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.

We used rover-inspired methods of remote hand lens-scale data acquisition to conduct reconnaissance of a well-characterized Martian analog field site. The objective was to determine if the current methodologies associated with the use of remote hand lens-scale imagers maximizes science return. Field geologists provided with hand lens-scale images of targets in geologic context could correctly identify many important characteristics of those targets. However, they could not fully confirm or rule out any formation hypothesis using the data provided solely through rover-driven observational strategies. This was due to (1) a lack of "intermediate-scale", or millimeter- to centimeter-scale images providing important contextual information for the targets studied and (2) the limited number of hand lens-scale images that were taken using rover-driven methodology. We conclude that the benefits of the hand lens as an effective triage tool and discriminator of microtexture are limited using current rover-driven methodology because the hand lens-type imager is not deployed frequently, and resulting data cannot be used to fully support geochemical observations. We recommend pursuing ways to increase the number of images that can reasonably be acquired at the hand lens scale. In order for hand lens-scale imaging to be fully effective, textural characteristics diagnostic of the nature of a geologic site need to be identifiable at a number of different resolutions; rover microscale observational strategies must include more contextual imaging.

Levee formation can be attributed to two end-member processes during emplacement: construction during passage of the flow front and growth along the entire length of the flow while it is active. It is shown here that the amount of lava that can be deposited by the flow front alone is limited. Estimates of the levee volume for many Mars plains flows exceed this limit and must have formed by processes that continued after the passage of the front. Experimental studies of analogous laboratory flows also indicate a combination of both modes of emplacement. A model that combines both modes of levee formation is presented, including a method for estimating volumetric flow rate, eruption duration, and viscosity. Six lava flows on the plains of the Tharsis volcanic province are used as illustrative examples. Crustal thicknesses for the six flows examined range from 9 to 23 m. Estimated emplacement times required to cool crusts of these thicknesses range from 1 year to 10 years. Corresponding viscosities are on the order of 10 (super 5) -10 (super 6) Pa s. Effusion rates range from 25 to 840 m (super 3) s (super -1) and are all within the range of terrestrial observations. Therefore, the large leveed plains flows on Mars are not dramatically different in eruption rate or lava viscosity from large terrestrial analogs.

Petrological, geochemical and isotope (K-Ar, Sr and Nd) data were obtained in serpentinites, gabbros and andesite dykes from the Cabo de la Vela Mafic-Ultramafic Complex from the Guajira Peninsula, in the northernmost Colombian Caribbean region. Field relations, metasomatic alteration patterns and whole rock-mineral geochemistry combined with juvenile isotope signatures of the different units suggest that gabbros and serpentinites formed in a slow-spreading supra-subduction zone that was brought to shallower depths and subsequently evolved to an arc setting where andesitic rocks formed with little sediment input. The tectonomagmatic evolution of the Cabo de la Vela Mafic-Ultramafic Complex involved an intra-oceanic arc that evolved from pre-Campanian time to 74 Ma. Relationships with other units from the Guajira Peninsula show either the existence of a mature arc basement or a series of coalesced allocthonous arcs, juxtaposed before accretion onto the passive continental margin of South American in pre-Eocene times.

Coastal ecosystems support great biological productivity and are of immense ecological and economic importance. In addition, more than two-thirds of the human population resides in the coastal zone, where human activities cause chronic and acute disturbance of every habitat and marked degradation of ecological balance and productivity. The Chesapeake Bay and its Rhode River subestuary are used by SERC as model study systems to conduct long-term, intensive monitoring and experiments. Research at SERC focuses on five grand environmental challenges: (I) impacts of atmospheric change on climate, sea level, ultraviolet radiation, pollutant deposition, and carbon balance; (II) impacts of watershed nutrient discharges causing harmful algal blooms, depletion of oxygen, and destruction of submerged vegetation; (III) food web disruption by pollution and overfishing; (IV) invasive species; and (V) landscape disturbance by agriculture and development. Research by SERC on these grand challenges serves to advise policy and management from improved stewardship of coastal resources.

AN - 66909639; 19204334 AB - The health status of 83 loggerhead sea turtles (Caretta caretta; 39 foraging, 31 nesting, and 13 stranded turtles) was analyzed using physical examinations, hematology, plasma biochemistry, plasma protein electrophoresis, and toxicologic parameters. Significant differences were noted in a number of health parameters between turtles exhibiting each of these behaviors. On physical examinations, stranded turtles had the highest prevalence of heavy carapace epibiont loads, miscellaneous abnormalities, emaciation, and weakness. Differences in hematologic values included a lower packed cell volume, higher number of lymphocytes, and lower number of monocytes in stranded turtles; lower white blood cell counts in foraging turtles; and significant differences in total solid values among turtles exhibiting all behaviors with the lowest values in stranded turtles and the highest values in nesting turtles. Differences in plasma biochemistry values included the highest uric acid, creatine kinase, and CO(2) values in stranded turtles; the highest glucose and potassium values in foraging turtles; and the highest cholesterol and triglyceride values, and lowest alanine aminotransferase, in nesting turtles. Differences in total protein, albumin, and globulin were found using plasma biochemistry values, with lowest values in stranded turtles and highest values in nesting females, whereas differences in blood urea nitrogen between turtles included the lowest values in nesting turtles and the highest in foraging turtles. Plasma organochlorine and polychlorinated biphenyl levels were below their limits of quantification in the 39 foraging, 11 nesting, and three stranded turtles tested. A statistically significant difference was noted in the level of whole blood mercury between the 23 foraging and 12 nesting turtles tested. There was no difference in arsenic or lead levels between turtles exhibiting any of the three behaviors. Although a few limitations exist with the present study and include unknown ambient temperatures, turtle handling times that varied from 15 min to 53 min per turtle, and the use of a different laboratory for processing complete blood counts and plasma biochemistries in stranded versus foraging and nesting turtles, we provide baseline blood values for two cohorts (foraging and nesting) of loggerhead sea turtles on the coast of Georgia. Additionally, we demonstrate significant differences in clinical findings and blood parameters between foraging, nesting, and stranded loggerhead turtles in the region.

Progressive improvement in observational constraints on body tides, generated from both ground and space-based surveys, suggests that an examination of the potential impact of lateral variations in Earth structure is warranted. We present a suite of predictions of the body tide response within the semi-diurnal, diurnal and long-period tidal bands computed using a finite-volume numerical code. The calculations adopt 3-D density and elastic structure taken from seismic inferences and, in a subset of the calculations, dynamic topography on the surface and internal interfaces. We find that perturbations in the radial displacement and surface gravity within the semi-diurnal band reach nearly equal 1 mm and 0.15 mu gal, respectively. The perturbations in the diurnal band are comparable to these values, and within the long-period band they are a factor of 3-5 smaller. We also demonstrate that lateral variations in the elastic moduli, which have been ignored in recent work, contribute greater than 50% of the total perturbation. The level of perturbation associated with 3-D structure exceeds the current observational uncertainty obtainable using space-geodetic methods, and this suggests the possibility of performing tidal tomographic inversions of such data.

Following initial meteorite recoveries in 1976, the U.S. National Science Foundation, the National Aeronautics and Space Administration (NASA), and the Smithsonian Institution formed the U.S. Antarctic Meteorite program for the collection, curation, classification, and distribution of Antarctic meteorites, which was formalized in 1981. The Smithsonian provides classification and serves as the long-term curatorial repository, resulting in explosive growth of the Smithsonian meteorite collection. After 30 field seasons, more than 80% of the Smithsonian collection now originates from Antarctica. In addition to curation and classification, Smithsonian staff provide administrative leadership to the program, serve on field expeditions, and provide specimens for outreach and display. Given the relatively pristine state and ancient terrestrial ages of these meteorites, they provide perhaps our best sampling of the material in our solar system. Meteorites from the Moon were first recognized among the Antarctic meteorites in 1981, as was the first martian meteorite the next year. In 1996, debate erupted about evidence for past microbial life in an Antarctic martian meteorite, and that debate spurred the launch of two rovers to explore Mars. Among meteorites thought to have originated on asteroids, ingredients for ancient life may have survived much higher temperatures than previously envisioned during early planetary melting and differentiation. The ongoing collection of Antarctic meteorites will enrich the scientific community and Smithsonian Institution in specimens and knowledge about our solar system.

With its natural history and native cultures virtually unknown, Smithsonian Regents chartered a plan to investigate the most exciting questions posed by an unexplored continent at the dawn of the Darwinian era. Prominent issues included the origins and history of its aboriginal peoples, and this thirst for knowledge that led the young institution into America's subarctic and Arctic regions. The Yukon, Northwest Territories, and Alaska were among the first targets of Smithsonian cultural studies, and northern regions have continued to occupy a central place in the Institution's work for more than 150 years. Beginning with Robert Kennicott's explorations in 1858, Smithsonian scientists played a major role in advancing knowledge of North American Arctic and Subarctic peoples and interpreting their cultures. Several of these early enterprises, like the explorations, collecting, and research of Edward Nelson, Lucien Turner, John Murdoch, and Patrick Ray in Alaska and Lucien Turner in Ungava, either led to or were part of the first International Polar Year of 1882-1883. Early Smithsonian expeditions established a pattern of collaborative work with native communities that became a hallmark of the institution's northern programs. This paper presents highlights of 150 years of Smithsonian work on northern peoples with special attention to themes that contributed to Smithsonian Arctic studies during International Polar/Geophysical Year events, especially 1882-1883 and 2007-2008.

New institutions, such as the Office of Naval Research and the National Science Foundation, were established to fund basic science. Technological breakthroughs that had provided the instruments of war were recognized as having important economic, civilian applications. Understanding the earth's environment, including the extreme polar regions, the upper atmosphere, and the ocean depths, was recognized as key to enhancing a nation's communications, transportation, and commerce. The IGY developed in part from such national interests, but became a huge international undertaking. The process of international negotiations leading up to and during the IGY set a precedent for organizing cooperative scientific undertakings and enshrined norms and practices for sharing data and resources. Further, the IGY demonstrated the importance of communicating results across political, disciplinary, and societal boundaries. Fifty years later, the organizers of the International Polar Year embraced these values.

It functioned as a "national center for atmospheric research" in the nineteenth century and served as a model for the founding of the U.S. Weather Bureau. Its archives and collections document Smithsonian support and involvement over the years in many of the early weather and climate science initiatives: in both the first and second International Polar Years; in the founding of the Arctic Institute of North America and National Academy of Sciences Conference on the Antarctic; and in the International Geophysical Year in 1957-1958. This presentation examines the science, technology, and public opinion surrounding weather and climate research at both poles, from the middle of the nineteenth century through the first and second International Polar Years and the International Geophysical Year, up to the current International Polar Year 2007-2008.

Placing the first International Polar Year in the context of nineteenth-century scientific exploration and collaboration AN - 50402955; 2009-064588 AB - The first International Polar Year (IPY) of 1882-1883 came at the end of a half-century of efforts at collaborative and/or cooperative research among the scientific communities of Europe and the United States. These efforts included the Magnetic Crusade, a cooperative endeavor to solve fundamental questions in terrestrial magnetism; a variety of plans for international cooperation in the gathering of meteorological data; the observations of the transits of Venus; and the establishment of the Smithsonian's international network to alert astronomers of new phenomena. It was also a half century when scientific exploration of the polar regions was still problematic in terms of the safety and survival of the investigator. This paper will look at scientific cooperation and earlier Polar research as the background for the first IPY, with special emphasis on the leadership role taken by the Smithsonian Institution.

AN - 50402842; 2009-064595 AB - We summarize and evaluate explanations that have been proposed to account for the unusually high number of benthic marine invertebrate species in the Southern Ocean with nonpelagic development. These explanations are divided between those involving adaptation to current conditions in this cold-water environment, selecting for nonpelagic larval development, and those involving vicariant events that either exterminated a high proportion of species with pelagic development (the extinction hypothesis) or enhanced speciation in taxa that already had nonpelagic development. In the latter case, glacial maxima over the Antarctic Continental Shelf in the Pliocene/Pleistocene glacial cycles could have created refuges where speciation occurred (the ACS hypothesis), or the powerful Antarctic Circumpolar Current passing through Drake Passage for over 30 million years could have transported species with nonpelagic development to new habitats to create new species (the ACC hypothesis). We examine the distribution and phylogenetic history of echinoderms and crustaceans in the Southern Ocean to evaluate these different explanations. We could find little or no evidence that nonpelagic development is a direct adaptation to conditions in the Southern Ocean. Some evidence supports the three vicariant hypotheses, with the ACC hypothesis perhaps the best predictor of observed patterns, both the unusual number of species with nonpelagic development and the notably high biodiversity found in the Southern Ocean.

The first site is that of the Solomon A. Andree expedition camp on White Island, Svalbard. This fateful ballooning expedition to the North Pole in 1897 was the first experiment in polar aeronautics. Andree and his colleagues gave their lives but opened the door to polar flight, the backbone of polar logistics today. The other site, East Base, on Stonington Island off the Antarctic Peninsula, served the 1939-1941 U.S. Antarctic Service Expedition, under Admiral Richard Byrd, the first U.S. government-sponsored scientific and aerial mapping effort in Antarctica. In 1992, a team of archaeologists documented and secured the site that had been recently recognized as an historic monument by the Antarctic treaty nations. The third site is Marble Point on Victoria Land across from Ross Island and McMurdo Station. In conjunction with the IGY 1957-1958, a massive effort was put into laying out a 10,000-foot year-round runway and creating a fresh water reservoir and other base facilities. It was one of the premier locations for strategic aviation in Antarctica. The site was archaeologically surveyed and original engineering documentation from 1956-1957 offers superb baselines for studying permafrost, erosion, and human disturbances in the Antarctic environment. These types of sites are in situ monuments to human courage, ingenuity, and perseverance on a par with NASA's exploration of space. They require careful management and protection following the same principles as historic sites within the United States and in other nations.

AN - 50088178; 2010-017855 AB - Mars may possess a global sub-surface groundwater table as an integral part of its current hydrological system. However, the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) onboard the Mars Express (MEx) spacecraft has yet to make a definitive detection of such a body of liquid water. In this work, we quantify the conditions that would allow a detection of a deep aquifer and demonstrate that the lack of radar detection does not uniquely rule out the presence of such a body. Specifically, if the overlying crustal material has a conductivity above approximately 10 (super -5) S/m (equivalent to a loss tanget of 0.008), a radar echo from an aquifer could be sufficiently attenuated by the intervening medium to prevent its detection by MARSIS. As such, the lack of direct detection by MARSIS-a "null result"-does not rule out the possibility of the water table's existence.

Arthur Cooper and Richard E. Grant over decades of field work in the Permian Basin of western Texas provide a remarkable resource for studying change in the structure of fossilized ecological communities. Ordination analyses using 511 faunal lists that include 967 species (190 genera) from the Kungurian through the Capitanian Stages of the Guadalupe and Glass Mountains ( approximately 15 myr) reveal four distinct, major stratigraphic clusters, each divisible into two to three subclusters. For the most part, these clusters coincide with third-order depositional sequences bounded by unconformities. Except for the youngest (Capitanian Stage), all the stratigraphic clusters show internal ordination patterns consistent with biogeographic and environmental (i.e., biotic gradients) control on the distribution of taxa. Despite this evidence for environmental sorting of taxa, Mantel tests indicate that patterns of generic co-occurrence break down from cluster to cluster despite sharing many of the same species and genera. This pattern cannot easily be explained by preservational or stratigraphic biases, suggesting that the processes that govern ecological communities may not lead to unique, strictly determined associations despite the presence of broadly similar species under similar environmental conditions. In contrast to the rest of the study interval, Capitanian clusters are less well structured (i.e., they do not show strong biotic gradients) than assemblages from any of the other clusters and do not show significant recurrence of generic associations. This may reflect evolution of carbonate margins in the basin from ramps to shelves with steep slopes over the duration of the study interval, a shift that may have changed the spatial distribution of (and covariation among) the environmental parameters that controlled brachiopod distributions.

Images from the High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter (MRO) at 26á „52 cm/pixel scales reveal a >150-m sequence of exposed impact megabreccia and bedded sedimentary units in the crater. Crater walls display variably rounded, poorly sorted, chaotically arranged, and variably bright blocks up to 50 m across in a finer matrix. Some blocks may include sedimentary materials excavated from the pre-impact Holden basin, and all are interpreted as coarse, impact-fragmented megabreccia. Sedimentary strata above the megabreccia were emplaced during two wet phases in the ancient Noachian Period. Early prolonged erosion of crater walls and deposition in a quiescent distal alluvial or lacustrine setting on the crater floor formed a lower light-toned unit. The lower unit is topographically restricted and broadly distributed across the southern half of the crater. Lower unit beds are meter- to submeter-scale, traceable for up to kilometers, contain phyllosilicates, and few resolvable blocks. Later, shorter-lived flooding of the crater occurred as water impounded in Uzboi Vallis overtopped Holden's rim and emplaced an upper unit. The upper unit is topographically restricted, darker-toned, more crudely bedded, and unconformably drapes antecedent relief. The high magnitude of flooding associated with upper unit emplacement is confirmed by association with large fan deltas and bedforms incorporating meter-scale blocks and outcrops where blocks of eroded lower unit material up to 100 m across are enveloped. Upper unit morphology grades from alluvial near the crater rim breach to more continuously bedded, possibly lacustrine facies distally and upwards. These deposits record the more clement conditions and potential habitability of aqueous settings occurring on late Noachian Mars.

High Resolution Imaging Science Experiment (HiRISE) images (with resolutions to 25 cm/pixel) provide sufficient sampling across Martian aeolian features for the feature shape and dimensions to be derived from simple shape-from-shading (photoclinometry) techniques. Transverse Aeolian Ridges (TARs) on the floor of Ius Chasma on Mars are very similar to symmetric sand dunes at Coral Pink Sand Dunes (Utah, USA) on Earth when both the horizontal and vertical distances are normalized by the width of the feature (defined here to be the basal breaks in slope to either side of the feature crest). Ripple-like features, present in complex patterns around dark sand dunes on the floor of the Gamboa impact crater on Mars, are nearly identical to granule ripples at Great Sand Dunes (Colorado, USA) and in the Mojave Desert (California, USA) on Earth when dimensions are normalized by the feature width. Results obtained from HiRISE images examined to date suggest that, in general, Martian aeolian ridges 10 m in width (which includes most TARs) are most likely to be symmetric sand dunes.

