TY - JOUR T1 - Dietary assimilation of cadmium associated with bacterial exopolymer sediment coatings by the estuarine amphipod Leptocheirus plumulosus: effects of Cd concentration and salinity AN - 17418839; 4634187 AB - Bacterial extracellular substances (also known as exopolysaccharides, or EPS) may serve as vectors for trophic transfer of metals in benthic systems because these ubiquitous sediment coatings can sorb high concentrations of toxic metals, and because many benthic invertebrates assimilate EPS sediment coatings upon ingestion. We conducted 3 sets of experiments to determine the assimilative bioavailability of EPS-associated Cd to the benthic amphipod Leptocheirus plumulosus as a function of Cd concentration and salinity. Bioavailability was measured as L. plumulosus Cd assimilation efficiency (AE) from EPS-coated silica (EPS-Si) and from uncoated silica (NC-Si) using modified pulse-chase methods with the gamma-emitting radioisotope super(109)Cd. Cd AE was significantly greater from NC-Si than from EPS-Si at 7.5 ppt, but not at 2.5 or 25 ppt. Overall, Cd AE from EPS-Si was between 15.1 and 21.5%. Because EPS-Si sorbed more Cd than NC-Si, EPS coatings magnified the amount of Cd amphipods accumulated at each salinity by up to a factor of 10. Salinity did not directly affect Cd AE from EPS-Si, but because Cd-EPS partitioning increased with decreasing salinity, amphipods accumulated more Cd from EPS at the lowest Cd-EPS incubation salinity (2.5 ppt) than at higher salinities (7.5 and 25 ppt). Finally, Cd concentration in EPS exhibited an inverse relationship with Cd AE at 2.5 ppt, but not at 25 ppt. Specifically, Cd AE was 12 times greater at 1 compared with 10 mu g Cd mu g super(-1) EPS. Together, these results show that estuarine benthos can accumulate Cd from EPS sediment coatings, but that the degree to which this phenomenon occurs is dependent upon seawater salinity and Cd concentration in EPS.

AN - 70011217; 10472136 AB - The chemical analysis of intestinal digesta from hunter-killed carcasses or of wildlife scat is a promising means of estimating the exposure of wildlife to those environmental contaminants that, like lead, are poorly absorbed in the digestive tract. When evaluating contaminants at a site, biologists may find the results of this non-destructive approach more straightforward to interpret in terms of exposure to wildlife than would be analyses of soils, sediments, water, or wildlife tissues. To illustrate the approach, we collected digesta from 47 waterfowl shot by hunters at Prime Hook National Wildlife Refuge, in Delaware, USA. The waterfowl digesta contained an average of approximately 2.4% sediment, estimated from the Al concentrations in the digesta, a marker for sediment. Al concentrations were significantly correlated with concentrations of Cr (Spearman's rank correlation coefficient, r = 0.57), V (r = 0.70), Ni (r = 0.31), and Pb (r = 0.55), and we concluded that these metals were ingested mainly with sediment. American widgeon (Anas americana) ingested sediment at a rate of about four times that of three other species of dabbling ducks (Anas crecca, A. acuta, A. rubripes) and had several times the exposure to the sediment-associated metals. The digesta of one American black duck contained a high concentration of lead (70 mg/kg, dry wt.), presumably from lead shot, but none of the other samples had notably elevated metal concentrations. We suggest that scat and digesta be analyzed more widely by biologists and resource managers seeking a simple, inexpensive assessment of contaminants in local wildlife habitat.

Thus, hydrologic alterations such as diking and ditch drainage that reduce salinity and increase peat aeration can cause radical changes in the composition of salt marsh soils. Experimental short-term desalination and drainage of salt marsh cores in greenhouse microcosms caused Spartina production to increase after one growing season, reflecting decreased salt stress and sulfide toxicity. However, production thereafter declined, likely due to pyrite oxidation and acidification in drained treatments and sulfide accumulation in waterlogged treatments. A survey of longer-term (decadal) effects of diking on peat composition of Cape Cod, Massachusetts, USA, marshes revealed acidification, Fe(II) mobilization, and decreased organic content in drained sites. Despite the aerobic decomposition of organic matter, abundant nutrients remained as sorbed NH4 and mineral-bound PO4. In diked, seasonally waterlogged sites, porewater alkalinity, sulfide, ammonium and orthophosphate were much lower, and organic solids higher, than in adjacent natural marsh. Seawater was added to cores from diked marshes to study the effects of tidal restoration. Salination of the drained peat increased porewater pH, alkalinity, ammonium, orthophosphate, Fe, and Al; copious ammonium N, and Fe(II) for sulfide precipitation favored Spartina growth. Salination of diked-waterlogged peat increased sulfate reduction and caused 6-8 cm of sediment subsidence. The resulting increase in porewater sulfides and waterlogging decreased vigor of transplanted Spartina alterniflora. Results indicate that seawater restoration should proceed cautiously to avoid nutrient loading of surface waters in drained sites or sulfide toxicity in diked-waterlogged marshes.

Owing to the lack of direct observations of movements among marine areas, three classes of genetic markers that differed in mode of inheritance were used to evaluate the degree of genetic differentiation among wintering areas within Prince William Sound (PWS) and the Alaska Peninsula and Kodiak Archipelago (APKA). We could not reject the null hypothesis that the wintering aggregations within each region are composed of a single genetically panmictic population. Differences in genotype frequencies among wintering locations within PWS and APKA were low and nonsignificant for all three classes of markers. Furthermore, we saw no evidence for deviations in Hardy-Weinberg equilibrium or gametic disequilibrium between loci within a winter collection site as would be expected if these locales were composed of individuals from reproductively isolated (and genetically distinct) breeding locales. Finally, no evidence for significant structuring was noted between PWS and APKA. Lack of spatial genetic structuring could be due to the cumulative effects of low levels of gene flow over long time periods, low levels of gene flow by immature birds moving between marine habitats, or to episodic dispersal caused by habitat alteration (e.g. volcanic eruptions). Harlequin Ducks are likely to recolonize or enhance populations in areas recovering from environmental damage via emigration of birds from non-affected areas. Demographic studies suggest, however, that levels of movements are low, and that population recovery by emigration is a long-term process.

Pharyngeal swab sampling rarely (>0.1%) detected birds that were exposed to P. multocida in these populations. Geese with serum antibody levels indicating recent infection with P. multocida were found at both breeding colonies. Prevalence of seropositive birds was 3.5% at Wrangel Island, an area that has no recorded history of avian cholera epizootics. Prevalence of seropositive birds was 2.8% at Banks Island in 1994, but increased to 8.2% during 1995 and 1996 when an estimated 40,000-60,000 snow geese were infected. Approximately 50% of the infected birds died during the epizootic and a portion of the surviving birds may have become carriers of the disease. This pattern of prevalence indicated that enzootic levels of infection with P. multocida occurred at both breeding colonies. When no avian cholera epizootics occurred, female snow geese (4.7%) had higher antibody prevalence than males (2.0%).

AN - 17476707; 4677082 AB - Cavity-nesting birds that excavate nest holes may be limited by the availability of suitable substrates for excavation. Suitability of trees for excavation may be influenced by substrate hardness and excavation strength of the bird. Excavation strength, in turn, may vary among bird species, causing nest-tree selection to vary among excavator species. We examined use of quaking aspens (Populus tremuloides) for nest trees as a function of tree hardness in four species of woodpeckers: Williamson's Sapsucker (Sphyrapicus thyroideus), Red-naped Sapsucker (S. nuchalis), Downy Woodpecker (Picoides pubescens), and Hairy Woodpecker (P. villosus). Hardness of trees was measured at 95 nest trees, 94 neighboring trees, and 150 random trees using a new technique described here. Other investigators have speculated that the gross external appearance of trees/snags can be used to estimate hardness. Hardness decreased from live trees to partly dead trees to dead trees and with increasing height in trees, but hardness was not related to other external features such as numbers of conks or percentage of the tree covered with bark. All four bird species chose nest trees that were softer than neighboring or random trees, and nest trees were softer at nests than at other heights measured. The four species selected trees of different hardness for nesting; Red-naped Sapsucker and Hairy Woodpecker chose harder trees than Williamson's Sapsucker and Downy Woodpecker. These results suggest that primary cavity nesters are sensitive to subtle characteristics of trees that reflect hardness, some of which may not be apparent in the external appearance of the trees.

Therefore, we compared patterns of prey selection between wolves and cougars (Puma concolor) to ascertain the effects of multiple predators on prey and on each other. Because of differences in hunting techniques, we predicted that wolves would kill more vulnerable classes of prey than cougars. Our results did not support this prediction. Whitetailed deer (Odocoileus virginianus) composed the greatest proportion of wolf (0.83) and cougar kills (0.87), but elk (Cervus elaphus) and moose (Alces alces) composed a larger proportion of wolf (0.14, 0.03, respectively) than cougar (0.06, 0.02, respectively) kills. Wolves and cougars selected older and younger deer and elk than did hunters. Cougars killed relatively more bull elk (0.74) than did wolves (0.48). Male deer killed by cougars had shorter diastema lengths than did male deer killed by wolves (P = 0.02). Pack hunting by wolves and dense stalking cover may have partially explained the failure to support predictions of the coursing versus stalking dichotomy. Wolves and cougars may be exhibiting exploitation and interference competition that is affecting each others' behavior and dynamics, and that of their prey.

The description of such datasets often requires a large number of parameters, among which certain patterns might be discernible. For example, one may consider a long-term study producing estimates of annual survival rates; of interest is the question whether these rates have declined through time. Several statistical methods exist for examining pattern in collections of parameters. Here, I argue for the superiority of "random effects models" in which parameters are regarded as random variables, with distributions governed by "hyperparameters" describing the patterns of interest. Unfortunately, implementation of random effects models is sometimes difficult. Ultrastructural models, in which the postulated pattern is built into the parameter structure of the original data analysis, are approximations to random effects models. However, this approximation is not completely satisfactory: failure to account for natural variation among parameters can lead to overstatement of the evidence for pattern among parameters. I describe quasi-likelihood methods that can be used to improve the approximation of random effects models by ultrastructural models.

Gravid female L. subangulata were found nine months of the year. On 19 May 1995, a L. subangulata was discovered releasing a superconglutinate, the first record confirming that this species used this specialized reproductive strategy. Superconglutinate release occurred from late May to mid-July in water temperatures ranging from 20.0 to 23.5 C. Laboratory experiments indicated that two fish species served as primary hosts, the spotted bass (Micropterus punctulatus) and largemouth bass (M. salmoides). Secondary host fish included the eastern mosquitofish (Gambusia holbrooki), guppy (Poecilia reticulata) and bluegill (Lepomis macrochirus). The glochidial morphology of L. subangulata was similar to other lampsiline species. Using quantitative survey methods, no evidence of recent juvenile recruitment was found in the largest known extant L. subangulata population.

Most direct saline-induced mortality happens before day 6 of life, after which time the nasal salt glands become functional. At Fish Springs National Wildlife Refuge in western Utah, the water available to Canada goose (Branta canadensis) goslings ranged from brackish to highly saline (3100-25,000+ mu S/cm) throughout the summer and differed spatially across the impoundments; no fresh water was available. We followed collar-marked, radio-marked and unmarked broods from hatching to day 15 to determine early survival of all goslings hatched in 1997. Nineteen broods hatched between 25 April and 25 May. We analyzed the relationship between specific conductivity of water and gosling mortality in 1997. The levels of salinity found at the refuge within 15 d after hatching were independent of mortality. During dry years salinity levels increase earlier in the Spring and may limit gosling productivity.

Analyses of most headspace and blended gas samples from the ice-bonded permafrost portion of the core holes yielded C sub(1)/(C sub(2) + C sub(3)) hydrocarbon gas ratios and CH sub(4)-C isotopic compositions ( delta super(13)C CH sub(4)) indicative of microbially sourced CH sub(4) gas. However, near the base of ice-bonded permafrost and into the underlying non-frozen stratigraphic section, an increase in ethane (C sub(2)) concentrations, decreases in C sub(1)/(C sub(2) + C sub(3)) hydrocarbon gas ratios, and CH sub(4)-C isotopic ( delta super(13)C CH sub(4)) data indicate the presence of hydrocarbon gases derived from a thermogenic source. The thermogenic gas below permafrost in the Mackenzie Delta likely migrated from deeper hydrocarbon accumulations and/or directly from thermally mature hydrocarbon source rocks.

MOAB can create spatially explicit, individual-based animal foraging models. Users can create or replicate heterogeneous landscape patterns, and place resources and individual animals of a given species on that landscape to simultaneously simulate the foraging behavior of multiple species. The heuristic rules for animal behavior are maintained in a user-modifiable expert system. MOAB can be used to explore hypotheses concerning the influence of landscape pattern on animal movement and foraging behavior. A red fox (Vulpes vulpes L.) foraging and nest predation model was created to test MOAB's capabilities. Foxes were simulated for 30-day periods using both expert system and random movement rules. Home range size, territory formation and other measures of movement were compared to data from field studies, the random movement simulations, and other available simulation studies. A striped skunk (Mephitis mephitis L.) model also was developed. The expert system model proved superior to stochastic in respect to territory formation, general movement patterns and home range size.

We assessed postrelease behaviors and survival of three groups of black-footed ferrets, each with different prerelease experience. Eighteen ferret kits less than or equal to 60 days of age were moved with their dams from cages to 80-m super(2) outdoor pens with prairie dog burrows. These animals were compared to animals reared in standard cages (n = 72), some of which were given experience killing prairie dogs (n = 32). Ferrets were released onto white-tailed prairie dog (Cynomys leucurus) colonies in Wyoming, USA, in fall, 1992. Radio-tagged cage-reared ferrets made longer nightly moves and dispersed further from release sites than their pen-reared counterparts. The band return rate was 4-fold higher for pen-reared animals than for cage-reared animals during surveys conducted about 1 month after release. We recommend routine use of quasi-natural outdoor pens for prerelease conditioning of black-footed ferrets.

Average background trace element levels for the basin were determined from the collection and subsequent analyses of bed sediment samples from small rural watersheds and from a prehistoric (5000 BP) site in Paris. Concentrations are relatively low, and similar to those observed for fine-grained bed sediments from unaffected areas in the United States and Canada. However, the concentrations are somewhat higher than the reference levels presently adopted by French water authorities for areas north of the Seine Basin, which have similar bedrock lithologies. Downstream trace element variations were monitored in 1994 and 1995 using fresh surficial floodplain samples that were collected either as dried deposits a few days after peak discharge, or immediately after peak discharge (under less than or equal to 30 cm of water). Chemical comparisons between fresh floodplain deposits, and actual suspended sediments collected during flood events, indicate that, with some caveats, the former can be used as surrogates for the latter. The floodplain sediment chemical data indicate that within the Seine Basin, from the relatively unaffected headwaters through heavily affected urban streams, trace element concentrations vary by as much as three orders of magnitude. These trace element changes appear to be the result of both increases in population as well as concomitant increases in industrial activity.

Nondestructive analysis of whole samples by solid-state NMR permits a direct assessment of the polarity of SOM that is not possible by elemental analysis. The percent of organic carbon associated with polar functional groups was estimated from the combined fraction of carbohydrate and carboxylamide-ester carbons. A plot of the measured partition coefficients (K sub(oc)) of carbon tetrachloride (CT) vs. percent polar organic carbon (POC) shows distinctly different populations of soils and sediments as well as a roughly inverse trend among the soil/sediment populations. Plots of K sub(oc) values for CT against other structural group carbon fractions did not yield distinct populations. The results indicate that the polarity of SOM is a significant factor in accounting for differences in K sub(oc) between the organic matter in soils and sediments. The alternate direct correlation of the sum of aliphatic and aromatic structural carbons with K sub(oc) illustrates the influence of nonpolar hydrocarbon on solute partition interaction. Additional elemental analysis data of selected samples further substantiate the effect of the organic matter polarity on the partition efficiency of nonpolar solutes. The separation between soil and sediment samples based on percent POC reflects definite differences of the properties of soil and sediment organic matters that are attributable to diagenesis.

However, analysis of the California Statewide Fire History Database shows that, since 1910, fire frequency and area burned have not declined, and fire size has not increased. Fire rotation intervals have declined, and fire season has not changed, implying that fire intensity has not increased. Fire frequency and population density were correlated, and it is suggested that fire suppression plays a critical role in offsetting potential impacts of increased ignitions. Large fires were not dependent on old age classes of fuels, and it is thus unlikely that age class manipulation of fuels can prevent large fires. Expansion of the urban-wildland interface is a key factor in wildland fire destruction. JF - Science (Washington) AU - Keeley, JE AU - Fotheringham, C J AU - Morais, M AD - US Geol. Surv. Biol.

Scant information exists on the extent of the decline, as this bay was not investigated for water quality concerns before the die-offs and limited areas were sampled after the primary die-off. We use imagery from the Advanced Very High Resolution Radiometer (AVHRR) to examine water clarity in Florida Bay for the period 1985 to 1997. The AVHRR provides data on nominal water reflectance and estimated light attenuation, which are used here to describe turbidity conditions in the bay on a seasonal basis. In situ observations on changes in seagrass abundance within the bay, combined with the satellite data, provide additional insights into losses of seagrass. The imagery shows an extensive region to the west of Florida Bay having increased reflectance and light attenuation in both winter and summer begining in winter of 1988. These increases are consistent with a change from dense seagrass to sparse or negligible cover. Approximately 200 km super(2) of these offshore seagrasses may have been lost during the primary die-off (1988 through 1991), significantly more than in the bay. The imagery shows the distribution and timing of increased turbidity that followed the die-offs in the northwestern regions of the bay, exemplified in Rankin Lake and Johnson Key Basin, and indicates that about 200 km super(2) of dense seagrass may have been lost or severely degraded within the bay from the start of the die-off. The decline in water clarity has continued in the northwestern bay since 1991. The area west of the Everglades National Park boundaries has shown decreases in both winter turbidity and summer reflectances, suggestive of partial seagrass recovery. Areas of low reflectance associated with a majorSyringodium filiforme seagrass meadow north of Marathon (Vaca Key, in the Florida Keys) appear to have expanded westward toward Big Pine Key, indicating changes in the bottom cover from before the die-off. The southern and eastern sections of the Bay have not shown significant changes in water clarity or bottom albedo throughout the entire time period.

Agency meetings, media reports and editorials, legal briefs, and regulatory hearings have been forums for contentious debate. The management challenge is extremely complex and until recently has defied solution. The core problem is that aerial tourism occurs at the regulatory interface of two major government agencies that have very different mandated missions--the Federal Aviation Administration and the National Park Service. These agencies creatively employed a federal advisory body known as the National Parks Overflights Working Group to recommend a way to regulate commercial, park-dependent air tourism. Comprising aviation interests, environmental interests, and a Native American representative, the Working Group carefully crafted a solution that blended the authorities and responsibilities of the two agencies into a regulatory mechanism that has been deemed workable and acceptable to all parties. The Federal Aviation Administration, in cooperation with the National Park Service, is now converting this compromise process into a proposed Federal Aviation Regulation, even as the U.S. Congress is on the verge of converting it into law. If successfully implemented by the two federal agencies, this approach may provide a solution to air tourism management problems.

From 1990-1993, the opportunity was presented to resurvey six of these lakes to determine inter-annual change within the set of characteristics surveyed in 1988. If changes were evident, a second objective was to provide guidance to park management about the value of a long-term lake monitoring program. Secchi-disk clarity, water temperature, and pH of the lakes in 1988 were within the range of values obtained between 1990 and 1993. Conductivities and concentration of nutrients in some lakes were not consistent in 1990-1993 with the values recorded in 1988. Although the dominant phytoplankton taxa in the lakes varied among years, the taxa in individual lakes were in consistent among years, with the exception of two lakes. Rotifer assemblages were consistent among years, but most of the lakes exhibited dramatic changes in some years, as did crustacean zooplankton assemblages. Suggestions were made about the need for a long-term monitoring program to evaluate the status and trends of park lakes.

Analysis of benthic foraminifers and molluscs from modern monitoring sites within Florida Bay allows us to determine what environmental parameters control spatial and temporal variability of their assemblages. Faunal assemblages associated with specific environmental parameters, including salinity and substrate, serve as proxies for an interpretation of paleoecologic data. The faunal record preserved in two shallow (< 2 m) cores in central Florida Bay (Russell Bank and Bob Allen Bank) provides a record of historical trends in environmental parameters for those sites. Analysis of these two cores has revealed two distinct patterns of salinity change at these sites: 1) a long-term trend of slightly increasing average salinity; and 2) a relatively rapid change to salinity fluctuations of greater frequency and amplitude, beginning around the turn of the century and becoming most pronounced after 1940. The degree of variability in substrate types at each locality limits interpretations of substrate trends to specific sites. A common sequence of change is present in the Russell Bank and Bob Allen Bank cores: from mixed grass and bare-sediment indicators at the bottom of the cores, to bare-sediment dwellers in the center, to a dominance of vegetative-cover indicators at the top of the cores. Changes in interpreted salinity patterns around the turn of the century are consistent with the timing of the construction of the Flagler Railroad from 1905 to 1912, and the Tamiami Trail and the canal and levee systems between 1915 and 1928. Beginning around 1940, the changes in the frequency and amplitude of salinity fluctuations may be related to changes in water management practices, meteorologic events (frequent hurricanes coupled with severe droughts in 1943 and 1944), or a combination of factors. The correspondence of these changes in Florida Bay with changes in the terrestrial Everglades suggests factors affecting the entire ecosystem are responsible for the salinity and substrate patterns seen in Florida Bay.

This study followed a prior study that monitored RS in the same hatcheries from 1988 through 1992. In the current study, we found that the prevalence of RS-positive fish declined at two hatcheries relative to the preceding 5 years. Prevalence dropped from near 90% in 1992 to below 50% at both sites by 1993 and was less than 20% at three locations in 1995. In contrast, prevalence increased at four of seven sites in 1993 and six of seven sites in 1994. This indicated that previously reported declines in RS prevalence at these locations might have been temporary. Our results showed that in 1993 the majority of fish at all monitored hatcheries had low RS-antigen levels and remained that way at most locations through 1996. These results suggest that certain hatchery practices may limit the severity of RS infections. Although elevations at two sites in 1994 and 1995 indicate reductions in RS were temporary in the short term, long-term monitoring will undoubtedly be required given the many factors that influence disease processes.

Values of delta super(18)O are directly influenced by temperature and evaporation and may be related to salinity. delta super(13)C values of delta super(13)C are sensitive to organic and inorganic sources of carbon and are influenced by productivity. Analyses of eight mollusk species from five short-core localities across Florida Bay show large ranges in the values of delta super(13)C and delta super(18)O, and reflect the variation of the bay over decades. Samples from southwestern Florida Bay have distinct delta super(13)C values relative to samples collected in northeastern Florida Bay, and intermediate localities have intermediate values. super(13)C values of delta super(13)C grade from marine in the southwest bay to more estuarine in the northeast. Long cores (> 1 m) with excellent chronologies were analyzed from central and eastern Florida Bay. Preliminary analyses of Brachiodontes exustus and Transenella spp. from the cores showed that both delta super(13)C and delta super(18)O changed during the first part of the twentieth century. After a century of relative stability during the 1800s, delta super(13)C decreased between about 1910 and 1940, then stabilized at these new values for the next five decades. The magnitude of the reduction in delta super(13)C values increased toward the northeast. Using a carbon budget model, reduced delta super(13)C values are interpreted as resulting from decreased circulation in the bay, probably associated with decreased freshwater flow into the Bay. Mollusk shell delta super(18)O values display several negative excursions during the 1800s, suggesting that the bay was less evaporitic than during the twentieth century. The isotope records indicate a fundamental change took place in Florida Bay circulation early in the twentieth century. The timing of the change links it to railroad building and early drainage efforts in South Florida rather than to flood control and water management measures initiated after World War II.

We exposed fish with an established infection of Rs to 120% total dissolved gas (TDG) for 96 h and monitored severity of GBT signs in the fins and gills, Rs infection level in kidneys by using an enzyme-linked immunosorbent assay (ELISA), and mortality. Mortality occurred rapidly after exposure to 120% TDG, with a LT20 (time necessary to kill 20% of the population) of about 37 h, which is at a minimum about 16% earlier than other bioassays we have conducted using fish that had no apparent signs of disease. Fish that died early (from 31 to 36 h and from 49 to 52 h) had significantly higher infection levels (mean plus or minus SE ELISA absorbance = 1.532 plus or minus 0.108) than fish that survived for 96 h (mean plus or minus SE ELISA absorbance = 0.828 plus or minus 0.137). Fish that died early also had a significantly greater number of gill filaments occluded with bubbles than those that survived 96 h. Conversely, fish that survived for 96 h had a significantly higher median fin severity ranking than those that died early. Our results indicate that fish with moderate to high levels of Rs infection are more vulnerable to the effects of dissolved gas supersaturation (DGS) and die sooner than fish with lower levels of Rs infection. However, there is a substantial amount of individual variation in susceptibility to the apparent cumulative effects of DGS and Rs infection. Collectively, our findings have important implications to programs designed to monitor the prevalence and severity of GBT in juvenile salmonids in areas like the Columbia River basin, and perhaps elsewhere.

Pulses of diluted Holstein calf feces containing oocysts were passed through saturated columns packed with either glass beads, coarse sand, or shale aggregate. Effluent chloride breakthrough curves (BTCs) were used to fit pore water velocities and dispersions for each column to the CDE. These pore water velocities were then used to fit dispersion, retardation and first-order decay factors to the CDE for C. parvum oocyst BTCs for each column. Dispersion coefficients for oocysts averaged 0.8 cm super(2) s super(-1) in glass beads, 1.7 cm super(2) s super(-1) in sand, and 1.3 cm super(2) s super(-1) in shale aggregate. The ratio of oocyst dispersion to chloride dispersion was <1 for all substrates, suggesting oocysts experienced less shear and turbulence than the pore water. Diffusivities of 0.07 cm for glass beads, 0.15 cm for sand, and 0.09 cm for shale aggregate show that facilitated transport in sand was greater than in the other two substrates. Retardation coefficients for oocysts averaged 1.0 in glass beads and sand and 0.9 in shale aggregate, indicating oocysts did not adhere to these substrates. First-order decay coefficients of 0.5 s super(-1) for glass beads, 0.8 s super(-1) for sand, and 0.6 s super(-1) for shale aggregate indicate significantly higher removal rates in the sand columns. These data suggest oocysts may travel significant distances in both subsurface and overland flow.

Theoretical relations are derived for the flow between an injector and producer, including the dependence of permeability on effective stress. Four relations for permeability as a function of effective stress are used to match field data for the hot dry rock systems at Rosemanowes, Cornwall, and Fenton Hill, New Mexico. The flow and water loss behavior of these systems are well explained by the influence of effective stress on permeability. All four relations for permeability as a function of effective stress are successful in matching the field data, but some have difficulty in determining unique values for elastic and hydrologic parameters.

The ground cracks and distributed deformation damaged both pipelines and surface structures. To evaluate the mechanism of soil failure, detailed subsurface investigations were conducted at four sites. Three sites are underlain by saturated sandy silts with low standard penetration test and cone penetration test values. These soils are similar to those that liquefied during the 1971 San Fernando earthquake, and are shown by widely used empirical relationships to be susceptible to liquefaction. The remaining site is underlain by saturated clay whose undrained shear strength is approximately half the value of the earthquake-induced shear stress at this location. This study demonstrates that the heterogeneous nature of alluvial fan sediments in combination with variations in the ground-water table can be responsible for complex patterns of permanent ground deformation. It may also help to explain some of the spatial variability of strong ground motion observed during the 1994 earthquake.

In this work, methods for characterizing a wetland's hydrology from hydrographs were developed, and the importance of ground water to the physical and geochemical conditions in the root zone was investigated. Detailed sampling of nearly continuous hydrographs showed that sites with greater ground-water discharge had higher water tables and more stable hydrographs. Subsampling of the continuous hydrograph failed to characterize the sites correctly, even though the wetland complex is located in a strong regional ground-water-discharge area. By comparing soil-moisture-potential measurements to the water-table hydrograph at one site, we noted that the amount of root-zone saturation was not necessarily driven by the water-table hydrograph but can be a result of other soil parameters (i.e., soil texture and associated capillary fringe). Ground-water discharge was not a significant determinant of maximum or average temperatures in the root zone. High ground-water discharge was associated with earliest date of thaw and shortest period of time that the root zone was frozen, however. Finally, the direction and magnitude of shallow ground-water flow was found to affect the migration and importance of a geochemical species. Areas of higher ground-water discharge had less downward penetration of CO sub(2) generated in the root zone. In contrast, biotically derived CO sub(2) was able to penetrate the deeper ground-water system in areas of ground-water recharge. Although ground-water flows are difficult to characterize, understanding these components is critical to the success of wetland restoration and creation efforts.

Up to 73% of [U- super(14)C]-MTBE and 84% of [U- super(14)C]-TBA were degraded to super(14)CO sub(2) under mixed aerobic/anaerobic conditions. No significant mineralization was observed under strictly anaerobic conditions. The results indicate that, under the mixed aerobic/anaerobic conditions characteristic of stream-bed sediments, microbial processes may provide a significant environmental sink for MTBE and TBA delivered to surface water bodies by contaminated groundwater or by other sources.

In this paper, we use data from grazed and ungrazed coastal meadows in Finland to evaluate and extend this general conceptual model of the factors controlling species density. Structural equation analysis was used to evaluate a model for all meadows and then to perform a multigroup analysis to determine how grazed and ungrazed meadows differ. By itself, biomass could explain only 12% of the variation in species density while the multivariate model was able to explain 47% using five types of predictor variables: site, soil, flooding, grazing, and biomass. Analyses found that flooding explained the greatest amount of variability in species density, primarily through negative effects on the species pool. Grazing was also found to have a strong effect on species density and results suggest that its negative influence may be largely through reductions in the species pool in grazed meadows. The most important difference found between grazed and ungrazed meadows was that species density had a strong negative relationship to biomass in the ungrazed meadows but no significant relationship in the grazed ones. Thus, it appears that the influence of competition on species density was much greater in ungrazed meadows compared to grazed ones.

Most of the islands beaches were searched on an irregular schedule, resulting in the recovery of 876 King Eider carcasses. A sub-sample of beaches were intensively studied to estimate daily persistence rate and detection probability. Using these data, our model predicted that an additional 733 plus or minus 70 King Eider carcasses were not detected during our searches. Therefore, we estimate that at least 1609 plus or minus 70 King Eider carcasses occurred on beaches as a result of the spill. We lacked sufficient sample size to model losses for other species, thus we applied the estimated recovery rate for King Eiders (54%) to other species and estimate a total combined loss of 1765 birds. In addition, 165 birds were captured alive making the total estimated number of birds impacted by the M/V Citrus spill 1930. Given that oiled birds occurred in places on the island which could not be systematically searched combined with the fact that it was unlikely that oiled birds that died at sea would have been recovered during our searches, our estimate of total mortality associated with the spill should be considered a minimum.

The view some Americans have of indigenous people and protected areas is not compatible with third world realities. Since the problems and challenges of protecting areas in northern and southern countries are alike in many ways, however, a Eurocentric seeking to articulate the special circumstances faced by tropical countries offers these suggestions.

A natural system for delineation and codification of basins is presented which is based upon topographic control and the topology of the river network. These characteristics make the system well suited for implementation and use with digital elevation models (DEMs) and geographic information systems. A demonstration of these traits is made with the 30-arcsecond GTOPO30 DEM for North America. The system has additional appeal owing to its economy of digits and the topological information that they carry. This is illustrated through presentation of comparisons with USGS hydrologic unit codes and demonstration of the use of code numbers to reveal dependence or independence of water use activities within a basin.

Development of the Council, however, began over four years ago and included two major events, the 1996 and 1998 Texas Water Monitoring Congresses. These meetings, in many ways, define the development, status and future directions of Council, as it exists today. This paper describes the development of the Texas Water Monitoring Council to the present and discusses some challenges for its future. Efforts to address the issues encompassed within the scope of "water monitoring" in Texas began in 1995 when several federal and state agencies held informal discussions on ways to work more efficiently together to improve the status of data collection and the usefulness of water information. The forces driving these discussions were the increasing cost of collecting water data in the face of flat or declining funding and the often disparate efforts of many agencies to collect similar, if not redundant, data - data, which in turn, was limited in its availability to external entities. These discussions quickly focused on developing a mechanism to facilitate and build consensus on approaches and responses to water data needs for Texas. The result was formation of an ad hoc group of representatives from federal, state, and regional water resource agencies to plan the Texas Water Monitoring Congress, which convened in Austin in September 1996.

Bright plumage in males is commonly thought to arise as a result of sexual selection by females such that males with bright coloration possess high fitness. However, bright plumage potentially could expose males to increased predation risk. Consistent with this idea, males of many highly dichromatic passerine species do not incubate. I tested whether brightly-colored males avoid incubation to reduce the probability of visual predators locating their nest. This hypothesis predicts greater hatching success for clutches incubated by cryptically-colored individuals than by brightly-colored individuals. The Northern Cardinal (Cardinalis cardinalis) is a common dichromatic species that breeds throughout the eastern U.S. I placed two button-quail (Turnix sp.) eggs in each of 203 simulated cardinal nests. Dull brown cardboard, simulating a female cardinal, was placed over about half of all clutches. Bright red cardboard, simulating a male cardinal, was placed over the other clutches. Nest success was highest for well-concealed nests (87%) and lowest for nests in open habitat (54%). Nests containing red cardboard did not have significantly lower success than nests with brown cardboard, nor did I detect a significant color x vegetation-density interaction. My analysis may have had insufficient power to detect an effect of color on nest success; alternatively, brightly-colored males that do not incubate may achieve benefits unrelated to predation risk.

Bloaters remained on or near bottom during the day. At night, bloaters were distributed throughout 30-65 m of water, depending on bottom depth. Shallowest depths of migration were not related to water temperature or incident light. Maximum distances of migration increased with increasing bottom depth. Nighttime midwater densities ranged from 0.00 to 6.61 fish/1,000 m super(3) and decreased with increasing bottom depth. Comparisons of length distributions showed that migrating and nonmigrating bloaters did not differ in size. However, at most sites, daytime bottom catches collected a greater proportion of larger individuals compared with nighttime midwater or bottom catches. Mean target strengths by 5-m strata indicated that migrating bloaters did not stratify by size in the water column at night. Overall, patterns in frequency of empty stomachs and mean digestive state of prey indicated that a portion of the bloater population fed in the water column at night. Bloater diet composition indicated both midwater feeding and bottom feeding. In sum, although a portion of the bloater population fed in the water column at night, bloaters were not limited to feeding at this time. This research confirmed that bloaters are opportunistic feeders and did not fully support the previously proposed hypothesis that bloater vertical migration is driven by the vertically migrating macroinvertebrate the opossom shrimp Mysis relicta..

Field estimates of daily ration for age-1-4 fish during May through October 1987 and 1988 were compared with independent predictions made by the Wisconsin energetic model and an energetic model developed by Karas and Thoresson. Predictions of daily ration using the Wisconsin model were lower than daily rations estimated from field data for all ages, primarily due to poor model-field agreement at temperatures above 22 degree C. This caused estimates of cumulative consumption from the Wisconsin model to be 25-50% lower than field estimates. Predictions of daily ration by the Karas-Thoresson model agreed with field estimates over a temperature range of 10-26 degree C for age-1-3 yellow perch but not for older fish. Despite improvement, model predictions of cumulative consumption were 2-35% lower than field estimates. Although these tests of predicted and estimated rations may provide insight into which model produced more accurate results, it must be emphasized that field measures of daily ration are also estimates and may be in error, particularly at temperatures above 22 degree C where gastric evacuation rates were estimated. The Karas-Thoresson modification of the Wisconsin energetic model produced better fits to field ration data and is recommended for model applications.

These differences have been attributed to both variations in stream inputs and in situ lake processes (Priscu, 1995; Lizotte et al., 1996, Spigel and Priscu, 1996). This study examines the role of nitrifying bacteria in nitrogen transformations in these lakes. Applying two polymerase chain reaction (PCR) assays targeting the 16S rRNA genes of ammonia-oxidizing bacteria and the active site of the ammonia monooxygenase gene (amoA), the distribution of ammonia-oxidizers was examined in six Antarctic lakes: Lake Bonney, Lake Hoare, Lake Fryxell and Lake Joyce in the Taylor Valley, Lake Miers in the the Miers Valley and Lake Vanda in the Wright Valley. Using a two stage amplification procedure, ammonia-oxidizers from both the beta and gamma- subclasses of the Proteobacteria were detected and their relative abundances were determined in samples collected from all sites. Ammonia-oxidizers were detected in all lakes sampled. Members of the gamma subclass were only present in the saline lakes. In general, nitrifiers were most abundant at depths above the pycnocline and were usually associated with lower concentrations of NH sub(4) and elevated concentrations of NO sub(3) or NO sub(2). The distribution of nitrifiers suggests that the primary N sub(2)O peak observed in most of the lakes was produced via nitrification. Preliminary data on the rate of nitrification (Priscu et al., 1996) support the occurrence of nitrification and the presence of nitrifiers at the depth intervals where nitrifiers were detected. In all lakes, except Lake Miers, the data indicate that nitrifying bacteria have an important role in the vertical distribution of nitrogen compounds in these systems.

Because of the spring action of the furcula during the wingbeat, small changes in the mechanical properties of this bone may have measurable impacts on long-distance flight. We examined the furculae and ingesta of free-ranging American coots (Fulica americana) in San Francisco Bay (California, USA), where they consume a diet high in Al. We measured the spring stiffness and phase angle ( delta ) of the furculae and the concentrations of Al, Ca, F, Mg, and P in both the furculae and ingesta. The ingesta had mean Al concentrations (2,384 mu g/g, dry weight) and Al:P molar ratios (6.4:1) predicted to affect bone integrity but the bone concentrations of Al were near the normal range and the furcula stiffness did not change with Al concentration. The tan delta of the furculae changed with Al concentration but the relationship was weak. The chemical speciation of the ingested Al may have affected its physiologic role and the high mean levels of ingested calcium (71,283 mu g/g, dry weight) very likely neutralized the activity of the Al. Controlled feeding studies have shown that F strengthens avian bones. The bones in our study had molar concentrations of F more than two orders of magnitude greater than Al (170:1) but F appears to have insignificant influence on bone mechanics. The coots in San Francisco Bay apparently are not suffering furcula impairment despite a diet high in Al.

Incubating adult females captured in late May through mid-June 1997 had significantly higher concentrations of selenium in their blood (mean = 5.60 ppm) than adult females captured during wing molt in late July 1996 (mean = 2.78 ppm). Females that nested early or were in good body condition had higher concentrations of selenium in their blood than did other nesting females. Blood samples from 4 of 29 goslings had detectable levels of selenium (mean = 0.14 ppm). Our findings suggest that emperor geese are exposed to more selenium in the marine environment of their wintering and staging areas on the Alaska Peninsula than on the breeding grounds. The highest concentration of mercury found in the blood of emperor geese was 0.24 ppm. One bird had a blood lead concentration of 0.67 ppm, but 82% had no detectable lead in their blood, suggesting that lead exposure from the ingestion of lead shot poses little threat for emperor geese in western Alaska, contrary to findings reported for sympatric spectacled eiders (Somateria fischeri).

The number of females per male varied from zero to three. Several male and territory traits were significantly correlated with number of females per male. We used multiple regression to obtain a single measure of male quality and a single measure of territory quality. These measures of male and territory quality correlated with each other and with male pairing success. We used path analysis to separate direct effects of male quality on pairing success from indirect effects due to high-quality males obtaining high-quality territories. Both direct and indirect pathways had significant effects on pairing success, and direct and indirect effects of male traits on pairing success were about equal. This study illustrates an analytical approach for estimating the relative importance of direct and indirect causal relationships in natural systems.

The U.S. Minerals Management Service (MMS) is mandated to manage the development of that country's OCS oil and gas resources, while also ensuring safe operations and protecting the human and natural environment. The level of Gulf of Mexico OCS deepwater activities, both drilling and production, has steadily increased, and the discoveries in the deepwater tracts have begun to stack up. Very high rates of production by prolific deepwater wells have convinced operators that the deepwater Gulf of Mexico is a sound investment, and the trend continues to show signs of increase.

Central to the Plan is a set of ambitious continental population goals and habitat objectives to be met through broad-based public-private partnerships. Inadequate attention has been paid to evaluation of the Plan, despite the fact that Plan delivery can be enhanced via improved understanding of the effects of habitat conservation on waterfowl population dynamics. Several factors confound the effort to evaluate the Plan at regional and continental levels, including difficulties in accounting for national land-use policies. To date, evaluation has proceeded along 2 avenues of investigation: (1) the study of conservation actions at local-regional levels, and (2) statistical assessment of Plan assumptions. Among other things, results thus far indicate duck production from the U.S. Northern Great Plains has increased in recent years, and intensive treatments such as planted cover have had positive effects on local reproductive success. Many duck species currently exceed Plan population goals; however, population levels of some species, most notably northern pintail (Anas acuta), remain below expectations based on historic relationships with precipitation. Management implications include the need for ongoing and more carefully prioritized conservation efforts, broader partnerships, and improved understanding of the linkages between habitats and biological processes. Delivery of the Plan must involve collaboration among the Continental Evaluation Team, joint venture partners, the Adaptive Management and Assessment Team of the U.S. Fish and Wildlife Service, and other conservation groups. Although the challenges and projected costs of Plan conservation efforts are considerable, the long-term potential benefits to waterfowl conservation are great.

We compared movements and habitat use of radiomarked female wood ducks with broods in South Dakota on 2 rivers with contrasting prairie landscapes. The perennial Big Sioux River had a broad floodplain and riparian forest, whereas the intermittent Maple River had emergent vegetation along the river channel. Movements between nest sites and brood-rearing areas were longer on the Maple River than on the Big Sioux River (P = 0.02) and were among the longest reported for wood duck broods. Movements on the Big Sioux River were longer in 1992 (P = 0.01), when the floodplain was dry, than in 1993 or 1994. Before flooding occurred on the Big Sioux River, broods used semipermanent wetlands and tributaries outside the floodplain; thereafter, females selected forested wetlands along the river. Broods on the Maple River used emergent vegetation along the river channel throughout the study. Because median length of travel to brood-rearing areas was 2-3 km, we recommend maintenance of brood-rearing habitat every 3-5 km along prairie rivers. Wildlife managers should encourage landowners to retain riparian vegetation along perennial rivers and emergent vegetation along intermittent streams to provide brood-rearing habitat during wet and dry cycles.

We compared recent estimates (1986-95) of tern numbers to objectives identified in the Recovery Plan, used linear regression to estimate trends for local areas (e.g., river segment, reservoir), and route regression to estimate trends for larger segments of the breeding range. We also compared observed estimates of fledging success to the minimum value (0.51 fledglings/pair) thought necessary for population maintenance to determine whether observed productivity could support recent population trends. Although the interior population exceeded the recovery goal of 7,000 birds in 1995, this was due to large increases in tern numbers along a 901-km stretch of the Lower Mississippi River, and numbers for most breeding areas have not reached recovery levels. Trend ( lambda ) was significant for 7 (5 positive, 2 negative) of 31 local areas for which trend could be calculated. At larger scales, lambda was not discernibly different from 1 for the Platte and Missouri river drainages, but lambda was >1 for the Lower Mississippi River drainage. Overall trend for the interior population was 1.090 (95% CI = 1.056-1.111), and 1.024 (95% CI = 0.998-1.045) when data from the Lower Mississippi River were excluded. Fledging success ranged from 0.00 to 2.33 fledglings/pair, and was <0.51 in 9 areas. Based on available fledging success estimates, there is no evidence that productivity within the interior range caused recent increases in tern numbers. Improved rangewide monitoring of numbers and productivity, and information on movements and postfledging survival, are needed to assess recovery criteria and management options for this population of least terns.

Over 90% of the lead-poisoned tundra swans in this area that were necropsied have no ingested lead shot. Spent lead shot from hunting activities over the years is therefore a minor source of lead in these swans. The migrating swans accumulated lethal burdens of lead from ingestion of sediments and aquatic vegetation during a short stopover in the spring. The lead originated from mining and smelting activities. Lead concentrations and physiological characteristics of blood were compared in swans captured in swim-in traps, with moribund swans caught by hand in the lead-contaminated area in 1987 and 1994-1995 and with birds captured by night-lighting in reference areas in 1994-1995. Blood lead concentrations in swans were highest in moribund birds (3.3 mu g g super(-1) in 1987 and 1995), intermediate in those trapped in the contaminated area (0.82 mu g g super(-1) in 1987 and 1.8 mu g g super(-1) in 1995), and lowest (0.11 mu g g super(-1)) in those trapped in the reference areas. delta -aminolevulinic acid dehydratase (ALAD) was significantly inhibited in swans from the contaminated area. Hematocrit and hemoglobin were significantly depressed only in moribund swans. Of the 19 swans found moribund and euthanized, 18 were classified as having lead toxicosis on the basis of lead levels in blood (1.3 to 9.6 mu g g super(-1)) and livers (6 to 40 mu g g super(-1)) and necropsy findings. The 19th swan had aspergillosis. There was no evidence that effects of lead on tundra swans had diminished from 1987 to 1995.

Total mercury, methylmercury, and inorganic mercury were determined in eggs and carcasses (less eggs) from three seepage lakes with a pH range of 6.1-7.0 and a fourth lake in which pH was experimentally increased from 5.5 to 6.8 by addition of alkaline groundwater. The concentration of total mercury in eggs was strongly correlated with that in the maternal carcass. Concentrations and burdens of mercury in eggs and carcasses were inversely correlated with lake water pH, acid-neutralizing capacity, calcium, and dissolved organic carbon. In eggs containing more than 30 ng/g dry weight (4.5 ng/g wet weight) of total mercury, methylmercury averaged 91% of total mercury and ranged from 85% to 96%. Mean burdens of total mercury in individual eggs varied greatly among lakes (range, 2.3-63 pg), and the egg mass averaged 1.9% of the whole-body burden. We conclude that exposure of the developing yellow perch embryo to methylmercury is strongly affected by maternal bioaccumulation, which can vary substantially among and within lakes; however, the toxicological significance of the observed exposure of embryos to methylmercury is unclear.

Samples were collected from the Mississippi River at Baton Rouge, LA from 1991 to 1997 and from sites on the upper Mississippi, the Missouri, and the Ohio Rivers from 1996 to 1997. Atrazine, metolachlor, and alachlor ESA (an alachlor metabolite) were the most frequently detected herbicides in the Mississippi River at Baton Rouge, and, in general, were present in the largest concentrations. The peak annual herbicide load was in 1993 when about 640 metric tons of atrazine, 320 metric tons of cyanazine, 215 metric tons of metolachlor, 53 metric tons of simazine, and 50 metric tons of alachlor were discharged to the Gulf of Mexico. The annual load of atrazine and cyanazine was generally 1-3% of the amount annually applied in the Mississippi River drainage basin; the annual load of acetochlor, alachlor, and metolachlor was generally less than 1%. During 1996-1997 the Ohio River contributed about 50% of the discharge and 50% or more of the herbicide load to the Gulf of Mexico.

ER - TY - JOUR T1 - Movement Patterns and Population Characteristics of the Karner Blue Butterfly (Lycaeides melissa samuelis) at Indiana Dunes National Lakeshore AN - 17247185; 4524676 AB - We conducted a three-year mark-release-recapture study of the endangered Karner blue butterfly (Lycaeides melissa samuelis Nabokov) at Indiana Dunes National Lakeshore to describe the butterfly's movement patterns and to assess seasonal changes in the Karner blue's population structure. Estimated mean Karner blue adult life span was less than 3.5 days. Populations exhibited protandry and about a 2:1 male:female sex ratio at population peak within a brood. Ranges, or maximum distances moved by individual butterflies, were typically less than 100 m. Maximum ranges were less than 1 km. These distances are similar to those reported for other lycaenid butterflies and from other studies of the Karner blue in the midwestern United States. At two sites, fewer than 2% of adults had ranges greater than 300 m, while at a third site 4.3% of adults had ranges greater than 300 m. Given typical subpopulation sizes these movement percentages suggest that few adults per generation will move between subpopulations separated by more than 300 m. Movement of individuals between subpopulation sites is important for maintaining genetic diversity within a metapopulation and for recolonizing areas following local extinctions. Therefore, prudent conservation planning should aim for a landscape with habitat patches suitable for Karner blue butterfly occupancy separated by less than 300 m.

A federal-state collaborative study found that diazinon accounted for most of the observed toxicity of San Joaquin River water in February 1993. Previous studies focused mainly on west-side inputs to the San Joaquin River. In this 1994 study, the three major east-side tributaries to the San Joaquin River - the Merced, Tuolumne, and Stanislaus rivers - and a downstream site on the San Joaquin River were sampled throughout the hydrographs of a late January and an early February storm. In both storms, the Tuolumne River had the highest concentrations of diazinon and transported the largest load of the three tributaries. The Stanislaus River was a small source in both storms. On the basis of previous storm sampling and estimated travel times, ephemeral west-side creeks probably were the main diazinon source early in the storms, whereas the Tuolumne and Merced Rivers and east-side drainages directly to the San Joaquin River were the main sources later. Although 74 percent of diazinon transport in the San Joaquin River during 1991-1993 occurred in January and February, transport during each of the two 1994 storms was only 0.05 percent of the amount applied during preceding dry periods. Nevertheless, some of the diazinon concentrations in the San Joaquin River during the January storm exceeded 0.35 mu g/L, a concentration shown to be acutely toxic to water fleas. On the basis of this study and previous studies, diazinon concentrations and streamflow are highly variable during January and February storms, and frequent sampling is required to evaluate transport in the San Joaquin River Basin.

AN - 69663847; 10097052 AB - For almost 30 years. serious interest has been directed toward natural gas hydrate, a crystalline solid composed of water and methane, as a potential (i) energy resource, (ii) factor in global climate change, and (iii) submarine geohazard. Although each of these issues can affect human welfare, only (iii) is considered to be of immediate importance. Assessments of gas hydrate as an energy resource have often been overly optimistic, based in part on its very high methane content and on its worldwide occurrence in continental margins. Although these attributes are attractive, geologic settings, reservoir properties, and phase-equilibria considerations diminish the energy resource potential of natural gas hydrate. The possible role of gas hydrate in global climate change has been often overstated. Although methane is a "greenhouse" gas in the atmosphere, much methane from dissociated gas hydrate may never reach the atmosphere, but rather may be converted to carbon dioxide and sequestered by the hydrosphere/biosphere before reaching the atmosphere. Thus, methane from gas hydrate may have little opportunity to affect global climate change. However, submarine geohazards (such as sediment instabilities and slope failures on local and regional scales, leading to debris flows, slumps, slides, and possible tsunamis) caused by gas-hydrate dissociation are of immediate and increasing importance as humankind moves to exploit seabed resources in ever-deepening waters of coastal oceans. The vulnerability of gas hydrate to temperature and sea level changes enhances the instability of deep-water oceanic sediments, and thus human activities and installations in this setting can be affected.

AN - 69662536; 10097053 AB - Domestic coal combustion has had profound adverse effects on the health of millions of people worldwide. In China alone several hundred million people commonly burn raw coal in unvented stoves that permeate their homes with high levels of toxic metals and organic compounds. At least 3,000 people in Guizhou Province in southwest China are suffering from severe arsenic poisoning. The primary source of the arsenic appears to be consumption of chili peppers dried over fires fueled with high-arsenic coal. Coal samples in the region were found to contain up to 35,000 ppm arsenic. Chili peppers dried over high-arsenic coal fires adsorb 500 ppm arsenic on average. More than 10 million people in Guizhou Province and surrounding areas suffer from dental and skeletal fluorosis. The excess fluorine is caused by eating corn dried over burning briquettes made from high-fluorine coals and high-fluorine clay binders. Polycyclic aromatic hydrocarbons formed during coal combustion are believed to cause or contribute to the high incidence of esophageal and lung cancers in parts of China. Domestic coal combustion also has caused selenium poisoning and possibly mercury poisoning. Better knowledge of coal quality parameters may help to reduce some of these health problems. For example, information on concentrations and distributions of potentially toxic elements in coal may help delineate areas of a coal deposit to be avoided. Information on the modes of occurrence of these elements and the textural relations of the minerals and macerals in coal may help predict the behavior of the potentially toxic components during coal combustion.

AN - 69646575; 10090814 AB - Rainbow trout (Oncorhynchus mykiss) were exposed to sublethal concentrations of copper (Cu, 14 microgram/liter) and zinc (Zn, 57 and 81 microgram/liter) for a 21-day period. The four treatments included a control, a Cu control, a Cu and low-Zn treatment and a Cu and high-Zn treatment. Selected parameters [e.g., hemoglobin (Hb), hematocrit (Hct), plasma glucose, lactate and cortisol, differential leukocyte count, respiratory burst, tissue metal concentrations, hepatic metallothionein (MT), brain acetylcholinesterase (AChE)] were evaluated at 2, 7, 14, and 21 days of exposure. Whole blood and plasma parameters were not altered by exposure to metals. The percentage of lymphocytes was consistently decreased in the three metal treatments, while percentages of neutrophils and monocytes were increased. Respiratory burst activity was elevated in all metal treatments. Gill Zn concentration was highly variable, with no significant alterations occurring. Gill Cu concentration was elevated above control levels in all metal treatments. Gill Cu concentration in the two Cu/Zn treatments was also elevated above levels in the Cu control. Hepatic metal concentrations and MT levels were not altered from control values. Measurements of brain AChE indicated an elevation in this parameter across metal treatments. In general, alterations in physiological parameters appeared to be due to Cu, with Zn having no interactive effect. Copyright 1999 Academic Press.

Prometon has often been detected in surface water and groundwater in studies reported in the literature, but its presence is seldom discussed, partly because of its infrequent inclusion on lists of herbicides used in either agricultural or urban areas. In recent large-scale studies by the U.S. Geological Survey, prometon has been the most commonly detected herbicide in surface water and groundwater in urban areas and the third and fourth most commonly detected herbicide in groundwater and surface water, respectively, in agricultural areas. It also has been detected in rain. The frequent detection of prometon in the environment is discussed in relation to its use practices and predicted environmental behavior. Prometon is compared to atrazine, a structurally similar agricultural triazine herbicide that is one of the most studied and most commonly detected herbicides found in the hydrologic environment. The environmental data presented here demonstrate the wide-scale occurrence of prometon in all components of the hydrologic system, particularly in the surface water and groundwater of urban areas.

Two methods of inference commonly used in survey sampling (design-based and model-based) are described and illustrated using examples relevant in surveys of freshwater mollusks. The particular objectives of a survey and the type of information observed in each unit of sampling can be used to help select the sampling design and the method of inference. For example, the mean density of a sparsely distributed population of mollusks can be estimated with higher precision by using model-based inference or by using design-based inference with adaptive cluster sampling than by using design-based inference with conventional sampling. More experience with quantitative surveys of natural assemblages of freshwater mollusks is needed to determine the actual benefits of different sampling designs and inferential procedures.

However, the specific associations that mussels have with stream sediments are poorly understood, making it difficult to assess the impacts of changes in sedimentation rates on unionid mussels. Both bed and suspended materials, and concomitant changes in channel form associated with changes in sediment supply, may affect mussels in numerous ways at various stages in their life cycle. Considerable debate and uncertainty remains regarding the strength of associations between sediments and mussels, including whether increased sedimentation is a cause of recent mussel declines. It is important to be aware of appropriate procedures for sampling and analyzing fluvial sediments, and the nature of sediment sources, to adequately assess relationships between unionid mussels and fluvial sediments.

This paper presents results from the first part of a study that was designed to explore the role of an evolving hydrodynamic system in driving mass transport and chemical diagenesis, using the San Joaquin Basin of California as a field area. We use coupled hydrogeologic models to establish the paleohydrogeology, thermal history, and behavior of nonreactive solutes in the basin. These models rely on extensive geological information and account for variable-density fluid flow, heat transport, solute transport, tectonic uplift, sediment compaction, and clay dehydration. In our numerical simulations, tectonic uplift and ocean regression led to large-scale changes in fluid flow and composition by strengthening topography-driven fluid flow and allowing deep influx of fresh ground water in the San Joaquin Basin. Sediment compaction due to rapid deposition created moderate overpressures, leading to upward flow from depth. The unusual distribution of salinity in the basin reflects influx of fresh ground water to depths of as much as 2 km and dilution of saline fluids by dehydration reactions at depths greater than similar to 2.5 km. Simulations projecting the future salinity of the basin show marine salinities persisting for more than 10 m.y. after ocean regression. Results also show a change from topography- to compaction-driven flow in the Stevens Sandstone at ca. 5 Ma that coincides with an observed change in the diagenetic sequence. Results of this investigation provide a framework for future hydrologic research exploring the link between fluid flow and diagenesis.

This model ties together data on nutria population dynamics and feeding behavior from the literature with data from field studies on the phenology of Scirpus americanus and Spartina patens conducted in the Barataria Basin, Louisiana, USA in 1992. The complete model consists of three linked models: a model of nutria population dynamics (nutria model), a model of the annual marsh biomass cycle of Scirpus americanus and Spartina patens (biomass model), and a plant-biomass density-dependent marsh area model (area model). When all three models are linked together, they form the "nutria-biomass-area model." Analysis of the models indicated the following. (1) The high population densities and low survivorship rates as reported in the literature are incompatible. (2) The nutria model is sensitive to adult and juvenile survivorship and, to a lesser extent, young born per female. It is not particularly sensitive to gestation periods, impregnation rates, or time to maturity. (3) The marsh area model is not sensitive to the marsh loss equation nor to the density at which loss of marsh area begins but is sensitive to the amount of biomass destroyed per nutria. (4) Nutria numbers do not significantly decrease in the nutria-biomass-area model until the total marsh area approaches zero because marsh loss occurs only during winter when marsh biomass is at its annual low.

Rich. in Lake Chicot, Louisiana after 44 years of flooding AN - 17307683; 4547633 AB - Lake Chicot, in south central Louisiana, USA, was created in 1943 by the impoundment of Chicot Bayou. Extensive establishment of woody seedlings occurred in the lake during a 1.5 year period, including the growing seasons of both 1986 and 1987, when the reservoir was drained for repair work on the dam. Study plots were established in September 1986 to document woody vegetation establishment and to provide a baseline by which to monitor survival and growth after flooding resumed. Taxodium distichum seedlings were the dominant species after one growing season, with a maximum density of 50 seedlings/m super(2), an average of about 2/m super(2), and an average height of 75 cm. The lake was reflooded at the end of 1987, bringing water depths at the study plots up to about 1.4 m. Temporary drawdowns were again conducted during the fall of 1992 and 1996. In December 1992, the site was revisited, new plots established, and saplings counted and measured. There was an average of 2.1 T. distichum stems/m super(2), and the average height was 315 cm. After the 1996 growing season, there was still an average of about 1.9 stems/m super(2), and the average height had increased to 476 cm. Preservation of T. distichum forests in relatively shallow but continuously flooded areas such as Lake Chicot may be a simple matter of draining the lake after a good seed crop and maintaining the drawdown long enough for the seedlings to grow taller than the typical growing season water level. In the case of Lake Chicot, this period was two growing seasons. This action will mimic natural, drought-related drawdowns of the lake and will allow the seedlings to establish themselves and grow tall enough to survive normal lake water levels.

ER - TY - JOUR T1 - New method for the direct determination of dissolved Fe(III) concentration in acid mine waters AN - 16126473; 4518622 AB - A new method for direct determination of dissolved Fe(III) in acid mine water has been developed. In most present methods, Fe(III) is determined by computing the difference between total dissolved Fe and dissolved Fe(II). For acid mine waters, frequently Fe(II) >> Fe(III); thus, accuracy and precision are considerably improved by determining Fe(III) concentration directly. The new method utilizes two selective ligands to stabilize Fe(III) and Fe(II), thereby preventing changes in Fe reduction-oxidation distribution. Complexed Fe(II) is cleanly removed using a silica-based, reversed-phase adsorbent, yielding excellent isolation of the Fe(III) complex. Iron(III) concentration is measured colorimetrically or by graphite furnace atomic absorption spectrometry (GFAAS). The method requires inexpensive commercial reagents and simple procedures that can be used in the field. Calcium(II), Ni(II), Pb(II), Al(III), Zn(II), and Cd(II) cause insignificant colorimetric interferences for most acid mine waters. Waters containing >20 mg of Cu/L could cause a colorimetric interference and should be measured by GFAAS. Cobalt(II) and Cr(III) interfere if their molar ratios to Fe(III) exceed 24 and 5, respectively. Iron(II) interferes when its concentration exceeds the capacity of the complexing ligand (14 mg/L). Because of the GFAAS elemental specificity, only Fe(II) is a potential interferent in the GFAAS technique. The method detection limit is 2 mu g/L (40 nM) using GFAAS and 20 mu g/L (0.4 mu M) by colorimetry.

