TY - JOUR T1 - Climatic constraints on floristic exchange patterns in late Paleozoic interior Africa AN - 815954150; 2011-000358 AB - During Middle Permian, north Africa was located in a biogeographic transition zone between the northern summerwet Euramerican realm dominated by seed plants, such as conifers and peltasperms, and the southern-temperate Gondwanan realm, dominated by glossopterids. Transitional areas near the Tethys margin show a strongly north-to-south orientated floristic exchange pattern between the tropical flora of Euramerica and the south-temperate flora of Gondwana. These floras, particularly in modern eastern Saudi Arabia, reveal the existence of mixed assemblages well into the Late Permian. New discoveries from the Tim Mersoi Basin, north-central Niger, permit re-evaluation of a mixed flora that suggests also non-coastal and bi-directional migratory pathways existed in interior Africa, at least up to the Middle Permian. Recently discovered low diversity conifer-dominated megafloras from the Moradi Formation in Niger lack Gondwanan elements, suggesting that, just as along the Tethys margin, little movement occurred of Gondwanan elements into the tropics. Climate models predict increased desertification in this part of interior Africa during Late Permian, which would have affected migratory routes and composition of the floral assemblages. These results and interpretations are corroborated by morphological and chemical data from paleosol profiles in the Moradi Formation, which indicate arid conditions. However, the floras from the same stratigraphic levels, dominated by conifers, and including up to 25 meter long petrified stems, seem to contradict the interpretation that moisture was a limiting factor.

AN - 815954084; 2011-000362 AB - An impressive adaptive radiation of herbivorous insects occurred on a gymnosperm-dominated flora during the Late Triassic of South Africa. This event is penecontemporaneous with similar events in Australia, U.S. Southwest and Western Europe, all which exhibit parallel expansions of generalized and mostly specialized insect herbivory on plants, expressed as insect damage on a various plant organs and tissues. The Molteno Formation of the Karoo Basin in South Africa is the best documented and most diverse Late Triassic biota, consisting of 106 localities and supplying extensive evidence for insect herbivore colonization of seven distinct habitats. Within each habitat is preferential targeting of particular plant hosts, assessed both as whole plant taxa and as unaffiliated organs, resulting in specific and complex herbivory patterns involving the frequency and diversity of 79 distinctive damage types (DTs) on about 220 whole-plant species. These DT patterns show that external foliage feeders, piercer-and-suckers, leaf miners, gallers, seed predators, borers and oviposition culprits were intricately using almost all tissue types from the dominant host plants of liverworts, lycopods, horsetails, ferns, cycads, peltasperms, corystosperms, hemshawvialeans, ginkgoaleans, voltzialean conifers, bennettitaleans and gnetophytes. What explains the timing and intensity of this spectacular ecological expansion of herbivory around 228 Ma, probably lasting a few m.y., about 90 m.y. earlier than the earliest angiosperms? One possibility involves consideration of atmospheric O (sub 2) and CO (sub 2) curves during this interval. Early and Middle Triassic times experienced a dramatic decrease of O (sub 2) to 15 % of the present atmospheric level (PAL) of 21 %, increasing to 18 % PAL by earliest Late Triassic. Simultaneously, earliest Late Triassic CO (sub 2) levels were rising from a low of 2 % of PAL, elevated several-fold compared to the current level of 0.4 %. This combination of a rapidly rising O (sub 2) level promoting arthropod respiration and growth was contrasted to rising CO (sub 2) levels allowing increased herbivory of plants as nitrogen became nutritionally limiting. Both rising O (sub 2) and CO (sub 2) levels, beyond minimal thresholds, provided a "perfect storm" for an herbivore diversification event paralleling that of the angiosperms.

The uppermost 15 m of Fort Union Fm. beneath the PETM has typical latest Paleocene plants, mammals (zone Cf3), and isotopic values, although locally there are yellow and red mudstone paleosols atypical of lower Fort Union rocks. The base of the CIE (negative shift of 3-5ppm) occurs in the first laterally persistent red mudstone paleosol containing CaCO3 nodules, which also contains the characteristic Wa0 fauna and a unique flora dominated by legumes and other taxa not present in the Paleocene. The 5-8 m overlying the lowest PETM paleosol has 1-2 variegated paleosols and also produces Wa0 fossils. The approximately 20 m of section above these lowest red paleosols is characterized by large CaCO3 nodules (possibly cemented burrow-fills), poorly developed, local paleosols, and abundant cut-and-fill deposits. Wa0 mammals are abundant, as are fossil plants representing the legume-dominated PETM flora. The highest approximately 20 m of the PETM occurs in a striking sequence of thick, laterally extensive purple-red paleosols lacking CaCO3 nodules. This fauna belongs to the Wa1 zone and the flora contains a mixture of range-through taxa, those unique to the PETM, and a few Eocene indices. The changes in fauna, flora and paleosol features occur prior to the end of the CIE. Our interpretation of the PETM sequence is that floodplains became better drained with the onset of the event, or possibly shortly prior to it, indicating more seasonal precipitation as well as higher temperatures. Biotic change was rapid, occurring within 5 m of section. The middle PETM was a period of highly unstable channels, reflecting increased rates of erosion typical of more seasonal precipitation. The upper part of the PETM, marked by an absence of CaCO3, and thick, purple-red paleosols, was deposited in a wetter climate with more stable floodplains. The fauna and flora here resemble later early Eocene assemblages even though the CIE had not yet ended. Coincident changes in fauna, flora and paleosols across the PETM suggest that all three were being forced by global environmental change.

AN - 815953614; 2011-000366 AB - Africa is characterized by major rift systems that have been active throughout the Phanerozoic, providing depositional sumps as well as physiographic corridors across the eastern, southern, and central portions of the continent. Sedimentary deposits in rift basins account for a large proportion of the African terrestrial fossil record. Does fossil accumulation in these rifts provide an unbiased sample of what was happening on the continent as a whole, or do rift systems represent an environmentally and taphonmically delimited view of Phanerozoic evolution in Africa? Answering this question requires comparisons of faunas and floras from rift and non-rift settings and consideration of environmental as well as taphonomic processes relating to rift tectonics. Depositional environments in rift settings are dominated by fluvial systems and lakes along the rift axis that may extend for 1000s of km across major latitudinal climate zones. This axial continuity contrasts with topographic and climatic variability (ranging from desert to rain forest) perpendicular to the rift axis, over distances of 10's to 100's of km. Rifts thus provide macro-ecological settings that differ markedly from those of craton, foreland basin, and passive continental margins. Rapid sedimentation and permanent burial are key to preserving high quality floral and faunal records. Rift tectonics control accommodation space and sediment input, and sedimentation rates can exceed 2 m/kyr, providing high resolution records of environmental conditions and biotas for particular time intervals (e.g., 10-1000 kyr). Climate exerts a strong secondary control on fossil preservation in rift basins; warm and dry conditions and carbonate-rich environments promote vertebrate preservation, while wetter conditions are conducive to plant preservation. Volcanism has provided added sediment influx in the Cenozoic of East Africa, increasing preservation rates and resulting in the unusually rich vertebrate fossil record associated with human evolution. The ecological, depositional, and taphonomic features of African rift systems have resulted in a paleobiological record that, while likely biased relative to the continent as a whole, also represents a long-lasting and unique evolutionary theater.

The extinction marks the termination of several large-sized, distinctly ornamented lineages that dominated during the late Aptian. The two species that survived the extinction, one of which is new, are both very small and weakly calcified. These species give rise to several slowly evolving Albian lineages that show a gradual increase in shell size and ornamentation complexity. Extraordinarily good microfossil preservation at Site 1049 enables acquisition of highly reliable and detailed oxygen and carbon isotopic records spanning from about 3 m.y. below and 2 m.y. above the boundary level. Stable isotopic analyses of bulk carbonate and of single benthic and planktonic species reveal coherent trends, with abrupt negative shifts at the boundary of 2.2ppm for d (super 13) C and 1ppm for d (super 18) O. Vertical d (super 13) C and d (super 18) O gradients are quite small, and surface and bottom water temperature estimates are surprisingly low throughout the late Aptian, whereas higher vertical stable isotope gradients and surface water temperatures are associated only with the early Albian OAE 1b black shale. (super 87) Sr/ (super 86) Sr values from Site 1049 also show an abrupt shift at the Apt/Alb boundary from average values from 0.707220 in the latest Aptian to 0.707448 in the earliest Albian. The global species extinction and geochemical shifts may have been related to water mass changes associated with opening of the South Atlantic and the environmental consequences of Cretaceous tectonism (e.g., increased outgassing, carbonate chemistry change). The foraminiferal species turnover and geochemical shifts should be considered as marker events for defining the GSSP at the base of the Albian Stage.

Although overall basaltic in composition and with isotopic signatures of MORB protoliths, Guatemalan lawsonite eclogites deviate from typical MORB or even IAB average compositions and relative element enrichments, in high-field-strength-(HFSE), large-ion- lithophile-(LILE), rare-earth-(REE), and heat-producing-elements (HPE) alike. The whole-rock data are not systematic; REE patterns range from light-REE- (LREE) rich to LREE-depleted, in the range of approximately 15 to 50 X chondrite La and 6 to 30 X Lu, some with and others lacking positive Eu anomalies; K (sub 2) O ranges from 0.02 to 2 wt% and Ba from 30 to 1400 ppm. To further examine these chemical variations, we analyzed 8 lawsonite eclogite blocks from several localities, along with their Ca-rich minerals and garnet grains by ICP-MS and LA-ICP-MS. Microstructures and previous work indicate that REE and Sr compositions may reflect the contributions of up to 4 generations of lawsonite within the eclogite samples, each with different REE and Sr-abundances. Some domains of equilibration of lawsonite and garnet are clearly related to deposition during fluid-rock interactions, and others were probably fluid-mediated. However, the eclogites are not the sum of only the trace-element rich minerals lawsonite and garnet. They also typically contain rutile and/or titanite, apatite, epidote-group minerals and, in some cases, zircon. SEM imagery of domainal microstructures suggest compositions may be controlled by a variety of "trace-element-rich" minerals. Evolving fluid-rock partitioning may help to explain the chemical evolution of the rocks, most particularly during retrogression. Although the results are complex, HFSE, LILE, REE and HPE have all likely been mobile at some point during the P-T history of these lawsonite eclogites. Interactions between crystallization and consumption of lawsonite, titanite, REE-rich epidote, apatite and zircon during more than one episode of fluid-rock interaction best explain the whole-rock compositions.

Processing of the Shuttle Radar Topography Mission (SRTM) data at the available 90 m (spatial) resolution reveals details that tie together several disparate lines of evidence for large-scale, mid-Pleistocene lakes. At Bir Tarfawi, 400 km west of the Nile, fossil fish of the last interglacial occur at the same elevation as the termination of shallow surface runoff channels north of Selima Oasis in Sudan. Stepwise infilling of the present topography suggests an extensive lake at an elevation of approximately 250 m ASL that accounts for both features. This lake extended more than 300 km south to north from the Sudan border to Kharga Oasis, and covered an area of 68,000 km (super 2) . A lower lake level at approximately 190 m coincides with the elevation of the connection with the Nile through Wadi Tushka, and with the transition from topographically higher Paleolithic sites to lower Neolithic sites in the Kiseiba region. The timing of these mid- to late Pleistocene lakes coincides with the change in drainage direction of southern Egypt. From late Tertiary to mid-Pleistocene, drainage from the Eastern Desert was to the south through Wadi Qena and west across the Kiseiba-Tushka depression. In addition to the Shuttle radar-detected channels, an isolated meander bend on the south edge of the limestone plateau west of the Nile may be a relict of this drainage. The African connection and northward drainage of the Nile began in mid-Pleistocene, perhaps aided by overflow of extensive lakes in Sudan. Although precipitation was greater in the mid-Pleistocene, overflow from annual Nile flooding following establishment of northward Nile drainage seems a more likely source for the Egyptian lakes.

Several hypotheses of origin have been proposed for MFF, but most recent results tend to indicate an ignimbrite origin as the most likely process of emplacement of the deposit. On-going geologic mapping in the western portions of MFF have identified several discreet patches of mantling material south and west of the traditional margin of the deposit identified from global mapping, some of which show internal layering that is identical in both scale and morphology to layering evident within the nearby main portion of MFF. The isolated mantling deposits are located between the margin of the main MFF deposit and Gale crater (6S, 138E), where layered materials superposed on the central peak can be hypothesized to be a possible remnant of a previously much broader MFF deposit. 676 pedestal craters around the margin of MFF were used as indicators of extensive erosion of a previously more extensive MFF deposit, which suggest that the earlier volume of MFF was 1.2 to 1.9 times the present volume of MFF (which is about 2.3 million cubic km). The potential for an even larger MFF deposit in the past means that any ignimbrite source(s) must have erupted even greater amounts of material than would be required to explain the current massive deposit. Age estimates for MFF are difficult to obtain from crater densities due to the extensively eroded nature of the surface of MFF, but mass eruption rates required to emplace 1.9 times the present MFF volume in 2.9 Ga (the upper limit for its likely age) are broadly consistent with estimates of terrestrial ignimbrite eruptions. However, if MFF resulted from discreet pulses of ignimbrite emplacement, separated by periods of quiescence, then considerably larger mass eruption rates were required for the eruptive events.

At a coarse level of time-space resolution, the change is from floras dominated by wetland plants (humid-to-subhumid climates) to those dominated by plants typical of subhumid-to-semiarid climates. At a finer scale of resolution, it can be seen that these floras are intercalated, even at the outcrop scale, and that the change from one to the other appears to represent a shift in the prevailing climate regime. This vegetational change is well represented in the Markley Formation (Uppermost Pennsylvanian-Lowermost Permian) of north-central Texas. The Markley Formation consists mainly of channel sandstones and paleosols. However, it also includes shallow incised channels within which plant-bearing shales and sandstones are preserved. These fossiliferous deposits are significant due to their range of lithologic variability, which appears within recurring stratigraphic patterns as follows: Deeply-rooted basal paleosols; immediately superjacent kaolinitic-quartzitic mudstones rich in seed-bearing plants such as sphenopterids and conifers; overlying organic shales rich in "pennsylvanian"-type lycopsids and pteridosperms; overlying floodplain mudstones that contain a highly diverse flora distinct from the underlying organic shales. These floodplain mudstones are often capped by sparsely fossiliferous fluvial sandstones that contain Cordaites foliage. Because floral composition is linked to lithologic changes, samples could be grouped into six distinct categories. Each lithologic group contains a distinct floral assemblage, consisting of well-defined dominant taxa and various groupings of accessory taxa. Recurrent patterns throughout the Markley Formation indicated that semiarid-subhumid vegetation was preserved most commonly at the base of the shallow incisions, and was succeeded in time by humid climate wetland assemblages. Furthermore, temporal changes were observed in the composition of dominant taxa within particular lithologies, which gives evidence of dominance shifts/replacements in a given environment over geologic time.

One is MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) on the Mars Express orbiter and the other is SHARAD (Shallow Radar) on the Mars Reconnaissance Orbiter. SHARAD is designed to study dielectric contrasts associated with geologic layering on fine (10 m) vertical scales and to typically sub-km depths. SHARAD complements the spatially coarse but deeper sounding of the lower-frequency MARSIS. The depth of exploration of these radars is controlled by the loss properties of the material that the radar waves pass through, with the result that ice-rich material is the most fruitful target for sounding. The radars have mapped the internal structure of the layered deposits at both poles, revealing details of the layering not observable from surface exposures and showing that the layered deposits are dominated by ice. The North Polar Layered Deposits (NPLD) are draped over the Basal Unit, which exists under the main lobe of the northern polar cap. Within the NPLD, two vertical scales of reflection spacing that appear as a packet/interpacket structure are widespread, suggesting the involvement of two different periodicities of climate forcing. A packet/interpacket structure is seen distinctly only in the Promethei Lingula region of the South Polar Layered deposits (SPLD). Beneath the sloping plateau of the SPLD (centered roughly on 180 degrees E) the layering is not as distinct, and near the highest elevation of the SPLD (Australe Mensa) layering is virtually absent. Overall, the internal radar structure seems to support the three major stratigraphic divisions proposed by Milkovich and Plaut (2008) for the SPLD. An unexpected result for both the NPLD and SPLD is that the substrates beneath deflect very little in response to the ice loads. This implies that the elastic lithosphere at the poles is very thick, or the load is not in equilibrium with the viscous mantle, or that Martian heat flow has significant spatial variations.

However, recent multi-disciplinary geoarchaeological studies give support to the writings of Homer (The Odyssey) and Strabo (The Geography) that imply that the Alexandrian sector was settled well before Alexander's arrival. In this study, pollen and microscopic charcoal from sediments collected in the Eastern Harbor of Alexandria are used to document and date changes in the vegetational landscape associated with the settling of the Alexandria coastline and subsequent human land use activities. Pollen assemblages record not only the long human history of land use in this sector but also the effects of natural climate variability on the local environment. We identify three transitions in the pollen-microscopic charcoal record. The earliest transition, approximately 6000 yrs BP, during Egypt's Predynastic period, indicates a change from a wet to an increasingly drier climate. The striking change in pollen and microscopic charcoal associated with human land use occurred 3600-2900 yrs BP, a period of continued aridity with no lithologic variation at this core interval. Pollen (cereal taxa, agricultural weeds, grape) and a sharp increase in microscopic charcoal indicate that human activity became prevalent at least 700 years before Alexander the Great's arrival in this region, highlighting the transition from a largely natural climate-controlled environment to one influenced by both climate and anthropogenic activity. A third shift in pollen assemblages is dated at approximately 2300 yrs BP, at the boundary between a sand and mud unit. The transition coincides with construction by the Ptolemies of the Heptastadion, a causeway between Alexandria and Pharos Island.

Weaker returns of similar appearance and delay time occur in many other areas across the Northern Lowlands. We build confidence in a subsurface explanation for the returns by discounting surface and ionospheric sources through comparisons with synthetic radargrams generated from topography data, use of processing that suppresses side lobes, and selection of observations from a wide range of solar zenith angles (ionospheric effects vary with time and solar zenith angle). These measures support subsurface interfaces as the source of the returns, both in the "Green Valley", where the Phoenix lander resides and elsewhere in the Northern Lowlands. The detections track southward to approximately 61 degrees N on the slopes of Alba Patera and as far south as 45 degrees N in other regions, latitudes encompassing the region where ground ice is inferred to be present on the basis of neutron-spectrometer data. Other studies have suggested that ice-rich materials may occur as layers within the Vastitas Borealis Formation, lags in late Amazonian mantles, dust-rich ice emplaced atmospherically during recent obliquity excursions, and shallow ice lenses and layers emplaced by vapor diffusion. An equilibrium condition such as this last possibility may dominate, given the relatively uniform depth of the detections. We test this idea with a numerical model and find that the base of ground ice ought to be at a depth of approximately 15 to 30 m, increasing to approximately 20 to 40 m if the present geothermal heat flow is 5 mW m (super -2) K (super -1) , a low value implied by the recent finding of unexpectedly low flexure beneath Planum Boreum [Phillips et al., 2008, Science 320, 1182]. The weak signal strength suggests either lower ice content in the near surface or a gradual transition at the base from ice rich to ice poor, rather than an abrupt interface with a large dielectric contrast, since SHARAD typically obtains a strong reflection in the latter case.

However, Holocene sea-level curves compiled for these regions, based on results of modeling by others and our field observations (coring, geophysics), indicate very modest rates of sea-level rise (slr) during this past 2700 yr time-span. Sea levels were within -1.5 m msl for periods represented by archaeological levels. For example, sites (Herakleion and others) submerged on Egypt's relatively stable Nile Delta margin and Sybaris on Calabria's major delta, the Crati, are now at depths ranging from 4.0 to 8.0 m beneath msl, or much lower than can be accounted for simply by slr. Diverse controlling factors for this include compaction, faulting and failure (liquifaction, slumping) of water-saturated sediment substrates at relatively shallow depths, plus isostatic lowering and shifts of thick deltaic sequences at greater depths. These result in high average long-term subsidence rates, such as 4 to 5 mm/yr for some sites on the Nile Delta margin. Triggers for failure along these coasts include floods, storm surges, tsunamis and earthquakes. Moreover, there is evidence of marked episodic vertical shifts of land on highly active tectonic margins, such as those of the Calabrian Arc in southern Italy and Alexandria's Eastern Harbor. The approximately 100 m rise of the approximately 125,000 yr old (Tyrrhenian) shoreline marker in hills behind the Ionian coast, and lowering of land beneath Greek sites of Kaulonia and Locri-Epizefiri at about the same rates ( approximately 1.0 mm/yr) offshore are measured. Rapid subsidence of land in Calabria caused a marked displacement of the coastline in a direction seaward, rather than landward, during the late Holocene. Overall, slr has played only a minor role in the submergence of sites we have examined to date and, from this, it is possible to surmise that other Greek and older coastal sites may yet be discovered by offshore exploration.

The strait was closed in the middle Miocene, as shown by terrestrial deposits of the underlying Cucaracha Formation (central Panama Canal Basin), and was reopened by late middle to late Miocene time when sediments of the lower Gatun Formation were deposited in the northern part of the basin. The Gatun Formation is informally divided into lower, middle and upper parts, and foraminifera from all parts have primarily Caribbean associations. Overlying the Gatun Formation is the uppermost Miocene Chagres Formation, the youngest formation of the Panama Canal Basin. Foraminifera from the type Chagres Formation have primarily Pacific associations. New foraminiferal collections were made from outcrops previously mapped as either undifferentiated volcanics or Miocene lutites, silts and conglomerates. Analyses of similarity between the foraminifera and those from different facies of the Panama Canal and Bocas del Toro basins are used to identify changes in biofacies along the 180 km of Caribbean coast between the basins. Twenty-two inner-middle neritic benthic foraminiferal assemblages from the lower, middle and upper parts of the Gatun Formation, and twelve assemblages from the middle neritic Rio Indio section and outer neritic/upperbathyal type section of the Chagres Formation are compared statistically to the newly collected assemblages from the lowermost Gatun Formation (east of the Panama Canal), and the coastline between Gobea (west of the Panama Canal) and Bocas del Toro. The paleoenvironments and biogeographic associations of the foraminiferal biofacies are incorporated into reconstructions of the history of uplift and Atlantic-Pacific connections, and to infer formational boundaries.

An earlier study of the Yixian Formation in Liaoning Province in northeastern China, indicated that the presence of brachyceran flies with characteristic long, siphonate proboscides suggest co-occurrence of correspondingly deep throated angiosperms, even though evidence for coeval flowering plants was sparse, and the few known taxa lacked nectaries and floral structures consistent with fluid-feeding by long-proboscid insects. This study inferred that the Yixian Formation was of Late Jurassic (Tithonian) age and the presence of long-proboscid flies suggested the simultaneous occurrence of angiosperms about 15 m.y. earlier than the fossil record indicated. Recently, an alternative hypothesis proposes that mid-Mesozoic long-proboscid flies instead were pollinating gymnospermous fructifications that variously possessed long micropyles, extended integumental channels, catchment funnels and other tubular features requiring a long proboscis to reach pollination drops compositionally comparable to angiosperm nectar. This hypothesis is inconsistent with earlier angiosperm presence in the fossil record, and is consilient with a mid-Early Cretaceous (Barremian) age for the Yixian Formation, as varied, modern evidence now indicates. Currently, additional long-proboscid insect taxa, including three distinctive but related lineages of scorpionflies (Mecoptera), three families of brachyceran flies (Diptera), and now a separate lineage of distinctive planipennians (Neuroptera), have been discovered, suggesting that the siphonate proboscis originated at least five times when evaluated at the family level, within approximately a 15 m.y. interval during the Middle Jurassic (Bathonian-Callovian). This correspondence of insects with stereotyped mouthparts and plants of appropriate reproductive structure indicates a Eurasian gymnospermous pollination syndrome extending to 35 m.y. before the earliest fossil flowering plants (Valanginian). At the end of the Early Cretaceous, these gymnospermous associations were extinguished.

AN - 759302611; 2010-086470 AB - When probed with subsurface sounding radar, the polar layered deposits of Mars commonly show continuous reflecting horizons, consistent with the appearance in optical imagery of well-organized strata. The banded nature of the layered deposits in images has been ascribed to variations in dust content, but numerous observations suggest that weathering style and surficial deposits are more likely the controls on apparent albedo [e.g., Herkenhoff and Murray, 1990, JGR 95 14511; Fishbaugh et al., 2009, Icarus, in press]. The aim of this study is to tie the positions of radar reflectors to outcrops of layered deposits visible in high resolution images, such as HiRISE from Mars Reconnaissance Orbiter (MRO). The morphologic and topographic characteristics of the reflecting layers can then be used to constrain the mechanism that causes a radar reflection at a particular place in the stratigraphy. We examine an area of the North Polar Layered Deposits (NPLD) that was observed numerous times by the SHAllow RADar (SHARAD) on MRO, and for which an adjacent trough was imaged in stereo by HiRISE and studied in detail for stratigraphic information [Fishbaugh et al., 2009]. These datasets allow absolute 3D positioning to be obtained for reflecting horizons in the radar data and for the associated nearby outcrop. While the radar reflectors cannot be traced all the way to the sloping exposure, an extrapolation of the flat lying layers of several km does not introduce large errors in elevation position. The upper approximately 500 m of layers are well-imaged by SHARAD, consisting of individual reflecting horizons, groups of closely spaced reflectors, and regions of low return between reflectors. Preliminary results indicate that radar reflectors may be correlated with so-called "marker beds", layers with a hummocky, protruding appearance in images of sloping exposures. This suggests that the compositional and/or textural character of these layers provides both a dielectric contrast with adjacent layers, and a mechanical contrast that results in a distinctive weathering style.

