pressurization. Somewhat surprisingly, given the complex geologic structure and the heterogeneity in the locations of induced seismicity, the analysis demonstrates the ability of a simple radially symmetric porous model to fit the pressure/flow data in the near-well area (within approximately 2 km). Although the induced seismicity data suggest significant heterogeneity, the daily average wellhead pressure/flow data are insensitive to these features. In the absence of additional constraints, use of more complicated models is unlikely to produce substantial additional benefit for modeling in the near-well area.

Three 1.521.5-m plots were installed and allowed to equilibrate for 2 years before research initiation and were instrumented with 1.52-m zero-tension pan lysimeters installed at 1.5-m depths. Additionally, each plot was instrumented with suction lysimeters, tensiometers, time domain reflectometry (TDR) moisture probes, and thermocouples (to measure soil temperature) at 15-cm depth increments. All plots were enclosed with a raised frame (of 8-cm height) to prevent surface runoff. During the 2-year period before research began, all suction and pan lysimeters were purged monthly and were sampled for fluids immediately prior to atrazine and KBr application to obtain background concentrations. Atrazine illustrated little movement until after a significant rainfall event, which peaked concentrations at depths of about 90 to 135 cm. Both Br super(-) and delta O super(18) moved rapidly through the soil, probably owing to soil porosity and anion exclusion for Br super(-). Concentrations of atrazine exceeding 5.0 mu L super(-1) were observed with depth (90 to 150 cm) after several months. It appears that significant rainfall events were a key factor in the movement of atrazine in the sand, which allowed the chemicals to move to greater depths and thus avoid generally found biodegradation processes.

The aquatic plants of the genus Elodea are potential invaders to Arctic and Subarctic ecosystems circumpolar and at least one species is already established in Alaska, USA. To illustrate the problems of preventing, eradicating, containing, and mitigating aquatic, invasive plants in Arctic and Subarctic ecosystems, we review the invasion dynamics of Elodea and provide recommendations for research and management efforts in Alaska. Foremost, we conclude the remoteness of Arctic and Subarctic systems such as Alaska is no longer a protective attribute against invasions, as transportation pathways now reach throughout these regions. Rather, high costs of operating in remote Arctic and Subarctic systems hinders detection of infestations and limits eradication or mitigation, emphasizing management priorities of prevention and containment of aquatic plant invaders in Alaska and other Arctic and Subarctic systems.

Subsequent Interferometric Synthetic Aperture Radar (InSAR) data analysis revealed an area of surface uplift in the vicinity of the earthquake swarm. To investigate the potential faults that may have caused both the earthquakes and the topographic uplift, we collected similar to 3 km of high-resolution seismic-reflection profiles to image the upper-source region of the swarm. The two profiles reveal a complex deformational pattern within Quaternary alluvial, fluvial, and flood deposits, underlain by Tertiary basalts and basin sediments. At least 100 m of arching on a basalt surface in the upper 500 m is interpreted from both the seismic profiles and magnetic modeling.

AN - 1835413378; 27541712 AB - To evaluate the risks of metal mixture effects to natural stream communities under ecologically relevant conditions, the authors conducted 30-d tests with benthic macroinvertebrates exposed to cadmium (Cd) and zinc (Zn) in experimental streams. The simultaneous exposures were with Cd and Zn singly and with Cd+Zn mixtures at environmentally relevant ratios. The tests produced concentration-response patterns that for individual taxa were interpreted in the same manner as classic single-species toxicity tests and for community metrics such as taxa richness and mayfly (Ephemeroptera) abundance were interpreted in the same manner as with stream survey data. Effect concentrations from the experimental stream exposures were usually 2 to 3 orders of magnitude lower than those from classic single-species tests. Relative to a response addition model, which assumes that the joint toxicity of the mixtures can be predicted from the product of their responses to individual toxicants, the Cd+Zn mixtures generally showed slightly less than additive toxicity. The authors applied a modeling approach called Tox to explore the mixture toxicity results and to relate the experimental stream results to field data. The approach predicts the accumulation of toxicants (hydrogen, Cd, and Zn) on organisms using a 2-pKa bidentate model that defines interactions between dissolved cations and biological receptors (biotic ligands) and relates that accumulation through a logistic equation to biological response. The Tox modeling was able to predict Cd+Zn mixture responses from the single-metal exposures as well as responses from field data. The similarity of response patterns between the 30-d experimental stream tests and field data supports the environmental relevance of testing aquatic insects in experimental streams.

AN - 1835360884; 27539913 AB - Contaminant exposure of tree swallows, Tachycineta bicolor, nesting in 27 Areas of Concern (AOCs) in the Great Lakes basin was assessed from 2010 to 2014 to assist managers and regulators in their assessments of Great Lakes AOCs. Contaminant concentrations in nestlings from AOCs were compared with those in nestlings from nearby non-AOC sites. Polychlorinated biphenyl (PCB) and polybrominated diphenyl ether concentrations in tree swallow nestling carcasses at 30% and 33% of AOCs, respectively, were below the mean concentration for non-AOCs. Polycyclic aromatic hydrocarbon (PAH) concentrations in nestling stomach contents and perfluorinated compound concentrations in nestling plasma at 67% and 64% of AOCs, respectively, were below the mean concentration for non-AOCs. Concentrations of PCBs in nestling carcasses were elevated at some AOCs but modest compared with highly PCB-contaminated sites where reproductive effects have been documented. Concentrations of PAHs in diet were sufficiently elevated at some AOCs to elicit a measurable physiological response. Among AOCs, concentrations of the perfluorinated compound perfluorooctane sulfonate in plasma were the highest on the River Raisin (MI, USA; geometric mean 330 ng/mL) but well below an estimated toxicity reference value (1700 ng/mL). Both PAH and PCB concentrations in nestling stomach contents and PCBs in carcasses were significantly correlated with concentrations in sediment previously reported, thereby reinforcing the utility of tree swallows to assess bioavailability of sediment contamination.

AN - 1793903243; 27092419 AB - Acidic deposition caused by fossil fuel combustion has degraded aquatic and terrestrial ecosystems in North America for over four decades. The only management option other than emissions reductions for combating the effects of acidic deposition has been the application of lime to neutralize acidity after it has been deposited on the landscape. For this reason, liming has been a part of acid rain science from the beginning. However, continued declines in acidic deposition have led to partial recovery of surface water chemistry, and the start of soil recovery. Liming is therefore no longer needed to prevent further damage, so the question becomes whether liming would be useful for accelerating recovery of systems where improvement has lagged. As more is learned about recovering ecosystems, it has become clear that recovery rates vary with watershed characteristics and among ecosystem components. Lakes appear to show the strongest recovery, but recovery in streams is sluggish and recovery of soils appears to be in the early stages. The method in which lime is applied is therefore critical in achieving the goal of accelerated recovery. Application of lime to a watershed provides the advantage of increasing Ca availability and reducing or preventing mobilization of toxic Al, an outcome that is beneficial to both terrestrial and aquatic ecosystems. However, the goal should not be complete neutralization of soil acidity, which is naturally produced. Liming of naturally acidic areas such as wetlands should also be avoided to prevent damage to indigenous species that rely on an acidic environment. Published by Elsevier B.V.

In the data layer a Gaussian elliptical copula having generalized extreme value (GEV) marginals is applied. Spatial dependence in the GEV parameters is captured with a latent spatial regression with spatially varying coefficients. Using a composite likelihood approach, we are able to efficiently incorporate a large precipitation data set, which includes stations with missing data. The model is demonstrated by application to fall precipitation extremes at approximately 2600 stations covering the western United States, -125 degrees E to -100 degrees E longitude and 30 degrees N-50 degrees N latitude. The hierarchical model provides GEV parameters on a 1/8 degrees grid and, consequently, maps of return levels and associated uncertainty. The model results indicate that return levels and their associated uncertainty have a well-defined spatial structure. Maps of return levels provide information about the spatial variations of the risk of extreme precipitation in the western US and is expected to be useful for infrastructure planning.

Multiple sets of records that exhibited such effects were retrieved from tall buildings in Tokyo and Osaka ~350 km and 770 km, respectively, from the epicenter of the 2011 Tohoku earthquake. In California, very few tall buildings have been instrumented. An instrumented 52-story building in downtown Los Angeles recorded seven local and distant earthquakes. Spectral and system identification methods exhibit significant low frequencies of interest (~0.17 Hz, 0.56 Hz, and 1.05 Hz). These frequencies compare well with those computed by transfer functions; however, small variations are observed between the significant low frequencies for each of the seven earthquakes. The torsional and translational frequencies are very close and are coupled. Beating effect is observed in at least two of the seven earthquake data.

Historically, many coastal ecosystems have responded to sea-level fluctuations via horizontal and vertical movement on the landscape. However, anthropogenic activities, including urbanization and the construction of flood-prevention infrastructure, can produce barriers that impede ecosystem migration. Here we show where tidal saline wetlands have the potential to migrate landward along the northern Gulf of Mexico coast, one of the most sea-level rise sensitive and wetland-rich regions of the world. Our findings can be used to identify migration corridors and develop sea-level rise adaptation strategies to help ensure the continued availability of wetland-associated ecosystem goods and services.

With the goal of assisting resource managers and stewards of reefs in setting and measuring progress toward realistic goals for coral-reef conservation and restoration, we examined reef degradation in this region from a geological perspective. The importance of ecosystem services provided by coral reefs-as breakwaters that dissipate wave energy and protect shorelines and as providers of habitat for innumerable species-cannot be overstated. However, the few coral species responsible for reef building in the western Atlantic during the last approximately 1.5 million years are not thriving in the 21st century. These species are highly sensitive to abrupt temperature extremes, prone to disease infection, and have low sexual reproductive potential. Their vulnerability and the low functional redundancy of branching corals have led to the low resilience of western Atlantic reef ecosystems. The decrease in live coral cover over the last 50 years highlights the need for study of relict (senescent) reefs, which, from the perspective of coastline protection and habitat structure, may be just as important to conserve as the living coral veneer. Research is needed to characterize the geological processes of bioerosion, reef cementation, and sediment transport as they relate to modern-day changes in reef elevation. For example, although parrotfish remove nuisance macroalgae, possibly promoting coral recruitment, they will not save Atlantic reefs from geological degradation. In fact, these fish are quickly nibbling away significant quantities of Holocene reef framework. The question of how different biota covering dead reefs affect framework resistance to biological and physical erosion needs to be addressed. Monitoring and managing reefs with respect to physical resilience, in addition to ecological resilience, could optimize the expenditure of resources in conserving Atlantic reefs and the services they provide.Original Abstract: Una Perspectiva Geologica de la Degradacion y Conservacion de los Arrecifes de Coral del Atlantico Oeste Resumen La degradacion continua de los arrecifes de coral en el Atlantico oeste esta resultando en la perdida de las funciones ecologicas y geologicas de los arrecifes. Con el objetivo de asistir a los administradores de los recursos y de los arrecifes en el establecimiento y medida del progreso hacia metas realistas para la conservacion y restauracion de los arrecifes de coral, examinamos la degradacion de los arrecifes en esta region desde una perspectiva geologica. La importancia de los servicios ambientales proporcionados por los arrecifes de coral - como rompeolas que disipan la fuerza de las olas y protegen las lineas de costa y como proveedores de habitat para innumerables especies - no puede ser exagerada. Sin embargo, las pocas especies de coral responsables de la construccion de arrecifes en el Atlantico oeste durante aproximadamente los ultimos 1.5 millones de anos no estan prosperando en el siglo XXI. Estas especies son altamente sensibles a los extremos abruptos de temperatura, propensas a las enfermedades infecciosas y tienen un potencial bajo de reproduccion sexual. Su vulnerabilidad y la baja redundancia funcional de los corales que forman ramas han llevado a la baja resiliencia de los ecosistemas arrecifales del Atlantico oeste. La disminucion en la cobertura de coral vivo en los ultimos 50 anos resalta la necesidad de estudios sobre los arrecifes relictos (senescentes), los cuales desde la perspectiva de la proteccion de la linea costera y la estructura del habitat, pueden ser igual de importantes de conservar que la capa de corales vivientes. Se necesitan investigaciones para caracterizar los procesos geologicos de bioerosion, cementacion de arrecifes y transporte de sedimentos conforme se relacionan a los cambios contemporaneos en la elevacion de los arrecifes. Por ejemplo, aunque el pez loro (familia Scaridae) remueva macroalgas pesadas, lo que posiblemente promueva el reclutamiento de coral, no va a salvar a los arrecifes del Atlantico de la degradacion geologica. De hecho, estos peces estan mordisqueando rapidamente cantidades significativas de marco de trabajo sobre arrecifes del Holoceno. La pregunta de como la biota diferente que cubre los arrecifes muertos afecta al marco de trabajo sobre resistencia a la erosion fisica y biologica necesita ser atendida. El monitoreo y el manejo de los arrecifes con respecto a la resiliencia fisica, ademas de la resiliencia ecologica, podrian optimizar el gasto de los recursos para la conservacion de los arrecifes del Atlantico y los servicios que proporcionan.

We used telemetry data to provide insight into the causes and consequences of local and long-distance movements of multiple age classes of conservation-reliant golden eagles (Aquila chrysaetos) in the foothills and mountains near Tehachapi, California. We estimated size and habitat-related correlates of 324 monthly 95 % home ranges and 317 monthly 50 % core areas for 25 birds moving locally over 2.5 years. We also calculated daily, hourly, and total distances traveled for the five of these birds that engaged in long-distance movements. Mean ( plus or minus SD) monthly home-range size was 253.6 plus or minus 429.4 km super(2) and core-area size was 26.4 plus or minus 49.7 km super(2). Consistent with expectations, space used by pre-adults increased with age and was season-dependent but, unexpectedly, was not sex-dependent. For all ages and sexes, home ranges and core areas were dominated by both forest & woodland and shrubland & grassland habitat types. When moving long distances, eagles traveled up to 1588.4 km (1-way) in a season at highly variable speeds (63.7 plus or minus 69.0 km/day and 5.2 plus or minus 10.4 km/h) that were dependent on time of day. Patterns of long-distance movements by eagles were determined by age, yet these movements had characteristics of more than one previously described movement category (migration, dispersal, etc.). Our results provide a context for differentiating among types of movement behaviors and their population-level consequences and, thus, have implications for management and conservation of golden eagle populations.

A novel method is presented for evaluating assumed relations between K and geologic interpretations for regional-scale groundwater modeling. The approach relies on simultaneous interpretation of multiple aquifer tests using alternative geologic frameworks of variable complexity, where each framework is incorporated as prior information that assumes homogeneous K within each model unit. This approach is tested at Pahute Mesa within the Nevada National Security Site (USA), where observed drawdowns from eight aquifer tests in complex, highly faulted volcanic rocks provide the necessary hydraulic constraints. The investigated volume encompasses 40 mi super(3) (167 km super(3)) where drawdowns traversed major fault structures and were detected more than 2 mi (3.2 km) from pumping wells. Complexity of the five frameworks assessed ranges from an undifferentiated mass of rock with a single unit to 14 distinct geologic units. Results show that only four geologic units can be justified as hydraulically unique for this location. The approach qualitatively evaluates the consistency of hydraulic property estimates within extents of investigation and effects of geologic frameworks on extrapolation. Distributions of transmissivity are similar within the investigated extents irrespective of the geologic framework. In contrast, the extrapolation of hydraulic properties beyond the volume investigated with interfering aquifer tests is strongly affected by the complexity of a given framework. Testing at Pahute Mesa illustrates how this method can be employed to determine the appropriate level of geologic complexity for large-scale groundwater modeling.Original Abstract: Il est difficile d'evaluer la pertinence des structures geologiques utilisees pour extrapoler la conductivite hydraulique (K) jusqu'a des echelles proportionnees avec les donnees hydrodynamiques. Une nouvelle methode est presentee pour evaluer les relations supposees entre K et les interpretations geologiques pour la modelisation hydrogeologique a l'echelle regionale. L'approche repose sur l'interpretation simultanee de multiples essais de pompage en utilisant differentes structures geologiques de complexite variable, ou chaque structure est incorporee en tant qu'information prealable, avec une K homogene dans chaque unite du modele. Cette approche est testee a Pahute Mesa dans le Nevada National Security Site (USA) ou les rabattements observes lors de huit essais de pompage dans des roches volcaniques tres faillees complexes fournissent les contraintes hydrodynamiques necessaires. Le volume investigue 40 mi super(3) (167 km super(3)) au sein desquels les rabattements ont traverse des structures de failles majeures et ont ete detectes a plus de 2 mi (3.2 km) des puits de pompage. La complexite des 5 structures testees va d'une masse indifferenciee de roches, avec une unique unite, jusqu'a 14 unites geologiques distinctes. Les resultats montrent que seules quatre unites geologiques peuvent etre justifiees en tant qu'unite unique hydrauliquement a cet emplacement. L'approche evalue qualitativement la consistance des estimations des proprietes hydrodynamiques dans la zone des investigations et les effets des structures geologiques sur l'extrapolation. Les distributions de transmissivite sont similaires au sein de la zone investiguee quelle que soit la structure geologique. Inversement, l'extrapolation des proprietes hydrodynamiques au-dela du volume investigue avec les essais de pompage par interferences est fortement affectee par la complexite d'une structure geologique donnee. Le test realise a Pahute Mesa illustre comment cette methode peut etre employee pour determiner le niveau approprie de complexite geologique requis pour la modelisation hydrogeologique a grande echelle.

Here, we identify current challenges, provide examples where they are important, and suggest research advances that would benefit environmental flow science. Specifically, environmental flow science would benefit by (1) developing approaches to address streamflow needs in highly modified landscapes where historic flows do not provide reasonable comparisons, (2) integrating water quality needs where interactions are apparent with quantity but not necessarily the proximate factor of the ecological degradation, especially as frequency and magnitudes of inflows to bays and estuaries, (3) providing a better understanding of the ecological needs of native species to offset the often unintended consequences of benefiting non-native species or their impact on flows, (4) improving our understanding of the non-use economic value to balance consumptive economic values, and (5) increasing our understanding of the stakeholder socioeconomic spatial distribution of attitudes and perceptions across the landscape. Environmental flow science is still an emerging interdisciplinary field and by integrating socioeconomic disciplines and developing new frameworks to accommodate our altered landscapes, we should help advance environmental flow science and likely increase successful implementation of flow standards.

Processes operating at different levels of biological organization, with corresponding spatial extents and grains and temporal rates, interact with the evolving configuration of environmental conditions to determine range dynamics. To synthesize understanding of scales and scaling, including relevant biological levels of organization, focusing on the processes that mediate species-environment relationships and the models used to make inferences about species distributions. We review concepts related to the scaling of geographic ranges and implications for the most commonly used analytic methods, using simple simulations to illustrate important issues. Many processes lead to species distributions being dependent on environmental conditions within sites and within a neighborhood. Studies with large extents and fine grains can cut across several levels of biological organization (individual, within-population, and metapopulation processes) complicating interpretation. Many geographic ranges are not in dynamic equilibrium, but common models used for inference assume equilibrium. Interspecific interactions shape species distributions at multiple scales, and arguments for ignoring species interactions also assume equilibrium. There is a need for timely science to inform policy and management decisions; however, we must also strive to provide predictions that best reflect our understanding of ecological systems. Species distributions evolve through time and reflect responses to environmental conditions that are mediated through individual and population processes. Species distribution models that reflect this understanding, and explicitly model dynamics, are likely to give more accurate predictions.

Six subway stations in Seoul were selected for physical environment measurements and a survey of 5282 passengers; these two components were conducted together. The questionnaire addressed thermal, air, light, acoustic and overall comfort. Seoul subway stations had large differences in air temperature in some seasons, and the air temperature in winter was very low. The concentration of particulate matter (PM) and carbon dioxide satisfied the indoor air quality maintenance criteria. Most survey respondents felt 'neutral' about or 'comfortable' with the environment in the subway stations, even in very low temperatures.

AN - 1826733600; 27466973 AB - Carbon dioxide (CO2 ) has shown promise as a tool to control movements of invasive Asian carp, but its effects on native freshwater biota have not been well studied. The authors evaluated lethal and sublethal responses of juvenile fatmucket (Lampsilis siliquoidea) mussels to CO2 at levels (43-269 mg/L, mean concentration) that bracket concentrations effective for deterring carp movement. The 28-d lethal concentration to 50% of the mussels was 87.0 mg/L (95% confidence interval [CI] 78.4-95.9) and at 16-d postexposure, 76.0 mg/L (95% CI 62.9-90.3). A proportional hazards regression model predicted that juveniles could not survive CO2 concentrations >160 mg/L for more than 2 wk or >100 mg/L CO2 for more than 30 d. Mean shell growth was significantly lower for mussels that survived CO2 treatments. Growth during the postexposure period did not differ among treatments, indicating recovery of the mussels. Also, CO2 caused shell pitting and erosion. Behavioral effects of CO2 included movement of mussels to the substrate surface and narcotization at the highest concentrations. Mussels in the 110 mg/L mean CO2 treatment had the most movements in the first 3 d of exposure. If CO2 is infused continuously as a fish deterrent, concentrations <76 mg/L are recommended to prevent juvenile mussel mortality and shell damage. Mussels may survive and recover from brief exposure to higher concentrations. Environ Toxicol Chem 2016;9999:1-11. Published 2016 Wiley Periodicals Inc. on behalf of SETAC.

Regional MODFLOW models commonly use coarse grids over large areas; this coarse spacing precludes model application to local management issues (e.g., surface-water depletion by wells) without recourse to labor-intensive inset models. Implementation of an unstructured formulation within the MODFLOW framework (MODFLOW-USG) allows application of regional models to address local problems. A "semi-structured" approach (uniform lateral spacing within layers, different lateral spacing among layers) was tested using the LMB regional model. The parent 20-layer model with uniform 5000-foot (1524-m) lateral spacing was converted to 4 layers with 500-foot (152-m) spacing in the top glacial (Quaternary) layer, where surface water features are located, overlying coarser resolution layers representing deeper deposits. This semi-structured version of the LMB model reproduces regional flow conditions, whereas the finer resolution in the top layer improves the accuracy of the simulated response of surface water to shallow wells. One application of the semi-structured LMB model is to provide statistical measures of the correlation between modeled inputs and the simulated amount of water that wells derive from local surface water. The relations identified in this paper serve as the basis for metamodels to predict (with uncertainty) surface-water depletion in response to shallow pumping within and potentially beyond the modeled area, see Fienen et al. (2015a). JF - Ground Water AU - Feinstein, Daniel T AU - Fienen, Michael N AU - Reeves, Howard W AU - Langevin, Christian D AD - Wisconsin Water Science Center, USGS, Middleton, WI.

Apart from its distribution and accessibility, BGW usability is a function of the chemical requirements of the intended use, chemical characteristics of the resource, and treatment options to make the resource compatible with the use. Here, we discuss relations between these three chemical factors using national-scale examples and local case studies. In a preliminary compilation of BGW data in the United States, five water types accounted for the major-ion composition of 70% of samples. PHREEQC calculations indicate that 57-77% of samples were oversaturated with respect to barite, calcite, or chalcedony. In the study, 5-14% of samples had concentrations of arsenic, fluoride, nitrate, or uranium that exceeded drinking-water standards. In case studies of the potential use of BGW for drinking water, irrigation, and hydraulic fracturing, PHREEQC simulations of a hypothetical treatment process resembling reverse osmosis (RO) showed that BGW had the potential to form various assemblages of mineral deposits (scale) during treatment that could adversely affect RO membranes. Speciation calculations showed that most boron in the irrigation example occurred as boric acid, which has relatively low removal efficiency by RO. Results of this preliminary study indicate that effective national or regional assessments of BGW resources should include geochemical characterizations that are guided in part by specific use and treatment requirements.

We measured whole blood concentrations of 30 essential and nonessential elements to determine whether any were associated with beak deformities in Northwestern Crows (Corvus caurinus). We tested for differences between 1) adults with versus those without beak deformities and 2) unaffected adults versus juveniles. Crows with beak deformities had slightly higher levels of barium, molybdenum, and vanadium (all P<0.05), but concentrations were generally low and within the range of values reported from other apparently healthy wild birds. Concentrations of several elements, including selenium, were higher in birds without versus birds with beak deformities (all P<0.05), a difference that may be explained in part by compromised foraging ability associated with the deformities. Adult crows had higher concentrations of cadmium, silicon, and zinc than juveniles (all P<0.05), although differences were relatively small and values were similar to those from other wild birds. Our results suggest that neither selenium nor other tested elements are likely to be causing beak deformities in Alaskan crows. We also provide the first data on elemental concentrations in Northwestern Crows. Levels of selenium far exceeded those typically found in passerine birds and were similar to those in marine-associated waterfowl, suggesting that background levels should be interpreted relative to a species' environment.

Live poultry markets are the likely locations of virus exposure to humans. Peridomestic avian species also may play important roles in the transmission and maintenance of H7N9 at live poultry markets. We experimentally challenged wild European Starlings (Sturnus vulgaris) with the novel H7N9 virus and measured virus excretion, clinical signs, and infectious dose. We found that European Starlings can be infected with this virus when inoculated with relatively high doses, and we predict that infected birds excrete sufficient amounts of virus to transmit to other birds, including domestic chickens. Infected European Starlings showed no clinical signs or mortality after infection with H7N9. This abundant peridomestic bird may be a source of the novel H7N9 virus in live poultry markets and may have roles in virus transmission to poultry and humans.

Permafrost thawing has been accelerated by the warming climate and exerts a positive feedback to climate through increasing soil C release to the atmosphere. To evaluate the influence of permafrost on C dynamics, changes in soil temperature profiles should be considered in global C models. This study incorporates a sophisticated soil thermal model (STM) into a dynamic global vegetation model (LPJ-DGVM) to improve simulations of changes in soil temperature profiles from the ground surface to 3 m depth, and its impacts on C pools and fluxes during the 20th and 21st centuries. With cooler simulated soil temperatures during the summer, LPJ-STM estimates approximately 0.4 Pg C yr (super -1) lower present-day heterotrophic respiration but approximately 0.5 Pg C yr (super -1) higher net primary production than the original LPJ model resulting in an additional 0.8 to 1.0 Pg C yr (super -1) being sequestered in circumpolar ecosystems. Under a suite of projected warming scenarios, we show that the increasing active layer thickness results in the mobilization of permafrost C, which contributes to a more rapid increase in heterotrophic respiration in LPJ-STM compared to the stand-alone LPJ model. Except under the extreme warming conditions, increases in plant production due to warming and rising CO (sub 2) , overwhelm the enhanced ecosystem respiration so that both boreal forest and arctic tundra ecosystems remain a net C sink over the 21st century. This study highlights the importance of considering changes in the soil thermal regime when quantifying the C budget in the circumpolar north.

Despite conservation concerns for many species of bats, factors causing mortality in bats have not been reviewed since 1970. Here, we review and qualitatively describe trends in the occurrence and apparent causes of multiple mortality events (MMEs) in bats around the world. 2. We compiled a database of MMEs, defined as cases in which greater than or equal to 10 dead bats were counted or estimated at a specific location within a maximum timescale of a year, and more typically within a few days or a season. We tabulated 1180 MMEs within nine categories. 3. Prior to 2000, intentional killing by humans caused the greatest proportion of MMEs in bats. In North America and Europe, people typically killed bats because they were perceived as nuisances. Intentional killing occurred in South America for vampire bat control, in Asia and Australia for fruit depredation control, and in Africa and Asia for human food. Biotic factors, accidents, and natural abiotic factors were also important historically. Chemical contaminants were confirmed causes of MMEs in North America, Europe, and in islands. Viral and bacterial diseases ranked low as causes of MMEs in bats. 4. Two factors led to a major shift in causes of MMEs in bats at around 2000: the global increase of industrial wind-power facilities and the outbreak of white-nose syndrome in North America. Collisions with wind turbines and white-nose syndrome are now the leading causes of reported MMEs in bats. 5. Collectively, over half of all reported MMEs were of anthropogenic origin. The documented occurrence of MMEs in bats due to abiotic factors such as intense storms, flooding, heat waves, and drought is likely to increase in the future with climate change. Coupled with the chronic threats of roosting and foraging habitat loss, increasing mortality through MMEs is unlikely to be compensated for, given the need for high survival in the dynamics of bat populations.

Patterns and controls of CH sub(4) in fluvial ecosystems remain relatively poorly understood. Furthermore, little is known regarding how major human impacts to fluvial ecosystems may be transforming their role as CH sub(4) producers and emitters. Here, we examine the consequences of two distinct ecosystem changes as a result of human land use: increased nutrient loading (primarily as nitrate), and increased sediment loading and deposition of fine particles in the benthic zone. We did not find support for the hypothesis that enhanced nitrate loading down-regulates methane production via thermodynamic or toxic effects. We did find strong evidence that increased sedimentation and enhanced organic matter content of the benthos lead to greater methane production (diffusive + ebullitive flux) relative to pristine fluvial systems in northern Wisconsin (upper Midwest, USA). Overall, streams in a human-dominated landscape of southern Wisconsin were major regional sources of CH sub(4) to the atmosphere, equivalent to ~20% of dairy cattle emissions, or ~50% of a landfill's annual emissions. We suggest that restoration of the benthic environment (reduced fine deposits) could lead to reduced CH sub(4) emissions, while decreasing nutrient loading is likely to have limited impacts to this ecosystem process.

AN - 1808688749; PQ0003351038 AB - Knowledge of predator diets, including how diets might change through time or differ among predators, provides essential insights into their ecology. Diet estimation therefore remains an active area of research within quantitative ecology. Quantitative fatty acid signature analysis (QFASA) is an increasingly common method of diet estimation. QFASA is based on a data library of prey signatures, which are vectors of proportions summarizing the fatty acid composition of lipids, and diet is estimated as the mixture of prey signatures that most closely approximates a predator's signature. Diets are typically estimated using proportions from a subset of all fatty acids that are known to be solely or largely influenced by diet. Given the subset of fatty acids selected, the current practice is to scale their proportions to sum to 1.0. However, scaling signature proportions has the potential to distort the structural relationships within a prey library and between predators and prey. To investigate that possibility, we compared the practice of scaling proportions with two alternatives and found that the traditional scaling can meaningfully bias diet estimators under some conditions. Two aspects of the prey types that contributed to a predator's diet influenced the magnitude of the bias: the degree to which the sums of unscaled proportions differed among prey types and the identifiability of prey types within the prey library. We caution investigators against the routine scaling of signature proportions in QFASA.

Studies of predation by free-ranging carnivores have particularly benefited from the application of location clustering algorithms to determine when and where predation events occur. These studies have changed our understanding of large carnivore behavior, but the gains have concentrated on obligate carnivores. Facultative carnivores, such as grizzly/brown bears (Ursus arctos), exhibit a variety of behaviors that can lead to the formation of GPS clusters. We combined clustering techniques with field site investigations of grizzly bear GPS locations (n = 732 site investigations; 2004-2011) to produce 174 GPS clusters where documented behavior was partitioned into five classes (large-biomass carcass, small-biomass carcass, old carcass, non-carcass activity, and resting). We used multinomial logistic regression to predict the probability of clusters belonging to each class. Two cross-validation methods-leaving out individual clusters, or leaving out individual bears-showed that correct prediction of bear visitation to large-biomass carcasses was 78-88 %, whereas the false-positive rate was 18-24 %. As a case study, we applied our predictive model to a GPS data set of 266 bear-years in the Greater Yellowstone Ecosystem (2002-2011) and examined trends in carcass visitation during fall hyperphagia (September-October). We identified 1997 spatial GPS clusters, of which 347 were predicted to be large-biomass carcasses. We used the clustered data to develop a carcass visitation index, which varied annually, but more than doubled during the study period. Our study demonstrates the effectiveness and utility of identifying GPS clusters associated with carcass visitation by a facultative carnivore.

Many Mediterranean-climate salt marshes along southern California, USA coast import sediment during El Nino storm events, but sediment fluxes and mechanisms during dry weather are potentially important for marsh stability. We calculated tidal creek sediment fluxes within a highly modified, sediment-starved, 1.5-km super(2) salt marsh (Seal Beach) and a less modified 1-km super(2) marsh (Mugu) with fluvial sediment supply. We measured salt marsh plain suspended sediment concentration and vertical accretion using single stage samplers and marker horizons. At Seal Beach, a 2014 storm yielded 39 and 28 g/s mean sediment fluxes and imported 12,000 and 8800 kg in a western and eastern channel. Western channel storm imports offset 8700 kg exported during 2 months of dry weather, while eastern channel storm imports augmented 9200 kg imported during dry weather. During the storm at Mugu, suspended sediment concentrations on the marsh plain increased by a factor of four; accretion was 1-2 mm near creek levees. An exceptionally high tide sequence yielded 4.4 g/s mean sediment flux, importing 1700 kg: 20 % of Mugu's dry weather fluxes. Overall, low sediment fluxes were observed, suggesting that these salt marshes are geomorphically stable during dry weather conditions. Results suggest storms and high lunar tides may play large roles, importing sediment and maintaining dry weather sediment flux balances for southern California salt marshes. However, under future climate change and sea level rise scenarios, results suggest that balanced sediment fluxes lead to marsh elevational instability based on estimated mineral sediment deficits.

What climatic or water balance variables and antecedent windows of time associated with these variables best relate to the condition of vegetation? Can we develop credible near-term forecasts from climate data that can be used to prepare for future climate change effects on vegetation? Location Semi-arid grasslands in Capitol Reef National Park, Utah, USA. Methods We built vegetation response models by relating the normalized difference vegetation index (NDVI) from MODIS imagery in Mar-Nov 2000-2013 to antecedent climate and water balance variables preceding the monthly NDVI observations. We compared how climate and water balance variables explained vegetation greenness and then used a multi-model ensemble of climate and water balance models to forecast monthly NDVI for three holdout years. Results Water balance variables explained vegetation greenness to a greater degree than climate variables for most growing season months. Seasonally important variables included measures of antecedent water input and storage in spring, switching to indicators of drought, input or use in summer, followed by antecedent moisture availability in autumn. In spite of similar climates, there was evidence the grazed grassland showed a response to drying conditions 1 mo sooner than the ungrazed grassland. Lead times were generally short early in the growing season and antecedent window durations increased from 3 mo early in the growing season to 1 yr or more as the growing season progressed. Forecast accuracy for three holdout years using a multi-model ensemble of climate and water balance variables outperformed forecasts made with a naive NDVI climatology. Conclusions We determined the influence of climate and water balance on vegetation at a fine temporal scale, which presents an opportunity to forecast vegetation response with short lead times. This understanding was obtained through high-frequency vegetation monitoring using remote sensing, which reduces the costs and time necessary for field measurements and can lead to more rapid detection of vegetation changes that could help managers take appropriate actions. Water availability strongly determines productivity in semiarid grasslands but variation in abundance and timing adds complexity.

Hurricane Sandy made landfall during an investigation in Barnegat Bay-Little Egg Harbor estuary that included water quality monitoring, geomorphologic characterization, and numerical modeling; this provided an opportunity to characterize the storm response of the barrier island-estuary system. Barrier island morphologic response was characterized by significant changes in shoreline position, dune elevation, and beach volume; morphologic changes within the estuary were less dramatic with a net gain of only 200,000 m super(3) of sediment. When observed, estuarine deposition was adjacent to the back-barrier shoreline or collocated with maximum estuary depths. Estuarine sedimentologic changes correlated well with bed shear stresses derived from numerically simulated storm conditions, suggesting that change is linked to winnowing from elevated storm-related wave-current interactions rather than deposition. Rapid storm-related changes in estuarine water level, turbidity, and salinity were coincident with minima in island and estuarine widths, which may have influenced the location of two barrier island breaches. Barrier-estuary connectivity, or the transport of sediment from barrier island to estuary, was influenced by barrier island land use and width. Coupled assessments like this one provide critical information about storm-related coastal and estuarine sediment transport that may not be evident from investigations that consider only one component of the coastal system.

Four sites along each river spanned an upstream-to-downstream salinification gradient, from upriver tidal freshwater forested wetland (TFFW), through moderately and highly salt-impacted forested wetlands, to oligohaline marsh downriver. Contemporary deposition rates (sediment, C, N, and P) were greatest in oligohaline marsh and lowest in TFFW along both rivers. Greater rates of deposition in oligohaline and salt-stressed forested wetlands were associated with a shift to greater clay and metal content that is likely associated with a change from low availability of watershed-derived sediment to TFFW and to greater availability of a coastal sediment source to oligohaline wetlands. Long-term accumulation rates along the Waccamaw River had the opposite spatial pattern compared to contemporary deposition, with greater rates in TFFW that declined to oligohaline marsh. Long-term sediment and elemental mass accumulation rates also were 3-9 lower than contemporary deposition rates. In comparison to other studies, sediment and associated nutrient accumulation in TFFW are lower than downriver/estuarine freshwater, oligohaline, and salt marshes, suggesting a reduced capacity for surface sedimentation (short-term) as well as shallow soil processes (long-term sedimentation) to offset sea level rise in TFFW. Nonetheless, their potentially large spatial extent suggests that TFFW have a large impact on the transport and fate of sediment and nutrients in tidal rivers and estuaries.

Shifts in the abundance of native and non-native woody riparian species are an interplay of regulation, life history traits and an array of flow and physical environmental variables. We sought to compare plant densities and per cent cover of several invasive species over two time periods in a paired river study, contrasting three different degrees of regulation along reaches of the Green and Yampa rivers in Colorado and Utah, USA. We censused patches of non-native plants and recorded per cent cover in quadrats along 171river km. The upper Green (10.1patchesha super(-1)) had the highest invasive plant patch density followed by the lower Green (4.4 per ha) and the Yampa (3.3 per ha). Invasive species were present in 23%, 19% and 4% of sample quadrats, and an average of 0.28, 0.22 and 0.04 invasive species detected per square metre was recorded along the upper Green, lower Green and Yampa Rivers, respectively. Most species had significantly (p less than or equal to 0.02) higher percent cover on the upper Green than either or both the lower Green and the Yampa River. Whereas the less regulated river reaches maintain lower densities of invasive species than the most regulated reach, long-term persistence of this pattern is still in question as some species patches showed notable increases on the Yampa and lower Green Rivers from 2002-2005 to 2010-2011. Although invasion is enhanced by flow regulation, life history traits of some species suggest invasion is likely, regardless of flow regulation.

AN - 1797229065; 26801652 AB - Most investigations of the environmental effects of mercury (Hg) have focused on aquatic food webs that include piscivorous fish or wildlife. However, recent investigations have shown that other species, including passerine songbirds, may also be at risk from exposure to methylmercury (MeHg). We quantified Hg concentrations in eggs of two species of songbirds, red-winged blackbirds (Agelaius phoeniceus) and tree swallows (Tachycineta bicolor), nesting in Voyageurs National Park, Minnesota, USA. Geometric mean concentrations of total Hg (THg) were lower in red-winged blackbird eggs [218 and 107 ng/g dry weight (dw) for 2012 and 2013, respectively] than in tree swallow eggs (228 and 300 ng/g dw for 2012 and 2013, respectively), presumably reflecting differences in the trophic positions of these two species. Concentrations of MeHg averaged 98.4 % of THg in red-winged blackbird eggs. Levels of THg observed in this study were well below critical toxicological benchmarks commonly applied to eggs of avian species, suggesting these breeding populations were not adversely affected by exposure to MeHg. In red-winged blackbirds, concentrations of THg in eggs collected in 2012 were twice those in eggs collected in 2013. Hg levels in eggs of both species increased with date of clutch initiation. In red-winged blackbirds, for example, temporal patterns showed that a 3-week delay in clutch initiation increased egg THg by 60 %. These observations indicate that in ovo exposure of wetland birds to MeHg can vary significantly within nesting season as well as between years.

This study represents the first attempt at developing multiple biotic and abiotic MMIs of wetland condition over this large of an area, and is only possible because of the high quality data collected by the NWCA. We chose metrics that distinguished between reference and most disturbed sites, had a signal:noise ratio>2, and were not strongly correlated with other metrics, latitude, or longitude. The vegetation and soil MMIs were the best performing indices, with good separation between reference and most disturbed sites, and included commonly used condition metrics (e.g., pH and P concentration for soil, and percent cover of exotic species for vegetation). The algae MMI was the weakest index, with considerable overlap between reference and most disturbed sites. For areas smaller than our study, algae taxa may be suitable for wetland MMIs. However, in our study area, many algae taxa followed strong latitudinal or longitudinal gradients, and could not be considered for the algae MMI. Small sample size and several metrics with a high signal:noise ratio were the major limitations of the water MMI. We also examined how well landscape (level 1) and rapid assessment (level 2) metrics predicted MMIs using random forest regression. Agricultural land use surrounding wetlands was an important predictor for all four MMIs, although the soil, algae and water MMI models performed best when intensive (level 3) vegetation metrics were also included in the random forest regression models. Based on these results, we recommend wetland assessment programs employ a combination of landscape and rapid assessment monitoring at many sites, along with level 3 monitoring at a subset of sites. We developed these MMIs to evaluate freshwater wetland condition for a long-term monitoring program in Acadia National Park. These MMIs are also applicable to a range of wetland types covering 11 states in the northeastern United States and can be calculated using a downloadable spreadsheet that calculates and rates each MMI using raw metric values.

AN - 1799213897; 27158047 AB - Hurricane Sandy made landfall in Barnegat Bay, October, 29, 2012, damaging shorelines and infrastructure. Estuarine sediment chemistry and toxicity were investigated before and after to evaluate potential environmental health impacts and to establish post-event baseline sediment-quality conditions. Trace element concentrations increased throughout Barnegat Bay up to two orders of magnitude, especially north of Barnegat Inlet, consistent with northward redistribution of silt. Loss of organic compounds, clay, and organic carbon is consistent with sediment winnowing and transport through the inlets and sediment transport modeling results. The number of sites exceeding sediment quality guidance levels for trace elements tripled post-Sandy. Sediment toxicity post-Sandy was mostly unaffected relative to pre-Sandy conditions, but at the site with the greatest relative increase for trace elements, survival rate of the test amphipod decreased (indicating degradation). This study would not have been possible without comprehensive baseline data enabling the evaluation of storm-derived changes in sediment quality. Published by Elsevier Ltd.

AN - 1799213021; 27210565 AB - Some barrier-island dunes damaged or destroyed by Hurricane Sandy's storm surges in October 2012 have been reconstructed using sediments dredged from back bays. These sand-, clay-, and iron sulfide-rich sediments were used to make berm-like cores for the reconstructed dunes, which were then covered by beach sand. In November 2013, we sampled and analyzed partially weathered materials collected from the cores of reconstructed dunes. There are generally low levels of metal toxicants in the reconstructed dune materials. However oxidation of reactive iron sulfides by percolating rainwater produces acid-sulfate pore waters, which evaporate during dry periods to produce efflorescent gypsum and sodium jarosite salts. The results suggest use of sulfidic sediments in dune reconstruction has both drawbacks (e.g., potential to generate acid runoff from dune cores following rainfall, enhanced corrosion of steel bulwarks) and possible benefits (e.g., efflorescent salts may enhance structural integrity).

Low-magnitude aftershocks missing from the network catalog are detected by applying a matched-filter approach to continuous seismic data, with the catalog earthquakes serving as the waveform templates. We measure precise differential arrival times between events, which we use for double-difference event relocation in a 3D seismic velocity model. Most aftershocks are deeper than the mainshock slip, and most occur on the west of the mapped surface rupture. Although the mainshock coseismic and postseismic slip appears to have occurred on the near-vertical, strike-slip West Napa fault, many of the aftershocks occur in a complex zone of secondary faulting. Earthquake locations in the main aftershock zone, near the mainshock hypocenter, delineate multiple dipping secondary faults. Composite focal mechanisms indicate strike-slip and oblique-reverse faulting on the secondary features. The secondary faults were moved toward failure by Coulomb stress changes from the mainshock slip. Clusters of aftershocks north and south of the main aftershock zone exhibit vertical strike-slip faulting more consistent with the West Napa fault. The northern aftershocks correspond to the area of the largest mainshock coseismic slip, whereas the main aftershock zone is adjacent to the fault area that has primarily slipped postseismically. Unlike most creeping faults, the zone of postseismic slip does not appear to contain embedded stick-slip patches that would have produced on-fault aftershocks. The lack of stick-slip patches along this portion of the fault may contribute to the low productivity of the South Napa aftershock sequence. JF - Bulletin of the Seismological Society of America.

The algorithm PPHASEPICKER transforms the signal into a response domain of a single-degree-of-freedom (SDOF) oscillator with viscous damping and then tracks the rate of change of dissipated damping energy to pick P-wave phases. The SDOF oscillator has a short natural period and a correspondingly high resonant frequency, which is higher than most frequencies in a seismic wave. It also has a high damping ratio (60% of critical). At this damping level, the frequency response approaches the Butterworth maximally flat magnitude filter, and phase angles are preserved. The relative input energy imparted to the oscillator by the input signal is converted to elastic strain energy and then dissipated by the damping element as damping energy. The damping energy yields a smooth envelope over time; it is zero in the beginning of the signal, zero or near zero before the P-phase arrival, and builds up rapidly with the P wave. Because the damping energy function changes considerably at the onset of the P wave, it is used as a metric to track and pick the P-phase arrival time. The PPHASEPICKER detects P-phase onset using the histogram method. Its performance is compared with picking techniques using short-term-average to long-term-average ratio, and a picking method that finds the first P-phase arrival time using the Akaike information criterion. A large set of records with various intensities and signal-to-noise ratios is used for testing the PPHASEPICKER, and it is demonstrated that PPHASEPICKER is able to more accurately pick the onset of genuine signals against the background noise and to correctly distinguish between whether the first arrival is a P wave (emergent or impulsive) or whether the signal is from a faulty sensor.Online Material: MATLAB script for P-phase arrival time picking.

AN - 1792538432; 27158049 AB - Mercury (Hg) is considered a contaminant of global concern for coastal environments due to its toxicity, widespread occurrence in sediment, and bioaccumulation in tissue. Coastal New Jersey, USA, is characterized by shallow bays and wetlands that provide critical habitat for wildlife but share space with expanding urban landscapes. This study was designed as an assessment of the magnitude and distribution of Hg in coastal New Jersey sediments and critical species using publicly available data to highlight potential data gaps. Mercury concentrations in estuary sediments can exceed 2μg/g and correlate with concentrations of other metals. Based on existing data, the concentrations of Hg in mussels in southern New Jersey are comparable to those observed in other urbanized Atlantic Coast estuaries. Lack of methylmercury data for sediments, other media, and tissues are data gaps needing to be filled for a clearer understanding of the impacts of Hg inputs to the ecosystem.

In particular, stable-isotope analyses of aragonitic shell material contribute to our understanding of the paleohydrologic history of this ancient lake. Re-examination of molluscan taxonomy in the middle shale and caprock conglomerate (informal) units produces three sphaeriid bivalves (family Sphaeriidae, genus Sphaerium) and two pulmonate gastropod genera (family Planorbidae, genus Gyraulus; and family Lymnaeidae, genus Lymnaea). The middle-shale assemblage, representing quiet-lake deposition, is dominated by pulmonate gastropods; the shell material in all specimens in this unit has been replaced by silica. The caprock conglomerate assemblage, representing redeposition by a debris flow, is dominated by bivalves; specimens within the caprock conglomerate unit are aragonite, interpreted to be biogenic (original). Carbon and oxygen isotope analyses of the aragonite show a strong covariance (all molluscan data: r = 0.83; sphaeriids: r = 0.76) with consistent grouping (delta (super 13) C: 0 ppm to -5.5 ppm, delta (super 18) O: +2 ppm to -5 ppm) from all families. This result indicates that ancient Lake Florissant was "closed" and that evaporation had a stronger effect on isotopic values than precipitation, for the duration of the sampled interval. This finding is in agreement with our current understanding of how the sediments of the Florissant Formation were deposited within a lake that formed because of a paleoriver being dammed by debris flows.

Few data exist on electric barrier parameters that minimize these impacts and on how body size affects susceptibility, especially to nontarget fish species. The goal of this study was to determine electric barrier voltage and pulse-width settings that inhibit passage of larger bodied rainbow trout Oncorhynchus mykiss(215-410 mm fork length) while allowing passage of smaller bodied juvenile rainbow trout (52-126 mm) in a static laboratory setting. We exposed rainbow trout to 30-Hz pulsed-direct current voltage gradients (0.00-0.45 V cm super(-1)) and pulse widths (0.0-0.7 ms) and recorded their movement, injury incidence, and mortality. No settings tested allowed all juveniles to pass while impeding all adult passage. Juvenile and adult rainbow trout avoided the barrier at higher pulse widths, and fewer rainbow trout passed the barrier at 0.7-ms pulse width compared to 0.1 ms and when the barrier was turned off. We found no effect of voltage gradient on fish passage. No mortality occurred, and we observed external bruising in 5 (7%) juvenile rainbow trout and 15 (21%) adult rainbow trout. This study may aid managers in selecting barrier settings that allow for increased juvenile passage.

To achieve this integration, some LCCs have adopted the approach of providing their partners with better scientific information in an effort to facilitate more efficient and coordinated conservation decisions. Taking this approach has led many LCCs to begin funding research to provide the information for improved decision making. To ensure that funding goes to research projects with the highest likelihood of leading to more integrated broad-scale conservation, some LCCs have also developed approaches for prioritizing which information needs will be of most benefit to their partnerships. We describe two case studies in which decision-analytic tools were used to quantitatively assess the relative importance of information for decisions made by partners in the Plains and Prairie Potholes LCC. The results of the case studies point toward a few valuable lessons in terms of using these tools with LCCs. Decision-analytic tools tend to help shift focus away from research-oriented discussions and toward discussions about how information is used in making better decisions. However, many technical experts do not have enough knowledge about decision-making contexts to fully inform the latter type of discussion. When assessed in the right decision context, however, decision analyses can point out where uncertainties actually affect optimal decisions and where they do not. This helps technical experts understand that not all research is valuable in improving decision making. Perhaps most important, our results suggest that decision-analytic tools may be more useful for LCCs as a way of developing integrated objectives for coordinating partner decisions across the landscape, rather than simply ranking research priorities.

Diet studies of rainbow trout and brown trout in Glen and Grand canyons indicate that these species eat native fish, but impacts are difficult to assess because predation vulnerability is highly variable depending on the physical conditions under which the predation interactions take place. We conducted laboratory experiments to evaluate how short-term predation vulnerability of juvenile humpback chub changes in response to changes in turbidity. In overnight laboratory trials, we exposed hatchery-reared juvenile humpback chub and bonytail Gila elegans(a surrogate for humpback chub) to adult rainbow trout and brown trout at turbidities ranging from 0 to 1,000 formazin nephlometric units. We found that turbidity as low as 25 formazin nephlometric units significantly reduced predation vulnerability of bonytail to rainbow trout and led to a 36% mean increase in survival (24-60%, 95% CI) compared to trials conducted in clear water. Predation vulnerability of bonytail to brown trout at 25 formazin nephlometric units also decreased with increasing turbidity and resulted in a 25% increase in survival on average (17-32%, 95% CI). Understanding the effects of predation by trout on endangered humpback chub is important when evaluating management options aimed at preservation of native fishes in Grand Canyon National Park. This research suggests that relatively small changes in turbidity may be sufficient to alter predation dynamics of trout on humpback chub in the mainstem Colorado River and that turbidity manipulation may warrant further investigation as a fisheries management tool.

We evaluate use of sediment dredged from a navigation channel to establish a feeder beach adjacent to a bulkhead as a solution for addressing erosion of landforms and habitats on sandy estuarine shores. The objectives are to determine how beach volume, position and shape within and downdrift of the fill area change and whether the volumes supplied by dredging match sediment losses caused by human actions. The fill was placed along a 75 m length of shoreline adjacent to a marina in Great South Bay at Fire Island, New York, USA. Changes in beach shape and volume were determined from topographic surveys conducted before and after fill and at half year intervals for 18 months. The quantity of fill was 1747 m (super 3) . Maximum shoreline advance due to fill emplacement was 20.7 m. The maximum volume placed at any transect was 28.6 m (super 3) m (super - 1) of shoreline length. Erosion of the fill occurred rapidly, with landward migration of a conspicuous scarp. The edge of the upland 18 months after the fill was placed was up to 4.6 m farther landward than prior to the fill. Movement of sediment alongshore downdrift of the fill occurred as wave-like pulses, extending the active foreshore bayward, causing accretion of the inner low tide terrace, burying saltmarsh peat outcrops on the foreshore and creating a higher and wider overwash platform over portions of the saltmarshes. Landforms downdrift of the fill area underwent successive stages including erosion (pre-nourishment), accretion, stability (with throughput of sediment) and then erosion. Beach nourishment compensates for human-induced sediment losses. The volume of sediment added from maintenance dredging can slow the rate of erosion but may not prevent long-term shoreline retreat. Restoration and maintenance of coastal landforms and habitats to specific target states at a given location is difficult, but augmenting longshore sediment inputs can allow those locations to undergo cycles of erosion and accretion, creating a variety of landforms and habitats where only erosional forms existed previously. Alternatively, nourishment could occur more frequently and in smaller volumes to reduce fluctuations in accretion-erosion cycles. Abstract Copyright (2016) Elsevier, B.V.

This is both the first report of tracks from this unit in the Dinosaur Ridge area and the first report of deinonychosaurian tracks from Colorado. It is also only the third report of this track type from North America. The rarity of tracks from the Albian-aged, Plainview Sandstone (Dakota Group Sequence 2) contrasts with their abundance in the upper (Cenomanian) part of the overlying South Platte Formation (Dakota Group Sequence 3), which has yielded more than 120 sites mostly in Colorado, giving rise to the "Dinosaur Freeway" concept. As no deinonychosaurid tracks are known from the sequence 3 part of the South Platte Formation, despite the large vertebrate and invertebrate ichnological database available, it is evident that the sparse vertebrate ichnofauna from the Plainview Member (Sequence 2) is inherently different. This striking difference in both track abundance and track type reflects differences in both age and depositional environment. Based on the Albian age, and track type, the Plainview tracks invite comparison with the ichnofaunas of the Cedar Mountain Formation and not with those well-known from the upper part of the South Platte Formation known as the Dinosaur Freeway.

In the western US, prairie dog populations experience nearly 100% mortality during plague outbreaks, suggesting that multiple transmission pathways combine to amplify plague dynamics. Several alternate pathways in addition to flea vectors have been proposed, such as transmission via direct contact with bodily fluids or inhalation of infectious droplets, consumption of carcasses, and environmental sources of plague bacteria, such as contaminated soil. However, evidence supporting the ability of these proposed alternate pathways to trigger large-scale epizootics remains elusive. Here we present a short review of potential plague transmission pathways and use an ordinary differential equation model to assess the contribution of each pathway to resulting plague dynamics in black-tailed prairie dogs (Cynomys ludovicianus) and their fleas (Oropsylla hirsuta). Using our model, we found little evidence to suggest that soil contamination was capable of producing plague epizootics in prairie dogs. However, in the absence of flea transmission, direct transmission, i.e., contact with bodily fluids or inhalation of infectious droplets, could produce enzootic dynamics, and transmission via contact with or consumption of carcasses could produce epizootics. This suggests that these pathways warrant further investigation.

Climate warming and related drivers of soil thermal change are expected to modify the distribution of permafrost, leading to changing hydrologic conditions, including alterations in soil moisture, connectivity of inland waters, streamflow seasonality, and the partitioning of water stored above and below ground. The field of permafrost hydrology is undergoing rapid advancement with respect to multiscale observations, subsurface characterization, modeling, and integration with other disciplines. However, gaining predictive capability of the many interrelated consequences of climate change is a persistent challenge due to several factors. Observations of hydrologic change have been causally linked to permafrost thaw, but applications of process-based models needed to support and enhance the transferability of empirical linkages have often been restricted to generalized representations. Limitations stem from inadequate baseline permafrost and unfrozen hydrogeologic characterization, lack of historical data, and simplifications in structure and process representation needed to counter the high computational demands of cryohydrogeologic simulations. Further, due in part to the large degree of subsurface heterogeneity of permafrost landscapes and the nonuniformity in thaw patterns and rates, associations between various modes of permafrost thaw and hydrologic change are not readily scalable; even trajectories of change can differ. This review highlights promising advances in characterization and modeling of permafrost regions and presents ongoing research challenges toward projecting hydrologic and ecologic consequences of permafrost thaw at time and spatial scales that are useful to managers and researchers.

Here, we assess the frequency of collapses among 68 exotic bird populations established in Hawaii, Puerto Rico, Los Angeles and Miami. Following other published definitions, we define a 'collapse' as a decline in abundance of greater than or equal to 90 % within less than or equal to 10 years that lasts for at least 3 years. We show that 44 of the 68 exotic bird populations have exhibited declines at some point within their time series. Sixteen of the populations declined sufficiently to be defined as collapsed. It took on average 3.8 plus or minus 1.8 years for populations to decline into a collapsed state, and this state persisted on average for 7.1 plus or minus 6.3 years across (collapsed) populations. We compared the severity and duration of declines across all 44 declining populations according to taxonomic Order and geographic region. Neither variable explained substantial variation in the metrics of collapse. Our results indicate that severe, rapid, and persistent population declines may be common among exotic populations. We suggest that incorporating the probability and persistence of collapses into management decisions can inform efforts to enact control or eradication measures. We also suggest that applying our approach to other taxa and locations is crucial for improving our understanding of when and where collapses are likely to occur.

Three ecological models have been proposed to explain patterns of these two life history types. In this study, we test these three models using data from California chaparral. We take an innovative approach to testing these models by not testing community or landscape patterns, but instead, investigating vegetation structure characteristic of four pairs of resprouting and (non-resprouting) obligate seeding subspecies of Arctostaphylos (Ericaceae), a dominant and diverse shrub genus in California chaparral. Data were analyzed for percentage bare ground, elevation, annual precipitation, number of fires, and time between fires and were compared independently for each subspecies pair. Results were consistently supportive of the gap-dependent model suggesting that obligate seeders are favored when post-disturbance gaps are large. Results were inconclusive or contrary to expectations for both of the other two models.

Known as "tree islands", these ecogeomorphic features can be found in few other low gradient, nutrient limited freshwater wetlands. In the last few decades, however, a large percentage of tree islands have either shrank or disappeared in apparent response to altered water depths and other stressors associated with human impacts on the Everglades. Because the processes determining the formation and spatial organization of tree islands remain poorly understood, it is still unclear what controls the sensitivity of these landscapes to altered conditions. We hypothesize that positive feedbacks between woody plants and soil accretion are crucial to emergence and decline of tree islands. Likewise, positive feedbacks between phosphorus (P) accumulation and trees explain the P enrichment commonly observed in tree island soils. Here, we develop a spatially-explicit model of tree island formation and evolution, which accounts for these positive feedbacks (facilitation) as well as for long range competition and fire dynamics. It is found that tree island patterns form within a range of parameter values consistent with field data. Simulated impacts of reduced water levels, increased intensity of drought, and increased frequency of dry season/soil consuming fires on these feedback mechanisms result in the decline and disappearance of tree islands on the landscape.

The map is solely an illustration of the withdrawal magnitudes, spatially centered on wells-it is not capture zones or source areas contributing recharge to wells. Common practice is to scale the size (area) of withdrawal well symbols proportional to pumping rate. Symbols are drawn large enough to be visible, but not so large that they overlap excessively. In contrast to such graphics-based symbol sizes, the proposed method uses a depth-rate index (length per time) to visualize the well withdrawal rates by volumetrically consistent areas, called "footprints". The area of each individual well's footprint is the withdrawal rate divided by the depth-rate index. For example, the groundwater recharge rate could be used as a depth-rate index to show how large withdrawals are relative to that recharge. To account for the interference of nearby wells, composite footprints are computed by iterative nearest-neighbor distribution of excess withdrawals on a computational and display grid having uniform square cells. The map shows circular footprints at individual isolated wells and merged footprint areas where wells' individual footprints overlap. Examples are presented for depth-rate indexes corresponding to recharge, to spatially variable stream baseflow (normalized by basin area), and to the average rate of water-table decline (scaled by specific yield). These depth-rate indexes are water-resource metrics, and the footprints visualize the magnitude of withdrawals relative to these metrics.Original Abstract: Une methode simple est proposee pour visualiser l'amplitude des prelevements d'eau souterraine par forages se rapportant aux valeurs de la ressource en eau definies par l'utilisateur. La carte est uniquement une illustration des quantites prelevees, spatialement centree sur les forages - il ne s'agit pas de zones d'appel ou d'aires d'alimentation des forages. La demarche habituelle consiste a dimensionner la taille (surface) des symboles des points de prelevements proportionnellement au taux de pompage. Les symboles sont representes de taille suffisamment grande pour etre visibles, sans pour autant qu'il y ait des recouvrements des symboles entre eux de maniere excessive. Contrairement a ce type de symboles graphiques bases sur la taille, la methode proposee utilise un indice de taux de prelevement par rapport a la profondeur (longueur par unite de temps) pour visualiser les taux de prelevement des forages selon des surfaces coherentes du point de vue volumetrique, appelees "empreintes". La surface de chaque empreinte individuelle d'un forage correspond aux taux de prelevement divise par l'indice taux de prelevement-profondeur. Par exemple, le taux de recharge des eaux souterraines pourrait etre utilise comme indice taux de prelevement-profondeur pour montrer l'importance des prelevements en comparaison de la recharge. Pour tenir compte des interferences entre des forages proches, des empreintes composites sont calculees selon une distribution iterative du plus proche voisin des prelevements excedentaires sur une grille a mailles carrees uniformes. La carte montre des empreintes circulaires pour les forages isoles et des empreintes fusionnees pour les empreintes de forages qui se recouvrent. Des exemples sont presentes pour des indices taux de prelevements-profondeur correspondant a la recharge, au debit de base spatialise du cours d'eau (normalise par la surface du bassin), et au taux moyen de baisse du niveau piezometrique (mise a l'echelle a l'aide du debit specifique). Ces indices taux de prelevements-profondeur constituent des valeurs de la ressource en eau, et les empreintes permettent de visualiser l'amplitude des prelevements se rapportant a ces valeurs.

This is especially true in situations where the abundance of one species may inhibit that of another, such as the intensively-farmed landscape of the Prairie Pothole Region (PPR) of the central United States, where waterfowl production is largely constrained by mesocarnivore nest predation. We used a hierarchical Bayesian approach to relate the distribution of various land-cover types to the relative abundances of four mesocarnivores in the PPR: coyote Canis latrans, raccoon Procyon lotor, red fox Vulpes vulpes, and striped skunk Mephitis mephitis. We developed models for each species at multiple spatial resolutions (41.4 km super(2), 10.4 km super(2), and 2.6 km super(2)) to address different ecological and management-related questions. Model results for each species were similar irrespective of resolution. We found that the amount of row-crop agriculture was nearly ubiquitous in our best models, exhibiting a positive relationship with relative abundance for each species. The amount of native grassland land-cover was positively associated with coyote and raccoon relative abundance, but generally absent from models for red fox and skunk. Red fox and skunk were positively associated with each other, suggesting potential niche overlap. We found no evidence that coyote abundance limited that of other mesocarnivore species, as might be expected under a hypothesis of mesopredator release. The relationships between relative abundance and land-cover types were similar across spatial resolutions. Our results indicated that mesocarnivores in the PPR are most likely to occur in portions of the landscape with large amounts of agricultural land-cover. Further, our results indicated that track-survey data can be used in a hierarchical framework to gain inferences regarding spatial patterns in animal relative abundance.

Trend assessment typically entails fitting a regression to a time series of abundances to estimate population trajectory. However, changes in abundance estimates from year-to-year across time are due to both true variation in population size (process variation) and variation due to imperfect sampling and model fit. State-space models are a relatively new method that can be used to partition the error components and quantify trends based only on process variation. We compare a state-space modelling approach with a more traditional linear regression approach to assess trends in uncorrected raw counts and detection-corrected abundance estimates of forest birds at Hakalau Forest National Wildlife Refuge, Hawai'i. Most species demonstrated similar trends using either method. In general, evidence for trends using state-space models was less strong than for linear regression, as measured by estimates of precision. However, while the state-space models may sacrifice precision, the expectation is that these estimates provide a better representation of the real world biological processes of interest because they are partitioning process variation (environmental and demographic variation) and observation variation (sampling and model variation). The state-space approach also provides annual estimates of abundance which can be used by managers to set conservation strategies, and can be linked to factors that vary by year, such as climate, to better understand processes that drive population trends.

AN - 1790960370; PQ0003134266 AB - Small headwater fens at high elevations exist in the dry climatic regime of western Colorado, despite increasing demands for water development since the 1800's. Fens on Grand Mesa have accumulated plant material as peat for thousands of years due to cold temperatures and consistently saturated soils. The peatlands maintain unique plant communities, wildlife habitat, biodiversity, and carbon storage. We located and differentiated 88 fens from 15 wet meadows and 2 marshes on Grand Mesa. Field work included determining vegetation, soils, moisture regimes, and impacts from human activities. All fens were groundwater-supported systems that occurred in depressions and slopes within sedimentary landslide and volcanic glacial till landscapes. Fens occupied 400 ha or less than 1 % of the 46,845 ha research area and ranged in size from 1 to 46 ha. Peat water pH in undisturbed sites ranged from 4.3 to 7.1. Most fens had plant communities dominated by sedges (Carex) with an understory of brown mosses. Variation in vegetation was controlled by stand wetness, water table level, organic C, conductivity (EC), and temperature degree C. Fen soils ranged from 13.6 to 44.1 % organic C with a mean of 30.3 %. Species diversity in fens was restricted by cold short growing seasons, stressful anaerobic conditions, and disturbance. Multivariate analysis was used to analyze relationships between vegetation, environmental, and impact variables. Stand wetness, water table level, OC, electrical conductivity (EC), and temperature were used to analyze vegetation variance in undisturbed fens, wet meadows, and marshes. Vegetation composition in impacted fens was influenced by flooding, sedimentation, stand wetness, water table level, OC, EC, and temperature. Hydrologically modified fens supported 58 plant species compared to 101 species in undisturbed fens. Analysis of historical 1936-2007 aerial photographs and condition scalars helped quantify impacts of human activities in fens as well as vegetation changes. Fourteen fens had evidence of peat subsidence, from organic soil collapse, blocks of peat in the margins, soil instability, and differences in surface peat height between the fen soil surface and the annually flooded soil surface. Of 374 ha of fens in the Grand Mesa study area, 294 ha (79 %) have been impacted by human activities such as ditching, drainage, flooding, or vehicular rutting. Many fens had little restoration potential due to severe hydrological and peat mass impacts, water rights, or the cost of restoration.

Portions of the historical range, however, have been recolonized and even expanded due to planting of conservation reserve program (CRP) fields that provide favorable vegetation structure for Lesser Prairie-Chickens. The source population(s) feeding the range expansion is unknown, yet has resulted in overlap between Lesser and Greater Prairie-Chickens (T. cupido) increasing the potential for hybridization. Our objectives were to characterize connectivity and genetic diversity among populations, identify source population(s) of recent range expansion, and examine hybridization with the Greater Prairie-Chicken. We analyzed 640 samples from across the range using 13 microsatellites. We identified three to four populations corresponding largely to ecoregions. The Shinnery Oak Prairie and Sand Sagebrush Prairie represented genetically distinct populations (F sub(ST) > 0.034 and F sub(ST) > 0.023 respectively). The Shortgrass/CRP Mosaic and Mixed Grass ecoregions appeared admixed (F sub(ST) = 0.009). Genetic diversity was similar among ecoregions and N sub(e) ranged from 142 (95 % CI 99-236) for the Shortgrass/CRP Mosaic to 296 (95 % CI 233-396) in the Mixed Grass Prairie. No recent migration was detected among ecoregions, except asymmetric dispersal from both the Mixed Grass Prairie and to a lesser extent the Sand Sagebrush Prairie north into adjacent Shortgrass/CRP Mosaic (m = 0.207, 95 % CI 0.116-0.298, m = 0.097, 95 % CI 0.010-0.183, respectively). Indices investigating potential hybridization in the Shortgrass/CRP Mosaic revealed that six of the 13 individuals with hybrid phenotypes were significantly admixed suggesting hybridization. Continued monitoring of diversity within and among ecoregions is warranted as are actions promoting genetic connectivity and range expansion.

We conducted a systematic review to describe how temporal variation in temperature and streamflow influences trout ecology in freshwater ecosystems. Few studies (n = 42) have quantified relationships between temperature or streamflow and trout demography, growth, or phenology, and nearly all estimates (96 %) were for Salvelinus fontinalis and Salmo trutta. Only seven studies used temporal data to quantify climate-driven changes in trout ecology. Results from these studies were beset with limitations that prohibited quantitatively rigorous meta-analysis, a concerning inadequacy given major investment in trout conservation and management worldwide. Nevertheless, consistent patterns emerged from our synthesis, particularly a positive effect of summer streamflow on trout demography and growth; 64 % of estimates were positive and significant across studies, age classes, species, and locations, highlighting that climate-induced changes in hydrology may have numerous consequences for trout. To a lesser degree, summer and fall temperatures were negatively related to population demography (51 and 53 % of estimates, respectively), but temperature was rarely related to growth. To address limitations and uncertainties, we recommend: (1) systematically improving data collection, description, and sharing; (2) appropriately integrating climate impacts with other intrinsic and extrinsic drivers over the entire lifecycle; (3) describing indirect consequences of climate change; and (4) acknowledging and describing intrinsic resiliency.

Along with lake drawdown, these processes often boost aquatic chemical concentrations, potentially impacting trophic dynamics. In particular, elevated chemical levels may impact primary productivity, which may in turn influence populations of primary and secondary consumers. We examined trophic dynamics of 18 shrinking lakes of the Yukon Flats, Alaska, that had experienced pronounced increases in nutrient (>200 % total nitrogen, >100 % total phosphorus) and ion concentrations (>100 % for four major ions combined) from 1985-1989 to 2010-2012, versus 37 stable lakes with relatively little chemical change over the same period. We found that phytoplankton stocks, as indexed by chlorophyll concentrations, remained unchanged in both shrinking and stable lakes from the 1980s to 2010s. Moving up the trophic ladder, we found significant changes in invertebrate abundance across decades, including decreased abundance of five of six groups examined. However, these decadal losses in invertebrate abundance were not limited to shrinking lakes, occurring in lakes with stable surface areas as well. At the top of the food web, we observed that probabilities of lake occupancy for ten waterbird species, including adults and chicks, remained unchanged from the period 1985-1989 to 2010-2012. Overall, our study lakes displayed a high degree of resilience to multi-trophic cascades caused by rising chemical concentrations. This resilience was likely due to their naturally high fertility, such that further nutrient inputs had little impact on waters already near peak production.

AN - 1790930530; PQ0003094883 AB - As the recognition of the importance of biological diversity in biological conservation grows, an ongoing challenge is to develop metrics that can be used for effective conservation and management. The ecological integrity assessment has been proposed as such a metric. It is held by some to measure species composition, diversity, and habitat quality, as well as ecosystem structure, composition, and function. The methodology relies on proxy variables that include data on landscape characteristics such as patch size, abiotic factors such as hydrology, and some features of vegetation structure and composition. We suggest that the measure is flawed on four levels. First, its putative representation of general ecological form and function, and its lack of specific detail about how it actually represents those attributes, leaves the metric without the focus needed to be useful for measuring ecological features on the ground and testing associated hypotheses and predictions. Second, the proxy variables used to represent biological diversity, such as habitat (vegetation) metrics and vascular plant species diversity, are not empirically correlated with diversity of a range of taxa or of other components of the biota. Third, like other ecological indices that integrate many distinct features, the ecological integrity index is subject to the loss of information in its condensation of multi-dimensional variability into a one-dimensional index, and it may be subject to systematic bias from the conversion of raw data into categorical scores. Fourth, the sampling protocols are at risk of sampling bias, observer bias, and measurement error, any of which can confound the estimation of conservation value. In terms of biological diversity, the methodology produces an unreliable estimate of the number of vascular plant species and their relative percentages of occurrence, and an absence of any protocols for taxa other than plants. For these reasons we believe that ecological integrity assessment is currently of limited value as a measure of site-specific biological diversity and its change over time. A considerable amount of investigation is needed in order to have confidence in the results of an ecological integrity assessment, especially if it is to be used for regulatory purposes. We suggest further refinements and discuss alternative measures of biological diversity that provide reliable metrics for assessing change. A thoughtful choice among measures can help to identify the most appropriate assessment for conservation decisions.

AN - 1789037185; 27170357 AB - Insecticide use in urban areas results in the detection of these compounds in streams following stormwater runoff at concentrations likely to cause toxicity for stream invertebrates. In this 2013 study, stormwater runoff and streambed sediments were analyzed for 91 pesticides dissolved in water and 118 pesticides on sediment. Detections included 33 pesticides, including insecticides, fungicides, herbicides, degradates, and a synergist. Patterns in pesticide occurrence reveal transport of dissolved and sediment-bound pesticides, including pyrethroids, from upland areas through stormwater outfalls to receiving streams. Nearly all streams contained at least one insecticide at levels exceeding an aquatic-life benchmark, most often for bifenthrin and (or) fipronil. Multiple U.S. EPA benchmark or criterion exceedances occurred in 40 % of urban streams sampled. Bed sediment concentrations of bifenthrin were highly correlated (p < 0.001) with benthic invertebrate assemblages. Non-insects and tolerant invertebrates such as amphipods, flatworms, nematodes, and oligochaetes dominated streams with relatively high concentrations of bifenthrin in bed sediments, whereas insects, sensitive invertebrates, and mayflies were much more abundant at sites with no or low bifenthrin concentrations. The abundance of sensitive invertebrates, % EPT, and select mayfly taxa were strongly negatively correlated with organic-carbon normalized bifenthrin concentrations in streambed sediments. Our findings from western Clackamas County, Oregon (USA), expand upon previous research demonstrating the transport of pesticides from urban landscapes and linking impaired benthic invertebrate assemblages in urban streams with exposure to pyrethroid insecticides.

We examined whether the spatial distribution of the endangered Alasmidonta heterodon in Flat Brook, a tributary of the upper Delaware River, was constrained by water chemistry (i.e., calcium availability), bed mobility, or both. Alasmidonta heterodon populations were bracketed between upstream reaches that were under-saturated with respect to aragonite and downstream reaches that were saturated for aragonite during summer baseflow but had steep channels with high bed mobility. Variability in bed mobility and water chemistry along the length of Flat Brook create a "habitat window" for A. heterodon defined by bed stability (mobility index less than or equal to 1) and aragonite saturation (saturation index greater than or equal to 1). We suggest the species may exist in a narrow biogeochemical window that is seasonally near saturation. Alasmidonta heterodon populations may be susceptible to climate change or anthropogenic disturbances that increase discharge, decrease groundwater inflow or chemistry, and thus affect either bed mobility or aragonite saturation. Identifying the biogeochemical microhabitats and requirements of individual mussel species and incorporating this knowledge into management decisions should enhance the conservation and restoration of endangered mussel species.

AN - 1777986074; 26950618 AB - Organic compounds used in agriculture, industry, and households make their way into surface waters through runoff, leaking septic-conveyance systems, regulated and unregulated discharges, and combined sewer overflows, among other sources. Concentrations of these organic waste compounds (OWCs) in some Great Lakes tributaries indicate a high potential for adverse impacts on aquatic organisms. During 2010-13, 709 water samples were collected at 57 tributaries, together representing approximately 41% of the total inflow to the lakes. Samples were collected during runoff and low-flow conditions and analyzed for 69 OWCs, including herbicides, insecticides, polycyclic aromatic hydrocarbons, plasticizers, antioxidants, detergent metabolites, fire retardants, non-prescription human drugs, flavors/fragrances, and dyes. Urban-related land cover characteristics were the most important explanatory variables of concentrations of many OWCs. Compared to samples from nonurban watersheds (15% urban land cover) had nearly four times the number of detected compounds and four times the total sample concentration, on average. Concentration differences between runoff and low-flow conditions were not observed, but seasonal differences were observed in atrazine, metolachlor, DEET, and HHCB concentrations. Water quality benchmarks for individual OWCs were exceeded at 20 sites, and at 7 sites benchmarks were exceeded by a factor of 10 or more. The compounds with the most frequent water quality benchmark exceedances were the PAHs benzo[a]pyrene, pyrene, fluoranthene, and anthracene, the detergent metabolite 4-nonylphenol, and the herbicide atrazine. Computed estradiol equivalency quotients (EEQs) using only nonsteroidal endocrine-active compounds indicated medium to high risk of estrogenic effects (intersex or vitellogenin induction) at 10 sites. EEQs at 3 sites were comparable to values reported in effluent. This multifaceted study is the largest, most comprehensive assessment of the occurrence and potential effects of OWCs in the Great Lakes Basin to date. Published by Elsevier B.V.

Intense early cratering affected Mars by melting and fracturing its crust, draping large areas in impact ejecta, generating regional-scale hydrothermal systems, and increasing atmospheric pressure (and thereby, temperature) to periodically re-start an otherwise moribund hydrological cycle. Post primary-accretionary bombardment scenarios that shaped early Mars can be imagined in two ways: either as a simple exponential decay with an approximately 100 Myr half-life, or as a "sawtooth" timeline characterized by both faster-than-exponential decay from primary accretion and relatively lower total delivered mass. Indications are that a late bombardment spike was superposed on an otherwise broadly monotonic decline subsequent to primary accretion, of which two types are investigated: a classical "Late Heavy Bombardment" (LHB) peak of impactors centered at ca. 3900 Ma that lasted 100 Myr, and a protracted bombardment typified by a sudden increase in impactor flux at ca. 4100-4200 Ma with a correspondingly longer decay time (< or =400 Myr). Numerical models for each of the four bombardment scenarios cited above show that the martian crust mostly escaped exogenic melting from bombardment. We find that depending on the chosen scenario, other physical effects of impacts were more important than melt generation. Model output shows that between 10 and 100% of the Noachian surface was covered by impact craters and blanketed in resultant (hot) ejecta. If early Mars was generally arid and cold, impact-induced heating punctuated this surface state by intermittently destabilizing the near-subsurface cryosphere to generate regional-scale hydrothermal systems. Rather than being deleterious to the proclivity of Noachian Mars to host an emergent biosphere, this intense early impact environment instead enhanced the volume and duration of its surface/subsurface geophysical habitable zone.

Recognizing that each climate index has underlying band-limited components that contribute most of the energy of the signals, we first pursue a wavelet decomposition of the signals to identify and reconstruct these features from annually resolved historical data and proxy based paleoreconstructions of each climate index covering the period from 1650 to 2012. A K-Nearest Neighbor block bootstrap approach is then developed to simulate the total signal of each of these climate index series while preserving its time-frequency structure and marginal distributions. Finally, given the simulated climate signal time series, a K-Nearest Neighbor bootstrap is used to simulate annual streamflow series conditional on the joint state space defined by the simulated climate index for each year. We demonstrate this method by applying it to simulation of streamflow at Lees Ferry gauge on the Colorado River using indices of two large scale climate forcings: Pacific Decadal Oscillation (PDO) and Atlantic Multi-decadal Oscillation (AMO), which are known to modulate the Colorado River Basin (CRB) hydrology at multidecadal time scales. Skill in stochastic simulation of multidecadal projections of flow using this approach is demonstrated. Abstract Copyright (2016), . American Geophysical Union. All Rights Reserved.

A detailed reconstruction of this time interval is critical for understanding the nature of biotic and environmental changes preceding the end-Cretaceous Mass Extinction event and for deciphering the likely extinction mechanism (i.e., bolide impact versus volcanism). Eight sections encompassing the K/Pg succession across the Mississippi Embayment were analyzed using biostratigraphic sampling of ammonites, dinoflagellates, and nannofossils. An upper Maastrichtian ammonite zonation is proposed as follows, from oldest to youngest: Discoscaphites conradi Zone, D. minardi Zone, and D. iris Zone. Our study documents that the ammonite zonation established in the Atlantic Coastal Plain (ACP) extends to the GCP. This zonation is integrated with nannofossil and dinoflagellate biostratigraphy to provide a framework to more accurately determine the age relationships in this region. We demonstrate that ammonites and dinoflagellates are more reliable stratigraphic indicators in this area than nannofossils because age-diagnostic nannofossils are not consistently present within the upper Maastrichtian in the GCP. This biostratigraphic framework has the potential to become a useful tool for correlation of strata both within the GCP and between the GCP, Western Interior, and ACP. The presence of the uppermost Maastrichtian ammonite D. iris, calcareous nannofossil Micula prinsii, and dinoflagellates Palynodinium grallator and Disphaerogena carposphaeropsis suggests that the K/Pg succession in the GCP is nearly complete. Consequently, the GCP is an excellent setting for investigating fine scale temporal changes across the K/Pg boundary and ultimately elucidating the mechanisms causing extinction.

This paper examines efforts by the U.S. National Park Service to change long-term policies in Yellowstone and Yosemite national parks. We argue that, to be successful, the agency and pro-change allies must expand the sphere of conflict to engage the support of the broader American public through positive framing, supportive science, compelling economic arguments, consistent goals, and the commitment of other institutional actors. We show that the agency is capable of creating these conditions, as in the reintroduction of wolves to Yellowstone, but we argue that this is not always the outcome, as in reducing automobile congestion in Yosemite Valley.

Almost all 50 States within the United States (excluding Delaware and Rhode Island) have karst areas, with sinkhole damage highest in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania. A conservative estimate of losses to all types of ground subsidence was $125 million per year in 1997. This estimate may now be low, as review of cost reports from the last 15 years indicates that the cost of karst collapses in the United States averages more than $300 million per year. Knowing when a catastrophic event will occur is not possible; however, understanding where such occurrences are likely is possible. The US Geological Survey has developed and maintains national-scale maps of karst areas and areas prone to sinkhole formation. Several States provide additional resources for their citizens; Alabama, Colorado, Florida, Indiana, Iowa, Kentucky, Minnesota, Missouri, Ohio, and Pennsylvania maintain databases of sinkholes or karst features, with Florida, Kentucky, Missouri, and Ohio providing sinkhole reporting mechanisms for the public.Original Abstract: L'affaissement des terrains du a l'effondrement de dolines est un phenomene frequent dans les regions ou les roches solubles a l'eau sont presentes, telles que les roches carbonatees et evaporitiques, typiques des terrains karstiques.

Une estimation prudente des pertes associees a tous types d'affaissement du sol etait de 125 millions de $ par annee en 1997.

This agriculture relies heavily on surface-water diversions and groundwater pumpage to meet irrigation water demand. Because the valley is semi-arid and surface-water availability varies substantially, agriculture relies heavily on local groundwater. In the southern two thirds of the valley, the San Joaquin Valley, historic and recent groundwater pumpage has caused significant and extensive drawdowns, aquifer-system compaction and subsidence. During recent drought periods (2007-2009 and 2012-present), groundwater pumping has increased owing to a combination of decreased surface-water availability and land-use changes. Declining groundwater levels, approaching or surpassing historical low levels, have caused accelerated and renewed compaction and subsidence that likely is mostly permanent. The subsidence has caused operational, maintenance, and construction-design problems for water-delivery and flood-control canals in the San Joaquin Valley. Planning for the effects of continued subsidence in the area is important for water agencies. As land use, managed aquifer recharge, and surface-water availability continue to vary, long-term groundwater-level and subsidence monitoring and modelling are critical to understanding the dynamics of historical and continued groundwater use resulting in additional water-level and groundwater storage declines, and associated subsidence. Modeling tools such as the Central Valley Hydrologic Model, can be used in the evaluation of management strategies to mitigate adverse impacts due to subsidence while also optimizing water availability. This knowledge will be critical for successful implementation of recent legislation aimed toward sustainable groundwater use.Original Abstract: La Vallee Centrale de Californie (Etats-Unis d'Amerique) couvre environ 52,000 km super(2) et constitue l'une des regions agricoles les plus productives du monde. Cette agriculture depend fortement d'apports d'eaux de surface canalisees et de pompages d'eaux souterraines, pour repondre a la demande en eau d'irrigation. Parce que la vallee est semi-aride et que la ressource en eau de surface est tres variable, l'agriculture depend beaucoup des eaux souterraines locales. Dans les deux-tiers sud de la vallee, la Vallee de San Joaquin, les prelevements d'eaux souterraines historiques et recents ont provoque des rabattements importants et etendus, ainsi qu'une compaction du systeme aquifere et une subsidence des terrains. Au cours des periodes de secheresse recentes (2007-2009 et 2012 jusqu'a maintenant), les prelevements d'eaux souterraines ont augmente en raison d'une reduction de la ressource en eaux de surface et de changements dans l'occupation des sols. La baisse des niveaux piezometriques, approchant ou depassant les niveaux historiques bas, ont engendre une acceleration et un accroissement de la compaction et de la subsidence, qui sont probablement irreversibles. La subsidence a provoque des problemes operationnels, de maintenance et de conception pour l'adduction d'eau et pour les canaux, dans la Vallee de San Joaquin. La prevision des effets d'une poursuite de la subsidence dans la region est importante pour les agences de l'eau. Tandis que l'occupation des sols, la recharge des aquiferes, et la ressource en eaux de surface continuent a evoluer, le suivi du niveau des eaux souterraines a long-terme, la surveillance de la subsidence et la modelisation sont cruciaux pour comprendre les dynamiques des usages historiques et a venir des eaux souterraines resultant de la baisse conjointe des niveaux d'eau et des stocks d'eaux souterraines, ainsi que la subsidence associee. Les outils de modelisation, tel que le modele hydrologique de la Vallee Centrale, peuvent etre utilises dans l'evaluation des strategies de gestion pour attenuer les impacts negatifs dus a la subsidence, en optimisant la ressource en eau disponible. Cette connaissance sera cruciale pour une mise en oeuvre reussie de la legislation recente qui a pour objectif une utilisation durable des eaux souterraines.

We show that the inclusion or exclusion of the eggshell can influence egg contaminant concentrations, and we provide estimates of egg density (both with and without the eggshell) and egg-shape coefficients (used to estimate egg volume from egg morphometrics) for American avocet (Recurvirostra americana), black-necked stilt (Himantopus mexicanus), and Forster's tern (Sterna forsteri). Egg densities (g/cm super(3)) estimated for whole eggs (1.056 plus or minus 0.003) were higher than egg densities estimated for egg contents (1.024 plus or minus 0.001), and were 1.059 plus or minus 0.001 and 1.025 plus or minus 0.001 for avocets, 1.056 plus or minus 0.001 and 1.023 plus or minus 0.001 for stilts, and 1.053 plus or minus 0.002 and 1.025 plus or minus 0.002 for terns. The egg-shape coefficients for egg volume (K v ) and egg mass (K w ) also differed depending on whether the eggshell was included (K v = 0.491 plus or minus 0.001; K w = 0.518 plus or minus 0.001) or excluded (K v = 0.493 plus or minus 0.001; K w = 0.505 plus or minus 0.001), and varied among species. Although egg contaminant concentrations are rarely meant to include the eggshell, we show that the typical inclusion of the eggshell in egg density and egg volume estimates results in egg contaminant concentrations being underestimated by 6-13 %. Our results demonstrate that the inclusion of the eggshell significantly influences estimates of egg density, egg volume, and fresh egg mass, which leads to egg contaminant concentrations that are biased low. We suggest that egg contaminant concentrations be calculated on a fresh wet weight basis using only internal egg-content densities, volumes, and masses appropriate for the species. For the three waterbirds in our study, these corrected coefficients are 1.024 plus or minus 0.001 for egg density, 0.493 plus or minus 0.001 for K v , and 0.505 plus or minus 0.001 for K w .

Trend analyses indicate that springtime regional mean PM (sub 2.5) dust concentrations have increased from 1995 to 2014, especially in March (5.4% yr (super -1) , p < 0.01). This increase reflects an earlier onset of the spring dust season across the Southwest by 1 to 2 weeks over the 20 year time period. March dust concentrations were strongly correlated with the Pacific Decadal Oscillation index (r = -0.65, p < 0.01), which was mostly in its negative phase from 2007 to 2014, during which the region was drier, windier, and less vegetated. The positive spring trend and its association with large-scale climate variability have several important implications for visibility, particulate matter, health effects, and the hydrologic cycle in the region.

AN - 1769622936; 26851756 AB - Sediment-toxicity benchmarks are needed to interpret the biological significance of currently used pesticides detected in whole sediments. Two types of freshwater sediment benchmarks for pesticides were developed using spiked-sediment bioassay (SSB) data from the literature. These benchmarks can be used to interpret sediment-toxicity data or to assess the potential toxicity of pesticides in whole sediment. The Likely Effect Benchmark (LEB) defines a pesticide concentration in whole sediment above which there is a high probability of adverse effects on benthic invertebrates, and the Threshold Effect Benchmark (TEB) defines a concentration below which adverse effects are unlikely. For compounds without available SSBs, benchmarks were estimated using equilibrium partitioning (EqP). When a sediment sample contains a pesticide mixture, benchmark quotients can be summed for all detected pesticides to produce an indicator of potential toxicity for that mixture. Benchmarks were developed for 48 pesticide compounds using SSB data and 81 compounds using the EqP approach. In an example application, data for pesticides measured in sediment from 197 streams across the United States were evaluated using these benchmarks, and compared to measured toxicity from whole-sediment toxicity tests conducted with the amphipod Hyalella azteca (28-d exposures) and the midge Chironomus dilutus (10-d exposures). Amphipod survival, weight, and biomass were significantly and inversely related to summed benchmark quotients, whereas midge survival, weight, and biomass showed no relationship to benchmarks. Samples with LEB exceedances were rare (n=3), but all were toxic to amphipods (i.e., significantly different from control). Significant toxicity to amphipods was observed for 72% of samples exceeding one or more TEBs, compared to 18% of samples below all TEBs. Factors affecting toxicity below TEBs may include the presence of contaminants other than pesticides, physical/chemical characteristics of sediment, and uncertainty in TEB values. Additional evaluations of benchmarks in relation to sediment chemistry and toxicity are ongoing. Published by Elsevier B.V.

In only a few streams are brook trout abundant in lower stream reaches that are accessible to adult Pacific salmonids migrating from the lake. Consequently, because of the rarity of native brook trout populations in these lower stream reaches it is important to understand how they use stream habitat in sympatry with juvenile Pacific salmonids which are now naturalized in several Lake Ontario tributaries. In this study, we examined the seasonal (spring, summer, and fall) habitat use of brook trout and juvenile steelhead (Oncorhynchus mykiss) in Hart Brook, a tributary of eastern Lake Ontario. We found interspecific, intraspecific, and seasonal variation in habitat use. Subyearling steelhead were associated with faster water velocities than subyearling brook trout and, overall, had the least habitat similarity to the other salmonid groups examined. Overyearling brook trout and yearling steelhead exhibited the greatest degree of habitat selection and habitat selection by all four salmonid groups was greatest in summer. The availability of pool habitat for overyearling salmonids may pose the largest impediment to these species in Hart Brook.

To estimate how widespread exposure to the parasite is in nene (Hawaiian Geese, Branta sandvicensis), we did a serologic survey for T. gondii antibody and genetically characterized parasite DNA from the tissues of dead birds that had confirmed infections by immunohistochemistry. Of 94 geese sampled, prevalence on the island of Kauai, Maui, and Molokai was 21% (n=42), 23% (n=31), and 48% (n=21), respectively. Two new T. gondii genotypes (ToxoDB #261 and #262) were identified by PCR-restriction fragment length polymorphism from four geese, and these appeared segregated geographically. Exposure to T. gondii in wild nene is widespread and, while the parasite is not a major cause of death, it could have sublethal or behavioral effects. How to translate such information to implement effective ways to manage feral cats in Hawaii poses challenges.

The role of avian species inhabiting sagebrush in the amplification of WNV in arid and semiarid regions of the North America is unknown. We conducted an experimental WNV challenge study in Vesper Sparrows (Pooecetes gramineus), a species common to sagebrush and grassland habitats found throughout much of North America. We found Vesper Sparrows to be moderately susceptible to WNV, developing viremia considered sufficient to transmit WNV to feeding mosquitoes, but the majority of birds were capable of surviving infection and developing a humoral immune response to the WNV nonstructural 1 and envelope proteins. Despite clearance of viremia, after 6 mo, WNV was detected molecularly in three birds and cultured from one bird. Surviving Vesper Sparrows were resistant to reinfection 6 mo after the initial challenge. Vesper sparrows could play a role in the amplification of WNV in sagebrush habitat and other areas of their range, but rapid clearance of WNV may limit their importance as competent amplification hosts of WNV.

Although the virus has been noted as an apparent incidental finding in several species of ducks, little is known about the prevalence of exposure or the outcome of infection with WNV in wild ducks in North America. From 2004-06, we collected sera from 1,406 wild-caught American Wigeon (Anas americana), Mallard (Anas platyrhynchos), and Northern Pintail (Anas acuta) ducks at national wildlife refuges (NWRs) in North Dakota and Wood Ducks (Aix sponsa) at NWRs in South Carolina and Tennessee. We measured the prevalence of previous exposure to WNV in these ducks by measuring WNV antibodies and evaluated variation in exposure among species, age, and year. Additionally, we evaluated the performance of a commercial antibody to wild bird immunoglobulin in duck species that varied in their phylogenetic relatedness to the bird species the antibody was directed against. As determined by a screening immunoassay and a confirmatory plaque reduction neutralization assay, the prevalence of WNV antibody was 10%. In light of experimental studies that show ducks to be relatively resistant to mortality caused by WNV, the antibody prevalence we detected suggests that wild ducks may be less-frequently exposed to WNV than expected for birds inhabiting wetlands where they may acquire infection from mosquitoes.