Prometon has often been detected in surface water and groundwater in studies reported in the literature, but its presence is seldom discussed, partly because of its infrequent inclusion on lists of herbicides used in either agricultural or urban areas. In recent large-scale studies by the U.S. Geological Survey, prometon has been the most commonly detected herbicide in surface water and groundwater in urban areas and the third and fourth most commonly detected herbicide in groundwater and surface water, respectively, in agricultural areas. It also has been detected in rain. The frequent detection of prometon in the environment is discussed in relation to its use practices and predicted environmental behavior. Prometon is compared to atrazine, a structurally similar agricultural triazine herbicide that is one of the most studied and most commonly detected herbicides found in the hydrologic environment. The environmental data presented here demonstrate the wide-scale occurrence of prometon in all components of the hydrologic system, particularly in the surface water and groundwater of urban areas.

Groundwater interacts with surface water in nearly all landscapes, ranging from small streams, lakes, and wetlands in headwater areas to major river valleys and seacoasts. Although it generally is assumed that topographically high areas are groundwater recharge areas and topographically low areas are groundwater discharge areas, this is true primarily for regional flow systems. The superposition of local flow systems associated with surface-water bodies on this regional framework results in complex interactions between groundwater and surface water in all landscapes, regardless of regional topographic position. Hydrologic processes associated with the surface-water bodies themselves, such as seasonally high surface-water levels and evaporation and transpiration of groundwater from around the perimeter of surface-water bodies, are a major cause of the complex and seasonally dynamic groundwater flow fields associated with surface water. These processes have been documented at research sites in glacial, dune, coastal, mantled karst, and riverine terrains.Original Abstract: Les eaux de surface sont parties integrantes des systemes aquiferes. Les eaux souterraines interagissent avec les eaux de surface dans presque tous les types d'environnements, depuis les petits ruisseaux, les lacs et les zones humides jusqu'aux bassins versants des vallees des grands fleuves et aux lignes de cote. Il est en general admis que les zones topographiquement hautes sont des lieux de recharge des aquiferes et les zones basses des lieux de decharge, ce qui est le cas des grands systemes aquiferes regionaux. La superposition de systemes locaux, associes a des eaux de surface, a l'organisation regionale d'ecoulements souterrains resulte d'interactions complexes entre les eaux souterraines et les eaux de surface dans tous les environnements, quelle que soit la situation topographique regionale. Les processus hydrologiques associes aux eaux de surface elles-memes, tels que des niveaux d'eau de surface saisonnierement hauts et l'evaporation et la transpiration de l'eau souterraine a la peripherie des eaux de surface, sont les causes essentielles de la dynamique complexe et saisonniere des nappes associees aux eaux de surface.

Analysis of tree cores from bald cypress [Taxodium distichum (L.) Rich], tupelo (Nyssa aquatica L.), sweet gum (Liquidambar stryaciflua L.), oak (Quercus spp.), sycamore (Platanus occidentalis L.), and loblolly pine (Pinus taeda L.) growing over shallow groundwater contaminated with cis-1,2-dichloroethene (cDCE) and trichloroethene (TCE) showed that those compounds also were present in the trees. The cores were collected and analyzed by headspace gas chromatography. Bald cypress, tupelo, and loblolly pine contained the highest concentrations of TCE, with lesser amounts in nearby oak and sweet gum. The concentrations of cDCE and TCE in various trees appeared to reflect the configuration of the chlorinated-solvent groundwater contamination plume. Bald cypress cores collected along 18.6-m vertical transects of the same trunks showed that TCE concentrations decline by 30-70% with trunk height. The ability of the tested trees to take up cDCE and TCE make tree coring a potentially cost-effective and simple approach to optimizing well placement at this site.

The impact of spray dredging on vegetated marsh and adjacent shallow-water habitat (formerly vegetated marsh that deteriorated to open water) was evaluated in a 0.5-ha Spartina alterniflora-dominated salt marsh in coastal Louisiana. The thickness of dredged sediment deposits was determined from artificial soil marker horizons and soil elevation change was determined from sedimentation-erosion tables (SET) established prior to spraying in both sprayed and reference marshes. The vertical accretion and elevation change measurements were made simultaneously to allow for calculation of shallow ( similar to 5 m depth) subsidence (accretion minus elevation change). Measurements made immediately following spraying in July 1996 revealed that stems of S. alterniflora were knocked down by the force of the spray and covered with 23 mm of dredged material. Stems of S. alterniflora soon recovered, and by July 1997 the percent cover of S. alterniflora had increased three-fold over pre-project conditions. Thus, the layer of dredged material was thin enough to allow for survival of the S. alterniflora plants, with no subsequent colonization by plant species typical of higher marsh zones. By February 1998, 62 mm of vertical accretion accumulated at this site, and little indication of disturbance was noted. Although not statistically significant, soil elevation change was greater than accretion on average at both the spray and reference marshes, suggesting that subsurface expansion caused by increased root biomass production and/or pore water storage influence elevation in this marsh region. In the adjacent shallow water pond, 129 mm of sediment was deposited in July 1996 as a result of spraying, and despite initial shallow subsidence and continual erosion through February 1998, water bottom elevation was raised sufficiently to allow S. alterniflora to invade via rhizome growth from the adjacent marsh. Hence, thin-layer deposition of dredged material at this site was effective at restoring and maintaining marsh elevation after 1.5 years. However, if the open water sediment deposits are not soon completely stabilized via further vegetative colonization, erosion may eventually lower elevations to the level where emergent vegetation cannot persist.

Previous studies have suggested uronic acids and O-methyl sugars may be useful indicators of microbial abundance and activity, but have been limited primarily to analyses of a small number of isolated samples. We report here comparative distributions of O-methyl sugars, uronic acids, and aldoses in sediment trap material and sediments from Dabob Bay, WA and nearby Saanich Inlet, BC, where temporal and spatial trends may be used together with well-established patterns in other biochemicals to identify bacterial contributions against the background of other carbohydrate sources. O-methyl sugars and uronic acids were important contributors to the overall flux and burial of polysaccharide material in Dabob Bay and Saanich Inlet, composing less than or equal to 12 wt% of the total carbohydrate yields from sediment trap and sediment samples. O-methyl sugars accounted for an average of 5% of the carbohydrate yields from sediment trap materials and sediments, but were found rarely and only in low abundance in vascular plant tissues, phytoplankton, and kelp. In contrast, uronic acids were abundant products of sediment trap material and sediments, as well as vascular plant tissues, where in some cases they predominated among all carbohydrates. Uronic acid abundance in sediment trap material averaged 3% and ranged to >6% of total carbohydrate yields. The persistence of total minor sugar yields in water column collections from Dabob Bay throughout the seasonal cycle indicated they had a primary source that was not directly related to plankton bloom cycles nor pulsed inputs of vascular plant remains. Subsurface maxima in total minor sugar yields (and several individual components) within sediment cores from both sites indicate in situ sedimentary sources. Taken together, the observed environmental distributions strongly suggest that the minor sugar abundances in Dabob Bay and Saanich Inlet were controlled by in situ microbial production.

The flood plains developed on relatively elevated sand and gravel deposits left within the channel by the 1978 flood. In cross section, the flood plains resemble benches with well-developed natural levees. Flood-plain growth occurred as sediment was draped onto preexisting surfaces in layers of sand and mud a few centimeters to decimeters thick, resulting in some lateral, but mostly vertical accretion. Annual and biannual measurements indicated that, as the flood-plain segments grew upward, the annual rate of vertical accretion decreased as the partial duration recurrence interval for the threshold or bankfull discharge increased from 0.16 to 1.3 yr. It is clear that a constant recurrence interval for overbank flow cannot be meaningfully assigned to this type of flood-plain ontogeny. These flood plains did not grow on migrating point bars, and vertical accretion at least initially occurred within the channel, rather than across the valley flat during extensive overbank flows. Sediments of these flood plains define narrow, elongated stratigraphic units that border the active channel and onlap older flood-plain deposits. These characteristics are considerably different from those of many facies models for meandering river deposits. Facies similar to those described in this paper are likely to be preserved, thereby providing important evidence in the geologic record for episodes of periodic channel expansion by ancient rivers.

We radio-tracked five paddlefish during three randomly chosen 24-h periods each month in May, August, and October 1995. Paddlefish were located by boat one to three times every 3 h during each 24-h period. At each location, geographic coordinates were determined with a global positioning system receiver using the Precise Positioning Service, and depth was measured with a depth sounder. Location coordinates were plotted with ARC/INFO software on a Geographic Information System land-water coverage. Movement distances were calculated as the linear distance between sequential locations. Radio-tagged paddlefish usually remained in a secondary channel that had low current velocity during all seasons, whereas main channel, main channel border, tailwater, and backwater habitats were seldom used. Paddlefish strongly selected areas that were deep; about 62% of paddlefish locations were in areas with more than 6 m of depth, although this habitat constituted only 14.5% of the total study area. However, paddlefish used significantly shallower areas during the night than during the day. Paddlefish moved significantly larger distances at night than during the day in spring and fall, but differences in movement among diel periods during summer were not significant. Our research suggests that radiotelemetry studies that need to determine depth use or movement of paddlefish during small time scales may need to incorporate a diel component.

Infiltrating waters exhibit anomalously high potassium to silica ratios resulting from dissolution of a potassium-rich glass that occurs as a trace phase in the rock. In laboratory experiments using rock from the field site, initial dissolution generated potassium-rich solutions similar to those observed in the field. The anomalous potassium release decreased over time (about 1 month), after which the dominant cation was calcium, with a much lower potassium to silica ratio. The anomalous potassium concentrations observed in the infiltrating soil solutions result from weathering of freshly exposed rock surfaces. Continual mechanical disaggregation of the rock due to segregation freezing exposes fresh glass to weathering and thus maintains the source of potassium for the infiltrating water. The ongoing process of creation of fresh surfaces by physical processes is an important influence on the composition of infiltrating waters in the vadose zone.

Characterizing the interaction between ground water and large lakes (e.g., the Great Lakes) is facilitated by the use of geochemical and isotopic data. In this study, pore waters were extracted from sediment cores collected from Saginaw Bay and the surrounding Saginaw lowland area; the geochemistry and stable isotope signature of these pore waters were used to identify sources for the water and solutes. Cores from Saginaw Bay and the Saginaw lowland area yielded strong vertical gradients in chloride concentrations, suggesting that a high-chloride source is present at depth. The spatial distribution of cores with elevated chloride concentrations corresponds to the regional distribution of chloride in ground water. Most of the Saginaw lowland area cores contain water with significantly lower delta super(18)O values than modern meteoric water, suggesting that the water had been recharged during a much cooler climate. The delta super(18)O values measured in pore waters (from Saginaw Bay cores) containing high chloride concentrations are similar to modern meteoric water; however, values lighter than modern meteoric water are encountered at depth. Chloride:bromide ratios, used to distinguish between different chloride sources, identify formation brine as the likely source for chloride. Transport models indicate that a combination of advection and diffusion is responsible for the observed Saginaw lowland area pore-water profiles. Pore-water profiles in Saginaw Bay sediments are produced primarily by diffusion and require significantly less time to evolve. An upward flux of solutes derived from formation brine could occur elsewhere within the Great Lakes region and significantly affect the geochemical cycling of chloride and other contaminants (e.g., trace metals).

I demonstrate the use of a two-step modeling approach to determine the implications of parasitism and nest predation for the population dynamics of songbird populations and to quantitatively evaluate alternative options for their management. I used a model to predict seasonal fecundity from parameters of nest success, productivity, and breeding season length (Pease & Grzybowski 1995) and a stage-based matrix model to examine population dynamics. I used this approach to model the population dynamics of the Puerto Rican Vireo (Vireo latimeri), a single-island endemic species that is exposed to high rates of parasitism by a nonnative brood parasite and to nest predation by introduced mammalian predators. The analysis showed that the introduction of the Shiny Cowbird (Molothrus bonariensis), rather than the mammalian nest predators, caused this population to become a "sink" and is probably the cause of recent population declines. Moreover, the analysis explicitly shows that knowledge of the relationships among parasitism, predation, and population growth rate can aid in designing an effective conservation strategy. This modeling approach can be used to determine the reproductive health of a population over a range of parasitism and predation values, to test alternative hypotheses for the cause of an observed population decline, and to make a priori predictions about the outcomes of specific management actions.

However, contaminant concentrations in tissue samples are subject to an inherently high level of variability due to differences in species, life stage, and gender bioconcentration potentials. Semipermeable membrane devices (SPMDs) were used to sample Aroclor 1254, a mixture of readily bioconcentrated polychlorinated biphenyls (PCBs), in a contaminated wetland near Flat Top, WV. The devices consisted of triolein, a lipid found in fish, enclosed in a polyethylene membrane. SPMDs were deployed in the water column and in direct contact with wetland sediments along a previously identified concentration gradient of PCBs. The devices were retrieved after a 25-day exposure period. Analytes were recovered by dialyzing the devices in nanograde hexane. Hexane dialysates were condensed and analyzed by gas chromatography. All deployed devices sequestered quantifiable amounts of Aroclor 1254. Water-column SPMDs accumulated PCBs far in excess of ambient water concentrations. The devices contacting sediments accumulated PCBs at all sites, though accumulated concentrations did not exceed concentrations in sediment. Patterns of PCB concentration in the devices corresponded to the identified gradient at the site. Results from the water-column SPMDs were used to estimate the concentration of the dissolved, bioavailable fraction of PCBs present in the water column. These concentrations ranged from 0.01 to 0.09 mu g/L of bioavailable Aroclor 1254.

The study reach includes perennial (uppermost and lowermost) subreaches and ephemeral subreaches of the lower Piru Creek and the middle Santa Clara River. The tracer-test data were used to calibrate a one-dimensional flow model (DAFLOW) and a solute-transport model (BLTM). The dye-arrival times at each sample location were simulated by calibrating the velocity parameters in DAFLOW. The simulations of dye transport indicated that (1) ground-water recharge explains the loss of mass in the ephemeral middle subreaches, and (2) groundwater recharge does not explain the loss of mass in the perennial uppermost and lowermost subreaches. The observed tracer curves in the perennial subreaches were indicative of sorptive dye losses, transient storage, and (or) photodecay - these phenomena were simulated using a linear decay term. However, analysis of the linear decay terms indicated that photodecay was not a dominant source of dye loss.

Photosynthetic pathway diversity was evaluated for the dominant species in a seasonally aquatic community in the south-western USA using super(14)C pulse-chase techniques. 2. Under submerged conditions, only about half of the species were clearly C sub(3), three of the 15 dominants were CAM, one species was C sub(4) and three were potentially assimilating carbon with both C sub(3) and C sub(4) fixation. 3. During the brief terrestrial stage in the life history of these amphibious plants, both the CAM and the C sub(3) + C sub(4) species switched to C sub(3), whereas the C sub(4) species did not switch. 4. Numerous variations were apparent; for example, the C sub(4) species, while exhibiting a biochemical pathway indistinguishable from terrestrial C sub(4) plants, lacked Kranz anatomy in the aquatic foliage. Also, despite well-developed CAM in several species, others exhibited low-level diel changes in acidity, apparently not indicative of CAM. 5. Species with C sub(4) or CAM CO sub(2) concentrating mechanisms lacked the capacity for bicarbonate uptake, an alternative CO sub(2) concentrating mechanism found in certain C sub(3) species in this community. 6. Rubisco/PEPC in aquatic foliage was higher in C sub(3) species than in C sub(4), CAM or putative C sub(3) + C sub(4) species. In the terrestrial phase, as expected, the switch from CAM or C sub(3) + C sub(4) to strictly C sub(3) assimilation was associated with a substantial increase in Rubisco/PEPC. Quite unexpected, however, was the substantial increase in this ratio in terrestrial C sub(3) foliage. It is hypothesized that submerged C sub(3) plants utilize PEPC for recycling of respiratory CO sub(2) and/or C sub(4) phototrophism under field conditions of limited CO sub(2) and O sub(2) saturation, and this is lost in the terrestrial foliage.

Generally applicable protocols for characterizing community diversity need to be developed to facilitate conservation. We used several multivariate techniques to analyze geographic variation in the composition of fish communities in Virginia streams. We examined relationships between community composition and six landscape variables: drainage basin, physiography, stream order, elevation, channel slope, and map coordinates. We compared patterns at two scales (statewide and subdrainage-specific) to assess sensitivity of community classification to spatial scale. We also compared patterns based on characterizing communities by species composition vs. ecological composition. All landscape variables explained significant proportions of the variance in community composition. Statewide, they explained 32% of the variance in species composition and 48% of the variance in ecological composition. Typical communities in each drainage or physiography were statistically distinctive. Communities in different combinations of drainage, physiography, and stream size were even more distinctive, but composition was strongly spatially autocorrelated. Ecological similarity and species similarity of community pairs were strongly related, but replacement by ecologically similar species was common among drainage-physiography combinations. Landscape variables explained significant proportions of variance in community composition within selected subdrainages, but proportions were less than at the statewide scale, and the explanatory power of individual variables varied considerably among subdrainages. Community variation within subdrainages appeared to be much more closely related to environmental variation than to replacement among ecologically similar species. Our results suggest that taxonomic and ecological characterizations of community composition are complementary; both are useful in a conservation context. Landscape features such as drainage, physiography, and water body size generally may provide a basis for assessing aquatic community diversity, especially in regions where the biota is poorly known. Systematic conservation of community types would be a major advance relative to most current conservation programs, which typically focus narrowly on populations of imperiled species. More effective conservation of aquatic biodiversity will require new approaches that recognize the value of both species and assemblages, and that emphasize protection of key landscape-scale processes.

Trial 1 involved capturing birds, transporting them on rough roads for 4 hr followed by holding in an aviary for 48 hr without overnight thermal support prior to release. Trial 2 involved capture, then holding in an aviary for 48 hr with overnight thermal support followed by transport for 4 hr prior to release. Trial 3 and 1 were identical except that overnight thermal support was provided during trial 3. We monitored survival, food consumption, weight change, and fecal production during captivity as well as changes in hematocrit, estimated total solids, heterophil to lymphocyte ratios, plasma uric acid, and creatinine phosphokinase (CPK) at capture and release. Survival was significantly lower for Amakihi during trial 1 (no thermal support). Birds that died lost significantly more weight than those that survived. Regardless of trial, birds responded to translocation by a combination of weight loss, anemia, hypoproteinemia, and elevated heterophil to lymphocyte ratio, uric acid, and CPK levels. The first 24 hr of captivity posed the greatest risk to birds regardless of whether transport or holding occurred first. Food consumption, fecal production, and weight all decreased at night, and overnight thermal support during holding was critical if ambient temperatures dipped to freezing. We recommend that if small passerines are to be held for > 12 hr, they be monitored individually for weight loss, food consumption, and fecal production.

Data on nesting eagles were collected at 58 to 72 nesting areas annually using two aerial surveys. Surveys were conducted during the incubation period to determine occupancy and nesting activities and late in the nestling period to count nestlings and determine nesting success. Annual occupancy rates of nesting areas did not vary significantly, whereas laying rates, success rates, and mean brood size varied significantly over the study period. Fledgling production for the study population varied sevenfold during the ten-year period. Laying rates, mean brood size, and overall population productivity were significantly correlated with abundance of cyclic snowshoe hare and Willow Ptarmigan (Lagopus lagopus) populations. Reproductive rates of Golden Eagles in Denali were similar to those of Golden Eagles from other high latitude study areas in North America, but lower than for Golden Eagles from temperate zone study areas in North America.

Our sampling period included two major droughts and associated crashes in Townsend's ground squirrel (Spermophilus townsendii) populations. The number of Prairie Falcon pairs found on long-term survey segments declined significantly from 1976-1997. Early declines were most severe at the eastern end of the NCA, where fires and agriculture have changed native shrubsteppe habitat. More recent declines occurred in the portion of canyon near the Orchard Training Area (OTA), where the Idaho Army National Guard conducts artillery firing and tank maneuvers. Overall Prairie Falcon reproductive rates were tied closely to annual indexes of ground squirrel abundance, but precipitation before and during the breeding season was related inversely to some measures of reproduction. Most reproductive parameters showed no significant trends over time, but during the 1990s, nesting success and productivity were lower in the stretch of canyon near the OTA than in adjacent areas. Extensive shrub loss, by itself, did not explain the pattern of declines in abundance and reproduction that we observed. Recent military training activities likely have interacted with fire and livestock grazing to create less than favorable foraging opportunities for Prairie Falcons in a large part of the NCA. To maintain Prairie Falcon populations in the NCA, managers should suppress wildfires, restore native plant communities, and regulate potentially incompatible land uses.

The debate over natural regulation combines elements of scientific disagreement with contrasting social values. Some scientists and range managers critical of natural regulation management have viewed the northern range as seriously eroded and overgrazed due to an overpopulation of elk. Data, and the interpretations thereof, have been published supporting this viewpoint. Other scientists have challenged this opinion with the results of longer term studies and disparate interpretations of data gathered by the critics. Contrasting social values range from support for the "hands-off" management policy for ungulates in Yellowstone National Park to limiting ungulate populations to prevent eminent deterioration of the range. It is the opinion of the authors that extensive published data support the position that current elk populations and sympatric herbivores do not exceed the ecological carrying capacity of the northern range; therefore, the range is not overgrazed by ecological standards. The discourse over science-driven and value-driven opinion will, and should, continue: neither scientific thinking nor social values are immutable.

This database contains spatial data for the vegetation communities within approximately 1.2 million hectares (ha) of South Florida's wetlands. The area covered includes Everglades National Park, Big Cypress National Preserve, Biscayne National Park, the Florida Panther National Wildlife Refuge, and the south Florida Water Management District Water Conservation Area 3. This detailed delineation of vegetation in the preserved lands of south Florida allows for the first time a quantitative analysis of Everglades vegetation data at the plant community level. In addition to this spatial database, several subset study areas have been identified in areas of special environmental interest for interpretation of large-scale aerial photographs and the development of high-resolution vegetation data sets. Together, these Everglades vegetation mapping efforts provide a baseline for establishing trends and monitoring changes related to the restoration and preservation of the Everglades.

Radio-collared deer were tracked for 1 to 3 years (1989-1992) to identify relative exposure to contaminants based on telemetry locations plotted on grid maps depicting known soil contaminant concentrations. At the end of the study, all animals were in fair or good body condition at the time of necropsy. Mean ages of mule deer and white-tailed deer were 7.4 (range 4-12) and 10.6 years (range 5-17), respectively. At necropsy, tissues were collected from the deer for serology, histopathology, and analysis for eight chlorinated hydrocarbons and two metals. Detectable residues of mercury were found in the kidneys of 10 deer (range 0.055-0.096 mu g/g), dieldrin was found in fat (n = 9) (range 0.02-0.72 mu g/g), liver (n = 4) (range 0.017-0.12 mu g/g), and brain (n = 1, 0.018 mu g/g), and DDE was found in the muscle of one animal (0.02 mu g/g). Relative exposure estimates derived from telemetry and soil contamination data were correlated with tissue levels of dieldrin (p < 0.001) and mercury (p = 0.05). Two mule deer had severe testicular atrophy, and one of these animals also had antler deformities. The prevalence of antibodies against epizootic hemorrhagic disease serotype 2 was 85%.

We describe an approach to evaluating carnivore habitat that uses pre-existing qualitative and quantitative information on humans and carnivores to generate coarse-scale maps of habitat suitability, habitat productivity, potential reserves, and areas of potential conflict. We use information pertinent to the contemplated reintroduction of grizzly bears Ursus arctos horribilis into central Idaho to demonstrate our approach. The approach uses measures of human numbers, their estimated distribution, road and trail access, and abundance and quality of bear foods to create standardized indices that are analogues of death and birth rates, respectively; the first subtracted from the second indicates habitat suitability (HS). We calibrate HS to sightings of grizzly bears in two ecosystems in northern Idaho and develop an empirical model from these same sightings based on piece-wise treatment of the variables contained in HS. Depending on whether the empirical model or HS is used, we estimate that there is 14 800 km super(2) of suitable habitat in two blocks or 37 100 km super(2) in one block in central Idaho, respectively. Both approaches show suitable habitat in the current Evaluation Area and in an area of southeastern Idaho centered on the Palisades Reservoir. Areas of highly productive habitat are concentrated in northern and western Idaho and in the Palisades area. Future conflicts between humans and bears are most likely to occur on the western and northern margins of suitable habitat in central Idaho, rather than to the east, where opposition to reintroduction of grizzly bears is currently strongest.

Chloride concentration in the stream has increased by over an order of magnitude during the 23 yr since the highway was opened, and chloride concentration in the lake has tripled. Road salt moves to the lake primarily via the contaminated stream, which provides 53% of all the chloride to the lake and only 3% of the total streamflow to the lake. The stream receives discharge of salty water from leakage through the diversion berm. Uncontaminated ground water dilutes the stream downstream of the berm. However, reversals of gradient during summer months, likely caused by transpiration from deciduous trees, result in flow of contaminated stream water into the adjacent ground water along the lowest 40-m reach of the stream. This contaminated ground water then discharges into the lake along a 70-m-wide segment of lake shore. Road salt is pervasive in the bedrock between the highway and the lake, but was not detected at all of the wells in the glacial overburden. Of the 500 m of shoreline that could receive discharge of saly ground water directly from the highway, only a 50-m-long segment appears to be contaminated.

AN - 69668015; 10188201 AB - Free-ranging wildlife is regularly exposed to pesticides and can serve as a sentinel for human and environmental health. Therefore a comprehensive pesticide hazard assessment must incorporate the effects of actual applications on free-ranging wildlife. Mortality is the most readily reported wildlife effect, and the significance of these data can be realized only when placed in context with the factors that affect the gathering of this type of information. This paper reviews the variables that affect the collection of wildlife mortality data. Data show that most effects on wildlife are not observed, and much of observed mortality is not reported. Delays in reporting or in the response to a report and exposure to multiple stressors distort the exposure-effect relationship and can result in uncertainty in determining the cause of death. The synthesis of information strongly indicates that the actual number of affected animals exceeds the number recovered.

The crown pillar, defined as the rock remaining between the uppermost extent of mining and the base of surficial glacial deposits, is to be left in place to protect the surface and the glacial aquifer system. Hydrologic stability refers to potential changes in vertical hydraulic conductivity resulting from mining. Changes in hydraulic conductivity could result from mechanisms which include collapse of the crown pillar, joint movement, or strain changes in the crown pillar. The issue of hydrologic stability of the crown pillar had been raised by the Department of Natural Resources (DNR), State of Wisconsin, as a potential concern because of solute release to the groundwater regime after reflooding the backfilled mine. To address this issue, a series of two-and three-dimensional numerical analyses were conducted to predict the impact of mining to the crown pillar for the worst possible scenario. A three-dimensional simulation of the entire mine area was first conducted to evaluate the stress and strain changes in the crown pillar. A detailed analysis for selected locations within the crown pillar was then used to investigate the potential of joint shear and joint interaction. Maximum allowable strain, safety factors against joint slip, and change of hydraulic conductivity in the crown pillar were evaluated. A minimum crown pillar thickness of 100 ft was established based on the analysis results. The numerical analyses concluded that there will be no measurable impact to the hydraulic regime due to mining.

The following results were obtained: 1) The linear compressibilities decreased in a non-linear manner as the effective stress increased. The rate of decrease is greatest at lower effective stresses. 2) Anisotropy, measured as the ratio between the linear compressibilities perpendicular and parallel to the bedding plane, is greatest at low effective stresses for the drained and undrained pore fluid boundary conditions. The unjacketed compressibility shows little anisotropy. As the effective stress increases, the anisotropy decreases until the sample behaves isotropically at the higher effective stresses. These data were also used to calculate pore compressibilities as a check of the assumption that the grain compressibility equals the pore compressibility.

Material behaviour is modelled by large strain elastoplastic deformation theory of the Drucker-Prager solid. Stability analysis is carried out along the primary equilibrium path to examine possible emergence of bifurcations that may lead to different failure modes. The model is used to investigate the effect of bifurcation modes on the initiation of a tensile fracture and to interpret the experimental results obtained from fracturing tests on thick-wall cylinders.

The project concerns an assessment of stability of a mountain slope affected by a deep-seated deformation phenomenon. An important national highway runs along the toe of the slope and two penstocks for a hydroelectric scheme are founded on one section of the slope. The annual rate of movement of the overall slope during the past 15 years varied between 1.5 and 2 cm. The methodology developed and used for characterizing the behavior of the rock mass associated with the example slope should be useful in defining the degree of confidence with which a very large engineering project may be realized in a very large rock mass, within the given constraints of budget, time, and environment.

As the depth at the project site increases, the underground temperature tends to elevate. This study aims to develop a reasonable methodology for estimating underground rock temperature under deep overburden. This paper proposes a methodology of modular analysis for estimating deep underground rock temperature. The proposed methodology involves the finite-element method and nonlinear optimization method. The proposed analysis assumes that the distribution of underground temperature is solely due to two-dimension thermal conduction. After verification, numerical experiments demonstrate that the distribution of underground temperature significantly depends on the thermal conductivity of underground rock. Parametric study illustrates that the anisotropy of thermal conductivity and the topography of ground surface also affect the distributions of temperature and thermal gradient. This study also discusses the sources of error for estimating the underground temperature.

One wall of the quarry is 230 feet high, and the face overhangs with a dip of 65 degrees. This wall presented a potentially unstable condition during rapid drawdown. Failure of this wall would bury the crime scene and prevent retrieving evidence. Our objective was to maximize the drawdown rate without failing the quarry wall. This paper describes our evaluation of the wall stability, the maximum safe rate of drawdown, the instrumentation used to monitor the wall stability, and the procedures used and strategic changes made during drawdown.

To utilize the gravitational flow of blasted ore and caved waste rock, sublevel caving mining method will be adopted. Expected ore extraction is about 85% of ore deposit. One of the important characteristics of mine is that rock quality designation varies in the ore body. The stability of the opening in this mine must be well maintained, even though geology is relatively soft and highly fractured. For the stable mining operation, location of the stope and drifts is very critical. Also, it is very important to understand stress distributions around sublevel drifts and stope to maintain stability of mine opening and to determine mining sequence. The prime objective of this study is to develop a useful method for designing stopes and drifts in soft, weak, and highly fractured metallic ore deposits.

Artificial anisotropic rock specimens were cored with different dip angles from interlayered and stratified blocks. The Young's moduli of rock masses with different dip angle were simulated using the imperfectly bonded interface constitutive law developed by Tien et al. (1995). The simulation results based on the imperfect bonded models agreed well with the experimental results.

Sand production experiments on thick wall cylinder sandstone specimens with radial fluid flow were performed in a variety of sandstones to correlate the productivity with the applied external stress, the deformation of the inner hole and the amount of produced sand. Theoretically, the productivity in the thick wall cylinder test and in an open hole well were analyzed by distinguishing between the pre-sand production phase, where permeability changes due to the applied stress dominate the productivity changes, and the post-sand production phase where geometry changes due to sand removal dominate.

BSM simulates the discontinuous rock masses or large displacement by assembling blocks divided by joints and faults. The 2-D version of the BSM has been applied to many mining and rock mechanics cases and proved to be a useful tool for jointed rock analysis The paper presents the formulation and solving procedures of the 3-D modeling technique. A closed form solution and an illustrated example are presented to demonstrate the reliability and capability of the model.

The probabilistic analysis as well as its localization was achieved through the probabilistic characterization of the in-situ strength values, that provide the full statistical distribution of strength variables at every point within the geological formation. An actual case study was made for a surface coal mine to demonstrate its superiority and to show its technical details.

The basic concept for deep geologic disposal and the role of bedrock in the design process are described in brief. In the overall disposal context, it is necessary to have a holistic approach and consider the complete system model of Geology (G), Thermal processes (T), Hydrogeology (H), Mechanical processes (M), Chemical processes (C) and Engineering activities (E). The strategy of incorporating rock mechanics data in five different stages of a waste disposal programme are presented. From a list of activities, existing gaps in the information and knowledge can be identified and research needs can be prioritised.

The limit equilibrium procedure involves contouring excess sliding forces on a stereo net for different excavation orientations. Data from a tunnel at Theodore Roosevelt Dam is used to demonstrate the procedure. Results indicate that stability of removable blocks is highly dependent on the excavation's orientation and the roughness of joints. Estimated support forces are conservatively based on the maximum key block. The advantage of this technique is that the geometry and vector equations are easy to solve allowing many cases to be examined. Its application is limited to blocky rock masses with continuous jointing in low stress conditions. The main finding from this work is that additional research is necessary for characterizing the roughness of joints.

The main objective of this research is to establish if the occurrence of the two failure modes observed in rock cutting experiments (ductile at small depth of cut, brittle at large depth) can be duplicated in numerical simulation. The numerical analysis is carried out with the discrete element code PFC (super 2D) which models solids as a collection of bonded disks. Scaling laws are first established between the micro-properties at the particle scale (such as the mean particle radius, and bond strengths) and the apparent material properties at the macroscopic scale (such as the compressive strength sigma (sub c) and the toughness K (sub Ic) ). Cutting tests are then performed with a particle assembly of rock-like properties.

In this paper, the distribution pattern of gas pressure surrounding the mining area is studied. Particular considerations are given to the varying coal permeability resulting from the abutment pressure and to the dynamic feature of the flow-field structure associated with mining face advance. In a case study, numerical modeling using a finite element program was conducted to calculate the gas pressure in the coal seams with varying coal permeability and at different cycles of face advance. The results show that the modeled gas pressure agreed well with the field measurements. Smaller advance distance in a mining cycle would cause less change of gas pressure.

Two strain-gauged rock bolts were grouted into the middle of the rib next to the face. The drift was excavated in three advances, each one-half drift wide. Strains were recorded hourly by a datalogger. Results show that the average change in axial bolt strain for the first and second advance was about the same and that there was almost no change in strain after the third advance. Bending strain was observed 19 cm from the head of the bolt.

For different values of the input parameter of the variogram method (lag distance, h), D and another associated fractal parameter K (sub v) were calculated for the aforementioned profiles. The estimated K (sub v) was found to relate to D, sigma and d according to Kv = 2.0X10 (super -5) d (super 0.35) sigma (super 1.95) D (super 14.5) . The parameter K (sub v) can be used to capture the scale effect of roughness profiles. Suitable ranges for h were estimated to obtain computed D within + or -10% of the D used for the generation and also to satisfy a power functional relation between the variogram and h. Results indicated the importance of removal of global trend for roughness profiles with global trend to obtain accurate estimates for the fractal parameters. The parameters D and K (sub v) are suggested to use with the variogram method to quantify stationary roughness. In addition, at the basic level, the mean inclination/declination angle of the surface in the direction considered can be used to represent the global trend. Procedures are given in the paper to estimate suitable h range for a given natural rock joint profile to use with the variogram method to estimate D and K (sub v) accurately for the profile.

To progress expeditiously, the research had been pursued in an empirical direction aiming to rationalize the accumulated experience of miners. Some 125 mining case histories, including 27 failed and 98 unfailed examples, had been accumulated. The critical safety factor of pillars was assumed to be a random variable, quantified by the lognormal distribution with its median at unity. Constants in a strength formula were derived from the data, using the tributary area pillar load, a simple three-parameter formula for pillar strength and the statistical method of the maximum likelihood. The results were published in 1966 and the design method based on them has been utilized almost exclusively in the intervening 32 years. Finally, some weaknesses and outstanding problems are discussed. JF - Proceedings - Symposium on Rock Mechanics AU - Salamon, M D G A2 - Amadei, Bernard A2 - Kranz, Robert L. A2 - Scott, Gregg A.

Equipment used included the Menard type tri-cell pressuremeter and Cambridge high-pressure dilatometer. The test data were interpreted using some of the existing empirical and a newly developed analytical procedure. According to the interpretations of PMT data, the tested weak rock should behave as a highly overconsolidated cohesive material. This is contrary to some of the available laboratory experimental results. A 3-surface numerical scheme has been developed to simulate pressuremeter expansion in weak rock with unload-reload cycles. Preliminary results have indicated that the numerical scheme is capable of capturing the important features of pressuremeter expansion in a weak sandstone.

The excess pore pressure reduces the effective confining pressure applied to the material and leads to less stable wellbore conditions. The excess pore pressure response is also time-dependent, due to fluid flow associated with non-uniform pore pressure distribution in the material. The flow changes the effective stresses and induces further deformation of the wellbore. This paper describes two numerical models, one is a time-dependent model that incorporates coupled flow-mechanical interaction and another a steady state time-independent analysis that only accounts for mechanically induced pore pressure. Predictions from the two models are compared with the results of a borehole collapse test on thick-walled hollow cylinder of a soft shale. The investigation shows that there are large differences between predictions obtained from the two numerical models. The coupled numerical model is shown to be in reasonable agreement with the results of the laboratory tests.

Finally, we developed block theory which more naturally accommodates the three dimensional aspects of structural geological data. The original assignment to analyze the Pile Driver test drifts at the Nevada Test Site, based on joint trace mappings, would have been better served with the block theory approach.

Longwall panels at depths in excess of 610 m (2000 ft) have been successfully retreated. Visual observations and stress measurements indicate that load transfer distances greater than 229 m (750 ft) have been experienced in the west side panels off the 3 (super rd) North mains. During retreat of longwall panels, ground conditions deteriorated significantly in the development section for the next longwall in the sequence located approximately 229 m (750 ft) away. Deteriorated ground conditions included a pillar burst, floor heave, rib spalling, and roof falls. Stress measurements suggest 13% excess load near this gateroad over the anticipated vertical stress. The long load transfer distances observed are believed to be primarily due to the massive and strong Castlegate Sandstone in the overburden strata.

This study has been primarily carried out numerically, and to a certain extent, in the field. However, since the rock properties are generally tested in the laboratory, this last situation needs to be modeled to maintain consistent scales in the analysis. In this paper, concepts and techniques of laboratory experiments are presented to determine relationships between: (a) fracture aperture and external loading in simulated rocks (concrete); and (b) flowrate and external loading in simulated fractured blocks (concrete).

This, in turn, affects the flow characteristics of coal and, hence, the overall production. This paper describes appropriate laboratory techniques to estimate different compressibilities of coal: bulk, matrix, pore volume and matrix shrinkage. The impact of compressibility on gas production is also evaluated. The results show that bulk and matrix shrinkage compressibilities are much larger compared to matrix, or grain, compressibility. The simulation results show that including pore volume compressibility results in a decline in production of about 15% over a five-year period. Including matrix shrinkage compressibility, on the other hand, increases the production over the same period by almost 50%. Furthermore, reduction in the overall bulk volume of coal as a result of matrix shrinkage compressibility effect may also be resulting in a significant decrease in the effective stress and thus increased permeability.

Tensile fractures initiate at the wellbore wall at P (sub frac) , they link up to form large axial fractures sub-parallel to the wellbore axis at P (sub link) , and they propagate away from the wellbore at P (sub grow) . In general, our modeling shows that P (sub frac) and P (sub link) can be maximized by drilling the wellbore in an optimally stable orientation, and P (sub grow) can be maximized by using "non-invading" drilling muds, that is, those that prevent fluid pressure from reaching the fracture tip (i.e., if solids in the mud form bridges within the fracture).

It takes into consideration the factors which determine the degree of complexities required in developing mud weight program to provide the required effective mud support with time. A range of design and analysis tools required for wellbore stability analysis is described systematically. The application of some of the tools is demonstrated through two field case studies to develop strategies to control shale instability in wells drilled in the North West Shelf of Australia. The tools provide a practical means of optimising the approach in developing the solution, including drilling fluid design (weight, type and chemistry), to manage shale instability efficiently.

The caving angle at the goaf edge, primarily depending on the roof type and depth of cover, is about 25 degree (or low) in a manner that a relative thin thickness (sometimes as low as "razor sharp" edge) of rock suddenly may over-ride the breaker-lines. This phenomenon, known as the feather-edging goaf-fall, is common in Australia (mostly in Western and Northern Coalfields), South Africa and USA. These goaf-falls are major source of injury & fatality accidents and are reasons for burial incidents of continuous miners. To alleviate such feather-edging, the alternatives may be by use of Mobile breaker lines, longwall chocks and fully grouted bolted breaker lines at goaf-edges. This paper finds the last alternative as viable and practicable. The results and analysis of data from "instrumented" bolts validate this proposition.

Unfortunately this improved productivity was often accompanied by significant dilution. The development of larger capacity mobile underground equipment, which directly contributed to the development of higher productivity, higher tonnage, mining methods, requires larger underground access infrastructure. These and other factors necessitated that significant improvements be made in the area of basic ground control and rock engineering. This paper reviews some key rock engineering developments from the past 15 years and how these impact modern underground mine design.

The rock specimens employed in this study were made according to the Short Rod (SR) specimen suggested by ISRM. The experimental results showed that under the dynamic loading condition the fracture toughness of both the gabbro and the marble increased with increasing loading rates. This relationship between fracture toughness and loading rates is fairly similar to that obtained in the normal room temperature environment. It can be concluded that temperature variation hardly affects the values of dynamic fracture toughness of the two rocks. This is completely different from the result obtained under the static loading condition.

However, few publications referred to residual strength behavior of anisotropic rocks. A laboratory testing technique, called the multiple failure state of triaxial test, was adopted to evaluate the residual strength behavior of anisotropic rocks in triaxial compression. A series of tests was performed on core samples of argillite. The experimental results show the fact that the triaxial residual strength is directly related to the inclination angle of specimen foliation with respect to the axial loading direction. The minimum triaxial residual strength occurs in the specimen with 30 degrees of inclination angle; and specimens with 0 degrees or 90 degrees inclination have maximum triaxial residual strength. Analyzing the experimental data by the basis of the Mohr-Coulomb failure criterion, the residual cohesive strength strongly depends on the inclination of foliation. Nevertheless, the residual friction angle is independent of the inclination of foliation. A new failure criterion of triaxial residual strength for anisotropic rocks, modified from the Hoek and Brown failure criterion, is proposed in this paper. The criterion correlates closely with the experimental data of argillite specimens and can be extended to estimate the triaxial residual strength for inherent anisotropic rocks with discontinuities.

This paper presents an alternative method of predicting uplift and seepage at the base of concrete gravity dams. A sensitivity analysis was carried out to study the importance of several parameters on dam stability such as the orientation, spacing, and location of discontinuities. The effectiveness of drains in reducing uplift and increasing dam stability is also investigated. The study shows that joint water flow and adverse geological conditions could result in unusual uplift at the base of concrete gravity dams, well in excess of what is predicted with the classical linear or bi-linear pressure assumption. Drains can be very effective in reducing that uplift if their location and diameter are chosen properly. It is shown that, in general, the DDA program with the hydro-mechanical algorithm can be used as a practical tool in the design of gravity dams built on fractured rock masses.

A new base friction testing procedure was used requiring the derivation of a numerical algorithm to convert base-friction time to gravity time. Results show that the base friction model correctly predicts the real behavior of the block. Furthermore, in all the cases presented, the time-scale equation applies at least approximately in pure rotation and pure sliding cases. Its validity in cases involving sliding and toppling simultaneously and in other more general cases is inconclusive due to insufficient data.

Three experimental methods are presented in this paper to evaluate the poroelastic factor of rock specimens. The first technique consists of determining matrix and bulk compressibilities using hydrostatic tests. The second technique involves hydrostatic and depletion tests performed on identical samples providing the poroelastic factor as a function of effective stress. The third technique involves constructing the failure envelope on samples with zero pore pressure and one triaxial test with pore pressure. The last two methods provide comparable results that do not require measurement of sample compressibilities. This paper discusses the detailed experimental procedures of proposed methods.

This model is coupled to a discontinuum model (Discontinuous Deformation Analysis (DDA)) introduced by Shi (1988) and used to simulate a single blasthole bench geometry. It is assumed in the model that the rock is already fragmented in-situ due to the intersection of pre-existing discontinuities and the action of stress wave. Hence, the model only considers the gas pressurization phase of the blasting process. The gases are assumed to expand adiabatically using an equation of state for the products of detonation. The gas loading components on each block are computed by minimizing the total potential energy induced to the block due to a uniform loading of block edges.

The most obvious discontinuities are joints and fractures which can be observed in exposures and rock cores. Just as significant are discontinuities due to changes in stiffness resulting from lithology and fracture density. Discontinuities within the rock mass are typically taken into consideration using well established procedures for rock mass classification. By extending this procedure to classify individual strata rather than the overall rock mass, and using empirical correlations, it is possible to estimate a stiffness for each stratum. Measurements have verified modeled behavior of horizontally bedded sedimentary rock overlying high extraction coal mine panels. The locations and magnitudes of simulated displacements are consistent with those measured using time domain reflectometry (TDR). The importance of incorporating variations in rock stiffness and plastic sliding along "stiffness discontinuities" into numerical models has been confirmed by experience with TDR monitoring on many projects.

The morpho-mechanical behavior was analyzed in order to better understand the cyclic behavior of these joints. One parameter was defined to quantify the degradation of the sheared joints. Two models were then proposed to predict the degradation of the anisotropic joints according to the loading conditions (CNS or CNK) and the shearing mode (monotonous or cyclic). The degradation model for the CNK condition was generalized for both loading conditions and this model is in agreement with the undulated joints test results.

Specifically, phenomena related to osmotic and poroelastic processes are included. A generalized plane strain solution is utilized which fully couples the chemical potential and deformation of shale. Drilling fluid parameters such as mud weight and salt concentration can be optimized to alleviate borehole instability when using oil-based or water-based muds. The user can choose the Drucker-Prager failure criterion or the Mohr-Coulomb criterion when conducting stability analyses. The model was used to investigate the impact of drilling fluid chemistry on the stability of an inclined wellbore in shale. The results demonstrate that osmosis significantly impacts fluid flux into the formation whereby stability can be achieved by increasing the salinity of the drilling mud. However, the contribution of osmosis to hole stability is overestimated by the ion exclusion model. Preliminary results of a boundary element model with ion transfer indicate that the diffusion of ions progressively decreases and eventually eliminates osmosis by reducing the chemical potential gradient between the mud and the formation.

The test programme was designed to match as closely as possible the in-situ conditions and consisted of four series of P&S-wave velocity measurements. Series A was isotropic loading of the dry specimen at room temperature. Series B was isotropic loading of the dry specimen at a temperature of 120 degrees C. Series C was isotropic loading of the specimen saturated with decane at room temperature. Series D, simulating the in-situ stress path, imposed uniaxial strain compression (K (sub 0) -conditions) on the specimen, saturated with brine at a temperature of 120 degrees C while pore pressure was reduced from 48.3 to 20.7 MPa (7000 to 3000 psi), and followed by displacement of mobile water by decane. The results showed that P&S wave velocities depend on temperature, effective stress level, initial porosity and saturation fluid. A new computer program for logging and analysing acoustic signals developed at NGI is described.

An area measuring approximately 1 by 2 km (2800 by 7200 ft) collapsed abruptly without warning. This paper describes the resulting mine damage, airblast, gas emissions, and seismic event. The collapse is analyzed in terms of a cascading sequence of pillar-floor failure using established principles of failure stability. The dynamic nature of the failure is thought to stem from geological and mine geometry factors resulting in a "soft" pillar-loading system. While the specific mechanism initiating the collapse has not been identified conclusively, four candidate mechanisms are considered. Design methods to decrease the potential for large-scale collapse are summarized, and limitations in our ability to evaluate both the stability of old workings and long-term performance of new designs in this setting are described.

The theory and the mechanism of modeling rock failure in DDA is briefly introduced. The factor of safety is directly defined based on the failure mechanism and is easily to be obtained in DDA calculation. Two practical applications have been presented to show how to use the method in practice. One application is the simulation of a slope rock mass collapse happened in Hokkaido, Japan. The other is rock fall simulation of a slope located in Niigata, Japan. It has been shown from two practical applications that DDA is a very effective numerical method for slope stability analysis.

AN - 52425197; 1999-068658 AB - In contrast to classical logic systems, fuzzy logic is a technique of reasoning by "cheap" approximations, significance and human-like terminologies rather than by the "expensive" exactness and precision. The technique is based on the fuzzy set theory and is considered a handy tool for quantifying vagueness. This paper combines the fact that sanding can sometimes benefit the well-reservoir system with the need to keep its intrusion into the wellbore at a tolerable level to create a fuzzy sanding controller. The system monitors the sanding level and its rate of change; and adjusts the choke valve accordingly. Fuzzy logic resulted in a smooth/continuous solution no matter how the input varied within the universe of discourse (domain) and/or crossed boundaries between (fuzzy) sets. Thus, the technique allowed the machinery to operate in small refinements, avoided creating any abrupt changes to the drawdown, and secured the stability of the system.

In reality, the pore fluid boundary conditions at the walls may be much more complicated. This paper presents the newly-developed poroelastic solution for inclined boreholes with time-dependent pore pressure or the pore fluid flow at the wall. The effects of the pore fluid boundary conditions on the borehole stability are also analyzed.

Some of the shale samples for triaxial tests were treated with filtrates of two water-based muds with different KCl concentrations at elevated pressure and temperature. The triaxial tests were performed undrained at a range of effective confining pressures. A series of borehole collapse tests was conducted on thick-walled cylinders of the same shale material. Mud filtrate was circulated along the borehole wall at a zero average overbalance pressure in some of the tests before the borehole pressure was reduced to induce borehole failure, while the cell pressure was maintained constant. Comparison of the triaxial test results on treated and untreated samples showed that the treated samples have higher modulus and peak strength but lower Poisson's ratio and Skempton's pore pressure parameters A and B than those untreated samples. The extent of the effects, attributable to chemical potential mechanism, was different for the two water-based muds. The thick-walled cylinder test results showed that the mechanism resulted in a significant increase in wellbore stability due to a combination of increase in effective mud support and material strength.

The method uses high-pressure foam to initiate, pressurize and propagate controlled fracturing in rock. The foam is injected to the bottom of a relatively shallow pre-drilled hole in the rock or concrete to be broken by means of a barrel incorporating a hole bottom sealing method. The high viscosity of the foam (as compared to a gas) combined with its stored energy characteristics (as compared to a liquid) result in consistent and controlled breakage. The pressures required to fracture and excavate rock are significantly less than required in methods based upon the use of small explosive or propellant charges. Airblast and flyrock are reduced to very benign levels, allowing the method to be applied in a continuous manner and to be used in urban and other sensitive environments.

Historically, field tests had been conducted against various obstacles and two test bores 3.5 m in diameter were excavated into granite, one of which was taken to a test depth of 17 m. A cost analysis had been performed using the experimental data collected from the program in the 1970s. Advance rates that were limited only by the estimated ability to remove muck were assumed in this analysis. These assumptions lead to boring rates that were not only more than three times faster than conventional drill and blast techniques but also considerably cheaper. The economic analysis has been recomputed with the aid of empirical cost functions from the US Bureau of Mines. It has been found that under certain circumstances the REAM technique uses less propellant per kilogram of ore produced than conventional drill and blast methods. Also, if cost is not an issue then the REAM technique can provide advance rates unobtainable by conventional methods.

Therefore, dynamic key block stability is of primary concern in the densely fractured East and North rock slopes of the mountain. Recent seismogenic key block motions in the East face, detected by our in-situ monitoring system, are explained by the presently low factor of safety against sliding, and by a pronounced topographic site effect at Masada with peak spectral amplification of about 3.5. Two analysis methods are employed: 1) Static and pseudo-static limit equilibrium analysis of removable key blocks in the East face where failure of large individual key blocks is of primary concern; 2) Static and true dynamic DDA modelling of a stochastically generated block mesh in the North face where the collapse of complete slope segments under dynamic loading is of concern. The deterministic analysis of removable key blocks in the East face reveals that when joint water pressures are considered application of a 2D solution proves unconservative. DDA modelling reveals the expected failure modes in the North face and the maximum depth of deformation as a result of dynamic loading.

Field tests are underway in mines in Idaho and Montana. Strains measured on structural support members in an ore pass provided information about total forces acting on the structure as material was dumped into it. Results show that measured static loads were considerably less than actual total weight of the material dumped and that dynamic loads were subject to many factors, such as effects of blasting to remove hang-ups. Comparisons of measurements and computer results using a particle flow code indicated that several difficulties remain before achieving realistic determinations and models of the dynamic effects of particle flow in ore passes and impact loads on the gates. Impact loads were overestimated in computer analyses as compared to loads measured in field tests. An alternative design approach based on softening the chute and control gate assembly is being proposed.

The asperity can interlock with the opposite fault face along the shoulder protruding from the wall, or can make frictional contact (perhaps smaller scale interlocking) all along the face of the brick. A finite difference approximation to the biharmonic equation is used for a two-dimensional analyses of asperity stresses resulting from interlocking and confining forces. Approximations of Coulomb's equation are used to estimate shear strength vs confining stress. Applying force all along the brick face is a less efficient method of stressing the brick at probable sites of rupture initiation than is interlocking the brick at the protrusion shoulder. Failure initiation of the asperity by shear stress seems likely to occur most often. Under some circumstances, considering the uncertainties of shear and tensile strength at depth, failure initiation by tensile stresses may be possible.

This is a procedure for formally examining modeling and design to ensure that they have captured the essence of the problem in hand. The main subject areas in rock mechanics are reviewed and the modeling problems highlighted. A range of engineering projects is listed to illustrate the wide variety of engineering objectives and associated issues. The principles of technical auditing are presented and a case example included to illustrate the required supporting information and documentation. Technical auditing can be used "before the event" to guide the modeling and design or "after the event" to check that a model or a design has indeed addressed the technical objectives and included those variables, mechanisms and parameters required to represent the rock reality. The audit trail provides transparency and traceability for modeling and design. JF - Proceedings - Symposium on Rock Mechanics AU - Hudson, J A A2 - Amadei, Bernard A2 - Kranz, Robert L.

This paper models the response of yielding pillars is using the progressive failure approach coupled with the enhanced displacement discontinuity method (EDDM). The EDDM, unlike the DDM, explicitly considers the effect of confinement. The progressive failure procedure is an iterative technique that employs a quasi-elastic approach to account for the residual strength of rock material after initial failure. The extent of pillar yielding is evaluated using the Mohr-Coulomb failure criterion. The potential benefits of using progressive failure with EDDM are demonstrated through two- and three-dimensional examples. These examples were chosen to illustrate the flexibility, robustness and power of the proposed method for simulating pillar failure on a mine-wide scale.

The mine produces coal from the Upper Hiawatha Seam of the Mesa Verde Group (Cretaceous) strata. Annual subsidence monitoring, mostly by aerial photogrammetric methods, has been conducted for the last 22 years. In 1998, detailed survey measurements of vertical and horizontal displacements over a longwall panel were conducted in order to better understand the response of the 61-m-thick (200-ft-thick) Castlegate Sandstone and to develop a failure criteria for naturally occurring rock formations. Measurements indicate magnitudes and directions of transient and permanent deformation over the panels and gateroads as a result of longwall panel retreat. Vertical subsidence magnitude ranges up to approximately 1.62 m (5.3 ft). Magnitudes of horizontal movement measured over the panel have been up to 0.19 m (0.62 ft).

The results showed that the permeability and porosity increased initially, but slowed down with continued leaching. Also, the amount of copper recovered decreased gradually. Topographic imaging of the specimens showed an increase in the number of fractures and fracture aperture as leaching progressed. These observations are attributed to dissolution of copper minerals present along the fractures first, resulting in increased porosity and permeability. This phase is followed by stable conditions due to depletion of soluble material along the fractures, and possibly, matrix flow. The field observation showed that the permeability remained constant initially, increasing dramatically after about eight months, and finally, decreasing significantly. The final decrease in permeability is attributed to precipitation of sulfates and/or migration of fines produced, clogging up the fractures.

This method has left approximately 20% of the orebody in the remaining pillars. The original design and planning for the mines did not include extensive pillar extraction. This paper summarizes the introduction of the pillar extraction and backfill techniques, which have been implemented since 1991. In conjunction with these accomplishments, much experience and confidence has been gained in the use of numerical modeling as a method of predicting pillar stability as the mining of pillars progresses. These advances have led to pillar extraction becoming a major portion of the overall production and have added to the mine life of Doe Run's eight operating mines in Missouri.

As a general rule such criteria are based on laboratory scale specimens with very little, and often no, field validation. This paper sets out to provide limited field verification of existing shear strength criteria. The paper critically reviews the Hoek-Brown criterion with particular reference to the shear strength of large rock masses. The review indicates that existing criteria have several severe limitations and are unlikely to predict rock mass behavior over a broad range of conditions. For this reason, it is important that any criterion be validated for the intended use. Several large slopes have been examined with a view to establishing field bounds on shear strength criteria for very large rock masses.

Catoosa shale and Twin Creeks siltstone were tested to represent the range of fine-grained rocks encountered in deep Gulf Coast drilling. Tests were conducted with core plugs submerged in air, water, mineral oil, and a weighted, water-based drilling fluid. The peak failure strengths measured in these tests corresponded well with strengths measured in triaxial tests at similar confining stresses. Residual stresses were measured at large strains and shown to be an inverse, non-linear function of normal stress. Very little difference in failure stress was observed in tests conducted in different fluids. Consequently, the differences in bit rate of penetration performance with different drilling fluids are probably not caused by any effect of drilling fluid environment on formation failure strength.

This algorithm uses multivariate cluster analysis to group discontinuities (joints) into sets based on orientation and spatial position (spacing) along the bore hole, and to display the data in a three dimensional stereonet. Although drift or surface exposure mapping data allows better characterization of discontinuities, bore hole data is often more readily available, because of lower costs. In addition, bore hole data may be more useful because bore holes can be drilled to the exact location where the ground needs to be characterized and bore hole data is usually available earlier in the life cycle of an engineering project.

To overcome this difficulty, the equivalent continuous model is applied instead of the joint element method. In this study, focus is placed on the mechanical parameters, normal stiffness k (sub n) and shear stiffness k (sub s) . The relationship of k (sub n) and k (sub s) (Goodman 1984) is measured in this study by constant tau /sigma loading tests. Then, the results are used to determine the material constants of the equivalent continuous model.

Metallic foil strain electrical resistance gages were used to measure tensile and compressive strains and track fracture development during loading using clear, podular, and argillaceous halite specimens. A charge-coupled device (CCD) camera was used to image fractures and measure the increase in load contact area affecting the distribution of fracture patterns. These tests have provided a better understanding of what effect microstructure, such as grain size and clay inclusions, has on fracture initiation and propagation.

The model can predict the hydro-mechanical coupling for applications such as slopes, tunnels and foundations. The basis for the mechanical part of the system is a micromechanical model for both extensile and shear crack growth. The basis for the hydraulic part of the model is the flow through rectangular tubes. The model takes into account three coupled processes: the decrease in permeability due to the squeezing of initially open cracks, the increase in permeability due to the growth of extensile cracks, and the increase in permeability due to the growth of shear cracks. Calibration studies with the model show close agreement with lab data. JF - Proceedings - Symposium on Rock Mechanics AU - Leem, J AU - Kemeny, J M A2 - Amadei, Bernard A2 - Kranz, Robert L.

The applications range from problems in tunnelling to the analysis of arch dams. Three case studies will be examined with respect to accuracy and efficiency. Efficiency is measured as time required to generate the mesh, computer time spent in the analysis and time spent for post-processing results. If available, comparison will be made with meshes involving finite elements only. The conclusion of the paper is that a coupled analysis offers a considerable reduction in time spent in the pre-processing/analysis/post-processing but does not result in any appreciable loss of accuracy.

This retrospective view is written to identify strong currents in a large river of progress rather than to develop a comprehensive state of the art, which can be found in my 1996 book, Construction Vibrations. Specific case studies set the stage for the following discussion of trends. These trends in turn provide the background for a possible "out of the box" approach to increase understanding by the lay public of the low impact of vibration at the current control limits.

The program can give the distribution of slope angles integrated over all the profiles. The distribution of maximum angles for various base lengths of asperities and the corresponding dilatancy for these maximum angularities were computed using Rengers equation to obtain its behavior in relation with asperities base length (or shear displacement) under null normal stress. An experimental verification of this analog simulation was performed through a direct shear test program on a well-studied replica of a natural joint under null normal stress (push-test) for four different shear directions. The dilatancy characteristic results obtained from this testing program compared to those from the analog simulation show a relatively good agreement and permits an evaluation of the directional anisotropy of dilatancy.