If preservation potential is taxon-independent then organisms with higher birth and death rates should be over represented in the death assemblage relative to organisms with lower birth and death rates. Measured shell half-lives show significant differences between taxa, so live abundance is expected to the same as dead abundance only if a taxon's preservation potential is inversely proportional to its productivity, i.e., shorter lived organisms have lower probabilities of preservation whereas longer-lived organisms have higher probabilities of preservation. While this assertion is intuitively appealing, it has not been widely tested. Molluscan samples from the central Great Barrier Reef (Australia), are used to determine taxon-specific preservation potential and productivity. Extending on previous work, shell size, density, shape and thickness are used to predict taphonomic durability. These predicted durabilities are then compared to the observed relative durability based on acid dissolution experiments. The agreement between predicted durability and observed durability is quite high, at least amongst aragonitic taxa. For taxa sufficiently numerous to estimate recruitment and mortality rates, the relation between durability and productivity is examined.

AN - 753851337; 2010-069681 AB - Detailed geologic mapping and new geochronology and paleomagnetic data from two transects crossing most of the Panama Isthmus show constrasting structural styles for the Panama area. Such contrasting styles can be explained in terms of the oblique collision of the Panama Block with northwestern South America, and solution of ensuing deformation in an oroclinal belt that has its western termination in the Canal area. Along the Canal area we have found pervasive extensional deformation coeval with lower to middle Miocene shalllow marine to continental sedimentation and volcanic and subvolcanic activity. Transtensional deformation formed the small Canal basin at the westernmost tip of the upper portion of an ophiolitic belt that extends east to the Colombian border. Sedimentation in the Canal Basin took place in small compartments where syntectonic sedimentation and volcanoclastic input were abundant. Middle Miocene volcanic activity was restricted to the Canal area and put an end to sedimentation. East of the canal area, we have mapped a pillow-basalt, chert, diabase sequence intruded by Paleocene-Eocene arc plutonic rocks and covered by a Oligocene and younger, nearly undeformed sedimentary sequence from shallow carbonate platform to continental clastic and volcanoclastic deposits. The ophiolite sequence is thought to be Upper Cretaceous and contains a pre-Oligocene deformational fabric. Preliminary paleomagnetic data indicates that these rocks formed south of the equator and arrived to its present position by Oligocene times. These assemblages contain the record of the Paleogene/Neogene evolution of the arc at the trailing edge of the Caribbean Plate as it drifted between the Americas, collided with northwestern South America and accommodated deformation thus shutting the volcanic arc and defining an oroclinal belt.

In the past, arc volcanism occurred throughout Panama, however today active volcanoes exist only in western Panama (e.g. El Baru and La Yeguada), and produce adakitic lavas. Modern magmatism in eastern Panama is unknown. The Panama Canal bisects these two regions and recent excavations along it have allowed for detailed study of volcanic rocks. Exposed within the Panama Canal Culebra Cut is a sequence of Oligocene to Miocene volcanic rocks, which young from north (Gamboa) to south (Panama City). The oldest unit is the Oligocene Bas Obispo Fm., composed of a thick sequence of welded mafic tuffs. The next youngest unit is the more felsic >23 Ma Las Cascadas Fm., composed of dacitic tuffs and ropey andesitic lava. Both the Bas Obispo and the Las Cascadas exhibit transitional tholeiitic to calc-alkaline trends and are interpreted to be mantle-wedge derived arc magmas. Above the Las Cascadas Fm. exist two sedimentary dominated units, oldest is the marine Culebra Fm. and is overlain by the terrestrial Cucaracha Fm. Atop the Cucaracha Fm. is the Pedro Miguel Fm. The Pedro Miguel Fm. is 100m) welded mafic pyroclastic deposits, interbedded lava flows and ash beds with a defined stratigraphy that are interpreted to be fragments of a larger volcanic ediface. The final volcanic units are Late Basaltic rocks (and within Panama City, dacite plugs (Ancon Hill)) that sit on top of and intrude through the Pedro Miguel Fm. The Late Basalt and associated dacite exhibit a transitional alkaline signature, are the youngest volcanic rocks in the canal and represent the cessation of magmatic activity in the region. The end of magmatic activity within the Canal Zone is associated with significant normal and strike-slip faulting and is temporally similar to the initiation of the collision of South America with the Panama Block. Extensional faulting observed in the Canal Zone is not widespread throughout Panama. One potential explanation is during the initial collision with South America, the Panama block fractured leading to localized regions of extension, crustal thinning and alkalic magmatism.

These large, nearly flat areas strongly contrast with the rugged topography of the Cordillera Oriental and have been attributed to fluvial deposits draining the western flank of the eastern Cordillera. These fans are located immediately west of the Sumapaz highlands of the central part of the eastern Cordillera, a range with maximum elevations of up to 4,700 m above sea level, which during glacial periods had glaciers reaching as low as 3,350 m above sea level. This range drains directly to the west (Fusa fan) and north to the Bogota plateau at 2,600m above sea level, which in turn drains to the west (Anapoima and La Mesa fans). A large lake developed in the Bogota plateau from late Pliocene to Pleistocene times, draining the surrounding glacially covered peaks. Preliminary sedimentologic observations suggest high viscosity flow conditions for the Fusa fan, with very large, probably glacial blocks, floating in a massive, muddy matrix. The combined area of these three fans is now 130 km (super 2) , with the largest preserved area in the less dissected Fusa fan (105 km (super 2) ). The conditions for the development of large, glacially induced floods were all in place during the glacial periods, with large mountain glaciers, a large glacial lake and large altitudinal gradients to the west (from 2,600 m to less than 500 m above sea level). Several alternatives can be considered, including a seismogenic triggering mechanism if all three fans are shown to be simultaneous events.

Preliminary results from the Panama canopy cranes and implications for plant-insect associational diversity in the fossil record AN - 742923099; 2010-055143 AB - Insect feeding marks on leaf compression fossils have provided substantial information on the extent and intensity of past phytophagy and the responses of terrestrial food webs to past climate change and extinction events. A crucial, uninvestigated aspect of interpreting fossil damage-type (DT) diversity is its relation to actual insect diversity: are there quantitative correlations between leaf damage and insect diversity that can be applied to reconstructing the latter through time? Even though leaf-damage richness has been widely used as a proxy for insect diversity in the fossil record, more confident use of this proxy requires establishing an empirical association between damage and insect diversity within modern communities. Canopy crane systems provide direct access to the foliage and insect communities of dominant trees in forest assemblages. Two lowland tropical forests in Panama, Parque Natural Metropolitano and Parque Nacional San Lorenzo (a seasonally dry and a moist forest, respectively), were surveyed for phytophagous insects during the wet seasons of 2008 and 2009, using the canopy crane facilities of the Smithsonian Tropical Research Institute. Thirteen species of the most dominant trees, as well as lianas and palms, at each site were intensively surveyed for feeding insects. These were captured and fed fresh leaves of the plant species they consumed in order to isolate and record the specific DTs made by each insect. A total of 520 individual insects showed feeding activity, leaving one or more DTs on the leaves. Rarefaction curves for overall damage types plateaued for each site and host plant species; however, insect species richness curves did not. Although insect and damage diversity correlate to some extent, insect mouthpart design constraints seem to set a limit to the sensitivity of insect damage diversity to actual insect richness. Further analysis of this new dataset will improve understanding of the relationship among plant, insect and leaf damage diversities and provide further actualistic groundtruthing for the relationship between plant, insect, and associational diversity in the fossil record.

AN - 742919549; 2010-055136 AB - The human-mediated extinction of large herbivorous megafauna in the late Pleistocene had profound effects on terrestrial community structure and function, but may also have influenced atmospheric gas exchange. Herbivorous mammals are major producers of methane, a potent greenhouse gas with a high global warming potential; domestic livestock currently contribute approximately 20% of the annual input. Here, using allometric relationships between body mass and density, methane production and estimates of geographic range, we calculate the annual decrease in methane production resulting from the extinction of 114 species of large-bodied herbivore from the Americas approximately 13,400-11,500 ybp. Our results suggest a loss of at least approximately 9.6 Tg (upper limit, 25.5 Tg) CH4 annually, sufficient to explain a significant portion (12.5-100%) of the approximately 200 ppbv drop detected in isotopic analyses of ice-core records. We suggest humans measurably influenced global biogeochemical processes long before the development of agriculture, complex civilizations and the obvious impacts of the industrial age.

The lower boundary of this unit is defined biostratigraphically by the oldest direct evidence for presence of life on Earth. The upper boundary is the present time (life is still around on our planet). The term Geozoic is chronostratigraphically synonymous with the expression "the entire fossil record" and geochronologically synonymous with the expression "the entire documented history of life." Geozoic encompasses multiple eons (i.e., most of the Archean, the entire Proterozoic, and all of the Phanerozoic) and merits a geochronological rank of informal supereon. The time from the formation of the Earth until the oldest direct evidence of life (i.e., the Hadean and the early Archean) can be referred to as "Pregeozoic," thus dividing the Earth's history into two informal supereons. Geozoic, defined by one of the most important events in the history of our planet (i.e., the appearance of life), reflects a more fundamental subdivision than the currently accepted and widely used informal supereons that split the Earth's history into two time intervals of "non-visible" (Precambrian/Cryptozoic) and "visible" (Phanerozoic) life. The terms "Geozoic" and "Pregeozoic" are convenient because they represent an expedient way to refer to the geological processes, patterns, and records that correspond to the interval of time during which life must have existed on our planet. Because the origin of life must predate the oldest fossilized records of life, the Geozoic supereon represents the most conservative estimate of the biosphere's existence time.

Ecological dynamics are profoundly nonlinear and exhibit threshold effects, especially under extreme conditions such as those caused by human exploitation and climate change. Thus time lags occur between environmental change and biotic responses in ecological time, and the question arises how such time lags may scale up into macroevolutionary time. The isolation of the Caribbean from the Pacific by the rise of the Panamanian Isthmus resulted in profound oceanographic changes, including a dramatic decline in productivity, that are believed to have precipitated widespread extinction. However, extinction in most groups lagged 1-2 Myr behind environmental change. We explored the reasons for this time lag in terms of the mechanistic basis for changes in life histories of cupuladriid bryozoans that are abundantly well preserved throughout the Caribbean Neogene. Through surveys and experiments, we established that clonal reproduction is more lucrative than sexual reproduction in eutrophic conditions whereas sexual reproduction is favored under oligotrophic conditions. Thus, sexual reproduction should have become more prevalent than cloning when Caribbean productivity declined, as was indeed the case. Species that switched from primarily clonal to sexual reproduction survived to the Recent, and all species that originated after the rise of the Isthmus were predominantly sexual. In contrast, species that for some reason failed to reduce their rate of clonal reproduction became extinct. As for other taxa, species extinction lagged 1-2 Myr behind environmental change, but species destined to become extinct became progressively rarer and were found in fewer collections than predominantly sexual species. This pattern of gradual, drawn out extinction is consistent with predictions of metapopulation theory and the concept of extinction debt when recolonization of local populations fails to compensate for local extinctions.

These faults cut sedimentary and volcanic units indicating significant post-Miocene trans-tensional deformation. Two large left-lateral normal oblique faults are well exposed along the canal and dip 60 degrees to the southeast . The footwall in the northern fault is generally undeformed, but the southern one has some normal faults that are syn- and antithetic to the main fault. Due to the greater density of normal faults in the hanging wall, we propose that these faults become listric at depth. Rough calculations of depth to detachment were performed on a cross section along the west bank of the Panama Canal from Gamboa to just north of Puente Centenario. Using the balanced bed length method, we calculated the detachment to be shallow at about 800 meters. Such a shallow depth to detachment is inconsistent with well documented studies of listric normal faults which generally detach at the brittle-ductile transition. However, there are substantial rheological differences between the welded agglomerates of the Bas Obispo Formation and the overlying ignimbrites and volcaniclastics of the Las Cascadas Formation which may accomodate detachment. It is proposed here that extension occurred in the canal zone along a NW/SE trend with listric faulting on faults dipping to the SE. The extension is estimated to be about 10-15% through this portion of the Gaillard Cut. This extension may be explained by termination of left lateral faults in eastern Panama as proposed by Mann and Corrigan or it may be extension related to the fragmentation and translation of micro blocks of Panamanian crust during the collision between Panama and Colombia.

These sedimentary sequences record periods of intense volcanic activity that drove high fluxes of pyroclastic material (carried both fluvialy and aerially) into the shallow nearshore marine environment, followed by periods of volcanic quiescence and a marked increase in abundance and size of Gatun fauna. We use quantitative stratigraphic data from the field and from cores coupled with estimates of faunal abundances and relative size in order to reconstruct sediment transport mechanisms and flux rates of pyroclastic material into the basin as well as to constrain biological response to these high fluxes.

a new Late Permian fossil locality from KwaZulu-Natal, South Africa AN - 921716500; 2012-022968 AB - The Clouston Farm locality, assigned to the Lopingian Epoch and occurring within the Normandien Formation of the northeastern Karoo Basin, provides evidence for a community of diverse vascular plants occupying riparian woodland. The depositional environment is interpreted as an abandoned trunk channel that preserved a megaflora in slack-water phases punctuated by overbank deposits from rare flood events. Of 9772 plant specimens tabulated from an unbiased census of all fragments greater than approximately 1 cm (super 2) , there are 51 distinct organ morphotypes, including glossopterids, sphenopsids, and ferns, collectively represented as foliage, axes, fructifications, and dispersed seeds. Of the 11 most abundant morphotypes 10 are glossopterid morphotypes or variant subtypes, in addition to a sphenopsid. Glossopterid morphotype dominance also is reflected in the palynoflora. Palynological data indicate a Wuchiapingian age for the locality. A specimen of the dicynodont 'Oudenodon,' found in a nearby stratigraphically equivalent outcrop, is attributable to the Dicynodon Assemblage Zone, assigned a younger Changhsingian age. A rich record of plant-insect associations demonstrates an elevated frequency of external foliage feeding by mandibulate insects and lower incidence of oviposition by palaeodictyopteroid and odonatopteroid taxa. Evidence for piercing-and-sucking and galling is rare. The most abundant plant taxon (glossopterid Morphotype C2a) is the most intensively herbivorized, overwhelmingly by external feeding and ovipositing insects. Insect damage on this host is beyond that predicted by floristic abundance alone. This specificity, and high herbivory levels on other glossopterid taxa, demonstrates extension of the Euramerican pattern toward the preferential targeting of pteridosperms. The Clouston Farm site provides a glimpse into a late Permian ecosystem of primary producers, herbivores, and insectivores-a prelude to the crisis that engulfed life at the end of the period.

(formerly Discinispora) from China, an ichnotaxon of a punch-and-sucking insect on Noeggerathialean spores AN - 921714925; 2012-022954 AB - The generic name Discinispora Wang, Zhang, Bek et Pfefferkorn was originally created for spores with an operculum-like structure that were found in a permineralized Noeggerathialean cone. Subsequently it was observed that up to three round and smooth openings can occur in different positions on the surface of a single spore. In light of the new observations, the previous interpretation as an operculum cannot be sustained. An interpretation implicating insect punch-and-sucking activity was suggested for these round structures. This new interpretation makes it necessary to withdraw the original diagnosis and the taxon. The insect-inflicted damage now is assigned to the ichnotaxon Circulipuncturites discinisporis Labandeira, Wang, Zhang, Bek et Pfefferkorn under the rules of the ICZN, rather than those of the ICBN that typified the insect-damaged host-plant spore.

The stars were selected from the literature on the basis of their far-infrared (IR) excess (i.e., post-AGB candidates) and B spectral type (i.e., close to the ionization of the envelope). The combination of our IRAC observations with Two Micron All Sky Survey and IRAS catalog data, along with previous radio observations in the cm range (where available) allowed us to model the spectral energy distributions of our targets and find that in almost all of them at least two shells of dust at different temperatures must be present, the hot dust component ranging up to 10 (super 3) K. In several targets, grains larger than 1 mu m are needed to match the far-IR data points. In particular, in IRAS 17423-1755 grains up to 100 mu m must be introduced to match the emission in the millimeter range. We obtained IRS spectra to identify the chemistry of the envelopes and found that more than one-third of the sources in our sample have mixed chemistry, showing both mid-IR bands attributed to polycyclic aromatic hydrocarbons (PAHs) and silicate features. The analysis of the PAH features indicates that these molecules are located in the outflows, far away from the central stars. We consider the larger than expected percentage of mixed-chemistry targets as a selection bias toward stars with a disk or torus around them. Our results strengthen the current picture of mixed chemistry being due to the spatial segregation of different dust populations in the envelopes. Copyright (Copyright) 2009.

Here I suggest that it is worthwhile to look beyond simple characterizations of small-scale societies as being "low impact" in terms of their limited population, predation, and technology. Instead, we should look more closely both at the degree to which primary prey species are resilient to human predation and at the extent to which the niche construction efforts of small-scale human societies may modify vegetation communities in ways that result in their capture of a larger percentage of an ecosystem's total biotic energy. The small-scale Pre-Columbian societies occupying the Mississippi River Valley provide a case study. Throughout the Middle and Late Holocene, indigenous groups in this major north-south environmental corridor relied for protein to a substantial degree on a set of animal species/species groups (white-tailed deer, fish, migratory waterfowl) that combined both a high biotic potential and relative immunity from over-exploitation. At the same time, they practiced an integrated overall strategy of restructuring vegetation communities in ways that enhanced and expanded the habitats of many important food sources.

Ships arriving in New Zealand are now required to treat their ballast water to reduce the risk of transferring invasive aquatic organisms between ports. Most of these ships conduct mid-ocean ballast water exchange (BWE), replacing coastal water with open ocean water, but methods to verify BWE have been lacking. Samples were collected from ballast tanks and the ambient ocean on ships trading between southeastern Australia and New Zealand, to test the use of chemical (chromophoric dissolved organic matter or CDOM, Ba, Mn and P) concentrations to discriminate ballast water sources. Australian ballast water provides a difficult and valuable test case for BWE verification due to its high salinity and low chemical tracer concentrations resulting from Australia's low rainfall and nutrient-poor soils. Our results indicate that elevated CDOM, Ba and Mn were robust tracers of port waters, whereas elevated P was not a diagnostic tracer except of ballast water originating from Port Phillip Bay. Exchanged ballast tanks were diagnosed by CDOM fluorescence below 2.1 (for wavelength pair C2, Ex/Em = 320/414 nm) and 1.2 (for wavelength pair C3, Ex/Em = 370/494 nm) (quinine sulfate equivalents, QSE), and Ba and Mn concentrations below 5.7 and 3.5 kg l super(-1) respectively. These results are consistent with recent studies in the northern hemisphere, indicating that elevated concentrations of these tracers are robust indicators of unexchanged ballast water. Whereas clear differences existed between port and oceanic signatures, coastal and oceanic samples could not always be distinguished due to precipitously declining tracer concentrations within short distances from land.

The author uses research she did to curate the Cooper-Hewitt National Design Museum's 2005 exhibit Extreme Textiles: Designing for High Performance to further explore developments in textile engineering in aerospace, the military, athletics, and architecture that benefit from technology transfer, or moving a technology developed for one organization or environment into another. Through these collaborations, ways of using "smart" or "electronic" textiles, which can sense and react to their environments, have made significant advancements -- developments that have proven useful not only in the field for which they are intended but across industries. Craft, particularly embroidery, is an important piece of this work, often providing the answer to the questions of, for example, how to keep circuitry closed, as with the Antennae Vest, or how to maintain aesthetics of conductive fabrics, as with the Fuzzy Light Switch. The author demonstrates how textiles, as a craft, fit easily with contemporary technology.

Leptomaria stillwelli, L. seymourensis, Conotomaria sobralensis and C. bayeri, from the Paleocene [Danian], Sobral Formation, Seymour Island, are described as new. Leptomaria larseniana (Wilckens, 1911) new combination, also from the Sobral Formation, is redescribed based on better-preserved material. The limited diversity of the pleurotomariid fauna of Seymour Island is more similar to that of the Late Cretaceous faunas of Australia and New Zealand in terms of the number of genera and species, than to the older, more diverse faunas of South America, southern India, or northwestern Madagascar, supporting the status of the Weddelian Province as a distinct biogeographic unit. The increase in the species richness of this fauna during the Danian may be due to the final fragmentation of Gondwana during this period.

There have been many observed discrepancies between different observations of maximum plume height for the same eruption. A comparison of maximum daily height estimates of volcanic clouds over Indonesia and Papua New Guinea during 1982-2005 shows marked differences between ground and satellite estimates, and a general tendency towards lower height estimates from the ground. Without improvements in the quality of these estimates, reconciled among all available methods, warning systems will be less effective than they should be and the world's record of global volcanism will remain hard to quantify. Examination of particular cases suggests many possible reasons for the discrepancies. Consideration of the satellite and radar cloud observations for the 1991 Pinatubo eruptions shows that marked differences can exist even with apparently good observations. The problem can be understood largely as a sampling issue, as the most widely reported parameter, the maximum cloud height, is highly sensitive to the frequency of observation. Satellite and radar cloud heights also show a pronounced clumping near the height of the tropopause and relative lack of eruptions reaching only the mid-troposphere, reinforcing the importance of the tropopause in determining the eruption height in convectively unstable environments. To reduce the discrepancies between ground and satellite estimates, a number of formal collaboration measures between vulcanological, meteorological and aviation agencies are suggested.

Those models use input parameters, called "eruption source parameters", such as plume height H, mass eruption rate M, duration D, and the mass fraction m (sub 63) of erupted debris finer than about 4phi or 63 mu m, which can remain in the cloud for many hours or days. Observational constraints on the value of such parameters are frequently unavailable in the first minutes or hours after an eruption is detected. Moreover, observed plume height may change during an eruption, requiring rapid assignment of new parameters. This paper reports on a group effort to improve the accuracy of source parameters used by VATDs in the early hours of an eruption. We do so by first compiling a list of eruptions for which these parameters are well constrained, and then using these data to review and update previously studied parameter relationships. We find that the existing scatter in plots of H versus M yields an uncertainty within the 50% confidence interval of plus or minus a factor of four in eruption rate for a given plume height. This scatter is not clearly attributable to biases in measurement techniques or to well-recognized processes such as elutriation from pyroclastic flows. Sparse data on total grain-size distribution suggest that the mass fraction of fine debris m (sub 63) could vary by nearly two orders of magnitude between small basaltic eruptions ( approximately 0.01) and large silicic ones (>0.5). We classify eleven eruption types; four types each for different sizes of silicic and mafic eruptions; submarine eruptions; "brief" or Vulcanian eruptions; and eruptions that generate co-ignimbrite or co-pyroclastic flow plumes. For each eruption type we assign source parameters. We then assign a characteristic eruption type to each of the world's approximately 1500 Holocene volcanoes. These eruption types and associated parameters can be used for ash-cloud modeling in the event of an eruption, when no observational constraints on these parameters are available.

Although often reconstructed as steamy tropical rainforests, these ancient ecosystems were a far cry from anything we might encounter in the Amazon today. Bizarre giant club-mosses, horsetails and tree ferns were the dominant plants, not flowering trees as in modern rainforests. At their height, coal forests stretched all the way from Kansas to Kazakhstan, spanning the entire breadth of tropical Pangaea. Most of what we know of their biodiversity and ecology has been quite literally mined out of the ground through two centuries of hard labor. Without coal mining, our knowledge would be greatly impoverished. Over the past few years, we've been exploring underground coal mines in the United States, where entire forested landscapes have been preserved intact over huge areas. Never before have geologists had the opportunity to walk out through mile upon mile of fossilized forest. In this feature article, we describe some of our recent explorations and attempt to shed new light on these old fossils.

The field study was conducted in the Indian River Lagoon (Florida) in a mangrove-dominated impoundment that was established for purposes of mosquito control. The responses of mangroves to the regular addition of nitrate were insignificant or relatively minor compared to responses of the components of the microbial community. Denitrification rates, measured in the field and laboratory, increased significantly in fertilized plots and nitrous oxide emission rates were almost six times higher in fertilized plots. Nitrogen fixation was significantly lower in fertilized plots. Results suggest that mangrove systems in the N-limited Indian River Lagoon are likely to be long-term sinks for any increases in N loading.