We examined six tributary canyons (two branches of Bowns, Explorer, Fence, and two branches of a tributary between the latter two) in 2008 to evaluate the roles of seepage weathering and erosion relative to runoff in dissecting the Jurassic, aeolian Navajo sandstone. Collected data include Schmidt hammer measurements and Selby bulk strength of headwall rock; spring discharge, pH, and hardness; discharge estimates of flash flood channels; and relief profiles of canyon headwalls and alcoves. The contributing plateau contains mostly rounded slickrock, which yields abundant runoff relative to infiltration. Abrasion and standing water in potholes facilitate incision of narrow, V-shaped gullies into massive Navajo sandstone. These gullies funnel water over headwalls, often forming a small plunge pool at the base and removing headwall debris. Seeps near the contact between Navajo and underlying Kayenta fluvial sandstones and shales form broad alcoves in headwalls and are likely responsible for the box canyon's width relative to the contributing stream. Vertical differences in rock strength were not observed in the Navajo formation. Headwall retreat depends on waterfall attack at the base, weathering related to vegetation on the lower slope of the alcove, salt weathering on its roof, and sheet fracturing on unweathered scarps above the alcove. Flash floods of approximately 1-10 m (super 3) /s compare to spring discharges of 0.001-0.002 m (super 3) /s and are responsible for most sediment transport, including imbricated rocks up to tens of centimeters across. The box canyons grow headward along the contributing streams rather than the structural dip, and structural control by large tectonic joints was not observed. A hybrid model for theater-headed valleys in massive rocks includes seepage weathering and sheet fracturing at headscarps, with transport of debris by flash floods.

In addition, well-resolved molecular phylogeniesderived from these DNA barcode sequences have the potential to improve investigations of the mechanisms underlying communityassembly and functional trait evolution. To date, no studies have effectively applied DNA barcodes sensu strictu in this manner. In this report, we demonstrate that a three-locus DNA barcode when applied to 296 species of woody trees, shrubs, and palms found within the 50-ha Forest Dynamics Plot on Barro Colorado Island (BCI), Panama, resulted in >98% correctidentifications. These DNA barcode sequences are also used to reconstruct a robust community phylogeny employing a supermatrixmethod for 281 of the 296 plant species in the plot. The three-locus barcode data were sufficient to reliably reconstructevolutionary relationships among the plant taxa in the plot that are congruent with the broadly accepted phylogeny of floweringplants (APG II). Earlier work on the phylogenetic structure of the BCI forest dynamics plot employing less resolved phylogeniesreveals significant differences in evolutionary and ecological inferences compared with our data and suggests that unresolvedcommunity phylogenies may have increased type I and type II errors. These results illustrate how highly resolved phylogeniesbased on DNA barcode sequence data will enhance research focused on the interface between community ecology and evolution.

Here, we report on an similar to 58-my-old flora from the Cerrejon Formationof Colombia (paleolatitude similar to 5 AN) that is the earliest megafossil record of Neotropical rainforest. The flora has abundant, diverse palms and legumes and similar family composition to extant Neotropical rainforest. Three-quarters of the leaf typesare large and entire-margined, indicating rainfall >2,500 mm/year and mean annual temperature >25 AC. Despite modern familycomposition and tropical paleoclimate, the diversity of fossil pollen and leaf samples is 60-80% that of comparable samplesfrom extant and Quaternary Neotropical rainforest from similar climates. Insect feeding damage on Cerrejon fossil leaves, representing primary consumers, is abundant, but also of low diversity, and overwhelmingly made by generalist feeders ratherthan specialized herbivores. Cerrejon megafossils provide strong evidence that the same Neotropical rainforest families havecharacterized the biome since the Paleocene, maintaining their importance through climatic phases warmer and cooler than present.The low diversity of both plants and herbivorous insects in this Paleocene Neotropical rainforest may reflect an early stagein the diversification of the lineages that inhabit this biome, and/or a long recovery period from the terminal Cretaceousextinction.

A total of 30495 individuals from 87 species, 65 genera and 42 families were recorded. Of these 57 species of trees, 13 lianas, 12 shrubs and 5 large herbs were recorded. Species diversity as measured by Fisher's alpha was 11, stem density was 2652 stems ha super(-1) and basal area 59.4 m super(2) ha super(-1). Most species (67: 77%) were common (densities > 1 stem ha super(-1)), and widely distributed (36: 41%) among sholas. The Nilgiri sholas shared 34 (47%) species with Kukkal shola located in the Palni hills, 150 km south of the study site. This suggests a common biogeographical heritage. The unique shola forest is endangered and needs to be conserved on a priority basis.

This paper describes the detailed forensic methods and expertise used by the Smithsonian Institution's Feather Identification Lab to identify the bird that caused this bird-strike incident. We used standard methods of whole-feather analysis, microscopic examination, and DNA barcoding in this case to identify American white pelican (Pelecanus erythrorhynchos) as the bird species involved in this fatal crash. We also report the importance of proper field investigation and evidence collection for accurate results, particularly for this case, and generally for all bird-strike identifications.

Chromophoric dissolved organic matter is generally the main attenuator of UV radiation in the water column, and it affects the remote sensing of chlorophyll a (chl a) such that corrections for CDOM need to be incorporated into remote sensing algorithms. Despite its significance, relatively few CDOM measurements have been made in the open ocean, especially in polar regions. In this paper, we show that CDOM spectral absorption coefficients (al) are relatively low in highly productive Antarctic waters, ranging from approximately 0.18 to 0.30 mr super(-1) at 300 nm and 0.014 to 0.054 m super(-1) at 443 nm. These values are low compared to coastal waters, but they are higher (by approximately a factor of two to three) than al in oligotrophic waters at low latitudes, supporting the supposition of a poleward increase in a sub(CDOM) in the open ocean. Chromophoric dissolved organic matter al and spectral slopes did not increase during the early development of a bloom of the colonial haptophyte Phaeocystis antarctica in the Ross Sea, Antarctica, even though chl a concentrations increased more than one-hundred-fold. Our results suggest that Antarctic CDOM in the Ross Sea is not coupled directly to algal production of organic matter in the photic zone during the early bloom but is rather produced in the photic zone at a later time or elsewhere in the water column, possibly from organic-rich sea ice or the microbial degradation of algal-derived dissolved organic matter exported out of the photic zone. Spectral al at 325 nm for surface waters in the Southern Ocean and Ross Sea were remarkably similar to values reported for deep water from the North Atlantic by Nelson et al. in 2007. This similarity may not be a coincidence and may indicate long-range transport to the North Atlantic of CDOM produced in the Antarctic via Antarctic Intermediate and Bottom Water.

In particular, we characterize two ways to mitigate radiation trapping, a decoherence mechanism at high atomic density: nitrogen as buffer gas, and a long, narrow cell geometry. Initial results show the promise of both approaches in minimizing radiation trapping, but also reveal problems such as optical pumping into trapped end-states. We also observe distortion in EIT lineshapes at high optical depth, a result of interference from four-wave mixing. Experimental results are in good qualitative agreement with theoretical predictions.

We use phylogenetic comparative methods to examine evolutionary trade-offs associated with camouflage in the crab superfamily Majoidea. The majoids, or spider crabs, are known for their decoration behavior in which they attach materials from their environment to hooked setae on their carapace. We found that coverage of hooked setae on a crab (morphology) strongly predicts decoration cover in the field (behavior). Half of the species examined exhibited decreases in the coverage of hooked setae with ontogeny, and we also found a strong negative correlation between the extent of hooked setae and adult body size among species using independent contrasts, suggesting that size may constrain the evolution of camouflage. Finally, using a well-resolved clade of epialtids (kelp crabs)-many of which decorate little but use color change as an alternative camouflage strategy-we found a negative correlation between utilization of decoration versus color camouflage strategies. Our findings suggest that the costs of hook production and decoration maintenance and/or the lowered adaptive value of camouflage for larger species may limit the evolutionary distribution of decoration camouflage among the majoids.

AN - 20331034; 9013281 AB - Auritifolia waggoneri gen. et sp. nov. has compound leaves and is possibly a peltasperm, with venation similar to Comia Zalessky. The frond is once pinnate, >40 cm in length, with a short petiole, subopposite pinnae, increasing in size distally, terminating in two elongate pinnae. The petiole base is swollen. Fronds probably abscised upon senescence. Venation is three ordered, each higher order of progressively smaller diameter. Pinna midveins arise from the main rachis and give rise to secondary veins. Two types of tertiary veins are present. One type arises from the secondaries and forms fascicles; the other type is interfascicular and arises directly from pinna midveins. All tertiaries are of the same diameter. Tertiary veins dichotomize, anastomose, and may terminate in blind endings, so not all extend to the laminar margin. Laminae are amphistomatic. Monocyclic stoma are surrounded by five to six subsidiary cells. Epidermis and palisade parenchyma are uniseriate. Auritifolia is most similar to Comia in which the tertiaries lack anastomoses and blind endings and terminate at the laminar margin. The leaf architecture of Auritifolia differs significantly from that of Comia.

AN - 20296638; 8914726 AB - AbstractWhat factors limit ecosystem evolution? Like human economies, ecosystems are arenas where agents compete for locally limiting resources. Like economies, but unlike genes, ecosystems are not units of selection. In both economies and ecosystems, productivity, diversity of occupations or species and intensity of competition presuppose interdependence among many different agents. In both, competitive dominants need abundant, varied resources, and many agents' products or services, to support the activity and responsiveness needed to maintain dominance. Comparing different-sized land masses suggests that productivity is lower on islands whose area is too small to maintain some of the interdependences that maintain diversity, productivity and competitiveness in mainland ecosystems. Islands lacking the rare, metabolically active dominants that make competition so intense in mainland ecosystems are more easily invaded by introduced exotics. Studies of islets in reservoirs identify mechanisms generating these phenomena. These phenomena suggest how continued fragmentation will affect future 'natural' ecosystems.

Recently acquired data on the depth and age of 11 buried and/or submerged levels of human activity at seven ancient sites serve to calculate average annual rates of subsidence along the northern Nile Delta margin during the middle to late Holocene. Subsidence rates range from 0.9 to 4.3 mm/yr, varying irregularly from west to east along the northern delta coast, and averaging 62.5 mm/yr for 11 data points on the margin as a whole. Subsidence rate is directly related to thickness of sediment section, with highest values in the eastern part of Manzala lagoon and at coastal promontories of the Damietta and Rosetta branches. This, in large part, is a function of underlying sediment compaction plus sediment loading and readjustment of strata at depth. Short-term natural events such as earthquakes, tsunamis, Nile floods, and winter storm surges also serve as triggers of subsidence. An additional important factor is human activity, such as construction of large structures on water-saturated substrates. Most modern towns along this increasingly populous delta margin are located in low-lying vulnerable settings presently subject to subsidence, a phenomenon that warrants close monitoring and increased implementation of protective measures.

In this study, hatchling orientation was recorded during natural emergences at Pongara National Park, Gabon. This nesting beach is located close to both the capital of Gabon and a developing resort area, Pointe Denis. Under natural conditions most sea turtle hatchlings emerge at night and orient to the ocean by crawling away from dark, high silhouettes landward towards the bright, low seaward horizons. Artificial lights interfere with natural cues and disrupt hatchling orientation. The relative influence of artificial lights, logs and erosion were assessed on the nesting beach in Pongara National Park using a linear mixed model. We found that the attraction to artificial lights was higher than the effect of silhouette cues landward alone, but could be balanced by the simultaneous presence of the moon. Based upon these results, we recommend combining light management in the resort area to reduce the light pollution on the nesting beach and reinforcement of natural cues landward to minimize the effect of the remaining light pollution from the capital.

Unique mitochondrial lineages of Haemoproteus were recovered from an average of 1.3 host species (maximum = 3) and 1.2 host families (maximum = 3) while lineages of Plasmodium were recovered from an average of 2.5 species (maximum = 27) and 1.6 families (maximum = 9). Averaged within genera, lineages of both Plasmodium and Haemoproteus were constrained in their host distribution relative to random expectations. However, while several individual lineages within both genera exhibited significant host constraint, host breadth varied widely among related lineages, particularly within the genus Plasmodium. Several lineages of Plasmodium exhibited extreme generalist host-parasitism strategies while other lineages appeared to have been constrained to certain host families over recent evolutionary history. Sequence data from two nuclear genes recovered from a limited sample of Plasmodium parasites indicated that, at the resolution of this study, inferences regarding host breadth were unlikely to be grossly affected by the use of parasite mitochondrial lineages as a proxy for biological species. The use of divergent host-parasitism strategies among closely related parasite lineages suggests that host range is a relatively labile character. Since host specificity may also influence parasite virulence, these results argue for considering the impact of haematozoa on avian hosts on a lineage-specific basis.

Many samples were identified by macroscopic and or microscopic comparisons with bat specimens housed in the museum and augmented during the last 2 years by DNA analysis. Bat remains from USAF strikes during this period were received at the museum from 40 states in the United States and from 20 countries. We confirmed that 46% of the strikes were caused by bats, but we did not identify them further; we identified 5% only to the family or genus level, and 49% to the species level. Fifty-five of the 101 bat-strike samples submitted for DNA analysis have been identified to the species level. Twenty-five bat species have been recorded striking USAF planes worldwide. The Brazilian free-tailed bat (Tadarida brasiliensis; n = 173) is the species most commonly identified in USAF strike impacts, followed by the red bat (Lasiurus borealis; n = 83). Bat strikes peak during the spring and fall, with >57% occurring from August through October; 82% of the reports that included time of strike were recorded between 2100 and 0900 hours. More than 12% of the bat strikes were reported at >300 m above ground level (AGL). Although $825,000 and >50% of this sum was attributable to 5 bat-strike incidents. Only 5 bats from the 10 most damaging bat strikes were identified to the species level, either because we did not receive remains with the reports or the sample was insufficient for identification.

Responses to solar exposure of the phytoplankton and bacterial assemblages were studied aboard the research ice breaker Nathaniel B. Palmer during cruises NBP0409 and NBP0508. Photosynthesis and bacterial production (thymidine and leucine incorporation) were measured during in situ incubations in the upper 10 m at three stations, which were occupied before, during, and after the annual peak of a phytoplankton bloom dominated by Phaeocystis antarctica. Near-surface production was consistently inhibited down to 5-7 m, even when some surface ice was present. Relative inhibition of phytoplankton increased and productivity decreased with increasing severity of nutrient limitation as diagnosed using F sub(v)/F sub(m), a measure of the maximum photosynthetic quantum yield. Relative inhibition of bacterial production was high for both the high-biomass and postbloom stations, but sensitivity of thymidine and leucine uptake differed between stations. These results provide the first direct evidence that solar exposure, in particular solar ultraviolet radiation, causes significant inhibition of Ross Sea productivity. JF - Smithsonian at the Poles.

We employed an acid-hydrolysis-incubation method and a net nitrogen-mineralization assay to assess stability of soil carbon pools and short-term nitrogen dynamics in a Florida scrub-oak ecosystem after six years of exposure to elevated CO2. We found that soil carbon concentration in the slow pool was 27% lower in elevated than ambient CO2 plots at 0-10 cm depth. The difference in carbon mass was equivalent to roughly one-third of the increase in plant biomass that occurred in the same experiment. These results concur with previous reports from this ecosystem that elevated CO2 stimulates microbial degradation of relatively stable soil organic carbon pools. Accordingly, elevated CO2 increased net N mineralization in the 10-30 cm depth, which may increase N availability, thereby allowing for continued stimulation of plant productivity by elevated CO2. Our findings suggest that soil texture and climate may explain the differential response of soil carbon among various long-term, field-based CO2 studies. Increased mineralization of stable soil organic carbon by a CO2-induced priming effect may diminish the terrestrial carbon sink globally.

Consequently, the circumpolar distribution of krill has often been defined as generally limited to an area bounded by the maximum extent of pack ice. Pack ice has both direct and indirect effects on the Me cycle of krill. During the austral winter, larval krill are found in direct association with the underside of the ice and feed on the small plants and animals that constitute the sea ice microbial community, a food source relatively abundant in winter compared to food sources in the water column. Indirectly, melting pack ice in late winter or early spring stabilizes the water column and promotes growth of the preferred food of krill, which, in turn, likely provides the fuel for egg production during the summer months. Thus, the warming trend west of the Antarctic Peninsula with attendant changes in both the timing and duration of winter ice has implications for the population dynamics of krill. Given the complexity of the habitat-life cycle interaction, research on Antarctic krill involves diverse sampling tools that are dependent on the size and habitat of krill during a particular stage of their life cycle, and the nature of the study itself. In particular, and pertinent to the topic of diving in polar research, the research has been greatly enhanced by diving techniques developed to allow both observation and sampling of krill in their winter pack-ice habitat.

Available data suggest that a strong latitudinal pattern exists for such human introductions in coastal systems. The documented number of introduced species (with established, self-sustaining populations) is greatest in temperate regions and declines sharply at higher latitudes. This observed invasion pattern across latitudes may result from differences in (1) historical baseline knowledge, (2) propagule supply, (3) resistance to invasion, and (4) disturbance regime. To date, the relative importance of these mechanisms across geographic regions has not been evaluated, and each may be expected to change over time. Of particular interest and concern are the interactive effects of climate change and human activities on marine invasions at high latitudes. Shifts in invasion dynamics may be especially pronounced in the Northern Hemisphere, where current models predict not only an increase in sea surface temperatures but also a rapid reduction in sea ice in the Arctic.

Perry's contributions to meteorite collection and research, 1927-1957 AN - 1473594013; 2013-006185 AB - Stuart H. Perry (1874-1957), an influential Michigan newspaper editor and publisher and a vice president of the Associated Press, developed a passionate interest in collecting and studying meteorites in the 1920s and 1930s. Firmly believing that meteorites belong in great museums where they can be properly investigated, he generously donated his meteorites to various museums after he finished his own study of them. He had a sincere interest in the National Collection of Meteorites, and donated 192 specimens--mostly irons--to the U.S. National Museum; these constituted some of the most important meteorites in its collection, and moved iron meteorites to center stage, a position still occupied. By applying current metallographic methods to the study of iron meteorites, Perry directed scientists to a powerful new research tool, which led to major advances in our understanding of meteoritic irons and helped give rise to a new field within planetary sciences. His groundbreaking monograph The metallography of meteoric iron served as a standard reference collection of metallographic photomicrographs of iron meteorites for more than 30 years. It remained an insightful and useful work on the structure of meteoritic iron until improved binary and ternary phase diagrams in the Fe-Ni(-P) system allowed a more detailed treatment of the formation of iron meteorites. Perry received many honors for his work, and held office in the Meteoritical Society, serving as a councilor from 1941-1950, and as a vice president from 1950-1957.