First, a laboratory shear test method is presented in which shear testing is performed applying normal stress level of field condition to establish the value of mechanical properties including normal and shear stiffness of natural rock joints. In addition, a field investigation method is also proposed to identify the joint geometry in a rock mass. Finally, these methods are applied to determine the input data for DEM (distinct element method) analysis while carrying out the stability analysis of a jointed rock slope situated in Omaru river dam site, Kyushu island, Japan. The results of the stability analysis convincingly reveal the positive significance of the proposed methods predicting the plane failure along a geological contact as a response to the excavation of the slope for a dam foundation.

Its documented magmatic expression in the southeastern U. S. is a dispersed assortment of plutons, predominantly I- and S-type granitoids, emplaced in terranes north of the proposed suture. Granitic rocks from two drillholes located south of the suture in the northern Suwannee terrane, however, have recently been found to have been emplaced during the Alleghanian orogenic event. Crystallization ages determined via SHRIMP U-Pb zircon geochronology are 293+ or -2 Ma and 294+ or -4 Ma (2-sigma errors) for samples from Calhoun Co., Florida, and Seminole Co. Georgia, respectively. Inherited zircons with (super 207) Pb/ (super 206) Pb ages of ca. 550 Ma and ca. 1 Ga were present in the Seminole Co. sample, consistent with a South American provenance (Brasiliano, and Orinoquian or Sunsas-Rondonian, respectively) for this segment of Suwannee terrane lithosphere. Initial epsilon Nd values are -0.1 and -1.0 for Calhoun Co. samples and +1.0 and +1.6 for Seminole Co. samples. Depleted mantle Nd model ages are 1010 and 1107 Ma for Calhoun Co. and 722 and 747 Ma for Seminole Co. rocks. These Nd data indicate that slightly younger sources, or a greater proportion of an asthenospheric mantle component was involved in the petrogenesis of the Seminole Co. granite. Although numerous Alleghanian plutons have been documented on the Laurentian side of the suture, these granites are the only known expressions of Alleghanian magmatism on the Gondwanan plate. The presence of magmatism on both plates supports tectonic models of the Alleghanian event involving an oblique collision between Laurentia and Gondwana. Trace element data for the Suwannee terrane granites place them in the within-plate field on tectonic discrimination diagrams.

While virtually all park areas contain geologic resources, approximately 83 park areas were set aside because of their geologic significance. In 1998, more than 287 million people visited national parks and most visitors were exposed to interpretive services provided by the National Park Service. National park sites are natural laboratories where the interrelationships between geologic, biologic, and human systems can be observed firsthand by a wide cross section of people. The National Park Service uses interpretation to help visitors make intellectual and emotional connections with the meanings and values inherent in park resources. Promoting understanding of earth systems relationships is critical for park management and stewardship. The National Park Service is exploring innovative ways to interpret earth systems relationships throughout the park system, including efforts at both natural and cultural parks. Examples of earth systems interpretation occurring at natural parks include an exhibit on the relationship between bedrock geology and rare and endangered plants at Capitol Reef National Park, and programs about how the eruption of Sunset Crater Volcano influenced the Ancestral Puebloan people living in the vicinity. Relationships between people and natural systems are interpreted at Mesa Verde National Park, Harpers Ferry National Historical Park, and other cultural parks. Interpretation of earth systems relationships can occur both in-park and off-site through the use of the world wide web, classroom curricula, and other media. Effective earth systems interpretation is important because it tells the whole park story. Human history is incomplete without exploring the influence that natural resources had on human affairs, and biologic systems are dependent on geologic relationships. National parks also provide other educators and researchers opportunities to interpret earth systems. Together, National Park Service personnel and others can use parks to promote an understanding of the importance of protecting park resources and an understanding of the value that national parks have as places that help us understand the interrelationships of all the systems and processes interacting at the earth's surface.

Assuming the form of the vertical turbulent intensities and dilute concentrations of sediment, one can solve the equations analytically and compare them with experimental data. No empirical coefficients in the model are tuned to match individual experiments, for which the experimental data cover a large range of particle sizes and densities. The models are shown to accurately predict two experimentally observed but theoretically unexplained phenomena: the increased diffusive flux of large particles, and the measurable velocity lag of particles. The increased diffusion of large particles is shown to originate from the added diffusive nature of the sediment's Reynolds stresses. The horizontal velocity lag of particles is due to an induced velocity, termed the drift velocity, resulting from the correlation of particle concentration with areas of low horizontal velocity fluid.

We provide the missing original citations along with some clarifications. We focus especially on the age of distinctive Fort Rock and Multiple Warp-style sandals, for which we provide additional previously unreported (super 14) C ages. Direct dates on fibers from Fort Rock sandals from 3 different sites range in age from 10,500 cal BP to about 9200 cal BP. Contextual evidence suggests that Multiple Warp sandals may date as early as 6600 cal BP, but the few directly dated specimens are less than 1000 yr old.

GIS based precision surveying and photogrammetry are used to facilitate construction of a comprehensive database of information gathered on all aspects of the study and provide a spatial framework for data analysis. Efforts have thus far concentrated on an exposed area of approximately 1600 square meters. Techniques developed from the study of this surface will then be applied to outlying areas of exposure and to tracksite localities elsewhere. A number of functions are well suited for the use of a Geodimeter surveying instrument. This includes establishment of a grid on the surface, supplemental measurement of the track characteristics and three-dimensional location coordinates of targets used in photogrammetric image rectification. The instrument is capable of storing up to 20,000 coordinates and associated attributes in an on-board computer. Data acquisition times are minimal and the format is easily converted to meaningful GIS features in the field to provide up to the minute visual presentation of the data. Extensive photographic documentation and analysis of the track-bearing layer is being completed for the primary area of study. Close range photogrammetry (174 cm above the track surface) is used to document the track surface on a meter by meter basis. These photographs will be georeferenced using the survey data and compiled into an image mosaic that can be transformed into a 3-dimensional representation of the track surface. Various scales of standard format aerial photography, as well as 35 mm photos taken from a Low Altitude Remote Controlled (LARC) plane and from an Ultralight aircraft will be georeferenced to the three-dimensional coordinates and used in the spatial analysis.

S. In September 1997, alluvial-fan flooding occurred on Tiger Wash in west-central Arizona as a result of heavy rainfall associated with dissipating tropical storm Nora. We analyzed the distributary part of the Tiger Wash system to evaluate the efficacy of surficial geologic mapping in delineating alluvial fan flood hazard areas. We also collected data to characterize the nature of flood flows on alluvial fans in this region. Investigations consisted of (1) description and mapping of surficial geologic deposits using pre-flood aerial photos; (2) mapping and characterization of inundation that occurred during the 1997 flood; (3) comparison of pre-and post-flood aerial photos to document channel changes; and (4) hydraulic reconstructions of peak discharges in channels at several key localities. Throughout the tributary drainage network and into the upper part of the distributary system, flood flow was conveyed in channels and relatively narrow overbank areas that are inset below adjacent middle Pleistocene to middle Holocene fans and terraces. In the distributary system, flow was partitioned unevenly between major east and west branches; about 75 percent of the peak flow went down the west branch. Broad sheetflood inundation indicative of alluvial fan flooding occurred farther downstream in flow expansions nested in the larger distributary system. Several large new channels developed and substantial channel modification occurred in the west branch system. At least 95 percent of the 1997 flood inundation occurred in areas that were covered by late Holocene deposits prior to the flood. Thus, surficial geologic mapping is an excellent predictor of the extent of flood-prone areas on this piedmont.

Control of flood flows, and water delivery by canal, rather than down-river, combined with in-channel sand and gravel mining have resulted in a poorly defined channel that links a series of valley floor ponds that are bordered by a narrow strip of riparian vegetation in the terrace-confined reach between Friant Dam (RK 400) and Gravelly Ford (RK 344). On the active alluvial fan of the San Joaquin River between Gravelly Ford and Mendota Dam (RK 308), the meandering channel has been leveed, and the bulk of the flood flows are diverted into the Chowchilla Bypass channel. Except during floods, the channel of the San Joaquin River is dry and supports almost no riparian vegetation. Water imported from the Delta is routed down the meandering channel as far as Sack Dam (RK 273) where it supports a narrow riparian community. The formerly multiple-channel, anabranching reach between Sack Dam and the Merced River (RK 177) has been converted into a single channel bordered by intensive agriculture. The channel conveys primarily poor quality agricultural tailwater except under flood conditions when Mariposa and Eastside Bypass flows are returned to the river, and supports limited riparian vegetation with little or no regeneration. The anthropogenic disturbances to the river system and the resulting morphological and hydrological changes have resulted in the extirpation of anadromous Spring and Fall-run chinook salmon, as well as steelhead.

Often databases were created to store and manage this information. The Environmental Protection Agency, Office of Radiation and Indoor Air, and the National Park Service, Geologic Resources Division, are developing a pilot project to locate and evaluate these abandoned mine lands-related databases. This "database of databases" named the DATAMINER will list, categorize, and compare databases that can be used for the evaluation, prioritization, characterization, and reclamation of abandoned mine lands. Through this project, the Environmental Protection Agency will avoid duplication of efforts, conserve resources, assist decision makers in a better understanding of what information is available on abandoned mines sites, and protect public health.

Seismic loads are very high and there is a large population at risk downstream of the dam in a narrow, confined canyon. The dam was constructed in 1937 and raised 30 feet in 1957. Foundation investigations and analyses performed in 1990 resulted in a decision to construct a stability berm at the downstream toe to improve the dynamic stability. A dynamic stability analysis was not performed. Decisions concerning the potential for foundation liquefaction were made by estimating the ability of the complex sandy gravel foundation to dissipate pore pressure during an earthquake. The foundation depositional environment is very complex and includes lacustrine deposits from prehistoric Lake Bonneville and smaller lakes, delta and fan deposits from side channels, various alluvial deposits from the Ogden River, and various deposits from the steep valley walls due to mass wasting. Field investigations included Standard Penetration Testing, borehole shear wave velocity testing, and sampling. Drilling was difficult and sample recovery was overall very poor. In 1998, Reclamation completed a probabilistic risk analysis for Pineview Dam, which included seismic, static, and hydrologic loading. The results of the risk analysis indicated that additional analysis and data are needed to better understand the potential for foundation deformation and embankment cracking. Because of the very high seismic loading conditions and the large population at risk, a very high level of confidence is needed to meet public risk guidelines when determining foundation performance. The difficulties of reaching this high level of confidence through geologic investigations and analysis are presented along with a summary of the various analytical tools utilized. The difficulties of drilling, sampling, measuring, and modeling in this complex sandy gravel foundation are also discussed along with the 1999 exploration program which is currently underway.

Pit water quality had been alkaline with low metals and moderate dissolved solids content for at least 15 years. A decline in water quality occurred with a decrease in pH, and increase in dissolved aluminum, manganese and sulfate. The recharge area for the flooded pit included a coal refuse pile, flooded underground mine works, flyash pile, surface minespoil and a sediment pond. A set of water quality samples were analyzed for mine drainage parameters, major dissolved constituents and some trace metals. These data were inverse modeled using the flooded pit water as the end product. Mixing of several possible sources and single source recharge scenarios were run along the inferred ground water flow path. Mixing of coal refuse pile leachate with leakage from the sediment pond or minespoil provided acceptable characterization as the principal sources controlling pit water chemistry. These results were consistent with the ground water flow path interpreted from water level measurements in wells, structure, air photos and mining history. The dominant rock-water interactions modeled were dissolution of carbonate minerals and stored sulfate salts. Simple binary mixing was not adequate to describe the reaction path and resultant water chemistry. Geochemical models were useful for assessing mine drainage sources, and can be included as one of a collection of investigative tools.

Public pressure and resulting policy changes have become a driving force in the reclamation of these sites. Two of the key reclamation issues for these sites is the occurrence of acid forming materials (AFMs) in mine soils, and acid mine drainage (AMD) issuing from mine adits. An AMD treatment system design project for the Forest Queen mine in Colorado's San Juan mountains raised the need for a simple, useable method for analysis of mine land soils, both for suitability as a construction material, and to determine the AFM content and potential for acid release. We have developed a simple, stepwise, go-no go test for the analysis of mine soils. Samples were collected from a variety of sites in the Silverton, CO area, and subjected to three tiers of tests including: paste pH, Eh, and 10% HCl fizz test; then total digestion in HNO (sub 3) /HCl, neutralization potential, exposure to meteoric water, and toxicity content leaching procedure (TCLP). All elemental analyses were performed with an inductively-coupled plasma (ICP) spectrometer. Elimination of samples via the first two testing tiers left two remaining samples, which were subsequently subjected to column and sequential batch tests, with further elemental analysis by ICP. Based on these tests, one sample was chosen for suitability as a construction material for the Forest Queen treatment system basins. Further simplification, and testing on two pairs of independent soil samples, has resulted in a final analytical method suitable for general use.

Calcium amendments and sawmill wood wastes were applied to the regraded spoils to enhance water infiltration, displacement of Na on the clay spoil, and leaching of the displaced Na and other soluble salts. Revegetation of these lands was generally successful, but after several years small areas (0.1-0.2 ha) began to show signs of vegetation stress or death. The purpose of this research was to determine the cause of vegetation die-back and to prescribe corrective treatment options. A randomized block design was imposed on study areas near Upton, Colony, and Greybull, Wyoming to characterize spoil chemical properties of "good," "moderate," and "dead" vegetation zones, which were subjectively delineated by visual vegetation cover and density differences. Spoil analyses indicated exchangeable-sodium (Na) concentrations were high and the "dead" vegetation zones exhibited exchangeable-sodium-percentages (ESP) above 50%, while surrounding "good" vegetation zones exhibited ESP values <10%. This coupled with low soluble-Na concentrations (<2 cmol/kg) suggests insufficient calcium (Ca) amendments were initially applied to ameliorate the sodic conditions of the spoil. The sampling design used to determine Ca amendment rates, which consisted of a composite of 5 spoil cores taken from each 0.8 ha area, was apparently insufficient to account for the highly heterogeneous spoil material that occurred throughout these abandoned bentonite reclamation sites. To revegetate these small degraded sites, additional Ca amendment would be necessary and reseeding would be required. However, we recommend further monitoring of the affected sites to determine if unfavorable conditions continue to degrade the reclaimed landscape before any attempt is made to rehabilitate the affected sites. If the degraded sites are stable, further Remediation efforts are not warranted because small areas of little or no vegetation are common on native landscapes of these areas.

Because the pH of the mine drainage averages between 3 and 5 and the iron concentration averages 18 mg/L, it was thought that the wetland would naturally treat the water. One of the important contaminants to be treated is zinc which averages 0.60 mg/L in the adit water, while the aquatic criterion is 0.50 mg/L. In the study that was undertaken to determine whether metal removal was occurring, considerable effort was made to link the water and soil chemistry with the wetland hydrology. There are at least two water systems influencing the wetland: the mine drainage across the surface and ground water from the adjacent slope that typically flows under the wetland. These two are, for the most part, separated form each other by a layer of peat that is of low hydraulic conductivity and is over 1.8 meters deep in places. Because of the separated hydrologic systems, the Fe and Al is removed from the adit effluent when it flows across the surface. However, because the PH does not exceed 6.5 for the most part, Zn is not removed.

Surface affects compared to mine maps indicated the subsidence to be mine related. However, two coal seams had been worked under this area. The upper seam, the American seam, ranged from 250 to 280 feet beneath the surface in the area in question. It was mined-out before 1955 by room-and-pillar method leaving in place narrow-long pillars to support the overburden strata, and abandoned in 1955. The lower seam, the Mary Lee seam, ranged from 650 to 700 feet beneath the surface. The Mary Lee seam had been abandoned in 1966 and subsequently became flooded. The dewatering of the Mary Lee seam workings in 1985 caused the submerged pillars to be exposed to the atmosphere. Due to multiple seam mining and the fact that workings had been inundated then dewatered, a subsurface investigation ensued to determine the sequence and ultimate cause of surface subsidence. Core sample tests with fracture analysis in conjunction with "down-the -hole" TV camera inspections provided necessary information to determine that the subsidence started in the lower seam and progressed through the upper coal seam to the surface. Evidence from the investigation program established that dewatering of the lower seam workings caused the marginally stable support pillars and the roof to collapse. This failure triggered additional subsidence in the upper seam which broadened the area of influence at the surface.

The construction of an anaerobic passive treatment system requires a mixture of local materials with the objective of producing a system that allows adequate water flow while supporting the growth of sulfate-reducing bacteria. These bacteria have the effect of reducing the oxidizing potential in the system causing many sulfide-forming metals in solution to precipitate. The focus of these experiments was the study of chemical characteristics of materials, individually and in mixtures, with the purpose of determining which would be best suited for incorporation into a treatment system. The materials of interest were manure (fresh and aged), alfalfa, limestone, and sawdust, which were all collected in close proximity to the construction site of the proposed treatment system. A variety of chemical and physical hypotheses were formulated prior to performing simple chemical characterization and anaerobic treatment tests. The hypotheses relating to the chemical nature of the single materials were carbon to nitrogen ratio, availability of low molecular weight organic acids, number of adsorption sites, and organic carbon content. In addition, hypotheses concerning the performance of mixtures were evaluated by looking at the relative amount of bacterial growth (and metal removal) seen in each mixture over a 4-week period. The results of the laboratory experiments confirmed the hypotheses, and demonstrated that in the mixtures, the anaerobic bacteria flourish when alfalfa is present, up to a point. The best mixture that allowed proliferation of bacteria while also removing metals consisted of 50% limestone, 25% aged manure, 15% sawdust, and 10% alfalfa (% by weight).

S. Geological Survey collaboration is producing a new, digital geologic map database for Great Smoky Mountains National Park (GSMNP). The database is part of a Geographic Information System that will incorporate geology, vegetation, soils, topography, cultural disturbance, transportation, and hydrography data as part of the recently initiated All Taxa Biodiversity Inventory (ATBI) of the Park. The GSMNP contains at least 13 distinctive rock types in 60 formations, about 10 distinctive surficial deposit types, numerous soil classes, more than 1,500 m of steep mountainous relief, and heavy rainfall. This ecosystem supports over 60 different natural habitat types and a multitude of gradient-specific communities. The interrelationships of geology and biology include: (1) sulfide-rich slaty rocks limit the distribution of fish and invertebrate species but support some taxa that appear to have speciated on this rock type; (2) restricted areas of limestone limit occurrences of terrestrial and aquatic mollusks; (3) soils on deeply weathered granitic gneiss support Purple spurge, a former federal candidate for endangered species; (4) boulder fields of quartzite and sandstone control distributions of rare, uncommon, and endangered plants such as Yellow wood and Bunchflower; and (5) mafic and ultramafic igneous rocks and associated soils support rare plant communities, which in turn are habitat to differing suites of fungal, protist, and animal taxa. The new maps and database are important tools to guide soil scientists and biologists involved with the ATBI to areas of the Park potentially harboring unique, rare, and possible endangered species.

Some zones and subzones within the tuffs contain few (or no) lithophysae; in other zones, centimeter- to decimeter-sized lithophysae occur locally in unimodal, bimodal, or seriate distributions. Lithophysae shapes vary from simple to compound (i.e. coalesced cavities), and spherical to cuspate (i.e. partially deflated cavities). Near boundaries between lithophysal and nonlithophysal zones, lithophysae aspect ratios can be as large as 20, elsewhere, they may be as small as 1 to 2, representing fully inflated cavities. Two types of cooling fractures occur in lithophysal and nonlithophysal zones and both can have vapor-phase mineral coatings. Type 1 fractures are typically long (up to 50 m), planar, and smooth, many with light-gray rinds and some have tubular structures. Tubular structures are circular to rectangular in cross section, and in the fracture plane, form parallel or anastomosing sets oriented at low angles to foliation. Type 2 fractures lack rinds and tubular structures, and are not as long, planar, or smooth as Type 1 fractures. More than 90 percent of both units are composed of densely welded, mostly crystallized tuff. Groundmass-crystallization color and texture near lithophysal-cavity rims and fracture rinds, and locally in broad, sharply bounded areas differs from crystallization color and texture occurring away from these features. Vapor-phase corrosion of glass occurred commonly in the upper parts of densely welded rocks, and locally in the top and bottom of moderately welded rocks. Vapor-phase minerals formed where corrosion occurred, in lithophysal cavities, and along many fractures. These various features constrain a sequential development of the following processes. Welding began shortly after (or during) deposition, resulting in densely welded glass throughout the deposit. During welding, intergranular vapor was transferred by flow through the matrix or along early formed (type 1) fractures. Lithophysal cavities developed where vapor attained super-lithostatic pressure. Early formed (type 1) fractures developed within the vitric phase. Tubular structures result from: 1) tension fractures along fracture faces as the rock stretched during growth of lithophysae, or 2) vapor etching during transport through the fractures. The glass matrix crystallized differently, depending on the presence or absence of vapor. Vapor-phase corrosion occurred during the period of peak temperatures, and mineralization occurred primarily during the cooling phase. Late formed (type 2) fractures formed after crystallization of the groundmass.

One narrow, incised channel exposes as much as 20 m of fine sand and silt and about 50 layers that contain charcoal. Charcoal is concentrated at bedding breaks but also occurs within beds and paleosols. Eight AMS (super 14) C dates were determined for charcoal within beds or on bedding breaks, ranging from 1,280+ or -50 to 9,190+ or -50 BP (WW-1733-1736, 2071-2074). The undated lowest part of the sediments is probably late Pleistocene as a mastodon tooth was found in the streambed in the 1960s. Deposition rates are 0.6-1.3 mm/yr. The sediment source is mainly the blanket of upland eolian fine sand and silt, derived from weathered Jurassic Entrada and Wingate Sandstones. We conclude that wildfire destruction of vegetation and soils in the pinon-juniper uplands allowed rapid erosion of eolian materials that poured into the canyons where it was deposited as fine-grained alluvium. This charcoal record has the potential to increase our understanding of Holocene natural fire frequency, rates of upland erosion and alluviation, and history of debris-flow and flash-flood hazards. Fire-scars in uplands pinon-juniper forests provide only a few hundred years of fire history, but numerous pack rat middens under rock overhangs probably contain palynological records that provide vegetation records of climatic changes far into the Holocene, augmenting the use of the sedimentation and fire record. Extensive research is needed to define natural fire regimes prior to European arrival. Past sedimentation, fire, and climatic histories can be used to integrate multidisciplinary aspects of this dynamic ecosystem. Such knowledge can be used to create viable fire management plans and to maintain sustainable ecosystems.

The coal fires have collapsed and baked the overlying strata to produce clinker--a suite of hard, reddish to black, highly fractured, thermally metamorphosed rocks. This clinker, as thick as 200 feet, shapes and colors much of the landscape of the basin. Being more erosion resistant than unbaked strata, clinker persists during downcutting to form caprock on hills and buttes. The broken topography of clinker hills and escarpments has created a unique set of ecologic niches that protect plants and animals from the weather extremes of the open plains. Well drained soils and water at depth encourage species such as ponderosa pine and skunkbush sumac to colonize areas of clinker. High permeability and infiltration rates enable the 1600 square miles of clinker in the basin to store large amounts of water from rainfall and snowmelt, and protect it from evaporation. These unconfined clinker aquifers have very high transmissivity and storativity values. Peak flows in clinker-dominated drainages are attenuated, and water is discharged gradually to streams during periods of lower flow. Springs which emerge from the base of clinker form the headwaters of several perennial streams and provide wetland habitat for many species. In the Rochelle Hills of Wyoming, groundwater from clinker recharges coal, overburden, and spoil aquifers downdip to the west. Some mines encounter inflow from large saturated clinker bodies updip, where water is dammed against the face of the less permeable coal. Groundwater quality in clinker varies widely; quality appears better in well-drained areas where soluble ash at the base of the clinker has dissolved away, and poorer where water has ponded along a coal contact.

This metamorphosed rock, known as clinker, presently covers about 1600 mi (super 2) in the PRB-1100 mi (super 2) in Montana and 500 mi (super 2) in Wyoming. Much additional clinker has been eroded away. A wide variety of clinker rock types is produced, depending on lithology of the parent rock, temperature and duration of heating, and degree of oxidation. Clinker ranges from slightly yellowed and hardened strata through brick-like fired and sintered rock to black vesicular paralava. Coal bed fires are ignited primarily by range fires and spontaneous combustion on outcrops that are above water table. During regional lowering of the land surface by erosion, the water table also drops, making progressively lower coal susceptible to burning. Episodes of burning have occurred over the past several million years as erosion has exposed coal through downcutting and hillslope retreat. Being more erosion-resistant than unbaked bedrock, clinker forms caprock throughout the basin. The oldest clinker in place generally caps the highest buttes and plateaus. Detrital zircon fission-track ages as great as 2.8+ or -0.6 my from clinker in place, and as great as 4.0+ or -0.7 my from a clinker boulder in a stream terrace gravel, provide a tool to help decipher late Tertiary and Quaternary rates of downcutting by streams in the PRB. The ages indicate that much of the downcutting in the present day Tongue River valley occurred during Quaternary time.

The area covered extends from the High Plains geomorphic province westward to include the Rocky Mountains and the Great Basin. The subject is presented in two parts, of which this is the first. This first part traces the history of geological exploration of the High Plains from its inception in the 1860's to the present. Historically, the emphasis of study has been in the specialized field of vertebrate (especially mammalian) paleontology. It was in the classical area of western Nebraska and adjoining regions that much of the modem chronostratigraphic classification of the Middle Tertiary, the North American Land Mammal Ages, (NALMA) was developed and extended elsewhere. The relationship of the NALMA to the rock stratigraphic section of this province is described from an historical perspective and is reviewed critically in terms of proper application of widely accepted rules of stratigraphic nomenclature. Much of the lithostratigraphic terminology that has been used in this province appears flawed in a technical nomenclature sense. These apparent flaws are treated at length and remedies are suggested. As a case in point, the name Ogallala Formation (or Group) lacks validity and it is recommended that it be replaced with its senior synonym Ash Hollow Formation. There is no acceptable scientific defense for retaining current usage. The mid-Tertiary lithostratigraphic units lend themselves to a tripartite grouping: These consist of. (1) a lower unit characterized by several formations of relatively broad areal extent which consist of loessic deposits having a very high volcaniclastic composition and includes the White River and Arikaree Groups; (2) a middle grouping of formations (Runningwater, Box Butte, Sheep Creek, Olcott, Sand Canyon and Valentine) which occur as a complex of elongate, narrow stream channel deposits which have only a minor tuffaceous content; and (3) a thin but very extensive deposit of typically sandy and gravelly fluvial beds of the Ash Hollow Formation.

In this paper, we develop a method to calculate the redistributed stresses around a depleted, heterogeneous reservoir with non-uniform pressure distribution. Using this method, we analyze the stability of nearby faults and show that different reservoir depletion strategies can affect the fault stability differently. The reservoir is modeled as a thin poroelastic inclusion in an elastic matrix while the fault gouge obeys Mohr-Coulomb failure criterion. The developed method allows considering the reservoirs and faults to be of arbitrary shapes and material properties while the pressure inside the reservoir does not have to be uniform. After the fault is reactivated, it is modeled as a shear (mode II) fracture. Displacement discontinuity between the sides of this fracture gives an estimate of the fault slip magnitude.

Project architects developed structural designs consisting of 30-by 90-m pillars in a seven-entry waste panel system using 10-m-wide rooms. It was assumed that the pillars would experience creep deformation and enclose the waste packages gradually without significant fracturing. However, there has been a significant amount of fracturing in the mine roof and floor, and approximately 6 years after excavation, the pillars have begun to deviate from steady-state creep deformation. Based on a review of deformation data from 121 instrument clusters, multiple regression analyses, and observations of ground behavior since 1993, the authors identified factors influencing structural stability. These factors are (1) entry geometry, (2) extraction ratio within panels and in-panel pillar behavior, (3) sequence of excavation and load transfer between adjacent panels, (4) support density, and (5) ae of excavations.

Field drilling experiments were carried out on two different rock formations, namely, Southwick Sandstone and Chicopee Shale. Regular carbide rotary drill bits with three different conditions (new, worn and bearing failure) were used, providing several well-defined drilling situations. Acoustic emission (AE) were monitored during the drilling and then characterized. Analysis on the AE signals showed that significant differences in AE properties can be found among different drilling situations such as: new bit, worn bit, etc.; and that these differences may be identified by pattern recognition techniques.

The studies to date have concentrated on the fluid transfer processes, the containment properties of the media and the properties of the Excavation Disturbed Zone (EDZ) related to the gallery excavation. The Tournemire site is characterized by a sub-horizontal indurated argillaceous layer, with a 250 m thickness of Jurassic argillites and marls. This series is located between two limestone aquifers. The Tournemire site has been affected by several past tectonic events, the Pyrenean compressional event being the predominant event. Several faults and fractures affect this indurated argillaceous media and this structural pattern allows us to analyze the fluid transfer along these discontinuities. A 2-km-long, 100 year old, railway tunnel gives access to this argillaceous layer. Recently (1996) two galleries 30 meters long have been excavated perpendicular to and in the middle of the old tunnel. This geotechnical context allows us to compare the EDZ in a century old tunnel (6 m height) with the EDZ in the recently excavated galleries (3, 7 m height). This paper presents the geological and tectonic setting of the Tournemire site. The characteristics of the argillaceous media are described in detail. The fracturation associated with the tunnel and the gallery excavations are studied from a structural point of view. Finally, results from initial geophysical investigations are presented. These were carried out to investigate the feasibility of using seismic methods to study the properties and behaviour of these argillaceous rocks. Experiments carried out both on samples in the laboratory and in situ (acoustic emission monitoring and characterization of the EDZ) are described.

A 40 m long tunnel was excavated in the direction of the maximum in situ stress, with approximate dimensions of 4.4 m horizontally and 3.5 m vertically. These two dimensions were chosen to reduce the magnitude of the high stress concentrations, which occur in the roof and floor of sub-horizontal tunnels at the URL. Two bulkheads have been constructed and keyed into the tunnel to create a chamber in granite, which can be pressurised to ambient pore pressure (4 MPa). This paper presents the results of the AE/MS monitoring of the excavation phase of the TSX and the velocity interferometry measurements taken to monitor the time-dependent development of the excavation disturbance zone (EDZ). The results support stress modelling predictions and show that induced microcracking is limited to within a 0-2 m shell around the excavations.

The proposed LEFM solution uses Finite Element Method (FEM) and covers cylinders containing a finite number of radial cracks ranging between 2 and 500 and analytical solution for infinite number of internal radial cracks. When the number of cracks exceeds about 100, the LEFM solution shows that the results differ very little from the previously proposed quasi-static solution, which assumed an infinite number of internal radial cracks in the cylinder. An analytical expression is found for the stress intensity factor for mode I K (sub I) , the strain energy release rate G and the strain energy U, using the infinite approximation for the stress and strain. For a number of cracks over 100 the analytical approximation for the K (sub I) , G and U gives an excellent results. The results for the bursting pressure are found to agree favorably with those obtained in three independent experimental investigations.

Data analysis of observed pressure buildups in injection and monitoring wells indicates non-linear flow behavior including pore-fluid redistribution and inertial flow, as well as the presence of constant pressure boundaries. A method for visualization of cross-well pressure connectivity was developed which reveals good connection within individual lava-flow units, but poor pressure response across rubble zones separating lava-flow units.

These fractured rocks form an important regional aquifer that consists of gradational sequences of shale, siltstone, and sandstone, with fluid transport occurring primarily in fractures. An extensive suite of geophysical logs was obtained in seven wells located at the borough of Lansdale, PA in order to characterize the areal hydrogeologic system. Analyses of these data indicate that the aquifer can be separated into two distinct structural domains which may, in turn, reflect different mechanical responses to basin extension: (1) In the shallow zone above 125 m, the dominant fracture population consists of gently dipping bedding-plane partings that strike N46 degrees E and dip to the NW at about 11 degrees . Fluid flow is concentrated within the upper 80 m and transmissivities rapidly diminish in magnitude with depth. (2) The zone below 125 m marks the appearance of numerous steeply dipping fractures that are orthogonal to the bedding plane features, striking subparallel at N227 degrees E but dipping sharply to the SE at 77 degrees . This secondary set of fractures is associated with a reasonably thick ( nearly equal 60 m) high-resistivity, low-transmissivity sandstone/siltstone unit that is abruptly terminated by a thin shale bed at a depth of 190 m. This lower contact effectively delineates the aquifer's vertical extent and the observed lack of hydraulic productivity with increasing depth may be associated with the gradational transition into the Lockatong Formation.

The paper describes the advantages of the stress measurement and calculation methods used for the project. The modified doorstopper technique was found to be well suited to obtain accurate results with a minimum of unverified hypotheses at a relatively low cost. A total of ten measurements in two pillars were done in less than three days and led to results that are compared to stresses obtained from a 3D numerical analysis using the MAP3D boundary element code.

One polyurethane-based, spray-on rock lining material, designated Mineguard (super TM) , has been developed and tested primarily for use in underground hard rock mines for provision of rapidly-deployable area support coverage. Information is presented which summarizes assessment trials of the pre-and post-yield characteristics of rock and concrete materials subjected to large deformations when tested uncoated and coated using varying layer thicknesses of Mineguard (super TM) . Tests were conducted for the purpose of assessing the capabilities of thin support liners to enhance the ultimate strength of rock materials, to stabilize uncontrolled, post-yield deformation behaviour and to enhance strain energy storage capacities of failing rock mass structures. In these laboratory trials, Mineguard (super TM) surface coatings, at thicknesses of 1 to 3 mm, have been shown to beneficially enhance rock strength and other physical properties in medium to strong rock materials. Additional information, obtained from selected mine sites, is presented to validate the significant potential that such surface reinforcement agents have shown in terms of ground support capability. Experience gained by mine operators who are currently investigating the high speed application of Mineguard (super TM) coatings, and comparison of wide-ranging laboratory response tests, indicate that this or other forms of flexible, spray-on, membrane support coverings may be able to add to or replace components of current support technologies that are required for mining safely in hard rock environments.

In the 3-dimensionnal code, FLAC (super 3D) , we have implemented an anisotropic damage model. Triaxial compression tests provide a verification of the implementation with a good agreement between experiments and predictions. The applicability of the implemented model to predict damaged zone around a keyed tunnel of AECL's Mine by experience is examined. Results indicate that a square key is best to interrupt the continuity of damage zones around the keyed tunnel than the triangular or trapezoidal keys.

It is shown that the slip relaxation parameter must be scaled in proportion to the crack length if the relaxation time function is to be self-similar for all element sizes. Equivalence between the assumed slip rate law, in which the slip rate is proportional to the driving shear stress, and an exponential decay of cohesion is shown to be possible for particular choices of the loading stress. Numerical experiments of the dead weight loading of a random assembly of cracks are described to illustrate the behaviour of the model. It is found that the time series of the energy release and the length of active fractures are highly nonlinear. Attempts to identify precursory information to estimate the time to failure from the cumulative energy release rate series proved to be unsuccessful. In particular, no evidence could be found for any form of organized oscillatory behaviour in the time series prior to the time of failure.

The model includes gradual strength degradation and subcritical crack growth, together with development of process zones, strain localization and brittle failure. Prior to onset of damage, the calculated stress field around the pressurized cracks is the same as that produced by linear-elastic models. After the onset of damage, localized damage zones spread out around the crack planes, and their shape is sensitive to the state of stress. The model reproduces shapes of damage lobes and geometries of crack connections that are commonly observed around en-echelon dyke segments in sandstone. Thus, the distributed damage and the crack paths may help to better estimate the state of stress acting during growth of pressurized cracks (dykes). The close kinship between dykes and artificial hydrofracturing provides an economic incentive to incorporate our results in hydraulic fracturing analyses.

Two key rock mechanics issues that have been studied are the development of near-field excavation damage and the stability of underground excavations in granite under various boundary conditions. This paper presents an overview of four of these in situ experiments and highlights the main findings in terms of rock mechanics considerations for nuclear waste disposal.

Growth of the fracture is driven by injection of an incompressible Newtonian fluid at the center of the fracture, at a flow rate varying according to a power law of time (which includes the practically important case of a constant injection rate). The solution is restricted to the so-called viscosity-dominated regime where it can be assumed that the rock has zero toughness. In this regime, the fracture tip is characterized by a singularity which is weaker than the classical square root singularity of linear elastic fracture mechanics. The paper describes the construction of a semi-analytical similarity solution, which incorporates the known singularity of the fluid pressure at the center of the fracture and at the tip and which is based on series expansions of the fracture opening and fluid pressure in terms of Jacobi polynomials. It is shown that very few terms in the expansions are needed to capture the solution accurately.

The gabion concept has been used for more than a century in numerous erosion control and bank protection projects. These flexible, environmentally sound and economical elements can also be used in small-scale rock slope stabilization projects where more invasive methods are either impractical or cost prohibitive.

Not only has this technology allowed direct measurement of hydraulic fracture growth, it can also provide the necessary data to "calibrate" fracture growth models. Downhole tilt fracture mapping involves deploying wireline-conveyed tiltmeter arrays in offset wellbores to measure hydraulic fracture-induced deformation versus time. This technology has been employed to map over 100 fracture treatments in the last eighteen months, resulting in significant economic benefits. One example is more efficient zonal coverage by reduction/enlargement or early termination of propped fracture treatments (guided by real-time analysis). Although downhole tiltmeter fracture mapping has only been implemented in a few fields so far, it has for the first time allowed the gathering of statistically significant data sets on how hydraulic fractures actually do grow.

A weak azimuthal anisotropy was observed both in the hydrostatic and in the triaxial stress region. However, the results showed that the orientation of the principal strain directions shifted from the hydrostatic region to the triaxial region. Two different mechanisms relating to closing of microcracks and shear crack sliding might explain this observation. Another shift in the orientation of the principal strain directions was observed after peak stress and was followed by a significant increase in the strain anisotropy. No correlation was found between the orientation of the principal radial strain before peak stress and the orientation of the shear bands observed after peak stress. These results indicate that localisation of shear bands only affects the radial strain after peak stress in these materials.

This is of particular interest because the rock mass surrounding the proposed repository is highly fractured and YM is located in a seismically active region. This paper analyzes rockfall phenomena by simulating the behavior of an unsupported emplacement drift undergoing repeated seismic ground motion after subjecting it to in situ stress and, for some cases, a time-decaying thermal load generated by the emplaced wastes. Preliminary modeling results show that fracture pattern and block size have a controlling effect on the number of blocks falling simultaneously, the extent of rockfall, and the overall drift stability. Other factors that may affect rockfall are also discussed, including characteristics of seismic ground motion, model setup, and rock and fracture thermal-mechanical properties.

Field methods for determination of rock strength at a site use the Point Load and Schmidt Hammer testers. Core drilling from the surface is costly and, if performed from the excavation, it is also interfering with operations. The presented method of borehole penetrometer testing combined with borescoping, allows for inexpensive and convenient characterization of strength distribution of intact rock around the excavation. Small drill holes 38.1 mm (1.5 in) in diameter, that can be drilled by any bolting machine. Such holes can be drilled in any direction according to the engineering interest and geologic composition of strata around the opening. Rock strength is determined by the indenter forced into the wall of the drill hole. The result is obtained within 15-30 seconds. Standardized indenters allow for breakage of any rock from soft shale and coal to the strongest igneous rock. The same holes are viewed by the miniature color TV camera, where joints and strata changes can be seen and recorded. Principle of work and possibility of application of proposed system are discussed with examples of the results obtained from field investigations.

The tests include injection into reactive and competent shales, high permeability sands, and multi-layered formations of varying permeability. Specific details of proposed fracture mechanisms have been confirmed or, where found to be inappropriate, these have been refuted. The results of these experiments help confirm the adequacy of design of injection operations and will continue to assure safe containment of the drilling waste.

These tests were repeated after niche excavation. Increases of nearly two orders of magnitude were measured between the pre-excavation air-permeability values and the post-excavation air-permeability values. These increases could be interpreted as the opening of pre-existing natural fractures induced by stress releases associated with niche excavation. For the horizontal fractures above the niche, the effective fracture apertures increased with the unloading and removing of rock mass in the niche opening. The pre-excavation permeability distribution was used to characterize the initial fracture aperture distributions. Stress redistribution was evaluated with simple continuum models. The fracture opening and the corresponding fracture permeability increases associated with the stress releases were calculated. Calculated post- to pre-excavation permeability ratios compared well with the measured values for most of the borehole intervals.

The test specimen is a 0.25 X 0.25 X 0.50 m rectangular prism bisected by an artificial (saw-cut) fracture orthogonal to the tuff fabric. Water was supplied by a point source at the center of the fracture under various pressures of up to 0.04 MPa. Both fluid flow and mechanical properties were found to be anisotropic and strongly correlated with the ash flow fabric. Fluid mass-balance measurements revealed that only minor imbibition of water occurred through the fracture surfaces and that flow rates were independent of normal stress to 14.0 MPa and temperature to 140 degrees C. Flow through the fracture occurred largely through un-correlated porosity that intersected the fracture plane.

Fully grouted rock bolts will provide support for removable wedges exposed in the excavation, which will be subject to a peak horizontal earthquake acceleration of 0.62 times gravity under the design earthquake loading conditions. Since large wedge failures could damage the new tower, the performance of the rock support under seismic loading was considered explicitly in the design process. A displacement-based inelastic design methodology was developed to determine support requirements for the tower excavation under seismic loading. The maximum design load on the rock bolts, when permitted to yield inelastically, is considerably less than the peak dynamic loads associated with the design earthquake. This design method justified the use of a pseudostatic acceleration that is approximately 35 percent less than the peak ground acceleration.

This paper reviews the results of geologic mapping and observations, displacement monitoring, and supplemental stabilization design at four specific locations, including two portals and three interior reaches of tunnel. Supplemental stabilization (rock reinforcement deeper than 3.7 m and shotcrete greater than 50 mm minimum thickness) was deemed necessary where (a) convergence in the top heading excavation was at least 8 mm, (b) convergence during and immediately following bench excavation was at least 50 mm, and (c) convergence after bench excavation was at least 8 mm. A more conservative approach to supplemental stabilization was taken at the Shoshone Portal, because of the existence of loosened rock, narrow pillars, and deep abutment cuts. Supplemental stabilization consisting of deep rock reinforcement and extra shotcrete was most effective when installed early in the excavation sequence (before bench excavation) through a given tunnel section. Overall ground conditions were good, but locally troublesome ground conditions (based on overbreak and the need for supplemental stabilization), included highly altered granitic rock with clay infilling in joints. The use of rock reinforcement and shotcrete was well suited to the ground conditions and multiple face excavation sequence on the project.

In this regard, viscoplasticity is the simplest extension of the standard elastic model, limited by rock mass strength, into the time domain. The main consequence of viscoplasticity is time-dependent displacement, above the elastic limit, that grows with ever increasing strain, although at a diminishing rate. Rounded stair-step displacement versus time curves are similar to those often observed in the field. Such a process cannot continue indefinitely and must either approach equilibrium or terminate in fast failure.

Design of the excavations, and monitoring of construction activities was focused throughout on ensuring minimal damage to the existing buildings by (i) requiring extremely high standards of perimeter excavation control and (ii) pre-supporting all areas of the bedrock that were load bearing. All areas where possible excavation-related displacements could compromise the stability of the existing walls or heavy towers were monitored with a comprehensive arrangement of instrumentation, positioned on the basis of extensive 2D and 3D modelling undertaken to optimize excavation geometry and reinforcement layouts.

Although the host rock consists of hard brittle material, creep-like movements of the order of 0.6 mm/h have been observed in certain areas. This paper describes measurements of time-dependent deformation in three different geotechnical environments. The time-dependent behaviour is the result of the rheology of the mining-induced fracture zone surrounding the excavations at these depths, while pre-existing discontinuities such as bedding planes also play a prominent role. It appears that detailed monitoring of stope closure profiles can provide a useful signature of the geotechnical response of the rock mass to the mining process. The closure profiles are simulated using a displacement discontinuity framework that allows for the time-dependent failure processes. Preliminary studies indicated that the initial jump in stope closure after blasting is correlated with the stope face stress.

This paper presents an approach to characterize the fracture system of a systematically fractured rock and to apply crack models to describe the deformation and failure behavior. From various laboratory tests, the characteristic deformation and failure mechanism was examined. Based on the crack information obtained from the laboratory tests, the nonlinear stress-strain behavior of the rock specimen was calculated. Finally, the mechanical model has been implemented into two-and three-dimensional numerical analyses. The results predicted by using the crack model were compared with the results obtained from the laboratory.

After reviewing some features of the shear behavior of rock joints, the authors present a set of constitutive equations that describes the complete stress-displacement surface. The proposed model, called CSDS, is compared with test results obtained from direct shear tests under constant normal stress and constant normal stiffness conditions. It is shown that the CSDS model can be used to estimate the post-peak stiffness of rock joints needed to establish whether slip is stable or unstable.

Knowledge of the created hydraulic fractures was critical for determining the placement of core-through wells to evaluate the "disposal domain" or fracturing mechanisms for both sandstone and shale intervals. Through real-time monitoring of the fracture geometry it was possible to detect fracture height growth during the test and insure that the injected fluids stayed in the intended zone. Also presented is a novel approach for determining fracture closure stress using downhole tilt analysis. The implications for hydraulic fracturing growth modeling are addressed.

Using Monte Carlo simulation and the ground-support interaction model different sources of uncertainty can be integrated into the analysis allowing for determination of the reliability of a support section. Two example applications are presented which aim at demonstrating the benefits from adopting the proposed technique both as a back-analysis and a design tool for tunnel design. The binomial distribution is used to assist in the definition of the acceptable level of probability of failure which is a function of the application length of a section type. The role of correlation between variables defining the support capacity and the required pressure for ground-support equilibrium is discussed with reference to design variability (considered manageable at the face) and uncertainty (considered as unmanageable). Despite some limitations the proposed approach provides a meaningful and practical technique for evaluating the reliability of a tunnel support section.

The system is an extension of continuous monitoring systems employed in mines [e.g. Gibowicz & Kijko 1994, Talebi et al. 1994] and builds on many of the learnings from oil field applications where the azimuth and extent of hydraulic fractures have been mapped with similar systems [e.g. Talebi et al. 1994, Warpinski et al. 1997]. The primary application of the system described herein is to identify and prevent casing or well failures. This objective can be achieved by observing and interpreting the events associated with (i) a fluid release and induced fracturing, (ii) movements in the rock that can lead to casing damage and failure, and (iii) the actual breaking of a casing. That latter represents a novel application of microseismic monitoring and has been supported by theoretical developments and field observations.

The physical model tests show a close resemblance to the developed numerical analysis using fitted creep parameters determined by triaxial creep tests. At lower boundary stresses there was no obvious creep but as the boundary stresses increased the model displayed primary and secondary creep. The non-linear creep model using stress-dependent creep parameters, assigned according to the changing stress conditions in the creep process, appears to be a more rational approach to time-dependent behaviour than the traditional linear creep analysis.

A systematic way of dealing with spatial variability of soil and rock using random field model is introduced and used to characterize the properties of a weak sedimentary rock. Material spatial variability is analyzed to estimate the distance within which the material property shows relatively strong correlation from point to point. Materials like shales could experience substantial loss of strength after reaching peak strength. Therefore, material spatial variation of a shale is characterized using the random field model based on the Brazilian tensile strengths tested at close intervals along a bore hole. The correlation distance and scale of fluctuation of the shale along the vertical direction are found. The correlation distance can be used for suggestion of future sampling program and for numerical simulation.

A fully coupled pore fluid diffusion-solid deformation analysis with time-dependent rock parameters is presented which clearly shows the possibility of rock shrinkage, depending on the in-situ conditions and rock properties. The sensitivity analyses confirmed the importance of considering the effective stress coefficient as time-dependent, in opposition to conventional viscoelastic models. It was also found that small changes in this coefficient can significantly alter the strain pattern, and thus, the stress magnitude computations.

The stability of keyblocks subjected to a range of directions of a fictitious loading or support force is analyzed using linear programming. Based on this optimization procedure, a keyblock can be classified as stable, unstable or potentially unstable. The range of loading force where a keyblock may be potentially unstable (uncertainty in stability) is affected by the indeterminacy of the force system and the angle of applied load. For a wide range of applied load angles, the uncertainty is small. Hence, the technique presented here would provide useful results for design.

Injections were performed in sandstone and shale formations at depths of 830 and 595 m, respectively. Typical injection disposal was simulated using multiple small-volume injections over a three-day period, with long shut-in periods between the injections. Microseismic monitoring was achieved using a 5-level array of wall-locked, wireline-run, triaxial-accelerometer receivers in a monitor well 76 m from the disposal well. Results of the mapped microseismic locations showed that the disposal domain was generally aligned with the maximum horizontal stress, with some variations in azimuth, and that wide variations in height and length growth occurred with continued injections. These experiments show that the cuttings injection process can be adequately monitored from a downhole, wireline-run receiver array, thus providing process control and environmental assurance.

The Tunnel Sealing Experiment consists of two instrumented bulkheads, one of low heat high performance concrete, the other of highly compacted bentonite-sand blocks which seal a central section of the tunnel filled with permeable sand. The central portion will be pressurized incrementally via piping water through boreholes to 4 MPa, to characterize the performance of the bulkheads in preventing axial flow along the tunnel. The bulkheads were designed with cut-off keys to stop flow through the excavation damage zone. The design of these keys required a thorough understanding of the in situ stress tensor. The role of rock mechanics in the design of the Tunnel Sealing Experiment is reviewed along with the construction of this experiment.

The objective of the in situ stress measurements was to define magnitudes and directions of the principal in situ stresses for the design and performance assessment of the future high level nuclear waste repository site. The vertical stress, sigma (sub v) , was estimated from the weight of the volcanic tuff overlying the test-hole to be 4.7 MPa. The hydraulic fracturing tests yield two principal horizontal stresses as follows: sigma (sub h) = 1.7 (+ or -0.1) MPa acting at N75 degrees W (+ or -14 degrees ); sigma (sub H) = 2.9 (+ or -0.4) MPa acting at N15 degrees E (+ or -14 degrees ). The measured stress regime reveals that both horizontal stresses are clearly smaller than the vertical stress, suggesting normal faulting stress regime. This inference is supported by the local predominance of generally N-S trending normal faults related to the Basin and Range Province. Stress indicators such as fault slip and earthquake focal mechanism data around Yucca Mountain also indicate normal faulting stress regime with the minimum horizontal stress generally oriented at E-W.

The device is able to sustain loads while undergoing large axial displacements and could act as a grout tube for grouting the surrounding rock mass. Although the device has not been tested in shear it is expected to have high shear resistance. Pull-out strength and maximum axial displacements before ultimate pull-out can be controlled by the type of grout or by design of the tube.

More recently, several studies have been carried out to assess the hydromechanical behavior in dam foundations as the reservoir is raised. Monitoring of well instrumented dam foundations during reservoir filling can be construed as a full scale coupled hydromechanical shear test of governing rock mass discontinuities. Observations and measurements at two key dams are presented and evaluated in this paper. These observations indicate that foundation rock discontinuities experience considerable deformation and concurrent increase in pore pressures above a certain reservoir level, resulting in a non elastic behavior. Important factors that control this behavior are joint attitude and hydromechanical parameters as well as the shape of the dam, site geology and depth and type of foundation treatments.

The fluid indices are empirical functions of the proppant concentration and temperature. The finite element method is applied to carry out the calculation. Simulated results show that the fracture grows initially without proppant. As pumping continues, proppant screens out at the fracture tip arresting further fracture growth, and thereafter the fracture width becomes wider and the net borehole pressure increases rapidly as proppant concentration inside the fracture increases. In general, the fracture opening width increases with decrease of rock modulus and fluid leakoff rate, but the relationship is not linear. The distribution of proppant inside the fracture affects significantly the size and the opening width of the fracture.

The treatment was carried out between 2756 and 2838 m depth and consisted of three separate injection phases. Event locations were obtained based on P- and/or S-wave arrivals and direction vectors, to an accuracy of 14 to 24 m. Spatially, the event locations were contained within the perforation interval, and outlined a hydraulic fracture 560 m in length and 60 m in width, that was symmetric about the treatment well (TW), and followed the predicted N70E trend. Nearly 50% of the events occurred over the short interval 90 m to 120 m east of TW. Over this interval, b-values, as calculated between-1.5 or =-0.4, were above 1 during the initial two injections, and seismic activity levels, evaluated at M = -0.8, increased relative to other parts of the fracture. During the third injection, the fracture growth eastwards was accompanied by b-values above 1. To the west of TW, b-values ranged from 0.5 to 1 for all three injections, however, the third injection was accompanied by an increase in seismic activity. Based on these observations, we suggest that microseismic event locations can be used to define the overall dimensions of the hydraulic fracture, and that frequency-magnitude parameters can potentially be used to identify differences in fracture growth and failure mechanisms.

This RCI is at least comparable and shows evidence of being superior to the unconfined compressive strength (UCS) for indicating a rocks resistance to disc based excavation. The results from 3 different sized cutterhead tests in 5 rock samples were then examined to determine the usefulness of the RCI. By utilizing the RCI or the UCS to determine the resistance to excavation of the rock, a linear relationship was discovered between the horsepower to cutterhead diameter ratio and the excavation efficiency of the cutterhead. This relationship allows a contractor to accurately estimate machine advance rates from a small sample of core.

The actual measurements of strength parameters from a limited sample test (hard data) are combined with other sources of information (subjective soft data) to characterize the localized probabilistic model of in-situ strength parameters. The sequential Gaussian co-simulation technique was introduced to achieve the localized probabilistic characterization of in-situ strength parameters. The bivariate probability distribution was applied for the probabilistic joint model of strength parameters (c-phi ). In other words, the full statistical distribution of strength parameters are obtainable for every local point within the geological domain. These localized probabilistic models provide the necessary input for probabilistic structural analysis, such structures as slopes, dams, foundations or underground openings, where c and phi are applied for the structural design.

The use of circular scanlines eliminates the orientation bias associated with straight scanlines while still achieving the time efficiency of scanlines. Application of the estimator to synthetic and real fracture trace maps is discussed. The utility and efficiency of the circular scanline intensity estimator make it a valuable tool for fracture studies.

Welded tuff was taken from Alcove 5 of the Exploratory Studies Facility at Yucca Mountain, and nonwelded tuffs from four lithostratigraphic units were obtained from the USW SD-7, USW SD-9, and USW SD-12 drillholes. Thermal conductivities were measured for six welded and six nonwelded specimens under dry, saturated, and approximately ten intermediate moisture conditions. All thermal conductivity tests were conducted at 30 degrees C and at atmospheric pressure. A linear and commonly used nonlinear curve were fitted to the data and the goodness of fit determined. The linear relationship provides a better fit to the data, as indicated by the sum of the squared errors.

The method incorporates time domain (damped) least square inversion. The approach uses a long segment of quantitative input made possible by use of an NBS-type high-fidelity sensors. The derivation of this unique approach is given, as are synthetic examples which show that source functions can be identified effectively through this method. If the source is contained within the sensor array, the estimated source functions contain less noise than if the source is outside the array. The beginning part of the estimated source functions is unbiased. The estimate for the trailing segment is biased for the case of weak P-wave arrival, and is less biased for strong P-wave arrival.

It is analyzed by a time-dependent, cracked beam-column finite element program and by a plate and plane stress finite element program with load coupling to model cracking. Both codes predict deep cracks in the upper surface of the plate where it is fixed to the walls. They also predict extensive cracking in one region of the lower, observable surface of the plate. The observed roof cracks are strongly influenced by pre-existing joints. The analyses suggest that long-term (1 million year) compressive strength is not exceeded even in cracked sections, and that the roof is stable.

The method presented is unique to rock mechanics applications and provides a relatively simple tool that can be used for mine planning and stability assessments. The application of the method is illustrated with site data and observations from an actual mine.

Slip displacements along bedding simultaneously reduce the physical dimensions of stopes and increase compressive stress along stope margins. Such changes, in turn, contribute directly to rock bursts and the sudden failure of volumes of rock and cemented sandfill surrounding stopes. The distribution of seismicity and several mining-induced and premining structures resemble those described in South African gold mines. These suggest fundamental similarities in seismic sources and mechanisms of rock burst damage.

A stratified percolation algorithm was used to generate individual fractures with spatially correlated and uncorrelated aperture distributions. These fractures were arranged on a cubic lattice to produce a fracture network with intersections. The relative permeabilities of the resultant fracture network were determined using an efficient network flow model. Statistical flow properties of the fracture networks were obtained by examining the results of a large number of realizations from each fracture network configuration. In general, networks of uncorrelated fractures were observed to have lower non-wetting saturations at cross-over than correlated fractures. Numerical fracture networks containing fractures with a range of average apertures were found to most closely approximate experimentally determined values of relative permeability of coal cores.

Effective characterization of fractured bedrock flow results when hydraulically active fractures and fracture zones are first identified using flow logs, and then the hydraulic properties of these active zones are given by subsequent hydraulic tests. A more difficult technical problem is relating the hydraulic properties of the few specific fractures that serve as borehole entry ports to the large-scale hydraulic properties of the surrounding rock mass. This problem is addressed through a generalized borehole flow model inversion formulated so that the boundary conditions at the outer edge of the boundary layer can be inferred from the properties of measured borehole flow.

The terrain varies from a deep rocky facies made of sericitic and chloritic phyllites to a surficial facies composed of a chaotic mixture of schist chunks and phyllitic blocks highly rich in quartz. Characterized by a slow viscoplastic movement, a landslide made the central-lower part of the village so hazardous that every building and infrastructure was destroyed in the time span of a century, with a threat to involve the entire village. The main components of the intervention are reinforced concrete beams resting on closely-spaced 40-m-long micropiles and horizontally constrained by 40-m-long anchors. Drains and environmental design works rehabilitated the area from a pedologic point of view. After the works' completion, the monitoring system revealed that the landslide stopped its destructive movement, at variance with many other similar landslides in the same province.

Disposal of drill cuttings is of importance from both economic and environmental perspectives. The paper provides the field setting where the experiment was conducted, the formations selected for injection, the technical scope of work, the series of experiments conducted, and data acquired. The project consisted of three phases completed in 1998: drilling of the injection well and two observation wells, conducting about 20 intermittent cuttings-slurry injections into each of two disposal formations while imaging the created fractures from the observation wells, and coring through the imaged disposal zones by sidetracks from one of the observation wells.

Each sub-array consists of transducers permanently installed in three holes arranged in an "L" shape. By appropriate arrangement of the transducers and selection of transmitter-receiver pairs, an active array was created that would allow the measurement of transmitted signal velocities and amplitudes (for attenuation studies) along 270 paths parallel, perpendicular and tangential to the shaft walls. Installation occurred over a period of about two years beginning in early 1989, with nearly continuous operation since that time. We now have up to eight years of data relating to the time-dependent deformation of in situ salt under well known boundary conditions at various stress levels determined by the three installation depths. Results show changes in elastic wave velocity as function of vertical depth, distance from shaft wall and orientation.

The methodology was modeled after the Rockfall Hazard Rating System developed for the Federal Highway Administration and modified to better suit the urban commercial and residential environment. The rating system includes the following input: slope height; distance of cultural feature from the toe of the slope; occupancy frequency; existing mitigation measures; rockfall history; water pressure estimates based on visual observations; the location of observed joints relative to each other and to the slope face; and stability analysis. The output is a Rockfall Hazard Rating (RHR) for individual slope sections. Mitigation costs were estimated for slope sections based on reconnaissance level designs and unit costs, factored by an access-type rating. The independent evaluation of RHR and mitigation cost for individual slope sections provides a basis for targeting limited resources towards optimal risk reduction in a complex urban setting.

Estimating these parameters from field data is beset with problems due to censoring and length bias. The paper presents simple distribution-free estimators for mean trace length and density that automatically correct for sampling bias. The estimators use samples collected with circular windows placed at random on exposed pavements or rock surfaces. Use of the estimators is demonstrated by application to synthetic and real data sets.

With respect to the expected values due to gravity forces alone, the results in the heart of the Ambin Massif globally show a marked deficit of vertical stress, and an excess of horizontal stress. The analysis of these results has been performed by using numerical 2D and 3D modeling, to study the respective influence of local topography and of global tectonic stresses on the natural stress field.