The confusion was noted by Wilson (1808-1814) who restricted Latham's (1790) Sylvia pinus, based on C. pinus, to the Pine Warbler (in 1811) and proposed, as a new species (in 1810), S. solitaria, for the Blue-winged Warbler. Wilson's effective lectotypification, long ignored, following which Bonaparte (1824) unequivocally restricted C. pinus to the Pine Warbler, has resulted in misapplication of C. pinus. The correct name of the Pine Warbler should be Dendroica pinus (Linnaeus) and not D. pinus (Wilson) as in modern lists. Wilson's Sylvia solitaria is unfortunately preoccupied by Sylvia solitaria Lewin 1808 (= Origma solitaria, the Rockwarbler of Australia). A new scientific name is provided here for the Blue-winged Warbler because no other is available.

The primitive condition (presence) corroborates the basal placement of the creepers of the genera Oreomystis. and Paroreomyza. The derived condition of the plantaris (absence) was found in the Hawaii Creeper (Loxops mana), previously considered by some to be congeneric with Oreomystis, and agrees with other evidence placing that species in Loxops. The Hawaii Akepa (L. coccinneus), Anianiau (L. parvus), and Kauai Amakihi (L. stejnegeri) also lack the plantaris. This condition still appears to define a monophyletic group within the Drepanidini.

Females and males shared incubation and brooding duties with females on the nest during the day and males on at night. Nest relief occurred between 0300-0600 and 1800-2100 hrs. Two-egg clutches were placed on bare ground or on leaf-litter in more mature strands of forest. The semi-precocial young were mobile within 24 hrs of hatching and remained in the area with an adult through the fledgling stage. Both males and females feigned injury during incubation and brooding if disturbed. Three nesting sites were used for 5 years and another for 10 years, suggesting strong site fidelity and possibly a strong pair bond among long-lived individuals.

(Capparaceae) during exploration for caterpillars in the Area de Conservacion Guanacaste (ACG), Costa Rica. Cosmopterosis is revised and now includes four species. Three new species, C. hispida, C. jasonhalli, and C. spatha, and the immatures of C. spatha and biology for two species, C. jasonhalli and C. spatha, are described; the type species, C. thetysalls (Walker), is redescribed. A key and illustrations for the identification of the species is provided. We propose a hypothesis for the relationship between species in Cosmopterosis and the placement of Cosmopterosis in the subfamily. The cladistic analysis, the first such analysis in the Glaphyriinae, included 21 morphological characters one of which, the radiodiscal process, a male secondary sexual character and presumably an androconial scent pouch is described and considered a autapomorphy for the genus. Male secondary sexual characters and larval feeding on Capparis in Pyraloidea and Lepidoptera is discussed.

The primary instrument is a High Energy telescope (HET) that conducts the deepest survey for Gamma-ray Bursts (GRBs), obscured-accreting and dormant Supermassive Black Holes and Transients of all varieties for immediate followup studies by the two secondary instruments: a Soft X-ray Imager (SXI) and an Optical/Infrared Telescope (IRT). EXIST will explore the early Universe using high redshift GRBs as cosmic probes and survey black holes on all scales. The HET is a coded aperture telescope employing a large array of imaging CZT detectors (4.5 m super(2), 0.6 mm pixel) and a hybrid Tungsten mask. We review the current HET concept which follows an intensive design revision by the HET imaging working group and the recent engineering studies in the Instrument and Mission Design Lab at the Goddard Space Flight Center. The HET will locate GRBs and transients quickly (<10-30 sec) and accurately (< 20") for rapid (< 1-3 min) onboard followup soft X-ray and optical/IR (0.3-2.2 [mu]m) imaging and spectroscopy. The broad energy band (5-600 keV) and the wide field of view (90 x 70 at 10% coding fraction) are optimal for capturing GRBs, obscured AGNs and rare transients. The continuous scan of the entire sky every 3 hours will establish a finely-sampled long-term history of many X-ray sources, opening up new possibilities for variability studies.

Female solitary bees, megachilids and Centris, and their nest pollen provisions were monitored with trap nests over a 17-year period in a tropical Mexican biosphere reserve. Invasion by feral Apis (i.e. Africanized honey bees) occurred after the study began, and major droughts and hurricanes occurred throughout. Honey bee competition, and ostensibly pollination of native plants, caused changes in local pollination ecology. Shifts in floral hosts by native bees were common and driven by plant phylogenetics, whereby plants of the same families or higher taxa were substituted for those dominated by honey bees or lost as a result of natural processes. Two important plant families, Anacardiaceae and Euphorbiaceae, were lost to competing honey bees, but compensated for by greater use of Fabaceae, Rubiaceae, and Sapotaceae among native bees. Natural disasters made a large negative impact on native bee populations, but the sustained presence of Africanized honey bees did not. Over 171 plant species comprised the pollen diets of the honey bees, including those most important to Centris and megachilids (72 and 28 species, respectively). Honey bee pollination of Pouteria (Sapotaceae) plausibly augmented the native bees' primary pollen resource and prevented their decline. Invasive generalist pollinators may, however, cause specialized competitors to fail, especially in less biodiverse environments. No claim to original US government works.

One hypothesis is that forests are responding to widespread and intense human intervention prior to the European conquest (>500 y ago). In this study we confront this hypothesis with changes in AGB over 6.3 y in a large western Amazonian forest plot (>150 000 shrubs and trees and 1100 species with dbh greater than or equal to 10 mm in 25 ha). We examined AGB flux in different habitats and across diameter classes. The forest lost small stems (4.6%), gained large trees (2.6%), and gained biomass (0.7%). The change in AGB stock was due entirely to this upward shift in size leading to more canopy trees and fewer saplings after just 6 y. Across habitats, the biggest increment in biomass was in the secondary-forest patch (3.4% y-1) which we know was cleared about 27 y ago, whereas mature forest on ridges and valleys had small increases (0.10% and 0.09% y-1, respectively). In both censuses, AGB stocks were >50% higher on the ridge than in the valley while relative growth and mortality were higher in the valley. Mean wood specific gravity (WSG) decreased with increasing diameter class; WSG did not change much between censuses in mature forests and did not contribute to the change in AGB stocks. Our forest increased its standing biomass, but far less than the average reported for other Amazonian forests (i.e. 0.30 vs. 0.98 Mg ha-1 y-1). We find no evidence to support the notion that this forest is recovering from long-past human intervention. Instead of a long-term recovery, we believe the forest changed in response to natural fluctuations of the environment (e.g. changes in precipitation, higher CO2), windstorms or other more recent events. The significant differences in AGB stocks between valley and ridge suggest that the terra firme forests are a mosaic of natural habitats, and that this mosaic is in part responsible for the variation in biomass stocks detected in Amazonian terra firme forests. Resumen: La biomasa aerea de la mayoria de los bosques amazonicos esta incrementando. Una hipotesis es que los bosques estan respondiendo a un disturbio humano intenso y ampliamente distribuido, anterior a la llegada de los conquistadores europeos (>500 anos atras). En este estudio se confronta esta hipotesis con los cambios en biomasa encontrados en 6.3 anos en una parcela de gran escala de la Amazonia occidental (>150.000 arbustos y arboles con diametro a la altura del pecho greater than or equal to 10 mm y 1100 especies en 25 ha). Los resultados se examinan por categorias de diametro y habitat. En este periodo el bosque perdio tallos pequenos (4.6%), gano arboles grandes (2.6%) y gano biomasa (0.7%). La ganancia en biomasa fue debida enteramente al incremento de arboles de gran tamano que significo mas arboles de dosel y menos juveniles en apenas 6 anos. Entre los habitats, el mayor incremento en biomasa se encontro en un parche de bosque secundario de colina (3.4%/ano), cuya edad es de 27 anos, mientras el bosque maduro de las colinas y los valles incremento escasamente (0.10% y 0.09%/ano, respectivamente). Tanto al inicio como al final del estudio, el stock de biomasa fue >50% mas grande en la colina que en el valle mientras que el crecimiento y la mortalidad relativa fueron mayores en el valle. La media de la gravedad especifica de la madera (GEM) fue menor a mayor clase diametrica; en el bosque maduro, el cambio en la GEM fue insignificante y no contribuyo al aumento en stocks de biomasa. El bosque incremento la biomasa aerea pero mucho menos que el promedio reportado para otros bosques amazonicos (i.e. 0.30 vs. 0.98 Mg ha-1/ano). No se encontro evidencia que apoye la nocion de que el bosque se esta recuperando de un disturbio de gran escala ocurrido en el pasado. En su lugar, se cree que el bosque cambio en respuesta a fluctuaciones naturales del ambiente (e.g. cambios en precipitacion, mayor concentracion de CO2), vendavales u otro tipo de eventos mas recientes. La diferencia significativa en los stocks de biomasa encontrada entre el valle y la colina sugiere que la tierra firme es un mosaico de habitats naturales y que este mosaico podria explicar en parte la variacion encontrada en los stocks de biomasa de bosques amazonicos de tierra firme.

In this study we assessed the possible role that the presence of epiphytes may have on the diversity and abundance of canopy insects in an experimental study conducted in a coffee plantation in Coatepec, Veracruz, Mexico. Epiphytes were removed from trees in one of two plots in two sites of the coffee plantation. In each plot we collected insects from three Inga jinicuil trees by knockdown insecticide fogging. Insects were sorted to morphospecies, counted and measured. Trees with epiphytes had significantly higher numbers of species and individuals and insects larger than 5 mm were also more species-rich and abundant in trees with epiphytes. The magnitude of the enhancement was surprisingly large with the epiphyte plot samples having on average 90% more individuals and 22% more species than plots without epiphytes. These differences were even greater for large (>5 mm) insects (184% and 113% respectively). Our results support the tenet that epiphytes provide valuable resources to arthropods, which we have illustrated for canopy insects in shade trees of coffee plantations.

Sequences of the mitochondrial COI gene from 92 individuals of the trans-Pacific gastropod Conus ebraeus from eight localities spanning the tropical Pacific were analyzed to determine whether populations in the western, central, and eastern Pacific exhibit genetic structure, to examine the demographic histories of populations, and to infer patterns of gene flow. A total of 43 unique haplotypes were recovered, including a common haplotype that occurred in six of the eight populations examined. AMOVA and pairwise F-statistics showed that populations in the western and central Pacific were significantly differentiated from populations in the eastern Pacific, but no other evidence of structure. Bayesian isolation-migration (IM) analysis suggested that populations in the western and central Pacific separated from those in eastern Pacific during the Pleistocene. Examination of mismatch distributions and results from IM revealed that populations in the western and central Pacific expanded during the Pleistocene. Gene flow across the East Pacific Barrier appears to occur predominantly westward.

Ancient hunter-gatherers also altered their environments, although the extent to which they did so remains hotly debated (1-3). Hunter-gatherers may have caused major alterations of terrestrial ecosystems, including the use of fire to enhance resource productivity and the translocation of various animals to new regions (3, 4). They are implicated in massive megafaunal extinctions in the Americas and Australia (2, 3). Recent archaeological research from coastal areas shows that they also substantially altered and enhanced marine ecosystems in other ways, some of which obscure the definition of the term "hunter-gatherer."

The model incorporates the processes of plate addition and individual plate growth into a composite model of whole-body (somatic) growth. A simple developmental model based on hypothetical morphogens underlies the assumptions used to define the simulated growth processes. The data model is based on a Delaunay triangulation of plate growth center points, using the dual Voronoi polygons to define plate topologies. A spherical frame of reference is used for growth calculations, with affine deformation of the sphere (based on a Young-Laplace membrane model) to result in an urchin-like three-dimensional form. The model verifies that the patterns of coronal plates in general meet the criteria of Voronoi polygonalization, that a morphogen/threshold inhibition model for plate addition results in the alternating plate addition pattern characteristic of sea urchins, and that application of the Bertalanffy growth model to individual plates results in simulated somatic growth that approximates that seen in living urchins. The model suggests avenues of research that could explain some of the distinctions between modern sea urchins and the much more disparate groups of forms that characterized the Paleozoic Era.

Today, the free-living bryozoans often dominate epibenthic faunal communities in these expansive habitats, yet their biology and ecology remain poorly understood. This study examines their unique mode of life by exploring the relationship between form and function in the free-living Cupuladriidae of tropical America. Cupuladriid species occupy distinct niches in water depth and sediment type, and these variables correlate with a variety of morphological traits amongst species, thereby helping formulate hypotheses on functional morphology. These hypotheses were tested with disturbance, burial and mobility experiments. Species deal both passively and actively with disturbance and burial. Colony size and shape passively influences colony stability on the sea floor, susceptibility to burial and the ability to emerge once buried. Movable mandibles (setae) assist in emergence following burial, actively increase colony stability, and deter the settlement and disruption of encrusting growth of other organisms. Mandibles also enable colonies to move over the sea floor, but such behaviour appears to be of minimal benefit to avoid predation or to influence dispersal. Disturbance on the sea floor is the most important factor in driving the convergent evolution of the mobile free-living form. Colony shape and size and the employment of mandibles to improve stability, return to the surface after burial, and remove epibiota are central to the post-Mesozoic success of free-living bryozoans.

The data for HAT-P-7b show a smooth rise and fall of light from the planet as it orbits its star, punctuated by a drop of 130+ or -11 parts per million in flux when the planet passes behind its star. We interpret this as the phase variation of the dayside thermal emission plus reflected light from the planet as it orbits its star and is occulted. The depth of the occultation is similar in importance to the detection of a transiting Earth-size planet for which the mission was designed.

This deposit is the type locality for lammerite, described as a new species in 1981. Braithwaiteite is closely associated with lammerite, lavendulan-lemanskiite and quartz. It formed by oxidation of Sb-bearing enargite in an arid environment. Traces of pyrite, covellite, anatase, albite-oligoclase, kaolinite and a mineral of the chlorite group are present as well. Electron-microprobe analysis gives Na (sub 2) O 1.7, CuO 25.8, FeO 0.2, TiO (sub 2) 4.5, Sb (sub 2) O (sub 5) 11.7, As (sub 2) O (sub 5) 42.3, H (sub 2) O (calc.) 10.17, for a total of 96.37 wt.%. The empirical formula based on the results of crystal-structure solution and refinement [34 anions and 2(OH) + 8H (sub 2) O] is Na (sub 0.87) Cu (super 2+) (sub 5.17) (Ti (super 4+) (sub 0.90) Sb (super 5+) (sub 1.15) ) (sub Sigma 2.05) O (sub 2) (As (super 5+) (sub 0.98) O (sub 4) ) (sub 4) [As (super 5+) (sub 0.98) O (sub 3) (OH)] (sub 2) (H (sub 2) O) (sub 8) . The simplified formula is NaCu (sub 5) (TiSb)O (sub 2) (AsO (sub 4) ) (sub 4) [AsO (sub 3) (OH)] (sub 2) (H (sub 2) O) (sub 8) , which requires Na (sub 2) O 2.04, CuO 26.13, TiO (sub 2) 5.25, Sb (sub 2) O (sub 5) 10.63, As (sub 2) O (sub 5) 45.30, H (sub 2) O 10.65, total 100.00 wt.%. Infrared spectroscopy indicates the presence of H (sub 2) O and OH, and As-O and As-OH stretching vibrations. Single-crystal X-ray studies show braithwaiteite to be triclinic, space group P, a 7.0308(4), b 9.8823(5), c 10.6754(6) Aa, alpha 106.973(1), beta 104.274(1), gamma 93.839(1) degrees , V 679.76(11) Aa (super 3) , Z = 1, and a:b:c = 0.7115:1:1.0803. The strongest seven X-ray powder-diffraction lines [d in Aa(I)(hkl)] are: 9.825(100)(001), 5.887(50)(011), 4.635(30), 3.354(30), 3.232(30), 2.947(60)(022), 2.736(30). Two crystals of braithwaiteite were found, one on matrix and the other loose, each of them less than 1 mm in size, plus a few very minute fragments. The forms that could be determined with certainty include the following pinacoids: {001} dominant, {010} less prominent, {100}, {10} and {203}, all subordinate. The crystals are transparent and have a sky-blue color, a vitreous luster and a very pale blue streak. Braithwaiteite is brittle and has a perfect cleavage parallel to {001}. Optically, braithwaiteite is biaxial negative, 2V (sub meas) 59(2), 2V (sub calc) 65 degrees . Indices of refraction are alpha 1.698(2), beta 1.757(5), gamma 1.783(5) at 589.3 nm. The mineral is weakly pleochroic with pale blue to greenish blue hues. The hardness (Mohs) is approximately 2. Using the empirical formula and the unit-cell parameters derived from the single-crystal study, the calculated density is 3.753 g cm (super -3) . Braithwaiteite is named after Dr. Richard S. W. Braithwaite (born 1930), prominent chemist and mineralogist at the University of Manchester, U.K. The mineral and mineral name have been approved by the Commission on New Minerals, Nomenclature and Classification, IMA (2006-050).

Multispectral imaging shows that the interior plains are spectrally distinct from surrounding terrain, with a reflectance about 15-20% higher and a steeper spectral slope than the global average. The Caloris basin rim massifs and hummocky material, in contrast, have lower reflectance and a shallower spectral slope than the global average and extend around the entire basin. Isolated, relatively red patches along the margins of Caloris each surround irregularly shaped, scalloped-edged, rimless depressions that are interpreted to be volcanic vents, some with associated pyroclastic deposits. A nearly continuous annulus of smooth plains exterior to the basin displays spectral characteristics that contrast sharply with those of the basin-interior smooth plains. The exterior smooth plains are lower in reflectance and spectrally similar to the Caloris rim massifs and the hummocky materials. The rims and floors of larger impact craters in the interior plains expose low-reflectance material. There is widespread evidence of contractional and extensional tectonic deformation of the Caloris interior smooth plains. A set of linear radial graben, Pantheon Fossae, radiates outward from a zone near the basin center, and some of these graben extend to and intersect a set of generally basin-concentric graben distributed along the outer margin of the Caloris basin floor. The average areal extensional strain expressed by the mapped system of graben is approximately 0.08%. Wrinkle ridges also deform the interior smooth plains and predate both basin-radial and basin-concentric graben. The average areal contractional strain expressed by the mapped wrinkle ridges is approximately 0.07%. The density of wrinkle ridges on the western interior smooth plains is less than on the eastern interior plains, in contrast to the more even distribution of graben. A similar difference is seen between the density of wrinkle ridges on the western and eastern exterior smooth plains, with far fewer wrinkle ridges per unit area on the western annular plains. Superposition relations, spectral contrast, and the occurrence of volcanic vents and possible pyroclastic deposits all support a volcanic origin for the Caloris interior plains. Crater counts indicate that the Caloris exterior plains and hummocky material are younger than the Caloris rim and interior plains and are therefore also likely volcanic in origin. The contrast in spectral properties between the interior and exterior plains indicates a difference in the composition of the two expanses of volcanic material. Models for extensional tectonic deformation of the Caloris basin interior inferred from the distribution of graben viewed by Mariner 10 must be reevaluated to account for the discovery of Pantheon Fossae.

Wrinkle ridges are found on the smooth plains that partially fill the interior and surround the exterior of the Caloris basin and also on smooth plains that fill the interiors of smaller impact basins and larger craters. MESSENGER revealed a radial graben complex, Pantheon Fossae, nearly co-centered with the Caloris basin. Pantheon Fossae and a network of mostly basin-concentric graben in the outer portions of the Caloris basin interior form a pattern of extension not seen elsewhere on Mercury. The first clear example of extensional faults outside of the Caloris basin has been documented on smooth plains inside the peak ring of the relatively young Raditladi basin. A map of the distribution of tectonic landforms imaged by MESSENGER and Mariner 10 shows that lobate scarps are the most widespread type of feature. Estimates of the horizontal shortening associated with lobate scarps that crosscut and overthrust small impact craters imaged by MESSENGER range from approximately 1 to 3 km. Previously unrecognized lobate scarps detected in areas imaged by Mariner 10 indicate that earlier estimates of contractional strain are low. A new estimate of the average areal contractional strain ( approximately 0.06%) accommodated by scarps is at least one third greater than comparable previous estimates and corresponds to a decrease in Mercury's radius of at least 0.8 km since the end of heavy impact bombardment of the inner solar system. These figures are lower bounds because of the likelihood that not all lobate scarps have been identified even in areas imaged to date. Crosscutting and embayment relations revealed by MESSENGER suggest that lobate scarps formed before the end of smooth plains emplacement and continued to be active after the emplacement of the youngest smooth plains deposits. Relatively recent activity on lobate scarps may be the expression of slow but continuous radial contraction that accompanied cooling of Mercury's interior and the growth of the planet's solid inner core.

Uncertain after that mission were the size of the basin, the full distribution of materials deposited or modified during the impact process, and the stratigraphic and age relationships between Caloris and surrounding terrain. Images obtained during MESSENGER's January 2008 flyby of Mercury revealed that the Caloris basin is approximately 15% larger than previously estimated and moderately elliptical ( approximately 1525 by approximately 1315 km). Basin-related sculpture and secondary craters are dispersed widely in areas surrounding the basin, confirming the widespread significance of this event as a stratigraphic marker. Units mapped around Caloris on the basis of Mariner 10 data are generally recognized in regions observed for the first time by MESSENGER, including most facies of the Caloris Group (the Caloris Montes, Odin Formation, and Van Eyck Formation). The only unit without obvious exposures in MESSENGER images is the Nervo Formation, which was originally interpreted as impact melt or fallback ejecta. New measurements of the size-frequency distribution of impact craters both within the Caloris basin and on surrounding units, particularly the Odin Formation, support the hypothesis that the vast majority of circum-Caloris plains postdate the basin and are likely volcanic. The MESSENGER observations re-emphasize the importance of understanding the exterior stratigraphy of the basin in order to utilize the Caloris event as a discrete time horizon in the geological history of Mercury.

These new data have helped to address and resolve a series of longstanding questions on the existence and nature of volcanism on Mercury and the distribution of volcanic materials. Data from the Mercury Dual Imaging System (MDIS) on the MESSENGER spacecraft have shown the following: (1) Numerous volcanic vents, in the form of irregularly shaped rimless depressions, are concentrated around the interior edge of the Caloris basin. (2) These vents appear to be sources for effusive volcanism that in one case built a shield in excess of 100 km in diameter and in some cases formed bright haloes around the vents that are interpreted to represent pyroclastic eruptions. (3) Lobate margins of plains units, seen previously in Mariner 10 data, are documented in MESSENGER images with more clarity and are often distinctive in morphology and color properties, supporting the interpretation that these features are the edges of lava flow units. (4) The interior of the Caloris basin is filled with plains units spectrally distinctive from the rim deposits, and comparison with the lunar Imbrium basin and superposed impact crater stratigraphy provide evidence that these units are volcanic in origin; detailed differences in the mineralogy of lava flow units, so prominent in Imbrium, are not seen in the Caloris interior. (5) Some of the smooth plains surrounding the exterior of the Caloris basin show distinct differences in color and morphological properties, supporting a volcanic origin. (6) Some smooth and intercrater plains units distant from the Caloris basin show evidence of flooding and embayment relations unrelated to Caloris ejecta emplacement; local and regional geological and color relationships support a volcanic origin for these plains. (7) Large impact craters show a sequence of embayment of interior floor and exterior ejecta deposits that supports a volcanic origin for the embayment and filling processes. (8) Crater embayment and flooding relationships in selected areas suggest volcanic plains thicknesses of many hundreds of meters and local thicknesses inside impact craters of up to several kilometers. (9) Impact crater size-frequency distributions for Caloris exterior deposits, including the facies of the Caloris Group and relatively high- and low-albedo smooth plains, show that they are younger than plains interior to Caloris and thus must be dominantly the product of post-Caloris volcanism. These new data provide evidence that supports and confirms earlier hypotheses from Mariner 10 data that volcanism was important in shaping the surface of Mercury. The emerging picture of the volcanic style of Mercury is similar to that of the Moon, the other small, one-plate planetary body: there are no major shield volcanoes (e.g., comparable to Tharsis Montes on Mars), shallow magma reservoirs are rare, and there is little evidence for surface deformation or long-lived volcanic sources related to sites of upwelling mantle. The close association of volcanic plains and surface deformation features suggests that future observations and analyses can help document the relation between the volcanic flux and the evolving state and magnitude of stress in the lithosphere of Mercury.

Here we report on evidence in the new data for several features that are characterized by fractures and graben - rare features on a planet dominated by contractional deformation - that may be linked to intrusive activity. These features include: (1) A floor-fractured crater, interpreted to have been the site of laccolith-like sill intrusions; the feature is similar to some floor-fractured craters on the Moon and shows evidence for individual fractured dome-like uplifts on the floor. (2) A concentric complex of graben, observed inside the peak ring on the floor of the approximately 250-km-diameter Raditladi basin and associated with dark plains and possibly embayed by them; the feature may represent an unusual type of floor-fracturing associated with deeper intrusions and related ring dikes or cone sheets, or the graben may instead be the product of non-magmatic uplift of the basin floor. (3) A large radial graben swarm, Pantheon Fossae, located near the center of the Caloris basin, thus far unique on Mercury, and characterized by hundreds of individual graben segments ranging from approximately 5 km to approximately 110 km in length. In the nexus, graben crosscut one another and produce a local polygonal pattern; others curve away from the center as the nexus is approached. Two scales of graben length are observed; the radius of the dense radially symmetric plexus of graben is approximately 175 km, and a few graben extend to greater radial distances to the north and southwest out to distances that intersect with a ring of generally concentric graben around the outer basin floor. Two width scales of graben are observed; a large graben about 8 km wide emerges from the nexus and extends for approximately 100 km; most graben are less than half this width. Some graben walls appear cuspate, with convex-outward wall segments that resemble crater chain segments. One crater chain with distinctive raised rims parallels nearby graben. Locally, some graben appear in en echelon patterns, and smaller graben sometimes show cross-cutting (superposition) relationships. Abundant impact craters, the most prominent being Apollodorus, and secondary crater clusters and chains are superposed on the graben system; there is little evidence that craters greater than 5 km in diameter have been cut by a graben. This relation implies that the graben swarm formed soon after the emplacement of the Caloris floor plains. These graben are interpreted to be the surface expression of a radial dike swarm emanating from a subsurface magma reservoir. Similar features, in which the dikes contribute to a near-surface stress field that favors radial graben, are known on the Earth, Venus, and Mars. The location of Pantheon Fossae in the center of the Caloris basin suggests that formation of the radial graben structure is linked to basin evolution.