During the Early Cretaceous, the basal ceratopsian Psittacosaurus was among the most common dinosaurs in Asia but more derived basal neoceratopsians were quite rare on that continent (Xu et al. 2002; Makovicky and Norell 2006). Basal neoceratopsians became more abundant in the Late Cretaceous of Mongolia and China, although they are not known in this region from the latest Cretaceous (You and Dodson 2004; Alifanov 2008). In contrast, basal neoceratopsians are rare during the Early Cretaceous in North America but became common and diverse during the Campanian and Maastrichtian (You and Dodson 2004; Chinnery and Horner 2007). Little is known about the evolutionary history of this group in more inland regions of what are now Kazakhstan and adjoining countries. Asiaceratops documents the presence of basal neoceratopsians in the Cenomanian of Uzbekistan (Nessov et al. 1989). Here we report on the first record of a basal neoceratopsian in the Late Cretaceous of Kazakhstan, based on two cranial bones from the Turonian Zhirkindek Formation in the northeastern Aral Sea region.

HABs have been associated with human illnesses through the contamination of fish and shellfish with a range of biotoxins. The economic impacts can be measured in the millions of dollars, severely affecting marine fisheries and aquaculture in many countries. Management strategies, therefore, are vital to minimize or prevent the health effects and financial losses associated with HABs. This chapter examines strategies for bloom mitigation, focusing on controlling the organisms. Some common methods will be reviewed, e.g. chemical control, and some new and emerging strategies will be presented and discussed. JF - Shellfish safety and quality.

It is generally thought that during the Late Miocene Panama was comprised of a volcanic arc archipelago and that by the end of the Miocene it had merged into a single land mass. Yet the exact manner in which the Isthmus of Panama emerged and eventually closed, the exact tectonic motions that drove that closure and the evolution of sedimentary basins in response to tectonic change is not well understood. We use correlations of Miocene to Pliocene aged stratigraphic, paleocurrent, petrographic, and geochemical data from samples collected from across Panama to reconstruct the evolution of fluvial drainage networks and carbonate and siliciclastic basins evolving in response to the emerging Cenozoic Panama Cordillera. We in turn use this data together with paleobotanical data to constrain the timing and 3D geometry of uplift and subsidence in the Panama Block.

Examination of 75 males and 58 females from this collection revealed elevated levels of dental caries, antemortem tooth loss, and alveolar abseesses suggesting dietary preferences conducive to dental disease without sufficient dental hygiene. A low frequency of dental hypoplasia suggests low childhood morbidity. Comparative data from elsewhere in Europe and the Americas indicate that the dental disease in 19th century Spain was elevated but similar to that found in other regions at the time.

We report here an examination of starch grains preserved in the calculus of human teeth from these sites that provides direct evidence for the early consumption of cultivated squash and peanuts along with two other major food plants not previously detected. Starch from the seeds of Phaseolus and Inga feuillei, the flesh of Cucurbita moschata fruits, and the nuts of Arachis was routinely present on numerous teeth that date to between 8210 and 6970 super(14)C yr B.P. Early plant diets appear to have been diverse and stable through time and were rich in cultivated foods typical of later Andean agriculture. Our data provide early archaeological evidence for Phaseolus beans and I. feuillei, an important tree crop, and indicate that effective food production systems that contributed significant dietary inputs were present in the 'anchoc region by 8000 super(14)C yr B.P. Starch grain studies of dental remains document plants and edible parts of them not normally preserved in archaeological records and can assume primary roles as direct indicators of ancient human diets and agriculture.

10318970 AB - Traits associated with seed dispersal vary tremendously among sympatric wind-dispersed plants. We used two contrasting tropical tree species, seed traps, micrometeorology, and a mechanistic model to evaluate how variation in four key traits affects seed dispersal by wind. The conceptual framework of movement ecology, wherein external factors (wind) interact with internal factors (plant traits) that enable movement and determine when and where movement occurs, fully captures the variable inputs and outputs of wind dispersal models and informs their interpretation. We used model calculations to evaluate the spatial pattern of dispersed seeds for the 16 factorial combinations of four traits. The study species differed dramatically in traits related to the timing of seed release, and a strong species by season interaction affected most aspects of the spatial pattern of dispersed seeds. A rich interplay among plant traits and seasonal differences in atmospheric conditions caused this interaction. Several of the same plant traits are crucial for both seed dispersal and other aspects of life history variation. Observed traits that limit dispersal are likely to be constrained by their life history consequences.

However, pollen from closely related individuals in the local neighbourhood might reduce fruit set or increase fruit abortion in self-incompatible tree species. We investigated the role of neighbourhood density and genetic relatedness on individual fruit set and abortion in the neotropical tree Jacaranda copaia in a large forest plot in central Panama. Using nested neighbourhood models, we found a strong positive effect of increased conspecific density on fruit set and maturation. However, high neighbourhood genetic relatedness interacted with density to reduce total fruit set and increase the proportion of aborted fruit. Our results imply a fitness advantage for individuals growing in high densities as measured by fruit set, but realized fruit set is lowered by increased neighbourhood relatedness. We hypothesize that the mechanism involved is increased visitation by density- dependent invertebrate pollinators in high-density populations, which increases pollen quantity and carry-over and increases fruit set and maturation, coupled with self-incompatibility at early and late stages due to biparental inbreeding that lowers fruit set and increases fruit abortion. Implications for the reproductive ecology and conservation of tropical tree communities in continuous and fragmented habitats are discussed.

Recruitment and mortality of large individuals ( greater than or equal to 10cm diameter-at-breast-height) were recorded within 21 1-ha plots in fragmented and intact forests for periods of up to 22years. In addition, 12 small (0.714m) sub-plots within each 1-ha plot were used to enumerate the abundance of seedlings and saplings (5-400cm tall). On average, the recruitment of large trees was over two times faster near forest edges, leading to a sharp (90%) increase in the mean population density of large individuals near forest edges, whereas the density of larger trees remained constant in the forest interior. Overall seedling and sapling density was significantly lower in edge than interior plots, but edge plots had a much higher proportion of larger (>100cm tall) saplings. Our findings demonstrate that forest edges can have complex effects on tree demography and that one must consider all tree life stages in order to effectively assess their effects on plant populations.

The Smithsonian effort was a direct collaborative effort of the libraries, archives, museums, and information technology staff that generated new pathways for collaboration between these units. As the world's largest museum complex, these Smithsonian units serve as a microcosm for collaboration in the information age. The Flickr Commons project provided insights into how the knowledge, skills, and abilities of libraries, archives, and museums (LAM) can converge in the Web 2.0 environment to provide collection access to new, and in some cases unknown, audiences. Simultaneously, by putting "LAM" content into an environment that allows for direct interaction by these audiences, the knowledge of the content for holding institutions is enriched. By exposing Smithsonian content within the Flickr environment, the Institution is learning what content is desired by the Web 2.0 world, how to bring crowd-sourcing into professionally curated collections, and how to bring diverse institutional skills together in a collaborative project.

Herein is described the new balistid Gornylistes prodigiosus gen. et sp. nov. from the uppermost Middle Eocene (Kuma Horizon) of the Northern Caucasus (Gorny Luch locality); it is as thoroughly modern in its bauplan as the taxa of balistids from the Oligocene and more recent periods, and far more advanced morphologically than the several stem taxa of the balistoid + ostracioid clade known from earlier in the Middle and Lower Eocene and from the Upper Paleocene.

On the basis of data for 11 whole-rock samples plus 124 glass inclusions and olivine host crystals, we evaluate a vein-wallrock melting relationship between the lamprophyres (vein-dominated melts) and the mafic calc-alkaline rocks (diluted by partial melting of peridotite wall-rock after exhaustion of phlogopite and other vein minerals). Whole-rock Fe (super 3+) /Fe (super 2+) and glass-inclusion %S (super 6+) indicate relatively high fO (sub 2) in these magmas, up to several log units above the Ni-NiO buffer. The highest concentrations of water and most other volatile elements (7% H (sub 2) O, 1460 ppm CO (sub 2) , approximately 2% SO (sub 3) (super Total) , 2400 ppm Cl, and approximately 1% F) were recorded for a glass inclusion from a Colima minette with 48.2 wt % SiO (sub 2) , 6.0 wt % K (sub 2) O, and 1.2 wt % P (sub 2) O (sub 5) (normalized anhydrous). This sample's volatile composition corresponds to a depth of entrapment of 24 km (calculated pressure of 6660 bars). This inclusion (trapped within olivine with Mg-number 91.5) represents the most primitive melt in this study and has a composition that can be attributed to partial melting of phlogopite-pyroxenite veins in the mantle wedge with minor dilution (possibly as little as approximately 25%) by partial melts from the surrounding peridotite wall-rock. However, there are indications that even this inclusion has undergone degassing, suggesting that primary vein melts have even higher H (sub 2) O and CO (sub 2) contents. Further dilution of the vein-dominated lamprophyre melts by wallrock melts yields basanites and ultimately calc-alkaline basalts. Mafic calc-alkaline whole-rock and glass-inclusion compositions are consistent with formation through mixing of approximately 5% vein melts with approximately 95% peridotite wallrock melt. Among the calc-alkaline glass inclusions the Mascota basaltic andesite has the highest concentrations of water and most other volatile elements with 49.6 wt % SiO (sub 2) , 1.0% K (sub 2) O, 0.3% P (sub 2) O (sub 5) (normalized anhydrous), 2.8% H (sub 2) O, 296 ppm CO (sub 2) (1425 bars pressure and 5.2 km depth of entrapment), 0.8% SO (sub 3) (super Total) , 870 ppm Cl, and 720 ppm F. Such mafic calc-alkaline melts are envisioned as parental to the volumetrically dominant andesites of western Mexico.

Authors are recommended to avoid using the term 'allotype' for specimens other than paratypes." The Glossary in the next edition of the Code should change accordingly. This is to assure that allotypes always have unequivocal status as paratypes and, thus, are covered by Recommendation 75A as potential reserve name-bearers. Only type specimens should bear the root 'type'.

Technology is essentially the prime enabler that allows sustainable fashion to thrive and develop today. The role of technology within the sustainable fashion realm is broken into two main areas: the physical manifestation of sustainable fashion garments, including textiles, and the digital domain. The effects of technology in sustainable fashion are best understood through looking at the work of a technology theoretician, Andrew Feenberg, who advocates for small, but effective, 'democratic rationalizations' of technology to achieve positive change.

He critiques my dissertation work, yet I neither conducted butchery experiments nor attempted to interpret cut marks at FLK Zinj. His hypothesis that the presence of cut marks on upper or 'meaty' limb elements (and especially midshafts of these meaty limb elements) is a zooarchaeological signal of hominin early access to carcasses is based in part on observations of flesh yield on felid kills. My research is relevant because my observations increase the range of variation in flesh yield of abandoned felid kills and document variability in intra-limb patterns of flesh distribution. Dominguez-Rodrigo's approach to Early Pleistocene hominin carcass acquisition and/or processing strategies must take this variability into account.

AN - 21266027; 11721888 AB - Over the past two decades, the combination of molecular and field methods has revealed considerable variation in the level of extrapair fertilizations among socially monogamous birds. Models predicting extrapair young range in scale from a single population to multiple Orders, and there is no single, unifying theory for these reproductive tactics. We investigated proximate explanations of extrapair fertilizations in two subspecies of the swamp sparrow, Melospiza georgiana georgiana and Melospiza georgiana nigrescens, across a range of social and environmental conditions. The presence of extrapair young was best predicted by the size of two male plumage badges (one correlated with parental care and one with territorial aggression) relative to the badge size of their immediate neighbors, the interaction of these two measures, mean territory size, and the maximum size of the aggression badge among neighbors. The size of the male's parental care badge (relative to neighbors) was negatively correlated with the probability of lost paternity. The relative size of the aggression badge was positively correlated with the presence of extrapair young when the parental care badge was small and negatively correlated when the badge was large. Controlling for these crown measures, males with larger territories were less likely to suffer losses in paternity. There was no effect of breeding density, breeding synchrony, their interaction, subspecies, or weather during the fertile period on the presence of extrapair young. These results suggest that female preference for males that provide more parental care (or preference for genes that convey this trait) plays a dominant role in extrapair interactions among swamp sparrows. Models based on female assessments of relative mate quality offer a promising explanation of patterns in extrapair fertilizations among bird species.

Despite being relatively depauperate in species richness, the clade contains four taxa typically accorded ordinal status: Actinulida, Limnomedusae, Narcomedusae and Trachymedusae. We bring molecular data (mitochondrial 16S and nuclear small and large subunit ribosomal genes) to bear on the question of phylogenetic relationships within Trachylina. Surprisingly, we find that a diminutive polyp form, Microhydrula limopsicola (classified within Limnomedusae) is actually a previously unknown life stage of a species of Stauromedusae. Our data confirm that the interstitial form Halammohydra sp. (Actinulida) is derived from holopelagic direct developing ancestors, likely within the trachymedusan family Rhopalonematidae. Trachymedusae is shown to be diphyletic, suggesting that the polyp stage has been lost independently at least two times within trachyline evolution. Narcomedusae is supported as a monophyletic group likely also arising from trachymedusan ancestors. Finally, some data, albeit limited, suggest that some trachyline species names refer to cryptic species that have yet to be sorted taxonomically.

The agroforestry system can serve as a source of non-coffee products for diverse purposes. This study focuses on the role of shade trees in smallholder coffee farms, examining the wood products derived from the shaded coffee system. Data presented from surveys with 185 growers in Peru and 153 growers in Guatemala show that the consumption and sale of all non-coffee products account for a fifth to a third of the total value realized from the agroforestry system. Fuelwood and construction materials account for much of this value. Differences seen between countries can be traced to agricultural intensification - the degree to which the coffee agroforestry system is ''technified'' (i.e., managed with a reduced shade tree cover and diversity, high-yielding cultivars, agrochemical inputs, etc.) - as well as the relative demand for wood resources and farmers' access to natural forest systems.

Four subspecies are recognized within C. crocodilus, suggesting some geographic variation in morphology. In this study, we utilized mitochondrial DNA (mtDNA) sequence data from 45 individuals of C. crocodilus throughout its range to infer its evolutionary history and population structure, as well as to evaluate genealogical support for subspecies and their geographic distributions. Our molecular phylogenetic results identified five mtDNA haplotype clades with a mean sequence divergence of 3.4%, indicating considerable evolutionary independence among phylogeographic lineages. Our results were also broadly consistent with current subspecific taxonomy, with some important additional findings. First, we found substantial genetic structuring within C. c. fuscus from southern Mesoamerica. Second, though we confirmed the existence of a widespread Amazonian clade, we also discovered a cryptic and divergent mtDNA lineage that was indistinguishable from C. c. crocodilus based on external morphology. Third, we confirm the status of C. c. chiapasius as a distinct evolutionary lineage, and provide evidence that C. c. fuscus may be moving northward and hybridizing with C. c. chiapasius in northern Mesoamerica. Finally, our results parallel previous phylogeographic studies of other organisms that have demonstrated significant genetic structure over shorter geographic distances in Mesoamerica compared with Amazonia. We support conservation efforts for all five independent lineages within C. crocodilus, and highlight the subspecies C. c. chiapasius as a unit of particular conservation concern. J. Exp.

We evaluated the impacts of a wide gradient of disturbance in Gabon on a range of arthropod assemblages representing different feeding guilds. We examined 4 105 arthropod individuals from which 21 focal taxa were separated into 1534 morphospecies. Replication included the understory of 3 sites in each of 4 different stages of forest succession and land use (i.e., habitats) after logging (old and young forests, savanna, and gardens). We used 3 complementary sampling methods to survey sites throughout the year. Overall differences in arthropod abundance and diversity were greatest between forest and open habitats, and cleared forest invaded by savanna had the lowest abundance and diversity. The magnitude of faunal differences was much smaller between old and young forests. When considered at this local scale, anthropogenic modification of habitats did not result in a monotonous decline of diversity because many herbivore pests and their associated predators and parasitoids were abundant and diverse in gardens, where plant productivity was kept artificially high year-round through watering and crop rotation. We used a variety of response variables to measure the strength of correlations across survey locations among focal taxa. These could be ranked as follows in terms of decreasing number of significant correlations: species turnover > abundance > observed species richness > estimated species richness > percentage of site-specific species. The number of significant correlations was generally low and apparently unrelated to taxonomy or guild structure. Our results emphasize the value of reporting species turnover in conservation studies, as opposed to simply measuring species richness, and that the search for indicator taxa is elusive in the tropics. One promising alternative might be to consider 'predictor sets' of a small number of taxa representative of different functional groups, as identified in our study. Cambios en Ensambles de Artropodos a lo largo de un Gradiente de Perturbacion Amplio en GabonResumen:La busqueda de taxa indicadores representativos de ensambles diversos, como lo artropodos, es un objetivo importante de muchos estudios de conservacion. Evaluamos los impactos de un gradiente de perturbacion amplio en Gabon sobre ensambles de artropodos representando gremios alimentarios diferentes. Examinamos 4 105 individuos de artropodos de los cuales 21 taxa focales fueron separados en 1534 morfoespecies. La replicacion incluyo el sotobosque de tres sitios en cada una de cuatro etapas diferentes de la sucesion de bosques y de uso de suelo (i.e., habitats) despues de ser talados (bosques jovenes y maduros, sabana y jardines). Utilizamos tres metodos de muestreo complementarios para estudiar los sitios a lo largo del ano. Las diferencias generales en la abundancia y diversidad de artropodos fueron mayores entre bosques y habitats abiertos, y el bosque talado invadido por sabana tuvo la menor abundancia y diversidad. La magnitud de las diferencias fue mucho mas pequena entre los bosques maduros y viejos. Al considerarla en esta escala local, la modificacion antropogenica de habitats no resulto en una declinacion monotona de la diversidad porque muchas plagas de herbivoros y sus depredadores y parasitoides asociados fueron abundantes y diversas en los jardines, donde la productividad de plantas fue mantenida artificialmente a lo largo del ano mediante riego y rotacion de cultivos. Utilizamos una variedad de variables de respuesta para medir la robustez de las correlaciones en los sitios de muestreo entre taxa focales. Estos pudieron ser clasificados, en terminos del numero decreciente de correlaciones significativas, como sigue: renovacion de especies > abundancia > riqueza de especies observada > riqueza de especies estimada > porcentaje de especies especificas de sitios. El numero de correlaciones significativas generalmente fue bajo y aparentemente sin relacion con la taxonomia ni la estructura del gremio. Nuestros resultados enfatizan el valor de reportar la renovacion de especies en los estudios de conservacion, en lugar de simplemente medir la riqueza de especies, y que la busqueda de taxa indicadores es elusiva en los tropicos. Una alternativa prometedora pudiera ser la consideracion de 'conjuntos pronosticadores' de numeros pequenos de taxa representativos de grupos funcionales diferentes, como los identificados en nuestro estudio.

We use previous information on the webs of 88 species and new data on the web designs of 78 additional theridiid species (representing nearly half of the theridiid genera), and 12 other species in related families. Two strong, surprising patterns emerged: substantial within-taxon diversity; and frequent convergence in different taxa. These patterns are unusual: these web traits converged more frequently than the morphological traits of this same family, than the web traits in the related orb-weaving families Araneidae and Nephilidae, and than behavioural traits in general. The effects of intraspecific behavioural 'imprecision' on the appearance of new traits offer a possible explanation for this unusual evolutionary plasticity of theridiid web designs.