This zone has a fundamental importance for defining the system behavior in terms of the post-peak instability and in terms of material strength such that size effects appear. This paper illustrates the change in the load-displacement response and presents evidence of the process-zone development with varying specimen size. It is demonstrated that fracture problems do not require geometric or material nonlinearity to produce instability. The size of a structure that fails by fracture is an important factor. Furthermore, experiments suggest that an intrinsic zone develops in rock as a material characteristic. Because of this intrinsic length, two competing factors define the nominal strength--the positive contribution of the process zone and the depleting aspects of the undamaged volume, that is, the size.

Analyses were based on mechanical parameters derived through empirical correlations with rock-mass quality, Q. In the presence of stiff ground support, potential instability is higher in areas of higher Q (within the range of Q values used in the model) and is most intense at the middle of inter-drift pillars. With degraded ground support, potential instability is higher in areas of lower Q and is most intense in the roof and floor areas of the drifts. Site-specific data defining the relationships between rock-mass quality and mechanical properties are required to reduce the uncertainties associated with such calculated results.

The effect of the specimen thickness B, the dimensionless notch length a/W as well as the notch inclination angle alpha on the determination of K (sub IIC) has been experimentally studied. The results show that the apparent mode II fracture toughness K (sub c) decreases as B and a/W increase and becomes constant when B> or =70 mm (i.e. cubic specimen) and a/W>0.5. The K (sub c) is almost independent of alpha in the range of 65 degrees -75 degrees . The constant K (sub c) is about 2-3 times that of mode I fracture toughness K (sub IC) and can be considered as the true mode II fracture toughness K (sub IIC) of rock.

A key element in this work has been to establish quantitative relations between static and dynamic moduli. The work was based on analyses of laboratory tests where both static moduli and sound velocities were measured simultaneously. The results of these analyses showed significant differences between the static and dynamic moduli even for dry rocks, under both hydrostatic and uniaxial loading. The differences were found to be strongly dependent on stress and strain. The relations between the static and dynamic moduli have been described by a set of mathematical formulas. These formulas allow for quantitative descriptions of the relations between static and dynamic moduli in weak sandstones, and give a foundation for predictions of how such materials will respond to changes in stress and strain.

In order to investigate the relaxation behavior of salt rock, stepwise relaxation tests were performed after the sample had been subjected to different pre-relaxation creep strains and confining pressures. Results show that the lateral strain was almost constant during relaxation. Stress relaxation decreases with increasing confining pressure. The pre-relaxation creep strain very greatly affects the relaxation behavior of salt rock.

In addition, the developed governing equations follow rigorous volume fraction basis, instead of being proposed via phenomenological intuitions adopted in many existing dual-porosity models. The significance of this approach rests on its ability to include additional components of fluids as well as solids, as they may be needed in the actual reservoir simulation.

The thermo-hydraulic experiment was designed to determine a hydro-thermal coupling parameter as well as the permeability and the thermal and hydraulic diffusivities of the Lac du Bonnet granite. Several water injection and heater tests were conducted during this experiment. In an injection test, a given volume of water is pumped quasi instantaneously in a sealed-off interval of the borehole, while in a heater test, heat is produced at a constant rate over a certain period (ranging from about one day to several weeks). The experimental set-up involves a heater installed in a sub-horizontal borehole drilled from an underground gallery, and piezometers and thermistors located at different distances from the heater, in auxiliary boreholes drilled from an adjacent gallery. Determination of the material parameters relies on matching the measured pore pressure and temperature responses with the theoretical predictions based on singular solutions of thermoporoelasticity.

Using a finite-difference code, we compute thermal stress changes. We evaluate possible permeability enhancement resulting from shear slip along various mapped fracture sets after 50 years of heating, for rock in the near-field environment of the proposed repository. Our results indicate permeability enhancement of a factor of 2 for regions about 10 to 30 m above drifts, for north-south striking vertical fractures. Shear slip and permeability increases of a factor of 4 can occur in regions just above drifts, for east-west striking vertical fractures. Information on how permeability may change over the lifetime of a geologic repository is important to the prediction and evaluation of repository performance.

In the late 1940's and early 1950's, the first true design methods--as opposed to simple pinning of loose materials--used suspension load carrying concepts. Next, the beam and friction approach to optimize fiber stresses in roof beams was developed. Later methods, in the middle to late 1950's and 1960's, relied upon rock arch development, confining stress maintenance and shear reinforcement, and rock arch thrust capacity. Theoretical approaches were developed, beginning in the 1930's but peaking in the 1960's and 1970's, such as the "ground reaction curve", using the changing stiffness with time of the deforming rock mass and the supplied reinforcement or support to optimize the reinforcement effort. Empirical methods arose as more experience was gained and the subsequent methods used ratios of span to bolt length, ratios of mined height to bolt length, calculation of the equivalent support pressure, and rock mass ratings with stand-up time and bolting needs estimation from pure empirical findings or through roof loosening estimates. Physical models were also used. Numerical modeling was developed in the late 1960's which allowed incorporation of rock reinforcement elements in two- and three-dimensional models of excavations. In the early 1980's, the keyblock concept evolved for identifying and reinforcing the "keystone" block in an arch or wall of fractured rock, minimizing reinforcing requirements. The evolution of rock reinforcement design from early suspension and beam and friction concepts, to rock arch maintenance and modeling all have the common thread of helping the rock mass to help itself as a support. Future challenges lie in characterizing the rock mass appropriately and realistically.

Core disks were characterized by nearly uniform thickness for a given stress condition and by a "trough" shape with the trough axis oriented in the direction of the far-field maximum horizontal principal stress. A thin section study revealed that the core profile shape is the result of subhorizontal extensile cracks developed at the root of the core stub. Measuring the average disk thickness for each pre-determined true-triaxial stress condition, and using a nonlinear regression analysis, enabled the establishment of a quantitative relationship between disk thickness and the three principal stress components. The relationship enables the estimation of the magnitude of the maximum horizontal principal stress from knowledge of disk thickness if the magnitudes of the other two principal stresses are independently known.

Predicting water-gas flows occurring within a network of rock joints under mining conditions is a very difficult task, due to the wide array of hydro-geological variables involved. This paper describes the laboratory investigation of two-phase flow (water and air) through jointed rock specimens for different stress conditions. Findings of this study show that unsaturated flow through rock specimens can be described using the modified Darcy's law. At a given confining pressure and permeating inlet pore pressures, two-phase permeability is decreased significantly compared to single-phase permeability. As in single-phase flow, two-phase flow volumes decrease significantly with increase in confining stress until discontinuities and pores attain to their minimum values.

In the SHT, a horizontal, 5-m-long, line-heat source was used to heat a rock pillar for nine months. Moisture movement was monitored during and after heating using electrical-resistance tomography (ERT) and neutron-logging techniques. Results indicate drying in regions of the rock where temperature reached 60 degrees C and above. The drying zone is asymmetric and is not centered on the heater, but has lobes extending above and to the sides of the heater. Predicted temperatures agreed well with observations. A coldtrap effect was predicted, in the heater borehole, that efficiently transfers heat along the heater borehole to the excavation wall. A simple thermomechanical analysis of the SHT shows that shear zones predicted for vertical fractures coincide with regions of increased moisture content derived from ERT measurements.

It is the authors conviction that quantitative classification systems should not be used to determine supports during planning and construction of a tunnel. Instead of rock mass classification we recommend to select design parameters, tunnel support, type of excavation, working sequence, etc., and to estimate construction time and costs on the basis of rock mass models which are achieved by adequate rock mass characterization, assessment of initial stress and analyses of stress redistribution, deformation behavior and potential failure models. Practical application and benefits of rock mass modeling for the design of tunnels is demonstrated by case studies from the Austrian Alps and Greece.

This paper is discussing the issue based on research having been performed at the Norwegian University of Science and Technology (NTNU) on the rock engineering aspects of the Norwegian subsea tunnels. Particular emphasis is put on results of a recent study of the Froya subsea tunnel, which is currently under construction, and where very difficult rock conditions are expected. It is concluded that distinct faults or weakness zones generally represent the most difficult rock conditions. Major water inflows seldom are directly connected to the major zones, and are difficult to prognosticate.

A more extensive adhesion strength test program was carried out which included studying the effects of accelerator concentration, time and the surface treatment method. The results from these investigations are presented in this paper. It is shown that water-jet scaling and sufficient thickness of the shotcrete give favourable conditions for the use of unreinforced shotcrete as rock support. The result of the tests carried out in Kiirunavaara shows that the adhesion strength has a wide range of variation.

The thermo-poroelastic model includes heat conduction caused by temperature differences between the formation and the drilling mud, and pore pressure diffusion due to differences between the formation pore pressure and the pressure in the wellbore. As it only handles conductive heat transport, the model is limited to formations with very low permeability where the heat transport associated with pore fluid diffusion can be neglected. Observation of drilling-induced fractures means that at some time between drilling and logging the tangential stress at the borehole wall was tensile. The model calculations are used to determine a range of magnitudes of the greatest horizontal principal stress which cause tensile stresses at the borehole wall. The results indicate a strike-slip stress regime for the northern North Sea. However, non-linear material behavior and chemical influences of the drilling mud on the shale are not considered in the model and may change the conclusions of this work with respect to the stress magnitude.

Modeling results suggested a plausible explanation for the separation of rock blocks, and the deteriorated function of the culverts. Agreement between calculated and measured displacements was fairly good. Numerical modeling showed that block separation could be prevented by installing pre-tensioned tendons in the culvert. However, the deformations caused by passing trains only account for part of the total deformation. Other factors, such as frost action, significantly affect the separation magnitude, and need to be studied further. These results have direct application to the currently ongoing upgrade of the railway system in Sweden, to allow larger train loads.

Using synthetic rocks formed under stress, we show how stress dependent/plastic deformation and core damage may affect the predicted stress paths. Further, consequences of scale effects in fractured reservoirs, and of Biot's alpha being different from unity, are demonstrated. In order to gain more insight into the response of reservoirs during depletion, the quantity and quality of in situ compaction and stress monitoring data need to be improved.

During the last five years, the National Park Service developed a partnership with the U.S. Geological Survey's National Water Quality Assessment Program. This national program was directed by Congress to assess the status and trends of our Nation's water resources, particularly in the area of water quality. Last year, the National Park Service expanded this partnership through the Clean Water Action Plan. The concept behind this partnership is to match the policy responsibilities and management information needs of the National Park Service with the scientific capabilities of the Survey, thereby supporting the principal missions of both agencies. In fiscal year 1999, 2.5 million dollars will fund 36 projects in 32 parks through this program. Projects were designed to address high priority park problems and were developed with close coordination between agency scientists and land managers. Project findings will be presented in professional reports and interpretative products to assist park managers make policy decisions and inform the public. In the future, cooperative projects may be implemented which integrate park needs with other agency/local needs, and national water quality programs.

Produced in support of a water right application, the study included an institutional analysis of water availability for the site, characterization of the hydrology of the aquifer-stream system, and description and quantification of flow-dependent resource values. Specific objectives for the assessment were to (1) determine the physical and legal availability of water for management purposes; (2) understand the hydrology of Beaver Dam Wash, particularly the interaction of surface- and ground-water systems; (3) develop relationships between streamflow and resource values and evaluate flow requirements to maintain resource values; and (4) identify and evaluate flow protection strategies and related flow issues for management. The institutional analysis addressed the need for protection from extensive ground-water withdrawals that threaten surface flows in the area. The hydrologic characterization described ground-water contributions to streamflow at the oasis and the influence of large floodflows on channel morphology and ecological sites. The resource assessment focused on critical habitat for several special-status fish species, aesthetics and wadeability for recreation users, and consumptive use and ecological needs for riparian habitat.

The results of a three dimensional non-linear stress analysis, using FLAC (super 3D) , demonstrate that three dimensional modelling can make a significant contribution to the improved understanding of underground roadway face-end instability and reinforcement requirements. Non-linear modelling clearly illustrates the asymmetric stress effects associated with adversely orientated stress fields relative to the excavation direction. The results of the investigation provide a more realistic evaluation than earlier three dimensional elastic analyses of the problem.

Fracture spacings of recovered core were analysed using simple power law (1-dimensional fractal) relationships. A characteristic length L (sub c) was identified, where L (sub c) was conjectured to be a limit for a self-organized critical (SOC) behavior consistent with disordered systems. Assuming rock mass to be a disordered system, the SOC behavior was resistance to ripping. The rippability index (RI) was a force computed as L (sub c) squared (area) times a representative rock particle unconfined compressive strength, and was compared to available ripping forces for various bulldozers. Rippability estimates by RI were compared to rippability characterization by other methods.

Vectorized USGS geologic map data at 1:24,000 and 1:100,000 scales are being made available in ARC/INFO, ArcView, and SDTS formats for use in GIS. These data are used by earth science researchers, land managers and government entities to enhance land studies and land-use planning. The State of Missouri and the U. S. Forest Service (USFS) are developing an ecological classification of lands for the entire state using the standard USFS hierarchy of ecological units. Information is being integrated on geology, landform, soils and vegetation at Landscape (ten to one hundred square miles), Site (ten to one hundred acres), and Phase (local variants within sites) levels of the hierarchy. Geo-landforms in a GIS environment are a good coarse-scale map of soil and vegetation patterns, improve existing soil maps and act as good predictor of vegetation patterns. As an example of application of this database, the National Park Service at the Ozarks National Scenic Riverways is using data from the ecological unit maps to plan areas for controlled burning within the park. Burns are performed to renew and enhance certain plant communities, so it is most cost- and effort-effective to be able to predict the locations for these communities. Conversely, geologists correlate between plant types and certain combinations of stratigraphic units and physiographic forms and use them as guides for identifying geologic contacts, especially in areas with poor bedrock exposure. Both the Eminence Dolomite-Gasconade Dolomite and Gasconade Dolomite-Roubidoux Formation contact intervals tend to have open glades and distinctive plant communities developed on them.

There was no difference in the number of albino and pigmented medaka that died during the exposure period. Spectrophotometric analyses of the outer dorsal skin layers from albino and pigmented medaka indicated that, prior to exposure, both groups of fish had similar amounts of an apparent colorless non-melanin photoprotective substance that appears to protect other fish species from UVB radiation. Our results indicate that albino medaka were as tolerant of UVB radiation as pigmented medaka because they had similar amounts of this photoprotective substance in the outer layers of the skin.

Photomediated toxicity is often not considered, and the toxic effects of an oil spill can be grossly underestimated. The toxicity of a weathered oil collected from a monitoring well at an abandoned oil field to Ceriodaphnia dubia was examined in the presence of UV. A solar simulator equipped with UVB, UVA, and cool white lamps was used to generate environmentally comparable solar radiation intensities. C. dubia were exposed to six concentrations of water accommodated fractions (WAF) of weath-ered oil in conjunction with three levels of laboratory simulated UV (Reference = < 0.002 mu W/cm 2 UVB 3.0 mu W/cm 2 UVA Low = 0.30 mu W/cm 2 UVB 75.0 mu W/cm 2 UVA High = 2.0 mu W/cm 2 UVB 340.0 mu W/cm 2 UVA) and visible light. Seven day static renewal bioassays were used to characterize WAF/UV toxicity. WAF toxicity significantly (p <0.05) increased when the organisms were exposed to WAF in the presence of UV. The photoenhanced toxicity of the WAF increased with WAF concentration within each UV regime. Relative to the reference light regime, the average number of neonates from adults exposed to 1.6 mg TPH/L decreased significantly by 20% within the low light regime, and by 60% within the high light regime. These results indicate that organisms exposed to dissolved-phase weathered oil in the presence of environmentally realistic solar radiation, exhibit 1.3-2.5 times greater sensitivity, relative to organisms exposed under traditional laboratory fluorescent lighing.

AN - 18009244; 4695064 AB - Many people believe that marine wilderness--i.e., areas of the sea where human influences are minimized and no extractive uses are allowed--protects biodiversity, restores and sustains fisheries, provides insurance for management errors, and produces tourism industries. In spite of the apparent benefits, and in stark contrast to the proliferation of wilderness designations in the terrestrial environment, very little marine wilderness has been designated worldwide. Marine protected areas (MPAs) abound, but we afford few portions of the sea enough protection from fisheries harvest and other extractive activities to function as wilderness. Why?.

Oil mousse persisted at the sites where it was stranded in the intertidal zone under a lag of large boulders which prevented waves from disturbing the oil. Weathering of the mousse was slight showing negligible changes in PAH compared to 11 d old Exxon Valdez crude. Low ecological sensitivity ratings previously applied to exposed, rocky shorelines needed to be modified. Oil stranded on the Katmai NP&P coast was considered not to be threat because of its small amount and sequestered state. There are 41 references.

Sediment cores were collected from nearshore and offshore sites in Lake Superior and used to evaluate spatial and temporal variations in copper loading associated with mining-related activities. Although both settings have been strongly affected by anthropogenic releases of copper, copper concentrations in nearshore cores are significantly greater than those found in offshore cores, implying that nearshore copper loading is dominated by simple deposition and burial of sediment generated from mining activities. Temporal variations in copper profiles in sediments from nearshore environments closely mimic copper production rates. Conversely, copper loading histories derived from offshore sediments are not well correlated to production rates. The offshore sediment cores, when compared with analogous cores from Lakes Ontario and Michigan, show that the average, lake-wide intensity of copper loading in Lake Superior is comparable to the other two lakes, despite the fact that Lake Superior has received the largest total burden of anthropogenic copper. Cu/Zn ratios, used to evaluate the amount of copper loading derived from mining discharges, vary strongly in nearshore environments in response to loading. Cu/Zn ratios in offshore sediments are much less variable, implying that copper loading may be regulated by additional mechanisms (solution chemistry and/or biologic uptake). Study of trace metal partitioning within Lake Superior sediments indicates that the organic fraction of the sediment contains the majority of the copper. Copper concentrations in offshore sediments are significantly correlated to organic carbon content of the sediment whereas copper concentrations in nearshore sediments are not. These findings support the model that transport and deposition of particles released from mining discharges dominate copper loading in nearshore sediments, whereas biologic uptake and settling of particulate organic matter may regulate copper loading in offshore sediments.

Somatic growth is one component of production, and we hypothesized that, if the FPC applies, growth of fishes that use the moving littoral zone should differ among years with differing flood pattern, whereas nonlittoral fishes would show no such response. Growth of largemouth bass(Micropterus salmonides) and bluegill (Lepomis macrochirus), species that exploit littoral resources, increased during a year having an unusual warm-season flood in the Upper Mississippi River system and was reduced during low-water years. Growth of white bass (Morone chrysops), which do not rely heavily on the littoral zone, did not differ significantly between the extreme-flood and low-water years. Patterns of growth of black crappie (Pomoxis nigromaculatus), which have intermediate dependence on the moving littoral zone, were somewhat ambiguous. These results are consistent with the hypothesis that the FPC applies, at least under certain conditions, to this temperate river system. Our results can also provide an important basis from which to assess some costs and benefits of water level management strategies in large regulated temperate rivers.

By 1991, all native unionid (Unionidae) shells were infested by dreissenids. In 1990 and 1991, about 500 individual unionids of 15 species were collected: in 1992, 246 individuals of 12 species were collected; in 1993, 64 individuals of 6 species; in 1994, three individuals of three species; and in 1995, no unionids were found. In general, infestation indices of unionids were relatively low in 1990 and 1991, increased in 1992, and decreased in 1993. Mortality of unionids associated with infestation in the bay occurred in a shorter period of time (ca. two to three years) than has been documented in other water bodies. Observations in an area of Presque Isle not included in the present study, indicate that a small remnant population of unionids exists in the presence of heavily-colonized substrates by dreissenid mussels. Since other shallow-water areas of Lake Erie support infestation-free unionids in the presence of dreissenid mussels, it is hoped that some unionids will survive in Presque Isle Bay of Lake Erie.

Habitat factors varied in levels of disturbance outside (high) and inside (low) the DTNA, and in levels of soil nutrients in washlet (high) and hummock (low) topographic positions, in Larrea-north (high), Larrea-south (medium), and interspace (low) microhabitats near creosote bushes (Larrea tridentata), and during 1995 when rainfall was 207% (high) and 1994 when rainfall was 52% (low) of the long-term average. Dominant alien plants included the annual grasses Bromus rubens, Bromus trinii, and Schismus spp., and the forb Erodium cicutarium. Species richness and dominance of alien annual plants were slightly higher where disturbance was high, and much higher where soil nutrients were high. B. rubens and B. trinii were most dominant in washlets and in the Larrea-north microhabitats during both years. These two species evolved in mesic ecosystems, and appeared to be particularly limited by soil nutrients at this site. Schismus spp. and E. cicutarium were also most dominant in washlets, but their dominance varied between interspaces in 1994 and the Larrea-south microhabitat in 1995. Monitoring to detect the invasion of new annual plants should focus on regions of high rainfall and nitrogen deposition and on washes and beneath-canopy microhabitats. The ecological range of each alien species should be evaluated separately, because their evolutionary origins may greatly affect their patterns of invasion and dominance in the Mojave Desert.

Intensive study of a bighorn sheep herd in northeastern Utah indicated a need for range improvements. To evaluate the effectiveness of clear-cut logging and prescribed burning, we documented sheep responses to these treatments. Although bighorn sheep exhibited strong fidelity to pre-treatment areas (P>0.05), they significantly altered use patterns to include logged and burned areas (P<0.001). Treated habitats experienced 148% increases in bighorn sheep activity, whereas use in untreated areas declined by 45%. Bighorn sheep responded more favorably to logged units than to burned areas. We conclude that carefully planned clear-cut logging and range burning may be effective to enhance and expand bighorn sheep populations.

We studied food habits of radiocollared adult striped skunks (Mephitis mephitis) during 1976-78 in North Dakota, where skunks are regarded as important predators of ground-nesting birds. Plant foods, primarily grain and sunflower seeds, occurred in a larger percentage of scats in spring (15 Apr-31 May) than summer (1 June-15 July, P=0.04), but overall, plant foods were a minor part of skunk diets. Animal foods, primarily birds (including eggs), small rodents, and insects, occurred annually in a large percentage of the scats of all skunks. These foods were acquired nearly exclusively in grasslands. Percentage of scats containing animal foods was similar, irrespective of sex, season, or year (P>0.45). In spring, vertebrates occurred in a smaller percentage of scats of females than males (P0.15). Insects were mostly adult and larval Coleoptera, larval Lepidoptera, and adult and nymph Orthoptera.

We documented avian cholera mortality in breeding lesser snow geese (Chen c. caerulescens) at the Egg River colony on Banks Island, Northwest Territories, Canada, in 1995 and 1996. Area of the breeding colony, core nesting area, and number of nesting geese were greater in 1996 (colony=7,537 ha, core area=1,581 ha, 401,000 nesting geese) than in 1995 (colony=6,637 ha, core area=996 ha, 318,000 nesting geese). Density of nesting geese also was greater in the core area during 1995 (120 geese/ha) than in 1996 (90 geese/ha). Pasteurella multocida (serotype 1) was cultured from the leg bones of adult snow goose carcasses collected after outbreaks. Mortality from avian cholera began during nesting and continued until birds dispersed at hatch. Mortality appeared to be in foci scattered throughout the nesting colony, but generally was greater where there were greater densities of nesting geese. We estimated that 30,000 and 20,000 geese died in 1995 and 1996, respectively, about 5-9% of the nesting colony. Between 1991 and 1997, at least 4 avian cholera outbreaks occurred at Banks Island. It appears that avian cholera has become endemic in this population of snow geese, and these birds have the potential to transmit the disease to other waterfowl, especially on wintering areas where waterfowl are very concentrated.

Microsomes were assayed fluorometrically for four monooxygenases: benzyloxy-, ethoxy-, methoxy-, and pentoxyresorufin-O-dealkylase, in combination with each of the seven modulators. Four combinations: alpha -naphthoflavone and 2-methylbenzimidazole with benzyloxyresorufin, and Proadifen with methoxy- and ethoxyresorufin, respectively, were evaluated further. beta -Naphthoflavone-treated groups were clearly distinguished from the corn oil vehicle control group by all of the assays and by the effects of the modulators in three of the four assay/modulator combinations. Enzyme activities of the phenobarbital and saline groups were statistically similar (P greater than or equal to 0.05) when assayed without modulator added, but each assay/modulator combination distinguished between these groups. The PCB-treated group was distinguished from the corn oil vehicle control group only for BROD activity, with or without the presence of modulator. Graphing of per cent modulation of BROD activity versus initial BROD activity provided the clearest distinction between all of the study groups. Identification of these selective in vitro modulators may improve detection and measurement of low level cytochrome P450 induction in avian species. Also, both the monooxygenase activities induced and the impacts of the modulators indicated differences between mammalian and avian cytochromes P450.

Stepwise discriminant function analyses selected wing chord and tail length as the most parsimonious subset of variables for discriminating sex. This two-variable model correctly classified 80% of females and 97% of males used to develop the model. Validation of the model using 19 individuals from Louisiana and Virginia resulted in 100% correct classification of males and females. This model provides criteria for sexing monomorphic Acadian Flycatchers during the breeding season and possibly during the winter.

Robowell was developed and tested to provide a cost-effective monitoring system that meets protocols expected for manual sampling. The process uses commercially available electronics, instrumentation, and hardware, so it can be configured to monitor ground water quality using the equipment, purge protocol, and monitoring well design most appropriate for the monitoring site and the contaminants of interest. A Robowell prototype was installed on a sewage-treatment plant infiltration bed that overlies a well-studied unconfined sand and gravel aquifer at the Massachusetts Military Reservation, Cape Cod, Massachusetts, during a time when two distinct plumes of constituents were released. The prototype was operated from May 10 to November 13, 1996, and quality-assurance/quality-control measurements demonstrated that the data obtained by the automated method was equivalent to data obtained by manual sampling methods using the same sampling protocols. Water level, specific conductance, pH, water temperature, dissolved oxygen, and dissolved ammonium were monitored by the prototype as the wells were purged according to U.S. Geological Survey (USGS) ground water sampling protocols. Remote access to the data record, via phone modem communications, indicated the arrival of each plume over a few days and the subsequent geochemical reactions over the following weeks. Real-time availability of the monitoring record provided the information needed to initiate manual sampling efforts in response to changes in measured ground water quality, which proved the method and characterized the screened portion of the plume in detail through time. The methods and the case study described are presented to document the process for future use.

The outcome of a predatory encounter may be dependent upon whether both species are exposed to a contaminant simultaneously, or whether exposure occurs only in one of the species. In a laboratory experiment, I used the insecticide carbaryl to examine predation of southern leopard frog tadpoles (Rana sphenocephala) by adult red-spotted newts (Notophthalmus viridescens) under four conditions: both tadpoles and newts exposed, neither tadpoles nor newts exposed, and either newts or tadpoles only exposed. After one hour, exposed newts consumed half as many tadpoles as non-exposed newts. Carbaryl potentially affected newt activity enough to reduce time spent searching for prey, or may have altered the speed and coordination necessary to capture tadpoles. After six hours, non-exposed and exposed newts consumed similar numbers of tadpoles, most likely indicating recovery from exposure. After 24 h, predation rates were lowest when both newts and tadpoles were simultaneously either exposed or not exposed, and were greatest when newts and tadpoles were not exposed simultaneously. This study suggests that when tadpoles and newts are exposed to a sublethal level of a contaminant simultaneously, that predation rates do not differ from those observed under natural conditions, but exposure of either predator or prey at different times can disrupt predator-prey dynamics.

We designed and tested a radiocollar made of beaded-chain on 4 captive Heermann's kangaroo rats (D. heermanii). Attachment of the collar required no anesthesia, the collar was easily fitted in 1-2 minutes, and it caused minimal stress to the animals. Once the collar design and attachment technique were perfected on the surrogate animals, we fitted radiocollars on 48 giant kangaroo rats for about 15 days. Upon recapture, 12 animals showed some minor fur or skin abrasion on the neck. Overall, the attachment performed as expected and proved to be a reliable method to radiotrack kangaroo rats during our short-term field study.

Traditional indices used to monitor fisher populations typically overestimate litter size and proportion of females that give birth. We evaluated the usefulness of 2 indices of reproduction to determine proportion of female fishers that gave birth in a particular year. We used female fishers of known age and reproductive histories to compare appearance of placental scars with incidence of pregnancy and litter size. Microscopic observation of freshly removed reproductive tracts correctly identified pregnant fishers and correctly estimated litter size in 3 of 4 instances, but gross observation of placental scars failed to correctly identify pregnant fishers and litter size. Microscopic observations of reproductive tracts in carcasses that were not fresh also failed to identify pregnant animals and litter size. We evaluated mean sizes of anterior nipples to see if different reproductive classes could be distinguished. Mean anterior nipple size of captive and wild fishers correctly identified current-year breeders from nonbreeders. Former breeders were misclassified in 4 of 13 instances. Presence of placental scars accurately predicted parturition in a small sample size of fishers, but absence of placental scars did not signify that a female did not give birth. In addition to enabling the estimation of parturition rates in live animals more accurately than traditional indices, mean anterior nipple size also provided an estimate of the percentage of adult females that successfully raised young. Though using mean anterior nipple size to index reproductive success looks promising, additional data are needed to evaluate effects of using dried, stretched pelts on nipple size for management purposes.

Reduction of these population stresses has permitted significant recovery of the lake whitefish in the upper three Great Lakes since the 1980s, and limited but encouraging recovery is now apparent in Lakes Erie and Ontario. In the present study the thermal preferences of age-0 and age-1 lake whitefish were measured in the laboratory to provide a basis for determining thermal habitat use by juvenile lake whitefish and thermal niche overlap with exotic fishes that might prey on them. Final thermal preferenda of young lake whitefish varied inversely with fish size ranging from 16.8 degree C for fish averaging 1.9 g to 15.6 degree C for age-1 fish averaging 3.9 g. Final thermal preferenda were in agreement with the limited published information on temperature selection of juvenile lake whitefish in the laboratory and on thermal habitat use by wild, free-ranging populations in the Great Lakes.

These data were used to develop predictive models of brant and Canada goose response to aircraft altitude, type, noise, and lateral distance from flocks. Overall, 75% of brant flocks and 9% of Canada goose flocks flew in response to overflights. Mean flight and alert responses of both species were greater for rotary-wing than for fixed-wing aircraft and for high-noise than for low-noise aircraft. Increased lateral distance between an aircraft and a flock was the most consistent predictive parameter associated with lower probability of a response by geese. Altitude was a less reliable predictor because of interaction effects with aircraft type and noise. Although mean response of brant and Canada geese generally was inversely proportional to aircraft altitude, greatest response occurred at intermediate (305-760 m) altitudes. At Izembek Lagoon and other areas where there are large concentrations of waterfowl, managers should consider lateral distance from the birds as the primary criterion for establishing local flight restrictions, especially for helicopters.

Operation Recovery, which linked numerous ringing stations along the east coast in a study of autumn migration of passerines, and the Preseason Duck Ringing Programme in prairie states and provinces, conclusively demonstrated the feasibility of large-scale projects. The subsequent development of powerful analytical models and computing capabilities expanded the quantitative potential for further large-scale projects. Monitoring Avian Productivity and Survivorship, and Adaptive Harvest Management are current examples of truly large-scale programmes. Their exemplary success and the availability of versatile analytical tools are driving changes in the North American bird ringing programme. Both the US and Canadian ringing offices are modifying operations to collect more and better data to facilitate large-scale studies and promote a more project-oriented ringing programme. New large-scale programmes such as the Cornell Nest Box Network are on the horizon.

We ringed Lesser Snow Geese Anser caerulescens nesting at Wrangel Island, Russia and Banks Island, Canada with metal rings and individually coded plastic neck-collars or radio-transmitters to determine survival, movement and cause of death. We vaccinated half of the neck-collared and radiotagged geese to provide protection from avian cholera for up to one year following ringing and thus experimentally determine the impacts of this disease on survival. We found that vaccination did not reduce short-term survival of the experimental birds, compared with control geese. Neck-collared geese vaccinated in 1993 at Wrangel Island had higher survival during winter 1993-94 than control birds. In contrast, we found similar survival during winter 1994-95 between vaccinated and control geese neck-collared in 1994 at Wrangel and Banks Islands. Survival of radiotagged geese on wintering areas during 1994-95 was consistent with the vaccination versus control results for neck-collared geese during the same winter. However, we found that radiotagged geese that were vaccinated had better survival than control geese during winter 1995-96. We believe that harvest and avian cholera are the two principal causes of mortality for Lesser Snow Geese wintering in the Pacific Flyway and that avian cholera may be one of the factors affecting these populations.

However, widespread eradication, habitat loss, and sylvatic plague (Yersinia pestis) have reduced their numbers by 98% since historical times. Birds associated with prairie dogs also are declining. Potential nest predators, such as coyotes (Canis latrans), swift foxes (Vulpes velox), and badgers (Taxidea taxus), may be attracted to colonies where a high concentration of prairie dogs serve as available prey. Increased abundance of small mammals, including prairie dogs, also may increase the risk of predation for birds nesting on colonies. Finally, because grazing by prairie dogs may decrease vegetation height and canopy cover, bird nests may be easier for predators to locate. In this study, we placed 1,444 artificial ground nests on and off 74 white-tailed prairie dog (C. leucurus) colonies to test the hypothesis that nest predation rates are higher on colonies than at nearby off sites (i.e., uncolonized habitat). We sampled colonies from 27 May to 16 July 1997 at the following 3 complexes: Coyote Basin, Utah and Colorado; Moxa Arch, Wyoming; and Shirley Basin, Wyoming. Differences in daily predation rates between colonies and paired off sites averaged 1.0% (P = 0.060). When converted to a typical 14-day incubation period, predation rates averaged 14% higher on colonies (57.7 plus or minus 2.7%; \m?\x plus or minus SE) than at off sites (50.4 plus or minus 3.1%). Comparisons of habitat variables on colonies to off sites showed percent canopy cover of vegetation was similar (P = 0.114), percent bare ground was higher on colonies (P 0.288). Although we found the risk of nest predation was higher on white-tailed prairie dog colonies than at off sites, fitness of birds nesting on colonies might depend on other factors that influence foraging success, reproductive success, or nestling survival.

We estimated species abundance, richness, and evenness using data from 312 point counts in 18 burned sites and six unburned sites. We measured gross habitat features in 0.04-ha circles centered on each point count station. We calculated productivity estimates at nests of seven of the most common nesting species. Habitat components we measured in 1-, 2-, and 3-yr post-burn sites were similar, but most components differed between burned and unburned sites. Although 98 species were detected during point counts, we report only on the 46 species that nested in the area and were detected greater than or equal to 10% of the counts in either habitat class. Twenty-one species preferred burned sites and six preferred unburned sites. Avian species richness and evenness were similar for burned and unburned sites. Burned sites were preferred for nesting over unburned sites. Only nine nests of six species were found in unburned sites. Productivity estimates were low in burned sites. One or more eggs hatched in only 59 of 187 nests monitored, and an average of only 0.82 chicks per nest were estimated to have fledged. Predation was the most common probable cause for nest failure, ranging from 45% in the Northern Cardinal (Cardinalis cardinalis) to 64% in the Summer Tanager (Piranga rubra). Because the sources of predation at the refuge are unknown, future research should address this issue.

We used radiotelemetry to estimate survival rates of immature mallards (Anas platyrhynchos) from fledging to autumn migration in northcentral Minnesota. We monitored 48 females and 42 males during 1972-74 and observed 31 deaths during 2,984 exposure-days. We attributed 7 deaths to predation and 24 to hunting. Survival rates were 0.86 (SE = 0.047) for the postfledging-prehunting period, 0.29 (SE = 0.107) from the onset of hunting to migration, and 0.25 (SE = 0.094) for both periods combined. Natural mortality of fledged young had a negligible effect on recruitment to migration. Reducing natural mortality of fledged juvenile mallards would not have been a feasible means of increasing recruitment. Management strategies that increased nest success, increased brood survival, or decreased hunting mortality would more likely have produced meaningful gains in recruitment and are worthy subjects for continuing study. In northcentral Minnesota, changes in waterfowl habitats, predator populations, and hunting pressure have probably not changed the relative importance of hunting and nonhunting mortality to fledged juvenile mallards since our data were collected.

Zenaida doves are widely hunted, and data on demographic parameters are needed for population management and monitoring. Mean survival rate and mean capture rate per sampling period of hatching-year (HY) and after-hatching-year (AHY) doves did not differ (Ps > 0.10). The standard Jolly-Seber model with time-specific survival and capture rates fit the capture-recapture data (Model A in JOLLY; P > 0.10). There was no difference between the survival and capture rates of newly versus previously captured HY and AHY birds (Ps > 0.10). Survival and capture rates varied by sampling period (Ps < 0.01). For AHY and HY birds combined, mean survival rate per sampling period was 0.84, and mean capture rate was 0.05. Mean population size was 1,451, and mean recruitment rate (births + immigrants) was 591/sampling period. Density of Zenaida doves was 0.97-1.78/ha during 1991-92. Density of nests was 2.44/ha during January-December 1991, 1.69 during April-June 1991, and 1.44 during April-June 1992. Line transect surveys of Zenaida doves and nests were positively correlated (P < 0.01). The number of Zenaida doves and nests was positively correlated with capture-recapture estimates of population size (P < 0.10) and number of fledglings trapped for the first time (P < 0.02). Predator abundance was negatively correlated with number of nests located on the transects (P < 0.01), number of fledglings trapped for the first time (P less than or equal to 0.001), and estimates of recruitment rate (P < 0.05). Overall, mean daily nest survival rate was 0.98, and mean nesting success rate was 0.51; mean number of young fledged per nest was 1.31. Predation caused 88% of nest losses. Zenaida doves are well adapted for multiple brooding and extended nesting, and they are able to compensate for periods of low survival (deaths and emigration) via high recruitment rates (births + immigration).

Compared with a standard design (i.e. one sample per period), this approach (1) permits the estimation of more demographic parameters and (2) in many cases produces more efficient estimators. Program SURVIV is a powerful tool for computing parameter estimates under the robust design. However, multinomial models developed for the robust design require cells for each possible capture history that occurs across the subsamples within a period. This makes the process of entering cell probabilities in SURVIV very tedious and subject to errors. Program RDSURVIV combines SURVIV with a front end that converts capture histories taken under the robust design to the proper input format for estimating parameters under a general model, and builds that model. This model permits Markovian temporary emigration, trap response in capture probabilities and time variation in all parameters. Program RDSURVIV also automatically computes estimates under a series of submodels, but also permits the user to specify other submodels.

Currently it is restricted to seven southeastern states, with most of its breeding range in Florida. Breeding Bird Surveys indicate a declining trend for this Neotropical migrant in most of Florida. Using a rapid survey technique at the Lower Suwannee NWR on 25-27 Mar. 1997, we scanned for kites from 16 sampling stations above the forest canopy, using 10x binoculars for 45 min per station. An effective detection distance of 2.4 km provided almost complete coverage of kite habitat (excluding salt marsh) on the refuge (14,620 ha) and in a 1.6-km buffer (13,526 ha). A mobile observation platform, extended to heights of 30-34 m provided an unobstructed view above the forest canopy where foraging bouts, feeding, courtship displays, and other activities by this species occur. This technique was found to be efficient in obtaining an estimate of potential breeding pairs. An estimated 19 breeding pairs were observed, with possibly five additional pairs, a density of at least one pair per 1173-1407 ha. There was no opportunity to search for nests so we were unable to correlate number of active nests with the number of kites observed, and linear nature of study area might concentrate birds, including nonbreeders, so our density of kites may or may not be typical for other areas. The refuge has a mosaic of 11 different habitats (7 forest types, freshwater and salt marshes, open water and urban/suburban) providing much linear edge to the matrix of different plant communities that range in height from less than 1 m to greater than 30 m. Such structure provides quality habitat for Swallow-tailed Kites.

The South Platte River was enriched in inorganic N (9-800 mu M) derived from municipal wastewater effluent and groundwater return flows from irrigated agricultural fields. River water was as much as 2500% supersaturated with N sub(2)O, and median N sub(2)O emission rates from the river surface ranged from less than 90 to 32 600 mu g-N m super(-2) d super(-1). Seventy-nine percent of the variance in N sub(2)O emission rates was explained by concentrations of total inorganic N in river water and by water temperature. The estimated total annual N sub(2)O emissions from the South Platte River were 2 x 10 super(13)-6 x 10 super(13) mu g-N yr super(-1). This amount of annual N sub(2)O emissions was similar to the estimated annual N sub(2)O emissions from all primary municipal wastewater treatment processes in the United States (1). Results from this study indicate that N-enriched rivers could be important anthropogenic sources of N sub(2)O to the atmosphere. However, N sub(2)O emission measurements from other N-enriched rivers are needed to better quantify this source.

Several colonies of Gull-billed Terns were monitored from May to July each year from 1994 to 1996 on both sandy barrier islands and marsh/shellpile islands in coastal Virginia. Nests were visited one to three times a week to monitor clutch size and hatching success, and enclosures were installed around selected nests to monitor chick growth from hatching to at least two weeks of age. When comparing chick growth, we found significant year, habitat and hatch order effects. Chicks from marsh shellpiles had higher mass and culmen growth rates than did those from barrier islands, and first-hatched chicks had significantly higher culmen growth rates than did second-hatched chicks. Year effects were only found for mass growth rates. Growth rates of Gull-billed Terns in these Virginia colonies seem to be low relative to those of six other North American tern species from other geographic areas. These findings suggest that growth rates of young Gull-billed Terns, as well as other reproductive parameters, need to be examined in detail in other coastal areas such as Texas, where the species is more abundant, to determine whether our growth results are species- or region-specific.

Using band recovery data and reported sightings of patagially marked gulls, we constructed location maps for fledglings, one to two-year-old gulls, and breeding-age adult gulls during five time periods: spring migration, breeding season, early and late fall migration, and winter. Using repeated observations, we also produced a location map with directional vector plots. Gulls followed a triangular pattern of movements. At the conclusion of breeding, gulls migrated west and northwest to the Pacific coast, distributing themselves mainly between San Francisco and British Columbia. During winter, gulls moved south along the Pacific coast and by spring were concentrated in southern California and northern Mexico. The range size was largest among fledglings which provided the northernmost and southernmost observations for the population. Few subadult gulls migrated to the breeding colony. During the breeding season, a substantial portion of breeding-aged adults remained on the Pacific coast and throughout the intermountain west but were not observed at other California gull colonies. While fledglings moved directly toward the Pacific coast at the end of the breeding season, many adults lingered near the colony site and at aquatic habitats south of the colony. We suggest that adults remain longer in the area to feed and to rejuvenate before attempting migration.

Based on the available evidence, a conceptual model of the primary factors controlling species density is presented here. This model suggests that species density is controlled by the effects of disturbance, total community biomass, colonization, the species pool and spatial heterogeneity. The structure of the model leads to two main expectations: (1) while community biomass is important, multivariate approaches will be required to understand patterns of variation in species density, and (2) species density will be more highly correlated with light penetration to the soil surface, than with above-ground biomass, and even less well correlated with plant growth rates (productivity) or habitat fertility. At present, data are insufficient to evaluate the relative importance of the processes controlling species density. Much more work is needed if we are to adequately predict the effects of environmental changes on plant communities and species diversity.

Samples were collected (1992-1997) from above and below the mine drainage source, and further downstream where a historically cleaner tributary enters the system. Hyporheic metal concentrations were high during spring runoff at the impacted site even after initiation of treatment, but declined after several years. Correspondence analysis and increased invertebrate taxa richness suggested that hyporheic macroinvertebrates were recovering at the previously impacted site. Differences in substrate between sites and high water flows in 1995 also appeared to affect hyporheic communities. High taxa richness and abundance, taxa unique from those found at the surface, and high concentrations of metals found in the shallow hyporheic zone suggests that sampling this zone is important for monitoring recovery of polluted streams.

However, there is still uncertainty about the mechanisms through which nutrient enrichment can disrupt biological communities and ecosystem processes in the coastal zone. For example, while some estuaries exhibit classic symptoms of acute eutrophication, including enhanced production of algal biomass, other nutrient-rich estuaries maintain low algal biomass and primary production. This implies that large differences exist among coastal ecosystems in the rates and patterns of nutrient assimilation and cycling. Part of this variability comes from differences among ecosystems in the other resource that can limit algal growth and production - the light energy required for photosynthesis. Complete understanding of the eutrophication process requires consideration of the interacting effects of light and nutrients, including the role of light availability as a regulator of the expression of eutrophication. A simple index of the relative strength of light and nutrient limitation of algal growth can be derived from models that describe growth rate as a function of these resources. This index can then be used as one diagnostic to classify the sensitivity of coastal ecosystems to the harmful effects of eutrophication. Here I illustrate the application of this diagnostic with light and nutrient measurements made in three California estuaries and two Dutch estuaries.

PCB concentrations were determined in lake trout from three different locations in Lake Michigan during 1994-1995, and lake trout diets were analyzed at all three locations. The PCB concentrations were also determined in alewife (Alosa pseudoharengus), rainbow smelt (Osmerus mordax), bloater (Coregonus hoyi), slimy sculpin (Cottus cognatus), and deepwater sculpin (Myoxocephalus thompsoni), five species of prey fish eaten by lake trout in lake Michigan, at three nearshore sites in the lake. Despite the lack of significant differences in the PCB concentrations of alewife, rainbow smelt, bloater, slimy sculpin, and deepwater sculpin from the southeastern nearshore site near Saugatuck (Michigan) compared with the corresponding PCB concentrations from the northwestern nearshore site near Sturgeon Bay (Wisconsin), PCB concentrations in lake trout at Saugatuck were significantly higher than those at Sturgeon Bay. The difference in the lake trout PCB concentrations between Saugatuck and Sturgeon Bay could be explained by diet differences. The diet of lake trout at Saugatuck was more concentrated in PCBs than the diet of Sturgeon Bay lake trout, and therefore lake trout at Saugatuck were more contaminated in PCBs than Sturgeon Bay lake trout. These findings were useful in interpreting the long-term monitoring series for contaminants in lake trout at both Saugatuck and the Wisconsin side of the lake.

Here we present the results of intensive monitoring of sediment discharging from a karst spring in response to two storm events, one following a wet season and the other following a dry season; we describe temporal changes in total suspended solids (TSS), mineralogy, and particle size distribution. Peak concentrations of suspended sediment coincided with changes in aqueous chemistry indicating arrival of surface water, suggesting that much of the discharging sediment had an allochthonous origin. Concentrations of suspended sediment peaked 14-16 h after rainfall, and the bulk of the sediment (approximately 1 metric ton in response to each storm) discharged within 24 h after rainfall. Filtered material included brightly colored fibers and organic matter. Suspended sediments consisted of dolomite, calcite, quartz, and clay. Proportions of each mineral constituent changed as the aquifer response to the storm progressed, indicating varying input from different sediment sources. The hydraulic response of the aquifer to precipitation was well described by changes in parameters obtained from the particle size distribution function, and corresponded to changes seen in TSS and mineralogy. Differences between storms in the quantity and mineralogy of sediment transported suggest that seasonal effects on surface sediment supply may be important. The quantity of sediment discharging and its potential to sorb and transport contaminants indicates that a mobile solid phase should be included in contaminant monitoring and contaminant transport models of karst. Temporal changes in sediment quantity and characteristics and differences between responses to the two storms, however, demonstrate that the process is not easily generalized.

An assessment of cavity availability was needed to determine if the existing nesting box program should be increased. During November to March, 1996-97 and 1997-98, I sampled 56 one-half ha random plots, stratified into 5 types (upland hardwood, upland conifer, upland mixwood, wetland conifer, and wetland hardwood) to assess availability of trees with cavities. The predominant tree species with cavities were red maple (Acer rubrum; 39%) and aspen (Populus sp.; 31%); 72% of all trees with cavities were alive. Density of nest-cavity trees/plot averaged from 1.0 plus or minus 0.4 (x plus or minus SE) in wetland softwoods to 1.9 plus or minus 0.4 in upland hardwoods. This low density of potential cavity trees and the small mean dbh (39.4 plus or minus 1.6 cm ) indicate a young forest with few suitable cavities. Forested areas, especially hardwoods near canopy openings, need to be allowed to mature to increase the number and quality of future cavities. An expanded nest box program seems justified.

All Cistus species were stimulated by brief heat-shock, as shown in previous studies; however, none responded to charred wood. Only one of the 22 species was stimulated by charred wood, and only in dark-inhibited seeds, and this response did not occur in the light. The lack of charred-wood-induced germination is in contrast to the substantial proportion of species with this germination response reported for mediterranean-type vegetation in California, the Cape region of South Africa, and Western Australia. Phrygana has many species with heat-shock-stimulated germination, primarily in the Fabaceae and Cistaceae. This germination cue is widespread in these two families, thus, the presence of heat-shock-stimulated germination is a result of homologous, rather than covergent, adaptations in mediterranean-climate ecosystems. Germination response to light was not randomly distributed with respect to fire-type response. Heat-shock-stimulated species were almost uniformly light neutral, in contrast to more opportunistic colonizing species with non-refractory seeds, in which half of the species responded positively or negatively to light.

However, it is theoretically possible that residual free chlorine in the HCl can react with dissolved organic carbon (DOC) to form chloroform via the haloform reaction. Analyses of 1501 ground water samples preserved with HCl from the U.S. Geological Survey's National Water-Quality Assessment Program indicate that chloroform was the most commonly detected VOC among 60 VOCs monitored. The DOC concentrations were not significantly larger in samples with detectable chloroform than in those with no detectable chloroform, nor was there any correlation between the concentrations of chloroform and DOC. Furthermore, chloroform was detected more frequently in shallow ground water in urban areas (28.5% of the wells sampled) than in agricultural areas (1.6% of the wells sampled), which indicates that its detection was more related to urban land-use activities than to sample acidification. These data provide strong evidence that acidification with HCl does not lead to the production of significant amounts of chloroform in ground water samples. To verify these results, an acidification study was designed to measure the concentrations of all trihalomethanes (THMs) that can form as a result of HCl preservation in ground water samples and to determine if ascorbic acid (C sub(6)H sub(8)O sub(6)) could inhibit this reaction if it did occur. This study showed that no THMs were formed as a result of HCl acidification, and that ascorbic acid had no discernible effect on the concentrations of THMs measured.

Franco)/western hemlock (Tsuga heterophylla (Raf.) Sarg.) stands on 28 sites in western Oregon. These stands had regenerated naturally after timber harvest, 40-70 years before thinning. Commercial thinning had occurred 10-24 years previously, with 8-60% of the volume removed from below with the intent to homogenize spacing among trees. Undisturbed old-growth Douglas-fir stands were present for comparison on 18 of these sites. Total herbaceous cover was greater in thinned (25% cover) stands than in unthinned (13% cover) or old-growth (15% cover) stands. Species richness was also greater in thinned (137) than in unthinned (114) and old-growth (91) stands (P=0.05). Part of the increased richness was caused by the presence of exotic species in thinned stands, but there were also more native grass and nitrogen-fixing species in thinned stands than in unthinned or old-growth stands. Groups of species differed among stand-types. For example, the frequency of tall cordate-leaved species was greater in old-growth stands (P=0.009), but their relative cover was different only between old-growth and unthinned stands (P=0.08). Both the cover and frequency of grasses and sedges in thinned stands were greater than in unthinned or old-growth stands (P less than or equal to 0.002). Ordination of shrub cover showed differences among old-growth and unthinned stands compared to thinned stands, mainly because of the amount of Gaultheria shallon Pursh and Polystichum munitum (Kaulf.) Presl in heavily thinned stands. Ordination of herbaceous community data showed that there were much stronger differences among sites than among stand-types. The lack of difference among stand-types demonstrates the resiliency of herbaceous communities to disturbance associated with past and current forest management.

Intestinal digesta were collected from these species at sympatric overwintering sites in southern California near San Diego to relate sediment ingestion to bill length and feeding behavior. Plover digesta contained an estimated 29% sediment, and Willet digesta an estimated 3% sediment. Techniques based on acid insoluble ash and on the elemental markers of Al, Fe, and Ti in digesta provided similar results. High Ca concentrations in Willet digesta along with our observations suggested that the Willets in our sample fed primarily on molluscs and crustaceans. Sediment ingestion may be species-specific, not necessarily linked to bill length or probing behaviors, and may greatly affect a bird's exposure to environmental contaminants in sediment.

These shifts are expected to be most rapid and extreme at ecotones, the boundaries between ecosystems, particularly those in semiarid landscapes. However, current models do not adequately provide for such rapid effects---particularly those caused by mortality---largely because of the lack of data from field studies. Here we report the most rapid landscape-scale shift of a woody ecotone ever documented: in northern New Mexico in the 1950s, the ecotone between semiarid ponderosa pine forest and pinon-juniper woodland shifted extensively (2 km or more) and rapidly (<5 years) through mortality of ponderosa pines in response to a severe drought. This shift has persisted for 40 years. Forest patches within the shift zone became much more fragmented, and soil erosion greatly accelerated. The rapidity and the complex dynamics of the persistent shift point to the need to represent more accurately these dynamics, especially the mortality factor, in assessments of the effects of climate change.

Using ERS 1 C band ( lambda = 5.66 cm) SAR imagery, we studied the seasonal and temporal changes of the interferometric SAR coherence for fresh lava, weathered lava, tephra with weak water reworking, tephra with strong water reworking, and fluvial deposits representing the range of typical volcanic surface materials in the Katmai volcano group, Alaska. For interferograms based on two passes with 35 days separation taken during the same summer season, we found that coherence increases after early June, reaches a peak between the middle of July and the middle of September, and finally decreases until the middle of November when coherence is completely lost for all five sites. Fresh lava has the highest coherence, followed by either weathered lava or fluvial deposits. These surfaces maintain relatively high levels of coherence for periods up to the length of the summer season. Coherence degrades more rapidly with time for surfaces covered with tephra. For images taken in different summers, only the lavas maintained coherence well enough to provide useful interferometric images, but we found only a small reduction in coherence after the first year for surfaces with lava. Measurement of volcanic deformation is possible using summer images spaced a few years apart, as long as the surface is dominated by lavas. Our studies suggest that in order to make volcanic monitoring feasible along the Aleutian arc or other regions with similar climatic conditions, observation intervals of the satellite with C band SAR should be at least every month from July through September, every week during the late spring/early summer or late fall, and every 2-3 days during the winter.

In contrast, those who manage water resources do not rate climatic change among their top planning and operational concerns. The difference in these views can be associated with how water managers operate their systems and the types of stresses, and the operative time horizons, that affect the Nation's water resources infrastructure. Climate, or more precisely weather, is an important variable in the management of water resources at daily to monthly time scales because water resources systems generally are operated on a daily basis. At decadal to centennial time scales, though, climate is much less important because (1) forecasts, particularly of regional precipitation, are extremely uncertain over such time periods, and (2) the magnitude of effects due to changes in climate on water resources is small relative to changes in other variables such as population, technology, economics, and environmental regulation. Thus, water management agencies find it difficult to justify changing design features or operating rules on the basis of simulated climatic change at the present time, especially given that reservoir-design criteria incorporate considerable buffering capacity for extreme meteorological and hydrological events.

Overall, mean clutch size ranged between 12.5 and 15.1 eggs, mean egg mass per clutch ranged between 10.03 and 11.68 g, and mean relative clutch mass (clutch mass/spent body mass) ranged between 0.079 and 0.097 for nine site-year cohorts. Maternal body size was the most important source of variation in all measures of reproduction because larger females laid larger eggs and larger clutches than smaller females. Reproductive output independent of body size was greater in 1995 than in 1994 or 1996. Clutch size and egg size varied similarly among years at each site. Overall, clutch mass in 1995 was 15.8% and 17.8% greater than clutch mass in 1994 and 1996, respectively. This variation in reproductive output was primarily due to changes in egg number rather than changes in egg size, consistent with theories of egg optimality. Turtles at one site produced relatively small but relatively more eggs per clutch than turtles from the other two sites. This pattern persisted despite varying amounts of energy devoted to reproduction from year to year. However, an egg size-clutch size trade-off could only be weakly demonstrated among nine site-year cohorts. Geographic variation was confirmed for clutch size, which decreased with decreasing latitude, but not for egg mass and plastron length.

Effects of salinity on influx rate were evaluated in these 2 highly euryhaline species as were effects of animal size on uptake and loss. Metal speciation and biological attributes interacted to differentiate bioaccumulation processes among metals and between species. Influx rates of the 3 metals ( mu g g super(-1) [dry wt] d super(-1)) increased linearly with dissolved metal concentrations. Influx rates of Zn in both clams were 3 to 4x those for Cd and 15x those for Cr. However, influx on the basis of free ion activities would be faster for Cd than for Zn. Relative influx rates among the metals were similar in the 2 bivalves. But, absolute influx rates of all 3 metals were 4 to 5x greater in P. amurensis than in M. balthica, probably because of differences in biological attributes (i.e. clearance rate or gill surface area).

Understanding the cumulative structural and site characteristics that affect the response of SCCOB before and after the retrofit is important in assessing earthquake hazards to other similar buildings and decision making in retrofitting them. The results emphasize the need to better evaluate structural and site characteristics in developing earthquake resisting designs that avoid resonating effects. Various studies of the strong-motion response records from the SCCOB during the 24 April 1984 (MHE) Morgan Hill (M sub(s) = 6.1), the 31 March 1986 (MLE) Mt. Lewis (M sub(s) = 6.1) and the 17 October 1989 (LPE) Loma Prieta (M sub(s) = 7.1) earthquakes show that the dynamic characteristics of the building are such that it (a) resonated (b) responded with a beating effect due to close-coupling of its translational and torsional frequencies, and (c) had a long-duration response due to low-damping. During each of these earthquakes, there was considerable contents damage and the occupants felt the rigorous vibration of the building. Ambient tests of SCCOB performed following LPE showed that both translational and torsional periods of the building are smaller than those derived from strong motions. Ambient tests performed following the retrofit of the building with visco-elastic dampers show that the structural fundamental mode frequency of the building has increased. The increased frequency implies a stiffer structure. Strong-motion response of the building during future earthquakes will ultimately validate the effectiveness of the retrofit method.

Natural fluvial islands occur in any part of a drainage network but most commonly in montane, piedmont-valley, and coastal flood-plain environments. Processes, often interactive, by which islands form include avulsion (the sudden separation of land by a flood or by an abrupt change in the course of a stream), rapid and gradual channel incision, channel migration, dissection of both rapidly and slowly deposited bed sediment, and deposition of bed sediment on a vegetated surface or behind a channel obstruction. Products of high-energy conditions, fluvial islands typically lack stability over decades to millennia. Fluvial islands in Plum Creek, Colorado, USA, results of sorting processes following a recent high-magnitude flood, and in the Snake River, Idaho, USA, partly results of the Pleistocene Bonneville Flood, illustrate how islands form, develop, and disappear. The examples consider differing conditions of island shape, size, height, sediment, and vegetation. JF - Wetlands AU - Osterkamp, W R AD - U. S. Geological Survey, 1675 W.

The building is modeled as a layered medium, similar to a layered soil medium, and is subjected to vertically propagating seismic shear waves. Soil layers and the bedrock under the foundation are incorporated in the formulation as additional layers. Seismic response is expressed in terms of the wave travel times between the layers, and the wave reflection and transmission coefficients at the layer interfaces. The equations account for the frequency-dependent filtering effects of the foundation and floor masses. The calculation of seismic response is reduced to a pair of simple finite-difference equations for each layer, which can be solved recursively starting from the bedrock. Compared to the commonly used vibration formulation, the wave propagation formulation provides several advantages, including simplified calculations, better representation of damping, ability to account for the effects of the soil layers under the foundation, and better tools for identification and damage detection from seismic records. Examples presented show the versatility of the method.

Few sampling programs for animal communities provide censuses, and usually some species in surveyed areas are not detected. Thus, counts of species detected underestimate the number of species present. We present estimators useful for drawing inferences about comparative species richness and composition between different sampling locations when not all species are detected in sampling efforts. Based on capture-recapture models using the robust design, our methods estimate relative species richness, proportion of species in one location that are also found in another, and number of species found in one location but not in another. The methods use data on the presence or absence of each species at different sampling occasions (or locations) to estimate the number of species not detected at any occasions (or locations). This approach permits estimation of the number of species in the sampled community and in subsets of the community useful for estimating the fraction of species shared by two communities. We provide an illustration of our estimation methods by comparing bird species richness and composition in two locations sampled by routes of the North American Breeding Bird Survey. In this example analysis, the two locations (and associated bird communities) represented different levels of urbanization. Estimates of relative richness, proportion of shared species, and number of species present on one route but not the other indicated that the route with the smaller fraction of urban area had greater richness and a larger number of species that were not found on the more urban route than vice versa. We developed a software package, COMDYN, for computing estimates based on these methods. Because these estimation methods explicitly deal with sampling in which not all species are detected, we recommend their use for addressing questions about species richness and community composition.