AN - 50064949; 2010-026185 AB - The approximately 40-km-diameter Apollodorus impact crater lies near the center of Pantheon Fossae, a complex of radiating linear troughs itself at the approximate center of the 1500-km-diameter Caloris basin on Mercury. Here we use a series of finite element models to explore the idea that the Apollodorus crater-forming impact induced the formation of radially oriented graben by altering a pre-existing extensional stress state. Graben in the outer portions of the Caloris basin, which display predominantly circumferential orientations, have been taken as evidence that the basin interior was in a state of horizontal extensional stress as a result of uplift. If the Apollodorus crater formed at the time of such a stress state, impact-induced damage to basin fill material would have caused basin material to move radially outward, leading to a decrease in the radial extensional stress and an increase in the circumferential stress. If this change in differential stress was sufficient to induce failure, the predicted style of faulting would be radial graben extending outward from the exterior crater rim. The approximately 230-km radial extent of Pantheon Fossae implies, by this scenario, that the Apollodorus impact generated a large damage zone, extending to perhaps three crater radii ( approximately 60 km) or more. The calculations also suggest, under this scenario, that the Caloris basin fill had greater strength than the surrounding crust and that the basin uplift and extensional stress field prior to the Apollodorus impact were close to azimuthally symmetric. The location of Pantheon Fossae very near the center of the Caloris basin appears to be coincidental; any crater similar in size to Apollodorus and located within approximately 300 km of the basin center could have produced a radiating set of graben by the mechanism explored here.

Such transformations often appear to be fluctuations between tradition and modernity explained alternatively as instances of 'acculturation' or as expressions of 'invented traditions' and 'postmodern identity politics.' By focusing mainly on external factors, these theoretical approaches pay insufficient attention to the role of native perceptions and practices in promoting cultural change. Approaches that do take into consideration these perceptions, such as those centered on the notions of 'passing' and 'mimesis,' do not apply to this particular case. Adopting a Yanesha perspective as a departure point, I argue that what appear to be expressions of acculturative processes are the result of a long-standing indigenous openness to the Other-particularly the white and mestizo Others-and the native conviction that the Self is possible only through the incorporation of the Other. Such incorporation always finds expression in bodily transformations, hybrid bodyscapes that change throughout time according to the shifting relationships between Self and Other.

The pre-GPS device data are imprecise relative to GPS data. Niche modeling is a powerful technique for predicting geographic distributions that provides the best results when the locality data are precise. The purpose of this study is to determine whether imprecise historical locality data are sufficient such that niche modeling techniques can yield realistic new insights to species-level distributions. Two sets of frogs of the genus Leptodactylus that have known different kinds of distributions are evaluated: two species with broad, presumably continuous distributions, and four species known to occur in patchy, disjunct habitats in South America. BIOCLIM, a presence-only environmental niche modeling algorithm,was used to define suitable occupancy areas based on multiple sets of environmental parameters that include: monthly mean, max, and min temperatures, and monthly precipitation. A Nature Conservancy - Natureserve ecoregion layer and a high resolution elevation layer were also included in the analyses. Our analyses yield new realistic insights and questions regarding distributions of the Leptodactylus species we evaluated.

These stressors do not act independently; instead, they jointly influence food webs, and each affects the sensitivity of species and ecosystems to the other. Nutrient enrichment and the habitat degradation it sometimes causes can affect sustainable yields of fisheries, and fisheries exploitation can affect the ability of estuarine systems to process nutrients. The total biomass of fisheries landings in estuaries and semi-enclosed seas tends to increase with nitrogen loadings in spite of hypoxia, but hypoxia and other negative effects of nutrient over-enrichment cause declines in individual species and in parts of systems most severely affected. More thoroughly integrated management of nutrients and fisheries will permit more effective management responses to systems affected by both stressors, including the application of fisheries regulations to rebuild stocks negatively affected by eutrophication. Reducing fishing mortality may lead to the recovery of depressed populations even when eutrophication contributes to population declines if actions are taken while the population retains sufficient reproductive potential. New advances in modeling, statistics, and technology promise to provide the information needed to improve the understanding and management of systems subject to both nutrient enrichment and fisheries exploitation.

Most of these strikes occurred during takeoff or landing of the flight, and it is during these flight phases that aircraft experience their highest risk of substantial damage after colliding with birds. Birdstrikes carry enormous potential costs in terms of lives and money. Using feather remains and other tissue samples collected from the engines of US Airways Flight 1549, which crash landed in the Hudson River in New York City on 15 January 2009 after a birdstrike, we apply molecular tools and stable hydrogen isotopes to demonstrate that migratory Canada geese were responsible for the crash. Determining whether the geese involved in this birdstrike event were resident or migratory is essential to the development of management techniques that could reduce the risk of future collisions. Currently, the US civil aviation industry is not required to report birdstrikes, yet information on frequency, timing, and species involved, as well as the geographic origin of the birds, is critical to reducing the number of birdstrikes. Integrating this information with bird migration patterns, bird-detecting radar, and bird dispersal programs at airports can minimize the risk of such collisions in the future.

AN - 20683279; 10206258 AB - A scrub-oak woodland has maintained higher aboveground biomass accumulation after 11 years of atmospheric CO2 enrichment (ambient +350 kmol CO2 mol-1), despite the expectation of strong nitrogen (N) limitation at the site. We hypothesized that changes in plant available N and exploitation of deep sources of inorganic N in soils have sustained greater growth at elevated CO2. We employed a suite of assays performed in the sixth and 11th year of a CO2 enrichment experiment designed to assess soil N dynamics and N availability in the entire soil profile. In the 11th year, we found no differences in gross N flux, but significantly greater microbial respiration (P,0.01) at elevated CO2. Elevated CO2 lowered extractable inorganic N concentrations (P=0.096) considering the whole soil profile (0-190 cm). Conversely, potential net N mineralization, although not significant in considering the entire profile (P=0.460), tended to be greater at elevated CO2. Ion-exchange resins placed in the soil profile for approximately 1 year revealed that potential N availability at the water table was almost 3 x greater than found elsewhere in the profile, and we found direct evidence using a 15N tracer study that plants took up N from the water table. Increased microbial respiration and shorter mean residence times of inorganic N at shallower depths suggests that enhanced SOM decomposition may promote a sustained supply of inorganic N at elevated CO2. Deep soil N availability at the water table is considerable, and provides a readily available source of N for plant uptake. Increased plant growth at elevated CO2 in this ecosystem may be sustained through greater inorganic N supply from shallow soils and N uptake from deep soil.

In Hawaii, the nudibranch Phestilla sibogae only feeds on Porites compressa and requires a water-soluble cue from this coral for metamorphosis. On Guam, we tested three different species of Phestilla to determine if their larvae require water-soluble compounds from corals to induce metamorphosis. Larvae of P. sibogae metamorphosed at high rates to waterborne cues from multiple species of corals in the genus Porites. Larvae of Phestilla minor could distinguish among waterborne compounds from different species of Porites, but also had high rates of metamorphosis in filtered seawater and in response to corals that adults did not eat. Larvae of Phestilla sp. 2 could distinguish among water-soluble cues from different species of Goniopora and consistently had the highest rates of metamorphosis in response to waterborne cues released from Goniopora fruticosa. P. minor was the only species studied that did not require waterborne cues for larval metamorphosis.

For example, leaf- cutting ants maintain an obligate symbiosis with their fungal garden, while the leaf material they provide to their garden is usually filled with endophytic fungi. The ants and their cultivar may interact with hundreds of endophytic fungal species, yet little is known about these interactions. Experimental manipulations showed that (i) ants spend more time cutting leaves from a tropical vine, Merremia umbellata, with high versus low endophyte densities, (ii) ants reduce the amount of endophytic fungi in leaves before planting them in their gardens, (iii) the antsa fungal cultivar inhibits the growth of most endophytes tested. Moreover, the inhibition by the antsa cultivar was relatively greater for more rapidly growing endophyte strains that could potentially out-compete or overtake the garden. Our results suggest that endophytes are not welcome in the garden, and that the ants and their cultivar combine ant hygiene behaviour with fungal inhibition to reduce endophyte activity in the nest.

Yet, our understanding of which male attributes contribute to reproductive success is still fragmentary in most cases. Male-male reproductive coalitions, where males jointly display to attract females, are of particular interest to evolutionary biologists because one male appears to forego reproduction to assist the social partner. By examining the relationship between social behaviour and reproductive success, we can elucidate the proximate function of coalitions in the context of mate choice. Here, we use data from a 4-year study of wire-tailed manakins (Pipra filicauda) to provide molecular estimates of reproductive skew and to test the hypothesis that male-male social interactions, in the context of coordinated displays, positively influence a maleâs reproductive success. More specifically, we quantify male-male social interactions using network metrics and predict that greater connectivity will result in higher relative reproductive success. Our data show that four out of six leks studied had significant reproductive skew, with success apportioned to very few individuals in each lek. Metrics of male social affiliations derived from our network analysis, especially male connectivity, measured as the number of males with whom the focal male has extended interactions, were strong predictors of the number of offspring sired. Thus, network connectivity is associated with male fitness in wire-tailed manakins. This pattern may be the result of shared cues used by both sexes to assess male quality, or the result of strict female choice for coordinated display behaviour.

Promethea were polyandrous, the first documentation for a saturniid moth, whereas tulip tree moths were monandrous. Experiments showed that polyandrous and monandrous promethea females achieved similar egg fertility, but polyandrous females laid 10% more eggs, a significant difference (P < 0.05). This difference was found in five sibling groups, whose larvae were reared on the same individual food plant. Higher fecundity for polyandrous promethea females was not related to female size, duration of copulation, egg size and number, number of days in laying period or sibling group. Egg size declined later in the laying period for all females. Small females laid more eggs earlier in the laying period than large females. A separate mark/recapture study showed that male promethea also mate multiple times (polygyny) and distinguish virgin from nonvirgin females in mating preference. The diurnally mating promethea may gain increased genetic variability and/or possibly seminal gifts from polyandry. Monandry in totally nocturnal saturniid moths may result from a time conflict between egg laying and mating, which overrides the benefits of polyandry. If polyandry increases fecundity, it is predicted to occur in other diurnally mating saturniids.

Historically, the ciguatoxins are produced by Gambierdiscus toxicus have been assumed to be the primary cause of CFP world wide. Other species produce a variety of toxins, including maitotoxins, saxitoxins or okadaic acid, which are suspected of contributing to CFP, but not yet definitively confirmed. These include Coolia monotis, Gambierdiscus belizeanus, Prorocentrum belizeanum, P. lima, P. mexicanum, P. hoffmannianum, and Ostreopsis lenticularis, O. siamensis in the Caribbean; and Amphidinium carterae, A. klebsii, Coolia monotis, G. polynesiensis, G. australes, G. pacificus, G. yasumotoi, Ostreopsis lenticularis, O. heptagona, O. ovata, O. mascarenensis, O. siamensis, P. lima and P. minimum in the Pacific. Knowing the distribution of CFP-dinoflagellates as producers of toxins is important and yet has to be fully characterized in tropical waters. This study examined epiphytic and benthic CFP-dinoflagellate associations on macrophytes, in sand, on floating detritus and forming blooms in the Belizean barrier coral-reef system. The degree of overlap between these CFP-species in the Caribbean is compared with studies from the Pacific, Mediterranean, New Zealand and Australian tropical waters.

Movements of males are poorly understood, particularly the degree to which yearlings (first breeding season) and older males (second or later breeding season) wander altitudinally during the breeding season. Liver and muscle d super(13)C values of warblers exhibited significant year and altitude effects, but yearling and older males were isotopically indistinguishable. Liver d super(13)C values increased with altitude at the rate of 60.5% sub(0) per 1000 m. The altitudinal lapse rate of muscle d super(I3)C (61.1% sub(0) per 1000 m) was nearly identical to the average rate of increase reported in several groups of C sub(3) plants (61.1% sub(0) per 1000 m). This suggests that the majority of males foraged within relatively narrow altitudinal zones during the breeding season. We caution, however, that the discrimination of altitudinal trends in carbon isotope ratios depends on relatively large multiyear samples. Given the scatter in data, it is unlikely that individuals can be accurately assigned to a particular altitude from carbon isotope values. Rapid adjustment of liver and muscle d super(13)C values to local altitudinal environments is consistent with the results of experimental dietary studies that show carbon turnover rates are relatively rapid in small migratory passerines. In a broader context, c arbon isotope data have been increasingly used as proxies for wintering habitat use of Nearctic-Neotropical migratory passerines. However, tissues with high metabolic rates are unlikely to retain much isotopic signal of wintering habitat use by the time migrants reach their breeding territories.

A total of 220 individuals from three species of African rain-forest bird (Andropadus latirostris, Andropadus virens, Cyanomitra obscura), captured in two pristine and two agroforests in Cameroon, were screened for the presence of avian haemosporidian parasites (species of Plasmodium and Haemoproteus) to test whether habitat differences were associated with differences in the prevalence of infectious diseases in natural populations. Thirteen mitochondrial lineages, including 11 Plasmodium and two Haemoproteus lineages were identified. Whereas levels of Haemoproteus spp. infections were too low to permit analysis, the prevalence of infections with Plasmodium spp. reached significantly greater levels in undisturbed mature forests. Importantly however, the significant association between forest type and parasite prevalence was independent of host density effects, suggesting that the association did not reflect changes in host species composition and abundance between forest types. Our results illustrate how characterizing land-cover differences, and hence changes, may be a prerequisite to understanding and predicting patterns of parasite infections in natural populations of rain-forest birds.

Largely as the result of anaerobic decomposition, wetland soils store globally significant amounts of organic carbon and are currently net sources of CH sub(4) to the atmosphere. Given the importance of wetlands in the global carbon cycle, it is important to understand controls on anaerobic decomposition in order to predict feedbacks between wetland soils and global climate change. One perplexing pattern observed in many wetland soils is the high proportion of CO sub(2) resulting from anaerobic decomposition that cannot be explained by any measured pathway of microbial respiration. Recent studies have hypothesized that humic substances, and in particular solid-phase humic substances in wetland soils, can support anaerobic microbial respiration by acting as organic electron acceptors. Humic substances may thus account for much of the currently unexplained CO sub(2) measured during decomposition in wetland soils. Here we demonstrate that humic acids extracted from a variety of wetland soils act as either electron donors or electron acceptors and alter the ratio of CO sub(2):CH sub(4) produced during anaerobic laboratory incubations. Our results suggest that soil-derived humic substances may play an important, and currently unexplored, role in anaerobic decomposition in wetland soils.

Eighteen species were captured in forest and seven species in savanna. Species numbers and total number of individuals captured were tightly correlated. In forest, species and abundance varied interannually by up to fourfold in one plot and to 100-fold in the other, and showed alternating highs and lows as is typical for small mammals. The largest faunal differences were due not to site differences, but to year differences, with markedly different patterns in forests and savannas. Abundance was not correlated with rainfall overall, but showed correlation in exceptional years of rainfall and ENSO drought. In savanna, species and overall abundance declined without recovery during 3 yr after reaching minimum numbers in 2004. One species, Cavia aperea, became extinct on both plots, and subsequently, apparently on the entire savanna. Both herbivorous and insectivorous species declined together. Rainfall, fire, and flooding do not seem to account for savanna rodent declines. I propose the novel hypothesis that smoke from anthropogenic burning raises nocturnal temperatures and prevents dew formation, and that a decrease in nightly dry season dewfall has been instrumental in rodent declines. Anecdotal and climatic data are consistent with this hypothesis, but it cannot yet be tested.Abstract in French is available at http://www.blackwell-synery.com/loi/btp.

Here we use molecular and morphological data to contrast the effect of isolation (by mountains and geographical distance) with that of ecological factors (altitudinal gradients) in promoting differentiation in the wedge-billed woodcreeper, Glyphorynchus spirurus, a tropical forest bird, in Ecuador. Tarsus length and beak size increased relative to body size with altitude on both sides of the Andes, and were correlated with the amount of moss on tree trunks, suggesting the role of selection in driving adaptive divergence. In contrast, molecular data revealed a considerable degree of admixture along these altitudinal gradients, suggesting that adaptive divergence in morphological traits has occurred in the presence of gene flow. As suggested by mitochondrial DNA sequence data, the Andes act as a barrier to gene flow between ancient subspecific lineages. Genome-wide amplified fragment length polymorphism markers reflected more recent patterns of gene flow and revealed fine-scale patterns of population differentiation that were not detectable with mitochondrial DNA, including the differentiation of isolated coastal populations west of the Andes. Our results support the predominant role of geographical isolation in driving genetic differentiation in G. spirurus, yet suggest the role of selection in driving parallel morphological divergence along ecological gradients.

In this paper, we describe fossil leaves, inflorescences, and fruits of palms from the middle to late Paleocene Cerrejon Formation, outcropping in the Rancheria River Valley, northern Colombia. The fossils demonstrate the presence of at least five palm morphospecies in the basin ca. 60 Ma. We compare the morphology of the fossils with extant palms and conclude that they belong to at least three palm lineages: the pantropical Cocoseae of the subfamily Arecoideae, the monotypic genus Nypa, and either Calamoideae or Coryphoideae. The fossil fruits and inflorescences are among the oldest megafossil records of these groups and demonstrate that the divergence of the Cocoseae was more than 60 Ma, earlier than has previously been thought.

Previous work has hypothesized that (i) Pseudonocardia antibiotics are narrow-spectrum and control a fungus (Escovopsis) that parasitizes the antsa fungal symbiont, and (ii) MG secretions have broad-spectrum activity and protect ants and brood. We assessed the relative importance of these lines of defence, and their activity spectra, by scoring abundance of visible Pseudonocardia for nine species from five genera and measuring rates of MG grooming after challenging ants with disease agents of differing virulence. Atta and Sericomyrmex have lost or greatly reduced the abundance of visible bacteria. When challenged with diverse disease agents, including Escovopsis, they significantly increased MG grooming rates and expanded the range of targets. By contrast, species of Acromyrmex and Trachymyrmex maintain abundant Pseudonocardia. When challenged, these species had lower MG grooming rates, targeted primarily to brood. More elaborate MG defences and reduced reliance on mutualistic Pseudonocardia are correlated with larger colony size among attine genera, raising questions about the efficacy of managing disease in large societies with chemical cocktails versus bacterial antimicrobial metabolites.

Inter-patch distance (lag) may be especially important in the interacting effects of aggregation and interference among predators on their search and prey-handling ability. Interactions of blue crabs Callinectes sapidus preying upon thin-shelled clams Macoma balthica in Chesapeake Bay provide a test of how the opposing forces of aggregation and interference interact with the spatial distribution of prey patches to influence rates of prey consumption. Blue crabs can detect clam patches from up to 15 m away using chemosensory cues, and they aggregate on them, thus facilitating predation, but exhibit agonistic behaviors when closer than 5 m to another crab, thus reducing feeding efficiency. We used these patterns of aggregation and interference to modify a generalized functional response model to describe individual crab foraging efficiency as a function of distance between patches. The model predicted highest predation rates at an intermediate lag of 6.6 m. We tested this a priori hypothesis with a set of field experiments wherein prey patches were established with lags of 1, 7, 10, and 50 m. Predation rates were highest at intermediate lags, as predicted. This work highlights the importance of the interaction between spatial scales and ecological processes, demonstrating that spatial heterogeneity is not noise that obscures processes, but an active component of the predator-prey dynamic.

Here, a consolidated description of histology evaluation practices, core diagnostic criteria and severity grading schemes for the AMA, an atlas of the normal architecture of amphibian thyroid glands over the course of metamorphosis, and the core diagnostic criteria with examples of severity grades is provided. Core diagnostic criteria include thyroid gland hypertrophy/atrophy, follicular cell hypertrophy, and follicular cell hyperplasia. The severity grading scheme is semiquantitative and employs a four-grade approach describing ranges of variation within assigned ordinal classes: not remarkable, mild, moderate, and severe. The purpose of this severity grading approach is to provide an efficient, semi-objective tool for comparing changes (compound-related effects) among animals, treatment groups, and studies. Proposed descriptions of lesions for scoring the four core criteria are also given.

Mg/Ca ratios of individual growth increments were analyzed by measuring a single-point, electron-microprobe transect, yielding a resolution of approximately 15 samples/year and a 65-year record (1902-1967) of variations. Results show that Mg/Ca ratios in the high-Mg calcite algal framework display pronounced annual cyclicity and archive late spring-late fall sea-surface temperatures (SST) corresponding to the main season of algal growth. Mg/Ca values correlate well to local SST, as well as to an air temperature record from the same region. High spatial correlation to large-scale SST variability in the subarctic North Pacific is observed, with patterns of strongest correlation following the direction of major oceanographic features that play a key role in the exchange of water masses between the North Pacific and the Bering Sea. Our data correlate well with a shorter Mg/Ca record from a second site, corroborating the ability of the alga to reliably record regional environmental signals. In addition, Mg/Ca ratios relate well to a 29-year delta (super 18) O time series measured on the same sample, providing additional support for the use of Mg in coralline red algae as a paleotemperature proxy that, unlike algal-delta (super 18) O, is not influenced by salinity fluctuations. Moreover, electron microprobe-based analysis enables higher sampling resolution and faster analysis, thus providing a promising approach for future studies of longer C. nereostratum records and applications to other coralline species.

For instance, it has been proposed that changes in plant community (e.g., gymnosperm-dominated vs. angiosperm-dominated) could have significantly altered/amplified the carbon-isotope ratios of bulk sedimentary organic matter derived from land plants (delta (super 13) C (sub TOM) ), compared to that of the marine carbonates (delta (super 13) C (sub carbonate) ). Here, delta (super 13) C (sub TOM) values in a terrestrial sequence of the Colombian tropics are compared to the composite Paleocene-Eocene delta (super 13) C (sub carbonate) curve from Zachos et al. (2001) to evaluate the use of delta (super 13) C (sub TOM) values as a reliable chronostratigraphic tool. Sediments of the studied terrestrial sequences were deposited in a transitional setting dominated by mudstones, coals, and small lenses of sandstones (Late Cretaceous-Middle Paleocene sediments) and in a mixture of deltaic and fluvial conditions (Late Paleocene-Early Eocene sediments). The biostratigraphic control was based on palynological zones for the region. The delta (super 13) C (sub TOM) values for the studied terrestrial sequence show three carbon-isotope excursions, which correlate closely with those present in the marine record. The delta (super 13) C (sub TOM) values decreased from -24.2 ppm to -26.5 ppm in sediments accumulated during Early to Middle Paleocene, increased from -26.5 ppm to -23.8 ppm during the Late Paleocene, and decreased from -23.8 ppm to -26.5 ppm near the Paleocene-Eocene boundary (52-50 Ma). Selected biomarkers indicate that most of the organic matter derived from both gymnosperms and angiosperms. Moreover, the analyses of selected biomarker ratios (CPI, Pr/Ph, P (sub aq) , and beta beta /beta beta +alpha beta hopanes) show some diagenetic transformation in the preserved organic matter. However, no correlation between diagenesis and delta (super 13) C (sub TOM) values was detected, thus suggesting that delta (super 13) C (sub TOM) could be correlated with delta (super 13) C (sub carbonate) values. The close correspondence that was found between delta (super 13) C (sub TOM) and delta (super 13) C (sub carbonate) values (Delta (super 13) C (sub TOM-carbonate) approximately -27 ppm) provides support to the hypothesis that a tight land-plant-oceans linkage exists through geologic timescales via atmospheric carbon dioxide.

Few studies have evaluated the applicability of various paleohydrological models to inverted fluvial systems. The first phase of this investigation focused on an extensive (spanning approximately 12 km) inverted paleochannel system that consists of four sandstone-capped, carbonate-cemented, sinuous ridges within the Early Cretaceous Cedar Mountain Formation located southwest of Green River, Utah. Morphologic and sedimentologic observations of the exhumed paleochannels were used to evaluate multiple numerical models for reconstructing paleofluvial hydrological parameters. Another objective of the study was to determine whether aerial or orbital observations yield model results that are consistent with those constrained by field data. The models yield an envelope of plausible dominant discharge values (100-500 m (super 3) /s), reflecting the limitations of the approach, and no single model can be used to reliably estimate paleodischarge. On Mars, landforms with attributes consistent with inverted channels have been identified. In spite of differences in the formation history between these martian landforms and the terrestrial analog described here, including potential differences in cement composition and the erosional agent that was responsible for relief inversion, these numerical models can be applied (with modification) to the martian landforms and yield an envelope of plausible values for dominant discharge.