The main study objective was to determine base line health values for free-ranging turtles and to compare results from free-ranging (i.e., foraging and nesting) and stranded turtles. Biomaterials were collected from nesting and foraging turtles in conjunction with on-going ecological studies and all turtles were tagged at the time of sampling. Samples were collected from stranded turtles as part of the clinical evaluation to determine prognosis and therapeutic needs of the turtle. Samples collected from all turtles included blood, feces and epibiota from live animals, as well as complete necropsies and tissue preservation from eggs, hatchlings and adult turtles that were found freshly dead or euthanized. Additionally, physical examinations were conducted on all live caught turtles. Laboratory analyses of blood samples included hematology, plasma chemistries and protein electrophoresis. Blood toxin levels were determined for a subset of live captured turtles and histopathologic evaluations were conducted on tissues and toxin levels were determined for dead turtles. These data are not presented in this talk.

After five decades of decline, the total forest cover increased by 0.36% yr super(-1) between 1992 and 2000; however, mature forest cover simultaneously decreased by 1.3% yr super(-1). This limited forest transition at the national scale comprised two distinctly different patterns of recent forest-cover change related to historical land use. Districts that were largely deforested when the first national survey of forest cover was completed in 1947 experienced a strong forest transition between 1992 and 2000. In these, the proportion of the population employed in agriculture decreased by an average of 31% and natural secondary forest succession increased the total forest cover by an average of 85% between 1992 and 2000. In contrast, no forest transition was evident for districts that were largely forested in 1947. In these, the absolute number of people employed in agriculture remained constant, old-growth forest cover decreased by 8% on average, and natural secondary forest succession increased, so that the total forest cover tended to be static between 1992 and 2000. Historical land use, an index of human poverty, and the population density of agricultural workers explained 61% of the among-district variation in forest cover in 2000, with forest concentrated in areas where populations were small and poor. Historical land use and gross income per hectare from agriculture explained 23.5% of the among-district variation in forest-cover change between 1992 and 2000. The early history of forest loss, an uneven distribution of people, and disparities in farm income contributed to the limited forest transition observed in Panama.

We obtained DNA sequences from museum specimens of Moho and Chaetoptila collected in Hawaii 115-158 years ago. Phylogenetic analysis of these sequences supports monophyly of the two Hawaiian genera but, surprisingly, reveals that neither taxon is a meliphagid honeyeater, nor even in the same part of the songbird radiation as meliphagids. Instead, the Hawaiian species are divergent members of a passeridan group that includes deceptively dissimilar families of songbirds (Holarctic waxwings, neotropical silky flycatchers, and palm chats). Here we designate them as a new family, the Mohoidae. A nuclear-DNA rate calibration [9] suggests that mohoids diverged from their closest living ancestor 14-17 mya, coincident with the estimated earliest arrival in Hawaii of a bird-pollinated plant lineage [10]. Convergent evolution, the evolution of similar traits in distantly related taxa because of common selective pressures, is illustrated well by nectar-feeding birds [11], but the morphological, behavioral, and ecological similarity of the mohoids to the Australasian honeyeaters makes them a particularly striking example of the phenomenon.

The genus comprises multiple species that are endemic to New Guinea and were presumed to belong to the family Pachycephalidae or Colluricinclidae, within the core corvoidea, an ancient Australasian radiation of crow-like birds. In order to understand the evolution of toxicity within the genus Pitohui, we sequenced three mitochondrial and two nuclear gene segments and reconstructed a phylogeny of the genus Pitohui and its putative relatives. We show that the genus Pitohui is polyphyletic, and consists of five different lineages. Using Bayesian ancestral state reconstruction, we estimate that toxicity likely evolved multiple times within this group. Furthermore, because the morphological and behavioral similarity among these poisonous birds appears to have evolved convergently, we hypothesize that this may be a possible example of Muellerian mimicry in birds. The Morningbird of Palau, Micronesia, that has often been included in the genus Pitohui, actually belongs in the genus Pachycephala and offers an intriguing case of pronounced evolution on a remote oceanic island.

Two genera are new: Bathypurpurinopsis has a fusiform shell with a siphonal fold, and variable Paskentana has turbiniform or littoriniform shells with spiral and/or scaly sculpture and convex or shouldered whorls. Due to the lack of data on shell microstructure and protoconch morphology, many of our taxonomic assignments have to remain tentative at present. Species that are described as new include: Hokkaidoconcha bilirata, H. morenoensis, H. tehamaensis (Hokkaidoconchidae), Abyssochrysos? giganteum (Abyssochrysidae?), Paskentana globosa, P. berryessaensis, and Bathypurpurinopsis stantoni (Abyssochrysoidea, family uncertain). The total fauna represents a mixed bag of taxa that were: (i) widely distributed during the late Mesozoic (Amberleya); (ii) restricted to late Mesozoic seep carbonates in California (Atresius, Bathypurpurinopsis, Paskentana); and (iii) members of seep/deep-sea groups with a long stratigraphic range (abyssochrysids, hokkaidoconchids).

Although the family is diverse in tropical America today, most araceous fossils, however, have been recorded from middle and high latitudes. Here, we report fossil leaves of Araceae from the middle-late Paleocene of northern Colombia, and review fossil araceous pollen grains from the same interval. Two of the fossil leaf species are placed in the new fossil morphogenus Petrocardium Herrera, Jaramillo, Dilcher, Wing et Gomez-N gen. nov.; these fossils are very similar in leaf morphology to extant Anthurium; however, their relationship to the genus is still unresolved. A third fossil leaf type from Cerrejon is recognized as a species of the extant genus Montrichardia, the first fossil record for this genus. These fossils inhabited a coastal rainforest approximately 60-58 million years ago with broadly similar habitat preferences to modern Araceae.

8832980 AB - In this paper the immature stages of Brenthia monolychna Meyrick (Choreutidae: Brenthiinae), as well as their ul-trastructure, are described and figured. This is the first description of a New World brenthiine. In addition, notes on life history for four New World species of Brenthia Clemens are provided, including mention of their host plants and parasitoids. Host plant utilization of the genus is discussed. A clarification of the nomenclature of the longest seta on the larval abdominal segment 9 is proposed. Earlier literature disagrees on whether this is a lateral, subdorsal, or dorsal seta - my examination suggests it is the subdorsal seta 1. The recorded distribution of Brenthia pavonacella Clemens is questioned, and a revised distribution is suggested. Moreover, an escape mechanism, employed by all known Brenthia larvae, is discussed. Finally, a list of morphological and behavioral synapo-morphies for the subfamily Brenthiinae and the genus Brenthia is provided.

Recent, higher resolution images have revealed another, morphologically distinct, large population of smaller, ripple-like aeolian bedforms that have been termed "Transverse Aeolian Ridges" (TARs) as it is unknown whether they formed as large ripples or small dunes. We have begun a new study of TARs that examines their distribution, orientation, and morphology using >10,000 high-resolution Mars Orbiter Camera (1.5 to 8 m/pixel resolution) images in a 45 degrees longitude wide, pole-to-pole survey. The aim of this study is to assess whether TARs are active, to identify possible sediment sources and pathways, and to determine the volumes of sediment that they comprise. We present results from the first half of this study, in which we examine the northern hemisphere, and describe a new three-part classification scheme used to aid the survey. Our results show that TARs are abundant but not ubiquitous: preferentially forming proximal to friable, layered terrains such as those found in Terra Meridiani - the location of the ongoing Mars Exploration Rover "Opportunity" mission. TAR distribution in the northern hemisphere shows a strong latitudinal dependence with very few TARs being found north of nearly equal 30 degrees N. We also find that in most cases TARs are less mobile than LDDs, a conclusion possibly explained by Mars Exploration Rover Opportunity observations that show TAR-like ripples to have a core of fine material armored by a monolayer of granule-sized particles. This could disallow significant bedform movement under the current wind regime. That TARs are essentially inactive is confirmed by superposition relations with slope streaks and LDDs and by observations of superposed impact craters. We suggest that observations made by the Opportunity Rover in Terra Meridiani indicate that the small aeolian bedforms common here are ripples and not small dunes. Farther south, these bedforms transition into larger features indistinguishable from TARs, suggesting that TARs (in the Meridiani area at least) are ripples and not dunes.

Diatoms are common in much of the sequence and preserve a record of environmental change within the basin. A high-resolution diatom stratigraphy has been developed for these deposits. The data document the presence of freshwater and saline lakes as well as wetlands. Transfer functions indicate that these water bodies ranged in conductivity between about 200-20,000 mu S cm (super -1) , with pH varying between about 7.5 and 10.3. Pedogenesis affected multiple horizons within the succession, reflecting periods of emergence that encompass much of the time represented by the Olorgesailie formation. A variety of other sedimentological indicators (carbonates, rhizoliths, mudcracks, erosional channels) also record periods when the sampled portions of the basin were dominated by terrestrial conditions. Stone tools are common at several levels, indicating the use of the area by hominins. Lakes and wetlands were potentially usable as sources of potable water by hominins for part of the basin history, but at other times were undrinkable. Other water sources (springs, rivers) would have been necessary during these periods. Paleoenvironments in the basin were complex and changed frequently with time. Such shifts in resources and habitat distribution during Olorgesailie Formation time seem likely to have influenced the behavior and evolution of local plant and animal populations, including Homo.

These opals do not show play-of-color, but are valued in the gem market for their intrinsic body color. Common opal-AG and opal-CT are primarily built from nanograins that average approximately 25 nm in diameter. Only opal-AN has a texture similar to that of glass. In opal-AG, nanograins arrange into spheres that have successive concentric layers, or in some cases, radial structures. Common opal does not diffract light because its spheres exhibit a range of sizes, are imperfectly shaped, are too large or too small, or are not well ordered. Opal-AG spheres are typically cemented by non-ordered nanograins, which likely result from late stage fluid deposition. In opal-CT, nanograins have different degrees of ordering, ranging from none (aggregation of individual nanograins), to an intermediate stage in which they form tablets or platelets, to the formation of lepispheres. When the structure is built of lepispheres, they are generally cemented by non-ordered nanograins. The degree of nanograin ordering may depend on the growth or deposition rate imposed by the properties of the gel from which opal settles, presumably, fast for non-ordered nanograin structures in opal-CT to slow for the concentric arrangement of nanograins in the spheres of opal-AG.

We measured water concentration profiles around spherulites in obsidian by synchrotron Fourier transform infrared spectroscopy. The distribution of OH (super -) groups surrounding spherulites decreases exponentially away from the spherulite-glass border, reflecting expulsion of water during crystallization of an anhydrous paragenesis (plagioclase+SiO (sub 2) +clinopyroxene+magnetite). This pattern is controlled by a balance between the growth rate of the spherulites and the diffusivity of hydrous solute in the rhyolitic melt. We modeled advective and diffusive transport of the water away from the growing spherulites by numerically solving the diffusion equation with a moving boundary. Numerical models fit the natural data best when a small amount of post-growth diffusion is incorporated in the model.

AN - 50450474; 2009-040236 AB - Neoproterozoic Palaeogeographic reconstructions of Rodinia conventionally place the western (Proto-Andean) margin of Amazonia against the eastern (Appalachian) margin of Laurentia. Separation and formation of the Iapetus Ocean is generally considered to have occurred later at nearly equal 550 Ma. We examine the U-Pb detrital zircon "fingerprint" of autochthonous rocks from the northern and central segments of the Proto-Andean margin, which formed part of the western margin of Amazonia during the Late Neoproterozoic-Phanerozoic. The Proto-Andean margin is clearly the most feasible source region for most of the zircon grains, except for a 550-650 Ma sub-population, broadly age-equivalent to the Brasiliano/Pan-African Orogeny in eastern Amazonia. No obvious source for this detritus is known in the northern and central Andes. Derivation from eastern Amazonia is considered unlikely due to the stark paucity of detritus derived from the core of the Amazonian craton. Instead, we propose that a Late Neoproterozoic magmatic belt is buried beneath the present-day Andean belt or Amazon Basin, and was probably covered during the Eocene-Oligocene. If this inferred Neoproterozoic belt was an active margin, it would record the initiation of Proto-Andean subduction and imply at least partial separation of West Gondwana from its conjugate rift margin of eastern Laurentia prior to ca. 650 Ma. This separation may be linked to the ca. 770-680 Ma A-type magmatism found on eastern Laurentia in the southern Appalachians, and on the Proto-Andean margin in the Sierra Pampeanas and the Eastern Cordillera of Peru.

Satellite images and Differential Global Positioning System (DGPS) survey data, along with observations and photographs from the field, are combined to provide a new perspective on the 1907 eruption. Boundaries of the flow field from the satellite data, combined with field measurements of flow thickness, indicate an area of 25.1 km (super 2) and a volume of 86.6 million m (super 3) . The eastern lobe of the flow field covers an area of 13.1 km (super 2) , with a volume of 55.0 million m (super 3) , and was emplaced with an average effusion rate of 119 m (super 3) /s (at least, for the upper portion of the lobe). Ten DGPS topographic profiles across the eastern lobe aid in distinguishing the characteristics of, and transitions between, the zones identified during the emplacement of the 1984 Mauna Loa flow. Several subdivisions have been built directly on top of or adjacent to the 1907 lava flow. The strong likelihood of future eruptions from the Mauna Loa southwest rift zone makes these housing developments of particular importance for assessments of potential volcanic hazards.

We provide a video and data showing that these larvae, when their webs are disturbed, shoot through their wormhole to the opposite side of the leaf at extremely high speeds: the fastest caterpillar passed through to the opposite leaf surface in only 100ms. Experimental data show that Brenthia larvae use their silken web shelters as an extension of their sensory system. Although such usage of webbing is not surprising given what is known about spider webs, this is the first time such a behaviour has been shown to occur in Lepidoptera. Two grossly hypertrophied abdominal setae, directed behind the body, are not pulled through the wormhole, but instead remain intercalated into the silken lattice of the web shelter. By leaving the two setae engaged, the caterpillar is able to monitor both sides of its host leaf simultaneously. We report analogous escape hole behaviours in four other microlepidopteran families: Elachistidae, Gelechiidae, Oecophoridae and Pyralidae. In at least one genus of the latter family (Monoloxis), two caudally directed abdominal setae are hypertrophied in the same fashion as in Brenthia. We suspect that both escape holes and hypertrophied abdominal setae are more common and taxonomically widespread than presently recognized and that both 'strategies' will be shown to occur among other microlepidopterans.

Two core transects provide new information on the Holocene history of related reef systems off the northeastern coast of St. Croix --- the outer shelf-edge reef complex ranging from northern Lang Bank through Buck Island Bar and ending at Long Reef, and the inner bank-barrier reef off Tague Bay. The outer shelf-edge reef system records progressively shallower and thinner marginal reef initiation and development above a westward-shallowing Pleistocene substrate; this surface rises from -15 m at Buck Island Bar to -6 m MSL at Long Reef. The core transect through the inner bank-barrier reef at Tague Bay reveals a 10-m thick accumulation of an Acropora palmata-dominated reef framework on a well developed 12-15 m deep erosional terrace. A sea-level analysis for northeastern St. Croix indicates three periods in which different areas were the foci of reef initiation and development. The timing of initiation of reef systems along these reef trends as sea level rose during the Holocene follows the slope of the Pleistocene surface as it rises to the west, with the oldest (easternmost) reefs forming on the deepest areas of the antecedent topography. The westernmost reefs were initiated later as sea level reached the slightly higher elevations of the antecedent surfaces in these areas. The timing of Holocene reefs at these two sites is a direct result of the interaction of sea-level rise, antecedent topography, shelf erosion and evolving environmental conditions affecting coral health. The unique reef history at Buck Island Bar represents a particular case whose relationship to the Caribbean Holocene sea-level record supports paleoenvironmental interpretations potentially impacting all of Lang Bank to the east.

The direct effects of WNV on avian hosts include documented population declines, but other, indirect ecological consequences of these changed bird communities, such as changes in seed dispersal, insect abundances, and scavenging services, are probable and demand attention. Furthermore, climate (seasonal precipitation and temperature) and land use are likely to influence the intensity and frequency of disease outbreaks, and research is needed to improve mechanistic understanding of these interacting forces. This article reviews the growing body of research describing the ecology of WNV and highlights critical knowledge gaps that must be addressed if we hope to manage disease risk, implement conservation strategies, and make forecasts in the presence of both climate change and WNV-or the next emergent pathogen.

We selected trees in medium elevation wet forests (750-1700 m asl) of the southern WG, using two data bases: a small plot (30 30 m) data base of 288 species of trees ( greater than or equal to 3 cm dbh) in 33 plots totaling 2.97 ha, and a data base of 135 species of tree ( greater than or equal to 10 cm dbh) in larger plots of 1 ha each, totaling 4.84 ha. The species density per hectare and number of records in the plot network was used in a factor analysis to give a measure of the local abundance of each species. The altitude and seasonality ranges of these species in the WG was assessed from independent data bases and used to generate an environmental tolerance score. Results indicated that as a species became locally more abundant, it occurred across a wider range of environmental gradients, but regional distribution was not related to geographical distribution. Understory species tended to be rarer with smaller range sizes and lower environmental tolerances than overstory species. Climate change is predicted to have drastic effects on restricted range species with limited environmental tolerances.

However, evidence of endocrine disruption in wild amphibians living in agricultural areas has been controversial. Typically, studies on the effects of pollutants on wildlife attempt to compare polluted with unpolluted sites. Objectives: We took a novel approach to address this question by explicitly quantifying the relationship between gonadal abnormalities and habitats characterized by differing degrees of agricultural activity. Methods: We quantified the occurrence of gonadal abnormalities and measures of gonadal function in at least 20 giant toads (Bufo marinus) from each of five sites that occur along a gradient of increasing agricultural land use from 0 to 97%. Results: The number of abnormalities and frequency of intersex gonads increased with agriculture in a dose-dependent fashion. These gonadal abnormalities were associated with altered gonadal function. Testosterone, but not 17b-estradiol, concentrations were altered and secondary sexual traits were either feminized (increased skin mottling) or demasculinized (reduced forearm width and nuptial pad number) in intersex toads. Based on the end points we examined, female morphology and physiology did not differ across sites. However, males from agricultural areas had hormone concentrations and secondary sexual traits that were intermediate between intersex toads and non-agricultural male toads. Skin coloration at the most agricultural site was not sexually dimorphic; males had female coloration. Conclusions: Steroid hormone concentrations and secondary sexual traits correlate with reproductive activity and success, so affected toads likely have reduced reproductive success. These reproductive abnormalities could certainly contribute to amphibian population declines occurring in areas exposed to agricultural contaminants.