In general, bacteria from the various sites oxidized similar amounts of super(14)CH sub(2)Br sub(2) and comparatively less super(14)CH sub(3)Br. Bacterial oxidation of super(14)CH sub(3)Br was rapid in freshwater samples compared to bacterial oxidation of super(14)CH sub(3)Br in more saline waters. Freshwater was also the only site in which methyl fluoride-sensitive bacteria (e.g., methanotrophs or nitrifiers) governed brominated methane oxidation. Half-life calculations indicated that bacterial oxidation of CH sub(2)Br sub(2) was potentially significant in all of the waters tested. In contrast, only in freshwater was bacterial oxidation of CH sub(3)Br as fast as chemical removal. The values calculated for more saline sites suggested that bacterial oxidation of CH sub(3)Br was relatively slow compared to chemical and physical loss mechanisms. However, enrichment cultures demonstrated that bacteria in seawater can rapidly oxidize brominated methanes. Two distinct cultures of nonmethanotrophic methylotrophs were recovered; one of these cultures was able to utilize CH sub(2)Br sub(2) as a sole carbon source, and the other was able to utilize CH sub(3)Br as a sole carbon source.

The majority of cases have involved benthic or bottom feeding fish living in habitats with sediment contaminated by PAHs. The most common lesions involved in such epizootics include liver neoplasms, both biliary and hepatic, and skin neoplasms. Laboratory research has demonstrated the ability of fish to metabolize carcinogenic PAHs such as B(a)P into the ultimate carcinogen with the resulting formation of DNA adducts. Fish dosed with B(a)P or sediment extracts containing carcinogenic PAHs have developed skin and liver neoplasms. In the Black River, OH, neoplasm prevalence in wild brown bullhead has reflected PAH exposure as the latter has changed due to coke plant closures and remedial dredging activity. The weight of evidence supports a cause-and-effect relationship between exposure to genotoxins in sediment and water and neoplasm epizootics in wild fish populations.

AN - 70000137; 9784310 AB - The potential effects of growth hormone (GH), prolactin (Prl), and triiodothyronine (T3) on gill Na+,K+-ATPase activity and corticosteroid receptor (CR) concentration (Bmax) and dissociation constant (Kd) were examined in juvenile Atlantic salmon (Salmo salar). Compared to controls, fish injected with GH (ovine, 5.0 microgram g-1) had significantly greater gill Na+,K+-ATPase activity after 7 and 14 days. Gill CR Bmax and Kd were significantly elevated on day 7, but not day 14. T3 also significantly increased CR Bmax. The effect of GH on CR Bmax was also additive with T3 (5.0 microgram g-1) treatment. There was a synergistic effect on CR Bmax when purified coho salmon GH (csGH, 0.1 microgram g-1) was injected in combination with T3 (1.6 microgram g-1). Prl (ovine, 5.0 microgram g-1; purified coho salmon, 0.1 microgram g-1) did not significantly alter gill CR Bmax. Although Prl limited the increase in CR Bmax by GH, the effect was not signicant. T3 and Prl did not have an effect on Kd. GH significantly increased gill Na+,K+-ATPase activity, T3 administration did not have a significant effect, and Prl-treated fish had significantly lower gill Na+,K+-ATPase activity. The results indicate that T3 acts additively with GH, while Prl has no effect in regulating CR Bmax.

AN - 18332476; 4468628 AB - Profile development indices for soils developed in moraines and outwash near Twin Lakes and in outwash near Leadville support the correlation of moraines with subdued morphology and two high outwash terraces with the Bull Lake glaciation (ca. 130-160 ka) and the correlation of hummocky moraines and two low outwash terraces with the Pinedale glaciation (ca. 14-47 ka). Elsewhere in the northern part of the upper Arkansas Valley, glacial sequences are correlated by mapping outwash terraces near the mouths of major tributaries of the Arkansas River. Near Twin Lakes, indices for soils on low, outer lateral moraines suggest that the older Pinedale glaciers extended beyond the margin of high, younger Pinedale lateral moraines with hummocky topography. A few subdued moraines near Twin Lakes and Leadville probably record one or more glaciations significantly older than the Bull Lake. The downvalley extent of Pinedale glaciers in the Mosquito Range on the east side of the Arkansas Valley is uncertain: most likely, Pinedale glaciers were almost as extensive as Bull Lake glaciers but built no prominent terminal moraines at their maximum positions.

DFM was found to be a reversible inhibitor of CH sub(4) oxidation by Methylococcus capsulatus (Bath). Consumption of CH sub(4) in soil was blocked by additions of low levels of DFM (0.03 kPa), and this inhibition was reversed by DFM removal. Although a small quantity of DFM was consumed during these incubations, its remaining concentration was sufficiently elevated to sustain inhibition. Methanogenesis in anaerobic soil slurries, including acetoclastic methanogenesis, was unaffected by levels of DFM which inhibit methanotrophy. Low levels of DFM (0.03 kPa) also inhibited nitrification and N sub(2)O production by soils. DFM is proposed as an improved inhibitor of CH sub(4) oxidation over acetylene and/or methyl fluoride on the basis of its reversibility, its efficacy at low concentrations, its lack of inhibition of methanogenesis, and its low cost.

The standard dichotomous choice contingent valuation model estimated a value of $268 per household, which was compared to values ranging from $50 to $330, depending on how respondent uncertainty was explicitly incorporated into the dichotomous choice model. For this data set, incorporating respondent uncertainty had the effect of increasing the goodness of fit and decreasing the standard error of estimated willingness to pay in only one of five models tested.

Ultrasonic telemetry was used to track seventeen control and eight anosmic silver eels through 32 km of the Penobscot Estuary, Maine, U.S.A. Twelve of seventeen control eels migrated out of the estuary in 97 h (approximately 4 d) on average. Only two of eight anosmic eels migrated out of the estuary. On average these two anosmic eels migrated out of the estuary within 180 h (approximately 7.5 d) of release and the other six had not left within 9 d. Most control eels progressed rapidly to the mouth of the estuary within a few days. Anosmic eels spent more time in the estuary and demonstrated different behavior from control eels due to their lack of olfaction. Some control eels moved with the appropriate tide, the ebb tide for transport out of the estuary, within one tidal cycle of being released into tidal freshwater. However, anosmic eels either did not move with the appropriate tide or took significantly longer to do so. Olfaction was probably used for orientation by control eels sensing chemical clues (organic and inorganic), which change throughout the tidal cycle. Increased migration times and errors in orientation were likely related to the inability of anosmic eels to use selective tidal stream transport for movement out of the estuary. Chemical clues seem to be one of the most important environmental clues used to guide estuarine migration of silver eels. However, a hierarchy of sensory mechanisms and environmental clues are most likely used for estuarine orientation.

They examined Christmas Bird Count (CBC) data from Southeast Alaska, and concluded there is no evidence for declines in populations. They suggested that our previous analysis of CBC data for murrelets was erroneous, and suggested that "the disparity between our conclusions ... invites explanation". Invitation accepted. In the following, I will show that there was no disparity in conclusions, that Hayward and Iverson mis-represented our conclusions and they conducted a highly selective review of evidence for murrelet population changes in Alaska. The result was a paper that was inaccurate, incomplete, out-of-date, mis-leading and of little service to the readers of Northwest Science who might have read their article hoping to gain some new insight on the status of marbled murrelets in Alaska.

Response to heterospecific alarm cues has been demonstrated for tadpoles within but not among taxa and alarm response behavior has seldom been examined under field conditions. This study examined the response of three sympatric amphibian larvae and predaceous larval Dytiscus sp. (diving beetle) to damage-release signals in natural ponds by using capture rates from treated funnel traps as an index of larval behavior. Hyla regilla (Pacific tree frog) tadpoles avoided traps treated with either crushed conspecifics or with Rana aurora (red-legged frog) tadpoles but the larger ranids and Ambystoma macrodactylum (long-toed salamander) did not respond to either treatment. H. regilla tadpoles were likely susceptible to any potential predators of ranid tadpoles in these ponds and this result is consistent with the hypothesis that a response to heterospecific alarm occurs in sympatric prey with shared predators.

The border region overlies a vast area of diverse landscapes and cultures, contrasting some of North America's most pristine and untouched ecosystems with some of its fastest growing urban areas. This region encompasses a wide array of physical settings and habitats, including freshwater and marine wetlands, deserts, rangelands, mountains, and forests, that are unique in terms of the diversity of their water, mineral, and biological resources. Politically, the border area includes four States in the United States (California, Arizona, New Mexico, and Texas) and six States in Mexico (Baja California Norte, Sonora, Chihuahua, Coahuila, Nuevo Leon, and Tamaulipas). There are 14 major sister-city pairs along the border, and the 200-kilometre-wide border region is home to more than 10 million people, a tenfold increase during the past 60 years. The socio-political culture that has developed in the region is truly unique, and the natural resource and environmental issues freely affect the entire area. A wide array of federal, state, local, and tribal entities in both countries are responsible for the management of the border's natural and cultural transboundary resources. Among these valued resources are (1) numerous national monuments, forests, and wildlife refuges; (2) biosphere reserves; (3) several state and national parks; (4) a national seashore; and (5) a designated wild and scenic river.

AN - 17162484; 4470094 AB - We located 511 Acadian Flycatcher (Empidonax virescens) nests in bottomland hardwood forest of eastern Arkansas. Microhabitat characteristics were measured and their relationship with nest success evaluated. Fifty-two percent of all nesting attempts resulted in predation. Attributes of nest placement were similar between successful and unsuccessful nests, although successful nests were placed higher. Similarly, nonparasitized nests were typically higher than parasitized nests. Nests initiated late in the breeding season were placed in larger trees with higher canopy bases resulting in increased vegetation around the nest. Fifteen different tree species were used for nesting. Acadian Flycatchers chose nest trees in a nonrandom fashion, selecting Nuttall oak (Quercus nuttallii) and possumhaw (Ilex decidua) in greater proportions than their availability. However, there was no relationship between tree species used for nesting and nest success. Nest height was positively correlated with concealment at the nest site, supporting the predator-avoidance theory. No other attribute of nest placement differentiated successful nest sites, suggesting that nest predation is likely a function of random events in space and time.

The proportion of alien species relative to the total species number and to canopy cover in the ground stratum (0-0.6 m height) was evaluated in 279 plots. Visually evident anthropogenic disturbances (e.g., artificial regeneration, logging, prescribed burning, and grazing by livestock), if any, were recorded on each plot. In each of the seven regions we quantified (1) the percentage of the number of species and total cover comprised of alien species, (2) the difference in these percentages for disturbed and undisturbed plots, and (3) the origin or native range for the alien species. The percentage of alien species ranged from approximately 4.5% (Colorado) to approximately 13.2% (California). The percentage of alien species cover ranged from approximately 1.5% in Colorado to 25% in California. In five regions, species introduced from temperate Eurasia comprised the largest proportion of alien species and cover. In the Southeast, species introduced from far eastern and subtropical Asia dominated the alien flora. In the Mid-Atlantic, the majority of alien species was Eurasian and the majority of alien species cover consisted of far eastern and subtropical Asian species. The proportion of plots in which at least one alien species was recorded was significantly higher in disturbed than undisturbed plots in the Southeast and marginally significantly higher (p = 0.053) in the Northeast. These results are consistent with other published studies that indicate that anthropogenic disturbance affects the structure and composition of both the ground stratum and upper canopy of forest habitats. In other regions, however, no significant differences were found.

We used Monte Carlo methods to compare 11 such estimators, across a range of community structures and sampling regimes, and validated our results, where possible, using empirical data from vascular plant and beetle inventories from Glacier National Park, Montana, USA. We found that B. Efron and R. Thisted's 1976 negative binomial estimator was most robust to differences in community structure and that it was among the most accurate estimators when sampling was from model communities with structures resembling the large, heterogeneous communities that are the likely targets of major inventory efforts. Other estimators may be preferred under specific conditions, however. For example, when sampling was from model communities with highly even species-abundance distributions, estimates based on the Michaelis-Menten model were most accurate; when sampling was from moderately even model communities with S = 10 species or communities with highly uneven species-abundance distributions, estimates based on Gleason's (1922) species-area model were most accurate. We suggest that use of such methods in species inventories can help improve cost-effectiveness by providing an objective basis for redirecting sampling to more-productive sites, methods, or time periods as the expectation of detecting additional species becomes unacceptably low.

We used monthly data from a 1991-1996 study of debris on a New Jersey beach to determine if indicator and non-indicator items showed similar trends. Total indicator debris levels did not change; this was true regardless of probable source. Non-indicator debris increased about 40% annually. Plastic non-indicator items increased regardless of whether items were whole items, cigarette filters, or pieces. Of the whole items, almost 50% were plastic lids, cups, and utensils, and about 25% were drug-related paraphernalia, tobacco-related products, plastic stirrers, pull rings, and fireworks. When indicator items are used in a monitoring programme to reflect total debris patterns, concordance of trends in indicator and non-indicator debris should be checked.

The sinks occur in alluvial deposits along the flood plain of the Santa Cruz River, and have made farmlands dangerous and unsuitable for farming. More than 1700 sinks are confined to the flood plain of the Santa Cruz River and are grouped along two north-northwestward-trending bands that are approximately parallel to the river and other flood-plain drainages. An estimated 17,000m super(3) of sediment have been removed in the formation of the sinks. Thirteen trenches were dug to depths of 4-6m to characterize near-surface sediments in sink and nonsink areas. Sediments below about 2m included a large percentage of dispersive clays in sink areas. Sediments in nonsink areas contain a large component of medium- to coarse-grained, moderately to well sorted sand that probably fills a paleochannel. Electromagnetic surveys support the association of silts and clays in sink areas that are highly electrically conductive relative to sand in nonsink areas. Sinks probably are caused by the near-surface process of subsurface erosion of dispersive sediments along pre-existing cracks in predominantly silt and clay sediments. The pre-existing cracks probably result from desiccation or tension that developed during periods of water-table decline and channel incision during the past 100 years or in earlier periods.Original Abstract: Des effondrements en forme d'entonnoir se sont produits sur et pres d'exploitations agricoles de Pima (Arizona). Ces entonnoirs apparaissent dans les alluvions le long de la plaine d'inondation de la riviere Santa Cruz ; ils ont rendu ces terrains dangereux et inexploitables pour l'agriculture. Plus de 1700 entonnoirs existent dans la plaine d'inondation de la riviere Santa Cruz et sont groupes en deux bandes orientees nord-nord-ouest, approximativement paralleles a la riviere et aux autres chenaux de la plaine d'inondation. Un volume de sediments estimea 17,000m super(3) a ete entraine lors de la formation de ces entonnoirs. Treize tranchees ont ete creusees a des profondeurs de 4 a 6m afin de caracteriser les sediments proches de la surface dans les zones avec et sans entonnoirs. Les sediments situes a 2m environ sous la surface contiennent un fort pourcentage d'argile dispersee, dans les zones a entonnoirs. Dans les zones sans entonnoirs, la granulometrie des sediments est constituee en fortes proportions de sables moyens a grossiers, moyennement a bien lites, qui remplissent probablement un ancien chenal. Des leves electromagnetiques montrent que l'association de silts et d'argiles dans les zones a entonnoirs possede une forte conductiviteelectrique, par comparaison avec les sables des zones sans entonnoirs. Les entonnoirs sont dus probablement a des processus, proches de la surface, d'erosion souterraine des sediments constitues surtout de silts et d'argiles. Les fractures preexistantes resultent sans doute de la dessiccation ou de la tension se produisant lors des periodes d'abaissement de la nappe, liea l'enfoncement du lit de la riviere au cours des cent dernieres annees ou meme avant. super(1) JF - Hydrogeology Journal AU - Hoffmann, John P AU - Pool, Donald R AU - Konieczki, AD AU - Carpenter, Michael C AD - US Geological Survey, Water Resources Division 520 N.

Audio-magnetotellurics (AMT) measurements at 77 sites in the study area yielded electrical-resistivity logs of the subsurface, and these were used to infer lithologic changes with depth. A 100-600ohm-m geoelectric layer, designated the Jackson aquifer, was used to represent surficial saturated, unconsolidated deposits of Quaternary age. The median depth of the base of the Jackson aquifer is estimated to be 200ft (61m), based on 62 sites that had sufficient resistivity data. AMT-measured values were kriged to predict the depth to the base of the aquifer throughout the southern part of Jackson Hole. Contour maps of the kriging predictions indicate that the depth of the base of the Jackson aquifer is shallow in the central part of the study area near the East and West Gros Ventre Buttes, deeper in the west near the Teton fault system, and shallow at the southern edge of Jackson Hole. Predicted, contoured depths range from 100ft (30m) in the south, near the confluences of Spring Creek and Flat Creek with the Snake River, to 700ft (210m) in the west, near the town of Wilson, Wyoming.Original Abstract: Une campagne geophysique a ete entreprise pour preciser la profondeur du mur de l'aquifere dans le secteur sud de Jackson Hole (Wyoming, Etats-Unis). Des mesures audio-magnetotelluriques (audio MT) sur 77 sites de ce secteur ont fourni des logs de resistiviteelectrique du sous-sol ; les variations de la lithologie en fonction de la profondeur en ont ete deduites. Un niveau geoelectrique a 100-600ohm.m, denomme QUOTATION_MARKaquifere de JacksonQUOTATION_MARK, a servi a definir des depots superficiels quaternaires satures en eau et non consolides. La profondeur mediane de la base de l'aquifere de Jackson est de l'ordre de 61m, a partir des 62 sites ayant fourni suffisamment de donnees de resistivite. Les valeurs audio MT mesurees ont ete krigees afin d'estimer la profondeur de la base de la formation aquifere dans la partie sud de Jackson Hole. Les cartes d'isovaleurs d'estimation krigees indiquent que la profondeur de la base de la formation aquifere de Jackson est faible dans la partie centrale de la zone d'etude a l'est et a l'ouest des monts Gros Ventre, plus grande dans le secteur ouest pres de la zone faillee de Teton, et faible sur la bordure sud de Jackson Hole. Les profondeurs estimees vont de 30m au sud, pres des confluences des rivieres Spring et Flat avec la riviere Snake, a 210m a l'ouest pres de la ville de Wilson (Wyoming).

The Ghyben-Herzberg relation, which is commonly used to estimate interface depth, can greatly underestimate or overestimate the fresh-water thickness, because it assumes no vertical head gradients and no vertical flow. Estimation of the interface depth needs to consider the vertical head gradients and aquifer anisotropy that may be present. This paper presents a method to calculate vertical head gradients using water-level measurements made during drilling of a partially penetrating well; the gradient is then used to estimate interface depth. Application of the method to a numerically simulated fresh-water/salt-water system shows that the method is most accurate when the gradient is measured in a deeply penetrating well. Even using a shallow well, the method more accurately estimates the interface position than does the Ghyben-Herzberg relation where substantial vertical head gradients exist. Application of the method to field data shows that drilling, collection methods of water-level data, and aquifer inhomogeneities can cause difficulties, but the effects of these difficulties can be minimized.Original Abstract: Une estimation precise de la profondeur de l'interface theorique entre l'eau douce et l'eau salee est un element critique dans les estimations de rendement des puits dans les aquiferes insulaires et littoraux. La relation de Ghyben-Herzberg, qui est habituellement utilisee pour estimer la profondeur de cette interface, peut fortement sous-estimer ou surestimer l'epaisseur de l'eau douce, parce qu'elle suppose l'absence de gradient vertical de charge et d'ecoulement vertical. L'estimation de la profondeur de l'interface requiert de prendre en consideration les gradients verticaux de charge et l'eventuelle anisotropie de l'aquifere. Cet article propose une methode de calcul des gradients verticaux de charge a partir des mesures de niveau piezometrique faites en cours de foration d'un puits incomplet; le gradient est alors utilise pour estimer la profondeur de l'interface. L'application de cette methode a un systeme eau douce - eau salee simule numeriquement montre que la methode est la plus precise lorsque le gradient est mesure dans un puits penetrant profondement dans l'aquifere. Meme en utilisant un puits peu profond, la methode estime la position de l'interface avec plus de precision que ne le fait la relation de Ghyben-Herzberg lorsqu'il existe un gradient vertical de charge bien marque. L'application de la methode a des donnees de terrain montre que la foration, les methodes de mesure de niveau et les heterogeneites au sein de l'aquifere peuvent etre la cause de difficultes, mais que les effets de ces difficultes peuvent etre reduits.

AN - 70059711; 9827057 AB - We investigated the regulation of the muscarinic cholinergic receptor (MChR) in brain from seven species of fish, two surrogates and five threatened or endangered species exposed to a series of chemicals as a measure of compensatory response among species. Fish were classified as either cold water (rainbow trout-surrogate, apache trout, lahanton trout) or warm water (fathead minnow-surrogate, razorback sucker, bonytail chub, colorado squawfish) and were exposed to chemicals shown to affect cholinergic pathways (carbaryl and permethrin) and two chemicals whose relationships to the cholinergic system is less clear (4-nonylphenol and copper). Downregulation of MChR occurred in all warm water species, except colorado squawfish, and at carbaryl concentrations similar to those causing downregulation observed in rainbow trout. Permethrin exposure resulted in downregulation in fathead minnow and razorback sucker, but the concentrations required for observation of this phenomenon were much greater than observed in cold water species. Copper exposure caused a decrease in brain MChR in rainbow trout and apache trout, whereas 4-nonylphenol exposure resulted in a decrease in brain MChR in all three cold water species. Our results indicate that surrogates are useful in assessing sublethal physiological responses to chemicals with a known mechanism of action such as carbaryl and support use of surrogates for assessing physiological responses to chemicals with diverse, less clear mechanisms of action.

AN - 70054925; 9813844 AB - An enzyme-linked immunosorbent assay (ELISA) was developed for the detection of type C botulinum toxin (Clostridium botulinum) in wild birds. This simple, antigen-capture ELISA utilizes polystyrene immunosticks as the solid substrate, chicken antitoxin (IgY) as the coating antibody, rabbit antitoxin as the primary antibody, and peroxidase-labeled goat-anti-rabbit as the secondary antibody. To evaluate the immunostick ELISA as a diagnostic test for avian botulism, known concentrations of toxin were added to heparinized blood collected from healthy birds and tested by both the ELISA and mouse bioassay. Also, blood samples from 236 bird carcasses submitted to the National Wildlife Health Center (NWHC) for cause of death determinations were tested by both procedures. Using or = 1.0 ml), the sensitivity of the ELISA may be equivalent or better than the mouse test due to the concentrating effect of the ELISA procedure. These preliminary results suggest that when adequate sample volumes are available, the immunostick ELISA can replace the mouse test for the diagnosis of botulism in wild birds.

The erosive potential of the jet is related to the energy of impact and the rate of energy dissipation in the plunge pool. A method was sought to predict the velocity decay of a free-falling, highly turbulent, rectangular jet in a plunge pool. Two types of jets were evaluated: a highly turbulent, fully air entrained developed jet; and a highly turbulent, nonaerated undeveloped jet. A model of a plunging jet was constructed to simulate these free-falling, highly turbulent rectangular jets. Data were collected from 14 tests, from which empirical equations were derived for the two jet classifications to predict jet velocity decay through the plunge pool. The jet velocity decay was determined to be a function of jet impact velocity with the plunge pool surface, jet density at impact with the plunge pool surface, the density of the water, gravity, and plunge depth.

Thirteen of 18 emergences examined were preceded by individual rains with total rainfall exceeding thresholds (25 mm during autumn [21 September-10 December] or 50 mm during winter-early spring [11 December-10 April]) stimulating plant development, and this proportion was higher than expected compared with the historical occurrence of similar high-rainfall events. The remaining five emergences were preceded by individual rains associated with plant growth during spring being variable or absent. Emergence by O. clara adults coincident with physiological development by desert shrubs may directly or indirectly provide soil-inhabiting larval offspring with a food supply of required abundance and quality.

Use of the federally owned San Luis Drain was made contingent on the formation of a regional drainage management authority by the project proponents and compliance with strict monthly and annual selenium-load targets and agreement to strict monthly and annual selenium-load targets for discharges from the 97,000-acre (44,000 hectares) project area. During the first year of this 5-year project, the Grasslands Basin farmers were successful in reducing selenium export from the project area by 44% and 33% when compared to water years 1995 and 1996. Although monthly targets were exceeded during the spring months of 1997, in part due to unusually high rainfall runoff from the project area and upper watershed, the goals of the project were met. There is popular sentiment that more was learned about selenium drainage management and achieved in selenium load reductions by participating water districts during the first year of the project than in the past decade.

Insecticide exposure AN - 17261504; 4558505 AB - A study of organophosphorus (OP) insecticide exposure was conducted on a declining population of ring-necked pheasants (Phasianus colchicus) associated with agricultural lands at Tule Lake National Wildlife Refuge (TLNWR) during the summers of 1990-92. Findings at TLNWR were compared with a nearby pheasant population at Lower Klamath National Wildlife Refuge (LKNWR) not subjected to intensive farming or OP insecticide applications. Direct toxicity of anticholinesterase (antiChE) compounds (in this case methamidophos) killed 2 young pheasants (91 and 92% brain acetylcholinesterase [AChE] inhibition), but no deaths of adult radio-equipped hens were ascribed to direct insecticide intoxication. However, within 20 days postspray of OP insecticides, 68% (28 of 41) of the adult pheasants collected at TLNWR were exposed to antiChE insecticides, and exhibited brain AChE inhibition of 19-62%, with 15% (6 of 41) showing less than or equal to 55% brain AChE inhibition. The lack of radio-equipped hens dying was unexpected because >50% brain AChE inhibition has been frequently used as a `diagnostic tool' for evaluating cause of death from antiChE insecticides. No young were radio-equipped, so the extent of the effects of insecticide exposure on the survivorship of young was unknown. It is concluded that insecticide exposure was not the major factor impacting the pheasant population (see Grove et al., in press), although some young were acutely intoxicated. However, the loss of insects killed by insecticide use may have contributed to food shortages of young pheasants, indirectly influencing survival.

From 1993 through 1996, we monitored breeding numbers of Gull-billed Terns and their frequent colony associates, Common Terns (Sterna hirundo) and Black Skimmers (Rynchops niger), at colony sites along 80 km of the barrier island region of coastal Virginia. We also monitored flooding events and renesting. We developed the model for colony survival, extinction, and recolonization at potential colony sites over the four-year period. We then used data on annual site occupation by Gull-billed Terns to estimate model parameters and tested for differences between nesting substrates (barrier island vs. shellpile). Results revealed a dynamic system but provided no evidence that the dynamics were Markovian, i.e. the probability that a site was occupied in one year was not influenced by whether it had been occupied in the previous year. Nor did colony-level reproductive success the previous season seem to affect the probability of site occupancy. Site survival and recolonization rates were similar, and the estimated overall annual probability of a site being occupied was 0.59. Of the 25 sites that were used during the four-year period, 16 were used in one or two years only, and only three were used in all four years. Flooding and renesting were frequent in both habitat types in all years. The frequent flooding of nests on shellpiles argues for more effective management; augmentation with shell and sand to increase elevations as little as 20 cm could have reduced flooding at a number of sites. The low colony-site fidelity that we observed suggests that an effective management approach would be to provide a large number of sand and/or shellpile sites for use by nesting terns. Sites not used in one year may still be used in subsequent years.

It can be due to improper agricultural practices, livestock grazing, mining, fire management, recreation practices, deforestation, urbanization, and introduction of exotic species. Thus, national, state, and local policies must deal with a wide range of circumstances and land uses, and they must be comprehensive and dynamic, providing flexibility as issues, knowledge, and needs change. The United States can demonstrate many causations, but also successes, in combating desertification. However, much more work is needed to assure sustainable use of millions of hectares, particularly in the drylands of the western United States. A vigilance on policies and their implementation is required to assure that efforts to combat desertification are effective. Over time, some policies outlive their purpose and require change, but that is not always easy to achieve, and many times it takes a concentrated effort over several years or more to bring about, especially if that policy has its basis in law. Although this process sometimes seems slow, new laws continue to be enacted and policies are adopted that address land uses and the difficult task of combating desertification. Several examples are offered to show the variety of actions taken and processes used in the United States.

Adult sculpin spawned in shallow water (0.5-6.0 m depths) in cavities beneath large cobbles and boulders. During 1993, egg mass densities were highest (> 4.0 m super(2)) at 1.0-2.0 m depths. Electivity indices verified substrate selection and also indicated an avoidance of sand- and gravel-embedded materials. During years of low water elevation, suitable spawning substrates were restricted to one or two limited areas of the lake and comprised < 0.004% of the total benthic area. Disturbance from turbulence, as would be produced by storm-induced waves, appeared to initiate hatching. After hatching, embryos passed through a pelagic interval that lasted for approximately one week. Laboratory experiments confirmed the short duration of this surface-swimming behavior. The pelagic behavior of free embryos appears to aid in dispersal of fish Via currents from limited spawning habitats to areas throughout the 282 km super(2) lake.

However, statistical properties of scent-station data are poorly understood, and the relation between scent-station indices and carnivore abundance has not been adequately evaluated. We assessed properties of scent-station indices by analyzing data collected in Minnesota during 1986-93. Visits to stations separated by <2 km were correlated for all species because individual carnivores sometimes visited several stations in succession. Thus, visits to stations had an intractable statistical distribution. Dichotomizing results for lines of 10 stations (0 or greater than or equal to 1 visits) produced binomially distributed data that were robust to multiple visits by individuals. We abandoned 2-way comparisons among years in favor of tests for population trend, which are less susceptible to bias, and analyzed results separately for biogeographic sections of Minnesota because trends differed among sections. Before drawing inferences about carnivore population trends, we reevaluated published validation experiments. Results implicated low statistical power and confounding as possible explanations for equivocal or conflicting results of validation efforts. Long-term trends in visitation rates probably reflect real changes in populations, but poor spatial and temporal resolution, susceptibility to confounding, and low statistical power limit the usefulness of this survey method.

We used radiotelemetry techniques to examine the magnitude and causes of mortality of swift fox populations in 2 study areas in western Kansas. One study area was predominantly cropland, the other rangeland. Mortality rates, calculated using Kaplan-Meier estimation techniques in a staggered entry design, were 0.55 plus or minus 0.08 for adult and 0.67 plus or minus 0.08 for juvenile swift foxes. We did not detect differences between study areas in mortality rates for adults or juveniles. Predation by coyotes (Canis latrans) was the major cause of mortality for adult and juvenile swift foxes in both study areas, and vehicle collision was an important mortality factor for juveniles in the cropland study area. No mortality was attributed to starvation or disease.

Because pintails show high fidelity to wintering areas, regional survival estimates and identification of factors influencing survival are needed to guide management of wintering pintails. We used radiotelemetry to estimate survival rates of female pintails wintering in southwestern Louisiana. We tested for variation in survival and hunting mortality rates in relation to age (immature or adult), winter (1990-91, 1991-92, 1992-93), time period (prehunting season, first hunting season, time between split hunting seasons, second hunting season, posthunting season), body condition (body mass when released, adjusted for body size), and region (southwestern Louisiana or elsewhere on the Texas-Louisiana Gulf Coast or Mississippi Alluvial Valley). Within southwestern Louisiana, the 147-day (5 Oct-28 Feb) survival rate of adults (0.714 plus or minus 0.045) was greater (P = 0.02) than that of immatures (0.550 plus or minus 0.068), primarily because immatures had higher hunting mortality. Female survival was lower (Ps 0.25). Survival did not differ in relation to winter or condition (Ps > 0.12). Hunting mortality did not differ (Ps > 0.13) in relation to winter, condition, or region, but hunting mortality of immatures (0.287 plus or minus 0.046) was greater (P < 0.001) than that of adults (0.130 plus or minus 0.025). Despite conservative hunting regulations (30-day seasons and 1 pintail daily), hunting mortality rates of pintails in southwestern Louisiana were high. Pintails in southwestern Louisiana rely on a small number of key refuges for protection but feed almost exclusively in privately owned agricultural fields. If increased winter survival of female pintails in southwestern Louisiana is desired, we recommend that managers increase food availability on refuges.

Caribou in Denali differed from other cervid populations where reproductive performance has been investigated, because they occur at low densities ( less than or equal to 0.3/km super(2)) and experience high losses of young to predation. Females first gave birth at 2-6 years old; 56% of these females were 3 years old. Average annual natality rates increased from 27% for 2-year-olds to 100% for 7-year-olds, remained high for 7-13-year-olds (98%), and then declined for females greater than or equal to 14 years old. Females greater than or equal to 2 years old that failed to reproduce were primarily sexually immature (76%). Reproductive pauses of sexually mature females occurred predominantly in young (3-6 yr old) and old ( greater than or equal to 14 yr old) females. Natality increased with body mass for 10-month-old females weighed 6 months prior to the autumn breeding season (P = 0.007), and for females >1 year old and weighed during autumn (late Sep-early Nov; P = 0.003). Natality for 2-, 3-, 4-, and 6-year-olds declined with increasing late-winter snowfall (Feb-May; P less than or equal to 0.039) during the winter prior to breeding. In most years, a high percentage of sexually mature females reproduced, and lactation status at the time of breeding did not influence productivity the following year. However, following particularly high snowfall during February-September 1992, productivity was reduced in 1993 for cows successfully rearing calves to autumn the previous year. High losses of calves to predators in 1992 may have increased productivity in 1993. Losses of young-of-the-year to predation prior to the annual breeding season can be an important influence on subsequent productivity for ungulate populations where productivity varies with lactation status of females at the time of breeding.

However, managers of bison (Bison bison) herds have not been able to use this aging technique, because a correlation between the cementum age and the known age of an animal has never been established. This paper presents the results of a study designed to fill that void and establish whether bison can be aged accurately by the number of incremental growth bands present in the roots of their teeth. The results indicate bison do produce regular cementum annuli in the roots of teeth that correspond accurately with age.

Hepatic cytochrome P450 enzyme activity in pipped embryos of Forster's terns from the two colonies seemed unaffected by contaminants. At Crescent Island, examination of 23 Forster's tern eggs with large embryos (19 viable [10 pipped] and four dead [two pipped]) revealed developmental abnormalities in two viable pipped embryos (missing maxilla and deformed pelvic girdle) and a viable prepipping embryo (shortened beak). Our limited sample sizes and number of compounds analyzed preclude us from determining whether or not the abnormalities are related to contaminants. No abnormalities were noted in 10 pipped eggs (nine viable and one dead at collection) of Forster's terns collected from the Potholes Reservoir colony. Eggs of Caspian terns (Sterna caspia) collected from Crescent Island in 1991 also contained generally low residues of contaminants, only one developmental abnormality was noted, and limited data indicated that cytochrome P450 enzyme activity apparently was unaffected by contaminants. Organochlorine contaminants were generally low in addled eggs of American white pelicans (Pelecanus erythrorhynchos) collected from Crescent Island in 1994.

We used 25 years of bird checklist data from the Etudes des Populations d'Oiseaux du Quebec program to examine the ability of checklists to produce reliable conservation, management, and ecological information. We found that checklists can provide reliable information on changes in bird populations, phenology, and geographic and climate abundance patterns at local, regional, and continental scales. Professional and amateur conservation groups that need to develop extensive monitoring programs should take advantage of the fact that checklists, unlike other time-consuming and expensive techniques, can be used to detect large-scale changes in an entire community of species.

Heat shock triggers germination of certain species but has no stimulatory effect on a great many other postfire species that are chemically stimulated by combustion products. Previous reports have shown that charred wood will induce germination, and here we report that smoke also induces germination in these same species. Smoke is highly effective, often inducing 100% germination in deeply dormant seed populations with 0% control germination. Smoke induces germination both directly and indirectly by aqueous or gaseous transfer from soil to seeds. Neither nitrate nor ammonium ions were effective in stimulating germination of smoke-stimulated species, nor were most of the quantitatively important gases generated by biomass smoke. Nitrogen dioxide, however, was very effective at inducing germination in Caulanthus heterophyllus (Brassicaceae), Emmenanthe penduliflora (Hydrophyllaceae), Phacelia grandiflora (Hydrophyllaceae), and Silene multinervia (Caryophyllaceae). Three species, Dendromecon rigida (Papaveraceae), Dicentra chrysantha, and Trichostema lanatum (Lamiaceae), failed to germinate unless smoke treatment was coupled with prior treatment of 1 yr soil storage. Smoke-stimulated germination was found in 25 chaparral species, representing 11 families, none of which were families known for heat-shock-stimulated germination. Seeds of smoke-stimulated species have many analogous characteristics that separate them from most heat-shock-stimulated seeds, including: (1) outer seed coats that are highly textured, (2) a poorly developed outer cuticle, (3) absence of a dense palisade tissue in the seed coat, and (4) a subdermal membrane that is semipermeable, allowing water passage but blocking entry of large (molecular mass > 500) solutes. Tentative evidence suggests that permeability characteristics of this subdermal layer are altered by smoke. While the mechanism behind smoke-induced germination is not known, it appears that smoke may be involved in overcoming different blocks to germination in different species. For example, in Emmenanthe penduliflora, NO sub(2) in smoke was sufficient to induce germination, and most forms of physical or chemical scarification also induced germination. For Romneya coulteri, NO sub(2) alone failed to induce germination, and scarified seeds required addition of gibberellic acid. In Dicentra chrysantha, none of these treatments, nor smoke alone, induced germination, but germination was triggered by a combination of soil burial followed by smoke treatment. Smoke-stimulated species differed substantially in the duration of smoke exposure required to induce germination, and this was inversely correlated with tolerance to smoke exposure. We suggest that such differences in response may affect postfire community structure.

In clear water, UV-B may penetrate to significant depths. The purpose of the current study was to compare the sensitivity of freshwater invertebrates to UV-B. We used a solar simulator, calibrated to match local ambient solar radiation, to expose five species of freshwater invertebrates to enhanced levels of UV-B radiation. UV-B measurements in a eutrophic pond revealed that 10% of the irradiance penetrated to 30-cm depth and 1% to 57-cm depth. The irradiance at the upper 5-20 cm was comparable to levels used in the simulator. Median lethal dose (LD sub(50)) values were determined for the cladocerans Ceriodaphnia reticulata, Scapholeberis kingii (two induced color morphs), and Daphnia magna; the ostracod Cyprinotus incongruens; and the amphipod Hyalella azteca. Among the species, 96-h LD sub(50) estimates were quite variable, ranging from 4.2 to 84.0 mu W cm super(-2). These estimates indicated S. kingii to be highly sensitive and H. azteca, C. reticulata, and D. magna to be moderately sensitive, whereas the ostracod C. incongruens was very tolerant to UV-B radiation. Overall, this study suggests that, in shallow ponds without physical refuges, UV-B radiation would have the strongest effects upon cladocerans and amphipods occurring in the water column, whereas ostracods would be better protected.

Owens Lake records of total organic carbon, magnetic susceptibility, and chemical composition of the carbonate-free, clay-size fraction indicate that Tioga glaciation began similar to 24,500 and ended by similar to 13,600 super(14)C yr B.P.

Total organic carbon and SiO sub(2) (amorphous) concentrations reached minimum values during Tioga glaciation, resulting from decreases in productivity that accompanied the introduction of rock flour into the surface waters of Owens Lake. At least 20 stadial-interstadial oscillations occurred in the Sierra Nevada between 52,600 and 14,000 super(14)C yr B.P.

Shortly after the storm, we travelled some 400 km by river through the region and observed that scores of trees had been broken off or uprooted over an area estimated at greater than or equal to 5000 km super(2). That the damage was recent was confirmed by the presence of still-green leaves on the many damaged and fallen trees. To document the impact of the storm, we identified freshly-fallen trees to species, assuming that fallen trees with still-adherent leaves were killed by the storm. Because our intent was to examine the effects of high winds, we considered only those trees presumed to have been directly affected by the wind; trees knocked over by another tree (lying beneath the trunk or a large limb) were ignored. Consideration of such secondary damage would confuse the issue, particularly if trees affected directly were not themselves a random sample of those present in the forest.

Concentrations of dissolved (<0.45 mu m) uranium (U) were measured in surface waters of the Amazon shelf during rising (March 1990), flood (June 1990) and low (November 1991) discharge regimes. The dissolved U content was also examined in surface waters collected across estuarine gradients of the Mississippi outflow region during April 1992, August 1993, and November (1993). All water samples were analyzed for U by isotope dilution inductively coupled plasma mass spectrometry (ICP-MS). In Amazon shelf surface waters uranium increased nonconservatively from about 0.01 mu g l super(-1) at the river's mouth to over 3 mu g l super(-1) at the distal site, irrespective of river discharge stage. Observed large-scale U removal at salinities generally less than 15 implies a) that riverine dissolved U was extensively adsorbed by freshly-precipitated hydrous metal oxides (e.g., FeOOH, MnO sub(2)) as a result of flocculation and aggregation, and b) that energetic resuspension and reworking of shelf sediments and fluid muds on the Amazon shelf released a chemically reactive particle/colloid to the water column which can further scavenge dissolved U across much of the estuarine gradient. In contrast, the estuarine chemistry of U is inconclusive within surface waters of the Mississippi shelf-break region. U behavior is most likely controlled less by traditional sorption and/or desorption reactions involving metal oxides or colloids than by the river's variable discharge regime (e.g., water parcel residence time during estuarine mixing, nature of particulates, sediment storage and resuspension in the confined lower river), and plume dispersal. Mixing of the thin freshwater lens into ambient seawater is largely defined by wind-driven rather than physical processes. As a consequence, in the Mississippi outflow region uranium predominantly displays conservative behavior; removal is evident only during anomalous river discharge regimes. 'Products-approach' mixing experiments conducted during the Flood of 1993 suggest the importance of small particles and/or colloids in defining a depleted U versus salinity distribution.

Fuel biomass, fuel properties, fire behavior, biomass consumption, and changes in woody species density and height were documented before and after the burns. Before burning, Rosa nutkana (Nootka rose) was the most abundant woody species at both sites. In 1988, burns were significantly more intense, produced more heat per unit area at Fisher Butte than at Rose Prairie, and were fairly complete, with 37% and 35% woody biomass consumption, respectively. In 1989, burns were spotty; only 11% of woody biomass was consumed at Fisher Butte. The one-burn treatment did not affect R. nutkana density in 1 X 15 m transects at either site; the two-burn treatment significantly increased its density in three of the five communities sampled. Burning significantly reduced height growth by eliminating taller individuals while stimulating sprouts from belowground tissues. Redistribution of R. nutkana and trees into shorter height classes indicates the possibility of reducing the visual dominance of woody species if periodic burns were conducted in native Willamette Valley prairie. The low-intensity burns in this study were sufficient to remove the woody shoots under 3 m tall but did not reduce their capacity to regenerate and did not reduce the density of woody species. After decades of fire suppression, two burns were not sufficient to reestablish the desired balance between native herbaceous and woody species or to reduce the presence of introduced woody species. A long-term commitment to the reintroduction of fire as a management tool will be required to maintain native wetland prairies in the Willamette Valley.

Recently, concern has been expressed over a perceived increase in the beaver population and the impact of beaver on the long-term sustainability of the baldcypress ecosystem. We used intensive beaver lodge surveys to determine the distribution and relative abundance of beaver and the amount, type, and distribution of beaver damage to mature trees and seedlings at Caddo Lake. A total of 229 lodges were located with a combination of aerial and boat/ground surveys. Most lodges were located in open water and edge habitats. About 95% of the lodges were occupied by beaver or nutria. Some form of damage was exhibited by one or more trees near 85% of the lodges. Intensive damage assessments around 35 lodges indicated that most damage to trees, baldcypress in particular, was restricted to peeling or stripping of bark which is believed to have minimal effect on tree survival. Surveys of regeneration indicated that baldcypress seedlings were very abundant; however, over 99.9% were less than 30 cm tall. The lack of recruitment into the larger size classes appears to be a result of high stand densities and water management practices. At this time, the young age and density of the baldcypress forests suggest that recruitment is not a major concern and herbivore damage appears to be having a minimal effect on the forest.

The weathered volcanic rocks and sediments are collectively known as caprock, because they impede the free discharge of groundwater from the underlying volcanic aquifers. A cross-sectional groundwater flow and transport model was used to evaluate the hydrogeologic controls on the regional flow system in southwestern Oahu. Controls considered were: (a) overall caprock hydraulic conductivity; and (b) stratigraphic variations of hydraulic conductivity in the caprock. Within the caprock, variations in hydraulic conductivity, caused by stratigraphy or discontinuities of the stratigraphic units, are a major control on the direction of groundwater flow and the distribution of water levels and salinity. Results of cross-sectional modeling confirm the general groundwater flow pattern that would be expected in a layered coastal system. Groundwater flow is: (a) predominantly upward in the low-permeability sedimentary units; and (b) predominantly horizontal in the high-permeability sedimentary units.Original Abstract: Le systeme aquifere littoral du sud d'Oahu (Hawaii, Etats-Unis) est constitue par des aquiferes de terrains volcaniques tres permeables, recouverts par des roches volcaniques alterees, et interstratifies avec des sediments marins et continentaux de permeabilite aussi bien forte que faible. Les roches volcaniques alterees et les sediments sont globalement consideres comme une couverture, parce qu'ils s'opposent a l'ecoulement de l'eau souterraine provenant des aquiferes volcaniques sous-jacents. Les controles hydrogeologiques sur le systeme aquifere regional du sud-ouest d'Oahu ont eteevaluees au moyen d'un modele d'ecoulement et de transport sur une section transversale. Ces controles prennent en compte la conductivite hydraulique de la couverture dans son ensemble et les variations de la conductivite hydraulique liees a la stratigraphie de la couverture. A l'interieur de la couverture, les variations de la conductivite hydraulique, dues a la stratigraphie ou a des discontinuites entre les unites stratigraphiques, sont le controle principal de la direction d'ecoulement et de la repartition des niveaux et de la salinite de l'eau. La modelisation sur une section transversale a donne des resultats qui confirment l'organisation generale des directions d'ecoulement, telle qu'elle pouvait etre envisagee dans un aquifere littoral multicouche. L'ecoulement souterrain est essentiellement vertical vers le haut dans les unites sedimentaires a faible permeabilite, et essentiellement horizontal dans les unites sedimentaires a forte permeabilite.

The postulated maximum credible earthquake (MCE) for Hoover Dam is a magnitude Ms 6.75 on the Mead Slope Fault. Initial structural finite element analysis calculated stresses larger than the tensile strength on the upper portions of the dam. More sophisticated analysis followed when additional data was obtained for material properties and seismic loading. The first approach was a linear-elastic analysis incorporating foundation-structure interaction with mass in the foundation. The second approach was a non-linear analysis incorporating concrete cracking and contraction joint interaction using smeared crack techniques and kinematic stability analysis of the top of the dam.

The study area includes several known areas of mineralization including the Cornwallis Peninsula, Duncan Canal, Woewodski Island, Zarembo Island, and Groundhog Basin. Duncan Canal, Woewodski Island, and Groundhog Basin were the focus of the 1997 field effort. Bureau geologists and engineers visited a total of 48 mines and prospects and took 311 rock chip and stream sediment samples. This report provides results from samples taken in the 1996-97 field seasons. The Duncan Canal area, Woewodski Island, and Zarembo Island contain several occurrences of volcanogenic massive sulfide (VMS) mineralization hosted in Triassic rocks of the Alexander Terrane. The Alexander Terrane extends along the length of Southeast Alaska, and includes the Triassic age high-grade Greens Creek silver-lead-zinc-gold VMS deposit on northern Admiralty Island. Site specific examinations during this study coupled with newly created geophysical data and 1:63,360 scale geologic maps will help to more completely describe this VMS-style mineralization. The Groundhog Basin area contains a variety of deposit types, most importantly replacement-style mineralization and polymetallic veins. Several known occurrences were visited that had previously not been reported. Samples taken in 1997 indicate sufficient silver, lead and zinc mineralization to conduct further work in this area.

This project is designed to evaluate the status of sediments in the UMR and is one article in a series designed to assess the extent of sediment contamination in navigational pools of the river. Companion articles evaluate sediment toxicity and benthic community composition in navigation pools of the river. The objectives of the present study were to: (1) to assess the bioaccumulation of sediment-associated contaminants in the UMR using laboratory exposures with the oligochaete Lumbriculus variegatus, and (2) to compare bioaccumulation in laboratory-exposed oligochaetes to field-collected oligochaetes. Sediment samples and native oligochaetes were collected from 23 navigational pools on the Upper Mississippi River and the Saint Croix River. Contaminant concentrations measured in the L. variegatus after 28-day exposures to sediment in the laboratory were compared to contaminant concentrations in field-collected oligochaetes from the 13 pools where these sediments were collected. Contaminant concentrations were relatively low in sediments and tissues from the pools evaluated. Only polycyclic aromatic hydrocarbons (PAHs) and total polychlorinated biphenyls (PCBs) were frequently measured above detection limits. The majority of the biota-sediment-accumulation factors (BSAFs) for PAHs were within a range of about 1.0 to 2.6, suggesting that the theoretical BSAF value of 1.7 could be used to predict these mean BSAFs with a reasonable degree of certainty. A positive correlation was observed between lipid-normalized concentrations of PAHs detected in laboratory-exposed and field-collected oligochaetes across all sampling locations. Rank correlations for concentrations of individual compounds between laboratory-exposed and field-collected oligochaetes were strongest for benzo(e)pyrene, perylene, benzo(b,k)fluoranthene, and pyrene. About 90% of the paired PAH concentrations in laboratory-exposed and field-collected oligochaetes were within a factor of three of one another indicating laboratory results could be extrapolated to the field with a reasonable degree of certainty.

Whole-sediment tests were conducted with the amphipod Hyalella azteca for 28 days measuring the effects on survival, growth, and sexual maturation. Amphipod survival was significantly reduced in only one sediment (13B) relative to the control and reference sediments. Body length of amphipods was significantly reduced relative to the control and reference sediments in only one sample (26C). Sexual maturation was not significantly reduced in any treatment when compared to the control and reference sediments. No significant correlations were observed between survival, growth, and maturation to either the physical or chemical characteristics of the sediment samples from the river. When highly reliable effect range medians (ERMs) were used to evaluate sediment chemistry, 47 of 49 (96%) of the samples were correctly classified as nontoxic. These results indicate that sediment samples from the Upper Mississippi River are relatively uncontaminated compared to other areas of known contamination in the United States.

Water samples from Sugar Creek, two tile drains, and 11 wells along a groundwater flowpath to Sugar Creek were collected between May 1992 and August 1996 and analyzed for N and pesticide compounds. Nitrate was the principal N species and pesticides were common in alluvial water-bearing units in the Sugar Creek floodplain. In the confined stratified drift aquifers, ammonia was the principal N species and pesticides were rare. Tile drains directly affected the water quality in Sugar Creek by transporting soil pore water and shallow groundwater containing high concentrations of nitrate (NO sub(3)) and pesticides to the creek. When tile drains were flowing (typically December through July), elevated NO sub(3) concentrations (2-10 mg/L NO sub(3)N) in the creek correlated with high NO sub(3) concentrations (2-23 mg/L NO sub(3)N) in tile drains discharging to the creek. Likewise, with concentrations of atrazine and atrazine metabolites, seasonal trends in the tile-drain effluent were similar to seasonal trends in Sugar Creek. When tile drains went dry, NO sub(3) concentrations in the creek were low, indicating most groundwater discharge to the creek consisted of old or denitrified water. Trace levels of pesticides in the creek at low flow probably were the result of seepage from alluvial water-bearing units.

Fire suppression and fuelwood harvest likely have reduced oak abundance within the pine-oak type. Gambel oak occurs in multiple age-related growth forms, from small shrubs to large, old trees, and may provide important foraging and nesting habitat for breeding birds. I compared attributes of breeding bird communities in 16 northern Arizona ponderosa pine stands from 1993-1995, that were structurally similar except for the presence or absence of Gambel oak. Overlap in bird species composition was high; pine and pine-oak stands had a mean Jaccard similarity value of 0.67. Five species were unique to pine stands, whereas 10 species were largely restricted to or only found in pine-oak stands. Overall bird diversity was significantly higher in pine-oak stands, which also had more species of Neotropical migrants, ground nesters, primary cavity excavators, and secondary cavity users than did pine stands. Pine and pine-oak stands had similar species evenness and similar rates of annual species turnover. Total bird abundance did not differ between cover types; however, primary cavity excavators were more abundant in pine-oak stands. Because of the apparent positive influence of oak on breeding birds, forest managers are encouraged to use treatments that retain and enhance the various growth forms of Gambel oak found in pine-oak stands.

Numbers of leiothrix on our study areas showed a regular cyclical pattern, with highest numbers during the breeding season. Peak breeding occurred May-August, followed by peak molting of flight and body feathers in August-October. Flocking behavior increased post-breeding, and many leiothrix left the study areas during the fall and winter months. Populations on two intensive study areas were stable, with high annual survival (x plus or minus SE = 0.581 plus or minus 0.115 for hatching-year birds and 0.786 plus or minus 0.047 for adults). Leiothrix seem to be relatively unaffected by avian diseases that have decimated some Hawaiian bird populations, and yet reasons for their large historical population fluctuations remain unexplained.

We found that differences in body size, body condition, fluctuating asymmetry scores, wing coloration, territory location and behaviour (attraction, solicitation and agonistic) did not explain the observed variation in mating tactics used by males. Which males abandoned versus returned to leks was also not related to morphology or behaviour, and there was no tendency for males to join leks that were larger or smaller than the lek they abandoned. These results suggest that male desertion of leks was not dependent on a male's characteristics nor on the size of the lek he was presently attending. Males did join leks with larger males than their previous lek, perhaps to mate with females attracted to these larger 'hotshot' males. Males at both leks and solitary sites successfully mated. Lek tenure did not affect mating success, although lekking males appeared to mate more frequently than solitary males. Courtship disruption and to a lesser extent, female mimicry, were effective at preventing females from mating at leks, and may offer a partial explanation for female mating off leks. Our analysis that combined all males together within a year (regardless of mating tactic) indicated that males that attended leks for longer periods of time and that had fewer wing spots were significantly more likely to mate. Given some evidence that wing spotting declines with age, and that females inspect male underwings during courtship, the latter result suggests that female choice may play some role in determining male success. We suggest that male buff-breasted sandpipers may use alternative mating tactics more readily than males in other 'classic' lek-breeding species because: (1) unpredictable breeding conditions in this species' high arctic breeding range leads to low lek stability, which in turn hinders mate selection mechanisms mediated by male dominance and female choice; and (2) males are not constrained by morphological markings that indicate status or sex. Both characteristics may reduce the reproductive benefits associated with males adopting one mating tactic and result in a sort of scramble competition in which males switch between tactics as local conditions change.

Toxicity of sediment and sediment pore water was used to assess the current effects of major cities on sediment quality along the Lower Mississippi River. Composite sediment samples were collected from four sites upriver and four sites downriver of five major cities: Cairo, IL; Memphis, TN; Vicksburg, MS; Baton Rouge, LA; and New Orleans, LA. Acute toxicity was determined by exposing Hyalella azteca to solid-phase sediment for 10 days with two water renewals per day and to sediment pore water under static conditions for 96 h. After the initial tests, animals were exposed to ultraviolet light for 16 h. Sediments were analyzed for organics (organochlorine pesticides, PCBs, organophosphate insecticides, and PAHs) and metals (Cr, Cu, Pb, Mn, Ni, Zn). With the exception of upriver from Memphis, solid-phase sediments were not toxic to H. azteca. Pore water from sediments collected upriver of Memphis also showed slight toxicity. Exposure of H. azteca to ultraviolet light did not increase the toxicity of the sediment or pore-water samples, indicating a lack of toxicity from PAHs that are photoactivated by ultraviolet light. Chemical analyses did not reveal any contaminant levels of concern in the sediments. Based on toxicity testing and chemical analyses, quality of sediments collected from the Lower Mississippi was good, with the exception of sites sampled upriver of Memphis.

ER - TY - JOUR T1 - A comparison of small-mammal communities in a desert riparian floodplain AN - 17103206; 4411787 AB - We compared small-mammal communities between inactive floodplain and actively flooded terraces of riparian habitat in the Verde Valley of central Arizona. We used species diversity, abundance, weight of adult males, number of juveniles, number of reproductively active individuals, longevity, residency status, and patterns of microhabitat use to compare the two communities. Although abundances of small mammals tended to be higher in the active floodplain, species diversity was greater in the inactive floodplain. Results were inconsistent with our initial prediction that actively flooded riparian habitat acts as a species source, whereas inactive floodplain acts as a sink or dispersal site for small mammals. Within each habitat type, we found evidence of significant microhabitat separation among the three most abundant small-mammal species (Peromyscus boylii, P. eremicus, and Neotoma albigula). Percent cover by annual and perennial grasses and shrubs, substrate, and frequency of shrubs, trees, and debris were significant determinants of small-mammal distribution within a habitat type. We found that the three most abundant species selected a nonrandom subset of available habitat. Nonrandom use of habitat and microhabitat separation were the two most important mechanisms structuring small-mammal communities in riparian habitat of central Arizona.

Phylogenetic analysis of its 16S rRNA gene sequence indicates that strain IMB-1 classes in the alpha subgroup of the class Proteobacteria and is closely related to members of the genus Rhizobium. The ability of strain IMB-1 to oxidize MeBr to CO sub(2) is constitutive in cells regardless of the growth substrate. Addition of cell suspensions of strain IMB-1 to soils greatly accelerates the oxidation of MeBr, as does pretreatment of soils with low concentrations of methyl iodide. These results suggest that soil treatment strategies can be devised whereby bacteria can effectively consume MeBr during field fumigations, which would diminish or eliminate the outward flux of MeBr to the atmosphere.

Unfortunately, scientists, managers, and agencies often are stymied in their effort to conduct these large-scale studies because of a lack of appropriate technology, methodology, and funding. This issue is of particular concern in wetland conservation, for which the standard landscape approach may include consideration of a large tract of land but fail to incorporate the suite of wetland sites frequently used by highly mobile organisms such as waterbirds (e.g., shorebirds, wading birds, waterfowl). Typically, these species have population dynamics that require use of multiple wetlands, but this aspect of their life history has often been ignored in planning for their conservation. We outline theoretical, empirical, modeling, and planning problems associated with this issue and suggest solutions to some current obstacles. These solutions represent a tradeoff between typical in-depth single-species and more generic multi-species studies. They include studying within- and among-season movements of waterbirds on a spatial scale appropriate to both widely dispersing and more stationary species; multi-species censuses at multiple sites; further development and use of technology such as satellite transmitters and population-specific molecular markers; development of spatially explicit population models that consider within-season movements of waterbirds; and recognition from funding agencies that landscape-level issues cannot adequately be addressed without support for these types of studies.

We surveyed birds in 13 study sites ranging in size and connectivity from small isolated patches to extensive riparian forest, sampled vegetation and insects, and captured birds in mistnets. The continuous band of riparian vegetation along the San Pedro River does not appear to be functioning as a corridor for many migrating species, although it may for a few, namely Yellow-breasted Chats (Icteria virens), Summer Tanagers (Piranga rubra), and Northern Rough-winged Swallows (Steldigopteryx serripennis), which account for fewer than 10% of the individuals migrating through the area. Small, isolated oases hosted more avian species than the corridor sites, and the relative abundances of most migrating birds did not differ between sites relative to size-connectivity. There were few differences in between-year variability in the relative abundances of migrating birds between corridor and oasis sites. Between-year variability decreased with overall abundance of species and was greater for species with breeding ranges that centered north of 50 degree N latitude. Body condition of birds did not differ relative to the size-connectivity of the capture site, but individuals of species with more northerly breeding ranges had more body fat than species that breed nearby. Peak migration densities of several bird species far exceeded breeding densities reported for the San Pedro River, suggesting that large components of these species were en route migrants. Peak densities of Yellow Warblers (Dendroica petechia) reached 48.0 birds/ha, of Wilson's Warblers (Wilsonia pusilla) 33.7 birds/ha, and of Yellow-rumped Warblers (D. coronata) 30.1 birds/ha. Riparian vegetation is limited in extent in the vicinity of our study sites, covering less than 1% of the landscape. We conclude that all riparian patches in southeastern Arizona are important as stopover sites to en route migrants regardless of their size and degree of isolation or connectivity. In light of potential habitat limitation, the protection of both small, disjunct riparian patches and extensive riverine tracts in western landscapes is imperative.