Eutrophication is particularly focused in the shallow western basin. The western basin of Lake Erie is hydrodynamically similar to a large estuary, with riverine inputs from the Detroit and Maumee Rivers mixing together and creating gradients in chemical and physical conditions. In a common consumer approach, individuals of a single species are raised under similar conditions until placed in the field across environmental gradients of interest. After some period of exposure, the response of that common consumer is measured to provide an index of spatial variation in conditions. We found secondary production was highest within the Maumee river mouth and lowest in the open waters of the lake. The results suggest that growth of secondary consumers and the availability of important fatty acids in the western basin are centered on the Maumee river mouth.

Beyond basic needs, research indicates quality interaction is associated with positive health and well-being benefits, particularly for older adults. In this, design supporting social relationships plays an essential role. This study's purpose was to identify New Urbanist neighborhood and social space design attributes supporting older residents' physiological and social needs. This case study used keyword-in-context analysis with focus group interview data to identify domains supporting social interaction for residents aging in place including: location factors, social factors, design factors, and programmatic factors.

S. National Park Service. The site is known for a historic cabin, Slaven's Roadhouse, which was constructed on a deep, stratified river terrace. This landform was previously found to contain archaeological materials that are at least 4000 years old. The geophysical study, which included a combination of ground-penetrating radar, magnetic, electromagnetic, and electrical methods, revealed details of the depositional context and potential archaeological features of likely middle Holocene origin, the age of which is supported by radiocarbon dates of charcoal found in association with some of the detected anomalies.

Towards an Accurate Lexicon for Climate Change Adaptation AN - 1776661947; PQ0002819293 AB - Climate change adaptation is a rapidly evolving field in conservation biology and includes a range of strategies from resisting to actively directing change on the landscape. The term 'climate change resilience,' frequently used to characterize adaptation strategies, deserves closer scrutiny because it is ambiguous, often misunderstood, and difficult to apply consistently across disciplines and spatial and temporal scales to support conservation efforts. Current definitions of resilience encompass all aspects of adaptation from resisting and absorbing change to reorganizing and transforming in response to climate change. However, many stakeholders are unfamiliar with this spectrum of definitions and assume the more common meaning of returning to a previous state after a disturbance. Climate change, however, is unrelenting and intensifying, characterized by both directional shifts in baseline conditions and increasing variability in extreme events. This ongoing change means that scientific understanding and management responses must develop concurrently, iteratively, and collaboratively, in a science-management partnership. Divergent concepts of climate change resilience impede cross-jurisdictional adaptation efforts and complicate use of adaptive management frameworks. Climate change adaptation practitioners require clear terminology to articulate management strategies and the inherent tradeoffs involved in adaptation. Language that distinguishes among strategies that seek to resist change, accommodate change, and direct change (i.e., persistence, autonomous change, and directed change) is prerequisite to clear communication about climate change adaptation goals and management intentions in conservation areas.

Mercury (Hg) is a particularly widespread contaminant that biomagnifies in amphibians and can cause a suite of deleterious effects. However, monitoring contaminant exposure in amphibian tissues may conflict with conservation goals if lethal take is required. Thus, there is a need to develop non-lethal tissue sampling techniques to quantify contaminant exposure in amphibians. Some minimally invasive sampling techniques, such as toe-clipping, are common in population-genetic research, but it is unclear if these methods can adequately characterize contaminant exposure. We examined the relationships between mercury (Hg) concentrations in non-lethally sampled tissues and paired whole-bodies in five amphibian species. Specifically, we examined the utility of three different tail-clip sections from four salamander species and toe-clips from one anuran species. Both tail and toe-clips accurately predicted whole-body THg concentrations, but the relationships differed among species and the specific tail-clip section or toe that was used. Tail-clips comprised of the distal 0-2 cm segment performed the best across all salamander species, explaining between 82 and 92 % of the variation in paired whole-body THg concentrations. Toe-clips were less effective predictors of frog THg concentrations, but THg concentrations in outer rear toes accounted for up to 79 % of the variability in frog whole-body THg concentrations. These findings suggest non-lethal sampling of tails and toes has potential applications for monitoring contaminant exposure and risk in amphibians, but care must be taken to ensure consistent collection and interpretation of samples.

Sites were selected from a pool of naturally similar sub-basins (eco-region, basin size, and geology) of the Mobile River basin (MRB), using an index of urban intensity derived from infrastructure, socioeconomic, and land-use data. This urban land-use gradient (ULUG) is a multimetric indicator of urban intensity, ranging from 0 (background) to 100 (intense urbanization). Campostoma sp. have been used previously as indicators of stream health and are common species found in all sites within the MRB. Endpoints used to determine the effects of urban land-use on the largescale stoneroller included total glutathione, histology, hepatic apoptosis, condition factor and external lesions. Liver glutathione levels were positively associated with increasing urban land-use (r super(2) = 0.94). Histopathological examination determined that some abnormalities and lesions were correlated with the ULUG and generally increased in prevalence or severity with increasing urbanization. Liver macrophage aggregates were positively correlated to the ULUG. The occurrence of nucleosomal ladders (indicating apoptotic cell death) did not correspond with urban intensity in a linear fashion. Apoptosis, as well as prevalence and severity of a myxozoan parasite, appeared to have a hormetic dose-response relationship. The majority of the biomarkers suggested fish health was compromised in areas where the ULUG greater than or equal to 36.

Introduction, overview, and key messages from a SETAC-SER workshop. AN - 1776629719; 26414121 AB - A workshop on Restoration of Impaired Ecosystems was held in Jackson, Wyoming, in June 2014. Experts from Australia, Canada, Mexico, the United Kingdom, and the United States in ecotoxicology, restoration, and related fields from both the Society of Environmental Toxicology and Chemistry and the Society for Ecological Restoration convened to advance the practice of restoring ecosystems that have been contaminated or impaired from industrial activities. The overall goal of this workshop was to provide a forum for ecotoxicologists and restoration ecologists to define the best scientific practices to achieve ecological restoration while addressing contaminant concerns. To meet this goal, participants addressed 5 areas: 1) links between ecological risk assessment and ecological restoration, 2) restoration goals, 3) restoration design, 4) monitoring for restoration effectiveness and 5) recognizing opportunities and challenges. Definitions are provided to establish a common language across the varied disciplines. The current practice for addressing restoration of impaired ecosystems tends to be done sequentially to remediate contaminants, then to restore ecological structure and function. A better approach would anticipate or plan for restoration throughout the process. By bringing goals to the forefront, we may avoid intrusive remediation activities that close off options for the desired restoration. Participants realized that perceived limitations in the site assessment process hinder consideration of restoration goals; contaminant presence will influence restoration goal choices; social, economic, and cultural concerns can factor into goal setting; restoration options and design should be considered early during site assessment and management; restoration of both structure and function is encouraged; creative solutions can overcome limitations; a regional focus is imperative; monitoring must occur throughout the restoration process; and reciprocal transfer of knowledge is needed among theorists, practitioners, and stakeholders and among varied disciplines. © 2015 The Authors.

The National Atmospheric Deposition Program (NADP) has been measuring Nr deposition in this region for over 35 years. Here we explore the relationships among NADP-measured Nr deposition, nitrogen stable isotopes (delta (super 15) N) in lake sediments, and the response of algal communities in 28 lakes situated in national parks of the western Great Lakes region of the U.S. We find that 36% of the lakes preserve a sediment delta (super 15) N record that is statistically correlated with some form of Nr deposition (total dissolved inorganic N, nitrate, or ammonium). Furthermore, measured long-term (since 1982) nitrogen biogeochemistry and inferred critical nitrogen loads suggest that watershed nitrogen retention and climate strongly affect whether sediment delta (super 15) N is related to Nr deposition in lake sediment records. Measurements of algal change over the last approximately 150 years suggest that Nr deposition, in-lake nutrient cycling, and watershed inputs are important factors affecting diatom community composition, in addition to direct climatic effects on lake physical limnology. The findings suggest that bulk sediment delta (super 15) N does reflect Nr deposition in some instances. In addition, this study highlights the interactive effects of Nr deposition and climate variability. Abstract Copyright (2016), . American Geophysical Union. All Rights Reserved.

However, unknowns remain regarding how temperature and moisture interact to regulate dryland soil respiration (R s), while 'islands of fertility' in drylands create spatially heterogeneous R s . At a site in southeastern Utah, USA we added or removed litter (0-650 % of control) in plots associated with either shrubs or biological soil crust-dominated interspaces between vascular plants. We measured R s , soil temperature (T sub(s)), and water content ([thetas]) repeatedly from October 2013 to November 2014. R s was highest following rain in late summer at T sub(s) ~30 degree C, and lowest mid-summer at T sub(s) > 40 degree C, resulting in apparent negative temperature sensitivity of R s at high temperatures, and positive temperature sensitivity at low-moderate temperatures. We used Bayesian statistical methods to compare models capturing a range of hypothesized relationships between T sub(s), [thetas], and R s . The best model indicates that apparent negative temperature sensitivity of R s at high T sub(s) reflects the control of water content, not high temperatures. Modeled Q sub(10) ranged from 2.7 to 1.4 between 5 and 45 degree C. Litter addition had no effect on Q sub(10) or reference respiration (R ref = R s at 20 degree C and optimum [thetas]) beneath shrubs, and little effect on R ref in interspaces, yet R ref was 1.5 times higher beneath shrubs than in interspaces. Altogether, these results suggest reduced R s often observed at high T sub(s) in drylands is dominated by the control of [thetas], and, on shorter-timescales, variable litter inputs exert minimal control over R s .

AN - 1768562423; 26687501 AB - Pomacea maculata (formerly P. insularum), an apple snail native to South America, was discovered in Louisiana in 2008. These snails strip vegetation, reproduce at tremendous rates, and have reduced rice production and caused ecosystem changes in Asia. In this pilot study snails were exposed to two molluscicides, a tea (Camellia sinensis) seed derivative (TSD) or niclosamide monohydrate (Pestanal(®), 2',5-dichloro-4'-nitrosalicylanilide, CAS #73360-56-2). Mortality was recorded after exposure to high or low concentrations (0.03 and 0.015 g/L for TSD, 1.3 and 0.13 mg/L for niclosamide). The TSD induced 100 % mortality at both concentrations. Niclosamide caused 100 % and 17 % mortality at high and low concentrations respectively. These molluscicides were also tested on potential biocontrol agents, the red swamp crayfish (Procambarus clarkii) and redear sunfish (Lepomis microlophus). No crayfish mortalities occurred at either concentration for either chemical, but sunfish experienced 100 % mortality with TSD (0.03 g/L), and 21 % mortality with niclosamide (0.13 mg/L).

In estuarine research, hydrodynamic and ecological models have moved along parallel tracks with regard to complexity, refinement, computational power, and incorporation of uncertainty. Coupled hydrodynamic-ecological models have been used to assess ecosystem processes and interactions, simulate future scenarios, and evaluate remedial actions in response to eutrophication, habitat loss, and freshwater diversion. The need to couple hydrodynamic and ecological models to address research and management questions is clear because dynamic feedbacks between biotic and physical processes are critical interactions within ecosystems. In this review, we present historical and modern perspectives on estuarine hydrodynamic and ecological modeling, consider model limitations, and address aspects of model linkage, skill assessment, and complexity. We discuss the balance between spatial and temporal resolution and present examples using different spatiotemporal scales. Finally, we recommend future lines of inquiry, approaches to balance complexity and uncertainty, and model transparency and utility. It is idealistic to think we can pursue a "theory of everything" for estuarine models, but recent advances suggest that models for both scientific investigations and management applications will continue to improve in terms of realism, precision, and accuracy.

Recent Source to Sink (S2S) studies of the Waipaoa Sedimentary System (WSS), New Zealand, are synthesized herein to provide a holistic perspective of the processes that generate, transport and preserve sedimentary strata and organic carbon on the Waipaoa margin in the late Quaternary. Rapid uplift associated with subduction processes and weak sedimentary units have conspired to generate rapid rates of incision and erosion in the Waipaoa catchment since the Last Glacial Maximum (LGM). We show that although much of the sediment exported offshore during this time interval originated from valley excavation, a substantial portion emanated from hillslopes, mostly through deep-seated landslide and earthflow processes that were vigorous during periods of rapid fluvial incision just prior to the Pleistocene-Holocene transition. Lacustrine sediments deposited in naturally-dammed 7-ky-old Lake Tutira provide a record of Holocene environmental controls on upper catchment sedimentation in the WSS, with 1400 storms identified. Storm frequency is modulated by the waxing and waning of atmospheric teleconnections between the tropics and Antarctica. Furthermore, clear long-term changes in sediment yield are evident from the Lake Tutira record following human settlement as conversion to pasture is accompanied by a 3-fold increase in the long-term lake sediment accumulation rate. Whereas there is ample evidence that Waipaoa River flood deposits are routinely deposited offshore in the sheltered confines of Poverty Bay, over the longer term, waves and currents subsequently resuspend and transport these deposits both landward (sandy fraction) and seaward (finer fraction). Thus, the timing of sediment supply to areas of net sediment accumulation is more often driven by wave events that are not associated with river flooding. Therefore, we conclude that asynchronicity of river-sediment delivery and of wave resuspension in most instances precludes the direct preservation of flood events in the stratigraphic record of the Waipaoa Shelf. Over the longer term, the sediment package preserved on the shelf and slope since the LGM can be explained in large measure by sequence-stratigraphic models forced by varying sea level and ongoing tectonic deformation of the margin. As sea level rose, sediment supply to the slope was reduced by about a factor of 5 due to shelf trapping. Despite this reduction, turbidites are found at similar frequency throughout the LGM-Present, as the dominant trigger appears to be subduction earthquakes, with large ones having a return interval of about 200 + or - 100 years. Sediment-budget exercises that consider both modern (river discharge versus centennial accumulation rates) and post-LGM (terrestrial production versus offshore isopachs) mass balances indicate that about half of the total sediment production from the Waipaoa escapes the study area. Moreover, a coupled sediment transport-hydrodynamic model and observations of textural trends on the shelf indicate that a large fraction of the sediment is carried outside the study area along the shelf to the northeast by the river plume or by combined current/wave activity. Therefore, we conclude that the WSS is an open system with sediment escape from the present day through the LGM.

The coupled effect of bivalve grazing at the sediment-water interface and sinking of phytoplankton cells to that bottom filtration zone could influence the relative biomass of sinking (diatoms) and non-sinking phytoplankton. Simulations with a pseudo-2D numerical model showed that benthic filter feeding can interact with sinking to alter diatom:non-diatom ratios. Cases with the smallest proportion of diatom biomass were those with the fastest sinking speeds and strongest bivalve grazing rates. Hydrodynamics modulated the coupled sinking-grazing influence on phytoplankton communities. For example, in simulations with persistent stratification, the non-sinking forms accumulated in the surface layer away from bottom grazers while the sinking forms dropped out of the surface layer toward bottom grazers. Tidal-scale stratification also influenced vertical gradients of the two groups in opposite ways. The model was applied to Suisun Bay, a low-salinity habitat of the San Francisco Bay system that was transformed by the introduction of the exotic clam Potamocorbula amurensis. Simulation results for this Bay were similar to (but more muted than) those for generic habitats, indicating that P. amurensis grazing could have caused a disproportionate loss of diatoms after its introduction. Our model simulations suggest bivalve grazing affects both phytoplankton biomass and community composition in shallow waters. We view these results as hypotheses to be tested with experiments and more complex modeling approaches.

Here we use geodetic observations including GPS and InSAR to characterize the Loma Prieta earthquake postseismic displacements from 1989 to 2013. Pre-earthquake deformation rates are constrained by nearly 20 yr of USGS trilateration measurements and removed from the postseismic measurements prior to the analysis. We observe GPS horizontal displacements at mean rates of 1-4 mm/yr toward Loma Prieta Mountain until 2000, and approximately 2 mm/yr surface subsidence of the northern Santa Cruz Mountains between 1992 and 2002 shown by InSAR, which is not associated with the seasonal and longer-term hydrological deformation in the adjoining Santa Clara Valley. Previous work indicates afterslip dominated in the early (1989-1994) postseismic period, so we focus on modeling the postseismic viscoelastic relaxation constrained by the geodetic observations after 1994. The best fitting model shows an elastic 19-km-thick upper crust above an 11-km-thick viscoelastic lower crust with viscosity of approximately 6 X 10 (super 18) Pas, underlain by a viscous upper mantle with viscosity between 3 X 10 (super 18) and 2 X 10 (super 19) Pas. The millimeter-scale postseismic deformation does not resolve the viscosity in the different layers very well, and the lower-crustal relaxation may be localized in a narrow shear zone. However, the inferred lithospheric rheology is consistent with previous estimates based on post-1906 San Francisco earthquake measurements along the San Andreas fault system. The viscoelastic relaxation may also contribute to the enduring increase of aseismic slip and repeating earthquake activity on the San Andreas fault near San Juan Bautista, which continued for at least a decade after the Loma Prieta event.

The 2014-2015 Pahoa lava flow crisis, however, was unique in terms of its societal impact and volcanological characteristics. Despite low effusion rates, a long-lived lava flow whose extent reached 20 km (the longest at Kilauea Volcano in the past several hundred years) was poised for months to impact thousands of people, although direct impacts were ultimately minor (thus far). Careful observation of the flow reaffirmed and expanded knowledge of the processes associated with pahoehoe emplacement, including the direct correlation between summit pressurization and flow advance, the influence of existing geologic structures on flow pathways, and the possible relationship between effusion rate and flow length. Communicating uncertainty associated with lava flow hazards was a challenge throughout the crisis, but online distribution of information and direct contact with residents proved to be effective strategies for keeping the public informed and educated about flow progress and how lava flows work (including forecasting limitations). Volcanological and sociological lessons will be important for inevitable future lava flow crises in Hawai'i and, potentially, elsewhere in the world.

The general anisotropic form of the viscous heat generation term is developed for use in groundwater flow simulations. The 1-D solution is extended to more complex geometries by solving the equation for piece-wise linear or uniform properties and boundary conditions. A moderately complex example, the Eastern Snake River Plain (ESRP), is analyzed to demonstrate the use of the analytic solution for identifying important physical processes. For example, it is shown that viscous heating is variably important and that heat conduction to the land surface is a primary control on the distribution of aquifer and spring temperatures. Use of published values for all aquifer and thermal properties results in a reasonable match between simulated and measured groundwater temperatures over most of the 300 km length of the ESRP, except for geothermal heat flow into the base of the aquifer within 20 km of the Yellowstone hotspot. Previous basal heat flow measurements (110 mW/m super(2)) made beneath the ESRP aquifer were collected at distances of >50 km from the Yellowstone Plateau, but a higher basal heat flow of 150 mW/m super(2) is required to match groundwater temperatures near the Plateau. The ESRP example demonstrates how the new tool can be used during preliminary analysis of a groundwater system, allowing efficient identification of the important physical processes that must be represented during more-complex 2-D and 3-D simulations of combined groundwater and heat flow. Key Points: * An analytic solution is developed to simulate combined groundwater and geothermal heat flow * The general anisotropic form of viscous heat generation is derived for use in numerical solvers * The Peclet Number can be used to predict the persistence of thermal plumes JF - Water Resources Research AU - Burns, Erick R AU - Ingebritsen, Steven E AU - Manga, Michael AU - Williams, Colin F AD - USGS Oregon Water Science Center, Portland, Oregon, USA.

Stream food webs are connected with their riparian zones through cross-ecosystem movements of energy and nutrients. The use and impact of terrestrial subsidies on aquatic consumers is determined in part by in situ biomass of aquatic prey. Thus, stressors such as aquatic pollutants that greatly reduce aquatic secondary production could increase the need for and reliance of stream consumers on terrestrial resource subsidies. 2. To test this hypothesis, we surveyed stream fish, their diets and resource availability in 16 subalpine streams over a regional gradient of trace metals known to strongly impact aquatic insect communities (i.e. fish prey) in the Colorado Rocky Mountains, USA. 3. Fish increased their reliance on terrestrial insect prey as stream metals increased. Relative biomass of terrestrial insects in stomach contents of Brook and Brown Trout increased with respect to aquatic insect biomass and total stomach contents. Drifting insect biomass showed a declining trend for aquatic, but not terrestrial insects, over the metal gradient. Trout densities were unrelated to metal concentrations in streams where we found fish. 4. Synthesis and applications. Our results indicate that diets of aquatic consumers can become more terrestrial as aquatic stressors that limit in situ food production increase and that these subsidies may compensate for loss of aquatic resources. This work implies an important connection between preserving aquatic-terrestrial linkages and management of fish populations in stressed watersheds. Specifically, intact riparian zones and aquatic-terrestrial linkages are likely to be important for maintaining trout production in streams with moderate metal contamination.

Snails were maintained in static-renewal or recirculating culture systems with adults removed periodically to isolate cohorts of offspring for toxicity testing. This method successfully produced offspring for both species of pulmonate snails and for two hydrobiid species, P. robusta and Fluminicola sp. Toxicity tests were performed for 28 days with copper, ammonia, and pentachlorophenol in hard reconstituted water with endpoints of survival and growth. Tests were started with 1-week-old L. stagnalis, 2-week-old P. gyrina, 5- to 13-week-old P. robusta and Fluminicola sp., and older juveniles and adults of several hydrobiid species. For all three chemicals, chronic toxicity values for pulmonate snails were consistently greater than those for hydrobiid snails, and hydrobiids were among the most sensitive taxa in species sensitivity distributions for all three chemicals. These results suggest that the toxicant sensitivity of nonpulmonate snails in the family Hydrobiidae would not be adequately represented by results of toxicity testing with pulmonate snails.

We hypothesize that the climatic impact of boreal fires depends on local landscape heterogeneity such as burn severity, prefire vegetation type, and soil properties. To test this hypothesis, spatially explicit emission of greenhouse gases (GHGs) and aerosols and their resulting radiative forcing are required as an important and necessary component towards a full assessment. In this study, we integrated remote sensing (Landsat and MODIS) and models (carbon consumption model, emission factors model, and radiative forcing model) to calculate the carbon consumption, GHGs and aerosol emissions, and their radiative forcing of 2001-2010 fires at 30 m resolution in the Yukon River Basin of Alaska. Total carbon consumption showed significant spatial variation, with a mean of 2,615 g C m super(-2) and a standard deviation of 2,589 g C m super(-2). The carbon consumption led to different amounts of GHGs and aerosol emissions, ranging from 593.26 Tg (CO sub(2)) to 0.16 Tg (N sub(2)O). When converted to equivalent CO sub(2) based on global warming potential metric, the maximum 20 years equivalent CO sub(2) was black carbon (713.77 Tg), and the lowest 20 years equivalent CO sub(2) was organic carbon (-583.13 Tg). The resulting radiative forcing also showed significant spatial variation: CO sub(2), CH sub(4), and N sub(2)O can cause a 20-year mean radiative forcing of 7.41 W m super(-2) with a standard deviation of 2.87 W m super(-2). This emission forcing heterogeneity indicates that different boreal fires have different climatic impacts. When considering the spatial variation of other forcings, such as surface shortwave forcing, we may conclude that some boreal fires, especially boreal deciduous fires, can warm the climate.

Properly functioning riparian systems slow runoff and store water, thus regulating extreme flows; however, riparian areas across the west are in a degraded condition with a majority of riparian systems not in proper functioning condition, and with widespread catastrophic erosion of water-storing peat and organic soils. Headcuts are the leading edge of catastrophic channel erosion. We used aerial imagery (1.4-3.3-cm pixel) to locate 163 headcuts in riparian areas in the Sweetwater subbasin of central Wyoming. We found 1-m-the generally available standard resolution for land management-and 30-cm pixel imagery to be inadequate for headcut identification. We also used Structure-from-Motion models built from ground-acquired imagery to model 18 headcuts from which we measured soil loss of 425-720 m super(3). Normalized by channel length, this represents a loss of 1.1-1.8 m super(3) m super(-1) channel. Monitoring headcuts, either from ground or aerial imagery, provides an objective indicator of sustainable riparian land management and identifies priority disturbance-mitigation areas. Image-based headcut monitoring must use data on the order of 3.3 cm ground sample distance, or greater resolution, to effectively capture the information needed for accurate assessments of riparian conditions.

Gas hydrate exploration now integrates the unique pressure and temperature preconditions for gas hydrate occurrence with those concepts and practices that are the basis for conventional oil and gas exploration. We have aimed to assimilate the lessons learned to date in global gas hydrate exploration to outline a generalized prospecting approach as follows: (1) use existing well and geophysical data to delineate the gas hydrate stability zone (GHSZ), (2) identify and evaluate potential direct indications of hydrate occurrence through evaluation of interval of elevated acoustic velocity and/or seismic events of prospective amplitude and polarity, (3) mitigate geologic risk via regional seismic and stratigraphic facies analysis as well as seismic mapping of amplitude distribution along prospective horizons, and (4) mitigate further prospect risk through assessment of the evidence of gas presence and migration into the GHSZ. Although a wide range of occurrence types might ultimately become viable energy supply options, this approach, which has been tested in only a small number of locations worldwide, has directed prospect evaluation toward those sand-hosted, high-saturation occurrences that were presently considered to have the greatest future commercial potential.

AN - 1749991715; 26454754 AB - Intersex as the manifestation of testicular oocytes (TO) in male gonochoristic fishes has been used as an indicator of estrogenic exposure. Here we evaluated largemouth bass (Micropterus salmoides) or smallmouth bass (Micropterus dolomieu) form 19 National Wildlife Refuges (NWRs) in the Northeast U.S. inhabiting waters on or near NWR lands for evidence of estrogenic endocrine disruption. Waterbodies sampled included rivers, lakes, impoundments, ponds, and reservoirs. Here we focus on evidence of endocrine disruption in male bass evidenced by gonad histopathology including intersex or abnormal plasma vitellogenin (Vtg) concentrations. During the fall seasons of 2008-2010, we collected male smallmouth bass (n=118) from 12 sites and largemouth bass (n=173) from 27 sites. Intersex in male smallmouth bass was observed at all sites and ranged from 60% to 100%; in male largemouth bass the range was 0-100%. Estrogenicity, as measured using a bioluminescent yeast reporter, was detected above the probable no effects concentration (0.73ng/L) in ambient water samples from 79% of the NWR sites. Additionally, the presence of androgen receptor and glucocorticoid receptor ligands were noted as measured via novel nuclear receptor translocation assays. Mean plasma Vtg was elevated (>0.2mg/ml) in male smallmouth bass at four sites and in male largemouth bass at one site. This is the first reconnaissance survey of this scope conducted on US National Wildlife Refuges. The baseline data collected here provide a necessary benchmark for future monitoring and justify more comprehensive NWR-specific studies. Published by Elsevier Inc.

AN - 1859705730; 26769426 AB - Translocation is an increasingly important tool for managing endangered species, but factors influencing the survival of translocated individuals are not well understood. Here we examine intrinsic and extrinsic drivers of survival for critically endangered California condors (Gymnogyps californianus) whose wild population recovery is reliant upon releases of captively bred stock. We used known fate models and information-theoretic methods to compare the ability of hypothesized covariates, most of which serve as proxies for lead exposure risk, to predict survival rates of condors in California. Our best supported model included the following predictors of survival: age of the recovery program, precipitation, proportion of days observed feeding on proffered carcasses, maximum blood lead concentration over the preceding 18 months, and time since release. We found that as flocks have increased in size and age, condors are increasingly likely to range more widely and less likely to be observed feeding on proffered food, and these "wilder" behaviors were associated with lower survival. After accounting for these behaviors, we found a positive survival trend, which we attribute to ongoing improvements in management. Our findings illustrate that the survival of translocated animals, such as highly social California condors, is influenced by behaviors that change through time.

The right spine is intact and complete. The full specimen (SUSA 3163) is 53 mm long, and most other elements of the skeleton appear intact (except the lateral part of the left librigena, including the genal spine, which is missing). The right pygidial spine is 11 mm long, but the broken left spine preserves only slightly over 5 mm of the basal portion. There is no extra mineralization or deformation indicative of a pathology or teratological origin for the shortened spine, and the completeness of the rest of the skeleton suggests that the short spine is not a taphonomic modification. The blunt, rounded nature of the shortened spine, and its slightly rugose texture, suggest that it was injured and healed, perhaps as a result of failed predation by an unknown predator. The broken spine differs significantly from that in a previously described Tricrepicephalus (also a left) from another formation in that the previous specimen lost the entire spine at the base (up against the pygidium), and it was the spine-pygidium junction that healed in that specimen. In being short, blunt, and possibly regenerated, the pygidial spine of SUSA 3163 is similar to a broken and healed right genal spine in a specimen of Cedaria minor from the Weeks Formation (KUMIP 259299). Predation injuries are commonly recognized on pleural lobes (particularly posteriorly), pygidia, and cephala of trilobites; such injuries are expected on presumably defensive spines of the mineralized exoskeleton, but distinguishing these injured spines from those resulting from other causes can be difficult. Interestingly, injuries and other damage to the spines of olenelloid trilobites seem to be comparatively rare. The documentation of broken and healed, and otherwise pathological, pygidial spines in several specimens of Tricrepicephalus indicates both the defensive nature of the spines and the ability of the animals to survive what appears to be relatively frequent attempted predation, likely by other arthropods.

BLM officials chose this area based on its world-renowned fossil resources and multiple-use activities that take place in this region, leading to a delicate balance between science, and other activities such as recreation, grazing, mineral extraction, and development. This position began in 2013, and with the assistance of yearly GeoCorps interns, has made incredible strides in protecting and preserving fossil resources using scientific principles and expertise, while developing and implementing plans to increase public awareness about the significance of paleontological resources. GeoCorps interns have uncovered new dinosaur tracksites, worked on dinosaur excavations, given tours and presentations, discovered and documented new fossils sites, monitored existing sites, and worked to improve publicly interpreted fossil areas. Projects have included the development of a GIS paleontology database, the creation of a Women in STEM Career Day for local high schools, working with area tribes to learn and understand how fossils play an important roll in our cultural landscape and regional mythology, teaching visitors to the Moab area about why fossils are important and need protection, and how to visit our numerous public fossil sites with respect. With the assistance of GeoCorps interns, the BLM Canyon Country Paleontology Program continues to thrive, creating a much needed paleontology field-based model for the rest of the BLM. The success of the district paleontology program has provided the precedent for other field/district offices to have their own staff paleontologists in the future.

N1 - Last updated - 2017-01-24 ER - TY - JOUR T1 - Working in wilderness areas and wilderness study areas: the removal of two pentaceratops partial skeletons by helicopter AN - 1861112396; 787347-100 AB - The San Juan Basin of northwestern New Mexico is well known for the presence of late Cretaceous vertebrate fossils. These fossils are typically found in the Fruitland/Kirtland Formation exposed within the Bureau of Land Management administered Bisti/De-Na-Zin Wilderness Area and the Ah-shi-sle-pah Wilderness Study Area. Recently researchers from the New Mexico Museum of Natural History conducting paleontological surveys in the area discovered the remains of two separate Pentaceratops skeletons; one a juvenile in the Bisti/De- Na-Zin WA and an adult within the Ah-shi-sle-pah WSA. Since these two specimens were found in protected areas in-depth analysis was required to ensure that the "wilderness characteristics" were preserved within the Bisti/De-Na-Zin WA and that the "wilderness characteristics" within the Ah-shi-sle-pah WSA were not impaired so as to make it unsuitable for future Wilderness designation. Since the use of mechanized equipment is prohibited in both Wilderness Areas and Wilderness Study Area, the field crews had to stage outside of the protected areas and carry all equipment into both sites. Once jacketed the Pentaceratops specimens each weighed several thousand pounds making removal by hand impossible. We then analyzed the use of a helicopter for retrieval. This method was determined to be the "minimum tool" required to safely remove the specimens while meeting the rules for working in Wilderness Areas and Wilderness Study Areas. Since a helicopter is mechanical and would typically be prohibited, it was allowed for this 'one time' use providing it would not physically land on the ground. Because no private sector helicopters were available for this project, the New Mexico National Guard agreed to assist in the removal as part of a training exercise. The day before the airlift members of the BLM, NMMNH, and the National Guard worked together to flip the jackets into cargo nets. The following day the New Mexico National Guard brought in two Black Hawk helicopters, hooked onto the cargo nets, and flew the jacketed fossils outside the protected areas to trucks where they were transported to the NMMNH for preparation, exhibit, and permanent storage.

While there may be some intraspecific variation in the details of shell color patterns, distinctive underlying elements that unify species are commonly present. In the vast majority of fossil shells, pigments have deteriorated or disappeared completely to the human eye. Hidden patterns may be enhanced or revealed by bleaching the shells in a dilute solution of household bleach and water and viewing them under ultraviolet (UV) light. Previous work by Pacaud and Pons (2013) on French and British Athleta has established the existence of a previously unknown species (A. yvonnae) based only on distinct color pattern differences. Here we aim to determine if residual color patterns can be used as a character by which to discriminate various fossil species of the genus Athleta from Eocene deposits of the US Gulf Coastal Plain from one another. If bleaching fossil species of Athleta causes them to display remnant color patterns when placed under UV light, and these remnant color patterns are similar for members of the same morphospecies, yet different between morphospecies, then residual color patterns will be considered a species-level trait consistent with the preexisting morphospecies designation. On the other hand, if these remnant color patterns show multiple color pattern morphs within a single morphospecies, one may conclude the possible existence of two or more cryptic fossil species. In all, eight species of Athleta from Eocene strata in the Gulf Coastal Plain were subject to the bleaching treatment and photographed under UV light. Following the treatment, we were able to document residual color patterns in multiple specimens of all eight species. It was determined that different morphospecies of Athleta exhibit different color patterns and that the patterns can be categorized as dashes, bands, streaks and/or blotches. Some species shared residual color patterns. For example, Athleta symmetrica, A. sayanus, and A. clayi all displayed a similar pattern of thin spiral bands in varying degrees of coverage. Further phylogenetic implications will be discussed.

Floras of late Eocene age range from broadleaved evergreen and paratropical rain forests of the Pacific coast lowlands to warm temperate upland forests in the continental interior. Late Eocene upland floras such as Florissant provided sources of temperate taxa that dispersed or evolved to form new forest types in cooler climates of the Oligocene lowlands. Oligocene floras of the Pacific coast (e.g., Bridge Creek flora of Oregon) show strong similarity to the deciduous hardwood forests of eastern Asia and eastern North America but less resemblance to modern west coast forests, whereas interior floras of the southern Rocky Mountains and Rio Grande Rift (e.g., Creede flora of Colorado, and Hermosa and Hillsboro floras of New Mexico) "modernized" within that region during the Oligocene and developed strong affinities to the region's modern flora. The early Oligocene Bridge Creek flora (31.8-33.6 Ma) is a classic example of the type of vegetation that became widespread at low elevations following the Eocene-Oligocene cooling. The flora indicates a temperate broad-leaved deciduous forest similar to the modern Mixed Mesophytic forest. By contrast, Oligocene floras of the southern Rocky Mountains have a strong coniferous component and are cool temperate, indicating moderately high elevations. The transitional Eocene-Oligocene Antero flora (33.76 Ma) contrasts with the nearby latest Eocene Florissant flora (34.07 Ma) by having a significant reduction in warm temperate angiosperm hardwoods and an increasing abundance of Pinaceae, implying response to Eocene-Oligocene cooling. The late Oligocene Creede flora (26.8 Ma) represents a cool temperate montane Mixed Coniferous Forest dominated by Pinaceae mixed with angiosperm shrubs and having strong similarities to the modern Rocky Mountain flora. The early Oligocene Hermosa and Hillsboro floras (28.1-33.6 Ma) of the Rio Grande Rift indicate a cold temperate subalpine forest at very high elevation and are dominated almost totally by bristlecone pine. Collectively, these floras provide evidence for dynamic climate and elevation history of western North America during the late Eocene through the Oligocene.

Westside Road is the main access to several popular trail heads on the western face of Mount Rainier, and is no longer accessible to personal vehicles because of outburst floods born from Tahoma Glacier in response to a changing climate. These floods, along with past road construction, have led to the degradation of critical riparian gallery forests alongside Tahoma Creek. Applied geomorphic-conscious construction leave a new landscape that is barren and more difficult for natural riparian succession to begin. In this novel experiment at Mount Rainier National Park, we seek to integrate phyto-engineering construction principles using Sitka willow (Salix sitchensis) and Black cottonwood (Populus trichocarpa) with the geologic engineering method of building Large Woody Structures (LWS) to mitigate road edge erosion. Our soil bioengineering flood protection methods include building willow wattle fences, using live willow stakes to entrain loose channel silt in the Tahoma Creek bed, and planting native species specific to erosion control. Using living structures that will continue to grow is a sustainable and more cost-effective method of construction. Our design takes advantage of the natural asexual dispersal methods, high tolerance to disturbance on site, and high flexibility of growth conditions of pioneer species, S. sitchensis and P. trichocarpa. Both species play a key role in the successional development of a riparian system on our site, and provide slope stabilization via a network of roots. Live willow stakes also contribute to the rock armament by quickly and effectively rooting throughout the LWS. This new ecological restoration approach will be a partnership of both living wood and rock flood mitigation methods, creatively seeking to restore the integrity of the Westside Road to its former popularity while repairing its crucial ecological system and creating an overall stronger solution. This study also serves as an introduction to the restoration theory of adaptive management by effectively testing our design approach on a high profile, highly volatile area of Mount Rainier National Park.

Studying the dynamics of this storm and the resultant flooding provides an opportunity to improve our understanding of the flooding process, the geomorphological hazard and the link between extreme precipitation, basin response, and runoff. Our investigation collected stratigraphic and radiocarbon data in six basins along the Front Range between Coal Creek Canyon and Estes Park to evaluate and compare the magnitude and return period of the flood. In terms of rainfall intensity, the September 1938 and June 1965 storms produced similar spatial and temporal precipitation patterns with very large rainfall totals. A unique feature of the September 2013 storm was the occurrence of mesolows that aided in focusing intense precipitation over small spatial domains for several hours. In many locations, the precipitation amounts were estimated to be equal to or above a 1 in 1000 year event. However, the flooding response was not proportional (i.e., not AEP neutral) as many locations experienced floods estimated to be equal to or less than a 1 in 100 year event. Topographic surveys of the channel geometry and elevation data for high water marks were collected to facilitate the accurate reconstruction of flood peak discharges which were computed using in most cases a single cross-section slope conveyance method and at one site a 1D-HEC-RAS model. These data were used to make flood frequency estimates for the September 2013 flood using historical records. Radiocarbon ages were collected and used for age determination of past flood deposits at most sites as well as the interpretation of non-exceedance bounds where stable surfaces were identified. The results of this study highlight the differences in extreme floods between adjacent basins that appear to correlate better to the physical characteristics of the basins rather than specific characteristics of the storm. Based on flood frequency and discharge results the 2013 flood can be associated to a return period as low as 25 and 50 years on the Middle Saint Vrain and Coal Creek drainages respectively, while on the North Fork of the Big Thompson, the South St Vrain and Left Hand drainages the return period varies respectively from 150 year, to 200 years and 200 to 350 years.

AN - 1861108799; 787362-30 AB - Fe-oxide -aapatite (IOA) deposits are increasingly recognized as important and economically viable sources for critical rare earth elements (REE). The origin of such deposits, which are called Fe-oxide - copper - gold (IOCG) or Kiruna-type deposits, , are widely debated and enigmatic. Two end member models are magmatic or metasomatic origin. Therefore, geochronology is required to determine the origin model. The eastern Adirondack Mountains (that be rocks exposed in GAJ) are host to numerous IOA-type depositsthat are associated with the emplacement of the post-kinematic,aleucogranitoid of the ca. 1.05 Ga Lyon Mountain granite gneiss. The ore bodies contain widespread Na-fluid alteration in surrounding host rocks indicative of Kiruna-type deposits. We present in-situ major and trace element data, and geochronology from monazite, apatite, and zircon, which demonstrates that fluid-mediated recrystallization of ore phases cause several generations of geochronometers that span as much as 60'smy?). One example from the Cheever Mine, NY, consists of symplectite monazite intergrown with allanite, apatite, and quartz. Textural evidence suggests that monazite and apatite formed during multiple stages to form several generations of compositionally distinct monazite, apatite, and allanite, with a likely starting composition of britholite-Ce. Geochronology of monazite symplectite suggests formation at ca. 0.98 Ga, ca. 60 my after ore formation. However, no zircon has been found in-situ within the ore, and thus its petrogenetic significance remains unknown. Therefore, in order to utilize geochronometers within such deposits, detailed textural and in-situ analyses are critical to establish the processes pertaining to their formation. Analysis of one type of mineral may yield age data indicative of secondary processes after formation of the ore. These data suggest that both magmatic and metasomatically enriched ore of Kiruna-type deposits in the Adirondack Grenvillian rocks have a component of both origin models.

U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center, while continuing to operate Landsat data collection, archive, and distribution, has initiated development of an advanced capacity that will efficiently deliver user-specified information derivatives that transform the availability of lower-level data into analysis ready products for use in mapping and modeling applications. Using advanced processing frameworks and applications programming interfaces (API), Landsat scenes are deconstructed and stored as pixels in a datacube from which seamless, calibrated, georeferenced, spatially projected, and quality-masked areas of interest, co-registered temporal layer stacks, temporalaor band composites, and vectors of pixel values for specific point locations drilled down through data layers can be easily extracted. The need to perform time, network, and disk consuming pre-analysis data manipulations is ameliorated by the abstraction of traditional World Reference System-2 (WRS-2) scenes into parcels of information that can be filtered for quality conditions and readily packaged to user specifications for format, map projection, band selection, geographic extent, and time period. This exciting new information access methodology is currently evolving through a prototypical phase and is expected to achieve an initial operating capability over the continental U.S. by November 2017.

Homesteader Charlotte Hill collected fossil plants and insects beginning in the 1870s and provided many of the fossils that became the first type specimens. Biologist Wilmatte Cockerell worked with her husband T.D.A. Cockerell on expeditions to the site in 1906-08 and is attributed for finding many of the most outstanding specimens. The first scientific publication by a woman was contributed by Elizabeth Britton, a bryologist who described a rare fossil moss from Florissant in 1907 and who was one of only few women listed in the first edition of American Men of Science. Although outnumbered by men over the years, the contribution by women reemerged in force as the fossil beds came under threat of real estate development in 1969. Estella Leopold, who was a pioneering palynologist at USGS during the 1960s, organized a grassroots effort to save the site from destruction by real estate developers. Along with alpine ecologist Beatrice Willard and environmental activist Vim Wright, these women and others were ready to stand in front of bulldozers to block the construction. This effort, assisted by legal representation, resulted in a restraining order that gave time for Congress to establish Florissant Fossil Beds National Monument on August 20, 1969. Leopold was recognized for these achievements as the recipient of the International Cosmos Prize in 2010, the Paleontological Society Medal in 2013, and the Palynological Society Medal in 2013. With construction of a new visitor center in 2013, exhibits were developed highlighting current and past research of Florissant, with many of the panels featuring women researchers. The monument has supported an active paleontology internship program since 1997, hosting 60 interns and student employees of which 50 were women early in their scientific careers. The outcome of their many projects includes research, inventory and monitoring of fossil sites, excavations, collections management, and development of websites, educational outreach, and curriculum design. The role of women has been an important one to the foundation, conservation and ongoing history of the Florissant Fossil Beds National Monument.

Using distinct epicenter lineations and focal mechanism trends, we identify a prevailing set of near-vertical conjugate fault orientations in most clusters of induced seismicity. The observed strong preferential shear slip along the faults with one of these orientations over a wide area and at all azimuthal directions from the well is consistent with event triggering on pre-existing faults due to an increase in pore pressure. This assumes a simple Mohr-Coulomb stress model and a uniform regional maximum horizontal stress direction consistent with observations from the World Stress Map Project. The earthquake epicenters and focal mechanisms also indicate a third fault orientation, observed only in a concentrated area near the injection well. The shear slip observed along this third fault orientation is inconsistent with the simple pore-pressure triggering model and suggests that additional factors are present, such as a local rotation of the horizontal stresses, a different prevailing orientation of pre-existing faults, or event triggering due to stress transfer from injection-related subsurface deformation. Individual fault segments along which induced seismicity occurs can be seismically active for several years prior to the occurrence of a larger event that ruptures the entire fault segment. In the case of the MW 4.0 induced earthquake that occurred in January, 2013, most of the fault segment on which it occurred experienced dozens of smaller events during the preceding 13 years. Hence, previously or currently active fault segments identified by epicenter lineations and focal mechanisms can provide estimates of the locations and maximum magnitudes of potential future induced earthquakes. The longest potentially contiguous, seismically active fault segment identified at PVU lies within a 3.3-km radius of the injection well and has a length of nearly equal 4.0 km, yielding maximum magnitude estimates of MW 5.0 to MW 5.7 for a circular crack model and assumed stress drops of 2 to 20 MPa.

The former boundary of Great Sand Dunes National Monument encompassed only the dune field; however, the expanded boundary incorporates other aeolian deposits such as a sand sheet and an inland sabkha. Developed on these aeolian deposits is a fluvial system that originates in the Sangre de Cristo Mountains above the dunes, flows around the dune field and terminates on the sand sheet or the playas of the inland sabkha. There are also streams that emerge from the sand sheet and terminate in playas. The National Park Service is negotiating the purchase of lands within the expanded park boundary that are part of the historic Medano Ranch, currently owned by The Nature Conservancy. These lands are in the southwest portion of the Park where elevations are lowest and the distal stretches of several streams are found. aAs a ranch, the land use is agricultural and stream flow is diverted through a network of ditches to irrigate meadows. aOnce Park management begins, agricultural activity will cease and an effort to restore natural systems will take place. It is rare in the western US to have and entire stream system be under natural flow conditions.There are a number of studies underway to determine the effects of the potential land use change. This presentation will focus on the effort to determine where the natural channels of Sand, Big Spring, and Little Spring Creeks would develop if not diverted by ditches. The area is broad, very flat, covered by meadows and 140 years of ranching has obscured signs of historic channels.aLidar data and aerial imagery are available and will be used to indicate where streams would flow through meadows as broad, shallow, grassy channels, and then fill ponds along a lunette front. There is also a need to know where each stream would breach the lunettes, and which playas they would flow into. aThe goal is to restore natural processes, and also address how changing water use might impact neighboring water rights holders.

This mutually beneficial program advances the national monument's goals to provide paleontological conservation, interpretation, and research in the monument's new paleontology lab and museum while also benefiting students by refocusing their educational direction and advancing career options for a number of recent participants.aThe intern program has been sponsored by the Geoscientists in the Parks, Association for Women Geoscientists, Mosaics in Science, Environmental Stewards, Environment for the Americas, and University of Colorado Archives.aOngoing projects have included inventory and monitoring of fossil sites, paleontological excavations, collections management, scientific research, investigation of new methods for conservation of fossil shale and petrified trees, curriculum development, website creation, exhibit preparation, public outreach, preparation of funding proposals, digitization of collections, compilation of a GeoPark proposal, archives management, and creation of a wide array of databases. Recent projects have involved development of educational and exhibit media, including an innovative virtual tour of the new Paleontology Lab and video content about paleontology topics for a kiosk in the new visitor center.aInterns recently developed new trailside exhibits and designed a geologic trails map, both of which enhance visitor education by providing credible scientific content.aInterns have provided extensive collections management including the move of collections into the new facility, stabilization of fragile fossils, and identification of fossil plants and insects.aMany Florissant interns have continued their education and completed graduate degrees in paleontology or related fields, and some have completed theses related to projects initiated during their internships. Participants acquire practical experience in paleontological resource and collections management, which is rarely covered in academic programs. Such practical experience is potentially valuable for future employment, and recent interns have gone on to positions at museums, universities, government agencies, and consulting firms, enabled in part by skills developed as interns.

The TCP was built in the 1960's to provide potable water to Phantom Ranch, Indian Garden, and the South Rim village by conveying water from Roaring Springs on the North Rim via a gravity assisted feed through 24 km of waterline. The infrastructure is decades beyond its design life and fails annually, occasionally causing severe water shortages. The TCP will be either replaced in-kind or with an in-take structure and pumphouse near the confluence of Bright Angel Creek (BAC) and the Colorado River. Park hydrologists, and consultants, have been conducting hydrologic, geophysical, and geotechnical studies to inform the decision on the future TCP. This presentation provides an overview of the surface water studies related to the TCP decision. Studies associated with replacement in-kind include a paleontologic risk assessment utilizing geomorphic variables, and a risk assessment of mass movement along the current pipeline footprint. Studies associated with moving the in-take to near the terminus of BAC include an analysis of the increased flow (+1.5 cubic feet per second) through the majority of the creek as the in-take is moved from Roaring Springs (at the upstream extent of BAC) to the lower end of the creek. Increased flow from the spring will change the temperature of BAC ( nearly equal 2 C warmer) and pH as flow is restored to the majority of the creek as well as provide more water for aquatic habitat. A flood risk analysis using HEC-RAS was also completed through Phantom Ranch, alluvium depth determined using geophones, and a study of hyperheic exchange rates at select locations in BAC. Studies serving both design options include an analysis of environmental flows for native fishes, long-term hydrograph analysis (1923-present), nutrient cycling in tributary creeks, and the maintenance of 4 NPS streamgauges. These concurrent studies provide the most comprehensive analysis of Grand Canyon tributary streams to date and should inform future management and tributary science endeavors.

The report, "Coastal Adaptation Strategies: Case Studies," was compiled to inspire action, innovation, and dialogue among park managers, coastal scientists, and other coastal management agencies that are responsible for researching and protecting natural and cultural resources. Actions used by NPS managers to combat climate change in an already dynamic coastal zone are described through 24 case studies in the report. Examples include:aGateway National Recreation Area in New York has restored salt marsh elevation in Jamaica Bay through the addition of sediment and vegetation; and in a lab on Ofu, one of the islands of the National Park of American Samoa, the facility studies unique adaptations of Ofu coral and to determe the cause of coral loss and damage.

Four BLM pilot sites participated in this effort: Canyons of the Ancients National Monument in Colorado, Red Cliffs and Beaver Dam Wash National Conservation Areas in Utah, BLM's Taos Field Office in New Mexico, and BLM's Tuscarora Field Office in Nevada. The focus of the case studies was on practical applications of nonmarket valuation. USGS worked directly with BLM field staff at the pilot sites to demonstrate the process of considering nonmarket values in BLM decisionmaking and document the questions, challenges, and opportunities that arise when tying economic language to projects. As part of this effort, a Web-based toolkit, available at https://my.usgs.gov/benefit-transfer/, was updated and expanded to help facilitate benefit transfers (that is, the use of existing economic data to quantify nonmarket values) and qualitative discussions of nonmarket values. A total of 53 new or overlooked nonmarket valuation studies comprising 494 nonmarket value estimates for various recreational activities and the preservation of threatened, endangered, and rare species were added to existing databases within this Benefit Transfer Toolkit. In addition, four meta-regression functions focused on hunting, wildlife viewing, fishing, and trail use recreation were developed and added to the Benefit Transfer Toolkit. Results of this effort demonstrate that there are two main roles for nonmarket valuation in BLM planning. The first is to improve the decisionmaking process by contributing to a more comprehensive comparison of economic benefits and cost when evaluating resource tradeoffs for National Environmental Policy Act analyses. The second is to use economic language and information on economic values, either qualitative or quantitative, to improve the ability to communicate the economic significance of the resources provided by BLM-managed lands. Findings also indicate that the use of existing economic data to quantify nonmarket values (that is, benefit transfer) poses unique challenges because of the scarcity of both resource data and existing valuation studies focused on resources and sites managed by BLM. This highlights the need for improvements in the collection of resource data at BLM sites, especially visitor use data, as well as an opportunity for BLM's Socioeconomics Program to strategically identify priority areas, in terms of both resources and geographic locations, where primary valuation studies could be conducted and the results used for future benefit transfers. Finally, whereas qualitative discussions of nonmarket values do not facilitate the comparison of monetized values, they can provide a manageable next step forward in providing more comprehensive information on nonmarket values for BLM plans and project assessments.

A comprehensive understanding of conditions during the Piacenzian serves as both a conceptual model and a source for boundary conditions as well as means of verification of global climate model experiments. In this paper we present the PRISM4 reconstruction, a paleoenvironmental reconstruction of the mid-Piacenzian ( approximately 3 Ma) containing data for paleogeography, land and sea ice, sea-surface temperature, vegetation, soils, and lakes. Our retrodicted paleogeography takes into account glacial isostatic adjustments and changes in dynamic topography. Soils and lakes, both significant as land surface features, are introduced to the PRISM reconstruction for the first time. Sea-surface temperature and vegetation reconstructions are unchanged but now have confidence assessments. The PRISM4 reconstruction is being used as boundary condition data for the Pliocene Model Intercomparison Project Phase 2 (PlioMIP2) experiments.

Thousands of Late Pleistocene "megafauna" vertebrate tracks and trackways known as the "White Sands Megatracksite", have been found in sediments in and around the lacustrine deposits. Fossil prints were first described from the Tularosa Basin in the 1930's, but have only recently been discovered within White Sands National Monument. The trace fossil assemblage is dominated by proboscidean (mammoth) footprints along with associated camelid (camel-like), undetermined artiodactyl, and large and small carnivore tracks. These fossil tracks have unusual preservation in soft gypsiferous lacustrine and playa lake-margin sediments. Here we describe this preservation in order to better understand paleo environments and aid in preservation and management. Prints are preserved in soft gypsum and carbonate sediment, making them extremely fragile and susceptible to rapid weathering once exposed. Some prints and trackways have an ephemeral expression, only visible when sediment moisture is high enough to create a contrast with surrounding sediment. The prints can be raised above or depressed below the surface. We interpret the raised tracks to represent the compressed sediment below the track exposed by wind erosion, and in some cases affected by diagenetic alteration to, or precipitation of dolomite. Sediment surrounding these tracks are distorted as seen in natural vertical exposures or excavations into track-bearing strata. Sediment that infills the tracks includes fine or coarse grained gypsum sand, siliciclastic mud, and dolomite. Many tracks are very fragile, but those comprised of dolomite are comparatively resistant. In addition to the prints, layers of vegetation have been found preserved beneath and above many of the tracks, and hair and possible coprolites have also been found in association with the trackways. This ongoing survey continues to discover new trackways as they are exposed from eroding sediment. This study is part of an ongoing effort to catalog and correlate sediments and trackways at White Sands National Monument to better plan for their preservation and interpretation.

This spring, Roaring Springs, is fed entirely from focused, ephemeral snowmelt that sinks into the karst landscape above the rims and emerges in the canyon walls 3,500 feet below. Current water infrastructure that pipes this water from the spring back to the rims has far outlived its life expectancy and the park is currently looking at alternatives for replacing it. As part of the National Environmental Policy Act (NEPA) procedures, the park is undertaking numerous studies to determine the environmental impact of these alternatives. There is a lack of borehole data, deep geophysical surveys, or other data to characterize the deep aquifers away from the outcrops of the Canyon. To improve the characterization of the aquifer, a combination of dye tracing, hydrograph, chemograph, and ion analyses are being used to establish a baseline understanding of aquifer behavior. These data are providing critical information to guide the NEPA process, leading GRCA towards the least impactful and most sustainable option for the future of the park's water supply system.

Permitting is required by law and may involve several steps including environmental review, and because this involves a variety of officials, there is a certain amount of time involved in issuing the permit. Permitting officials in the BLM are colleagues who can advocate for geologists and paleontologists and guide professionals through the process. When working in paleontology there are significant differences in the processes used to issue "Consulting," "Survey," or "Excavation" permits, with the Excavation process requiring the most involved work on the part of BLM. There is no geological or research permit issued by BLM, so that geoscience work is generally authorized under a Special Recreation Permit (SRP). A further consideration includes designation of the land, such as Area of Critical Environmental Concern (ACEC), Wilderness Study Area (WSA), National Monument, etc., which may require additional considerations for protecting other resources. Activities that may need permits include but are not limited to bringing groups such as field camps on public land; collecting rock samples for research; drilling cores for any purpose; prospecting, surveying, documenting, and collecting fossils of any kind for research purposes (including non-vertebrate, trace, plant, and vertebrate fossils); collecting or disturbing cultural artifacts or historic sites, documenting and making molds of trace fossils or other features; trenching to obtain fresh rock exposures; or any other action that has the potential for ground and/or fossil disturbance. Permitting officials at the BLM want to partner with geoscientists to help research to happen on public lands and will work hard to navigate the multiple mandates for land management in order to facilitate your project.

Some museums have faltered over this long-term commitment, however, and specimens risk loss or neglect when researchers retire, museums transfer collections or collection locality ownership changes. The history of Florissant fossil beds, and of the museums that care for specimens collected there over 14 decades, mirrors that of many paleontological sites across the American West. Albert C. Peale of the Hayden Survey first reported the petrified wood and fossiliferous shale near Florissant, Colorado in 1873. Notable collectors and taxonomists followed in the effort to document these resources, beginning with the first Princeton Scientific Expedition and Samuel H. Scudder and continuing into the early 20th century and beyond with T.D.A. Cockerell, H.F. Wickham and others. Large museums across the East Coast and United Kingdom acquired significant collections from Florissant, through funding excavations or being associated with collectors. These few institutions grew to become the dominant repositories for material from distant frontiers and hence the only places where researchers could compare material to study systematics and biogeography. Scudder and Cockerell utilized fossil insects and plants from Florissant to develop early, specimen-based hypotheses on evolution and species range shifts. Florissant Fossil Beds National Monument was established in 1969, and the park maintains on-site collections and public exhibits of material excavated since then. With the cooperation of 17 museums, records of all published specimens from Florissant have been incorporated in a searchable database. The process of museum research no longer demands that a researcher visit a major institution to compare material; digitized databases, specimen loans and online publications now facilitate remote collaborations. Even as research techniques and curation practices change, and as the geographic and scientific frontier expands, the mandated role of museums in conserving original specimens remains crucial in providing material to further investigations of life and earth processes.

We used the combination of mapping, stratigraphy, tephrochronology and soil development to interpret the history of a long lived paleo-Mohawk Lake. The well-developed shorelines and nearly 200 meters of well-preserved, tephra-rich lake deposits record deposition as far back as 740 ka. The type of shoreline varies along the same elevation from wavecut notches, pediments, and outwash terraces, which grade up to 215-m-above modern base level. Basinward, the sediment size decreases dramatically, with the stratigraphic signatures of a delta and numerous tephra beds deposited within. On the north side of the valley, fluvial-deltaic deposits sourced from moderate-sized streams also grade to a former base levels at the same, or similar, elevations.From these observations, we have interpreted a first order Mohawk Lake history for the past nearly equal 740 ka. Prior to 740 ka, Mohawk Valley occupied a similar elevation as today and lakes began to form intermittently in the valley until before about 600 ka, when the lake dramatically deepened. From nearly equal 600 ka to after MIS 8 or 6, lakes persisted throughout many glacial and interglacial transitions. Mohawk Lake almost certainly responded to these climatic changes; however, these climate fluctuations are not well documented by preserved shorelines. The stratigraphic and paleosol record thus far have provided some constraints on the magnitude of the lake level fluctuations, but this part of the study is ongoing. After MIS 8 or 6, the lake substantially increased in size and depth and ultimately overflowed westward through the MFFR, eroding its western sill which lead to incremental lowering until it emptied sometime before nearly equal 7 ka. This incredible record has remained relatively unstudied for many years in part because of the presence of organic-rich beds, originally interpreted as deposited in a shallow marsh setting. We have re-interpreted these deposits as possibly having been deposited in anoxic conditions and in moderate to deep lake levels. Many of the organic-rich beds are closely associated with numerous tephra beds and may be genetically linked.

These sinkholes act as the primary recharge points for many springs below the North Rim of the Grand Canyon, including Roaring Springs-the sole water source for the park and the 5.5 million annual visitors and employees. Roaring Springs is believed to have a large catchment centered within GRCA's Kaibab Plateau boundaries. However, a recent dye trace indicates that the karst network supplying this, and other major springs, is far more complex than previously assumed. New tracer results indicate that the complexity of the Roaring Springs catchment requires considerably more hydrologic monitoring and analysis than previously planned. This study examined the morphology and distribution of sinkholes on the Kaibab Plateau at GRCA using geospatial and field data to further delineate the variability in sinkhole recharge dynamics. Field measurements and observations were used to verify LIDAR-derived spatial models at both landscape and site scales. Although preliminary results suggest size, orientation, and distribution of sinkholes may be influenced by the structural geology of the region, formation of sinkholes does not appear to be limited to areas of known faults and fractures. Size and density may instead be indicative of the size of subsurface conduits feeding into fault and fracture-driven drainages. These results provide an important step towards understanding the complex groundwater dynamics of the Kaibab Plateau. Identifying the catchment that serves as the primary source to Roaring Springs and other major springs within GRCA is a necessary step towards assessing the vulnerability of the groundwater system and protecting GRCA's water supply from possible contamination.

A total of 188 streamgages, consisting of 6,536 years of record and a mean of approximately 35 years of record per streamgage, were used to develop the peak-streamflow regional-regression equations. The estimated AEPDs for each streamgage were computed using the USGS software program PeakFQ. The AEPDs were determined using systematic data through water year 2013. Based on previous studies conducted in Colorado and neighboring States and on the availability of data, 72 characteristics (57 basin and 15 climatic characteristics) were evaluated as candidate explanatory variables in the regression analysis. Paleoflood and non-exceedance bound ages were established based on reconnaissance-level methods. Multiple lines of evidence were used at each streamgage to arrive at a conclusion (age estimate) to add a higher degree of certainty to reconnaissance-level estimates. Paleoflood or nonexceedance bound evidence was documented at 41 streamgages, and 3 streamgages had previously collected paleoflood data. To determine the peak discharge of a paleoflood or non-exceedance bound, two different hydraulic models were used. The mean standard error of prediction (SEP) for all 8 AEPDs was reduced approximately 25 percent compared to the previous flood-frequency study. For paleoflood data to be effective in reducing the SEP in eastern Colorado, a larger ratio than 44 of 188 (23 percent) streamgages would need paleoflood data and that paleoflood data would need to increase the record length by more than 25 years for the 1-percent AEPD. The greatest reduction in SEP for the peak-streamflow regional-regression equations was observed when additional new basin characteristics were included in the peak-streamflow regional-regression equations and when eastern Colorado was divided into two separate hydrologic regions. To make further reductions in the uncertainties of the peak-streamflow regional-regression equations in the Foothills and Plains hydrologic regions, additional streamgages or crest-stage gages are needed to collect peak-streamflow data on natural streams in eastern Colorado. Generalized-Least Squares regression was used to compute the final peak-streamflow regional-regression equations for peak-streamflow. Dividing eastern Colorado into two new individual regions at -104 degrees longitude resulted in peak-streamflow regional-regression equations with the smallest SEP. The new hydrologic region located between -104 degrees longitude and the Kansas-Nebraska State line will be designated the Plains hydrologic region and the hydrologic region comprising the rest of eastern Colorado located west of the -104 degrees longitude and east of the Rocky Mountains and below 7,500 feet in the South Platte River Basin and below 9,000 feet in the Arkansas River Basin will be designated the Foothills hydrologic region.

This site is managed by the Bureau of Land Management exclusively for scientific research purposes. Paleontological studies conducted in the 1970s and 1980s, revealed ice age taxa (including extinct megafauna and smaller extant species) indicating that this location during the last glacial was likely at an important juncture between sub-glacial tundra and more temperate eco-zones, which can provide information on major extinction events in the Pleistocene. Recently, renewed excavations at NTC have yielded new fossils and other scientific samples, allowing for analysis of ancient DNA, stable isotopes, radiocarbon dating, as well as geochemical and palynological research. As the last decade of paleontological research has witnessed a marked increase in the use of 3D data capture for the purpose of documentation, evaluation, and preservation of fossil resources; state-of-the-art photogrammetric technology has been used to document the scientific resources of the cave. At Natural Trap Cave, photogrammetric documentation has included a holistic approach, with efforts to document the entirety of the main chamber below the mouth or "trap" of the cave. Excellent results are achieved from photogrammetry when the software solves for a robust camera calibration and when overlapping photographs are taken with proper geometry. These techniques elevate the camera from simply a device for capturing images to a virtual surveying and data collection instrument. We present the results from photogrammetric modeling efforts during the 2014, 2015 and 2016 field seasons at the cave. These data capture the entirety of the main chamber and are useful for monitoring the progress of excavation. More importantly, the use of 3D models allow for mapping of paleontological data and other results into a spatial context not easily compiled with a more traditional plan view cartographic effort drawn as part of an excavation. In turn, 3D data help facilitate the spatial and temporal relationships of the sedimentology, paleo-taxa variation, and paleo-environmental changes preserved within the cave.

This study focusses on the role of the Thabazimbi-Murchison Lineament (TML) during the emplacement of the Bushveld Complex. The TML is a large structure that runs along the northern boundary of the central Bushveld Complex and separates it from the northern lobe. Various authors consider the TML to have been exploited by a feeder to the northern lobe [1] and also to the whole Bushveld Complex [2], [3], [4]. Geophysical models focussing on the northern lobe show the presence of a feeder underneath the 110 mGal gravity high west of Mokopane and just to the north of the TML [1], [2]. Finn et al. [2] also modelled thicker Rustenburg Layered Suite (RLS) along the TML further westward towards Thabazimbi. Potential field data that focuses on the TML and the central Bushveld Complex to the south was modelled in three dimensions to study the distribution of the RLS along this structure, and investigate the role of the TML in the emplacement of the mafic rocks (Figure 1). Densities akin to those of the Lower Zone of the RLS (3200 kg/m3) had to be assigned to the modelled Bushveld feeder west of Mokopane in order to model the high gravity values. This concurs with the work of Van der Merwe [5] who modelled a feeder composed entirely of the Lower Zone. Boreholes drilled into the Lower and Marginal Zones in the northern part of the eastern lobe revealed the presence of an additional 750 m of ultramafic material underneath the Marginal Zone that was previously unknown [6]. This Basal Ultramafic Sequence (BUS) has a density of about 3100 kg/m3. It is therefore possible that this material may also constitute part of the feeder, supporting the modelled values. Positive magnetic anomalies and high gravity values occur all along the TML in the western lobe. In most instances the magnetic highs can be explained by banded iron formation (BIF) of the Penge Formation that has been brought close to the surface along the Droogekloof Thrust along the TML, but the BIF is too thin to account for the gravity high. The gravity data therefore indicate a possible deeper seated source for these anomalies. It was possible to model these anomalies by including very dense material similar to the Mokopane feeder (Lower Zone and BUS) in the thrust zone. The Droogekloof Thrust was active during the emplacement of the RLS [7] and the modelling suggests it may have been exploited as a feeder. In the eastern lobe magnetic and gravity anomalies are clearly associated with the RLS, but other than vertical displacement along the TML the models do not show the presence of mafic material within the fault itself.

Furthermore, these properties impact coal strength, coal blending during mining as well as coal's gas content, which is important for mining safety. In order for these processes and quantitative predictions to be successful, safer and economically feasible, it is important to determine and map chemical and compositional properties of coals accurately in order to infer these properties prior to mining. Ultimate analysis quantifies the principal chemical elements in coal. These elements are C, H, N, S, O and depending on the basis, ash and/or moisture. The basis for the data is determined by the condition of the sample at the time of analysis, with "as-received" basis being the closest to sampling conditions and thus to the in-situ conditions of the coal. The parts determined or calculated as the result of ultimate analyses are compositions, reported in weight percent, and pose the challenges of statistical analyses of compositional data. The treatment of parts using proper compositional methods may be even more important in mapping them, as most mapping methods carry uncertainty due to partial sampling as well. In this work, we map the ultimate analyses parts of the Springfield coal, from an Indiana section of the Illinois basin, USA, using sequential Gaussian simulation of isometric log-ratio transformed compositions. We compare the results with those of direct simulations of compositional parts. We also compare the implications of these approaches in calculating other properties using correlations to identify the differences and consequences.

Paleozoic rocks beneath some long-lived Chinese basins (for example, Sichuan and Tarim Basins) include shales rich in Type II organic matter that accumulated in deep marine environments and contain viable shale gas resources. In late Paleozoic to Triassic time, essentially all Chinese basins lost their open marine character (a situation that persists up to the present), with predominantly nonmarine to marginal-marine lithofacies as a result of tectonic convergence, suturing of cratonic blocks and uplift as Asia was assembled. Such lithofacies were conducive to development of basin-centered tight gas and coalbed methane accumulations, exemplified by gas fields in the Ordos Basin and analogous to several late Paleozoic and Mesozoic basins in the central and western interior of the United States. Some lacustrine shales and carbonates, rich in Type I organic matter (i.e., Late Permian of the Junggar Basin, and possibly parts of the Tertiary section in the Bohaiwan Basin) could represent an important lacustrine shale oil or tight oil resource, analogous to the mature parts of the Eocene Green River Formation in the western U.S. All Chinese basins contain a strong Mesozoic and Cenozoic tectonic overprint that increases the risk of hydrocarbon leakage. The U.S. Geological Survey (USGS) is quantitatively assessing undiscovered unconventional oil and gas in key Chinese basins as part of a larger effort to assess unconventional resources in priority basins worldwide. In the past year, we have completed geologic-based assessments of shale gas resources in the Sichuan Basin, and both tight and coalbed gas resources in the Ordos Basin. Future USGS assessments of unconventional oil and gas might include plays in the Junggar, Tarim and Bohaiwan Basins. In the Sichuan Basin [1], we estimated a mean 23.9 trillion cubic feet (TCF) of technically recoverable shale gas resources in Paleozoic strata, with a range from 4.5 to 58.4 TCF (F95-F5 probability). Six assessment units (AUs) were quantitatively assessed: Cambrian Qiongzhusi Platform and Foldbelt AUs (estimated to contribute 22 percent to the mean estimated resource), Silurian Longmaxi Platform and Foldbelt AUs (including uppermost Ordovician Wufeng Formation) (68 percent), and Permian Longtan Platform and Foldbelt AUs (10 percent). These AUs contain organic-rich shales that are the principal source rocks for conventional oil and gas in the Sichuan Basin. Since 2008, there have been multiple tests of gas potential in Cambrian, uppermost Ordovician, and lower Silurian shales in the Sichuan Basin. Commercial production of shale gas from the Longmaxi Formation in the southeastern foldbelt began in late 2012. In the Ordos Basin [2], we estimated mean technically recoverable resources of 28 TCF of tight gas (with a range of 13.2 to 50.0 TCF) and 5.6 TCF of coalbed gas (with a range of 2.3 to 11.3 TCF) in upper Paleozoic rocks from which large volumes of tight gas and coalbed gas have already been produced. The Upper Paleozoic Tight Gas AU covers the central part of the basin including the supergiant Sulige gas field. Sources of the gas are the coal beds in the upper Carboniferous Taiyuan and lower Permian Shanxi Formations. Reservoirs are mainly low-permeability sandstones, especially in the Shanxi and middle to upper Permian Shihezi Formations. The accumulation is a basin-centered gas-charged zone with an updip water leg. Future potential is envisioned as extending into lithofacies with lower porosity and permeability than what is being currently developed. The Upper Paleozoic Coalbed Gas AU is confined to the eastern flank of the basin; in this AU, the coals in the Taiyuan and Shanxi Formations are both the source of the gas and the reservoir.

Accurate estimation of coal reserves is essential for the long-term planning of mines and for the development of regional economic strategy and energy utilization planning. Coal thickness and quality characteristics vary greatly in a coal mine due to geological heterogeneities, which creates difficulties for deterministic prediction models. The heterogeneities include possible faults, the presence of multiple coal seams of variable thickness, tectonic deformations, and interburden layers. Kriging and simulation methods can, to some extent, overcome these challenges, and lead to more reliable estimates of reserves. However, such methods require the inversion of the data covariance matrix, which is a computationally expensive procedure especially for large data sizes. In this paper, we present a new, less computationally intensive method for reserves estimation, which is based on the stochastic local interaction (SLI) model. The SLI method constructs a spatial interaction matrix that accounts for the data values, their locations, and the sampling density variations. This construct does not require matrix inversion for parameter estimation and spatial prediction, and it thus leads to computational procedures that are less intensive than kriging. SLI provides an uncertainty measure analogous to the kriging variance. Calculation of this measure, however, requires the inversion of the SLI precision matrix. We compare SLI with ordinary kriging (OK) in terms of estimation performance using cross-validation analysis and computational time requirements. The comparison is conducted using approximately 13,000 drill-hole data of coal reserves from Campbell County, Wyoming, USA. To apply SLI, we divided the entire area in two overlapping spatial domains, while for OK we used a search neighbourhood of 1.1 km. SLI required about half the computational time needed for OK. The leave-one-out cross-validation measures have similar values without clearly favouring one method over the other.

EarthResourceML was initially developed for the Australian Chief Government Geologists Committee (CGGC) but is now under the governance of the Commission for Geoscience Information (CGI), a commission of the International Union of Geological Sciences (IUGS). EarthResourceML is the preferred standard for mineral resource data sharing initiatives and projects, such as the European Union's INSPIRE directive, EURare, Minerals4EU, and ProSUM projects, and the Australian AuScope, and Geoscience Portal projects. EarthResourceML v2.0 is the current version released in October 2013. The main elements of the EarthResourceML model cover mineral occurrences, mines, and mining activity. The standard describes the geological characteristics and setting of mineral occurrences, their contained commodities, and their mineral reserve, resource and endowment. It is also able to describe mineral exploration, mines and mining activities including processing, and production of concentrates, refined products, and waste materials. An additional EarthResourceML-Portrayal standard has recently been released. EarthResourceML-Portrayal delivers a simplified flat view of key elements of the full EarthResourceML data model. It can be used to standardise delivery of mineral resource data via Web Map Services (WMS) and simple features Web Feature Services (WFS SF0). EarthResourceML utilises the GeoSciML v3.2 Mapped Feature model [1] to describe spatial representations of mineral occurrences and mines, and the GeoSciML Earth Material model to describe host and associated materials. The CGI Geoscience Terminology Working Group [2] provides a range of standard vocabularies that can be used to populate EarthResourceML data services. Currently the EarthResourceML v.2.0 model defines 24 code list vocabularies and 19 of these are already adopted [3].

On the research train of thought and ideas of this method, there is a similar consensus with the "Recognizing the fundamental role in the formation of the Earth's energy and mineral resources in the process," which proposed by US Geological Survey in 2012, and showing today's Earth System Science development trends On the specific practices, could be divided into three parts: step one: data combing, to distinguish the connotation of various kinds of information, including topography, geothermal, geophysical characteristics, geochemical anomalies, geological records, e.g. sedimentary, metamorphic rock, igneous rocks, deposit; step two: under the modern theory to guide synthesis, concluding and using a variety of information, including: basic geology, mineral resources, deep geology, dynamic process; step three: Based on the geological process, the metallogenic process, take sequence of tectonic-magmatic-mineralization events as the foundation and key to carry out the resource assessment and prospect delineation, Compare the major events, focus is not just "once", more important is to identify current mineral resources saved state differences, namely to clarify geological processes, better understanding of mineralization. This method has ever been used on the research projects of China & Adjacent Areas [2], Pacific metallogenetic belts in Meso-Cenozoic between Eastern China and Western U.S. [3], and achieved good results.

The model was calibrated and validated with lake temperature data collected from 1994 to 2011. Wind and air temperature data from three general circulation models and two representative concentration pathways were used to simulate the change in lake temperature and the frequency of deep ventilation events in possible future climates. The lumped model air2water was used to project lake surface temperature, a required boundary condition for the lake model, based on air temperature in the future climates. The 1DDV model was used to simulate daily water temperature profiles through 2099. All future climate scenarios projected increased water temperature throughout the water column and a substantive reduction in the frequency of deep ventilation events. The least extreme scenario projected the frequency of deep ventilation events to decrease from about 1 in 2 years in current conditions to about 1 in 3 years by 2100. The most extreme scenario considered projected the frequency of deep ventilation events to be about 1 in 7.7 years by 2100. All scenarios predicted that the temperature of the entire water column will be greater than 4 degrees C for increasing lengths of time in the future and that the conditions required for thermobaric instability induced mixing will become rare or non-existent. The disruption of deep ventilation by itself does not provide a complete picture of the potential ecological and water quality consequences of warming climate to Crater Lake. Estimating the effect of warming climate on deep water oxygen depletion and water clarity will require careful modeling studies to combine the physical mixing processes affected by the atmosphere with the multitude of factors affecting the growth of algae and corresponding water clarity.

A total of 188 streamgages, consisting of 6,536 years of record and a mean of approximately 35 years of record per streamgage, were used to develop the peak-streamflow regional-regression equations. The estimated AEPDs for each streamgage were computed using the USGS software program PeakFQ. The AEPDs were determined using systematic data through water year 2013. Based on previous studies conducted in Colorado and neighboring States and on the availability of data, 72 characteristics (57 basin and 15 climatic characteristics) were evaluated as candidate explanatory variables in the regression analysis. Paleoflood and non-exceedance bound ages were established based on reconnaissance-level methods. Multiple lines of evidence were used at each streamgage to arrive at a conclusion (age estimate) to add a higher degree of certainty to reconnaissance-level estimates. Paleoflood or nonexceedance bound evidence was documented at 41 streamgages, and 3 streamgages had previously collected paleoflood data. To determine the peak discharge of a paleoflood or non-exceedance bound, two different hydraulic models were used. The mean standard error of prediction (SEP) for all 8 AEPDs was reduced approximately 25 percent compared to the previous flood-frequency study. For paleoflood data to be effective in reducing the SEP in eastern Colorado, a larger ratio than 44 of 188 (23 percent) streamgages would need paleoflood data and that paleoflood data would need to increase the record length by more than 25 years for the 1-percent AEPD. The greatest reduction in SEP for the peak-streamflow regional-regression equations was observed when additional new basin characteristics were included in the peak-streamflow regional-regression equations and when eastern Colorado was divided into two separate hydrologic regions. To make further reductions in the uncertainties of the peak-streamflow regional-regression equations in the Foothills and Plains hydrologic regions, additional streamgages or crest-stage gages are needed to collect peak-streamflow data on natural streams in eastern Colorado. Generalized-Least Squares regression was used to compute the final peak-streamflow regional-regression equations for peak-streamflow. Dividing eastern Colorado into two new individual regions at -104 degrees longitude resulted in peak-streamflow regional-regression equations with the smallest SEP. The new hydrologic region located between -104 degrees longitude and the Kansas-Nebraska State line will be designated the Plains hydrologic region and the hydrologic region comprising the rest of eastern Colorado located west of the -104 degrees longitude and east of the Rocky Mountains and below 7,500 feet in the South Platte River Basin and below 9,000 feet in the Arkansas River Basin will be designated the Foothills hydrologic region.

Four BLM pilot sites participated in this effort: Canyons of the Ancients National Monument in Colorado, Red Cliffs and Beaver Dam Wash National Conservation Areas in Utah, BLM's Taos Field Office in New Mexico, and BLM's Tuscarora Field Office in Nevada. The focus of the case studies was on practical applications of nonmarket valuation. USGS worked directly with BLM field staff at the pilot sites to demonstrate the process of considering nonmarket values in BLM decision making and document the questions, challenges, and opportunities that arise when tying economic language to projects. As part of this effort, a Web-based toolkit, available at https://my.usgs.gov/benefit-transfer/, was updated and expanded to help facilitate benefit transfers (that is, the use of existing economic data to quantify nonmarket values) and qualitative discussions of nonmarket values. A total of 53 new or overlooked nonmarket valuation studies comprising 494 nonmarket value estimates for various recreational activities and the preservation of threatened, endangered, and rare species were added to existing databases within this Benefit Transfer Toolkit. In addition, four meta-regression functions focused on hunting, wildlife viewing, fishing, and trail use recreation were developed and added to the Benefit Transfer Toolkit. Results of this effort demonstrate that there are two main roles for nonmarket valuation in BLM planning. The first is to improve the decisionmaking process by contributing to a more comprehensive comparison of economic benefits and cost when evaluating resource tradeoffs for National Environmental Policy Act analyses. The second is to use economic language and information on economic values, either qualitative or quantitative, to improve the ability to communicate the economic significance of the resources provided by BLM-managed lands. Findings also indicate that the use of existing economic data to quantify nonmarket values (that is, benefit transfer) poses unique challenges because of the scarcity of both resource data and existing valuation studies focused on resources and sites managed by BLM. This highlights the need for improvements in the collection of resource data at BLM sites, especially visitor use data, as well as an opportunity for BLM's Socioeconomics Program to strategically identify priority areas, in terms of both resources and geographic locations, where primary valuation studies could be conducted and the results used for future benefit transfers. Finally, whereas qualitative discussions of nonmarket values do not facilitate the comparison of monetized values, they can provide a manageable next step forward in providing more comprehensive information on nonmarket values for BLM plans and project assessments.

We used generalized additive models and geostatistics to identify the range of glacier runoff influence into coastal waters within fjords of varying estuarine influence and topographic complexity. We also modeled the response of depth-integrated chlorophyll a concentration, copepod biomass, fish and seabird abundance to physical, nutrient and biotic predictor variables. The effects of glacial runoff were traced at least 10 km into coastal fjords by cold, turbid, stratified and generally nutrient-rich near-surface conditions. Glacially modified physical gradients, nutrient availability and among-fjord differences explained 67% of the variation in phytoplankton abundance, which is a driver of ecosystem structure at higher trophic levels. Copepod, euphausiid, fish and seabird distribution and abundance were related to environmental gradients that could be traced to glacial freshwater input, particularly turbidity and temperature. Seabird density was predicted by prey availability and silicate concentrations, which may be a proxy for upwelling areas where this nutrient is in excess. Similarities in ecosystem structure among fjords were attributable to an influx of cold, fresh and sediment-laden water, whereas differences were likely related to fjord topography and local differences in estuarine vs. ocean influence. We anticipate that continued changes in the timing and volume of glacial runoff will ultimately alter coastal ecosystems in the future.

Yet due to their sedentary existence, infauna are vulnerable to perturbation and contaminant exposure because they are unable to escape disturbance events. While multiple deep-sea coral habitats were injured by the 2010 Deepwater Horizon(DWH) oil spill, the extent of adverse effects on coral-associated sediment communities is unknown. In 2011, sediments were collected adjacent to several coral habitats located 6 to 183 km from the wellhead in order to quantify the extent of impact of the DWH spill on infaunal communities. Higher variance in macrofaunal abundance and diversity, and different community structure (higher multivariate dispersion) were associated with elevated hydrocarbon concentrations and contaminants at sites closest to the wellhead (MC294, MC297, and MC344), consistent with impacts from the spill. In contrast, variance in meiofaunal diversity was not significantly related to distance from the wellhead and no other community metric (e.g. density or multivariate dispersion) was correlated with contaminants or hydrocarbon concentrations. Concentrations of polycyclic aromatic hydrocarbons (PAH) provided the best statistical explanation for observed macrofaunal community structure, while depth and presence of fine-grained mud best explained meiofaunal community patterns. Impacts associated with contaminants from the DWH spill resulted in a patchwork pattern of infaunal community composition, diversity, and abundance, highlighting the role of variability as an indicator of disturbance. These data represent a useful baseline for tracking post-spill recovery of these deep-sea communities.

The measurements were motivated by recognition that such internal processes (for example, solute benthic flux, bioturbation and solute efflux by benthic invertebrates, and physical groundwater-surface water interactions) were not integrated into existing management models for UKL. Up until 2013, all of the benthic-flux studies generally had been limited spatially to a number of sites in the northern part of UKL and limited temporally to 2-3 samplings per year. All of the benthic invertebrate studies also had been limited to the northern part of the lake; however, intensive temporal (weekly) studies had previously been completed independent of benthic-flux studies. Therefore, knowledge of both the spatial and temporal variability in benthic flux and benthic invertebrate distributions for the entire lake was lacking. To address these limitations, we completed a lakewide spatial study during 2013 and a coordinated temporal study with weekly sampling of benthic flux and benthic invertebrates during 2014. Field design of the spatially focused study in 2013 involved 21 sites sampled three times as the summer cyanobacterial bloom developed (that is, May 23, June 13, and July 3, 2013). Results of the 27-week, temporally focused study of one site in 2014 were summarized and partitioned into three periods (referred to herein as pre-bloom, bloom and post-bloom periods), each period involving 9 weeks of profiler deployments, water column and benthic sampling. Partitioning of the pre-bloom, bloom, and post-bloom periods were based on water-column chlorophyll concentrations and involved the following date intervals, respectively: April 15 through June 10, June 17 through August 13, and August 20 through October 16, 2014. To examine dissolved-solute (0.2-micrometer [mu m] filtered) benthic flux, sets of nonmetallic pore-water profilers (U. S. Patent 8,051,727 B1) were deployed. In 2013, the deployment of profilers at 21 UKL sites occurred at the beginning of the annual cyanobacterial bloom of Aphanizomenon flos-aquae (AFA), in the middle of the bloom period, and at the peak of the bloom. Coordinated benthic invertebrate collections also were made. Based on results from 2013, weekly deployments of profilers and collection of benthic invertebrate samples from late spring to early autumn were used to estimate temporal trends in solute flux and benthic invertebrate densities. Estimates of nutrient efflux by benthic invertebrates were determined in the spring and autumn from 2011 through 2013 and three times (spring, summer, and autumn) in 2015. This work extends UKL studies that began in 2006 to quantify the importance of benthic solute sources in the lake. In 2015, piezometers and thermistor sets were deployed to quantify potential groundwater exchange with the lake water column. Analysis of the 2013 soluble reactive phosphorus (SRP) benthic flux indicated no effect of location (lake region), habitat, or sampling period, and the average lakewide flux values were consistent with earlier studies that had been confined to the northern region of UKL and adjacent wetlands. The 2014 study therefore focused on estimating temporal trends at a site within Ball Bay. During both 2013 and 2014 field studies, fluxes of macronutrients (soluble reactive phosphorus (SRP) and ammonia) and micronutrients (iron [Fe] and manganese [Mn]) were consistently positive and increased prior to the initial AFA bloom, varied or lagged with water-column chlorophyll during the summer bloom period, then decreased after the cyanobacterial blooms, only to rebound toward pre-bloom conditions in the final weeks of sampling. These four solutes exhibited benthic loads greater than maximum riverine loads estimated during the spring and early summers of 2013 and 2014. However, consistently detectable concentrations for all four solutes provide no evidence that they consistently serve as the limiting nutrient for primary production in the lake. In contrast to the four solutes (SRP, ammonia, Fe, and Mn), benthic fluxes of dissolved arsenic (As) were both negative and positive (that is, the lakebed currently serves as both a source and a sink for dissolved As, depending on season). In a further contrast with SRP, ammonia, dissolved Fe, and Mn, dissolved-As riverine loads to UKL were of similar magnitude to benthic loads. A negative relationship between dissolved-As flux and water-column As over the 2014 temporal study provides a potential advantage for the management of water-quality in contrast to solutes, like SRP or ammonia, with consistently positive flux.

These are the most extensive and prominent geomorphic features in the landscape. On this field trip, we will explore the Quaternary evolution of these Front Range features, in addition to viewing the smaller erosion scars and deposits associated with a 1000-yr precipitation event in 2013. We begin the trip near Golden, Colorado, where we will view the most extensive Quaternary strath terrace (Rocky Flats) preserved in the Denver Basin. We then head to Boulder, Colorado, to view the contrast between recent debris flows and deep-seated Quaternary landslides. Near Lefthand Creek, north of Boulder, we will view a suite of strath terraces and discuss the cosmogenic radionuclide dates that indicate both rapid incision and a new version of the terraces ages. Throughout the day, we will focus on the geomorphic work done by rare events, as well as discuss numeric and relative dating of Quaternary terraces and landslides.

The model was calibrated and validated with lake temperature data collected from 1994 to 2011. Wind and air temperature data from three general circulation models and two representative concentration pathways were used to simulate the change in lake temperature and the frequency of deep ventilation events in possible future climates. The lumped model air2water was used to project lake surface temperature, a required boundary condition for the lake model, based on air temperature in the future climates. The 1DDV model was used to simulate daily water temperature profiles through 2099. All future climate scenarios projected increased water temperature throughout the water column and a substantive reduction in the frequency of deep ventilation events. The least extreme scenario projected the frequency of deep ventilation events to decrease from about 1 in 2 years in current conditions to about 1 in 3 years by 2100. The most extreme scenario considered projected the frequency of deep ventilation events to be about 1 in 7.7 years by 2100. All scenarios predicted that the temperature of the entire water column will be greater than 4 degrees C for increasing lengths of time in the future and that the conditions required for thermobaric instability induced mixing will become rare or non-existent. The disruption of deep ventilation by itself does not provide a complete picture of the potential ecological and water quality consequences of warming climate to Crater Lake. Estimating the effect of warming climate on deep water oxygen depletion and water clarity will require careful modeling studies to combine the physical mixing processes affected by the atmosphere with the multitude of factors affecting the growth of algae and corresponding water clarity.

This paper analyzes the extent to which contributions of the wettest days to overall precipitation dictate the state's precipitation seasonality and frequent multiyear periods of drought (as precipitation deficit) and plenty is analyzed, historically and in projections of future climates. The wettest 5% of wet days in California contribute about a third of precipitation but about two-thirds of the variance of water-year precipitation. Yearto- year fluctuations in precipitation strongly reflect year-to-year fluctuations of contributions from the largest storms, with the large-storm contributions explaining about twice as much precipitation fluctuation as do contributions from all remaining storms combined. This extreme dominance of large storms is largely unique to California within the United States. In climate-change projections, eight of ten climate models considered here yield increases in precipitation from the largest storms, and when the increases are large, total precipitation follows suit. All of the models project declines in contributions from the smaller storms and models projecting totalprecipitation declines reflect this decline. Projected changes in variance of water-year precipitation reflect changes in variance of large-storm contributions. The disproportionately large overall contributions from California's largest storms, and their outsized year-to-year variability, ensure that the state's largest storms dictate the state's regimes of wet and dry spells, historically and in climate-change projections.

Although scientific knowledge and understanding of the dynamics and drivers of river-floodplain systems can provide guidance to floodplain managers, the scientific process often occurs in isolation from management. Further, communication barriers between scientists and managers can be obstacles to appropriate application of scientific knowledge. With the coproduction of science in mind, our objectives were the following: (1) to document management priorities of floodplain conservation lands, and (2) identify science needs required to better manage the identified management priorities under nonstationary conditions, i.e., climate change, through stakeholder queries and interactions. We conducted an online survey with 80 resource managers of floodplain conservation lands along the Upper and Middle Mississippi River and Lower Missouri River, USA, to evaluate management priority, management intensity, and available scientific information for management objectives and conservation targets. Management objectives with the least information available relative to priority included controlling invasive species, maintaining respectful relationships with neighbors, and managing native, nongame species. Conservation targets with the least information available to manage relative to management priority included pollinators, marsh birds, reptiles, and shore birds. A follow-up workshop and survey focused on clarifying science needs to achieve management objectives under nonstationary conditions. Managers agreed that metrics of inundation, including depth and extent of inundation, and frequency, duration, and timing of inundation would be the most useful metrics for management of floodplain conservation lands with multiple objectives. This assessment provides guidance for developing relevant and accessible science products to inform management of highly dynamic floodplain environments. Although the problems facing managers of these lands are complex, products focused on a small suite of inundation metrics were determined to be the most useful to guide the decision making process.

In response to these changes, studies concerning indigenous knowledge (IK) and climate change vulnerability, resiliency, and adaptation have increased dramatically in recent years. Risks to lives and livelihoods are often the focus of adaptation research; however, the cultural dimensions of climate change are equally important because cultural dimensions inform perceptions of risk. Furthermore, many Arctic and Subarctic IK climate change studies document observations of change and knowledge of the elders and older generations in a community, but few include the perspectives of the younger population. These observations by elders and older generations form a historical baseline record of weather and climate observations in these regions. However, many indigenous Arctic and Subarctic communities are composed of primarily younger residents. We focused on the differences in the cultural dimensions of climate change found between young adults and elders. We outlined the findings from interviews conducted in four indigenous communities in Subarctic Alaska. The findings revealed that (1) intergenerational observations of change were common among interview participants in all four communities, (2) older generations observed more overall change than younger generations interviewed by us, and (3) how change was perceived varied between generations. We defined "observations" as the specific examples of environmental and weather change that were described, whereas "perceptions" referred to the manner in which these observations of change were understood and contextualized by the interview participants.

Although dive profile analyses obtained using time-depth loggers have provided some insights into habitat use, recent work has shown that more fine-scale monitoring of body movements is needed to elucidate physical activity patterns. We monitored 11 juvenile green sea turtles with tri-axial acceleration data loggers in their foraging grounds in Dry Tortugas National Park, Florida, USA, for periods ranging from 43 to 118 h (mean + or - SD: 72.8 + or - 27.3 h). Approximately half of the individuals (n = 5) remained in shallow (overall mean depth <2 m) water throughout the experiment, whereas the remaining individuals (n = 6) made excursions to deeper (4 to 27 m) waters, often at night. Despite these differences in depth use, acceleration data revealed a consistent pattern of diurnal activity and nocturnal resting in most individuals. Nocturnal depth differences thus do not appear to represent differences in behavior, but rather different strategies to achieve the same behavior: rest. We calculated overall dynamic body acceleration (ODBA) to assess the relative energetic cost of each behavioral strategy in an attempt to explain the differences between them. Animals in deeper water experienced longer resting dives, more time resting per hour, and lower mean hourly ODBA. These results suggest that resting in deeper water provides energetic benefits that outweigh the costs of transiting to deep water and a potential increased risk of predation.