We carried out two screened growing-house experiments with seedlings of Gustavia superba (Lecythidaceae) to test hypotheses proposed to explain why cotyledons are retained. We grew seedlings from large and small seeds in sun and shade to determine if cotyledon reserves supplement photosynthetic carbon gain, and in a second experiment applied defoliation and shoot removal treatments to determine if reserves are allocated to resprout tissue. In each experiment we tracked cotyledonary resource use over time and measured the fraction of seedling biomass allocated to roots and shoots. We found no evidence that light environment, seed size or damage treatment affected the rate of cotyledon resource usage; 20% of the cotyledonary mass remained 9 wk after leaves were fully developed in both sun and shade and 25-30% of the cotyledonary mass remained 6 wk after leaf or shoot removal. Instead, cotyledon reserves appear to be slowly translocated to roots regardless of light environment or seedling damage. Once seedlings are established, lost tissue is replaced using reserves stored in roots; in high light, damaged seedlings had a lower root mass fraction (0.42) than undamaged ones (0.56) when considering the mass of tissue removed and resprout tissue combined. We conclude that cotyledon reserves are important for resprouting during early seedling emergence and establishment, but do not directly contribute to seedling growth or biomass recovery from herbivores at the post-establishment stage. Persistence of cotyledons may ultimately depend on the development of sufficient root mass for reserve reallocation.

Seeds of both species were either scarified, to represent seed condition after dispersal by terrestrial birds, or left intact, to represent seed condition after dispersal by arboreal birds. Seeds were distributed along forest transects, and germination, seedling development and mortality were monitored to determine the successes of the two groups at producing seedlings. Scarified seeds germinated with the early rains of the dry-to-wet-season transition, when erratic rainfall was interspersed with long dry spells. Intact seeds germinated 30 d later when the rain was more plentiful and regular. Intact seeds of O. macrocalyx gave rise to significantly more seedlings (41.1% vs. 25.5%) than did scarified seeds, in part, because significantly more seedlings from scarified seeds (n = 20) than from intact seeds (n = 3) died from desiccation when their radicles failed to enter the dry ground present during the dry-to-wet-season transition. Also, seedlings from scarified seeds were neither larger nor more robust than those from intact seeds despite their longer growing period. Results are consistent with the hypothesis that dispersal effectiveness of arboreal birds, at least for O. macrocalyx, is greater than that of terrestrial birds. Screen-house experiments in which seedlings developed under different watering regimes supported this result. Numbers of seedlings developing from intact and scarified seeds of O. bopiensis did not differ significantly.

Sites with concentrated sea turtle nesting were compared with solitary nesting sites as a function of place and time based on ANOVA, Akaike's Information Criterion, and Bayesian analyses. Results indicate that sea turtle egg mortality was significantly associated (P < 0.005) with flowing water that erodes or saturates nesting sites, and with overlapped nesting in which sea turtles disturb each other's nests. Sarcophagid and calliphorid fly larvae (Bayesian prior = 1.19; posterior = 2.27), fungi (prior = 1.14; posterior = 1.92), mites (prior = 0.51; posterior = 1.15), and several other types of small organisms increased in number after turtle egg laying (N= 303 nests; 34,451 turtle eggs). During peak sea turtle nesting periods, visitation to nesting sites by poachers and vertebrate predators was high, and relative number of nests disturbed by these predators was low (P < 0.02). In multimodel analysis, the three most parsimonious models were: (1) turtle egg mortality and distance from mean high tide; (2) turtle egg predation and distance from mean high tide; and (3) turtle egg mortality and nesting density, with Akaike weights of 0.224, 0.203, and 0.153 respectively. Intensive sea turtle nesting might result in upwelling and turnover of nesting debris and nest organisms, and may influence biotic community structure of sandy beach ecosystems.

This article presents a synthesis of the patterns and possible causes of alpha species diversity variation in benthic deep-sea ostracodes at drilling sites in the North Atlantic and Arctic Oceans. Taken together, these sites represent a period of great climatic variability covering the past three million years. Sediment cores taken from the Mid-Atlantic Ridge show a positive correlation between warm temperatures and high species diversity. These Mid-Atlantic Ridge cores, at the same latitude as northern Spain, show the same positive correlation during the last two glacial-interglacial cycles (200-0 ka [thousands of years ago]) as they do during the pre-glacial Pliocene 2.85-2.4 Ma (millions of years ago). This positive correlation is also found in Pliocene cores from the Rockall Plateau, at the same latitude as Ireland. During the last 200 thousand years, however, this correlation is reversed in cores taken from both the Rockall and Iceland Plateaus. The discovery of high diversity during colder periods in recent high-latitude Rockall and Iceland cores seems to be explained by spikes in diversity caused by ice-rafting events, which would not affect the lower-latitude Mid-Atlantic Ridge. The Heinrich ice-rafting events reduce North Atlantic surface temperatures and salinity every 66-12 ka, dramatically decreasing surface productivity. This increase in diversity during Heinrich events may be explained either by a negative correlation between surface productivity and benthic diversity or by increase in diversity caused by moderate disturbance when ice rafted debris fall to the bottom of the ocean.

Here we review how application of recent phylogenetic methods, genomics and evo-devo approaches is changing our view of Dollo's Law and its underlying mechanisms. Phylogenetic studies have recently demonstrated cases where seemingly complex features such as digits and wings have been reacquired. Meanwhile, large genomics databases and evo-devo studies are showing how the underlying developmental pathways and genetic architecture can be retained after the loss of a character. With dwindling evidence for the law-like nature of Dollo's Law, we anticipate a return to Dollo's original focus on irreversibility of all kinds of changes, not exclusively losses.

The purpose of this study was to assess the geographic pattern in the abundance, species richness, and importance of different migration patterns of the boreal forest avifauna of Eurasia from Europe to East Asia as well as their relationship to climate and forest productivity. We further examine data from two widely separated sites in the New World to see how these conform to the patterns found in the Eurasian system. LocationBoreal forest sites in Russia and Canada. MethodsPoint counts were conducted in two to four boreal forest habitats at each of 14 sites in the Russian boreal forest from near to the Finnish border to the Far East, as well as at two sites in boreal Canada. We examined the abundance and species richness of all birds, and specific migratory classes, against four gradients (climate, primary productivity, latitude, and longitude). We tested for spatial autocorrelation in both dependent and independent variables using Moran's I to develop spatial correlograms. For each migratory class we used maximum likelihood to fit models, first assuming uncorrelated residuals and then assuming spatially autocorrelated residuals. For models assuming unstructured residuals we again generated correlograms on model residuals to determine whether model fitting removed spatial autocorrelation. Models were compared using Akaike's information criterion, adjusted for small sample size. ResultsOverall abundance was highest at the eastern and western extremes of the survey region and lowest at the continent centre, whereas the abundance of tropical and short-distance migrants displayed an east-west gradient, with tropical migrants increasing in abundance in the east (and south), and short-distance migrants in the west. Although overall species richness showed no geographic pattern, richness within migratory classes showed patterns weaker than, but similar to, their abundance patterns described above. Overall abundance was correlated with climate variables that relate to continentality. The abundances of birds within different migration strategies were correlated with a second climatic gradient - increasing precipitation from west to east. Models using descriptors of location generally had greater explanatory value for the abundance and species-richness response variables than did those based on climate data and the normalized difference vegetation index (NDVI). Main conclusionsThe distribution patterns for migrant types were related to both climatic and locational variables, and thus the patterns could be explained by either climatic regime or the accessibility of winter habitats, both historically and currently. Non-boreal wintering habitat is more accessible from both the western and eastern ends than from the centre of the boreal forest belt, but the tropics are most accessible from the eastern end of the Palaearctic boreal zone, in terms of distance and the absence of geographical barriers. Based on comparisons with Canadian sites, we recommend that future comparative studies between Palaearctic and Nearctic faunas be focused more on Siberia and the Russian Far East, as well as on central and western Canada.

We conducted dung surveys within the Gamba Complex of Protected Areas in SW Gabon to examine (1) the feasibility of noninvasive faecal analyses for monitoring stress physiology, and (2) the influence of petroleum operations on stress levels in forest elephants. LocationGabon, Central Africa. MethodsWe identified multiple dung piles from the same individual by matching their eight-locus microsatellite genotypes, and measured faecal concentrations of glucocorticoid metabolites as an indicator of stress in areas subject to different levels of disturbance: (1) Loango National Park (2) an 'industrial corridor' dominated by oil fields, and (3) a nearby area of human settlements. ResultsWe obtained unique microsatellite genotypes and faecal glucocorticoid metabolite (FGM) concentrations for 150 forest elephant individuals, which is the largest hormonal data set for wild African forest elephants to date. Adults exhibited higher mean FGM concentrations than juveniles, and in contradiction of our expectations of chronic stress around oil fields, elephants in Loango National Park exhibited significantly higher FGM concentrations than elephants in the industrial corridor. Main conclusionsWe argue that forest elephants in the industrial corridor of the Gamba Complex have become acclimated to oil fields, resulting in part from oil company regulations that minimize stressful interactions between elephants and petroleum operations. Our findings for a flagship species with substantial ecological requirements bode well for other taxa, but additional studies are needed to determine whether oil operations are compatible over their life span with rain forest ecosystems in Central Africa.

A multi-approach study and a review of sexual systems in Hippolyte shrimps AN - 19309742; 8598082 AB - Sexual systems vary considerably among caridean shrimps and while most species are gonochoric, others are described as sequential protandric hermaphrodites or simultaneous hermaphrodites with an early male phase. At present, there is confusion about the sexual system exhibited by several species mostly because those studies attempting to reveal their sexual system draw inferences solely from the distribution of the sexes across size classes. Here we investigated the sexual system of the shrimp Hippolyte williamsi from Chile to determine if the species is protandric or gonochoric with sexual dimorphism (males smaller than females). Morphological identification and size frequency distributions indicated that the population comprised small males, small immature females, and large mature females, which was confirmed by dissections. No transitional individuals were found. Males maintained in the laboratory molted 1-8 times, and many grew up to reach sizes observed in only a small fraction of males in the field. No indication of sex change was recorded. Our results indicate that H. williamsi is a sexually dimorphic gonochoric species and emphasizes the importance of using several kinds of evidence (size measurements, growth experiments, morphological dissections, and histological studies) to reveal the sexual system of Hippolyte species. Whether the observed size dimorphism between males and females in many species of Hippolyte is expression of contrasting sexual and natural selection, and whether divergent sexual fitness functions can contribute to the evolution of hermaphroditism remains to be revealed in future studies.

Thomas, 1891 is a phyllostomid commonly called the Brazilian big-eyed bat. A brown bat with striking facial and dorsal stripes, it is the 2nd largest of the 5 species in the genus Chiroderma. It is endemic to southeastern Brazil with a single record from bordering Paraguay. C. doriae occurs in Atlantic Rain Forest, as well as in a variety of primary and secondary forests and even occasionally in urban parklands. It apparently specializes on wild figs. C. doriae is classified as vulnerable.

Using "glassy" preservation (preservation where there is no apparent test recrystallization at the submicron scale) as a criterion for evaluating delta (super 18) O results has greatly improved confidence in absolute paleotemperature estimates. However, data remain sparse for the Cretaceous. Further, existing data come largely from short intervals with unusual lithologic and faunal characteristics. These unusual characteristics raise the possibility that the results reflect temperatures or seawater compositions that were not typical for the time. Our new Tanzanian samples address these concerns. They contain a diverse assemblage of "glassy" planktic and benthic foraminifera preserved in otherwise unremarkable outer shelf claystones and silty claystones, and they span most of the Turonian (Whitinella archaeocretacea through Helvetoglobotruncana helvetica Zones). Additional samples from the Cenomanian, Coniacian, and Campanian are being processed. Our calculated paleotemperatures are several degrees lower than some Cretaceous tropical estimates but are still approximately 6 degrees C higher than summer seawater temperatures in comparable modern settings. Reproducing such temperatures in global climate models using Cretaceous boundary conditions requires atmospheric CO (sub 2) concentrations of 2500 ppm or more (almost 10x pre-industrial CO (sub 2) concentrations), a 10- to 20-fold increase in atmospheric methane combinations, or some combination of the two. These CO (sub 2) levels are higher than most estimates for the Cretaceous atmosphere supporting the conclusion that sensitivity to greenhouse gas forcing, at least on long time scales, is too low in the current climate models.

At both sites the relative abundance and diversity of large, ornamented taxa increases upsection consistent with warming and greater surface stratification through the Maastrichtian. In addition, the more offshore, deeper site (1050) contains distinct meter-scale cyclic variations in the relative abundance of many taxa that varies in parallel with cyclic variations in sediment color, stable isotopic values, and mineralogy. Cycles are effectively absent at the more shoreward, shallower site (1052), and the assemblages at Site 1052 are close to one end of the range of cyclic variability seen in similar-aged samples from Site 1050. Patterns of abundance among Heterohelix spp. (relatively abundant onshore and in the higher productivity portions of the offshore cycles) and Globotruncana spp. (relatively abundant in the low productivity portions of the offshore cycles) are particularly notable. A number of other taxa show consistently higher relative abundances in either the nearshore (e.g., Archaeoglobigerina) or offshore (e.g., Rugoglobigerina) site. Combined with previously documented onshore-offshore trends among nannofossil taxa, these observations are interpreted as indicating that Site 1052 was shoreward of a western boundary current while this current flowed near or over Site 1050 through most the Maastrichtian. The apparent proximity of the current to Site 1050 through time despite the considerable paleoceanographic changes that occurred during the Maastrichtian argues that some permanent feature (e.g., local bathymetry) acted to anchor the position of the current.

Such a peak should be identified by differential weathering conditions before and after the MMCO. Clay mineralogical analysis can be used as a marker of climatic conditions, as different clay minerals are formed depending on the prevailing precipitation and temperature values. Sedimentary sequences within the Culebra and Cucaracha Formations of the Panama Canal basin may contain the record of this peak. The Culebra Formation consists of mostly carbonaceous mudstones at the bottom and towards the top the amount of sandstone increases. The Cucaracha Formation is composed of reddish to grayish mudstone and claystone representing paleosols with some conglomerates and tuffaceous layers. Its depositional environment is interpreted as a deltaic plain with fluvial channels, mangroves, and flood plains. The contact between Culebra and Cucaracha Formations is abrupt, easily recognizable by a color change, it is of regional extent, and could be used to unravel stratigraphic relations in the Panama Canal basin. This study represents an untried approach to pinpoint the MMCO in the tropics, using clay mineralogy to infer paleoclimates. The advantage of using this technique in the Panama Canal basin is that the source areas are homogeneous--basic and intermediate rocks--and the thickness of the sedimentary pile is less than 1000m, thus having minimal diagenetic processes. Additionally, a detailed stratigraphy and sandstone modal analyses will be carried out. Age constraints will be assessed using U/Pb in zircons from tuff layers in the Cucaracha Formation, further calibrated with a palynological zonation.This study will provide an additional data source that may improve understanding of the Middle Miocene Climatic Optimum in the Neotropics.

Serpentinite melanges on both sides of the Motagua Fault (MF) contain rocks that record subduction, collisions and complex translations. Interpreting this geology is important for our understanding Caribbean Plate evolution. Serpentinite melange, north of the MF, hosts eclogite, garnet amphibolite, omphacite-taramite metabasite, jadeitite, albitite distributed over >200 km E-W. Garnet-clinozoisite amphibolites, in the east, have Cpx and Amph inclusions in garnet in a matrix of amphibole, clinozoisite and late stage albite, quartz, and chlorite. Rare omphacite in garnet suggests a prior history with eclogite at P > 1.2 GPa. More abundant Amph and Cpx inclusions and Gln argue reequilibration at approximately 1 GPa. Grt-Cpx pairs yield temperature of 500-550 degrees C whereas Amph-Grt pairs give 400-500 degrees C. Altered clinozoisite amphibole-eclogite to the west record a moderate LT eclogite facies of 500-600 degrees C at 1.5-2.0 GPa from Grt-Cpx pairs and paragonite + clinozoisite in the assemblage. A wide range of matrix alteration assemblages record greenschist-blueschist at lower T and P (300-400 degrees C at < or =1 GPa). In contrast, serpentinite melange, south of the MF, hosts lawsonite eclogite, blueschist, and jadeitite and records P-T conditions that require very deep and cold subduction to approximately 2.5 GPa at only 470 degrees C (Tsujimori et al. 2006). The P-T-t south of the Motagua Fault shows a simple VHP/LT trajectory followed by blueschist alteration during exhumation. A higher T and somewhat lower P maximum was achieved north of the fault, followed by a discrete grt-czo-amphibolite recrystallization event that was more pronounced toward the east. These interpretations are consistent with a distinct approximately 130 Ma peak metamorphic age (event) for all eclogites with a second event of 70-55 Ma north of the MF, probably related to a second collision.

The restoration and management of tidal wetlands may allow such areas to sequester carbon, helping to mitigate global warming, while the accumulation of organic materials may help prevent the marshes from being inundated by rising sea levels. We are sampling and monitoring soils on a natural marsh and a marsh restored in 2003 with locally derived dredged materials to determine organic matter accumulation rates, quantify carbon sequestration, and estimate accretion rates. Samples were collected in 2006 and 2007. The emissions of methane, a potent greenhouse gas, are also being monitored. This research is being performed in collaboration with the National Aquarium in Baltimore and the USGS Patuxent Wildlife Research Center.

In widely separated areas, irrespective of floral province and climatic zone, the abundance of pollen types reflects a strong decline of woody gymnospermous vegetation. The paleobotanical record indicates that the dieback of dominant gymnosperms was a global event that dramatically affected terrestrial ecosystems. Several typical Late Permian taxa, such as the Glossopteridales of Gondwanaland, the Cordaites of Angaraland, as well as a variety of Euramerican, Cathaysian and Angaran conifers, became extinct. A period of lycopsid and seedfern domination followed. In Europe, ecosystem recovery to precrisis levels of structure and function took 4 to 5 million years. Based on recent literature, the floral sequence of events following the end-Permian biotic crisis will be described using palynological and paleobotanical records.