Increased canopy cover is a major factor implicated in the decline of the Karner blue at many locales. Therefore, we examined how the butterfly's behavior varied with canopy cover. Adult males at Indiana Dunes National Lakeshore used habitat under canopy openings for nearly 90% of their activities; females used openings and shaded areas more equally. The frequency of oviposition on the sole host plant, wild lupine Lupinus perennis, was highest under 30-60% canopy cover even though lupine was more abundant in more open areas. Larvae fed preferentially on larger lupine plants and on lupines in denser patches. However, lupines were generally larger in the shade. Therefore, shade-related trade-offs existed between lupine abundance and distribution of larval feeding and oviposition. Also, heterogeneity of shading by sub-canopy woody vegetation was greater at oviposition sites than at sites where lupine did not grow. Given the importance of shade heterogeneity a mixture of canopy openings and shade, on a scale similar to daily adult movement range, should be beneficial for this butterfly.

The plan is unique because it includes a wetland component, recognizing the potential benefits to society from preserving wetland acreage. The contingent valuation method is used to estimate wetland benefits from the plan. The wetland benefits from the proposed plan are estimated to range from $832,000 to $2,100,000 annually. Agricultural benefits from the plan are estimated to be about $1,570,000 annually. The response rate to the mail survey used for this analysis was low. Therefore, survey techniques that increase response rates, such as in-person or telephone surveys, are recommended for future wetland valuation studies. Including a wetland component in the Turtle Lake plan substantially increases benefits while adding a relatively small amount to project costs.

Based on the load of reduced chemical species discharged to shallow ground water and the amounts of reactants in the aquifer matrix, it should be possible to determine chemical processes in the aquifer and compare observed results to predicted ones. At the Otis Air Base research site (Cape Cod, Massachusetts) where sewage effluent has infiltrated the shallow aquifer since 1936, bacterially mediated processes such as nitrification, denitrification, manganese reduction, and iron reduction have been observed in the contaminant plume. In specific areas of the plume, dissolved manganese and iron have increased significantly where local geochemical conditions are favorable for reduction and transport of these constituents from the aquifer matrix. Dissolved manganese and iron concentrations ranged from 0.02 to 7.3 mg/L, and 0.001 to 13.0 mg/L, respectively, for 21 samples collected from 1988 to 1989. Reduction of manganese and iron is linked to microbial oxidation of sewage carbon, producing bicarbonate and the dissolved metal ions as by-products. Calculated production and flux of CO sub(2) through the unsaturated zone from manganese reduction in the aquifer was 0.035 g/m super(2)/d (12% of measured CO sub(2) flux during winter). Manganese is limited in the aquifer, however. A one-dimensional, reaction-coupled transport model developed for the mildly reducing conditions in the sewage plume nearest the source beds showed that reduction, transport, and removal of manganese from the aquifer sediments should result in iron reduction where manganese has been depleted.

Delineating the topographically defined surface water basin and extending it vertically downward does not always define the ground water basin. Instead, a ground water basin is more appropriately delineated by tracking ground water flowpaths with a calibrated, three-dimensional ground water flow model. To determine hydrologic and chemical budgets of the basin, it is also necessary to quantify flow through each hydrogeologic unit in the basin. In particular, partitioning ground water flow through unconsolidated deposits versus bedrock is of significant interest to hillslope hydrologic studies. To address these issues, a model is developed and calibrated to simulate ground water flow through glacial deposits and fractured crystalline bedrock in the vicinity of Mirror Lake, New Hampshire. Tracking of ground water flowpaths suggests that Mirror Lake and its inlet streams drain a ground water recharge area that is about 1.5 times the area of the surface water basin. Calculation of the ground water budget suggests that, of the recharge that enters the Mirror Lake ground water basin, about 40% travels through the basin along flowpaths that stay exclusively in the glacial deposits, and about 60% travels along flowpaths that involve movement in bedrock.

A series of experiments conducted at a research site on Cape Cod, Massachusetts, examined the effects of transport on the chemistry of water samples obtained from a long-screened well. Analyses of time series of constituent concentrations in water pumped from the long-screened well showed persistent temporal trends during the first experiment. Iron concentrations decreased over a five-hour test (15 casing volumes), whereas the calcium and magnesium concentrations increased. In contrast, the time series of constituent concentrations of water discharging from the same well showed less change with time during a later experiment. Numerical simulations were undertaken to test the relative importance of several possible factors affecting the temporal variations of these constituents. During the process of quantitatively explaining the changes in concentrations over time observed in the two experiments, different system conceptualizations were used, including (1) flow and transport in the aquifer without wellbore transport, (2) flow and transport in the aquifer with advective flow and transport in the wellbore, and (3) flow and transport in the aquifer with advective flow and transport in the wellbore and a thin layer (skin) of water surrounding the well with constituent concentrations that had been altered by the presence of the well. The conjectured skin of wellbore water, which could have invaded the aquifer because of nearby sampling or dispersion and diffusion near the wellbore, in conjunction with flow and transport in the aquifer and advective transport within the wellbore, produced a reasonable match between the simulated and observed concentrations. The data analysis confirms the known fact that long-screened wells provide mechanisms for the redistribution of chemical constituents in the aquifer. The analysis provides new insight into the mechanisms responsible for the observed changes in concentrations during the sampling of long-screened wells. The analysis quantifies the effects of the various conceptual models of flow and transport in and around wells on the interpretation and meaning of chemical analyses of water withdrawn from long-screened wells.

The model assumes that turbulent head losses dissipate immediately when pumping ends. In wells subject to both borehole storage and turbulent head losses, the early-time recovery exhibits a slope equal to 1/2 on log-log plots of the recovery versus time. This half-slope response should not be confused with the half-slope response associated with a linear flow regime during aquifer tests. The presence of a borehole skin due to formation damage or stimulation around the pumped well alters the early-time recovery in wells subject to turbulent head losses and gives the appearance of borehole storage, where the recovery exhibits a unit slope on log-log plots of recovery versus time. Type curves can be used to estimate the formation storativity from the early-time recovery data. In wells that are suspected of having formation damage or stimulation, the type curves can be used to estimate the 'effective' radius of the pumped well, if an estimate of the formation storativity is available from observation wells or other information. Type curves for a homogeneous and isotropic dual-porosity aquifer are developed and applied to estimate formation properties and the effect of formation stimulation from a single-well test conducted in the Madison limestone near Rapid City, South Dakota.

AN - 70058553; 9827028 AB - Effects of a single dietary exposure to fenthion and carbofuran on the survival, feeding behavior and brain ChE activity of eastern screech-owls, Otus asio and American kestrels, Falco sparverius, were evaluated. Birds were exposed to fenthion (23.6-189.0 ppm) or carbofuran (31.7-253.6 ppm) via meatballs. Carbofuran-exposed owls ate either or = 80% of the meatball whereas all kestrels ate < or = 10% of the meatball before exhibiting acute signs of toxicity. Fenthion-exposed owls and kestrels displayed a wide spectrum of meatball consumption (< 10-100%). Significant brain ChE inhibition was observed in dead and surviving kestrels exposed to fenthion and carbofuran and dead owls exposed to fenthion (P < 0.0001). Brain ChE activity of owls exposed to carbofuran that survived was not different from that of controls (P = 0.25). Data suggest: (1) slow feeding on a carbamate-contaminated item may provide limited protection from the toxicity of the chemical at certain rates of exposure; (2) the degree of ChE inhibition at neuromuscular junctions may be critical in determining the sensitivity of a species to a carbamate insecticide; (3) sensitivity may be a function of the ChE affinity for the carbamate inhibitor; and (4) the importance of neuromuscular junction ChE depression in determining the sensitivity of an animal may be species-specific.

To provide additional insight into the influence of collection procedures on pore water chemistry, anion (filtered only) and cation concentrations were measured in filtered and unfiltered pore water isolated from four sediments using three different procedures: dialysis, centrifugation, and vacuum. Peepers were constructed using 24-cell culture plates and cellulose membranes and vacuum extractors consisted of fused-glass air stones attached with airline tubing to 60-cc syringes. Centrifugation was accomplished at two speeds (2,500 and 10,000 g) for 30 min in a refrigerated centrifuge maintained at 4 degreesC. Only minor differences in chemical characteristics and cation and anion concentrations were found among the different collecting methods with differences being sediment-specific. Filtering of the pore water did not appreciably reduce major cation concentrations, but trace metals (Cu and Pb) were markedly reduced. Although the extraction methods evaluated produced pore waters of similar chemistries, the vacuum extractor provided the following advantages over the other methods: ease of extraction, volumes of pore water isolated, minimal preparation time, and least time required for extraction of pore water from multiple samples at one time.

AN - 17132499; 4434748 AB - Vegetation and spring breeding bird populations associated with riparian forests on high and low order rivers of the Olympic peninsula, Washington (USA), were censussed in 1990 and 1991. The objectives were to (1) provide a baseline description of bird communities associated with unmanaged riparian forests, (2) determine whether there is a difference between bird communities along large and small rivers, and (3) identify what biophysical aspects of the fluvial corridor are most important in determining bird community structure. The approach was to link riparian bird community structure to river order and discuss relationships to vegetation, geomorphology and associated hydrologic disturbance regimes. Large rivers tended to have more deciduous vegetation than small rivers (P=0.07). Deciduous vegetation and patch types appeared to be linked to river size through stream valley shape and disturbance history. Bird species richness and abundance were significantly higher (P<0.05) on larger rivers (67-140 m width) than on small rivers (12-21 m width) and were positively correlated with the percentage of deciduous trees present at a site. The data suggest that migrant birds, such as the black-throated grey warbler (Dendroica nigrescens) and warbling vireo (Vireo gilvus), require large tracts of contiguous hardwoods for successful breeding. Additionally, birds such as the Hammond's flycatcher (Empidonax hammondii) and hairy woodpecker (Picoides villosus) appear to depend on the juxtaposition of hardwoods and conifers during the breeding season. We conclude that bird communities on large rivers differ from those on small rivers and that these differences occur predictably with stream order.

The mimetic seed hypothesis to explain this phenomenon proposes a parasitic relationship in which birds are deceived into dispersing seeds that resemble bird-dispersed fruits, without receiving a nutrient reward. The hard-seed for grit hypothesis proposes a mutualistic relationship in which large, terrestrial birds swallow the exceptionally hard mimetic seeds as grit for grinding the softer seeds on which they feed. They defecate, dispersing the seeds, and abrade the seed surface, enhancing germination. Any fruit mimicry is incidental. Fruiting trees of Ormosia spp. (Leguminosae: Papilionoideae) were observed to ascertain mechanisms of seed dispersal and the role of seemingly mimetic characteristics of the seeds in that dispersal. Seed predation and seed germination were also examined. Ormosia isthamensis and O. macrocalyx (but not O. bopiensis) deceived arboreally-foraging frugivorous birds into taking their mimetic seeds, although rates of seed dispersal were low. These results are consistent with the mimetic seed hypothesis. On the other hand, the rates of disappearance of seeds from the ground under the Ormosia trees, hardness of the seeds, and enhancement of germination with the abrasion of the seed coat are all consistent with the hard-seed for grit hypothesis.

(1997) recently drew attention to some pitfalls that can arise when trying to predict the responses of experimental manipulations from nonexperimental data using path analysis. Based on their analyses of experimental and nonexperimental data on rodent community interactions, they drew several conclusions: correlation coefficients and standardized path coefficients varied depending on the data set used, results based on nonexperimental data did not predict the effects of experimental treatments, results obtained from the long-term manipulation did not reveal certain known processes for one of the affected species, the pocket mouse, and they were unable to assess the overall fit of the path model to their data because the model was "just-identified" (i.e., they had an equal number of known and estimated parameters, which leaves no degrees of freedom for testing model fit). Based on these findings, the authors have pointed out potential limitations in the use of nonexperimental data as a means to analyze underlying mechanisms. In this note, we attempt to provide some additional insights into the issues raised by Smith et al. (1997). First, we discuss some difficulties with the interpretation of traditional path analysis results. Second, we reconstruct their covariance matrices and then use structural equation modeling (SEM) to perform a multigroup analysis and to make comparisons between predicted and observed mice densities. Third, we discuss the question of what we can reasonably expect from path modeling methods.

Neither flooding, drying, nor the presence or absence of surrounding vegetated wetlands had a great effect on chemical composition, which was very dilute and fluctuated somewhat in response to rain events. Neither flooding nor drying affected the composition of biological communities in the pools. Summer storms affected only a few drainages at a time, and only a few study pools of significant volume dried completely during the hot, dry summer. This suggests that only a portion of the Waterpocket Fold aquatic community is ever disturbed at a time, leaving undisturbed areas as a source of recovery. Pools bordered by vegetated wetlands always supported greater numbers of species throughout the year than those bordered only by bedrock, but the same taxa were found in both vegetated and bedrock pools. The rock pool fauna in Capitol Reef National Park appear to be resilient to climatic variability.

Park ER - TY - JOUR T1 - Change in emphasis for hydraulic research at Bureau of Reclamation AN - 16469962; 4393737 AB - Throughout its illustrious history, the Bureau of Reclamation has focused its efforts on creating a life-sustaining environment in the once-barren west. The Bureau has constructed over 220 dams since it was established in 1902. Its hydraulic research, which started in the early 1930s, played a key role in developing innovative designs and establishing standards for dams and many other hydraulic structures. At first the Bureau's hydraulic research dealt with dam structures such as spillways, outlet works, and their energy dissipators. Over time its research expanded to include hydraulic equipment and various conveyance systems for irrigation and municipal and industrial water supplies. This article describes the Bureau's current research emphasis, which aims at using hydraulic structures to manage water resources in an environmentally, economically, and structurally sound manner. The Bureau of Reclamation's hydraulic structures research in the period from 1930 through the 1970s resulted in world-class technological advancements in water-resource development, documented in publications such as Design of Small Dams (1960) and Engineering Monograph No. 25, "Hydraulic Design of Stilling Basins and Energy Dissipators" (1958). As public values have shifted from an emphasis on water resource development to management of western waters, the Bureau's contemporary hydraulic research program has also changed. This evolution from water development to water management has led to an emphasis on technology innovation for protecting the public and existing infrastructure, encouraging water conservation, and emphasizing environmental restoration on regulated river systems. Much of the technology innovation is being performed at the Bureau of Reclamation Water Resources Research Laboratory (WRRL).

Uptake rate constants for individual chemicals are needed to accurately relate the amounts of chemicals accumulated by the SPMD to dissolved water concentrations. Brown trout (Salmo trutta) and SPMDs were exposed to PCB-contaminated groundwater in a spring for 28 days to calculate and compare uptake rates of specific PCB congeners by the two matrixes. Total PCB congener concentrations in water samples from the spring were assessed and corrected for estimated total organic carbon (TOC) sorption to estimate total dissolved concentrations. Whole and dissolved concentrations averaged 4.9 and 3.7 mu g/L, respectively, during the exposure. Total concentrations of PCBs in fish rose from 0.06 to 118.3 mu g/g during the 28-day exposure, while concentrations in the SPMD rose from 0.03 to 203.4 mu g/g. Uptake rate constants (k sub(1)) estimated for SPMDs and brown trout were very similar, with k sub(1) values for SPMDs ranging from one to two times those of the fish. The pattern of congener uptake by the fish and SPMDs was also similar. The rates of uptake generally increased or decreased with increasing K sub(OW), depending on the assumption of presence or absence of TOC.

Late spring snowmelt is the principal means of recharging the fractured Paleozoic-age carbonate rocks comprising the central and highest portion of the Spring Mountains. Daily discharge measurements at Peak Spring Canyon Creek during the period 1978-94 show that snowpacks were greatly enhanced during El Nino events.Original Abstract: La comparaison des signatures isotopiques stables des eaux de sources, de neige, de fonte de neige, des pluies d'ete (juillet a septembre) et de saison froide (octobre a juin) montre que les precipitations convectives d'ete de forte intensite et de courte duree, apportant un tiers des precipitations annuelles recues par les Monts Spring, ne participent que pour une faible part (10%) a la recharge de cette importante zone d'altitude du sud du Nevada (Etats-Unis). La fonte tardive de la neige au printemps constitue l'essentiel de la recharge des roches carbonatees fracturees d'age paleozoieque formant la partie centrale et la plus haute des Monts Spring. Les donnees journalieres de debit sur la riviere du canyon de Peak Spring, entre 1978 et 1994, montrent que les hauteurs de neige ont ete plus elevees pendant les evenements El Nino.

This effort is being conducted on a region-by-region basis using U.S. Standard Federal Regions. To date, land cover data sets have been generated for Federal Regions 3 (Pennsylvania, West Virginia, Virginia, Maryland, and Delaware) and 2 (New York and New Jersey). Classification work is currently under way in Federal Region 4 (the southeastern United States), and land cover mapping activities have been started in Federal Regions 5 (the Great Lakes region) and 1 (New England). It is anticipated that a land cover data set for the conterminous United States will be completed by the end of 1999. A standard land cover classification legend is used, which is analogous to and compatible with other classification schemes. The primary MRLC regional classification scheme contains 23 land cover classes. The primary source of data for the project is the Landsat thematic mapper (TM) sensor. For each region, TM scenes representing both leaf-on and leaf-off conditions are acquired, preprocessed, and georeferenced to MRLC specifications. Mosaicked data are clustered using unsupervised classification, and individual clusters are labeled using aerial photographs. Individual clusters that represent more than one land cover unit are split using spatial modeling with multiple ancillary spatial data layers (most notably, digital elevation model, population, land use and land cover, and wetlands information). This approach yields regional land cover information suitable for a wide array of applications, including landscape metric analyses, land management, land cover change studies, and nutrient and pesticide runoff modeling.

The sulfonic and oxanilic metabolites were present in almost 75% of the groundwater samples and were generally present from 3 to 45 times more frequently than their parent compounds. In groundwater, the median value of the summed concentrations of acetochlor, alachlor, and metolachlor was less than 0.05 mu g/L, and the median value of the summed concentrations of the six metabolites was 1.2 mu g/L. All surface water samples contained at least one detectable metabolite compound. Individual metabolites were detected from 2 to over 100 times more frequently than the parent compounds. In surface water, the median value of the summed concentrations of the three parent compounds was 0.13 mu g/L, and the median value of the summed concentrations of the six metabolites was 6.4 mu g/L. These data demonstrate the importance of analyzing both parent compounds and metabolites to more fully understand the environmental fate and transport of herbicides in the hydrologic system.

We placed a major emphasis on a study site in central Eleuthera, with additional information from sites on Grand Turk, North Caicos, and Crooked Island. The warblers used upland habitats that have a low shrub/scrub component with a mosaic of small openings and openings within the vegetation at the ground level. Six broad habitats were used: natural shrub/scrub, secondary shrub/scrub, low coppice, pineland understory, saline/upland ecotone, and suburban; high coppice was not used. The structure and floristic composition of the habitats are described. Observations (n = 451) of a Kirtland's Warbler male (uniquely color banded) and female over three months indicated the birds generally stayed within 3 m of the ground (98% of observations), and used a territory of 8.3 ha. A crude estimate of potential winter habitat suggests that not only is there more than an adequate amount in the Bahama Archipelago for the current small population of warblers (733 singing males in 1997), but also enough for a considerably larger population. No serious future threat to the amount of that habitat is foreseen.

Annual reproductive success was significantly different among years; ranging from 10-25% (Mayfield estimate) over the three years of the study. There was no significant difference in nest success among study plots, with nesting success showing a trend of increasing late in the breeding season. Clutch size for nonparasitized nests averaged 2.9 plus or minus 0.02 (SE) eggs with a mode of 3. Rates of Brown-headed Cowbird (Molothrus ater) parasitism were low (21%), accounting for 7% of all nest failures. However, parasitism by cowbirds resulted in a reduction of clutch size for nests initiated early (i.e., first nests and replacements) in the breeding season. Predation was the leading cause of nest failures, accounting for 75% of all failures. Snakes and avian predators were thought to be the leading cause of nest failures. Although additional factors must be investigated, preliminary results indicate that nest predation is a major influence on this population, despite the size of the forest tract.

We used a 10-year data base on the aquatic biota of Shark Slough to classify vegetation and describe plant community change in intermediate- to long-hydroperiod Everglades marshes. Study area marsh vegetation was quantitatively grouped into associations dominated by 1) Cladium jamaicense, 2) a group of emergents including Eleocharis cellulosa, Sagittaria lancifolia, and Rhyncospora tracyi, 3) taxa associated with algal mats (Utricularia spp. and Bacopa caroliniana), and 4) the grasses Panicum hemitomon and Paspalidium geminatum. During the decade evaluated, the range of water depths that characterized our study sites approached both extremes depicted in the 40-year hydrologic record for the region. Water depths were near the long-term average during the mid-1980s, declined sharply during a late 1980s drought, and underwent a prolonged increase from 1991 through 1995. Overall macrophyte cover varied inversely with water depth, while the response of periphyton was more complex. An ordination analysis, based on plant species abundance, revealed that study area vegetation structure was associated with hydrologic patterns. Marsh plant community structure showed evidence of cyclic interannual variation corresponding to hydrologic change over the decade evaluated. Lower water depths, the occurrence of marl substrates, and high periphyton cover were correlated. These factors contributed to reduced macrophyte cover in portions of the study area from which water had been diverted.

Fish were sampled from single-species and mixed assemblages in 2-m super(3) cages for 8 weeks during April and May. Both species initially ate mostly cyclopoid copepodites and small cladocerans (Bosmina spp.). Schoener's index of diet overlap showed considerable overlap (70-90%). Lake whitefish ate Daphnia spp. and adult copepods about 2 weeks earlier than did lake herring, perhaps related to their larger mean mouth gape. Lake whitefish were consistently larger than lake herring until the eighth week, especially in the sympatric treatments. Lake whitefish appeared to have a negative effect on the growth of lake herring, as lake herring in mixed-species treatments were smaller and weighed less than lake herring reared in single-species treatments. The diet similarities of lake whitefish and lake herring larvae could make them competitors for food in the Great Lakes. The greater initial size of lake whitefish could allow them to eat larger prey earlier and thereby limit availability of these prey to lake herring at a crucial period of development.

Stomach contents of the 39 birds included 2,092 different food items representing 13 orders and at least 16 families of invertebrates. Diets at each of the three locales differed greatly, with coleopterans and hymenopterans dominating the Carrizo samples, lepidopterans the Pixley samples, and coleopterans and orthopterans the Salton Sea samples. Diets of males and females were similar. These findings counter the current perception that Mountain Plover diets are specialized on coleopterans and orthopterans, and bring the species more in line as a dietary generalist/opportunist as reported for most shorebirds.

In this study, a combination of field geochemical analyses and laboratory radiotracer ([1,2- super(14)C] vinyl chloride) experiments was utilized to assess the potential for intrinsic biodegradation of vinyl chloride contamination in an Fe(III)-reducing, anaerobic aquifer. Microcosm experiments conducted under Fe(III)-reducing conditions with material from the Fe(III)-reducing, chlorinated-ethene contaminated aquifer demonstrated significant oxidation of [1,2- super(14)C] vinyl chloride to super(14)CO sub(2) with no detectable production of ethene or other reductive dehalogenation products. Rates of degradation derived from the microcosm experiments (0.9-1.3% d super(-1)) were consistent with field-estimated rates (0.03-0.2% d super(-1)) of apparent vinyl chloride degradation. Field estimates of apparent vinyl chloride biodegradation were calculated using two distinct approaches; 1) a solute dispersion model and 2) a mass balance assessment. These findings demonstrate that degradation under Fe(III) reducing conditions can be an environmentally significant mechanism for intrinsic bioremediation of vinyl chloride in anaerobic ground-water systems.

Concentrations of 19 inorganic analytes were determined in the livers. Differences between sexes in diet or abilities to retain some analytes are indicated because male willets tend to have greater levels of Cd than females and male plovers tend to have greater levels of Fe, Hg, and Mn than females. Concentrations of Hg and Mg in willets decreased from January to November. If this decrease is a part of an annual cycle, then the birds may be acquiring those elements while at NASNI. The differences between sites shows higher levels of As and Se but lower levels of Mn in willets at NASNI while plovers have lower levels of Cu, Mg and Zn at NASNI. There were no correlations between Hg and Se concentrations in the livers of any sample group of birds.

ER - TY - JOUR T1 - Toward a national program for monitoring environmental resources AN - 16412553; 4325944 AB - A conceptual framework is presented for integrating the nation's environmental research and monitoring networks, which will enable comprehensive and integrated assessments of natural resources. This framework can link inventories and remote sensing, national and regional resources surveys, and intensive monitoring and research sites with research and modeling to produce an integrated national environmental monitoring program. This integration of the nation's major environmental monitoring and research networks can allow understanding, assessment, evaluation, and forecasting of its renewable natural resources at national and regional scales. It can also enhance and support our understanding and ability to predict the causes and consequences of environmental change and ecosystem response, address multiple scales of ecosystem and resource interactions, and allow system-level syntheses and assessments of data and information. Network integration provides an "added value" that the current array of fragmented single-purpose networks cannot.

AN - 79972719; 9646439 AB - Renibacterium salmoninarum is a facultative intracellular pathogen often found in host phagocytes where it appears to successfully avoid the host fish's immunological defenses. The objective of this investigation was to determine if soluble extracellular protein (ECP) produced by R. salmoninarum may contribute to the immunomodulation in bacterial kidney disease (BKD) via inhibition of phagocyte respiratory burst and/or phagocytosis mechanisms. Splenic cells from adult brook trout (Salvelinus fontinalis) were incubated with two different concentrations of ECP (0.1 mg/ml and 1.0 mg/ml) and viable R. salmoninarum. Splenic cell cultures were evaluated for respiratory burst activity via flow cytometry with the dichlorofluorescin diacetate (DCF-DA) assay and for phagocytosis via light microscopic assessment of microsphere engulfment. Respiratory burst activity was significantly inhibited in all treatment groups as compared to untreated fish, while no differences were noted in phagocytic activity.

AN - 17482763; 4676528 AB - Topographic alteration may encourage invasion of the exotic species English ivy (Hedera helix L.) in floodplain forest. To test that hypothesis, I designated 16 sampling stations on the floodplain of Rock Creek Park in Washington, D.C. Eight of the stations were on the spoil ridge that resulted from construction of a sewer line in 1927 (median height = 22 cm). In 1983 the ground layer of half of each station on the spoil ridge and on the "flat" near the ridge were dominated by English ivy; other stations were ivy-flee. By 1989 English ivy had invaded four of the ivy-free stations. This increase in ivy abundance was not statistically significant on the "flat" but was significant ( chi super(2) sub(Y, 1df), p<0.1) on the ridge. There was no significant difference ( chi super(2) sub(Y, 1df), p<0.1) between ivy rooting depth on the sewer ridge and on the flat, indicating that good soil conditions were present in both places. Basal area of the trees dominating the sites differed: the "flat" had 69 m super(2) ha super(-1) while the spoil ridge had 59 m super(2) ha super(-1). The results support the hypothesis that a slight alteration of topography influences patterns of invasion by English ivy.

Estimates of cumulative losses of floodplain forest range from 57% to 95% at different locations within the continental United States. Floodplain forests of the Upper Mississippi River (UMR) have significantly declined in extent due to agriculture, lock and dam construction, and urban development since European settlement. We collected data on shrubs, herbs, and trees from 56 floodplain forest plots in 1992 and compared our results with a previous analysis of historical tree data from the same area recorded by the General Land Office Survey in the 1840s. Acer saccharinum strongly dominates among mature trees and its relative dominance has increased over time. Salix spp. and Betula nigra have declined in relative dominance. Tree sizes are similar to those of presettlement forests, but present forests have fewer trees. The lack of early successional tree species and a trend toward an increasing monoculture of A. saccharinum in the mature stages indicate problems with regeneration. Because floodplain forests represent a rare habitat type, losses and changes in habitat quality could pose serious problems for wildlife that depend upon these habitats, especially birds.

Previously available estimators are maximum likelihood under the general model, but they use only 1 type of data and require the assumption of a stable age structure and a known population growth rate. We used the general model to derive new survival rate estimators that use both types of data and require only the assumption of a stable age structure or a known population growth rate. Our likelihood-based approach allows use of standard model-selection procedures to test hypotheses about age-structure stability, population growth rates, and age-related patterns in survival. We used this approach to estimate survival rates for female sea otters (Enhydra lutris) in Prince William Sound, Alaska.

Collectively, 93 taxa were identified in 55 samples from 51 lakes. Based on cell densities, cyanobacteria had the highest relative abundance (36.7%), followed by chlorophytes (29.8%), and chrysophytes (19.6%). Aphanocapsa delicatissima had the highest proportional abundance (14.0%). Only 15.1% percent of the taxa occurred in more than 20 samples. Phytoplankton cell densities increased following a gradient of increasing lake-water temperature, alkalinity, and concentration of total Kjeldahl-N with decreasing lake elevation. Chrysophytes and cyanobacteria were quantitatively (relative abundance) the most important taxa in alpine and subalpine lakes, whereas cyanobacteria had the highest relative abundances in high-forest and low-forest lakes. Chlorophytes had their highest relative abundance in high-forest lakes. Although low in relative abundance, diatoms and dinoflagellates were most abundant in alpine lakes. An ordination by correspondence analysis indicated that most alpine, subalpine, and high-forest lakes had similar floras. Although a few subalpine lakes exhibited deviations from this pattern, the main differences in phytoplankton composition were found in a group of low-forest and high-forest lakes. Canonical correspondence analysis (CCA) provided evidence that the distribution of samples and taxa in ordination space was correlated with a gradient of decreasing lake elevation and increasing water temperature, alkalinity, and concentration of nitrogen. When CCA was used to examine relationships among phytoplankton taxa and vegetation zones, a continuous distribution of taxa was found from the low-forest zone to the subalpine zone, with a large number of taxa occurring primarily in the subalpine and high-forest zones. Three phytoplankton taxa occurred primarily in alpine lakes, whereas five taxa co-occurred in alpine, subalpine, and high forest zones. Collectively, lake elevation and associated changes in water quality and concentrations of nutrients, especially nitrogen, appeared to be the primary physical and chemical factors influencing the taxonomic structures of phytoplankton assemblages.

The index was composed of two subdivisions that described, at the county level, the quantity of wildlife habitat and a third subdivision that described farming disturbances that impacted the quality of the habitat. Data came from the US Census of Agriculture. The first subdivision that reflected quantity of habitat was called the wildlife habitat subdivision and was the sum of percentage woodland on farms, percentage farmland in nonrow crops, and percentage farmland in set-aside programs. The second subdivision that reflected the quantity of habitat was termed the soil-related features subdivision and was the sum of the percentage of farmland that was not highly erodible, the percentage of farmland in soil-protecting crops, and the percentage of farmland in conservation tillage. The third subdivision, reflecting the quality of the habitat, was the farming disturbance subdivision and was the sum of the percentage of grazing and the percentage of land on which fertilizers, pesticides, and herbicides were applied. Overall, major decreases occurred between 1920 and 1987 in the subdivisions reflecting the quantity of wildlife habitat and a major increase occurred in the subdivision associated with farming disturbance, reflecting the intensification of agriculture in the state. However, there was variability throughout the state, with some counties being more favorable to wildlife (as measured by the subdivisions) than others. Most of the changes within the state for the subdivisions reflecting quantity of upland wildlife habitat occurred during 1940 while changes in the farming disturbance subdivision (reflecting habitat quality) occurred in 1964. By 1987, the western and southern parts of Illinois were the most favorable for wildlife as reflected in all three subdivisions. Upland wildlife harvest indices were related to the subdivisions in 1964 and 1987, when harvest indices were available. Cottontail and northern bobwhite harvests were higher in counties with higher amounts of the wildlife habitat subdivision in both years. Cottontail harvest was also higher in counties with lower levels of the farming disturbance subdivision in 1964 and higher levels of soil-related features subdivision in 1987. Indices at the county level have the potential to be used in a multiscale analysis to investigate the impact of policy changes on large-scale areas of the Midwest and to develop regional perspectives of the impacts of agriculture on upland wildlife and their habitats.

We used canonical discriminant analysis and univariate tests to determine microhabitat variables that were important in segregating species. Darter species were segregated by depth, substrate size, and water velocity. In addition, Percina typically occurred in the water column, whereas species of Etheostoma were benthic and segregated by occurring under, between, and on top of rocks.

Juvenile M. robustum were tested for tolerances to temperature, salinity, pH, and hypoxia in order to evaluate basic early life-history requirements. Static (acute) tests resulted in estimates of mean lower temperature tolerances (5.3-19.4 degree C) that varied with prior thermal acclimation and indicated no apparent difference in tolerance among fish 30, 60, and 90 days old. Fish acclimated to 20 degree C and 30 degree C had significantly different mean critical thermal maxima (34.9 degree C and 37.2 degree C, respectively) and exhibited pronounced increased opercular ventilation rates with elevated temperatures. Fish exposed to acute and chronic increases in salinity showed unusual patterns of mortality above the isosmotic point (9 ppt) that reflected possible differences in body mass and prior acclimation conditions (i.e., water ionic composition); small fish and those held in soft water were the least tolerant of increased salinity. Abrupt exposure to extreme pH values resulted in greater than 50% mortality at pH values below 4.3 and above 9.5 within a 96-hour period. Fish exposed to progressive hypoxia utilized aquatic surface respiration at a mean oxygen concentration of 0.72-0.80 mg O sub(2) l super(-1) (20 degree C and 30 degree C acclimated fish, respectively), and lost equilibrium at 0.54-0.57 mg O sub(2) l super(-1). Juvenile M. robustum are moderately tolerant of a wide range of ambient physicochemical parameters, but further research is needed to determine how both abiotic and biotic factors have contributed to population decline and extirpation of this species.

Acute 48 h toxicity tests were conducted to determine the LC sub(50) values for each species. The initial uptake clearances of TFM were measured by exposing the mussels to [ super(14)C]-TFM and counting the radioactivity in four organ tissues (foot, gill, mantle and viscera) over 48 h. TFM was about 2-fold more toxic to O. reflexa (LC sub(50) 1.80 mg l super(-1)) than to F. flava (LC sub(50) 3.81 mg L super(-1)) and the difference was not explained by accumulation patterns. The initial uptake clearance rates (0-6 h) for the whole body were similar between the species (11.2 ml g super(-1) h super(-2) in O. reflexa and 9.5 ml g super(-1) h super(-1) in F. flava). The accumulation of TFM residues among the organ tissues was also similar between species. The uptake clearance rates (ml g super(-1) h super(-1)) of TFM equivalents were generally highest in the gill, but not significantly different than other organ tissues. The normalized concentration of TFM residues ( mu g per g whole body) was highest in the viscera. The toxicity data suggest that the mortality of both species would be minimal from sea lamprey control treatments with TFM. However, the behavioural effects and accumulation rates also indicate that mussels do not effectively avoid TFM exposure by valve closure.

These problems are typically not the result of an unexpected event, but are the result of growth trends or decreasing water quality experienced over several years. This analysis uses the contingent valuation and benefit transfer methods to evaluate the willingness to pay for a rural water system in northcentral Montana. Both of the procedures resulted in similar values, ranging from about $4.05 to $7.50 per household per month for urban residents and $5.40 to $11.50 per household per month for rural residents, which is equal to 11 percent to 23 percent of current average water costs. The willingness to pay estimates do not include non-household water users. This analysis shows that useful planning information can be obtained from relatively inexpensive contingent valuation mail survey data and the benefit transfer method as long as the limitations of the data are understood. The willingness to pay for ensuring good quality rural water supplies in the future is likely to be low compared to the costs of extensive diversion and treatment systems. Willingness to pay estimates provide decision makers with information that can be used to avoid building a large water supply system that water users do not want to connect to because of high costs.

To do this, we examined blood from a total of 26 green turtles from Puako on the island of Hawaii and Kaneohe Bay on the island of Oahu. Blood was examined using a combination of light and electron microscopy and cytochemical stains including benzi-dine peroxidase (PER), chloroacetate esterase (CAE), alpha naphthyl butyrate esterase (NBE), acid phosphatase (ACP), Sudan black B (SBB), periodic acid-Schiff (PAS), and tolui-dine blue (TB). We recognized 6 types of leukocytes including lymphocytes, monocytes, thrombocytes, heterophils, basophils, and small and large eosinophils. Cell morphology of mononuclears and most granulocytes were similar to that of other reptiles except that green turtles have both large and small eosinophils. Our classification of green turtle blood cells clarifies improper nomenclature reported previously and provides a standard base of reference for future hematologic studies in this species and allows for hematologic comparison of healthy and unhealthy aggregations.

In this study we investigate how this resistance influences Cd trophic transfer from this oligochaete to the grass shrimp Palaemonetes pugio. Cadmium-resistant worms collected from FC and nonresistant worms collected from an adjacent unpolluted site were investigated for differences in Cd tolerance, accumulation, subcellular distribution and bioavailability to shrimp. FC worms were more tolerant of Cd, surviving twice as long as worms from the unpolluted site during a toxicity bioassay. The 7 d concentration factor of Cd-resistant worms was 4 times greater than that of nonresistant worms (2020 vs 577). There were also differences between worm populations with respect to subcellular Cd distributions. Cd-resistant worms produced metallothionein-like proteins (MT) as well as metal-rich granules (MRG) for Cd storage and detoxification; nonresistant worms only produced MT. These differences in subcellular Cd distributions led to large differences in Cd bioavailability to shrimp; shrimp fed Cd-resistant worms absorbed 21% of the ingested Cd, while those fed nonresistant worms absorbed roughly 4 times that amount ( similar to 75%). These absorption efficiencies were in good agreement with the proportions of Cd bound to the worm's most biologically available subcellular fractions (i.e. the cytosol and organelles). Although Cd-resistant worms predominantly stored the toxic metal in biologically unavailable MRG, their increased accumulation of Cd would still result in substantial trophic transfer to shrimp because of the storage of Cd in the biologically available fractions. This work demonstrates that the evolution of Cd resistance can have profound implications for Cd bioavailability and cycling within aquatic ecosystems.

The primary objective was to document summer monthly and annual variability in Secchi disk readings, and variation caused by observers, disk size, and surface condition of the lake. An additional objective was to determine differences between descending and ascending disk readings (the averages of the two readings representing the disk readings) relative to the depth of the Secchi disk readings, lake surface conditions, and disk size. Secchi disk data were collected from June through September, 1978-1995. Secchi disk depths typically were in the high 20- to low 30-m range. Secchi disk readings were deepest in June and shallowest in August. Average monthly disk readings exhibited considerable variation among years (9.4 m in June, 13.4 m in July, 13.0 m in August, and 8.2 m in September). On average, variation in Secchi disk readings among observers was 1 m or less. When the lake surface was calm and skies were clear or had high haze, differences between descending and ascending observations decreased slightly with increased disk depth. Waves from tour boats, drips of water from the research vessel, and wind generated ripples and chop decreased disk readings as much as 5 m relative to readings recorded when the lake surface was calm. Clarity readings using a 100-cm disk were 7.0 m deeper than were 20-cm disk readings. Documentation of the extensive variation in Secchi disk clarity is needed to determine "normal" conditions and to judge the long-term status and trends of lake clarity. Furthermore, documenting the variation caused by slightly disturbed lake surface conditions relative to calm surface conditions and among trained observers ensures consistent interpretation of the long-term data base.

The pressure-normalized permeate flow (NPF) and salt rejection were evaluated before and after fouling with a vegetable protein broth. Surface changes were characterized using atomic force microscopy and electro-kinetic analysis. The transport results from both the swatch and element testing were used in a simple economic model to assess operating costs. Results indicate that cost savings are possible based on the changes in NPF and salt rejection.

DNA sequencing, MHC (major histocompatibility complex), minisatellite, microsatellite, and RAPD (random amplified polymorphic DNA) procedures allow for identification of parentage, more distant relatives, founders to new populations, unidentified individuals, population structure, effective population size, population-specific markers, etc. PCR (polymerase chain reaction) amplification of mitochondrial DNA, nuclear DNA, ribosomal DNA, chloroplast DNA, and other systems provide for more sophisticated analyses of metapopulation structure, hybridization events, and delineation of species, subspecies, and races, all of which aid in setting species recovery priorities. Each technique can be powerful in its own right but is most credible when used in conjunction with other molecular techniques and, most importantly, with ecological and demographic data collected from the field. Surprisingly few taxa of concern have been assayed with any molecular technique. Thus, rather than showcasing exhaustive details from a few well-known examples, this paper attempts to present a broad range of cases in which molecular techniques have been used to provide insight into conservation efforts.

We tested whether (1) species accumulation curves follow the form predicted by the model, (2) the model gives unbiased estimates (S and B, respectively) of S and of the sample size, B, needed to detect S/2 species, and (3) performance is robust to community structure. Performance varied with community structure. For model communities with species-abundance distributions based on MacArthur's broken-stick model with 100 or 1000 species, deviations from predicted accumulation curves were slight, and S and B were unbiased (P greater than or equal to 0.18). For broken-stick communities with 10 species, S and B overestimated S and B by an average of 17% and 63%, respectively (P < 0.001). For model communities with species-abundance distributions based on Tokeshi's (1990) random-fraction model with 10, 100, or 1000 species, deviations from predicted accumulation curves were large; on average, S underestimated S by 7-37% (P < 0.001), and (for S = 100 or 1000) B underestimated B by 67-80% (P < 0.001). Vascular plant inventories (S = 42 to 99 species) also showed large deviations from predicted curves; on average, S underestimated S by 35% (P < 0.001) and B underestimated B by 72% (P < 0.001). Because most natural communities are better described by the random-fraction than the broken-stick model, we suggest the Michaelis-Menten model will typically yield poor estimates of S. Moreover, we argue that accepted criteria for evaluating estimators of S are inadequate. JF - Oikos AU - Keating, KA AU - Quinn, J F AD - USGS Greater Yellowstone Res.

We examined 19 trace elements in the eggs and livers of geese from these two subpopulations to examine whether geese from the different wintering areas have similar trace element burdens. Eggs collected at the breeding colony from geese of the southern subpopulation had slightly higher levels of manganese, an element that can cause neurological damage and behavioral changes in chicks, than geese of the northern subpopulation. Livers from adult geese collected on the two wintering areas showed significant differences in trace elements including copper, iron, magnesium, molybdenum, and zinc. Copper concentrations in the livers of geese from the southern subpopulation were much higher than those from the northern subpopulation (x super(-) = 116 vs. 46 ppm; dry weight). Elevated levels of copper may induce anemia in birds. The differences in trace element concentrations of these two subpopulations may be related to farming practices in their wintering areas. Geese from the northern subpopulation feed in pastures and coastal marshes and migrate along the coast, but geese from the southern subpopulation feed predominantly in rice fields and migrate over farm land. Copper and manganese are major components of fertilizers and fungicides commonly applied during rice cultivation.

ER - TY - JOUR T1 - Timing and synchrony of parturition in Alaskan caribou AN - 16548355; 4329270 AB - Timing of parturition of caribou (Rangifer tarandus) varies within populations, but the relative influences of nutritional condition of females during the autumn breeding season and during gestation on that variation is not known. We determined timing of parturition of caribou in Denali National Park, Alaska, during 1984-1995, which had wide variation in snowfall that influenced nutritional condition and productivity of females. The first young were observed each year between 4 and 15 May. Annual median dates of parturition for radiocollared females during 1987-1995 varied from 13 to 21 May. Synchrony of births (i.e., proportion of births during 7 days centered on the median date) did not vary significantly among years (P > 0.05). Females less than or equal to 4 years old were more likely to give birth after the annual median date than older females (P = 0.005). Dates of parturition were significantly correlated with masses of females in the previous autumn (P = 0.034) but not in late winter (P = 0.155). Births tended to be earlier for parous females that were not lactating during the previous breeding season compared to those that were lactating (P = 0.030). Annual onsets of parturition varied significantly with snowfall in late winter prior to conception (P = 0.012) but not with snowfall during gestation. Timing of parturition in our study appeared to be a function of physical condition of breeding females in autumn.

A transect consisting of three plots was established down one north- and one south-facing slope in stands representing the typical elevational sequence of tree species. Tree species included subalpine fir (Abies lasiocarpa), Douglas-fir (Pseudotsuga menziesii), mountain hemlock (Tsuga mertensiana), and Pacific silver fir (Abies amabilis). Air and soil temperature, precipitation, and soil moisture were measured during three growing seasons. Snowmelt patterns, soil carbon and moisture release curves were also determined. The plots represented a wide range in soil water potential, a major determinant of tree species distribution (range of minimum values = -1.1 to -8.0 MPa for Pacific silver fir and Douglas-fir plots, respectively). Precipitation intercepted at plots depended on topographic location, storm direction and storm type. Differences in soil moisture among plots was related to soil properties, while annual differences at each plot were most often related to early season precipitation. Changes in climate due to a doubling of atmospheric CO sub(2) will likely shift tree species distributions within, but not among aspects. Change will be buffered by innate tolerance of adult trees and the inertia of soil properties.

Twenty simulations of the Rhea model were performed using 'optimal' parameter sets determined for 10-kilometer (km) grids (10-km by 10-km grid cells) through stochastic calibration. Comparisons of Rhea-model simulations of winter precipitation with April 1 snowpack accumulations at 32 snowcourse stations were performed for the years 1972-1990. For most stations and most years the Rhea model reliably simulates the temporal and spatial variability in April 1 snowpack accumulations. However, in general, the Rhea-model underestimates April 1 snowpack accumulations in the Gennison River basin area, and the underestimation is greatest for locations that receive the largest amount of snow. A significant portion of the error in Rhea-model simulations is due to the calibration of the Rhea model using gauge-catch precipitation measurements which can be as much as 50 percent below actual snowfall accumulations. Additional error in the Rhea-model simulations is a result of the comparison of gridded precipitation values to observed values measured at points.

Major Safety of Dams (SOD) embankment modifications were constructed in 1947, 1994 and 1996 to address concerns related to seepage through the dam, foundation and right abutment. In addition, the spillway, an uncontrolled overflow structure was deemed to be inadequate. The tapered 627-foot (191 meter) long, trapezoidal-shaped chute lacked any energy dissipating structure and with a capacity of 11,200 cfs (cubic feet per second) (317 cms [cubic meters per second]) was unacceptably under sized for extreme flood flows. Three remediation options were considered: 1. A replacement spillway founded on the center of the repaired embankment; 2. Modifying the existing left abutment spillway chute and adding a new formed concrete hydraulic-jump stilling basin; or 3. Modifying the existing spillway and adding a roller compacted concrete (RCC) stilling basin. Foundation geology was the major factor in the selection of the final design. Critical criteria included: avoiding the right abutment landslide which was already considered the source of many of the seepage problems at the site; protecting local aquifers from contamination or exposure through erosion; consideration of uplift pressures during high reservoir levels concurrent with spillway operation; and assuring that adequate foundation strengths were available to support the new stilling basin. The final design called for rehabilitating the existing chute and adding a three stage RCC stilling basin with a capacity of 15,000 cfs (425 cms). The left side and floor of the stilling basin were founded on John Day Tuff (Tjdt) while the right side was founded on Alluvial Fan (Qaf) deposits and compacted fill.

Foundation units consist of a massive landslide, talus/alluvial fan complex, alluvium, and John Day Formation. Upstream right-abutment treatment in 1921 reduced this seepage from an estimated 43 cfs (1.2 m (super 3) /s) to approximately 28 cfs (0.8 m (super 3) /s). Further modifications were completed in 1950 to increase embankment stability, decrease seepage, and provide additional flood protection downstream; further reducing seepage to approximately 12 cfs (0.3 m (super 3) /s). As part of the U.S. Bureau of Reclamation's dam safety program, geotechnical investigations were started in 1985. The right abutment was discovered to be a massive landslide. Following this program, erratic piezometer readings in 1989 and additional sinkholes along the upstream right abutment led to water restriction and construction of a right-abutment geomembrane liner in 1990. Further deteriorating conditions led to draining the reservoir in 1993. Extensive modifications, including an upstream zoned embankment with graded filters and drainage system exiting through maximum section of the original embankment, were completed in 1995. First-filling criteria were instituted following these modifications. On May 17, 1995, turbid flow was noted in the main drain outflow with drainage increasing from 1,770 (112 L/s) to 3,600 gpm (227 L/s) and peaking at 4,000 gpm (252 L/s) on May 22; accompanied by a dramatic rise in pore pressure and increased flows from right-abutment weirs. Extensive underwater examinations and a fluorescein tracer dye testing program resulted in discovery of a 10-foot (3.0-m) diameter sinkhole in the upstream embankment. The sinkhole was backfilled and the reservoir was drained for repairs. Forensic investigations indicated complete sinkhole penetration of the newly constructed embankment with extension down to the 1918 hydraulic fill through an unexpected wedge of rockfill from previous modifications. Following these repairs, dam performance has been closely monitored through the 1996 and 1997 irrigation seasons with performance in expected parameters. Spillway modifications were completed in 1997. JF - Proceedings of the Symposium on Engineering Geology and Geotechnical Engineering AU - Carter, Brent H A2 - Schultz, Richard A.

Bureau of Land Management; United States ER - TY - JOUR T1 - Depositional processes and sediment supply in resistant-boundary channels; examples from two case studies AN - 52501372; 1999-018829 AB - Coarse-grained deposits produced by a rare, extreme flood in the Mt. Everest region of Nepal and fine-grained deposits produced by frequent, moderate floods along the Colorado River in and near the Grand Canyon, U.S.A. illustrate a wide range of depositional patterns, processes, and mechanics along resistant-boundary channels. Deposition processes in each of these case studies were strongly influenced by sediment supply. The availability of sediment was an important factor in both case studies in determining the occurrence, location, stability, and sedimentologic characteristics of deposits produced by their respective floods. A glacial-lake outburst flood in the Mt. Everest region of Nepal eroded, transported, and deposited large quantities of boulders, cobbles, pebbles, and sand along the outburst-flood route. Depositional macroforms produced by this flood include: (1) expansion bars at abrupt expansions immediately downstream of constricted reaches, (2) longitudinal bars at local flow expansions along valley margins, (3) point bars along the inner margins of valley bends, (4) pendant bars immediately downstream of obstructions, and (5) imbricate clusters of cobbles and boulders immediately upstream of obstructions. Along the upper 16 km of the outburst-flood route, deposition is more extensive and deposits are thicker, are more poorly sorted, have more finely-skewed distributions, and have a higher percentage of fine-grained sediment than deposits below 16 km. Additionally, deposits along the upper 16 km of the flood route are reverse graded and coarsen in the downstream direction, whereas deposits below 16 km lack grading or are normally graded. These deposit characteristics suggest that the flood waters along the upper 16 km had higher sediment concentrations and were closer to their transport capacity than the flood waters below 16 km. Most resistant-boundary channels are supply limited with respect to entrainment and transport of cobble- and boulder-sized particles during frequent, low to moderate flows. However, superimposed on this supply limited coarse-grained system is a dynamic fine-grained system in which eddy bars along the channel margins are eroded and redeposited during the rising limb of a given flood. Eddy sand bar deposits along the Colorado River in and near the Grand Canyon are an excellent example of this dynamic erosional and depositional cycle that occurs during frequent, moderate floods. The erosional and depositional cycle of eddy bars during a given flood is strongly controlled by sediment delivered to the plunge pool adjacent to the eddy bar. Sediment delivered to the plunge pool on the rising limb of the flood alters the flow patterns and hydraulics in the pool and causes the eddy bar to scour. As discharge increases, plunge pools are scoured and deposition resumes in the recirculating eddies. If fine-grained sediment supply is reduced along a river because of flow regulation structures, this dynamic cycle of erosion and deposition associated with pools and eddy sand bars no longer occurs and the eddy bars become stable.

Correlating stratigraphic sections makes it possible to estimate the rate and pattern of glacial lacustrine deposition. In stratigraphic sections consisting of silt/clay rhythmites, interpreted as varves, the temporal pattern of deposition resulted in 66 distinctive "packets" that thin upsection over about 3240 to 3610 years. These packets have thick silt beds, a few centimeters to more than three meters thick, at the base, that thin towards the top of the packet. The packets are topped by an average of 20 to 45 microvarves that are about 1 to 5 mm thick. This stratigraphy shows that sedimentation in glacial Lake Missoula was highly variable and episodic. In general, rapid deposition ranging from an average of 11 to 81 cm/yr follows 20 to 45 years of slower sedimentation on the order of millimeters. After this rapid deposition, the rate drops off for 10 to 20 years to slow but constant levels. The average depositional rate for varves ranges from about 1.2 to 3.9 cm/yr with a maximum of 320 cm/yr. The depositional rate for diamict is about twice this fast. This stratigraphy is best explained as a record of episodic instability of the Flathead lobe and probably to a lesser degree the alpine glaciers. Roughly every 30 to 60 years surging and calving of the glaciers resulted in a tremendous increase in sedimentation. The difference between the 1 to 5 mm microvarves, and thickest varves in a packet, on average 11 to 81 cm, is most pronounced for about the first 1100 years and decreases through the following 2000 years. This is probably related to rising lake level and the dynamics of the Flathead lobe.

Taking Hanqiao mine in Xuzhou as an example, this paper introduces a new reclamation method suitable for subsided lands (caused by coal) mining with high phreatic in eastern China. The new method consists of two aspects; on the one hand a non-infilling method which mainly uses a dredging approach and, on the other hand biological reclamation in a beneficial pattern which mainly makes use dykes and ponds. The new engineering and biological reclamation measures, presented in this paper, have been used widely in Xuzhou mining areas. Considerable economic benefits, social and environmental effects have been obtained and these are associated with successful land reclamation in mining areas.

Stream hydrograph analysis was used to calculate natural groundwater recharge and discharge rates. Yearly continuous discharge hydrographs were obtained for 16 watersheds in the Cumberland Plateau area of Tennessee. Baseflow was separated from storm runoff using computerized hydrograph analysis techniques developed by the USGS. The programs RECESS, RORA, and PART were used to develop master recession curves, calculate ground water recharge, and ground water discharge respectively. Station records ranged from 1 year of data to 60 years of data with areas of 0.67 to 402 square miles. Calculated recharge ranged from 7 to 28 inches of precipitation while ground water discharge ranged from 6 to 25 inches. Baseflow ranged from 36 to 69% of total flow. For sites with more than 4 years of data the median recharge was 20 inches/year and the 95% confidence interval for the median was 16.4 to 23.8 inches of recharge. Water budget calculations were also developed independently by a mining company in southern Tennessee. Results showed about 19 inches of recharge is available on a yearly basis. A third method used spoil water discharge measurements to calculate average recharge rate to the mine. Results showed 21.5 inches of recharge for this relatively flat area strip mine. In a further analysis it was shown that premining soil recharge rates of 19 inches consisted of about 17 inches of interflow and 2 inches of deep aquifer recharge while postmining recharge to the spoils had almost no interflow component. OSM also evaluated underground mine inflow data from northeast Tennessee and southeast Kentucky. This empirical data showed from 0.38 to 1.26 gallons per minute discharge per unit acreage of underground workings. This is the equivalent to 7 to 24 inches of recharge per year. The four methods provide a good comparative way to quantify the groundwater portion of the hydrologic balance.

These tests (primarily slug tests) were used to determine the range, variability, and predictability of surface mine spoil hydraulic properties (hydraulic conductivity and transmissivity). Test results show that hydraulic properties of mine spoil aquifers are highly variable and relatively unpredictable. Hydraulic conductivity ranged over 7 orders of magnitude from a very low permeability of 4.45X10 (super -9) m/s to a highly transmissive 7.58X10 (super -2) m/s. The hydraulic conductivity measured at mines with 5 or more wells frequently ranged over 3 orders of magnitude and none ranged less than one. A few statistical relationships between geologic and mining conditions and the hydraulic properties were observed. Spoil aquifers that were under 30 months old and those over 100 months old exhibited significantly lower (95 percent confidence level) hydraulic conductivities than those between 30 and 100 months old. The influence of spoil lithology on the hydraulic conductivity does not appear to be strong, probably because of masking by other factors introduced during reclamation. No significant trends were observed between spoil thickness and hydraulic conductivity. A comparison of hydraulic conductivity derived from slug and constant-discharge tests performed on the same wells indicate that slug tests tend to yield lower values. A few spoil wells exhibited an oscillatory water-level response during slug testing, similar to that observed during testing of some karst and glacial aquifers.

To be effective, these agencies have established common terms and definitions, as well as a method for evaluating the condition of these areas, which has been extensively reviewed and tested. This method involves assessing whether an area is in proper functioning condition (see BLM's TR 1737-9). The method for assessing PFC is a qualitative, yet science-based process that considers both abiotic and biotic factors as they relate to physical function. It facilitates communication about the condition of a riparian-wetland area and focuses attention on the physical process before considering values. A standard checklist is used to ensure consistency in reporting the condition of riparian-wetland areas. The PFC method is straightforward: review existing documents, analyze the PFC definition, and assess functionality using the checklist. The assessment requires the use of an ID team. To assess the condition of a riparian-wetland area, an ID team has to understand its capability and potential and identify the attributes and processes that transpire. If an ID team does not spend the time to develop this understanding, their judgement about PFC will be incomplete and may be incorrect. Riparian-wetland areas are rated in four categories: proper functioning condition, functional--at risk, nonfunctional, and unknown. The condition of some riparian-wetland areas will be relatively easy to discern, while the condition of others will be less evident. Occasionally, items on the checklist will have to be quantified to determine how they should be answered. There are numerous ways these items can be quantified, including those summarized in this document. For areas that are functional--at risk, trend should be identified, as it is a key consideration in interpreting data. At-risk areas with a downward trend are often the highest management priority because a decline in resource values is apparent. Yet these areas often retain much of the resiliency associated with a functioning area. There is usually an opportunity to reverse this trend through changes in management. At-risk areas with an upward trend are often a priority for monitoring efforts. Monitoring these areas assures that they continue to improve. Conversely, trend is not determined for areas that are nonfunctional. While these areas could theoretically still be in decline, most of the riparian values have already been lost. The presence of sufficient riparian-wetland attributes and processes to warrant a determination of trend usually results in a rating of functional--at risk. It is common for an area in PFC to continue to have an upward trend. Many sites that are properly functioning must continue to improve to meet site-specific objectives. However a downward trend may put the area at-risk. Once proper functioning condition is reached, trend relates to specific objectives. The lack of specific information will place many riparian-wetland areas into the category of unknown. It is imperative that areas for which no data exists be evaluated and added to the data base. As information is acquired and resource values are identified, best management practices need to be set in motion. Successful management strategies have to address the entire watershed, as upland and riparian-wetland areas are interrelated and cannot be considered separately. To manage riparian-wetland areas successfully requires a state of resiliency that allows an area to hold together during frequent high-flow events. When a riparian-wetland area's physical aspects are in working order, then channel characteristics are maintained that sustain the area's ability to produce values. Function comes first, then values (desired condition). Managing riparian-wetland areas does not cease once PFC is achieved--it has just started. Existing and potential resource values and the plant communities necessary to support these values have to be identified. Once these values have been identified, then specific objectives can be derived to ascertain desired condition. Management actions to achieve desired condition can then be designed and set in place.

Significantly larger amounts of this substance were found in extracts of outer dorsal skin layers from both UVB-sensitive and UV B-tolerant fish when compared with extracts of inner dorsal skin layers.

As a result, positive benefits from recreation must be demonstrated to justify public expenditures for recreational facilities. This paper presents estimates of the benefits from North Dakota river recreation and identifies the primary characteristics that influence those benefits. Three separate models are examined: (1) a survey participation model that is used to correct for nonresponse bias, (2) a recreation participation model that estimates the factors affecting the decision of an individual to participate in river recreation, and (3) a travel cost model that estimates the factors affecting the number of trips an individual will take to a river recreation area. The benefits of North Dakota river recreation are estimated by the travel cost model to average about $32.50 per visit and about $114 million annually. The three models are also used to demonstrate the potential recreational benefits from improved North Dakota river water quality.

Smolting is an adaptive specialization for downstream migration, seawater entry, and marine residence. While still in fresh water, smolts become silvery and streamlined, lose their positive rheotaxis and territoriality, and begin schooling. Physiological changes include increased salinity tolerance, olfactory sensitivity, metabolic rate, scope for growth, and altered hemoglobin and visual pigments. Through their impact on the neuroendocrine system, photoperiod and temperature regulate physiological changes, whereas temperature and water flow may initiate migration. Smolt survival is affected by a limited period of readiness (a physiological "smolt window") and the timing of seawater entry with environmental conditions such as temperature, food, and predators (an ecological "smolt window"). Smolt development is adversely affected by acidity, pollutants, and improper rearing conditions, and is often more sensitive than other life stages. Unfortunately, the migration corridor of smolts (mainstems of rivers and estuaries) are the most heavily impacted by pollution, dams, and other anthropogenic activities that may be directly lethal or increase mortality by delaying or inhibiting smolt migration.