The Motagua fault, the central active strand of the suture zone, underwent two major collisional events within a system otherwise dominated by strike-slip motion. The first event is recorded by high-pressure/low temperature (HP/LT) eclogites and related rocks that occur within serpentinites both north and south of the Motagua fault. Lawsonite eclogites south of the fault are not significantly retrograded and give (super 40) Ar/ (super 39) Ar ages of 125-116 Ma and Sm-Nd mineral isochrons of 144-132 Ma. Eclogites north of the fault give similar Sm-Nd isochron ages (131-126 Ma) but otherwise differ in that they are strongly overprinted by a lower pressure assemblage and, along with associated HP/LT rocks, give much younger (super 40) Ar/ (super 39) Ar ages of 88-55 Ma indicating a later amphibolite facies metamorphic event. We propose therefore that all serpentinite hosted eclogites along the Motagua fault formed at essentially the same time in different parts of a laterally extensive Lower Cretaceous forearc subduction system, but subsequently underwent different histories. The southern assemblages were thrust southwards (present coordinates) immediately after HP metamorphism whereas the northern association was retrograded during a later collision that thrust it northward at ca. 70 Ma. They were subsequently juxtaposed opposite each other by major strike slip motion. This model implies that the HP rocks on opposing sides of the Motagua fault evolved along a plate boundary that underwent both dip slip and strike slip motion throughout the Late Cretaceous as a result of oblique convergence. The juxtaposition of a convergent and strike slip system means that HP/LT rocks within serpentinites can be found at depth along much of the modern Guatemala suture zone and its eastward extension into the northern Caribbean. Both sets of assemblages were exhumed relatively recently by the uplift of mountain ranges on both sides of the fault caused by movement along a restraining bend. Recent exhumation explains the apparently lack of offset of surface outcrops along a major strike slip fault.

To date insufficient progress has been made on meeting this target. New efforts to develop a preliminary list beyond using the full IUCN criteria in plant assessments are needed. Here we present an algorithm that provides a preliminary assessment of the conservation status of plant species using data from herbarium specimens. We use Hawaiian specimen data from the United States National Herbarium to calibrate the parameters of the algorithm and then use specimen data from the Arecaceae, Commelinaceae, Gesneriaceae and Heliconiaceae as examples of the application of the algorithm. The algorithm was calibrated to insure 95% accuracy in placing the Hawaiian plant species into previously and independently determined threatened categories. Our results indicate that 28% of the Hawaiian taxa, 27% of the species of Arecaceae, 45% of the species of Commelinaceae, 32% of the species of Gesneriaceae, and 35% of the species of Heliconiaceae are Not Threatened and will not need any further evaluation for the preliminary assessment. Species identified here as Potentially Extinct and Potentially Threatened can be further assessed by additional herbarium material and/or conservation specialists for final evaluation using other assessment strategies (e.g., regional and national lists, taxonomic expert assessment, etc.).

In some cases, phorids live commensally with ants, with the colony offering protection and/or feeding opportunities. In this study we examined the phorid Commoptera solenopsidis in association with a new host species, Pheidole dentata. An ethogram was performed describing the fly and its association with different P. dentata castes. The flies spent most of their time performing grooming behaviors, allogrooming ants, or self-grooming and most commonly were associated with the major workers. We discuss the significance of this association as well as the possible evolutionary driving force behind C. solenopsidis having multiple hosts.

(E.) alba (Horn 1894); L. (E.) albens (Horn 1895); L. (E.) arnoldi (Horn 1904); L. (E.) barbifrons (Boheman 1848); and L. (E.) Somalia (Fairmaire 1882). The taxonomy of this subgenus is reviewed and Lophyra (Eriolophyra) barbifrons marqueza (Peringuey 1896) is placed as a synonym of L. (E.) barbifrons. Information about the ecology of species of Lophyra (Eriolophyra) is summarized: Lophyra (Eriolophyra) alba, L. (E.) albens, and L. (E.) amoldi are associated with sandy riverine areas in southern, central, and west-central Africa, respectively, while L. (E.) barbifrons and L. (E.) Somalia are associated with coastal sand beaches in southern and eastern Africa, respectively. Descriptions of adult foraging, thermoregulatory, reproductive, and defensive behaviors are provided for L. (E.) alba, based on recent observations at sites along the Letaba River in Kruger National Park, South Africa. A hypothesis of phylogenetic relationships is proposed for the five species of the subgenus Eriolophyra on the basis of adult morphological characteristics. Morphological characters suggest that this group forms a monophy-letic clade within the broader complex of species allied to Lophyra.

The Bliss Rapids snail is a federally listed yet poorly known small caenogastropod which lives in the Snake River drainage (main stem river and spring-fed tributaries) of south-central Idaho. The construction of three large dams along this portion of the Snake River during the 20th century is thought to have fragmented a single, ancestral population of this species into genetically isolated subunits that are vulnerable to extinction. We assessed variation of 11 microsatellite loci within and among 29 samples (820 snails) from across the entire range of the Bliss Rapids snail to assess genetic structure and test whether habitat fragmentation resulting from dam construction has impacted population connectivity.2. The overall FST (0.15133, P <0.05) and pairwise comparisons among samples (384-406 significant) indicated extensive population subdivision in general. A consistent trend of isolation by distance trend was not detected by Mantel tests. We found no evidence of reduced genetic diversity attributable to segmentation of the Snake River, and genetic variation among portions of drainage separated by the dams was not significant. Population structuring in spring-tributary habitats was considerably greater than in the main stem river as evidenced by differences in FST (0.18370, 0.06492) and the number of private alleles detected (16, 4), and by the results of an assignment test (69.4%, 58.7% correctly classified to sample of origin) and Bayesian genetic clustering algorithm.3. Our results provide no evidence that dam construction has genetically impacted extant populations of the Bliss Rapids snail. We speculate that the generally weaker genetic structuring of riverine populations of this species is a result of passive dispersal within the water column, which may enable occasional passage through the dams. The somewhat stronger structuring observed in a portion of the river (Shoshone reach) which receives discharge from many springs may be due to local mixing of main stem and more highly differentiated tributary populations. Our findings parallel recent, genetically based studies of other western North American freshwater gastropods that also demonstrate complex population structure that conflicts with traditional concepts of dispersal ability and sensitivity to putative barriers.

We used a chronosequence of nest sites on Barro Colorado Island, Panama, to assess the influence of leaf-cutting ants (Atta colombica) on nutrient availability in a neotropical rainforest. Twelve nest sites were sampled, including active nests, recently abandoned nests (1 year). Waste material discarded by the ants down-slope from the nests contained large concentrations of nitrogen and phosphorus in both total and soluble forms, but decomposed within one year after the nests were abandoned. Despite this, soil under the waste material contained high concentrations of nitrate and ammonium that persisted after the disappearance of the waste, although soluble phosphate returned to background concentrations within one year of nest abandonment. Fine roots were more abundant in soil under waste than control soils up to one year after nest abandonment, but were not significantly different for older sites. In contrast to the waste dumps, soil above the underground nest chambers consistently contained lower nutrient concentrations than control soils, although this was not statistically significant. We conclude that the 'islands of fertility' created by leaf-cutting ants provide a nutritional benefit to nearby plants for less than one year after nest abandonment in the moist tropical environment of Barro Colorado Island.

Our objectives were to 1) observe spatial and temporal changes in total mercury (HgT) and MeHg concentrations in the mid-Atlantic coastal region, 2) investigate biogeochemical factors that affect MeHg production, and 3) examine the potential of these sediments as sources of MeHg to coastal and open waters. Estuarine, shelf and slope sediments contained on average 0.5 to 1.5% Hg as MeHg (% MeHg), which increased significantly with salinity across our study site, with weak seasonal trends. Methylation rate constants (k (sub meth) ), estimated using enriched stable mercury isotope spikes to intact cores, showed a similar, but weaker, salinity trend, but strong seasonality, and was highly correlated with % MeHg. Together, these patterns suggest that some fraction of MeHg is preserved thru seasons, as found by others [Orihel, D. M., Paterson, M. J., Blanchfield, P. J., Bodaly, R. A., Gilmour, C. C., Hintelmann, H., 2008. Temporal changes in the distribution, methylation, and bioaccumulation of newly deposited mercury in an aquatic ecosystem. Environmental Pollution 154, 77] Similar to other ecosystems, methylation was most favored in sediment depth horizons where sulfate was available, but sulfide concentrations were low (between 0.1 and 10 mu M). MeHg production was maximal at the sediment surface in the organic sediments of the upper and mid Bay where oxygen penetration was small, but was found at increasingly deeper depths, and across a wider vertical range, as salinity increased, where oxygen penetration was deeper. Vertical trends in MeHg production mirrored the deeper, vertically expanded redox boundary layers in these offshore sediments. The organic content of the sediments had a strong impact on the sediment:water partitioning of Hg, and therefore, on methylation rates. However, the HgT distribution coefficient (K (sub D) ) normalized to organic matter varied by more than an order of magnitude across the study area, suggesting an important role of organic matter quality in Hg sequestration. We hypothesize that the lower sulfur content organic matter of shelf and slope sediments has a lower binding capacity for Hg resulting in higher MeHg production, relative to sediments in the estuary. Substantially higher MeHg concentrations in pore water relative to the water column indicate all sites are sources of MeHg to the water column throughout the seasons studied. Calculated diffusional fluxes for MeHg averaged nearly equal 1 pmol m (super -2) day (super -1) . It is likely that the total MeHg flux in sediments of the lower Bay and continental margin are significantly higher than their estimated diffusive fluxes due to enhanced MeHg mobilization by biological and/or physical processes. Our flux estimates across the full salinity gradient of Chesapeake Bay and its adjacent slope and shelf strongly suggest that the flux from coastal sediments is of the same order as other sources and contributes substantially to the coastal MeHg budget.

To test directly the response of fish contamination to changing mercury deposition, we are conducting the METAALICUS study, a whole-ecosystem experiment, increasing the mercury load to a lake and its watershed by the addition of enriched stable mercury isotopes. The isotopes allowed us to distinguish between experimentally applied mercury and mercury already present in the ecosystem and to examine bioaccumulation of mercury deposited to different parts of the watershed. Loading began in 2001 and ended in 2007. In this paper we will present mercury and methylmercury budgets for the study lake for the entire 7 year loading period. Overall, we increased the total Hg load to L658 and its watershed by roughly a factor of 3. However, we only increased the Hg load the lake itself by about 2X, since, during the seven years of addition, almost none of the Hg spike deposited to the watershed was transported all the way to the lake. Spike Hg concentrations in lake water rose each year during the open-water loading period and declined rapidly each winter. Methylmercury production in the lake responded rapidly to changes in mercury load during the first year of addition. After about 3 years, the increase in MeHg in lake water and in surface sediments slowed, suggesting that MeHg production was approaching a new level, or different rate, in response to the increased Hg load. We will discuss major input and loss terms for newly deposited Hg, the timing and proportionality of response, the timing and locations of MeHg production within the lake.

A high-grade orthogneiss unit yields U-Pb zircon protolith crystallization ages of approximately 613 Ma. It was metamorphosed and intruded by an Early Ordovician granitoid. Subsequently, two different volcano-sedimentary sequences were laid down and metamorphosed, probably as a consequence of terrane accretion. The older sequence was deposited and metamorphosed between 450 and 420 Ma, and the younger one was deposited after 320 Ma and metamorphosed at 310 Ma. U-Pb detrital zircon age patterns from the two sequences are within the age intervals 315-480, 480-860, 960-1400, and >1400 Ma. These data strongly suggest geological and spatial links between the different units, implying the existence of active magmatism contemporaneous with the reworking of previously formed orogenic complexes. Mesoproterozoic and older ages suggest that the detrital sources are on the western margin of Gondwana, near the Amazonian Craton and/or other Grenvillian-type domains, such as those found within the Andean belt. Neoproterozoic to Ordovician zircons suggest that this crustal segment was formed on an active margin along the western side of the Amazonian Craton. Whole-rock Nd isotope data from metasedimentary rocks of the two younger units yield epsilon (sub Nd(450 Ma, 310Ma)) values between -6.3 and -13.2 and Sm-Nd T (sub DM) model ages between 1.6 and 2.1 Ga. The comparison of the Nd isotope record with the U-Pb detrital zircon data suggests that recycling of older crust was an important factor in the growth of the central Peruvian segment of the proto-Andean margin during the Proterozoic and the Early Paleozoic. Different tectonic and paleogeographic models are discussed in light of the new data presented here.

Eastward migration of the Cenozoic orogenic front has also been inferred from the foreland basin record west of the Eastern Cordillera. However, farther east, limited data provided by foreland basin strata and the adjacent Eastern Cordillera complicate any correlation among mountain building, exhumation, and foreland basin sedimentation. In this study, we present new data from the Medina Basin in the eastern foothills of the Eastern Cordillera of Colombia. We report sedimentological data and palynological ages that link an eastward-thinning early Oligocene to early Miocene syntectonic wedge containing rapid facies changes with an episode of fast tectonic subsidence starting at ca. 31 Ma. This record may represent the first evidence of topographic loading generated by slip along the principal basement-bounding thrusts in the Eastern Cordillera to the southwest of the basin. Zircon fission-track ages and paleocurrent analysis reveal the location of these thrust loads and illustrate a time lag between the sedimentary signal of topographic loading and the timing of exhumation (ca. 18 Ma). This lag may reflect the period between the onset of range uplift and significant removal of overburden. Vitrinite reflectance data document northward along-strike propagation of the deformation front and folding of the Oligocene syntectonic wedge. This deformation was coupled with a nonuniform incorporation of the basin into the wedge-top depozone. Thus, our data set constitutes unique evidence for the early growth and propagation of the deformation front in the Eastern Cordillera, which may also improve our understanding of spatiotemporal patterns of foreland evolution in other mountain belts.

Results generated are precisely correlated to sea-level changes inferred from European sequence stratigraphy using the twin delta (super 13) C excursions mid-Cenomanian event (MCE) Ia and MCE Ib. Microfossils analyzed (surface-dwelling to deep-dwelling planktonic foraminifera, benthic foraminifera, coccoliths) show remarkably consistent intertaxon delta (super 18) O and delta (super 13) C offsets; comparative scanning electron microscope and Sr/Ca analyses allow some delta (super 18) O data to be eliminated because of selective diagenesis. Across MCE Ia, the proposed interval of major glacioeustatic regression, the planktonic delta (super 18) O values are constant for each taxon. The absence of a mean seawater delta (super 18) O shift contradicts predictions for the mid-Cenomanian glaciation episode. The benthic delta (super 18) O records show significant fluctuations during MCE I, implying short-term variability in North Atlantic intermediate-water and deep-water circulation patterns and/or sources at that time.

Our goal was to test which of two possible exchange mechanisms is operative during the reaction: (1) diffusion of cations in and out of the interlayer or (2) dissolution of Na-birnessite and reprecipitation of Cs-birnessite. The appearance of distinct XRD peaks for Na- and Cs-rich phases in partially exchanged samples offered support for a simple diffusion model, but it was inconsistent with the compositional and crystallographic homogeneity of (Na,Cs)-birnessite platelets from core to rim as ascertained by TEM. Time-resolved XRD revealed systematic changes in the structure of the emergent Cs-rich birnessite phase during exchange, in conflict with a dissolution and reprecipitation model. Instead, we propose that exchange occurred by sequential delamination of Mn oxide octahedral sheets. Exfoliation of a given interlayer region allowed for wholesale replacement of Na by Cs and was rapidly followed by reassembly. This model accounts for the rapidity of metal exchange in birnessite, the co-existence of distinct Na- and Cs-birnessite phases during the process of exchange, and the uniformly mixed Na- and Cs-compositions ascertained from point analyses by selected area electron diffraction and energy dispersive spectroscopy of partially exchanged grains.

Based on distinctive morphologies and damage patterns of elongate, ovoid, lens-, or teardrop-shaped scars in the leaves, we assign this insect damage to the ichnogenus Paleoovoidus, consisting of an existing ichnospecies, P. rectus, and two new ichnospecies, P. arcuatum and P. bifurcatus. In P. rectus, the scars are characteristically arranged in linear rows along the midvein; in P. bifurcatus, scars are distributed in double rows along the midvein and parallel to secondary veins; and in P. arcuatum, scars are deployed in rectilinear and arcuate rows. In some cases, the narrow, angulate end of individual scars bear a darkened region encompassing a circular hole or similar feature indicating ovipositor tissue penetration. A comparison to the structure and surface pattern of modern ovipositional damage on dicotyledonous leaves suggests considerable similarity to certain zygopteran Odonata. Specifically, members of the Lestidae probably produced P. rectus and P. bifurcatus, whereas species of Coenagrionidae were responsible for P. arcuatum. Both Patagonian localities represent an elevated diversity of potential fern, gymnosperm, and especially angiosperm hosts, the targets of all observed oviposition. However, we did not detect targeting of particular plant families. Our results indicate behavioral stasis for the three ovipositional patterns for at least 50 million years. Nevertheless, synonymy of these oviposition patterns with mid-Mesozoic ichnospecies indicates older origins for these distinctive modes of oviposition.

The Rembrandt basin is comparable in age to the Caloris basin, is partially flooded by volcanic plains, and displays a unique wheel-and-spoke-like pattern of basin-radial and basin-concentric wrinkle ridges and graben. Stratigraphic relations indicate a multistaged infilling and deformational history involving successive or overlapping phases of contractional and extensional deformation. The youngest deformation of the basin involved the formation of a approximately 1000-kilometer-long lobate scarp, a product of the global cooling and contraction of Mercury.

Impact-related stratigraphy is preserved in the crater walls, and meteoritic debris is present near the crater rim. The size of hematite-rich concretions decreases up-section, documenting variation in the intensity of groundwater processes. Layering in the crater walls preserves evidence of ancient wind-blown dunes. Compositional variations with depth mimic those approximately 6 kilometers to the north and demonstrate that water-induced alteration at Meridiani Planum was regional in scope.

Together, MESSENGER and Mariner 10 observations of Mercury now provide a near-global look at the planet, revealing lateral and vertical heterogeneities in the color and thus composition of Mercury's crust. Smooth plains cover approximately 40% of the surface, and evidence for the volcanic origin of large expanses of plains suggests that a substantial portion of the crust originated volcanically. A low-reflectance, relatively blue component affects at least 15% of the surface and is concentrated in crater and basin ejecta. Its spectral characteristics and likely origin at depth are consistent with its apparent excavation from a lower crust or upper mantle enriched in iron- and titanium-bearing oxides.

We find that W partitioning is extremely sensitive to the carbon content of the metal alloy, becoming about an order of magnitude more siderophile at carbon saturation. Activity-composition corrections based on interactions between W-C and Fe-C in metal solution shift calculated D(W) to more lithophile values, and calculated oxygen fugacities (fO (sub 2) ) to more oxidizing values, than uncorrected data. W exists as a highly charged cation in silicate solution, displaying a mixture of oxidation states from +4 to +6 in experiments at fO (sub 2) of approximately 0.5-2 log units below the iron-wustite buffer. At constant fO (sub 2) , the average calculated valence decreases with pressure from approximately +5.5 at 0.5 GPa to approximately +4 at 11-18 GPa. As a result of its high oxidation state, W partitioning is strongly dependent on silicate melt polymerization and fO (sub 2) . In contrast to some previous results, we find that D(W) may decrease slightly in response to increasing temperature in the pressure range of our experiments. Pressure exerts a non-monotonic effect: D(W) increases with pressure up to approximately 3 to 4 GPa, but decreases at higher pressures. Previous models for the effects of pressure and temperature on W partitioning that conflict with our results appear to result from a conflation of the intensive parameters of pressure, temperature, and carbon content. The mantle abundance of W could have been set by single-stage metal-silicate equilibration along the liquidus in a deep peridotite magma ocean at pressures from 20-50 GPa, and at oxygen fugacities consistent with the mantle's present iron budget (IW-2 to -2.5). Equilibration at higher pressure is viable if the core-forming metal contained a significant, but not unreasonable, abundance of carbon ( approximately 2 wt.%). Recent continuous accretion models involving multi-stage metal-silicate equilibration in a deepening magma ocean with progressive oxidation of the silicate remain permissible given our new treatment of W partitioning data.

The first set examined the effect of P on solid metal/liquid metal partitioning behavior of 22 elements, while the other set explored the effect of the crystal structures of body-centered cubic (alpha )- and face-centered cubic (gamma )-solid Fe alloys on partitioning behavior. Overall, the effect of P on the partition coefficients for the majority of the elements was minimal. As, Au, Ga, Ge, Ir, Os, Pt, Re, and Sb showed slightly increasing partition coefficients with increasing P-content of the metallic liquid. Co, Cu, Pd, and Sn showed constant partition coefficients. Rh, Ru, W, and Mo showed phosphorophile (P-loving) tendencies. Parameterization models were applied to solid metal/liquid metal results for 12 elements. As, Au, Pt, and Re failed to match previous parameterization models, requiring the determination of separate parameters for the Fe-Ni-S and Fe-Ni-P systems. Experiments with coexisting alpha and gamma Fe alloy solids produced partitioning ratios close to unity, indicating that an alpha versus gamma Fe alloy crystal structure has only a minor influence on the partitioning behaviors of the trace element studied. A simple relationship between an element's natural crystal structure and its alpha /gamma partitioning ratio was not observed. If an iron meteorite crystallizes from a single metallic liquid that contains both S and P, the effect of P on the distribution of elements between the crystallizing solids and the residual liquid will be minor in comparison to the effect of S. This indicates that to a first order, fractional crystallization models of the Fe-Ni-S-P system that do not take into account P are appropriate for interpreting the evolution of iron meteorites if the effects of S are appropriately included in the effort.

Observations of Home Plate from orbit and from the summit of Husband Hill reveal clear differences in visible/near-infrared (VNIR) colors between its eastern and western regions that are consistent with mineralogical compositions indicated by Mossbauer spectrometer (MB) and by Miniature Thermal Emission Spectrometer (Mini-TES). Pyroxene and magnetite dominate the east side, while olivine, nanophase Fe oxide (npOx) and glass are more abundant on the western side. Alpha Particle X-Ray Spectrometer (APXS) observations reveal that eastern Home Plate has higher Si/Mg, Al, Zn, Ni, and K, while Cl and Br are higher in the west. We propose that these variations are the result of two distinct alteration regimes that may or may not be temporally related: a localized, higher temperature recrystallization and alteration of the east side of Home Plate and lower temperature alteration of the western side that produced npOx.

Lyngbya spp. are prolific producers of biologically active compounds that deter grazers and help blooms persist in the marine environment. Here, our investigations reveal the presence of three distinct Lyngbya species on nearshore reefs in Broward County, FL, sampled in 2006 and 2007. With a combination of morphological measurements, molecular biology techniques, and natural products chemistry, we associated these three Lyngbya species with three distinct Lyngbya chemotypes. One species, identified as Lyngbya cf. confervoides via morphological measurements and 16S rRNA gene sequencing, produces a diverse array of bioactive peptides and depsipeptides. Our results indicate that the other two Lyngbya species produce either microcolins A and B or curacin D and dragonamides C and D. Results from screening for the biosynthetic capacity for curacin production among the three Lyngbya chemotypes in this study correlated that capacity with the presence of curacin D. Our work on these bloom-forming Lyngbya species emphasizes the significant phylogenetic and chemical diversity of the marine cyanobacteria on southern Florida reefs and identifies some of the genetic components of those differences.

This study evaluates the experiences of farmers participating in a native species reforestation initiative in rural Panama to identify lessons learned that can guide on-going or future tree planting efforts. Based on the results of a questionnaire administered to program participants and non-participants (n=68), we found that trees are important to farmers for multiple reasons, primary a variety of environmental and economic benefits. No relationship between the size of landholdings or land tenure status and the desire to plant trees was found. All participants in the program considered their experience to be positive, few had problems with their plantations, and most were interested in planting more native trees. The program's frequent and ongoing technical support was an important factor for farmers. These results indicate widespread interest in, and success with, planting native species and underscore the need to systematically examine farmers' interests and perceptions when planning, implementing, and evaluating reforestation initiatives.

The areas predicted suitable for the Hyrcanus Group species were the most extensive for Anopheles sinensis Wiedemann, An. kleini Rueda, An. belenrae Rueda, and An. pullus Yamada, intermediate for An. sineroides Yamada, and the most restricted for An. lesteri Baisas and Hu and the non-Hyrcanus Group species An. koreicus Yamada and Watanabe and An. lindesayi Yamada. The relative vectorial importance of these species is unknown, and all, except An. koreicus and An. lindesayi, are predicted to occur widely in the northwest of the ROK where malaria transmission has been sporadic since its resurgence in 1993. Our ENMs suggest that it is unlikely that An. koreicus and An. lindesayi are vectors, but we do not document consistent geographic differentiation that might incriminate any of the other species as vectors. Because all species are predicted to occur in North Korea, we also cannot reject the hypothesis that malaria infected mosquitoes from North Korea may have been the cause of the resurgence of malaria in the ROK. Ecological differentiation of the eight species is inferred from collection locations and 34 environmental layers based on remote sensing and global climatic averages. Interspecific differences were noted, and characterizing mosquito habitats by ground-based and remote sensing methods is proposed.