These features were only recently discovered and researched at the Mount Baldy Dune, a rapidly migrating parabolic coastal dune in the Indiana Dunes National Lakeshore. Early research indicates that saprotrophic wood decay fungi (genus Lepiota) continue to actively decompose oak (Quercus spp.) trees after burial and facilitate the biomineralization of a calcium carbonate-rich cement at the contact between the organic material and surrounding siliciclastic sands. The carbonate-rich cement offers temporary stability allowing for open voids to persist for hours to days after the organic debris collapses. Geophysical analysis of Mount Baldy was conducted to determine the relation between the distribution of observed decomposition chimneys and an Inceptisol, now exposed on the stoss slope due to ongoing dune migration. Analyses included 11 km of multi-spectral ground penetrating radar (GPR) collected along transects oriented longitudinal to the direction of dune movement. Numerous hyperbolas are visible in the GPR reflections from the foreset beds and are interpreted as reflections off buried tree limbs and trunks. The collapse features are occurring at the modern surface in an area directly above a roughly east-west oriented limb of a relict, low-relief parabolic dune. Sands overlying the paleosol associated with the buried dune, and encasing modern trees rooted in that surface, are generally less than 5-6 m in thickness. Aerial photographs constrain the timing of dune migration and indicate that the entire process of burial, cementation, organic decomposition, and collapse occurred within 70-100 years at Mount Baldy. While tree casts and rhizocretions may be considered common in calcareous eolianites, the sands of Mount Baldy and coastal dunes of Indiana are dominated by quartz ( approximately 70%) that have lesser amounts of dolomite (<15%) and K-feldspar ( approximately 10%) as estimated by SEM analysis. Ongoing research is evaluating evidence that infiltrating carbonate-rich precipitation is contributing to the development of decomposition chimneys in dunes dominated by siliciclastic sediments.

AN - 1819142910; PQ0003636326 AB - Understanding how climate change may facilitate species turnover is an important step in identifying potential conservation strategies. We used data from 33 sites in western Montana to quantify climate associations with native bull trout (Salvelinus confluentus) and non-native brown trout (Salmo trutta) abundance and population growth rates ( lambda ). We estimated lambda using exponential growth state-space models and delineated study sites based on bull trout use for either spawning and rearing (SR) or foraging, migrating, and overwintering (FMO) habitat. Bull trout abundance was negatively associated with mean August stream temperatures within SR habitat (r = -0.75). Brown trout abundance was generally highest at temperatures between 12 and 14 degree C. We found bull trout lambda were generally stable at sites with mean August temperature below 10 degree C but significantly decreasing, rare, or extirpated at 58% of the sites with temperatures exceeding 10 degree C. Brown trout lambda were highest in SR and sites with temperatures exceeding 12 degree C. Declining bull trout lambda at sites where brown trout were absent suggest brown trout are likely replacing bull trout in a warming climate.Original Abstract: Il importe de comprendre comment le climat pourrait faciliter le renouvellement des especes pour cerner des strategies de conservation potentielles. Nous avons utilise des donnees de 33 sites de l'ouest du Montana pour quantifier les associations climatiques avec l'abondance et les taux de croissance de populations ( lambda ) d'ombles a tete plate (Salvelinus confluentus) indigenes et de truites brunes (Salmo trutta) non indigenes. Nous avons estime lambda en utilisant des modeles d'espaces d'etats de croissance exponentielle et delimite les sites etudies selon leur utilisation par l'omble a tete plate soit comme habitat de frai et d'alevinage (SR) ou d'approvisionnement, de migration et d'hivernage (FMO). L'abondance des ombles a tete plate etait negativement associee aux temperatures moyennes des cours d'eau en aout dans les habitats SR (r = -0,75). L'abondance de la truite brune etait generalement maximum a des temperatures entre 12 et 14 degree C. Nous avons constate que les lambda des ombles a tete plate etaient generalement stables aux sites presentant une temperature moyenne en aout inferieure a 10 degree C, mais qu'il diminuait significativement, l'espece y etant rare ou disparue, dans 58 % des sites ou cette temperature depasse 10 degree C. Les lambda des truites brunes etaient maximums dans les habitats SR et les sites caracterises par des temperatures superieures a 12 degree C. Des lambda en baisse des ombles a tete plate dans des sites exempts de truites brunes donnent a penser que ces dernieres remplacent probablement les ombles a tete plate dans un climat en rechauffement.

Inland capture fisheries and aquaculture contribute over 40% to the world's reported finfish production from less than 0.01% of the total volume of water on earth. These fisheries provide food for billions and livelihoods for millions of people worldwide. Herein, using supporting evidence from the literature, we review 10 reasons why inland fish and fisheries are important to the individual (food security, economic security, empowerment), to society (cultural services, recreational services, human health and well-being, knowledge transfer and capacity building), and to the environment (ecosystem function and biodiversity, as aquatic "canaries", the "green food" movement). However, the current limitations to valuing the services provided by inland fish and fisheries make comparison with other water resource users extremely difficult. This list can serve to demonstrate the importance of inland fish and fisheries, a necessary first step to better incorporating them into agriculture, land-use, and water resource planning, where they are currently often underappreciated or ignored.Original Abstract: Bien que la capture de poissons rapportee par les pecheries soit dominee par la production marine, les poissons et les pecheries de l'interieur des terres apportent des contributions substantielles pour rencontrer les defis rencontres par les individus, les societes et l'environnement dans un paysage en changement global. Les captures des pecheries de l'interieur et l'aquaculture contribuent a la hauteur de 40 % a la production mondiale rapportee pour les poissons a nageoires, a partir de moins de 0,01 % du volume total de l'eau sur terre. Ces pecheries fournissent de la nourriture pour des milliards et un moyen de subsistance pour des millions de gens, partout au monde. Dans cette revue, en utilisant des preuves venant de la litterature, les auteurs examinent 10 raisons pour lesquelles, les pecheries et les poissons de l'interieur sont importants pour les individus (securite alimentaire, securite economique, l'autonomisation), pour la societe (services culturels, services recreatifs, sante humaine et bien-etre, transfert de connaissances et capacite a construire) et pour l'environnement (fonction ecosystemique et biodiversite, comme > aquatiques, pour le mouvement >). Cependant, les limitations actuelles pour evaluer les services fournis par les poissons et les pecheries interieures rendent les comparaisons avec les autres utilisateurs de la ressource en eau extremement difficile. Cette liste peut servir a demontrer l'importance des poissons et des pecheries de l'interieur, une premiere etape essentielle pour mieux les incorporer avec l'agriculture, l'utilisation du territoire et la planification des ressources en eau, ou elles sont actuellement sous-estimees, voire totalement ignorees.

We examined the importance of these glaciers to the basin's summer water balance using an empirical approach. In 1959 approximately 396 glaciers covered 170.23 + or - 8.50 km super(2) of the basin. Since then, combined glacier area has decreased by 32.02 + or - 1.60 km super(2)(- 19%), with most of the loss between elevations of 1600 m and 2100 m. Fifty years ago surface melting of snow, firn, and ice from Skagit glaciers provided from 0.440 + or - 0.055 to 0.742 + or - 0.093 km super(3) of water in summer (May through September) to the Skagit River at Concrete. Today, the surface melt component has decreased (- 24% + or - 9%) and now ranges from 0.333 + or - 0.042 km super(3) of water in cool-wet years to 0.559 + or - 0.070 km super(3) in warm-dry years. Surface melt from the remaining glaciers continues to provide 6-12% of the river's total summer runoff, and roughly twice that fraction during August and September. Cold glacial meltwater is concentrated in tributaries Thunder Creek, White Chuck River, Suiattle River, Baker River, and Cascade River. Between 1959 and 2009 average cumulative annual mass balance of five monitored glaciers was -20.35 + or - 3.63 m water equivalent. This has resulted in glacial water volume loss of 3.01 + or - 0.69 km super(3) basin-wide, representing the elimination of ~ 100 years of fresh water supply for Skagit County at the current rate of consumption.

AN - 1815667892; 2016-076381 AB - Cyclic seafloor wave loading associated with the 1969 passage of Hurricane Camille triggered subaqueous mudslides across the Mississippi River delta front (MRDF), which caused the destruction of several offshore oil platforms. Subsequent geophysical and geotechnical studies of the MRDF found that the delta front is prone to mass failures on gentle gradients (<0.5 degrees ) due to (1) high rates of fine-grained sedimentation and associated underconsolidation, (2) excess sediment pore pressure due to in-situ biogenic gas production, and (3) the frequent passage of tropical cyclones. Most MRDF geohazards research to date has focused on hurricane-triggered mass failures. We seek to test the hypothesis that MRDF seafloor instability is intrinsically linked to major hurricane events. Three spatially overlapping bathymetric datasets were utilized: (1) October 2005 (J.P. Walsh, East Carolina University), (2) February 2009 (Fugro Geoservices, Inc.), and (3) June 2014 (Louisiana State University, Bureau of Ocean Energy Management, and University of New Orleans). Resultant bathymetric digital elevation models (DEMs) were delineated into one of three geomorphic facies, based on elevation relative to the regional trend: gully (bathymetric depression), lobe (bathymetric rise), and undisturbed seafloor. Comparison of facies classification between datasets indicates the seafloor "footprints" of gullies and lobes are relatively stable between surveys, with downslope lobe progradation and gully widening via sidewall failure generally limited to < 100 m/5 years. However, vertical surface differencing of the DEMs shows elevation change of up to 5 meters between surveys ( approximately 1 m/year), most of which is confined to the gully/lobe complexes. Deepening is generally associated with the shallow (20-50 m) reaches of the gullies, while accretion mostly occurs in deeper (50-80 m) water depths. These results indicate that although massive seafloor changes probably do not occur without major hurricane forcing, the MRDF is not in an equilibrium state of no net seafloor movement on a yearly timescale. Knowledge regarding regional seafloor movement is important as the MRDF enters the declining phase of the deltaic cycle; this effort represents a first step towards a MRDF seafloor stability monitoring program.

Sediment cores were collected at continental-shelf sites of the Northern Gulf of Mexico to develop a better understanding of mud-capped dredge pit post-dredging evolution. The two pits studied were Sandy Point (SP) and Raccoon Island (RI) (both at shelf depths of approximately 10m), which were dredged in 2012 and 2013 respectively; vibracores and multicores were collected in 2015. The cores were processed using a multi-sensor whole core logger and analyzed for Beryllium-7 penetration. Whole-core logger data showed discrete packages of less dense sediment (mud) overlaying denser (sandy) sediment. The infill was as thick as 2.3 m. Radioisotope analysis confirmed the extent of recent sediment deposition. At SP, (super 7) Be penetration depths ranged from 12-34 cm, with SP2, the most central site, showing greatest accumulation. In RI multicores, (super 7) Be penetration depths varied from 36 - >50 cm, indicating that (super 7) Be occurred deeper than the 50 cm long multicore. Surface sediment samples from outside the pit contained no (super 7) Be. Of note is the surprising rate of deposition within the pits as well as the source of the infill material. Sediments laden with (super 7) Be must have been deposited within approximately 1-3 half lives of (super 7) Be ( approximately 50-150 days) prior to sampling, indicating recent sedimentation rates greater than 26-50 cm/year. The nearest major sources of river sediment are: 12.5 km offshore from Grand Pass of the Mississippi River for SP; and 147 km from the Mississippi and 65 km from the Atchafalaya River for RI. Because rivers are a major source of (super 7) Be in coastal marine sediments, 26-50 cm of (super 7) Be activity indicates rapid and long-distance transport of sediment from a likely fluvial source and suggests that the pits are efficient sediment traps. An alternative hypothesis would be that marine sediment accumulated and efficiently scavenged (super 7) Be from marine and atmospheric sources. Regardless of source, the dredge pits are accumulating a record of sediment that would not be recorded on the shelf otherwise, and collapses of pit walls cannot explain the whole depositional process. Elucidating this record will be the focus of future study.

High sedimentation rates result in underconsolidation, slope steepening, and increased biogenic gas production, which are all known to decrease stability. Sedimentation rates are highly variable across the MRDF, but are highest near the mouth of Southwest Pass. Previous work has shown that sedimentation rates near Southwest Pass can exceed 1 m/yr with distributary mouth bar progradation at >70 m/yr (between 1764-1979). However, since the 1950s, the suspended sediment load of the Mississippi River has decreased by approximately 50% due to dam construction upstream. In order to examine the impact of this decreased sediment load on subaqueous delta sedimentation patterns and mudflow dynamics, we compiled bathymetric datasets, including historical charts, industry and academic surveys, and NOAA data, collected between 1764 and 2009. Analyses of these datasets show significant changes to delta front growth during the last century. Progradation of Southwest Pass (measured at 10 m depth contour) has slowed from approximately 67 m/yr between 1764 and 1940 to approximately 26 m/yr between 1940 and 1979, with evidence of further deceleration from 1979-2009. The 10 m contour at both South Pass and Pass A Loutre has begun retreating at rates >20 m/yr between 1979-2009. The data reveal that advancement of the delta also decelerated in deeper water across many areas of the delta front. Furthermore, over the area offshore from Southwest Pass, the sediment accumulation rate decreased by approximately 82% between 1940-1979 and 1979-2005. The subaqueous delta front appears to be entering a phase of decline, and we expect these sedimentation trends to impact the spatial and temporal patterns of subaqueous mudflows. Nevertheless, despite the decreased sediment input and accumulation, we still observe advancement of some mudflow lobes during the past approximately 30 years, and mudflows have recently been documented associated with Hurricanes Ivan (2004) and Katrina (2005). New geophysical and sedimentological data will be required to assess potential mudflow hazards associated with changing sedimentation rates and patterns.

Discrete sand deposits associated with ancient rivers that incised the shelf during lower sea-level positions occur close to shore. These shelf channel sands have been targeted for coastal restoration projects resulting in significant cost savings over more distal deposits. Several recent projects targeted shelf paleo-fluvial deposits comprising relatively deep (10 m) channel sands underlying a muddy overburden. Because of contrasting characteristics of cohesive mud vs. non-cohesive sand and potential modern fluvial mud supply from the Mississippi and Atchafalaya River, long term pit evolution is poorly understood relative to their more common sand-only counterparts. Alterations to seafloor topography from dredging shelf sediment resources can potentially affect oil and gas infrastructure or other resources of concern (i.e. historic shipwrecks) located proximal to dredge pits. Site-specific data required to make accurate predictions and empirical measurements to test and validate predictive models were only available for Peveto Channel offshore Holly Beach, Louisiana. Here we present new geophysical and geological data (bathymetry, sidescan, subbottom, and radionuclide of sediment cores) and physical oceanographic observations (hydrodynamics and sediment dynamics) collected at Raccoon Island (dredged in 2013) dredge pit in Louisiana. These field data collections along with pre-existing data provide a time-series to capture evolution at Raccoon Island post-excavation. Conceptual morphological models will be developed for dredge pit evolution and testing effectiveness of setback buffers protecting pipelines, habitats, and cultural resources. Our results will increase decision making ability regarding safety and protecting environmental and cultural resources, and better management of valuable sand resources.

This fossil was recovered from 60 m below the surface of a cenote (a water-filled karstic sinkhole). Cathodoluminescence (CL) microscopy was used to identify post-depositional chemical and mineralogical diagenesis accompanying fossilization. CL employs electron beam bombardment to stimulate visible light emission from the minerals comprising the fossilized tooth based on the major and minor element composition. Thus, CL analysis enables the user to identify diagenetic mineral recrystallization and replacement of the three major tissue types in sloth teeth: orthodentine, vasodentine and cementum. Results from CL analysis demonstrate that orthodentine, which is the least porous tissue type, is most resistant to alteration. Cracks in orthodentine cemented with diagenetic calcite crystals were avoided during sampling for radiocarbon dating and stable isotopic analyses. Twenty bioapatite microsamples (5-15 mg) were drilled from the orthodentine along 8.5 cm of the growth axis of the tooth. The results of isotopic analyses (delta (super 13) C: -9.1 to -10.9 ppm; delta (super 18) O: 26.9 to 29.1 ppm) establish a pattern of covariance that reflects moderate seasonal variation in stomatal conductance and evapotranspirative water stress of the C (sub 3) plants that this sloth consumed at the end of the last Ice Age. This giant ground sloth, standing 6m tall, likely climbed down the steep sides of the cenote for a drink during a particularly arid period, became trapped, died and was fossilized; its remains were recovered by divers thousands of years later.

Stratigraphic descriptions, soil profiles and radiocarbon dating of alluvial deposits combined with two-dimensional hydraulic modeling were utilized to refine extreme flood magnitude and frequency estimates on the South Fork Boise River and Middle Fork Boise River. Results indicate that extreme floods are larger in magnitude on the Middle Fork than on the South Fork Boise River. This conclusion is supported by the historical gaging record and the soil/stratigraphic record. The hydraulic models show that stream terraces along the South Fork Boise River are inundated by approximately half the discharge magnitude than stream terraces of comparable age on the Middle Fork Boise River even though the sites have similar drainage areas. The largest historical floods recorded by those stream gages also show that larger magnitude floods have occurred on the Middle Fork Boise River relative to the South Fork Boise River when comparing unregulated records from stream gages in the basin. For example, the peaks of record on the South Fork Boise River near Lenox, ID and Featherville, ID are either closely matched or exceeded by the peaks for the same date on the Middle Fork Boise River near Twin Springs, ID. Furthermore, the peak of record as well as several other large historical peaks on the Middle Fork Boise River near Twin Springs, ID far exceed any peak discharge recorded on the South Fork Boise River, by about 1.5 to >2 times. We evaluate several factors that could explain the differences, including the position of storm tracks, basin physiography, and basin shape and aspect. The results highlight differences in extreme flood potential between adjacent basins and indicate that the differences in basin response are related to enduring physical characteristics of the basins and are not a product of a biased, short-term systematic record.

Our preliminary results present a conundrum: although all deposits are geomorphically young (fresh unweathered boulders, unstable and unvegetated slopes) and were previously mapped as Matthes age (Little Ice Age (LIA) equivalent), only some moraines show dominantly young ages consistent with the mapping and other previous studies of Neoglaciation in the range. In contrast, some of the moraines show a majority of ages thousands of years older than LIA. For example, nearly all (super 10) Be ages on Matthes moraines below the Lyell Glacier (Yosemite NP) lie between 150-300 yr before 2015, whereas similar moraines below the adjacent Maclure Glacier have exposure ages ranging from 1900-3900 yr old. Boulders on correlative Matthes moraines to the north below Price Peak (west Lake Tahoe) have exposure ages ranging from 1900-9900 yr old, with no ages within the LIA window. The abundance of preLIA exposure ages on many of these moraines seemingly contradicts both historical photographic evidence as well as geomorphic and lake sediment evidence, which indicate that the most extensive Holocene glaciation in the Sierra Nevada was during the late LIA. Although inheritance in moraines of such small glaciers likely explains some of the discrepancy, internal consistency of ages at some sites belies that as the sole reason. Some ages, such as those below the Maclure Glacier, may reflect slow flow dynamics associated with debris covered glaciers (rock glaciers). The older ages below Price Peak, however, are more difficult to reconcile with previous studies, particularly those indicating absence of glaciers in the Sierra before approximately 3500 cal yr BP. Other possible explanations include deposition related to protalus processes or to discrete events (e.g., earthquake induced rockfall); conversely, the ages may indicate that Holocene glaciation in the range was more spatially and temporally heterogeneous than previously thought. CRN analyses of the remainder of the samples, as well as planned lake-sediment coring below select sites, may help resolve this conundrum.

Varves from glacial Lake Agassiz found within lakes from northern Minnesota (MN) and northwestern Ontario (ON) should archive a 3000+ year record of ice sheet response from the mid-continent of the LIS, spanning from the Bolling-Allerod through the Younger Dryas (YD). Here we present Lake Agassiz stratigraphic and varve thickness data from Lake Kabetogama (MN) sediment cores. Lake Kabetogama is the oldest of three varve series from the region, which includes Steep Rock Lake (ON) and multiple sites from Lake Wabigoon (ON). Sediments from all three can be correlated with a series of approximately 24 anomalously thick red clay varves, previously interpreted to have resulted from the western flow of red Lake Superior sediments into the Lake Agassiz basin due to ice re-advance to the Marks and Dog Lake moraines, presumably near the end of the YD. Macrofossils within the Lake Kabetogama sediments should provide the first radiocarbon dates of this event. The oldest glaciolacustrine sediments in Kabetogama consist of 523 varves that record ice retreat from the core site. These varves pre-date the oldest varves at Steep Rock and Wabigoon. The stratigraphy above the 523 basal varves is complex, and includes units of laminated sand and silt, superseded by periods characterized by the abrupt onset of anomalously thick varves that rapidly thin up section. Based on comparisons with other glacial varve sediments, the sand and silt units most likely resulted from lake level lowering. The thick varves could be explained by rapid lake level rise due to ice margin fluctuations closing an eastern Lake Agassiz outlet into the Lake Superior basin (during or before the YD.) Alternatively, the thick varves may reflect a sudden and dramatic increase in sediment flux from the LIS, presumably due to summer melting. Better dating precision would place this varve record, which clearly documents abrupt and short-lived events, in context with high resolution climate records, such as those from the Greenland Ice Sheet.

Along Pope Ck, NW of Lake Berryessa, we also collected sandstone and a thin tuff from strata overlying mafic breccia at the base of the GVS, that in turn, is unconformable on the Coast Range Ophiolite (CRO). Low yield zircon separates from the tuff at Pope Ck and the stratigraphically lowest sandstone at Knoxville (n=10 and 24, respectively) were analyzed at the Stanford/USGS SHRIMP. Zircons from 3 localities at Knoxville (each with n>100) and 1 locality at Pope Ck (n=60), were analyzed at the USGS Denver ICPMS lab. A Knoxville maximum depositional age (MDA) was based on the youngest cluster of 3 or more ages that overlap at 2 sigma (Dickinson and Gehrels, EPSL, 2009); which was compared with the age indicated by the Buchias. The stratigraphically lower 3 localities at Knoxville all contain B. piochii and (or) B. elderensis (Tithonian) and have MDAs of 154.1 + or - 9.9 Ma, 142.0 + or - 13 Ma and 153.6 + or - 2.0 Ma. A 4th locality (stratigraphically highest) contains B. pacifica (Valanginian), with a MDA of 139.6 + or - 2.8 Ma. At Pope Creek, the mean age at, of 4 youngest zircons in the tuff from shale above the basal breccia, is 151.1 + or - 2.5 Ma (1 sigma). The MDA of sandstone downfaulted onto the basal breccia is 142 + or - 1.8 Ma (Berriasian). DZ-derived MDAs of lower GVS strata reasonably match fossil ages. A major change in zircon provenance occurs in our samples in the Early Cretaceous ( approximately 145 -143 Ma), based largely on > or =145 Ma GVS samples having significant Precambrian zircons likely sourced from south of the Sierran arc, that contrast with or = 500 km of Early Cretaceous dextral displacement of the lower GVS from S of the Sierran arc to explain such a change. If our observed provenance change at 145-143 Ma was due to dextral translation, it was bracketed by major CRO unroofing recorded by the basal breccia (> or = 151 Ma), sedimentary serpentinite (134-131 Ma) and later by mixing of the CRO and lower GVS into melange.

To help celebrate, the White House has begun an incredible "Every Kid in a Park" youth initiative to get all 4th graders and their families to experience the places that are home to our country's natural treasures, rich history, and vibrant culture. This also presents a unique opportunity to showcase the paleontological resources of our many National Parks to these young people. Over the past four years, the Florida Paleontological Society (FPS), the Florida Geological Foundation (FGF), and the Florida Fossil Hunters (FFH) have been working with many fossil groups around the state to produce a much needed resource to help the parks in their interpretation and presentation of Florida paleontology. Each year several fossil education kits have been produced, from club resources and member donations. These kits are designed to complement the NPS Junior Ranger Paleontology Program. They highlight the diverse paleontological resources of our national parks, with a special emphasis on local paleontology. So far the kits have been distributed to 11 national park units, mainly in Florida. The earliest kits have been in use and rotation since 2012 and are a major component of each unit's National Fossil Day celebrations. It is our hope that these kits will become an integral part of each park's programming and educational outreach. A survey completed by each park with a Junior Paleontology kit shows that, increasingly, this is the case; we hope to see growth of the program to other regions of the country and expanded outreach opportunities in paleontological education.

A multi-sensor geophysical survey has been initiated to provide a more thorough determination of the shallow geologic framework and bottom habitat and cultural resources potential to further refine future wind farm siting. The study is focused on two areas: the inner shelf from 18 to 26 km offshore of North Myrtle Beach, SC and a second smaller area offshore of Georgetown, SC. The collaborative effort is generating 100% multibeam and side scan sonar coverage and chirp sub-bottom and magnetometer data on 180 meter line spacing. The 10-km wide swath parallels a similar high-resolution geophysical survey from the shoreline to 8 km offshore, from the North Carolina Border to Winyah Bay, completed as part of the joint USGS-SC Sea Grant South Carolina Coastal Erosion Study. Across the region a thin veneer of sediment overlies indurated tertiary deposits. The Tertiary geologic section is locally scoured and influenced by small channels and probable karstification and enduring fluid exchange across the sea floor which has been previously identified in the region. The sea floor exhibits large-scale (100s of meters) low relief shore-perpendicular bedforms similar to those found within the shoreface and innermost shelf through the SC Coastal Erosion Study. Central to the WEA study is the realization that the Outer Continental Shelf (OCS) has the potential to yield a wealth of archaeological information about the early peopling of North America and the historic seafaring traditions of exploration, trade, and warfare. Preliminary project findings suggest that three historic shipwrecks have been located, with on-going efforts to identify paleolandforms bearing the potential to contain evidence of human habitation. Following the initial regional mapping, site-specific groundtruthing will be undertaken in the spring and summer of 2016.

AN - 1808712061; PQ0003376764 AB - We used both stomach content and stable isotope analyses to describe the feeding ecology of Siberian prawns Palaemon modestus(Heller, 1862), a non-native caridean shrimp that is a relatively recent invader of the lower Snake River. Based on identifiable prey in stomachs, the opossum shrimp Neomysis mercedis Holmes, 1896 comprised up to 34-55% (by weight) of diets of juvenile to adult P. modestus, which showed little seasonal variation. Other predominant items/taxa consumed included detritus, amphipods, dipteran larvae, and oligochaetes. Stable isotope analysis supported diet results and also suggested that much of the food consumed by P. modestus that was not identifiable came from benthic sources - predominantly invertebrates of lower trophic levels and detritus. Palaemon modestus consumption of N. mercedis may pose a competitive threat to juvenile salmon and resident fishes which also rely heavily on that prey.

Many of these tailwater fisheries have experienced declines in the abundance and condition of large trout species, yet the causes of these declines remain uncertain. Here, we develop, assess, and apply a drift-foraging bioenergetics model to identify the factors limiting rainbow trout (Oncorhynchus mykiss) growth in a large tailwater. We explored the relative importance of temperature, prey quantity, and prey size by constructing scenarios where these variables, both singly and in combination, were altered. Predicted growth matched empirical mass-at-age estimates, particularly for younger ages, demonstrating that the model accurately describes how current temperature and prey conditions interact to determine rainbow trout growth. Modeling scenarios that artificially inflated prey size and abundance demonstrate that rainbow trout growth is limited by the scarcity of large prey items and overall prey availability. For example, shifting 10% of the prey biomass to the 13 mm (large) length class, without increasing overall prey biomass, increased lifetime maximum mass of rainbow trout by 88%. Additionally, warmer temperatures resulted in lower predicted growth at current and lower levels of prey availability; however, growth was similar across all temperatures at higher levels of prey availability. Climate change will likely alter flow and temperature regimes in large rivers with corresponding changes to invertebrate prey resources used by fish. Broader application of drift-foraging bioenergetics models to build a mechanistic understanding of how changes to habitat conditions and prey resources affect growth of salmonids will benefit management of tailwater fisheries.Original Abstract: Les conditions d'eau froide et claire presentes en aval de nombreux grands barrages creent les conditions ideales pour le developpement de peches aux salmonides d'importance economique. Si bon nombre de ces peches en aval de barrages ont connu des baisses d'abondance et d'embonpoint de grandes especes de truites, les causes de ces baisses demeurent incertaines. Nous elaborons, evaluons et appliquons un modele bioenergetique d'approvisionnement a la derive afin de cerner les facteurs qui limitent la croissance des truites arc-en-ciel (Oncorhynchus mykiss) dans un grand cours d'eau en aval d'un barrage. Nous examinons l'importance relative de la temperature, de la quantite de proies et de la taille des proies en elaborant des scenarios dans lesquels ces variables, individuellement ou combinees, sont modifiees. La croissance predite concorde avec les estimations empiriques du poids selon l'age, particulierement pour les groupes d'ages plus jeunes, ce qui demontre que le modele decrit avec exactitude l'effet de l'interaction de la temperature et des conditions relatives aux proies sur la croissance des truites arc-en-ciel. Des scenarios de modelisation qui gonflent artificiellement la taille et l'abondance des proies demontrent que la croissance des truites arc-en-ciel est limitee par la rarete de grosses proies et la disponibilite globale de proies. Par exemple, le fait de transferer 10 % de la biomasse de proies dans la classe de longueur de 13 mm (grande) sans accroitre la biomasse globale de proies se traduit par une augmentation de 88 % du poids maximum durant la vie des truites arc-en-ciel. En outre, des temperatures plus chaudes se traduisent par une croissance predite plus faible pour un degre de disponibilite de proies egal ou plus faible que le degre actuel; cependant, la croissance est semblable pour toutes les temperatures pour des degres de disponibilite de proies plus eleves. Les changements climatiques modifieront vraisemblablement les regimes d'ecoulement et de temperature dans les grandes rivieres, entrainant des changements correspondants aux ressources de proies invertebrees utilisees par les poissons. L'application elargie de modeles bioenergetiques d'approvisionnement a la derive pour etablir une comprehension mecaniste de l'influence des modifications des conditions de l'habitat et des ressources en proies sur la croissance des salmonides sera utile pour la gestion des peches en aval de barrages.

Here we identify a list of principles, based on a combination of field studies, controlled laboratory experiments, and previously unpublished observations, that govern the epizootiology of VHS in Pacific herring. A thorough understanding of these principles provides the basis for identifying risk factors that predispose certain marine fish populations to VHS epizootics, including the lack of population resistance, presence of chronic viral carriers in a population, copious viral shedding by infected individuals, cool water temperatures, limited water circulation patterns, and gregarious host behavioral patterns. Further, these principles are used to define the epizootiological stages of the disease in Pacific herring, including the susceptible (where susceptible individuals predominate a school or subpopulation), enzootic (where infection prevalence and intensity are often below the limits of reasonable laboratory detection), disease amplification (where infection prevalence and intensity increase rapidly), outbreak (often accompanied by host mortalities with high virus loads and active shedding), recovery (in which the mortality rate and virus load decline owing to an active host immune response), and refractory stages (characterized by little or no susceptibility and where viral clearance occurs in most VHS survivors). In addition to providing a foundation for quantitatively assessing the potential risks of future VHS epizootics in Pacific herring, these principles provide insights into the epizootiology of VHS in other fish communities where susceptible species exist.Original Abstract: Si le virus de la septicemie hemorragique virale (VSHV) est typiquement present a faible prevalence et intensite dans les populations naturelles de hareng du Pacifique (Clupea pallasii) et d'autres poissons marins dans le nord-est de l'ocean Pacifique, des epizooties de la maladie en decoulant (SHV) se produisent periodiquement, souvent associees a des mortalites de poissons observees. Nous presentons une liste de principes, reposant sur une combinaison d'etudes de terrain, d'essais controles en laboratoire et d'observations non publiees, qui regissent l'epizootiologie de la SHV chez le hareng du Pacifique. Une comprehension exhaustive de ces principes fournit les bases qui permettent de cerner les facteurs de risque predisposant certaines populations de poissons marins aux epizooties de SHV, dont l'absence de resistance de la population, la presence de porteurs viraux chroniques dans une population, l'elimination copieuse du virus par des individus infectes, de faibles temperatures de l'eau, une circulation de l'eau limitee et des comportements gregaires des hotes. Ces principes sont en outre utilises pour definir les stades epizootiologiques de la maladie chez le hareng du Pacifique, dont les stades de susceptibilite (ou les individus susceptibles predominent dans un banc ou une sous-population), d'enzootie (ou la prevalence et l'intensite de l'infection sont souvent inferieures aux limites raisonnables de detection en laboratoire), d'amplification de la maladie (ou la prevalence et l'intensite de l'infection augmentent rapidement), d'eclosion (souvent accompagnee d'une mortalite des hotes avec de fortes charges virales et une elimination active), de recuperation (ou le taux de mortalite et la charge virale diminuent en raison de la reaction immunitaire active des hotes) et de refraction (caracterise par une susceptibilite faible a nulle et par la clairance du virus chez la plupart des survivants a la SHV). En plus de fournir les bases de l'evaluation quantitative des risques potentiels d'epizooties futures de SHV chez le hareng du Pacifique, ces principes jettent un nouvel eclairage sur l'epizootiologie de la SHV dans d'autres communautes de poissons comprenant des especes susceptibles.

AN - 1807509297; 2016-067593 AB - The San Andreas Fault (SAF) system in southern CA includes the following elements: (1) the SAF zone, a continental transform that evolved at approximately 6-5 Ma; (2) the coeval West Salton Detachment (WSD) and its supradetachment fill; (3) the Salton Trough that developed as the Gulf of California Transtensional Regime (GCTR) propagated northwestward beginning at approximately 6.3 Ma; (4) the San Jacinto Fault (SJF) that initiated at approximately 1.2 Ma in response to SAF complexities manifested especially in the San Gorgonio Pass (SGP) contractional belt; (5) younger parts of the Eastern CA Shear Zone (ECSZ) that evolved as dextral shear stepped across the Eastern Transverse Ranges (ETR) and its clockwise-rotating panels. All of these events yielded distinctive landscapes, including: the SW-facing Little San Bernardino Mountains escarpment (LSBME); the N boundary of the ETR (Pinto Mountain Fault, PMF); the contractional SGP region; and landscapes on the WSD footwall of the San Jacinto Mts/Santa Rosa Mts block. Critical questions include: (1) Do late Miocene marine rocks in today's SGP represent the onshore head of the GCTR, when SGP landscapes originally were positioned 140+ km to the SE (Matti and Morton, 1993)? (2) Pleistocene contraction in SGP led to overthrusting of low-density materials by crystalline rocks of the SE San Bernardino Mts, presumably including the marine rocks; does this mean that the NW head of the GCTR originally could have extended NW beyond SGP? (3) When and by what mechanism did uplift and exhumation of the LSBM begin (7 Ma according to cooling ages; Sabala, 2010)? Is the timing of LSBME development compatible with that of other landscapes within the distributive SAF system? (4) Did the LSBME originally extend NW of the ETR? (5) if sinistral slip on the PMF is responsible for the E-trending 15 km bend in the Mission Creek Fault in SGP (Matti and Morton, 1993), then most of the PMF's displacement is post 1.2 Ma. Is this compatible with what is known about the PMF as a northern boundary to clockwise-rotating ETR blocks (Powell, 1993)? (6) Where and what are structures in the LSBM that facilitate strain transfer to the ECSZ (Hislop, in progress)? We explore these questions by integrating what is known about geologic, geomorphic, and geochronologic data sets from today's northwest head of the Salton Trough as it evolved during the timeframe 7 Ma-0 Ma.

We re-evaluate Judith River stratigraphy and propose new reference sections that both document the range of lithologies present in the type area in north-central Montana and reveal dramatic changes in facies architecture, fossil content, and rock accumulation rates that can be mapped throughout the type area and into the plains of southern Alberta and Saskatchewan. One section spans the basal contact of the Judith River Formation with marine shales of the underlying Claggett Formation. This contact, which lies along the base of the Parkman Sandstone Member of the Judith River Formation, is erosional and consistent with an episode of forced regression, contrary to previous descriptions. A second reference section spans the entire Judith River Formation. This complete section hosts a lithologic discontinuity, herein referred to as the mid-Judith discontinuity, that reflects a regional reorganization of terrestrial and marine depositional systems associated with a turnaround from regressive to transgressive deposition. The mid-Judith discontinuity correlates with the base of three backstepping marine sequences in the eastern sector of the type area and is thus interpreted as the terrestrial expression of a maximum regressive surface. This mid-Judith discontinuity defines the boundary between the new McClelland Ferry and overlying Coal Ridge Members of the Judith River Formation. The shallow marine sandstones that form the backstepping sequences represent the leading edge of the Bearpaw transgression in this region and are formalized as the new Woodhawk Member of the Judith River Formation in a third reference section. New (super 40) Ar/ (super 39) Ar ages indicate (1) that the mid-Judith discontinuity formed approximately 6.2 Ma, coincident with the onset of the Bearpaw transgression in central Montana; and (2) that the Bearpaw Sea had advanced westward beyond the Judith River type area by approximately 5.2 Ma, on the basis of the dating of a bentonite bed at the base of the Bearpaw Formation. These new ages also provide more confident age control for important vertebrate fossil occurrences in the Judith River Formation. Facies analysis across the mid-Judith discontinuity reveals how alluvial systems respond to regional base-level rise, which is implicit with the increase in rock accumulation rates and marine transgression. With the increase in accommodation signaled by the mid-Judith discontinuity, the alluvial system shifted in dominance from fluvial channel to overbank deposits, with greater tidal influence in channel sands, more hydromorphic and carbonaceous overbank deposits, and a higher frequency of bentonites and skeletal concentrations, suggesting higher preservation rates. These features, along with the appearance of extra formational pebbles above the discontinuity, are consistent with an upstream tectonic explanation for the addition of accommodation.

Permafrost aggradation can control the magnitude of the carbon feedback in peatlands through effects on peat properties. We compiled peatland plant macrofossil records for the northern permafrost zone (515 cores from 280 sites) and classified samples by vegetation type and environmental class (fen, bog, tundra and boreal permafrost, and thawed permafrost). We examined differences in peat properties (bulk density, carbon (C), nitrogen (N) and organic matter content, and C/N ratio) and C accumulation rates among vegetation types and environmental classes. Consequences of permafrost aggradation differed between boreal and tundra biomes, including differences in vegetation composition, C/N ratios, and N content. The vegetation composition of tundra permafrost peatlands was similar to permafrost-free fens, while boreal permafrost peatlands more closely resembled permafrost-free bogs. Nitrogen content in boreal permafrost and thawed permafrost peatlands was significantly lower than in permafrost-free bogs despite similar vegetation types (0.9% versus 1.5% N). Median long-term C accumulation rates were higher in fens (23 g C m (super -2) yr (super -1) ) than in permafrost-free bogs (18 g C m (super -2) yr (super -1) ) and were lowest in boreal permafrost peatlands (14 g C m (super -2) yr (super -1) ). The plant macrofossil record demonstrated transitions from fens to bogs to permafrost peatlands, bogs to fens, permafrost aggradation within fens, and permafrost thaw and reaggradation. Using data synthesis, we have identified predominant peatland successional pathways, changes in vegetation type, peat properties, and C accumulation rates associated with permafrost aggradation.

Basins intercepting the main flow and external P sources had highest P and CHL and shallowest SD. Internal loading in shallow, polymictic basins caused P and CHL to increase and SD to decrease as summer progressed. Winter aeration used to eliminate winterkill increased summer internal P loading and decreased water quality, while reductions in upstream beaver impoundments had little effect on water quality. Variations in air temperature and precipitation affected each basin differently. Warmer air temperatures increased productivity throughout the lake and decreased clarity in less eutrophic basins. Increased precipitation increased P in the basins intercepting the main flow but had little effect on the isolated deep West Bay. These relations are used to project effects of future climatic changes on LSG and other temperate lakes.Original Abstract: Le lac Little St. Germain (LSG), un lac a plusieurs bassins relativement vierge du Wisconsin (Etats-Unis), a ete examine pour determiner l'incidence de facteurs morphologiques (internes), climatiques (externes), humains (aeration hivernale) et naturels (activites des castors) sur l'etat trophique (phosphore, P; chlorophylle, CHL; profondeur de Secchi, SD) de chacun de ses bassins. Les bassins interceptant l'ecoulement principal et les sources externes de P presentaient les P et CHL les plus eleves et la SD la plus faible. La charge interne dans les bassins polymictiques peu profonds entrainait l'augmentation du P et de la CHL et la diminution de la SD au fil de l'ete. En ce qui concerne les mesures de gestion, l'aeration hivernale visant a eliminer la martegade accroissait la charge interne estivale de P et reduisait la qualite de l'eau, alors que les reductions des digues de castors en amont n'avaient que peu d'effet sur cette derniere. L'incidence des variations de la temperature de l'air et des precipitations variait d'un bassin a l'autre. Des temperatures plus chaudes de l'air accroissaient la productivite a la grandeur du lac et reduisaient la clarte dans les bassins moins eutrophes. De plus importantes precipitations se traduisaient par une augmentation du P dans les bassins qui interceptent l'ecoulement principal, mais n'avaient que peu d'effet sur le bassin profond et isole de West Bay. Ces relations sont utilisees pour predire les effets de changements climatiques futurs sur le LSG et d'autres lacs temperes.

Location Thirty-eight thousand nine hundred and seventy hectare of floodplain, spanning 320 km of the Upper Mississippi River (UMR). Methods High-resolution elevation data (Lidar) and 30 yr of daily river stage data were integrated to produce a 'floodscape' map of growing season flood inundation duration. The distributions of 16 different remotely sensed plant communities were quantified along the gradient of flood duration. Results Models fitted to the cumulative frequency of occurrence of different vegetation types as a function of flood duration showed that most types exist along a continuum of flood-related occurrence. The diversity of community types was greatest at high elevations (0-10 d of flooding), where both upland and lowland community types were found, as well as at very low elevations (70-180 d of flooding), where a variety of lowland herbaceous communities were found. Intermediate elevations (20-60 d of flooding) tended to be dominated by floodplain forest and had the lowest diversity of community types. Conclusions Although variation in flood inundation is often considered to be the main driver of spatial patterns in floodplain plant communities, few studies have quantified flood-vegetation relationships at broad scales. Our results can be used to identify targets for restoration of historical hydrological regimes or better anticipate hydro-ecological effects of climate change at broad scales. De Jager et al. develop a simple method to model and map flood inundation within floodplains at large spatial scales. In an application to the Upper Mississippi River floodplain, the authors use maps of the 'floodscape' to explain spatial variation in the distribution of 16 different plant communities. Quantification of flood inundation - vegetation relationships should help to identify targets for vegetation management in floodplains.

We monitored fates of 297 radio-marked Surf Scoters at three study sites: (1) near the northern periphery of their wintering range in southeast Alaska, USA, (2) the range core in British Columbia, Canada, and (3) the southern periphery in Baja California, Mexico. We detected 34 mortalities and determined that survival averaged lower at the range peripheries than in the range core, was lower during mid-winter than during late winter at all sites, and was positively correlated with body mass within locations. Although neither age nor sex class had direct effects, mass effects led to differential survival patterns among classes. When simultaneously incorporating these interacting influences, adult males of mean mass for their location had highest survival at the northern range periphery in Alaska, whereas adult females and juveniles had higher survival at the range core and the southern periphery. Our observations help to explain patterns of differential migration and distribution reported for this species and highlight seasonal periods (mid-winter) and locations (range peripheries) of elevated levels of mortality for demographically important age-sex classes (adult females).Original Abstract: Nous avons quantifie les variations de la survie hivernale des macreuses a front blanc (Melanitta perspicillata (L., 1758)) sur 30 super(o) de latitude le long de la cote pacifique de l'Amerique du Nord afin d'en evaluer les effets potentiels sur la repartition hivernale, dont differentes repartitions observees selon les classes d'age et de sexe. Nous avons surveille le destin de 297 macreuses munies de radioemetteurs dans les trois sites d'etude suivants : (1) pres de la bordure nord de leur aire d'hivernage dans le sud-est de l'Alaska (Etats-Unis), (2) au coeur de leur aire de repartition en Colombie-Britannique (Canada) et (3) a la bordure meridionale de leur aire de repartition, en Basse-Californie (Mexique). Nous avons releve 34 cas de mortalite et determine que la survie moyenne etait plus faible en bordure de l'aire de repartition qu'en son centre, qu'elle etait plus faible au milieu de l'hiver qu'a la fin de l'hiver dans tous les sites, et qu'elle etait possiblement correlee a la masse du corps a l'interieur d'un meme site. Si ni la classe d'age, ni la classe de sexe n'avaient d'effet direct, des effets de la masse entrainaient differents motifs de survie au sein des classes. Quand ces influences interactives etaient incluses simultanement, les males adultes de masse moyenne pour leur emplacement presentaient le taux de survie le plus eleve a la bordure nord de l'aire de repartition en Alaska, alors que les femelles adultes et les juveniles presentaient le plus grand taux de survie au centre de l'aire de repartition et a sa bordure meridionale. Nos observations aident a expliquer les motifs de migration et de repartition differentielles signales pour cette espece et font ressortir des periodes saisonnieres (le milieu de l'hiver) et des lieux (aux bordures de l'aire de repartition) de mortalite elevee pour des classes d'age et de sexe importantes sur le plan demographique (femelles adultes).

However, in the past few decades ecologists have become increasingly interested in the use of Bayesian methods of data analysis. In this article I provide guidance to ecologists who would like to decide whether Bayesian methods can be used to improve their conclusions and predictions. I begin by providing a concise summary of Bayesian methods of analysis, including a comparison of differences between Bayesian and frequentist approaches to inference when using hierarchical models. Next I provide a list of problems where Bayesian methods of analysis may arguably be preferred over frequentist methods. These problems are usually encountered in analyses based on hierarchical models of data. I describe the essentials required for applying modern methods of Bayesian computation, and I use real-world examples to illustrate these methods. I conclude by summarizing what I perceive to be the main strengths and weaknesses of using Bayesian methods to solve ecological inference problems.

One of the core assumptions of SCR models is that individuals possess home ranges that are spatially stationary during the sampling period. For many species, this assumption is unlikely to be met and, even for species that are typically territorial, individuals may disperse or exhibit transience at some life stages. In this paper we first conduct a simulation study to evaluate the robustness of estimators of density under ordinary SCR models when dispersal or transience is present in the population. Then, using both simulated and real data, we demonstrate that such models can easily be described in the BUGS language providing a practical framework for their analysis, which allows us to evaluate movement dynamics of species using capture-recapture data. We find that while estimators of density are extremely robust, even to pathological levels of movement (e.g., complete transience), the estimator of the spatial scale parameter of the encounter probability model is confounded with the dispersal/transience scale parameter. Thus, use of ordinary SCR models to make inferences about density is feasible, but interpretation of SCR model parameters in relation to movement should be avoided. Instead, when movement dynamics are of interest, such dynamics should be parameterized explicitly in the model.

We describe how trout growth rates and condition could be influencing trout population dynamics in a 130 km section of the Colorado River below Glen Canyon Dam based on a large-scale mark-recapture program where 8000 rainbow trout were recaptured over a 3-year period (2012-2014). There were strong temporal and spatial variations in growth in both length and weight as predicted from von Bertalanffy and bioenergetic models, respectively. There was more evidence for seasonal variation in the growth coefficient and annual variation in the asymptotic length. Bioenergetic models showed more variability for growth in weight across seasons and years than across reaches. These patterns were consistent with strong seasonal variation in invertebrate drift and effects of turbidity on foraging efficiency. Highest growth rates and relative condition occurred in downstream reaches with lower trout densities. Results indicate that reduction in rainbow trout abundance in Glen Canyon will likely increase trout size in the tailwater fishery and may reduce downstream dispersal into Grand Canyon.Original Abstract: Les truites arc-en-ciel (Oncorhynchus mykiss) ont ete deliberement introduites dans de nombreuses rivieres regularisees, entrainant des consequences imprevues sur les poissons indigenes. Nous decrivons l'influence potentielle des taux de croissance et de l'embonpoint des truites sur la dynamique de la population de truites dans un troncon de 130 km du fleuve Colorado en aval du Glen Canyon, a la lumiere d'une campagne de marquage-recapture a grande echelle dans le cadre duquel 8000 truites arc-en-ciel ont ete reprises sur une periode de 3 ans (2012-2014). Des variations temporelles et spatiales marquees de la croissance de la longueur et du poids concordant avec les predictions des modeles de von Bertalanffy et bioenergetiques, respectivement, ont ete notees. Le coefficient de croissance et la variation annuelle de la longueur asymptotique constituaient d'autres indices de variations saisonnieres. Les modeles bioenergetiques ont montre une plus grande variabilite de la croissance en poids d'une saison et d'une annee a l'autre qu'entre les differents troncons. Ces motifs concordent avec de fortes variations saisonnieres de la derive d'invertebres et des effets de la turbidite sur l'efficacite de l'approvisionnement. Les taux de croissance et l'embonpoint les plus grands ont ete observes dans les troncons inferieurs caracterises par des densites de truites plus faibles. Les resultats indiquent que la reduction de l'abondance des truites arc-en-ciel dans le Glen Canyon se traduira vraisemblablement par l'augmentation de la taille des truites dans la peche en aval et pourrait en reduire la dispersion dans le Grand Canyon.

Early detection increases the probability that suppression or eradication efforts will be successful because invasive populations are small and localized (Vander Zanden et al. 2010). However, most invasive species are not detected early because current tools have low detection probabilities when target species are rare and the sampling effort required to achieve acceptable detection capabilities with current tools is seldom tractable (Jerde et al. 2011). As a result, many invasive species go undetected until they are abundant and suppression efforts become costly.

We evaluated stability and movement of the estuarine intertidal zone along eastern Gulf of Mexico, known as the "Big Bend" of Florida. This relatively undeveloped, low-energy coast is dominated by broad expanses of tidal marsh, providing an opportunity to observe unobstructed response of a coastal ecosystem to SLR. Features from nineteenth century topographic surveys and late twentieth century satellite imagery were compared. Relative change was calculated for intertidal area and lateral migration over 120 years, a period when tidal amplitude increased in addition to SLR. Loss of tidal marsh at the shoreline was -43 km super(2), representing a 9 % loss to open water. At the same time, 82 km super(2) of forest converted to marsh and 66 km super(2) of forest converted to forest-to-marsh transitional habitat. The result was a net regional gain of 105 km super(2) of intertidal area, an increase of 23 %, constituting a marine transgression of coastal lowlands. Forest retreat was lower at zones of high freshwater input, attributable to salinity moderation and was further complicated by coastal morphology and land-use practices. Shoreline migration may not represent full extent of habitat change resulting from SLR in regions with low coastal gradients. Forest retreat was consistent with what would be predicted by an inundation model; however, shoreline loss was considerably less, resulting in a net increase in intertidal area in this sediment-limited coast.

Simultaneous application of cationic (Plus) and anionic (MIEX) ion exchange resin in a single contact vessel was tested at pilot and bench scales, under multiple regeneration cycles. Hardness removal correlated with theoretical predictions; where measured hardness was between 88 and 98% of the predicted value. Comparing bench scale DOC removal of solely treating water with MIEX compared to Plus and MIEX treated water showed an enhanced DOC removal, where removal was increased from 0.5 to 1.25 mg/L for the simultaneous resin application compared to solely applying MIEX resin. A full scale MIEX treatment plant (14.5 MGD) reduced raw water DOC from 13.7 mg/L to 4.90 mg/L in the treated effluent at a bed volume (BV) treatment rate of 800, where a parallel operation of a simultaneous MIEX and Plus resin pilot (10 gpm) measured effluent DOC concentrations of no greater than 3.4 mg/L, even at bed volumes of treatment 37.5% greater than the full scale plant. MIEX effluent compared to simultaneous Plus and MIEX effluent resulted in differences in fluorescence intensity that correlated to decreases in DOC concentration. The simultaneous treatment of Plus and MIEX resin produced water with predominantly microbial character, indicating the enhanced DOC removal was principally due to increased removal of terrestrially derived organic matter. The addition of Plus resin to a process train with MIEX resin allows for one treatment process to remove both DOC and hardness, where a single brine waste stream can be sent to sewer at a full-scale plant, completely removing lime chemical addition and sludge waste disposal for precipitative softening processes.

These peaks are indicative of a sediment source region in the southern part of the Proterozoic Belt Supergoup basin in central Idaho, which hosts 1800-1650 Ma detrital zircons and which was intruded by rift-related 1380 Ma bimodal plutons and sills. Belt rocks were strongly uplifted and eroded during Late Cretaceous Sevier shortening and fed four paleoriver systems. The Lemhi Pass-Hawley Creek river system flowed east and sourced the Beaverhead-Harebell-Pinyon nonmarine megafan in the Cordilleran foreland basin. The Kione River flowed southwest to northern California, where it sourced a very large, ca. 82-80 Ma, approximately 600-m-thick delta and submarine fan complex within the northern Great Valley forearc basin. Considerable Kione detritus also transited the forearc basin to reach the Franciscan trench, sourcing a pulse of deposition and subduction accretion in central California and even part of southern California. The Swakane River flowed northwest out of Idaho into Washington, sourcing the protolith for the high-grade Swakane gneiss. More speculatively, a Yakutat River may have flowed northwest and deposited Yakutat strata in a trench off Washington or British Columbia, before those rocks were translated north to southeastern Alaska. Recognition of a major source area in central Idaho for zircons with an uncommon age of 1380 Ma helps constrain the ca. 85-65 Ma paleogeography and paleotectonics of major sectors of the North American convergent margin orogen.

AN - 1754084173; 26330169 AB - The presence of mercury (Hg), particularly methylmercury (MeHg), is a concern for both human and ecological health as MeHg is a neurotoxin and can bioaccumulate to lethal levels in upper trophic level organisms. Recent research has demonstrated that coagulation with metal-based salts can effectively remove both inorganic mercury (IHg) and MeHg from solution through association with dissolved organic matter (DOM) and subsequent flocculation and precipitation. In this study, we sought to further examine interactions between Hg and DOM and the resulting organo-metallic precipitate (floc) to assess if (1) newly added IHg could be removed to the same extent as ambient IHg or whether the association between IHg and DOM requires time, and (2) once formed, if the floc has the capacity to remove additional Hg from solution. Agricultural drainage water samples containing ambient concentrations of both DOM and IHg were spiked with a traceable amount of isotopically enriched IHg and dosed with ferric sulfate after 0, 1, 5, and 30 days. Both ambient and newly added IHg were removed within hours, with 69-79 % removed. To a separate sample set, isotopically enriched IHg was added to solution after floc had formed. Under those conditions, 81-95 % of newly added Hg was removed even at Hg concentrations 1000-fold higher than ambient levels. Results of this study indicate coagulation with ferric sulfate effectively removes both ambient and newly added IHg entering a system and suggests rapid association between IHg and DOM. This work also provides new information regarding the ability of floc to remove additional Hg from solution even after it has formed.

This paper describes a regional habitat suitability modeling approach to evaluating how changes in management from Everglades restoration may affect the CSSS. The Cape Sable Seaside Sparrow Marl Prairie Indicator (CSSSMarlPrairie) is a spatially explicit model that integrates frequency (return periods) of target hydrologic conditions to simulate the anticipated response of marl prairie CSSS habitats to fluxing hydropatterns resulting from restoration projects, water management operations, and climatic change. The model integrates CSSS field survey data with the hydrologic targets at the resolution of the hydrologic simulation model (in this case, the Regional Simulation Model). The application of return periods for hydrologic events provides a novel approach for simulation of anticipated marl prairie responses in the southern Everglades and is readily applicable to evaluating targets of modeled wetland restoration scenarios elsewhere. CSSSMarlPrairie is intended to be used for decision support, in association with a suite of ecological models for additional species of management concern, to facilitate planning of ecosystem restoration projects such as those in the Comprehensive Everglades Restoration Plan and recovery of the marl prairie habitats of the CSSS. A tentatively selected restoration plan for the central Everglades is projected to have mostly minor overall impacts to marl prairie CSSS habitats. Local substantial habitat shifts in and adjacent to designated habitat boundaries have been identified, however, that warrant management consideration.

Growing perennial grasses such as switchgrass (Panicum virgatum L.) for biomass (e.g., cellulosic biofuel feedstocks) instead of annual row crops in these high relief waterway buffers can improve local environmental conditions (e.g., reduce soil erosion and improve water quality through lower use of fertilizers and pesticides) and ecosystem services (e.g., minimize drought and flood impacts on production; improve wildlife habitat, plant vigor, and nitrogen retention due to post-senescence harvest for cellulosic biofuels; and serve as carbon sinks). The main objectives of this study are to: (1) identify cropland areas with high topographic relief (high runoff potentials) and high switchgrass productivity potential in eastern Nebraska that may be suitable for growing switchgrass, and (2) estimate the total switchgrass production gain from the potential biofuel areas. Results indicate that about 140,000 hectares of waterway buffers in eastern Nebraska are suitable for switchgrass development and the total annual estimated switchgrass biomass production for these suitable areas is approximately 1.2 million metric tons. The resulting map delineates high topographic relief croplands and provides useful information to land managers and biofuel plant investors to make optimal land use decisions regarding biofuel crop development and ecosystem service optimization in eastern Nebraska.

Circa 946 AD, Paektu produced one of the largest volcanic eruptions in recorded history, the so-called Millennium Eruption (ME), whose combined fall and pyroclastic flow deposits total approximately 25 km3 dense rock equivalent (95% commendite, 5% late stage trachyte). Despite its recent and potentially destructive history, the volcano is not well studied due to its relative inaccessibility. A seismic swarm beneath the volcano's summit in 2002-2005 spurred a unique collaboration between scientists from the DPRK, US, and the UK with the goals of characterizing Paektu's eruptive history and assessing its current state of activity. We present new results from this collaboration, including major and trace element (XRF, EMP and SHRIMP-RG) and volatile data (SHRIMP-RG and FTIR) on feldspar-, clinopyroxene-, and olivine-hosted melt inclusions (MI), matrix glasses, and bulk pumices from four ME comendites and one ME trachyte. MI are halogen rich (F< or =4000 ppm, Cl< or =5000 ppm) with moderate S (< or =250 ppm) and H2O (< or =4 wt%) and minimal CO2 (< or =15 ppm, detection limit nearly equal 2 ppm). H2O contents in comendite MI indicate saturation pressures (at 725 degrees C) of nearly equal 150 MPa, corresponding to a magma chamber depth of nearly equal 6 km, similar to the depth inferred for the magmatic injection thought to have resulted in the 2002-05 earthquake swarm. ME comendite is consistent with a ca. 25% residual melt by fractional crystallization from an ME trachyte parent. Published U-series zircon ages from ME comendite indicate a magma residence time of 11ky. Thus, the late stage ME trachyte likely represents a mafic recharge event of a melt separate from but geochemically similar to the original ME comendite parent.

Two examples from the Aleutian arc highlight 1) segregation of silicic melt from an intermediate mush, and 2) "defrosting" of a shallowly emplaced intrusion. Augustine Volcano erupted a late Pleistocene rhyolite pumice fall that we link through zircon geochronology to cumulate dioritic blocks, ripped from Augustine's shallow magmatic plumbing system and ejected during the 2006 eruption. Unpolished zircon rims from the rhyolite yield a U-Th age of nearly equal 25 ka, and interiors yield a dominant age population of nearly equal 26 ka. Zircons from diorites have interior ages and compositions indistinguishable from those of the rhyolite. The diorites, rhyolite, and early Holocene dacites define whole-rock linear unmixing trends consistent with melt (rhyolite) extraction from a mush (dacites), leaving behind a cumulate residue (diorites). A volatile-rich basalt erupted just prior to the rhyolite likely facilitated melt extraction from the mush. The rhyolitic Hayes River ignimbrite, erupted from Hayes volcano, contains dense porphyry blocks that match pumices in composition and phenocryst content and are samples of a shallow intrusion. Autocrystic monazite accommodated up to several weight % Th and significantly affected the U-Th ratio of the magma during differentiation. An isochron for early melt and low-U monazites yields an age of nearly equal 67 ka, whereas one for late melt and high-U monazites yields nearly equal 42 ka. This younger age is indistinguishable from the laser single crystal Ar-Ar age for sanidine of 41+ or -2 ka (1 sigma). We interpret the apparent nearly equal 25 k.y. crystallization interval to represent the assembly and differentiation timescale associated with the Hayes magma body. Sharp reverse zoning in sanidine from pumice (but not porphyry) records a thermal pulse not seen in the more slowly reacting phases, suggesting that a rejuvenation event occurred just prior to eruption.

Because the subducting plate beneath the Cascade arc is relatively young and hot, slab melt generation is considered possible. To better understand the role of slab melt in north Cascades magmas, this study focused on petrogenesis of high-Mg andesites (HMA) and basaltic andesites (HMBA) from Mt. Baker and Glacier Peak, Washington. HMA have unusually high Mg# relative to their SiO2 contents, as well as elevated La/Yb and Dy/Yb ratios that are interpreted to result from separation of melt from a garnet-bearing residuum. Debate centers on the garnet's origin as it could be present in mineral assemblages from the subducting slab, deep mantle, thick lower crust, or basalt fractionated at high pressure. Whole rock analyses were combined with major, minor, and trace element analyses to understand the origin of these HMA. In the Tarn Plateau (Mt. Baker) flow unit (51.8-54.0 wt.% SiO2, Mg# 68-70) Mg#s correlate positively with high La/Yb in clinopyroxene equilibrium liquids, suggesting an origin similar to that of Aleutian adakites, where slab-derived melts interact with the overlying mantle to become Mg-rich and subsequently mix with mantle-derived basalts. The source for high La/Yb in the Glacier Creek (Mt. Baker) flow unit (58.3-58.7 wt.% SiO2, Mg# 63-64) is more ambiguous. High whole rock Sr/P imply origin from a mantle that was hydrated by an enriched slab component (fluid + or - melt). In the Lightning Creek (Glacier Peak) flow unit (54.8-57.9 SiO2, Mg# 69-72) Cr and Mg contents in Cr-spinel and olivine pairs suggest a depleted mantle source, and high whole rock Sr/P indicate hydration-induced mantle melting. Hence Lightning Creek is interpreted have originated from a refractory mantle source that interacted with a hydrous slab component (fluid + or - melt). Our results indicate that in addition to slab-derived fluids, slab-derived melts also have an important role in the production of HMA in the north Cascade arc.

Klemetti and Clynne (2014) showed that felsic eruptions at Lassen reflect remobilization of resident rhyodacitic crystal mush by intrusion of mafic magma. To better understand the rejuvenation and eruption triggering process, we calculate crystallization temperatures and pressures from clinopyroxene-liquid equilibria on mafic enclaves that provide our closest approach to the composition of mafic magmas delivered to the shallow system. Our goal is to examine whether and to what extent cooling and crystallization occur after recharge, which bears on whether recharge, mixing, or partial crystallization (and consequent vapor saturation) provide the trigger for eruption. We use results from the cpx-liq barometer (1.7 kbar) as input to calculate T for other phases (plagioclase, olivine and amphibole) found in mafic enclave samples. Cpx crystallizes at 1100-1150 oC and olivine precipitates at similar to slightly higher temperatures. Cpx and ol are followed by plagioclase (1000-1050 oC), amphibole (875-1000 oC), and Fe-Ti oxides (1030-1050 oC). These temperatures indicate that recharge magmas are incompletely crystallized as they enter the shallow reservoir of cooler ( nearly equal 725-750 oC, Quinn et al., 2013) felsic crystal mush, and that significant cooling of the mafic magma occurs during mixing and prior to eruption. Such cooling intervals indicate that recharge is not the proximal cause of eruption, but rather that vapor saturation, following a period of mixing and cooling, leads to increased magma overpressure that causes eruption. Interestingly, the Lassen Peak 27 ka volcanics (at 2.09 km3), have a greater volume than either of Chaos Crags (1.2 km3) and the 1915 (0.03 km3) eruption, but our results indicate that their thermal histories are similar. This suggests that while volumes of mafic recharge may control the degree of interaction with felsic crystal mush (e.g., Clynne, 1999), and eventually the volume of erupted magma, recharge volumes do not affect eruption triggering mechanisms.

Crystals residing in these reservoirs have been shown to represent valuable archives of the chemical and physical evolution of reservoirs, and the time scales of this evolution. This presentation addresses the question of "What do crystals "see" and record about processes within the upper crust? And how is that view similar or different between plutonic and volcanic records?" Three general observations emerge from study of the ages of crystals, combined with crystal-scale geochemical data: 1) Patterns of isotopic and trace-element data over time in zircon crystals from a given magmatic system (e.g., Yellowstone, WY, and Taupo Volcanic Zone, New Zealand) can show systematic changes in the degree of heterogeneity, consistent with extraction of melts from a long-lived (up to 100s of kyr), heterogeneous crystal mush and in some cases continued crystallization and homogenization of the magma during a short period (< a few kyr) preceding eruption. 2) Thermal histories of magma storage derived from crystal records also show that the vast majority of time recorded by major phases was spent in storage as a crystal mush, perhaps at near-solidus conditions. 3) Comparison of ages of accessory phases in both plutonic blocks and host magmas that brought them to the surface do not show a consistent relationship between the two. In some cases, zircons from plutonic blocks have age spectra much older than zircon in the host magma. In other cases, host and plutonic block zircons have similar age spectra and chemical characteristics, suggesting a closer genetic connection between the two. These observations suggest that crystals in plutonic bodies, if examined at similar spatial and temporal scales to those in volcanic rocks, would show records that are highly heterogeneous in chemistry and age on the scale of a pluton or a lobe of a pluton, but that local regions of limited chemical and age variability may be preserved as remnants of the melt extraction and amalgamation process.

For Raman spectroscopy the LIBS Nd:YAG laser is frequency-doubled to 532 nm (green Raman). A transmission spectrometer with an intensified CCD covers 150-4400 cm-1 spectral range at a resolution of 10 cm-1. The system is adjustably time-gated, removing much of the mineral fluorescence from the Raman spectra and also facilitating time-resolved fluorescence studies. The infrared range covers 1.3-2.6 microns in addition to the existing 400-840 nm range on ChemCam. Additional upgrades include doubling the LIBS resolution in the 535-860 nm range and adding color to the Remote Micro-Imager (RMI), which is the highest resolution remote imager on the rover. A large-scale effort is being applied to the on-board standards, being led by U. Valladolid in Spain, with targets contributed by many institutions. The number of geological targets will be increased from 8 (on ChemCam) to 22, planned to include end-member plagioclase feldspars, hi- and low-Ca pyroxene, olivines, several fine-grained basalts, hematite, jarosite, carbonates, apatite, and several synthetic targets doped with trace elements. Three Spectralon targets are planned for IR calibration and several color bands for the RMI. All but the Spectralon and color bands should be available for LIBS calibration, and many are also being designed for Raman and VISIR calibration. For LIBS this collection of standards will significantly improve the accuracy relative to ChemCam; other precision improvements are anticipated to come from correcting for variable plasma temperature. The presentation will illustrate how Mars datasets will be significantly improved via this multi-technique approach and will give a first look at prototype SuperCam spectra.

To supplement these we collected 3800 detailed media and first-person accounts of macroseismic effects that included sufficiently detailed information to assign intensities. Our resultant macroseismic intensity map reveals the distribution of shaking in Nepal and the adjacent Gangetic basin. A key observation was that only in rare instances did near-field shaking intensities exceed intensity 8 on the European Macroseismic Scale (EMS), a level that corresponds with heavy damage or total collapse of many unengineered masonry structures. Within the Kathmandu Valley, intensities were generally 6-7 EMS, with generally lower intensities in the center of the valley than along the edges and foothills. This surprising (and fortunate) result can be explained by the nature of the mainshock ground motions, which were dominated by energy at periods significantly longer than the resonant periods of vernacular structures throughout Kathmandu. Outside the Kathmandu Valley the earthquake took a heavy toll on a number of remote villages, where many especially vulnerable masonry houses collapsed catastrophically in shaking equivalent to 7-8 EMS. Intensities were also generally higher along ridges and small hills, suggesting that topographic amplification played a significant role in controlling damage. The spatially rich intensity data set provides an opportunity to consider several key issues, including amplification of shaking in the Ganges basin, and the distribution of shaking across the rupture zone. Of note, relatively higher intensities within the near-field region are found to correlate with zones of enhanced high-frequency source radiation imaged by teleseismic back-projection (Avouac et al., 2015). We further reconsider intensities from a sequence of earthquakes on 26 August 1833, and conclude the largest of these ruptured at least part of the same plate boundary segment as did the Gorkha earthquake.

Previous workers conclude that wave attenuation rates decrease exponentially with distance from the marsh edge and are dependent on site and species-specific plant characteristics (Yang et al., 2011). Sediment deposition may exhibit similar patterns; however, sediment, geomorphic and habitat models seldom integrate site-specific biophysical plant parameters into change analyses. We paired vegetation and sediment dynamic studies to: (1) characterize vegetation structure, (2) estimate sediment available for deposition, (3) estimate rate, distribution and composition of sediment deposits, (4) determine sediment accumulation on vegetation, (5) compare sediment deposition within dense tidal wetland relative to non-vegetated tidal flat. These studies integrate a variety of monitoring methods, including the use of sediment traps, turbidity sensors, side-on photographs of vegetation and remote sensing image analysis. We compared sedimentation data with vegetation characteristics and spatial distribution data to examine the relative role of vegetation morphologic traits (species, stem density, biomass, distribution, tidal channels, etc.) on sediment dynamics. Our study is focused on Port Susan Bay of Washington State; a protected delta that has experienced up to 1 kilometer of marsh retreat (loss) over the past fifty years. Preliminary results show that the highest winter deposition occurred in the high marsh/mid-marsh boundary, up to 300m inland of the marsh edge, where bulrush species are most dense. These results will inform restoration efforts aimed at reestablishing sediment supply to the retreating marshland. This research is necessary to understand the vulnerability and adaptability of coastal marshlands to climate change related stressors such as, increased water levels (sea-level rise) and wave energy.

The occurrence of these features provides new and important constraints on the origins of these sedimentary deposits and of their broader geologic histories. Regional surveys and mapping of these features is warranted given the plethora of recently acquired observations by the Mars Reconnaissance Orbiter. Select sedimentary and deformational features were identified using High Resolution Imaging Science Experiment (HiRISE) observations and stereo pairs, along with Context camera images. Feature locations were cataloged using Java Mission-planning and Analysis for Remote Sensing (JMARS) the geospatial information system. Images acquired in and around Hebes, Ophir, Tithonium, Candor, Ius, Melas and Coprates Chasmata were the focus of this investigation. Mass wasting processes, soft-sediment deformation structures, and fan-like deposits are known to occur in abundance across the Valles Marineris region. For this reason, the features recorded in this investigation were landslides, contorted bedding, injectites, putative mud volcanoes, faults, folds, and fan-shaped deposits. Landslides, faults, and fan-shaped deposits were found to be common occurrences, while contorted bedding, injectites, putative mud volcanoes, and folds occur less frequently and in clusters.

Several research groups have developed quantitative satellite-based volcanic ash products and some of these are in operational use by Volcanic Ash Advisory Centers around the world to aid in characterizing cloud properties and forecasting regions of ash hazard. The algorithms applied to the satellite data utilize a variety of techniques, and thus produce results that differ. The World Meteorological Organization has recently sponsored an intercomparison study of satellite-based retrievals with four goals: 1) to establish a validation protocol for satellite-based volcanic ash products, 2) to quantify and understand differences in products, 3) to develop best practices, and 4) to standardize volcanic cloud geophysical parameters. Six volcanic eruption cases were considered in the intercomparison: Eyjafallajoekull, Grimsvoetn, Kelut, Kirishimayama, Puyehue-Cordon Caulle, and Sarychev Peak. Twenty-four algorithms were utilized, which retrieved parameters including: ash cloud top height, ash column mass loading, ash effective radius, and ash optical depth at visible and thermal-infrared wavelengths. Results were compared to space-based, airborne, and ground-based lidars; complementary satellite retrievals; and manual "expert evaluation" of ash extent. The intercomparison results will feed into the International Civil Aviation Organization "Roadmap for International Airways Volcano Watch", which integrates volcanic meteorological information into decision support systems for aircraft operations.

Critical impact information is often stored in ephemeral news articles or other isolated resources, which cannot be queried or located easily. A global ash impacts database would improve 1) warning messages, 2) public and lifeline emergency preparation, and 3) eruption response and recovery. Ashfall can have varying consequences, such as disabling critical lifeline infrastructure (e.g. electrical generation and transmission, water supplies, telecommunications, aircraft and airports) or merely creating limited and expensive inconvenience to local communities. Impacts to the aviation sector can be a far-reaching global issue. The international volcanic ash impacts community formed a committee to develop a database to catalog the impacts of volcanic ash. We identify three user populations for this database: 1) research teams, who would use the database to assist in systematic collection, recording, and storage of ash impact data, and to prioritize impact assessment trips and lab experiments 2) volcanic risk assessment scientists who rely on impact data for assessments (especially vulnerability/fragility assessments); a complete dataset would have utility for global, regional, national and local scale risk assessments, and 3) citizen science volcanic hazard reporting. Publication of an international ash impacts database will encourage standardization and development of best practices for collecting and reporting impact information. Data entered will be highly categorized, searchable, and open source. Systematic cataloging of impact data will allow users to query the data and extract valuable information to aid in the development of improved emergency preparedness, response and recovery measures.

While a broad coincidence between the DT eruptions and the KPB is increasingly clear, variables such as tempo, volume of eruptions, and amount of associated climate-modifying volatiles, are too poorly constrained to properly assess causality. In order to appropriately test whether the DT played a role in the mass extinctions a high-precision geochronologic framework defining the timing and tempo of volcanic eruptions is needed. Recent high-precision U/Pb dating of zircons from inferred paleosols (red boles) and melt segregation horizons is the only available geochronology of the DT that is sufficiently precise to resolve age differences of less than 100 ka (Schoene et al., 2015). While this technique can achieve high-precision dates for individual zircon crystals, protracted age distributions may not include the actual eruption age. Moreover, the applicability of U/Pb dating in the DT is limited as suitable material is only sporadically present and therefore the technique is unlikely to achieve the resolution necessary to assess the tempo of DT eruptions. To mediate these limitations, we present new high-precision 40Ar/39Ar ages for plagioclase separated from the lava flows sampled from each of ten chemostratigraphically-defined formations within the Western Ghats. Multiple (N = 1-4) plateau ages from each sample and detailed neutron fluence monitoring during irradiation yield ages with precision commonly better than 100 ka (1 sigma). Results provide the first precise location of the KPB within the DT eruption sequence, which approximately coincides with major changes in eruption frequency, flow-field volumes, extent of crustal contamination, and degree of fractionation. Collectively, these results suggest that a state shift occurred in the DT magma system within nearly equal 50 ka of the Chicxulub impact, consistent with transient effects of seismic energy associated with the impact. Further, our new data invalidate the concept of three discrete eruption pulses in the Western Ghats (Chenet et al., 2007, 2009; Keller et al., 2008) and rather indicate only a sharp increase in mean volumetric eruption rates near the KPB.

Computational models are typically used to predict ash concentrations, using inputs such as plume height, eruptive duration, and wind speeds. The models also depend on empirical parameters, such as the entrainment of atmospheric air as a ratio of the air inflow speed and the jet speed. Entrainment of atmospheric air plays a critical role in the behavior of volcanic plumes in the atmosphere, impacting the mass flow rate, buoyancy, and particle concentration of the plume. This process is more complex in a crosswind, leading to greater uncertainty in the model results. To address these issues, a laboratory-scale study has been conducted to improve the entrainment models. Observations of a vertical, unconfined jet are performed using Particle Image Velocimetry, while varying jet density using different compressed gases and Reynolds number. To test the effects of a crosswind on plume entrainment rates, these are then compared with similar jet experiments in a wind tunnel. A series of jet geometries, jet speeds and tunnel speeds are considered. The measured velocities are used to determine the entrainment response, which can be used to determine ash concentration over time as atmospheric air is entrained into the plume. We also quantify the mean and the fluctuations in flow velocity.

Integrating textural, petrological, geochemical, and geochronological information on such deposits with geophysical signals (gravimetry, seismology, MT surveys) suggest incremental growth and evolution of subvolcanic magmas bodies that are dominated by high crystallinity mush zones, but remain in parts, and during periods of relatively high magma fluxes, sufficiently liquid to erupt. The eruptible upper portions are either extracted melt from the mush, or rejuvenated fractions of it, and constitute only a small volumetric fraction of the vertically extensive mushy batholithic magma body. The high-flux, ignimbrite flare-up phases are typically preceded by waxing magmatism that prime the crust to hold large upper crustal silicic reservoirs where the most evolved magmas, rhyolites, are likely to be generated. Ages and compositional complementarities between the silicic volcanic and plutonic lithologies suggest that they are intimately linked, although plutonic masses will be inherently more complex and longer-lived than any volcanic systems spawned from them. Gas exsolution within such mushy reservoirs, and accumulation of the low density bubbles in the most melt-rich parts of the system, will also enhance eruptibility, emphasizing some of the observed chemical differences between evolved plutonic and volcanic rocks (e.g., typically higher Rb/Sr ratios in volcanic units).

The two primary phases of eruption, separated by a few hours, produced pyroclastic density currents, lahars, and spectacular vertical eruption columns that rose into the stratosphere. Clear weather conditions allowed the populated areas of Puerto Montt and Puerto Varas full view of the lightning-rich eruption, which was rapidly shared through social media. A wealth of remote-sensing data was also publically available in near real-time. We used this information to assess the eruption behavior by combining satellite-based umbrella growth rates, and the location and frequency of volcanic lightning. Umbrella expansion rates from GOES-13 satellite retrievals correspond to eruption rates of about 4x106 kg s-1 for the first eruptive phase and 6x106 kg s-1 for the second phase, following the approach of Pouget et al. (2013, JVGR, 258, 100-112). The location and timing of lightning flashes were obtained from the World Wide Lightning Location Network (WWLLN) Global Volcanic Lightning Monitor, which is updated approximately every minute (Ewert et al., 2010, Fall AGU Abstract AE31A-04). Interestingly, the onset of detected flashes was delayed by nearly equal 30 min after the start of each eruptive phase. Lighting provided a useful proxy for the waxing or waning intensity of the eruption, and helped identify the end of significant ash emissions. Using the 1-D volcanic plume model Plumeria, we have also simulated the vertical distribution of ash and ice in the plumes to examine potential causes of the extraordinary amount of volcanic lightning (1,094 flashes detected). Our analysis provides information on eruption timing, duration, and mass flow rate, which are necessary for ash dispersal modeling within hours of eruption. Results are also consistent with the field-based measurements of total erupted volume. We suggest that the combination of satellite-detected umbrella expansion rates with lightning data may provide a useful approach to constrain near real-time inputs for ash dispersal models and hazard warnings.

Aluminoborosilicate glasses with excess modifier (Ca, La and Y- aluminoborosilicate) quenched from melts at 1-3 GPa were studied with B-11 and Al-27 MAS NMR to assess relative effects on two different network cations. Structural changes in the Y-aluminoborosilicate are dramatic, going from mostly AlO4 at low pressure to mostly AlO5 and AlO6 at 3 GPa. Large increases in BO4 (vs. BO3) are also seen. Mg-aluminosilicate glasses, both tectosilicate (Mg2Al4Si6O20) and with excess modifier composition (Mg3Al2Si6O18) quenched from melts at 1-3 GPa pressure were studied with Al-27 MAS NMR. In contrast to our previous study (Bista et al., Am. Min., in press) of jadeite glass, where only 0.5% of fivefold aluminum was seen in glass recovered from 3 GPa, five and six fold aluminum species increase significantly with increasing pressure in both Mg aluminosilicate glass compositions studied here. We observe that the tectosilicate Mg aluminosilicate glass has more higher coordinated aluminum than the excess modifier containing composition in the pressure range in our study. In the previous study (Bista et al., in press) of jadeite and calcium aluminosilicate (Ca3Al2Si6O18) glasses, 6-8% densification was observed in glasses recovered from 3 GPa. In this study of Mg aluminosilicate glasses, we observe 12% densification in glasses recovered from 3 GPa. Both types of observation confirm that structural and density changes with pressure are enhanced by higher field strength modifier cations, and will be especially important in Mg- and Fe-rich mantle melts.

This process is often modulated by long-lived (10-100 k.y.) shallow (350 ka). These data support a model of long-lived zircon-saturated silicic mushes existing under the LVC during the Rockland caldera complex stage and since the end of the Brokeoff Volcano stage (590-385 ka eruption ages). Preliminary zircon data from the Old Maid stage ( nearly equal 0.2 ka eruption age) at MH indicate two broad age groups. Younger zircon (100 ka) are generally consistent with U-Th ages from plagioclase ( nearly equal 120 ka U-Th), indicating a long-lived zircon-saturated crystal mush tapped by Timberline and Old Maid lavas. At both of these volcanoes, silicic crystal mushes interact with intruding mafic magma, producing monotonous mixed andesite-dacite compositions at MH and dacitic-rhyodacitic mixed and mingled magmas at the LVC. This difference in lava compositions may be controlled by the volume and duration of basaltic intrusions, the duration of the mafic magma's interaction with the crystal mush along with the geometry, volume and conditions (P-T-x) within the crystal mush.

The eruption produced 17 km3 of ashfall and 11 km3 of pyroclastic flow deposits that filled nearby valleys, creating what is today known as the Valley of Ten Thousand Smokes. These voluminous pyroclastic deposits continue to pose hazards when strong winds in the valley resuspend ash in times of low snow cover. These resuspension events may be confined to the valley and only recorded when there are local observations (web camera images, field crew). Occasionally, however, these events can loft ash up to altitudes of several kilometers and extend up to 250 km downwind, where it becomes an aviation hazard. A compilation of satellite observations and pilot reports indicate that such significant events occurred on at least 19 occasions since 2003. The longest duration events occurred in the autumn months of September and October. Predicting the resuspension of ash requires estimates of when the ash is exposed (low snow cover), the magnitude of surface wind gusts, and the threshold friction velocity (u*). Models of u* require a characterization of the source ash (density, grain-size distribution) as well as soil moisture. We have sampled source deposits and have installed instruments in the Katmai region to record the relevant meteorological parameters in order to better predict these resuspension events. Using real-time measurements coupled with high-resolution (6 km, 1 hour) meteorological forecast products and a reanalysis of conditions that produced historic events, we constrain the parameters applicable the resuspension of Novarupta ash thus improving our ability to forecast this potential ash hazard. The volcanic ash dispersion and deposition model, Ash3d, will be used to forecast the transport of the resuspended ash.

Typically, a myriad of electrical impulses originating from directly above the vent are observed first and the ensemble has durations of several seconds. The impulses are distinct from those produced by typical types of thunderstorm lightning, and have earned the moniker "continuous RF" due to their high rate and long-lasting nature . Several seconds after the onset of these impulses, small (100s of meters to several kilometers) lightning discharges occur in the plume and near the vent, and have electrical signatures similar to typical thunderstorm lightning. In eruptions with plume heights reaching 8-10 km or more, large scale (10s of kilometers) lightning discharges are observed throughout the plume several minutes after the onset of an explosive event.In May 2015, a campaign began to study the various types of small-scale electrical activity, including continuous RF, during explosive eruptions of Sakurajima volcano in Kyushu, Japan. The volcano was instrumented with two seismometers, two infrasound arrays, a high sensitivity video camera, an infrared camera, two high speed video cameras, still cameras, a 10-station Lightning Mapping Array, slow and fast electric field change sensors, and a broadband very high frequency (VHF) antenna. With these instruments, a robust data set of both the volcanic activity and electrical activity was collected. The preliminary data have revealed brief (1-2 seconds) bursts of continuous RF simultaneous with the onset of the more energetic explosions. Occurrence of continuous RF may be linked to mass eruption rate, explosivity, or grain size. Due to its unique nature, detection of continuous RF is an unambiguous indicator of explosive volcanic activity and is therefore useful for real-time volcano monitoring.

Because melt and aqueous fluids are a few orders of magnitude more electrically conductive than unmelted peridotite, the conductivity-mapping magnetotelluric (MT) method is well-suited to imaging fluids and melt beneath arc volcanoes. Here we present conductivity results from an amphibious MT profile crossing Okmok volcano in the central Aleutian arc. The Aleutian arc is one of the most volcanically active regions in North America, making it an ideal location for studying arc magnetism. Okmok volcano, located on the northeastern portion of Umnak Island, is among the most active volcanoes in the Aleutian chain. In addition to two caldera-forming events in the Holocene, numerous eruptions in the past century indicate a robust magmatic supply. Previous coarse resolution seismic studies have inferred a crustal magma reservoir. In order to investigate the role fluids play in melting the mantle wedge, how melts ascend through the corner flow regime of the mantle wedge, how melt migrates and is stored within the upper mantle and crust, and how this impacts explosive caldera forming eruptions, we carried out an amphibious geophysical survey across the arc in June-July 2015. Twenty-nine onshore MT stations and 10 offshore stations were collected in a 3D array covering Okmok, and 43 additional offshore MT stations completed a 300 km amphibious profile starting at the trench, crossing the forearc, arc and backarc. Thirteen onshore passive seismic stations were also installed and will remain in place for one year to supplement the twelve permanent stations on the island. Data collected by this project will be used to map seismic velocity and electrical conductivity variations within the arc, providing unique constraints on temperature, mineralogy and fluid content. This abstract covers preliminary MT constraints on the mantle and deep crust as inferred from the 300 km long amphibious profile. A companion abstract (Bennington et al.) considers the crustal magma chamber imaged by the 3D array.

OFDA leads and coordinates disaster responses overseas for the U.S. government and is a unique stakeholder concerned with volcano disaster risk reduction as an international humanitarian assistance donor. One year after the tragic eruption of Nevado del Ruiz in 1985, OFDA began funding USGS to implement VDAP. VDAP's mission is to reduce the loss of life and property and limit the economic impact from foreign volcano crises, thereby preventing such crises from becoming disasters. VDAP fulfills this mission and complements OFDA's humanitarian assistance by providing crisis response, capacity-building, technical training, and hazard assessments to developing countries before, during, and after eruptions. During the past 30 years, VDAP has responded to more than 27 major volcanic crises, built capacity in 12+ countries, and helped counterparts save tens of thousands of lives and hundreds of millions of dollars in property. VDAP responses have evolved as host-country capabilities have grown, but the pace of work has not diminished; as a result of VDAP's work at 27 volcanoes in fiscal year 2014, more than 1.3 million people who could have been impacted by volcanic activity benefitted from VDAP assistance, 11 geological policies were modified, 188 scientists were trained, and several successful eruption forecasts were made. VDAP is developing new initiatives to help counterparts monitor volcanoes and communicate volcanic risk. These include developing the Eruption Forecasting Information System (EFIS) to learn from compiled crisis data from 30 years of VDAP responses, creating event trees to forecast eruptions at restless volcanoes, and exploring the use of unmanned aerial systems for monitoring. The use of these new methods, along with traditional VDAP assistance, has improved VDAP's ability to assist counterparts with preparing for eruptions.

Here, we implement standard and innovative forecast models to predict the spatio-temporal distribution of triggered events. Key challenges addressed are: 1) the limited information on early aftershocks, 2) the low-productivity aftershock sequence in the near-source area, 3) the off-fault (>250 km) triggered events exemplified by the M=5.4 Xegar event, 3 hrs after the mainshock. We apply short-term empirical/statistical ETAS and physical forecast models, the latter based on the combination of rate/state friction law and Coulomb stresses. Within the physics-based model implementation we seek to evaluate the uncertainty related with the rupture style of triggered events by considering: 1) the geometry of active structures, 2) optimally oriented for failure faults and 3) all-potential faults described by the total stress field. The latter is represented by the full stress tensor before and after the mainshock and our analysis suggests that the preseismic stress magnitudes are still sufficient to cause earthquakes even after modification by the mainshock. The above remark reveals that there are no "stress shadows" affecting the spatial distribution of near-field aftershocks. It is also noted that the method allows for an a-priori determination of the rupture plan of the M=7.3 event, within the limit of uncertainty (20 degrees ). The results show that: (1) ETAS models underestimate the number of observed events, since they heavily base their good performance in small magnitude earthquakes, not available in the first few weeks after the mainshock, (2) far field triggered events are captured only by physics-based forecasts, and (3) the total stress method improves the predictability of larger magnitude events. We conclude that frontier regions benefit from the implementation of physics-based models since they have comparable to improved performance when compared with empirical/statistical models with the advantage of less demanding input parameters at real-time experiments.

Eruptions in the 20th century at Lassen Peak and Mount St. Helen demonstrated the active nature of Cascade volcanoes; the 1980 eruption of Mount St. Helens was a defining moment in modern volcanology. The first modern volcano hazards assessments were produced by the USGS for some Cascade volcanoes in the 1960s. A rich scientific literature exists, much of which addresses hazards at these active volcanoes. That said community awareness, planning, and preparation for eruptions generally do not occur as a result of a hazard analyses published in scientific papers, but by direct communication with scientists. Relative to other natural hazards, volcanic eruptions (or large earthquakes, or tsunami) are outside common experience, and the public and many public officials are often surprised to learn of the impacts volcanic eruptions could have on their communities. In the 1980s, the USGS recognized that effective hazard communication and preparedness is a multi-faceted, long-term undertaking and began working with federal, state, and local stakeholders to build awareness and foster community action about volcano hazards. Activities included forming volcano-specific workgroups to develop coordination plans for volcano emergencies; a concerted public outreach campaign; curriculum development and teacher training; technical training for emergency managers and first responders; and development of hazard information that is accessible to non-specialists. Outcomes include broader ownership of volcano hazards as evidenced by bi-national exchanges of emergency managers, community planners, and first responders; development by stakeholders of websites focused on volcano hazards mitigation; and execution of table-top and functional exercises, including evacuation drills by local communities.

The main purpose of these instruments is to allow fast in situ analyses of rocks and soils so that astronauts can quickly document sample characteristics and context, and make strategic decisions on sample selection in the context of predefined scientific objectives. As part of the Remote, In Situ, and Synchrotron Studies for Science and Exploration (RIS4E) investigation, we test the performance of candidate instruments and operational procedures through fieldwork expeditions that simulate lunar and asteroid environments on Earth. Our field site, Kilauea Volcano in Hawaii, is a lava field with landscape and mineralogy that represent a reasonable analog to the Moon and some differentiated asteroids. In this paper, we focus on one of the candidate instruments, the infrared multispectral imager. During field expeditions in 2014 and 2015, we explored the applicability of the multispectral imager in manned surface operations. From these expeditions, our instrument calibration techniques and data collection procedures matured. Current work focuses on assessment of data product usefulness, through comparison with detailed laboratory chemical and spectral measurements, and field descriptions of surface textures. Our field expeditions will continue in other analog locations to obtain improved understanding of the multispectral imager and its role in sampling workflow so that science return can be maximized in future human missions.

Despite vastly different material properties and environmental conditions, Titan's methane-based hydrologic system drives climatic and geologic processes that result in morphologic features with striking similarity to terrestrial counterparts, including vast equatorial dune fields, well-organized channel networks that route material through erosional and depositional landscapes defining source-to-sink sediment transport systems, and, perhaps most astonishingly, lakes and seas filled with liquid hydrocarbons. Using its various operating modes, the Cassini RADAR has provided a wealth of information regarding Titan's active surface-atmosphere system. In Synthetic Aperture Radar (SAR) mode, the RADAR has unveiled Titan's surface by producing backscatter maps with pixel scales of nearly equal 300 m. In altimetry mode, the RADAR has shown the elevation profile of surface features, including the liquid elevation of Titan's lakes and seas, revealed the roughness characteristics of the surface, and constrained the global shape. Most recently, the altimetry mode has doubled as a radar sounder that has successfully probed the depth and absorptivity of the lakes and seas. Data from the scatterometry and radiometry modes have been used to constrain material properties, including dielectric constants and volume scattering fractions, surface texture, and derive seasonal and diurnal temperature variations. Collectively, these datasets have revealed Titan's strange yet familiar nature, and demonstrated that it is one of the most compelling targets in our solar system. During our presentation, we will summarize these capabilities and review some of the most specular discoveries made by the Cassini RADAR.

EIS combines narrow-angle and wide-angle cameras (NAC and WAC) designed to address high-priority Europa science and reconnaissance goals. It will: (A) Characterize the ice shell by constraining its thickness and correlating surface features with subsurface structures detected by ice penetrating radar; (B) Constrain formation processes of surface features and the potential for current activity by characterizing endogenic structures, surface units, global cross-cutting relationships, and relationships to Europa's subsurface structure, and by searching for evidence of recent activity, including potential plumes; and (C) Characterize scientifically compelling landing sites and hazards by determining the nature of the surface at scales relevant to a potential lander. The NAC provides very high-resolution, stereo reconnaissance, generating 2-km-wide swaths at 0.5-m pixel scale from 50-km altitude, and uses a gimbal to enable independent targeting. NAC observations also include: near-global (>95%) mapping of Europa at < or =50-m pixel scale (to date, only nearly equal 14% of Europa has been imaged at < or =500 m/pixel, with best pixel scale 6 m); regional and high-resolution stereo imaging at <1-m/pixel; and high-phase-angle observations for plume searches. The WAC is designed to acquire pushbroom stereo swaths along flyby ground-tracks, generating digital topographic models with 32-m spatial scale and 4-m vertical precision from 50-km altitude. These data support characterization of cross-track clutter for radar sounding. The WAC also performs pushbroom color imaging with 6 broadband filters (350-1050 nm) to map surface units and correlations with geologic features and topography. EIS will provide comprehensive data sets essential to fulfilling the goal of exploring Europa to investigate its habitability and perform collaborative science with other investigations, including cartographic and geologic maps, regional and high-resolution digital topography, GIS products, color and photometric data products, a geodetic control network tied to radar altimetry, and a database of plume-search observations.