Vegetation regrowth is rapid upon attaining hillslope stability and pasture abandonment, respectively, and apt to affect soil hydrology via changes in soil structure, a sensitive indicator of which is soil saturated hydraulic conductivity (K (sub s) ). Our objective was to quantify the influence of these regionally widespread and important disturbances on K (sub s) and the subsequent recovery of K (sub s) , and to describe the resulting spatial patterns. In a 2 km (super 2) large research area in southern Ecuador, we used a mixed design- and model-based sampling strategy for measuring K (sub s) in situ at soil depths of 12.5, 20, and 50 cm (n=30-150/depth) under landslides of different ages (2 and 8 years), under actively grazed pasture, fallows following pasture abandonment (2-25 years of age), and under natural forest, and for elucidating its spatial patterns. Global means of soil permeability generally decrease with increasing soil depth. K (sub s) does not differ among landslides and in comparison to the natural forest, which suggests a marginal effect of the regional landslide activity on soil hydrology. In contrast, results from the human-induced disturbance regime show a permeability decrease of two orders of magnitude after forest conversion to pasture at shallow soil depths, and a slow regeneration after pasture abandonment that requires a recovery time of at least one decade. Disturbances affect the K (sub s) spatial structure, in particular the correlation length, in the topsoil. The largest differences in the covariance parameters, however, are found for the subsoil K (sub s) , where the spatial structure is independent of land cover. This case study suggests a rather disparate soil hydraulic response to regionally important disturbances. Cattle grazing strongly affects the spatial mean of K (sub s) , whereas landslides do not, and both the processes affect the spatial structure of K (sub s) in the topsoil.

A unique methodology is required for rover studies, where methodology is defined as how, when, in what order and in what priority, instruments are used to answer scientific questions. Four years of rover operation on Mars using the Mars Exploration Rovers served as our template to test whether such a method of remote geology will optimize science return from a lunar rover mission. To test methodology, no rover mock-up or science instruments were used. Instead, at each site we broke down observational "days" into detailed analysis of three targets of interest (drive time was ignored). Images mimicking a multispectral high-resolution stereo imager and a handlens-scale imager were taken using a professional SLR digital camera with interchangeable lens capability and megapixel imaging, coupled with a macro lens. Following data collection and analysis, the field team examined each site using traditional terrestrial field methods, facilitating comparison between what was revealed by human versus rover-inspired methods. Preliminary results show that the benefits of the handlens as a convenient, effective triage tool are unavailable using current rover-driven methodology because handlens-type imagers cannot be deployed or used frequently. As such, it may be more effective to pursue ways to increase the number of handlens-scale images that can reasonably be taken and downlinked by a lunar rover. Also, characteristics diagnostic of the origin or evolution of a site must be plentiful and obvious for current methodology to be fully effective. More images at intermediate-scales would provide crucial contextual information in this regard. Future lunar rover missions might include dedicated rapid, low-power targeting imagers, or explicitly design field methods around the use of navigational instruments as lower-power options for targeting.

This increase was followed by sudden warming of approximately 5 degrees C at the PETM. The late Paleocene warming has been correlated to the mid-Tiffanian through Clarkforkian land mammal biozones through radiometric dating and magnetic polarity stratigraphy (Secord et al. 2006). Tiffanian through Clarkforkian floras from the Bighorn Basin of Wyoming demonstrate warming in the interior of North America coincident with that in the marine oxygen isotope record. Reconstruction of mean annual temperatures by leaf margin analysis shows a rise from approximately 10 degrees C in the late Tiffanian to approximately 12 degrees C in the early Clarkforkian to 15 degrees C in the late Clarkforkian. The same method implies a further increase to 20 degrees C during the PETM. It is interesting that the magnitude of late Paleocene warming in Bighorn Basin leaf margin analyses is approximately twice the magnitude recorded by the marine oxygen isotope record, even though the magnitude of warming at the PETM is the same in both records. This may reflect a true difference between the northern Rockies and the global record, or indicate that the leaf margin percentage increased in response to drying as well as warming. There is independent evidence from paleosols that parts of the Bighorn Basin were becoming better drained during this interval. Floral turnover during the late Tiffanian and Clarkforkian is characterized by a large number of first appearances, a few of which are long-ranging taxa that remain in the region throughout the early Eocene.

This mid-Paleozoic event was surpassed by the expansion of modern types of herbivory during Phase 2 in the late Paleozoic, ending with the end-Permian extinctions. Recovery after the extinction aftermath constitutes the third major phase of herbivory expansion, commencing modestly during the Middle Triassic in Laurasian and Gondwanan localities and reaching its acme during the Late Triassic in the Molteno Formation of South Africa's Karoo Basin. Our preliminary analyses of this abundant, diverse and well preserved biota--representing 106 stratigraphically ordinated localities, 7 geographically widespread habitats, 79 diagnostic insect/mite damage types (DTs), about 220 whole-plant taxa, and 177,301 examined leaf, seed, stem, and other organ specimens--has established the best fossil-record case for testing hypotheses of how plant and insects associate and evolve in deep time. From Molteno data, the following questions will be addressed: Do stereotyped plant-insect associations or combinations of associations characterize particular plant hosts and their habitats? Do dominant plant taxa and their herbivore component communities, evidenced by their DT spectra, evolve within habitats or among habitats? Is there gradual replacement of generalized DTs by host-specific DTs, perhaps accompanied by the partitioning of tissues within plant organs and the colonization of new plant taxa? What insect herbivore clades dominated this exceptional diversification onto horsetail, fern, and seed-plant host clades 90 m.y. before the angiosperm appearance that characterized the fourth major phase of herbivore expansion? Such questions will be addressed by a several million-year-old, internally well resolved, basin-wide record that will provide tests of hypotheses developed from modern plant-insect associational theory. We will document the timing, interspecies associations, autecological and synecological scope, and community structure of plant-insect associations during this circumscribed interval of deep time.

AN - 807613859; 2010-096391 AB - Fossil assemblages with high taxonomic richness also have high ecological richness (i.e., many modes of life). Bambach (1983) suggested that alpha diversity increased from the Paleozoic to the Cenozoic because new ecological modes of life were added to local ecosystems, and that diversification had depended on animals invading new, distinct niches. In one interpretation, this hypothesis implies "assembly rules" for local assemblages: once a particular ecological mode of life is occupied, competitors are excluded, and additional diversity requires using space or resources differently. However, analyses of level-bottom assemblages from the mid-Paleozoic and late Cenozoic reject structured assembly rules as the drivers of increased alpha diversity over time, implicating instead the general ecological effects of increased predation and disturbance. When organisms must balance a greater number of ecological needs, a greater number of ecological/morphological strategies become equally effective overall, as argued by Niklas and Marshall. In the Paleozoic, lower levels of predation and disturbance meant that feeding was the primary need, and only a few ecological strategies were optimal (two modes of life, both epifaunal and suspension feeding, accounted for over 80% of average local abundance in the data set). In the Cenozoic, animals must feed while avoiding intense predation pressure and frequent disturbance, and there are many ecological lifestyles that balance these demands. Therefore, no modes of life were superdominant; rather, a greater number were common or moderately common. Increased disturbance and predation may have facilitated the rise of initially less important modes of life by requiring animals to cope with several, rather than a few, equivalent needs, making a diversity of energetically more demanding ecological niches more viable. Local interactions such as predation and biological disturbance may be more important than competition in long-term alpha diversity trends, at least for the suspension feeders that dominate many marine fossil assemblages.

Drilling in 2007 was near Lindi, where previous TDP works had cored approximately 35 m of upper Campanian-lower Maastrichtian claystones and mapped upper Campanian to lower Oligocene sediments based on scarce surface exposures. During 2007, a total of 380 m of core was recovered. Three holes collectively spanned the uppermost Albian to upper Cenomanian (Planomalina buxtorfi sub-Zone to Rotalipora cushmani Zone) and include organic carbon isotopic evidence suggesting recovery of at least the base of OAE2; two holes recovered a thick sequence of the lower to middle Turonian (Whiteinella archaeocretacea to Helvetoglobotruncana helvetica Zones) with the Coniacian marker Dicarinella concavata in the highest samples; and one hole recovered the lower to upper Campanian (Globotruncanita elevata to Radotruncana calcarata Zones). Stratigraphic gaps exist in the lower Cenomanian, upper Turonian and Santonian, and the Cenomanian-Turonian boundary is not demonstrably conformable. Lithologies include thin intervals of light, coarse sandstones and sandy siltstones with occasional woody debris separating thicker intervals of dark claystone containing rare bivalves and ammonites and thin interbeds of silt to fine sandstone. Organic-rich, finely laminated claystones were also recovered at parts of the Turonian sequence. Beyond the refinements to knowledge of the local stratigraphy and subsurface geology, these results coupled with ongoing geochemical and biostratigraphic studies are being used to examine Late Cretaceous greenhouse climates. Of particular interest is the temperature history in the region, whether sedimentological and geochemical data together support Late Cretaceous glacial episodes, and how the tropical-subtropical East African Shelf environment behaved during OAE2 and other Late Cretaceous events.

On Earth, understanding the origin of a geologic material as the summed history of its constituent grains is a proven and powerful strategy to maximize the information that can be gleaned from limited samples. Multiple properties such as size, sorting, roundness, and texture may reveal clues to transport regime (e.g. fluvial, glacial, eolian), transport distance and diagenesis, eruptive patterns and processes, and differentiation of primary or recycled (by surface processes) grains. The ability to directly compare Martian and terrestrial microscale textures and fabric elements is the first step in revealing those similarities diagnostic of various origin, transport and weathering regimes. However, terrestrial image atlases provide images either at the outcrop scale, or as processed microsamples (e.g. thin sections). A library of terrestrial analog images at the handlens scale bridges this gap, providing a crucial resource for comparative studies. We used a professional single lens reflex (SLR) digital camera with interchangeable lens capability and megapixel imaging. For most images, a 100mm f/2.8 macro lens was threaded into the lens adaptor and a twin-tube ring light was mounted on the extended lens. A tripod with a three-way head provided stability during high-resolution imaging. Formations of interest were imaged for context at outcrop scale, then features of interest were imaged at approximately 10 mu m/pxl to mimic the resolution of current and future Martian microscopic imagers. When possible, samples were taken of imaged formations for further analysis in the laboratory. The handlens atlas currently contains nearly 1000 images, each accompanied by supporting documentation and description. The atlas is searchable by key textural terms or by type of formation.

To systematize investigation, we use a classification scheme including both individual ridge and ridge network types, as well as associations with impact craters and fan-shaped features. The morphology of the ridges, their location downslope from higher topography (e.g., crater rims and scarps), and their association with fan-shaped forms indicate that most sinuous ridges formed through overland aqueous flow. Analysis of observations by individual ridge type leads to interpretation of most of these sinuous ridges as inverted fluvial channels or floodplains and a few as eskers, with the origin of the remaining ridges under continuing investigation. About 15% of the sinuous ridges are associated with impact craters, but data analysis does not support a causal relationship between the craters and the sinuous ridges. Instead, analysis of one sinuous ridge network associated with a crater indicates that the water source for the network was atmospheric in origin, namely, rainfall runoff or snowmelt. The broad areal distribution of these approximately 150 ridges and their various network morphologies suggest that an atmospheric water source is applicable to the population of sinuous ridges as a whole. This concentration of sinuous ridges is the largest single population of such landforms on Mars and among the youngest. These ridges are situated at a paleoscarp between the Cerberus plains and the Aeolis highlands, suggesting that the precipitation that formed them was orographic in origin. The ages of the equatorial MFF units in which this population of sinuous ridges is found imply that this orographic rain and/or snow fell during some period from the late Hesperian through the middle Amazonian.

Detailed investigations of mineralogy are lacking. One well recognized example is the Brushy Fork "albitite" dike in Pendleton County, West Virginia. This dike is exposed in the Brushy Fork stream and is approximately 9 m wide with a N. 83 degrees E. trend. The country rock is the Devonian Brallier Formation consisting of siliciclastics, dipping steeply toward the southeast at approximately 50 degrees . The dike intruded a fracture cross-cutting strike at an angle of 52 degrees . Previous workers report an age of 42.8 + or - 0.5 Ma and describe the texture of the rock as aphanitic, resembling a very fine grained quartz sandstone. The mineralogy has been described as consisting of >95 percent of equigranular, euhedral crystals of albite with trace amounts of small, euhedral biotite crystals, and more rarely ilmenite grains. Powder X-ray diffraction (XRD) and forty-four electron microprobe analyses (EMPA) indicate that the feldspar present in the rock is anorthoclase, not albite. Hypersolvus crystallization to produce anorthoclase indicates either low pressure or very dry conditions. Composition of the feldspar varied from Ab 0.39 to Ab 0.88 (Avg. Ab0.71) and Or 0.04 to Or 0.54 (Avg. Or 0.24). The average calcium and barium content in the anorthoclase, expressed as CaO and BaO, is 1.09 wt % and 0.28 wt%, respectively. Average iron content expressed as FeO is 0.40 wt%, which is quite high compared to most feldspars. Fe-Ti oxides occur as do trace amounts of chalcopyrite and interstitial quartz. Anhedral to subhedral hedenbergite grains also occur and contain significant amounts of MnO (Avg. = 2.35 wt %) suggesting minor solid solution with johannsenite. This is the first detailed study of mineral chemistry of the rock and suggests a more complicated history than previously believed.

Discrete and continuous data from over 50 sources, including both terrestrial and marine records, are used to interpret climate change on a continental scale and to identify regions with coherent patterns of aridity and temperature. We infer regional differences in broad climatic histories based on many climate indicators: lake level histories, magnetic susceptibility, pollen, dust, speleothem growth, and dune migration. All of the records compiled in this study are radiometrically anchored in time. We divided the continent into four climatic regions (1) North Africa, (2) the Sahel, (3) the Afrotropics, and (4) South Africa. We interpret regional differences in climate to result from changing global atmospheric circulation patterns including the location of the ITCZ. Circum-African sea surface temperature data are consistent and warm during the tropical belt megadrought period from approximately 105-90ka. This suggests that changes in the delivery mechanism of moisture to specific regions are responsible for the extreme aridity, and not the amount of moisture available to the entire continent from the surrounding oceans. We explore the extent to which these environmental changes provided the context for behavioral innovations seen in Middle Stone Age archaeological sites, perhaps through demographic shifts among early populations of Homo sapiens that included local increases in relative population pressure. Several archaeological indicators suggest behavioral change as a possible response to increased risk due to local environmental degradation. These include novel hunting technology, a broadened resource base, and early suggestions of social networks, the timing and relative abundance of which is assessed through a composite database of radiometrically dated archaeological assemblages.

They supposedly reflected massive, irreversible biotic changes on land that were thought to have happened about half a geological period prior to the changes in marine faunas that mark the more traditional geological era boundaries. The terms were applied initially only to terrestrial rocks from the Euramerican portions of equatorial Pangea, especially parts of central Europe, where the boundary between the Paleophytic and Mesophytic, the "eras" of interest here, was placed at the top of the German Rotliegends. More recently, the terms have been coopted to describe vegetation types (not chronostratigraphic units), even to the point where specific Linnean ordinal or class level clades (evolutionary lineages) of plants have been attributed solely to one vegetation type or the other at a global level. Furthermore, the "Paleophytic-Mesophytic" transition has been recognized in the largely taxonomically distinct vegetation types of temperate as well as the equatorial paleolatitudes. The result of this conceptual coopting of terms that already were of questionable value, is a blurring of the concepts almost to the point of meaninglessness. A reading of the literature indicates confusion in terms of what represents the "Paleophytic" flora vs. the "Mesophytic" flora, the botanical basis for the floras and the taxonomic scale at which they can be recognized, the geographic pattern and temporal correlation of the supposed transition, and the evolutionary and ecological significance of the vegetational changes these terms supposedly capture. We propose that these terms be completely and utterly abandoned as confusing and, worse yet, misleading. Evidence suggests that Paleozoic vegetation tracked climate, which should not come as a surprise in light of what is known of plant dynamics in the Holocene and Recent. Furthermore, the evidence for a global "Paleophytic" vs. "Mesophytic" "vegetation" is simply unsubstantiated by the fossil record. Rather, there appears to have been a complex of global species pools reflecting climate at many spatio-temporal scales. The vegetational changes occurring in the late Paleozoic thus can be understood best when examined as spatial-temporal changes in biome-scale species pools responding to major global climate changes, locally and regionally manifested.

What lessons should be drawn from these data, however, has proven to be rather contentious. Although we as paleontologists have made great progress in documenting the geological record of phenotypic evolution with greater thoroughness and sophistication, these successes have been limited by the use of verbal models of how phenotypes change. Descriptive terms such as "gradual" have been understood differently by different authors, and this has led to completely incompatible summary statements about the fossil record of morphological evolution. Here I argue that the solution to this ambiguity lies in insisting that different evolutionary interpretations be represented as explicit, statistical models of evolution. With such an approach, the powerful machinery of likelihood-based inference can be help resolve long-standing paleontological questions. Here I first review this approach and some aspects of its implementation. Then, I show how this approach leads to new traction on important issues in evolutionary paleobiology, including: understanding modes of evolution and determining their relative importance, separating evolutionary mode from tempo, assessing the evidence for hypotheses of punctuated change, and detecting adaptive evolution in the fossil record.

Long told that paleontologists ought to be content with a subsidiary role as mere documenters of evolutionary change or as stratigraphical "handmaidens" to geology, over the past hundred years many palcontologists have actively resisted restrictive pigeonholing and attempted to establish paleontology as an autonomous discipline with status equal to its cousins biology and geology. This essay will survey some of the efforts at paleontological "activism" over the past century, focusing particularly on institutional placement, intellectual contributions, and the use of arguments about the adequacy of the fossil record to bolster claims for disciplinary status.

None is more difficult than explaining the Cambrian explosion, the dramatic differentiation of most metazoan animal phyla and classes about 545-530 million years ago. Molecular paleobiology, the experimental and theoretical integration of the geologic and the genetic historical records of life, holds promise to help elucidate the causality of the Cambrian explosion, especially as it relates to understanding how so many animal body plans appeared in such a relatively short period of time, and why these body plans were so stable over the subsequent 500 million years. Three discoveries made over the last few years suggest that the answers to these problems might be right around the corner. First, the notion that phenotypic plasticity was higher early, as compared to later, in a clade's history has finally been confirmed and quantified for trilobites. Second, it has been shown that a recently discovered group of genes, microRNAs, regulate the precision of genic output, turning what is a fairly sloppy process (the number of transcripts derived from any genetic locus) into a precise number of protein molecules. And third, microRNAs are continuously being added to metazoan genomes, with their first major influx occurring at the base of the protostomes and deuterostomes, the very animals that so dramatically make their first appearances in the Early Cambrian. I propose that because phenotypic variation decreases through geologic time, that because miRNAs decrease genic variation in output levels, and because the number of miRNAs found within a genome increases through geologic time, miRNAs might be instrumental in the canalization of development, sacrificing phenotypic variation for developmental precision, and ultimately allowing for increases to morphological complexity. Hence, part of the solution to the Cambrian conundrum might be microRNAs, how they control development through ontogenetic time, and how they evolve through geologic time.