However, these distinctions are often subjective and can be variable within a species. Geometric morphometrics were used to quantitatively assess shape variation of the second gnathopod propodus of three species of caprellids in North America, including the non-native Caprella mutica. Gnathopod shapes of C. mutica specimens from different latitudes revealed distinct morphologies; the factors responsible for the shape variations are unknown. Allometric change of propodus shape was observed in C. mutica. Larger individuals showed a wide array of possible propodus morphologies. Despite this variability, there were clear differences between large specimens of C. mutica and two species native to North America: C. alaskana and C. kennerlyi. The use of geometric morphometrics and the thin-plate spline method can serve to both complement descriptions using traditional keys and aid in identification of non-native species in novel geographical regions.

Singletons are larger than other species, not gender-biased, share no particular lifestyle, and are not clumped at 0.25-1 ha scales.4.Monte Carlo simulation of the best-fit lognormal community shows that the observed data fit a random sample from a community of ~700 species and 1-2 million individuals, implying approximately 4% true singleton frequency.5.Undersampling causes systematic negative bias of species richness, and should be the default null hypothesis for singleton frequencies.6.Drastically greater sampling intensity in tropical arthropod inventory studies is required to yield realistic species richness estimates.7.The lognormal distribution deserves greater consideration as a richness estimator when undersampling bias is severe.

Most fishes living there have pelagic larvae using the rich waters of the upper 200?m. Morphological and behavioural specializations necessary to occupy such contrasting environments have resulted in remarkable developmental changes and life-history strategies. We resolve a long-standing biological and taxonomic conundrum by documenting the most extreme example of ontogenetic metamorphoses and sexual dimorphism in vertebrates. Based on morphology and mitogenomic sequence data, we show that fishes currently assigned to three families with greatly differing morphologies, Mirapinnidae (tapetails), Megalomycteridae (bignose fishes) and Cetomimidae (whalefishes), are larvae, males and females, respectively, of a single family Cetomimidae. Morphological transformations involve dramatic changes in the skeleton, most spectacularly in the head, and are correlated with distinctly different feeding mechanisms. Larvae have small, upturned mouths and gorge on copepods. Females have huge gapes with long, horizontal jaws and specialized gill arches allowing them to capture larger prey. Males cease feeding, lose their stomach and oesophagus, and apparently convert the energy from the bolus of copepods found in all transforming males to a massive liver that supports them throughout adult life.

A prediction of this theory is the convergent evolution of traits in lineages experiencing similar environments. The Hawaiian honeycreepers are a spectacular example of adaptive radiation and may demonstrate convergence, but uncertainty about phylogenetic relationships within the group has made it difficult to assess such evolutionary patterns. We examine the phylogenetic relationships of the Hawaii creeper (Oreomystis mana), a bird that in a suite of morphological, ecological and behavioural traits closely resembles the Kauai creeper (Oreomystis bairdi), but whose mitochondrial DNA (mtDNA) and osteology suggest a relationship with the amakihis (Hemignathus in part) and akepas (Loxops). We analysed nuclear DNA sequence data from 11 relevant honeycreeper taxa and one outgroup to test whether the character contradiction results from historical hybridization and mtDNA introgression, or convergent evolution. We found no evidence of past hybridization, a phenomenon that remains undocumented in Hawaiian honeycreepers, and confirmed mtDNA and osteological evidence that the Hawaii creeper is most closely related to the amakihis and akepas. Thus, the morphological, ecological and behavioural similarities between the evolutionarily distant Hawaii and Kauai creepers represent an extreme example of convergent evolution and demonstrate how natural selection can lead to repeatable evolutionary outcomes.

AN - 1270038898; 2013-009803 AB - Although geneticists and archaeologists continue to make progress world-wide in documenting the time and place of the initial domestication of a growing number of plants and animals, far less is known regarding the critically important context of coalescence of various species into distinctive sets or complexes of domesticates in each of the world's 10 or more independent centers of agricultural origin. In this article, the initial emergence of a crop complex is described for one of the best-documented of these independent centers, eastern North America (ENA). Before 4000 B.P. there is no indication of a crop complex in ENA, only isolated evidence for single indigenous domesticate species. By 3800 B.P., however, at least 5 domesticated seed-bearing plants formed a coherent complex in the river valley corridors of ENA. Accelerator mass spectrometer radiocarbon dates and reanalysis of archaeobotanical assemblages from a short occupation of the Riverton Site in Illinois documents the contemporary cultivation at 3800 B.P. of domesticated bottle gourd (Lagenaria siceraria), marshelder (Iva annua var. macrocarpa), sunflower (Helianthus annuus var. macrocarpus), and 2 cultivated varieties of chenopod (Chenopodium berlandieri), as well as the possible cultivation of Cucurbita pepo squash and little barley (Hordeum pusillum). Rather than marking either an abrupt developmental break or a necessary response to population-packing or compressed resource catchments, the coalescence of an initial crop complex in ENA appears to reflect an integrated expansion and enhancement of preexisting hunting and gathering economies that took place within a context of stable long-term adaptation to resource-rich river valley settings.

The maximal rate of SLR that these ecosystems can tolerate depends partly on mineral sediment deposition, but the accumulation of organic matter is equally important for many wetlands. Plant productivity drives organic matter dynamics and is sensitive to global change factors, such as rising atmospheric CO (sub 2) concentration. It remains unknown how global change will influence organic mechanisms that determine future tidal wetland viability. Here, we present experimental evidence that plant response to elevated atmospheric [CO (sub 2) ] stimulates biogenic mechanisms of elevation gain in a brackish marsh. Elevated CO (sub 2) (ambient + 340 ppm) accelerated soil elevation gain by 3.9 mm yr (super -1) in this 2-year field study, an effect mediated by stimulation of below-ground plant productivity. Further, a companion greenhouse experiment revealed that the CO (sub 2) effect was enhanced under salinity and flooding conditions likely to accompany future SLR. Our results indicate that by stimulating biogenic contributions to marsh elevation, increases in the greenhouse gas, CO (sub 2) , may paradoxically aid some coastal wetlands in counterbalancing rising seas.

Using hierarchical clustering refined by Analysis of Similarity (ANOSIM), we determined geographic groupings in the distributions of the entire fauna, of regional endemics and of 3 functional (habitat) groups of species. We also examined the distributions of local endemics throughout the TEP and how differences in faunal size versus faunal composition among sites contribute to the subdivision pattern. Our results indicate that: (1) the continental coast contains 2 provinces, the Cortez (Gulf of California and lower Pacific Baja) and the Panamic (southward), each of which has a peak in abundance of local endemics and of overall species richness; (2) the northern and southern boundaries of the TEP are located near Magdalena Bay on Baja California (~25N) and the southern shore of the Gulf of Guayaquil (~4S), respectively; and (3) the 5 oceanic islands/archipelagos collectively represent a third, Ocean Island Province. Relative to mainland areas, the fauna of the ocean islands is smaller, has a different functional-group composition, and includes more transpacific species and more highly localized endemics. The 3-province pattern probably developed in response to the formation of the Gulf of California, the rise of the Isthmus of Panama, immigration from the north, south and west to the TEP, and differing environmental conditions between and within provinces. In contrast, barriers to dispersal within this geographically simple region are weak and likely had much less influence.

Likely dating from between the second half of the ninth and the first half of the fourteenth centuries, these bricks contain the oldest graphic representations of Sumatra architecture. While two of these designs have been previously published, the brick images have not been thoroughly analyzed in order to determine what new light they shed on the domestic architecture and building traditions of early lowland Sumatran settlements. To address this lacuna, we analyze the bricks and their archaeological context in order to interpret when the images were made, who created the images, the purpose behind them, the types of architecture depicted on the bricks, and the reasons behind the diversity of building types represented. Having argued that the majority of bricks shows domestic architecture reflecting a variety of cultural influences, we conclude by suggesting that the presence of such images supports the scholarly view that Muara Jambi was a multi-ethnic trading community.

Recent fieldwork discovered a well-preserved molluscan assemblage that occurs near the top of the Carbonera Formation (lower Miocene) in the central foothills of the Eastern Cordillera. This level, named the Huesser horizon, is laterally extensive and can be followed for tens of kilometers. The horizon is 10 m thick and was divided into eight levels, five of them highly fossiliferous. Most of the levels are dominated by the freshwater gastropod Sheppardiconcha, with lower abundances of the bivalves Anodondites and Mytilopsis. The top level is dominated by specimens from the bivalve family Arcidae. The taxonomic composition of the assemblage is similar to that of the Magdalena and Amazonas Basins during the early-to-middle Miocene. Paleoecologic, taphonomic, and palynological analyses indicate that the Huesser accumulated in a freshwater lake system, capped by a marine incursion. The development of a large lake and the subsequent marine event could be related to increasing subsidence coincident with eustatic sea-level rise that has been identified for the basin during the early Miocene.

Eve uku ('hand head') lie within a continuum of things (names, relations, totemic ancestral spirit-beings and sites in the environment) through which ancestral actions are shown to have happened, and descent groups' identities manifest. However, given the ambiguous status of the traditional past among the I'ai, the power of these forms is circumscribed to the village thus making them ineffectual tokens in the bid to secure royalties from resource extraction. Instead, highly coveted documents known as ILG certificates have emerged as efficacious things by which royalties can be secured. Examining these certificates as objects, I investigate how these documents help materialise anew descent groups, communities' relations to their environment and thus their aspirations for development with its attending materialities. The problem for the I'ai, however, remains how to obtain these documents and, as with eve uku, how to control them.

In the introduction to this collection of essays, we examine the role of the ethnography of Oceania in the development of our anthropological perspectives on materialisation, the dynamic process by which persons and things are inter-related. Building upon the recent resurgence of theoretical interests in things we use the term materialisation (rather than material culture or materiality) to capture the vitality of the lived processes by which ideas of objectivity and subjectivity, persons and things, minds and bodies are entangled. Taking a processual view, we advocate for an Oceanic anthropology that continues to engage with things on the ground; that asks what strategies communities use to materialise their social relations, desires and values; and that recognises how these processes remain important tools for understanding historical and contemporary Oceanic societies. Examining these locally articulated processes and forms contributes to a material (re)turn for anthropology that clarifies how we, as scholars, think about things more widely.

However, most deforestation research focuses on tropical rain forests. We analyzed spatial and temporal changes in land cover from 1972 through 2005 at Chatthin Wildlife Sanctuary (CWS), a tropical dry forest in Myanmar (Burma). CWS is one of the largest protected patches of tropical dry forest in Southeast Asia and supports over half the remaining wild population of the endangered Eld's deer. Between 1973 and 2005, 62% of forest was lost at an annual rate of 1.86% in the area, while forest loss inside CWS was only 16% (0.45% annually). Based on trends found during our study period, dry forests outside CWS would not persist beyond 2019, while forests inside CWS would persist for at least another 100years. Analysis of temporal deforestation patterns indicates the highest rate of loss occurred between 1992 and 2001. Conversion to agriculture, shifting agriculture, and flooding from a hydro-electric development were the main deforestation drivers. Fragmentation was also severe, halving the area of suitable Eld's deer habitat between 1973 and 2001, and increasing its isolation. CWS protection efforts were effective in reducing deforestation rates, although deforestation effects extended up to 2km into the sanctuary. Establishing new protected areas for dry forests and finding ways to mitigate human impacts on existing forests are both needed to protect remaining dry forests and the species they support.

Cuvier, 1825. Recent molecular phylogenetic studies suggest that the traditionally recognized genera MarmotaBlumenbach, 1779 (marmots), CynomysRafinesque, 1817 (prairie dogs), and AmmospermophilusMerriam, 1892 (antelope ground squirrels) render Spermophilusparaphyletic, potentially suggesting that multiple generic-level lineages should be credited within Spermophilus. Herein, we recognize 8 genera formerly subsumed in Spermophilus, each of which is morphologically diagnosable, craniometrically distinctive, and recovered as a monophyletic clade in phylogenetic analyses utilizing the mitochondrial gene cytochrome b. Generic-level names are available for each of these ground squirrel assemblages, most of which are exclusively or predominantly North American in distribution (NotocitellusA. H. Howell, 1938; OtospermophilusBrandt, 1844; CallospermophilusMerriam, 1897; IctidomysJ. A. Allen, 1877; PoliocitellusA. H. Howell, 1938; XerospermophilusMerriam, 1892; and UrocitellusObolenskij, 1927). Only Spermophilus sensu stricto is restricted to Eurasia.

Aposematic species were found on nine of the ten active plant species, but on only four of the ten inactive plant species. Norvaposematic insects did not show a significant difference in their association with active versus inactive plants. Our results suggest that the presence of aposematic, herbivorous insects can be used to facilitate the identification of plants with compounds active against important human diseases.

Hypoxia occurred in both years and was associated with a decrease in biomass and a shift in community structure toward opportunistic species in both rivers. Long-term data indicate that the frequency of hypoxia in the York has increased over the last 22 years. In previous work from 620 years ago, the macrobenthic community structure did not change in response to hypoxia in the York; however, in the present study hypoxia was associated with a reduction in community biomass and a change in community structure. We conclude that currently hypoxia is a more important environmental problem in the York than in previous years. Hypoxia likely negatively affects the estuarine food web, as lower macrobenthic biomass could decrease food availability to epibenthic predators.

Headquartered at the Smithsonian Institution Libraries, the Biodiversity Heritage Library (BHL) is one of the cornerstones of the Encyclopedia of Life, a global effort to document all 1.8 million named species of animals, plants, and other forms of life on earth. This paper provides an overview of the BHL and its potential impact on biodiversity research, describes the BHL portal and its innovative search services, and provides a case study of the process from one of the members: the Museum of Comparative Zoology at Harvard University.

AN - 50470923; 2009-032351 AB - A catastrophically buried stand of calamitean sphenopsids and sigillarian lycopsids is reported from the Middle Pennsylvanian of southwestern Indiana, in the Illinois Basin. The plants were exposed in the highwall of a small surface mine and were rooted in a thin bed of coal (peat), thus representing a flooded and buried swamp surface. Coarse, floodborne silts and sands buried the forest to a depth of 250 linear meters of exposed highwall surface, the vegetation appears to have been a patchwork of calamitean thickets, with stems perhaps as tall as 3-5 m, within which scattered, but much larger, emergent Sigillaria trees grew, possibly reaching heights of 10-15 m. No ground cover was observed, nor were foliage or reproductive organs attributable to the dominant plants found. The growth of this vegetation in a peat-forming swamp indicates conditions of high water availability, likely in a humid, high-rainfall climate. This kind of plant assemblage, however, cannot be characterized as a rain forest, given that it consisted of medium-height thickets of horsetails with scattered, emergent, and polelike, giant lycopsids, thus lacking a closed upper canopy and possibly only partially shading the ground.

The differences are so great as to merit a new genus, Oscaravis, for the species. Some osteological characters of Oscaravis suggest that it was less derived than Teratornis and possibly more similar to Argentavis. As the only insular member of the Teratornithidae, Oscaravis shows that teratorns were capable of overwater dispersal, so that the expansion of the family into North America from the south need not have been dependent on the presence of a land bridge.

We report here on archaeological investigations in a region of the central Balsas located near the Iguala Valley in Guerrero State that show for the first time a long sequence of human occupation and plant exploitation reaching back to the early Holocene. One of the sites excavated, the Xihuatoxtla Shelter, contains well-stratified deposits and a stone tool assemblage of bifacially flaked points, simple flake tools, and numerous handstones and milling stone bases radiocarbon dated to at least 8700 calendrical years B.P. As reported in a companion paper (Piperno DR, et al., in this issue of PNAS), starch grain and phytolith residues from the ground and chipped stone tools, plus phytoliths from directly associated sediments, provide evidence for maize (Zea mays L.) and domesticated squash (Cucurbita spp.) in contexts contemporaneous with and stratigraphically below the 8700 calendrical years B.P. date. The radiocarbon determinations, stratigraphic integrity of Xihuatoxtla's deposits, and characteristics of the stone tool assemblages associated with the maize and squash remains all indicate that these plants were early Holocene domesticates. Early agriculture in this region of Mexico appears to have involved small groups of cultivators who were shifting their settlements seasonally and engaging in a variety of subsistence pursuits.

We report starch grain and phytolith data from the Xihuatoxtla Shelter, located in the central Balsas valley, that indicate that maize was present by 8,700 calendrical years ago (cal. B.P.). Phytolith data also indicate an early preceramic presence of a domesticated species of squash, possibly Cucurbita argyrosperma. The starch and phytolith data also allow an evaluation of current hypotheses about how early maize was used, and provide evidence as to the tempo and timing of human selection pressure on 2 major domestication genes in Zea and Cucurbita. Our data confirm an early Holocene chronology for maize domestication that has been previously indicated by archaeological and paleoecological phytolith, starch grain, and pollen data from south of Mexico, and reshift the focus back to an origin in the seasonal tropical forest rather than in the semiarid highlands.

He had already endured tropical diseases in Liberia off and on for more than a decade, and he'd seen his first two wives languish and die there, probably of malaria.

Archaeologists working within this paradigm see macroevolutionary theory as an effective response to the shortcomings of neo-Darwinian biological evolution for studying cultural evolution. Rather than operating at the level of individual traits, macroevolutionary archaeologists emphasize the role of hierarchical processes in culture change. While neo-Darwinian archaeologists disavow any element of human intent in culture change, to macroevolutionary archaeologists human agency is a key component of cultural evolution that allows cultures to respond to pressures more quickly and with greater degree of flexibility and directedness than found in biological evolution. Major culture change, when it happens, is likely to be rapid, even revolutionary, with periods of rapid change separated by periods of relative stasis of actively maintained stability. The emergence of Neolithic cultures has long been recognized as one of two periods of major revolutionary culture change in human prehistory. Here I examine the record for the Near East, tracing the empirical record for the origin of agriculture in this region, as well as other demographic, social, and ideological components of Neolithic emergence. While the empirical record from the Near East subscribes in a general way to basic principles of macroevolutionary theory, cultural evolution cannot be understood through appeal to principles of biological evolution alone, whether based in macroevolutionary theory or neo-Darwinianism. Instead, the key role of human agency in culture change distinguishes cultural evolution from biological evolution and requires a more pluralistic and less doctrinaire appeal to multiple models of change based in both the biological and social sciences.

A topographic map of the tidally flooded area of the island was made and related to the tide-induced water levels. The flooded area approximately doubled during the usual tidal event. The bottom topography is highly irregular with a maximum channel water depth of about 1.5 m, but much of the flooded area experiences a water depth of less than 0.5 m. Water elevations were recorded by automatic water level loggers for periods of time up to 9 months. The usual symmetrical parabolic tide signal was transformed into a highly asymmetrical form as it moved landward through the tangled root system of the red mangrove forest. A normal tide range of 13 cm at the island margin attenuated to 3 cm at a distance of 200 m landward, with a lag time of 2 h for highs and 6 h for lows. Maximum flow velocities of 5 cm/s were measured in the main channels with marked reduction in regions of dense mangrove root and shallow water depth. The combined frictional resistance of the bottom and associated mangrove roots is characterized by a Manning's roughness coefficient, n, that ranged from 0.084 to 0.445. The changing flow pattern within the flooded mangrove swamp was mapped during a 7 h high-to-low tide period using aerial photography to track the movement of slugs of visible dye placed at three locations. Analysis of the sequential time-related photos showed limited lateral dispersion in the tortuous main channel but strong tidally controlled flow direction changes and dispersion along the channel axis. A strong circulatory pattern is observed in a shallow pond at the south central terminus of the tidally affected flow system. This large shallow pond is sparsely populated by dwarf red mangrove and is some 350 m from a primary connection with the surrounding lagoon. Poor flushing of the pond creates water temperatures ranging from 25C in the winter to 40C in the summer. High surface water evaporation creates a hypersaline condition of 45 ppt salinity in summer. In winter, with the infusion of fresh rainwater, salinity of surface water in the pond can be less than 5 ppt. Because of its role in the transport of nutrients and detritus, and its flushing action, the dynamic hydrological system of the mangrove island is a highly important ecological feature of the overwashed mangrove island.

In temperate marine systems, invasions are occurring at a rapid pace, driven by the transfer of organisms by vessels and live trade (including aquaculture and fisheries activities). In contrast, little is known about patterns and processes of tropical marine invasions, although the same species transfer mechanisms are in operation. This disparity may be the result of limited studies of invasions in the tropics relative to temperate regions. Alternatively, the tropics may be less susceptible to invasion than temperate regions for reasons of environmental unsuitability and biotic interactions. This paper provides a brief summary of the current but limited information of marine invasions across latitudes, focusing particular attention on the eastern Pacific north of the Equator. Within this latitudinal framework, the Panama Canal provides an especially important model system for testing predictions about marine invasions in the tropics for reasons of (a) the high level of shipping traffic since the Canal opened in 1914; (b) the permeability of the Canal as a conduit for marine invaders, despite the apparent freshwater barrier; and (c) the current expansion of the Canal that is expected to increase the size and number of ships visiting the region.

The masculinization of females, including the aberrant growth of a penis and vas deferens and occlusion of the capsule gland, has been reported primarily in neogastropods and is particularly well documented in muricids. Compared to temperate areas, few studies of imposex have been undertaken in the tropics, and there are few studies in general on non-neogastropods. Here we report a high frequency of imposex near the Pacific mouth of the Panama Canal in two species of muricids and two species of calyptraeids. The frequency of imposex declined rapidly with distance away from the canal, and several species appeared to be mostly normal less than 10 km from the entrance. This is the first report of imposex in Acanthais brevidentata, Thaisella kiosquiformis, Bostrycapulus calyptraeformis, Crepidula cf. nivea, and Anachis fluctuata. Because imposex has not previously been reported for the Calyptraeidae, a family of protandrous gastropods, a laboratory study was conducted to verify that imposex was not simply retention of the penis after sex change. The 2007 ratification of the International Maritime Organization's convention on antifouling systems should reduce the levels of TBT worldwide, but the persistence of this compound in sediments suggests that imposex may continue to be a problem at the mouth of the canal as routine dredging and large tides frequently resuspend sediment.

We sampled the Rhode River, a subestuary of Chesapeake Bay, during 2004 and 2005 to quantify the abundances of M. leidyi, its scyphomedusan predators, and its mesozooplankton prey, and conducted ctenophore egg production experiments in 2004. Despite low mesozooplankton densities, ctenophores produced up to 9,380 eggs individual super(-1) day super(-1). Temporal patterns, as well as peak abundances, of copepods, ctenophores, and sea nettles (Chrysaora quinquecirrha; the major predator of M. leidyi) varied considerably between years. This interannual variation may have been caused by direct and indirect effects of physical factors, especially low salinities during 2004, on all components of the food web. In 2004, zooplankton abundances peaked in June, M. leidyi abundances steadily increased throughout the summer, and C. quinquecirrha was rare. In contrast, during 2005, C. quinquecirrha density increased during midsummer. As this medusa increased in abundance, M. leidyi numbers declined and copepod abundances increased. Shallow systems with salinities near the minimum threshold for C. quinquecirrha ephyra production may exhibit more extreme interannual variability than deeper, higher-salinity systems and may serve as models to provide insight into factors controlling gelatinous zooplankton dynamics.

It spreads by clonal growth, occurs in a wide range of habitats, and at times forms monotypic stands. Sites that are permanently flooded or are flooded regularly by tides and salt pans are the only mangrove habitats in which B. maritima does not occur or occurs as a few scattered plants. On mangrove-dominated islands in Belize, the coverage and height of B. maritima were highest in open habitats, including sites disturbed by human activities. In a mangrove-dominated mosquito impoundment in Florida, B. maritima occurred in all habitats sampled and, similar to observations in Belize, coverage and height were greatest in the most open habitats. The abundance and, at times, dominance of B. maritima suggests that it may play an important role in the dynamics of mangrove ecosystems, especially in the recruitment and establishment of mangrove seedlings. Mangrove seedlings and saplings were present in most of the plots that were sampled in Belize and Florida, but there was no relationship between the percent cover of B. maritima and the density of seedlings and saplings.

Local fishers and natives attempt to avoid CFP by applying traditional knowledge concerning where and when certain fish species are likely to be ciguatoxic, but this knowledge is incomplete. Evidence gathered over the past decades indicates that CFP events are increasing and becoming more unpredictable, thereby posing a greater threat to local inhabitants as well as tourists. The current understanding of CFP distribution is from studies nearly a decade old and generated largely by self-reported CFP incidents to a call-in "hotline" in Miami, Florida. To better guide resource allocation and focus future research, an active survey method was used to uniformly query public health professionals and fisheries officials on the occurrence of CFP. Points of contact from each of these two groups were compiled for the 24 Caribbean island countries and territories and 9 mainland countries bordering the Caribbean. An outcome of this project will be to provide public health agencies, resource managers, and others with information they can use in developing CFP tracking systems and effective public education programs. The long-term goal of associated efforts is to provide accurate and affordable monitoring tools for predicting the onset of CFP events.