AN - 1861083553; 769873-110 AB - The internationally collaborative volcanic ash website (http://volcanoes.usgs.gov/ash/) has been an important global information resource for ashfall preparedness and impact guidance since 2004. Recent volcanic ashfalls with significant local, regional, and global impacts highlighted the need to improve the website to make it more accessible and pertinent to users worldwide. Recently, the Volcanic Ash Impacts Working Group (Cities and Volcanoes Commission of IAVCEI) redesigned and modernized the website. Improvements include 1) a database-driven back end, 2) reorganized menu navigation, 3) language translation, 4) increased downloadable content, 5) addition of ash-impact case studies, 7) expanded and updated references , 8) an image database, and 9) inclusion of cooperating organization's logos. The database-driven platform makes the website more dynamic and efficient to operate and update. New menus provide information about specific impact topics (buildings, transportation, power, health, agriculture, water and waste water, equipment and communications, clean up) and updated content has been added throughout all topics. A new "for scientists" menu includes information on ash collection and analysis. Website translation using Google translate will significantly increase user base. Printable resources (e.g. checklists, pamphlets, posters) provide information to people without Internet access. Ash impact studies are used to improve mitigation measures during future eruptions, and links to case studies will assist communities' preparation and response plans. The Case Studies menu is intended to be a living topic area, growing as new case studies are published. A database of all images from the website allows users to access larger resolution images and additional descriptive details. Logos clarify linkages among key contributors and assure users that the site is authoritative and science-based.

Geologic mapping and geochronology show that most Cascade volcanoes grew episodically on multiple scales with periods of elevated behavior lasting hundreds of years to ca. 100 kyr. Notable examples include the paleomag-constrained, few-hundred-year-long building of the entire 15-20 km3 Shastina edifice at Mt. Shasta, the 100 kyr-long episode that produced half of Mt. Rainier's output, and the 30 kyr-long episode responsible for all of South and Middle Sister. Despite significant differences in timing and rates of construction, total durations of active and ancestral volcanoes at discrete central-vent locations are similar. Glacier Peak, Mt. Rainier, Mt. Adams, Mt. Hood, and Mt. Mazama all have inception ages of 400-600 ka. Mt. St. Helens, Mt. Jefferson, Newberry Volcano, Mt. Shasta and Lassen Domefield have more recent inception ages of 200-300 ka. Only the Sisters cluster and Mt. Baker have established eruptive histories spanning less than 50 kyr. Ancestral volcanoes centered 5-20 km from active stratocones appear to have similar total durations (200-600 kyr), but are less well exposed and dated. The underlying mechanisms governing volcano lifecycles are cryptic, presumably involving tectonic and plumbing changes and perhaps circulation cycles in the mantle wedge, but are remarkably consistent along the arc.

The Holocene chronology of the Mono Craters is well constrained but only recently has 238U-230Th zircon and 40Ar/39Ar dating elucidated the Pleistocene eruptive history. We performed trace element analysis on dated zircon crystal rims and sectioned interiors (using SHRIMP-RG) from 3 rhyolite domes (21, 12.5, and 7 ka) with additional rim data on 5 ashes separated from juvenile pumice clasts in the correlative Wilson Creek Formation (spanning from 62 to 21 ka). Ti-in-zircon (TTi,zrc) thermometry (titania activity from coexisting Fe-Ti oxides) gives temperatures predominantly between 650 degrees C and 750 degrees C, similar to average zircon saturation temperatures (Tzrc,sat). The observation that Tzrc,sat nearly equal TTi,zrc indicates that Mono Craters rhyolite magmas were zircon-saturated and erupted at these temperatures (near water-saturated granite eutectic). Variations in key trace elements are relatively limited overall and zircons display similar REE patterns with generally curved MREE to HREE patterns and prominent negative Eu anomalies. Most of the variation is observed in zircons from older eruptions (62-41 ka). Zircon rims from Ash 17 of the Wilson Creek Formation (59 ka) have elevated Th/U, Eu/Eu*, and Ti and lower Hf compared to Ash 19 (62 ka), which suggests a thermal rejuvenation event between these two eruptions. Zircon rims from Ash 15 (41 ka) are characterized by a trend toward high Hf, at relatively low and relatively constant Ti, and low Eu/Eu*, consistent with rhyolite magma undergoing eutectic-like crystallization just prior to eruption. Zircon surfaces and interiors for the 21, 12.5, and 7 ka dome eruptions have very similar Hf, low Eu/Eu*, low Ti, and low Th/U. This requires zircon crystallization in a very uniform thermal and chemical environment from the latest Pleistocene to Holocene (a feldspar-saturated, crystal mush?).

Van Eaton, Larry G. Mastin, Amanda B. Clarke Evidence for both effusive and explosive volcanism in the geological record of Mars has highlighted questions about the behavior of eruption plumes in the Martian atmosphere. How does the atmospheric structure of Mars (with surface pressures <1% and gravity <40% that of Earth) affect the rise height of volcanic ash and climate-forcing gases? Early modeling studies suggested that Martian plumes may rise significantly higher than their terrestrial equivalents (Wilson and Head, 1994, Rev. Geophys., 32, 221-263), but the validity of these models was called into question by Glaze and Baloga (2002, JGR, 107, 5086). Here we reevaluate the limitations of plume rise models using a steady-state 1-D model for volcanic plumes (Plumeria: Mastin, 2014, JGR, doi:10.1002/2013JD020604). We have used Plumeria to simulate plume heights using a range of atmospheric profiles representing both modern and 'early' Mars, and a range of volcanic eruption rates from 1 x 103 to 1 x 1010 kg s-1. The model assumes perfect coupling of particles with the gas phase in the plume (pseudogas assumption), and Stokes number analysis indicates that this is a reasonable assumption for particle diameters less than 5 mm to 1 micron, depending on the eruption rate. Our estimates of local Knudsen numbers support the continuum assumption for this model. Therefore, we suggest that even simplified fluid dynamics models may provide first-order insights into the rise of volcanic gases - and to some extent, fine ash particles - on Mars. Our results show that volcanic plumes in a modern Martian atmosphere may rise three times higher than those from equivalent eruption rates on Earth, potentially reaching 120 km above the surface. We provide a series of new theoretical eruption rate-plume height scaling relationships that may be useful for considering plume injection heights, climate impacts and global-scale ash dispersal patterns (e.g., Kerber et al., 2013, Icarus, 223, 149-156) in Mars' recent and ancient geological past.

When extensive long-term data sets are available to responsible agencies, volcanic eruptive size, timing and style can usually be successfully forecast using current monitoring data and knowledge of precursory eruptive patterns, enabling the communication of timely forecasts to civil authorities. Experienced agencies, such as Indonesia's Center for Volcanology and Geologic Hazards Mitigation and the USAID-USGS Volcano Disaster Assistance Program, utilize extensive collective experiences with multiple monitoring streams over multiple eruption cycles and across volcano types to successfully forecast eruption size, style and onset, as well as changes in eruptive style and size within ongoing eruptions. The longest-term real-time monitoring parameter commonly available at volcanoes worldwide is seismic data. Seismic data is a direct measure of rate-dependent strain changes in the magmatic system from the deep magmatic input to shallow eruptive processes. Patterns of pre-eruptive earthquakes coupled with other available monitoring data and conceptual models of magma ascent enable short-term forecasting of eruption size, style, and onset. First order event locations, characterization of background seismicity, and changes in earthquake types and energy release are most important to successful eruption forecasting. This study demonstrates how this approach has been used to successfully forecast eruption onsets, changes in eruptive style, and to change alert levels and extend or contract evacuation zones during the ongoing eruption of Sinabung Volcano, Indonesia.

Recent work shows that these interpretations are incorrect. Petrologic, geochemical, isotopic, drill hole, & seismic data indicate that the NV magma system results from arc-related processes at the NW corner of the B&R, where this major extensional province impinges on the Cascades arc. NV rhyolites are geochemically distinct and lower in SiO2 than those to the east where a general NW-younging trend of rhyolite ages has suggested a traveling hotspot -- a consequence instead of propagation of B&R extension. NV lies nearly equal 90 km above the downgoing slab based on seismic evidence (McCrory et al. 2012), nearly equal 15 km deeper than under the Three Sisters (TS) volcanic complex 60 km to the NW on the arc axis. NV & TS exhibit a range of compositions and both have generated rhyodacite with unusually high Na2O contents ( nearly equal 7 wt. %; Mandler et al. 2014), exhibiting similar petrogenetic processes. Silicic lavas and tuffs of the caldera-centric NV make up a significant component ( nearly equal 20% of drill core) of its 600 km3, although basaltic andesite is the dominant composition. Basalts of calcalkaline affinity erupted on the edifice as recently as early Holocene time. These basalts contain petrologic evidence for high pre-eruptive H2O contents, have strong arc-like trace element signatures, and are isotopically Cascadian and distinct from basalts to the east in the B&R that have much higher 3/4He (Graham et al. 2009). NV is one variety of Cascades arc volcano among which are a range of stratovolcanoes including Mt. Baker (15 km3) and Mt. Shasta (500 km3), a Holocene caldera (Crater Lake), and the many basaltic andesite shield volcanoes that make up most of the Oregon High Cascades.

BC that was accreted to North America (NAM) in the early Eocene. Crustal thickness from seismic refraction ranges from 10 to 32 km, with 16 km of pillow and subaerial basalt exposed on the Olympic Peninsula. At 1.7-2.4 x 106 km3, Siletzia is at least 10 times the volume of the Columbia River flood basalts. U-Pb and 40Ar/39Ar ages, global coccolith (CP) zones, and magnetostratigraphy allow correlation of Siletzia with the 2012 geomagnetic polarity time scale. Siletzia was erupted 56-49 Ma (Chron 25-22), and accretion was completed between 51 and 49 Ma in Oregon. Siletzia's composition, great crustal thickness, rapid eruption, and timing of accretion are consistent with formation as an oceanic plateau. Eight m.y. after accretion, margin-parallel extension and regional dike swarms accompanied the voluminous tholeiitic to highly alkalic Tillamook magmatic episode in the forearc (41.6 Ma; CP14a; Chron 19r). We examined the origin of Siletzia and the possible role of a long-lived Yellowstone hotspot (YHS) in GPlates. In most reference frames, the YHS is nearly equal 500km offshore S. OR, near an inferred northeast-striking Kula- Farallon and/or Resurrection-Farallon ridge 60 to 50 Ma. The YHS could have provided the 56-49 Ma source on the Farallon plate for Siletzia, which in the model accretes to NAM by 50 Ma. A sister plateau, the Eocene basalt basement of the Yakutat terrane, now in Alaska, may have formed on the adjacent Kula (or Resurrection) plate and accreted to British Columbia at about the same time. Following accretion, the leading edge of NAM overrode the YHS ca. 42 Ma. The encounter with an active YHS may explain the voluminous 42-34 Ma Tillamook episode and forearc extension. Clockwise rotation of western Oregon about a pole in the backarc has since moved the Tillamook center and underlying Siletzia northward nearly equal 250 km from the likely hotspot track on NAM.

AN - 1861076966; 769918-54 AB - Gases exsolving from magma are a key force that drives eruptive activity, and emissions from Kilauea's East Rift Zone (ERZ) dominated the volcano's gas release from the beginning of the long-running and voluminous Pu'u 'O'o eruption in 1983, through February 2008. In the months prior to the March 2008 onset of eruptive activity within Halema'uma'u Crater, however, SO2 degassing at the summit climbed substantially, and summit gas release has remained elevated since. These unprecedented emissions associated with the new summit eruption effectively began robbing gas from magma destined for Kilauea's ERZ. As a result, ERZ SO2discharge, which had averaged 1,700 +-380 t/d for the previous 15 years, declined sharply and steadily beginning in September, 2008, and reached a new steady low of 380 +- 100 t/d by early 2011. This level persisted through mid-2015. In the years since the late 2008 downturn in ERZ SO2 emissions, there has been an overall slowdown in ERZ eruptive activity. Elevated emissions and effusive activity occurred briefly during the 2011 Kamoamoa fissure eruption and two other outbreaks at Pu'u 'O'o , but otherwise ERZ eruptive activity had waned by 2010, when effusion rates were measured at about half of the long-term rate. Also, the sulfur preserved in ERZ olivine melt-inclusions, which provides a record of pre-eruptive SO2degassing, has steadily declined along with equilibration temperatures of host olivine phenocrysts, since 2008. We suggest that the drop in gas content of magma reaching the ERZ, owing to summit pre-eruptive degassing, has contributed significantly to the downturn in ERZ activity. While SO2 emissions from the ERZ have dropped to sustained levels lower than anything seen in the past 20 years, summit emissions have remained some of the highest recorded since regular measurements began at Kilauea in 1979. Overall, average total SO2 discharge from Kilauea in 2014, summit and ERZ, is still about 50% higher than for the 15 years prior to 2008. The effects of summit pre-eruptive degassing observed at Kilauea may have application at other summit-rift shield volcanoes.

Peak rings can thus be used as probes to study the composition of the lunar crust with depth, which can in turn be compared to models of the formation of the lunar crust. Global surveys conducted to find exposures of nearly pure minerals have found rare lithologies such as norites, troctolites, and anorthosites associated with many basins rings [Yamamoto et al., 2010; 2012, Nakamura et al., 2012], but the abundance of these lithologies relative to the rings as a whole was not determined. Taking a comprehensive approach, Cheek et al. [2013] found that every immature exposure in the inner rook ring of the Orientale basin consists of anorthosite, suggesting that a massive layer of anorthosite is present at the Orientale target site. In this study, we take the approach of Cheek et al. [2013] and examine all the immature exposures in the rings of 14 impact basins. We use Multiband Imager (415-1550 nm) data and radiative transfer modeling to quantify the abundance of the four major lunar minerals in the inner ring of these basins, and determine the dominant lithologies exposed by the rings. We identify the inner ring of these basins using GRAIL crustal thickness data, and derived the mineralogy at a spatial resolution of 80 meters per pixel. Our preliminary results indicate that the dominant lithology in the inner ring of 12 of the 14 basins is anorthosite, with modal plagioclase content ranging between 92-94 wt%, suggesting that a massive layer of anorthosite is widespread under the lunar surface. The dominant lithologies in the other two basins are noritic and gabbroic anorthosites. The other lithologies present in the 14 basins will be investigated next, and the depth of excavation of each of these basin rings as well as the crustal thickness at these sites will be used to determine the composition of the crust with depth.

An integrated hydrologic model (MODFLOW with SWR process) is being developed for the lower San Antonio River Basin in Texas to assess how water use affects the groundwater contribution to stream flow under hypothetical and observed climate scenarios. The basin traverses several dipping aquifer systems and water from these systems is relied on for residential, recreational, industrial, and agricultural uses, as well as oil and gas activities. The current (2015) understanding of interaction between the two hydrologic systems within the basin is limited, but indicates considerable variability in space and time. The modeling analysis is designed to provide improved understanding of spatial and temporal characteristics of interaction under different hydrologic conditions, such as the drought conditions experienced from 2011 through 2013. Due to paucity of data and limited current understanding of interaction between the two hydrologic systems, model results will be inherently uncertain, making uncertainty analysis of paramount importance in the model development and use. As such, linear-based uncertainty analyses, also known as first-order, second-moment analysis, are being used to design the parameterization and objective function prior to the computationally-expensive history-matching process. For this process, we use pyEMU, an open-source python module for linear-based computer model uncertainty analysis. Results show that the prior uncertainty in model inputs yield largely uncertain local-scale interaction estimates. However, by appropriately designing the objective function and parameterization to be aligned with the focus of the modeling analysis, the posterior uncertainty of many local-scale interaction estimates can be reduced.

Zones of fractures, areas of subsurface alteration and pre-eruption hydrologic changes at Old Faithful Geyser and surrounding hydrothermal mounds were observed. Despite being viewed directly by about 3,000,000 people a year, shallow subsurface geologic and hydrologic conditions on and near Old Faithful Geyser are poorly characterized. GPR transects of 5754 ft (1754 m) show strong horizontal to sub-horizontal reflections, which are interpreted as 2.5 to 4.5 meters of sinter. Some discontinuities in reflections are interpreted as fractures in the sinter, some of which line up with known hydrothermal features and some of which have little to no surface expression. Zones with moderate and weak amplitude reflections are interpreted as sinter that has been hydrothermally altered. Temporal changes from stronger to weaker reflections are correlated with the eruption cycle of Old Faithful Geyser, and are interpreted as post-eruption draining of shallow fractures, followed by pre-eruption fracture filling with liquid or vapor thermal fluids.

The petrography and texture of erupted magmas are largely overprinted by processes in the shallow reservoir and conduit. Direct petrological evidence for lower crustal storage and transport is enigmatic but exists in the form of fine-scale crystal zoning in the cores of olivine phenocrysts, in the geochemical heterogeneity of melt inclusions and in fluid inclusion density. The 2007 Father's Day intrusion and eruption occurred at the culmination of a surge in magma supply to the summit reservoir and during a period of heightened CO2 outgassing flux. The erupted lavas provide an opportunity to analyze atypically primitive melts, with > 8.5 wt% MgO in the whole rock, which have undergone relatively little shallow crustal processing. We characterise melt inclusions and their host olivine crystals through a detailed study of olivine morphology, diffusion modelling, and melt and fluid inclusion geochemistry. We show that the melt inclusions preserve primitive geochemical heterogeneity, which we use to reconstruct fractionation, mixing and degassing processes through the crust. We infer timescales and pressures of magma ascent, storage, and CO2 degassing through the crustal plumbing system.

Our work builds upon physical models that rely on plausible sources of exogenous debris and their dynamical rates of decay, the martian cratering record, and preservation of Noachian-Hesperian sedimentary units that have the potential to host organics. Post primary-accretionary scenarios that would have delivered abundant exogenous carbon to Mars can be imagined in two ways: a simple exponential decay with an approximately 100 Myr half-life, or as a "Sawtooth" timeline characterized by both faster-than-exponential decay from primary accretion and reduced total delivered mass. Indications are that a late bombardment spike was superposed on an otherwise broadly monotonic decline from primary accretion, of which two types are explored: a classical "Late Heavy Bombardment" (LHB) peak of impactors centered at ca. 3950 Ma and lasting 100 Myr, and a protracted bombardment typified by a sudden increase in impactor flux at ca. 4240-4100 Ma with a correspondingly longer decay time (400 Myr). Numerical models for each of the four bombardment scenarios explored in this work shows that exogenous organic matter could be a significant component of Noachian (ca. 4200-3700 Ma) and pre-Noachian (4500-4200 Ma) sediments. The discovery of organic-matter in martian sediments will be obfuscated by material of extra-aerological origin. We predict that an earmark for the origin of this carbon would be correlated siderophile element abundances (e.g. Ni, Cr, and the platinoids). A time-dependent compositional relationship of C:HSEs would allow us to derive a chemochronology for pre-Hesperian (pre-3700 Ma) sedimentary units.

Bottom simulating reflectors (BSRs) occur at many gas hydrate sites near the thermodynamic base of the gas hydrate stability zone (GHSZ), and are frequently used to identify possible presence of gas hydrate on a regional scale. To find if drilling a BSR actually increases the chances of finding gas hydrate, we combine an updated dataset of BSR distribution from the Bureau of Ocean Energy Management with a comprehensive dataset of natural gas hydrate distribution as appraised from well logs, covering an area of around 200,000 square kilometers in the northern Gulf of Mexico. The BSR dataset compiles industry 3-D seismic data, and includes mostly good-quality and high-confidence traditional and non-traditional BSRs. Resistivity well logs were used to identify the presence of gas hydrate from over 700 existing industry wells and we have found over 110 wells with likely gas hydrate occurrences. By integrating the two datasets, our results show that the chances of encountering gas hydrate when drilling through a BSR is approximately 42%, while that when drilling outside the BSR is approximately 15%. Our preliminary analysis indicates that a positive relationship exists between BSRs and gas hydrate accumulations, and the chances of encountering gas hydrate increases almost three-fold when drilling through a BSR. One interesting observation is that approximately 58% of the wells intersecting a BSR show no apparent evidence of gas hydrate. In this case, a BSR may occur at sites with no gas hydrate accumulations due to the presence of very low concentration of free gas that is not detected on resistivity logs. On the other hand, in a few wells, accumulations of gas hydrate were observed where no BSR is present. For example in a well in Atwater Valley Block 92, two intervals of gas hydrate accumulation in fractures have been identified on resistivity logs, of which, the deeper interval has 230 feet thick accumulation of gas hydrate with resistivity as high as 9 ohm*m. However, no BSR was observed at the site. We hypothesize that the absence of a BSR may be a result of gas hydrate generated in-situ within the GHSZ from biogenic sources, such that the hydrate interval does not extend to the base of GHSZ.

Earlier studies, based on conventional industry 3D seismic data and logging-while-drilling (LWD) borehole data acquired in 2009, identified general aspects of the regional and local depositional setting along with two gas hydrate-bearing sand reservoirs and one layer containing fracture-filling gas hydrate within fine-grained sediments. These studies also highlighted a number of critical remaining questions. The 2013 high-resolution 2D data fill a significant gap in our previous understanding of the site by enabling interpretation of the complex system of faults and gas chimneys that provide conduits for gas flow and thus control the gas hydrate distribution observed in the LWD data. In addition, we have improved our understanding of the main channel/levee sand reservoir body, mapping in fine detail the levee sequences and the fault system that segments them into individual reservoirs. The 2013 data provide a rarely available high-resolution view of a levee reservoir package, with sequential levee deposits clearly imaged. Further, we can calculate the total gas hydrate resource present in the main reservoir body, refining earlier estimates. Based on the 2013 seismic data and assumptions derived from the LWD data, we estimate an in-place volume of 840 million cubic meters or 29 billion cubic feet of gas in the form of gas hydrate. Together, these interpretations provide a significantly improved understanding of the gas hydrate reservoirs and the gas migration system at GC955.

We have conducted more than 60 aerial surveys with a Cessna 172 using a simple custom wing-mount for consumer grade cameras and SfM photogrammetry to produce orthoimagery and digital elevation models in near-real-time at weekly to monthly time intervals. Multiple lidar flights and ground survey campaigns have provided estimates of both systematic and random error for this uniquely dense dataset. Co-registration of multiple surveys during processing reduces systematic error and allows boot-strapping of subsequently established ground control to earlier flights. Measurements chronicle the erosion of 12 million cubic meters of reservoir sediment and record corresponding changes in channel braiding, wood loading and bank erosion. These data capture reservoir and river channel responses to dam removal at resolutions comparable to hydrologic forcing events, allowing us to quantify reservoir sediment budgets on a per-storm basis. This allows for the analysis of sediment transported relative to rates of reservoir drawdown and river stream power for dozens of intervals of time. Temporal decoupling of peak sediment flux and bank erosion rates is noted from these analyses. This dataset illustrates some of the challenges and opportunities emerging with the advent of big data in remote sensing of earth surface processes.

However, researchers have not tested this method in naturally acidic wetlands that provide breeding habitat for a number of imperiled species, including the frosted salamander (Ambystoma cingulatum), reticulated flatwoods salamanders (Ambystoma bishopi), striped newt (Notophthalmus perstriatus), and gopher frog (Lithobates capito). Our objectives for this study were to develop and optimize eDNA survey protocols and assays to complement and enhance capture-based survey methods for these amphibian species. We collected three or more water samples, dipnetted or trapped larval and adult amphibians, and conducted visual encounter surveys for egg masses for target species at 40 sites on 12 different longleaf pine (Pinus palustris) tracts. We used quantitative PCRs to screen eDNA from each site for target species presence. We detected flatwoods salamanders at three sites with eDNA but did not detect them during physical surveys. Based on the sample location we assumed these eDNA detections to indicate the presence of frosted flatwoods salamanders. We did not detect reticulated flatwoods salamanders. We detected striped newts with physical and eDNA surveys at two wetlands. We detected gopher frogs at 12 sites total, three with eDNA alone, two with physical surveys alone, and seven with physical and eDNA surveys. We detected our target species with eDNA at 9 of 11 sites where they were present as indicated from traditional surveys and at six sites where they were not detected with traditional surveys. It was, however, critical to use at least three water samples per site for eDNA. Our results demonstrate eDNA surveys can be a useful complement to traditional survey methods for detecting imperiled pond-breeding amphibians. Environmental DNA may be particularly useful in situations where detection probability using traditional survey methods is low or access by trained personnel is limited.

Between 1982 and 2012, 12 point-transect distance-sampling surveys were conducted to assess bird population status. Surveys did not consistently sample the entire island; thus, we used a ratio estimator to estimate bird abundances in strata not sampled during every survey. Trends in population size were reliably estimated for 11 of 13 bird species, and 7 species declined over the 30-y time series, including the island collared-dove Streptopelia bitorquata, white-throated ground-dove Gallicolumba xanthonura, Mariana fruit-dove Ptilinopus roseicapilla, collared kingfisher Todiramphus chloris orii, Micronesian myzomela Myzomela rubratra, black drongo Dicrurus macrocercus, and Mariana crow Corvus kubaryi. The endangered Mariana crow (x super(-) = 81 birds, 95% CI 30-202) declined sharply to fewer than 200 individuals in 2012, down from 1,491 birds in 1982 (95% CI = 815-3,115). Trends increased for white tern Gygis alba, rufous fantail Rhipidura rufifrons mariae, and Micronesian starling Aplonis opaca. Numbers of the endangered Rota white-eye Zosterops rotensis declined from 1982 to the late 1990s but returned to 1980s levels by 2012, resulting in an overall stable trend. Trends for the yellow bittern Ixobrychus sinensis were inconclusive. Eurasian tree sparrow Passer montanus trends were not assessed; however, their numbers in 1982 and 2012 were similar. Occupancy models of the 2012 survey data revealed general patterns of land cover use and detectability among 12 species that could be reliably modeled. Occupancy was not assessed for the Eurasian tree sparrow because of insufficient detections. Based on the 2012 survey, bird distribution and abundance across Rota revealed three general patterns: 1) range restriction, including Mariana crow, Rota white-eye, and Eurasian tree sparrow; 2) widespread distribution, low abundance, including collared kingfisher, island collared-dove, white-throated ground-dove, Mariana fruit-dove, white tern, yellow bittern, black drongo, and Micronesian myzomela; and 3) widespread distribution, high abundance, including rufous fantail and Micronesian starling. The Mariana crow was dispersed around the periphery of the island in steep forested land-cover types. In contrast, the Rota white-eye was restricted to the high-elevation mesa. Only for the white-throated ground-dove was there a significant difference among cover types, with lower occupancy in open field than in forested areas. Vegetation was included in the best-fit occupancy models for yellow bittern, black drongo, Micronesian myzomela, and Micronesian starling, but vegetation type was not a significant variable nor included in the top models for the remaining five species: white tern, island collared-dove, Mariana fruit-dove, collared kingfisher, and rufous fantail. Given declining population trends, the Rota bird-monitoring program could benefit from establishing threshold and alert limits and identifying alternative research and management actions. Continued monitoring and demographic sampling, in conjunction with ecological studies, are needed to understand why most bird species on Rota are declining, identify the causative agents, and assess effectiveness of conservation actions, especially for the Mariana crow.

Few studies on the Pacific coast of North America have modeled sea-level rise marsh susceptibility at a scale relevant to local wildlife populations and plant communities. Here, we use a novel approach in developing an empirical sea-level rise ecological response model that can be applied to key management questions. Calculated elevation change over 13 y for a 324-ha portion of San Pablo Bay National Wildlife Refuge, California, USA, was used to represent local accretion and subsidence processes. Next, we coupled detailed plant community and elevation surveys with measured rates of inundation frequency to model marsh state changes to 2100. By grouping plant communities into low, mid, and high marsh habitats, we were able to assess wildlife species vulnerability and to better understand outcomes for habitat resiliency. Starting study-site conditions were comprised of 78% (253-ha) high marsh, 7% (30-ha) mid marsh, and 4% (18-ha) low marsh habitats, dominated by pickleweed Sarcocornia pacifica and cordgrass Spartina spp. Only under the low sea-level rise scenario (44 cm by 2100) did our models show persistence of some marsh habitats to 2100, with the area dominated by low marsh habitats. Under mid (93 cm by 2100) and high sea-level rise scenarios (166 cm by 2100), most mid and high marsh habitat was lost by 2070, with only 15% (65 ha) remaining, and a complete loss of these habitats by 2080. Low marsh habitat increased temporarily under all three sea-level rise scenarios, with the peak (286 ha) in 2070, adding habitat for the endemic endangered California Ridgway's rail Rallus obsoletus obsoletus. Under mid and high sea-level rise scenarios, an almost complete conversion to mudflat occurred, with most of the area below mean sea level. Our modeling assumed no marsh migration upslope due to human levee and infrastructure preventing these types of processes. Other modeling efforts done for this area have projected marsh persistence to 2100, but our modeling effort with site-specific datasets allowed us to model at a finer resolution with much higher local confidence, resulting in different results for management. Our results suggest that projected sea-level rise will have significant impacts on marsh plant communities and obligate wildlife, including those already under federal and state protection. Comprehensive modeling as done here improves the potential to implement adaptive management strategies and prevent marsh habitat and wildlife loss in the future.

Measurements were generated over 20 hours on March 23-24, 2015 using two broadband three-component seismometers placed on the bridge, and compared to concurrent data from nearby reference stations 20 and 220 m distant. We identified seven distinct modes of vibration for Rainbow Bridge between 1 and 6 Hz. Data for each resonant frequency was then analyzed to determine the frequency-dependent polarization vector in an attempt to clarify mode shapes; e.g. the fundamental mode represents out-of-plane horizontal flexure. We compared experimental data to results of 3D numerical modal analysis, using a new photogrammetric model of Rainbow Bridge generated in this study imported into COMSOL Multiphysics. Results compare well with measured data for seven of the first eight modeled modes, matching vibrational frequencies and polarization orientations generally within 10%. Only predicted mode 6 was not explicitly apparent in our experimental data. Large site-to-reference spectral ratios resolved from experimental data indicate high amplification on the bridge as compared to nearby bedrock.

Although much effort has been spent to assess and predict changes in surface-water resources, little has been done to understand how climatic events and changes affect groundwater resources. This study focuses on quantifying the effects of large quasi-decadal groundwater recharge events on groundwater in the northern Utah portion of the Great Basin for the period 1960 to 2013. Groundwater-level monitoring data were analyzed with climatic data to characterize climatic conditions and frequency of these large recharge events. Using observed water-level changes and multivariate analysis, five large groundwater recharge events were identified within the study area and period, with a frequency of about 11 to 13 years. These events were generally characterized as having above-average annual precipitation and snow water equivalent and below-average seasonal temperatures, especially during the spring (April through June). Existing groundwater flow models for several basins within the study area were used to quantify changes in groundwater storage from these events. Simulated groundwater storage increases per basin from a single event ranged from about 115 Mm (super 3) (93,000 acre-feet) to 205 Mm (super 3) (166,000 acre-ft). Extrapolating these amounts over the entire northern Great Basin indicates that even a single large quasi-decadal recharge event could result in billions of cubic meters (millions of acre-feet) of groundwater recharge. Understanding the role of these large quasi-decadal recharge events in replenishing aquifers and sustaining water supplies is crucial for making informed water management decisions.

AN - 1832727882; 2016-089271 AB - It is well established that groundwater pumping affects surface-water availability by intercepting water that would otherwise discharge to streams and/or by increasing seepage losses from stream channels. Conversely, surface-water management affects groundwater availability by altering the timing, location, and quantity of groundwater recharge and pumping. Analyses of climate change impacts on water resources, however, often fail to account for these interactions, in large part due to a lack of modeling tools capable of simulating interactions between surface-water and groundwater management and use. Here we use a modified version of the MODFLOW One Water Hydrologic Flow Model (MODFLOW-OWHM) to evaluate the role of feedbacks between surface-water and groundwater management and use in the context of climate change impact and adaptation studies. This modified version of MODFLOW-OWHM was developed by USBR and USGS by incorporating a fully-integrated surface-water operations module within MODFLOW-OWHM. We use a hypothetical) test case to compare direct and indirect effects of climate change on surface-water and groundwater resources. We define direct effects as changes in groundwater and surface-water conditions resulting from the hydrologic response to climate change (e.g., driven by changes in runoff, recharge, and demands resulting directly from climate change); we define indirect effects as changes arising from the anthropogenic response to direct effects (e.g., driven by changes in groundwater pumping in response to climate-driven changes in water demands or surface water supplies). Results demonstrate that indirect effects on groundwater from changes in demand can outweigh direct effects from changes in supply-viz., indirect effects of increased groundwater pumping due to decreasing surface water supplies can be greater than direct effects of decreasing groundwater recharge. Moreover, under some conditions, indirect effects from changes in groundwater use, and subsequent changes in baseflow and seepage, can significantly exacerbate the direct effects of climate change on surface water. These results, while limited to a simple test case, underscore the importance of accounting for the coupled response of surface-water and groundwater management in climate change analyses.

Volcanic geothermal areas are often too large and inaccessible for only field-based thermal monitoring, so thermal infrared (TIR) remote sensing tools are also used. High resolution (sub-meter) airborne TIR imagery can be used for detailed, quantitative analyses of small, subtle geothermal features. Airborne data acquisitions have the advantage of being able to be acquired under ideal conditions (e.g., predawn, cloud-free), but the disadvantage of high costs - thus precluding high-frequency monitoring. Satellite-based TIR data from the Landsat 8 platform are freely available and can be acquired regularly for change detection, but are acquired with coarser spatial resolution (e.g., 100-m pixels), and thus are not as sensitive to subtle thermal characteristics. Two geothermal areas with clear, nighttime TIR data from nearly concurrent (within days) airborne and spaceborne instruments were investigated: Norris Geyser Basin in Yellowstone National Park, WY; and the Casa Diablo geothermal field, near Mammoth Lakes, CA. At Norris Geyser Basin, the area covered by high-resolution airborne TIR imagery is almost entirely geothermally heated ground, with hundreds of fumaroles, hot springs, and thermal drainages--although some non-geothermal background is exposed. With the coarser resolution Landsat 8 data, there are thermal variations within the smaller area covered by the airborne data, but the entire area appears to be thermally anomalous with respect to the non-geothermal background outside the basin. In the geothermal field around the Casa Diablo geothermal site, there are numerous, small areas of geothermal heating that are clearly distinguishable above the background by the high-resolution airborne nighttime TIR imaging. Most of the thermal radiance contrast in the Landsat 8 TIR image is due to slope, surface cover type, and albedo, but there are some very subtle variations in thermally emitted radiance that are spatially coincident with the thermally anomalous areas identified with the airborne data.

Here we report on the morphodynamic responses of the Elwha River delta to large increases in river sediment loads from the removal of two large dams beginning in 2011. The dam removal project exposed approximately 30 million tons of sediment stored within the former reservoirs to natural erosion by the river, and roughly half of this reservoir sediment was eroded during the first four years of the project. Coastal surveys with GPS-based mapping systems, sonar, and aerial photography have revealed that the Elwha River mouth has expanded seaward by approximately 500 m with the introduction of new supplies of sediment. Approximately 3.5 million cubic meters (or approximately 5 million tonnes) of sediment were deposited at the river mouth delta between 2011 and 2015. This newly deposited sediment has been shaped by waves and currents into a series of dynamic bars that have greatly expanded the estuarine habitats of the delta.

From these removals, common findings have begun to emerge: (1) Rivers are resilient, showing rapid geomorphic and sedimentary response to dam removals, especially when removals are sudden rather than prolonged, and where rivers have adequate stream power. Rivers can rapidly evacuate large percentages of stored reservoir sediment (> or =40% within one year)-particularly where sediment is coarse-grained (sand and gravel), and can move evacuated sediment long distances (>20 km downstream) within a year, given sufficient transport capacity. The channel downstream typically takes months to years-not decades-to achieve a degree of stability within its natural range of variability. (2) Modest flows can erode large amounts of reservoir sediment and move it downstream. Large floods are not required to move substantial sediment volumes, especially from non-cohesive reservoir deltas. Once the most easily accessed sediment is eroded, however, larger floods can continue to access the remnant reservoir sediment and redistribute it downstream. Portions of the redistributed sediment remain (up- and downstream of the dam site), shaping a new landscape. (3) Dam height, sediment volume, and sediment grain size and cohesion strongly influence response to dam removal. Although removals of small dams with little stored sediment are more common, removals of large dams (> or =10 m) with major sediment releases have had longer-lasting and more widespread downstream effects. (4) Downstream valley morphology and hydrology strongly influence the distribution of released sediment. Bedrock confinement versus wide alluvial reaches, downstream channel gradient, locations and depths of channel pools, locations and geometries of existing channel bars, position of the dam within a watershed, and flood occurrence all influence the downstream fate of released sediment. These findings increase understanding of the physical response to dam removal, set the stage for anticipating habitat and ecological changes, and allow better predictions for the outcomes of future dam removals.

The river downstream from the dams is gravel bedded with a pool-riffle morphology. The river flows 20 km to the marine environment through a riparian corridor lined with large wood and having relatively few anthropogenic alterations. This moderately natural pre-dam-removal condition afforded an unprecedented opportunity to study river response to an anticipated massive sediment release. Four years into the project, 12 million m (super 3) of sediment eroded from the former reservoirs with about 90% of the total load transported to the marine environment. Annualized sediment discharge was as great as 20 times the background natural load. Initial river response to the arrival of the first large sediment pulse was the nearly complete filling of the river's previously sediment-starved pools, widespread filling of side channels, and increased braiding index. In year 2, during maximum aggradation, the river graded to a plane-bedded system, efficiently conveying sediment to the marine environment. Modest peak flows (<2-yr return period) in year 2 promoted sediment transport but caused little large-scale geomorphic disturbance by channel migration or avulsions. As the river processed the sediment pulse, pools returned and the braiding index decreased in years 3-4. Higher peak flows in year 4 caused localized channel widening and migration but no major avulsions. Gauging indicated sand dominated the first stages of sediment release, but fluvial loads coarsened through time with progressive arrival of larger material. The literature suggests the Elwha River sediment wave should have evolved through dispersion with little translation. However, morphologic measurements and data from a stage-gauge network indicated patterns of deposition, sediment transport, and sediment-wave evolution were heterogeneously complex, challenging our efforts to classify the sediment wave in terms of simple dispersion or translation.

These dams also restricted the downstream movement of sediment, wood, and other organic materials to the lower river and estuary. Populations of all Pacific salmon species and steelhead in the Elwha became critically low, habitat complexity decreased below the dams, and downstream coastal habitats became sediment starved. Simultaneous deconstruction of the two dams began in September 2011 was completed in September of 2014. The recent removal of the dams has been an opportunity to explore linkages among changes in sediment supply, salmonid populations, and ecosystem attributes. Preliminary findings focus on the delivery of millions of metric tonnes of sediment to the main river, its floodplain, and nearshore, the re-establishment of a natural wood delivery regime, the re-colonization of the upper watershed by anadromous fish, insights into functional relationships among salmonid populations and life history strategies, and the associated effects of all these elements on the aquatic and terrestrial foodwebs. This talk will provide an overview of the Elwha restoration project, and highlight recent changes observed during dam removal.

This can result in implementing structural controls or other interventions at a site to avoid anticipated negative effects, sometimes even if a given concern is not warranted. We used a newly available dam removal science database and other information sources to explore seven frequently raised issues we call "Common Management Concerns" (CMCs), investigating their occurrence and the contributing biophysical controls. We describe these controls to enable managers to better assess if further analyses are warranted at their sites before interventions are planned and implemented. The CMCs addressed are: rate and degree of reservoir sediment erosion; drawdown impacts on local water infrastructure; excessive channel incision; downstream sediment aggradation; elevated turbidity; colonization of reservoir sediments by non-native plants; and expansion of invasive fish. The relative dearth of case studies available for many CMCs limited the generalizable conclusions we could draw about prevalence, but the available data and established understanding of relevant processes revealed important biophysical phenomena controlling the likelihood of CMC occurrence. To assess CMC risk, we recommend managers concurrently evaluate if site conditions suggest the ecosystem, infrastructure, or other human uses will be negatively affected if the biophysical phenomenon producing the CMC occurs. We show how many CMCs have one or more controls in common, facilitating the identification of multiple risks at a site, and demonstrate why CMC risks should be considered in the context of other important factors like watershed disturbance history, natural variability, and dam removal tradeoffs. Better understanding CMCs and how to evaluate them will enable practitioners to avoid unnecessary interventions and thus maximize opportunities for working with natural processes to restore river function.

Its low strength relative to other common fault gouge minerals is important in many models of fault rheology. However, the coefficient of friction is not well constrained in the literature due to the difficulty of establishing fully drained or fully dried states in the laboratory. For instance, in some reported studies, samples were either partially saturated or possibly over pressured, leading to wide variability in reported shear strength. In this study, the coefficient of friction, mu , of both saturated and oven-dried (at 150 degrees C) Na-montmorillonite was measured at normal stresses up to 680 MPa at room temperature and shortening rates from 1.0 to 0.01 mu m/s. Care was taken to shear saturated samples slowly enough to avoid pore fluid overpressure in the clay layers. Coefficients of friction are reported after 8 mm of axial displacement in a triaxial apparatus on saw-cut samples containing a layer of montmorillonite gouge, with either granite or sandstone driving blocks. For saturated samples, mu increased from around 0.1 at low pressure to 0.25 at the highest test pressures. In contrast, values for oven-dried samples decreased asymptotically from approximately 0.78 at 10 MPa normal stress to around 0.45 at 400-680 MPa. While wet and dry strengths approached each other with increasing effective normal stress, wet strength remained only about half of the dry strength at 600 MPa effective normal stress. The increased coefficient of friction can be correlated with a reduction in the number of loosely bound lubricating surface water layers on the clay platelets due to applied normal stress under saturated conditions. The steady-state rate dependence of friction, a-b, was positive and dependent on normal stress. For saturated samples, a-b increased linearly with applied normal stress from nearly equal 0 to 0.004, while for dry samples a-b decreased with increasing normal stress from 0.008 to 0.002. All values were either neutral or rate strengthening, indicating a tendency for stable sliding.

The Mattole River does not follow the classic river "concave-up" profile. Instead, the river headwaters have wide valleys of low gradient fill, cut and strath terraces with deeply incised active channels. In fact, the river has a "convex-up" profile with a low gradient headwater leading to a higher gradient midcourse. Terrace formation in the upper headwater region of the Mattole River records times of disequilibrium of channel profile and incision as the river responds to changes that are, in large part, due to the passage of the northwardly migrating, thermally buoyant MTJ. In order to investigate the distribution and relative ages of terraces, detailed surveys of terrace surfaces and bedrock strath positions were conducted along four headwater tributaries: Thompson Creek, Baker Creek, Lost River and Ancestor Creek. Additionally, across the terraces, hand borings were excavated to bedrock to provide a three dimensional image of terrace thickness. Terrace morphology and stratigraphy provide information on terrace forming mechanisms and timing. This study includes high-resolution geomorphic data regarding the relation of Mattole headwater terraces to the MTJ, as well as provides more temporal information about the fluvial system's response to the ongoing northward migration of the MTJ.

In contrast to many other moderate-to-large historical events, the causative fault is clearly established. Published magnitude estimates have been fairly consistent, ranging from 6.8 to 7.2, with 95% confidence limits including values as low as 6.5. The magnitude is of particular importance for assessment of seismic hazard associated with the Hayward fault and, more generally, to develop appropriate magnitude-rupture length scaling relations for partially creeping faults. The recent reevaluation of archival accounts by Boatwright and Bundock (2008), together with the growing volume of well-calibrated intensity data from the U.S. Geological Survey "Did You Feel It?" (DYFI) system, provide an opportunity to revisit and refine the magnitude estimate. In this study, we estimate the magnitude using two different methods that use DYFI data as calibration. Both approaches yield preferred magnitude estimates of 6.3-6.6, assuming an average stress drop. A consideration of data limitations associated with settlement patterns increases the range to 6.3-6.7, with a preferred estimate of 6.5. Although magnitude estimates for historical earthquakes are inevitably uncertain, we conclude that, at a minimum, a lower-magnitude estimate represents a credible alternative interpretation of available data. We further discuss implications of our results for probabilistic seismic-hazard assessment from partially creeping faults.Online Material: Table of locations with intensity assignments.

Central to Lake Clark National Park and Preserve, Lake Clark is an important nursery lake for sockeye salmon (Oncorhynchus nerka) in the headwaters of Bristol Bay, Alaska, the most productive wild salmon fishery in the world. Lake Clark water clarity is seasonally influenced by a dynamic glacier fed sediment plume. We reconstructed lake-wide water clarity for Lake Clark using the Landsat TM and ETM+ Climate Data Record archive. Our study period consisted of May - October for 1985-2015. We found 151 (98 partial- and 53 whole-lake) Landsat scenes that captured the lake and/or sediment plume. Water clarity fluctuated on an annual basis with specific conditions common to certain months. Plume development and peak turbidity dates could be estimated for a number of years and mid-season gyres appear to represent wind-induced mixing of lake water. Our results showed short term (sub-decadal) trends in water clarity but little to no long term trend between 1991 and 2014. We did, however, detect interannual variation that exhibited a non-significant (r (super 2) = 0.20) but positive correlation (r = 0.20) with regional mean summer air temperature and found the month of May exhibited a significant positive trend (r (super 2) = 0.68, p-value = 0.02) in turbidity between 2000 and 2014. These results are important because reductions in water clarity within Alaska lake systems as a result of increased glacial runoff have been shown to reduce salmon production via reduced abundance of preferred prey items of juvenile salmon, such as zooplankton and macroinvertebrates.

In northern Alaska, marine deposits now 5-10 m above modern sea level are assigned to this time period and termed the Pelukian transgression (PT). Complicating this interpretation is the possibility that an intra-Stage 5 ice shelf extended along the Alaskan coast, causing isostatic depression along its grounded margins, which caused RSL highs even during periods of low, global RSL. Here we use optically stimulated luminescence (OSL) to date inferred PT deposits on the Beaufort Sea coastal plain. A transition from what we interpret to be lagoonal mud to sandy tidal flat deposits lying nearly equal 2.75 m asl dates to 113+/-18 ka. Above this, a 5-m thick gravelly barrier beach dates to 95 +/- 20 ka. This beach contains well-preserved marine molluscs, whale vertebrae, and walrus tusks. Pleistocene-aged ice-rich eolian silt (yedoma) blanket the marine deposits and date to 57.6 +/-10.9 ka. Our interpretation of this chronostratigraphy is that RSL was several meters higher than today during MIS 5e, and lagoons or brackish lakes were prevalent. Gravel barrier beaches moved onshore as local RSL rose further after MIS 5e. The error range of the OSL age of the barrier-beach unit spans the remaining four substages of MIS 5; however, the highstand of RSL on this arctic coastline appears to occurr after the warmest part of the last interglacial and appears not to be coeval with the eustatic maximum reached at lower latitudes during MIS 5. One possibility is that RSL along the Beaufort Sea coast was affected by isostatic depression caused by an ice shelf associated with widespread, intra-Stage 5 glaciation that was out of phase with lower latitude glaciation and whose extent and timing remains enigmatic.

Previous work in the Bahamas shows that coarse-grained, high-energy event layers in carbonate bank margin sediments: (1) closely track recent historic hurricane events and (2) that the sensitivity of this proxy may be less affected by the deglacial changes in sea level that have limited our ability to reconstruct past hurricane activity using overwash records from back-barrier beach settings. Here we present a record of storm triggered turbidite deposition from a suite of well dated (e.g. Lynch-Stieglitz et al., 2011, Paleoceanography) jumbo piston cores taken offbank (300-500 mbsl) the Dry Tortugas, Florida, that spans abrupt transitions in North Atlantic sea surface temperature and thermohaline circulation during the Younger Dryas (12.9 - 11.5 kyr BP). This record, along with General Circulation Model output (TraCE: NCAR-CGD), indicates strong hurricane activity may have occurred along Southeastern US coasts through this interval despite considerably colder North Atlantic SSTs.

Incision following the 2011-2014 removal of Elwha (34 m high; Lake Aldwell reservoir) and Glines Canyon (64 m; Lake Mills reservoir) Dams on the Elwha River in Washington State exposed 85+ years accumulation of reservoir sediment in cross section, creating the first known opportunity to characterize post-impoundment sediments of a large reservoir in situ. In Lake Mills, the upstream reservoir, the Elwha River deposited an estimated 1.56x10 (super 6) m (super 3) sediment primarily in a steep-fronted, Gilbert-style delta, while deposition in downstream Lake Aldwell comprised only nearly equal 3.0x10 (super 6) m (super 3) sediment, deposited broadly in an elongate, low-angle delta. Allochthonous carbon is primarily preserved in delta foresets and complexly-bedded prodelta sands, with secondary lenses of coarse-grained organics deposited as channel-lag in migrating topset channels. Organic units tend to be coarse-grained, open-framework lenses and beds consisting of well-preserved branches, cones, and needles in the topset and foreset beds, while prodelta sands consist of well-sorted, well-preserved needles and leaves associated with fine sands and silts. Compared to Lake Mills, Lake Aldwell's delta deposits are lower angle and have finer, more organic-rich topset beds. Lacustrine beds in the main body of the reservoir are dominated by mineral sediments. Taking the average total organic carbon (TOC) content and geometry of individual facies provides a first-order estimate of the total organic carbon load in the reservoir sediments, and provides insight into the spatial variability of carbon deposition, a key challenge in understanding the carbon footprint of large water reservoirs.

Peatlands account for nearly 30 percent of the soil organic carbon (C) within the northern permafrost region, storing roughly 275 Pg of organic C, equivalent to over one-third of the C currently in the atmosphere. Much uncertainty remains about how much peat C is lost, the controls on loss, and what the long-term C balance is following permafrost thaw. Here, we explore some of these questions using both a chronosequence and mass-balance modeling approach, as well as using paleoecological reconstructions to better understand the timing of peatland development and permafrost aggradation and degradation over the Holocene. Carbon from the formerly frozen permafrost plateau is released to the atmosphere upon permafrost thaw on the order of years to decades, and long-term accumulation of post-thaw bog peat leads to carbon uptake over centuries to millennia. We also show that understanding the depositional environment of the peat can help explain greater or lower carbon losses following thaw. In order to place these results into the context of permafrost peatlands across the northern high latitudes, we synthesized existing paleoecological reconstructions from peat cores and demonstrate that most peatlands that either currently contain permafrost or have experienced recent thaw (last few decades), formed permafrost epigenetically or quasi-epigenetically, with most permafrost aggradation occurring during Holocene neoglacial cooling and the Little Ice Age.

Extraction of a single environmental variable (e.g., temperature) requires poorly supported assumptions that introduce additional error and results in loss of valuable information contained within the assemblage. Conversely, temperatures generated by a numerical climate model for a given locale do not have any associated error. Thus, comparison of faunal assemblage-based temperature estimates with simulated temperatures from GCMs is an oversimplification of a complex system. It is critical that like data sets are compared. For example, proxies for temperature may estimate conditions at the surface or at various depths or during particular seasons. These estimates are not directly comparable, and pooling Mg/Ca, alkenone and assemblage-based estimates of ocean temperature is inherently wrong. A more appropriate data-model comparison would involve comparing the faunal assemblage found in a core sample to one estimated by a paleoecological model driven by a GCM. An ideal comparison would score a suite of environmental factors gleaned from a faunal assemblage with those simulated by a GCM. Quantification of these factors, however, is not practical in some cases. A paradigm shift in marine paleoclimate reconstruction is overdue, and comparison of paleoenvironments to model simulations requires a revised approach. The PRISM4 reconstruction presents a holistic and nuanced interpretation of multidimensional oceanographic processes and responses that is lost when reduced to a single variable such as temperature. Beyond the global approach, we incorporate regional climate dynamics with emphasis on processes, integrating multiple environmental proxies wherever available, to better characterize the environment. A more appropriate methodology is needed to adequately compare these robust and intricate paleoenvironmental reconstructions to those simulated by GCMs. JF - American Geophysical Union Fall Meeting AU - Dowsett, H J AU - Robinson, M M AU - Salzmann, U AU - Anonymous Y1 - 2015/12// PY - 2015 DA - December 2015 SP - Abstract PP43B EP - 2267 PB - American Geophysical Union, Washington, DC VL - 2015 KW - 15:Miscellaneous UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1807507246?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=American+Geophysical+Union+Fall+Meeting&rft.atitle=Toward+a+better+approach+to+data-model+comparison&rft.au=Dowsett%2C+H+J%3BRobinson%2C+M+M%3BSalzmann%2C+U%3BAnonymous&rft.aulast=Dowsett&rft.aufirst=H&rft.date=2015-12-01&rft.volume=2015&rft.issue=&rft.spage=&rft.isbn=&rft.btitle=&rft.title=American+Geophysical+Union+Fall+Meeting&rft.issn=&rft_id=info:doi/ LA - English DB - GeoRef N1 - Conference title - American Geophysical Union 2015 fall meeting N1 - Copyright - GeoRef, Copyright 2016, American Geosciences Institute.

The recent appearance of holes on the stoss slope of Mount Baldy at the Indiana Dunes National Lakeshore provided an opportunity for study of such features. Mount Baldy is a large parabolic dune that is rapidly migrating onshore over a late Holocene landscape with stabilized relict parabolic dunes that supported oak (Quercus spp.) trees visible on the 1939 aerial photo. Individual holes were mapped to locations on the dune surface that would directly overlie the arm of a buried relict parabolic dune. Analyses of buried trees and surrounding sediment indicated that saprotrophic wood decay fungi continue to actively decompose trees after burial and biomineralization of a calcium-carbonate-rich cement occurs at the contact between organic material and sands. Scanning electron microscopy of the cement showed neoformed authigenic minerals and organic structures consistent in morphology with fungal hyphae. We propose that, within the dune, portions of the decayed trees progressively collapse and infill, and open holes are temporarily stabilized by the calcium-carbonate-rich cement. Further, holes can exist undetected at the surface, covered by a thin veneer of sand. Migrating dune systems are observed in many coastal and inland areas. Ongoing work must address the relative contributions of individual environmental factors on the formation of dune decomposition chimneys, including the biomineralization of cement, sand mineralogy, rate of dune movement, tree species, climate, and the composition of fungal communities.

This was due to the lack of information about ecosystem properties such as soil and vegetation characteristics at high spatial resolution. In recent years, the National Park Service (NPS) has carried out several projects mapping ecotype and soil in the Arctic parks from Landsat satellite data at 28.5 m spatial resolution. We used these detailed ecotype and soil maps along with downscaled climate forcing from the IPCC and Climatic Research Unit, University of East Anglia (UK) to model near-surface permafrost distribution, temperature and active layer thickness at decadal time scale from the present through 2100 at 28.5 m resolution for the five Arctic national parks in Alaska: Gates of the Arctic National Park and Preserve, Noatak National Preserve, Kobuk Valley National Park, Cape Krusenstern National Monument, and Bering Land Bridge National Preserve. Our results suggest the near-surface permafrost distribution, i.e. permafrost immediately below the active layer, will likely decrease from the current 99% of the total park area (five parks combined) to 89% by 2050 and 36% by 2100. The near-surface permafrost will likely continue to exist in the northern half of the Gates of the Arctic and Kobuk Valley parks, and in majority of the Noatak preserves by 2100, though its temperature will be up to 5 degrees C warmer than the present at certain places. Taliks will likely occupy the ground below the active layer in rest of the park areas. These products fill an essential knowledge and data gap and complement research of other Arctic disciplines such as ecosystem modeling, hydrology and soil biogeochemistry.

We separate the finite-element integration into a discretization-specific portion and discretization-independent pointwise functions associated with the governing equations. The discretization-specific portion is designed to accommodate arbitrary order finite elements and multiple implementations for optimization targeting specific hardware (e.g., CPU and GPU). The pointwise functions encapsulate the physics, including the governing equations and rheologies. Users can easily extend the code by adding new pointwise functions to implement different rheologies and/or governing equations. PyLith currently includes pointwise functions for quasi-static and dynamic elasticity for several elastic, viscoelastic, and elastoplastic rheologies. We plan to add pointwise functions for coupling of elasticity with fluid flow and incompressible elasticity. Tight integration with the Portable, Extensible Toolkit for Scientific Computation (PETSc) provides support for a wide range of linear and nonlinear solvers and time-stepping algorithms.

This study focused on characterizing and understanding summertime air quality in the Northern Front Range Metropolitan Area (NFRMA), with an emphasis on ozone and its precursors. Exceedances of the National Ambient Air Quality Standard (NAAQS) for ozone occur regularly in the NFRMA during the summertime and impact air quality in Rocky Mountain National Park (ROMO). As part of FRAPPE, the National Park Service supplemented its long-term monitoring at its Longs Peak site ( approximately 9000 ft.) with enhanced trace gas and aerosol measurements; ozone and meteorological measurements were also deployed at a high altitude site off of Trail Ridge Road ( approximately 11,600 ft.). At Longs Peak, a suite of volatile organic compounds (VOCs), including nonmethane hydrocarbons, halocarbons, alkyl nitrates and oxygenated VOCs (OVOCs), were measured using a cryogen-free gas chromatographic system and a proton transfer reaction-mass spectrometer. Additionally, whole air samples were collected along a route from Fort Collins, CO up to Trail Ridge Road several times per week. The transect samples were typically collected during upslope events and aircraft deployment days to characterize air mass composition and to aid in linking the surface and airborne measurements. Ozone distributions from Trail Ridge Road and Longs Peak generally tracked well temporally, with the highest ozone levels measured at the high elevation site; maximum hourly values during FRAPPE were 82 ppb and 79 ppb, respectively. A mixed signature containing both urban and oil and gas emissions was regularly observed in air masses encountered in the park, with elevated ozone and VOC levels measured during upslope events. However, the highest levels of alkanes measured at Longs Peak were associated with oil and gas operations, based on the isopentane to n-pentane ratio. Transect samples and aircraft data collected during an upslope event will be used to assess air mass transport to ROMO and will be compared to species concentrations as modeled by the Comprehensive Air quality Model with Extensions (CAMx). CAMx meteorological inputs will be developed using the Weather Research and Forecasting (WRF) model, with special attention paid to accurately capturing upslope flow.

This paper compares hazard using the new suite of ground motion models (GMMs) relative to hazard using the suite of GMMs applied in the previous version of the maps. The new source characterization models are used for both cases. A previous paper (Rezaeian et al. 2014) discussed the five NGA-West2 GMMs used for shallow crustal earthquakes in the Western United States (WUS), which are also summarized here. Our focus in this paper is on GMMs for earthquakes in stable continental regions in the Central and Eastern United States (CEUS), as well as subduction interface and deep intraslab earthquakes. We consider building code hazard levels for peak ground acceleration (PGA), 0.2-s, and 1,0-s spectral accelerations (SAs) on uniform firm-rock site conditions. The GMM modifications in the updated version of the maps created changes in hazard within 5% to 20% in WUS; decreases within 5% to 20% in CEUS; changes within 5% to 15% for subduction interface earthquakes; and changes involving decreases of up to 50% and increases of up to 30% for deep intraslab earthquakes for most U.S. sites. These modifications were combined with changes resulting from modifications in the source characterization models to obtain the new hazard maps.

The method involves resampling monthly temperature and precipitation from the instrumental record directed by variability indicated by the paleoclimate record. The generated time series of monthly temperature and precipitation are subsequently used as inputs to a monthly water balance model. The methodology is applied to the Upper Colorado River Basin, and results indicate that the methodology reliably simulates water-year runoff, maximum snow water equivalent, and seasonal soil moisture storage for the instrumental period. As a final application, the methodology is used to produce time series of PET, AET, SWE, SMS, and R for the 1404-1905 period for the Upper Colorado River Basin.

The mean value is estimated simultaneously with the mean residence times of the gas and water in the stream by sampling the stream for one or both age tracers, along with dissolved nitrogen and argon at a single location over a period of approximately 12-14 h. The data are fitted to an equation representing the temporal in-stream gas exchange as it responds to the diurnal temperature fluctuation. The efficacy of the method is demonstrated by collecting and analyzing samples at six different stream locations across parts of northern Virginia, USA. The studied streams drain watersheds with areas of between 2 and 122 km super(2) during periods when the diurnal stream temperature ranged between 2 and 5 degree C. The method has the advantage of estimating the mean groundwater residence time of discharge from the watershed to the stream without the need for the collection of groundwater infiltrating to streambeds or local groundwater sampled from shallow observation wells near the stream.

The model must be capable of representing short-timescale hydrodynamics, salinity transport, and groundwater interaction. However, there is also a strong need to adapt these numerical models to hindcast past conditions in order to examine long-term effects on the distribution of vegetation that cannot be determined using only the modern record. Based on parameters developed for a numerical model developed for the recent 1996 to 2004 period, a hindcast model was developed to represent sea level and water management for the period of 1926 to 1932, constrained by the limited hydrology and meteorology data available from the historic past. Realistic hurricane-wind and storm surge representations, required for the hindcast model, are based on information synthesized from modern storm data. A series of simulation scenarios with various hurricane representations inserted into both hindcast and recent numerical models were used to assess the utility of the storm representation in the model and compare the two simulations. The comparison of the hindcast and recent models showed differences in the hydrology patterns that are consistent with known differences in water delivery systems and sea level rise. A 30 lower-resolution spatially variable wind grid for the hindcast produced similar results to the original high-resolution full wind grid representation of the recent simulation. Storm effects on hydrologic patterns demonstrated with the simulations show hydrologic processes that could have a long-term effect on vegetation change. The hindcast simulation estimated hydrologic processes for the 1926 to 1932 period. It shows promise as a simulator in long-term ecological studies to test hypotheses based on theoretical or empirical-based studies at larger landscape scales.

In permafrost influenced terrain, fire may initiate thermokarst development which impacts hydrology, vegetation, wildlife, carbon storage and infrastructure. In this study we differenced two airborne LiDAR datasets that were acquired in the aftermath of the large and severe Anaktuvuk River tundra fire, which in 2007 burned across a proposed road corridor in Arctic Alaska. The 2009 LiDAR dataset was acquired by the Alaska Department of Transportation in preparation for construction of a gravel road that would connect the Dalton Highway with the logistical camp of Umiat. The 2014 LiDAR dataset was acquired by the USGS to quantify potential post-fire thermokarst development over the first seven years following the tundra fire event. By differencing the two 1 m resolution digital terrain models, we measured permafrost thaw subsidence across 34% of the burned tundra area studied, and observed less than 1% in similar, undisturbed tundra terrain units. Ice-rich, yedoma upland terrain was most susceptible to thermokarst development following the disturbance, accounting for 50% of the areal and volumetric change detected, with some locations subsiding more than six meters over the study period. Calculation of rugosity, or surface roughness, in the two datasets showed a doubling in microtopography on average across the burned portion of the study area, with a 340% increase in yedoma upland terrain. An additional LiDAR dataset was acquired in April 2015 to document the role of thermokarst development on enhanced snow accumulation and subsequent snowmelt runoff within the burn area. Our findings will enable future vulnerability assessments of ice-rich permafrost terrain as a result of shifting disturbance regimes. Such assessments are needed to address questions focused on the impact of permafrost degradation on physical, ecological, and socio-economic processes.

At the same time, recruitment and maximum length of trout populations in tail-waters often fluctuate erratically, which negatively affects the value of fisheries. Large recruitment events may increase dispersal downriver where other fish species may be a priority (e.g., endangered species). There is an urgent need to understand the drivers of trout population dynamics in tail-waters, in particular the role of flow management. Here, we evaluate how flow, fish density, and other physical factors of the river influence recruitment and mean adult length in tailwaters across western North America, using data from 29 dams spanning 1-19 years. The mean lengths of adult rainbow and brown trout were influenced by similar flow and catch metrics. Species-specific responses to flow management are likely attributable to differences in seasonal timing of key life history events such as spawning, egg hatching, and fry emergence.

Climate change adds to those historical challenges, but does not, for the most part, introduce entirely new challenges; rather climate change is likely to stress water supplies and resources already in many cases stretched to, or beyond, natural limits. In this context, four iconic river basins offer glimpses into specific challenges that climate change may bring to the West. The Colorado River is a system in which overuse and growing demands are projected to be even more challenging than climate-change-induced flow reductions. The Rio Grande offers the best example of how climate-change-induced flow declines might sink a major system into permanent drought. Finally, California's Bay-Delta system is a remarkably localized and severe weakness at the heart of the region's trillion-dollar economy. It is threatened by the full range of potential climate-change impacts expected across the West, along with major vulnerabilities to increased flooding and rising sea levels.

Study sites were located within Bandelier National Monument and Santa Fe National Forest on the east-facing Pajarito Plateau of the Jemez Mountains in North-Central New Mexico. Across all sites, total understory cover increased several-fold at 3 to 5years post-treatment relative to both pre-treatment condition and control, whereas measures of runoff and sediment production were reduced by an order of magnitude. During the course of post-treatment monitoring, several coincident disturbances (multi-year drought beginning in fall 1999, wildfire in spring 2000 and pinon ips beetle outbreak in 2002) caused widespread vegetation mortality and allowed differential recovery patterns to be documented across treatment and control areas. Response to these unplanned disturbances suggested prior restoration to improve ecohydrologic function of denuded intercanopy locations also primed understory resilience as measured by the relative capacity of restored areas to regain levels of effective cover. Treatment areas affected by drought-beetle tree mortality exceeded pre-drought levels of understory cover within two growing seasons while retaining improved hydrologic function; by contrast, control areas continued to exhibit accelerated runoff and erosion despite temporary improvements in understory cover post-disturbance. Post-fire outcomes suggest that prior restoration also enhanced levels of understory cover post-burn relative to control, despite negative-soil-heating effects from consumed slash.

The use of the term has grown over the past several decades to the point that by now, many disciplines have their own definitions and metrics. In this paper, we aim to provide a context and focus for linkages of resilience to natural resources management. We consider differences and similarities in resilience as presented in several disciplines relevant to resource management. We present a conceptual framework that includes environmental drivers, management interventions, and system responses cast in terms of system resilience, as well as a process for decision making that allows learning about system resilience through experience and incorporation of that learning into management. We discuss the current state of operational management for resilience, and suggest ways to improve it. Finally, we describe the challenges in managing for resilience and offer some recommendations about the scientific information needs and scientific issues relevant to making resilience a more meaningful component of natural resources management.

Three-hourly winds simulated by four separate GCMs were used to generate an ensemble of wave conditions for a recent historical time-period (1976-2005) and projections for the mid and latter parts of the 21st century under two radiative forcing scenarios (RCP 4.5 and RCP 8.5), as defined by the fifth phase of the Coupled Model Inter-comparison Project (CMIP5) experiments. Comparisons of results from historical simulations with wave buoy and ERA-Interim wave reanalysis data indicate acceptable model performance of wave heights, periods, and directions, giving credence to generating projections. Mean and extreme wave heights are projected to decrease along much of the North American west coast. Extreme wave heights are projected to decrease south of 50 degree N and increase to the north, whereas extreme wave periods are projected to mostly increase. Incident wave directions associated with extreme wave heights are projected to rotate clockwise at the eastern end of the Aleutian Islands and counterclockwise offshore of Southern California. Local spatial patterns of the changing wave climate are similar under the RCP 4.5 and RCP 8.5 scenarios, but stronger magnitudes of change are projected under RCP 8.5. Findings of this study are similar to previous work using CMIP3 GCMs that indicates decreasing mean and extreme wave conditions in the Eastern North Pacific, but differ from other studies with respect to magnitude and local patterns of change.

Soils were collected from mature forests, patches of Phalaris arundinacea, an exotic grass, and areas restored to early successional forest (unbrowsed and browsed) in the Upper Mississippi River floodplain. Samples were collected across an elevation gradient and along the descending limb of the hydrograph to test for effects of flooding. In all three forest types, soil properties were less favorable for nitrification as elevation increased, due to decreasing organic matter, porosity, total nitrogen, and temperature. In contrast, Phalaris maintained high soil organic matter and porosity as floodplain elevation increased. Corresponding with the differences in soil properties found in forested plots, the highest rates of potential gross nitrification were found in the lower elevation sites immediately following the spring flood (1-8 days post inundation). These high rates were later followed by a rapid decline in both NH sub(4) super(+)-N and nitrification with increasing time since inundation (>11 days post inundation). Nitrification rates were also highest following the flood in Phalaris sites, but rates did not depend on elevation, likely because of the lack of elevational differences in soil properties. Our results generally support the flood-pulse concept of river-floodplain connectivity, with the highest nitrification rates found in areas and during times immediately following inundation. Furthermore, restoration of forest cover in areas invaded by Phalaris appears likely to restore flood-pulse effects on abiotic soil properties and nitrification dynamics.

Fine-scale physiological or phenological adaptations that direct demographic processes may drive intraspecific variability when baseline environmental conditions change. Landscape genomics characterize adaptive differentiation by identifying environmental drivers of adaptive genetic variability and mapping the associated landscape patterns. We applied such an approach to Sphaeralcea ambigua, an important restoration plant in the arid southwestern United States, by analyzing variation at 153 amplified fragment length polymorphism loci in the context of environmental gradients separating 47 Mojave Desert populations. We identified 37 potentially adaptive loci through a combination of genome scan approaches. We then used a generalized dissimilarity model (GDM) to relate variability in potentially adaptive loci with spatial gradients in temperature, precipitation, and topography. We identified non-linear thresholds in loci frequencies driven by summer maximum temperature and water stress, along with continuous variation corresponding to temperature seasonality. Two GDM-based approaches for mapping predicted patterns of local adaptation are compared. Additionally, we assess uncertainty in spatial interpolations through a novel spatial bootstrapping approach. Our study presents robust, accessible methods for deriving spatially-explicit models of adaptive genetic variability in non-model species that will inform climate change modelling and ecological restoration.

These changes in precipitation patterns may have profound ecosystem effects, depending on the sensitivities of the dominant plant functional types (PFTs). Here we present the responses of four Colorado Plateau PFTs to an experimentally imposed, 4-year, press-drought during which a natural pulse-drought occurred. Our objectives were to (1) identify the drought sensitivities of the PFTs, (2) assess the additive effects of the press- and pulse-drought, and (3) examine the interactive effects of soils and drought. Our results revealed that the C sub(3) grasses were the most sensitive PFT to drought, the C sub(3) shrubs were the most resistant, and the C sub(4) grasses and shrubs had intermediate drought sensitivities. Although we expected the C sub(3) grasses would have the greatest response to drought, the higher resistance of C sub(3) shrubs relative to the C sub(4) shrubs was contrary to our predictions based on the higher water use efficiency of C sub(4) photosynthesis. Also, the additive effects of press- and pulse-droughts caused high morality in C sub(3) grasses, which has large ecological and economic ramifications for this region. Furthermore, despite predictions based on the inverse texture hypothesis, we observed no interactive effects of soils with the drought treatment on cover or mortality. These results suggest that plant responses to droughts in drylands may differ from expectations and have large ecological effects if press- and pulse-droughts push species beyond physiological and mortality thresholds.

Cryptic and wide-ranging behaviours of bats make them difficult to survey, and population estimation is often intractable. We advance a model-based framework for making spatially explicit predictions about summertime distributions of bats from capture and acoustic surveys. Motivated by species-energy and life-history theory, our models describe hypotheses about spatio-temporal variation in bat distributions along environmental gradients and life-history attributes, providing a statistical basis for conservation decision-making. Location Oregon and Washington, USA. Methods We developed Bayesian hierarchical models for 14 bat species from an 8-year monitoring dataset across a ~430,000 km super(2) study area. Models accounted for imperfect detection and were temporally dynamic. We mapped predicted occurrence probabilities and prediction uncertainties as baselines for assessing future declines. Results Forest cover, snag abundance and cliffs were important predictors for most species. Species occurrence patterns varied along elevation and precipitation gradients, suggesting a potential hump-shaped diversity-productivity relationship. Annual turnover in occurrence was generally low, and occurrence probabilities were stable among most species. We found modest evidence that turnover covaried with the relative riskiness of bat roosting and migration. The fringed myotis (Myotis thysanodes), canyon bat (Parastrellus hesperus) and pallid bat (Antrozous pallidus) were rare; fringed myotis occurrence probabilities declined over the study period. We simulated anticipated declines to demonstrate that mapped occurrence probabilities, updated over time, provide an intuitive way to assess bat conservation status for a broad audience. Main conclusions Landscape keystone structures associated with roosting habitat emerged as regionally important predictors of bat distributions. The challenges of bat monitoring have constrained previous species distribution modelling efforts to temporally static presence-only approaches. Our approach extends to broader spatial and temporal scales than has been possible in the past for bats, making a substantial increase in capacity for bat conservation.

Pinon pines have been especially affected by these events, and drought severity is predicted to increase in this region in the future. Based on research that suggests winter climate may influence growing season productivity in semiarid ecosystems, we evaluated the potential for small changes in average winter climate to affect spring growing season conditions in pinon-juniper woodlands, New Mexico, USA. We developed a low-dimensional ecohydrological model of pinon-juniper woodland ecosystems on moderate slopes (5%) and on steep slopes (25%) and simulated the responses of ecosystem water availability, surface conditions, and water and carbon flux dynamics to a climate change scenario of increased temperature and decreased winter precipitation. The climate change scenario reduced average winter snowcover, decreased surface albedo, increased net radiation, and altered the timing of spring evaporation (E) towards earlier dates. Moderate slope pinon and juniper trees experienced small reductions in transpiration (Tr) and carbon assimilation (A), and those on steep slopes experienced small but relatively larger reductions in Tr and A, as well as higher increases in soil moisture ( theta ) variance and E variance. As a result of climate change, the peak of spring Tr occurred on average 6 days earlier on moderate slopes and 10 days earlier on steep slopes, the timing of A shifted towards earlier March dates, and A was reduced during April and May. Steep slope pinon pines experienced greater proportional reductions in Tr and A than junipers. Our results suggests that winter climate change will promote an earlier growing season in pinon-juniper woodlands, will increase daily variance in theta and E during spring, and will produce slight reductions in A in woodlands with steep slopes and a large proportion of pinon pines. In a more arid future climate, a shift towards lower soil moisture availability and carbon assimilation in April and May may intensify the effects of early summer drought events for pinon-juniper woodlands, thus exacerbating the impacts of larger changes in climate dynamics.

AN - 1731783731; 26378165 AB - The white sucker Catostomus commersonii is a freshwater teleost often utilized as a resident sentinel. Here, we sequenced the full genome of a hepatitis B-like virus that infects white suckers from the Great Lakes Region of the United States. Dideoxy sequencing confirmed that the white sucker hepatitis B virus (WSHBV) has a circular genome (3,542 bp) with the prototypical codon organization of hepadnaviruses. Electron microscopy demonstrated that complete virions of approximately 40 nm were present in the plasma of infected fish. Compared to avi- and orthohepadnaviruses, sequence conservation of the core, polymerase, and surface proteins was low and ranged from 16 to 27% at the amino acid level. An X protein homologue common to the orthohepadnaviruses was not present. The WSHBV genome included an atypical, presumptively noncoding region absent in previously described hepadnaviruses. Phylogenetic analyses confirmed WSHBV as distinct from previously documented hepadnaviruses. The level of divergence in protein sequences between WSHBV and other hepadnaviruses and the identification of an HBV-like sequence in an African cichlid provide evidence that a novel genus of the family Hepadnaviridae may need to be established that includes these hepatitis B-like viruses in fishes. Viral transcription was observed in 9.5% (16 of 169) of white suckers evaluated. The prevalence of hepatic tumors in these fish was 4.9%, and only 2.4% of fish were positive for both virus and hepatic tumors. These results are not sufficient to draw inferences regarding the association of WSHBV and carcinogenesis in white sucker. We report the first full-length genome of a hepadnavirus from fishes. Phylogenetic analysis of this genome indicates divergence from genomes of previously described hepadnaviruses from mammalian and avian hosts and supports the creation of a novel genus. The discovery of this novel virus may better our understanding of the evolutionary history of hepatitis B-like viruses of other hosts. In fishes, knowledge of this virus may provide insight regarding possible risk factors associated with hepatic neoplasia in the white sucker. This may also offer another model system for mechanistic research. Copyright © 2015 Hahn et al.

A holding time comparison for total coliforms, Escherichia coli, and enterococci was done by analyzing samples within 8 h using presence/absence methods and within 18-30 h using quantitative methods. The data indicate that results obtained within 18-30 h were not significantly different from those obtained within 8 h for total coliforms and enterococci, by Colilert registered and Enterolert registered methods (IDEXX Laboratories Inc., Westbrook, ME), respectively. Quantitative laboratory methods for samples analyzed within 18-30 h showed a statistically significant higher detection frequency when compared to presence/absence methods done within 8 h for the following methods, E. coli by Colilert and enterococci by membrane filtration on mEI agar. Additionally, a comparison of methods for the enumeration of enterococci was done. Using non-parametric statistical analyses, results from the two methods were statistically different. In this study, the membrane filtration method on mEI agar was more sensitive, resulted in more detections of enterococci, and results were easier to interpret than with the quantitative Enterolert method. The quantitative Enterolert method produced varying levels of fluorescence, which required additional verification steps to eliminate false-positive results. It may be more advantageous to analyze untreated groundwater for enterococci using the membrane filtration method on mEI agar.

However, our understanding of the factors that drive threshold dynamics, and when and how rapidly thresholds will be crossed is currently limited in many systems. In spite of these limitations, there are approaches available to practitioners today-including ecosystem monitoring, statistical methods to identify thresholds and indicators, and threshold-based adaptive management-that can be used to help avoid reaching ecological thresholds or restore systems that have crossed them. We briefly review the current state of knowledge and then use real-world examples to demonstrate how resource managers can use available approaches to avoid crossing ecological thresholds. We also highlight new tools and indicators being developed that have the potential to enhance our ability to detect change, predict when a system is approaching an ecological threshold, or restore systems that have already crossed a tipping point.

Quality assurance of the turbulence measurements was verified by the close comparison between results of time-averaged quantities calculated with the measurements and published semiempirical equations for decelerating flow over gravel beds. The presence of macroturbulence within the flow is verified using turbulence decomposition, spectral analysis, and the distribution of time-averaged quantities. The vertical expansion velocity provided 40% of the turbulent energy production in the vertical suggesting that the expansion velocity interacts with macroturbulence in the outer region to generate and redistribute energy. Spectral analyses show that net turbulent energy is primarily lost through the decelerating flow at 1 to 10 Hz frequencies associated with the bursting process and dissipative scales while the primary streamwise energy reduction is less pronounced in the macroturbulence range. Vertical and transverse turbulent energy within the macroturbulence range actually becomes more energetic as the flow decelerates. Macroturbulence makes up nearly equal 50% of the total streamwise turbulent kinetic energy, and the loss of macroturbulence energy through the decelerating flow lags well behind that of the decreasing intensity of bursting as identified with quadrant analysis. Taken together, the results of this study suggest that macroturbulence is a defining feature of the fully rough expanding flow that sustains itself from bed-derived bursting as well as flow nonuniformities.

This paper enhances the WRTDS method through the introduction of the WRTDS Bootstrap Test (WBT), an extension of WRTDS that quantifies the uncertainty in WRTDS-estimates of water quality trends and offers various ways to visualize and communicate these uncertainties. Monte Carlo experiments are applied to estimate the Type I error probabilities for this method. WBT is compared to other water-quality trend-testing methods appropriate for data sets of one to three decades in length with sampling frequencies of 6-24 observations per year. The software to conduct the test is in the EGRETci R-package.

Chloride concentrations in some wells increased during that time and exceeded the US Environmental Protection Agency's secondary maximum contaminant level of 250 mg/L, resulting in removal of some wells from service. Sources of high-chloride water include irrigation return in 16 % of sampled wells and water from delta sediments and deeper groundwater in 50 % of sampled wells. Chloride concentrations resulting from irrigation return commonly did not exceed 100 mg/L, although nitrate concentrations were as high as 25 mg/L as nitrogen. Chloride concentrations ranged from less than 100-2,050 mg/L in wells affected by water from delta sediments and deeper groundwater. Sequential electromagnetic logs show movement of high-chloride water from delta sediments to pumping wells through permeable interconnected aquifer layers. delta D and delta super(18)O data show most groundwater originated as recharge along the front of the Sierra Nevada, but tritium and carbon-14 data suggest recharge rates in this area are low and have decreased over recent geologic time. Managed aquifer recharge at two sites show differences in water-level responses to recharge and in the physical movement of recharged water with depth related to subsurface geology. Well-bore flow logs also show rapid movement of water from recharge sites through permeable interconnected aquifer layers to pumping wells.Original Abstract: Du fait de pompages excessifs dans la zone de recharge, les niveaux piezometriques d'aquiferes alluviaux du sous-bassin de l'est de San Joaquin, 130 km a l'est de San Francisco (Californie, USA), ont baisse en dessous du niveau de la mer au debut des annees 1950 et se maintiennent depuis a ces bas niveaux. La concentration en chlorure dans quelques forages a augmente lors de cette periode jusqu'a depasser la valeur maximum de 250 mg/L fixee par l'Agence pour la Protection Environnementale Americaine (US EPA), entrainant l'arret de l'utilisation de certains forages. L'origine de ces eaux enrichies en chlorures comprend la reinfiltration des eaux d'irrigation pour 16 % des forages echantillonnees et les eaux des sediments du delta et les eaux souterraines plus profondes pour 50 % des forages echantillonnes. Les concentrations en chlorures resultant de la reinfiltration des eaux d'irrigation ne depassent generalement pas 100 mg/L alors que les concentrations en nitrates sont elevees atteignant 25 mg/L d'azote. Les concentrations en chlorure sont comprises entre moins de 100 a 2,050 mg/L dans les forages influences par les eaux des sediments du delta et les eaux souterraines plus profondes. Des profils electromagnetiques sequentiels montrent le mouvement des eaux riches en chlorures des sediments du delta vers les forages pompes au travers des niveaux permeables interconnectes. Les donnees de delta D et delta super(18)O montrent que la plupart des eaux souterraines proviennent de la recharge le long du front de la Sierra Nevada. Toutefois les donnees de tritium et carbone-14 suggerent que le taux de recharge dans ce secteur est faible et a diminue avec les temps geologiques. La gestion des systemes de recharge des aquiferes sur deux sites montre des differences dans la reponse du changement de niveau avec la recharge et dans le mouvement physique de l'eau rechargee avec la profondeur en relation avec la geologie de sub-surface. Les profils de flux des forages montrent un mouvement rapide des eaux depuis les sites de recharge au travers des niveaux aquiferes permeables interconnectes vers les forages pompes.

Fluid-injection tests were conducted on intervals of boreholes isolating closely spaced fractures. Single-hole tests were conducted by pumping in open boreholes for approximately 30 min, and an interference test was conducted by pumping a single borehole over 3 days while monitoring nearby boreholes. An estimate of the hydraulic conductivity of the rock over hundreds of meters was inferred from simulating groundwater inflow into a kilometer-long section of a Washington Metropolitan Area Transit Authority tunnel in the study area, and a groundwater modeling investigation over the Rock Creek watershed provided an estimate of the hydraulic conductivity over kilometers. The majority of groundwater flow is confined to relatively few fractures at a given location. Boreholes installed to depths of approximately 50 m have one or two highly transmissive fractures; the transmissivity of the remaining fractures ranges over five orders of magnitude. Estimates of hydraulic conductivity over increasingly larger rock volumes varied by less than half an order of magnitude. While many investigations point to increasing hydraulic conductivity as a function of the measurement scale, a comparison with selected investigations shows that the effective hydraulic conductivity estimated over larger volumes of rock can either increase, decrease, or remain stable as a function of the measurement scale. Caution needs to be exhibited in characterizing effective hydraulic properties in fractured rock for the purposes of groundwater management.Original Abstract: Une comparaison de la conductivite hydraulique sur des volumes de roche cristalline en augmentation croissante a ete realisee dans la region physiographique du Piedmont pres de Bethesda, Maryland, USA. Des essais d'injection de fluide ont ete conduits sur des intervalles de forages isolant des fractures tres proches les unes des autres. Des essais en puits unique ont ete realises par pompage au sein de forages ouverts durant approximativement 30 minutes et un essai d'interferences a ete conduit par pompage dans un forage unique, durant trois jours, avec suivi des forages voisins. Une evaluation de la conductivite hydraulique de la roche a ete deduite sur des centaines de metres en simulant les entrees d'eau souterraine dans une section d'un kilometre de long du tunnel de l'autorite de transit de la region metropolitaine de Washington et un travail de modelisation des eaux souterraines sur le bassin versant du Creek Rock a fourni une estimation de la conductivite hydrauliques sur des kilometres. En un lieu donne, la majorite de l'ecoulement d'eau souterraine est confinee au sein de relativement peu de fractures. Des forages atteignant des profondeurs d'environ 50 m recoupent une ou deux fractures tres transmissives; la transmissivite des autres fractures couvre une gamme de cinq ordres de grandeur. Les estimations de la conductivite hydraulique sur des volumes de roche en augmentation croissante varient sur moins de la moitie d'un ordre de grandeur. Tandis que de nombreux travaux soulignent l'augmentation de la conductivite hydraulique en fonction de l'echelle de mesure, une comparaison avec des travaux selectionnes montre que la conductivite hydraulique equivalente estimee sur de gros volumes de roche peut soit augmenter, decroitre ou rester stable en fonction de l'echelle de mesure. Des precautions doivent etre prises lors de la caracterisation des proprietes de conductivite hydraulique equivalente des roches fracturees avec des objectifs de gestion des eaux souterraines.

To better understand the various processes that cause transformation, a data aggregation, validation, and attribution approach was developed and applied to an analysis of the Southeastern Coastal Plains (SECP). The approach integrates information from available national land-use, natural disturbance, and land-cover data to efficiently assess spatially-specific changes and causes. Between 2001 and 2006, the processes of change affected 7.8 % of the SECP but varied across small-scale ecoregions. Processes were placed into a simple conceptual framework to explicitly identify the type and direction of change based on three general characteristics: replacement, recurrence, and recovery. Replacement processes, whereby a land use or cover is supplanted by a new land use, including urbanization and agricultural expansion, accounted for approximately 15 % of the extent of change. Recurrent processes that contribute to cyclical changes in land cover, including forest harvest/replanting and fire, accounted for 83 %. Most forest cover changes were recurrent, while the extents of recurrent silviculture and forest replacement processes such as urbanization far exceeded forest recovery processes. The total extent of landscape recovery, from prior land use to natural or semi-natural vegetation cover, accounted for less than 3 % of change. In a region of complex change, increases in transitory grassland and shrubland covers were caused by large-scale intensive plantation silviculture and small-scale activities including mining reclamation. Explicit identification of the process types and dynamics presented here may improve the understanding of land-cover change and landscape trajectory.

AN - 1722924014; 26242803 AB - Pb and Cd contents in 13 plantation tree species (leaf and branch components), soil, water (groundwater and river water) at a young (3-5 year-old) seashore afforestation stand were investigated in Nansha district, Guangzhou city in southern China. The results showed that (1) soil, rather than water or trees, had the highest content of both Pb (averagely 48.79 mg/kg) and Cd (0.50 mg/kg), demonstrating that soil might function as a major reservoir for extraneously derived heavy metals; (2) Pb content was higher in branches than in leaves, but Cd content appeared similar in both components, implying possibly different accumulation mechanisms in trees; (3) Pb and Cd appeared to accumulate differently among some tree taxa, whereas almost no significant difference was detected between introduced and indigenous species. The study indicated that trees were potentially useful to remediate sites contaminated with Pb and Cd in the urbanized areas.

AN - 1708165338; 26102057 AB - Animal feeding operations (AFOs) have been implicated as potentially major sources of estrogenic contaminants into the aquatic environment due to the relatively minimal treatment of waste and potential mobilization and transport of waste components from spray fields. In this study a Bayesian network (BN) model was developed to inform management decisions and better predict the transport and fate of natural steroidal estrogens from these sites. The developed BN model integrates processes of surface runoff and sediment loss with the modified universal soil loss equation (MUSLE) and the soil conservation service curve number (SCS-CN) runoff model. What-if scenario simulations of lagoon slurry wastes to the spray fields were conducted for the most abundant natural estrogen estrone (E1) observed in the system. It was found that E1 attenuated significantly after 2 months following waste slurry application in both spring and summer seasons, with the overall attenuation rate predicted to be higher in the summer compared to the spring. Using simulations of rainfall events in conjunction with waste slurry application rates, it was predicted that the magnitude of E1 runoff loss is significantly higher in the spring as compared to the summer months, primarily due to spray field crop management plans. Our what-if scenario analyses suggest that planting Bermuda grass in the spray fields is likely to reduce runoff losses of natural estrogens near the water bodies and ecosystems, as compared to planting of soybeans.

PQ0003988036 AB - Golovin, Alaska is situated on an Arctic spit subject to storm surge-induced geohazards from extratropical Pacific storms that regularly pass through the Bering Sea during fall storm seasons. Although generalized reports by the U.S. Army Corps of Engineers and the Government Accountability Office have found Golovin to be a priority action community for flooding and erosion, the localized assessment described here shows the shoreline to be dynamically stable with the highest potential for flooding on the lagoon side of the spit which is subjected to lower wave energy compared to the open ocean side. By incorporating long- and short-term morphologic measurements with nearshore numerical and empirically parameterized modeling, flooding and erosion are projected here for a range of 5- to100-year storm return intervals. Flooding at Golovin is expected to be confined to the low wave-energy side of the spit during 5- and 10-year (recurrence interval) storms, with the 25-year storm identified as the most likely threshold event for overwash and flooding from the offshore direction. 50- to 100-year events are expected to overwash and flood from both sides of the spit. Golovin is less at risk from erosion than previous reports suggest which makes improved localized coastal geohazard assessments necessary for hazard mitigation design and management strategies, not only for Golovin, but other communities along the coast of Alaska that face similar geohazards.

Jurisdictional determinations are required for many intermittent and ephemeral streams, where significant nexus with downstream traditional navigable waters (TNWs) must be evaluated. Three biophysical metrics (a streamflow metric, distance from the stream to the TNW, and slope between the stream and the TNW) for 239 streams in the watershed were used to develop three indices. These were then combined to develop the HCI, which is a compound, additive index. There was a large range of HCI values for ephemeral streams, which all require a significant nexus evaluation to determine jurisdiction. Statistical analysis of HCI values across stream duration and order classes showed that mean values differed significantly among classes. The flow index component constituted the greatest proportion of the HCI for perennial streams, was sensitive to the flow metrics used, and was greatest for high flows. Although ephemeral streams are only connected to the TNW less than 3 months of the year, the cumulative average annual flow contribution of ephemeral first-order streams can be 5 % of the total to the TNW, and their flow contribution is larger during high flows. Some ephemeral streams with high HCI values are farthest from the TNW but contribute the greatest flow out of all ephemeral reaches, and may have significant nexus with the river. The study shows that the HCI can be useful for initial evaluation of connectivity, significant nexus, and jurisdiction of headwaters at the watershed scale.

Alaska and Hawaii (HI) remain the only U.S. states in which transmission of WNV has not been detected. Dead bird surveillance has played an important role in the detection of the virus geographically, as well as temporally. In North America, corvids have played a major role in WNV surveillance; however, the only corvid in HI is the endangered Hawaiian crow that exists only in captivity, thus precluding the use of this species for WNV surveillance in HI. To evaluate the suitability of alternate avian species for WNV surveillance, we experimentally challenged seven abundant non-native bird species present in HI with WNV and compared mortality, viremia, oral shedding of virus, and seroconversion. For detection of WNV in oral swabs, we compared viral culture, reverse-transcriptase polymerase chain reaction, and the RAMP test. For detection of antibodies to WNV, we compared an indirect and a competitive enzyme-linked immunoassay. We found four species (house sparrow, house finch, Japanese white-eye, and Java sparrow) that may be useful in dead bird surveillance for WNV; while common myna, zebra dove, and spotted dove survived infection and may be useful in serosurveillance.

Although sedimentary and geomorphic responses to sediment pulses are a fundamental part of landscape evolution, few opportunities exist to quantify those processes over field scales. We investigated the downstream effects of sediment released during the largest dam removal in history, on the Elwha River, Washington, USA, by measuring changes in riverbed elevation and topography, bed sediment grain size, and channel planform as two dams were removed in stages over two years. As 10.5 million t (7.1 million m (super 3) ) of sediment was released from two former reservoirs, downstream dispersion of a sediment wave caused widespread bed aggradation of approximately 1 m (greater where pools filled), changed the river from pool-riffle to braided morphology, and decreased the slope of the lowermost river. The newly deposited sediment, which was finer than most of the pre-dam-removal bed, formed new bars (largely pebble, granule, and sand material), prompting aggradational channel avulsion that increased the channel braiding index by almost 50%. As a result of mainstem bed aggradation, floodplain channels received flow and accumulated new sediment even during low to moderate flow conditions. The river system showed a two- to tenfold greater geomorphic response to dam removal (in terms of bed elevation change magnitude) than it had to a 40-year flood event four years before dam removal. Two years after dam removal began, as the river had started to incise through deposits of the initial sediment wave, approximately 1.2 million t of new sediment ( nearly equal 10% of the amount released from the two reservoirs) was stored along 18 river km of the mainstem channel and 25 km of floodplain channels. The Elwha River thus was able to transport most of the released sediment to the river mouth. The geomorphic alterations and changing bed sediment grain size along the Elwha River have important ecological implications, affecting aquatic habitat structure, benthic fauna, salmonid fish spawning and rearing potential, and riparian vegetation. The response of the river to dam removal represents a unique opportunity to observe and quantify fundamental geomorphic processes associated with a massive sediment influx, and also provides important lessons for future river-restoration endeavors.