When the Paleontological Society was founded no unambiguous fossils were known from the immense stretch of Precambrian time and no hominine fossils were known from Africa. Rigorous phylogenetic analysis and a seat for paleontology at the "high table" of evolutionary biology were in the future. Where once we learned a series of guide fossils and thought we had studied paleontology, now students explore taphonomy, paleoeocology, geobiology and macroevolution in our general courses on paleontology. This paper attempts to take notice of some of the highlights of our evolution from a field focused on cataloging and describing the contents of the fossil record into a complex, multidisciplinary endeavor focused on analytical study of general questions. Some of those hits have been discoveries that document the course of evolution, some have been new conceptual approaches that give us insights that link pattern to process, some are new ways of compiling, analyzing or communicating our knowledge. But with all that the study of the history of life remains at the heart of our profession. The change has been the shift in goal from description to understanding of that history, from "what" to "how." The greatest hits have been the steps that have opened the way to understanding, that have made following the path possible.

Ecological factors relate to the species' niche, its environmental or biotic limits in multidimensional space, while historical factors pertain to a species' ancestry, specifically the location at which a species evolved. Historical limitations are primary during speciation, while ecological factors control the subsequent expansion and contraction of species range. By assessing biogeographic changes during the lifespan of individual species, we can assess the relationship between paleobiogeography, paleoecology, and macroevolution. Quantitative paleobiogeographic analyses, especially those using GIS-based and phylogenetic methods, provide a framework to rigorously test hypotheses about the relationship between species ranges, biotic turnover, and paleoecology. These new tools provide a way to assess key questions about the co-evolution of life and earth. Changes in biogeographic patterns, reconstructed at the species level, can provide key information for interpreting macroevolutionary dynamics-particularly speciation mode (vicariance vs. dispersal) and speciation rate during key intervals of macroevolutionary change (biodiversity crises, widespread invasion events, and adaptive radiations). Furthermore, species ranges can be reconstructed using ecological niche modeling methods to examine the effects of environmental controls on geographic range shifts. Particularly fruitful areas of investigation in future paleobiogeographic analysis include (1) the relationship between species ranges and speciation events/ mode, (2) relationship between shifting ecological regimes and range expansion and contraction, (3) the impact of interbasinal species invasions on both community structure and macroevolutionary dynamics, (4) the mechanics of transitions between endemic to cosmopolitan faunas at local, regional, and global scales, (5) how-ecology and geographic range impacts species extinction during both background and crisis intervals. Three case studies are presented to illustrate both the methods and utility of this theoretical approach of using paleobiogeographic patterns to assess macroevolutionary dynamics. The first case study examines paleobiogeographic patterns in shallow marine invertebrates during the Late Devonian Biodiversity Crisis. During this interval, speciation by vicariance declined precipitously and only species exhibiting expanding geographic ranges survived the crisis interval. Patterns of biogeographic change during the Late Ordovician Richmondian invasion (Cincinnati Arch region) reveal similar patterns; speciation rate declines during invasion intervals and widely distributed endemic species are best able to survive in the new invasive regime. Phylogenetic biogeographic patterns during the Miocene radiation of North American horses suggest climatic parameters were important determinants of speciation and dispersal patterns.

The temporal ranges of gap-bound packages, compiled separately for different geographic locations, permit area-weighted, survivorship-based measures of rock quantity and spatio-temporal environmental continuity to be measured. Analytical basin fill models suggest that the parameters controlling sedimentation and sequence stratigraphic architecture, such as base level and sediment supply, can be detected quantitatively by macrostratigraphy. Macrostratigraphic analysis of the marine/sedimentary rock record in the United States at a temporal resolution of approximately 10 (super 6) years reproduces most of the well-known Sloss sequences, but it also identifies two prominent megasequences, the Paleozoic and Modern megasequences, which are separated by a Permian-Triassic discontinuity and Phanerozoic minimum in rock quantity. Many short- and long-term features of the macroevolutionary history of marine animals are reproduced by macrostratigraphy, including 1) many patterns in genus richness, 2) patterns in rates of genus extinction and, to a lesser degree, rates of origination, and 3) patterns of extinction selectivity and the shifting relative richness of Sepkoski's Paleozoic and Modern evolutionary faunas. The extent to which macrostratigraphy reproduces the macroevolutionary history of marine animals transcends what is expected by geologically-controlled sampling biases. Instead, the processes which control the spatio-temporal dynamics of shelf sedimentation, including expansions and contractions of shallow epicontinental seas, have probably exerted a consistent influence on the macroevolutionary history of marine animals. Exploring the common cause hypothesis by putting fossils back into rocks and rocks into a new quantitative framework for physical environmental change holds considerable promise for paleobiology.

In this paper, I compare the proposed mechanics of a heuristic developed to explain transformational change in systems ecology with various paleontological patterns and hypotheses for its conceptual homology and thus explanatory power in causal terms. The adaptive cycle heuristic, which has potential to influence current environmental and natural resources law and policy, has two components: 1) cycles that alternate between long periods of growth and shorter periods that create opportunities for innovation (new structures or conditions that become economically successful), and 2) the interaction of nested sets of such cycles (panarchies) across space and time scales. I critically evaluate three basic underlying tenets of the adaptive cycle related to the circumstances of innovation-empty niche space, competition and availability of resources-because of their importance to the development of a theoretical framework for understanding the ecological dimension of opportunity in biological evolution. I conclude that not all of the proposed mechanics and observed phenomenology of the adaptive cycle are appropriate in biological evolution. I draw insight, however, from the hierarchical nature of the heuristic to outline a "panarchical" conceptualization of the escalation hypothesis; I identify self-organization, emergence, selection and adaptation, and feedback as phenomena that are held in common across systems and scales, which influence how entities in the economic hierarchy of life arise, interact and evolve.

Here we illustrate our molecular approach to paleobiology with lipid biomarker data collected from rock bitumens and kerogens hosted within sedimentary units of the Neoproterozoic Huqf Supergroup, South Oman Salt Basin, Sultanate of Oman. We emphasize that parallel analyses of free and bound biomarker pools affords more confidence that we have correctly identified syngenetic compounds. One enigmatic class of compounds that is prominent in many late Proterozoic and Cambrian sedimentary rocks and oils, including from the Huqf Supergroup, is a series of C (sub 14) -C (sub 30) mid-chain methylalkanes which were originally denoted X-peaks. Despite their abundance in the Precambrian rock record, little is known about the organisms responsible for their biosynthesis. Here we propose a possible origin of X-peak methylalkanes from colorless sulfur bacteria (a very heterogeneous group of chemolithotrophic gamma -proteobacteria). In modern marine settings, these bacteria are abundant mat formers wherever a sedimentary sulfide-rich horizon intersects the seafloor producing a steep geochemical redox gradient. This condition may have been met more commonly on shallow marine shelves in late Neoproterozoic basins and these benthic mats may have acted as environmental buffers consuming hydrogen sulfide. If our hypothesis is correct, proliferation of sulfide-oxidizing benthic microbial mats, commencing in the late Cryogenian in South Oman Salt Basin, implies unique and specific benthic conditions during the evolution of the earliest metazoans.

Research in recent years has necessarily focused on determining the existence (or otherwise) of fossils in the Early Archaean rock record. Nonetheless, despite numerous reports of microfossils(?) and stromatolites, consensus on the existence of life in the Early Archaean has been elusive (e.g. Moorbath, 2005). However, new techniques and approaches are allowing more confident interpretation of the Archaean fossil record, and the nature of the earliest biosignatures can be used to inform our understanding of emergent ecosystems on Earth and perhaps on other terrestrial planets. Evidence is mounting that microbial ecosystems may have had a firm foothold as early as approximately 3.5 Ga (Tice and Lowe, 2004; Schopf, 2006; Hofmann et al., 1999; Allwood et al., 2006, 2007b; Westall et al., 2006; Westall and Southam, 2006). Significantly, there is now also evidence that the Early Archaean record may not be as meager and cryptic as previously thought. For example, the 3.43 Ga Strelley Pool Chert of the Pilbara Craton of Western Australia contains kilometer-scale tracts of a fossilized stromatolite (microbial?) reef (Allwood et al., 2006, 2007b) and provides a large suite of evidence that is consistent with life's existence. Moreover, the rapidity with which the Strelley Pool reef established itself on a newly-submerged landmass suggests that life was well established by that time, waiting in the wings in planktonic form until conditions favored sessile biofilm formation. The rich vault of information in such rocks as the Strelley Pool Chert may shed light not only upon life's antiquity, but also on the nature of early organisms and ecosystems, the environments that nurtured them, the processes that aided preservation of biosignatures and the palaeontological approaches needed to interpret them. This in turn will be a valuable guide in the search for-and interpretation of-ancient microbial biosignatures in the geologic record of other planets or moons.

Here, we outline recent methods for framing paleoecological questions that should facilitate the further quantitative evaluation of paleoecological hypotheses. First, we describe theoretical ecospaces, which are frameworks for classifying the ecologic properties of individuals or species based on multiple characters. We discuss the utility of theoretical ecospace in understanding evolutionary constraints and biodiversification, among other topics. Second, we discuss the reconstruction of high-resolution paleoecological gradients using ecological ordination techniques. Ordination can help uncover the paleoenvironmental factors that controlled fossil assemblage composition, track these factors through time, and evaluate the environmental and ecological context of major biotic changes. As an example, we present a new gradient analysis of the Yorktown Formation (Pliocene) of Virginia in which substrate and disturbance controlled molluscan assemblage composition. As a further example, we ordinate samples of mid-Paleozoic and late Cenozoic marine fossil assemblages based on their ecological content (as determined using a theoretical ecospace) to test whether the same environmental and ecological factors controlled the distribution of ecological lifestyles in both time intervals, despite the many differences between them. Although depth-related variation is evident in both data sets, the Cenozoic samples show stronger evidence of environmental control on ecologic content within depth zones. In contrast, Paleozoic gradients are consistent with a more random component in assemblage content. These analyses are quite preliminary, however, and should be verified with more extensive data.

A symbiosis between an infesting animal and a skeleton-producing host can form a bioclaustration cavity that directly preserves the association and has a high preservation potential. Identification of ancient mutuals and parasites must reject the null hypothesis of commensalism by demonstrating that the symbiosis correlates with a positive or negative change in host fitness as compared to a non-symbiotic relative of the host taxon. Reviews of the Paleozoic record of marine symbionts show that the majority are hosted by colonial animals, especially corals and calcareous sponges. These hosts include structural forms that have moderate to high levels of integration and can support bioclaustrations between clonal units, mitigating the negative effects of symbionts, and perhaps facilitating the symbiosis. The fossil record is biased toward recording long-lasting, widespread, equilibrated associations. By contrast, parasitisms that are especially negative to the host are expected to be fossilized rarely. The symbiotic associations that form bioclaustrations may also represent an endolithic adaptive strategy in response to biological antagonisms, such as predation and spatial competition. The Late Ordovician rise in symbiotic bioclaustrations joins burrows and borings as trace fossil examples of infaunalization strategies that accompany the Ordovician faunal radiation.

Although disciplinarily inclusive, our founders were an elitist, demographically limited group. Constitutional revisions over the past century trace the evolution of the PS, including increased democratization (with a setback during the McCarthy Era, but accelerating following the turmoil of society as a whole during the 1960s), internationalization, independence from the GSA and our sister organization SEPM, and broadening of our activities and concerns. Comments by Paleontological Society presidents, in their presidential addresses and/or a survey I conducted, reinforce these conclusions. In addition, the presidential addresses demonstrate the shifting concerns and interests of paleontologists over the past century: emphasis on stratigraphic paleontology during the early years of the Society; avoidance of the topic of evolution during the antievolution movement of the 1920s-1950s; lack of participation in the debates over continental drift; development of paleobiology. Many presidents focused on the identity of paleontology, either praising our potential for contributions to science and society or bemoaning our status and recommending remedies for our situation. Despite some predictions of impending extinction of paleontology and the PS, both our Society and our field remain vigorous as we begin our second century.

Leaves serve here as an example of how those advantages can be exploited. Over the history of vascular plants, three important transitions in leaf evolution-the origin of laminate leaves, the progressive loss of seed plant morphological diversity, and the evolution of more angiosperm-like leaves-also represent major shifts in leaf development and physiology. These transitions often occurred in parallel in different lineages, such as the evolution of marginal growth in each of at least four independent origins of laminate leaves during the Devonian and Carboniferous. Each also entailed dramatic reorganizations of leaf hydraulics. For example, the length of the finest distributary vein order varies from up to tens of centimeters down to hundreds of microns in successive groups of dominant seed plants. Angiosperms impose an additional trend upon these patterns with the evolution of their uniquely high vein densities. Vein density strongly influences and can provide a proxy for other physiological characteristics, such as assimilation and transpiration rates. The large increase in transpiration capacity accompanying the evolution of angiosperm leaf traits may even play an important role in feeding precipitation and thereby altering local climate.

Taxonomies are based strictly on evolutionary relationships with traits of organisms such as morphology and sequence data, being used as evidence for relationships. Two types of taxa are recognized--species that may be monophyletic or paraphyletic and clades that must be monophyletic. The phylogeny is an hypothesis of relationships that can be used to illuminate many areas of paleobiology including: unsampled morphology from incompletely preserved organisms, temporal distribution of taxa, and evolutionary patterns and mechanisms. Consequently, an understanding of phylogenetic assumptions, experimental design, and language are critical for the incorporation of phylogenetic taxonomies into larger studies of paleobiology.

Observed histories of organisms and Earth environments need to be linked under a set of uniformitarian assumptions to address this question. Functional morphology, which studies how organismal body parts interact with their physical environments, is an important tool in establishing the link. Being uniformitarian or ergodic, functional morphology is most robust when directly incorporating physical (or mechanical) principles into hypotheses and their tests. Such "physical functional morphology" may not be always possible, but the number of examples is slowly increasing. Once a series of robust functional inferences are made, it may be possible to study its correlation or correspondence with the historical record of environmental proxies. This framework was applied to the Mesozoic marine reptiles Ichthyopterygia, which is known for the evolution of fish-shaped body profiles in the derived clade Parvipelvia. A suite of evidence suggests that parvipelvians had advanced cruising ability and dark-adapted vision that were lacking in the more basal forms, which they replaced during the major marine transgression between the latest Anisian (Middle Triassic) and the middle Norian (Late Triassic). The ability to forage in broader expanses of and deeper water may have enabled parvipelvians to survive when shallow water environments became reduced during the major regression phase, but much more study is needed to test such an inference.

Major perturbations and innovations occurred in the Ediacaran climate, ocean, and biosphere systems. This paper reviews recent advances in Ediacaran glaciations, oxidation events, and biological evolution. There were one or more glaciations in the Ediacaran Period. Ediacaran successions also record multiple negative delta (super 13) C (sub carb) excursions in addition to the excursion associated with basal Ediacaran cap dolostones. These negative delta (super 13) C (sub carb) excursions possibly represent pulses of ocean oxidation events. The Ediacaran Period is also distinguished by two unique biotas-the Doushantuo-Pertatataka acritarchs and classical Ediacara biota-that characterize, respectively, the early and late part of the period. These two biotas appear to be separated by a glaciation and by a major negative delta (super 13) C (sub carb) excursion, although the exact temporal relationship among the climatic, geochemical, and biotic events is far from resolved. Future research should focus on improving geochronological, paleoenvironmental, and paleontological data from key Ediacaran successions in order to test the apparent and tantalizing couplings between evolutionary and environmental events.

This is facilitated when the fossil record is understood from a phylogenetic context. Phylogenetic analyses allow the identification of robust calibration points for molecular dating analyses, and in the absence of phylogeny, "conflicts" between fossils and molecules may arise that are based not on the data, but on methodology or taxonomic philosophy. More importantly, phylogenetic analyses using fossils can overturn evolutionary scenarios based solely on living taxa, and they can direct researchers in more appropriate directions. This is necessary if paleontology is to be fully integrated with both the Earth and life sciences.

Thus, poor taxonomic knowledge has tempered the tremendous potential of fossil leaves for constructing finely resolved records of biodiversity through time, extinction and recovery, past climate change and biotic response, paleoecology, and plant-animal associations. Moreover, paleoecological and paleo-climatic interpretations of fossil leaves are in great need of new approaches. Recent work is rapidly increasing the scientific value of fossil angiosperm leaves through advances in traditional paleobotanical reconstruction, phylogenetic understanding of both leaf architecture and the response of leaf shape to climate, quantitative plant ecology using measurable, correlatable leaf traits, and improved understanding of insect leaf-feeding damage. These emerging areas offer many novel opportunities to link paleoecology and neoecology. Increased collaboration across traditionally separate research areas is critical to continued success.

Here, I summarize the major themes that have emerged from the past thirty years of extinction research and highlight a number of promising directions for future research. These directions explore a central theme-the evolutionary consequences of extinction- and focus on three broad research areas: the effects of selectivity, the importance of recovery intervals, and the influence of spatial patterns. Examples of topics explored include the role that trait variation plays in survivorship, the comparative effects of extinctions of varying magnitudes on evolutionary patterns, the re-establishment of macroevolutionary patterns in the aftermath of extinction, and the extent to which spatial autocorrelation affects extinction patterns. These topics can be approached by viewing extinctions as repeated natural experiments in the history of life and developing hypotheses to explicitly test across multiple events. Exploring the effects of extinction also requires an interdisciplinary approach, applying evolutionary, ecological, geochronological, geochemical, tectonic, and paleoclimatic tools to both extinction and recovery intervals.

The resolution with which delta (super 13) C and delta (super 15) N values of soil organic matter (SOM) can be used to infer climate characteristics were examined from soils along two elevation transects in Ethiopia. Two transect characteristics permitted evaluation of temperature and precipitation effects separately and in tandem on delta values. First, transects differed from one another in precipitation but not in temperature. In addition, precipitation did not co-vary with elevation or temperature in the wetter transect. Vapour pressure deficits (physiologically meaningful measures of aridity affected by both temperature and precipitation) thus decreased more with elevation gain in the drier than in the wetter transect. In both transects, delta (super 13) C values of surface (<10 cm depth) SOM were highest at middle elevations and lowest at both the highest and lowest elevations. This humped relationship was preserved in presumably older SOM samples up to 300 cm depth. These trends support hypotheses about climate influences on delta (super 13) C values of SOM only from the middle to highest elevations. From the lower to middle elevations, the trends suggest the hypothesis that historical differences in land use pressures may have a greater and opposing influence than climate on delta (super 13) C values of SOM. The delta (super 15) N values were negatively related to elevation in the drier transect alone, supporting hypotheses that precipitation is the principal influence on delta (super 15) N values of SOM. Elemental analyses provide some affirmation for the hypothesis that the influence of precipitation on openness of local nitrogen cycling can cause delta (super 15) N values to increase with aridity. A problem in reconstruction of continental environments, per se, is to discern changes in climate from changes in land use. If differences in land use history have larger effects than climate on delta (super 13) C values of SOM then delta (super 15) N values of SOM may be valuable in conjunction with delta (super 13) C analyses for reconstructing aspects of land use and climate.