Large collections have been assembled, and new species have been discovered. The effort has included photographic documentation of coloration, yielding characters of value in identification of problematic tropical taxa. Measurements of diversity have been markedly enhanced by extraction corer (yabby pump) sampling in shallow subtidal sediments, especially at Twin Cays. This technique revealed species, genera, and families of thalassinidean decapods not previously known from the region. Studies continue on the ecological roles of these burrowers, dominant bioturbators in seagrass beds where they produce conspicuous mounds of sediment and constitute a major infaunal biomass at Twin Cays. By contrast, familiar large reptant decapods typically dominate shallow rocky substrates. Within the past four years, however, the nonindigenous portunid crab Charybdis hellerii has extensively invaded large portions of hard substrates at Twin Cays. In 2007, it was found to dominate cavities under coral heads in survey areas along the northeastern and southwestern shorelines, possibly displacing populations of large Mithrax, Menippe, Callinectes, and Panulirus previously found there in abundance.

Several groups of plants and sessile invertebrates flourish on the submerged prop roots of red mangrove (Rhizophom mangle), competing for space and tolerating a stressful range of ecological variables (temperature, salinity, nutrients, sedimentation) that is quite different from the more stable climate on nearby coral reefs. To test the limits of tolerance, we monitored populations of these organisms, the abundant sponges in particular, at environmentally and geographically dissimilar locations in Panama and Belize. We used relative abundance estimates and frequency counts of major ecologically functional groups and common sponge species to establish baselines, and we repeated our surveys over long time spans (months to years) to find correlations between community and environmental changes. Both study locations demonstrated environmental quality decline during the time of observation, mainly through mangrove clear-cutting, followed by increase of suspended fine sediments from dredging reef sands and filling in intertidal land, and elevation of nutrient levels from terrestrial inputs. Although our methods are still in a stage of refinement, our data are leading the way to responsible monitoring of our most precious coastal resources in the tropics. We find that photosynthetic organisms (cyanobacteria, algae) and filter-feeding invertebrates (sponges, ascidians, bivalves, bryozoans) count among the "canaries in the coal mine" as effective indicators of environmental change.

AN - 21195626; 11679440 AB - Quantitative sampling of fiddler crabs was performed in June-July between 1992 and 1994 along transects at three St. Lucie County mosquito impoundments, Florida, running from the Indian River Lagoon (IRL) shore and across the impoundment perimeter dikes, and in one impoundment across the perimeter ditch. A total of 929 specimens representing four species were found: Uca pugilator, Uca rapax, Uca speciosa, and Uca thayeri. The quantitative sampling showed that there was no correlation between the number of Uca burrow openings on the sediment surface and the actual number of crabs in the sediment. Differences were recorded in abundance and distributional patterns between impoundments, but no correlation was recorded between substrate organic content and species distributional patterns. The male/female ratio was close to 1 for all species, except for U. thayeri; the males dominated for this species (ratio, 1.8:1). High water temperatures potentially lethal to fiddler crabs occurred in the impounded marsh in the summer. U. pugilator and U. rapax were unlikely to be impacted by the impoundment flooding as they are highly motile and not very site specific. U. speciosa and U. thayeri were more restricted to the very soft, dark, and wet substrate along perimeter ditch banks and may therefore be impacted during periods of flooding because they are dependent on nonflooded areas for feeding and reproduction.

Collectively, the two datasets represent a unique resource that provides a mechanism to improve our understanding of changing environmental conditions on the Mesoamerican Barrier Reef and, particularly, the conditions governing water quality and movement around Carrie Bow Cay. Especially evident is the broad influence on water quality of seasonal climate patterns as well as short-term events such as cold fronts and major storms. Among several variables examined, wind direction appears to be a good indicator of water quality conditions. From March to June, prevailing northeasterly airflow and limited rainfall result in higher water quality along this portion of the Belize Barrier Reef. Under decreased trade or increasing westerly winds, especially during periods of higher rainfall from October to January, turbid coastal water moves (drifts or is pushed) out onto the reef from the lagoon. The most significant finding, however, has been a dramatic loss of water quality along this portion of the Belize Barrier Reef since monitoring began at Carrie Bow Cay in 1993.

Before the late 1980s, the flanks of the shoals exhibited a distinct biological zonation, with branching Porites spp. dominant in a shallow zone (0-3 m water depth); the stag-horn coral Acropora cervicornis dominant in an intermediate zone (3-15 m depth); and large, plating agariciids and the lettuce coral Agaricia tenuifolia dominant in a deep zone (15-30 m depth). Acropora cervicornis died off catastrophically from white-band disease after 1986 and was replaced by Agaricia tenuifolia in the intermediate zone. Push-cores extracted from intermediate depths in previous studies showed that Acropora cervicornis was the dominant space occupant and primary framework builder for millennia before the phase shift to Agaricia tenuifolia. Cores extracted from the shallow zone showed that Acropora cervicornis dominated until several centuries ago, when the tops of the reefs reached approximately 2 m water depth and branching Porites spp. replaced it. In contrast, three cores extracted from the deep zone in the present study showed that for millennia the subsurface coral assemblage, like the assemblage on the modern deep-reef surface, was dominated by large, plating agariciids and Agaricia tenuifolia. Because white-band disease only affects acroporid corals, the unprecedented phase shift that followed the outbreak was confined to the intermediate zone. High sea temperatures in the summer of 1998 caused coral bleaching and mortality, especially of agariciids in the intermediate and deep zones, but to date this event has not left a geologic signature in the Holocene record.

AN - 21195547; 11679425 AB - The unique, biologically diverse ecosystems of Pelican Cays, Belize, are in serious danger from sediment suffocation related to the recent clear-cutting of mangroves for commercial development in what is currently designated Southwater Cay Marine Reserve. Field observations in the Pelican Cays in March 2007 revealed extensive clear-cutting of mangroves and covering of exposed peat surfaces with sediment dredged from the adjacent seafloor to create false sand cays. On Manatee Cay, introduction of dredge spoils taken from the nearby seabed resulted in fine sediment plumes spilling into the adjacent ponds, smothering the attached benthic communities on mangrove roots and burying Thalassia bottom communities. In addition, comparative studies of microalgal (phytoplankton) assemblages in a Manatee Cay pond before and after mangrove clearing indicate a dramatic loss in this group. This change, related to high turbidity observed in the water column, signals a serious impact to this aquatic ecosystem. In March 2007, clear-cutting, burning, and dredge and fill operations were taking place on Fisherman's Cay, with additional survey lines visible on Fisherman's, Manatee, and Cat Cays. We used a series of aerial photographic surveys from 2003 to 2007 to document the extensive loss of mangroves on both Manatee and Fisherman's Cays. To date, additional clearing of mangroves has occurred on Northeast Cay, Bird Cays, and Ridge Cay, resulting in a total of 15.3 ha or more than 29% of the mangrove community that have been destroyed in the Pelican Cays. Furthermore, several survey lines through still-forested areas on these islands indicated that additional clearing of mangroves was planned. The Pelican Cays ponds contain unique, biologically diverse ecosystems dominated by delicate sessile pho-tosynthetic and filter-feeding populations; these rare communities will be lost as a result of sediment suffocation caused by the clearing and filling of these islands. However, the conversion of mangrove ecosystems for residential, tourism, and commercial uses is both widespread and accelerating in Belize and throughout the global tropics. This pressure is having an adverse effect on the health of coral reefs and the biomass and viability of commercial fisheries, which are essential for both tourism and local livelihoods.

These islands provide critical habitat supporting marine biodiversity and create a self-sustaining system that counterbalances sea-level rise. Undisturbed mangrove islands build vertically through accumulation of organic matter (peat), which forms a strong, erosion-resistant matrix. Clear-cutting and dredging activities for development of tourist resorts, fishing camps, and "improved land" for resale, however, threaten mangrove-dominated islands and adjacent seagrass and coral reef assemblages. Effects of mangrove disturbance were examined on four islands in the designated marine preserves of Twin Cays and the Pelican Cays, Belize. Mangroves were clear cut (1.0-6.2 ha), and marine sediment was dredged from nearby reef flats and seagrass beds to raise land elevations to support beach vegetation and buildings. Removal of mangroves and especially addition of dredged fill significantly altered soil characteristics and decreased shear strength and aggregate stability of soil surfaces. Deep cores collected at both island ranges also revealed underlying deposits of peat (1.5-10.8 m thick), which influence local land subsidence. Although infilling with dredged material temporarily raised elevations, the inexorable subsidence of peat through natural processes of compaction and decomposition and sea-level rise will ultimately submerge such areas. Our findings thus show that soil erosion potential is increased and that long-term stability of islands may be compromised by mangrove clearing and dredging activities. Degradation of key biophysical components and critical habitat will ultimately impact ecotourism activities that depend on a healthy, natural environment.

In the Caribbean, changes in nutrient loading that result from rapid development are thought to have caused increased planktonic productivity, reduced water clarity, and reduced reef and seagrass health. Here we analyze chlorophyll a concentration and water clarity from eight years of environmental monitoring in Bocas del Toro, Panama. Chlorophyll a concentrations did not vary significantly among the six sampled sites and showed no significant temporal changes, despite the recent rapid development in the region, accompanied by scant wastewater treatment. In contrast, water clarity increased significantly during the study period. Because chlorophyll a does not vary closely with water clarity, Secchi depths are likely to reflect changes in suspended particulate matter rather than in phytoplankton biomass. Secchi depths decreased with rainfall and wind speed but increased with solar radiation, supporting the idea that clarity was not tightly linked to phytoplankton biomass. The decrease in annual rainfall, but not wind speed, over the past eight years suggests that the long-term trend in Secchi readings is the result of changes in rainfall patterns.

Results of a monthly survey of the Indian River Area bryozoan fauna carried out in 1974-1975 as part of a postdoctoral fellowship at the Smithsonian Marine Station were published in 1982. The existence of this baseline work made it possible to resurvey some of the same areas during 1998-1999 to determine whether the bryozoan communities at three of the sites in the original study had changed or remained stable. Results showed that most of the species that had been abundant at a site still occurred at that site 24 years later, indicating a high degree of stability. However, there were some important changes. Temperate species such as Hippoporina verrilli, Cryptosula pallasiana, and Bugula stolonifera, which had been abundant in 1974, were rare or absent in 1998. Those species were replaced by Caribbean species, such as Exechonella antillea and Caulibugula armata. Although local seawater temperatures during the time period were not available, the Fort Pierce air temperature records indicated that despite the year-to-year variability in both minimum and maximum temperatures over the seasons, mean winter air temperatures maintained a slow increase from 1974 to 1999.

Funded by a private trust from J. Seward Johnson, Sr., to the Smithsonian, the marine program has supported the research of Smithsonian scientists and their associates, postdoctoral fellows, resident scientists, and the operations of the station, including a small support staff. The station is administered by the National Museum of Natural History as a facility for research dedicated to the marine sciences. The Smithsonian Marine Station at Fort Pierce has developed a strong, broadly based research program focusing on ecology, evolution, systematics, and life histories of marine organisms. Ongoing studies address important issues in biodiversity, including global climate change, invasive species, harmful algal blooms, larval ecology, and evolutionary developmental biology.

One expanding area of research not well emphasized to date is the endocrine effects of Hg. This review summarizes the existing literature on the effects of Hg on the endocrine system and identifies gaps in the knowledge. It focuses on the thyroid, adrenal, and reproductive systems, including the accumulation of Hg in the endocrine system, sex differences that are manifested with Hg exposure, reproductive effects in male and female animals including humans, and Hg effects on the thyroid and adrenal systems. We concluded that there are five main endocrine-related mechanisms of Hg across these systems: (a) accumulation in the endocrine system; (b) specific cytotoxicity in endocrine tissues; (c) changes in hormone concentrations; (d) interactions with sex hormones; and (e) up-regulation or down-regulation of enzymes within the steroidogenesis pathway. Recommendations for key areas of research to better understand how the endocrine effects of Hg affect human and wildlife health were developed, and include increasing the amount of basic biological information available about Hg and wildlife species, exploring the role of Hg in the presence of other stressors and chemicals, understanding sublethal and indirect effects of Hg on adverse outcomes, developing better methods to extrapolate effects across species, and understanding the effects of Hg on multiple organ systems following exposure of an animal. Greater inclusion of endocrine endpoints in epidemiological and field studies on humans and wildlife will also advance the research in this area.

Possible outcomes might include: (1) the extirpation of a species already present in the ecosystem, (2) the exclusion of a new invader, or (3) niche compression, with each species using less of the shared resource. Chthamalus proteus, a barnacle that arrived in the Hawaiian Islands 630 yr ago, is now the most abundant and widespread non-native barnacle in the intertidal zone on the island of Oahu. In a series of field experiments, I demonstrate that the abundance of an earlier invader - the larger, faster growing barnacle Balanus reticulatus - is reduced via substrate pre- emption in the zone of overlap between the 2 barnacle species. A third barnacle, Balanus amphitrite, which invaded Hawaii earlier than the other two, is now virtually absent from locations where it was once abundant and where C. proteus is now the numerical dominant. B. amphitrite did not settle on plates from which C. proteus was removed, suggesting that the presence of C. proteus is not the proximal cause of its decline. B. amphitrite is still present on Oahu, particularly in lower salinity settings. While successively invading barnacles have reportedly replaced each other in other locations around the world, it appears that invasive barnacles on Oahu are undergoing niche compression rather than complete replacement.

We assess the nature of climate-vegetation interaction during two time intervals: middle-late Pennsylvanian transition and Pennsylvanian-Permian transition, each marked by tropical warming and drying. In case study 1, there is a catastrophic intra-biomic reorganization of dominance and diversity in wetland, evergreen vegetation growing under humid climates. This represents a threshold-type change, possibly a regime shift to an alternative stable state. Case study 2 is an inter-biome dominance change in western and central Pangaea from humid wetland and seasonally dry to semi-arid vegetation. Shifts between these vegetation types had been occurring in Euramerican portions of the equatorial region throughout the late middle and late Pennsylvanian, the drier vegetation reaching persistent dominance by Early Permian. The oscillatory transition between humid and seasonally dry vegetation appears to demonstrate a threshold-like behavior but probably not repeated transitions between alternative stable states. Rather, changes in dominance in lowland equatorial regions were driven by long-term, repetitive climatic oscillations, occurring with increasing intensity, within overall shift to seasonal dryness through time. In neither case study are there clear biotic or abiotic warning signs of looming changes in vegetational composition or geographic distribution, nor is it clear that there are specific, absolute values or rates of environmental change in temperature, rainfall distribution and amount, or atmospheric composition, approach to which might indicate proximity to a terrestrial biotic-change threshold.

All previous studies of endophyte-herbivore interactions have occurred in temperate areas, and many use correlations rather than experiments. In Panama, Glomerella cingulata is a common endophyte species found in healthy leaves, and Chelymorpha alternans is a common herbivore on Merremia umbellata, a tropical vine. We manipulated the abundance of G. cingulata in the leaves of M. umbellata. We then assessed the effects of high and low endophyte densities on the food choice, development, and reproductive success of the leaf beetle, C. alternans. In 'choice' experiments, adult females with a history of feeding on wild plants showed no preference when offered food plants with high and low endophyte densities. Further, in 'no-choice' experiments, C. alternans larvae that were fed high- or low-density endophyte leaves did not differ in development or survivorship. However, when larvae fed on leaves with low endophyte densities became adults, they produced 80 percent more offspring. This suggests high endophyte levels in hosts can have a negative effect on herbivore fecundity. Further experiments are necessary to understand whether the reproductive effects are due to feeding on low-density endophytes in the larval or adult stages, and whether changes in reproductive success are motivated by the adult's perception of food quality or by physiological constraint due to food quality. RESUMENLos hongos endofitos foliares viven dentro de tejido sano de las hojas y en algunos casos le confieren resistencia contra herbivoria al hospedero. Todos los estudios previos sobre interacciones endofitos-herbivoros han ocurrido en zonas templadas y muchos utilizan correlaciones en lugar de experimentos. En Panama Glomerella cingulata es una especie de endofito comun que se encuentra dentro de tejido sano de las hojas y Chelymorpha alternans es un herbivoro comun de la liana tropical Merremia umbellata. Manipulamos la abundancia de G. cingulata dentro de las hojas de M. umbellata. Luego determinamos los efectos de alta y baja densidad de endofitos sobre la escogencia de comida, desarrollo y exito reproductivo del escarabajo de hoja C. alternans. En los experimentos de 'escogencia', hembras adultas que previamente se alimentaron con hojas silvestres, no mostraron preferencia cuando se les ofrecieron hojas con alta y baja densidad de endofitos. Sin embargo, larvas que se alimentaron con hojas de baja densidad produjeron 80% mas descendientes una vez alcanzado su estado adulto. Esto sugiere que altos niveles de hongos endofitos en el hospedero puede tener un efecto negativo en la fecundidad de los herbivoros. Experimentos en el futuro son necesarios para entender si los efectos reproductivos se deben a la alimentacion con baja densidad de endofitos en el estado larval o adulto, y si cambios en el exito reproductivo son motivados por la percepcion del adulto sobre la calidad de la comida o por limitaciones fisiologicas causadas por la calidad de la comida.

This paper summarizes past and present research and strategies for the prevention and control of K. brevis blooms. Prevention presumes a certain level of understanding about the cause or causes of these blooms. This may not yet be available, however, for K. brevis in the Gulf of Mexico. Some efforts to synthesize the current understanding of bloom dynamics for the region were recommended. The earliest attempts to control K. brevis blooms in the field used copper sulfate minerals seeded from ships and crop-dusting planes. Although effective for short term applications, the method was abandoned as it provided only temporary relief at a high cost with unknown collateral damage to the ecosystem. Results from chemical screenings and ozone treatments were also presented. Algicidal bacteria have shown some promise in controlling K. brevis in laboratory experiments, either through direct contact or release of algicidal compounds. Finally, the state of the research into the use of natural clays was presented, beginning with laboratory and mesocosm tests, to larger-scale experiments and flume studies. Several impacts studies were reviewed. While much progress has been made in examining control methods in recent years, more research in the field is needed to fully evaluate the efficacy and impacts of these strategies. Furthermore, the social and human dimensions of this potentially controversial area of research may have to be explored more fully to gauge the receptiveness of the public to these management approaches.

Questions remain about how and when foxes first colonized the islands, with researchers speculating on a natural, human-assisted, or combined dispersal during the late Pleistocene and/or Holocene. A natural dispersal of foxes to the northern Channel Islands has been supported by reports of a few fox bones from late Pleistocene paleontological localities. Direct AMS super(1) super(4)C dating of these ''fossil'' fox bones produced dates ranging from ~6400 to 200 cal yr BP, however, postdating human colonization of the islands by several millennia. Although one of these specimens is the earliest securely dated fox from the islands, these new data support the hypothesis that Native Americans introduced foxes to all the Channel Islands in the early to middle Holocene. However, a natural dispersal for the original island colonization cannot be ruled out until further paleontological, archaeological, and genetic studies (especially aDNA [ancient DNA]) are conducted.

Published research indicates that within and near oxygen-depleted waters, finfish and mobile crustaceans experience negative effects that range from mortality to altered trophic interactions. Chronic exposure to hypoxia and fluctuating oxygen concentrations impair reproduction, immune responses, and growth.We present an analysis of hypoxia, nitrogen loadings, and fisheries landings in 30 estuaries and semienclosed seas worldwide. Our results suggest that hypoxia does not typically reduce systemwide fisheries landings below what would be predicted from nitrogen loadings, except where raw sewage is released or particularly sensitive species lose critical habitat. A number of compensatory mechanisms limit the translation of local-scale effects of hypoxia to the scale of the whole system. Hypoxia is, however, a serious environmental challenge that should be considered in fisheries management strategies and be the direct target of environmental restoration.

Two new reference materials were prepared at the Smithsonian Institution, to provide an avenue to pursue the geochemical analysis of micas and feldspars in granitic pegmatites: STL-1, the Stewart lepidolite (NMNH 174041) and ZA-1, the Zapot amazonite (NMNH 174042). STL-1 was prepared from lepidolite collected from the lithium-rich Stewart pegmatite, San Diego County, California (33 degrees 22'52"N, 117 degrees 03'41"W). ZA-1 was prepared from an amazonite from the topaz-bearing Zapot pegmatite, Mineral County, Nevada, (38 degrees 41'N, 118 degrees 33'W). The results of this study indicated that STL-1 and ZA-1 are homogeneous and could be used as reference materials that would allow the expansion of calibration curves in XRF analysis up to 16000 mu g g (super -1) for Rb, 2000 mu g g (super -1) for Cs and 100 mu g g (super -1) for Tl. STL-1 and ZA-1 also contain unusually high concentrations of Ga and Tl, and STL-1 of Nb. Abstract Copyright (2009), International Association of Geoanalysts.

Cobbles and marine sediments deposited during the high-energy transgressive phase exhibit rim cements indicating a subsequent phreatic environment. This was succeeded stratigraphically by a still-stand deposition of fine calcareous lagoonal sediments containing bioclasts of red algae and benthic and planktonic foraminifera that was intensely burrowed by marine invertebrates, probably upogebiid shrimp, that could not be produced under any condition other than sustained marine submergence. Overlying this were pure carbonate beach sands of a low-energy regressive phase containing abundant remains of terrestrial and marine vertebrates and invertebrates. The considerable diversity of this fauna along with taphonomic evidence from seabird remains indicates deposition by high run-up waves over a minimum duration of months, if not years. The maximum duration has yet to be determined but probably did not exceed one or two thousand years. The most abundant snails in this fauna are two species indicative of brackish water and high-tide line showing that a Ghyben-Herzberg lens must have existed at >+20 m. The nature of these sediments and fossil accumulation is incompatible with tsunami deposition and, given the absence of evidence for tectonic uplift of the Bermuda pedestal or platform, provide proof that sea-level during MIS 11 exceeded +20 m, a fact that has widespread ramifications for geologists, biogeographers, and human demographics along the world's coastlines.

South of 4 degrees 30'N lat, early syn-rift alluvial sequences in former extensional footwall areas were contemporaneous with fan-delta deposits in shallow marine environments in adjacent hanging-wall areas. In general, footwall erosion was more pronounced in the southern part of the paleorift. In contrast, early syn-rift sequences in former footwall areas in the northern rift sectors mainly comprise shallow marine supratidal sabkha to intertidal strata, whereas hanging-wall units display rapid transitions to open-sea shales. In comparison with the southern paleo-rift sector, fan-delta deposits in the north are scarce, and provenance suggests negligible footwall erosion. The southern graben segment had longer, and less numerous normal faults, whereas the northern graben segment was characterized by shorter, rectilinear faults. To the east, the graben system was bounded by major basin-margin faults with protracted activity and greater throw as compared with intrabasinal faults to the west. Intrabasinal structures grew through segment linkage and probably interacted kinematically with basin-margin faults. Basin-margin faults constitute a coherent fault system that was conditioned by pre-existing basement fabrics. Structural mapping, analysis of present-day topography, and balanced cross sections indicate that positive inversion of extensional structures was focused along basin-bounding faults, whereas intrabasinal faults remained unaffected and were passively transported by motion along the basin-bounding faults. Thus, zones of maximum subsidence in extension accommodated maximum elevation in contraction, and former topographic highs remained as elevated areas. This documents the role of basin-bounding faults as multiphased, long-lived features conditioned by basement discontinuities. Inversion of basin-bounding faults was more efficient in the southern than in the northern graben segment, possibly documenting the inheritance and pivotal role of fault-displacement gradients. Our observations highlight similarities between inversion features in orogenic belts and intra-plate basins, emphasizing the importance of the observed phenomena as predictive tools in the spatiotemporal analysis of inversion histories in orogens, as well as in hydrocarbon and mineral deposits exploration.

Two contemporaneous river systems deposited the sediments of this interval, with a mountain-sourced system (herein, Blue-gray) to the southwest interfingering with a foothill-sourced system (Buff) to the northeast. Fossil mammal teeth collected from a 32 km transect across this fluvial gradient are significantly more depleted in (super 13) C from northeastern localities than from southwestern localities. This trend occurs in equids, giraffids, suids, sivapithecine hominoids, and anthracotheres. We propose that the Buff fluvial system provided more equably moist substrate conditions and supported more closed-canopy vegetation than the Blue-gray fluvial system. Herbivores living along the paleovegetation gradient thus acquired different carbon isotopic signatures during the period of tooth enamel formation, resulting from higher delta (super 13) C values in the forage supported by the Blue-gray fluvial system compared with forage associated with the Buff system. The data also imply that many Siwalik mammalian herbivores displayed marked fidelity in juvenile home ranges and habitats.

Here, we report hominin footprints in two sedimentary layers dated at 1.51 to 1.53 million years ago (Ma) at Ileret, Kenya, providing the oldest evidence of an essentially modern human-like foot anatomy, with a relatively adducted hallux, medial longitudinal arch, and medial weight transfer before push-off. The size of the Ileret footprints is consistent with stature and body mass estimates for Homo ergaster/erectus, and these prints are also morphologically distinct from the 3.75-million-year-old footprints at Laetoli, Tanzania. The Ileret prints show that by 1.5 Ma, hominins had evolved an essentially modern human foot function and style of bipedal locomotion.