Many case studies exist for small dam removals with a few years of sediment storage or dam breaches triggering instantaneous large sediment releases. However, quantitative information for a controlled drawdown initiating erosion of a large sediment deposit is rare. We investigate reservoir sediment response to the phased and concurrent drawdown of two reservoirs on the Elwha River, Washington, USA, during the largest dam removal in history by measuring changes in reservoir topography and channel morphology as a function of base-level lowering, river discharge, and cohesion. After two years, the Elwha Dam was completely removed, and three-quarters of Glines Canyon Dam were removed. Reservoir drawdown increments of 3 to 5 m were sufficient to initiate channel degradation and delta progradation across the width of the receding reservoir, redistributing decades of accumulated delta sediment throughout the reservoir while the lake still remained. The first year of dam removal resulted in up to 5 m of incision through the Lake Aldwell delta down to the predam surface and in just over 20 m of incision through the Lake Mills delta. In contrast, delta progradation resulted in a few meters of deposition in Lake Aldwell and 2 to 10 m in Lake Mills on top of prodelta and lakebed deposits. In coarse, noncohesive sediment, a braided channel developed and widened up to tenfold across the entire width of the reservoir. The most extensive lateral erosion occurred in noncohesive deposits during multiweek hold periods coinciding with flows greater than the mean annual flow, but less than a 2-year flood peak. Channel widening in more cohesive fine sediments of the prodelta and lakebed was less than half of that in the coarse, noncohesive delta sediments. Dam removal resulted in the erosion and downstream release of 23% of the sediment in Lake Aldwell (1.12 + or - 0.07 million m (super 3) ) and 37% of the sediment in Lake Mills (5.95 + or - 0.12 million m (super 3) ), representing nearly four decades of sediment supply from the upstream watershed within a two-year time frame. A significant portion of the reservoir sediment is expected to remain as sediment terraces within the reservoir landscape, but additional erosion is expected after the remainder of the Glines Canyon Dam is removed and during future floods until the river reaches quasi-equilibrium. After phased dam removal, the reservoir landscape consists of a series of sediment terraces of varying heights composed of prograded coarse sediment overlying fine lakebed deposits. The predam surface is exposed along the river corridor, and abundant 1- to 3-m stumps from pre-removal forests create unique morphology where the river interacts with the predam landscape.

Starting September 2011, two nearly century-old dams that collectively contained 21 + or - 3 million m (super 3) of sediment were removed over the course of three years with a top-down deconstruction strategy designed to meter the release of a portion of the dam-trapped sediment. Gauging with sediment-surrogate technologies during the first two years downstream from the project measured 8,200,000 + or - 3,400,000 tonnes of transported sediment, with 1,100,000 and 7,100,000 t moving in years 1 and 2, respectively, representing 3 and 20 times the Elwha River annual sediment load of 340,000 + or - 80,000 t/y. During the study period, the discharge in the Elwha River was greater than normal (107% in year 1 and 108% in year 2); however, the magnitudes of the peak-flow events during the study period were relatively benign with the largest discharge of 292 m (super 3) /s (73% of the 2-year annual peak-flow event) early in the project when both extant reservoirs still retained sediment. Despite the muted peak flows, sediment transport was large, with measured suspended-sediment concentrations during the study period ranging from 44 to 16,300 mg/L and gauged bedload transport as large as 24,700 t/d. Five distinct sediment-release periods were identified when sediment loads were notably increased (when lateral erosion in the former reservoirs was active) or reduced (when reservoir retention or seasonal low flows and cessation of lateral erosion reduced sediment transport). Total suspended-sediment load was 930,000 t in year 1 and 5,400,000 t in year 2. Of the total 6,300,000 + or - 3,200,000 t of suspended-sediment load, 3,400,000 t consisted of silt and clay and 2,900,000 t was sand. Gauged bedload on the lower Elwha River in year 2 of the project was 450,000 + or - 360,000 t. Bedload was not quantified in year 1, but qualitative observations using bedload-surrogate instruments indicated detectable bedload starting just after full removal of the downstream dam. Using comparative studies from other sediment-laden rivers, the total ungauged fraction of < 2-mm bedload was estimated to be on the order of 1.5 Mt. Abstract Copyright (2015) Elsevier, B.V.

The phased removal of two large dams on the Elwha River, Washington, exposed 21 + or - 3 million m (super 3) , or approximately 30 million tonnes (t), of sediment that had been deposited in the two former reservoirs, allowing a comprehensive investigation of watershed and coastal responses to a substantial increase in sediment supply. Here we provide a source-to-sink sediment budget of this sediment release during the first two years of the project (September 2011-September 2013) and synthesize the geomorphic changes that occurred to downstream fluvial and coastal landforms. Owing to the phased removal of each dam, the release of sediment to the river was a function of the amount of dam structure removed, the progradation of reservoir delta sediments, exposure of more cohesive lakebed sediment, and the hydrologic conditions of the river. The greatest downstream geomorphic effects were observed after water bodies of both reservoirs were fully drained and fine (silt and clay) and coarse (sand and gravel) sediments were spilling past the former dam sites. After both dams were spilling fine and coarse sediments, river suspended-sediment concentrations were commonly several thousand mg/L with approximately 50% sand during moderate and high river flow. At the same time, a sand and gravel sediment wave dispersed down the river channel, filling channel pools and floodplain channels, aggrading much of the river channel by approximately 1 m, reducing river channel sediment grain sizes by approximately 16-fold, and depositing approximately 2.2 million m (super 3) of sand and gravel on the seafloor offshore of the river mouth. The total sediment budget during the first two years revealed that the vast majority ( approximately 90%) of the sediment released from the former reservoirs to the river passed through the fluvial system and was discharged to the coastal waters, where slightly less than half of the sediment was deposited in the river-mouth delta. Although most of the measured fluvial and coastal deposition was sand-sized and coarser (> 0.063 mm), significant mud deposition was observed in and around the mainstem river channel and on the seafloor. Woody debris, ranging from millimeter-size particles to old-growth trees and stumps, was also introduced to fluvial and coastal landforms during the dam removals. At the end of our two-year study, Elwha Dam was completely removed, Glines Canyon Dam had been 75% removed (full removal was completed 2014), and approximately 65% of the combined reservoir sediment masses-including approximately 8 Mt of fine-grained and approximately 12 Mt of coarse-grained sediment-remained within the former reservoirs. Reservoir sediment will continue to be released to the Elwha River following our two-year study owing to a approximately 16 m base level drop during the final removal of Glines Canyon Dam and to erosion from floods with larger magnitudes than occurred during our study. Comparisons with a geomorphic synthesis of small dam removals suggest that the rate of sediment erosion as a percent of storage was greater in the Elwha River during the first two years of the project than in the other systems. Comparisons with other Pacific Northwest dam removals suggest that these steep, high-energy rivers have enough stream power to export volumes of sediment deposited over several decades in only months to a few years. These results should assist with predicting and characterizing landscape responses to future dam removals and other perturbations to fluvial and coastal sediment budgets.

In a previous study, a synthetic sex pheromone component 7 alpha ,12 alpha , 24-trihydroxy-5 alpha -cholan-3-one 24-sulfate (3kPZS) was applied to sea lamprey traps in eight streams at a final in-stream concentration of 10 super(-12) M. Application of 3kPZS increased sea lamprey catch, but where and when 3kPZS had the greatest impact was not determined. Here, by applying 3kPZS to additional streams, we determined that overall increases in yearly exploitation rate (proportion of sea lampreys that were marked, released, and subsequently recaptured) were highest (20-40 %) in wide streams (~40 m) with low adult sea lamprey abundance (<1000). Wide streams with low adult abundance may be representative of low-attraction systems for adult sea lamprey and, in the absence of other attractants (larval odor, sex pheromone), sea lamprey may have been more responsive to a partial sex pheromone blend emitted from traps. Furthermore, we found that the largest and most consistent responses to 3kPZS were during nights early in the trapping season, when water temperatures were increasing. This may have occurred because, during periods of increasing water temperatures, sea lamprey become more active and males at large may not have begun to release sex pheromone. In general, our results are consistent with those for pheromones of invertebrates, which are most effective when pest density is low and when pheromone competition is low.

Often, only a single soil unit is employed, and soil-hydraulic properties are assigned based on textural classification, without evaluating the potential impact of these simplifications. This study uses a distributed physics-based model to assess the influence of soil horizons and structure on effective parameterization. This paper tests the viability of two established and widely used hydrogeologic methods for simulating runoff and variably saturated flow through layered soils: (1) accounting for vertical heterogeneity by combining hydrostratigraphic units with contrasting hydraulic properties into homogeneous, anisotropic units and (2) use of established pedotransfer functions based on soil texture alone to estimate water retention and conductivity, without accounting for the influence of pedon structures and hysteresis. The viability of this latter method for capturing the seasonal transition from runoff-dominated to evapotranspiration-dominated regimes is also tested here. For cases tested here, event-based simulations using simplified vertical heterogeneity did not capture the state-dependent anisotropy and complex combinations of runoff generation mechanisms resulting from permeability contrasts in layered hillslopes with complex topography. Continuous simulations using pedotransfer functions that do not account for the influence of soil structure and hysteresis generally over-predicted runoff, leading to propagation of substantial water balance errors. Analysis suggests that identifying a dominant hydropedological unit provides the most acceptable simplification of subsurface layering and that modified pedotransfer functions with steeper soil-water retention curves might adequately capture the influence of soil structure and hysteresis on hydrologic response in headwater catchments.

The giant gartersnake (Thamnophis gigas) is a state and federally threatened species that historically occurred in the wetland habitats of California's Great Central Valley. Despite the loss of 93 % of historic wetlands throughout the Central Valley, giant gartersnakes continue to persist in relatively small, isolated patches of highly modified agricultural wetlands. Gathering information regarding genetic diversity and effective population size represents an essential component for conservation management programs aimed at this species. Previous mitochondrial sequence studies have revealed historical patterns of differentiation, yet little is known about contemporary population structure and diversity. On the basis of 15 microsatellite loci, we estimate population structure and compare indices of genetic diversity among populations spanning seven drainage basins within the Central Valley. We sought to understand how habitat loss may have affected genetic differentiation, genetic diversity and effective population size, and what these patterns suggest in terms of management and restoration actions. We recovered five genetic clusters that were consistent with regional drainage basins, although three northern basins within the Sacramento Valley formed a single genetic cluster. Our results show that northern drainage basin populations have higher connectivity than among central and southern basins populations, and that greater differentiation exists among the more geographically isolated populations in the central and southern portion of the species' range. Genetic diversity measures among basins were significantly different, and were generally lower in southern basin populations. Levels of inbreeding and evidence of population bottlenecks were detected in about half the populations we sampled, and effective population size estimates were well below recommended minimum thresholds to avoid inbreeding. Efforts focused on maintaining and enhancing existing wetlands to facilitate dispersal between basins and increase local effective population sizes may be critical for these otherwise isolated populations.

AN - 1705734611; 26114899 AB - The last large-scale ecotoxicological study of ospreys (Pandion haliaetus) in Chesapeake Bay was conducted in 2000-2001 and focused on U.S. EPA-designated Regions of Concern (ROCs; Baltimore Harbor/Patapsco, Anacostia/middle Potomac, and Elizabeth Rivers). In 2011-2012, ROCs were re-evaluated to determine spatial and temporal trends in productivity and contaminants. Concentrations of p,p'-DDE were low in eggs and below the threshold associated with eggshell thinning. Eggs from the Anacostia/middle Potomac Rivers had lower total PCB concentrations in 2011 than in 2000; however, concentrations remained unchanged in Baltimore Harbor. Polybrominated diphenyl ether flame retardants declined by 40%, and five alternative brominated flame retardants were detected at low levels. Osprey productivity was adequate to sustain local populations, and there was no relation between productivity and halogenated contaminants. Our findings document continued recovery of the osprey population, declining levels of many persistent halogenated compounds, and modest evidence of genetic damage in nestlings from industrialized regions.

Quantitative models mathematically reflect scientific hypotheses about how a system functions. In Delaware Bay, mid-Atlantic Coast, USA, to more effectively manage horseshoe crab (Limulus polyphemus) harvests and protect Red Knot (Calidris canutus rufa) populations, models are used to compare harvest actions and predict the impacts on crab and knot populations. Management has been chiefly driven by the core hypothesis that horseshoe crab egg abundance governs the survival and reproduction of migrating Red Knots that stopover in the Bay during spring migration. However, recently, hypotheses proposing that knot dynamics are governed by cyclical lemming dynamics garnered some support in data analyses. In this paper, I present alternative models of Red Knot population dynamics to reflect alternative hypotheses. Using 2 models with different lemming population cycle lengths and 2 models with different horseshoe crab effects, I project the knot population into the future under environmental stochasticity and parametric uncertainty with each model. I then compare each model's predictions to 10 yr of population monitoring from Delaware Bay. Using Bayes' theorem and model weight updating, models can accrue weight or support for one or another hypothesis of population dynamics. With 4 models of Red Knot population dynamics and only 10 yr of data, no hypothesis clearly predicted population count data better than another. The collapsed lemming cycle model performed best, accruing ~35% of the model weight, followed closely by the horseshoe crab egg abundance model, which accrued ~30% of the weight. The models that predicted no decline or stable populations (i.e. the 4-yr lemming cycle model and the weak horseshoe crab effect model) were the most weakly supported.

Here, we report field and laboratory evidence that suggest LACV may be using Culex mosquitoes as additional vectors in this region. This bunyavirus was detected by reverse-transcriptase polymerase chain reaction in two pools of Culex mosquitoes in southwestern Virginia and in six pools in West Virginia. To assess vector competence, we offered LACV blood meals to field-collected Culex restuans Theobald, Cx. pipiens L., and Aedes triseriatus(Say). Both Culex species were susceptible to infection. LACV-positive salivary expectorate, indicative of the ability to transmit, was detected in a small proportion of Cx. restuans(9%) and Cx. pipiens(4%) compared with Ae. triseriatus(40%). In a companion study of Cx. restuans only, we found that adults derived from nutritionally stressed larvae were significantly more likely to disseminate and transmit LACV. Our results indicate a potential role of Culex spp. in LACV dynamics that should be explored further in endemic areas.

Because humans have affected Mediterranean ecosystems for millennia, it is unclear whether the region's native ecosystems were more resilient to climate change than current ecosystems, and whether they would provide sustainable management options if restored. We simulated vegetation with the L sub(AND) C sub(LIM) model, using present-day climate as well as future climate-change scenarios, in three representative areas that encompass a broad range of Mediterranean conditions and vegetation types. Sedimentary pollen records that document now-extinct forests help to validate the simulations. Forests modeled under present climate closely resemble the extinct forests when human disturbance is limited; under future scenarios, characterized by increased temperatures and decreased precipitation, extinct forests are projected to re-emerge. When combined with modeling, paleoecological evidence reveals the potential of native vegetation to re-establish under current and future climate conditions, and provides a template for novel management strategies to maintain forest productivity and biodiversity in a warmer and drier future.

However, photosynthesis of Ecklonia sporophytes was severely inhibited under a combination of high temperature (20[degrees]C) and 1000 ppm CO sub(2) concentration at the two photon irradiance levels. The growth of gametophytes was maximal at the combination of 380 ppm (present seawater CO sub(2) concentration) and 25[degrees]C. Minimal growth of gametophytes occurred at enriched pCO sub(2) concentration levels (750, 1000 ppm) and high temperature of 25[degrees]C. The present results imply that climate change which is increasing seawater temperature and pCO sub(2) concentration might diminish Ecklonia cava kelp beds because of a reduction in recruitments caused by the growth inhibition of gametophytes at high pCO sub(2) concentration. In addition, the effects of increased temperature and pCO sub(2) concentration were different between generations - revealing an enhancement in the photosynthesis of sporophytes and a reduction in the growth of gametophytes.

As an addition to current diagnostic methods for desert tortoises, we have developed the first leukocyte gene transcription biomarker panel for the desert tortoise (Gopherus agassizii), enhancing the ability to identify specific environmental conditions potentially linked to declining animal health. Blood leukocyte transcript profiles have the potential to identify physiologically stressed animals in lieu of clinical signs. For desert tortoises, the gene transcript profile included a combination of immune or detoxification response genes with the potential to be modified by biological or physical injury and consequently provide information on the type and magnitude of stressors present in the animal's habitat. Blood from 64 wild adult tortoises at three sites in Clark County, NV, and San Bernardino, CA, and from 19 captive tortoises in Clark County, NV, was collected and evaluated for genes indicative of physiological status. Statistical analysis using a priori groupings indicated significant differences among groups for several genes, while multidimensional scaling and cluster analyses of transcription C sub(T) values indicated strong differentiation of a large cluster and multiple outlying individual tortoises or small clusters in multidimensional space. These analyses highlight the effectiveness of the gene panel at detecting environmental perturbations as well as providing guidance in determining the health of the desert tortoise.

We tested these predictions using acoustic telemetry of 2 to 4 kg striped bass (Morone saxatilis Walbaum) and high-resolution spatial water quality sampling in the Patuxent River, a sub-estuary of the Chesapeake Bay, during 2008 and 2009. Striped bass avoided hypoxic (dissolved oxygen less than or equal to 2 mg.l super(-1)) subpycnocline waters, but frequently occupied habitats with high temperatures (>25 degree C) in the summer months, as cooler habitats were typically not available. Using traditional concepts of the seasonal thermal-niche oxygen-squeeze, most of the Patuxent estuary would be considered unsuitable habitat for adult striped bass during summer. Application of a bioenergetics model revealed that habitats selected by striped bass during summer would support positive growth rates assuming fish could feed at one-half of maximum consumption. Occupancy of the estuary during summer by striped bass in this study was likely facilitated by sufficient prey and innate tolerance of high temperatures by sub-adult fish of the size range that we tagged. Our results help extend the thermal-niche oxygen-squeeze hypothesis to native populations of striped bass in semi-enclosed coastal systems. Tolerance of for supraoptimal temperatures in our study supports recent suggestions by others that the thermal-niche concept for striped bass should be revised to include warmer temperatures.

During times of nutritional restriction, physiological trade-offs can induce periods of immune suppression, thereby increasing susceptibility to infectious disease. Our goal was to provide a conceptual framework describing how the endemic level bovine brucellosis (Brucella abortus) may be maintained in Yellowstone bison based on the seasonality of food resources and the life-history strategies of the host and pathogen. Our analysis was based on active B. abortus infection (measured via bacterial culture), nutritional indicators (measured as metabolites and hormones in plasma), and carcass measurements of 402 slaughtered bison. Data from Yellowstone bison were used to investigate (1) whether seasonal changes in diet quality affect nutritional condition and coincide with the reproductive needs of female bison; (2) whether active B. abortus infection and infection intensities vary with host nutrition and nutritional condition; and (3) the evidence for seasonal changes in immune responses, which may offer protection against B. abortus, in relation to nutritional condition. Female bison experienced a decline in nutritional condition during winter as reproductive demands of late gestation increased while forage quality and availability declined. Active B. abortus infection was negatively associated with bison age and nutritional condition, with the intensity of infection negatively associated with indicators of nutrition (e.g., dietary protein and energy) and body weight. Data suggest that protective cell-mediated immune responses may be reduced during the B. abortus transmission period, which coincides with nutritional insufficiencies and elevated reproductive demands during spring. Our results illustrate how seasonal food restriction can drive physiological trade-offs that suppress immune function and create infection and transmission opportunities for pathogens. Susceptibility to infectious disease may be influenced by the seasonal availability of food resources. In Yellowstone bison, active brucellosis infection was negatively associated with bison age and nutritional condition, with infection intensities most pronounced in young animals. Our results illustrate how seasonal food restriction might drive physiological trade-offs, which suppress immune function and create infection and transmission opportunities for pathogens.

We used 3 methods to examine sedimentation: 1) depth-integrated base-flow sampling, 2) repeat channel-surveys, and 3) sediment-accumulation pads. During base flow, Piedmont ponds exported sediment and Coastal Plain ponds had little or no effect on downstream suspended-sediment concentration. Most ponds accumulated sediment within the channel until dam breaching. Ponds inundating the floodplain trapped more sediment. Ponds of varying configuration trapped sediment differently. Mean floodplain accretion rates in these beaver ponds (2002-2003: 20 mm/yr 2003-2005: 15 mm/yr) greatly exceeded the mean deposition rate of similar unimpounded streams in these areas. Intact Piedmont ponds trapped 11 m3/yr on the floodplain and 77 m3/yr in the channel. Intact Coastal Plain ponds trapped 107 m3/yr on the floodplain and 8 m3/yr in the channel.

Winds off Huntington Beach CA are the dominant forcing for currents over the nearshore region of the shelf (water depths less than 20m). Winds control about 50-70% of the energy in nearshore alongshelf surface currents. The wind-driven current amplitudes are also anomalously high. For a relatively weak 1dyne/cm2 wind stress, the alongshelf surface current amplitudes in this region can reach 80cm/s or more. Mid-depth current amplitudes for the same wind stress are around 30-40cm/s. These wind-driven surface current amplitudes are much larger than previously measured over other nearshore shelf regions, perhaps because this program is one of the few that measured currents within a meter of the surface. The near-bed cross-shelf currents over the nearshore region of the Huntington Beach shelf have an Ekman response to winds in that they upwell (downwell) for down (up) coast winds. This response disappears further offshore. Hence, there is upwelling in the SCB, but it does not occur across the entire shelf. Subthermocline water in the nearshore region that may contain nutrients and plankton move onshore when winds are southeastward, but subthermocline water over the shelf break is not transported to the beach. The currents over the outer shelf are not predominately controlled by winds, consistent with previous reports.

Results show that NH deficit increased dramatically near the year 2000 during both the cool (October through March) and warm (April through September) seasons. The increase in water deficit near 2000 coincides with a substantial increase in NH temperature and PET. The most pronounced increases in deficit occurred for the latitudinal band from 0 to 40 degree N. These results indicate that global warming has increased the water deficit in the NH and that the increase since 2000 is unprecedented for the 1905 through 2009 period. Additionally, coincident with the increase in deficit near 2000, mean NH runoff also increased due to increases in P. We explain the apparent contradiction of concurrent increases in deficit and increases in runoff.

An existing groundwater flow model coupled with an advective transport simulation of the Salt Lake Valley, Utah (USA), is adapted for advective transport, and effective porosity is adjusted until simulated tritium concentrations match concentrations in samples from wells. Two calibration approaches are used: a "complex" highly parameterized porosity field and a "simple" parsimonious model of porosity distribution. The use of an atmospheric tracer (tritium in this case) and apparent ages (from tritium/helium) in model calibration also are discussed. Of the models tested, the complex model (with tritium concentrations and tritium/helium apparent ages) performs best. Although tritium breakthrough curves simulated by complex and simple models are very generally similar, and there is value in the simple model, the complex model is supported by a more realistic porosity distribution and a greater number of estimable parameters. Culling the best quality data did not lead to better calibration, possibly because of processes and aquifer characteristics that are not simulated. Despite many factors that contribute to shortcomings of both the models and the data, useful information is obtained from all the models evaluated. Although any particular prediction of tritium breakthrough may have large errors, overall, the models mimic observed trends.Original Abstract: Les merites relatifs de la complexite des modeles et des types d'observations utilisees dans la calibration des modeles sont compares. Un modele existant d'ecoulement des eaux souterraines couple a une simulation du transport advectif de la vallee du Lac Sale, Utah (Etats-Unis d'Amerique), est adapte pour le transport advectif, et la porosite efficace est ajustee jusqu'a ce que les concentrations simulees en tritium coincident aux concentrations des echantillons provenant des puits. Deux approches de calage sont employees: un champ de porosite "complexe", fortement parametre et un modele parcimonieux "simple" de distribution de la porosite. L'utilisation d'un traceur atmospherique (tritium dans ce cas-ci) et des ages apparents (a partir du rapport tritium/helium) dans le calage de modeles sont egalement discutes. Des deux modeles examines, le modele complexe (avec des concentrations en tritium et des ages apparents du rapport tritium/helium) fournit les meilleurs resultats. Bien que les courbes de percee de tritium simulees par les modeles complexes et simples soient tres generalement semblables, et malgre l'interet du modele simple, le modele complexe est soutenu par une distribution plus realiste de porosite et un plus grand nombre de parametres estimables. Collecter les donnees de meilleure qualite n'a pas mene a ameliorer le calage, probablement en raison des processus et des caracteristiques des aquiferes qui ne sont pas simules. En depit de beaucoup de facteurs qui contribuent aux imperfections des modeles et des donnees, une information utile est obtenue a partir de tous les modeles evalues. Bien que n'importe quelle prevision particuliere de percee de tritium puisse avoir de larges erreurs, finalement, les modeles simulent bien les tendances observees.

The associated groundwater-level declines have led the Los Angeles County Superior Court of California to recently rule that the Antelope Valley groundwater basin is in overdraft, i.e., annual pumpage exceeds annual recharge. Natural recharge consists primarily of mountain-front recharge and is an important component of the total groundwater budget in Antelope Valley. Therefore, natural recharge plays a major role in the Court's decision. The exact quantity and distribution of natural recharge is uncertain, with total estimates from previous studies ranging from 37 to 200 gigaliters per year (GL/year). In order to better understand the uncertainty associated with natural recharge and to provide a tool for groundwater management, a numerical model of groundwater flow and land subsidence was developed. The transient model was calibrated using PEST with water-level and subsidence data; prior information was incorporated through the use of Tikhonov regularization. The calibrated estimate of natural recharge was 36 GL/year, which is appreciably less than the value used by the court (74 GL/year). The effect of parameter uncertainty on the estimation of natural recharge was addressed using the Null-Space Monte Carlo method. A Pareto trade-off method was also used to portray the reasonableness of larger natural recharge rates. The reasonableness of the 74 GL/year value and the effect of uncertain pumpage rates were also evaluated. The uncertainty analyses indicate that the total natural recharge likely ranges between 34.5 and 54.3 GL/year.Original Abstract: Les eaux souterraines ont fourni 50-90 % de l'approvisionnement total en eau dans la vallee d'Antelope, en Californie (Etats Unis d'Amerique). Les baisses de niveau des eaux souterraines associees ont conduit la Cour superieure de Californie du comte de Los Angeles a publie recemment une regle stipulant que le bassin des eaux souterraines de la vallee d'Antelope est dans une situation de surexploitation, a savoir que le pompage annuel excede la recharge annuelle. La recharge naturelle se compose principalement de la recharge sur la chaine de montagnes et est une composante importante du bilan total des eaux souterraines e la vallee d'Antelope. Par consequent, la recharge naturelle joue un role majeur dans la decision de la Cour. La quantite exacte ainsi que la distribution de la recharge naturelle sont incertaines, les estimations globales des etudes anterieures etant comprises entre 37 et 200 gigalitres par an (GL/an). Afin de mieux comprendre l'incertitude associee a la recharge naturelle et de fournir un outil pour la gestion des eaux souterraines, un modele numerique d'ecoulement souterrain et des affaissements de terrain a ete developpe. Le modele transitoire a ete calibre en utilisant PEST avec les donnees de niveaux d'eau et de subsidence; l'information prealable a ete incorporee grace a l'utilisation de la regularisation de Tikhonov. L'estimation calibree de la recharge naturelle etait de 36 GL/an, ce qui est nettement inferieur a la valeur utilisee par la Cour (74 GL/an). L'effet de l'incertitude des parametres sur l'estimation de la recharge naturelle a ete aborde en utilisant la methode de Monte Carlo Null-Space. La methode de compromis de Pareto a egalement ete utilisee pour depeindre le caractere raisonnable des plus grands taux de recharge naturelle. Le caractere raisonnable de la valeur de 74 GL/an et l'effet des debits incertains des pompages ont egalement ete evalues. Les analyses d'incertitude indiquent que la recharge naturelle totale varie entre 34.5 et 54.3 GL/an.

Ecological differences have been identified as a possible reason for the generally poorer body condition and reproduction of Beaufort polar bears compared to those from the Chukchi, but the influence of exposure to other stressors remains unknown. We use molecular technology, quantitative PCR, to identify gene transcription differences among polar bears from the Beaufort and Chukchi Seas as well as captive healthy polar bears. We identified significant transcriptional differences among a priori groups (i.e., captive bears, SB 2012, SB 2013, CS 2013) for ten of the 14 genes of interest (i.e., CaM, HSP70, CCR3, TGF beta , COX2, THR alpha , T-bet, Gata3, CD69, and IL17); transcription levels of DR beta , IL1 beta , AHR, and Mx1 did not differ among groups. Multivariate analysis also demonstrated separation among the groups of polar bears. Specifically, we detected transcript profiles consistent with immune function impairment in polar bears from the Beaufort Sea, when compared with Chukchi and captive polar bears. Although there is no strong indication of differential exposure to contaminants or pathogens between CS and SB bears, there are clearly differences in important transcriptional responses between populations. Further investigation is warranted to refine interpretation of potential effects of described stress-related conditions for the SB population.

Bench- and pilot-scale testing at about 3 and 13,500 L, respectively, demonstrated that total chlorinated solvent removal to less than the permitted discharge limit of 100 mu g/L. Various planned and unexpected upsets, interruptions, and changes demonstrated the robustness and reliability of the bioreactor system, which handled the operational variations with no observable change in performance. Key operating parameters included an adequately long hydraulic retention time for the surface area, a constant supply of electron donor, pH control with a buffer to minimize pH variance, an oxidation reduction potential of approximately -200 millivolts or lower, and a well-adapted biomass capable of degrading the full suite of chlorinated solvents in the groundwater. Results indicated that the current discharge criteria can be met using a bioreactor technology that is less complex and has less downtime than the sorption based technology currently being used to treat the groundwater.

In the Arikareean, about 6 million years later, the enigmatic primate Ekgmowechashala appeared in the Great Plains and Oregon. This taxon shows little resemblance to other North American primates and its phylogenetic position has long been debated. New material of this taxon allows a revised assessment of its age and how it is related to other primates. Recently collected Ekgmowechashala specimens from the Turtle Cove Member of the John Day Formation in Oregon are described. These specimens are compared to previously collected material from South Dakota and Nebraska, as well as other fossil primates from North America and Asia. Study of the John Day material allows diagnosis of a new, distinct species. Comparison of Ekgmowechashala to a pair of recently described Asian primates, Muangthanhinius and Bugtilemur, suggests that it is a strepsirrhine adapiform, rather than an omomyid. The well-defined stratigraphy and dated marker beds of the Turtle Cove Member provide a refined age for Ekgmowechashala occurrences in Oregon, during the Oligocene (early Arikareean). The age and morphology of these ekgmowechashaline taxa suggest that the group originated in Asia and dispersed to North America in the Oligocene, after the extinction of other primates in North America. Contemporaneous occurrences of Ekgmowechashala in Oregon and the Great Plains indicate the last non-human primates vanished in North America about 26 million years ago.

Barnegat Bay-Little Egg Harbor (BB-LEH), New Jersey, is a lagoonal back-barrier estuary that is subject to anthropogenic pressures including nutrient loading, eutrophication, and subsequent declines in water quality. A combination of hydrodynamic and particle tracking modeling was used to identify the mechanisms controlling flushing, residence time, and spatial variability of particle retention. The models demonstrated a pronounced northward subtidal flow from Little Egg Inlet in the south to Pt. Pleasant Canal in the north due to frictional effects in the inlets, leading to better flushing of the southern half of the estuary and particle retention in the northern estuary. Mean residence time for BB-LEH was 13 days but spatial variability was between 0 and 30 days depending on the initial particle location. Mean residence time with tidal forcing alone was 24 days (spatial variability between 0 and 50 days); the tides were relatively inefficient in flushing the northern end of the Bay. Scenarios with successive exclusion of physical processes from the models revealed that meteorological and remote offshore forcing were stronger drivers of exchange than riverine inflow. Investigations of water quality and eutrophication should take into account spatial variability in hydrodynamics and residence time in order to better quantify the roles of nutrient loading, production, and flushing.

A multitude of theoretical equations describe these dynamics, from predator and prey to parasite and host. Lafferty et al. show that all forms of these relationships come down to fundamental consumer-resource interactions. Derived from the myriad complex interactions, a simple model can accommodate any such interaction, simplifying past models into a general theory of eat and be eaten.Science, this issue p. 854 Food-web dynamics arise from predator-prey, parasite-host, and herbivore-plant interactions. Models for such interactions include up to three consumer activity states (questing, attacking, consuming) and up to four resource response states (susceptible, exposed, ingested, resistant). Articulating these states into a general model allows for dissecting, comparing, and deriving consumer-resource models. We specify this general model for 11 generic consumer strategies that group mathematically into predators, parasites, and micropredators and then derive conditions for consumer success, including a universal saturating functional response. We further show how to use this framework to create simple models with a common mathematical lineage and transparent assumptions. Underlying assumptions, missing elements, and composite parameters are revealed when classic consumer-resource models are derived from the general model.

2016-018448 AB - Numerous streams, with a drainage area of a few square kilometers, draining the south flank of the Santa Ynez Range in Southern California are characterized by steep boulder-bed, debris-flow-dominated channels. Rattlesnake Creek is a good example. Approximately 90% of the stored sediment in the stream valley is stable debris flow deposits found in debris flow terraces and levees adjacent to the channel. The remaining 10% of stored sediment resides in the active channel, where the channel morphology is dominated by large boulders (1 to 4 + m in diameter) derived from debris flows or rock fall that, along with bedrock outcrops, form rock or boulder transverse ribs with frequent step-pools. The dominant channel pool morphology is the step-pool, which accounts for most of the pools and approximately 30% of relief (drop in elevation) through the study reaches. Less common pool types identified in the study reaches include forced pools that result from convergence of flow with scour between LBREs (large boulder roughness elements) and bedrock outcrop along the channel at near bankfull discharge. The LBREs and boulders in step-pools armor the channel and are primary controls on channel morphology and gradient. Rock strength is a secondary control on channel morphology, location, and abundance of pools. We hypothesize that step-pools, when inundated with sand and fine gravel from a disturbance (such as wildfire) during a flow event, fill near bankfull stage and scour on falling stage below bankfull when unit stream power is a maximum over the step. Thus, as with forced pools, step-pool maintenance depends on a specific pattern of discharge and process. The process of scour during falling stage reestablishes step-pools during moderate flows, following disturbance. Abstract Copyright (2015) Elsevier, B.V.

It should be accounted for in geomorphic studies, river restoration, dam removal, and channel maintenance projects. Recently, one-dimensional and two-dimensional flows and mobile-bed numerical models have become useful tools for predicting morphological responses to stream modifications. Most, however, either ignore bank failure mechanisms or implement only simple ad hoc methods. In this study, a coupled model is developed that incorporates a process-based bank stability model within a recently developed two-dimensional mobile-bed model to predict bank retreat. A coupling procedure that emphasizes solution robustness as well as ease-of-use is developed and described. The coupled model is then verified and validated by applying it to multilayer cohesive bank retreat at a bend of Goodwin Creek, Mississippi. Comparisons are made between the predicted and measured data, as well as results of a previous modeling study. On one hand, the study demonstrates that the use of two-dimensional mobile-bed models leads to promising improvements over that of one-dimensional models. It therefore encourages the use of multidimensional models in bank erosion predictions. On the other hand, the study also identifies future research needs in order to improve numerical modeling of complex streams. The developed model is shown to be robust and easy to apply; it may be used as a practical tool to predict bank erosion caused by fluvial and geotechnical processes.

2015-099196 AB - The mechanisms of late Pleistocene megafauna extinctions remain fiercely contested, with human impact or climate change cited as principal drivers. We compared ancient DNA and radiocarbon data from 31 detailed time series of regional megafaunal extinctions and replacements over the past 56,000 years with standard and new combined records of Northern Hemisphere climate in the late Pleistocene. Unexpectedly, rapid climate changes associated with interstadial warming events are strongly associated with the regional replacement or extinction of major genetic clades or species of megafauna. The presence of many cryptic biotic transitions before the Pleistocene/Holocene boundary revealed by ancient DNA confirms the importance of climate change in megafaunal population extinctions and suggests that metapopulation structures necessary to survive such repeated and rapid climatic shifts were susceptible to human impacts.

We present super(238)U- super(230)Th crystallization ages and trace-element compositions of the interiors and surfaces (i.e. unpolished rims) of single zircon crystals from each rhyolite. We compare these zircon data with super(238)U- super(230)Th crystallization ages of bulk sanidine separates coupled with chemical and isotopic data from single sanidine crystals. Zircon age and trace-element data demonstrate that the magma reservoir that sourced the Central Plateau Member rhyolites was long-lived (150-250kyr) and genetically related to the preceding episode of magmatism, which occurred c. 256ka. The interiors of most zircons in each rhyolite were inherited from unerupted material related to older stages of Central Plateau Member magmatism or the preceding late Upper Basin Member magmatism (i.e. are antecrysts). Conversely, most zircon surfaces crystallized near the time of eruption from their host liquids (i.e. are autocrystic). The repeated recycling of zircon interiors from older stages of magmatism demonstrates that sequentially erupted Central Plateau Member rhyolites are genetically related. Sanidine separates from each rhyolite yield super(238)U- super(230)Th crystallization ages at or near the eruption age of their host magmas, coeval with the coexisting zircon surfaces, but are younger than the coexisting zircon interiors. Chemical and isotopic data from single sanidine crystals demonstrate that the sanidines in each rhyolite are in equilibrium with their host melts, which considered along with their near-eruption crystallization ages suggests that nearly all Central Plateau Member sanidines are autocrystic. The paucity of antecrystic sanidine crystals relative to antecrystic zircons requires a model in which eruptible rhyolites are generated by extracting melt and zircons from a long-lived mush of immobile crystal-rich magma. In this process the larger sanidine crystals remain trapped in the locked crystal network. The extracted melts (plus antecrystic zircon) amalgamate into a liquid-dominated (i.e. eruptible) magma body that is maintained as a physically distinct entity relative to the bulk of the long-lived crystal mush. Zircon surfaces and sanidines in each rhyolite crystallize after melt extraction and amalgamation, and their ages constrain the residence time of eruptible magmas at Yellowstone. Residence times of the large-volume rhyolites (40-70km super(3)) are less than or equal to 1kyr (conservatively <6kyr), which suggests that large volumes of rhyolite can be generated rapidly by extracting melt from a crystal mush. Because the lifespan of the crystal mush that sourced the Central Plateau Member rhyolites is two orders of magnitude longer than the residence time of eruptible magma bodies within the reservoir, it is apparent that the Yellowstone magma reservoir spends most of its time in a largely crystalline (i.e. uneruptible) state, similar to the present-day magma reservoir, and that eruptible magma bodies are ephemeral features.

Here, we characterize several major themes emerging from this research and highlight some of the uptake of this work in both scientific and public spheres. Underpinning much of this research is the recognition that water resources are expected to undergo substantial changes based on the global warming that results primarily from fossil energy-based carbon emissions. At the same time, the production of electricity from fossil fuels, nuclear power, and some renewable technologies (biomass, geothermal and concentrating solar power) can be highly water-intensive. Energy choices now and in the near future will have a major impact not just on the global climate, but also on water supplies and the resilience of energy systems that currently depend heavily on them.

Single-Story Structures AN - 1786174784; PQ0002500819 AB - The California Building Code requires at least two ground motion components for the three-dimensional (3-D) response history analysis (RHA) of structures. For near-fault sites, these records should be rotated to fault-normal/ fault-parallel (FN/FP) directions, and two RHA analyses should be performed separately. This approach is assumed to lead to two sets of responses that envelope the range of possible responses over all non-redundant rotation angles. This assumption is examined here using 3-D computer models of single-story structures having symmetric and asymmetric plans subjected to a suite of bi-directional earthquake ground motions. The influence that the rotation angle has on several engineering demand parameters is investigated in linear and nonlinear domains to evaluate the use of the FN/FP directions, and the maximum direction (MD). The statistical evaluation suggests that RHAs should be conducted by rotating a set of records to the MD and FN/FP directions, and taking the maximum response values from these analyses as design values.

Multi-Story Structures AN - 1786166421; PQ0002500820 AB - The influence of the ground motion rotation angle on engineering demand parameters (EDPs) is examined in the companion paper based on three-dimensional (3-D) computer models of single-story structures. Further validations are performed here using 3-D models of nine-story buildings that have symmetric and asymmetric layouts subjected to a suite of bi-directional near-fault records with and without apparent velocity-pulses. The linear and nonlinear response-history analyses (RHAs) are used for evaluating the use of fault-normal and fault-parallel (FN/FP) directions and maximum-direction (MD) to rotate ground motions. This study suggests that individual ground motions rotated to MD or FN/FP directions not always provide conservative EDPs in nonlinear range, but often produce larger EDPs than as-recorded motions. In practice, when a suite of ground motions is used, nonlinear RHAs should be performed by rotating them to the MD and FN/FP directions, and maximum response values should be taken from these analyses as design values.

Thes storms, which typically occur several times each year in July-September, are often small in area, short-lived, and highly variable in intensity and geographic distribution. Thus, a rain gage network with high temporal resolution and spatial density, together with high-resolution stream sampling, are required to adequately characterize post-wildfire responses. We measured total suspended sediment, dissolved organic carbon (DOC), nitrate, and manganese concentrations that were 10-156 times higher downstream of a burned area compared to upstream during relatively common rainstorms, and water quality was sufficiently impaired to pose water-treatment concerns. Results from this study quantitatively demonstrate that water quality can be altered for several years after wildfire. Because the southwestern US is prone to wildfires and high-intensity rain storms, the role of storms in post-wildfire water-quality impacts must be considered when assessing water-quality vulnerability.

Current systems analysis practice is widespread and addresses the most challenging water issues of our times, including water scarcity and drought, climate change, providing water for food and energy production, decision making amid competing objectives, and bringing economic incentives to bear on water use. The emergence of public recognition and concern for the state of water resources provides an opportune moment for the field to reorient to meet the complex, interdependent, interdisciplinary, and global nature of today's water challenges. At present, water resources systems analysis is limited by low scientific and academic visibility relative to its influence in practice and bridled by localized findings that are difficult to generalize. The evident success of water resource systems analysis in practice (which is set out in this paper) needs in future to be strengthened by substantiating the field as the science of water resources that seeks to predict the water resources variables and outcomes that are important to governments, industries, and the public the world over. Doing so promotes the scientific credibility of the field, provides understanding of the state of water resources and furnishes the basis for predicting the impacts of our water choices.

An energy management system (EMS) integrates energy management into existing business systems, enabling organizations to better manage their energy, sustain achieved savings, and continuously improve energy performance. Governments are implementing various approaches to accelerate industry uptake of these systems, such as promoting compliance with the ISO 50001 energy management standard. This article explores three approaches in use: mandated programs (Japan), incentive programs (Sweden), and market-based certification programs (United States). The authors examine each of these three approaches by taking an in-depth look at one real-world example. For each example, the article identifies the specific program requirements, the larger context for the policy and role of government, existing drivers for corporate participation, key challenges and resources, and the available results (i.e., energy and cost savings and other benefits). Comparisons among these current, government-led models for accelerating the uptake of EMS should provide insight into the effectiveness and benefits of different government approaches and their supporting policies and resources. Governments can learn from the challenges faced, solutions devised, and lessons learned by others during implementation of these programs.

However, robust SWE estimates are observationally challenging, in part because SWE can vary abruptly over short distances in complex terrain due to interactions between topography and meteorological processes. In spring 2013, we measured snow accumulation on several glaciers around the Gulf of Alaska using both ground- and helicopter-based ground-penetrating radar surveys, complemented by extensive ground truth observations. We found that SWE can be highly variable (40% difference) over short spatial scales (tens to hundreds of meters), especially in the ablation zone where the underlying ice surfaces are typically rough. Elevation provides the dominant basin-scale influence on SWE, with gradients ranging from 115 to 400mm/100m. Regionally, total accumulation and the accumulation gradient are strongly controlled by a glacier's distance from the coastal moisture source. Multiple linear regressions, used to calculate distributed SWE fields, show that robust results require adequate sampling of the true distribution of multiple terrain parameters. Final SWE estimates (comparable to winter balances) show reasonable agreement with both the Parameter-elevation Relationships on Independent Slopes Model climate data set (9-36% difference) and the U.S. Geological Survey Alaska Benchmark Glaciers (6-36% difference). All the glaciers in our study exhibit substantial sensitivity to changing snow-rain fractions, regardless of their location in a coastal or continental climate. While process-based SWE projections remain elusive, the collection of ground-penetrating radar (GPR)-derived data sets provides a greatly enhanced perspective on the spatial distribution of SWE and will pave the way for future work that may eventually allow such projections. Key Points * SWE on Alaska's glaciers is broadly controlled by distance from moisture sources * SWE elevation gradients are steeper than measured in nonglacierized terrain * Thorough sampling of terrain parameters provides robust extrapolation JF - Journal of Geophysical Research: Earth Surface AU - McGrath, Daniel AU - Sass, Louis AU - O'Neel, Shad AU - Arendt, Anthony AU - Wolken, Gabriel AU - Gusmeroli, Alessio AU - Kienholz, Christian AU - McNeil, Christopher AD - USGS Alaska Science Center, Anchorage, Alaska, USA.

Disturbances have altered and reduced this ecosystem historically, but climate change may ultimately represent the greatest future risk. Improved ways to quantify, monitor, and predict climate-driven gradual change in this ecosystem is vital to its future management. We examined the annual change of Daymet precipitation (daily gridded climate data) and five remote sensing ecosystem sagebrush vegetation and soil components (bare ground, herbaceous, litter, sagebrush, and shrub) from 1984 to 2011 in southwestern Wyoming. Bare ground displayed an increasing trend in abundance over time, and herbaceous, litter, shrub, and sagebrush showed a decreasing trend. Total precipitation amounts show a downward trend during the same period. We established statistically significant correlations between each sagebrush component and historical precipitation records using a simple least squares linear regression. Using the historical relationship between sagebrush component abundance and precipitation in a linear model, we forecasted the abundance of the sagebrush components in 2050 using Intergovernmental Panel on Climate Change (IPCC) precipitation scenarios A1B and A2. Bare ground was the only component that increased under both future scenarios, with a net increase of 48.98km2 (1.1%) across the study area under the A1B scenario and 41.15km2 (0.9%) under the A2 scenario. The remaining components decreased under both future scenarios: litter had the highest net reductions with 49.82km2 (4.1%) under A1B and 50.8km2 (4.2%) under A2, and herbaceous had the smallest net reductions with 39.95km2 (3.8%) under A1B and 40.59km2 (3.3%) under A2. We applied the 2050 forecast sagebrush component values to contemporary (circa 2006) greater sage-grouse (Centrocercus urophasianus) habitat models to evaluate the effects of potential climate-induced habitat change. Under the 2050 IPCC A1B scenario, 11.6% of currently identified nesting habitat was lost, and 0.002% of new potential habitat was gained, with 4% of summer habitat lost and 0.039% gained. Our results demonstrate the successful ability of remote sensing based sagebrush components, when coupled with precipitation, to forecast future component response using IPCC precipitation scenarios. Our approach also enables future quantification of greater sage-grouse habitat under different precipitation scenarios, and provides additional capability to identify regional precipitation influence on sagebrush component response.

In light of this increased use, a review of the dye's behavior in freshwater systems is presented. Studies in the groundwater literature indicate that rhodamine WT is transported nonconservatively, with sorption removing substantial amounts of tracer mass. Column studies document a two-step breakthrough curve in which two structural isomers are chromatographically separated. Although the potential for nonconservative transport is acknowledged in the surface water literature, many studies assume that sorptive losses will not affect the characterization of physical transport processes. A literature review and modeling analysis indicates that this assumption is valid for quantification of physical properties that are based on the bulk of the tracer mass (traveltime), and invalid for the characterization of processes represented by the tracer tail (transient storage attributable to hyporheic exchange). Rhodamine WT should be considered nonconservative in the hyporheic zone due to nonconservative behavior demonstrated for similar conditions in groundwater. As such, rhodamine WT should not be used as a quantitative tracer in hyporheic zone investigations, including the study of long flow paths and the development of models describing hyporheic zone processes. Rhodamine WT may be used to qualitatively characterize storage in large systems, where there are few practical alternatives. Qualitative investigations should rely on early portions of the tracer profile, making use of the temporal resolution afforded by in situ fluorometry, while discarding later parts of the tracer profile that are adversely affected by sorption. Key Points: * Rhodamine WT is not a conservative tracer due to sorption onto solid surfaces * Rhodamine WT should not be used to quantify hyporheic zone processes * Qualitative use of rhodamine WT may be justified in large systems JF - Water Resources Research AU - Runkel, Robert L AD - United States Geological Survey, Boulder, Colorado, USA.

Zebra mussels clog water intakes for hydroelectric companies, harm unionid mussel species, and are believed to be a reservoir of avian botulism. Little is known about the digestive physiology of zebra mussels and unionid mussels. The enzymatic profile of the digestive glands of zebra mussels and native threeridge (Amblema plicata) and plain pocketbook mussels (Lampsilis cardium) are characterized using a commercial enzyme kit, api ZYM, and validated the kit with reagent-grade enzymes. A linear correlation was shown for only one of nineteen enzymes, tested between the api ZYM kit and a specific enzyme kit. Thus, the api ZYM kit should only be used to make general comparisons of enzyme presence and to observe trends in enzyme activities. Enzymatic trends were seen in the unionid mussel species, but not in zebra mussels sampled 32 days apart from the same location.Enzymatic classes, based on substrate, showed different trends, with proteolytic and phospholytic enzymes having the most change in relative enzyme activity.

This study investigates patterns of genetic structure and diversity in six species of freshwater mussels in the central Great Lakes region of Ontario, Canada. These species vary in their conservation status (endangered to not considered at risk), life history strategy, and dispersal capabilities. Evidence of historical genetic connectivity within rivers was ubiquitous across species and may reflect dispersal abilities of host fish. There was little to no signature of recent disturbance events or bottlenecks, even in endangered species, likely as a function of mussel longevity and historical population sizes (i.e., insufficient time for genetic drift to be detectable). Genetic structure was largely at the watershed scale suggesting that population augmentation via translocation within rivers may be a useful conservation tool if needed, while minimizing genetic risks to recipient sites. Recent interest in population augmentation via translocation and propagation may rely on these results to inform management of unionids in the Great Lakes region.

We assessed the potential for future land use conversion on land surrounding existing protected areas in California's twelve ecoregions, utilizing annual, spatially explicit (250 m) scenario projections of land use for 2006-2100 based on the Intergovernmental Panel on Climate Change Special Report on Emission Scenarios to examine future changes in development, agriculture, and logging. We calculated a conversion threat index (CTI) for each unprotected pixel, combining land use conversion potential with proximity to protected area boundaries, in order to identify ecoregions and protected areas at greatest potential risk of proximal land conversion. Our results indicate that California's Coast Range ecoregion had the highest CTI with competition for extractive logging placing the greatest demand on land in close proximity to existing protected areas. For more permanent land use conversions into agriculture and developed uses, our CTI results indicate that protected areas in the Central California Valley and Oak Woodlands are most vulnerable. Overall, the Eastern Cascades, Central California Valley, and Oak Woodlands ecoregions had the lowest areal percent of protected lands and highest conversion threat values. With limited resources and time, rapid, landscape-level analysis of potential land use threats can help quickly identify areas with higher conversion probability of future land use and potential changes to both habitat and potential ecosystem reserves. Given the broad range of future uncertainties, LULC projections are a useful tool allowing land managers to visualize alternative landscape futures, improve planning, and optimize management practices.

AN - 1680188617; 25828407 AB - The potential for increases in stream temperature across many spatial and temporal scales as a result of climate change can pose a difficult challenge for environmental managers, especially when addressing thermal requirements for sensitive aquatic species. This study evaluates simulated changes to the thermal regime of three northern Wisconsin streams in response to a projected changing climate using a modeling framework and considers implications of thermal stresses to the fish community. The Stream Network Temperature Model (SNTEMP) was used in combination with a coupled groundwater and surface water flow model to assess forecasts in climate from six global circulation models and three emission scenarios. Model results suggest that annual average stream temperature will steadily increase approximately 1.1 to 3.2°C (varying by stream) by the year 2100 with differences in magnitude between emission scenarios. Daily mean stream temperature during the months of July and August, a period when cold-water fish communities are most sensitive, showed excursions from optimal temperatures with increased frequency compared to current conditions. Projections of daily mean stream temperature, in some cases, were no longer in the range necessary to sustain a cold water fishery. Published by Elsevier B.V.

We analyzed presence/absence data derived from digital distribution maps for trees, amphibians, large mammals, small mammals, migrant birds, and resident birds using three statistical analyses of classification accuracy (Analysis of Similarity, Canonical Analysis of Principal Coordinates, and Classification Strength). The classifications were roughly comparable in classification accuracy, with Omernik Revised showing the best overall performance. Trees showed the strongest fidelity to the classifications, and large mammals showed the weakest fidelity. We discuss the implications for regional biogeography and describe how intermediate resolution ecoregional classifications may be appropriate for use as natural areas management domains.

It is the leading cause of eosinophilic meningitis and is a zoonotic health risk. We confirmed the presence of A. cantonensis using species-specific, quantitative PCR in 18 of 50 (36%) giant African land snails (Lissachatina fulica) collected from Miami, Florida, US in May 2013. These snails were collected from seven of 21 core areas that the Florida Department of Agriculture and Consumer Services monitor weekly. Rat lungworms have not previously been identified in these areas. Duplicate DNA extractions of foot muscle tissue from each snail were tested. Of the seven core areas we examined, six were positive for A. cantonensis and prevalence of infection ranged from 27% to 100%. Of the 18 positive snails, only five were positive in both extractions. Our results confirm an increase in the range and prevalence of rat lungworm infection in Miami. We also emphasize the importance of extracting sufficient host tissue to minimize false negatives.

Toward those ends, we systematically examined 300 carcasses of endangered Hawaiian Geese (Nene; Branta sandvicensis) from Hawaii, Maui, Molokai, and Kauai between 1992 and 2013. The most common cause of death was emaciation, followed by trauma (vehicular strikes and predation), and infectious/inflammatory diseases of which toxoplasmosis (infection with Toxoplasma gondii) predominated. Toxicoses were less common and were dominated by lead poisoning or botulism. For captive birds, inflammatory conditions predominated, whereas emaciation, trauma, and inflammation were common in free-ranging birds. Mortality patterns were similar for males and females. Trauma predominated for adults, whereas emaciation was more common for goslings. Causes of death varied among islands, with trauma dominating on Molokai, emaciation and inflammation on Kauai, emaciation on Hawaii, and inflammation and trauma on Maui. Understanding habitat or genetic-related factors that predispose Nene (particularly goslings) to emaciation might reduce the impact of this finding. In addition, trauma and infection with T. gondii are human-related problems that may be attenuated if effectively managed (e.g., road signs, enforcement of speed limits, feral cat [Felis catus] control). Such management actions might serve to enhance recovery of this endangered species.

Ongoing deformation is concentrated within the caldera. We analyze this deformation using a combination of GPS and InSAR (TerraSAR-X) data processed with a persistent scatterer technique. The extension rate of the dome-crossing baseline during this episode (CA99 to KRAC) is 1cm/yr, similar to past inflation episodes (1990-1995 and 2002-2003), and about a tenth of the peak rate observed during the 1997 unrest. The current deformation is well modeled by the inflation of a prolate spheroidal magma reservoir 7km beneath the resurgent dome, with a volume change of 610 super(6)m super(3)/yr from 2011.7 through the end of 2014. The current data cannot resolve a second source, which was required to model the 1997 episode. This source appears to be in the same region as previous inflation episodes, suggesting a persistent reservoir.

AN - 1777468440; 2016-027503 AB - This is the first detailed report of vertebrate tracks from alluvial plain deposits of the Boulder Creek Formation (Lower Cretaceous: middle to ?upper Albian) from outcrop exposures in northeastern British Columbia. Several in situ dinosaur tracks observed in vertical section are described, as well as the recovery and description of an isolated track slab discovered in the Boulder Gardens recreation area south of Tumbler Ridge, British Columbia. The vertebrate ichnites consist of three small tridactyl theropod dinosaur prints, one tetradactyl ornithopod print, and 72 small tridactyl tracks of avian affinity which are described as a new ichnotaxon herein. The avian prints are small (under 30 mm length) and are characterised by a large divarication between digits II and III and comparatively lesser divarication between digits III and IV. The pace and stride are short and the pace angulation is high. The tracks are similar to those produced by extant shorebirds and the track-maker likely occupied a similar niche. The avian prints are described herein as a new ichnotaxon, Paxavipes babcockensis ichnogen. et isp. nov. Two of the theropod footprints are identified as Irenichnites gracilis, an ichnotaxon described in 1932 by C.M. Sternberg from the Lower Cretaceous (Aptian) Gething Formation near Hudson's Hope, British Columbia. One of the Irenichnites gracilis prints displays skin impressions associated with the digital pads of digit III and the metatarsal pad. This is the first record of skin impressions from prints of Irenichnites gracilis. The ornithopod track is partial and unidentifiable to a particular ichnotaxon, but displays skin impressions on the metatarsal pad and at the base of the second digit impression. The skin impressions from the ornithopod track differ from the Irenichnites gracilis skin impressions. Abstract Copyright (2015) Elsevier, B.V.

The osteoderm is of a size and pit pattern that resembles the large alligatoroid Deinosuchus but the thickness and shape of the bone suggest possible affinities with the goniopholidid or pholidosaurid crocodyliform material known from the Campanian of southern Utah; smaller, similar osteoderms from the formation may suggest that this form was relatively abundant as juveniles. Overall faunal similarities of the Williams Fork Formation are closest to the Kaiparowits Formation of southern Utah also, but few lower level taxa can be confirmed from the Williams Fork that are not also known from other areas north and south, suggesting that the Williams Fork vertebrate fauna comes from the southern end of a transition zone between possible latitudinal provinces of Laramidia.

Existing LANDFIRE disturbance data from 1999 to 2010 are available and current efforts will produce disturbance data through 2012. A tiling and compositing approach was developed to produce bi-annual images optimized for change detection. A tiled grid of 10,000 x 10,000 30 m pixels was defined for CONUS and adjusted to consolidate smaller tiles along national borders, resulting in 98 non-overlapping tiles. Data from Landsat-5,-7, and -8 were re-projected to the tile extents, masked to remove clouds, shadows, water, and snow/ice, then composited using a cosine similarity approach. The resultant images were used in a change detection algorithm to determine areas of vegetation change. This approach enabled more efficient processing compared to using single Landsat scenes, by taking advantage of overlap between adjacent paths, and allowed an automated system to be developed for the entire process.

During the Medieval Climate Anomaly ( approximately A.D. 900-1300) the four basins collectively experienced 13 large floods compared to nine large floods in the previous 800 years, including the largest floods of the last 2000 years for two of the four basins. This high concentration of extreme floods is likely caused by one or more of the following: 1) instability of air masses caused by stronger than normal westerlies; 2) larger or more frequent hurricanes in the Gulf of Mexico and Atlantic Ocean; and/or 3) reduced land covering vegetation or increased forest fires caused by persistent regional drought.

The loss of even small numbers of individuals may adversely affect fragile populations, but typically, few (if any) carcasses are observed during monitoring. Fatality monitoring at wind-power facilities commonly' involves conducting experiments to estimate the probability (g) an individual will be observed, accounting for the possibilities that it falls in an unsearched area, is scavenged prior to detection, or remains undetected even when present. We apply the method to data collected at a wind-power facility where scheduled searches yielded X = 0 raptor carcasses.

Accordingly, large investments have been made to restore passage at these crossings, but often without estimation of population-level benefits. Here, we describe a broad-scale approach to quantifying the effectiveness of passage restoration in terms interpretable at population levels, namely numbers of fish and length of stream gained through restoration, by sampling abundance in a study design that accounts for variable bio-geographic species pools, variable stream and barrier configurations, and variable probabilities of capture and detectability for multiple species. Although our framework can address the question of effectiveness in a broad array of stream and crossing configurations, much stronger inferences would be possible if future restoration efforts were designed to address the limitations we encountered in this study, particularly the lack of available information on crossings and species presence prior to restoration, and nonrandom selection of crossings to be replaced.

Previous efforts to forecast climate effects on brook trout (Salvelinus fontinalis) habitat have generally assumed uniform air-water temperature relationships over large areas that cannot account for groundwater inputs and other processes that operate at finer spatial scales. We developed regression models that accounted for groundwater influences on thermal sensitivity from measured air-water temperature relationships within forested watersheds in eastern North America (Shenandoah National Park, Virginia, USA, 78 sites in nine watersheds). We used these reach-scale models to forecast climate change effects on stream temperature and brook trout thermal habitat, and compared our results to previous forecasts based upon large-scale models. Observed stream temperatures were generally less sensitive to air temperature than previously assumed, and we attribute this to the moderating effect of shallow groundwater inputs. Predicted groundwater temperatures from air-water regression models corresponded well to observed groundwater temperatures elsewhere in the study area. Predictions of brook trout future habitat loss derived from our fine-grained models were far less pessimistic than those from prior models developed at coarser spatial resolutions. However, our models also revealed spatial variation in thermal sensitivity within and among catchments resulting in a patchy distribution of thermally suitable habitat. Habitat fragmentation due to thermal barriers therefore may have an increasingly important role for trout population viability in headwater streams. Our results demonstrate that simple adjustments to air-water temperature regression models can provide a powerful and cost-effective approach for predicting future stream temperatures while accounting for effects of groundwater.

We applied structured decision making (SDM) to guide selection of monitoring variables and management priorities for salt marshes within the National Wildlife Refuge System in the northeastern USA. In general, SDM is a systematic process for decomposing a decision into its essential elements. We first engaged stakeholders in clarifying regional salt marsh decision problems, defining objectives and attributes to evaluate whether objectives are achieved, and developing a pool of alternative management actions for achieving objectives. Through this process, we identified salt marsh attributes that were applicable to monitoring National Wildlife Refuges on a regional scale and that targeted management needs. We then analyzed management decisions within three salt marsh units at Prime Hook National Wildlife Refuge, coastal Delaware, as a case example of prioritizing management alternatives. Values for salt marsh attributes were estimated from 2 years of baseline monitoring data and expert opinion. We used linear value modeling to aggregate multiple attributes into a single performance score for each alternative, constrained optimization to identify alternatives that maximized total management benefits subject to refuge-wide cost constraints, and used graphical analysis to identify the optimal set of alternatives for the refuge. SDM offers an efficient, transparent approach for integrating monitoring into management practice and improving the quality of management decisions.

Understanding the factors that affect salt marsh accretion and elevation gains is of paramount importance if management of these ecosystems is to be successful under increasing synergistic stresses of storm surge, inundation period, and eutrophication. We present the results of salt marsh fucoid algae (ecads) removal experiments on Spartina alterniflora abundance, production and decomposition, and the sedimentary dynamics of two marshes on Cape Cod, Massachusetts. The presence of the thick layer of marsh fucoids had a significant and positive influence on sediment deposition, accretion, and concentration of water column particulates, while it inhibited water flow. Decomposition rates of S. alterniflora in the field were significantly higher under the fucoid macroalgae layer, and, in lab experiments, S. alterniflora seedlings added more leaves when the marsh fucoids were present. In contrast, fucoids caused a significant decrease in S. alterniflora seedlings' survival in the field. We found that marsh fucoids are stable despite not being attached to any substrate, and field surveys revealed a relatively widespread, but not ubiquitous, distribution along outer Cape Cod. Salt marsh fucoid algae directly and substantially contribute to salt marsh sediment elevation gain, yet their potential inhibitory effects on colonizing S. alterniflora may counteract some of their overall contributions to salt marsh persistence and resilience.

The C. botulinum bontE gene that produces the type E toxin was amplified with quantitative PCR from 150 sloughed algal samples (primarily Cladophora species) collected during summer 2012 from 10 Great Lakes beaches in five states; concurrently, 74 sediment and 37 water samples from four sites were also analyzed. The bontE gene concentration in algae was significantly higher than in water and sediment (P < 0.05), suggesting that algal mats provide a better microenvironment for C. botulinum. The bontE gene was detected most frequently in algae at Jeorse Park and Portage Lake Front beaches (Lake Michigan) and Bay City State Recreation Area beach on Saginaw Bay (Lake Huron), where 77, 100, and 83% of these algal samples contained the bontE gene, respectively. The highest concentration of bontE was detected at Bay City (1.98 105 gene copies/ml of algae or 5.21 106 g [dryweight]). This study revealed that the bontE gene is abundant in the Great Lakes but that it has spatial, temporal, and matrix variability. Further, embayed beaches, low wave height, low wind velocity, and greater average water temperature enhance the bontE occurrence.

AN - 1686415870; 25935103 AB - Copper oxide (CuO) nanoparticles (NPs) are widely used, and likely released into the aquatic environment. Both aqueous (i.e., dissolved Cu) and particulate Cu can be taken up by organisms. However, how exposure routes influence the bioavailability and subsequent toxicity of Cu remains largely unknown. Here, we assess the importance of exposure routes (water and sediment) and Cu forms (aqueous and nanoparticulate) on Cu bioavailability and toxicity to the freshwater oligochaete, Lumbriculus variegatus, a head-down deposit-feeder. We characterize the bioaccumulation dynamics of Cu in L. variegatus across a range of exposure concentrations, covering both realistic and worst-case levels of Cu contamination in the environment. Both aqueous Cu (Cu-Aq; administered as Cu(NO3)2) and nanoparticulate Cu (CuO NPs), whether dispersed in artificial moderately hard freshwater or mixed into sediment, were weakly accumulated by L. variegatus. Once incorporated into tissues, Cu elimination was negligible, i.e., elimination rate constants were in general not different from zero for either exposure route or either Cu form. Toxicity was only observed after waterborne exposure to Cu-Aq at very high concentration (305μgL(-1)), where all worms died. There was no relationship between exposure route, Cu form or Cu exposure concentration on either worm survival or growth. Slow feeding rates and low Cu assimilation efficiency (approximately 30%) characterized the uptake of Cu from the sediment for both Cu forms. In nature, L. variegatus is potentially exposed to Cu via both water and sediment. However, sediment progressively becomes the predominant exposure route for Cu in L. variegatus as Cu partitioning to sediment increases. Copyright © 2015 Elsevier B.V. All rights reserved.

PQ0001722642 AB - The Bartlett Springs Fault (BSF), the easternmost branch of the northern San Andreas Fault system, creeps along much of its length. Geodetic data for the BSF are sparse, and surface creep rates are generally poorly constrained. The two existing geodetic slip rate inversions resolve at least one locked patch within the creeping zones. We use the 3-D finite element code FaultMod to conduct dynamic rupture models based on both geodetic inversions, in order to determine the ability of rupture to propagate into the creeping regions, as well as to assess possible magnitudes for BSF ruptures. For both sets of models, we find that the distribution of aseismic creep limits the extent of coseismic rupture, due to the contrast in frictional properties between the locked and creeping regions. Key Points * Rupture on the BSF is confined to locked patches * The BSF can still produce strong earthquakes * Geodetic inversions can be used to inform rupture model setup JF - Geophysical Research Letters AU - Lozos, Julian C AU - Harris, Ruth A AU - Murray, Jessica R AU - Lienkaemper, James J AD - Stanford/USGS, Menlo Park, California, USA.

The role of habitat contamination in the recent decline of the species has rarely been studied and was the main objective of this effort. A wide range of contaminants (115 analytes) was measured in sediments and tissues at 27 sites across a large geographic area of diverse land use. This is the largest dataset of contaminants in habitats and tissues of Pacific lamprey in North America and the first study to compare contaminant bioburden during the larval life stage and the anadromous, adult portion of the life cycle. Bioaccumulation of pesticides, flame retardants, and mercury was observed at many sites. Based on available data, contaminants are accumulating in larval Pacific lamprey at levels that are likely detrimental to organism health and may be contributing to the decline of the species.

We tested assumptions of a population index for endangered Laysan duck (or teal; Anas laysanensis) monitored using mark-resight methods on Laysan Island, Hawai'i. We marked 723 Laysan ducks between 1998 and 2009 and identified seasonal surveys through 2012 that met accuracy and precision criteria for estimating population abundance. Our results provide a 15-y time series of seasonal population estimates at Laysan Island. We found differences in detection among seasons and how observed counts related to population estimates. The highest counts and the strongest relationship between count and population estimates occurred in autumn (September-November). The best autumn surveys yielded population abundance estimates that ranged from 674 (95% CI =619-730) in 2003 to 339 (95% CI =265-413) in 2012. A population decline of 42% was observed between 2010 and 2012 after consecutive storms and Japan's Tohoku earthquake-generated tsunami in 2011. Our results show positive correlations between the seasonal maximum counts and population estimates from the same date, and support the use of standardized bimonthly counts of unmarked birds as a valid index to monitor trends among years within a season at Laysan Island.

In the hatchery, volitional releases (~14 to 15 months post-fertilization) to an adjacent river occurred during October-November. The hatchery release was monitored by using an experimental volitional release that diverted fish to a neighboring raceway. Fish captured during the experimental release (range 361-4,321 volitional migrants) were made up of microjacks and immature parr. Microjacks were found only in the migrant samples, averaged 18% (range 0-52%) of all migrants, and were rarely found in non-migrant samples. In comparison, immature parr were common in both the migrant and non-migrant samples. Microjacks were significantly longer (9%), heavier (36%), and had a greater condition factor (16%) than migrant immature parr (P < 0.01). In addition, they differed significantly (P < 0.01) from non-migrant immature parr; 10% longer, 44% heavier and 14% greater condition factor. In natural streams, microjacks were captured significantly earlier (P < 0.01) than immature parr during the late-summer/fall migration and comprised 9-89% of all fish captured. Microjacks have the potential to contribute to natural spawning populations but can also represent a loss of productivity to hatchery programs or create negative effects by introducing non-native genes to wild populations and should be monitored by fishery managers.

The first half of the 20th century was a time of change on Isle Royale as Caribou (Rangifer tarandus) disappeared, Coyotes (Canis latrans) briefly appeared, Moose (Alces americanus), Grey Wolves (Canis lupus), and Red Foxes (Vulpes vulpes) became established, and the habitat was altered by fire, logging, and over-browsing. Although these changes may have contributed to the demise of the Canada Lynx, our results suggest that over-harvest was a primary cause. Assuming a peak carrying capacity of 75 Canada Lynx and harvest rates comparable to those reported from 1890-1935, a population viability analysis indicated that the island population had a 0% chance of surviving 50 years. The analysis also indicated that, even in the absence of harvest, the population had only a 14% chance of persistence for 250 years. However, when 10 Canada Lynx were added to the modeled population every 10th year, the probability of persistence increased to 100%. Our analyses suggest that the island's Canada Lynx population maintained itself by periodic immigration across an ice bridge; therefore, natural recolonization should be possible. However, the probability of ice-bridge formation has declined from 0.8 in the winter of 1958-59 to 0.1 in 2012-13, likely as a result of climate change. The Isle Royale situation exemplifies another impact of climate change and the possible need to augment populations to mitigate the loss of connectivity.

To test the latter hypothesis and determine whether vaccination against plague with an oral sylvatic plague vaccine (SPV) improved survival, we captured prairie dogs from a C. g. gunnisoni or "montane" population and a C. g. zuniensis or "prairie" population for vaccine efficacy and challenge studies. No differences (P = 0.63) were found in plague susceptibility in non-vaccinated animals between these two populations; however, vaccinates from the prairie population survived plague challenge at significantly higher rates (P < 0.01) than those from the montane population. Upon further analysis, we determined that response to immunization was most likely associated with differences in age, as the prairie group was much younger on average than the montane group. Vaccinates that were juveniles or young adults survived plague challenge at a much higher rate than adults (P < 0.01 and P = 0.02, respectively), but no difference (P = 0.83) was detected in survival rates between control animals of different ages. These results suggest that host susceptibility is probably not related to the assumed greater risk from plague in the C. g. gunnisoni or "montane" populations of Gunnison's prairie dogs, and that SPV could be a useful plague management tool for this species, particularly if targeted at younger cohorts.

This system has been in place since 1980. Although the system has demonstrated its worth and has helped to offset the excessive use of the 1960s and 1970s by raising the average water levels in the aquifer by more than 6 m, the region is still subject to water supply problems. In 2011, several events took place at the local, regional and even international levels which prompted the committee responsible for the use of the transboundary aquifer to tackle the water problem as a result of two events: the Fukushima accident of March 2011 with its radioactive cloud traveling across the globe and passing over Switzerland, and the drought of 2010-2011 which ravaged a large part of Western Europe. The present article examines the effects of these potential problems and raises the issue of the role of the Genevese Aquifer in the provision of drinking water and its artificial recharge as the subjects of a strategic study on water distribution in crisis situations.

Here, we demonstrate the utility of hypothesis testing within the landscape limnology framework using a random forest algorithm on a national-scale, spatially explicit data set, the United States Environmental Protection Agency's 2007 National Lakes Assessment. For 1026 lakes, we tested the relative importance of water quality drivers across spatial scales, the importance of hydrologic connectivity in mediating water quality drivers, and how the importance of both spatial scale and connectivity differ across response variables for five important in-lake water quality metrics (total phosphorus, total nitrogen, dissolved organic carbon, turbidity, and conductivity). By modeling the effect of water quality predictors at different spatial scales, we found that lake-specific characteristics (e.g., depth, sediment area-to-volume ratio) were important for explaining water quality (54-60% variance explained), and that regionalization schemes were much less effective than lake specific metrics (28-39% variance explained). Basin-scale land use and land cover explained between 45-62% of variance, and forest cover and agricultural land uses were among the most important basin-scale predictors. Water quality drivers did not operate independently; in some cases, hydrologic connectivity (the presence of upstream surface water features) mediated the effect of regional-scale drivers. For example, for water quality in lakes with upstream lakes, regional classification schemes were much less effective predictors than lake-specific variables, in contrast to lakes with no upstream lakes or with no surface inflows. At the scale of the continental United States, conductivity was explained by drivers operating at larger spatial scales than for other water quality responses. The current regulatory practice of using regionalization schemes to guide water quality criteria could be improved by consideration of lake-specific characteristics, which were the most important predictors of water quality at the scale of the continental United States. The spatial extent and high quality of contextual data available for this analysis makes this work an unprecedented application of landscape limnology theory to water quality data. Further, the demonstrated importance of lake morphology over other controls on water quality is relevant to both aquatic scientists and managers.

Summer monsoon winds recycle sediment from the lower Indus River and delta northeastward, i.e., downwind and upstream, into the desert. Far-field eolian recycling of Indus sediment is important enough to control sediment provenance at the downwind end of the desert substantially, although the proportion of Indus sediment of various ages varies regionally within the desert; dune sands in the northwestern Thar Desert resemble the late Holocene-Recent Indus delta, requiring short transport and reworking times. On smaller spatial scales (1-10 m) along fluvial channels in the northern Thar Desert, there is also stratigraphic evidence of fluvial and eolian sediment reworking from local rivers. In terms of sediment volume, we estimate that the Thar Desert could be a more substantial sedimentary store than all other known buffer regions in the Indus basin combined.

AN - 1709186899; PQ0001881954 AB - Bat specimens held in natural history museum collections can provide insights into the distribution of species. However, there are several important sources of spatial error associated with natural history specimens that may influence the analysis and mapping of bat species distributions. We analyzed the importance of geographic referencing and error correction in species distribution modeling (SDM) using occurrence records of hoary bats (Lasiurus cinereus). This species is known to migrate long distances and is a species of increasing concern due to fatalities documented at wind energy facilities in North America. We used 3,215 museum occurrence records collected from 1950-2000 for hoary bats in North America. We compared SDM performance using five approaches: generalized linear models, multivariate adaptive regression splines, boosted regression trees, random forest, and maximum entropy models. We evaluated results using three SDM performance metrics (AUC, sensitivity, and specificity) and two data sets: one comprised of the original occurrence data, and a second data set consisting of these same records after the locations were adjusted to correct for identifiable spatial errors. The increase in precision improved the mean estimated spatial error associated with hoary bat records from 5.11 km to 1.58 km, and this reduction in error resulted in a slight increase in all three SDM performance metrics. These results provide insights into the importance of geographic referencing and the value of correcting spatial errors in modeling the distribution of a wide-ranging bat species. We conclude that the considerable time and effort invested in carefully increasing the precision of the occurrence locations in this data set was not worth the marginal gains in improved SDM performance, and it seems likely that gains would be similar for other bat species that range across large areas of the continent, migrate, and are habitat generalists.

For example, at night bats use vision to orient across landscapes, avoid large obstacles, and locate roosts. Although lacking sharp visual acuity, the eyes of bats evolved to function at very low levels of illumination. Recent evidence based on genetics, immunohistochemistry, and laboratory behavioral trials indicated that many bats can see ultraviolet light (UV), at least at illumination levels similar to or brighter than those before twilight. Despite this growing evidence for potentially widespread UV vision in bats, the prevalence of UV vision among bats remains unknown and has not been studied outside of the laboratory. We used a Y-maze to test whether wild-caught bats could see reflected UV light and whether such UV vision functions at the dim lighting conditions typically experienced by night-flying bats. Seven insectivorous species of bats, representing five genera and three families, showed a statistically significant 'escape-toward-the-light' behavior when placed in the Y-maze. Our results provide compelling evidence of widespread dim-light UV vision in bats.

The source of these solutes is unknown; however, an understanding of the geochemical sources and processes controlling their presence in groundwater in the Mud Lake area is needed to better understand the geochemical sources and processes controlling the water quality of groundwater at the Idaho National Laboratory. The geochemical sources and processes controlling the water quality of groundwater in the Mud Lake area were determined by investigating the geology, hydrology, land use, and groundwater geochemistry in the Mud Lake area, proposing sources for solutes, and testing the proposed sources through geochemical modeling with PHREEQC. Modeling indicated that sources of water to the eastern Snake River Plain aquifer were groundwater from the Beaverhead Mountains and the Camas Creek drainage basin; surface water from Medicine Lodge and Camas Creeks, Mud Lake, and irrigation water; and upward flow of geothermal water from beneath the aquifer. Mixing of groundwater with surface water or other groundwater occurred throughout the aquifer. Carbonate reactions, silicate weathering, and dissolution of evaporite minerals and fertilizer explain most of the changes in chemistry in the aquifer. Redox reactions, cation exchange, and evaporation were locally important. The source of large concentrations of chloride, sodium, sulfate, and calcium was evaporite deposits in the unsaturated zone associated with Pleistocene Lake Terreton. Large amounts of chloride, sodium, sulfate, and calcium are added to groundwater from irrigation water infiltrating through lake bed sediments containing evaporite deposits and the resultant dissolution of gypsum, halite, sylvite, and bischofite.

Understanding the behavioral ecology of Black and White Tegus could aid in management and control plans. Black and White Tegus are seasonally active and brumate during the winter in their native range, but brumation behavior is largely unstudied in either the native or the invasive range. We describe the first observations of Black and White Tegu brumation in southeastern Florida after monitoring 5 free-ranging, adult male Black and White Tegus through an inactive season using radiotelemetry and automated cameras. Duration of brumation averaged 137 days, beginning in September and ending by February. One of the 5 Black and White Tegus emerged to bask regularly during brumation, which to our knowledge represents the first documented instance of a free-ranging Black and White Tegu basking during brumation. These preliminary findings provide a basis for future research of brumation behavior.

Although the portal is closed during floods, mean flows and turbidity of portal waters are generally greater than in Esopus Creek above their confluence. These conditions could potentially affect local fish assemblages, yet such effects have not been assessed in this highly regulated stream. We studied water quality, hydrology, temperature, and fish assemblages at 18 sites in the Upper Esopus Creek during 2009-2011 to characterize the effects of the portal input on resident-fish assemblages and to document the status of the fishery resource. In general, fish-community richness increased by 2-3 species at mainstem sites near the portal, and median density and biomass of fish communities at sites downstream of the portal were significantly lower than they were at sites upstream of the portal. Median densities of Salmo trutta (Brown Trout) and all trout species were significantly lower than at mainstem sites downstream from the portal-25.1 fish/0.1 ha and 148.9 fish/0.1 ha, respectively-than at mainstem sites upstream from the portal-68.8 fish/0.1 ha and 357.7 fish/0.1 ha, respectively-yet median biomass for Brown Trout and all trout did not differ between sites from both reaches. The median density of young-of-year Brown Trout at downstream sites (9.3 fish/0.1 ha) was significantly lower than at upstream sites (33.9 fish/0.1 ha). Waters from the portal appeared to adversely affect the density and biomass of young-of-year Brown Trout, but lower temperatures and increased flows also improved habitat quality for mature trout at downstream sites during summer. These findings, and those from companion studies, indicate that moderately turbid waters from the portal had few if any adverse impacts on trout populations and overall fish communities in the Upper Esopus Creek during this study.

Distributions of parameter values across multiple temporal and spatial scales, commonly referred to as regimes, add greater context and interpretability to point measurements. Although uncommon among monitoring programmes, continuous water quality data collected at high frequency (e.g. hourly) can characterize waterbody health more accurately than infrequent point measurements. We used multivariate analysis to describe water quality regimes based on hourly measurements of dissolved oxygen, pH, specific conductance and water temperature from three divergent stream types in Southeast Alaska national parks. We also assessed whether less frequent measurements drawn from the original hourly data set resulted in similar water quality regime descriptions. The monthly means and standard deviations of the four water quality parameters created ordinations with interpretable, stream-specific environmental gradients. Procrustean analysis revealed that ordination results were strikingly similar across all temporal monitoring frequencies. Univariate medians and distributions of weekly, twice monthly and monthly measurements were similar across all parameters, but hourly monitoring was necessary to accurately characterize extreme values. These analyses demonstrated the ability of commonly collected water quality parameters to define unique physical-chemical properties across regional stream types and present scientists with common analytical tools to determine appropriate monitoring scales for accurately characterizing water quality regimes.

There is evidence that both accumulation and toxicity of metal NPs to sediment-dwellers increase with decreasing particle size, although NP size does not always predict effects. In contrast, not much is known about the influence of particle shape on bioaccumulation and toxicity. Here, we examined the influence of copper oxide (CuO) NP shape (rods, spheres, and platelets) on their bioaccumulation kinetics and toxicity to the sediment-dwelling gastropod, Potamopyrgus antipodarum. The influence of Cu added as CuCl2 (i.e., aqueous Cu treatment) was also examined. Exposure to sediment mixed with aqueous Cu or with different-shaped CuO NPs at an average measured exposure concentration of 207μg Cu per g dry weight sediment for 14 days did not significantly affect snail mortality. However, growth decreased for snails exposed to sediment amended with CuO NP spheres and platelets. P. antipodarum accumulated Cu from all Cu forms/shapes in significant amounts compared to control snails. In addition, once accumulated, Cu was efficiently retained (i.e., elimination rate constants were generally not significantly different from zero). Consequently, snails are likely to concentrate Cu over time, from both aqueous and NP sources, resulting in a high potential for toxicity. Copyright © 2015 Elsevier B.V. All rights reserved.

AN - 1671210103; 25795925 AB - Lead is a prominent and highly toxic contaminant with important impacts to wildlife. To understand the degree to which wildlife populations are chronically exposed, we quantified lead levels within American black vultures (Coragyps atratus; BLVU) and turkey vultures (Cathartes aura; TUVU), two species that are useful as environmental sentinels in eastern North America. Every individual sampled (n=108) had bone lead levels indicative of chronic exposure to anthropogenic lead (BLVU: x¯=36.99 ± 55.21 mg Pb/kg tissue (±SD); TUVU: x¯=23.02 ± 18.77 mg/kg). Only a few showed evidence of recent lead exposure (BLVU liver: x¯=0.78 ± 0.93 mg/kg; TUVU liver: x¯=0.55 ± 0.34 mg/kg). Isotopic ratios suggested multiple potential sources of lead including ammunition, gasoline, coal-fired power plants, and zinc smelting. Black and turkey vultures range across eastern North America, from Quebec to Florida and individuals may traverse thousands of kilometers annually. The extent to which vultures are exposed suggests that anthropogenic lead permeates eastern North American ecosystems to a previously unrecognized degree. Discovery of an epidemic of chronic lead exposure in such widespread and common species and the failure of soft-tissue sampling to diagnose this pattern has dramatic implications for understanding modern wildlife and human health concerns.

Genetic differentiation should thus occur over relatively small vertical distances, particularly along the upper continental slope (200-1000 m) where oceanography varies greatly over small differences in depth. To test whether genetic differentiation within deepwater octocorals is greater over vertical rather than geographical distances, Callogorgia delta was targeted. This species commonly occurs throughout the northern Gulf of Mexico at depths ranging from 400 to 900 m. We found significant genetic differentiation (FST = 0.042) across seven sites spanning 400 km of distance and 400 m of depth. A pattern of isolation by depth emerged, but geographical distance between sites may further limit gene flow. Water mass boundaries may serve to isolate populations across depth; however, adaptive divergence with depth is also a possible scenario. Microsatellite markers also revealed significant genetic differentiation (FST = 0.434) between C. delta and a closely related species, Callogorgia americana, demonstrating the utility of microsatellites in species delimitation of octocorals. Results provided support for the depth-differentiation hypothesis, strengthening the notion that factors covarying with depth serve as isolation mechanisms in deep-sea populations.

PQ0001588455 AB - The fault history of the Mill Creek strand of the San Andreas fault (SAF) in the San Gorgonio Pass region, along with the reconstructed geomorphology surrounding this fault strand, reveals the important role of the left-lateral Pinto Mountain fault in the regional fault strand switching. The Mill Creek strand has 7.1-8.7 km total slip. Following this displacement, the Pinto Mountain fault offset the Mill Creek strand 1-1.25 km, as SAF slip transferred to the San Bernardino, Banning, and Garnet Hill strands. An alluvial complex within the Mission Creek watershed can be linked to palinspastic reconstruction of drainage segments to constrain slip history of the Mill Creek strand. We investigated surface remnants through detailed geologic mapping, morphometric and stratigraphic analysis, geochronology, and pedogenic analysis. The degree of soil development constrains the duration of surface stability when correlated to other regional, independently dated pedons. This correlation indicates that the oldest surfaces are significantly older than 500 ka. Luminescence dates of 106 ka and 95 ka from (respectively) 5 and 4 m beneath a younger fan surface are consistent with age estimates based on soil-profile development. Offset of the Mill Creek strand by the Pinto Mountain fault suggests a short-term slip rate of similar to 10-12.5 mm/yr for the Pinto Mountain fault, and a lower long-term slip rate. Uplift of the Yucaipa Ridge block during the period of Mill Creek strand activity is consistent with thermochronologic modeled uplift estimates.

The road is a major conduit for approximately 500,000 visitors to the park each year and is also the only access for several lodges located in Kantishna (mile 92). The park, and therefore the road, is a major economic engine for the region. Most visitation is during summer months, which is also when landslides are likely because seasonally-frozen ground is thawed. Much of the road traverses areas of permafrost, which is regionally known to be thawing; this trend may be contributing to greater frequency of events. The Denali Park Road has experienced numerous landslides through history. The most dramatic occurred in October 2013 when a 180-m-long, 35-m-wide debris slide blocked the road near mile 38. Blocks of permafrost-frozen, unconsolidated debris up to 5 m thick slid on slippery, unfrozen clay. Fortunately, this event occurred after the road was closed for the season. If it had occurred during visitor season, it may have resulted in fatalities/injuries as well as economic losses for the entire region. Many less dramatic events have blocked traffic, undermined road surfaces, and caused damage to vehicles. Numerous individual slides are monitored along the road and this event could have seriously endangered visitor safety; therefore a risk analysis must be completed to identify the highest risks so they can be properly mitigated before future events occur. National Park Service (NPS) staff are partnering with the Federal Highway Administration (FHWA) to complete a comprehensive risk analysis of the road. The risk analysis will include five parts: (1) inventory maps and linked database that illustrate spatial/temporal distribution of geohazards, their relative activity, and geomorphic attributes; (2) alpha/beta testing of the new Unstable Slope Management Program rating criteria; (3) susceptibility maps and linked database that illustrate spatial distribution of geohazards in an area and their probability of occurrence; and (4) geohazard risk maps and linked database that illustrate where landslides and other geohazards may initiate, and probability and consequences of occurrence. The NPS and FHWA will use results to mitigate those areas identified in the highest risk categories.

Evidence of extreme pre-historical floods preserved in the geologic record and of long-term landscape stability can be used to estimate the flood hazard. A study of the Kern River in southern California was undertaken by the Bureau of Reclamation for the U.S. Army Corps of Engineers as a pilot study to illustrate the advantages of incorporating paleoflood data in hydrologic hazard assessment. Five study reaches along the Kern River were examined and data from 18 stratigraphic sites including soil stratigraphic information and radiocarbon ages were collected to document the sedimentological characteristics of the fluvial deposits. Soil properties and radiocarbon ages on detrital charcoal samples recovered from discrete stratigraphic units provide age information on the timing of deposition and provide a measure of landscape stability. A two-dimensional depth-averaged hydraulic model was used to make peak discharge estimates for paleofloods preserved in the stratigraphic record and for the non-exceedance bounds. These discharge estimates were made using topographic information derived from photogrammetry and LiDAR data. The hydraulic model was calibrated to high water marks documented for several extreme historical floods. Hydraulic model results were cross referenced with the stratigraphic data to allow estimates of peak discharge to be refined given changes in water depth, velocity, shear stress, and flow patterns over a range of channel roughness. The stratigraphic record preserves evidence for at least two paleofloods. The magnitude of each paleoflood appears similar to or slightly smaller than the largest historical floods. Hydraulic model estimates suggest a range in discharge from about 115,000 ft (super 3) /s to about 225,000 ft (super 3) /s. Radiocarbon ages on correlative deposits indicate that these paleofloods occurred between 1025 and 1425 years ago. In addition to the evidence of paleofloods, there is also evidence of longer term stability provided by a soil formed on bedrock that provides the basis for a non-exceedance bound. Hydraulic model estimates of the peak associated with this non-exceedance bound suggest a range in discharge from 265,000 ft (super 3) /s to about 300,000 ft3/s.

The Black Nose Pumice (BNP), informally named for caldera rim exposures by Black Nose peak, is the product of the most explosive and voluminous silicic eruptions of Aniakchak known prior to the approximately 3430 (super 14) C yr B.P. Aniakchak II caldera-forming event. We apply the name Black Nose Pumice to Plinian fall deposits (total thickness > or =25 m) and intraplinian ignimbrite north of The Gates and elsewhere near the caldera rim. Lower BNP consists of highly inflated crystal-poor buff-colored rhyodacite pumice ( approximately 69% SiO (sub 2) ). Postglacial lava under, and ignimbrite within the BNP below the caldera rim north of The Gates are compositionally identical to lower BNP fall. The upper BNP fall consists of brown dacite pumice ( approximately 67.5% SiO (sub 2) ) with greater phenocryst content than lower BNP. Basal upper BNP fall is partly welded and forms a dark-gray band in caldera rim exposures. A northeast flank postglacial dacite lava flow is similar in composition to upper BNP. Both lower and upper units are less evolved than Aniakchak II rhyodacite, which also is distinctive in carrying hornblende phenocrysts. The age of the lower BNP is constrained by tephrochronology for a 45-cm-thick pumice bed approximately 40 km southeast of the caldera at Cabin Bluff near Aniakchak Bay. New electron microprobe analyses of glass, magnetite, and ilmenite in pumice from the caldera rim and Cabin Bluff show that this bed correlates with lower BNP. Fe-Ti oxides yield preeruption temperatures of approximately 940-950 degrees C and fO (sub 2) approximately Ni-NiO for both localities. Peat from beneath the Cabin Bluff pumice bed gave a radiocarbon age of 7,350+ or -70 (super 14) C yr B.P., whereas soil beneath the same bed 600 m distant gave 6,760+ or -60 (super 14) C yr B.P. (VanderHoek 2009 Ph.D. thesis), leading us to suggest an age of approximately 7,000 (super 14) C yr B.P. for the lower Black Nose Pumice. Pollen study at Cabin Bluff by R.E. Nelson (in VanderHoek 2009) indicates grasses dominated in revegetation following the BNP eruption, with lesser sage, birch, and sedges, in contrast to the modern Pacific coast assemblage dominated by alder and fern. The BNP eruption strongly depressed biological productivity of the region and appears to have caused a long-term hiatus in human occupation of the central Alaska Peninsula.