We analyzed existing annual survey data for the White-faced Ibis breeding in the Great Basin and surrounding area for 1985-1997. Methods varied among colonies and included flight-line counts and fixed-wing aircraft and helicopter surveys. The number of White-faced Ibis breeding pairs in the Great Basin area has nearly tripled since 1985, despite years of severe flooding and drought at major breeding areas. This growth is reflected in both peripheral (i.e., Oregon, California, Idaho) and core (i.e., Nevada and Utah) components of the population. Our data on colony dynamics in Oregon and Nevada illustrate the ability of the highly nomadic White-faced Ibis to compensate for poor conditions at traditional colony sites by moving among colonies and rapidly colonizing newly available wetlands. We suggest that the White-faced Ibis would benefit from a landscape mosaic of well-distributed peripheral wetlands and persistent colony sites. The nomadic nature of the White-faced Ibis and the dynamic nature of their breeding habitat necessitates that wetland management decisions and population monitoring be conducted in a regional context.

No previous quantitative assessments had been made of diets of this species anywhere along the Atlantic Coast, and only a few observations had been reported from other coastal areas in the southern United States. During 80 h of observations over the two seasons, 757 feeding observations were made, primarily at two colony sites. We examined how prey type (fish, marine invertebrates, terrestrial prey) and size were influenced by year, tide cycle, season (early and late) and age of the young (small chicks 7 d). We did not find significant year differences, but all other factors revealed statistically significant results. Older (>7 d) chicks were fed relatively more terrestrial and marine invertebrate prey than were younger chicks. In June (early season), fewer fish and terrestrial prey were fed to chicks than later (July-August). Most prey were less than one bill length in size, with the majority of the smallest prey being marine invertebrates. Tide cycle influenced prey delivered with terrestrial prey becoming relatively more important during high and ebb periods than during low and flood tides when aquatic prey dominated. The major marine invertebrate prey taken was the fiddler crab (Uca spp.). Terrestrial prey consisted mostly of large odonates and orthopterans. Unlike earlier reports from Europe, we found no regurgitated food pellets in any of the colonies in either year. This study confirms that the Gull-billed Tern is an extremely opportunistic feeder and has adapted to a variety of habitats, helping to explain its cosmopolitan distribution.

Freshwater bivalves were collected from the Ohio River in November 1995 and June and September 1996. In all 190 animals were sampled, some from their native Ohio River water (day 0) and others after relocation to a different water supply. Sampling and bacterial isolation techniques are described. The mean total bacteria counts were about 1.6 x 10 super(5) CFU/g of bivalve soft tissue, and this remained relatively stable during the 30-day period, yet the distribution was dynamic. Flavobacterium columnare, a salmonid fish pathogen, was isolated from one Amblema plicata of a day 0 sample in June 1996 but not after relocation to a different water source.

Stream insects appear to respond to both spatial and temporal variation in physical heterogeneity. At all spatial scales, the data largely support the idea that physical complexity promotes biological richness, although exceptions to this relationship were found. These exceptions may be related to how we measure habitat complexity at finer spatial scales and to factors that influence regional richness, such as biogeographic history, at broader spatial scales. However, the degree to which local stream insect assemblages are influenced by regional processes is largely unknown.

Birds, bats, and reptiles were affected, and by 1990 most forested areas on Guam retained only three native vertebrates, all of which were small lizards. Of the hypotheses to account for the severity of this extinction event, we find some support for the importance of lack of coevolution between introduced predator and prey, availability of alternate prey, extraordinary predatory capabilities of the snake, and vulnerabilities of the Guam ecosystem. In addition, there were important interactions among these factors, especially the presence of introduced prey (possessing coevolutionary experience) that were thus able to maintain their populations and provide alternate prey to the introduced predator while it was driving the native prey species to extinction. This complex of vulnerabilities is common on oceanic islands.

The method is based on the discrete-time formulation of wave propagation in layered media for vertically propagating plane shear waves. Buildings are modeled as an extension of the layered soil media by assuming that each story in the building is another layer. The seismic response is expressed in terms of wave travel times between the layers, and the wave reflection and transmission coefficients at layer interfaces. The calculation of the response is reduced to a pair of simple finite-difference equations for each layer, which are solved recursively starting from the bedrock. Compared with commonly used vibration formulation, the wave propagation formulation provides several advantages, including the ability to incorporate soil layers, simplicity of the calculations, improved accuracy in modeling the mass and damping, and better tools for system identification and damage detection.

Recent changes in rice harvesting methods (i.e., use of stripper-headers) and a legislative mandate to decrease burning of rice straw after harvest may alter habitat availability and use. Thus, we investigated species richness and community composition of nonbreeding waterbirds during October-March 1993-94 and 1994-95 in rice fields of the northern Sacramento Valley. Most (85-91% of land area) rice was conventionally harvested (i.e., cutter bar), and the remainder was stripped. Rice straw was left untreated in more than half of fields (52% in 1994 and 54% in 1995), especially in stripped fields (56-70%). In fields where farmers treated straw, the most common management methods were plowing (15-21%), burning (19-24%), and chopping (3-5%). Fields became increasingly wet from October through March as seasonal precipitation accumulated and farmers flooded fields to facilitate straw decomposition and provide habitat for ducks. Species richness of waterbirds was greater (P 0.23). Species richness in stripped fields probably was low because foraging opportunities were limited by tall dense straw, decreased grain density, and infrequent flooding. We recommend that land managers wishing to provide habitat for a diverse waterbird community harvest rice using conventional methods and flood fields shallowly.

Water birds with herbivorous diets have been less thoroughly examined. The concentrations of trace elements in the livers and the esophageal contents of an herbivorous water bird, the American coot (Fulica americana) were measured to compare levels of contaminant exposure among different locations in the Bay system and with other water birds. A total of 39 coots were collected from four sites: Napa River and Mare Island Strait in the north, Berkeley in the middle, and Coyote Creek in the south. Livers of Berkeley samples differed significantly from those of Napa River and Mare Island Strait by their greater concentrations of As and B and lower concentrations of Cu, but they seemed to be within normal ranges for birds. Otherwise the concentrations of trace elements in the livers did not differ among sites. Ingesta samples from Berkeley differed from the other sites because they tended to be higher in Al, V, and Zn. In contrast to waterfowl, livers from the herbivorous coots in San Francisco Bay showed little exposure to Cd, Hg, Pb, or Se. Coot ingesta showed few samples with measurable levels of Cd, Hg, or Se and had low levels of Pb. The herbivorous diet of coots may shield them from exposure to such elements. However, high levels of V were present in coot livers and ingesta from all four sites, suggesting adaptation to this toxic element.

Experimental habitat management consisted of short-rotation clearcutting of 1-ha forest patches to create various-aged forest stands of mixed oak (Quercus spp.) and aspen (Populus tremuloides, P. gradidentata)/scrub oak (Q. Ilicifolia, Q. prinoides). Home range size was not significantly different between grouse occupying managed and an adjacent unmanaged forest. Female grouse with broods selected mixed oak/scrub oak habitats and avoided herbaceous areas, recent clearcuts, and pitch pine (Pinus rigida)/scrub oak habitats throughout the study area. on the managed area, grouse selected 10-yr-old clearcut patches in mixed oak and aspen/scrub oak. Sites used by grouse had higher densities of woody stems 2.5-7.5-cm dbh, greater % cover of live vegetation at 0-2 m, and were closer to edges and openings than random sites. Habitat management practices positively affected one microhabitat component, distance to nearest edge, that was selected by female grouse with broods.

A prototype metering pump was developed by U.S. Bureau of Reclamation personnel to deliver a constant low dose of herbicide in response to the variable flow rates often experienced in these canal systems. Residue analyses indicated that target herbicide rates were closely approximated through 84 hr in the Idaho study, with a resultant 97% reduction of sago pondweed biomass along the 1.6-km treatment site at 28 days posttreatment. In contrast, biomass at untreated control sites remained near pretreatment levels of 120 g dry weight/m super(2). Target endothall concentrations were maintained through 55 hr at the Colorado site, followed by an unexplained drop in endothall levels to one half the target concentration through 84 hr. Biomass reductions of 60 to 98% were recorded along the 5.3 km treatment site by 17 days posttreatment. Results demonstrated that the low-dose, extended exposure concept for endothall treatment was efficacious and logistically feasible. In addition, the newly developed metering pump may have great utility for herbicide application in high-flow environments of the western United States.

Gill nets and bottom trawls were used to catch lake trout in fall 1994 and 1995 from two nearshore sites and Sheboygan Reef. Each lake trout was judged immature or mature, based on visual examination of gonads. Probit analysis, coupled with relative potency testing, revealed that age-at-maturity and length-at-maturity were similar at the two nearshore sites, but that lake trout from the nearshore sites matured at a significantly earlier age than lake trout from Sheboygan Reef. However, length at maturity for the nearshore populations was nearly identical to that for the offshore population, suggesting that rate of lake trout maturation in Lake Michigan was governed by growth rather than age. Half of the lake trout males reached maturity at a total length of 580 mm, whereas half of the females were mature at a length of about 640 mm. Over half of nearshore males were mature by age 5, and over half the nearshore females matured by age 6. Due to a slower growth rate, maturity was delayed by 2 years on Sheboygan Reef compared with the nearshore populations. Documentation of this delay in maturation may be useful in deciding stocking allocations for lake trout rehabilitation in Lake Michigan.

ER - TY - JOUR T1 - Bacillus arsenicoselenatis, sp. nov., and Bacillus selenitireducens, sp. nov.: two haloalkaliphiles from Mono Lake, California that respire oxyanions of selenium and arsenic AN - 1665491714; 5376931 AB - Two gram-positive anaerobic bacteria (strains E1H and MLS10) were isolated from the anoxic muds of Mono Lake, California, an alkaline, hypersaline, arsenic-rich water body. Both grew by dissimilatory reduction of As(V) to As(III) with the concomitant oxidation of lactate to acetate plus CO2. Bacillus arsenicoselenatis (strain E1H) is a spore-forming rod that also grew by dissimilatory reduction of Se(VI) to Se(IV). Bacillus selenitireducens (strain MLS10) is a short, non-spore-forming rod that grew by dissimilatory reduction of Se(IV) to Se(0). When the two isolates were cocultured, a complete reduction of Se(VI) to Se(0) was achieved. Both isolates are alkaliphiles and had optimal specific growth rates in the pH range of 8.5-10. Strain E1H had a salinity optimum at 60 g l-1 NaCl, while strain MLS10 had optimal growth at lower salinities (24-60 g l-1 NaCl). Both strains have limited abilities to grow with electron donors and acceptors other than those given above. Strain MLS10 demonstrated weak growth as a microaerophile and was also capable of fermentative growth on glucose, while strain E1H is a strict anaerobe.

We estimated breeding and natal dispersal in two studies of a population of the Puerto Rican Vireo (Vireo latimeri) that is in danger of local extirpation due to low reproductive success. From 7.1-29% of adult males and 12.5-25% of adult females changed territories between breeding seasons. The median breeding dispersal distance of 12 birds (7 males, 2 females, and 3 of unknown sex) was 370 m (range 110-560 m). Four fledglings dispersed a median distance of 490 m from their natal nests to breeding territories (range 300-2030 m). The implications of these data for population trends of the vireo in Guanica Forest are discussed.

The eggs were artificially incubated until pipping and were then analyzed for organochlorines, mercury, and selenium. Livers of embryos were analyzed for hepatic microsomal ethoxyresorufin-O-dealkylase (EROD) activity. Brains were measured for asymmetry. Egg-laying began in early April and the mean clutch size was 4.2 eggs per clutch. Organochlorine concentrations were generally low (geometric mean p,p'-DDE = 1.6 mu g/g wet weight, polychlorinated biphenyl [PCB] = 4.9 mu g/g), however, one egg had elevated concentrations of p,p'-DDE (13 mu g/g) and PCBs (56 mu g/g). EROD activity in the embryos analyzed from INDU was not elevated. The frequency (11%) of brain asymmetry was low. Eggshells averaged 3.4% thinner than eggshells collected prior to the use of DDT. Mercury (geometric mean = 0.9 mu g/g dry weight) concentrations in GBH eggs were within background levels. Selenium (4.0 mu g/g dry weight) concentrations in eggs were above background levels, but below a concentration threshold associated with reproductive impairment.

The distribution of these services to guarantee their effective utilization is another focus of concern. As citizens are heterogeneous in character, their access to urban public services is affected by the distribution of those services. Access to some services with fixed facilities is limited by the location of the service within a city. In this study, which focuses on the city of Ankara, Turkey, the parks and recreational facilities are evaluated in terms of both service and user characteristics. Since the service has a merited reputation due to the public and its free provision, a local government aiming for a just distribution claims to distribute the service 'equally' on a geographical basis. This study evaluates the current policy and proposes distributional justice to achieve a truly equitable distribution, which is sensitive to the characteristics of different citizen groups, instead of the territorial justice (i.e. park distribution based on geography) that cannot satisfy the conditions of effective utilization.

We present a total of nine additional unreported species for Roaring Springs Cave, bringing the total known invertebrate fauna for this cave to 19 species. The fauna can be divided into a shallow cave group of species, presumably troglophilic or "accidental", a middle cave fauna, and a single, deep-cave troglobitic amphipod. The amphipod is an undescribed, apparently endemic species in the genus Stygobromus. This is the first report of aquatic invertebrates from caves in the northern Arizona area.

This paper provides suggestions for future applications of mesocosm research. Attention should be given to the configuration of mesocosm parameters to explicitly study regional questions of ecological interest. The initial physical, chemical, and biological conditions within mesocosms should be considered as factors shaping the final results of experiments. Certain fundamental questions such as the ecological inertia and resilience of systems with different initial ecological properties should be addressed. Researchers should develop closer working relationships with mathematical modelers in linking computer models to the outcomes of mesocosm studies. Mesocosm tests, linked with models, could enable managers and regulators to forecast the regional consequences of chemicals released into the environment.

At different times, these probes variously recorded pressure-temperature-time conditions (to nearly 22 m depth), and video probes showed the conduit geometry and processes of recharge (to 13 m depth). Temperatures recorded were, within experimental error, the same as those recorded in 1942, with a peak bottom temperature (T) of 118 degrees C. Processes observed include fog formation in the upper levels of the conduit owing to wind and entrainment of cool air; "bank storage" of hot water that splashes to high levels, cools, and recharges; recharge of cooler ground water into the conduit; superheated steam expansion into the conduit (T = 129.5 degrees C); periodic temperature fluctuations; and exsolution of bubbles of noncondensable gas, which we propose are CO (sub 2) .

Regression models that related mallard densities to habitat suitability indices accounted for only 29% of the variability in the data and the 95% confidence interval of predicted mallard densities included zero for most habitat suitability indices evaluated. Thus, we conclude that the published HSI model is a poor predictor of wintering mallard density in the Lower Mississippi Valley. We suggest model revision to allow users to remotely obtain model inputs for habitat characteristics at landscape scales. Further, we suggest the model be revised to consider yearly variation in habitat and flood conditions that better reflect the ability of an area to support wintering mallards.

For example, traditional habitat selection analysis methods do not use information about the size and distribution of the several patches of each cover type that may exist within the study area. Statistical tests are presented for hypotheses about disproportional use of cover types and patches within cover types. These tests require that use of individual patches is recorded, as well as the size of individual patches. Different designs are considered in which there are (1) single or multiple samples of use, and (2) equal or unequal habitat availability. Formulas for calculating Type II statistical errors of the tests are presented and Monte Carlo simulation is used to assess the accuracy of the formulas and to check the Type I error rates of the proposed test statistics. With adequate sample sizes, Type II error formulas can be a useful tool for planning of habitat selection studies. An example analysis is presented of a hypothetical study of habitat selection by ring-necked pheasants (Phasianus colchicus) in a Midwestern landscape. The proposed tests also represent a contribution toward bringing together concepts of landscape ecology and wildlife habitat selection.

Change in total extent was evaluated through a map to map comparison of data interpreted from a 1978 Landsat multi-spectral scanner image and 1987 black and white aerial photographs. A ground survey in 1995 was used to assess spatial change from 1987. Eelgrass beds were the predominant vegetation type in the lagoon, comprising 44-47% (15 000-16 000 ha) of the total area in 1978 and 1987. Izembek Lagoon contains the largest bed of seagrass along the Pacific Coast of North America and largest known single stand of eelgrass in the world. There was a high degree of overlap in the spatial distribution of eelgrass among years of change detection. The overall net change was a 6% gain between 1978 and 1987 and a < 1% gain between 1987 and 1995.

Presettlement middens consistently contained abundant macrofossils of plant species palatable to large herbivores that are now absent or reduced, such as winterfat (Ceratoides lanata) and ricegrass (Stipa hymenoides). Macrofossils and pollen of pinyon pine (Pinus edulis), sagebrush (Artemisia spp.) and roundleaf buffaloberry (Shepherdia rotundifolia) were also recently reduced to their lowest levels for the 5400-yr record. Conversely, species typical of overgrazed range, such as snakeweed (Gutierrezia sarothrae), viscid rabbitbrush (Chrysothamnus visidiflorus), and Russian thistle (Salsola sp.), were not recorded prior to the historic introduction of grazing animals. pollen of Utah juniper (Juniperus osteosperma) also increased during the last 200 yr. These records demonstrate that the most severe vegetation changes of the last 5400 yr occurred during the past 200 yr. The nature and timing of these changes suggest that they were primarily caused by 19th-century open-land sheep and cattle ranching. The reduction of pinyon and sagebrush concurrent with other grazing impacts suggests that effects of cattle grazing at modern stocking levels may be a poor analog for the effects of intense sheep grazing during drought.

Decomposition ofSpartina patens shoot and leaf material was studied by using litter bags in mesohaline marshes in the Barataria and Terrebonne basins of coastal Louisiana.Spartina patens decomposed very slowly with an average decay constant of 0.0007, and approximately 50% of the material remained after 2 years in the field. Material at the Barataria site decomposed faster than did Terrebonne material with trend differences apparent during the first 150 days. This difference might be explained by the higher content of phosphorus in the Barataria material or a flooding period experienced by the Barataria bags during their first 10 days of deployment. Nitrogen and carbon content of the plant material studied did not differ between the two basins. We detected no consistent significant differences in decomposition above, at, or below sediment/water level. BecauseS. patens is the dominant plant in these marshes, and because it is so slow to decompose, we believe thatS. patens shoots are an important addition to vertical accretion and, therefore, marsh elevation.

Changes in netSpartina production, and porewater and solid phase chemistry of treated cores were compared to natural conditions in the field collection site over a 21-mo period. Net production among treatments increased significantly in drained and waterlogged peat compared to field conditions during the first growing season. Constantly high sulfide in waterlogged cores accompanied reduced plant growth. Aeration invigorated growth in draimed cores but led to oxidization of sulfide minerals and to lowered pH. During the second growing season, growth declined in the drained treatment, probably because of acidification and decreased dissolved inorganic nitrogen. Results are pertinent to the success of current wetland protection and restoration activities in the coastal zone.

EMA can utilize three types of at-site flood information: systematic stream gage record; information about the magnitude of historical floods; and knowledge of the number of years in the historical period when no large flood occurred. EMA employs an iterative procedure to compute method-of-moments parameter estimates. Initial parameter estimates are calculated from systematic stream gage data. These moments are then updated by including the measured historical peaks and the expected moments, given the previously estimated parameters, of the below-threshold floods from the historical period. The updated moments result in new parameter estimates, and the last two steps are repeated until the algorithm converges. Monte Carlo simulations compare EMA, Bulletin 17B's [United States Water Resources Council, 1982] historically weighted moments adjustment, and maximum likelihood estimators when fitting the three parameters of the log-Pearson type III distribution. These simulations demonstrate that EMA is more efficient than the Bulletin 17B method, and that it is nearly as efficient as maximum likelihood estimation (MLE). The experiments also suggest that EMA has two advantages over MLE when dealing with the log-Pearson type III distribution: It appears that EMA estimates always exist and that they are unique, although neither result has been proven. EMA can be used with binomial or interval-censored data and with any distributional family amenable to method-of-moments estimation. Copyright 1997 by the American Geophysical Union.

In the eastern tropical Pacific (10 degree N to 10 degree S and 140 degree to 90 degree W), seabirds were censused on 16 cruises that followed the same tracks every spring and autumn, 1984 to 1991. This study area possesses closely spaced, well-defined water types and the time period was sufficient to include 2 ENSOs (El Nino-Southern Oscillation) and 1 cold water event (LNSO), thus insuring maximum environmental variability. On the cruises, we measured physical features such as sea-surface temperature (SST) and salinity (SSS) at a coarse scale (1 to 100 km) as well as, at the large scale, the identity of surface water masses and current systems. During spring, at the coarse scale, seabirds were associated mainly with a canonical axis consisting of SST and SSS. During autumn, coarse scale seabird /environment associations were defined by a canonical axis composed of SST and thermocline depth; SSS was of secondary importance. Using SST and SSS optima from the coarse scale analysis, we could predict only the water mass associations for individual species during spring. Consistent between-year associations with water masses were not found in either season. Regardless of season, seabirds at the large scale were associated most consistently with current systems rather than water masses. At the coarse scale, neither the canonical axes nor the seabird associations with these axes were affected by ENSO/LNSO events. At the large scale, seabird associations with currents remained the same during the ENSO/LNSO events for sooty tern, black-winged and white-winged petrels, and wedge-tailed shearwater. Juan Fernandez petrel, wedge-rumped storm-petrel, and Leach's storm-petrel had different associations with currents during the ENSO/LNSO events. We hypothesize that the effect of ENSO/LNSO events on individual species is mitigated by the ability of species to persist in low productivity waters during the non-ENSO/LNSO years.

The Shiny Cowbird (Molothrus bonariensis), a generalist brood parasite native to South America, arrived on the island in 1955 and has established itself as a breeding resident. To determine the impact of the exotic cowbird on vireo reproductive success, I studied the demography of marked Puerto Rican Vireos in Guanica Forest, Puerto Rico, in 1990-1993. Vireo breeding season length varied among years (69-106 days), apparently influenced by rainfall. The primary causes of reproductive failure were nest parasitism and nest predation. Cowbirds parasitized 73-83% of vireo nests. Parasitism reduced the number of vireos fledged per successful nest by 82%, primarily through decreased hatching success and fledging success. Vireos did not abandon nests in response to cowbird egg-laying, but frequently deserted if cowbirds removed host eggs. Native avian predators and exotic mammalian predators together caused the demise of about 70% of all nest attempts. As a result, daily nest survival rate was low (0.93 plus or minus 0.01), and only 13-19% of nests fledged vireo or cowbird young. Pairs renested after failure and attempted to raise second broods. Females in this population attempted two to six nests per season and fledged an average of 1.33 vireos in 1991 and 0.24 vireos in 1993. The combination of restricted breeding season, high predation and parasitism rates, large impact of parasitism on reproductive output, and low seasonal fecundity of females suggests that, despite high survival rates, the Puerto Rican Vireo is in danger of extirpation from portions of its range.

While resident at a stopover, individuals were very localized in their movements. Over 40% of the birds made no inter-wetland movements, and over 90% of individuals moved less than 10 km from their original release site. Characteristics of wetlands where birds were released did not affect bird movements. However, the structure of the surrounding landscape explained up to 46% of variation in individual bird movements. As the distance between wetlands decreased, and the proportion of the landscape composed of wetlands increased, individual birds moved between wetlands more frequently and moved longer distances from their release site. These movement patterns indicate that a more connected landscape allows shorebirds to exploit more feeding sites with reduced searching costs; a result consistent with foraging theory. We estimate a degree of landscape connectivity at which a wetland complex functions as a single large wetland as measured by sandpiper feeding patterns. Our data provide support for the idea that complexes of small, closely spaced wetlands can be important migration stopovers and may have significant conservation value.

The Lake McDonald watershed of Glacier National Park was the focus for two linked research activities: acquisition of baseline data on hydrologic, chemical and aquatic organism attributes that characterize this pristine northern rocky mountain watershed, and further developing the Regional Hydro-Ecosystem Simulation System (RHESSys), a collection of integrated models which collectively provide spatially explicit, mechanistically-derived outputs of ecosystem processes, including hydrologic outflow, soil moisture, and snowpack water equivalence. In this unique setting field validation of RHESSys, outputs demonstrated that reasonable estimates of SWE and streamflow are being produced. RHESSys was used to predict annual stream discharge and temperature. The predictions, in conjunction with the field data, indicated that aquatic resources of the park may be significantly affected. Utilizing RHESSys to predict potential climate scenarios and response of other key ecosystem components can provide scientific insights as well as proactive guidelines for national park management.

Park, McDonald L.; Freshwater ER - TY - JOUR T1 - Excavation of red squirrel middens by grizzly bears in the whitebark pine zone AN - 16120005; 4210173 AB - Whitebark pine seeds Pinus albicaulis are an important food of grizzly Ursus arctos horribilis bears wherever whitebark pine is abundant in the contiguous United States of America; availability of seeds affects the distribution of bears, and the level of conflict between bears and humans. Almost all of the seeds consumed by bears are excavated from middens where red squirrels Tamiasciurus hudsonicus have cached whitebark pine cones. Relationships among the occupancy of middens by squirrels, the excavation of middens by bears, and site features were investigated in this study. Data were collected from radio-marked bears and from middens located from line transects on two study sites in the Yellowstone ecosystem. Densities of active middens were positively related to lodgepole pine Pinus contorta basal area and negatively related to steepness of slope. The probability that a midden was occupied by a squirrel (i.e. active) was positively related to lodgepole pine basal area in the surrounding stand, size of the midden and size of the whitebark pine cone crop, and negatively related to elevation and to bear excavation during the previous 2-12 months. The probability that a midden had been excavated by a bear during the previous 12 months was positively related to size of the midden, and to whitebark pine basal area and cone crop, and negatively related to nearness of roads and town sites. The influence of midden size on bear use was attributable to a positive relationship with the number of excavated cones. The positive association between bear excavations and whitebark pine basal area or cone crops was attributable to availability of pine seeds. Grizzly bears would benefit from the minimization of roads and other human facilities in the whitebark pine zone and from increases in the availability of whitebark pine seeds, potentially achieved by increasing the numbers of cone-producing whitebark pine trees, especially in lower elevations of the whitebark pine zone where red squirrels are more abundant.

These reports provided an excellent overview of the geologic setting and status of production activities for mineral resources, but are now out of date in many areas. Colorado School of Mines has contracted with BIA to produce updated oil and gas atlases for selected reservations on a priority basis to be determined by BIA. In 1995 (updates in 1996), the USGS completed a national oil and gas resource assessment utilizing the "petroleum system" approach to identifying resource potential. This approach forms the foundation for each atlas. Each atlas contains maps and graphical presentations of the geologic setting, available seismic, source and reservoir rock information, trapping mechanisms, present sources of oil and gas production, and predictions for future petroleum resource potential. Atlases are presented in hardcopy output as well as in digital text and graphical formats suitable for viewing on PC desktop computers. The atlases can be used to help determine the remaining resource potential for selected reservations, develop plans for appropriate lease sales, provide an inventory of data that tribes can utilize to attract industry, and develop case studies for use in the Native American Energy and Mineral Institute (NAEMI), operated by Colorado School of Mines. Information from the reservations is being compiled in atlases grouped on a regional basis. The Northern Rocky Mountain Atlas, tentatively to be released in June, 1997, contains Fort Berthold, Wind River, Blackfeet, Fort Peck, Fort Belknap, and Standing Rock reservations. The Southern Rocky Mountain Atlas is to be completed in 1998.

All mallards in the 80 ppm group, three in the 40 ppm group, and one in the 20 ppm group died. Histologic lesions in mallards that died of selenosis were hepatocellular vacuolar degeneration progressing to centrolobular and panlobular necrosis, nephrosis, apoptosis of pancreatic exocrine cells, hypermaturity and avascularity of contour feathers of the head with atrophy of feather follicles, lymphocytic necrosis and atrophy of lymphoid organs (spleen, gut-associated lymphoid tissue, and lumbar lymph nodes), and severe atrophy and degeneration of fat. Histologic lesions in surviving mallards in the 40 ppm group, which had tissue residues of selenium comparable to mallards that died, were fewer and much milder than mallards that died; lesions consisted of atrophy of lymphoid tissue, hyalinogranular swelling of hepatocytes, atrophy of seminiferous tubules, and senescence of feathers. No significant histologic lesions were detected in euthanized mallards in the 0, 10 and 20 ppm groups. Based on tissue residues and histologic findings, primarily in the liver, there was a threshold of selenium accumulation above which pathophysiologic changes were rapid and fatal. Pathognomonic histologic lesions of fatal and nonfatal selenosis were not detected. Criteria for diagnosis of fatal selenosis in aquatic birds include consistent histologic lesions in the liver, kidneys, and organs of the immune system. Although histologic changes were present in cases of chronic non-fatal selenosis, these were inconsistent. Consistent features of fatal and non-fatal chronic selenosis were marked weight loss and elevated concentrations of selenium in organs.

We conducted 1- and 2-choice tests using grains with caged cowbirds and geese, and applications of lime to turf in dry and slurry form for geese. Lime mixed with millet or whole-kernel corn at 25, 12.5, and 6.25% (g/g) reduced cowbird and goose feeding in 4 day, 2-choice (treated or untreated grain) cage trials. Reductions in total food intake occurred for both species during similar 1-choice tests with lime (25% [g/g]) and millet or corn. Body mass of cowbirds and geese increased or remained constant during 2-choice tests. In contrast, body mass declined for both species during 1-choice tests. Application of lime to enclosed 10- x 10-m-grass plots in powder or slurry form at an application rate of 544 kg/ha also reduced goose feeding on treated plots for 2-3 days. Mean numbers of geese and mean fetal mass on control and treated plots were similar during both turf experiments. No phytotoxicity of grass was observed greater than or equal to 40 days posttreatment.

We are presently having success in using detrital-base diets to support consistent growth of young native clams of several species in the laboratory. The base used to form these diets appears to be immaterial if the following conditions are met: (1) the food material must be complete, containing all the essential amino acids, and fatty acids such as linoleic or linolenic. Incomplete forage base either leads to no growth or death; (2) the diet must be pre-digested or rotted before offering it to the clam - fresh diets may be digested, but have limited assimilation, and lead to very inconsistent growth and survival rates; (3) food must be supplied at a rate of at least 4mg /L for at least 12 hours a day, preferably longer; (4) water quality must somehow be maintained. Basically, these diets are actually infusoria cultures, replete with various types of bacteria. Our greatest challenge mains in maintaining water quality. We are presently managing 8000 clams in the laboratory on these diets. Survival of older individuals is excellent, and younger clams are increasing in shell length. The next few months will be critical in determining whether this kind of forage base remains a feasible option in meeting the dietary needs of native clams.

In 1996, 22 native clam species were discovered and relocated from a coastal wetland, Metzger Marsh, just west of Toledo Ohio. Large numbers of zebra mussels of several year classes were colonizing parts of this marsh. Multiple size classes of native clams were also collected for 18 of the 22 species; e.g., A. plicata (6 year classes, size range 10-147 mm), Lampsilis r. luteola (3 year classes, size range 47-123 mm). Many of the clams, such as A. plicata and L. fragilis were gravid when collected. Less than 1% of the 7,000 clams collected showed any degree of zebra mussel colonization, either by actual mussels or remnant byssus threads. Laboratory tests indicate that zebra mussel colonization of the native clams was probably limited due to the soft sediments and high water temperatures characteristic of this wetland habitat encouraging burrowing. The survival and continuing successful reproduction of native clams at this Lake Erie wetland indicates that such sites may provide additional refugia for native clam populations.

Using a nationally consistent plot design, we evaluated the local diversity of trees over 2.5 cm in diameter at breast height (dbh) at 780 1/15-ha plots nationwide by measuring the plot-level species richness (R). Visually evident anthropogenic disturbances (e.g. artificial regeneration, logging, grazing by livestock, and prescribed burning), if any, were recorded on each plot. We classified plots with visually evident anthropogenic disturbance as `disturbed' and the remaining plots as `undisturbed'. In each of the five geopolitical regions, we quantified the difference in mean R between disturbed and undisturbed plots.With the exception of Colorado (5%), between 34 and 55% of forested lands in each region had recorded anthropogenic disturbances. Mean R was significantly higher for undisturbed areas than for disturbed areas in the Northeast and Southeast, with the largest differences occurring in the Southeast. Mean R was greater in undisturbed areas than in disturbed areas in most forest cover types for all regions. These differences were greatest in the loblolly pine (Pinus taeda), oak (Quercus spp.)-hickory (Carya spp.), and oak-pine forest types of the Southeast. The only group for which mean R was significantly greater in disturbed areas was the mixed western hardwoods in California. As expected from previous studies, significant differences between regions in mean R were observed, in both disturbed and undisturbed areas.This study bridges an important gap between site-specific forest studies and remote-sensing studies of the forests of a region. We discuss (1) why combining site-specific studies is not appropriate in most cases for rigorous testing at the regional level and (2) how data for some important site-specific variables are not available from most remotely-sensed data sets. The widespread presence of anthropogenic disturbances in most regions, notably the cutting and planting of pine plantations in the Southeast, is associated with generally lower local species richness of trees. The results warrant further investigation at the regional level in light of recent empirical studies on diversity and ecosystem stability.

AN - 16068428; 4105509 AB - I simulated the annual population cycles of Great Egrets (Ardea alba) at Lake Okeechobee, Florida, to provide a framework for evaluating the local population dynamics of nesting and foraging wading birds. The external forcing functions were solar energy, minimum air temperature, water depth, surface-water drying rate, and season. Solar input controlled the production of prey at moderate to high lake stages, but water area exerted primary control during a two-year drought. Modeling prey production as a linear function of water area resulted in underestimation of prey density during the drought, suggesting that prey organisms maintained high fecundity while concentrated in submerged vegetation at the lakeward fringe of the littoral zone. Simulation confirmed that large influxes of wading birds during the drought were the combined result of a regional refuge response and the availability of concentrated prey. Modeling immigration and emigration as primarily functions of the surface-water drying rate, rather than lake stage, resulted in a closer match of observed and simulated population trends for foraging birds, suggesting that the pattern of surface-water fluctuations was a more important factor than water depth. Simulation indicated an abrupt-threshold response rather than a linear association between foraging efficiency and low temperatures, which reduce activity levels of forage fishes. Great Egret breeder recruitment is primarily a function of prey availability, climate, and hydrologic trends, but simulation confirmed the concurrent involvement of a seasonal or physiological-readiness factor. An attractor function driven by high winter lake stages was necessary to reproduce observed patterns of breeder recruitment, suggesting that Great Egrets initiate nesting based on environmental cues that lead to peak food availability when nestlings are present. Poor correspondence of reproductive effort and nest productivity suggested that the drought compromised the birds' predictive abilities. The need to model breeder recruitment as a function of a maximum rate rather than the size of the local foraging population suggested that birds may nest on the lake even though on-lake foraging conditions are poor. Simulated and observed estimates of egg and hatching production did not match, suggesting that the causes of failure during incubation were complex or more localized than could be accounted for with lakewide hydrologic and climatic data. A forced increase in prey consumption of 12% was necessary to reproduce observed, high levels of nest productivity in 1990, which corresponded to the finding that panhandled fish constituted 10-12% of the biomass fed to Great Egret nestlings that year.

S. Geological Survey, Biological Resource Division. The I&M Program focuses on developing protocols and methodologies to inventory and monitor the natural resources. As one of the I&M prototype parks for tropical/sub-tropical ecosystems, BIRNM has begun standardizing and documenting all types of natural resource data and developing long-term protocols for data management. In 1996, Buck Island Reef Sea Turtle Research Program received funding from the National Park Service's Natural Resource Preservation Program for endangered hawksbill sea turtle research. In conjunction with the I&M Program agenda, part of this funding was dedicated to the development of a relational database for the sea turtle research program.

ER - TY - JOUR T1 - EVALUATION OF PHYSICAL PARAMETERS AS INDICATORS OF NESTING BEACH SELECTION FOR THE LOGGERHEAD SEA TURTLE IN THE TEN THOUSAND ISLANDS OF FLORIDA AN - 21080759; 11276708 AB - Loggerhead sea turtles nest in numerous substrate and beach types within the Ten Thousand Islands of southwest Florida. Nesting beach selection was analyzed on 12 unique islands within this archipelago. Numerous physical characteristics were analyzed in an attempt to identify the interconnectedness or lack thereof of these variables and determine their importance for nesting beach selection in Caretta caretta. These characteristics, collected along transects, include: overall slope, beach slope, slope of offshore approach, beach width and height of canopy. Sand samples from each transect were analyzed for pH, %H sub(2)O, %organic content, %carbonate and particle size (8 size classes). Ordinal aspect of beaches and beach length also were analyzed. These variables were chosen after evaluating the islands, conducting literature searches and soliciting personal communications. All of the variables were analyzed at once, incorporating the nesting data into the analysis. In the Ten Thousand Islands, loggerheads appear to prefer wider beaches that inherently have less slope, and secondarily, wider beaches that have low amounts of carbonate.

Department of the Interior ER - TY - JOUR T1 - Bioavailability of biologically sequestered cadmium and the implications of metal detoxification AN - 16299357; 4214071 AB - The deposit-feeding oligochaete Limnodrilus hoffmeisteri possesses metallothionein-like proteins and metal-rich granules for storing and detoxifying cadmium (Cd). In this study we investigated the bioavailability of Cd sequestered within this oligochaete by conducting feeding experiments with super(109)Cd-labeled oligochaetes and the omnivorous grass shrimp Palaemonetes pugio. We also make predictions on Cd trophic transfer based on oligochaete subcellular Cd distributions and absorption efficiencies of Cd by shrimp. Cytosol (including metallothionein-like proteins and other proteins) and a debris fraction (including metal-rich granules and tissue fragments) isolated from homogenized super(109)Cd-labeled oligochaetes were embedded in gelatin and fed to shrimp. The super(109)Cd absorption efficiencies of shrimp fed these subcellular fractions were 84.8 and 48.6%, respectively, and were significantly different (p <0.001), indicating that super(109)Cd bound in these fractions was not equally available to a predator. Mass balance equations demonstrate that shrimp fed whole worms absorb 61.5% of the ingested super(109)Cd, an absorption efficiency similar to that obtained experimentally (57.1%). Furthermore, the majority of the absorbed super(109)Cd comes from the fraction containing metallothionein-like proteins (i.e. cytosol). super(109)Cd absorbed from the debris fraction probably comes from the digestion of tissue fragments, rather than metal-rich granules. The ecological significance of these findings is that prey detoxification mechanisms may mediate the bioreduction or bioaccumulation of toxic metals along food chains by altering metal bioavailability. Another important finding is that trophic transfer of metal can be predicted based on the subcellular metal distribution of prey.

Results from a numerical climate model indicate that summer dryness and related changes of land-surface water balances are highly sensitive to possible concomitant changes of plant-available water-holding capacity of soil, which depends on plant rooting depth and density. The model suggests that a 14% decrease of the soil volume whose water is accessible to plant roots would generate the same summer dryness, by one measure, as an equilibrium doubling of atmospheric carbon dioxide. Conversely, a 14% increase of that soil volume would be sufficient to offset the summer dryness associated with carbon-dioxide doubling. Global and regional changes in rooting depth and density may result from (1) plant and plant-community responses to greenhouse warming, to carbon-dioxide fertilization, and to associated changes in the water balance and (2) anthropogenic deforestation and desertification. Given their apparently critical role, heretofore ignored, in global hydroclimatic change, such changes of rooting characteristics should be carefully evaluated using ecosystem observations, theory, and models.

Ingestion and growth rates were significantly different among the three species for 10- and 20-mm fish, although differences were weaker for 10-mm growth rates. Incorporating these consumption and growth rate estimates and their parameter errors into a simulation model revealed that differences among species in survival could be detected with as few as 3 samples (model runs) for 20-mm fish at both low and high prey density and for 10-mm fish at low prey density, but that 23 samples would be required to detect differences for 10-mm fish at high prey density. Compared with our 8-h estimates, previous short-term (15-30 min) consumption rate estimates for the same three species overestimated consumption rates for the 20-mm fish but underestimated them for the 10-mm fish. Our results suggest that differences in growth and ingestion among the three species are likely even when fish are 10 mm, but that we may not always be able to detect differences in survival of smaller fish.

The San Juan River area in northwestern New Mexico was one of the areas designated for study. Investigators collected water, bottom-sediment, soil, and biological samples at more than 50 sites in the San Juan River area during 1993-94. Sample sites included (1) sites located within Department of the Interior irrigation project service areas, or areas that receive drainage from irrigation projects; (2) reference sites for comparison with irrigationproject sites; and (3) sites located within the reach of the San Juan River from Navajo Dam to 10 miles downstream from the dam. The types ofhabitat sampled included the main stem of the San Juan River, backwater areas adjacent to the San Juan River, tributaries to the San Juan River,ponds, seeps, irrigation-delivery canals, irrigation- drainage canals, a stock tank, and shallow ground water. The types of media sampled included water, bottom sediment, soil, aquatic plants, aquatic invertebrates, amphibians, and fish. Semipermeable- membrane devices were used as a surrogate medium to sample both air and water in some instances. Sample measurements included concentrations of major ions, trace elements,organochlorine pesticides, polychlorinated biphenyls, polycyclic-aromatic-hydrocarbon compounds, and stable isotopes of hydrogen and oxygen. This report presents tables of physical, chemical, and biological data collected for the U.S. Department of the Interior, National IrrigationWater-Quality Program.

In 1982, the United States Congress enacted the "Indian Mineral Development Act" (IMDA). This law greatly expanded the participation of Native American tribes in the development of their energy and mineral resources. The evaluations of Indian Mineral Development agreements by the Bureau of Indian Affairs (BIA) are performed as assistance to the tribes entering these agreements and as a basis for determining if the agreements meet necessary criteria for Departmental approval. This paper will also discuss issues that are pertinent to doing business on Native American lands.

AN - 52621722; 1998-021748 AB - Federal lands in the United States administered by the Department of Interior, Bureau of Land Management and Department of Agriculture, Forest Service, total about 461 million acres; 191 million acres are administered by the Forest Service, and 270 million acres are administered by the Bureau of Land Management. The vast majority of these public lands are located in the western USA and Alaska. Although some of these lands are withdrawn from the mining and minerals laws for such uses as wilderness and recreation areas, the majority of them are open for mineral exploration and development. Several laws dating back to the late 1800s control the disposition of minerals on Federal lands. The 1872 Mining Law set up a system whereby hardrock minerals (gold, copper, lead, etc.) can be staked under mining claims on public lands. Mining claimants have a statutory right to these "locatable" minerals that occur within their claim boundaries. The 1920 Mineral Leasing Act set aside certain minerals including coal, oil, gas, oil shale, phosphate, and sodium and provided a leasing system for their removal from public lands. The 1947 Materials Act and the 1955 Surface Resources Act were later passed to enable the extraction of "salable" minerals that were never covered under the 1872 Mining Law. The 1947 and 1955 Acts removed common varieties of sand, stone, gravel, pumice, cinders, clay, and petrified wood from the Mining Law, but provided that certain "uncommon varieties" of these same minerals remain locatable under the 1872 Mining Law. Unfortunately, it has been left up to the legal system to define what makes a mineral "common" versus "uncommon." One particular case heard in the 9th Circuit Court of Appeals, McClarty vs. Secretary of the Interior, helped set a standard for determining common or uncommon minerals. The basis of the McClarty criteria is whether the mineral in question has a unique property that gives it a distinct and special value, which in turn, is reflected by the premium price that the mineral commands in the marketplace. Many industrial minerals fall within the uncommon variety definition, while others are considered common. Minerals such as perlite, gypsum, mica, and garnet, to name a few, are easily categorized as locatable minerals because of their unique characteristics and uses. Others, including certain grades of limestone, silica, clay, pumice, building stone, and decorative stone are much harder to define. Still others, such as potash, phosphate, and sodium, are leasable. Case studies on limestone, pumice, and decorative stone are presented below to illustrate how the common versus uncommon standards have been applied by the courts. In most cases, mineral operators feel it is advantageous to have their deposit on public lands classified as a locatable mineral. The reasons for this are several. Disposal of leasable and salable minerals on Federal lands is discretionary on the part of the Federal agency. Locatable mining activities, on the other hand, are non-discretionary, require no Federal royalties be paid, and give claimants the opportunity to patent the Federal mineral and surface estates. Several recent attempts to reform the 1872 Mining Law have been narrowly defeated, but some form of reform legislation may eventually pass, into law in the near future.

The results of the initial sampling indicated that arsenic concentrations within the uncontained tailings ponds exceeded established human health risk-based limits. A transient, white, crystalline precipitate coating the tailings ponds was noted during site visits in June and August 1994, but not at other times. Due to the abundance of arsenopyrite in the tailings, it was assumed that the precipitate may be toxic, arsenic-bearing compounds. Subsequent removal of the moose corpse by a bear prevented performing an autopsy to conclusively link the death of the moose to the arsenic. Results of subsequent arsenic speciation studies indicated that arsenic is present as a component of relatively insoluble arsenopyrite, and within soluble arsenic-bearing oxides. This led to uncertainty regarding whether the arsenic in the tailings is currently of a form which could have caused the death of the moose and what conditions, if any, may have resulted in an increase in toxicity. An Engineering Evaluation/Cost Analysis (EE/CA) studied six alternatives for removal actions at the Beauty Bay Mine site. These included fencing, containment, off-site disposal, and on-site treatment. Based on the comparative analysis of the alternatives and comments on the draft of this EE/CA by the National Park Service (NPS) and the Environmental Protection Agency (EPA), stabilizing the tailings with a concrete mixture is the recommended removal action alternative.

Concurrently, increasingly strict environmental requirements and changing demographics require the industry to consider not only the immediate impact of their operations but the effect on the surrounding ecosystem and viewsheds as well. Much of the environmental impact from oil and gas operations results from the surface disturbance associated with geophysical acquisition, exploratory drilling, and production facilities. This paper, adapted from a Colorado School of Mines Guest Lecture, will present examples that demonstrate methods the industry has devised to reduce surface impacts in sensitive environments or urban areas. These include vehicle modifications, remote acquisition of seismic data, containerized mud systems or zero-discharge drilling, use of existing vegetation and topography to diminish viewshed degradation, and an extensive array of secondary containment techniques. Facility design incorporating reclamation considerations can effectively and economically restore abandoned well sites and production facilities to near natural appearance. Creation of new rig roads is a contentious issue on public lands. Studies have shown environmental impacts from oil and gas operations per se are not nearly as detrimental as the unrestricted access into previously roadless areas. Management methods for new development include closing or limiting access on rig roads, maximizing use of existing roads and pads, multiple wells drilled from a single pad, using non-traditional vehicles, and reclaiming roads upon completing operations.

But during that 125 year period we have seen significant changes on the American scene in our values, culture, sustainability of resources and the curricula we teach. These changes have influenced how we perceive the use of earth science for the management of the National Parks. The influence of geoscience on resource management has changed considerably over time, reflecting our changing culture and societal values. Using the NPS timeline we can demonstrate the influences of the predominate thinking of the times. In the early years, the conservationists had a substantial influence on how the park service viewed earth science. In the past few decades the NPS has become more and more under the influence of the ecosystem concept, which has geoscience firmly integrated with the life sciences and across the political boundaries on the American landscape. By putting geoscience in the context of natural resource management in the National Park System we will examine some of the questions raised for this session. A few words borrowed from President Franklin D. Roosevelt highlight the values expressed in the National Parks, "There is nothing so American as our National Parks. The scenery and wildlife are native. The fundamental idea behind the parks is native." So perhaps this American system of parks is a true reflection of American culture and values upon which we can measure the changing influence of earth science over time.

The links of geological interpretation and education with geothermal systems succeed best if Tilden's (1957) principles are kept in mind. These principles can be paraphrased as: 1) interpretation should link with the experiences of visitors; 2) interpretation involves revelation based on information; 3) interpretation is an art; 4) the aim of interpretation is provocation, not just instruction; 5) interpretation should present the whole rather than the part; and 6) children are different. Guided observation of Echinus Geyser and other geothermal features at Norris Geyser Basin and a field exercise at Pocket Basin illustrate the close parallels of Tilden's principles with constructivist learning environments. At Echinus, visitor and student questions lead to basic geologic principles of other geysers, the Yellowstone caldera and regional fault systems. At Pocket Basin, observations about the geographic distribution of mud pots and hot springs, unusual features of sedimentary rocks, and ellipsoidal hill morphology with steep inner and gentle outer slopes can be integrated. With Socratic guidance, students successfully interpret the geology of a hydrothermal explosion crater. Visitors and students, who often have many points of confusion about geology (e.g., "When will Old Faithful erupt?"), can be encouraged to observe, introduced to thinking geologically and provided a context at one thermal site that will enable them to interpret other geological features.

AN - 52576437; 1998-051450 AB - Sustainable mining is generally considered to be an oxymoron because mineral deposits are viewed as nonrenewable resources that are fixed in the crust. However, minerals are conserved and recycled by plate tectonics which continually creates and destroys ore deposits. Though it is true that rock cycles have much longer periods than biomass cycles, the crust is essentially an infinite reservoir so long as we continue to invest in mineral exploration and processing technology. Implicit in the definition of sustainable development is the recognition that human development of resources in one reservoir may subsequently degrade resources supplied by another. The depreciation of overlapping and adjacent resources is often externalized in the cost to benefit accounting and cannot be sustained if the integrated cost/benefit ratio is greater than 1. The greatest obstacle to sustainability in mining is the expanding scale of excavation required to develop leaner ores because this activity degrades connected resources. In the case of open pit, sulfide ore mining the disturbed land may produce acid rock drainage (ARD). Because ARD will self-generate over the course of tens to hundreds of years the cost of controlling this pollution and rehabilitating mined lands is large and often spread over many generations. Secondary production of minerals from partially excavated deposits where there are preexisting environmental impacts and mine infrastructure help to reduce the risk of depreciating pristine resources, provided that new mining operations "do no (additional) harm" (Margoles, 1996). In turn, a percentage of the profits derived from secondary mineral production can be used for rehabilitation of the previously mined lands. These lands contain significant, albeit low grade, metal concentrations. These concepts are being developed and tested at the Mineral Park Sustainable Mining Research Facility where an in situ copper sulfide mining field experiment was conducted. Monitoring data and computer modeling indicate that ARD is not generated after closure. This is because the ore is not disturbed and is left saturated, whereas unsaturated conditions generate acidic drainage. The short term risk of groundwater contamination is mitigated by utilizing an exempt mine pit to capture any leach solutions that are not intercepted by the wellfield. Using green accounting techniques and transfer models it can be communicated that this mining scenario is an approach to sustainability.

Westward, structurally higher rocks are mylonitic in the down-to-the-west Middle Mountain shear zone. A 12 km-long zone along the west margin of the pluton contains abundant stoped blocks of higher stratigraphic units. Recently identified stope blocks contain clues to their origin: They originated at a flexure in the roof formed by approximately 37-45 Ma extensional shear. Stope blocks typically consist of steeply-dipping, highly sheared rocks of units stratigraphically higher than the Elba Quartzite, despite the nearby roof of the pluton typically consisting of nearly horizontal, undeformed Elba Quartzite. These tilted blocks peeled from the roof, with dip steepening with distance from the roof. In stope blocks, the Elba is only slightly deformed but higher units are strongly sheared and diked by undeformed granite, indicating that an older shear zone, not presently exposed in nearby roof rocks, was preserved in the foundered blocks. We propose that the sheared rocks represent a latest Eocene shear zone identified in the same stratigraphic units in the nearby Vipont Mountain area. The top-to-the-northwest extensional shear zone exhumed crust in the future location of the Almo pluton, producing a hinge in the crust. The pluton intruded this hinge and stoped blocks of sheared rocks along it. During the early Miocene ( approximately 20-25 Ma), rocks farther west were sheared again nearly parallel to shear directions in the Eocene, an event only locally expressed in the Albion Mountains and rarely observed in the Almo pluton. Plutonism thus occurred between extensional shear events, contrary to relations in many metamorphic core complexes.

Our suite of samples consist of 128 Tertiary lavas from Nevada, Utah, and Montana. These samples were selected from a larger suite of over 600 samples. The FeO for each lava in our data base was obtained using colorimetric methods. An empirical equation (Sack et al., 1980) relating mole fraction of Fe (sub 2) O (sub 3) and FeO to absolute temperature and liquid composition at 1 bar was utilized to estimate oxygen fugacity for each lava. This enabled a comparison between the empirical equation with oxygen fugacity estimates from microprobed ilmenite and magnetite pairs. A comparison of the two methods indicates that magmatic oxygen fugacities calculated using measured whole-rock FeO/Fe (sub 2) O (sub 3) ratios are usually in agreement with magnetite-ilmenite pairs as long as the lava sample has more than 5% total Fe (sub 2) O (sub 3) . The resulting data suggest a spatial relationship between trace and major element compositions, location, and inferred magmatic oxygen fugacity. Fe (sub 2) O (sub 3) , K (sub 2) O, Na (sub 2) O and inferred magmatic oxygen fugacity all appear to increase eastward through Nevada and into Utah. Similar increases in Cu, Ni, Pb, Sr, and Ba content may be attributed to the melting or assimilation of phlogopite-rich, metasomatic veins that are present, or more abundant in the Proterozoic lithosphere east of an inferred suture zone located approximately beneath the Roberts Mountain Thrust.

Since the creation of the NPS in 1916, the park management philosophy has developed and evolved, though not without controversy over the years. The management policy of park resource managers is summarized as "when in doubt, err on the side of protection of the resource". Implementing this policy, within the context of the modern ecology movement and ecosystem management, requires NPS managers to be scientifically informed as well as politically aware. While often seen as a issue relative to the biologic resources of parks, this is equally relevant to the geosciences. Resource management decisions require consideration of complex geoscience (e.g., geology, hydrology, geochemistry), engineering and mitigation techniques, and economics. Frequently, park managers are faced with extractive mineral development that threatens the integrity of park resources. NPS administrative activities, such as facility construction and road building, have the potential to be equally disruptive. Geosciences are a key component that must be integrated into resource management planning and decision making, with critical attention to risk management, generally within a highly public and often politically sensitive context. The challenge to scientists is to maintain quality, integrity, and credibility while providing useable information to decision makers addressing real world questions and solutions. This is made more difficult when the resource manager or decision makers is not a scientist. Scientists can't assume that the correct conclusion will be drawn from an objective presentation of facts. Thus, an interpretation of the information is required, including what we know and what we don't know. The issue then becomes when does "interpretation" cross over the line to "advocacy" and how does the scientist address this concern. The scientist must keep in mind who needs the information and when and where it will be applied, as well as always being aware of how the information is being used in day to day resource management and decision making. This talk will address specific examples facing the NPS, such as mineral development, facility construction, and historic preservation.

It is not generally appreciated that a contemporaneous tectonic episode affected a large part of the central and northern parts of the Rocky Mountains of the western United States. Strata as young as the Jefferson and Darby formations of late Devonian (Frasnian) age and down to pre-Cambrian basement have been truncated beneath a regional discontinuity at the base of latest Devonian (Famennian) Englewood, Exshaw and Parting or earliest Mississippian (Kinderhookian) Lodgepole and Madison formations. The pre-Pennsylvanian rock record of the region is treated in the form of synthem stratigraphy in order to simplify nomenclature and to highlight episodes of hiatus and discontinuity in the section. In terms of synthem stratigraphy the Acadian discontinuity separates the older Piankasha from the younger Tamaroa Synthems (= Sequences) of Wheeler. Over a large part of central Wyoming the latest Devonian discontinuous basal thin sandy unit of the Tamaroa has been traditionally assigned to the Cambrian System, resulting in a misinterpretation of the geologic history of the area.

This has become the largest wetland in the delta region containing rare and endangered species, yet little is known about the environmental impact of these changes. The water quality of the salt marsh is of growing concern to the Bureau of Reclamation (BOR) which operates the Desalting Plant. Although their mandate relates to the salinity of the Colorado River above the Morales Dam, providing a stable environment down river of the Yuma Desalting plant is very important. Consequently, the BOR joined with U.S. Geological Survey scientists in 1996 to map the spectral characteristics and growth response of the Cienega de Santa Clara wetland species to best predict the environmental effects of saline level changes. The investigation is based on the hypothesis that the growth of the Cienega wetland vegetation is influenced by changes in flow and salinity of input water from the Yuma Desalting Plant. The application of satellite multitemporal imagery and spectral characterization of vegetation are used for measuring the environmental changes taking place in the Cienega de Santa Clara wetlands. Significant correlations are found to exist between spectral radiance data and recession and growth of cattail (Typa domingenis).

The poster session will walk a viewer through the software windows that are used within ALMRS showing the progression of the import GCDB process through the Build Case and Build Land Status processes. Individual data stores used in deriving each spatial component will be displayed as well as the derived spatial coverages for each of the three steps; Import GCDB, Build Case, and Build Land Status. Arc/Info's region feature classes will show how vertical integration of GCDB, Case, and Land Status can be maintained in a single Arc/Info data layer. The Import GCDB spatial coverage regions will show the following regions: Township, Section, Quarter Sections, Quarter-Quarter Sections, Government Lots, Tracts, and other special surveys. Case information and Land status regions will be derived from the Case, Land, and spatial components of the ALMRS database stored in Informix.

Thus far, five wells have been drilled in this vast province. This drilling has yielded noncommercial discoveries of gas or oil in four wells, drilled on the initially perceived most-promising prospects. With some modification, the major stratigraphic depositional systems of the North Slope persist offshore. However, indigenous and primary reservoir properties are limited to the Neocomian Breakup Sequence sandstones, rather than the Ellesmerian reservoirs of the Prudhoe Bay area found downsection. Of the known North Slope oil-source rocks, geochemistry shows that the predominantly carbonate Shublik Formation is the richest source rock of the Chukchi area. However, the Chukchi oil does not correlate well with the Prudhoe oil suite which is also derived from the Shublik. Instead, the chemistry of the Chukchi oil indicates it is derived from marine clastic rocks. Drilling in the Chukchi Sea shows that none of the potential marine clastic rocks have sufficient organic richness or kerogens to generate oil. JF - Professional Report - Alaska.

Although additional data have been gathered and new technologies have been developed there is still no consensus towards a prudent disposition of the resources. It is clear that emotional concerns currently outweigh analytical analyses as backers of development propose changing the area's name to the "Arctic Oil Reserve" whereas development adversaries refer to the area as the "Serengeti of the North." Concerns about potential conflicts between high-density caribou calving areas and development illustrate this problem. Hydrocarbon resources are not evenly distributed across the coastal plain. Two significantly large seismically prospects have the most potential for development. The Marsh Creek Anticline and Point Thomson area are also significant but have less potential. Whereas caribou calve in the 1002 area in many years, the high-density calving areas coincide with the largest seismically mapped prospects in only two of the twenty-three years when calving activities were recorded. In addition, advances in exploration and development technologies like extended reach drilling, smaller facility citing and the elimination of mudpits result in smaller footprints which mitigate against adverse affects to the environment and subsequent compromise of critical wildlife habitat. These are the criteria against which development and wildlife should be compared.

The Wyoming part of the basin contains about 500 square miles of clinker -- half in the Rochelle Hills east of Gillette and Wright; the remainder lies east of Sheridan and Buffalo, and in the Tongue and Powder River valleys. The Montana part of the basin contains about 1100 square miles of clinker. The clinker in place was produced by the natural burning of some 30 to 40 billion tons of coal. Much additional clinker has been eroded away. Zircon fission-track ages show that most of this clinker has formed within the past three million years. Within historical times most major coal-bed fires have been extinguished, but some are still burning, and new ones ignite from range fires and spontaneous combustion. As a coal bed burns into a hillside, overlying strata harden and collapse into the void where the coal used to be. The resulting clinker is more resistant to erosion than the unbaked rocks or sediments because it is harder, and being highly fractured, allows water to infiltrate rapidly, thereby reducing runoff. As a result, clinker caps ridges and escarpments and controls the topography of much of the basin. The overall reddish color of clinker is due to the oxidation of iron; darker "chimneys" of harder rock represent areas of intense heating. Up close, the color and texture of clinker vary depending on the original lithology, degree of heating, degree of oxidation or reduction. Colors range from red, maroon, yellow, and pink in oxidized rocks to gray, black, and green in limited reduced areas. Textures range from the original shale or sandstone to porcellanite, paralava, and even glass. The interface between coal and clinker along the "burn line" poses four major challenges for coal mining: 1) determining the location of the coal; 2) preventing water inflow problems; 3) maintaining adequate coal quality to satisfy contracts; and 4) dealing with increased mining difficulty. Spontaneous combustion of exposed coal is common in most mines. Drilling, magnetometer surveys, and seismic studies can all be used to delineate the limit of the clinker. Prehistoric Native Americans used porcellanite for spear points and arrowheads. Today, the main use of clinker is for road surfacing in coal mines and in areas where better quality gravel is not available. It is lightweight and easily excavated but varies in hardness and breaks down easily. Clinker works well as a cement-treated road base and as chip seal on asphalt roads. Clinker is also used for landscaping, street sanding, and erosion control. Several hundred thousand cubic yards of clinker are sold in Wyoming each year by the U.S. Bureau of Land Management and the U.S. Forest Service.