Recently developed methodologies in the archaeological and biological sciences are providing increasing amounts of data regarding the timing and nature of these dispersals and the associated transition to food production in various regions. One of these methodologies, starch grain analysis, recovers identifiable microfossils of economic plants directly off the stone tools used to process them. We report on new starch grain evidence from Panama demonstrating the early spread of three important New World cultigens: maize (Zea mays), manioc (Manihot esculenta), and arrowroot (Maranta arundinacea). Maize starch recovered from stone tools at a site located in the Pacific lowlands of central Panama confirms previous archaeobotanical evidence for the use of maize there by 7800-7000 cal BP. Starch evidence from preceramic sites in the less seasonal, humid premontane forests of Chirique province, western Panama, shows that maize and root crops were present by 7400-5600 cal BP, several millennia earlier than previously documented. Several local starchy resources, including Zamia and Dioscorea spp., were also used. The data from both regions suggest that crop dispersals took place via diffusion or exchange of plant germplasm rather than movement of human populations practicing agriculture.

Mothers in good condition may produce infants who weigh more, grow faster, and are more likely to survive than the infants of mothers in poor condition. These effects may be partially mediated through the quantity and quality of milk that mothers produce during lactation. However, we know relatively little about the relationships between maternal condition, milk composition, milk yield, and infant outcomes. Here, we present the first systematic investigation of the magnitude, sources, and consequences of individual variation in milk for an Old World monkey. Rhesus macaques produce dilute milk typical of the primate order, but there was substantial variation among mothers in the composition and amount of milk they produced and thus in the milk energy available to infants. Relative milk yield value (MYV), the grams of milk obtained by mammary evacuation after 3.5-4 h of maternal-infant separation, increased with maternal parity and was positively associated with infant weight. Both milk gross energy (GE) and MYV increased during lactation as infants aged. There was, however, a trade-off; those mothers with greater increases in GE had smaller increases in MYV, and their infants grew more slowly. These results from a well-fed captive population demonstrate that differences between mothers can have important implications for milk synthesis and infant outcome. Copyright John Wiley & Sons.

To understand how diet and ecology affect the social behavior of ring-tailed coatis (Nasua nasua), detailed measures of feeding behavior were recorded from 2 well-studied groups over a 2-year period. The proportion of fruit and invertebrates in the diet of ring-tailed coatis in Iguazu, Argentina, was very similar to that in diets of white-nosed coatis (N. narica) and ring-tailed coatis studied at field sites in Brazil. Consumption of vertebrates in Iguazu was exceptionally rare. The proportion of time spent foraging for invertebrates and fruit generally matched seasonal changes in the abundance these foods in the environment. During the winter, when invertebrate and fruit availability was low, coatis spent a large amount of time feeding on 2 exotic fruit species. The presence of exotic fruits provided coatis with food during the lean winter season and may have influenced the high reproduction and survivorship found in this population. Coatis spent about 44% of their fruit-foraging time exploiting pindo palm (Syagrus romanzoffianum) fruits and it appeared that this fruit species played a major role in shaping the ranging and feeding behavior of coati groups. The time spent foraging at fruit trees and the total number of fruits eaten varied depending on the species of tree. Coati groups spent an average of 2.5-12.5 min feeding on different species of fruit trees, and coati groups ate an average of 2.6-269.8 fruits per tree species. The quick depletion of fruit trees and high density of foraging individuals, especially when feeding on pindo, plays an important role in shaping the social system of coatis.

Facultative dim-light foraging behaviour is known in five of nine families of bees, while obligate behaviour is known in four families and evolved independently at least 19 times. The light intensity under which bees forage varies by a factor of 108, and therefore the evolution of dim-light foraging represents the invasion of a new, extreme niche. The repeated evolution of dim-light foraging behaviour in bees allows tests of the hypothesis that behaviour acts as an evolutionary pacemaker. With the exception of one species of Apis, facultative dim-light foragers show no external structural traits that are thought to enable visually mediated flight behaviour in low-light environments. By contrast, most obligate dim-light foragers show a suite of convergent optical traits such as enlarged ocelli and compound eyes. In one intensively studied species (Megalopta genalis) these optical changes are associated with neurobiological changes to enhance photon capture. The available ecological evidence suggests that an escape from competition for pollen and nectar resources and avoidance of natural enemies are driving factors in the evolution of obligate dim-light foraging.

The thylacine's phylogenetic position within australidelphian marsupials has long been debated, and here we provide strong support for the thylacine's basal position in Dasyuromorphia, aided by mitochondrial genome sequence that we generated from the extant numbat (Myrmecobius fasciatus). Surprisingly, both of our thylacine sequences differ by 11%-15% from putative thylacine mitochondrial genes in GenBank, with one of our samples originating from a direct offspring of the previously sequenced individual. Our data sample each mitochondrial nucleotide an average of 50 times, thereby providing the first high-fidelity reference sequence for thylacine population genetics. Our two sequences differ in only five nucleotides out of 15,452, hinting at a very low genetic diversity shortly before extinction. Despite the samples' heavy contamination with bacterial and human DNA and their temperate storage history, we estimate that as much as one-third of the total DNA in each sample is from the thylacine. The microbial content of the two thylacine samples was subjected to metagenomic analysis, and showed striking differences between a wild-captured individual and a born-in-captivity one. This study therefore adds to the growing evidence that extensive sequencing of museum collections is both feasible and desirable, and can yield complete genomes.

Forst. & G. Forst. (Rutaceae) were examined by generating phylogenetic hypotheses based on chloroplast and nuclear ribosomal sequence data. The aims of the study were to identify the number of colonization events of Melicope to the Hawaiian Islands and to reveal the relationship of Hawaiian Melicope to the Hawaiian endemic genus Platydesma H. Mann. The ultimate goal was to determine if the Hawaiian Islands served as a source area for the colonization of Polynesia.LocationNineteen accessions were sampled in this study, namely eight Melicope species from the Hawaiian Islands, four from the Marquesas Islands, one species each from Tahiti, Australia and Lord Howe Island, two Australian outgroups and two species of the Hawaiian endemic genus Platydesma. To place our results in a broader context, 19 sequences obtained from GenBank were included in an additional analysis, including samples from Australia, Papua New Guinea, New Zealand, Southeast Polynesia and Asia.MethodsDNA sequences were generated across 19 accessions for one nuclear ribosomal and three chloroplast gene regions. Maximum parsimony analyses were conducted on separate and combined data sets, and a maximum likelihood analysis was conducted on the combined nuclear ribosomal and chloroplast data set. A broader nuclear ribosomal maximum parsimony analysis using sequences obtained from GenBank was also performed. Geographic areas were mapped onto the combined chloroplast and nuclear ribosomal tree, as well as onto the broader tree, using the parsimony criterion to determine the dispersal patterns.ResultsPhylogenetic analyses revealed that Platydesma is nested within Melicope and is sister to the Hawaiian members of Melicope. The Hawaiian Melicope+Platydesma lineage was a result of a single colonization event, probably from the Austral region. Finally, Marquesan Melicope descended from at least one, and possibly two, colonization events from the Hawaiian Islands.Main conclusionsThese data demonstrate a shifting paradigm of Pacific oceanic island biogeography, in which the patterns of long-distance dispersal and colonization in the Pacific are more dynamic than previously thought, and suggest that the Hawaiian Islands may act as a stepping stone for dispersal throughout the Pacific.

Eleven years exposure to elevated CO2 caused a 67% increase in aboveground shoot biomass. Growth stimulation was sustained throughout the experiment; although there was significant variability between years. The absolute stimulation of aboveground biomass generally declined over time, reflecting increasing environmental limitations to long-term growth response. Extensive defoliation caused by hurricanes in September 2004 was followed by a strong increase in shoot density in 2005 that may have resulted from reopening the canopy and relocating nitrogen from leaves to the nutrient-poor soil. Biomass response to elevated CO2 was driven primarily by stimulation of growth of the dominant species, Quercus myrtifolia, while Quercus geminata, the other co-dominant oak, displayed no significant CO2 response. Aboveground growth also displayed interannual variation, which was correlated with total annual rainfall. The rainfall CO2 interaction was partially masked at the community level by species-specific responses: elevated CO2 had an ameliorating effect on Q. myrtifolia growth under water stress. The results of this long-term study not only show that atmospheric CO2 concentration had a consistent stimulating effect on aboveground biomass production, but also showed that available water is the primary driver of interannual variation in shoot growth and that the long-term response to elevated CO2 may have been caused by other factors such as nutrient limitation and disturbance.

Although slow-freezing cryopreservation of zebrafish sperm has been available for 30 years, current protocols lack standardization and yield inconsistent post-thaw fertilization rates. Cell cryopreservation cannot be improved without basic physiological knowledge, which was lacking for zebrafish sperm. The first goal was to define basic cryobiological values for wild-type zebrafish sperm and to evaluate how modern physiological methods could aid in developing improved cryopreservation protocols. Coulter counting methods measured an osmotically inactive water fraction (Vb) of 0.37+/-0.02 (SEM), an isosmotic cell volume (V sub(o)) of 12.1+/-0.2 mu m super(3) (SEM), a water permeability (L sub(p)) in 10% dimethyl sulfoxide of 0.021+/-0.001(SEM) mu m/min/atm, and a cryoprotectant permeability (P sub(s)) of 0.10+/-0.01 (SEM)x10 super(-) super(3)cm /min. Fourier transform infrared spectroscopy indicated that sperm membranes frozen without cryoprotectant showed damage and lipid reorganization, while those exposed to 10% glycerol demonstrated decreased lipid phase transition temperatures, which would stabilize the cells during cooling. The second goal was to determine the practicality and viability of shipping cooled zebrafish sperm overnight through the mail. Flow cytometry demonstrated that chilled fresh sperm can be maintained at 92% viability for 24h at 0 super(o)C, suggesting that it can be shipped and exchanged between laboratories. Additional methods will be necessary to analyze and improve cryopreservation techniques and post-thaw fertility of zebrafish sperm. The present study is a first step to explore such techniques.

Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae--popularly called jellyfish--and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand's fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum-freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae.

Snails, limpets, sea slugs, terrestrial slugs, clams, mussels, oysters, and squids are all molluscs. They are economically and culturally important. Scientifically, they are considered one of the better-known invertebrate phyla, yet the species-level taxonomy of many groups is poorly understood and we know virtually nothing about the life-history characters of most living species. The phylum name (from Latin molluscus, soft) reflects the soft body of molluscs, protected by shell in a majority of species.

N1 - Last updated - 2012-06-07 ER - TY - JOUR T1 - STATIC ALLOMETRY AND ANIMAL GENITALIA AN - 907152401; 14135446 AB - A survey of 117 species of arthropods and 17 species of vertebrates showed a strong trend for male genitalia to have relatively low static allometric values. This trend contrasts with the allometry of other structures under sexual selection, which usually show steep allometric slopes. The trend to low allometric genital values is less consistent in mammals than in arthropods. Data not in accord with the previous the "one-size-fits-all" explanation for low allometric slopes in genitalia, which was based on sexual selection by female choice, suggest a more general version that includes both natural selection and sexual selection, and involves both mechanical fit and stimulation. Less-complete data on the female genitalia of arthropods suggest a trend to similar low allometric slopes, and may also be explained by mechanical fit and stimulatory one-size-fits-all arguments.

But self-gravity's role at earlier times (and on larger length scales, such as similar to 1parsec) is unclear; some molecular cloud simulations that do not include self-gravity suggest that 'turbulent fragmentation' alone is sufficient to create a mass distribution of dense cores that resembles, and sets, the stellar initial mass function. Here we report a 'dendrogram' (hierarchical tree-diagram) analysis that reveals that self-gravity plays a significant role over the full range of possible scales traced by super(13)CO observations in the L1448 molecular cloud, but not everywhere in the observed region. In particular, more than 90 per cent of the compact 'pre-stellar cores' traced by peaks of dust emission are projected on the sky within one of the dendrogram's self-gravitating 'leaves'. As these peaks mark the locations of already-forming stars, or of those probably about to form, a self-gravitating cocoon seems a critical condition for their existence. Turbulent fragmentation simulations without self-gravity-even of unmagnetized isothermal material-can yield mass and velocity power spectra very similar to what is observed in clouds like L1448. But a dendrogram of such a simulation shows that nearly all the gas in it (much more than in the observations) appears to be self-gravitating. A potentially significant role for gravity in 'non-self-gravitating' simulations suggests inconsistency in simulation assumptions and output, and that it is necessary to include self-gravity in any realistic simulation of the star-formation process on subparsec scales.

Consequently, controls underlying the size spectrum of the global biota have been difficult to evaluate. Our period-level compilation of the largest known fossil organisms demonstrates that maximum size increased by 16 orders of magnitude since life first appeared in the fossil record. The great majority of the increase is accounted for by 2 discrete steps of approximately equal magnitude: the first in the middle of the Paleoproterozoic Era ( nearly equal 1.9 Gya) and the second during the late Neoproterozoic and early Paleozoic eras (0.6-0.45 Gya). Each size step required a major innovation in organismal complexity-first the eukaryotic cell and later eukaryotic multicellularity. These size steps coincide with, or slightly postdate, increases in the concentration of atmospheric oxygen, suggesting latent evolutionary potential was realized soon after environmental limitations were removed.

Several modes of origin have been proposed for the Argyre ridges. Imagery from the High Resolution Imaging Science Experiment (HiRISE) and Context Camera (CTX) aboard Mars Reconnaissance Orbiter (MRO) and Mars Orbiter Laser Altimeter (MOLA) topographic data sets from Mars Global Surveyor (MGS) are used to constrain processes involved in formation of the Argyre ridges. We find the characteristics of the ridges and associated layered deposits consistent with glaciofluvial-lacustrine processes and conclude that the ridges are most likely eskers. In particular, variations in ridge height appear to be related to the surrounding surface slope; ridge height increases with descending slopes and decreases with ascending slopes. This characteristic is observed in terrestrial eskers and is related to subice flow processes. The nature of some eroding beds in the ridges suggests induration. If the Argyre ridges are indeed eskers, the southern Argyre basin was once covered by the margin of a large, thick, stagnating or retreating ice deposit that extended for hundreds of kilometers or more. During ridge formation, water flowed on top, within, or beneath the ice deposit; the continuity and preservation of the ridges suggests that flow was primarily at the base of the ice. The dimensions (up to hundreds of meters tall and several kilometers wide), aspect ratio, and extent (hundreds of kilometers) of the ridges, as well as preliminary calculations of discharge, suggest that a significant amount of water was available.

In a tropical montane rainforest ecosystem in southern Ecuador, plot-scale investigations revealed that man-made disturbances were accompanied by a decrease in mean saturated hydraulic conductivity (Ks), whereas mean Ks of two different aged landslides was undistinguishable from the reference forest. Ks spatial structure weakened after disturbances in the topsoil. We used this spatial-temporal information combined with local rain intensities to assess the probability of impermeable soil layers under undisturbed, disturbed, and regenerating land-cover types. We furthermore compared the Ecuadorian man-made disturbance cycle with a similar land-use sequence in a tropical lowland rainforest region in Brazil. The studied montane rainforest is characterized by prevailing vertical flowpaths in the topsoil, whereas larger rainstorms in the study area potentially result in impermeable layers below 20 cm depth. In spite of the low frequency of such higher-intensity events, they transport a high portion of the annual runoff and may therefore significant for the regional water cycle. Hydrological flowpaths under two studied landslides are similar to the natural forest except for a somewhat higher probability of impermeable layer formation in the topsoil of the 2-year-old landslide. In contrast, human disturbances likely affect near-surface hydrology. Under a pasture and a young fallow, impermeable layers potentially develop already in the topsoil for larger rain events. A 10-year-old fallow indicates regeneration towards the original vertical flowpaths, though the land-use signal was still detectable. The consequences of land-cover change on near-surface hydrological behaviour are of similar magnitude in the tropical montane and the lowland rainforest region. This similarity can be explained by a more pronounced drop of soil permeability after pasture establishment in the montane rainforest region in spite of the prevailing much lower rain intensities.

Morphologists have considered these groups phylogenetically distinct from each other, but the three lineages appear to be related as a monophyletic Family Spalacidae, sister taxon to all other living muroids, based on both nuclear and mitochondrial genes. Although living genera are fully subterranean, the fossil record shows that the three groups evolved burrowing characteristics independently. Bamboo rats (Rhizomyinae) have the longest fossil record, extending into the Late Oligocene, but do not show fossorial traits until the Late Miocene. Blind mole rats (Spalacinae) have a fossil record nearly that long, and its early members also lack burrowing traits. Zokors (Myospalacinae) show characteristics considered derived relative to other groups, and have a shorter fossil record. The fossil record of the Tribe Rhizomyini, living Asian bamboo rats, extends to about 10 million years ago, with early species distinct at the generic level from living Rhizomys. The oldest wellknown species assignable to an extant genus is Rhizomys (Brachyrhizomys) shansius from the early Pliocene of Yushe Basin, China, north of the geographic range of modern Rhizomys. A hypothesis of close relationship of bamboo rats, blind mole rats, and zokors leads to a reevaluation of affinities of certain Asian fossil taxa and reevaluation of polarity of some features, but molecular data are not yet robust enough to clarify interrelationships of the groups. Morphological and fossil data suggest that myospalacines are more closely related to rhizomyines than to spalacines, and that known Early Miocene rhizomyines are close to the stem zokor morphotype.

The interfaces occur in two locations; a northern flow that originates south of Alba Patera, and a southern flow that originates at the rift zone between Ascraeus and Pavonis Montes. The northern flow has permittivity values, estimated from the time delay of echoes from the basal interface, between 6.2 and 17.3, with an average of 12.2. The southern flow has permittivity values of 7.0 to 14.0, with an average of 9.8. The average permittivity values for the northern and southern flows imply densities of 3.7 and 3.4 g cm (super -3) , respectively. Loss tangent values for both flows range from 0.01 to 0.03. The measured bulk permittivity and loss tangent values are consistent with those of terrestrial and lunar basalts, and represent the first measurement of these properties for dense rock on Mars.

New 70-cm wavelength radar observations that probe several meters beneath the lunar surface reveal differences in mare backscatter properties not explained by age or compositional variations. We interpret areas of high backscatter and high circular polarization ratio in Maria Serenitatis, Imbrium, and Crisium as having an enhanced abundance of decimeter-scale subsurface rocks relative to typical mare-forming flows. The 3.5 b.y survival of these differences implies an initial platy, blocky, or ridged lava flow surface layer with thickness of at least 3-5 m. Such rugged morphology might arise from episodic changes in magma effusion rate, as observed for disrupted flood basalt surfaces on the Earth and Mars, very high flow velocities, or increased viscosity due to a number of factors. Significant information on lunar mare eruption conditions may thus be obtained from long-wavelength radar probing of the shallow subsurface.

And yet, the geographical bias of pertinent previous studies and their methodologies and approaches to data analysis cast a doubt on the general validity of claims regarding spatial and temporal patterns of throughfall. We employed 220 collectors in a 1-ha plot of semideciduous tropical rain forest in Panama and sampled throughfall during a period of 14 months. Our analysis of spatial patterns is based on 60 data sets, whereas the temporal analysis comprises 91 events. Both data sets show skewed frequency distributions. When skewness arises from large outliers, the classical, nonrobust variogram estimator overestimates the sill variance and, in some cases, even induces spurious autocorrelation structures. In these situations, robust variogram estimation techniques offer a solution. Throughfall in our plot typically displayed no or only weak spatial autocorrelations. In contrast, temporal correlations were strong, that is, wet and dry locations persisted over consecutive wet seasons. Interestingly, seasonality and hence deciduousness had no influence on spatial and temporal patterns. We argue that if throughfall patterns are to have any explanatory power with respect to patterns of near-surface processes, data analytical artifacts must be ruled out lest spurious correlation be confounded with causality; furthermore, temporal stability over the domain of interest is essential.

The regional population of Common Bush- Tanager (Chlorospingus ophthalmicus) showed a pattern of spatial separation of 1st-year individuals vs. adults, a pattern not shown so far for any bird species. During the early post-breeding season, I captured similar numbers of adult individuals in both natural and young secondary forest (38 vs. 43), while 1st-year individuals were captured mainly in young secondary vegetation (3 vs. 40). The findings indicate that inexperienced, young or less competitive individuals may use other habitats than adults, at least temporarily.

The results demonstrate unexpected instability and high amplitude fluctuations of species diversity in the tropical deep ocean that are correlated with orbital-scale oscillations in global climate: Species diversity is low during glacial and high during interglacial periods. This implies that climate severely influences deep-sea diversity, even at tropical latitudes, and that deep-sea LSDGs, while generally present for the last 36 million years, were weakened or absent during glacial periods. Temporally dynamic LSDGs and unstable tropical diversity require reconsideration of current ecological hypotheses about the generation and maintenance of biodiversity as they apply to the deep sea, and underscore the potential vulnerability and conservation importance of tropical deep-sea ecosystems.

Radar images were obtained for Mare Vaporum and the southern half of Mare Serenitatis; the imaged areas contain the large Rima Bode, Mare Vaporum, Sulpicius Gallus, and Taurus-Littrow pyroclastic deposits. Potential pyroclastic deposits at Rima Hyginus crater, the Tacquet Formation, and a dome in Mare Vaporum are also included. Data were acquired at S band (12.6 cm wavelength) using Arecibo Observatory and the Green Bank Telescope in a bistatic configuration. The S band images have resolutions between 20 and 100 m/pixel. The pyroclastic deposits appear dark to the radar and have low circular polarization ratios at S band wavelengths because they are smooth, easily penetrable by radar waves, and generally contain few embedded blocks. Changes in circular polarization ratio (CPR) across some of the pyroclastic deposits show areas with increased rock abundance as well as deposits that are shallower. Radar backscatter and CPR maps are used to identify fine-grained mantling deposits in cases where optical and near-infrared data are ambiguous about the presence of pyroclastics. The Tacquet Formation in southern Serenitatis, areas near Hyginus crater, and a dome in Mare Vaporum have lower-backscatter cross sections than would be expected for mare basalts of similar estimated titanium content. Combined with very low CPR values, this is strong evidence that these areas are covered in fine-grained pyroclastic mantling material.

The thermal conductivities of the cemented sample were approximately 3X higher, over the range of atmospheric pressures tested, than the thermal conductivities of the same sample after the cement bonds were broken. A thermal conductivity-derived particle size was determined for each sample by comparing these thermal conductivity measurements to previous data that demonstrated the dependence of thermal conductivity on particle size. Actual particle-size distributions were determined via physical separation through brass sieves. When uncemented, 87% of the particles were less than 125 mu m in diameter, with 60% of the sample being less than 63 mu m in diameter. As much as 35% of the cemented sample was composed of conglomerate particles with diameters greater than 500 mu m. The thermal conductivities of the cemented sample were most similar to those of 500-mu m glass beads, whereas the thermal conductivities of the uncemented sample were most similar to those of 75-mu m glass beads. This study demonstrates that even a small amount of salt cement can significantly increase the thermal conductivity of particulate materials, as predicted by thermal modeling estimates by previous investigators.

The network has baseline lengths of approximately 10, 100, and 1000 m. Baseline time series have root mean square (RMS) residuals, about a model for the seasonal cycle, of 0.05-0.24 mm for the horizontal components and 0.20-0.72 mm for the radial. Seasonal cycles occur, with amplitudes of 0.04-0.60 mm, even for the horizontal components and even for the shortest baselines. For many time series these lag seasonal cycles in local temperature measurements by 23-43 days. This could suggest that they are related to bedrock thermal expansion. Both shorter-period signals and seasonal cycles for shorter baselines to REP2, the one short-braced monument in our network, are correlated with temperature, with no lag time. Differences between REP2 and the other stations, which are deep-braced, should reflect processes occurring in the upper few meters of the ground. These correlations may be related to thermal expansion of these upper ground layers, and/or thermal expansion of the monuments themselves. Even over these short distances we see a systematic increase in RMS values with increasing baseline length. This, and the low RMS levels, suggests that site-specific effects are unlikely to be the limiting factor in the use of similar GPS sites for geophysical investigations.

AN - 742914125; 2010-054884 AB - In quantitative phytolith analysis, chance error associated with insufficient counts can affect the robustness of the interpretation, whether it is vegetation reconstruction or taxonomic differentiation. It is therefore vital to choose a count size that will ensure statistically reliable results, while minimizing the time expended. Numerical statistical methods (bootstrapping) that have become available over the past few decades have made it possible to model even complex phytolith assemblages with relative ease. This study used bootstrapping as well as analytic statistical formulas to evaluate the influence of count size on vegetation reconstruction by means of two commonly used indices, D/P (tree cover index) and I (sub ph) (aridity index). The analysis indicates that the count size needed to ensure statistical precision depends on the question as well as the observed assemblage composition. Importantly, it is the count of specimens relevant to a specific ratio or other index ("index-specific" count) that matters, whereas the total count is less important. Based on these results, some general guidelines for choice of count size and for the use of statistics in phytolith analysis are suggested.