Various sources document belemnites from Arctic, southwest, south central and southeast Alaska. However, in many cases details are lacking, specimens are not identified, and revisions in systematics and dating have occurred. We are engaged in a project to identify all published references to Alaska belemnites; to locate and identify Alaskan specimens in museum collections; compile data from USGS evaluations and reports; and identify recently collected specimens. The focus of this report is the belemnite fauna of the Tuxedni Group (Middle Jurassic, Bajocian) exposed near Fossil Point, Tuxedni Bay, Alaska Peninsula, in Lake Clark National Park. Specimens of invertebrate macrofossils were collected in August 2014 as part of a Park Service fossil inventory of Fossil Point. The fossil assemblage consists of bivalves, ammonites, and belemnites. Five belemnite specimens were collected from float of the upper 25 meters of the Red Glacier Formation and brought to Anchorage for photography and preparation. Four were photographed in situ in the Red Glacier Formation and Fitz Creek Siltstone but not collected. Those collected included a phragmocone with an oval cross section. The size and shape were suggestive of Megateuthis, but without a rostrum this cannot be confirmed. Another specimen consisting of two partial rostra in matrix showed features suggestive of Cylindroteuthis, but since the apices were missing, this also is only a tentative diagnosis. The most complete rostrum collected has been identified as Pachyteuthis, possibly of a species not previously documented. Evaluation of this specimen is still in progress. Megateuthis, Gastrobelus, Cylindroteuthis and Pachyteuthis have been documented in museum collections from Jurassic formations of the Alaska Peninsula but no details on localities are stated and the specimens are not figured (Stevens, G. R. 1965). The paleogeography of belemnites reflects their migration patterns and locations of terranes in the Jurassic. Therefore, further characterization of this group in Lake Clark National Park may contribute to our understanding of the history of the Peninsular terrane in the early Middle Jurassic.

Element distribution in soils and sediments is influenced by geochemical cycling and anthropogenic factors. Single element maps are a useful tool to identify anomalous elemental concentrations, whereas multivariate analysis facilitates interpretation of geochemical patterns and their links to local and regional geology. We use soil data from a regional geochemical soil transect and statewide legacy sediment data to evaluate geochemical patterns across Alaska. The resultant maps highlight anomalous element concentrations that correlate with geology. Some elements reflect the primary bedrock, whereas other elements reflect secondary surficial geology and soil development. For example, geochemical signatures of soils and sediments reflect the presence of ultramafic rocks and enrichments of U, Th, and REE associated with alkaline igneous rocks. Comparison of the elemental content between soil horizons helps distinguish geogenic enrichment in surface soil from enrichment due to elemental cycling or anthropogenic factors. Comparison of magnetic and nonmagnetic heavy mineral concentrates helps determine what minerals occur with different types of mineralization, and also helps to constrain the relative mobility of different elements in the surface environment. Futhermore, watershed-based analyses of sediment samples identify hydrologic subbasins where sediment samples on average have high, moderate, or low mean element concentrations. Watershed-based maps, when combined with alteration mapping derived from Landsat 8 Operational Land Imager data, show areas where rocks may be altered and weathered, possibly less competent, prone to enhanced weathering, and possible source areas for downslope soils and sediments. The suite of techniques applied here helps evaluate the geologic sources of geochemical anomalies across the state.

Incorporating the most recent primary literature, print and media publications were developed to be accessible, readable and captivating to a general public audience, assuming a baseline level of scientific literacy. Research was conducted through a GSA Geocorps Internship at Oregon Caves National Monument (ORCA), in collaboration with ORCA Chief Naturalist and Head of Resource Management John Roth, and illustrator and geologist Audrey Ledford, as well as personal communication with Drs. Nan Lindsley-Griffin and John Griffin, primary authors on the Eastern Klamath terranes. The project focuses specifically on documenting evidence for the geologic and tectonic evolution of the oldest terrane belt in the KMP, the Eastern Klamaths. Recent publication and classification of Neoproterozoic (Vendian) cyclomedusoid fossils from the Antelope Mountain Quartzite of the Yreka terrane (Griffin et al. 2006) unifies the work as a narrative thread. As a public education outreach project, the ultimate goal of the work is to address a critical gap in public awareness and understanding of contemporary geoscience research, especially as related to recent reinterpretations of the driving forces behind plate tectonics, mantle dynamics, and terrane accretionary processes. A major emphasis of the piece is in highlighting the many unsolved mysteries of the Eastern Klamath terranes and assembly of the Western Cordillera as a whole.

The locality contains one of the most productive marine invertebrate fossil sites known in Alaska. The Middle Jurassic Tuxedni Group contains exceptionally rich and diverse megainvertebrate faunas: ammonites, bivalves, and belemnites. The most obvious fossils are the large and abundant inoceramid bivalves. A field study was conducted during August 2014 by the National Park Service evaluating the paleontological and stratigraphical setting of strata exposed at Fossil Point. A large number of fossils were collected and stratigraphic control for the fossils was completed by measuring stratigraphic sections. The bivalve fossils of Tuxedni Bay were first described and illustrated by Eichwald (1871). Four new inoceramid species (Inoceramus ambiguus, I. porrectus, I. eximius, and I. lucifer) were established by Eichwald, and there has been subsequent debate by paleontologists as whether they are valid or merely represent ecological variants belonging to one or two species. During this study, we collected four distinct species that we believe represent the four species identified by Eichwald. Little has been reported about the Pleuromya and Pholadomya bivalves that are abundant in all the strata at the site. We collected four distinct species of the genus Pleuromya that include P. aleutica, P. dilitata, and P. aldaini(?). One species yet to be identified is similar to P. aleutica, but has a less pronounced posterior enlargement. We found one specimen of Pholadomya sp. Classification of the common belemnite fossils of the Tuxedni Group is lacking. Classifying the few belemnites collected may hold important clues to the biogeography and migration patterns of this common fossil, and is presented by Schraer et al. in this session. Fossil Point is located in a remote and difficult to access location. The fossil collection housed at the NPS Alaska Region Curatorial Center will be available to the public and park staff for research and education. To promote research in the park and better educate park visitors and staff, three dimensional models of the fossils are being created and shared with scientists and on the web. These 3D models are presented by Wood et al. in the Ray Troll fossil art session.

We determined whole-fish total mercury (Hg) concentrations of 25 male and 25 female adult burbot Lota lota captured in Lake Erie during summer 2011 and of 14 male and 18 female adult burbot captured in Great Slave Lake (Northwest Territories, Canada) during winter 2013. On average, females had 22 % greater Hg concentrations than males. This difference was probably not due to a greater feeding rate by females because results from previous studies based on polychlorinated biphenyl determinations of these same burbot indicated that males fed at a substantially greater rate than females. Based on our determinations of Hg concentrations in the gonads and somatic tissue of 5 ripe females and 5 ripe males, this difference was not attributable to changes in Hg concentration immediately after spawning due to the release of gametes. Furthermore, bioenergetics modeling results from previous studies indicated that growth dilution would not explain any portion of this observed difference in Hg concentrations between the sexes. We therefore conclude that this difference was most likely due to a substantially faster rate of Hg elimination by males compared with females. Male burbot exhibit among the greatest gonadosomatic indices (GSIs) of all male fishes, with their testes accounting for between 10 and 15 % of their body weight when the fish are in ripe condition. Androgens have been linked to enhanced Hg-elimination rates in other vertebrates. If androgen production is positively related to GSI, then male burbot would be expected to have among the greatest androgen levels of all fishes. Thus, we hypothesize that male burbot eliminate Hg from their bodies faster than most other male fishes and that this explains the greater Hg concentration in females compared with males.

We tested stream water and sediment over 25 days and downstream for 7.6 km for the following: fecal indicator bacteria (FIB), the fecal indicator chemicals cholesterol and coprostanol, 20 genes for zoonotic and swine-specific bacterial pathogens by presence/absence PCR for viable cells, one swine-specific Escherichia coli toxin gene (STII gene) by quantitative PCR (qPCR), and nine human and animal viruses by qPCR or reverse transcription-qPCR. Twelve days postspill, and 4.2 km downstream, water concentrations of FIB, cholesterol, and coprostanol were 1 to 2 orders of magnitude greater than those detected before, or above, the spill, and genes indicating viable zoonotic or swine-infectious Escherichia coli were detected in water or sediment. STII gene levels increased from undetectable before or above the spill to 105 copies/100 ml of water 12 days postspill. Thirteen of 14 water (8/9 sediment) samples had viable STII-carrying cells postspill. Eighteen days postspill, porcine adenovirus and teschovirus were detected 5.6 km downstream. FIB concentrations (per gram [wetweight]) in sediment were greater than in water, and sediment was a continuous reservoir of genes and chemicals postspill. Constituent concentrations were much lower, and detections less frequent, in a runoff event (200 days postspill) following manure application, although the swine-associated STII and stx2e genes were detected. Manure spills are an underappreciated pathway for livestock-derived contaminants to enter streams, with persistent environmental outcomes and the potential for human and veterinary health consequences.

The area is extensively faulted, with water-level differences exceeding 60 m across parts of the Rialto-Colton Fault separating the Rialto-Colton and Chino groundwater subbasins. Coupled well-bore flow and depth-dependent water-quality data show decreases in well yield and changes in water chemistry and isotopic composition, reflecting changing aquifer properties and groundwater recharge sources with depth. Perchlorate movement through some wells under unpumped conditions from shallower to deeper layers underlying mapped plumes was as high as 13 kg/year. Water-level maps suggest potential groundwater movement across the Rialto-Colton Fault through an overlying perched aquifer. Upward flow through a well in the Chino subbasin near the Rialto-Colton Fault suggests potential groundwater movement across the fault through permeable layers within partly consolidated deposits at depth. Although potentially important locally, movement of groundwater from the Rialto-Colton subbasin has not resulted in widespread occurrence of perchlorate within the Chino subbasin. Nitrate and perchlorate concentrations at the water table, associated with legacy agricultural fertilizer use, may be underestimated by data from long-screened wells that mix water from different depths within the aquifer.Original Abstract: Le perchlorate d'origine militaire, industrielle ou agricole est present au sein de l'aquifere alluvial du sous-bassin souterrain de Rialto-Colton situe a 80 km a l'est de Los Angeles (Etats-Unis d'Ameriques). Ce secteur est fortement faille et presente des differences piezometriques depassant 60 m de part et d'autre de la faille de Rialto-Colton separant les sous-bassins souterrains de Rialto-Colton et de Chino. Les donnees combinees de flux de puits de forage et de qualite des eaux a diverses profondeurs montrent une diminution du rendement des puits et des changements de la composition chimique et isotopique des eaux, refletant ainsi un changement des proprietes aquiferes et de l'origine de la recharge avec la profondeur. Les flux de perchlorate, au travers de quelques forages sous des conditions de sous-exploitation, des couches de surface vers les niveaux plus profonds situes sous le panache identifie peuvent atteindre 13 kg/an. La carte piezometrique indique des flux d'eau potentiels le long de la faille de Rialto-Colton au travers des aquiferes perches sus-jacents. Les flux ascendants au travers d'un puits du sous-bassin de Chino, proche de la faille de Rialto-Colton, suggerent de possibles mouvements d'eau au travers de la faille et au sein de couches permeables ayant, en profondeur, des depots partiellement consolides.

If we prioritize savanna restoration, we should ask how savanna animal communities differ from communities in related open habitats and forests. We documented distribution of amphibian and reptile species across an open-savanna-forest gradient in the Midwest U.S. to determine how fire history and habitat structure affected herpetofaunal community composition. The transition from open habitats to forests was a transition from higher reptile abundance to higher amphibian abundance and the intermediate savanna landscape supported the most species overall. These differences warn against assuming that amphibian and reptile communities will have similar ecological responses to habitat structure. Richness and abundance also often responded in opposite directions to some habitat characteristics, such as cover of bare ground or litter. Herpetofaunal community species composition changed along a fire gradient from infrequent and recent fires to frequent but less recent fires. Nearby (200-m) wetland cover was relatively unimportant in predicting overall herpetofaunal community composition while fire history and fire-related canopy and ground cover were more important predictors of composition, diversity, and abundance. Increased developed cover was negatively related to richness and abundance. This indicates the importance of fire history and fire related landscape characteristics, and the negative effects of development, in shaping the upland herpetofaunal community along the native grassland-forest continuum.

The toxicity of CPN over a 7-day exposure period was investigated in American kestrels (Falco sparverius) fed either rat tissue mechanically-amended with CPN, tissue from rats fed Rozol super( registered ) bait (biologically-incorporated CPN), or control diets (tissue from untreated rats or commercial bird of prey diet) ad libitum. Nominal CPN concentrations in the formulated diets were 0.15, 0.75 and 1.5 mu g/g food wet weight, and measured concentrations averaged 94 % of target values. Kestrel food consumption was similar among groups and body weight varied by less than 6 %. Overt signs of intoxication, liver CPN residues, and changes in prothrombin time (PT), Russell's viper venom time (RVVT) and hematocrit, were generally dose-dependent. Histological evidence of hemorrhage was present at all CPN dose levels, and most frequently observed in pectoral muscle and heart. There were no apparent differences in toxicity between mechanically-amended and biologically-incorporated CPN diet formulations. Dietary-based toxicity reference values at which clotting times were prolonged in 50 % of the kestrels were 79.2 mu g CPN consumed/kg body weight-day for PT and 39.1 mu g/kg body weight-day for RVVT. Based upon daily food consumption of kestrels and previously reported CPN concentrations found in small mammals following field baiting trials, these toxicity reference values might be exceeded by free-ranging raptors consuming such exposed prey. Tissue-based toxicity reference values for coagulopathy in 50 % of exposed birds were 0.107 mu g CPN/g liver wet weight for PT and 0.076 mu g/g liver for RVVT, and are below the range of residue levels reported in raptor mortality incidents attributed to CPN exposure. Sublethal responses associated with exposure to environmentally realistic concentrations of CPN could compromise survival of free-ranging raptors, and should be considered in weighing the costs and benefits of anticoagulant rodenticide use in pest control and eradication programs.

However, because of high variability on short (i.e., diurnal, seasonal, and annual) timescales as well as the recency of a comprehensive instrumental record, it is difficult to detect or provide evidence for long-term, site-specific trends in ocean temperature. Here we analyze five in situ datasets from Florida Keys coral reef habitats, including historic measurements taken by lighthouse keepers, to provide three independent lines of evidence supporting approximately 0.8 degree C of warming in sea surface temperature (SST) over the last century. Results indicate that the warming observed in the records between 1878 and 2012 can be fully accounted for by the warming observed in recent decades (from 1975 to 2007), documented using in situ thermographs on a mid-shore patch reef. The magnitude of warming revealed here is similar to that found in other SST datasets from the region and to that observed in global mean surface temperature. The geologic context and significance of recent ocean warming to coral growth and population dynamics are discussed, as is the future prognosis for the Florida reef tract.

Lakes Michigan and Huron, which are undergoing oligotrophication after reduction of phosphorus loading, invasion by dreissenid mussels and variation in climate, provide an opportunity to conduct large-scale evaluation of the relative importance of these changes for lake productivity. We used remote sensing, field data and an information-theoretic approach to identify factors that showed statistical relationships with observed changes in chlorophyll a (chla) and primary production (PP). 2. Spring phosphorus (TP), annual mean chla and PP have all declined significantly in both lakes since the late 1990s. Additionally, monthly mean values of chla have decreased in many but not all months, indicating altered seasonal patterns. The most striking change has been the decrease in chla concentration during the spring bloom. 3. Mean chlorophyll a concentration was 17% higher in Lake Michigan than in Lake Huron, and total production for 2008 in Lake Michigan (9.5 tg year super(-1)) was 10% greater than in Lake Huron (7.8 tg year super(-1)), even though Lake Michigan is slightly smaller (by 3%) than Lake Huron. Differences between the lakes in the early 1970s evidently persisted to 2008. 4. Invasive mussels influenced temporal trends in spring chla and annual primary production. However, TP had a greater effect on chla and primary production than did the mussels, and TP varied independently from them. Two climatic variables (precipitation and air temperature in the basins) influenced annual chla and annual PP, while the extent of ice cover influenced TP but not chla or primary production. Our results demonstrate that observed temporal patterns in chla and PP are the result of complex interactions of P, climate and invasive mussels.

The Yela River and the Sapwalap River, Federated States of Micronesia, contain a natural soil resource gradient defined by total phosphorus (P) density ranging from 0.05 to 0.42 mg cm super(-3) in different hydrogeomorphic settings. We used this fertility gradient to test the hypothesis that edaphic conditions constrain mangrove productivity through differential allocation of biomass to belowground roots. We removed sequential cores and implanted root ingrowth bags to measure in situ biomass and productivity, respectively. Belowground root biomass values ranged among sites from 0.448 plus or minus 0.096 to 2.641 plus or minus 0.534 kg m super(-2). Root productivity (roots less than or equal to 20 mm) did not vary significantly along the gradient (P = 0.3355) or with P fertilization after 6 months (P = 0.2968). Fine root productivity (roots less than or equal to 2 mm), however, did vary significantly among sites (P = 0.0363) and ranged from 45.88 plus or minus 21.37 to 118.66 plus or minus 38.05 g m super(-2) year super(-1). The distribution of total standing root biomass and fine root productivity followed patterns of N:P ratios as hypothesized, with larger root mass generally associated with lower relative P concentrations. Many of the processes of nutrient acquisition reported from nutrient-limited mangrove forests may also occur in forests of greater biomass and productivity when growing along soil nutrient gradients.

Previous experimental studies of WNV in ducks either have challenged a small number of ducks with WNV or have tested domesticated ducks. To determine susceptibility and immune response, we challenged 7-wk-old Wood Ducks (Aix sponsa) with a 1999 American Crow (Corvus brachyrhynchos) isolate of WNV. Wood Ducks were susceptible to infection with the virus, and, although clinical signs or mortality were not observed, microscopic lesions were noted, particularly in the heart and brain. West Nile virus viremia peaked on day 2 postinfection (pi) at 10 super(4.54) plaque-forming units (PFU) of virus/mL serum and WNV was shed orally (between 10 super(2) and 10 super(2.9) PFU per swab) and cloacally. Specific anti-WNV antibody response was rapid, with anti-WNV IgM detected on day 3 pi followed on day 5 pi by anti-WNV IgG. Neutralizing antibodies were detected by plaque-reduction neutralization assay in one duck on day 4 pi, and in all sampled ducks on day 5. These results indicate that Wood Ducks are susceptible to WNV, but it is unlikely that significant WNV mortality events occur in Wood Ducks or that they play a significant role in transmission. However, WNV viremia was sufficient, in theory, to infect mosquitoes, and oral and cloacal shedding of the virus may increase the risk of infection to other waterbirds.

Any errors in this value can compromise amplitude estimates in otherwise high-quality data. To estimate an upper bound in the uncertainty of the midband sensitivity for modern broadband instruments, we compare daily microseism (4- to 8-s period) amplitude ratios between the vertical components of colocated broadband sensors across the IRIS/USGS (network code IU) seismic network. We find that the mean of the 145,972 daily ratios used between 2002 and 2013 is 0.9895 with a standard deviation of 0.0231. This suggests that the ratio between instruments shows a small bias and considerable scatter. We also find that these ratios follow a standard normal distribution (R super(2)=0.95442), which suggests that the midband sensitivity of an instrument has an error of no greater than plus or minus 6 % with a 99 % confidence interval. This gives an upper bound on the precision to which we know the sensitivity of a fielded instrument.

Located within the Colorado Mineral Belt, USA, Henderson is the second largest Climax-type Mo deposit in the world, and is therefore an excellent location to investigate magmatic processes leading to Climax-type Mo mineralization. We combine an extensive dataset of major element, volatile, and trace element abundances in quartz-hosted melt inclusions and pumice matrix glass with major element geochemistry from phenocrysts to reconstruct the pre-eruptive conditions and the source and evolution of metals within the magma. Melt inclusions are slightly peraluminous topaz rhyolitic in composition and are volatile-charged ( less than or equal to 6wt % H sub(2)O, less than or equal to 600ppm CO sub(2), 0.3-1.0wt % F, 2300-3500ppm Cl) and metal-rich (7-24ppm Mo, 4-14ppm W, 21-52ppm Pb, 28-2700ppm Zn, <0.1-29ppm Cu, 0.3-1.8ppm Bi, 40-760ppb Ag, 690-1400ppm Mn). Melt inclusion and pumice matrix glass chemistry reveal that the Hideaway Park magma evolved by large degrees of fractional crystallization ( less than or equal to 60-70%) during quartz crystallization and melt inclusion entrapment at pressures of less than or equal to 300MPa ( less than or equal to 8km depth), with little to no crystallization upon shallow ascent and eruption. Filter pressing, crystal settling, magma recharge and mixing of less evolved rhyolite melt, and volatile exsolution were important processes during magma evolution; the low estimated viscosities (10 super(5)-10 super(10)Pa s) of these H sub(2)O- and F-rich melts probably enhanced these processes. A noteworthy discrepancy between the metal contents in the pumice matrix glass and in the melt inclusions suggests that after quartz crystallization ceased upon shallow magma ascent and eruption, the Hideaway Park magma exsolved an aqueous fluid into which Mo, Bi, Ag, Zn, Mn, Cs, and Y strongly partitioned. Given that the Henderson deposit contains anomalous abundances of not only Mo, but also W, Pb, Zn, Cu, Bi, Ag, and Mn, we suggest that these metals were sourced from similar fluids exsolved from unerupted portions of the same magmatic system. Trace element ratios imply that Mo was sourced deep, from either the lower crust or metasomatized mantle. The origin of sulfur remains unresolved; however, given the extremely low S solubility of rhyolite melts in the shallow crust we favor the possibility that another source of S might supplement or account for that present in the ore deposit, probably the comagmatic, mantle-derived lamprophyres that occur in minor quantities with the voluminous topaz rhyolites in the area. To account for the 437Mt of MoS sub(2) (1.010 super(6)t Mo) present in the Henderson ore deposit, a volume of 45km super(3) of Hideaway Park rhyolite magma would have been necessary to supply the Mo (a cylindrical pluton measuring 3.1km6.0km) along with sparging of 6.810 super(5)t of S from 0.05km super(3) of lamprophyre magma. Based on a weighted mean super(40)Ar/ super(39)Ar age of 27.58 plus or minus 0.24Ma, similar melt geochemistry, and characteristically F-rich biotite phenocrysts, we conclude that the Hideaway Park tuff was cogenetic with the intrusions at Red Mountain that formed the Henderson deposit.

Alteration of historic habitats, including diking for agriculture, has decreased the function of many estuarine systems, and recent conservation efforts have been directed at restoring these degraded areas to reestablish their natural resource function. The Nisqually Delta in southern Puget Sound is an estuary that has been highly modified by restricting tidal flow, and recent restoration of the delta contributed to one of the largest tidal salt marsh restorations in the Pacific Northwest. We correlated the response of nine major tidal marsh species to salinities at different elevation zones. Our results indicated that wetland species richness was not related to soil pore-water salinity (R super(2) = 0.03), but were stratified into different elevation zones (R super(2) = 0.47). Thus, restoration that fosters a wide range of elevations will provide the most diverse plant habitat, and potentially, the greatest resilience to environmental change.

The modeling framework, introduced in the companion paper, uses a general set of conservation equations with flexibility in the choice of process parameterizations (closure relationships) and spatial architecture. This second paper specifies the model equations and their spatial approximations, describes the hydrologic and biophysical process parameterizations currently supported within the framework, and illustrates how the framework can be used in conjunction with multivariate observations to identify model improvements and future research and data needs. The case studies illustrate the use of SUMMA to select among competing modeling approaches based on both observed data and theoretical considerations. Specific examples of preferable modeling approaches include the use of physiological methods to estimate stomatal resistance, careful specification of the shape of the within-canopy and below-canopy wind profile, explicitly accounting for dust concentrations within the snowpack, and explicitly representing distributed lateral flow processes. Results also demonstrate that changes in parameter values can make as much or more difference to the model predictions than changes in the process representation. This emphasizes that improvements in model fidelity require a sagacious choice of both process parameterizations and model parameters. In conclusion, we envisage that SUMMA can facilitate ongoing model development efforts, the diagnosis and correction of model structural errors, and improved characterization of model uncertainty.

Fish-transport tables (termed Bates Tables) developed in 1955 do not take into consideration the fish loading process, commonly transported sensitive species, or physiological effects of elevated densities. To investigate suitability of the Bates Tables, effects of loading and transport at recommended and twice-recommended transport densities on physiological stress and survival of threadfin shad (Dorosoma petenense), Chinook salmon (Oncorhynchus mykiss), and striped bass (Morone saxatilis) were tested. Density did not have a significant effect on fish survival or physiological stress, as indicated by blood plasma constituent levels. At both densities, mean post-transport (168 hour) survival of all species was high (>98%), and ammonia and carbon dioxide levels increased in transport water as a result of fish metabolism, but levels remained below lethal levels. Among all species tested blood cortisol, glucose, and lactate levels followed a predictive adaptive response, with levels tending to peak immediately following transport and returning to basal levels within 24 hours.

We asked if pickleweed (Sarcocornia pacifica L, [Amaranthaceae]) colonization could be enhanced by experimental manipulation on these new wetlands. Pickleweed dominates ecologically important communities at adjacent San Francisco Bay, but is not typically dominant at Suisun Bay probably because of widely fluctuating water salinity and is outcompeted by other brackish water plants. Experimental treatments (1.0-m super(2) plots) included mulching with pickleweed cuttings in either the fall or the spring, tilling in the fall, or applying organic enrichments in the fall. Control plots received no treatment. Pickleweed colonization was most enhanced at treatment plots that were mulched with pickleweed in the fall. Since exotic vegetation can colonize bare sites within the early phases of restoration and reduce habitat quality, we concluded that mulching was most effective in the fall by reducing invasive plant cover while facilitating native plant colonization.

Combined with projections of population decline due to continued climate warming and the ensuing loss of sea ice habitat, those findings contributed to the 2008 decision to list the species as threatened under the U.S. Endangered Species Act. Here, we used mark-recapture models to investigate the population dynamics of polar bears in the southern Beaufort Sea from 2001 to 2010, years during which the spatial and temporal extent of summer sea ice generally declined. Low survival from 2004 through 2006 led to a 25-50% decline in abundance. We hypothesize that low survival during this period resulted from (1) unfavorable ice conditions that limited access to prey during multiple seasons; and possibly, (2) low prey abundance. For reasons that are not clear, survival of adults and cubs began to improve in 2007 and abundance was comparatively stable from 2008 to 2010, with 900 bears in 2010 (90% Cl 606-1212). However, survival of subadult bears declined throughout the entire period. Reduced spatial and temporal availability of sea ice is expected to increasingly force population dynamics of polar bears as the climate continues to Warm. However, in the short term, our findings suggest that factors other than sea ice can influence survival. A refined understanding of the ecological mechanisms underlying polar bear population dynamics is necessary to improve projections of their future status and facilitate development of management strategies.

AN - 1687678402; PQ0001568823 AB - Increased land use by polar bears (Ursus maritimus) due to climate-change-induced reduction of their sea-ice habitat illustrates the impact of climate change on species distributions and the difficulty of conserving a large, highly specialized carnivore in the face of this global threat. Some authors have suggested that terrestrial food consumption by polar bears will help them withstand sea-ice loss as they are forced to spend increasing amounts of time on land. Here, we evaluate the nutritional needs of polar bears as well as the physiological and environmental constraints that shape their use of terrestrial ecosystems. Only small numbers of polar bears have been documented consuming terrestrial foods even in modest quantities. Over much of the polar bear's range, limited terrestrial food availability supports only low densities of much smaller, resident brown bears (Ursus arctos), which use low-quality resources more efficiently and may compete with polar bears in these areas. Where consumption ofterrestrial foods has been documented, polar bear body condition and survival rates have declined even as land use has increased. Thus far, observed consumption of terrestrial food by polar bears has been insufficient to offset lost ice-based hunting opportunities but can have ecological consequences for other species. Warming-induced loss of sea ice remains the primary threat faced by polar bears.

The proliferation of non-native annual grasses has increased wildfire frequency and extent in recent decades and continues to accelerate the conversion of tortoise habitat across the Mojave Desert. Immediate changes to vegetation are expected to reduce quality of critical habitat, yet whether tortoises will use burned and recovering habitat differently from intact unburned habitat is unknown. We compared movement patterns, home-range size, behavior, microhabitat use, reproduction, and survival for adult desert tortoises located in, and adjacent to, burned habitat to understand how tortoises respond to recovering burned habitat. Approximately 45% of home ranges in the post-fire environment contained burned habitat, and numerous observations (n=12,223) corroborated tortoise use of both habitat types (52% unburned, 48% burned). Tortoises moved progressively deeper into burned habitat during the first 5 years following the fire, frequently foraging in burned habitats that had abundant annual plants, and returning to adjacent unburned habitat for cover provided by intact perennial vegetation. However, by years 6 and 7, the live cover of the short-lived herbaceous perennial desert globemallow (Sphaeralcea ambigua) that typically re-colonizes burned areas declined, resulting in a contraction of tortoise movements from the burned areas. Health and egg production were similar between burned and unburned areas indicating that tortoises were able to acquire necessary resources using both areas. This study documents that adult Mojave desert tortoises continue to use habitat burned once by wildfire. Thus, continued management of this burned habitat may contribute toward the recovery of the species in the face of many sources of habitat loss. Published 2015.

Chironomids were the major prey of common shiner (60.6%) and cutlip minnow (54.7%), whereas terrestrial invertebrates (30.0%) and amphipods (38.4%) were the primary food of fallfish and spottail shiner, respectively. Diet overlap was high between common shiner and cutlip minnow (Morisita's index = 0.88) and moderate between fallfish and common shiner (0.54) and fallfish and cutlip minnow (0.50). Diel temperal variation in diet composition was greatest (0.64) for spottail shiner. Three species exhibited diel variation in food consumption. Fallfish had a distinct feeding peak, whereas peak food consumption of common shiner and cutlip minnow occurred over a more extended period. Spottail shiner did not have a distinct feeding peak but food consumption was highest from 2400 to 0800 h. Each of the four species exhibited some degree of variation in their diel feeding ecology in regards to either diet composition or food consumption.

It is thought that soil moisture, and potentially disturbance, play important roles in determining abundance and flowering in this species. We present data for a P. praeclara population in southwestern Minnesota that has been monitored annually for 20 years. The number of flowering orchids varied over this period from 0 to 722. We provide an empirical test of an earlier model of precipitation effects during phenological life stages of the orchid, finding that the model was no better than a simple null model that ignored variability in precipitation. We re-examined the relationship between number of flowering orchids and precipitation during phenological life stages based on a modern information theoretic (AIC), multimodel inference approach, and a larger data set. The models indicate the importance of precipitation during three phases of orchid life history: (1) mature growth in the previous year; (2) postsenescence; and (3) emergence, explaining >70% of the variation in the number of flowering orchids. We also evaluated the effect of prescribed burns on this orchid population. Although we found no effect of fire on the number of flowering orchids, plants were shorter in burn years. This difference was not significant, however, once variation in precipitation was taken into account.

We investigated these drivers in limestone cedar glades, known for their concentrations of endemic plant species and for seasonal hydrologic extremes (xeric and saturated conditions), and compared our findings to those in temperate grasslands and semi-arid ecosystems. Methods: We measured R s , soil temperature (T s ), volumetric soil water content (SWC), soil organic matter (SOM), soil depth, and vegetation cover monthly over 16 mo and analyzed effects of these variables on R s. Results: Seasonally, R s primarily tracked T s (r super(2)=0.77; P<0.01), however R s was depressed during a summer drought. SOM was highly variable spatially, and incorporating SOM effects into the R s model dramatically improved model performance. Both shallow soil and sparse vegetation cover were also associated with lower R s. Conclusions: Soil depth, SOM, and vegetation cover were important drivers of R s in limestone cedar glades. Seasonal R s patterns reflected those for mesic temperate grasslands more than for semi-arid ecosystems, in that R s primarily tracked temperature for most of the year.

Under natural conditions in this flat landscape, water flowed slowly downstream as broad, shallow sheet flow. The ecosystem is markedly different now, altered by nutrient pollution and construction of canals, levees, and water control structures designed for flood control and water supply. These alterations have resulted in a 50 % reduction of the ecosystem's spatial extent and significant changes in ecological function in the remaining portion. One of the world's largest restoration programs is underway to restore some of the historic hydrologic and ecological functions of the Everglades, via a multi-billion dollar Comprehensive Everglades Restoration Plan. This plan, finalized in 2000, did not explicitly consider climate change effects, yet today we realize that sea level rise and future changes in rainfall (RF), temperature, and evapotranspiration (ET) may have system-wide impacts. This series of papers describes results of a workshop where a regional hydrologic model was used to simulate the hydrology expected in 2060 with climate changes including increased temperature, ET, and sea level, and either an increase or decrease in RF. Ecologists with expertise in various areas of the ecosystem evaluated the hydrologic outputs, drew conclusions about potential ecosystem responses, and identified research needs where projections of response had high uncertainty. Resource managers participated in the workshop, and they present lessons learned regarding how the new information might be used to guide Everglades restoration in the context of climate change.

Water budgets and stage hydrographs from this model with future scenarios of a 10 % increased or decreased rainfall, a 1.5 degree C rise in temperature and associated increase in evapotranspiration (ET) and a 0.5 m rise in sea level were used to predict resulting effects on soil biogeochemistry. Precipitation is a much stronger driver of soil biogeochemical processes than temperature, because of links among water cover, redox conditions, and organic carbon accumulation in soils. Under the 10 % reduced rainfall scenario, large portions of the Everglades will experience dry down, organic soil oxidation, and shifts in soil redox that may dramatically alter biogeochemical processes. Lowering organic soil surface elevation may make portions of the Everglades more vulnerable to sea level rise. The 10 % increased rainfall scenario, while potentially increasing phosphorus, sulfur, and mercury loading to the ecosystem, would maintain organic soil integrity and redox conditions conducive to normal wetland biogeochemical element cycling. Effects of increased ET will be similar to those of decreased precipitation. Temperature increases would have the effect of increasing microbial processes driving biogeochemical element cycling, but the effect would be much less than that of precipitation. The combined effects of decreased rainfall and increased ET suggest catastrophic losses in carbon- and organic-associated elements throughout the peat-based Everglades.

SDM is a value-focused thinking approach that places paramount importance on first establishing clear management objectives that reflect core values of stakeholders. To be useful for management, objectives must be transparently stated in unambiguous and measurable terms. We used these concepts to develop consensus objectives for the multiple stakeholders of horseshoe crab harvest in Delaware Bay. Participating stakeholders first agreed on a qualitative statement of fundamental objectives, and then worked to convert those objectives to specific and measurable quantities, so that management decisions could be assessed. We used a constraint-based approach where the conservation objectives for Red Knots, a species of migratory shorebird that relies on horseshoe crab eggs as a food resource during migration, constrained the utility of crab harvest. Developing utility functions to effectively reflect the management objectives allowed us to incorporate stakeholder risk aversion even though different stakeholder groups were averse to different or competing risks. While measurable objectives and quantitative utility functions seem scientific, developing these objectives was fundamentally driven by the values of the participating stakeholders.

We collected 214 invasive red lionfish samples from nine countries and territories, including seven unpublished locations. To more comprehensively evaluate connectivity, we compiled our d-loop sequence data with 846 published sequences, resulting in 1,060 samples from 14 locations. We found low nucleotide diversity ( pi = 0.003) and moderate haplotype diversity (h = 0.59). Using haplotype population pairwise Phi sub(ST) tests, we analyzed possible phylogeographic breaks that were previously proposed based on other reef organisms. We found support for the Bahamas/Turks/Caicos versus Caribbean break ( Phi sub(ST) = 0.12) but not for the Northwestern Caribbean, Eastern Caribbean, or US East Coast versus Bahamas breaks. The Northern Region had higher variation and more haplotypes, supporting introductions of at least five haplotypes to the region. Our wide-ranging samples showed that a lower-frequency haplotype in the Northern Region dominated the Southern Region and suggested multiple introductions, possibly to the south. We tested multiple scenarios of phylogeographic structure with analyses of molecular variance and found support for a Northern and Southern Region split at the Bahamas/Turks/Caicos versus Caribbean break (percentage of variation among regions = 8.49 %). We found that Puerto Rico clustered with the Southern Region more strongly than with the Northern Region, as opposed to previous reports. We also found the rare haplotype H03 for the first time in the southern Caribbean (Panama), indicating that either secondary releases occurred or that the low-frequency haplotypes have had time to disperse to extreme southern Caribbean locations.

Animal migrations often evolve to exploit seasonal variation in foraging opportunities. Many migrants move among discrete habitats using environmental cues to time their arrivals with seasonal peaks in food abundance. This type of migratory behaviour has been hypothesized to be particularly vulnerable to climate change, which can generate asynchrony between the seasonal timing (phenology) of animal movements and periods of resource abundance in destination habitats. 2. While many studies have documented climate-induced mismatches between migrants and the lower trophic levels they target, virtually none have explored the consequences of altered migration phenology on the higher trophic levels that migrants often subsidise. We explored the roles of climatic variation and prey migrations in driving the seasonal migrations of predators. 3. We show that in a warming catchment where prey migrations have changed substantially over the last 4 decades, migrations of Dolly Varden (Salvelinus malma) (predator) remain synchronised with annually variable Pacific salmon (Oncorhynchus spp.) (prey) migrations and appear to be cued directly by salmon migration rather than environmental conditions. 4. In contrast to many previous studies, our results suggest that some wide-ranging predators may be resilient to altered prey phenology.

California rangeland ecosystems have experienced substantial conversion to residential land use and more intensive agriculture. Objectives: To understand the potential impacts to rangeland ecosystem services, we developed six spatially explicit (250 m) climate/land use change scenarios for the Central Valley of California and surrounding foothills consistent with three Intergovernmental Panel on Climate Change emission scenario narratives. Methods: We quantified baseline and projected change in wildlife habitat, soil organic carbon (SOC), and water supply (recharge and runoff). For six case study watersheds we quantified the interactions of future development and changing climate on recharge, runoff and streamflow, and precipitation thresholds where dominant watershed hydrological processes shift through analysis of covariance. Results: The scenarios show that across the region, habitat loss is expected to occur predominantly in grasslands, primarily due to future development (up to a 37 % decline by 2100), however habitat loss in priority conservation errors will likely be due to cropland and hay/pasture expansion (up to 40 % by 2100). Grasslands in the region contain approximately 100 teragrams SOC in the top 20 cm, and up to 39 % of this SOC is subject to conversion by 2100. In dryer periods recharge processes typically dominate runoff. Future development lowers the precipitation value at which recharge processes dominate runoff, and combined with periods of drought, reduces the opportunity for recharge, especially on deep soils. Conclusion: Results support the need for climate-smart land use planning that takes recharge areas into account, which will provide opportunities for water storage in dry years. Given projections for agriculture, more modeling is needed on feedbacks between agricultural expansion on rangelands and water supply.

AN - 1666726888; 25678466 AB - The health of many Florida manatees (Trichechus manatus latirostris) is adversely affected by exposure to blooms of the toxic dinoflagellate, Karenia brevis. K. brevis blooms are common in manatee habitats of Florida's southwestern coast and produce a group of cyclic polyether toxins collectively referred to as red tide toxins, or brevetoxins. Although a large number of manatees exposed to significant levels of red tide toxins die, several manatees are rescued from sublethal exposure and are successfully treated and returned to the wild. Sublethal brevetoxin exposure may potentially impact the manatee immune system. Lymphocyte proliferative responses and a suite of immune function parameters in the plasma were used to evaluate effects of brevetoxin exposure on health of manatees rescued from natural exposure to red tide toxins in their habitat. Blood samples were collected from rescued manatees at Lowry Park Zoo in Tampa, FL and from healthy, unexposed manatees in Crystal River, FL. Peripheral blood leukocytes (PBL) isolated from whole blood were stimulated with T-cell mitogens, ConA and PHA. A suite of plasma parameters, including plasma protein electrophoresis profiles, lysozyme activity, superoxide dismutase (SOD) activity, and reactive oxygen/nitrogen (ROS/RNS) species, was also used to assess manatee health. Significant decreases (p<0.05) in lymphocyte proliferation were observed in ConA and PHA stimulated lymphocytes from rescued animals compared to non-exposed animals. Significant correlations were observed between oxidative stress markers (SOD, ROS/RNS) and plasma brevetoxin concentrations. Sublethal exposure to brevetoxins in the wild impacts some immune function components, and thus, overall health, in the Florida manatee. Copyright © 2015 Elsevier B.V. All rights reserved.

AN - 1657327007; 25576792 AB - We examined mercury (Hg) speciation in water and sediment of the Great Salt Lake and surrounding wetlands, a locale spanning fresh to hypersaline and oxic to anoxic conditions, in order to test the hypothesis that spatial and temporal variations in Hg concentration and methylation rates correspond to observed spatial and temporal trends in Hg burdens previously reported in biota. Water column, sediment, and pore water concentrations of methylmercury (MeHg) and total mercury (THg), as well as related aquatic chemical parameters were examined. Inorganic Hg(II)-methylation rates were determined in selected water column and sediment subsamples spiked with inorganic divalent mercury (204Hg(II)). Net production of Me204Hg was expressed as apparent first-order rate constants for methylation (kmeth), which were also expanded to MeHg production potential (MPP) rates via combination with tin reducible 'reactive' Hg(II) (Hg(II)R) as a proxy for bioavailable Hg(II). Notable findings include: 1) elevated Hg concentrations previously reported in birds and brine flies were spatially proximal to the measured highest MeHg concentrations, the latter occurring in the anoxic deep brine layer (DBL) of the Great Salt Lake; 2) timing of reduced Hg(II)-methylation rates in the DBL (according to both kmeth and MPP) coincides with reduced Hg burdens among aquatic invertebrates (brine shrimp and brine flies) that act as potential vectors of Hg propagation to the terrestrial ecosystem; 3) values of kmeth were found to fall within the range reported by other studies; and 4) MPP rates were on the lower end of the range reported in methodologically comparable studies, suggesting the possibility that elevated MeHg in the anoxic deep brine layer results from its accumulation and persistence in this quasi-isolated environment, due to the absence of light (restricting abiotic photo demethylation) and/or minimal microbiological demethylation.

Increasing dispersant dosage linearly enhanced solubility for all PAHs. Conversely, the dispersant enhanced the sediment uptake of the PAHs, and induced significant desorption hysteresis.

The simple exemption formula is often used as a criterion for the purpose of screening air pollutants. That is, the exemption formula is used for air quality review and to determine whether a facility applying for and described in a new, modified, or revised air quality plan is exempted from further air quality review. The Bureau of Ocean Energy Management's (BOEM) air quality regulations are used to regulate air emissions and air pollutants released from the oil and gas facilities in the Gulf of Mexico. If a facility is not exempt after completing the air quality review, a refined air quality modeling will be required to regulate the air pollutants. However, at present, the scientific basis for BOEM's exemption formula is not available to the author. Therefore, the purpose of this paper is to provide the theoretical framework and justification for the use of BOEM's exemption formula. In this paper, several exemption formulas have been derived from the Gaussian and non-Gaussian dispersion models; the Gaussian dispersion model is a special case of non-Gaussian dispersion model. The dispersion parameters obtained from the tracer experiments in the Gulf of Mexico are used in the dispersion models. In this paper, the dispersion parameters used in the dispersion models are also derived from the Monin-Obukhov similarity theory. In particular, it has been shown that the total amount of emissions from the facility for each air pollutant calculated using BOEM's exemption formula is conservative. Implications:The operation of offshore oil and gas facilities under BOEM's jurisdiction is required to comply with the BOEM's regulations. BOEM's air quality regulations are used to regulate air emissions and air pollutants released from the oil and gas facilities in the Gulf of Mexico. The exemption formulas have been used by BOEM and other regulatory agencies as a screening tool to regulate air emissions emitted from the oil and gas and other industries. Because of the BOEM's regulatory responsibility, it is important to establish the scientific basis and provide the justification for the exemption formulas. The methodology developed here could also be adopted and used by other regulatory agencies.

We excavated 29 buried living woody plants and used burial signatures in their annual rings to date stratigraphy in four trenches across the arroyos. Then, we reconstructed the history of arroyo evolution by combining trench data with arroyo-scale information from aerial imagery, light detection and ranging (LiDAR), longitudinal profiles, and repeat surveys of cross sections. Burial signatures in annual rings of salt cedar and willow dated sedimentary beds greater than 30 cm thick with annual precision. Along both arroyos, incision occurred until the 1930s in association with extreme high flows, and subsequent filling involved vegetation development, channel narrowing, increased sinuosity, and finally vertical aggradation. A strongly depositional sediment transport regime interacted with floodplain shrubs to produce a characteristic narrow, trapezoidal channel. The 55 km study reach along the Rio Puerco demonstrated upstream progression of arroyo widening and filling, but not of arroyo incision, channel narrowing, or floodplain vegetation development. We conclude that the occurrence of upstream progression within large basins like the Rio Puerco makes precise synchrony across basins impossible. Arroyo wall retreat is now mostly limited to locations where meanders impinge on the arroyo wall, forming hairpin bends, for which entry to and exit from the wall are stationary. Average annual sediment storage within the Rio Puerco study reach between 1955 and 2005 was 4.8 10 super(5) t/yr, 16% of the average annual suspended sediment yield, and 24% of the long-term bedrock denudation rate. At this rate, the arroyo would fill in 310 yr.

Sea-level rise (SLR) and changes in ocean chemistry make coastal regions among the most threatened habitats. The National Park Service (NPS), managing almost 12,000 km of shoreline, has an urgent need to characterize and predict the effects of climate change for mitigation and management purposes. The goal of this project is to develop a methodology framework for assessing the vulnerability of marine habitats within NPS, beginning with a pilot project at Cumberland Island National Seashore (CUIS). This framework employs a vulnerability assessment (VA) approach in which vulnerability is the sum of exposure (the magnitude of the stressor), sensitivity (how strongly a system is affected by the stressor), and adaptive capacity (the potential to adjust in response to the stressor). Four climate-change-related stressors were analyzed: SLR, temperature change, salinity change, and ocean acidification (OA). Within CUIS, the marine habitats of interest include subtidal and intertidal environments such as beach, salt marsh, shellfish beds, and tidal creeks. For each habitat-stressor combination, the exposure, sensitivity, and adaptive capacity were rated on a qualitative scale of low-medium-high. Preliminary results show the most vulnerable marine habitat at CUIS to be high-fringing salt marsh (HFSM), a narrow and sporadic zone between the expansive low salt marsh and the uplands. Topography, environmental conditions, cultural resources, and the encroaching low salt marsh make the HFSM sensitive to SLR and salinity, as well as reduce its potential to adapt (i.e., migrate inland). The changes in salinity and sea level would likely reduce the overall suitability for the growth of HFSM species (i.e., Juncus roemerianus) as well as increase competition, particularly with the ubiquitous low marsh species Spartina alterniflora. Preliminary field analysis at the site shows S. alterniflora growing sporadically in the HFSM at many locations within CUIS. Of the four stressors, SLR is of the greatest concern, given the immediacy of the threat and its high potential to disrupt sensitive habitats.

One of these core strategies is the acquisition of more accurate elevation data that can be used to predict changes in the coastal environment. While Light Detection and Ranging (LiDAR) data exists for the majority of coastal parks its elevation accuracy can vary from 5-30 cm (RMS) and may vary within any one collection area. In salt marshes, the error range maybe even greater and is mainly due to the effects of salt marsh vegetation and the inability of the LiDAR laser pulse to reach the marsh surface or platform. In salt marsh environments, vegetation zones are typically based on elevation (i.e., tidal inundation) and sometimes differ by only a few centimeters. LiDAR data therefore, is not accurate enough for evaluation of critical ecosystem functions like salt marsh elevation capital (loss or gain of marsh elevation with respect to water level). To better measure the elevation of the salt marsh surface, we used survey grade (cm accuracy) GPS equipment. Dual-frequency, carrier phase GPS surveying not only provides more accurate measurements of elevation than LiDAR, but also the ability to consistently measure the marsh platform. We present our field methods and initial results from 13 salt marsh sites at Assateague Island National Seashore collected in the fall of 2014. We collected comprehensive elevation data from the low marsh to the high marsh using a 20-m grid spacing. In addition, 8 water level loggers were deployed to better understand the tidal dynamics influencing these marshes.. Existing or temporary deep rod benchmarks established near each field site are utilized as survey control. These intensive on-the-ground kinematic GPS elevation data (along with water level data) will be used to tie all of these data to the North American Vertical Datum of 1988 and to calculate tidal datums specific to each salt marsh site. Thus, all of our data will be comparable which will help with the identification and prioritization of sites for management or conservation planning.

In glaciated settings, the formation and maintenance of a saltmarsh is complicated by steep upland boundaries and low sediment availability. In addition, many northern marshes have experienced anthropogenic alteration, such as ditching or tidal restriction. Boston Harbor contains over 30 small islands formed through the flooding and reworking of a drumlin field. Despite minimal sediment input from nearby fluvial systems, several of the islands exhibit small saltmarsh systems. While many studies have considered the development of larger saltmarshes in Massachusetts (e.g. the Great Marsh), little is known about the Harbor's isolated systems and their evolution throughout the Holocene. A series of auger and vibracores within two embayed saltmarshes (on Thompson and Peddocks Islands) provide a means for reconstructing both long- and short-term geomorphology. Radiocarbon dating of basal peats reveal that these marshes developed 2-4 ka when sea-level rise rates decelerated from approximately 3 mm/yr to 1 mm/yr. Using these data, we refine the Massachusetts sea-level curve, identifying a period of sea-level deceleration between 3.3 and 3.8 ka. More recent evolution is examined using vertical accretion rates (Pb (super 210) ) and surface elevation tables, which indicate Boston Harbor saltmarshes are presently keeping pace with sea-level rise (accretion of 3-6 mm/yr). Historically, however, much higher rates of accretion are observed on the Thompson marsh ( approximately 12 mm/yr), in response to the reopening of a dike. While numerical modeling suggests that sediment sourced from the nearby eroding drumlins may reach the marsh platforms, drumlin erosion has been reduced in recent years through shoreline protection. We suggest that the internal cannibalization of the marsh platform may explain these higher rates of platform accretion observed, despite the sediment-starved conditions.

Development of geochemical indicators of ground-ice residence times in permafrost will advance understanding of the circumstances and evidence of permafrost formation, preservation, and thaw in response to climate warming and other disturbance. We used uranium isotopes to evaluate the residence time of segregated ground ice from ice-rich loess permafrost cores in central Alaska. Activity ratios of (super 234) U vs. (super 238) U ( (super 234) U/ (super 238) U) in water from thawed core sections ranged between 1.163 and 1.904 due to contact of ice and associated liquid water with mineral surfaces over time. Measured ( (super 234) U/ (super 238) U) values in ground ice showed an overall increase with depth in a series of five neighboring cores up to 21 m deep. This is consistent with increasing residence time of ice with depth as a result of accumulation of loess over time, as well as characteristic ice morphologies, high segregated ice content, and wedge ice, all of which support an interpretation of syngenetic permafrost formation associated with loess deposition. At the same time, stratigraphic evidence indicates some past sediment redistribution and possibly shallow thaw among cores, with local mixing of aged thaw waters. Using measures of surface area and a leaching experiment to determine U distribution, a geometric model of ( (super 234) U/ (super 238) U) evolution suggests mean ages of up to approximately 200 ky BP in the deepest core, with estimated uncertainties of up to an order of magnitude. Evidence of secondary coatings on loess grains with elevated ( (super 234) U/ (super 238) U) values and U concentrations suggests that refinement of the geometric model to account for weathering processes is needed to reduce uncertainty. We suggest that in this area of deep ice-rich loess permafrost, ice bodies have been preserved from the last glacial period (10-100 ky BP), despite subsequent fluctuations in climate, fire disturbance and vegetation. Radiocarbon ( (super 14) C) analysis of dissolved organic carbon (DOC) in thaw waters supports ages greater than approximately 40 ky BP below 10 m. DOC concentrations in thaw waters increased with depth to maxima of >1000 ppm, despite little change in ice content or cryostructures. These relations suggest time-dependent production of old DOC that will be released upon permafrost thaw at a rate that is mediated by sediment transport, among other factors.

However, other pheromone components exist, and when 3kPZS alone was used to control invasive sea lamprey populations in the Laurentian Great Lakes, trap catch increase was significant, but gains were generally marginal. We hypothesized that free-ranging sea lamprey populations discriminate between a partial and complete pheromone while migrating to spawning grounds and searching for mates at spawning grounds. As a means to test our hypothesis, and to test two possible uses of sex pheromones for sea lamprey control, we asked whether the full sex pheromone mixture released by males (spermiating male washings; SMW) is more effective than 3kPZS in capturing animals in traditional traps (1) en route to spawning grounds and (2) at spawning grounds. At locations where traps target sea lampreys en route to spawning grounds, SMW-baited traps captured significantly more sea lampreys than paired 3kPZS-baited traps (~10 % increase). At spawning grounds, no difference in trap catch was observed between 3kPZS and SMW-baited traps. The lack of an observed difference at spawning grounds may be attributed to increased pheromone competition and possible involvement of other sensory modalities to locate mates. Because fishes often rely on multiple and sometimes redundant sensory modalities for critical life history events, the addition of sex pheromones to traditionally used traps is not likely to work in all circumstances. In the case of the sea lamprey, sex pheromone application may increase catch when applied to specifically designed traps deployed in streams with low adult density and limited spawning habitat.

This paper informs USA National Wildlife Refuge System conservation planning by predicting future land-use change on lands within 25 km distance of 461 refuges in the USA using an econometric model. The model contained two differing policy scenarios, namely a 'business-as-usual' scenario and a 'pro-agriculture' scenario. Regardless of scenario, by 2051, forest cover and urban land use were predicted to increase around refuges, while the extent of range and pasture was predicted to decrease; cropland use decreased under the business-as-usual scenario, but increased under the pro-agriculture scenario. Increasing agricultural land value under the pro-agriculture scenario slowed an expected increase in forest around refuges, and doubled the rate of range and pasture loss. Intensity of land-use change on lands surrounding refuges differed by regions. Regional differences among scenarios revealed that an understanding of regional and local land-use dynamics and management options was an essential requirement to effectively manage these conserved lands. Such knowledge is particularly important given the predicted need to adapt to a changing global climate.

Stream conservation is hindered by the lack of a universal habitat classification system and would benefit from an independent hydrology-guided spatial framework of units encompassing all aquatic habitats at multiple spatial scales within large regions. We present a system that explicitly separates the spatial framework from any particular classification developed from the framework. The framework was constructed from landscape variables that are hydrologically and biologically relevant, covered all space within the study area, and was nested hierarchically and spatially related at scales ranging from the stream reach to the entire region; classifications may be developed from any subset of the 9 basins, 107 watersheds, 459 subwatersheds, or 10,000s of valley segments or stream reaches. To illustrate the advantages of this approach, we developed a fish-guided classification generated from a framework for the Great Lakes region that produced a mosaic of habitat units which, when aggregated, formed larger patches of more general conditions at progressively broader spatial scales. We identified greater than 1,200 distinct fish habitat types at the valley segment scale, most of which were rare. Comparisons of biodiversity and species assemblages are easily examined at any scale. This system can identify and quantify habitat types, evaluate habitat quality for conservation and/or restoration, and assist managers and policymakers with prioritization of protection and restoration efforts. Similar spatial frameworks and habitat classifications can be developed for any organism in any riverine ecosystem.

Upon oxidation from metallic iron to iron oxide hydroxide, FeO(OH), particles underwent a significant transformation in size and morphology from 100 nm diameter spherical particles to plate-like crystalline particles with a hydrodynamic diameter greater than 450 nm. Atomic force microscopy (AFM) was used to mechanically degrade the FeO(OH) crystallites during repeated imaging. To determine whether similar degradation would occur during water filtration in a mixed matrix membrane, force under standard membrane operating conditions was calculated. Such force calculations were used to compare the shear forces exerted during water flux in a mixed matrix membrane to the normal forces imparted by AFM. Analysis suggested that the oxidized ZVI nanoparticles will experience a 10 super(-19) N maximum shear force in pore channels, much lower than the imaging forces in AFM, suggesting the mechanical stability of the particles during water remediation. Additional quartz crystal microbalance experiments were performed to confirm the mechanical stability of the oxidized iron nanoparticles in the flow environments of ultrafiltration. Taken together, the results of this study demonstrate that the mechanical properties of the nanoparticle composite membranes are such that minimal mechanical degradation of the nanoparticles will occur during water filtration.

Two of the sites included a pretreatment decarbonation step to exsolve CO sub(2(aq)) and reduce hydrate consumption due to hydroxylation and calcite formation. Decarbonation reduced the daily hydrated lime dose by 22 % at one site and 28 % at the other. Field-measured CO sub(2) mass transfer coefficients were determined for both decarbonation systems. CO sub(2) mass transfer modeling predicted that Ca(OH) sub(2) use would be reduced by an additional 19 and 28 % at these sites if the decarbonation systems were optimized. Hydroxylation of CO sub(2) species and calcite formation consume between 40 and 90 % of the Ca(OH) sub(2) dose. In terms of cost, more money is being spent on consumption due to hydroxylation and calcite formation than on removing the targeted parameter, ferrous iron. These processes can be minimized by improving decarbonation and oversizing ferrous reactor tanks to lower treatment pH.Original Abstract: Die Auswertung der Behandlung mit Kalkhydrat zur Entfernung von zweiwertigem Eisen aus den Drainagewaessern des Untertagekohlebergbau fand an vier Standorten in Pensylvania statt. Zwei Behandlungsanlagen beinhalteten eine Entkarbonisierungsstufe um CO2(aq) auszustrippen und damit den Hydratverbrauch durch Hydroxylierung und Calcitbildung zu senken. Durch die Entkarbonisierung konnte der Kalkhydratverbrauch in der einen Anlage um 22 % und in der anderen Anlage um 28 % gesenkt werden. Anhand vor Ort gemessener CO2-Werte wurden Massentransferkoeffizienten fuer beide Systeme zur Entkarbonisierung bestimmt. Die Modellierung des CO2-Massentransfers hat vorausgesagt, dass der Verbrauch an Ca(CO)2 um weitere 19 und 28 % durch die Optimierung der Entkarbonisierungsstufe gesenkt werden kann. Die Hydroxylierung der CO2-Spezies und die Calcitbildung zehren zwischen 40 und 90 % der Kalkhydratdosis auf. In Bezug auf die Kosten wird mehr Geld fuer das Kalkhydrat durch die Hydroxylierung und die Calcitbildung als fuer die Entfernung des Zielparameters (zweiwertiges Eisen) ausgegeben. Die Prozesse konnen durch eine Verbesserung der Entkarbonisierung und eine Ueberdimensionierung der Reaktionstanks zu einem niedrigeren pH-Wert minimiert werden.

Nonetheless, no synthesis of data collected on those species in Florida has been published until now. We searched the literature for peer-reviewed publications reporting original data for 42 species of non-native fishes in Florida that are currently established, were established in the past, or are sustained by human intervention. Since the 1950s, the number of non-native fish species increased steadily at a rate of roughly six new species per decade. Studies documented (in decreasing abundance): geographic location/range expansion, life- and natural-history characteristics (e.g., diet, habitat use), ecophysiology, community composition, population structure, behaviour, aquatic-plant management, and fisheries/aquaculture. Although there is a great deal of taxonomic uncertainty and confusion associated with many taxa, very few studies focused on clarifying taxonomic ambiguities of non-native fishes in the State. Most studies were descriptive; only 15 % were manipulative. Risk assessments, population-control studies and evaluations of effects of non-native fishes were rare topics for research, although they are highly valued by natural-resource managers. Though some authors equated lack of data with lack of effects, research is needed to confirm or deny conclusions. Much more is known regarding the effects of lionfish (Pterois spp.) on native fauna, despite its much shorter establishment time. Natural-resource managers need biological and ecological information to make policy decisions regarding non-native fishes. Given the near-absence of empirical data on effects of Florida non-native fishes, and the lengthy time-frames usually needed to collect such information, we provide suggestions for data collection in a manner that may be useful in the evaluation and prediction of non-native fish effects.

Museum records and historic data can be available at large scales across multiple decades, and are therefore an attractive source of information on the comparative status of populations. However, changes in populations may be real (e.g. in response to environmental covariates) or resulting from variation in our ability to observe the true population response (also possibly related to environmental covariates). This is a (statistical) nuisance in understanding the true status of a population. Evaluating statistical hypotheses alongside more interesting ecological ones is important in the appropriate use of museum data. Two statistical considerations are generally applicable to use of museum records: first without initial random sampling, comparison with contemporary results cannot provide inference to the entire range of a species, and second the availability of only some individuals in a population may respond to environmental changes. Changes in the availability of individuals may reduce the proportion of the population that is present and able to be counted on a given survey event, resulting in an apparent decline even when population size is stable.

Mussel tests were conducted in sediments sieved to <0.25mm to facilitate recovery of juvenile mussels (2-4 mo old). Sediments were contaminated primarily with lead, zinc, and cadmium, with greater zinc and cadmium concentrations in Tri-State sediments and greater lead concentrations in southeast Missouri sediments. The frequency of highly toxic responses (reduced 10% or more relative to reference sites) in Tri-State sediments was greatest for amphipod survival (25% of samples), midge biomass (20%), and mussel survival (14%). In southeast Missouri sediments, the frequency of highly toxic samples was greatest for mussel biomass (25%) and amphipod biomass (13%). Thresholds for metal toxicity to mussels, expressed as hazard quotients based on probable effect concentrations, were lower for southeast Missouri sediments than for Tri-State sediments. Southeast Missouri sites with toxic sediments had 2 or fewer live mussel taxa in a concurrent mussel population survey, compared with 7 to 26 taxa at reference sites. These results demonstrate that sediment toxicity tests with juvenile mussels can be conducted reliably by modifying existing standard methods; that the sensitivity of mussels to metals can be similar to or greater than standard test organisms; and that responses of mussels in laboratory toxicity tests are consistent with effects on wild mussel populations.

A wetland map that classifies wetlands according to carbon pools was created to describe future patterns of carbon loss and potential carbon savings. Wetland avoided loss scenarios, superimposed upon LULC change scenarios, quantified carbon stocks preserved under criteria of carbon densities or land value plus cropland suitability. Up to 3420 km super(2) of wetlands may be lost in the region by 2050, mainly due to conversion of herbaceous wetlands in the Temperate Prairies where soil organic carbon (SOC) is highest. SOC loss would be approximately 0.20 plus or minus 0.15 megagrams of carbon per hectare per year (MgC ha super(-1) yr super(-1)), depending upon tillage practices on converted wetlands, and total ecosystem carbon loss in woody wetlands would be approximately 0.81 plus or minus 0.41 MgC ha super(-1) yr super(-1), based on biogeochemical model results. Among wetlands vulnerable to conversion, wetlands in the Northern Glaciated Plains and Lake Agassiz Plains ecoregions exhibit very high mean SOC and on average, relatively low land values, potentially creating economically competitive opportunities for avoided carbon loss. This mitigation scenarios approach may be adapted by managers using their own preferred criteria to select sites that best meet their objectives. Results can help prioritize field-based assessments, where site-level investigations of carbon stocks, land value, and consideration of local priorities for climate change mitigation programs are needed.

AN - 1642609096; 25514764 AB - Chloride concentrations in northern U.S. included in this study have increased substantially over time with average concentrations approximately doubling from 1990 to 2011, outpacing the rate of urbanization in the northern U.S. Historical data were examined for 30 monitoring sites on 19 streams that had chloride concentration and flow records of 18 to 49 years. Chloride concentrations in most studied streams increased in all seasons (13 of 19 in all seasons; 16 of 19 during winter); maximum concentrations occurred during winter. Increasing concentrations during non-deicing periods suggest that chloride was stored in hydrologic reservoirs, such as the shallow groundwater system, during the winter and slowly released in baseflow throughout the year. Streamflow dependency was also observed with chloride concentrations increasing as streamflow decreased, a result of dilution during rainfall- and snowmelt-induced high-flow periods. The influence of chloride on aquatic life increased with time; 29% of sites studied exceeded the concentration for the USEPA chronic water quality criteria of 230 mg/L by an average of more than 100 individual days per year during 2006-2011. The rapid rate of chloride concentration increase in these streams is likely due to a combination of possible increased road salt application rates, increased baseline concentrations, and greater snowfall in the Midwestern U.S. during the latter portion of the study period.

Observed warming is related to timing and depth of influence of two potential thermal drivers-atmospheric temperature increases and urbanization. Results indicate that up to 30 % of groundwater warming at the water table can be attributed to atmospheric warming while up to 70 % of warming can be attributed to urbanization. Groundwater temperature readings to 30-m depth correlate positively with percentage of impervious cover and negatively with percentage of tree canopy cover; thus, these two land-use metrics explain up to 70 % of warming at the water table. Analytical and numerical modeling results indicate that an average vertical groundwater temperature profile for the study area, constructed from repeat measurement at 11 locations over 15 months, is consistent with the timing of land-use change over the past century in Virginia Beach. The magnitude of human-induced warming at the water table (+4.1 degree C) is twice the current seasonal temperature variation, indicating the potential for ecological impacts on wetlands and estuaries receiving groundwater discharge from shallow aquifers.Original Abstract: Des mesures de temperature des eaux souterraines dans un aquifere cotier peu profond a Virginia Beach, Virginia, Etats-Unis d'Amerique, suggerent un rechauffement des eaux souterraines de+4.1 degree C par rapport aux gradients geothermiques plus profonds. Le rechauffement observe est associe au timing et a la profondeur d'influence de deux parametres potentiels thermiques, a savoir l'augmentation de la temperature atmospherique et l'urbanisation. Les resultats indiquent que jusqu'a 30 % du rechauffement des eaux souterraines au niveau de la surface de la nappe peut etre attribue au rechauffement atmospherique alors que 70 % du rechauffement peut etre attribue a l'urbanisation. Les releves de temperature des eaux souterraines a 30 metres de profondeur sont correles positivement avec le pourcentage de la couverture impermeabilisee et negativement avec le pourcentage du couvert forestier; ainsi, ces deux metriques d'occupation du sol expliquent jusqu'a 70 % du rechauffement au niveau de la surface de la nappe phreatique. Les resultats de modelisation analytique et numerique indiquent que le profil vertical de la temperature moyenne des eaux souterraines pour la zone d'etude, construit a partir de mesures repetees en 11 points sur une periode de 15 mois, est compatible avec le timing du changement de l'occupation du sol au cours du dernier siecle a Virginia Beach. L'ampleur du rechauffement induit par l'activite humaine, de l'eau souterraine au niveau de la surface de la nappe phreatique (+4.1 degree C) est le double de la variation saisonniere actuelle de la temperature, indiquant les potentiels impacts ecologiques sur les zones humides et les estuaires alimentes par les eaux souterraines des aquiferes peu profonds.

The purpose of this study was to project the spatial and temporal aspects of carbon storage in the Greater Yellowstone Ecosystem (GYE) under these changes from 2006 to 2050. We selected three emission scenarios and produced simulations with the CENTURY model using three General Circulation Models (GCMs) for each scenario. We also incorporated projected land use change and fire occurrence into the carbon accounting. Results: The three GCMs showed increases in maximum and minimum temperature, but precipitation projections varied among GCMs. Total ecosystem carbon increased steadily from 7,942 gC/m super(2) in 2006 to 10,234 gC/m super(2) in 2050 with an annual rate increase of 53 gC/m super(2)/year. About 56.6% and 27% of the increasing rate was attributed to total live carbon and total soil carbon, respectively. Net Primary Production (NPP) increased slightly from 260 gC/m super(2)/year in 2006 to 310 gC/m super(2)/year in 2050 with an annual rate increase of 1.22 gC/m super(2)/year. Forest clear-cutting and fires resulted in direct carbon removal; however, the rate was low at 2.44 gC/m super(2)/year during 2006-2050. The area of clear-cutting and wildfires in the GYE would account for 10.87% of total forested area during 2006-2050, but the predictive simulations demonstrated different spatial distributions in national forests and national parks. Conclusions: The GYE is a carbon sink during 2006-2050. The capability of vegetation is almost double that of soil in terms of sequestering extra carbon. Clear-cutting and wildfires in GYE will affect 10.87% of total forested area, but direct carbon removal from clear-cutting and fires is 109.6 gC/m super(2), which accounts for only 1.2% of the mean ecosystem carbon level of 9,056 gC/m super(2), and thus is not significant.

Our study utilized data and modeling from a permafrost and ecosystem gradient to develop a mechanistic understanding of the short- and long-term impacts of tundra and boreal forest fires on soil thermal dynamics. Fires influenced a variety of factors that altered the surface energy budget, soil moisture, and the organic-layer thickness with the overall effect of increasing soil temperatures and thaw depth. The postfire thickness of the soil organic layer and its impact on soil thermal conductivity was the most important factor determining postfire soil temperatures and thaw depth. Boreal and tundra ecosystems underlain by permafrost experienced smaller postfire soil temperature increases than the nonpermafrost boreal forest from the direct and indirect effects of permafrost on drainage, soil moisture, and vegetation flammability. Permafrost decreased the loss of the insulating soil organic layer, decreased soil drying, increased surface water pooling, and created a significant heat sink to buffer postfire soil temperature and thaw depth changes. Ecosystem factors also played a role in determining postfire thaw depth with boreal forests taking several decades longer to recover their soil thermal properties than tundra. These factors resulted in tundra being less sensitive to postfire soil thermal changes than the nonpermafrost boreal forest. These results suggest that permafrost and soil organic carbon will be more vulnerable to fire as climate warms. Abstract Copyright (2015), American Geophysical Union. All Rights Reserved.

Dissolved CF4 concentrations in all groundwater samples but one were elevated with respect to estimated recharge concentrations including entrainment of excess air during recharge (; 30 fmolkg-1 H2O), indicating subsurface addition of CF4 to these groundwaters. Groundwaters in the Cuyama Valley contain small CF4 excesses (0.1-9 times ), which may be attributed to an in situ release from weathering and a minor addition of deep crustal CF4 introduced to the shallow groundwater through nearby faults. CF4 excesses in groundwaters within 200 m of the SAFS are larger (10-980 times ) and indicate the presence of a deep crustal flux of CF4 that is likely associated with the physical alteration of silicate minerals in the shear zone of the SAFS. Extrapolating CF4 flux rates observed in this study to the full extent of the SAFS (1300 km 20-100 km) suggests that the SAFS potentially emits CF4 yr-1 to the Earth's surface. For comparison, the chemical weathering of of granitic rock in California is estimated to release CF4 yr-1. Tectonic activity is likely an important, and potentially the dominant, driver of natural emissions of CF4 to the atmosphere. Variations in preindustrial atmospheric CF4 as observed in paleo-archives such as ice cores may therefore represent changes in both continental weathering and tectonic activity, including changes driven by variations in continental ice cover during glacial-interglacial transitions.

We use the 3-D spatial distribution of the hypocenters to refine the locations, strikes, and throws of subsurface faults interpreted previously from geophysical surveys and to infer the existence of previously unidentified subsurface faults. From distinct epicenter lineations and focal mechanism trends, we identify a set of conjugate fracture orientations consistent with shear-slip reactivation of late Paleozoic fractures over a widespread area, as well as an additional fracture orientation present only near the injection well. We propose simple Mohr-Coulomb fracture models to explain these observations. The observation that induced seismicity preferentially occurs along one of the identified conjugate fracture orientations can be explained by a rotation in the direction of the regional maximum compressive stress from the time when the fractures were formed to the present. Shear slip along the third fracture orientation observed near the injection well is inconsistent with the current regional stress field and suggests a local rotation of the horizontal stresses. The detailed subsurface model produced by this analysis provides important insights for anticipating spatial patterns of future induced seismicity and for evaluation of possible additional injection well sites that are likely to be seismically and hydrologically isolated from the current well. In addition, the interpreted fault patterns provide constraints for estimating the maximum magnitude earthquake that may be induced, and for building geomechanical models to simulate pore pressure diffusion, stress changes and earthquake triggering.

The total glacier-covered area in this region decreased by similar to 35% over the past 50 years, which has raised substantial concern about the loss of the water derived from glaciers during the summer. We used an innovative weather station design to collect in situ measurements on five remote glaciers, which are used to parameterize a regional glacier melt model. This model offered a first-order estimate of the summer meltwater production by glaciers. We find, during the normally dry month of August, glaciers in the region produce approximately 25 x 10 super(6) m super(3) of potential runoff. We then estimated the glacier runoff component in five gaged streams sourced from GNP basins containing glaciers. Glacier-melt contributions range from 5% in a basin only 0.12% glacierized to >90% in a basin 28.5% glacierized. Glacier loss would likely lead to lower discharges and warmer temperatures in streams draining basins >20% glacier-covered. Lower flows could even be expected in streams draining basins as little as 1.4% glacierized if glaciers were to disappear.

Understanding the dynamics of leachate movement in space and time is essential for monitoring, planning and management, and assessment of risk to groundwater and surface-water resources. Over a 23.4-year period (1986-2010), the spatial extent of the Norman Landfill leachate plume increased at a rate of 7800 m super(2)/year and expanded by 878 %, from an area of 20,800 m super(2) in 1986 to 203,400 m super(2) in 2010. A linear plume velocity of 40.2 m/year was calculated that compared favorably to a groundwater-seepage velocity of 55.2 m/year. Plume-scale hydraulic conductivity values representative of actual hydrogeological conditions in the alluvium ranged from 7.0x10 super(-5) to 7.5x10 super(-4) m/s, with a median of 2.0x10 super(-4) m/s. Analyses of field-measured and calculated plume-scale hydraulic conductivity distributions indicate that the upper percentiles of field-measured values should be considered to assess rates of plume-scale migration, spreading, and biodegradation. A pattern of increasing Cl super(-) concentrations during dry periods and decreasing Cl super(-) concentrations during wet periods was observed in groundwater beneath the landfill. The opposite occurred in groundwater downgradient from the landfill; that is, Cl super(-) concentrations in groundwater downgradient from the landfill decreased during dry periods and increased during wet periods. This pattern of changing Cl super(-) concentrations in response to wet and dry periods indicates that the landfill retains or absorbs leachate during dry periods and produces lower concentrated leachate downgradient. During wet periods, the landfill receives more recharge which dilutes leachate in the landfill but increases leachate migration from the landfill and produces a more concentrated contaminant plume. This approach of quantifying plume expansion, migration, and concentration during variable hydrologic conditions provides increased understanding of plume behavior and migration potential and may be applied at less monitored landfill sites to evaluate potential risks of contamination to downgradient receptors.

Postfire reassembly of vegetation - paramount to C storage and biodiversity conservation - frequently remains unpredictable and complicated by rapid global change. Using a unique data set of pre and long-term postfire data, combined with long-term data from nearby unburned areas, we examined 10 years of understory vegetation assembly after the 2002 Hayman Fire. This fire was the largest wildfire in recorded history in Colorado, USA. Resistance (initial postfire deviance from prefire condition) and resilience (return to prefire condition) declined with increasing fire severity. However, via both resistance and resilience, 'legacy' species of the prefire community constituted >75% of total plant cover within 3 years even in severely burned areas. Perseverance of legacy species, coupled with new colonizers, created a persistent increase in community species richness and cover over prefire levels. This was driven by a first-year increase (maintained over time) in forbs with short life spans; a 2-3-year delayed surge in long-lived forbs; and a consistent increase in graminoids through the 10th postfire year. Burning increased exotic plant invasion relative to prefire and unburned areas, but burned communities always were >89% native. This study informs debate in the literature regarding whether these increasingly large fires are 'ecological catastrophes.' Landscape-scale severe burning was catastrophic from a tree overstory perspective, but from an understory perspective, burning promoted rich and productive native understories, despite the entire 10-year postfire period receiving below-average precipitation.

For individual species, the threat of extinction is often used to prioritize what species are in need of conservation action. Using long-term monitoring data, we applied a Bayesian diffusion approximation to estimate quasi-extinction risk for 54 native fish species within six commercial navigation reaches along a 1350-km gradient of the upper Mississippi River system. We found a strong negative linear relationship between quasi-extinction risk and distance upstream. For some species, quasi-extinction estimates ranged from nearly zero in some reaches to one in others, suggesting substantial variability in threats facing individual river reaches. We found no evidence that species traits affected quasi-extinction risk across the entire system. Our results indicate that fishes within the upper Mississippi River system face localized threats that vary across river impact gradients. This suggests that conservation actions should be focused on local habitat scales but should also consider the additive effects on downstream conditions. We also emphasize the need for identification of proximate mechanisms behind observed and predicted population declines, as conservation actions will require mitigation of such mechanisms.

We used data from nuclear microsatellite and mitochondrial DNA control region loci to assess the breeding and non-breeding spatial genetic structure of a transoceanic migrant shorebird, the bristle-thighed curlew. We found spatial variance in the distribution of allelic and haplotypic frequencies between the curlew's two breeding areas in Alaska but did not observe this spatial structure throughout its non-breeding range on low-lying tropical and subtropical islands in the Central Pacific (Oceania). This suggests that the two breeding populations do not spatially segregate during the non-breeding season. Lack of migratory connectivity is likely attributable to the species' behavior, as bristle-thighed curlews exhibit differential timing of migration and some individuals move among islands during non-breeding months. Given the detrimental impact of many past and current human activities on island ecosystems, admixture of breeding populations in Oceania may render the bristle-thighed curlew less vulnerable to perturbations there, as neither breeding population will be disproportionally affected by local habitat losses or by stochastic events. Furthermore, lack of migratory connectivity may enable bristle-thighed curlews to respond to changing island ecosystems by altering their non-breeding distribution. However, availability of suitable non-breeding habitat for curlews in Oceania is increasingly limited on both low-lying and high islands by habitat loss, sea level rise, and invasive mammalian predators that pose a threat to flightless and flight-compromised curlews during the molting period.

Knowledge of the impacted area directly helps response and relief personnel in their efforts to reach and care for survivors and for re-establishing community services. First-hand accounts of tsunami-related impacts and consequences also help researchers, practitioners, and policy makers in other parts of the world that lack recent events to better understand and manage their own societal risks posed by tsunami threats. Conducting post-tsunami surveys and disseminating useful results to decision makers in an effective, efficient, and timely manner is difficult given the logistical issues and competing demands in a post-disaster environment. To facilitate better coordination of field-data collection and dissemination of results, a protocol for coordinating post-tsunami science surveys was developed by a multi-disciplinary group of representatives from state and federal agencies in the USA. This protocol is being incorporated into local, state, and federal post-tsunami response planning through the efforts of the Pacific Risk Management 'Ohana, the U.S. National Tsunami Hazard Mitigation Program, and the U.S. National Plan for Disaster Impact Assessments. Although the protocol was designed to support a coordinated US post-tsunami response, we believe it could help inform post-disaster science surveys conducted elsewhere and further the discussion on how hazard researchers can most effectively operate in disaster environments.

We used mitochondrial sequence and microsatellite data to assess the population genetics and phylogeography of unarmored populations sampled immediately downstream from the type locality of G. a. williamsoni in the upper Santa Clara River, and assessed their distinctiveness with respect to low-armor populations in the downstream sections of the river and the adjacent Ventura River. We also characterized the geographic limits of different plate morphs and evaluated the congruence of those boundaries with barriers to dispersal in both river systems and to neutral genetic variation. We show substantial population structuring within the upper reach of the Santa Clara River, but little partitioning between the lower Santa Clara and Ventura Rivers-we attribute these patterns to different ancestry between spatially subdivided populations within the same drainage, a predominance of downstream gene flow, and ability for coastal dispersal between the Santa Clara and Ventura Rivers. We also show that alleles from introduced low-plate stock have infiltrated a native population in at least one upper Santa Clara River tributary, causing this formerly unarmored population to become gradually low-plated over a 30 + year time period. Measures of genetic diversity, census surveys, and severe habitat disturbance all indicate that unarmored stickleback near the type locality are currently at high risk of extinction.

Soil samples collected within 300 m of an inactive Hg mine contained elevated Hg concentrations (3.8-11 mu g/g), which were considerably higher than Hg in soil collected from baseline sites (0.03-0.05 mu g/g) distal (as much as 24 km) from mines. Only three soil samples collected within 300 m of the mine exceeded the probable effect concentration for Hg of 1.06 mu g/g, above which harmful effects are likely to be observed in sediment-dwelling organisms. Concentrations of Hg in mine water runoff (7.9-14 ng/L) were generally higher than those found in springs and wells (0.05-3.1 ng/L), baseline streams (1.1-9.7 ng/L), and sources of drinking water (0.63-9.1 ng/L) collected in the Big Bend region. Concentrations of Hg in all water samples collected in this study were considerably below the 2,000 ng/L drinking water Hg guideline and the 770 ng/L guideline recommended by the U.S. Environmental Protection Agency (USEPA) to protect aquatic wildlife from chronic effects of Hg. Concentrations of Hg in water leachates obtained from leaching of mine wastes varied widely from <0.001 to 760 mu g of Hg in leachate/g of sample leached, but only one leachate exceeded the USEPA Hg industrial soil screening level of 31 mu g/g. Concentrations of Hg in soil gas collected at mined sites (690-82,000 ng/m super(3)) were highly elevated compared to soil gas collected from baseline sites (1.2-77 ng/m super(3)). However, air collected from mined areas at a height of 2 m above the ground surface contained concentrations of Hg (4.9-64 ng/m super(3)) that were considerably lower than Hg in soil gas from the mined areas. Although concentrations of Hg emitted from mine-contaminated soils and mine wastes were elevated, persistent wind in southwest Texas disperses Hg in the air within a few meters of the ground surface.

We examined seasonal patterns in periphyton fatty acids in six minimally disturbed headwater streams in Pennsylvania's Appalachian Mountains, USA. Environmental data and periphyton were collected across four seasons for fatty acid and algal taxa content. Non-metric multidimensional scaling ordination suggested significant seasonal differences in fatty acids; an ordination on algal composition revealed similar seasonal patterns, but with slightly weaker separation of summer and fall. Summer and fall fatty acid profiles were driven by temperature, overstory cover, and conductivity and winter profiles by measures of stream size. Ordination on algal composition suggested that summer and fall communities were driven by overstory and temperature, whereas winter communities were driven by velocity. The physiologically important fatty acid 18:3 omega 6 was highest in summer and fall. Winter samples had the highest 20:3 omega 3. Six saturated fatty acids differed among the seasons. Periphyton fatty acids profiles appeared to reflect benthic algal species composition. This suggests that periphyton fatty acid composition can be useful in characterizing basal food resources and stream water quality.

Specifically we account for the effects of a park's proximity, size, and greenness (measured by NDVI), as well as the presence of a public swimming pool. SFR households with and without home pools are analyzed separately. We control for SFR property attributes, including house size, age, yard size and property NDVI. Results suggest that SFR outdoor water use is influenced by the conditions of all parks within an 8km (5mile) street distance. We also find significant differences between the "with" and "without" home pool groups. Households with pools used more outdoor water per square meter of house, per year of house age and per unit of NDVI. Households without pools appeared to reduce outdoor use in response to nearby small parks and increased park NDVI. "With pool" households had the opposite response: they appeared to increase outdoor water use in response to these variables. However, "with pool" households did reduce their outdoor water use in response to nearby public pools. Medium and large parks were associated with increased outdoor water use for both groups. We conclude that public green space and pools can substitute for private versions of these amenities, and if well designed, can contribute to water demand management and urban sustainability. This may be an avenue for addressing water supply shortages in semi-arid cities and other areas where populations are growing but water supplies are finite.

Here, we document the spread of genetic introgression between a native (Oncorhynchus clarkii) and invasive (Oncorhynchus mykiss) trout, and identify the mechanisms influencing genetic admixture. In two populations inhabiting contrasting environments, non-native admixture increased rapidly from 1984 to 2007 and was driven by surprisingly consistent processes. Individual admixture was related to two phenotypic traits associated with fitness: size at spawning and age of juvenile emigration. Fish with higher non-native admixture were larger and tended to emigrate at a younger age-relationships that are expected to confer fitness advantages to hybrid individuals. However, strong selection against non-native admixture was evident across streams and cohorts (mean selection coefficient against genotypes with non-native alleles (s) = 0.60; s.e. = 0.10). Nevertheless, hybridization was promoted in both streams by the continuous immigration of individuals with high levels of non-native admixture from other hybrid source populations. Thus, antagonistic relationships between dispersal and selection are mediating invasive hybridization between these fish, emphasizing that data on dispersal and natural selection are needed to fully understand the dynamics of introgression between native and non-native species.

The fauna includes as many as nine distinct theropod taxa along with several indeterminate archosaurs and birds. Theropod tooth types (indeterminate tyrannosaurids, cf. Saurornitholestes, cf. Richardoestesia, cf. Paronychodon) are similar to those found in the upper shale member of the Aguja, as well as in other Campanian theropod assemblages from western North America. However, the most abundant tooth morphotype is unique, and attributed to a new varanoid lizard with remarkably theropod-like dentition, herein designated Dryadissector shilleri (gen. et sp. nov.). The presence of many unique theropod tooth morphotypes in the Lowerverse local fauna suggests that there remains significant undiscovered diversity among small theropods in southern latitude faunas, and accords with recognition of distinct latitudinal biomes during Campanian time in western North America. Due to their similar dentition, small theropods, along with varanoid lizards, may have served similar ecological roles as competitive mesopredators in the Campanian tropical predator guild.

Historical floods are simulated at two UTRB gauge locations, Farad and Reno, using the Variable Infiltration Capacity (VIC) model and non-stationary Generalized Extreme Value (GEV) models. The non-stationary GEV models are fit to the cool season (November-April) monthly maximum flows using historical monthly precipitation totals and average temperature. Future cool season flood distributions are subsequently calculated using downscaled projections of precipitation and temperature from the Coupled Model Intercomparison Project Phase 5 (CMIP-5) archive. The resulting exceedance probabilities are combined to calculate the probability of a flood of a given magnitude occurring over a specific time period (referred to as flood risk) using recent developments in design-life risk methodologies. This paper provides the first end-to-end analysis using non-stationary GEV methods coupled with contemporary downscaled climate projections to demonstrate the evolution of a flood risk profile over typical design life periods of existing infrastructure that are vulnerable to flooding (e.g., dams, levees, bridges and sewers). Results show that flood risk increases significantly over the analysis period (from 1950 through 2099). This highlights the potential to underestimate flood risk using traditional methodologies that do not account for time-varying risk. Although model parameters for the non-stationary method are sensitive to small changes in input parameters, analysis shows that the changes in risk over time are robust. Overall, flood risk at both locations (Farad and Reno) is projected to increase 10-20% between the historical period 1950 to 1999 and the future period 2000 to 2050 and 30-50% between the same historical period and a future period of 2050 to 2099.

PQ0001192658 AB - We characterized activity patterns of large cruise ships in Southeast Alaska, where there is considerable overlap with aggregations of endangered humpback whales and where lethal ship-whale collisions have been reported. Using Automatic Identification System (AIS) data from 451 voyages representing 26 cruise ships ([Image omitted.] = 270 m), we summarized traffic intensity, speed, and timing (day vs. night) for the 2012 summer cruise season in Southeast Alaska. Traffic intensity was found to exceed 700 transits in some areas, which constituted up to 10 ships transiting these areas per day during peak season. Throughout most of the study area (68% of 5 5 km cells) average ship speed was >16 knots, and often >18 knots. About half (47%) of the time spent cruising occurred at night when detection and avoidance of whales by ships is likely low. Although whales in Southeast Alaska were subject to low levels of shipping traffic relative to other major shipping routes, cruise ships transited throughout the majority of our study area at speeds where the probability for lethality, should a collision occur, is high, potentially offsetting the relatively low traffic levels. Our results help identify areas of greatest relative risk to whales and locations where whale conservation measures may be most effective.

Recovery can be further accelerated by understanding the factors controlling post-planting survival. In fall 2007 and 2009, we outplanted seedlings of two contrasting native evergreen shrubs-fast-growing Nevada jointfir and slow-growing blackbrush-across five burned sites in the Mojave Desert. To increase soil moisture and optimize seedling survival, we experimentally applied and evaluated soil amendments and supplemental watering. We also evaluated two herbicides that reduce competitive invasive annual grasses and two types of herbivore protection. Survival of jointfir outplanted in 2007 was 61% after 43 months, and site largely influenced survival, while herbicide containing imazapic applied more than one year after outplanting reduced survival. Reduced survival of jointfir outplanted in 2009 coincided with delayed seasonal precipitation that intensified foliar damage by small mammals. In contrast, blackbrush survival was 4% after 43 months, and was influenced by site, type of herbivore protection, and greenhouse during the 2007 outplanting, and soil amendment during 2009. Counter to expectations, we found that supplemental watering and soil amendments did not influence long-term survival of either blackbrush or jointfir. Shrub species with rapid growth rates and broad environmental tolerances, such as jointfir, make ideal candidates for outplanting, provided that seedlings are protected from herbivores. Re-introduction of species with slow growth rates and narrow environmental tolerances, such as blackbrush, requires careful consideration to optimize pre- and post-planting conditions.

Baseline paleontological resource inventories undertaken at Carlsbad Caverns National Park, Chaco Culture National Historical Park and White Sands National Monument have yielded important information on each parks vertebrate fossil record. Late Cretaceous marine and terrestrial vertebrates are preserved at Chaco Culture National Historical Park. Important assemblages of Pleistocene and Holocene vertebrate fossils are well documented from caves at Carlsbad Caverns National Park. An extensive Late Pleistocene megatracksite, consisting of thousands of vertebrate ichnofossils, has been documented in and around White Sands National Monument. A fourth NPS unit, Salinas Pueblo Missions National Monument, may have yielded mammoth remains, but the report is equivocal.

We defined marsh accretion parameters to encapsulate the range of observed values over historic and modern time-scales based on measurements from four marshes in high and low energy fluvial environments as well as possible future trends in sediment supply and mean sea level. A sensitivity analysis of 450 simulations was conducted encompassing a range of porosity values, initial elevations, organic and inorganic matter accumulation rates, and sea-level rise rates. For the range of inputs considered, the magnitude of SLR over the next century was the primary driver of marsh surface elevation change. Sediment supply was the secondary control. More than 84% of the scenarios resulted in sustainable marshes with 88 cm of SLR by 2100, but only 32% and 11% of the scenarios resulted in surviving marshes when SLR was increased to 133 cm and 179 cm, respectively. Marshes situated in high-energy zones were marginally more resilient than those in low-energy zones because of their higher inorganic sediment supply. Overall, the results from this modeling exercise suggest that marshes at the upstream reaches of the Delta-where SLR may be attenuated-and high energy marshes along major channels with high inorganic sediment accumulation rates will be more resilient to global SLR in excess of 88 cm over the next century than their downstream and low-energy counterparts. However, considerable uncertainties exist in the projected rates of sea-level rise and sediment availability. In addition, more research is needed to constrain future rates of aboveground and belowground plant productivity under increased CO2 concentrations and flooding.

Historically, California has buffered its water supplies and flood risks both within-and beyond-the Delta's catchment by developing many reservoirs, large and small, high and low. Most of these reservoirs carry water from wet winter seasons-when water demands are low and flood risks are high-to dry, warm seasons (and years) when demands are high and little precipitation falls. Many reservoirs are also used to catch and delay (or spread in time) flood flows that otherwise might cause damage to communities and floodplains. This essay describes the status of surface-water and snowpack storage conditions in California in spring 2015, providing context for better understanding where the state's water stores stand as we enter summer 2015.

The wild tortoises were from 11 sites in the states of Sonora and Sinaloa, and the captive tortoises were from the state-managed Centro Ecologico de Sonora Zoo in Hermosillo and a private residence in the town of Alamos. We tested 88 tortoises for mycoplasmal upper respiratory tract disease (URTD) using enzyme-linked immunosorbent assays for specific antibody and by culture and PCR for detection of Mycoplasma agassizii and Mycoplasma testudineum. Fifteen of 22 captive tortoises had one or more positive diagnostic test results for M. agassizii whereas no wild tortoises had positive tests. Tortoises with positive tests also had significantly more moderate and severe clinical signs of mycoplasmosis on beaks and nares compared to tortoises with negative tests. Captive tortoises also exhibited significantly more clinical signs of illness than did wild tortoises, including lethargy and moderate to severe ocular signs. The severity of trauma and diseases of the shell and integument did not differ significantly among tortoises by site; however, clinical signs of moderate to severe trauma and disease were more prevalent in older tortoises. Similar to research findings for other species in the genus Gopherus in the US, we found that URTD is an important disease in captive tortoises. If they escape or are released by intention or accident to the wild, captive tortoises are likely to pose risks to healthy, naive wild populations.

Most of the NPS TMDLs developed for California's Central Valley (CV) region were related to pesticides, but not nutrients. Efforts to reduce pesticide loads and concentrations began in earnest around 1990. The NPS control strategies either encouraged or mandated the use of management practices (MPs). Although TMDLs were largely developed for pesticides, the resultant MPs might have affected the runoff of other potential contaminants (such as nutrients). This study evaluates the effect of agricultural NPS control strategies implemented in California's CV before and between 1990 and 2013, on nutrients, by comparing trends in surface-water concentrations and loads. In general, use of MPs was encouraged during a "voluntary" period (1990 to 2004) and mandated during an "enforcement" period (2004 to 2013). Nutrient concentrations, loads, and trends were estimated by using a recently developed Weighted Regressions on Time, Discharge, and Season (WRTDS) model. Sufficient total phosphorus (TP), total nitrogen (TN), and nitrate (NO3) data were available to compare the voluntary and enforcement periods for twelve sites within the lower Sacramento and San Joaquin basins. Ammonia concentrations and fluxes were evaluated at a subset of these sites. For six of these sites, flow-normalized mean annual concentrations of TP or NO3 decreased at a faster rate during the enforcement period than during the voluntary period. Concentration changes during similar years and ranges of flow conditions suggest that MPs designed for pesticides may also have reduced nutrient loads. Results show that enforceable NPS policies, and accelerated MP implementation, limits NPS pollution, and may control runoff of non-targeted constituents such as nutrients.