These measurements, however, are usually time consuming, labor intensive, and expensive. This paper describes a water-level sensor that is inexpensive and easy to construct. The sensor is placed below the expected low water level in a shallow well and, when connected to a data-logger, uses a pressure transducer to detect groundwater or surface water elevations. Details of pressure transducer theory, sensor construction, calibration, and examples of field installations are presented. Although the transducers must be individually calibrated, the sensors have a linear response to changing water levels (r super(2) approximately .999). Measurement errors resulting from temperature fluctuations are shown to be about 4 cm over a 35 degree C temperature range, but are minimal when the sensors are installed in groundwater wells where temperatures are less variable. Greater accuracy may be obtained by incorporating water temperature data into the initial calibration (0.14 cm error over a 35 degree C temperature range). Examples of the utility of these sensors in studies of groundwater/surface water interactions and the effects of water level fluctuations on tree growth are provided.

Black Terns in Canada decreased at an average annual rate of 3.5% during this interval, while the United States population showed no significant trends. These long-term declines largely reflect trends prior to 1980, when the continental, Canadian, and United States populations decreased at average annual rates of 7.5%, 5.6%, and 11.9%, respectively. Most population trends were reversed during the 1990s, causing trend estimates over the 1980-1996 interval to become more positive. Associations between patterns of change in Black Terns, Mallards (Anas platyrhynchos), and numbers of ponds in the northern Great Plains suggest some relationships exist between habitat availability and the population trajectories.

We compared captive- and parent-reared killdeer, and parent-reared piping plovers and determined that growth and behavior were similar. After surrogate trials determined that captive-rearing was feasible, we used the same methods to raise piping plover chicks from salvaged eggs. For captive-reared chick of both species, survival to fledging was higher than and behaviors similar to parent-reared chicks in the wild. Rearing techniques were fine-tuned, and ten piping plover fledglings were released to the wild.

Hawaiian seabirds were recorded flying to or from inland nesting colonies at seven sampling sites on the windward side of the island of Hawai'i. In total, 527 radar "targets" identified as petrel or shearwater-type on the basis of speed, flight behavior, and radar signal strength were observed during eight nights of sampling. Mean movement rates (targets per minute) for seabird targets were 0.1, 0.1, 0.3, 3.8, 0.9, and 2.2 for surveys at Kahakai, Kapoho, Mauna Loa, Pali Uli, Pu'ulena Crater, and Waipi'o Valley, respectively. Two percent of the petrel and shearwater-type targets detected on radar were confirmed visually or aurally. Flight paths for seabird targets showed strong directionality at six sampling sites. Mean flight speed for seabird targets (n = 524) was 61 km/hr for all survey areas. Peak detection times for seabirds were from 0430 to 0530 hours for birds flying to sea and 2000 to 2150 hours for birds returning to colonies. Most inland, low-elevation sampling sites could not be surveyed reliably for seabirds during the evening activity periods because of radar interference from insects and rapidly flying bats. At those inland sites predawn sampling was the best time for using radar to detect Hawaiian seabirds moving seaward. Hawaiian hoary bats were recorded at eight sampling sites. Eighty-six to 89 radar targets that exhibited erratic flight behavior were identified as "batlike" targets; 17% of these batlike radar targets were confirmed visually. Band-rumped storm-petrels were not identified during our surveys. JF - Pacific Science AU - Reynolds, M H AU - Cooper, BA AU - Day, R H AD - USGS/BRD Pacific Islands Ecosystem Res.

Detailed sampling along a 6-mile reach showed strong spatial decoupling between uranium and nitrate. Dissolved uranium decreased markedly in the upstream half and showed a large positive correlation with dissolved sodium, magnesium, sulphate, boron and lithium which were derived from leaching of the surrounding shaley soils. Most nitrate contamination occurred in the lower part of the stream which received sub-surface irrigation drainage. Isotopic measurements confirmed that dissolved nitrate was derived from fertilizer and soil organic nitrogen but showed little evidence of fertilizer-derived uranium in which the uranium-234:uranium-238 activity ratio was 1.0. A soil column experiment demonstrated that soil-bound uranium was readily leachable whereas uranium added with liquid fertilizer was largely retained. The mobility of fertilizer-derived uranium was reduced by formation of a calcium-phosphorus-uranium precipitate due to the reaction of fertilizer solution with gypsum-derived soluble calcium.

Historical information about pre- and post-dam waterbird distribution showed that flow regulation increased winter and breeding waterbird populations in both lower Glen canyon and upper Grand canyon. The post-dam populations are dominated by 13 diving and 12 dabbling Anseriformes. Most waders and shorebirds are migrants or summer vagrants. Total area adjusted rate of encounter was greatest in the productive clear water and variably turbid segments upstream of the Little Colorado river, decreasing downstream on the usually turbid lower Grand canyon segment. Seasonal waterfowl population densities were more closely related to turbidity than to reach width. There was a non-linear circuitous shift in the waterbird assemblage against distance downstream from the dam. There are 92 references.

The contingent valuation method was used with willingness to pay, modelled according to the work of Freeman. Strategic, hypothetical, procedural, starting-point and informational biases needed to be addressed. Estimated willingness to pay was 4.43-17.29 U.S. dollars per household.month. In terms of present water charges, the increases were 9-26 per cent. The highest values occurred where water was hauled. The high quality of the results probably came from experience of the problems and a reasonably accurate knowledge of water costs. Income, the cost of obtaining water and measures of use explained most of the variation in willingness to pay for improvements. The analyses would be useful in helping officials allocate limited funds. JF - Water Resources Research AU - Piper, S AU - Martin, W E AD - U.S. Bureau of Reclamation, Denver, Colo.

A solution was found by the removal of free chlorine with ammonia and the resulting chloramine was found to have adequate disinfecting properties for microbiological control. Tests showed that 1 mg free chlorine per litre in the feedwater caused a rapid increase in the salt transport coefficient in the first element of a 2 element membrane series. It was then discovered that stainless steel pressure control valves contained some carbon steel parts. After replacement of the valves by ones that were all stainless steel, membrane degradation ceased. A further series of tests revealed that an unstable iron compound was formed by the reaction of chlorine with the carbon steel, which had a catalytic effect on the degradation of the membranes in the presence of chlorine.

Correlation and anomaly pattern analyses are used to identify relationships between winter mean atmospheric circulation and temporal and spatial variability in annual streamflow. Results indicate that variability in winter mean 700-Hpa height anomalies accounts for a statistically significant portion of the temporal variability in annual streamflow in the western United States. In general, above-average annual streamflow is associated with negative winter mean 700-Hpa height anomalies over the eastern North Pacific Ocean and/or the western United States. The anomalies produce an anomalous flow of moist air from the eastern North Pacific Ocean into the western United States that increases winter precipitation and snowpack accumulations, and subsequently streamflow. Winter mean 700-hPa height anomalies also account for statistically significant differences in spatial distributions of annual streamflow. As part of this study, winter mean atmospheric circulation patterns for the 40 years analysed were classified into five winter mean 700-hPa height anomaly patterns. These patterns are related to statistically significant and physically meaningful differences in spatial distributions of annual streamflow.

Sediment cores spanned the period from 1969, when the reservoir was impounded, to 1992, when the cores were collected. Chemical concentrations in reservoir sediment samples were compared to concentrations for 14 streambed sediment samples from the Trinity River Basin and to reported concentrations for soils in the eastern Untied States and shale. These comparisons indicate that sediments deposited in Lake Livingston are representative of the environmental setting of Lake Livingston within the Trinity River Basin. Vertical changes in concentrations within sediment cores indicate temporal trends of decreasing concentrations of lead, sodium, barium, and total DDT (DDT plus its metabolites DDD and DDE) in the Trinity River. Possible increasing temporal trends are indicated for chlordane and dieldrin.

Based on data from sea urchin fertilization and embryological development assays, toxicity was observed near four of the five platforms sampled; the majority of the toxic samples were collected within 150 m of a platform. There was excellent agreement among the results of porewater tests with three different species (sea urchin embryological development, polychaete reproduction, and copepod nauplii survival). The sediment concentrations of several metals were well in excess of sediment quality assessment guidelines at a number of stations, and good agreement was observed between predicted and observed toxicity. Porewater metal concentrations compared with EC sub(50), LOEC, and NOEC values generated for water-only exposures indicated that the porewater concentrations for several metals were high enough to account for the observed toxicity. Results of these studies utilizing highly sensitive toxicity tests suggest that the contaminant-induced impacts from offshore platforms are limited to a localized area in the immediate vicinity of the platforms.

Early workers interpreted the feature to be a Quaternary fault scarp, but recent studies indicate that the future is a fluvial scarp marking the former channel margin of the Amargosa River. Detailed topographic scarp profiles indicate that the Beatty scarp is nearly 30 m in height and has maximum scarp-slope angles of 35 degrees . Because the age of the scarp is constrained at about 9000 to 13,000 yr, the Beatty scarp provides an important reference datum for scarp degradation studies and morphologic analyses in southern Nevada.

While studies of hard-rock mining have emphasized the impact of technological innovations on mining practices, explored here is the importance of the increasing demand for minerals & the decreasing availability of high-grade ore. Mass mining techniques became necessary to extract greater amounts of usable ore, increasing production & productivity. Historical examples of new techniques of ore mining, transportation, & milling illustrate the growing reliance on workers with specialized technical training, rather than the all-around skilled miners of the past. Changing roles of miners & fluctuating wage schedules are reviewed as early sources of tension between management & organized mining labor. 2 Figures. S.

The site consists of contaminated soils and groundwater in an area of approximately 187000 square yards (156350 m (super 2) ). The step-wise, integrated method incorporated standard geologic analysis techniques and statistical techniques within a GIS environment to create the primary and interpreted data bases that were used to formulate the conceptual model of the site, and to characterize site parameters. Statistical methods were incorporated into the characterization of site properties to improve upon the discretization and distribution of site parameters. ARC/INFO was used as a tool: (1) to manage and integrate diverse data types during the development of the primary and interpreted data bases; (2) to analyze primary and interpreted data bases during surface and subsurface parameter characterization; (3) for interpretation and parameter characterization during hydrogeologic framework and hydrologic system development (incorporating contouring, attribution tables and statistical analysis); and (4) for numerical model design and parameter discretization.

Basal cover was estimated using major and minor diameter measurements of the plant mat to either the nearest mm or half-cm. Basal area was calculated using the formula for an ellipse. Area derived from this ellipse-diameter method was overestimated by a factor of 1.24. Plant area was obtained more accurately by tracing the perimeter of the plant mat on transparent drafting film or mylar; area was derived either by weighing the mylar and converting weight to area or by digitizing the perimeter tracing. Perimeter tracings yield accurate basal cover; provide a permanent, archival product for year-to-year comparisons; and allow study of adjacent or overlying cover by other plant species.

AN - 78021105; 8633881 AB - The ability of microorganisms to degrade trace levels of the hydrochlorofluorocarbons HCFC-21 and HCFC-123 was investigated. Methanotroph-linked oxidation of HCFC-21 was observed in aerobic soils, and anaerobic degradation of HCFC-21 occurred in freshwater and salt marsh sediments. Microbial degradation of HCFC-123 was observed in anoxic freshwater and salt marsh sediments, and the recovery of 1,1,1-trifluoro-2-chloroethane indicated the involvement of reductive dechlorination. No degradation of HCFC-123 was observed in aerobic soils. In some experiments, HCFCs were degraded at low (parts per billion) concentrations, raising the possibility that bacteria in nature remove HCFCs from the atmosphere.

The head of this drainage is located near the northeastern boundary of Yellowstone National Park; furthermore, Soda Butte Creek is a major tributary of the Lamar River-which in turn is a major tributary of the Yellowstone River. The National Park Service is concerned with potential development along the Park's boundary which may adversely affect both surficial and groundwater recharge into the Park. Seismic refraction surveys and Schlumberger resistivity soundings have been used to define the area's valley fill composition and thickness. The techniques were also used to determine the valley's saturated thickness. By obtaining these parameters through geophysical means, important insights pertaining to the area's hydrogeology can be developed. Since no previous hydrogeologic studies (i.e., pump tests) have been performed in this environmentally sensitive location-due, in part, to the costs and impacts associated with drilling water wells-the use of cost effective, low-impact geophysical methods is a viable means of obtaining subsurface information. The application of both seismic refraction surveys and Schlumberger resistivity soundings was done in an attempt to verify the results of each technique. By accomplishing this feat, the problem of "nonuniqueness" associated with each method can be significantly reduced.

Geological heritage sites may have scientific, historic, and aesthetic significance. Scientifically significant sites consist of geological features, rock or mineral types, paleontological resources, and landscapes that represent the best example of their kind or are so uncommon that they have great significance for science education and scientific research. Historically significant sites are places where cultural activities or events occurred because of some geological feature or landscape. Categories of historically significant sites include: (1) geological sites significant to the history of geology; (2) sacred geography of Native Americans; (3) old mining districts; and (4) geological features associated with western exploration and settlement. Aesthetically significant sites include landscapes that are visually appealing because of a particular geological setting. Many geological heritage sites have been lost or degraded by human action. Common causes for the degradation of geological sites include extraction under the mining law, flooding, vandalism, tourism, criminal theft, air pollution, and commercialization.

Linear regression of the decreasing flux allowed prediction of Kupaianaha'a shut-off to within a few days. Neither eruption T nor magma composition showed any changes before activity ceased. The decline in flux led to gradual degradation of the tube system. After two months of robust construction at the ocean entries, the process of building new land at the shoreline slowed and finally ceased. Tube degradation began at the far end of the system and migrated upslope, with breakouts occurring at progressively shorter distances from the vent. The decline in Kupaianaha's output seems to have begun early in 1991. The linear decrease in magma production indicates that the vent shut off because of linearly declining magma P in the reservoir. Heightened activity within Pu'u 'O'o, the resumption of upper east rift zone seismic swarms, the resumption of summit inflation in August 1991, and the uprift episode 40 eruption in November 1991 are perhaps direct results of the shut-down process.

This program provided the basis for detailed studies of the Beatty scarp, Bare Mountain (BM) fault, and Death Valley (DV)-Furnace Creek (FC) fault system. The Beatty scarp is a fluvial scarp whose morphology and associated age control provide an important morphologic datum for assessment of fault scarps in the region.Late Quaternary slip rates developed from detailed studies indicate that the BM and DV-FC faults represent late Quaternary faults with distinctly different levels of activity. The 20-km-long BM fault is 15 km west of Yucca Mountain. Geologic mapping, scarp profiling, and results from three trenches indicate that the recurrence interval is 100,000 yrs or more and single events are characterized by 0.8-1.5 m of vertical slip. The late Quaternary slip rate for the BM fault appears very low, probably less than 0.01 mm/yr. This rate may be typical for late Quaternary faults in the southern Great Basin. The DV and FC faults are the longest and most active faults within 50 km of Yucca Mountain. Estimated single event displacement for the 45-km-long, normal-slip, DV fault is 2.6-3.5 m with an estimated return period of 500-1300 yrs. The estimated late Holocene slip rate for the DV fault is 3-5 mm/yr. The FC fault is nearly 100 km long and displays evidence for single-event, right-lateral offsets of 2.5-3.5 m. The return period for surface-rupturing events is estimated to be 600-800 yrs. Based on offset stream courses and alluvial-fan deposits, the estimated lateral slip rate for the FC fault is 5-12 mm/yr, one of the highest slip rates for late Quaternary faults in the western U.S. JF - Abstracts with Programs - Geological Society of America AU - Anderson, L W AU - Klinger, R E AU - Piety, L A AU - Anonymous Y1 - 1996 PY - 1996 DA - 1996 SP - 194 PB - Geological Society of America (GSA), Boulder, CO VL - 28 IS - 7 SN - 0016-7592, 0016-7592 KW - United States KW - paleoseismicity KW - Basin and Range Province KW - right-lateral faults KW - lateral faults KW - slip rates KW - displacements KW - Cenozoic KW - neotectonics KW - Beatty Scarp KW - Western U.S. KW - normal faults KW - tectonics KW - Bare Mountain Fault KW - Yucca Mountain KW - seismotectonics KW - Nevada KW - faults KW - North America KW - Quaternary KW - Great Basin KW - reactivation KW - Nye County Nevada KW - rupture KW - Death Valley-Furnace Creek fault system KW - fault scarps KW - 16:Structural geology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/52711162?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=Bare+Mountain+and+Death+Valley-Furnace+Creek+faults%3B+distinctly+different+Quaternary+faults+near+Yucca+Mountain&rft.au=Anderson%2C+L+W%3BKlinger%2C+R+E%3BPiety%2C+L+A%3BAnonymous&rft.aulast=Anderson&rft.aufirst=L&rft.date=1996-01-01&rft.volume=28&rft.issue=7&rft.spage=194&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, 28th annual meeting N1 - Copyright - GeoRef, Copyright 2012, American Geosciences Institute.

Secondary minerals such as jarosite, goethite, and hematite formed by sulfide oxidation can be mapped using AVIRIS (Airborne Visible/Infrared Imaging Spectrometer) data. This NASA/JPL instrument collects 7000 radiance measurements per second in 224 spectral channels from 0.4-2.5 microns for 17mX17m pixels from an ER-2 aircraft at 20km altitude. AVIRIS data acquired in July, 1995 were corrected to surface reflectance and then mapped for mineral identity using the USGS Tricorder algorithm. Mineral maps show tailings piles having bull's eye patterns composed of a central jarosite zone surrounded by a jarosite-goethite zone, in turn surrounded by goethite or hematite zones. Since jarosite is one of the first weathering product of pyrite, areas at the center of the bull's eyes have a high acid generating capacity and are surface sources for acid water and heavy metals. These mineral maps have cut costs ($500,000) and accelerated (by 1 year) the cleanup by pin-pointing the worst acid generating areas.

This paper gives an overview of GIS methods for morphologic analysis of the vertical zonation of hillslopes, derivation of watershed morphometric characteristics, potential methods for delineation of homogeneous geomorphic units to aid ecosystem analysis, and GIS interfaces to empirical sheet and rill, runoff, and sediment yield models. The author describes new methods for analysis of vertical zonation of landscapes by separating the terrain surface into crests of ridges, upper convex slopes, lower concave slopes, troughs (drainages), flats, and enclosed basins (depressions). He then discusses their potential significance for evaluating the influence of terrain morphology on spatial distribution of soils and vegetation, and better understanding of form-process relationships in the context of hillslope processes within watersheds. Also described are GIS methods recently developed at the USGS that permit processing of vast quantities of digital elevation data to determine values for watershed morphometric parameters. These indices allow for general evaluation of hydrologic processes within basins based on their morphology and suggest potential methodologies for automatic delineation of homogeneous geomorphic units with similar hydrologic properties for ecosystem analysis of large areas. Finally, the morphologic analysis methods can be utilized to enhance GIS interfaces to empirical soil erosion, runoff, and sediment yield models that permit evaluation of sediment detachment and transport scenarios under various land management practice alternatives.

The idea of nature as a teacher and the great outdoors as the classroom is at the root of our species experience. The National Park System offers numerous and diverse opportunities for hands-on geologic education. More than 140 out of the 360 existing parks in the System were established fully or in part to preserve outstanding geologic features and processes. Additionally, the National Parks have an annual visitation of 270 million people, equivalent to the population of the United States.As part of its stewardship role the National Park Service has a significant interest in using the geologic splendor to which it has been entrusted for educational purposes. A major goal of the newly established Geologic Resources Division of the National Park Service is to facilitate the use of these open air classrooms through partnerships with the geologic and teaching communities. This classroom will be a place where the scientist, teacher, and interpreter will work together and creatively use the natural setting of a national park to touch the inquisitive minds of park visitors. The National Park Service would like to enlist those of you participating in this session to share your ideas on how best to proceed.

The fault is marked by a linear, nearly continuous surface trace that extends from south of Beatty Junction northwest for a distance of almost 100 km with very few steps or jogs. The only deposits along this length of the fault that are not faulted are interpreted to be less than several hundred years old. Age control for the alluvial deposits was established by several late Quaternary tephras and relative age criteria such as surface morphology and desert pavement, rock varnish, and soil development. Near Ubehebe Crater, sediment along the valley axis has been folded and uplifted into a north-plunging anticlinal ridge that is west of and generally parallel to the fault. Late Pleistocene geomorphic surfaces cut on the limbs of the fold have also been gently folded and uplifted. Subsequent stream erosion has cut across and along the axis of the fold exposing a continuous section of alluvial-fan deposits shed from the east off the Grapevine Mountains. At the base of this section is a bouldery basaltic gravel that overlies a 20-meter-thick rhyolitic tephra identified geochemically as the Bishop Ash (760 ka). Presently, the only alluvial fans adjacent to the fault along the Grapevine Mountains that contain basaltic gravel are located near Grapevine Springs. This indicates that the basaltic gravel in the axis of the anticline has been right-laterally offset about 6-8 km, yielding an average Quaternary lateral slip rate along the fault of about 8-10 mm/yr. This is in close agreement with our previous estimate of the late Pleistocene slip rate on the fault near Red Wall Canyon of 5-12 mm/yr (Klinger and Piety, 1994, GSA Abstracts w/Programs, v. 26, no. 7, p. 189).

One hundred and forty-three park units, those containing significant geologic resources, were contacted and 106 parks completed a survey questionaire. Most parks [88 (86%)] identified geology as a theme of interpretation, and almost all parks surveyed [98 (96%)] actively interpret geologic resources. However, the majority of the parks felt that their geology interpretive programs were only "adequate" or "needed improvement". The chief obstacles to effective interpretation of geologic resources include lack of funding, lack of geologic background among interpretive staff, and lack of geoscientists on park staffs. Parks indicated that geoscientists and the Geologic Resources Division could support interpretation by providing assistance in obtaining funds, assisting in training development, developing scientific summaries for interpretive staffs, assisting with geology programs and publications, and developing partnerships. Partnerships with the USGS, state geological surveys, professional societies, academia, and/or individual scientist and educators will be used to support and improve the interpretation of geologic resources in the National Park System.

These studies were done to determine whether irrigation drainage was causing problems related to human health, water quality, and fish and wildlife resources. Results of a study in 1991-93 of irrigation drainage associated with the Uncompahgre Project area, located in the lower Gunnison River Basin, and of the Grand Valley, located along the Colorado River, are described in this report. The focus of the report is on the sources, distribution, movement, and fate of selenium in the hydrologic and biological systems and the effects on biota. Generally, other trace- constituent concentrations in water and biota were not elevated or were not at levels of concern. Soils in the Uncompahgre Project area that primarily were derived from Mancos Shale contained the highest concentrations of total and watrer-extractable selenium. Only 5 of 128\x11alfalfa samples had selenium concentrations that exceeded a recommended dietary limit for livestock. Selenium data for soil and alfalfa indicate that irrigation might be mobilizing and redistributing selenium in the Uncompahgre Project area. Distribution of dissolved selenium in ground water is affected by the aqueous geochemical environment of the shallow ground- water system. Selenium concentrations were as high as 1,300\x11micrograms per liter in water from shallow wells. The highest concentrations of dissolved selenium were in water from wells completed in alluvium overlying the Mancos Shale of Cretaceous age; selenium concentrations were lower in water from wells completed in Mancos Shale residuum. Selenium in the study area could be mobilized by oxidation of reduced selenium, desorption from aquifer sediments, ion exchange, and dissolution. Infiltration of irrigation water and, perhaps nitrate, provide oxidizing conditions for mobilization of selenium from alluvium and shale residuum and for transport to streams and irrigation drains that are tributary to the Gunnison, Uncompahgre, and Colorado Rivers. Selenium concentrations in about 64\x11percent of water samples collected from the lower Gunnison River and about 50 percent of samples from the Colorado River near the Colorado-Utah State line exceeded the U.S.\x11Environmental Protection Agency criterion of 5\x11micrograms per liter for protection of aquatic life. Almost all selenium concentrations in samples collected during the nonirrigation season from Mancos Shale areas exceeded the aquatic-life criterion. The maximum selenium concentrations in surface-water samples were 600\x11micrograms per liter in the Uncompahgre Project area and 380\x11micrograms per liter in the Grand Valley. Irrigation drainage from the Uncompahgre Project and the Grand Valley might account for as much as 75 percent of the selenium load in the Colorado River near the Colorado-Utah State line. The primary source areas of selenium were the eastern side of the Uncompahgre Project and the western one-half of the Grand Valley, where there is extensive irrigation on soils derived from Mancos Shale. The largest mean selenium loads from tributary drainages were 14.0 pounds per day from Loutsenhizer Arroyo in the Uncompahgre Project and 12.8 pounds per day from Reed Wash in the Grand Valley. Positive correlations between selenium loads and dissolved-solids loads could indicate that salinity-control projects designed to decrease dissolved-solids loads also could decrease selenium loads from the irrigated areas. Selenium concentrations in irrigation drainage in the Grand Valley were much higher than concentrations predicted by simple evaporative concentration of irrigation source water. Selenium probably is removed from pond water by chemical and biological processes and incorporated into bottom sediment. The maximum selenium concentration in bottom sediment was 47 micrograms per gram from a pond on the eastern side of the Uncompahgre Project. Selenium concentrations in some aquatic plants and aquatic invertebrates exceeded a dietary guideline of 3 micrograms per gram dry weight for protection of fish and wildlife resources. More than 75 percent of whole-body fish samples collected from rivers and tributaries throughout the study area had selenium concentrations that exceeded the 1984 National Contaminant Biomonitoring Program 85th- percentile concentration of 0.73 microgram per gram wet weight. Whole-body fish samples from the Gunnison River had significantly higher geometric mean selenium concentrations than fish samples from the Uncompahgre and Colorado Rivers. Based on a risk assessment using selenium data for five Grand Valley streams, the selenate form of selenium could be a moderate risk to the swim-up life stage (less than 99 days old) of the endangered Colorado squawfish and to three tested life stages of the endangered razorback sucker. Zinc concentrations in Adobe Creek, Leach Creek, and Indian Wash were in the high-risk category for the swim-up life stage of Colorado squawfish. Selenium concentrations in food items of migratory birds collected at wetlands in the Uncompahgre Project area exceeded the dietary guideline for protection of consumer wildlife. Fathead minnows from ponds had high selenium concentrations, and the maximum concentration was 110\x11micrograms per gram dry weight. Selenium concentrations in bird eggs and livers generally were in the range of uncertainty regarding biological risk; however, some samples from the Uncompahgre Project area had selenium concentrations in the high-risk category. Of 65\x11bird eggs incubated, only one had any visual deformity. Five recently hatched birds and two embryos that were found dead at two ponds in the Uncompahgre Project area had selenium concentrations ranging from 19 to 43 micrograms per gram dry weight, but no abnormalities or deformities were observed. Toxicity tests on irrigation-drainage water from five Grand Valley streams indicated no significant toxicity differences between control and test samples, except for the test on fathead minnows exposed to water from Leach Creek. Bioaccumulation of selenium from water to biota was significant in the study area, and the highest bioaccumulation factor was about 20,900 from water to bird livers. Selenium accumulates in fish and birds in the study area to levels that would limit human consumption if eaten on a daily basis.It is unlikely that fish and birds taken in the study area are consumed by humans on a daily basis.

The groundwater system is fed by leakage from unlined irrigation canals lying immediately above these locations on the plateau to the northwest. The main feeder canal to the system is the Fossil Gulch Canal which transports over 60.0 million m (super 3) of water during the five to six month irrigation season. Estimates suggest that as much as 10% of this volume is lost each irrigation season to leakage. Because of canal leakage, as many as four perched aquifers have been created which outcrop on the hillsides within the Monument. Immediately north and east of the most significant paleontological site (the Horse Quarry), nearly 617,000 m (super 3) of seepage occurs annually from numerous locations. In 1994, a seismic refraction study was commissioned by Idaho Power Company to help HAFO upgrade its resource protection program through the identification of additional monitoring well locations. These monitoring wells would also have the potential for serving as dewatering wells. The refraction study was successful in mapping the extent and structure of the Shoestring Road Basalt in the area of the Fossil Gulch Canal and the Horse Quarry. Results of this study suggest that the orientation of the basalt flow funnels the ground waters from the leaking canal towards the cliffs containing the fossil beds.

Historically, surfaces were mapped with conventional surveying techniques requiring life lines and high scaling equipment. This process was dangerous, expensive, and labor intensive, often compromising the accuracy of results. Reclamation's Phoenix Area Office Technical Services Division (TSD) combined ground based close range photogrammetry, aerial photogrammetry, optical surveying and computer surface modeling to compile high accuracy topographic data. This paper illustrates the integration of technologies used to model complex surfaces and archive construction modifications in a digital environment.

The age of the debris fans and alluvial terraces contributes to understanding river hydraulics and to the history of human activity along the river, which has been concentrated on these surfaces for at least two to three millennia. Poorly sorted, coarse-grained debris-flow deposits of several ages are interbedded with, overlie, or are overlapped by three terrace-forming alluviums. The alluvial deposits are of three age groups: the striped alluvium, deposited from before 770 b.c. to about a.d. 300; the alluvium of Pueblo II age deposited from about a.d. 700 to December 1900; and the alluvium of the upper mesquite terrace, deposited from about a.d. 1400 to 1880. Two elements define the geomorphology of a typical debris fan: the large, inactive surface of the fan and a smaller, entrenched, active debris-flow channel and fan that is about one-sixth the area of the inactive fan. The inactive fan is segmented into at least three surfaces with distinctive weathering characteristics. These surfaces are conformable with underlying debris-flow deposits that date from before 770 b.c. to around a.d. 660, a.d. 660 to before a.d. 1200, and from a.d. 1200 to slightly before 1890, respectively, based on late-19th-century photographs, radiocarbon and archaeologic dating of the three stratigraphically related alluviums, and radiocarbon dating of fine-grained debris-flow deposits. These debris flows aggraded the fans in at least three stages beginning about 2.8 ka, if not earlier in the late Holocene. Several main-stem floods eroded the margin of the segmented fans, reducing fan symmetry. The entrenched, active debris-flow channels contain deposits <100 yr old, which form debris fans at the mouth of the channel adjacent to the river. Early and middle Holocene debris-flow and alluvial deposits have not been recognized, as they were evidently not preserved adjacent to the river or are buried by younger deposits.

A case study of estimating total dissolved solids concentration of ground water in the local area using the ratio method yielded estimates with an average error of less than 25 percent. The results do not support the hypothesis that useful estimates of total dissolved solids concentration cannot be made from borehole geophysical logs. The case study included a comparison of estimates of total dissolved solids concentration utilizing a resistivity of the mud input versus using resistivity of the mud filtrate input. Estimates made using resistivity of mud had a correlation coefficient of 0.97 whereas estimates using resistivity of mud filtrate had a correlation coefficient of only 0.27. The results from the case study suggest that at least in some cases the resistivity of the mud (R sub(m)) may produce a better estimate of the resistivity of water (R sub(w)) in the fully flushed zone than an estimate using the resistivity of the mud filtrate R sub(mf). The ratio method can be easily used to estimate ground-water resistivity and total dissolved solids concentration of the formation water based only on data from resistivity logs. The advantage of the method is that data on porosity, cementation exponent, temperature, and volume of clay are not required. The method, which has been used by the oil industry to crudely estimate water resistivity, is based in part on the ratio of the resistivity of a fully water-saturated formation to the resistivity of the fully flushed zone adjacent to the annulus in a mud-filled borehole. The method, which is very robust, requires only an estimate of the resistivity of a fully water-saturated formation from a deep looking induction or resistivity log, an estimate of the resistivity of the fully flushed zone from a microresistivity or short normal log, and a measurement of resistivity of the mud or mud filtrate and its temperature.

Aeromonas salmonicida from covertly-infected rainbow trout (Oncorhynchus mykiss). This assay involved injection of trout with prednisolone at 20 mg/kg body weight with subsequent elevation of water temperature from 12.5 degree C to 20 degree C over a period of 4-6 h. Trout were held at the elevated water temperature until the termination of each trial. In four separate trials involving the same covertly-infected population of rainbow trout, the SIF test consistently showed the presence of A. salmonicida as early as 3 days after initiation of the assay. Mucus and gills were the more reliable sources for isolation of the bacterium than heart, liver, spleen, kidney, or intestine. The pathogen was not detected among any fish of the same covertly-infected population that were not subjected to the SIF test.

The data retrieved from the building is the first set of data from any base-isolated building that (a) was tested to acceleration levels at the free-field similar to the zero period acceleration (ZPA) level postulated in the seismic design criteria of the building and (b) exhibits levels of relative displacement excursions which puts the isolators into the nonlinear range. The variation of the fundamental frequency as a function of changing instantaneous stiffness of the isolators is identifiable. During the shaking, the isolators (a) performed well and, having attained up to 10% hysteretic damping, effectively dissipated the incoming energy of motions and (b) reduced the drift ratios of the superstructure of the building to a maximum of 10% of the allowable, which should explain the fact that there was no damage to the structure or its contents. The primary conclusion of this study is that this base-isolated building performed well during the Northridge earthquake of 17 January 1994 when only approximately 10% of the displacement capability of the isolators were utilized. Therefore, there is every reason to believe that the building will perform well during future earthquakes in the region.

No As(V) reduction to As(III) occurred in heat-sterilized or formalin-killed controls or in live sediments incubated in air. The rate of As(V) reduction in slurries was enhanced by addition of the electron donor lactate, H sub(2), or glucose, whereas the respiratory inhibitor/uncoupler dinitrophenol, rotenone, or 2-heptyl-4-hydroxyquinoline N-oxide blocked As(V) reduction. As(V) reduction was also inhibited by tungstate but not by molybdate, sulfate, or phosphate. Nitrate inhibited As(V) reduction by its action as a preferred respiratory electron acceptor rather than as a structural analog of As(V). Nitrate-respiring sediments could reduce As(V) to As(III) once all the nitrate was removed. Chloramphenicol blocked the reduction of As(V) to As(III) in nitrate-respiring sediments, suggesting that nitrate and arsenate were reduced by separate enzyme systems. Oxidation of [2- super(14)C]acetate to super(14)CO sub(2) by salt marsh and freshwater sediments was coupled to As(V). Collectively, these results show that reduction of As(V) in sediments proceeds by a dissimilatory process. Bacterial sulfate reduction was completely inhibited by As(V) as well as by As(III).

Samples were collected in 1988-1994 from a valley between the Sawatch and Mosquito mountain ranges, to examine the recovery of the macroinvertebrate community after mine drainage started. The study used taxa richness metrics, a trophic metric and abundance of an indicator organism the mayfly (Rhithrogena hageni). Multivariate cluster analysis was used to compare communities, by water chemistry and habitat. Aquatic communities affected by metals would in certain circumstances recover quickly if instream toxicant concentrations were low. There are 57 references.

The carbon-13 fraction of dissolved inorganic carbon was minus 8.8-minus 11.4 per cent in the Upper Floridan aquifer compared to less than minus 16 per cent in the overlying hydrogeologic unit which also indicated calcite dissolution. The decrease in the strontium-87:strontium-86 ratio from 0.71004 in the surficial aquifer to 0.70852 in Upper Floridan aquifer water resulted from the interaction of dilute oxygenated recharge water with aquifer materials that were less radiogenic with depth. Groundwater downgradient from the lake was enriched in the stable isotopes of water, had a less radiogenic strontium-87:strontium-86 ratio and a low strontium(II) concentration relative to upgradient water. Anoxic lakewater leakage probably influenced strontium(II) mobility and mass-balance modelling indicated that the groundwater strontium isotopic composition was controlled primarily by cation exchange.

Compiled by the US Geographical Survey (USGS), the NGNDB was begun through the recording, encoding, & imputting of geographic names & locative attributes contained in existing maps. Official state & local maps & documents, both current & historical, are being examined by the NGNDB according to the principles, policies, & procedures of the US Board of Geographical Names to obtain the 60% of known names not available in the first series of maps. Maintenance & management programs for the system are discussed. 5 References.

Two surface collapse features, each about 3-5 m (10-15 ft) in diameter, developed on an athletic field underlain by an abandoned room-and-pillar mine 20 m (60 ft) deep. In a multiphase investigation, surface seismic techniques were utilized to characterize mine level and overburden conditions, and to design an effective drilling pattern for the remediation phase. Subsequently, borehole pressure grouting techniques were used as an abatement procedure to stabilize the ground. During this phase, borehole seismic techniques were used to further characterize subsurface conditions as more than 680 stere (890 cubic yards) of grout was injected. The surface seismic study included walkaway tests followed by a series of common offset lines that traversed the athletic field. A signal enhancement seismograph, 100-Hz geophones, and a sledge hammer were used for data acquisition. The seismic data combined with information from a mine map and several borehole logs suggested that the athletic field was divided into two zones: the western portion of the field characterized by open mine voids, and the eastern portion of the field characterized by mine voids more likely to be filled with collapsed rubble. Using these results, a drilling pattern was recommended and more than 20 boreholes were drilled in preparation for the remediation phase. Borehole logs corroborated the predicted trends. All boreholes that would allow placement of grout were selected for the grouting operations and the borehole seismic study was conducted concurrently with grouting. One shot hole and three receiver holes were selected. An air gun served as an energy source and downhole receivers consisted of 40-Hz geophones arranged in a triaxial configuration. Shot-receiver crosshole traveltimes were acquired for selected depths and these were used to determine crosshole velocity distributions prior to and during injection. Preliminary analyses of the crosshole data indicated a correlation between high velocities and competent mine overburden. In contrast, velocities tended to decrease as the mine level was reached. Both the surface seismic and the crosshole seismic studies provided valuable data and additional subsurface constraints for the characterization and remediation of this abandoned coal mine site.

Baseline data were collected over a period of 4 weeks to determine which residents in each of three homogeneous neighborhoods bagged grass clippings for curbside pickup. A total of 558 houses observed to bag grass clippings during this period were included as participants in the experiment. Following baseline, the neighborhoods were randomly assigned to one of three conditions. Results indicated that participants who made a commitment to grass cycle and to talk to their neighbors had grass bags present significantly less often than either the commitment-only or control participants. This effect was present during the 4-week intervention period and also was sustained during an immediate 4-week follow-up period and a delayed 4-week follow-up period 12 months later. There also was a diffusion effect in which the neighbors of targeted participants showed significantly more grass cycling than controls, and this effect continued to increase through the 1-year follow-up measure. On the other hand, neither commitment-only participants nor their neighbors differed from controls during any period of the experiment.

These beaches are important in maintaining the historical nesting distribution of sea turtles. The higher latitude beaches of NWFL may contribute a significant number of male hatchlings to Gulf of Mexico (GOM) sea turtle populations.

The influsions were analysed for major and minor elements (by EPMA) and for 13 trace elements (by ion microprobe). The glass inclusions preserve pre-eruptive melt compositions. The results indicate that the tonsteins were derived from K-enriched metaluminous to mildly peraluminous magmas which were highly evolved, volatile-enriched, with Rb, Nb and Y abundances characteristic of continental within-plate granites. Compositions ranged from high-SiO (sub 2) rhyolite to topaz rhyolite; the tonsteins were the result of plinian eruptions.

ER - TY - JOUR T1 - Temporal Variation in Abundance of an Isolated Population of Cutthroat Trout in Western Oregon, 1981-1991 AN - 20536025; 9226495 AB - The magnitude of variation in an isolated population of wild coastal cutthroat trout Oncorhynchus clarki clarki is described for an 11-year study period during which conditions in a Cascade Mountain drainage in western Oregon were relatively stable. Dead Horse Canyon Creek watershed, which drains 1,376 ha in the upper Molalla River, experienced no storm events or disturbances of riparian habitat that caused major changes in channel configuration. Cutthroat trout populations in Dead Horse Canyon Creek varied from year to year, while habitat conditions remained constant, which thereby complicated any analyses of the independent effects of land management activities on the population. The cutthroat trout population fluctuated substantially within and among age-classes, with young of the year showing the greatest variation and age-1 fish the least. Because most of the habitat models used to predict changes in trout populations do not incorporate natural variations in populations under similar habitat conditions, measuring the impact of land management activities by short-term studies may result in erroneous conclusions. Based on Dead Horse Canyon Creek monitoring, models that obtain data by separating habitat types and that consider only older age-classes of trout may be the most accurate in predicting changes in population levels.

Atmospheric Hg is suspected as a possible non-point source contaminant. The U.S. Bureau of Reclamation, in cooperation with the NMIMT and NMBMMR, initiated a multidisciplinary study of the headwaters of the Pecos River in 1992 in order to identify and prioritize point and non-point sources of contamination so that measures can be taken to protect water supplies for municipal, irrigation, and recreational use and to protect wildlife habitat. The largest mine in the area is the Pecos mine, a massive-sulfide deposit containing Pb, Zn, Cu, Ag and Au. Waste rock generated during mining activities (1902-1904, 1927-1939, 1943-1944) was piled at the Pecos mine site and is now a source of acidic drainage that carries elevated concentrations of metals and other elements. The crushed ore from the mine was transported by aerial tramway to the Alamitos Canyon mill (El Molino site) 18 km south of the mine. This mill site is also a source of acidic drainage that carries elevated concentrations of metals. FAAS, XRF and INAA analyses confirm that elevated concentrations of Cu, Pb, Zn and Cd occur in stream sediments below both the Pecos mine and Alamitos Canyon mill sites. In addition, Zn is elevated in sediments collected at a dam above the fish hatchery. Elevated concentrations of Cs, As, Ag, Au, W, Br, Se, Sb and Fe are also found in stream sediments collected near the Pecos mine. Chemical analyses of six sediment size fractions from six sites suggests that the metals are predominantly traveling both as larger mineral or other grains and as suspended material weathered from the mine waste pile and the tailings pile. Partial dissolution techniques designed to estimate exchangeable, organic and oxide-bound forms indicate that the largest amount of Cu and Pb were in forms solubilized by aqua regia but not by the three extraction techniques. The largest amount of Zn was associated with Fe and Mn oxides. Water quality is a major concern in the upper Pecos River and many agencies collect water samples from the river, monitoring wells, and the seeps. These data indicate that drainage from the Pecos mine is not significantly affecting the composition of the surface and groundwater in the area, except in the immediate vicinity of the Pecos mine and the mill site. Collectively, these studies suggest that Cu, Pb, Zn and other metals are eroded and leached from the Pecos mine dump and the tailings piles in Alamitos Canyon. However, the total metal addition from these sources is insignificant compared to sediment input from drainages south of Pecos village. Atmospheric deposition and weathering in the upper Pecos River basin, not the Pecos mine or mill tailings, appears to account for most of the Hg found in the waters.

These results can be explained using two end-members of terrigenous clay mineral sources, and their admixtures. The first end-member, Cluster Group I, consists of the highest (average) concentration of illite (48%) and chlorite plus kaolinite (40%) and lowest of expandable minerals (12%). In contrast, the second end-member, Cluster Group IV, has the highest concentration of expandable minerals (43%) and lowest concentrations of illite (30%) and chlorite plus kaolinite (27%). The Group I assemblages come from two regions: the eastern Aleutian Trench/Forearc and the northwestern margin of the Bering Basin off Koryak Mountains, east Siberia. Clays in the former region are derived primarily from the meta-sedimentary and meta-volcanic rocks of the Chugach Mountains with infiltrations from Alaska Peninsula, and are transported from the southeastern Kodiak Shelf of the Gulf of Alaska to the trench/forearc by the Alaska Current/Alaskan Stream. Similar clays are derived from the Koryak Mountains. Group IV clays, located within the Komandorsky and Bowers Basins and Unmak Plateau, originated from the Mio-Pliocene andesites and basalts of the eastern Kamchatka Peninsula and Aleutian Islands, respectively. It is postulated that Group II clays in the southcentral Aleutian Basin and Bowers Ridge/Basin area, and Group III clays in the northern Aleutian Basin, are mixtures obtained primarily from terrigenous sources of Group I and IV. The distribution patterns and boundaries of the cluster groups reflect the dispersal pathways of clays from the primary sources and the extent of their mixing by regional and local surface currents and mesoscale gyres/eddies. Presumably, the minor infiltration of Anadyr River clays into Group III is a result of clay transport by episodic turbidity currents. Most of the clays derived from the Alaska mainland and Russia proper do not reach the Bering Basin as these clays are trapped within the Bering Sea shelf.

Concentrations of cadmium, mercury, and selenium in some water samples exceeded aquatic-life criteria. Selenium was associated with irrigaton drainage from the Dolores Project, but other trace elements may be transported into the area in the irrigation water supply. Selenium concentrations exceeded the chronic aquatic-life criterion in water samples from lower McElmo Creek and Navajo Wash, which drain the Montezuma Valley, from newly irrigated areas, and from the Mancos River. The maximum selenium con- centration in water was 88 micrograms per liter from Navajo Wash. Concentrations of herbicides in water were less than concentrations harmful to aquatic life. Selenium concentrations in four bottom-sediment samples exceeded the baseline concentrations for soils in the Western United States. The largest selenium concentrations in biota were in samples from Navajo Wash, from newly irrigated areas north of the Montezuma Valley, and from the Mancos River basin. Selenium concentrations in aquatic-invertebrate samples from the newly irrigated areas exceeded a guideline for food items consumed by fish and wildlife. Selenium concen- trations in whole-body suckers were larger in the San Juan River downstream from the Dolores Project than upstream from the project at Four Corners. Selenium concentrations in fathead minnow samples from two sites were at adverse-effect levels. Mercury concentrations in warm-water game fish in reservoirs in the study area may be of concern to human health. Some concentrations of other trace elements exceeded background concentrations, but the concentrations were not toxicologically significant or the toxicologic significance is not known.

The crater lake has high temperatures (50-90 degree C) high acidity (pH approximately 0.0), and a high dissolved-solids content (100 g/kg). The volcano has numerous freshwater springs on its flanks, but a few on the northwestern flank are highly acidic (pH = 1.6-2.5) and have high dissolved-solids concentrations (2-22 g/kg). This study analyzes the regional groundwater system at Poas and demonstrates the likelihood that the water discharging from the acidic springs in the Rio Agrio watershed originates at the acidic crater lake. Both heat and solute transport are analyzed on a regional scale through numerical simulations using the HST3D finite-difference model, which solves the coupled equations for fluid flow, heat transport, and solute transport. The code allows fluid viscosity and density to be functions of both temperature and solute concentration. The simulations use estimates for recharge to the mountain and a range of values and various distributions of permeability and porosity. Several sensitivity analyses are performed to test how the uncertainty in many of the model parameters affects the simulation results. These uncertainties yield an estimated range of travel times from the crater lake to the Rio Agrio springs of 1-30 years, which is in close agreement with the results of tritium analyses of the springs. Calculated groundwater fluxes into and out of the crater lake are both about several hundred kg/s. These fluxes must be accounted for in water budgets of the crater lake.

Acid chloride sulfate waters of the Rio Agrio drainage basin on the northwestern flank are the only waters on Poas that are affected by leakage of acid brines from the summit hydrothermal system. Acid sulfate waters found on the northwestern flank are produced by the interaction of surface and shallow groundwater with dry and wet acid deposition of SO sub(2) and H sub(2)SO sub(4) aerosols, respectively. The acid deposition is caused by a plume of acid gases that is released by a shallow magma body located beneath the active crater of Poas. No evidence for a deep reservoir of neutral pH sodium chloride brine is found at Poas. The lack of discharge of sodium chloride waters at Poas is attributed to two factors: (1) the presence of a relatively volatile-rich magma body degassing at shallow depths (<1 km) into a high level summit groundwater system; and (2) the hydrologic structure of the volcano in which high rates of recharge combine with rapid lateral flow of shallow groundwater to prevent deep-seated sodium chloride fluids from ascending to the surface. The shallow depth of the volatile-rich magma results in the degassing of large quantities of SO sub(2) and HCl. These gases are readily hydrolyzed and quickly mix with meteoric water to form a reservoir of acid chloride-sulfate brine in the summit hydrothermal system. High recharge rates and steep hydraulic gradients associated with elevated topographic features of the summit region promote lateral flow of acid brines generated in the summit hydrothermal system. However, the same high recharge rates and steep hydraulic gradients prevent lateral flow of deep-seated fluids, thereby masking the presence of any sodium chloride brines that may exist in deeper parts of the volcanic edifice. Structural, stratigraphic, and topographic features of Poas Volcano are critical in restricting flow of acid brines to the northwestern flank of the volcano. A permeable lava-lahar sequence that outcrops in the Rio Agrio drainage basin forms a hydraulic conduit between the crater lake and acid chloride sulfate springs. Spring water residence times are estimated from tritium data and indicate that flow of acid brines from the active crater to the Rio Agrio source springs is relatively rapid (3 to 17 years). Hydraulic conductivity values of the lava-lahar sequence calculated from residence time estimates range from 10 super(-5) to 10 super(-7) m/s. These values are consistent with hydraulic conductivity values determined by aquifer tests of fractured and porous lava/pyroclastic sequences at the base of the northwestern flank of the volcano.

Coprostanol is a non-ionic, non-polar, organic molecule that associates with sediments in surface waters, and concentrations of coprostanol in bed sediments provide an indication of long-term sewage loads. Because coprostanol concentrations are dependent on particle size and percent organic carbon, a ratio between coprostanol (sewage sources) and cholestanol + cholesterol (sewage and non-sewage sources) was used to remove the biases related to particle size and percent organic carbon. The dynamics of contaminant transport in the Upper Mississippi River are influenced by both hydrologic and geochemical parameters. A mass balance model incorporating environmental parameters such as river and tributary discharge, suspended sediment concentration, fraction of organic carbon, sedimentation rates, municipal discharges and coprostanol decay rates was developed that describes coprostanol concentrations and therefore, expected patterns of municipal sewage effects on the Upper Mississippi River. Comparison of the computed and the measured coprostanol concentrations provides insight into the complex hydrologic and geochemical processes of contaminant transport and the ability to link measured chemical concentrations with hydrologic characteristics of the Mississippi River.

We continue to learn that a thorough understanding of an entire watershed is necessary to make wise decisions in the management of water resources for any particular aspect of a hydrologic basin. This means that all sorts of information must be collected and stored. Information ranges from property ownership, vegetation types, hydrologic flow, water temperature, dissolved oxygen, and life forms such as algae. What do we do with all this information? And, how can we possibly connect one type information to another in a meaningful way? As questions are asked regarding management of water resources, more and more information continues to accumulate from various sources. With the advent of computers, especially powerful stand-alone PCs, tools have become available to collect, store, and manage information regarding watersheds or river basins. One such tool or system of information management is commonly referred to as a GIS, or geographic information system. This new technology developed not only as a result of the PC, but also as the result of the need to process data that is collected by various satellites.

Nightly patrols during the peak nesting season, July to October, have found the turtles returning to Buck Island to nest within the season and after multiple year intervals. In 1991/92 pilot radio and satellite telemetry tracking studies were conducted to define hawksbill turtles internesting habitat and investigate whether or not hawksbill turtles migrate between feeding and nesting areas. Many factors have contributed to the programs success over the years, however the most critical element has been the dedicated help from local and international volunteers.

It is not known if the Southeastern U.S. coast and Gulf of Mexico (GOM) represent separate or one large nesting aggregation (NMF and USFWS 1991). In either case, undeveloped beaches in the Northeastern GOM provide important habitat for maintaining the historic nesting distribution of the loggerhead sea turtle. Two such beaches are protected on separate islands of the Apalachicola Bay, FL.

BLM's goal is to have 75 percent of its riparian-wetlands functioning properly by 1997. This document supplements TR 1737-9 and provides a thought process for assessing functioning condition of lentic riparian-wetland areas. The status of some lentic riparian-wetland areas will be relatively easy to discern while the status of others will be less evident. Appendix A contains the minimum national standards that BLM field offices will use in making this assessment for lentic riparian-wetland areas. For hard-to-discern areas, Ecological Site Inventory may be the only method to determine capability and potential and assess functionality. Using either method requires an interdisciplinary team to adequately address the complexities associated with lentic riparian-wetland areas and to report their functioning condition. The lack of specific information will place many lentic riparian-wetland areas into the category of unknown. In order for BLM to make an adequate assessment of progress towards its goal, it is imperative that areas for which no data exists be evaluated and added to the data base. As information is acquired and resource values are identified, best management practices need to be set in motion. Successful management strategies have to address the entire watershed, as upland and riparian-wetland areas are interrelated and cannot be considered separately. JF - Technical Reference - U. S.

One of the primary uses of the borehole televiewer data since the tool became operational in geophysical logging has been measurement of the orientation and distribution of planar features in a drillhole. The resolution of the borehole televiewer is capable of detecting a wide range of fracture sizes and these data can provide a wealth of information pertinent to understanding the mechanical behavior of the Earth's crust at a drillsite. Fractures provide permeable pathways for fluids and affect rock properties by chemical alteration of the surrounding rock mass. Fracture geometry is therefore important to fluid flow and permeability in reservoirs and waste disposal sites and to the safety of groundwater aquifers. In situ stresses play a major role in the stability of natural and man made structures. The measurement of stress orientation and magnitude, possible through the analysis of BHTV image data, can provide information about the ambient tectonic stresses and information crucial to the design, construction and monitoring of dams, tunnels or aqueducts. Stress orientation and magnitude also has a major impact on the development of natural fractures and subsequent movement along preexisting fault surfaces. In shallow crustal wells the constraints placed on in-situ stress from the analysis of BHTV data are important to interpreting the interaction between pore pressure and hydrostatic pressure in a well and subsequent wellbore stability. Case studies from wells that exemplify the application of BHTV data analysis to geotechnical and environmental issues are presented. The first study involved in the siting and construction of a major aqueduct/tunnel in central Utah. The objectives of this study were to characterize the natural fractures within the shallow crust at the drillsite and to determine the orientation of in-situ stresses. A second study, conducted in two phases, concerned the analysis of fractures developed in a concrete dam abutment in Colorado. Detailed measurements of the aperture of fractures detected by BHTV imaging were made at a ten month interval to help establish the integrity of the dam. Finally, a study of wellbore image data recorded at county landfill in Oregon was performed to measure the orientation, aperture and depth distribution of fractures at the site.

Three models were established to calculate travel time of Carbon-14 from the potential repository to the mountain surface: a geochemical model for retardation factors, a coupled gas-flow and heat transfer model for temperature and gas flow fields, and a particle tracker for travel time calculation. The simulations used three parallel, east-west cross-sections that were taken from the Sandia National Laboratories Interactive Graphics Information System (IGIS). Assuming that the repository is filled with 30-year-old waste at an initial areal power density of 57 kw/acre, we found that repository temperatures remain above 60 degree C for more than 10,000 years. For a tuff permeability of 10 super(-7) cm super(2), Carbon-14 travel times to the surface are mostly less than 1,000 years, for particles starting at any time within the first 10,000 years. If the tuff permeability is 100 super(-8) cm super(2), however, Carbon-14 travel times to the surface range from 3,000 to 12,000 years, for particle starting within the 10,000 years.

Dissolved oxygen concentration for experimental groups was increased with column degassing by 7.8% and with oxygen injection by 8.7%. Nitrogen level was reduced 2.2% with columns receiving air and 7.4% with the oxygen injection system. There were no differences in production, mean lengths, or mean weights among fish reared in the three treatments. Hematocrit, plasma protein levels, and mean antibody microtiters to injected Salmonella H antigen were not different among fish from the three water treatments.

The prospect of petroleum development on the 1002 area of the 10 000 km super(2) pristine coastal plain of the Arctic National Wildlife Refuge (ANWR) has been a contentious national issue. The FWS assessed the habitat and its constituent wildlife species to determine potential impacts from this development. As part of the assessment effort, research was conducted on the 163 000 member porcupine caribou (Rangifer tarandus) herd, its primary predator at calving, brown bear (Ursus arctos), and the vegetation communities on the coastal plain. We found the traditional calving area within the 1002 area had significantly greater forage species availability and nutrient quality than areas peripheral to the 1002 area. Increased post-perinatal, predator-related mortality has been associated with the foothills and mountains adjacent to the 1002 area. Displacement of the calving caribou from the 1002 area would mean a lesser abundance of high quality forage for calving cows, and calves would be subjected to a potentially higher predation risk. These factors could have a negative impact on the population dynamics of the Porcupine herd. If petroleum development were authorized on the 1002 area of ANWR, the challenge for the FWS will be to assure that the dynamics of the tundra ecosystem are adequately understood and to conserve the abundance and diversity of natural wildlife populations and their habitat.

Wildlife Refuge ER - TY - CONF T1 - Composition and sources of atmospheric dusts in snow at 3200 meters in the St. Elias Range, southeastern Alaska, USA AN - 16712689; 3709154 AB - Dusts in snow from the accumulation zone in the St. Elias Range appear from their chemical compositions to have come from terranes of rocks of ferromagnesian composition. These dusts, with respect to their composition and to the moderate degree of variation that occurs through a depositional year, are similar those deposited in Greenland. The high portion of the St. Elias Range is isolated from dominance by any local dust source terranes, because of altitude and the extent of the surrounding glacierized and snow-covered region. In Greenland the altitude is typically lower, but local sources are even less likely to dominate the character of the dusts deposited into the ice record there. The similar compositions and moderate compositional variations of dusts from these two places bear on the question of whether the dusts that are transported over long distances by the atmosphere under modern and glacial-period conditions are uniform and representative of a broad regional or even hemispheric background dust. The dusts in the snow were measured by means of a suite of major, minor, and trace rock-forming metals chosen to give information about rock types, their constituent minerals, degree of degradation (weathering), and energies of atmospheric uptake from source. The variations in amounts of rock dust through the year in the St. Elias Range snowpack have no time-stratigraphic correspondence to the also-large variations in concentrations of other species that are not constituents of rock-derived dusts, such the anions chloride, sulfate, and nitrate; the highs and lows of the two types of materials are apparently completely independent. The structure revealed by the moderately fine-scale sampling of the present study ( approximately 10 increments/y) serves as a background for the interpretation of analysis of ice core samples, in which annual layers may be too compressed to permit analysis of sub-annual samples.

Practical methods to determine survival until a week or more after the fish are stocked do not exist. These factors make it difficult to manage a production facility in an efficient manner. The low and variable survival may be caused by an inadequate supply of appropriate-size zooplankton being present when 5 d old fry are stocked. Pond preparation methods developed for striped bass and palmetto bass (M. saxatilis x M. chrysops) fry emphasize heavy fertilization of the filled ponds for several weeks before the fry are stocked. This results in a zooplankton community that has succeeded to a fairly stable state where large cladocerans and copepods are dominant. These large (0.3-5 mm) zooplankton are the proper size for 6-9 mm total length striped and palmetto bass (striped bass x white bass) fry but most may be too large for 5 d old sunshine bass, which are 3-5 mm long, to ingest (Ludwig 1993).

Investigators analysed information from a sample of contaminated sites and categorized the origin of the contamination, the treatment technologies authorized where clean-up had begun, and the national cost; this was estimated at 750 billion U.S. dollars. The present annual expenditure was estimated to be no more than 10 billion U.S. dollars, and at that rate a clean-up would take at least 75 years even on the assumption that no more sites were identified. Only 3 clean-up technologies removal, containment, and pump-and-treat were available. Little attention had been directed to in-situ treatment, and only 100 million U.S. dollars was being spent on research. The value of containment, if only as a stop-gap method while curative techniques were developed, is emphasized.

Analysis of variance showed that recovery of the 5 POC common to all experiments by the point source bailer was 11 per cent and 9 per cent lower than that of the helical-rotor sampler and downhole isobaric sampler, respectively. The coefficient of variation (CV) associated with the downhole isobaric sampler results was the smallest but was not significantly lower than that associated with the helical-rotor sampler. Apparent variation in CV was attributable to the design of the downhole isobaric sampler that eliminated 2 handling steps and the consequent exposure to air, and independent experiments indicated that the precision of groundwater POC concentrations was not a function of sample collection and isolation at in-situ pressures and temperatures. The use of a bottom-emptying device rather than pouring sample water from the top of a point source bailer into 40 ml vials increased POC recovery by 8 per cent.