More than 250 different crops are grown in the broad alluvial filled structural trough, with an estimated value exceeding $20 billion per year (Faunt 2009) (Figure 1). Central Valley agriculture depends on state and federal water systems that divert surface water, predominantly originating from Sierra Nevada snowmelt, to agricultural fields. Because the valley is semi-arid and the availability of surface water varies substantially from year to year, season to season, and from north to south, agriculture, as it grew, developed a reliance on groundwater for irrigation.

In the practice of wildlife conservation, to date most attention has focused on the threat EIDs pose to biodiversity and wildlife population viability. In the popular media and public eye, however, wildlife is often only portrayed as the cause of EIDs and resultant human health impacts. There is little coverage on the roles of human-induced habitat destruction or wildlife population stress in EID spread, nor the negative impacts of disease on wildlife. Here, we focus on a little-studied and seldom discussed concern: how real and perceived risks of wildlife-associated diseases for human and companion animal health might erode public support for wildlife conservation. We believe that wildlife-associated EIDs and public perceptions of these risks are among the most important threats to wildlife conservation. In light of this concern, we explore the challenges and opportunities for addressing this situation in a One Health context that emphasizes the interdisciplinary collaboration and the inextricable nature of human and animal health and disease.

Polar bears (Ursus maritimus) rely on a thick layer of adipose tissue and a dense pelage to ameliorate convective heat loss while moving between sea ice and open water. From 1998 to 2012, we observed an alopecia syndrome in polar bears from the southern Beaufort Sea of Alaska that presented as bilaterally asymmetrical loss of guard hairs and thinning of the undercoat around the head, neck, and shoulders, which, in severe cases, was accompanied by exudation and crusted skin lesions. Alopecia was observed in 49 (3.45%) of the bears sampled during 1,421 captures, and the apparent prevalence varied by years with peaks occurring in 1999 (16%) and 2012 (28%). The probability that a bear had alopecia was greatest for subadults and for bears captured in the Prudhoe Bay region, and alopecic individuals had a lower body condition score than unaffected individuals. The cause of the syndrome remains unknown and future work should focus on identifying the causative agent and potential effects on population vital rates.

NOV. CAUSES SKIN INFECTIONS THAT RESEMBLE WHITE-NOSE SYNDROME OF HIBERNATING BATS AN - 1837304865; PQ0003751741 AB - Before the discovery of white-nose syndrome (WNS), a fungal disease caused by Pseudogymnoascus destructans, there were no reports of fungal skin infections in bats during hibernation. In 2011, bats with grossly visible fungal skin infections similar in appearance to WNS were reported from multiple sites in Wisconsin, US, a state outside the known range of P. destructans and WNS at that time. Tape impressions or swab samples were collected from affected areas of skin from bats with these fungal infections in 2012 and analyzed by microscopy, culture, or direct DNA amplification and sequencing of the fungal internal transcribed spacer region (ITS). A psychrophilic species of Trichophyton was isolated in culture, detected by direct DNA amplification and sequencing, and observed on tape impressions. Deoxyribonucleic acid indicative of the same fungus was also detected on three of five bat carcasses collected in 2011 and 2012 from Wisconsin, Indiana, and Texas, US. Superficial fungal skin infections caused by Trichophyton sp. were observed in histopathology for all three bats. Sequencing of the ITS of Trichophyton sp., along with its inability to grow at 25 C, indicated that it represented a previously unknown species, described herein as Trichophyton redellii sp. nov. Genetic diversity present within T. redellii suggests it is native to North America but that it had been overlooked before enhanced efforts to study fungi associated with bats in response to the emergence of WNS.

We describe APMV-1 associated outbreaks in DCCO in the US from the first reported occurrence in 1992 through 2012. The frequency of APMV-1 outbreaks has increased in the US over the last decade, but the majority of events have continued to occur in DCCO colonies in the Midwestern states. Although morbidity and mortality in conesting species has been frequently reported during DCCO APMV-1 outbreaks, our results suggest that isolation of APMV-1 is uncommon in species other than DCCO during APMV-1 outbreaks and that the cause of mortality in other species is associated with other pathogens. Populations of DCCO do not appear to have been significantly affected by this disease; however, because at least 65% of the APMV-1 outbreaks in DCCO in the US have involved APMV-1 strains classified as virulent to poultry (virulent Newcastle disease virus), its persistence and increased occurrence in DCCO warrants continued research and surveillance.

Ocean acidification models project that the global average pH of the surface ocean will decline from a current value of 8.1 in 2015 ([CO (sub 2atm) ] approximately 400 ppm) to 7.6 in 2140 ([CO (sub 2atm) ] approximately 1,300 ppm). At pH 8.0, 88% of total carbon (CT) is in the form of HCO (sub 3) (super -) and 12% is present as CO (sub 3) (super 2-) ; while at pH 7.6, 94% is HCO (sub 3) (super -) and 4% is CO (sub 3) (super 2-) . Two species, Amphistegina gibbosa (Order Rotaliida) and Archaias angulatus (Order Miliolida), were studied to assess the effects of pH 7.6 seawater on oxygen and carbon isotope discrimination during test construction. Tests of juveniles produced during the six-week culture period showed significant differences between delta (super 18) O and delta (super 13) C values from control (pH 8.0) vs the treatments (pH 7.6) for both species. Specifically, Am. gibbosa delta (super 18) O was significantly (p<0.001) higher in specimens from the pH 7.6 treatment (-0.37+ or -0.1 ppm) than from the pH 8.0 control (-1.10+ or -0.09 ppm). Additionally, delta (super 13) C was significantly higher (p <0.001) at pH 7.6 (0.57+ or -0.25 ppm) than at pH 8.0 (-1.86+ or -0.32 ppm). Ar. angulatus delta (super 18) O was also significantly (p<0.001) higher at pH 7.6 (0.08+ or -0.06 ppm) than at ph 8.0 (-0.80+ or -0.15 ppm); though the delta (super 13) C was not significantly different (p=0.23). However, separate analysis of adult terminal chambers and of whole adult tests of both species after six weeks of pH treatment at 7.6 and 8.0 showed no significant differences. Juvenile specimens formed during the culture period did not contain pre-existing carbonate that confounds the isotopic signal of experimental pH. Precisely distinguishing and extracting newly precipitated calcite in adult specimens is difficult and mixing with pretest material likely diluted the differences in isotopic composition recorded from the different growth phases. This reveals a potential bias in ocean acidification experiments when changes in test chemistries are investigated using only adult tests. Combined, these results reaffirm that the differences in calcification mechanisms of the two species from different foraminiferal orders, control the effect on stable isotopic composition of tests and will consequently reflect the decreasing seawater pH as ocean acidification proceeds.

We show that the Nisqually and Emmons glaciers have small slope-parallel velocities near the summit ( (sub 0.2 m day (super -1) ), high velocities over their upper and central regions (1.0-1.5 m day (super -1) ), and stagnant debris-covered regions near the terminus ( (sub 0.05 m day (super -1) ). Velocity uncertainties are as low as + or -0.02-0.08 m day (super -1) . We document a large seasonal velocity decrease of 0.2-0.7 m day (super -1) (-25 to -50 %) from July to November for most of the Nisqually Glacier, excluding the icefall, suggesting significant seasonal subglacial water storage under most of the glacier. We did not detect diurnal variability above the noise level. Simple 2-D ice flow modeling using TRI velocities suggests that sliding accounts for 91 and 99 % of the July velocity field for the Emmons and Nisqually glaciers with possible ranges of 60-97 and 93-99.5 %, respectively, when considering model uncertainty. We validate our observations against recent in situ velocity measurements and examine the long-term evolution of Nisqually Glacier dynamics through comparisons with historical velocity data. This study shows that repeat TRI measurements with (super 10 km range can be used to investigate spatial and temporal variability of alpine glacier dynamics over large areas, including hazardous and inaccessible areas.

Unfortunately, taphonomic and preservational biases, as well as small sample sizes have led to poor ichnotaxonomic naming and misidentifications. As it is likely that variation in track data is partially due to differing measurement and documentation techniques, more refined and standardized measuring methods are required. Fortunately, properly collected and processed close-range photogrammetric (CRP) projects can assist in the documentation, preservation, and assessment of the subtle, low relief, and often small size of many pterosaur ichnites. CRP image collection is ideal for pterosaur tracksites of various extents, exposures, and orientations; and allows for a more objective understanding of ichnotaxomic variations, as well as the recordation of novel ichnites that may reflect the kinetics of a diversity of pterosaur movements and activities. In the 1970s, abundant Late Jurassic pterosaur tracksites discovered in central Wyoming on Federal Public Lands were some of the first pterosaur tracksites to be recorded following Stokes' initial documentation (1957) of a pterosaur trackway in Arizona. In particular, the exposures of the Sundance and Morrison formations around Alcova and Seminoe reservoirs contain hundreds of tracks and trackways of the ichnogenus Pteraichnus and may represent some of the highest concentrations of pterosaur tracks anywhere in the world. The Paleontological Resources Preservation Act (PRPA) mandates the protection and interpretation of these scientifically significant paleontological resources. PRPA requires the management of paleontological resources on public lands using scientific principles and expertise and authorization is required for any scientific study of ichnological material, as well as for molding and casting. BLM is actively developing plans for inventorying, monitoring, and scientific and educational use of ichnological resources. Photogrammetric ichnology not only supports PRPA, but also is being used to help unravel ichnological complexities to provide a unique glimpse of the paleoecology, paleobiology, and paleoethology of these pterosaur communities.

This is due in large part to the use of digital cameras and the availability of user friendly software processing, as well as the cost effective and non-invasive nature of data collection. However, the use of photogrammetry need not be limited to single tracks and trackways. It has proven to be an effective method to capture very detailed surface information on entire tracksites with large contiguous areas of exposure. By following basic principles of photogrammetric best practice; taking photos nadir to the surface, using a wide-angle lens, fixing the focus, overlapping in-strip photos by 66% and between-strip photos by 50%, adding crossing strips, and processing the photos in a software that supports robust camera calibration and error identification and reduction; it is possible for photogrammetric data to achieve a precision of 0.1 mm for areas covering 100's of square meters. By following these best practices, accuracies may be reported with confidence. The outputs generated from the photogrammetric process are compatible with standard GIS software and include orthophotomosaics, color depth maps, and topographic maps with contour intervals as fine as 2 mm. As with any geologically based discipline, field observations and analyses are key to understanding ichnological features. The tracings, maps, and track measurements of trained ichnologists (vital to interpreting the complex sequence of events that took place in the distant past) can be easily integrated with the 3D digital product. The Mill Canyon Dinosaur Tracksite (MCDT) north of Moab, UT is an excellent example of the integration of field and photogrammetric documentation. This Lower Cretaceous tracksite (administered by the BLM's Moab Field Office) contains a diverse vertebrate ichnofauna with a minimum of 10 named ichnotaxa, including dinosaurian, crocodilian and bird tracks. An interpretive trail with raised boardwalk and informational signs help the visitor to navigate and understand this dynamic snapshot of life from the Early Cretaceous. The MCDT project is one of a number of large tracksite photogrammetric projects that have been completed worldwide using state-of-the-art techniques.

During 2010-2013 the National Park Service completed a comprehensive inventory of AMLs that identified 37,050 individual abandoned mine and oil and gas well features in 133 national park units. Of these, 1,799 features (4.9%) already have received long-term remedial action to address human health and safety and environmental problems, and 3,814 features (10.3%) in 76 parks still need remedial action. The remaining 31,437 features were recorded for purposes of general site characterization, but these require no action.

The in-situ exhibit was created by the collaboration of paleontologists and National Park Service (NPS) employees spanning over seventy-five years. Shortly after the excavations of the Carnegie Quarry began, the great size of the fossiliferous deposit was realized, and paleontologist Earl Douglass expressed the idea of an in-situ exhibit. Early planning efforts within the NPS illustrated the struggles over the exhibit concept at Carnegie Quarry. The approaches debated included: 1) a suggestion that the bones be excavated, reassembled into articulated skeletons, attached to wooden panels, and mounted to the quarry face, and 2) a proposal to paint the in-situ bones with fluorescent paint so they would glow in the dark. NPS officials expressed the concern that the unexcavated portion of the quarry would become less fossiliferous down dip. One proposal was to use radar, a recently developed technology, to locate bones still hidden within the five meter thick sandstone bed. In the early 1950s paleontologist Ted White began and directed new relief work, partially under a temporary quarry shelter. A permanent Quarry Visitor Center would be opened in 1958. The Quarry Visitor Center belonged to Mission 66, an effort by the NPS to replace old visitor centers around the country with more architecturally sound and modern successors. The Quarry Visitor Center, designed by the architectural firm of Anshen and Allen, helped shape the interpretive plan for the National Park Service for Carnegie Quarry. More than thirty years of fossil relief work in the Quarry Visitor Center has brought the development of Carnegie Quarry exhibit to completion with the modern in-situ exhibit seen today.

The region is also notable for evidence of significant volcanism, with fossil bearing volcaniclastic sedimentary rocks interrupted by relatively frequent and sprawling ignimbrites, flood basalts, and tuff layers. The abundance of volcanic strata provides numerous radiometric dates for biostratigraphic calibration. Recent revisions of the biostratigraphy and biodiversity of the Turtle Cove Member of the John Day Formation ( approximately 32 Ma - 25.9 Ma) provide an opportunity to conduct a high-resolution analysis of changes in paleoecology in respect to climate change and volcanic activity. The Turtle Cove Member consists of 6 dated tuff and ignimbrite layers located amongst 14 distinct fossiliferous units that yield a variety of ungulates (hoofed mammals), including hypertragulids (mouse-deer), camelids (camels), merycoidodontids (oreodonts), agriochoerids (clawed oreodonts), equids (horses), and rhinocerotids (rhinoceroses). The relative abundances of these mammals indicate a shift from closed habitats to more open habitats following a supervolcanic eruption (the Picture Gorge Ignimbrite, 28.7 Ma). Here we present the results of an extensive survey of the tooth wear (microwear and mesowear) of over 300 specimens of Turtle Cove ungulates. We quantified mesowear (i.e., the shape and relief of tooth cusps) and microwear (i.e., the relative abundance of microscopic scratches and pits) as proxies for habitat openness, based on the previously reported correlation between exogenous silica (e.g., soil) and the abrasion of tooth enamel. Our preliminary results indicate periods of increased tooth abrasion levels across taxa, following the larger volcanic events. These proxies suggest large volcanic events periodically increased habitat openness and played prominent roles in ungulate ecology and biodiversity in the John Day Basin during the early Oligocene.

This can be attributed to the challenging nature of the region, as little can be seen on aerial imagery through thick boreal and ponderosa pine forests. Field reconnaissance has several limitations due to the vastness of the watersheds and extremities of the region in weather and topography. Recent lidar data provides a detailed look at the plateau's surface morphology, highlighting the highly-developed karst topography, with over 1,800 sinkholes, an increase of over 350% from the park's original map and field-based karst features dataset. Previous research suggests that the deep regional Redwall-Muav aquifer is recharged by meteoric waters travelling through faults and open joints fed by sinkholes. However, the locations and/or distribution of transmitting sinkholes are unknown. Geospatial sinkhole analysis was conducted, using ArcGIS (version 10.2.2.), to better understand how these surficial karst features are connected to the deep regional Redwall-Muav aquifer. Sinkholes identified with the use of lidar data were sub-classified based on calculated geometries into karst feature types: patterned ground, cleft (linear), escarpment, and large sinkholes. The relationships between these features and mapped structural geology were then assessed. We found cleft sinkhole groups to be most juxtaposed to or aligned with fractures and/or open joints, and therefore this sinkhole type is most likely to have the strongest hydrologic connection to the regional aquifer. This geospatial analysis of sinkhole morphology and distribution presents a GIS-based approach to modelling the relative importance of individual sinkholes or sinkhole complexes to aquifer recharge. Results suggest that sinkhole geometry can be used to interpret the overall importance of a sinkhole to aquifer recharge, and that observing the morphology of these features at a regional scale can improve our understanding of aquifer vulnerability, enabling improved monitoring and management decisions.

These collections were distributed to at least 17 different museums based on affiliations of the original researchers. The National Park Service (NPS) completed on-site collection inventories at all of these repositories in order to develop a database documenting all published specimens including catalog records, new digital images, and corresponding publications. This database culminated in a website that was completed by the NPS and made available to the public in 2002. A new, ongoing project was initiated in 2007, in collaboration with the University of Colorado at Boulder, to migrate and update the data into a customized application of Specify 6. This new application provides the benefits of being able to easily add new data, edit existing data, and the ability to export data as a Darwin Core Archive, which facilitates sharing these data with other paleontology and biodiversity portals via the University of Colorado Museum of Natural History's IPT server. Another benefit of moving the data into Specify 6 is a customizable web application that allows for searching a cache of the data directly via the project website. The website provides a single source for data management that can be used by museum repositories, researchers, and government agencies for multiple purposes in locating Florissant specimens and publications, compiling taxonomic lists, and providing information useful in resource management.

This year in honor of the monument's centennial, it is taking steps to digitize and implement an interactive website focusing on the Carnegie Quarry. The Digital Quarry Project is a collaborative effort between the National Park Service staff, the Geological Society of America's GeoCorps and Mosaics programs, and Brigham Young University faculty and students. Its objective is to make the science and history of the quarry easily available to the public, as well as aid researchers in their quest for new interpretations and ideas. The Digital Quarry Project will provide researchers with a comprehensive, interactive quarry map that includes anatomical, taxonomic, and catalog data as well as photographs and historical documents relating to the specimens and excavations. In the future, this ambitious project will include both the quarry wall in its present form, the historical excavation maps, and photogrammetric data to illuminate the heterogeneous nature of the sedimentology of the quarry for those with research interests in deposition and taphonomy. The Digital Quarry Project will be the most comprehensive and accessible record of Carnegie Quarry. The presentation will include a demonstrative tour of the Digital Quarry.

These figurines are most likely associated with a hunting ritual performed by the Middle to Late Archaic peoples who inhabited the canyon from 4200 to 3100 14C years BP. Unlike similar figurines from other areas of the American Southwest, the placement of Grand Canyon split twig figurines show an apparent correlation with significant Quaternary megafauna cave deposits, specifically the bones, teeth, and dung of the extinct Harrington mountain goat (Oreamnos harringtoni) and extant Bighorn sheep (Ovis canadensis). To determine if the Archaic peoples were selecting caves for paleontological remains or accessibility, we analyzed the relationships between these variables for Grand Canyon caves containing split twig figurines or features known to be associated with the presence of the figurines (cairns, partially split twigs) as potential sites to all non-figurine Grand Canyon caves. While there is no significant relationship between the ease of access, measured in slope angle of entrance, and presence of split twig figurines, 80% of figurine caves and 40% of potential figurine sites are known to contain the remains of artiodactyls. This relationship is significant when compared to non-figurine Grand Canyon caves, where only 12% of caves contain the confirmed remains of artiodactyls. Given that O. harringtoni has been extinct in the canyon since 11,060 years BP, this relationship may represent the earliest occurrence of prehistoric people deliberately placing cultural remains near in situ fossil deposits (Emslie et al., 1995). This apparent correlation between artiodactyla deposits and the Grand Canyon split twig figurine complex highlights a unique relationship between prehistoric peoples and their environment amidst an increase in climate variability during the Late Holocene in the American Southwest.

Mount Baldy is the largest parabolic dune along the southern coast of Lake Michigan and is rapidly migrating onshore over a previously stabilized late Holocene landscape. Since 2013 multiple holes have been observed to appear in sands that directly overly a stabilized relict parabolic dune that supported oak (Quercus spp.) trees visible on the 1939 aerial photo. This study focused on the analyses of fungi collected from trees uneartherd from the dune and SEM analyses of sediment collected in contact with organic material. Data indicate that saprotrophic wood decay fungi continue to actively decompose trees after burial and facilitate the biomineralization of a calcium carbonate-rich cement at the contact between the organic material and sands. Scanning electron microscopy of the cement showed neoformed authigenic minerals and organic structures consistent in morphology with fungal hyphae. We propose that within the dune, portions of the decayed trees progressively collapse and infill, producing voids that are temporarily stabilized by the calcium carbonate-rich cement. Photographic evidence suggests that similar holes have occurred in migrating dune systems in Oregon and Michigan. Ongoing work must address the dynamics of fungal communities operating within trees pre and post burial and evaluate environmental conditions within the dune's interior to better understand the processes of biomineralization and decomposition that lead to the final collapse of buried trees.

Declining flows and water quality, channel narrowing and the influx of invasive vegetation and sediment have negatively affected the geomorphic condition and the aquatic habitat of the river. The Boquillas canyon reach of the Rio Grande includes approximately 17 miles of steep wall limestone canyon in the eastern part of Big Bend National Park. Topographic surveys of selected sand and gravel bars in the canyon have been conducted periodically since 2004 in order to monitor the geomorphic condition in the canyon. This study reports results for 4 topographic data sets collected along the river near the entrance to Boquillas canyon. Data were collected in 2004 in the form of 3 cross sections, in 2011 and 2013 in the form of traditional survey techniques using Total Station and RTK GPS, and in 2012 in the form of an aerial LIDAR survey. An area of interest was established as a bounding polygon that included full coverage for the 2011 to 2014 data, and a technique was developed to extrapolate the 2004 cross section data to estimate topographic change from 2004 for the same area. Results indicate a net volume loss between 2004 and 2011 of 40,517 m (super 3) . This loss was due to a large channel resetting flood event that occurred in 2008. The net volume change between 2011 and 2012 was 99 m (super 3) gained. This was a period of drought and overall low flow resulting in very little topographic change. An overall net gain of 4,482 m (super 3) was recorded for the 2012 to 2013 time period. The bulk of this gain was recorded as deposition in a small high flow channel. This observed sediment gain supports the hypothesis of gradual channel narrowing following periodic high flow channel resetting events (Dean and Schmidt, 2010).

Our ongoing work to determine post-fire erosion hazards in the Boise Foothills of southwest Idaho is part of a larger project to inform citizens of the fire and fire-induced hazards that threaten residents living within the 'fire-plain' of the Wildland Urban Interface (WUI). Like many cities in the western US (e.g. Denver, Reno, Salt Lake City), the Boise WUI is located at the base of a mountain front. These vegetative communities are typified by shrubs (sagebrush steppe) and grasslands at lower elevations, with open forests at higher elevations and on north-facing slopes. Despite increasing WUI development concurrent with growing fire and erosion hazards in these ecosystems, most erosion and fuel models are not catered to these systems. Using models developed by Cannon et al. (2010), we have identified several basins predicted to pose post-fire debris flow hazards in the Boise WUI. Our work, presented here, seeks to identify discrepancies in post-fire debris flow models that may arise as the result of applying models used in forested environments to areas for which they were not calibrated; namely the Boise Foothills and, more generally, rangeland ecosystems. We hypothesize that model predictions for the Boise Foothills overestimate the volume of sediment deposited subsequent to fire and that the mode of deposition will more often be sheetflooding rather than debris flows. Prior studies in Idaho have shown that lower severity fires burning on open grassland and sagebrush-steppe dominated slopes produce more frequent erosion events of lower magnitude (smaller debris flows and sheetfloods) compared to post-fire erosion following high-severity fire in forested landscapes, where sediment storage capacity is higher and debris flows predominate (Pierce et al., 2004; Weppner et al., 2013: Riley et al., 2015). Translating this understanding of rangeland post-fire erosion response to current predictive models is needed to better inform WUI residents of the hazards that threaten them at the intersection of rangeland and forest ecosystems.

The drastically lower temperatures produced by hypolimnetic releases from Glen Canyon Dam have reduced populations of this species, as has predation by non-native trout. Shinumo Creek is a relatively high gradient perennial stream (92 m/km) that receives baseflow from springs primarily in the Redwall-Muav limestone formations. Overland flow from the Kaibab Plateau, also the recharge area for the springs, occurs following the winter snows and during brief intense monsoonal storms during summer months. The lightning-caused Galahad Fire was discovered May 23, 2014, and burned 2484 hectares of ponderosa pine forest in the headwaters of the creek ( approximately 10% of the watershed), with a portion burned below the rim on extremely steep slopes. Subsequent monsoonal events caused two large floods later in the summer: the first was observed to carry substantial charcoal and ash into the Colorado River; the latter was larger with a stage approximately 5 m above base. Site visits following the floods found no fish in the mainstem of the creek, an almost totally denuded woody riparian zone, and channels severely altered with sequenced scour and fill reaches. The purpose of this study is to monitor the channel response following the fire and flood to determine when the system is appropriate for new humpback chub relocations and to determine the likelihood of future catastrophic events for the mainstem channel. Preliminary surveys indicate that the channel still retains substantial mineral fine sediment that have filled pools and fish refugia. The time required for channel stabilization will be evaluated through streamgage analysis, repeat cross-sections, pebble counts, repeat photography, and fine grained sediment mapping for the entire mainstem.

The Gold Belt Byway in south-central Colorado connects many sites of great historical and scientific significance that are discussed in the BLM's newest Junior Explorer book, Geology of the Gold Belt Byway. This book includes visits to the Florissant Fossil Beds National Monument, the mining district of Cripple Creek and Victor, fossil quarries in the Garden Park Area, a trace fossil site at Indian Springs, and the Royal Gorge of the Arkansas River. In visiting and reading about these locations, children will learn the geologic history of Colorado, and how geologists and paleontologists interpret the rock and fossil records to reconstruct that history. The target age group is between 8 and 12, although educational activities are included for students as young as 5. An emphasis is placed on reasoning and building vocabulary while catering to a variety of learning styles. Additionally, content is designed to address Colorado Department of Education Common Core Standards in Earth Science for grades 1 to 7. The book is a product of collaboration between the Geocorps America program, the Royal Gorge Field Office of the BLM, the National Park Service at Florissant Fossil Beds National Monument, and the Gold Belt Byway Association.

Bat fatalities can be reduced by altering turbine operations, but such curtailment decreases turbine efficiency. If additional ways of reducing bat fatalities at wind turbines were available such tradeoffs might not be needed. Based on the facts that bats perceive distant objects primarily through vision and can see in very dim lighting conditions, and the possibility that bats might interact with turbines after approaching them as they would trees, we propose a novel method of reducing bat activity at wind turbines: illumination of the structure with dim light. As a first step toward assessing this approach, we illuminated trees with dim flickering ultraviolet (UV) light in areas frequented by Hawaiian hoary bats Lasiurus cinereus semotus, an endangered subspecies affected by wind turbines. We used a repeated-measures design to quantify bat activity near trees with acoustic detectors and thermal video cameras in the presence and absence of UV illumination, while concurrently monitoring insect numbers. Results indicate that dim UV reduces bat activity despite an increase in insect numbers. Experimental treatment did not completely inhibit bat activity near trees, nor did all measures of bat activity show statistically significant differences due to high variance in bat activity among sites. However, the observed decreases in bat activity with dim UV illumination justify further testing of this method as a means to reduce bat fatalities at wind turbines.

Unfortunately, road managers choosing between dust control products often have little objective environmental information to aid their decisions. To address this information gap, the U.S. Geological Survey and the U.S. Fish and Wildlife Service collaborated on a field test of three dust control products with the objectives of (a) evaluating product performance under real-world conditions, (b) verifying the environmental safety of products identified as practically nontoxic in laboratory tests, and (c) testing the feasibility of several environmental monitoring techniques for use in dust control tests. In cooperation with refuge staff and product vendors, three products (one magnesium chloride plus binder, one cellulose, and one synthetic fluid plus binder) were applied in July 2012 to replicated road sections at the Hagerman National Wildlife Refuge in Texas. These sections were monitored periodically for 12 months after application. Product performance was assessed by mobile-mounted particulate-matter meters measuring production of fugitive dust and by observations of road conditions. Environmental safety was evaluated through on-site biological observations and leaching tests with samples of treated aggregate. All products reduced dust and improved surface condition during those 12 months. Planned environmental measurements were not always compatible with day-to-day refuge management actions; this incompatibility highlighted the need for flexible biological monitoring plans. As one of the first field tests of dust suppressants that explicitly incorporated biological endpoints, this effort provides valuable information for improving field tests and for developing laboratory or semifield alternatives.

The MMCO has been associated with an atmospheric CO (sub 2) pulse similar to levels anticipated in the next century, thus understanding MMCO climate may help inform predictions of future climate. To characterize the impact of the MMCO on the climate and ecology of the interior Pacific NW, we collected oxygen and carbon isotope compositions from fossil tooth enamel of rhino, equid, camel, and proboscidean. Most significantly, carbon isotopes in tooth enamel reflect delta (super 13) C values of plants consumed, which in return depends on atmospheric delta (super 13) C and mean annual precipitation (MAP). Thus, by analyzing tooth enamel delta (super 13) C and correcting for atmospheric delta (super 13) C, we can recover MAP through time. Sections investigated include the Oligocene John Day Formation (30-28 Ma), the Miocene Mascall (15.6 Ma), Quartz Basin (c. 15.5 Ma), Sucker Creek (15.0 Ma), Red Basin (c. 13.7 Ma), and Drewsey (10.0 Ma) Formations, and the Pliocene Glenns Ferry Formation (Hagerman; 3.3 Ma). Localities are in central or eastern Oregon except the Hagerman site in Idaho. Prior to the MMCO (John Day, c. 29 Ma), MAP in the interior Pacific NW was 440+ or -220 mm/yr. During the MMCO (Mascall, 15.6 Ma), MAP increased to 1050+ or -500 mm/yr. All later data (< or =15 Ma) show a decrease in MAP (125-300 mm/yr), implying arid conditions to the present. Oxygen isotopes are broadly constant through 10 Ma, implying no major changes in moisture source or upwind elevations (Cascade Ranges). Lower delta (super 18) O at Hagerman is consistent with increased distance from moisture sources and increasing elevations in the Cascade Range commencing c. 7 Ma. The increase in MAP during the high-CO (sub 2) MMCO is generally consistent with some but not all models of future climate in the region. A better understanding of the MMCO worldwide promises useful validation of model methods.

The majority of uses of this technique have occurred in surface environments and have produced valuable models for research and monitoring efforts. Few studies, however, have been completed in sub-surface environments, specifically caves. The National Park Service has been leading the efforts to adapt these methodologies for in-cave use. Grand Canyon National Park has over 335 known caves which contain significant remains of extinct Late Pleistocene fauna as well as substantial amounts of archaeological materials, including Middle to Late Archaic Split Twig Figurines. Within a national park setting, it is preferred to leave these materials in-situ, however documentation and monitoring is essential to ensure the preservation and protection of these resources. Here we present developing techniques for performing photogrammetry in the unique conditions of caves in order to improve our ability to document and monitor paleontological and archeological sites.

AN - 1780803343; 2016-032845 AB - New high-precision (super 10) Be CRN exposure analyses of boulders from distal cirque moraines in the Sierra Nevada present a conundrum: although all moraines are geomorphically fresh and unstable (mapped as Matthes age), some show young ages (last 150-300 yrs; late Little Ice Age--LIA) consistent with previous studies of Neoglaciation in the range, whereas other moraines show a majority of ages thousands of years older than LIA. Matthes moraines below the Lyell Glacier (Yosemite NP) show exposure ages consistently between 150-300 yr before 2015, whereas similar moraines below the adjacent Maclure Glacier have exposure ages ranging from 1900-3900 yr old. Boulders on correlative Matthes moraines to the north below Price Peak (west Lake Tahoe) have exposure ages ranging from 1900-9900 yr old; no boulders analyzed so far on these northern moraines show LIA ages. The abundance of pre-LIA exposure ages on many of these moraines seemingly contradicts both historical photographic evidence as well as geomorphic and lake-sediment evidence, which indicate that the most extensive Holocene glaciation in the Sierra Nevada was during the late LIA. Some ages, such as those below the Maclure Glacier, may reflect slow-flow dynamics associated with debris-covered glaciers (rock glaciers). The older ages below Price Peak, however, are more difficult to reconcile with previous records, particularly those indicating absence of glaciers in the Sierra before approximately 3500 cal yr BP. Consistency of the exposure ages implies that inheritance from prior exposure is unlikely to explain all the ages. Other possible explanations include deposition related to protalus processes or to discrete events (e.g., earthquake-induced rockfall); conversely, the ages may indicate that Holocene glaciation in the range was more spatially and temporally heterogeneous than previously thought. Additional exposure ages from these moraines and others farther south may help resolve this conundrum.

Here we evaluate GRACE TWS changes in the Colorado River Basin within the context of longer-term monitoring and modeling data to evaluate controls on water storage changes. The monitoring period (1980-2014) is generally characterized by decadal droughts (around 1990, early 2000s, and 2010s). Rates of TWS depletion during the droughts are generally similar ( approximately 6 km (super 3) /yr) totaling approximately 50-75 km (super 3) over drought periods of 2-6 years. However, the big difference between droughts since 2000 and earlier droughts is limited recovery because of only 1-2 anomalously wet years since 2000 versus approximately 4 years in the 1990s. GRACE data show slight recovery of TWS in 2005 and 2011 followed by large depletion of almost 47 km (super 3) over 2-3 yr. In the Upper Colorado River Basin TWS depletion is dominated by reservoir and soil moisture storage changes whereas in the Lower Colorado River Basin groundwater storage depletion is also important. The primary approach to managing these wet and dry climate extremes is through storing water, with current remaining reservoir storage representing approximately 3 years of water demand. Water management strategies adopted to cope with drought stress include conjunctive use of Colorado River water and groundwater and managed aquifer recharge in the Lower Colorado River Basin. While water allocations have been met to date, continued drought may jeopardize junior water rights and require more intensive drought-management strategies.

Yet, growth metrics can vary in form, and the justification for using one over another is rarely clear. We tested whether a growth index (GI) that scales the realized diameter growth rate against the potential diameter growth rate (PDGR) would give better estimates of mortality probability than other measures. We also tested whether PDGR, being a function of tree size, might better correlate with the baseline mortality probability than direct measurements of size such as diameter or basal area. Using a long-term dataset from the Sierra Nevada, California, U.S.A., as well as existing species-specific estimates of PDGR, we developed growth-mortality models for four common species. For three of the four species, models that included GI, PDGR, or a combination of GI and PDGR were substantially better than models without them. For the fourth species, the models including GI and PDGR performed roughly as well as a model that included only the diameter growth rate. Our results suggest that using PDGR can improve our ability to estimate tree survival probability. However, in the absence of PDGR estimates, the diameter growth rate was the best empirical predictor of mortality, in contrast to assumptions often made in the literature.Original Abstract: Le taux de croissance des arbres est frequemment utilise pour estimer la probabilite de mortalite. Cependant, les mesures de croissance peuvent prendre des formes variees et la justification pour utiliser l'une plutot que l'autre est rarement claire. Nous avons verifie si un indice de croissance (IC) qui met en rapport le taux de croissance en diametre realise et le taux de croissance en diametre potentiel (ICDP) donnerait de meilleures estimations de la probabilite de mortalite que d'autres mesures. Nous avons egalement teste si l'ICDP, qui est fonction de la taille de l'arbre, pourrait etre mieux correle avec une probabilite de mortalite de reference que des mesures directes de la taille, comme le diametre ou la surface terriere. A l'aide d'un ensemble de donnees a long terme provenant de la Sierra Nevada en Californie, aux Etats-Unis, ainsi qu'avec des estimations existantes de l'ICDP, specifiques aux especes, nous avons developpe des modeles de croissance et de mortalite pour quatre especes communes. Pour trois des quatre especes, les modeles qui incluaient l'IC, l'ICDP, ou une combinaison de l'IC et de l'ICDP etaient nettement meilleurs que les modeles n'incluant pas ces variables. Pour la quatrieme espece, le modele comprenant l'IC et l'ICDP s'est comporte a peu pres aussi bien qu'un modele utilisant le taux de croissance en diametre. Nos resultats indiquent que l'utilisation de la croissance potentielle peut ameliorer notre capacite a estimer la probabilite de survie des arbres. Toutefois, en l'absence d'estimations de la croissance potentielle, le taux de croissance en diametre est le meilleur predicteur empirique de mortalite, contrairement aux hypotheses souvent mentionnees dans la litterature.

This is especially relevant for sugar pine (Pinus lambertiana Douglas), a species experiencing population declines due to a suite of anthropogenic factors. Using data from an old-growth mixed-conifer forest in Sequoia National Park, we evaluated the effects of fire, tree size, prefire radial growth, and crown condition on postfire mortality. Models based only on tree size and measures of fire damage were compared with models that included tree size, fire damage, and prefire tree health (e.g., measures of prefire tree radial growth or crown condition). Immediately following the fire, the inclusion of different metrics of prefire tree health produced variable improvements over the models that included only tree size and measures of fire damage, as models that included measures of crown condition performed better than fire-only models, but models that included measures of prefire radial growth did not perform better. However, 5 years following the fire, sugar pine mortality was best predicted by models that included measures of both fire damage and prefire tree health, specifically, diameter at breast height (DBH, 1.37 m), crown scorch, 30-year mean growth, and the number of sharp declines in growth over a 30-year period. This suggests that factors that influence prefire tree health (e.g., drought, competition, pathogens, etc.) may partially determine postfire mortality, especially when accounting for delayed mortality following fire.Original Abstract: La mortalite des arbres est une composante essentielle de l'amenagement forestier dans le contexte des brulages diriges. Peu d'etudes ont cependant examine l'effet de l'etat de sante anterieur au feu sur la mortalite apres feu. Cela est particulierement pertinent dans le cas du pin a sucre (Pinus lambertiana Douglas), une espece dont la population connait un declin a cause d'une serie de facteurs anthropiques. A l'aide de donnees provenant d'une vieille foret melangee de coniferes dans le parc national Sequoia, nous avons evalue les effets du feu, de la taille des arbres, de la croissance radiale et de l'etat des cimes avant le feu sur la mortalite apres feu. Des modeles fondes uniquement sur la taille des arbres et des mesures des dommages causes par le feu ont ete compares a des modeles qui incluaient la taille des arbres, les dommages causes par le feu et l'etat de sante des arbres avant le feu (p. ex., des mesures de la croissance radiale et de l'etat de sante de la cime des arbres avant le feu). Immediatement apres un feu, l'inclusion de differentes mesures de l'etat de sante des arbres avant le feu a produit des ameliorations des variables comparativement aux modeles qui incluaient seulement la taille des arbres et des mesures des dommages causes par le feu. De meme, les modeles qui incluaient des mesures de l'etat des cimes ont mieux performe que les modeles qui incluaient seulement les dommages causes par le feu, mais ce n'etait pas le cas des modeles qui incluaient des mesures de croissance anterieures au feu. Cependant, 5 ans apres un feu les modeles qui predisaient le mieux la mortalite du pin a sucre incluaient des mesures des dommages causes par le feu et de l'etat de sante des arbres avant le feu, en particulier le DHP, le roussissement de la cime, la croissance moyenne sur 30 ans et le nombre de baisses marquees de croissance sur une periode de 30 ans. Cela indique que les facteurs qui influencent l'etat de sante avant un feu (tels que la secheresse, la competition, les agents pathogenes, etc.) peuvent en partie determiner la mortalite apres feu, surtout lorsqu'on tient compte de la mortalite differee a la suite d'un feu.

Groundwater levels and salinity are monitored in three observation wells in the park to detect long-term trends (years to decades). Data from these observation wells are useful for evaluating potential changes in groundwater conditions near the pools and ponds, which are commonly located adjacent to or within a few hundred meters of the coast. Analysis of continuous groundwater-level and salinity records from the observation wells revealed interesting and counter-intuitive dynamics within the highly permeable coastal groundwater system. Groundwater levels and specific conductance (a measurement of salinity) in the park fluctuate with the ocean tide and changes in air pressure. Of interest was the observation that peak salinity and peak groundwater levels do not occur simultaneously in individual wells. An unexpected phase advance in specific conductance relative to groundwater levels was observed in all three observation wells. The phase advance is a few hours in the wells. A simple analytical model of tidally influenced groundwater flow provides some insight into the phenomenon.

For years this method has been used to monitor vertical movement of the popular dunes in the park, some requiring the completion of a six mile hike with a 40-lb total station pack. This research compares the use of a lighter, more portable handheld Trimble GeoXH dGPS to a Nikon DTM-520 Total Station in measuring the vertical height of large dunes. Mapping grade dGPS units are known for their submeter horizontal accuracy, but lack the same dependability with measuring absolute vertical accuracy. The relative elevations they measure however, may be useful for measuring dune heights in the park. To further understand the relative vertical accuracy of the dGPS before assessing dunes, a series of measurements were used to monitor elevation drift in a fixed position over one hour in both cloudy and clear conditions. Results varied greatly based on atmospheric conditions, giving way to a better understanding of dGPS vertical accuracy in diverse weather situations. Following the fixed elevation tests, a multitude of dune heights were evaluated by collecting elevation data along the crests and bases using both the Nikon Total Station and Trimble dGPS. At the same site in which the total station's reflective rod was used to measure elevation, the dGPS was also employed to collect approximately 10 generic points to record elevation as well. The manual elevation measurements from base to crest taken with the total station and dGPS were further analyzed using GIS software and Lidar DEM Models. It was conclusive after taking the difference of the values recorded by the total station and dGPS that 10 out of the 11 dGPS measurements recorded were within one meter of the total station measurements despite variances in weather. Thus, the use of a handheld dGPS unit may be a sufficient and more portable option for measuring and tracking vertical dune migration at Great Sand Dunes National Park and Preserve.

However, the majority of the researchers with the expertise to collect, study, and curate those fossils work for universities and academic museums. Hence, collaborations among land managers, researchers, and museums are essential to protecting fossil resources. Such a collaboration has been particularly effective in Oregon, where the Bureau of Land Management, the National Park Service, private landowners and the University of Oregon have come together to pursue the study of the abundant terrestrial vertebrate record of Central Oregon. In recent years, many of our collecting efforts have focused in the Crooked River Basin, in an area of abundant fossils but with limited collecting history. The South Fork of the Crooked River exposes terrestrial sediments from Eocene to late Miocene age, similar to those that occur in the John Day Basin to the north. While the collecting history in the Crooked River Basin extends back more than 100 years, the fossils in this region remain understudied, and recent efforts by BLM and University of Oregon crews have uncovered a number of new sites that are changing our understanding of the area's environmental history. By involving geology field camp students in the research, the University of Oregon has provided the manpower to effectively survey and collect fossils over a wide area, as well as the expertise to describe and characterize both the fossils and the complex geology in which they occur. Several enthusiastic landowners have provided logistical support and access to deposits where the outcrop on private land. Our work over the last 5 years has shown the area to be a heterogeneous environment, producing a diverse fossil record that adds substantially to our knowledge of the Oregon Oligo-Miocene. In support of this project, the BLM has provided permits, data, and funding for dating and for curation. The John Day Fossil Beds National Monument has also proved an important collaborator, given their work in correlative sediments. The integration of the Crooked River section into our understanding of Oregon's geologic history is a great example of effective collaboration among federal land managers, researchers, and public museums.

The park's elevated topography and location downwind of the Ohio River Valley, where many acidic emissions to the atmosphere are generated, have made it a target for acid rain. Characterizing the link between air quality and water quality as related to acid rain, contaminants, soil conditions, and forest health is a high priority for research and monitoring in SNP. Shenandoah National Park natural resource managers showed abundant foresight by implementing an aquatic biota monitoring program well before SNP became a National Park Service Prototype Inventory and Monitoring Park in the early 1990's. As a result of three different monitoring programs, a combined record of over three decades of data on water quality and biota in SNP cold-water riverine systems exists. Although the objectives of the programs differ, the common element that unites the three is water resources, therefore, some of the same water-quality parameters were collected for each effort. Inconsistent overlap among the three programs, however, resulted in spatially and temporally disparate data. The objective of the study was to integrate, analyze, and interpret the data to identify trends in stream-water quality and relations between aquatic fauna and stream-water chemistry. In general, stream-water quality and accompanying aquatic fauna were related to the underlying bedrock geology of the watersheds; the best stream-water quality and the healthiest communities of macroinvertebrates were found in streams underlain by bedrock that had the highest acid-neutralizing capacity. In contrast, stream water with lower pH and a depauperate macroinvertebrate community were underlain by bedrock with poor acid-neutralizing capacity.

Currently, the park relies exclusively on water from Roaring Spring (RS). RS supplies nearly 50% of the flow of Bright Angel Creek (BAC), a stream system that has been the focus of an invasive species removal project in order to restore native, threatened and endangered fish populations. Additionally, excess water from the transcanyon pipeline is discharged into Garden Creek (GC), the pumping transfer station, creating elevated flow between Indian Garden and the confluence with the Colorado River. We conducted an assessment of the potential impact of discontinuing diversion from the spring; particularly on hydrologic and aquatic resources of two tributaries of the Colorado River. Stream flow and water chemistry were taken at cross sections along the two tributaries. Daily averages of continuous flow and temperature were used for deterministic (energy budget) modeling to assess the effects of an altered thermal regime on BAC. Invertebrate sampling was conducted to evaluate community structure and diversity. Using PHABSIM software, habitat availability models for current and altered flow regimes were constructed in BAC and GC to assess the effects a change in flow would have on fish and invertebrate structure and diversity. Habitat modeling suggests that an increase in discharge toward the historical flow regime would increase habitat for invasive fish in BAC. Aquatic habitat would be significantly decreased for all species in GC and could result in a drop in diversity for macroinvertebrates. Thermal modeling suggests a high correlation between surface water and air temperature, with the effect of increased spring discharge on BAC being most significant within the first mile downstream of spring water input. These results will be used to help the Park make informed decisions adjusting water supply operations.

These 245 million acres are managed to safeguard priceless resources spanning billions of years and are among the world's best outdoor laboratories for the study of paleontology. In 2009, Congress passed the Omnibus Public Land Management Act that includes the Paleontological Resources Preservation subtitle (PRPA), which provides land managing agencies the clear authority to manage paleontological resources on public lands as natural and irreplaceable parts of America's heritage. This is accomplished by proper documentation, collection, preparation, and curation of paleontological resources. PRPA defines paleontological resources as any fossilized remains, traces, or imprints of organisms, preserved in or on the earth's crust, that are of paleontological interest and that provide information about the history of life on earth. PRPA allows the public to hobby collect common invertebrate and plant fossils without a permit. However, scientific documentation and/or collection of any fossil (i.e., vertebrate, invertebrate, plant, or trace) from BLM-administered land require a Paleontological Resources Use Permit. These resources and the associated information remain the property of the United States and are preserved for the public in approved repositories, where they are available for scientific research and public education. Permits are required so that BLM can document, monitor, and manage paleontological resources using scientific principles and expertise. Individuals conducting research or educational studies on BLM paleontological resources should contact the BLM prior to undertaking these activities. Likewise, any consumptive analyses (e.g., coring, thin sectioning) or duplication (molding and casting) of public paleontological resources (whether done in the field or lab) often requires BLM authorization. In partnership with BLM permittees, programs are being developed to increase public awareness about the significance of paleontological resources, and to highlight the world-class fossils from public lands that are pivotal to our understanding of life on our planet and upon which many concepts related to evolution and environmental change are based.

The Act furthers this important goal by directing the Departments of Agriculture and the Interior to: (1) use a permit system for the collection of paleontological resources from Federal land, (2) ensure that the resources that were collected under a permit are deposited into approved repositories, (3) protect the confidentiality of specific locality information, (4) manage and protect paleontological resources on the lands that they administer using scientific principles and expertise, (5) develop plans for inventories, monitoring, and scientific and educational use, (6) establish a program to increase public awareness about the significance of paleontological resources, and (7) allow casual collection of common invertebrate and plant fossils on BLM, Forest Service and Bureau of Reclamation lands where consistent with the other laws governing those lands. The Act then directs the Department of Agriculture and the Interior to issue regulations. While the Department of Agriculture regulations are already finalized, the Department of the Interior regulations (which will apply to the Bureau of Land Management, National Park Service, Fish and Wildlife Service, and Bureau of Reclamation) are still under development. This presentation will focus on the Act and regulations as applicable to the DOI bureaus. It will describe which provisions of the Act contain new requirements for the DOI bureaus, and which provisions reiterate and consolidate existing requirements. In addition, this presentation will update attendees on the status of the DOI regulations. Attendee input will be welcomed on how the DOI bureaus and stakeholders can work together and collaboratively in the implementation of the Act and the DOI regulations.

These efforts include a touchscreen kiosk in the Visitors Center to greatly expand the amount of information available to visitors. The kiosk allows users to choose content, with several different topics and levels of interaction. For example, due to size limitations, security concerns, and fossil fragility, visitors are rarely permitted into the research area. Using the kiosk, visitors will be led on a virtual tour, learning about the different sections of the laboratory through short video clips, with the option to "access" other areas of the lab for more in-depth information. This will be coupled with live virtual tours using a GoPro camera with instantaneous wireless video streamed to the theater. Additionally, the monument is developing content for an augmented reality application (AR app) for smartphones and tablets which will be used in conjunction with the wayside exhibits along our trails. The app has the ability to "recognize" any wayside through the device's camera and then deliver specialized content to the user. This content can be any type of media: photos, videos, audio, and animations. For example, we are developing a walking tour with the monument's paleontologist for those visitors who prefer a more science-focused experience. In the future, content for students could be generated that conforms to Next Generation Science Standards, providing a valuable resource to K-12 teachers. Parks like FLFO, where science and natural history are the primary focus, can particularly benefit from these new media resources. There is much more information about the park than can be presented using the available exhibit space or waysides. Digital resources are not limited by space, and can provided the maximum amount of content tailored to each visitor. As new scientific discoveries are made about the paleontology of the monument, the content in the kiosk and AR app can be updated so that the science presented to the visitor is as accurate and current as possible. Utilizing these digital avenues of content delivery will allow the park to remain relevant and informative to all visitors as our understanding of the science grows and expands.

UCMP has a web-accessible collections database (http://ucmpdb.berkeley.edu/) containing data on over 110,000 localities and almost 400,000 individual specimens. The database displays only county-level data to the public in accord with federal regulations and by the request of private landholders. Specific geographic information is available to researchers upon request. In 2014, programmers at UCMP created a portal into the UCMP database for selected NPS staff to view geographic data about the fossil localities and specimens collected within their current administrative boundaries. In order to populate the portal, georeferenced localities from each state were viewed through Berkeley Mapper (http://berkeleymapper.berkeley.edu/) and compared with NPS boundaries as displayed in Google Maps. The NPS portal now contains data on over 900 localities and 14,000+ specimens. Providing this data to NPS staff will improve the management of paleontological resources by allowing parks to relocate historic localities, establish field monitoring programs and mitigate any impacts on fossils during construction projects. UCMP and UC Berkeley have partnered with federal agencies for over a century, including advocating for the establishment of several NPS areas, including John Day Fossil Beds National Monument and Florissant Fossil Beds National Monument. This portal has increased collaboration between UCMP and NPS staff, resulting in more accurate data and an increased awareness on both sides of paleontological resources on federal lands. As data can easily be added to the portal, it will also help UCMP respond to future requests for information, to the benefit of the management of fossil resources.

TDA Cockerell, one of the founders of the University of Colorado's Museum of Natural History, spent much of his career describing the rich fossil insect assemblage found in the lacustrine shale beds that would eventually become the heart of the Florissant Fossil Beds National Monument. Over one hundred years later, the two institutions have a partnership that is even stronger than ever. Central to this partnership are the significant paleontological resources that originate from the Florissant Formation and the common mission that the National Park Service and University of Colorado share, which include the preservation of natural resources/collections and the importance of education and outreach. There are over 1,600 insect and plant species described from the late Eocene Florissant Formation. Significant collections, including important holotype and figured specimens, are housed at the University of Colorado. Data sharing and exchange of information regarding curatorial best practices are frequent between the institutions. Collaboration on digitization, imaging and accessibility has further facilitated curation, documentation and increased accessibility to specimens and associated data for researchers, educators and the public. Working together and in partnership with other institutions has led to a diverse community of Florissant researchers who study history, biodiversity, geochemistry, sedimentology and stratigraphy, paleoecology, taphonomic processes, and climate change. Education and outreach efforts have been focused on presentations and seminars for public audiences, permanent and temporary exhibits at both locations, the development and implementation of K12 teacher training programs, Florissant's highly successful internship program and the CU Museum's graduate program in Museum and Field Studies. Thus, continued strong collaboration between the University of Colorado and the Florissant Fossil beds in paleontological resource management, research and education/outreach has allowed both to accomplish more together than either could have accomplished alone.

Debris flows and landslides are relevant to everyone from road crews to real estate agents, but the number of driving factors involved in understanding and predicting them can be dizzying--especially with the added variable of frozen ground. In Alaska and similar high-latitude climates this is becoming a persistent problem. Following a massive debris slide in October, 2013, Geocorps and Denali National Park and Preserve provided the opportunity for a Geohazards Specialist to assist in mass movement inventorying, monitoring, and mitigation planning. In the first year, this led to the development of a catalog, maps, and risk analyses based on known mass movement events in the park, geohazard education and outreach programs, publishing of a publicly available educational fact sheet, presentation of risk analyses and mitigation plans at a regional geotechnical conference, and extensive discussion to determine the needs and capabilities of a park monitoring program. The second year provided an opportunity to build on the work of the first, as well as work with other federal agencies to develop an inter-agency, nation-wide Unstable Slope Management Program, develop and implement an interpretation scheme based around natural hazards, and explore more remote hazards for integration into existing databases. Though some variables are still not well-constrained, valuable advances have been made in beginning to determine the origin, cause, and potential effects of mass movements along the park road corridor. These combined efforts and experiences demonstrate a thorough commitment to furthering the respective missions of the National Park Service and the Geological Society of America by serving both science and the users of our National Parks.

The complex provides the largest source of potable water in Death Valley, and has long been the center of human development--all of the springs in the complex have been developed or altered since the mid-1800s. Discharge from three springs was diverted to provide domestic water for Furnace Creek until 2009, when the National Park Service (NPS) brought online three new pumping wells and began a long-term restoration of the Travertine Springs complex. This restoration offers an exceptional scientific opportunity to examine the physical, biogeochemical, and ecological processes that govern desert spring ecosystems. Prior to restoration work, NPS and research partners performed vegetation inventories, surface and groundwater hydrologic measurements, and benthic macroinvertebrate (BMI) surveys within the springs complex. After the production wells were placed online, a fire burned much of the vegetation in the springs complex, including a large fraction of the non-native palm trees. NPS took that opportunity to remove more than 500 palms in the winter of 2011, and began to incrementally reverse the diversions of flow from Travertine No. 2 (one of the springs that had been diverted for water supply). A fraction of the previously diverted discharge is expressed as surface flow below Travertine No. 2, with the remainder contributing to groundwater recharge and increased flows in the downgradient springs. Current monitoring efforts include BMI surveys in the restored channel and soil moisture monitoring, as well as a number of observation wells sunk into the shallow groundwater. Once the restored communities have been established in Travertine No. 2, existing structures in Travertine No. 1 will be removed, returning flow to its natural channel. Future work in the Travertine Springs complex will offer continuing opportunities for both restoration and research.

The history of discovery, collection, research and management of paleontological resources from areas that are managed today by the National Park Service (NPS) dates back to the late 17th century. Government and military surveys of the American west, including those lead by Ferdinand Hayden into Yellowstone and John Wesley Powell on the Colorado River, resulted in some of the earliest collections of fossils from areas now administered by the NPS. More than 170 museum repositories across the United States and in a few foreign countries manage over 600,000 fossil specimens associated with the U.S. national parks. A large number of these fossils were collected by U.S. Geological Survey staff conducting geologic field research and mapping projects. A wealth of unpublished data on paleontological localities and specimens are contained in USGS Evaluation Reports (E&R) that were initiated in the late nineteenth century. The preservation of data associated with NPS localities is an important role for the various federal and other museum repositories, to ensure the scientific and education values of NPS fossils is available for researchers, the public and for park managers.

Sharing ideas between sites having common themes is an important aspect to consider when developing geoheritage strategies. Such cooperation enables conservation efforts, development of local economies, and education and outreach activities. Florissant Fossil Beds National Monument in Colorado features world-renowned petrified trees and shares its research and conservation expertise with other petrified forest sites in Peru and Thailand. All of these sites have aspired to achieve Geopark designations. The Monument engages in a "sister park" partnership with El Bosque Petrificado Piedra Chamana in Peru, which is enabled by an agreement between The Friends of the Florissant Fossil Beds and the comparable nonprofit organization in Peru. This interaction has provided a complete site inventory and ongoing paleontological research in Peru, as well as hosting participants from Peru to visit Florissant. The broader scope of these interactions is developing into multinational partnerships, and some of the common issues were shared during the Workshop on Petrified Wood Conservation in Thailand in August 2014. As a consequence, new concepts for networking are currently developing between sites in Colorado, Thailand, Peru, and Greece. Moving from one-to-one "sister park" relationships to broader, thematically-shared "family park" networks of sites with similar geoheritage assets and conservation concerns holds potential for sharing mutually beneficial ideas across international boundaries. The scope of such networks can extend beyond "sites with boundaries" to also include other institutions involved with geoheritage, research and conservation of petrified forests.

The study measures the effects of bison on the soil surrounding grazing locations, the water quality of springs and sinks holes bison use, species richness of vegetation in the areas, and species richness of herpetofauna if present. This study will occur on the North Rim of Grand Canyon National Park at 80 site locations based on a stratified random sampling of sinkholes used by bison and sinkholes with no documented evidence of bison use. The variables tested in this study will be: infiltration capacity, presence of E.coli, inventory of species of vegetation, and habitat assessment for herpetofauna. This data will then be applied to the groundwater models of the canyon to determine the larger effects of the bison. This study will quantify the ecological impacts of the bison on the North Rim and influence future management decisions.

The formation has a reported radiometric age of 34.07 Ma that corresponds to the cusp of the Eocene-Oligocene boundary.The nonmarine ostracode fauna were first reported and described in 1910 without illustration, and since then no significant study has been performed to further confirm the taxa present in the formation. Samples of fossiliferous mudstone were excavated out of the upper shale unit of the Florissant Formation in relative proximity to the type locality of the reported ostracodes. Exceptional specimens were chosen from the processed residue and evaluated on a Hitachi 3400S Variable-Pressure Scanning Electron Microscope. Our evaluation of carapace size, shape, adductor muscle scars, and the nature of the duplicature confirms the species as valid. On the basis of external and internal characteristics, we recommend Cypris florissantensis Cockerell be reassigned to a more appropriate genus within the Family Cyprididae. We further report the presence of previously undocumented species Candona artesensis Swain. Closely related taxa, including those of genera Heterocypris and Candona, have been reported from the coeval deposits of the early Eocene Green River Formation which spans across Colorado, Utah, and Wyoming, and the Middle Eocene Brian Head Formation in Utah. The occurrence of this ostracod fauna in the upper shale unit suggests the paleoecology of the later generation of Lake Florissant recovered after the prior deposition of volcanic lahars from the nearby Guffey Volcano complex. Moreover, the abundance of cypridid instars suggests an in-situ biocoenosis; the comparative lack of Candona instars indicates the cypridid assemblage would be the most suitable paleoecological indicator for future studies on Lake Florissant.

The National Park Service (NPS) Geologic Resources Division (GRD) recently has led an effort to formally establish the principles of, and a program to support, America's geologic heritage. Preserving geologic features has been a part of the NPS since its inception in 1916 and notably includes the establishment of the National Natural Landmarks program in 1962. GRD has supported cave and karst and paleontology programs since the 1990s and in 2011 created a Geologic Heritage Program to more systematically address issues related to geologic heritage features, including arches, dunes, volcanoes, and geothermal. In March 2013, GRD co-convened an invitational workshop on America's Geologic Heritage with the U.S. National Committee for the International Union of Geological Sciences, Geological Society of America, American Geosciences Institute, Colorado Geological Survey, and U.S. Geological Survey. See http://go.nps.gov/americasgeologicheritage for more about the workshop and geologic heritage concepts. In 2015, as a follow-up to the workshop, GRD and American Geosciences Institute published America's Geologic Heritage: An Invitation to Leadership that outlines the following principles of America's geologic heritage: 1) America's geologic landscape is an integral part of our history and cultural identity, and we have a proud tradition of exploring and preserving our geologic heritage; 2) America's geologic heritage, as shaped by geologic processes over billions of years, is diverse and extensive; 3) America's geologic heritage holds abundant values-aesthetic, artistic, cultural, ecological, economic, educational, recreational, and scientific-for all Americans; 4) America's geologic heritage benefits from established conservation methods developed around the world and within the United States; and 5) America's geologic heritage engages many communities, and your involvement will ensure its conservation for future generations.

It includes paleontological sites of international historic and scientific importance such as the Garden Park National Natural Landmark, Florissant Fossil Beds National Monument, and Indian Springs Trace Fossil National Natural Landmark. The area also includes significant stories about the gold mining history of Colorado at Cripple Creek and early oil and gas exploration near Florence. Scenic sites such as the Royal Gorge and Skyline Drive expose vast rock sections. The area is managed by the Bureau of Land Management (BLM), the National Park Service (NPS), local city governments, and private land owners including a large gold mining company. In response to interest from NPS to propose sites within the United States that could potentially join the UNESCO Geopark network, NPS and BLM collaborated in 2010 to prepare a proposal to move forward a nomination for designating the Gold Belt GeoPark. GSA GeoCorps interns assisted these agencies to examine and map sites along the route and evaluate geologic assets relevant to the concept of geoheritage, and drafted a letter of proposal. As the US involvement in GeoParks became unrealistic due to geopolitical reasons, the proposal became one of the models in an alternative effort that is still ongoing to establish a plan for a national geoheritage program. The primary challenges faced are to keep the proposal active and to garner more support from local communities to embrace the concept and envision the economic benefits. Renewed interest in establishing a national geoheritage program and the establishment of a U.S. Geoparks National Committee will add additional impetus to further refine and develop the concept of a Gold Belt Byway National Geopark.

Two primary decision analysis methods, multicriteria decision analysis and the expected value of information, were used to evaluate the alternative strategies against the resource goals and to evaluate the influence of uncertainty. A total of 18 performance metrics associated with 8 out of 12 resource goals (fundamental objectives) were developed by the Bureau of Reclamation and National Park Service in partnership with subject-matter teams composed of Federal, State, tribal, and private experts. A total of 19 long-term strategies associated with 7 alternatives were developed by the Bureau of Reclamation, National Park Service, Argonne National Laboratory, U.S. Geological Survey, and Cooperating Agencies. The 19 long-term strategies were evaluated against the 18 performance metrics using a series of coupled simulation models, taking into account the effects of several important sources of uncertainty. A total of 27 Federal, State, tribal, and nongovernmental agencies were invited by the Assistant Secretary of Interior to participate in a swing-weighting exercise to understand the range of perspectives about how to place relative value on the resource goals and performance metrics; 14 of the 27 chose to participate. The results of the swing-weighting exercise were combined with the evaluation of the alternatives to complete a multicriteria decision analysis. The effects of uncertainty on the ranking of long-term strategies were evaluated through calculation of the value of information. The alternatives and their long-term strategies differed across performance metrics, producing unavoidable tradeoffs; thus, there was no long-term strategy that was dominated by another across all performance metrics. When the performance of each alternative was weighted across performance metrics, three alternatives (B, D, and G) were top-ranked depending on the set of weights proposed: Alternative B was favored by those stakeholders that placed a high value on hydropower; Alternative G was favored by those stakeholders that placed a high value on the restoration of natural processes, like beachbuilding and natural vegetation; and Alternative D was favored by the remaining stakeholders. Surprisingly, these rankings were not sensitive to the critical uncertainties that were evaluated; that is, the choice of a preferred long-term strategy was sensitive to the value-based judgment about how to place relative weight on the resource goals but was not sensitive to the uncertainties in the system dynamics that were evaluated in this analysis. The one area of uncertainty that did slightly affect the ranking of alternatives was the long-term pattern of hydrological input; because of this sensitivity, some attention to the possible effects of climate change is warranted.

The goal of the GRI is to increase understanding of the geologic processes at work in parks and provide accurate geologic information for use in park decision-making. The GRI program is a partnership between the NPS and Colorado State University (CSU), and relies heavily upon the U.S. Geological Survey, individual state geological surveys, and other organizations in developing its source map products. The GRI produces several products to assist park management and staff in the management and protection of their park. The first product is a digital geologic-GIS map product that is available in three data formats: 1.) an ESRI 10.X file geodatabase and accompanying 10.0 ArcMap document for use with ESRI ArcGIS software, 2.) KML/KMZ file for use with Google Earth, and 3.) an ESRI 10.2 map service for use with ESRI online web map applications such as ArcGIS Online, or other portal/viewer applications. In addition to the geologic-GIS data the GRI also produces a basic cartographic layout and a geologic report. The layout displays a park's geologic map complete with prominent features and localities within and around the park. The report is a comprehensive document that presents a park unit's: 1.) geologic significance, 2.) geologic history, and 3.) discusses prominent geologic features, processes and issues, and presents this in a scientific format directed at park resource managers. This poster showcases GRI products produced for NPS parks in the state of Utah. For each Utah park a single completed GRI product is presented. Also presented is a list of all available GRI products for each Utah park.

One hundred years later, Dinosaur National Monument is taking steps to bring Carnegie Quarry to everyone around the world, through an interactive website. The Digital Quarry Project is a work-in-progress, multi-year project with a unique approach to digitizing and publishing Carnegie Quarry data that is accessible anywhere, anytime and by anyone. The Digital Quarry Project has implemented a multitude of tools to bring the project to life, including: iPad apps for document digitization, digital cameras, Adobe design tools, web hosting and database services, content management systems, and a suite of programming and markup languages. Collaboration on the Digital Quarry Project has occurred between monument staff, volunteers, university faculty and students to facilitate the website's inception. A prototype website developed during the summer of 2015 serves as the model for expanding the site to include the entire modern and historic Carnegie Quarry. A comprehensive overview of the technologies used will allow similar digitization projects around the world to easily adopt the Digital Quarry Project's architecture.

We used a chronosequence of vessel grounding disturbances of different ages (0 yr, 1 yr, 3 yr, 4 yr, 5+ yr) as a model for soil disturbance to test hypotheses that disturbance alters primary producer communities, soil properties, biogeochemical processes, and infauna communities in seagrass ecosystems and that altered structure and processes will change following disturbance through seagrass bed development and ecosystem recovery. Disturbance involving excavated surface soils resulted in long-term loss of seagrass and macroalgae and stored organic carbon, nitrogen, and phosphorus. Disturbed sites were characterized by reductions in variables related to organic matter and inorganic nutrient content. Disturbance altered habitat quality for some taxa including amphipods, as evident from differences in invertebrate community structure. These impacts persisted in study sites for 5+ yr after the disturbance, likely because of physical and chemical soil modification accompanied by slow development of the seagrass community. We estimate that disturbance from 0.4 m deep excavations led to losses of 6.0 kg m super(-2) organic C (C sub(org)), 0.4 kg m super(-2) N, and 0.03 kg m super(-2) P from the disturbed areas. First-order conservative estimates of scarring excavation rate in Miami-Dade County, Florida, USA, suggest potential annual fluxes of 1.1 x 10 super(6) kg C sub(org), 74000 kg N, and 5500 kg P from seagrass soils in the region. Our findings suggest that vessel grounding disturbances create complex and long-term resource losses that are undervalued by resource trustees.

Isotopic analysis of vibrissae (whiskers) is a potentially useful approach to resolving the nutritional ecology of this species because long-term (up to 8 yr) dietary information is sequentially recorded and metabolically inert once formed. Additionally, vibrissae are grown in utero, potentially offering indirect inference on maternal diet. However, diet reconstruction using isotopic techniques requires a priori knowledge of trophic enrichment factors (TEFs), which can vary relative to diet quality and among animal species. In this study, we provide new TEF estimates for (1) maternal relative to pup vibrissae during both gestation and nursing and (2) adult vibrissae relative to a complex diet. Further, we refine vibrissa-milk TEFs based on an additional 76 animals with an age distribution ranging from 1 to 20 mo. Mother-pup vibrissae TEF values during gestation and nursing were near zero for delta super(13)C and averaged 0.8 and 1.6[perthousand], respectively, for delta super(15)N. In contrast, vibrissa-fish/invertebrate TEFs averaged 3.3 (+ or - 0.3 SD) and 3.7[perthousand] (+ or -0.3) for lipid-free delta super(13)C and delta super(15)N, respectively. Average lipid-free delta super(13)C and delta super(15)N vibrissa-milk TEFs were 2.5 (+ or -0.9) and 1.8[perthousand] (+ or -0.8), respectively, and did not differ among metapopulations. Empirically determined TEFs are critical for accurate retrospective diet modeling, particularly for evaluating the hypothesis of nutritional deficiency contributing to the lack of Steller sea lion population recovery in some regions of Alaska.

If otolith delta super(13)C values reflect diet, isotope values from recent otolith and muscle tissue should correlate and known ontogenetic diet shifts should be reflected in comparisons between otolith material deposited during different life history stages. We analyzed paired otolith and muscle samples for delta super(13)C from black rockfish Sebastes melanops to examine the potential of otoliths to reflect diet in small (200-299 mm fork length) and large (> or =300 mm) fish. We found a significant positive regression between delta super(13)C values from recent (~12 mo) otolith material and muscle in large fish, but not in small fish. Within individual otoliths, delta super(13)C values were enriched by ~3[perthousand] in recent otolith edge material compared to age-0 otolith core material and were consistent with known nearshore-offshore gradients in delta super(13)C values at the base of the food web. Bulk otolith delta super(13)C appeared to provide a broad indicator of dietary carbon sources, but variation in metabolism and dissolved inorganic carbon delta super(13)C among and within individuals likely influences otolith delta super(13)C as well and limits precision. Nevertheless, the results are promising and bulk otolith delta super(13)C may be an appropriate tool to examine large trophic and ecosystem level shifts that have occurred concurrently with changes in habitat, commercial fishing, invasive species, climate change, and other direct or indirect human impacts using historic or ancient otoliths. Future studies should continue to consider the utility of bulk otolith delta super(13)C to describe diet in other marine fish using this simple approach.

Here, we provide a survey of the behavioral responses of reproductive male and female lake trout (Salvelinus namaycush) to natural conspecific chemosensory stimuli. A flow-through laboratory assay with side-by-side artificial spawning reefs was used to evaluate behavioral preferences of spawning-phase males and females for chemosensory stimuli from juveniles and from spawning-phase males and females. Males and females preferred male and juvenile stimuli over no stimuli, but only had weak preferences for female stimuli. Only females had a preference for male over juvenile stimuli when given a direct choice between the two. The unexpected observation of male attraction to male stimuli, even when offered female stimuli, indicates a fundamental difference from the existing models of chemical communication in fishes. We discuss our results from the perspectives of prespawning aggregation, mate evaluation, and spawning synchronization. Identification of specific components of the stimuli will allow confirmation of the function and may have management implications for native and invasive populations of lake trout that are ecologically and economically important.Original Abstract: S'il a ete postule que la chimioreception influencerait le choix des sites de frai, la recherche d'un compagnon et la synchronisation de la liberation de gametes chez les ombles (Salvelinus spp.), peu de preuves comportementales appuient ces postulats. Nous presentons une evaluation des reactions comportementales de touladis (Salvelinus namaycush) males et femelles reproducteurs a des stimuli chimiosensoriels naturels provenant de conspecifiques. Un essai en ecoulement continu en laboratoire avec des recifs de frai artificiels contigus a ete utilise pour evaluer les preferences comportementales de males et femelles en phase de frai pour des stimuli chimiosensoriels provenant de juveniles et de males et femelles en phase de frai. Les males et les femelles preferaient les stimuli des males et des juveniles a l'absence de stimulus, mais ne presentaient que de faibles preferences pour les stimuli des femelles. Seules les femelles avaient une preference pour les stimuli des males plutot que des juveniles quand elles etaient en presence d'un choix direct entre les deux. L'observation non prevue d'une attraction exercee par les stimuli de males sur les males, meme en presence de stimuli de femelles, indique une divergence fondamentale par rapport aux modeles existants deja de communication chimique chez les poissons. Nous discutons de nos resultats des points de vue du regroupement avant le frai, de l'evaluation des compagnons et de la synchronisation du frai. L'identification de composantes specifiques des stimuli permettra d'en confirmer la fonction et pourrait s'averer pertinente pour la gestion de populations de touladis indigenes et envahissantes d'importance ecologique et economique.

This stream has been selected for the reintroduction of native fish species; variability in habitat conditions play a major role in the viability of these reintroduction efforts. This study quantifies the variability of flow and documents the relationship between available unconsolidated deposits, and discharge variability. We measured discharge at thirteen sites, using standard methods, in order to assess where water was being lost to the surrounding gravels. The overall surface areas of gravel deposits between sites were calculated using GIS software. During high flow periods, sites showed decreased discharge in areas that contained a greater area of gravel bars, indicating higher infiltration rates and increased recharge through the hyporheic zone into the gravels in these sections of the creek. Low flow periods showed an overall increase in discharge from the gravels and a different relationship, likely related to individual aquifer characteristics. The dynamics of this hyporheic exchange acts as a mechanism for habitat protection in the regulation of baseflow. Without these gravel bars, the habitat would have higher high flow events and a lower baseflow, negatively impacting habitat stability for native fish species.

Its largest bone, the stylohyal, is the most frequently found as an isolated element. It is known for some species of Pleistocene ground sloths (Megalonyx jeffersonii, Megatherium americanum, Paramylodon harlani, Nothrotheriops shastensis, Glossotherium robustum and Scelidotherium leptocephalum) but not for the largest mylodontid Lestodon armatus. Here we describe a right stylohyal found in the late Pleistocene megafaunal bonebed of the Arroyo del Vizcaino site, Uruguay, as two perfectly matched pieces that were within a few centimeters of each other. A small notch, possibly a conchoidal flaked perimortem fracture, is observed in the lateral face. The specimen, whose general form is a sinusoid cylinder with the proximal end expanded and compressed, must have belonged to a juvenile individual, since it lacks both the distal and proximal surfaces that articulate with the skull and the epihyal, respectively. Instead, both ends show an irregular surface as those seen in the contact with the growth cartilage. Additionally, its maximum length is 105 mm, larger than the equivalent part of the stylohyal of adult Glossotherium. At the expanded proximal end that articulates with the skull the large fossa found in Glossotherium and Scelidotherium cannot be observed, which could be due to a taxonomic difference, to the stage of growth or both of them. The bone shows marks, several interpreted as caused by trampling and at least one with features as those left by human tools.

In the face of climate change (predicted increases in aridity and a shift from snow to rain), increased development, and potential contamination, it is essential to characterize the aquifer in order to both conserve downstream aquatic and riparian ecosystems and to manage the park's water supply. Additionally, estimating the storage capacity of the aquifer allows the park to begin adjudication processes to claim and protect its water, ensuring better protection of the Canyon's ecological resources. To better understand the capacity, retention time, and flow paths of the aquifer we conducted hydrograph analyses, including recession analyses and hydrograph separations, and performed the first dye trace study in Grand Canyon National Park. Hydrograph analyses of 2013 and 2014 data show an approximate 18 percent reduction in both total annual discharge and total baseflow storage between 2013 (a dry year with winter snowpack) and 2014 (a dry year with minimal snowpack). However, baseflow recession slopes remains constant between years. Hydrograph separations show an initial piston flow pulse dominating early snowmelt while direct flow dominates remaining snowmelt input. These results indicate that increasing aridity reduces aquifer storage and show a relatively short retention time within the aquifer system. These trends suggest that this aquifer and associated downstream ecosystem may be vulnerable to significant reduction in flow in the face of climate change JF - Abstracts with Programs - Geological Society of America AU - Hoffman, Claire AU - Tobin, Benjamin W AU - Valle, Cynthia M AU - Childres, Hampton AU - Gandee, Michele N AU - Schenk, Edward R AU - Anonymous Y1 - 2015 PY - 2015 DA - 2015 SP - 116 PB - Geological Society of America (GSA), Boulder, CO VL - 47 IS - 7 SN - 0016-7592, 0016-7592 KW - 21:Hydrogeology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1765870551?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Abstracts+with+Programs+-+Geological+Society+of+America&rft.atitle=Modeling+the+water+supply+of+Grand+Canyon+National+Park%3B+the+effect+of+climate+change+on+a+karstic+aquifer&rft.au=Hoffman%2C+Claire%3BTobin%2C+Benjamin+W%3BValle%2C+Cynthia+M%3BChildres%2C+Hampton%3BGandee%2C+Michele+N%3BSchenk%2C+Edward+R%3BAnonymous&rft.aulast=Hoffman&rft.aufirst=Claire&rft.date=2015-01-01&rft.volume=47&rft.issue=7&rft.spage=116&rft.isbn=&rft.btitle=&rft.title=Abstracts+with+Programs+-+Geological+Society+of+America&rft.issn=00167592&rft_id=info:doi/ LA - English DB - GeoRef N1 - Conference title - Geological Society of America, 2015 annual meeting & exposition N1 - Copyright - GeoRef, Copyright 2016, American Geosciences Institute.

Additionally, many standard hydrogeologic methodologies are often not allowed when these areas are managed as wilderness. Here, we assess the value of two methods to categorize remote karst springs into grouping for long term monitoring of a small number of select springs: a geomorphic method and a hydrochemical method. The first of these methods is derived from Springer et al. (2008) and groups springs based on morphological features while the second uses major ion data, field water quality, and discharge data to group springs within a multivariate statistical framework. Using springs from Sequoia and Kings Canyon National Parks, in California, and Grand Canyon National Park, in Arizona, both methods were used to group springs and then the intra- and intergroup variability of aquifer behavior and associated ecosystems were assessed to determine the ability of these methods to differentiate between spring characteristics. Results suggest that the two methods provide distinctly different groupings: the hydrochemical method separates springs into groups with similar aquifer characteristics while the geomorphic categorization separates springs into groups with similar aquatic habitats. For long-term monitoring efforts, both of these methods provide a good means of reducing the number of sites needed for intensive monitoring, however due to the differences between methods, it is essential to determine the goal of the monitoring efforts prior to employing the characterization.

The complex hydrogeological makeup of this semi-arid region, coupled with its overall importance to the hydrology of the Grand Canyon, makes improving our understanding of groundwater vulnerability a high priority. This study, the first of its kind for the park, will evaluate the intrinsic vulnerability of the karstic groundwater basins of the Kaibab Plateau. Two multi-attribute geospatial groundwater vulnerability analyses were conducted using the COP and EPIK methods, both of which have been specifically designed for karstic aquifer systems. Due to the unique geologic makeup of the Kaibab Plateau, these models were compared to assess their ability to quantify the variability in vulnerability and to determine which is the most appropriate for the study within Grand Canyon National Park. The COP method is based on three factors: concentration of flow (C), overlying lithological layers (O), and precipitation regime (P). The EPIK method takes into account: epikarst (E), protective cover (P), infiltration conditions (I), and karst development (K). For each method, the parameters are subcategorized by weighted attributes and rasterized in GIS. The finalized raster layers are combined and spatially analyzed in GIS to create the final groundwater vulnerability map. In both models, the results suggest there is a low to moderate level of vulnerability in the catchment basin. Because groundwater vulnerability maps of aquifers are an effective tool for resource and land use planning, the results of this study will help facilitate decision making regarding aquifer protection and sustainable management practices.

This is not the only example of vertebrate fossil exploitation within the monument, but merely the most recent documented event. As a result, removal of the degraded specimen was required in order to properly stabilize and preserve the specimen for future scientific investigation, and thus is no longer viewable by visitors along the trail. In an attempt to mitigate future exploitation along the Morrison spur of the trail, a comprehensive map, and extensive photo documentation project occurred during the summer of 2015. The map established a grid system for the 200 ft Morrison spur and assigned reference numbers linking the map to high-quality photos of the bones. The map and photos will aid interpretive and paleontology staff in monitoring the condition and position of fossils, as well as educating visitors about the tragedy of vandalism. Neilson Gulch was protected by the establishment of the original 80 acre monument in 1915, and the Fossil Discovery Trail was established in the gulch as an interactive trail from Quarry Exhibit Hall to the DINO Visitor Center in 2006. The trail offers visitors a unique opportunity to observe the naturally exposed fossils of the Stump, Morrison, and Mowry Formation. Trails that lead visitors directly to exposed fossil vertebrates are rare due to fear of exploitation of fossils; however, with proper documentation of resources and informed visitors, the risk of exploitation can be diminished.

Here we summarize results from approximately 900 amino acid racemization (AAR) analyses of mollusks obtained from inner shelf core and grab sites, as well as dozens of beach collection sites, between New Jersey and Florida. North Carolina results dominate the dataset because of the availability of numerous samples along the Outer Banks and the nearby inner shelf. 14C results on selected samples provide calibration and distinguish Holocene from Pleistocene AAR results, while also identifying samples that were likely exposed to high beach surface temperatures. Mercenaria, Spisula, and Mulinia are the most commonly analyzed taxa. For Mercenaria, in many cases shell characteristics (particularly color and luster) are diagnostic of pre-Holocene ages for samples found on the Outer Banks beaches. Multiple Pleistocene aminozones are recognized in the NC beach aminostratigraphy, aminozones that correlate to units recognized in on-shore deposits with in-situ shells. Correlative inner-shelf aminozones represent the sources for beach shell material. Similarly, Pleistocene shells are recognized on both the Maryland shelf and at selected beaches of the Delmarva Peninsula. Simple histograms of AAR D/L amino acid values for individual approximately 50 km segments of the NC beaches reveal distinct clusters of apparent ages, with Holocene shells dominating the mix from 36.5 to 35.5 N. To the south, increasing relative abundances of Pleistocene beach shells are encountered, with the maximum found between Onslow Beach and Wrightsville Beach, NC. Shelf and beach samples from the Edisto Beach, Greys Reef, and Tybee Island region (SC-GA) also indicate an abundance of Pleistocene shell material. Although results are not uniformly distributed across the entire region of study, and artificial beach nourishment has undoubtedly affected results in selected areas, concentrations of Pleistocene shells (often with multiple ages) in surface deposits (inner shelf or beaches), indicate local sources of pre-Holocene sediment and/or absence of thick Holocene sediment cover.

Previous studies on the Cuyahoga River within Cuyahoga Valley National Park (CVNP) have found that predictive models can be used to provide accurate assessments of the recreational water quality. However, in order to run the previously developed nowcasts for CVNP, manual collection and processing of samples is required on a daily basis to acquire the required explanatory variable data (laboratory-measured turbidity). The U.S. Geological Survey and the National Park Service collaborated to develop a more automated approach to provide more timely results to park visitors regarding the recreational water quality of the river. In May 2012, an in-stream water-quality sensor was installed by the U.S. Geological Survey at Jaite, Ohio (a site centrally located in CVNP on the Cuyahoga River), to provide near-real-time measurements of turbidity and water temperature. To transition from methods used during previous studies at CVNP, a relation between laboratory- and in-stream measured turbidity was developed after the recreational season of 2012. During the recreational seasons of 2012 through 2014, discrete water samples were collected and processed to determine Escherichia coli (E. coli) concentrations at Jaite and one site upstream of Jaite (Lock 29) within CVNP. Predictive models, using in-stream turbidity measurements, were developed for the recreational seasons of 2013 and 2014 to estimate recreational water quality in regards to Ohio's single-sample water-quality standard for primary-contact recreation. A computer program was developed to manage the nowcasts by running the predictive models and posting the results to a publicly accessible Web site daily by 9 a.m. The nowcasts were able to correctly predict E. coli concentrations above or below the water-quality standard at Jaite for 79 percent of the samples compared with the measured concentrations. In comparison, the persistence model (using the previous day's sample concentration) correctly predicted concentrations above or below the water-quality standard in only 68 percent of the samples. To determine if the Jaite nowcast could be used for the stretch of the river between Lock 29 and Jaite, the model predictions for Jaite were compared with the measured concentrations at Lock 29.

Concerns have been raised about the influence of hatchery fish on wild populations. Carson National Fish Hatchery produces spring Chinook salmon Oncorhynchus tshawytscha in the Wind River, Washington, and some spawn in the river. Managers were concerned that Chinook salmon could negatively affect wild steelhead O. mykiss and that a self-sustaining population of Chinook salmon may develop. Our objectives were to assess: 1) the distribution and populations of juvenile spring Chinook salmon and juvenile steelhead in the upper Wind River; 2) the influence of stream flow and of each population on the other; and 3) if Chinook salmon populations were self-sustaining. We snorkeled to determine distribution and abundance. Flow in the fall influenced upstream distribution and abundance of juvenile Chinook salmon. Juvenile Chinook salmon densities were consistently low (range 0.0 to 5.7 fish 100 nr super(2)) and not influenced by number of spawners, winter flow magnitude, or steelhead abundance. Juvenile steelhead were distributed through the study section each year. Age-0 and age-1 steelhead densities (age-0 range: 0.04 to 37.0 fish 100 m super(2); age-1 range: 0.02 to 6.21 fish 100 m super(2)) were consistently higher than for juvenile Chinook salmon. Steelhead spawner abundance positively influenced juvenile steelhead abundance. During this study, Chinook salmon in the Wind River appear to have had little effect on steelhead. Low juvenile Chinook salmon abundance and a lack of a spawner-to-juvenile relationship suggest Chinook salmon are not self-sustaining and potential for such a population is low under current conditions.

During 2002-03, the U.S. Geological Survey, in cooperation with the National Park Service, collected aquatic invertebrates, amphibians, and fish, and analyzed them for Hg, cadmium, zinc, copper, and other metals and trace elements. The data from the biota, in conjunction with data from concurrent community bioassessments, habitat analyses, water quality, and concentrations of metals and trace elements in water and sediment, were used to identify contamination "hot spots." In 2002, we selected collection sites within the study area based on the presence of historical mines and results from sampling of bed sediment in 2001. In 2003, collection sites were selected based on sediment data as well as data on water and biota from this study in 2002. Eleven sites were sampled in both 2002 and 2003, 11 sites were sampled only in 2002, and 14 sites were sampled only in 2003. Comparisons of sites within the Upper Clear Creek watershed indicated that most of the more contaminated sites were outside of the park boundaries, especially at sites within the French Gulch, Cline Gulch, and Whiskey Creek watersheds. The site with the highest overall contamination within the park, based on both fish and invertebrate data, was WLCC, a site on Willow Creek impacted by acid mine drainage and listed as impaired under Section 303(d) of the Clean Water Act. Compared with other recently evaluated mine-impacted watersheds in northern California, invertebrates, amphibians, and fish from sites within the Upper Clear Creek watershed tended to have significantly lower concentrations of Hg than at most other sites. For other metals and trace elements, Upper Clear Creek sites were only compared with the Deer Creek watershed, Nevada County, California. Copper from both Willow Creek sites (WLCC and WLTH) in the Clear Creek watershed was the only metal with concentrations in biota that were significantly higher than biota from Deer Creek.

It exhibits a semi-anadromous life cycle spending adult life in low to moderate salinity (0-12) habitat with migrations into upstream freshwater rivers and floodplains for spawning during winter-spring. The species persists as two genetically distinguishable populations - one dominant and one subordinate - separated by discrete spawning habitats that we suggest resemble an island-mainland metapopulation structure. The populations overlap in distribution in the SFE, yet segregation is maintained with individuals tending to aggregate or school with others of similar population heritage and natal origin. The populations are spatially connected via dispersal of the dominant population into the subordinate population's spawning habitat when climate patterns produce freshwater outflow sufficient to form a bridge of suitable low salinity habitat across the upper SFE. Habitat affinities of the two populations, hydrodynamic modeling studies, and historical outflow records together suggest such conditions occur in approximately 1/3 of years overall with an irregular frequency. This dynamic pattern of spatial connectivity controlled by climate variability may be an important driver of gene flow between the two populations.Original Abstract: Pogonichthys macrolepidotus est un cyprinide demersal longevif (8 ans) relativement grand (400 mm) d'importance pour la conservation et endemique de l'estuaire de San Francisco (SFE; Californie, Etats-Unis). Il presente un cycle biologique semi-anadrome, passant sa vie adulte dans des habitats de salinite faible a moderee (0-12) avec des migrations dans des rivieres d'eau douce et des plaines alluviales situees plus en amont pour frayer a l'hiver et au printemps. L'espece persiste en deux populations genetiquement distinctes, une dominante et l'autre subordonnee, separees par des habitats de frai distincts qui ressemblent, selon nous, a une structure de metapopulation de type ile-continent. Si les aires de repartition des populations se chevauchent dans le SFE, une segregation est maintenue, les individus tendant a se regrouper ou former des bancs avec d'autres individus provenant de la meme population et de la meme origine natale. Les populations sont connectees dans l'espace par la dispersion de la population dominante dans l'habitat de frai de la population subordonnee quand les aleas du climat produisent des debits sortants d'eau douce assez importants pour former un pont d'habitats d'assez faible salinite de part en part du SFE superieur. La combinaison de l'affinite des habitats des deux populations, d'etudes de modelisation hydrodynamique et des registres historiques des debits sortants indiquerait que de telles conditions se produisent environ une annee sur trois, a une frequence irreguliere. Ce motif dynamique de connectivite spatiale controlee par la variabilite du climat pourrait etre une importante cause de flux genetique entre les deux populations.

Although there are reports of sightings of mountain lions or observations of mountain lion sign, most have not been verified by photographs or physical samples. A search of museums throughout the United States (Long and Sweitzer 2001) revealed that the only specimen from Marin County appears to be a mountain lion collected in 1931 (MVZ:Mamm:47199). Gross and Fitzhugh (1985) compiled a list of 148 reports of mountain lion observations in Marin County from 1961 to 1984 based on agency records or personal communications with local residents. The majority of those accounts were visual recollections that could not be verified, and no physical or photographic docmnentation accompanied any of the reports. Since 1972, four depredation pennits have been issued for mountain lions in Marin County, with no confinned kills under those pennits (CDFW 2014).

Correlations of Manix highstands with ice, marine, and speleothem records suggest that at least the youngest three highstands coincide with Dansgaard-Oeschger (D-O) stadials and Heinrich events 3 and 4. The lake-level record is consistent with results from speleothem studies in the Southwest that indicate cool wet conditions during D-O stadials. Notably, highstands between 43 and 25 ka apparently occurred at times of generally low levels of pluvial lakes farther north as interpreted from core-based proxies. Mojave lakes may have been supported by tropical moisture sources during oxygen-isotope stage 3, perhaps controlled by southerly deflection of Pacific storm tracks due to weakening of the sea-surface temperature gradient in response to North Atlantic climate perturbations.

A systematic process for evaluating the social and ecological risks, trade-offs, and co-benefits associated with future changes is critical to maximize resilience and conserve ecosystem services. This is particularly true in coastal areas where human populations and landscape conversion are increasing, and where intensifying storms and sea-level rise pose unprecedented threats to coastal ecosystems. We applied collaborative decision analysis with a diverse team of stakeholders who preserve, manage, or restore tidal marshes across the San Francisco Bay estuary, California, USA, as a case study. We found that strategies that avoided explicitly accounting for future climate change had the lowest expected performance based on input from the team. Our decision-analytic framework is sufficiently general to offer an adaptable template, which can be modified for use in other areas that include a diverse and engaged stakeholder group.

However, little is known about their distribution, how and under what conditions they form, and how their intriguing morphology translates to ecosystem functions and habitat. Here we report on a circum-Arctic survey of beaded streams and a watershed-scale analysis in northern Alaska using remote sensing and field studies. We mapped over 400 channel networks with beaded morphology throughout the continuous permafrost zone of northern Alaska, Canada, and Russia and found the highest abundance associated with medium to high ground-ice content permafrost in moderately sloping terrain. In one Arctic coastal plain watershed, beaded streams accounted for half of the drainage density, occurring primarily as low-order channels initiating from lakes and drained lake basins. Beaded streams predictably transition to alluvial channels with increasing drainage area and decreasing channel slope, although this transition is modified by local controls on water and sediment delivery. The comparisons of one beaded channel using repeat photography between 1948 and 2013 indicate a relatively stable landform, and (super 14) C dating of basal sediments suggest channel formation may be as early as the Pleistocene-Holocene transition. Contemporary processes, such as deep snow accumulation in riparian zones, effectively insulate channel ice and allows for perennial liquid water below most beaded stream pools. Because of this, mean annual temperatures in pool beds are greater than 2 degrees C, leading to the development of perennial thaw bulbs or taliks underlying these thermokarst features that range from 0.7 to 1.6 m. In the summer, some pools thermally stratify, which reduces permafrost thaw and maintains cold-water habitats. Snowmelt-generated peak flows decrease rapidly by two or more orders of magnitude to summer low flows with slow reach-scale velocity distributions ranging from 0.01 to 0.1 m s (super -1) , yet channel runs still move water rapidly between pools. The repeating spatial pattern associated with beaded stream morphology and hydrological dynamics may provide abundant and optimal foraging habitat for fish. Beaded streams may create important ecosystem functions and habitat in many permafrost landscapes and their distribution and dynamics are only beginning to be recognized in Arctic research.

Although sedimentary and geomorphic responses to sediment pulses are a fundamental part of landscape evolution, few opportunities exist to quantify those processes over field scales. We investigated the downstream effects of sediment released during the largest dam removal in history, on the Elwha River, Washington, USA, by measuring changes in riverbed elevation and topography, bed sediment grain size, and channel planform as two dams were removed in stages over two years. As 10.5 million t (7.1 million m (super 3) ) of sediment was released from two former reservoirs, downstream dispersion of a sediment wave caused widespread bed aggradation of approximately 1 m (greater where pools filled), changed the river from pool-riffle to braided morphology, and decreased the slope of the lowermost river. The newly deposited sediment, which was finer than most of the pre-dam-removal bed, formed new bars (largely pebble, granule, and sand material), prompting aggradational channel avulsion that increased the channel braiding index by almost 50%. As a result of mainstem bed aggradation, floodplain channels received flow and accumulated new sediment even during low to moderate flow conditions. The river system showed a two- to tenfold greater geomorphic response to dam removal (in terms of bed elevation change magnitude) than it had to a 40-year flood event four years before dam removal. Two years after dam removal began, as the river had started to incise through deposits of the initial sediment wave, approximately 1.2 million t of new sediment ( approximately 10% of the amount released from the two reservoirs) was stored along 18 river km of the mainstem channel and 25 km of floodplain channels. The Elwha River thus was able to transport most of the released sediment to the river mouth. The geomorphic alterations and changing bed sediment grain size along the Elwha River have important ecological implications, affecting aquatic habitat structure, benthic fauna, salmonid fish spawning and rearing potential, and riparian vegetation. The response of the river to dam removal represents a unique opportunity to observe and quantify fundamental geomorphic processes associated with a massive sediment influx, and also provides important lessons for future river-restoration endeavors.

The gauge network is a key driver in hydrologic modeling to characterize discharge. The accuracy of precipitation is dependent on the location of stations, the density of the network, and the interpolation scheme. Our study examines 16 weather stations in a 64 km super(2) catchment. We develop a weighted, distributed approach for gap-filling the observed meteorological dataset. We analyze five interpolation methods (Thiessen, IDW, nearest neighbor, spline, and ordinary Kriging) at five gauge densities. We utilize precipitation in a SWAT model to estimate discharge in lumped parameter simulations and in a distributed approach at the multiple densities (1, 16, 50, 142, and 300 stations). Gauge density has a substantial impact on distributed discharge and the optimal gauge density is between 50 and 142 stations. Our results also indicate that the IDW interpolation scheme was optimum, although the Kriging and Thiessen polygon methods produced similar results. To further examine variability in discharge, we characterized the land use and soil distribution throughout each of the subbasins. The optimal rain gauge position and distribution of the gauges drastically influence catchment-wide runoff. We found that it is best to locate the gauges near less permeable locations.

Since the initiation of injection at the PVU in 1991, earthquakes have been repeatedly induced. PVU closely monitors all seismicity in the Paradox Valley region with a dense surface seismic network. A key factor for understanding the seismic hazard from PVU injection is the maximum magnitude earthquake that can be induced. The estimate of maximum magnitude of induced earthquakes is difficult to constrain as, unlike naturally occurring earthquakes, the maximum magnitude of induced earthquakes changes over time and is affected by injection parameters. We investigate temporal variations in maximum magnitudes of induced earthquakes at the PVU using two methods. First, we consider the relationship between the total cumulative injected volume and the history of observed largest earthquakes at the PVU. Second, we explore the relationship between maximum magnitude and the geometry of individual seismicity clusters. Under the assumptions that: (i) elevated pore pressures must be distributed over an entire fault surface to initiate rupture and (ii) the location of induced events delineates volumes of sufficiently high pore-pressure to induce rupture, we calculate the largest allowable vertical penny-shaped faults, and investigate the potential earthquake magnitudes represented by their rupture. Results from both the injection volume and geometrical methods suggest that the PVU has the potential to induce events up to oughly MW 5 in the region directly surrounding the well; however, the largest observed earthquake to date has been about a magnitude unit smaller than this predicted maximum. In the seismicity cluster surrounding the injection well, the maximum potential earthquake size estimated by these methods and the observed maximum magnitudes have remained steady since the mid-2000s. These observations suggest that either these methods overpredict maximum magnitude for this area or that long time delays are required for sufficient pore-pressure diffusion to occur to cause rupture along an entire fault segment. We note that earthquake clusters can initiate and grow rapidly over the course of 1 or 2 yr, thus making it difficult to predict maximum earthquake magnitudes far into the future. The abrupt onset of seismicity with injection indicates that pore-pressure increases near the well have been sufficient to trigger earthquakes under pre-existing tectonic stresses. However, we do not observe remote triggering from large teleseismic earthquakes, which suggests that the stress perturbations generated from those events are too small to trigger rupture, even with the increased pore pressures.

Although many recent river-restoration efforts have included dam removal, large dam removals have been rare enough that their physical and ecological effects remain poorly understood. New sedimentary deposits that formed during this multi-stage dam removal result from a unique, artificially created imbalance between fluvial sediment supply and transport capacity. River flows during dam removal were essentially natural and included no large floods in the first two years, while draining of the two reservoirs greatly increased the sediment supply available for fluvial transport. The resulting sedimentary deposits exhibited substantial spatial heterogeneity in thickness, stratal-formation patterns, grain size and organic content. Initial mud deposition in the first year of dam removal filled pore spaces in the pre-dam-removal cobble bed, potentially causing ecological disturbance but not aggrading the bed substantially at first. During the second winter of dam removal, thicker and in some cases coarser deposits replaced the early mud deposits. By 18 months into dam removal, channel-margin and floodplain deposits were commonly >0.5 m thick and, contrary to pre-dam-removal predictions that silt and clay would bypass the river system, included average mud content around 20%. Large wood and lenses of smaller organic particles were common in the new deposits, presumably contributing additional carbon and nutrients to the ecosystem downstream of the dam sites. Understanding initial sedimentary response to the Elwha River dam removals will inform subsequent analyses of longer-term sedimentary, geomorphic and ecosystem changes in this fluvial and coastal system, and will provide important lessons for other river-restoration efforts where large dam removal is planned or proposed.

We used an image reconstruction approach to compare postfire albedo with the albedo assuming that no fires had occurred. Combining the fire-caused albedo change from the 2001-2010 fires in interior Alaska and the monthly surface incoming solar radiation, we examined the spatiotemporal variation of SSF in the early successional stage of approximately 10 years. Our results showed that although postfire albedo generally increased in fall, winter, and spring, some burned areas could show an albedo decrease during these seasons. In summer, the albedo increased for several years and then declined again. The spring SSF distribution did not show a latitudinal decrease from south to north as previously reported. The results also indicated that although the SSF is usually largely negative in the early successional years, it may not be significant during the first postfire year. The annual 2005-2010 SSF for the 2004 fire scars was -1.30, -4.40, -3.31, -4.00, -3.42, and -2.47 W.m super(-2), respectively. The integrated annual SSF map showed significant spatial variation, with a mean of -3.15 W.m super(-2), a standard deviation of 3.26 watts per square metre (W.m super(-2)), and 16% of burned areas having positive SSF. Our results suggest that boreal deciduous fires would be less positive for climate change than boreal evergreen fires. Future research is needed to comprehensively investigate the spatiotemporal radiative and nonradiative forcings to determine the effect of boreal fires on the climate.Original Abstract: La modification de l'albedo causee par les feux et la succession vegetale subsequente est spatialement heterogene. Il est donc necessaire d'avoir acces a la variation spatio-temporelle du forcage aux courtes longueurs d'onde de la surface en tant que composante pour quantifier les impacts des feux aux latitudes elevees sur le climat. Nous avons utilise la reconstruction d'image pour comparer l'albedo apres feu a celui qu'on aurait pu mesurer s'il n'y avait pas eu de feu. En combinant la modification de l'albedo causee par les feux de 2001 a 2010 a l'interieur de l'Alaska et le rayonnement solaire mensuel incident a la surface, nous avons etudie la variation spatio-temporelle du forcage au stade precoce de succession sur une periode d'environ 10 ans. Nos resultats ont montre que, bien que l'albedo apres feu ait generalement augmente a l'automne, en hiver et au printemps, il pouvait diminuer durant ces saisons dans certaines zones brulees. En ete, l'albedo a augmente pendant plusieurs annees et diminue a nouveau par la suite. Il n'y a pas eu de diminution latitudinale de la distribution printaniere du forcage, du sud vers le nord, comme cela a deja ete rapporte. Les resultats indiquent aussi que meme si le forcage est habituellement largement negatif durant les premieres annees de la succession, il peut ne pas etre significatif durant les premieres annees apres feu. Le forcage annuel de 2005 a 2010 pour les cicatrices de feu de 2004 mesurait : -1,30, -4,40, -3,31, -4,00, -3,42 et -2,47 W.m super(-2). La carte du forcage annuel integre montre qu'il y a une variation spatiale significative avec une moyenne de -3,15 W.m super(-2) et un ecart type de 3,26 W.m super(-2), 16 % des zones brulees ayant un forcage positif. Nos resultats indiquent que les feux en zone boreale decidue seraient moins benefiques pour les changements climatiques que les feux en zone boreale resineuse. D'autres travaux seront necessaires pour etudier a fond les forcages radiatifs et non radiatifs afin de determiner l'effet des feux en zone boreale sur le climat.

We studied microbial community responses to restoration of a subtropical seagrass meadow disturbed by vessel groundings in south Florida, USA, and relationships between microbial communities and sediment properties at the study sites using terminal restriction fragment length polymorphism. Two restoration methods were evaluated: the installation of bird roosting stakes as a means to provide a nutrient source, and placement of sand fill into excavations to prevent erosion. Both disturbed and restoration sites had less complex microbial community structure than undisturbed reference seagrass sediments. Microbial community structure varied little between disturbed and fertilized sites, but was distinct in filled sites. Sediment bulk density, sediment organic matter and total phosphorus content, porewater ammonium, soluble reactive phosphorus, and dissolved sulfide concentrations were important environmental predictors of microbial community structure across the restoration treatments. We show that community structure and diversity varied with sediment depth, among restoration treatments, and through time. Our results indicate that microbial communities in seagrass meadows are changed by physical disturbance of the rhizosphere, and that common restoration techniques lead to the formation of distinct microbial communities during the first year of recovery.

The mission of the SOS is to collect wildland native seed for long-term germplasm conservation and for use in seed research, development of native plant materials, and ecosystem restoration. Each year about 50 SOS teams are stationed across the United States to make seed collections following a single technical protocol. SOS collections are divided into a long-term conservation storage collection, which is stored at multiple USDA Agricultural Research Service seed storage facilities, and a working collection, which is stored at partner institutions and made available for research. In addition to collecting and banking native species for future uses, SOS provides seed that can be increased to provide genetically appropriate plant materials for ecological restoration of disturbed lands. Seed collection is an efficient and cost-effective method for conserving the diversity of plant species into the future. Partners located throughout the United States are critical to the success of this program.

The more heavily impacted regions often require active intervention. Historically, this intervention has been conducted primarily by seeding introduced grasses selected for their forage characteristics. Recent management initiatives that reflect broader goals have highlighted the need to develop native plant materials that can be used to return diverse, resilient communities to degraded areas. The Colorado Plateau Native Plant Program was established to identify the best native plant species, and seed sources within species, that can be used to meet this need. We present an overview of the Program's past and current activities and highlight research and development strategies used to increase the availability of native plant materials adapted to target sites.

We investigated the interplay among uplift, river incision, and hillslope response in the nonglacial Waipaoa River catchment located in the exhumed inner forearc of an active subduction margin on the East Coast of the North Island of New Zealand. New high-resolution topographic data sets (light detection and ranging [lidar] and photogrammetry) combined with field mapping and tephrochronology indicate that hillslopes adjusted to rapid latest Pleistocene and Holocene river incision through the initiation and reactivation of deep-seated landslides. In the erodible marine sedimentary rocks of the Waipaoa sedimentary system, postincision deep-seated landslides can occupy over 30% of the surface area. The ages of tephra cover beds identified by electron microprobe analysis on 80 tephra samples from 173 soil test pits and 64 soil auger sites show that 4000-5000 yr after the initiation of river incision, widespread hillslope adjustment started between the deposition of the ca. 14,000 cal. yr B.P. Waiohau Tephra and the ca. 9420 cal. yr B.P. Rotoma Tephra. Tephrochronology and geomorphic mapping analysis indicate that river incision and deep-seated landslide slope adjustment were synchronous between main-stem rivers and headwater tributaries. Hillslope response in the catchment can include the entire slope, measured from river to ridgeline, and, in some cases, the interfluves between incising subcatchments have been dramatically modified through ridgeline retreat and/or lowering. Using the results of our landform tephrochronology and geomorphic mapping, we derive a conceptual time series of hillslope response to uplift and climate change-induced river incision over the last glacial-interglacial cycle.

Controlled studies were performed in a large-scale, open-channel flume, and all individuals approached the turbine under volitional control. No injuries were observed, and there was no measurable increase in mortality associated with turbine passage. Exposure to the turbine elicited behavioral responses from both species, however, with salmon passing primarily over the downrunning blades. Shad movement was impeded by the device, as indicated by fewer attempts of shorter duration and reduced distance of ascent up the flume. More work should be performed in both laboratory and field conditions to determine to what extent these effects are likely to influence free-swimming fish.

Vulnerability assessments primarily have been based on single hazard zones, even though a coastal community may be threatened by multiple tsunami sources that vary locally in terms of inundation extents and wave arrival times. We use the Alaskan coastal communities of Cordova, Kodiak, Seward, Valdez, and Whittier (USA), as a case study to explore population vulnerability to multiple tsunami threats. We use anisotropic pedestrian evacuation models to assess variations in population exposure as a function of travel time out of hazard zones associated with tectonic and landslide-related tsunamis (based on scenarios similar to the 1964 M sub(w) 9.2 Good Friday earthquake and tsunami disaster). Results demonstrate that there are thousands of residents, employees, and business customers in tsunami hazard zones associated with tectonically generated waves, but that at-risk individuals will likely have sufficient time to evacuate to high ground before waves are estimated to arrive 30-60 min after generation. Tsunami hazard zones associated with submarine landslides initiated by a subduction zone earthquake are smaller and contain fewer people, but many at-risk individuals may not have enough time to evacuate as waves are estimated to arrive in 1-2 min and evacuations may need to occur during earthquake ground shaking. For all hazard zones, employees and customers at businesses far outnumber residents at their homes and evacuation travel times are highest on docks and along waterfronts. Results suggest that population vulnerability studies related to tsunami hazards should recognize non-residential populations and differences in wave arrival times if emergency managers are to develop realistic preparedness and outreach efforts.

We used DNA sequence data from multiple genetic markers and coalescent-based phylogenetic methods to place the Guam population within the broader phylogeographic context of B. irregularis across its native range and tested whether patterns of genetic variation on the island are consistent with one or multiple introductions from different source populations. We also modeled a series of demographic scenarios that differed in the effective size and duration of a population bottleneck immediately following the invasion on Guam, and measured the fit of these simulations to the observed data using approximate Bayesian computation. Our results exclude the possibility of serial introductions from different source populations, and instead verify a single origin from the Admiralty Archipelago off the north coast of Papua New Guinea. This finding is consistent with the hypothesis that B. irregularis was accidentally transported to Guam during military relocation efforts at the end of World War II. Demographic model comparisons suggest that multiple snakes were transported to Guam from the source locality, but that fewer than 10 individuals could be responsible for establishing the population. Our results also provide evidence that low genetic diversity stemming from the founder event has not been a hindrance to the ecological success of B. irregularis on Guam, and at the same time offers a unique 'genetic opening' to manage snake density using classical biological approaches.

We assigned six life history traits - fecundity, longevity, maturation age, maximum total length, parental care, and spawning season duration - to each fish species. Decreaser species were significantly smaller in size and shorter-lived with reduced fecundity and shorter spawning seasons compared to increaser species. Cluster analysis of traits revealed correspondence with a life history model defining equilibrium (low fecundity, high parental care), opportunistic (early maturation, low parental care), and periodic (late maturation, high fecundity, low parental care) end-point strategies. Nearly 50 % of decreaser species were associated with an intermediate opportunistic-periodic strategy, suggesting that abiotic factors such as habitat specialization and streamflow alteration may serve as important influences on life history traits and strategies of decreaser species. In contrast, the percent of increaser species among life history strategy groups ranged from 21 to 32 %, suggesting that life history strategies of increaser species were more diverse than those of decreaser species. This study highlights the utility of linking life history theory to biodiversity to better understand mechanisms that contribute to fish species distributions in the eastern U.S. JF - Environmental Biology of Fishes AU - Meador, Michael R AU - Brown, Larry M AD - U.S. Geological Survey, 12201 Sunrise Valley Drive, MS 413, Reston, VA, 20192, USA, mrmeador@usgs.gov Y1 - 2015/01// PY - 2015 DA - January 2015 SP - 663 EP - 677 PB - Springer Science+Business Media, Van Godewijckstraat 30 Dordrecht 3311 GX Netherlands VL - 98 IS - 2 SN - 0378-1909, 0378-1909 KW - Aqualine Abstracts; Water Resources Abstracts; Animal Behavior Abstracts; Ecology Abstracts; ASFA 1: Biological Sciences & Living Resources; Sustainability Science Abstracts KW - Biological diversity KW - Utilities KW - Abiotic factors KW - Spawning seasons KW - Habitat KW - Model Studies KW - Fecundity KW - Aquatic Habitats KW - Sexual maturity KW - Reproductive cycle KW - Fish KW - Age KW - Ecological distribution KW - Specialization KW - Parental behaviour KW - Biodiversity KW - Streams KW - Flow rates KW - Models KW - History KW - Prediction models KW - Streamflow KW - Spawning KW - Longevity KW - USA KW - Life history KW - AQ 00001:Water Resources and Supplies KW - Y 25020:Territory, Reproduction and Sociality KW - SW 0810:General KW - M3 1010:Issues in Sustainable Development KW - D 04040:Ecosystem and Ecology Studies KW - Q1 08442:Population dynamics UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1647025262?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Aaqualine&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Environmental+Biology+of+Fishes&rft.atitle=Life+history+strategies+of+fish+species+and+biodiversity+in+eastern+USA+streams&rft.au=Meador%2C+Michael+R%3BBrown%2C+Larry+M&rft.aulast=Meador&rft.aufirst=Michael&rft.date=2015-01-01&rft.volume=98&rft.issue=2&rft.spage=663&rft.isbn=&rft.btitle=&rft.title=Environmental+Biology+of+Fishes&rft.issn=03781909&rft_id=info:doi/10.1007%2Fs10641-014-0304-1 LA - English DB - ProQuest Environmental Science Collection N1 - Date revised - 2015-01-01 N1 - Number of references - 36 N1 - Last updated - 2016-02-04 N1 - SubjectsTermNotLitGenreText - Spawning seasons; Fecundity; Reproductive cycle; Ecological distribution; Sexual maturity; Biodiversity; Parental behaviour; Streams; Abiotic factors; Age; Life history; Specialization; Spawning; Habitat; Longevity; Models; Prediction models; Biological diversity; Fish; Flow rates; Aquatic Habitats; History; Streamflow; Utilities; Model Studies; USA DO - http://dx.doi.org/10.1007/s10641-014-0304-1 ER - TY - JOUR T1 - Long-Term Groundwater Depletion in the United States AN - 1647024914; 21310956 AB - The volume of groundwater stored in the subsurface in the United States decreased by almost 1000 km3 during 1900-2008. The aquifer systems with the three largest volumes of storage depletion include the High Plains aquifer, the Mississippi Embayment section of the Gulf Coastal Plain aquifer system, and the Central Valley of California. Depletion rates accelerated during 1945-1960, averaging 13.6 km3/year during the last half of the century, and after 2000 increased again to about 24 km3/year. Depletion intensity is a new parameter, introduced here, to provide a more consistent basis for comparing storage depletion problems among various aquifers by factoring in time and areal extent of the aquifer. During 2001-2008, the Central Valley of California had the largest depletion intensity. Groundwater depletion in the United States can explain 1.4% of observed sea-level rise during the 108-year study period and 2.1% during 2001-2008. Groundwater depletion must be confronted on local and regional scales to help reduce demand (primarily in irrigated agriculture) and/or increase supply.

Temperature anomalies for two periods, 1961-1985 and 1985-2010, relative to the climate normal period of 1971-2000, indicate that the latter period was statistically significantly warmer than the former for both mean AT and WT. Statistically significant temporal trends across the region of 0.023 degree C per year for AT and 0.028 degree C per year for WT are detected using simple linear regression. Sensitivity analyses show that the irregularly sampled WT data are appropriate for trend analyses, resulting in conservative estimates of trend magnitude. Relations between 190 landscape factors and significant trends in AT-WT relations are examined using principal components analysis. Measures of major dams and deciduous forest are correlated with WT increasing slower than AT, whereas agriculture in the absence of major dams is correlated with WT increasing faster than AT. Increasing WT trends are detected despite increasing trends in streamflow in the northern part of the study area. Continued warming of contributing streams to Chesapeake Bay likely will result in shifts in distributions of aquatic biota and contribute to worsened eutrophic conditions in the bay and its estuaries.

Little is known, however, about the more subtle toxicological effects of wildfires, particularly in downstream marine or downwind locations from the wildfire perimeter. These down-current effects may be just as substantial as those effects within the perimeter. We used gene transcription technology, a sensitive indicator of immunological perturbation, to study the effects of the 2008 Basin Complex Fire on the California coast on a sentinel marine species, the sea otter (Enhydra lutris). We captured sea otters in 2008 (3 mo after the Basin Complex Fire was controlled) and 2009 (15 mo after the Basin Complex Fire was controlled) in the adjacent nearshore environment near Big Sur, California. Gene responses were distinctly different between Big Sur temporal groups, signifying detoxification of PAHs, possible associated response to potential malignant transformation, and suppression of immune function as the primary responses of sea otters to fire in 2008 compared to those captured in 2009. In general, gene transcription patterns in the 2008 sea otters were indicative of molecular reactions to organic exposure, malignant transformation, and decreased ability to respond to pathogens that seemed to consistent with short-term hydrocarbon exposure.

This study characterizes the genetic diversity and relatedness of the Basin's Black Carp and clarifies the introduction history. Analyses focused on three mitochondrial markers (control region, cytochrome-b, and 16S) and seven nuclear microsatellite markers (nDNA), using aquaculture and wild-caught samples collected in the upper and lower Mississippi Basin. Of the three mitochondrial haplotypes, two were shared between the aquaculture and wild populations, while a third was only present in upper Mississippi wild-caught specimens. Due to the presence of diploid and triploid fish, microsatellite markers were scored as pseudodominant and revealed low polymorphism (N sub(A) = 4.6, N sub(A Ave) = 1.5). Nuclear Bayesian clustering analyses identified two genetically distinct groups and four subclusters, each primarily composed of a unique haplotype. Samples from three aquaculture farms were assigned to group 1, while a fourth farm included samples from both groups 1 and 2. Wild-caught fish from the upper Basin were predominantly group 1, whereas wild samples from the lower Mississippi were assigned to both genetic groups. The presence of divergent haplotypes and distinct nDNA groups, along with geographic distribution patterns, indicate that wild populations in the basin likely resulted from multiple introductions. Genetic similarities between wild and captive populations support claims that aquaculture is the introduction source, but a shortage of samples and a history of repeated transfers among facilities obscure the precise pathway.

Assessment of critical loads, which are the maximum exposure to pollution an area can receive without adverse effects on sensitive ecosystems, requires accurate deposition estimates. However, deposition is difficult and expensive to measure in high-elevation wilderness, and spatial patterns in N and S deposition in these areas remain poorly quantified. In this study, ion-exchange resin (IER) collectors were used to measure dissolved inorganic N (DIN) and S deposition during June 2006-September 2007 at approximately 20 alpine/subalpine sites spanning the Continental Divide in Rocky Mountain National Park. Results indicated good agreement between deposition estimated from IER collectors and commonly used wet + dry methods during summer, but poor agreement during winter. Snowpack sampling was found to be a more accurate way of quantifying DIN and S deposition during winter. Summer DIN deposition was significantly greater on the east side of the park than on the west side (25-50%; p less than or equal to 0.03), consistent with transport of pollutants to the park from urban and agricultural areas to the east. Sources of atmospheric nitrate (NO3 -) were examined using N isotopes. The average delta 15N of NO3 - from IER collectors was 3.5ppt higher during winter than during summer (p < 0.001), indicating a seasonal shift in the relative importance of regional NOx sources, such as coal combustion and vehicular sources of atmospheric NO3 -. There were no significant differences in delta 15N of NO3 - between east and west sides of the park during summer or winter (p = 0.83), indicating that the two areas may have similar sources of atmospheric NO3 -. Results from this study indicate that a combination of IER collectors and snowpack sampling can be used to characterize spatial variability in DIN and S deposition in high-elevation wilderness areas. These data can improve our ability to model critical loads by filling gaps in geographic coverage of deposition monitoring/modeling programs and thus may enable policy makers to better protect sensitive natural resources in Class 1 Wilderness areas.

Aspen forests and woodlands provide numerous ecosystem services, such as high primary productivity and biodiversity, retention and storage of environmental variables (precipitation, temperature, snow-water equivalent) that affect the spring and fall phenology of the aspen woodland communities of southwestern Colorado. We assessed the land surface phenology of aspen woodlands using two phenology indices, start of season time (SOST) and end of season time (EOST), from the U.S. Geological Survey (USGS) database of conterminous U.S. phenological indicators over an 11-year time period (2001-2011). These indicators were developed with 250m resolution remotely sensed data from the Moderate Resolution Imaging Spectroradiometer processed to highlight vegetation response. We compiled data on SOST, EOST, elevation, precipitation, air temperature, and snow water equivalent (SWE) for selected sites having more than 80% cover by aspen woodland communities. In the 11-year time frame of our study, EOST had significant positive correlation with minimum fall temperature and significant negative correlation with fall precipitation. SOST had a significant positive correlation with spring SWE and spring maximum temperature.

The recent availability of switchgrass land cover maps derived from the National Agricultural Statistics Service cropland data layer for the conterminous United States provides an opportunity to assess the environmental conditions of switchgrass over large areas and across different geographic locations. The main goal of this study is to develop a data-driven multiple regression switchgrass productivity model and identify the optimal climate and environment conditions for the highly productive switchgrass in the Great Plains (GP). Environmental and climate variables used in the study include elevation, soil organic carbon, available water capacity, climate, and seasonal weather. Satellite-derived growing season averaged Normalized Difference Vegetation Index (GSN) was used as a proxy for switchgrass productivity. Multiple regression analyses indicate that there are strong correlations between site environmental variables and switchgrass productivity (r =0.95). Sufficient precipitation and suitable temperature during the growing season (i.e., not too hot or too cold) are favorable for switchgrass growth. Elevation and soil characteristics (e.g., soil available water capacity) are also an important factor impacting switchgrass productivity. An anticipated switchgrass biomass productivity map for the entire GP based on site environmental and climate conditions and switchgrass productivity model was generated. Highly productive switchgrass areas are mainly located in the eastern part of the GP. Results from this study can help land managers and biofuel plant investors better understand the general environmental and climate conditions influencing switchgrass growth and make optimal land use decisions regarding switchgrass development in the GP.

Models were developed with and without exclusion of rare taxa at a site. BRT models are robust, requiring few assumptions compared with traditional modeling techniques such as multiple linear regression. The BRT models were constructed to provide baseline support to stressor delineation by identifying natural physiographic and human land use gradients affecting stream biological condition statewide and for eight ecological regions within the state, as part of the development of numerical biological objectives for California's wadeable streams. Regions were defined on the basis of ecological, hydrologic, and jurisdictional factors and roughly corresponded with ecoregions. Physiographic and land use variables were derived from geographic information system coverages. The model for the entire state (n=1,386) identified a composite measure of anthropogenic disturbance (the sum of urban, agricultural, and unmanaged roadside vegetation land cover) within the local watershed as the most important variable, explaining 56 % of the variance in O/E values. Models for individual regions explained between 51 and 84 % of the variance in O/E values. Measures of human disturbance were important in the three coastal regions. In the South Coast and Coastal Chaparral, local watershed measures of urbanization were the most important variables related to biological condition, while in the North Coast the composite measure of human disturbance at the watershed scale was most important. In the two mountain regions, natural gradients were most important, including slope, precipitation, and temperature. The remaining three regions had relatively small sample sizes (n less than or equal to 75 sites) and had models that gave mixed results. Understanding the spatial scale at which land use and land cover affect taxonomic completeness is imperative for sound management. Our results suggest that invertebrate taxonomic completeness is affected by human disturbance at the statewide and regional levels, with some differences among regions in the importance of natural gradients and types of human disturbance. The construction and application of models similar to the ones presented here could be useful in the planning and prioritization of actions for protection and conservation of biodiversity in California streams.

Our paleoseismic studies at Haehl Creek suggest that the Maacama fault has produced infrequent large earthquakes in addition to creep. Fault terminations observed in several excavations provide evidence that a prehistoric surface-rupturing earthquake occurred between 1060 and 1180 calibrated years (cal) B.P. at the Haehl Creek site. A folding event, which we attribute to a more recent large earthquake, occurred between 790 and 1060 cal B.P. In the last 560-690 years, a buried channel deposit has been offset 4.6 plus or minus 0.2 m, giving an average slip rate of 6.4-8.6 mm/yr, which is higher than the creep rate over the last 20 years. The difference between this slip rate and the creep rate suggests that coseismic slip up to 1.7 m could have occurred after the formation of the channel deposit and could be due to a paleoearthquake known from paleoseismic studies in the Ukiah Valley, about 25 km to the southeast. Therefore, we infer that at least two, and possibly three, large earthquakes have occurred at the Haehl Creek site since 1180 cal B.P. (770 C.E.), consistent with earlier studies suggesting infrequent, large earthquakes on the Maacama fault. The short-term geodetic slip rate across the Maacama fault zone is approximately twice the slip rate that we have documented at the Haehl Creek site, which is averaged over the last approximately 600 years. If the geodetic rate represents the long-term slip accumulation across the fault zone, then we infer that, in the last similar to 1200 years, additional earthquakes may have occurred either on the Haehl Creek segment of the Maacama fault or on other active faults within the Maacama fault zone at this latitude.Online Material: Trench logs, discussion of channel B, photographs of compressional features, and table of radiocarbon analyses.

201517510 AB - Federal land management agencies are increasingly relying on collaborative partnerships for managing national trails, heritage areas, scenic rivers, and recreation areas. For agencies such as the National Park Service, these joint approaches are significantly different from traditional management approaches. This article uses a case study of the Juan Bautista De Anza National Historic Trail to identify partnership lessons for this case and other protected areas that rely on public-private partnerships. The research highlights partnership issues with nonprofit capacity and mission alignment, project momentum, and leadership dilemmas. We suggest that agencies such as the National Park Service need to assess the mission and capacity of community and nonprofit groups to determine their partnership approach. This is a significant shift, from agencies simply needing to find organizations willing to partner on collaborative management efforts, to a role in assessing, forming, and developing nonprofit partners.

These studies are required to comprehend and model how such dust-on-snow (DOS) layers affect rates of snow melt through changes in the albedo of snow surfaces. We evaluated several constituents as potential contributors to the absorption of solar radiation indicated by values of absolute reflectance determined from bi-conical reflectance spectroscopy. Ferric oxide minerals and carbonaceous matter appear to be the primary influences on lowering snow-cover albedo. Techniques of reflectance and Moessbauer spectroscopy as well as rock magnetism provide information about the types, amounts, and grain sizes of ferric oxide minerals. Relatively high amounts of ferric oxide, indicated by hard isothermal remanent magnetization (HIRM), are associated with relatively low average reflectance (<0.25) across the visible wavelengths of the electromagnetic spectrum. Moessbauer spectroscopy indicates roughly equal amounts of hematite and goethite, representing about 35% of the total Fe-bearing phases. Nevertheless, goethite (alpha -FeOOH) is the dominant ferric oxide found by reflectance spectroscopy and thus appears to be the main iron oxide control on absorption of solar radiation. At least some goethite occurs as nano-phase grain coatings less than about 50 nm thick. Relatively high amounts of organic carbon, indicating as much as about 10% organic matter, are also associated with lower reflectance values. The organic matter, although not fully characterized by type, correlates strongly with metals (e.g., Cu, Pb, As, Cd, Mo, Zn) derived from distal urban and industrial settings, probably including mining and smelting sites. This relation suggests anthropogenic sources for at least some of the carbonaceous matter, such as emissions from transportation and industrial activities. The composition of the DOS samples can be compared with sediments in a likely dust-source setting at the Milford Flat Fire (MFF) area about 225 km southwest of Salt Lake City. The MFF area represents geologically and physiographically similar and widespread dust sources west-southwest of the Wasatch Range and heavily populated Wasatch Front. The DOS layers and MFF sediments are similar in some textural, chemical, and magnetic properties, as well as in the common presence of goethite, hematite, magnetite-bearing basalt fragments, quartz, plagioclase, illite, and kaolinite. Textural and some chemical differences among these deposits can be explained by atmospheric sorting as well as by inputs from other settings, such as salt-crusted playas and contaminant sources.

It is believed that areas underneath plant canopy have been conditioned to act as sediment, nutrients and water sinks whereas interspaces evolve into flow concentration pathways acting as source areas. This vegetation - hydrology feedback mechanism is part of a broader Vegetation Driven Spatial Heterogeneity (VDSH) concept that has been traditionally studied from a theoretical stand point but with little support from experimental data. In shrub-dominated rangeland communities, this VDSH concept implies that spatial distribution of vegetation can be used to model: (1) the level of hillslope dissection into concentrated flow and sheet flow areas and (2) the magnitude of sediment entrapment (deposition) expected from a given vegetation spatial arrangement. In this study, we developed a methodology to test these two hypotheses and derive practical equations for modeling purposes. From a series of rainfall/runoff experiments on naturally vegetated shrubland erosion plots, flow concentration and erosion/deposition processes were quantified using a combination of sediment yield data and high resolution microtopographic changes detected with advance 3D reconstruction technologies (lidar and photogrammetry). This study is expected to produce for the first time (1) predictive equations for spatial frequency of flow concentration pathways in shrub-dominated rangeland communities and (2) equations for sediment delivery ratio, a measure of the portion of eroded sediment that reaches the hillslope outlet as a function of vegetation spatial arrangement.

Since the USGS was established in 1879, hundreds of thousands of samples have been gathered in collections that range from localized, geographically-based assemblages to ones that are national or international in scope. These materials include, but are not limited to, rock and mineral specimens; fossils; drill cores and cuttings; geochemical standards; and soil, sediment, and geochemical samples. The USGS National Geological and Geophysical Data Preservation Program (NGGDPP) was established with the passage of the Energy Policy Act of 2005. Since its implementation, the USGS NGGDPP has taken an active role in providing opportunities to inventory, archive and preserve geologic and geophysical samples, and to make these samples and ancillary data discoverable on the Internet. Preserving endangered geoscience collections is more cost effective than recollecting this information. Preserving these collections, however, is only one part of the process--there also needs to be a means to facilitate open discovery and access to the physical objects and the ancillary digital records. The NGGDPP has celebrated successes such as the development of the USGS Geologic Collections Management System (GCMS), a master catalog and collections management plan, and the implementation and advancement of the National Digital Catalog, a digital inventory and catalog of geological and geophysical data and collections held by the USGS and State geological surveys. Over this period of time there has been many lessons learned. With the successes and lessons learned, NGGDPP is poised to take on challenges the future may bring.

Among other factors, sediment accumulation rates and patterns play an important role in governing the stability of delta front sediment. High sedimentation rates result in underconsolidation, slope steepening, and increased biogenic gas production, which are all known to decrease stability. Sedimentation rates are highly variable across the MRDF, but are highest near the mouth of Southwest Pass, which carries the largest percentage of Mississippi River sediment into the Gulf of Mexico. Since the 1950s, the sediment load of the Mississippi River has decreased by approximately 50% due to dam construction upstream. The impact of this decreased sediment load on MRDF mudflow dynamics has yet to be examined. We compiled MRDF bathymetric datasets, including historical charts, industry and academic surveys, and NOAA data, collected between 1764 and 2009, in order to identify historic trends in sedimentation patterns. The progradation of Southwest Pass (measured at 10 m depth contour) has slowed from approximately 66 m/yr between 1764 and 1940 to approximately 25 m/yr between 1940 and 1979, with evidence of further deceleration from 1979-2009. Decreased rates of progradation are also observed at South Pass and Pass A Loutre. Advancement of the delta also decelerated in deeper water (15-90 m) offshore from Southwest Pass. In this area, from 1940-1979, depth contours advanced seaward approximately 25 m/yr, but did not advance from 1979-2005. Furthermore, over the same area and time ranges, the sediment accumulation rate decreased by approximately 82%. We expect these sedimentation trends are occurring across the delta front, with potential impacts on spatial and temporal patterns of subaqueous mudflows. The MRDF appears to be entering a phase of decline, which will likely be accelerated by future upstream sediment diversion projects. New geophysical data will be required to assess potential mudflow hazards associated with new MRDF sedimentation rates and patterns (See Part 2, Obelcz et al.).

In 1969 cyclic seafloor wave loading associated with the passage of Hurricane Camille triggered subaqueous mudflows across the MRDF, destroying several offshore oil platforms. This incident spurred geophysical and geotechnical studies of the MRDF, which found that the delta front is prone to mass failures on gentle gradients (<0.5 degrees ) due to (1) high rates of fine-grained sedimentation and associated underconsolidation, (2) excess sediment pore pressure attributed to in-situ biogenic gas production, and (3) the frequent passage of tropical cyclones. In June 2014, a geophysical pilot study was conducted 8 km southwest of Southwest Pass, the distributary that currently receives the largest fraction of Mississippi River sediment supply. The resultant dataset encompasses 216 km of subbottom Chirp seismic profiles and a 60 km2 grid of bathymetry and sidescan data. Preliminary interpretation of these data shows the survey area can be classified into four primary sedimentary facies: mudflow gullies, mudflow lobes, undisturbed prodelta, and undisturbed delta front. Subbottom profiles reveal extensive biogenic gas from 20 to about 80 m water depths on the delta front; sidescan data show a variety of bottleneck slides, mudflow gullies and mudflow noses. Previous studies have attempted to constrain the periodicity and magnitude of subaqueous mudslides on the MRDF. However, large age gaps and varied resolution between datasets result in ambiguity regarding the cause and magnitude of observed bathymetric changes. We present high-temporal resolution MRDF bathymetric variations from 2005 (post Hurricane Katrina), 2009 (relatively quiescent storm period), and 2014 (post 2011 Mississippi River flood). These data yield better magnitude and timing estimates of mass movements. This exercise represents a first step towards (1) assembling a comprehensive geologic dataset upon which future MRDF geohazard assessments can be founded, and (2) understanding the dynamics of a massive passive margin deltaic lobe entering a phase of decline.

Conversely, surface-water management operations effect groundwater availability by altering the timing, location, and quantity of groundwater recharge and demand. Successful conjunctive use may require analysis with an integrated approach that accounts for the many interactions and feedbacks between surface-water and groundwater availability and their joint management. In order to improve simulation and analysis of conjunctive use, Bureau of Reclamation and USGS are collaborating to develop a surface-water operations module within MODFLOW One Water Hydrologic Flow Model (MF-OWHM), a new version of the USGS Modular Groundwater Flow Model (MODFLOW). Here we describe the development and application of the surface-water operations module. We provide an overview of the conceptual approach used to simulate surface-water operations-including surface-water storage, allocation, release, diversion, and delivery on monthly to seasonal time frames-in a fully-integrated manner. We then present results from a recent case study analysis of the Rio Grande Project, a large-scale irrigation project located in New Mexico and Texas, under varying surface-water operations criteria and climate conditions. Case study results demonstrate the importance of integrated hydrologic simulation of surface water and groundwater operations in analysis and management of conjunctive-use systems.

From our analysis of petroleum industry wells, we have found over 600 wells drilled on the Gulf of Mexico continental slope that penetrate the gas hydrate stability zone and contain well logs useful for appraising gas hydrate accumulations. We identify natural gas hydrate in petroleum industry wells based on an increase in resistivity of at least 0.5 ohm*m from the background resistivity. Using this criterion, we have identified at least 40 wells with gas hydrate occurrence. Some of these new prospects have significant hydrate accumulations. For example, in Alaminos Canyon Block 810 we found a natural gas hydrate accumulation with up to 10 ohm*m resistivity above the background resistivity and over 715 feet of hydrate. BSRs occur at many gas hydrate sites near the thermodynamic base of the gas hydrate stability zone, but, as many recent drilling expeditions have shown, drilling a BSR is not a guarantee of locating a natural gas hydrate accumulation. We will combine a comprehensive analysis of BSRs on the continental slope with our extensive basin-wide review of gas hydrate accumulations occurring in petroleum industry wells in this area. We will consider both traditional (also called continuous) BSRs, which are uninterrupted seismic events that mimic the seafloor and discontinuous BSRs which are disparate individual seismic events that usually appear along dipping strata. By combining these singular data sets, we will identify a relationship between BSR occurrences and gas hydrate accumulations in the northern Gulf of Mexico.

We are turning slowly toward "alternatives" such as municipal and industrial wastewater, saline groundwater, the sea, irrigation return flow, and produced water that comes up with oil and gas deposits from deep beneath the surface of the earth. Slowly turning, not because of a lack in technological ability, but because it takes a large capital investment to acquire and treat these sources to a level at which they can be used. The regulatory system is not geared up for alternative sources and treatment processes. Permitting can be circular, contradictory, time consuming, and very expensive. The purpose for the water, or the value of the product obtained using the water, must be such that the capital and ongoing expense seem reasonable. There are so many technological solutions for recovering water quality that choosing the most reliable, economical, and environmentally sound technology involves unraveling the "best" weave of treatment processes from a tangled knot of alternatives. Aside from permitting issues, which are beyond the topic for this presentation, the "best" weave of processes will be composed of four strands specifically fitted to the local situation: energy, pretreatment, driving force for separation processes, and waste management. A range of treatment technologies will be examined in this presentation with a focus on how the quality of the feed water, available power sources, materials, and waste management opportunities aid in choosing the best weave of treatment technologies, and how innovative use of a wide variety of driving forces are increasing the efficiency of treatment processes.

Thermal anomaly maps and estimates of the radiant geothermal heat flux are important for establishing the baseline thermal activity to better detect and understand future anomalous hydrothermal and/or volcanic activity, and also for monitoring changes in the geothermal system to support decisions regarding infrastructure development, preservation and protection of Yellowstone's resources, and ensuring visitor safety. One of the critical measurement parameters in the use of spaceborne TIR for studying subtle (sub-pixel, sub-boiling) thermal features is the acquisition of TIR data at night. Acquisition of night time data reduces the influence of solar radiance and increases the temperature difference between thermal targets and the cooler background, thus improving estimates of the geothermal component of heat flux. ASTER night time TIR data (90-m pixels) are acquired too infrequently and irregularly for regular monitoring purposes. However, the new Landsat 8 platform with the Thermal Infrared Sensor (100-m pixels) has been tasked to regularly collect night time TIR imagery (every 16 days). These data show promise for continued satellite-based thermal monitoring at Yellowstone, and could also be useful in monitoring subtle thermal activity at other volcanic/geothermal systems around the world. This presentation will highlight results of a comparative analysis of Landsat 8 TIRS and ASTER TIR data for measuring and mapping Yellowstone's thermal areas.

We analyzed sorbed metal concentrations, carbon, nitrogen, and organic matter to document past mining pollution in sediment cores recovered from McCargoe Cove; a long, narrow inlet of Lake Superior on Isle Royale adjacent to a high concentration of ancient copper mines. Concentrations of lead, copper, and potassium increase in the sediments at McCargoe Cove after 1860 AD and between 6500 and 5400 years before 1950 AD or present (yr BP). Metal pollution increases coincide with radiocarbon dates associated with prehistoric copper artifacts and mines. These results, in combination with other lake sediment reconstruction sites located on Michigan's Keweenaw Peninsula, demonstrate that from 6500 to 5400 yr BP mining activities are detectable across the Lake Superior region. Interestingly a coherent cessation of lead emissions at multiple study sites after approximately 5400 yr BP coincides with the onset of dry conditions found in regional paleoclimate proxy records. After approximately 5000 yr BP, lead concentrations on both Isle Royale and the Keweenaw Peninsula remain at background levels until the onset of modern pollution increases approximately 1860 AD.

The data were acquired with a 4-km swath width centered on the SAF, and many tectonic features are recorded in the imagery. Spectral analysis using diagnostic features of minerals can identify rocks, soils and vegetation. Mako imagery can also locate rupture zones and measure slip distances. Designed and built by The Aerospace Corporation, the innovative and highly capable airborne imaging spectrometer used for this work enables low-noise performance (NEDelta T less than or equivalent to 0.1 K * 10 mu m) at small pixel IFOV (0.55 mrad) and high frame rates, making possible an area-coverage rate of 20 km2 per minute with 2-m ground resolution from 12,500 ft (3.8 km) above-ground altitude. Since its commissioning in 2010, Mako has been used in numerous studies involving other earthquake fault systems (Hector Mine, S. Bristol Mts.), mapping of surface geology, geothermal sources (fumaroles near the Salton Sea), urban surveys, and the detection, quantification, and tracking of natural and anthropogenic gaseous emission plumes. Mako is available for airborne field studies and new applications are of particular interest. It can be flown at any altitude below 20,000 ft to achieve the desired GSD.

In addition, a number of regions and processes were identified where model-data discord was highest (e.g. tropical and mid-to-high latitude North Atlantic sea surface temperatures, and the model representation of polar amplification in general). One potential reason for data-model discrepancies may come from the inability of fixed boundary condition, equilibrium type climate model simulations to predict the full potential of climate variability expressed in the proxy records (e.g. due to changing orbital forcing). Therefore, transient models will be used to understand temporal and spatial variability between Marine Isotope Stage (MIS) M2 and KM5 ( nearly equal 3.3 Ma to 3.2 Ma), a key interval within the Pliocene. The Pliocene Research, Interpretation and Synoptic Mapping Project (PRISM4) has begun generation of high resolution multiple proxy time series to be used to verify simulated conditions in selected areas between MIS M2 and MIS KM5, including the PlioMIP2 KM5C time slice (3.205 Ma). We use the full-complexity intermediate-resolution FAMOUS climate model driven by PRISM3 boundary conditions and run experiments with time varying orbital forcing, but without dynamic vegetation initially. We perform a preliminary data-model comparison by point-wise assessing the FAMOUS simulations against the new PRISM4 SST data focusing on the North Atlantic, a region where PlioMIP1 GCM simulations and paleoenvironmental estimates exhibited the greatest amount of discord.

We placed broadband seismometers on each arch and recorded up to three hours of ambient seismic data. Identified spectral peaks are interpreted to represent resonant frequencies of the arches, and further studied for their polarization attributes. We developed 3D models of each site using ground-based photogrammetry in order to perform numerical modal analyses. Assigning representative material properties, we are able to match the measured fundamental frequency of each arch, as well as certain higher-order resonant frequencies. Landscape Arch is the longest arch in North America and is remarkably slender, while Double-O Arch is a prominent visitor attraction. Repeat ambient vibration measurements over time will be used to assess changes in resonance characteristics, which in turn provide evidence of internal mechanical change. Our goal is to understand how the arches respond to their environment, and ultimately be able to assess progressive damage of these iconic features.

Thermal cameras can sometimes "see" through volcanic fume that obscures views to visual webcams and the naked eye, and often provide a much clearer view of the extent of high temperature areas and activity levels. We describe a thermal camera network recently installed by the Hawaiian Volcano Observatory to monitor Kilauea's summit and east rift zone eruptions (at Halema'uma'u and Pu'u ''Aa craters, respectively) and to keep watch on Mauna Loa's summit caldera. The cameras are long-wave, temperature-calibrated models protected in custom enclosures, and often positioned on crater rims close to active vents. Images are transmitted back to the observatory in real-time, and numerous Matlab scripts manage the data and provide automated analyses and alarms. The cameras have greatly improved HVO's observations of surface eruptive activity, which includes highly dynamic lava lake activity at Halema'uma'u, major disruptions to Pu'u ''Aa crater and several fissure eruptions.

Each event was associated with rapid, 5-10 C warming throughout much of the northern hemisphere and a more gradual 2 C cooling in the southern hemisphere. Although much has been learned about the potential mechanisms involved, the ultimate source of the 1470-yr periodicity of this climate signal is undetermined. Five theories have been proposed so far. Each identifies a causal agent with the requisite periodicity and a general mechanism to explain how its behavior could have induced global-scale climate change. Proposed agents include the ocean-atmosphere itself, the sun, the moon and the geomagnetic field. Proposed mechanisms include systematic variation in the thermohaline circulation of the ocean ("salt oscillator"), the location of north Atlantic deepwater formation ("stochastic resonator"), the intensity of the El Nino Southern Oscillation ("super-ENSO"), the intensity of tidally-driven upwelling ("super-tide") and geomagnetically-induced cloud formation. This presentation lays the groundwork for the first theory to invoke the outer core. The theory identifies a causal agent with the requisite periodicity (the outer core's azimuthal flow) and describes how systematic variation in its motion could have affected ocean-atmosphere motion and thus global climate during the last glacial period. Five criteria are used to evaluate the proposed theory and compare its performance to the other theories. Some ways to further test the new theory using paleoproxy data and data for the contemporary climate system are described.

Since dam closure in 1962, the 2002 survey estimates an annual sedimentation rate of 153,000 m3/y, resulting in a 25% loss of total reservoir capacity. Long before sediment levels completely fill the reservoir, the outlet works have recently plugged with sediment and debris, adversely impacting operations, and emphasizing the urgency of formulating an effective sediment management plan. Starting in 2010-2011, operations were changed to lower the reservoir and flush sediment through the outlet works in early spring before filling the pool for irrigation. Even though the flushing strategy through the long, narrow reservoir ( approximately 5 km long and 0.3 km wide) has prevented outlet works plugging, a long term plan is needed to manage inflowing and deposited sediment more efficiently. Reclamation's Sedimentation and River Hydraulics Group is leading an effort to study the past and current sediment issues at Paonia Dam and Reservoir, evaluate feasible sediment management alternatives, and formulate a plan for future operations and monitoring. The study is building on previously collected data and the existing knowledge base to develop a comprehensive, sustainable sediment management plan. The study is being executed in three phases: Phase 1 consisted of an initial site visit to map and sample existing reservoir bottom sediments, a preliminary site evaluation upstream and downstream of the dam, and establishment of time-lapse photo sites and taking initial ground-based photos. Phase 2 includes a bathymetric survey of entire reservoir and 11 km of the river downstream of the dam, continuous suspended sediment monitoring upstream and downstream of the reservoir, and collection of additional core samples of reservoir bottom sediments. Phase 3 involves the evaluation of current and past operations and sediment management practices, evaluate feasible sediment management methods, and providing recommendations for future monitoring and sediment management operations. Data collected during Phases 1 and 2 are used in a one-dimensional numerical sediment transport model for evaluating past, current, and potential future sediment management options.

AN - 1722155210; 2015-097603 AB - Permafrost underlies approximately 70% of all National Park Service administered land in Alaska and it provides a stable foundation to parks' ecosystems and wildlife habitats. However, the strength of this foundation is waning as its temperature is rising in response to recent climate warming. Consequently, thermokarst activities are on the rise and they are altering the parks' landscape, ecosystems, and wildlife habitats. In order to effectively respond to these changes park managers need up-to-date knowledge of the current permafrost temperature and distribution, and how they might evolve with changing climate in the future. To help decision makers understand and respond to the changing permafrost condition, we are modeling near-surface permafrost dynamics-permafrost temperature, distribution, and active layer thickness-in eight national parks of Alaska at a decadal time scale. We are using GIPL 1.0 model (Spatially Distributed Model of Permafrost Dynamics in Alaska), the best available climate inputs, and high-resolution (28 m) ecotype, soil landscape, and snow inputs. Here we present results for two national parks-Denali National Park and Preserve (DENA) and Wrangell-St. Elias National Park and Preserve (WRST). Areas underlain by glaciers and permanent ice-fields were excluded. In DENA, the model suggested near-surface permafrost in 51% of the park area for the 2000 decade, predicted its decline to 6% by 2050s, and 1% by 2090s. In WRST, the model suggested near-surface permafrost in 72% of the park area for the 2000 decade, predicted its decline to 42% by 2050s, and 15% by 2090s. In summary, the near-surface permafrost will likely be degrading in most parts of DENA and WRST towards the end of the current century except at higher elevations where climate models continue to project colder temperature. The modeled maps of DENA and WRST showed 86% and 95% agreement with the field observations of permafrost presence/absence at 1375 and 430 sites, respectively. In conclusion, the modeled high-resolution permafrost maps show the effect of changing climate on near-surface permafrost. They offer decision makers a clear understanding of how near-surface permafrost distribution in the parks might change in the future, which was lacking up until now, to guide critical monitoring and management decisions.

Satellite data show it to be one of the most prolific sources of natural oil slicks in the entire GOM. We mapped its seafloor oil and gas vents with 3-D seismic, swath-bathymetry acoustics and submersible observations, documenting gas hydrate deposits, brine pools, benthic fauna, and authigenic carbonates. Geophysical profiles show subbottom locations of salt bodies and migration conduits. We deployed time-lapse imaging systems focused on individual vents to quantify release rates. Oil and gas flow upward along the flanks of an allochthonous salt body from source rocks at 10,000 m and migrate to the seafloor from faults emanating from the salt. Venting to the water column and surface consists of oily bubbles and occurs in two fields separated by approximately 1 km. The NW vent field (Megaplume) appears to be a more recent expression and hosts about three highly active vents; while the SE vent field (Birthday Candles) hosts more than 10 vents that are generally slower. We measured discharge rates of 2.6 cm3 s-1 and Megaplume and 0.09 cm3 s-1 at Birthday Candles. Although surface deposits of gas hydrate were evident at both vent fields, the Birthday Candles area featured dozens of conical mounds formed by gas hydrate that were dark brown due to large amounts of liquid oil perfused throughout the deposits. Large brine pools indicated gas hydrate formation at the seafloor. Venting occurred in horizontal fissures on the mounds, in which oil and hydrate combined to form short-lived chimneys and balloon-like structures. Ice worms (Hesiocaeca methanicola) were extremely abundant in burrows extending from the sediment into the gas hydrate. Proceeding farther to the SE, venting is reduced and absent, but surface carbonate deposits suggest relict gas hydrate mounds. We propose that the NW to SE trend at GC600 encompasses the progressive development of a biogeochemical filter that sequesters and mineralizes a very substantial portion of the source hydrocarbon prior to discharge into the water column.

Based on previously collected logging-while-drilling (LWD) borehole data, these gas hydrate study sites are known to include high concentrations of gas hydrate within sand layers. At GC955 our new 2D data reveal at least three features that appear to be fluid-flow pathways (chimneys) responsible for gas migration and thus account for some aspects of the gas hydrate distribution observed in the LWD data. Our new data also show that the main gas hydrate target, a Pleistocene channel/levee complex, has an areal extent of approximately 5.5 square kilometers and that a volume of approximately 3 X 107 cubic meters of this body lies within the gas hydrate stability zone. Based on LWD-inferred values and reasonable assumptions for net sand, sand porosity, and gas hydrate saturation, we estimate a total equivalent gas-in-place volume of approximately 8 X 108 cubic meters for the inferred gas hydrate within the channel/levee deposits. At WR313 we are able to map the thin hydrate-bearing sand layers in considerably greater detail than that provided by previous data. We also can map the evolving and migrating channel feature that persists in this area. Together these data and the emerging results provide valuable new insights into the gas hydrate systems at these two sites.

The entire margin has ruptured in megathrust earthquakes, including the M9.2 1964 event, and these earthquakes have launched deadly local and trans-Pacific tsunamis. Tsunamis have been by far the largest killer in these earthquakes. Moreover, the subduction zone displays a range in locking behavior from completely locked beneath Prince William Sound, to nearly freely slipping beneath the Shumagin Islands. Characterizing earthquake-related tsunami sources requires a diverse set of methods, and we discuss several examples. One important source for tsunamis is from megathrust splay faults. The Patton Bay splay fault system ruptured during the 1964 earthquake and generated a tsunami that impacted coastlines tens of minutes after the earthquake. A combination of multibeam mapping, high-resolution and crustal-scale seismic data, thermochronology, and detrital zircon geochronology show focused exhumation along this splay fault system for the last 2-3 Ma. Moreover, this long term pattern of exhumation mimics the pattern of uplift in 1964. Submarine landslides are another example of a tsunami source. Numerous devastating slides were triggered by the 1964 earthquake. Multibeam bathymetry, bathymetry difference maps, high-resolution seismic data, and records of paleotsunamis in coastal marshes reveal a long history of submarine landsliding in the coastal fjords of Alaska. The Little Ice Age appears to have had a significant influence on the submarine landslides in the 1964 earthquake through increased sediment production, transport to fjord margins, and, locally, compaction by glacier advances. Glacial retreat before 1964 gave rise to over-steepened slopes susceptible to dynamic failure. Numerous blocks in the submarine landslides were particularly effective in generating high tsunami run up. Finally, regional tectonic displacements of the seafloor have launched trans-Pacific tsunamis. Coastal evidence of high tsunamis in the eastern Aleutians has helped us understand the frequency of megathrust earthquakes west of Kodiak Island. Recent studies of vertical displacements produced by tsunamigenic earthquakes has led to new insights about the persistence of rupture boundaries and long term constraints on locking behavior.

Wilson Valley lies at the center of a tectonic pull-apart basin formed in the 2.5-km stepover between the Hunting Creek fault (northernmost section of the GVF) and the Highway-20 section of the BSF. A major regional drainage, Cache Creek flows through this depression and has been offset approximately 6 km right-laterally by the GVF-BSF during the Quaternary. We recently discovered the Kuikui fault, a dextral-oblique slip fault within the stepover, using high-resolution imagery from LiDAR acquired by USGS in 2011 along major northern California fault zones (ARRA11_USGS, DOI: 10.5069/G9H70CRD, http://dx.doi.org/10.5069/G9H70CRD). The Kuikui fault is approximately 2-3 km in length and forms steep, well-preserved scarps up to approximately 2.5 m high. It has only subtle expression of dextral slip, so its ratio of dip slip to strike slip is uncertain. Any evidence of large paleoearthquakes in the Wilson Valley stepover might indicate rupture of either the GVF or the BSF or both together, and timing information could be used to correlate events with other paleoseismic sites on the fault system. Additionally, fault creep has been documented on both the Highway 20 and Hunting Creek fault sections, so that any fault offset on the Kuikui fault might also include some aseismic slip. Because wilderness regulations required manual excavation, several participants from USGS, HSU, other colleagues and volunteers together dug an 8-m long by < or =1 m deep trench by hand to expose faulting in thin layers of alluvium deposited across the Kuikui fault. The youngest, and currently active soil layer is vertically offset by a minimum of 7 cm on a single fault strand. A much broader fault zone suggests larger movement has occurred. This exposure did not allow us to discriminate whether slip occurred as creep or by dynamic rupture. Future additional exposures may better distinguish evidence of creep from seismogenic ruptures. Pending radiocarbon dates may partially constrain when this slip occurred.

The Arctic is facing a major ecological transition that is expected to substantially affect animal and human health. Changes in phenology or environmental conditions that result from climate warming may promote novel species assemblages as host and pathogen ranges expand to previously unoccupied areas. Recent evidence from the Arctic and subarctic suggests an increase in the spread and prevalence of some wildlife diseases, but baseline data necessary to detect and verify such changes are still lacking. Wild birds are undergoing rapid shifts in distribution and have been implicated in the spread of wildlife and zoonotic diseases. Here, we review evidence of current and projected changes in the abundance and distribution of avian diseases and outline strategies for future research. We discuss relevant climatic and environmental factors, emerging host-pathogen contact zones, the relationship between host condition and immune function, and potential wildlife and human health outcomes in northern regions.

Ecosystem protection of permafrost is governed by the low thermal conductivity of organic soils, which is sensitive to changes in horizon thickness (OHT), moisture content, and decomposition extent (and thus, porosity, and density) of organic matter. At broad spatial scales, the occurrence of permafrost is positively correlated with OHT when organic horizons are relatively thin (<30 cm). Across sites where OHT is deeper, this correlation reverses and becomes negative. We hypothesize that this bi-modal relationship between OHT and permafrost occurrence is primarily governed by the contrasting thermal properties of upper organic-soil horizons and the underlying deep organic-soil and mineral-soil horizons. As documented with prior investigations on snow thermal properties, we find that that the underlying layers can have a profound impact on the insulating effect of the overlying layer. To evaluate this hypothesis, we examine the sensitivity of permafrost to soil properties (OHT, moisture content, and texture) and their variations across landscape positions and drainage class using field-based observations and generalized simulations using the Geophysical Institute Permafrost Laboratory model (GIPL). We observed significant negative correlations between minimum daily ground-surface temperature during summer and OHT across upland forest sites in interior Alaska. In peatlands, ground-surface temperature and OHT appear to be decoupled, which is likely due to variation in deposit thickness as determined by the timing of peatland formation across the region. Model results highlight the role of moisture content and water table position, both as controls on organic matter accumulation and on permafrost extent and thermal state.

This SOC is potentially vulnerable to remobilization following soil warming and permafrost thaw, but stock estimates are poorly constrained and quantitative error estimates were lacking. This study presents revised estimates of the permafrost SOC pool, including quantitative uncertainty estimates, in the 0-3 m depth range in soils as well as for deeper sediments (>3 m) in deltaic deposits of major rivers and in the Yedoma region of Siberia and Alaska. The revised estimates are based on significantly larger databases compared to previous studies. Compared to previous studies, the number of individual sites/pedons has increased by a factor 811 for 13 m soils, a factor 8 for deltaic alluvium and a factor 5 for Yedoma region deposits. A total estimated mean storage for the permafrost region of ca. 1300-1400 Pg with an uncertainty range of 1050-1650 Pg encompasses the revised estimates. Of this, 3 m depth deposits in deltas and the Yedoma region.

Permafrost thaw has dramatic consequences on local hydrology, ecology, and the carbon (C) balance of these ecosystems. The degree to which permafrost peatlands become C sources or sinks following permafrost thaw remains a topic of much debate, owing to the difficulty in accurately dating cores from collapse-scar bogs and in understanding the vulnerability of the formerly forested peat to decomposition immediately following thaw and inundation. Here we use a combination of a chronosequence, paleoenvironmental, and modeling approaches from a permafrost peat plateau interspersed with collapse-scar bogs in Interior Alaska to address how C storage is impacted on timescales from decades to millennia following permafrost thaw. Our initial results indicate that C stocks are lowest in young (years to decades) and intermediate (decades to centuries) collapse-scar bogs, but that net C stocks in old (centuries to millennia) bogs can be as high as in permafrost plateaus. Thawed forested plateau peat is subject to rapid decomposition in the years to decades following thaw, but that rate of loss slows over time. We hypothesize that this is because the labile C pool is preferentially consumed and quickly exhausted by soil microbes. Meanwhile, post-thaw collapse-scar bog peat accumulates rapidly at the surface, and our data show that on longer centennial to millennial timescales, this near-surface C may offset initial post-thaw losses at depth. Collapse-scar bog peat accumulation rates outpace the former-plateau peat loss in a matter of years to decades. Older landscapes (i.e., those that began accumulating peat many thousands of years ago), are subject to greater C loss following thaw than are younger landscapes(i.e., those that initiated only a couple thousand years ago), leading to a much longer period of net C loss from the ecosystem in older peatlands.

One way to constrain potential loss is to compare soils with and without permafrost. We compared three sets of soil profiles developed in late Pleistocene loess from various slope positions in western Iowa (no permafrost for >10 ka), south-central Alaska (no permafrost for >3550 y), and interior Alaska (current permafrost). In Iowa C where deep C was protected by loess burial, % soil C declined most precipitously with depth (down to <0.6%C at 1 m). Alaska soils with and without permafrost were similar in %C at 1 m depths (up to 2%C). However soils with permafrost had 2X to 4X more C than non-permafrost soils at 1.5 m and maintained high and highly variable (0.8 to 11%C) C contents below 150 cm. Data provide an additional line of evidence that carbon in deep permafrost is highly susceptible to loss upon thawing. Meanwhile modeling and forecasting C fate requires more insight into C protection and stabilization by burial.

We hypothesize that inconsistent application of a complete diagnostic approach to coral disease has contributed to this slow progress. We quantified methods used to investigate coral disease in 492 papers published between 1965 and 2013. Field surveys were used in 65% of the papers, followed by biodetection (43%), laboratory trials (20%), microscopic pathology (21%), and field trials (9%). Of the microscopic pathology efforts, 57% involved standard histopathology at the light microscopic level (12% of the total investigations), with the remainder dedicated to electron or fluorescence microscopy. Most (74%) biodetection efforts focused on culture or molecular characterization of bacteria or fungi from corals. Molecular and immunological tools have been used to incriminate infectious agents (mainly bacteria) as the cause of coral diseases without relating the agent to specific changes in cell and tissue pathology. Of 19 papers that declared an infectious agent as a cause of disease in corals, only one (5%) used microscopic pathology, and none fulfilled all of the criteria required to satisfy Koch's postulates as applied to animal diseases currently. Vertebrate diseases of skin and mucosal surfaces present challenges similar to corals when trying to identify a pathogen from a vast array of environmental microbes, and diagnostic approaches regularly used in these cases might provide a model for investigating coral diseases. We hope this review will encourage specialists of disease in domestic animals, wildlife, fish, shellfish, and humans to contribute to the emerging field of coral disease.

Surveys were conducted during 2000-2009 at 150 unique streams and lakes within the San Gabriel, San Bernardino, San Jacinto, and Palomar mountains of southern California. Only nine small, geographically isolated populations were detected across the four mountain ranges, and all tested positive for the amphibian chytrid fungus Batrachochytrium dendrobatidis . Our data show that when R. muscosa is known to be present it is easily detectable (89%) in a single visit during the frog's active season. We estimate that only 166 adult frogs remained in the wild in 2009. Our research indicates that R. muscosa populations in southern California are threatened by natural and stochastic events and may become extirpated in the near future unless there is some intervention to save them.

Two ANN-based control logic systems and two conventional rule-based logic systems were developed to control a heating device and the openings of a double skin enveloped building. The ANN-based logic controls heating devices on a continuous basis according to the indoor temperature. The rule-based logic controls heating systems and openings at envelopes in two-position on/off operation. Control performance for the developed logic was numerically conducted using computer simulations for a small office space with double skin envelopes during the heating season. Analysis results indicate that the ANN-based temperature control logic resulted in a more stable temperature near the center of the comfortable range with a reduced opening period of the internal envelope. The reduced number of on/off moments of the heating device and the openings in the ANN-based logic were predicted to save energy and prevent system degradation. The use of ANN-based logic would be effective for maintaining a stable thermal environment and for system operation. Rule-based logic can be effectively used to improve building energy efficiency. In this study, two ANN-based logic types were developed for heating devices controlled on a continuous basis and their performance was compared with those of rule-based on/off logic. Thus, in order to cover the limitation of this study, further study is warranted for examining the clear difference achieved by ANN-based vs. rule-based control, when they are applied to control heating output on a continuous basis.

However, it is a challenge to make a model utilize the open and growing functions (e.g., model inversion) on the R platform due to the requirement of accessing and revising the model's source code. To overcome this barrier, we developed a universal tool that aims to convert a model developed in any computer language to an R function using the template and instruction concept of the Parameter ESTimation program (PEST) and the operational structure of the R-Soil and Water Assessment Tool (R-SWAT). The developed tool (Model-R Coupler) is promising because users of any model can connect an external algorithm (written in R) with their model to implement various model behavior analyses (e.g., parameter optimization, sensitivity and uncertainty analysis, performance evaluation, and visualization) without accessing or modifying the model's source code.

This study examined the relationship between N-cycling processes in bed sediments and N speciation and loading in the Yukon River near its mouth at the Bering Sea. We conducted laboratory bioassays to measure N-cycling processes in sediment samples collected over distinct water cycle seasons. In conjunction, the microbial community composition in the bed sediments using genes involved in N-cycling (narG, napA, nosZ, and amoA) and 16S rRNA gene pyrosequences was examined. Temporal variation was observed in net N mineralization, nitrate uptake, and denitrification rate potentials and correlated strongly with sediment carbon (C) and extractable N content and microbial community composition rather than with river water nutrient concentrations. The C content of the bed sediment was notably impacted by the spring flood, ranging from 1.1% in the midst of an ice-jam to 0.1% immediately after ice-out, suggesting a buildup of organic material (OM) prior to scouring of the bed sediments during ice break up. The dominant members of the microbial community that explained differences in N-processing rates belonged to the genera Crenothrix, Flavobacterium, and the family of Comamonadaceae. Our results suggest that biogeochemical processing rates in the bed sediments appear to be more coupled to hydrology, nutrient availability in the sediments, and microbial community composition rather than river nutrient concentrations at Pilot Station. Key Points * Bed sediment scouring during ice-out governs sediment biogeochemical processes * N-cycling rates relate to sediment C and N and microbial community composition * Sediment microbial community controlled by seasonal scouring and deposition JF - Journal of Geophysical Research.

We used terrestrial laser scanning (TLS) to characterize and quantify the rocky intertidal zone topography at a western U.S. coastal site (Rabbit Rock, Oregon) to support ecological research relating to potential climate-induced changes in distribution and abundance of intertidal invertebrates and a large-bodied shorebird, the Black Oystercatcher (Haematopus bachmani). Alternate available data (e.g., aerial photography, airborne LIDAR) proved inadequate or infeasible for development of a topographic surface model inclusive of intertidal area from Mean Lower Low Water to Mean Higher High Water tidal elevation. Our TLS-derived topographic surface model competently supported development of an invertebrate distribution model relative to tidal elevation and topography. Using the developed model, we estimated current and future aerial extent of the intertidal zone and potential foraging habitat for Black Oystercatcher in our study area. Intertidal zone area decreased from 7,194 m super(2) to 6,409 m super(2) and 3,070 m super(2) with 1 and 2 m sea-level rise, respectively. Surprisingly, due to the configuration of site substrate, potential foraging habitat for Black Oystercatcher increased from 5,658 to 5,903 m super(2) with 1 m sea-level rise, but declined to 3,068 m super(2) with 2 m sea-level rise. Our results demonstrate the utility of TLS for ecological research in the rocky intertidal zone. They further illustrate that climate change effects on ecological conditions may vary considerably depending on local configurations.

Palila are morphologically and behaviorally adapted to consume mamane seeds by grasping seed pods with their feet and opening pods with stout bills and demonstrate limited ability to exploit alternative food resources. This degree of single species dependency is rare among birds and illustrates unique adaptations that also occurred in other Hawaiian species that are now extinct. In mixed-woodland with co-dominant naio (Myoporum sandwicense), Palila spent 1.7-3.9 times longer in mamane than in naio during foraging observations where naio was 1.3-4.6 times as dense as mamane. Naio fruit was readily available, but it comprised proportionally <11% of food items taken by Palila. Although mamane flowers were more abundant than mamane pods throughout this study except at one lower-elevation mixed-woodland site, Palila spent more time foraging on pods than flowers in both mamane woodland and mixed-woodland, but consumed more flowers than pods in mixed-woodland. Insects, which have been reported as an important component of the diet of Palila, were apparently taken rarely in this study. Protecting and restoring mamane in woodlands adjacent to the current range of Palila will benefit their recovery, allowing them to exploit increased food availability in areas of their former range.

There was no indication of changes in PCB congener patterns over the incubation period in tree swallows in 1999 and 2000 at a site with very high PCB exposure or a site with more modest PCB exposure. Additionally, congeners known to be either quickly metabolized or conserved based on experimental studies did not generally respond as predicted. Similarly, PCB congener patterns in eggs of little terns from Bottsand, Schleswig-Holstein, Germany, did not differ between non-incubated and embryonated eggs. The results from both species suggest that the stage of incubation is not an important consideration when evaluating PCB congener patterns; comparisons and assessments can be made with eggs collected at all stages of incubation.

In collaboration with scientists and resource managers from numerous agencies and institutions in the United States, Mexico, and Canada, the framework has been expanded to cover North America, and the original ecoregions (now termed Level III) have been refined, subdivided, and aggregated to identify coarser as well as more detailed spatial units. The most generalized units (Level I) define 10 ecoregions in the conterminous U.S., while the finest-scale units (Level IV) identify 967 ecoregions. In this paper, we explain the logic underpinning the approach, discuss the evolution of the regional mapping process, and provide examples of how the ecoregions were distinguished at each hierarchical level. The variety of applications of the ecoregion framework illustrates its utility in resource assessment and management.

We established 240 1-ha plots using random sampling, with 80 plots on each of the three types of managed lands. We conducted surveys in spring 2011 and collected data on live tortoises, shell-skeletal remains, other signs of tortoises, perennial vegetation, predators, and evidence of human use. Throughout the study area and regardless of management area, tortoise abundance was positively associated with one of the more diverse associations of perennial vegetation. The management area with the longest history of protection, a fence, and legal exclusion of livestock and vehicles had significantly more live tortoises and lower death rates than the other two areas. Tortoise presence and abundance in this protected area had no significant positive or negative associations with predators or human-related impacts. In contrast, the management area with a more recent exclusion of livestock, limited vehicular traffic, and with a recent, partial fence had lower tortoise densities and high death rates. Tortoise abundance here was negatively associated with vehicle tracks and positively associated with mammalian predators and debris from firearms. The management area with the least protection-unfenced, with uncontrolled vehicle use, sheep grazing, and high trash counts-also had low tortoise densities and high death rates. Tortoise abundance was negatively associated with sheep grazing and positively associated with trash and mammalian predator scat.

We hypothesized that controls over spatial variation in DOM quantity and composition (measured with DOM optical properties) differ based on the source of DOM to aquatic ecosystems. DOM quantity and composition should be better predicted by land cover in aquatic habitats with allochthonous DOM and related more strongly to nutrients in aquatic habitats with autochthonous DOM. Three habitat types [rivers (R), rivermouths (RM), and the nearshore zone (L)] associated with 23 tributaries of the Laurentian Great Lakes were sampled to test this prediction. Evidence from optical indices suggests that DOM in these habitats generally ranged from allochthonous (R sites) to a mix of allochthonous-like and autochthonous-like (L sites). Contrary to expectations, DOM properties such as the fluorescence index, humification index, and spectral slope ratio were only weakly related to land cover or nutrient data (Bayesian R super(2) values were indistinguishable from zero). Strongly supported models in all habitat types linked DOM quantity (that is, dissolved organic carbon concentration [DOC]) to both land cover and nutrients (Bayesian R super(2) values ranging from 0.55 to 0.72). Strongly supported models predicting DOC changed with habitat type: The most important predictor in R sites was wetlands whereas the most important predictor at L sites was croplands. These results suggest that as the DOM pool becomes more autochthonous-like, croplands become a more important driver of spatial variation in DOC and wetlands become less important.

This effort revealed taxonomic, geographic and ecological disparities in studies of amphibian populations in this region. Of the species of anurans and caudates known to occur in the Southeast, 73.8 and 33.3 %, respectively, have been monitored continuously for at least 4 years. Anurans are generally shorter-lived than are caudates and, thus, have been studied for the equivalent of at least one population turnover more than have caudates. The percentage of species (of those occurring in a given state) monitored continuously for at least 4 years was lowest for Alabama and Mississippi and highest for Florida for both taxa. The vast majority of studies (69.6 %) were conducted on species that inhabit natural freshwater wetlands, in contrast to other aquatic and terrestrial habitats. Species considered threatened by the International Union for Conservation of Nature comprised only 7.7 % of 65 species that have been studied consistently. The majority of comparative studies of contemporary versus historical occurrences were potentially biased by the use of "presence-only" historical data and resurveys of short duration. Other issues, such as inadequate temporal and spatial scale and neglect of different sources of error, were common. Awareness of these data gaps and sampling and statistical issues may help facilitate informed decisions in setting future monitoring priorities, particularly with respect to species, habitats and locations that have been largely overlooked in past and ongoing studies.

According to standard protocols, multiple segments are selected in a body of water to monitor population relative abundance as the ratio of total catch to total sampling effort. The standard protocol provides an assessment of fish distribution at a macrohabitat scale among segments, but not within segments. An ancillary protocol was developed for assessing fish distribution at a finer scale within electrofishing segments. The ancillary protocol was used to estimate spacing, dispersion, and association of two species along shore segments in two local reservoirs. The added information provided by the ancillary protocol may be useful for assessing fish distribution relative to fish of the same species, to fish of different species, and to environmental or habitat characteristics.

To evaluate restoration success, baseline conditions need to be determined and a reference target needs to be established that will serve as an ecological blueprint in the restoration process. During the summer wet seasons of 2010 and 2011, we used automated recording units to monitor a community of calling anuran amphibians in the Picayune Strand State Forest of Southwest Florida, USA. This area is undergoing hydrological restoration as part of the Comprehensive Everglades Restoration Plan. We compared occurrence of anurans at sites in the restoration area, to nearby locations in relatively undisturbed habitat (reference sites). We assessed the utility of the latter as restoration targets, using a hierarchical model of community species occupancy to estimate the probability of occurrence of anurans in restoration and reference locations. We detected 14 species, 13 of which were significantly more likely to occur in reference areas. All 14 species were estimated by our model to occur at these sites but, across both years, only 8-13 species were estimated to occur at restoration sites. The composition and structure of these habitats within and adjacent to the Picayune Strand State Forest indicate that they are suitable targets for habitat restoration, as measured by amphibian occurrence and species richness. These areas are important sources for recolonization of anuran amphibians as the hydrologically degraded Picayune Strand undergoes restoration to mitigate the effects of overdrainage and habitat loss.

Previous research demonstrated that this population is genetically unique, with a high proportion of unique mitochondrial DNA (mtDNA) haplotypes and with significant differences in microsatellite allele frequencies compared to populations across the species' range. As a result, this population was considered a distinct population segment (DPS) and was recently proposed for listing as threatened under the U.S. Endangered Species Act. A more comprehensive understanding of the boundaries of this genetically unique population (where the Bi-State population begins) and an examination of genetic structure within the Bi-State is needed to help guide effective management decisions. We collected DNA from eight sampling locales within the Bi-State (N = 181) and compared those samples to previously collected DNA from the two most proximal populations outside of the Bi-State DPS, generating mtDNA sequence data and amplifying 15 nuclear microsatellites. Both mtDNA and microsatellite analyses support the idea that the Bi-State DPS represents a genetically unique population, which has likely been separated for thousands of years. Seven mtDNA haplotypes were found exclusively in the Bi-State population and represented 73 % of individuals, while three haplotypes were shared with neighboring populations. In the microsatellite analyses both STRUCTURE and FCA separate the Bi-State from the neighboring populations. We also found genetic structure within the Bi-State as both types of data revealed differences between the northern and southern part of the Bi-State and there was evidence of isolation-by-distance. STRUCTURE revealed three subpopulations within the Bi-State consisting of the northern Pine Nut Mountains (PNa), mid Bi-State, and White Mountains (WM) following a north-south gradient. This genetic subdivision within the Bi-State is likely the result of habitat loss and fragmentation that has been exacerbated by recent human activities and the encroachment of singleleaf pinyon (Pinus monophylla) and juniper (Juniperus spp.) trees. While genetic concerns may be only one of many priorities for the conservation and management of the Bi-State greater sage-grouse, we believe that they warrant attention along with other issues (e.g., quality of sagebrush habitat, preventing future loss of habitat). Management actions that promote genetic connectivity, especially with respect to WM and PNa, may be critical to the long-term viability of the Bi-State DPS.

Architectural interventions in these buildings range from signage to interactive touch screens to gardens and demonstration kitchens that foster educational programmes about sustainable food. The result can be a building that offers informal education, support for formal environmental education, and, overall, a chance for students to embody sustainable living in their daily lives at school. To date, this type of building has been weakly theorized, and the relationship between architectural interventions and environmental education largely unexplored in the literature. This literature review weaves together theories that connect the physical environment with human factors. In particular, research in environmental education, museum studies, conservation psychology and architecture illuminates ways in which buildings can support environmental education and with tactics that go well beyond the convention of informational signage on the wall. The result of the literature review is a framework that points to design patterns that extend from passive to active, individual to collective, and formal to informal. This framework can inform the design, use and evaluation of school buildings designed with pedagogical intent.

High temporal resolution hydroacoustic and physical/chemical data were collected at two sites in Great Salt Lake (GSL), a saline lake in the western USA, to understand how density stratification may influence salinity and mercury (Hg) distributions. The first study site was in a causeway breach where saline water from GSL exchanges with less saline water from a flow restricted bay. Near-surface-specific conductance values measured in water at the breach displayed a good relationship with both flow and wind direction. No diurnal variations in the concentration of dissolved (<0.45 mu m) methylmercury (MeHg) were observed during the 24-h sampling period; however, the highest proportion of particulate Hg sub(total) and MeHg loadings was observed during periods of elevated salinity. The second study site was located on the bottom of GSL where movement of a high-salinity water layer, referred to as the deep brine layer (DBL), is restricted to a naturally occurring 1.5-km-wide "spillway" structure. During selected time periods in April/May, 2012, wind-induced flow reversals in a railroad causeway breach, separating Gunnison and Gilbert Bays, were coupled with high-velocity flow pulses (up to 55 cm/s) in the DBL at the spillway site. These flow pulses were likely driven by a pressure response of highly saline water from Gunnison Bay flowing into the north basin of Gilbert Bay. Short-term flow reversal events measured at the railroad causeway breach have the ability to move measurable amounts of salt and Hg from Gunnison Bay into the DBL. Future disturbance to the steady state conditions currently imposed by the railroad causeway infrastructure could result in changes to the existing chemical balance between Gunnison and Gilbert Bays. Monitoring instruments were installed at six additional sites in the DBL during October 2012 to assess impacts from any future modifications to the railroad causeway.

AN - 1808372950; 21029312 AB - A large database of ground motions from shallow earthquakes occurring in active tectonic regions around the world, recently developed in the Pacific Earthquake Engineering Center's NGA-West2 project, has been used to investigate what such a database can say about the properties and processes of crustal fault zones. There are a relatively small number of near-rupture records, implying that few recordings in the database are within crustal fault zones, but the records that do exist emphasize the complexity of ground-motion amplitudes and polarization close to individual faults. On average over the whole data set, however, the scaling of ground motions with magnitude at a fixed distance, and the distance dependence of the ground motions, seem to be largely consistent with simple seismological models of source scaling, path propagation effects, and local site amplification. The data show that ground motions close to large faults, as measured by elastic response spectra, tend to saturate and become essentially constant for short periods. This saturation seems to be primarily a geometrical effect, due to the increasing size of the rupture surface with magnitude, and not due to a breakdown in self similarity.

Following the shift to a warmer, wetter climate after the Last Glacial Maximum (LGM) ( approximately 18 ka), the Waipaoa River (New Zealand) rapidly incised up to 120 meters, leaving perched, low-relief hillslopes unadjusted to that base level fall. In the Mangataikapua-a 16.5 km (super 2) tributary principally composed of weak melange-pervasive post-LGM landslides responded to >50 m of fluvial incision by sculpting and denuding >99% of the catchment. By reconstructing LGM and younger paleosurfaces from tephra identified by electron microprobe analysis (EMPA) and lidar-derived surface roughness, we estimate the volume, timing, and distribution of hillslope destabilization in the Mangataikapua and the relative contribution of landslide-prone terrain to post-LGM landscape evolution. We calculate volume change between four paleosurfaces constrained by tephra age (Rerewhakaaitu, 17.5 ka; Rotoma, 9.4 ka; Whakatane, 5.5 ka; and Waimihia, 3.4 ka). From the paleosurface reconstructions, we calculate the total post-LGM hillslope sediment contribution from the Mangataikapua catchment to be 0.5 + or - 0.06 (s.d.) km (super 3) , which equates to a subcatchment averaged erosion rate of approximately 1.6 mm yr (super -1) . This is double the previous hillslope volume when normalized by study area, demonstrating that landslide-prone catchments disproportionately contribute to the terrestrial post-LGM sediment budget. Finally, we observe particularly rapid post-Waimihia erosion rates, likely impacted by human settlement. Abstract Copyright (2014), . American Geophysical Union. All Rights Reserved.

The prototype system, developed for the California coast, uses the global WAVEWATCH III wave model, the TOPEX/Poseidon satellite altimetry-based global tide model, and atmospheric-forcing data from either the US National Weather Service (operational mode) or Global Climate Models (future climate mode), to determine regional wave and water-level boundary conditions. These physical processes are dynamically downscaled using a series of nested Delft3D-WAVE (SWAN) and Delft3D-FLOW (FLOW) models and linked at the coast to tightly spaced XBeach (eXtreme Beach) cross-shore profile models and a Bayesian probabilistic cliff failure model. Hindcast testing demonstrates that, despite uncertainties in preexisting beach morphology over the approximately 500 km alongshore extent of the pilot study area, CoSMoS effectively identifies discrete sections of the coast (100s of meters) that are vulnerable to coastal hazards under a range of current and future oceanographic forcing conditions, and is therefore an effective tool for operational and future climate scenario planning.

The flux and composition of dissolved organic matter (DOM) from soils to rivers are sensitive to permafrost configuration and its impact on subsurface hydrology and groundwater discharge. Here, we evaluate the utility of DOM composition and age as a tool for detecting permafrost thaw in three rivers (Beaver, Birch, and Hess Creeks) within the discontinuous permafrost zone of interior Alaska. We observed strong temporal controls on Delta (super 14) C content of hydrophobic acid isolates (Delta (super 14) C-HPOA) across all rivers, with the most enriched values occurring during spring snowmelt (75 + or - 8 ppm) and most depleted during winter flow (-21 + or - 8 ppm). Radiocarbon ages of winter flow samples ranged from 35 to 445 yr BP, closely tracking estimated median base flow travel times for this region (335 years). During spring snowmelt, young DOM was composed of highly aromatic, high molecular-weight compounds, whereas older DOM of winter flow had lower aromaticity and molecular weight. We observed a significant correlation between Delta (super 14) C-HPOA and UV absorbance coefficient at 254 nm (alpha (sub 254) ) across all study rivers. Using alpha (sub 254) as an optical indicator for Delta (super 14) C-HPOA, we also observed a long-term decline in alpha (sub 254) during maximum annual thaw depth over the last decade at the Hess Creek study site. These findings suggest a shift in watershed hydrology associated with increasing active layer thickness. Further development of DOM optical indicators may serve as a novel and inexpensive tool for detecting permafrost degradation in northern watersheds. Abstract Copyright (2014), .

Where found, they provide insight into how the coupling of the ocean-atmosphere system is manifested in biotic and environmental records and how the biosphere responds to climate change. In 2010-2011, construction at Ziegler Reservoir near Snowmass Village, Colorado (USA) revealed a nearly continuous, lacustrine/wetland sedimentary sequence that preserved evidence of past plant communities between approximately 140 and 55 ka, including all of MIS 5. At an elevation of 2705 m, the Ziegler Reservoir fossil site also contained thousands of well-preserved bones of late Pleistocene megafauna, including mastodons, mammoths, ground sloths, horses, camels, deer, bison, black bear, coyotes, and bighorn sheep. In addition, the site contained more than 26,000 bones from at least 30 species of small animals including salamanders, otters, muskrats, minks, rabbits, beavers, frogs, lizards, snakes, fish, and birds. The combination of macro- and micro-vertebrates, invertebrates, terrestrial and aquatic plant macrofossils, a detailed pollen record, and a robust, directly dated stratigraphic framework shows that high-elevation ecosystems in the Rocky Mountains of Colorado are climatically sensitive and varied dramatically throughout MIS 5.

We monitored precipitation, overland flow, soil moisture, and headcut migration over several seasonal cycles at two adjacent rangeland channel heads in southern Arizona. Erosion occurred by headward retreat of vertical to overhanging faces, driven dominantly by surface runoff. No evidence exists for erosion caused by shallow-groundwater-related processes, even though similar theater-headed morphologies are sometimes attributed to seepage erosion by emerging groundwater. At our field site, vertical variation in soil shear strength influenced the persistence of the characteristic theater-head form. The dominant processes of erosion included removal of grains and soil aggregates during even very shallow (1-3 cm) overland flow events by runoff on vertical to overhanging channel headwalls, plunge-pool erosion during higher-discharge runoff events, immediate postrunoff wet mass wasting, and minor intra-event dry mass wasting on soil tension fractures developing subparallel to the headwall. Multiple stepwise linear regression indicates that the migration rate is most strongly correlated with flow duration and total precipitation and is poorly correlated with peak flow depth or time-integrated flow depth. The studied channel heads migrated upslope with a self-similar morphologic form under a wide range of hydrological conditions, and the most powerful flash floods were not always responsible for the largest changes in landscape form in this environment.

To resolve such a conflict in the Critical Habitat of the endangered Hawaiian honeycreeper, palila (Loxioides bailleui), federal courts ordered the eradication of introduced ungulates responsible for damaging the mamane (Sophora chrysophylla) forest on which palila depend. During 1980-2011, a total of 18,130 sheep (Ovis aries and O. gmelini musimon) and 310 goats (Capra hircus) were removed from Palila Critical Habitat (PCH) primarily by public hunters (54%) and secondarily by aerial shooting. Nevertheless, our analysis indicates that ungulates have increased over time. Palila numbers have declined sharply since 2003 due to long-term habitat degradation by ungulates and drought. Although culling ungulate populations has allowed some habitat improvement, their complete removal is necessary for palila to recover, especially given the potential for continued drought. Introduced predators are being controlled to reduce palila mortality, mamane and other native trees are being planted to restore some areas, and fencing is being constructed to prevent ungulate immigration. Funds are recently available for more effective eradication efforts, which are urgently needed to eliminate browsing damage in PCH and protect the palila from extinction.

Nest survival varied broadly among sites and years; annual estimates (lower, upper 95% confidence interval) ranged from 0.09 (0.03, 0.29) at Cape Espenberg in 2001 to 0.93 (0.76, 0.99) at the Copper River Delta in 2002. Annual variation among sites was not concordant, suggesting that site-scale factors had a strong influence on nest survival. Models of nest survival indicated that visits to monitor nests had a negative effect on nest daily survival probability, which if not accounted for biased nest survival strongly downward. The sensitivity of breeding Red-throated Loons to nest monitoring suggests other sources of disturbance that cause incubating birds to flush from their nests may also reduce nest survival. Nest daily survival probability at the Yukon-Kuskokwim Delta was negatively associated with an annual index of fox occurrence. Survival through the incubation and chick-rearing periods on the Yukon-Kuskokwim Delta ranged from 0.09 (0.001, 0.493) to 0.50 (0.04, 0.77). Daily survival probability during the chick-rearing period was lower for chicks that had a sibling in 2 of 3 years, consistent with the hypothesis that food availability was limited. Estimates of annual productivity on the Yukon-Kuskokwim Delta ranged from 0.17 to 1.0 chicks per pair. Productivity was not sufficient to maintain population stability in 2 of 3 years, indicating that nest depredation by foxes and poor foraging conditions during chick rearing can have important effects on productivity.

We used a two-state open robust design model to analyze a 14-year dataset (1998-2011) from the St. Joseph Peninsula, Florida (USA; 29.748 degree , -85.400 degree ) which is the densest loggerhead (Caretta caretta) nesting beach in the Northern Gulf of Mexico subpopulation. For these analyses, 433 individuals were marked of which only 7.2 % were observed re-nesting in the study area in subsequent years during the study period. Survival was estimated at 0.86 and is among the highest estimates for all subpopulations in the Northwest Atlantic population. The robust model estimated a nesting assemblage size that ranged from 32 to 230 individuals each year with an annual average of 110. The model estimates indicated an overall population decline of 17 %. The results presented here for this nesting group represent the first estimates for this subpopulation. These data provide managers with information specific to this subpopulation that can be used to develop recovery plans and conduct subpopulation-specific modeling exercises explicit to the challenges faced by turtles nesting in this region.

Upstream fish migration can be blocked or guided without physical structure by electrifying the water, but directional downstream fish guidance with electricity has received little attention. We tested two non-uniform pulsed direct current electric systems, each having different electrode orientations (vertical versus horizontal), to determine their ability to guide out-migrating juvenile sea lamprey (Petromyzon marinus) and rainbow trout (Oncorhynchus mykiss). Both systems guided significantly more juvenile sea lamprey to a specific location in our experimental raceway when activated than when deactivated, but guidance efficiency decreased at the highest water velocities tested. At the electric field setting that effectively guided sea lamprey, rainbow trout were guided by the vertical electrode system, but most were blocked by the horizontal electrode system. Additional research should characterize the response of other species to non-uniform fields of pulsed DC and develop electrode configurations that guide fish over a range of water velocity.

As part of our analysis, we compared characteristics of lead poisoned eagles with those that died of other causes. Odds of lead poisoning were greater for bald eagles versus golden eagles, females versus males, adults versus juveniles, and eagles from the Mississippi and Central flyways versus the Atlantic and Pacific flyways. In addition to spatial, species, and demographic associations, we detected a distinct temporal trend in the collection date of lead poisoned bald eagle carcasses. These carcasses were found at greater frequency in late autumn and winter than spring and summer. Lesions in lead poisoned birds included emaciation, evidence of bile stasis, myocardial degeneration and necrosis, and renal tubular nephrosis and necrosis. Ingested lead ammunition or fragments were found in 14.2 % of bald eagles and 11.8 % of golden eagles. The overall mean liver lead concentration (wet weight basis) for eagles diagnosed with lead poisoning was 28.9 plus or minus 0.69 SE mg/kg in bald eagles and 19.4 plus or minus 1.84 SE mg/kg in golden eagles. In eagles diagnosed with collision trauma, electrocution, poisoning (other than lead), emaciation, infectious disease, trapping death, other, and undetermined causes, average liver lead concentrations were low (<1 mg/kg) and did not differ among causes of mortality. Thus, based on our data, we found no evidence that lead exposure of eagles predisposed them to other causes of mortality.