The results suggest that the high-density/low-diversity assemblage has appeared in the early 1900s, coinciding with the eutrophication of the bay resulting from the Japanese industrial revolution. This assemblage proliferated during the period 1960 to 1970 when the eutrophication and bottom-water hypoxia were most pronounced. The development of the assemblage has been characterized by an increase in the relative and absolute abundance of eutrophication-tolerant species (Ammonia beccarii, Eggerella advena, and Trochammina hadai) and a decrease in many other foraminiferal species, such as Ammonia tepida, Elphidium, Miliolinella subrotunda, and Valvulineria hamanakoensis, that are unable to tolerate low-oxygen conditions. Approximately thirty years after the imposition of discharge restrictions in the 1970s, this assemblage continues to predominate in the inner part of the bay, and E. advena is currently found across the entire bay. These records make a significant contribution to understanding the long-term relationship between anthropogenic impact and ecosystem change.

Two prefledging juveniles in the sample indicate breeding on the island. This shearwater was the general size of C. d. diomedea of the Mediterranean but differs in proportions and in qualitative characters and is described as Calonectris wingatei, new species. The species appears to have become extinct shortly after the time of deposition, when rising sea-level is also thought to have caused the extinction of the Short-tailed Albatross Phoebastria albatrus on Bermuda. The Neogene history of the taxa of Calonectris in the Atlantic basin is examined in the context of major geological and oceanographic events.

The Mn oxides birnessite [(Na,Ca,Mn (super 2+) )Mn (sub 7) O (sub 14) . 2.8H (sub 2) O)] and todorokite [(Ca,Na,K) (sub 0.3-0.5) (Mn (super 4+) ,Mn (super 3+) ,Mg) (sub 6) O (sub 12) . 3-4.5H (sub 2) O] have open structures that promote rapid cation exchange and sorption. Birnessite is a layered Mn oxide composed of edge-sharing MnO (sub 6) octahedra and todorokite is a tunnel structure composed of triple chains of edge-sharing octahedra. These minerals have been shown to be produced and dissolved by microorganisms in soils. Understanding the mechanisms by which Mn oxide structures change as a result of bacterial activity is necessary for models of the cycling of sorbed or exchanged elements. The most robust method for determining crystal structures is X-ray diffraction, which is lethal to living organisms in continuous time-resolved experiments. However, recent research has shown that isolated total membrane (TM) fractions from the facultative anaerobe Shewanella oneidensis can effectively reduce Mn oxides by direct contact. We have developed a method that allows continuous monitoring of crystal structure changes in Mn oxides as a result of the reductive dissolution by bacteria. We have documented significant structural transformations as well as the precipitation of two secondary phases, rhodochrosite (MnCO (sub 3) ) and hausmannite (Mn (super 3+) Mn (super 4+) (sub 2) O (sub 4) ). The biological reduction of birnessite is characterized by a significant contraction in the unit cell volume, due primarily to a decrease in the interlayer region. This change is likely the result of Mn(IV) reduction to Mn(III) in the octahedral sheets prior to dissolution. Our experiments also show that birnessite reduction can occur rapidly in the presence of high concentrations of TM and can be completely replaced by rhodochrosite and hausmannite in three days.

Studies of insect herbivory on fossil leaves provide important information on the association of plants and their insect herbivores that cannot be obtained separately from plant macrofossils or insect body fossils. In this study, we track changes in insect herbivory in a single basin during the late Paleocene and early Eocene (59-52.5 Ma). Four major temperature changes occurred during this interval: a gradual warming during the last two million years of the Paleocene; the abrupt and transient Paleocene-Eocene Thermal Maximum (PETM); an early Eocene cooling; and a warming to the sustained Cenozoic maximum approximately 53 Ma. Insect damage censuses were conducted at nine stratigraphic levels and 9071 fossil angiosperm leaves were examined for the presence/absence of 71 damage types (DTs). Damage frequency, number of DTs observed (standardized by the number of leaves in the analysis), and damage composition were analyzed on the bulk floras and individual host species. In general, the number of observed DTs increased as temperature increased through the late Paleocene, peaked in the PETM, decreased during the early Eocene cooling, and then increased again during the warming to the sustained Cenozoic maximum. The strong correlation between the number of DTs observed and mean annual temperature remains when the data are detrended using first differences. There is also a weak, marginally-significant correlation between temperature and damage frequency, and the abundance of highly specialized insect herbivore damage increases with warming. Temperature likely affects insect herbivory by allowing diverse insect populations from lower latitudes to migrate northwards and by influencing insect metabolism and population density. Thus, insect diversity, insect population density, and insect herbivory all increase as warming occurs.

This practice of subsuming a great deal of variation in a system of classification has the advantage of making book-keeping easier, but the disadvantage of depending heavily on how the classification is done. The introduction of the microcomputer has provided the opportunity for paleobotanists to keep track of vastly more information than was possible with non-electronic methods, making book-keeping easier than it has ever been in the past. One way to exploit this technological advance is the taxon-free approach. Instead of taking the species as a the basic unit, this essentially takes the character as the unit of recording, storage, and analysis. Instead of measuring species diversity, therefore (the number of species in a particular geographic area in a window of time), the taxon-free approach measures the number of observational units (usually specimens or species) sharing a character. Leaf architectural data provides an example of how this can supplement or replace the traditional taxonomic approach, especially when the questions being asked are fundamentally ecological rather than phylogenetic. Wider application of taxon-free methods along with the incorporation of morphological fields into current paleontological data-bases, and large-scale electronic data sharing will allow us more fully to apply the power that the computers have provided to questions of biological interest.

Understanding the thermal and exhumation history of these mountain ranges provides major insights to the particular tectonic configuration that trigger their evolution. The scarcely known Sierra Nevada de Santa Marta Massif show evidences of extensive Cretaceous to Eocene magmatism. Contact metamorphism and Al-in-hornblende geobarometry from arc granitoids (65-50 Ma), indicates pressures of 4-7 Kb, and 12-18 Km of unroofing since the Paleogene. Published K-Ar ages suggest cooling below 250 degrees C at about 48 m.y. Considering an arc geothermal gradient of approximately 50 degrees C, a minimum exhumation rate of 0.7 Km/Ma between 65-48 Ma can be determined. Zircon and apatite (U-Th)/He analyses from granitoids samples collected along a NW-SE profile yielded ages of 20-26 Ma and 8-15 Ma, respectively. These results suggest exhumation rates of 0.16 Km/Ma until the late Oligocene, that increased in the middle-late Miocene, where exhumation rates rise to 0.33 Km/Ma, similarly as including todays exposure level. Within a plate tectonic perspective, the Eocene exhumation is related to the post-collisional effects of the Caribbean accretion plus the magmatic underplating in a newly formed subduction zone. The relatively lower exhumation rates for the Oligocene and Miocene in comparison with the previous event, must be a consequence of the changes in the Caribbean-South American convergence towards a more transtensional relation, that shut down arc magmatism. The increase in the exhumation rate from the Miocene to Recent represents additional changes in the plate convergence relations that end-up with the subduction of the buoyant Caribbean Plate under South America, responsible for ongoing uplift and lack of isostatic equilibrium. The Caribbean exhumation rates also suggest that Santa Marta was isolated from the Andean geodynamics since the Eocene.

These works afford an outstanding opportunity to collect fresh samples along the working areas and study the geology of the isthmus from a set of brand new outcrops. Additional to the surface outcrops, hundreds of geotechnical cored-boreholes, both existing and from future drilling, will be re-examined and re-interpreted. An integrated approach combining detailed structural mapping, geochronology, geochemistry, palynology and paleomagnetism is being implemented to better understand the geology of the isthmus. The Project's main goals include the generation of a structural transect across the isthmus, the discrimination of the tectonic setting of major volcanic events, dating of these events, as well as establishing a palynological framework of the sedimentary units and systematic macro-fossil collection along the transect. Paleomagnetic data collected throughout the isthmus (Darien, Canal Zone and Azuero) will help understand the deformation mechanisms involved in the formation of the presently curved land bridge between the Americas so that several competing hypothesis can be tested (oroclinal bending, northwest-trending left-lateral shear, or a volcanic arc progressively accreted to the South American margin). Preliminary data collected along these profiles show clear cross-cutting relationships between volcanic assemblages (Bas Obispo, Panama, Caimito, Caraba, Las Cascadas, Pedro Miguel Formations), and the sedimentary sequences of the Culebra and Cucaracha Formations. These units contain the record of the growth of the Central American Arc over the Caribbean Large Igneous Province (CLIP) since the Late Cretaceous (90 Ma), and the interactions with the Pacific Plates and the South American margin.

They are also industrially important as catalysts, pigments, food additives, and dielectrics. Recent research has indicated an apparent reversal of thermodynamic stability between TiO2 phases at the nanoscale thought to be caused by an increased contribution of surface energy to the total free energy. Time-resolved X-ray diffraction experiments in which titanium oxides crystallize from aqueous TiCl4 solutions confirm that anatase, a metastable phase, is always the first phase to nucleate. Rutile peaks are observed only minutes after the first appearance of anatase, after which anatase abundance slowly decreases while rutile continues to form. Whole pattern refinement of diffraction data reveals that lattice constants of both phases increase throughout the crystallization process. Density functional theory (DFT) calculations were employed to model the energetics of nano-sized anatase and rutile using our refined structures. The calculated change in free energy between the incipient, surface-strained nanoparticles and the final microcrystals was only approximately 0.5 kJ/mol for each phase, far less than the 6 kJ/mol difference in free energy of formation between the two minerals needed to account for stability reversal. Surface energy calculations of model 1 and 2 nm nanoparticles did yield lower surface energies for anatase than for rutile by approximately 16 kJ/mol for both particle sizes, but these whole-particle surface energies were much higher than the sum of energies of each particle's constituent crystallographic surfaces. We attribute the excess energy to defects associated with the edges and corners of nanoparticles which are not present on a 2-D periodic surface. This previously unreported edge and corner energy may play a dominant role in the stability reversal of nanocrystalline titanium oxides, as well as other mineral systems susceptible to reversals in phase stability at the nano-scale.

Sediment cores were collected from seven stations in the Chesapeake Bay and mid-Atlantic continental shelf and slope during the spring, summer and fall of 2005 and 2006, and analyzed for Hg, MeHg, and ancillary parameters in sediment and porewater. In addition, mercury methylation, sulfate reduction and carbon dioxide and methane production rates were determined. Organic matter strongly controls inorganic Hg concentration and partitioning between the solid-phase and porewater, with the sandy sediment of the lower bay and shelf having lower Hg solid-phase concentrations and partition coefficients and relatively similar Hg porewater concentrations. MeHg concentrations and production rates in estuarine, shelf and slope sediments were comparable with those found in many freshwater systems, and controlled by similar mechanisms. Results suggest organic matter quantity and quality, sulfide and bioturbation strongly affect MeHg production in these sediments. Zones of relatively low dissolved sulfide concentration, but high microbial sulfate reduction rates, supported high rates of net MeHg production. These zones were most common in spring, and in sandy sediments of the lower bay and shelf and heavily bioturbated sediments of the slope. Preliminary diffusive flux calculations based on porewater data provide evidence that estuarine, shelf and slope sediments are all potential sources of MeHg to coastal waters, and reinforce the idea that offshore coastal sediments may be important sources of MeHg to coastal and open-water food webs.

Surface mining of coal occurred in the Spring Branch watershed from 1985 to 1997. Mine drainage was treated in a pond that discharged to Spring Branch from an adjacent 564 acre mine. Manganese oxide crusts developed in the stream channel below the pond outfall. In order to better understand how these and other banded manganese oxide crusts form and interact with aqueous environments, the mineralogy and chemistry of these stream deposits were investigated using reflected light microscopy, powder X-ray diffraction, and scanning electron microscopy. A series of light and dark bands is repeated 5-6 times within the manganese oxide crusts. Light-colored bands contain coarse-grained radial calcite crystals, and grade into a darker, rust-colored mix of calcite, clay minerals, and manganese oxide. Thin (>100 micrometers) distinct dark bands consist of a calcium-rich buserite phase. Imprints of elongate diatom frustules approximately 10 to 15 micrometers long and 2 to 3 micrometers wide are visible only in these thin manganese oxide-rich layers. Water samples were obtained from pond effluent and at a location downstream of the manganese oxide crusts. The pH of the pond effluent was near neutral (7.7), and the pH of the stream water remained constant from the pond to the mouth of the stream. These data suggest that precipitation of manganese oxides was not due to changes in pH. However, the dissolved manganese concentration in the stream water increased downstream from 560 to 3170 micrograms/liter suggesting that the stream water is a mix of mine drainage water with a lower manganese concentration and groundwater with higher manganese. Alternating calcite-rich and manganese-oxide/diatom-rich layers within the crust may be produced by annual or seasonal cycles in water temperature, rainfall, oxidation state, or microbial activity.

Provenance models depend on large databases; one obstacle has been finding a technique that provides a rich chemical signature of the gem while imposing negligible damage. This study uses LIBS analysis of ca. 100 beryl (Be (sub 3) Al (sub 2) Si (sub 6) O (sub 18) ) samples to develop a geochemical model for beryl provenance. In LIBS analysis, a pulsed Nd-YAG laser, operating at wavelength of 1064 nm and 91 mJ, is focused on the gem surface, causing ablation and excitation of atoms in a short-lived plasma. During cooling, atoms emit photons as electrons decay to lower-energy orbitals. This light is collected with an optic fiber, diffracted by seven Echelle gratings in Czerny-Turny configurations, and recorded on CCD cameras. The spectra, which contain intensities of most elements, are analyzed by Principal Components Analysis (PCA) using the program The Unscrambler. PCA reduces the complex signal to a few chemical variables (principal components), each of which has contributions from many of the wavelengths in the spectrum. Three PCA models were tested. Using the entire broadband spectrum, all beryls grouped together; only a few regions could be cataloged by provenance. The second method used was a PCA analysis of only the most significant elements in the first model: Li, Be, Ca, and Na. The resulting model was very similar to the broadband model. The third PCA model eliminated all Li, Be, Ca, and Na peaks and only used the peaks of lower intensity. The results were a little different and displayed some provenance groupings, but not in a definitive way. This study suggests that LIBS could be used to determine gem provenance if a sufficiently large data base were available.

However, analysis of Li is necessary, due to its petrological importance. Laser-induced breakdown spectroscopy (LIBS) is very sensitive to Li concentrations, and could possibly be a tool for Li analysis. The laser in LIBS ablates the surface of the specimen, generating a short-lived plasma, which puts the atoms and ions into an excited state. Photons are emitted when electrons return to a lower energy level, which are captured by a spectrometer, and finally displayed on a computer. In this study, standards for the Li calibration consist of synthetic glasses prepared from lithium tetraborate, sodium tetraborate, and pure SiO (sub 2) powders that were placed in graphite crucibles in a furnace at 1100 degrees C for 30 min. The standards were analyzed at a laser power of 91.5 mJ, and at a Q-Switch delay of -1.5mu m using an Ocean Optics LIBS 2500 system. Spectra were analyzed using multivariate analysis and the program Unscrambler. Multivariate analysis uses the entire spectrum to calibrate to each element, overcoming matrix effects that complicate single-element calibrations. The multivariate analysis resulted in a excellent calibration of known value vs. predicted value (r (super 2) =0.99988). To test this, a set of standard spectra not used in the calibration were analyzed; a plot of known vs. measured values yielded r (super 2) =0.927. Two lepidolites and two spodumenes of unknown Li concentrations were analyzed with the calibration, resulting in reasonable Li concentrations of 4.76 and 2.70 wt % Li (spodumene) and 3.68 and 4.33 wt % Li (lepidolite). These results suggest that LIBS can be developed to routinely analyze Li in rock and mineral samples using simple synthetic standards.

In this study, we have combined time-resolved X-ray diffraction with Cu isotope measurements to monitor changes to Cu-S mineral structures and isotopic fractionation upon Cu release. Pure, naturally occurring chalcocite (Cu (sub 2) S) powders were placed in flow-through capillary reaction cells and exposed to various concentrations of aqueous ferric sulfate for up to 4 hrs. Real-time diffraction data were collected at intervals of 2 min at beam line X7B, National Synchrotron Light Source. The (super R) Cu values of the leached Cu as well as the starting and final powders were measured using multi-collector inductively coupled plasma mass spectrometry. The powder diffraction data showed that the Cu bonding environment changed as Cu was leached from chalcocite, eventually forming covellite. The rate at which the transformation occurred depended on ferric sulfate concentrations. The delta (super 65) Cu values of the initial leachates sampled in all experiments ranged between 2.46 + or - 0.12ppm and 3.86 + or - 0.12ppm. These values decreased during the reaction. Fractionation factors were calculated by finding the difference between delta (super 65) Cu values of the aqueous Cu in the leachate and the isotopic value of the Cu in the residual mineral. The fractionation factors (Delta (sub aqueous-mineral) ) varied from 3.31 + or - 0.28ppm to -2.68 + or - 0.28ppm depending on reactant strength. The decreasing delta (super 65) Cu values of both leachate and minerals are not consistent with Rayleigh-type distillation models. This may suggest that more than one mechanism is influencing Cu isotopic fractionation factors throughout the reaction. A combination of effects, such as reaction rate and extent of reaction, influence the isotopic composition of the leachate and mineral residue during the dissolution of chalcocite.

Inflated sheets are known to have occurred within the distal margins of large shield volcanoes, flood-lava deposits, and submarine lava flows. Inflation features (inflation pits, tumuli, and inflated flow margins) have been observed within the Carrizozo and McCartys flow fields, suggesting that sheet inflation is also an emplacement style associated with monogenetic vents. In agreement with past works, we observed and reported on the same types of inflation features on both flows. Here, we present our field observations of flow textures associated with these two vents and compare them with published observations of inflated sheet flow textures. The McCartys and Carrizozo flow fields represent monogenetic, basaltic eruptions of lavas over < 1 degree slopes, at approximately 3000 and 5000 years ago respectively along the Rio Grande Rift System in New Mexico. We observed the following surface textures that together are suggestive of inflation, including: 1) grooved/lineated, meters-wide hummocks/swales, 2) smooth pahoehoe toes and ropes, 3) concentrated areas of broken slabs of smooth crust (sometimes reverse imbricated), 4) lava coils, 5) lava balls, 6) squeeze-ups, and 7) flow scars that form "wakes" associated with obstacles. In cross section the surface textures only occur within a thin upper layer over a continuous massive interior. Surface textures can abruptly change from smooth to broken and rough with no disruption of the interior beneath the surface transition. The surface layer is typically segregated from the massive interior by a vesicle rich zone. We conclude that inflated lava sheets are an emplacement-related morphology that is pervasive throughout basaltic terrains, and is indicative of a constant local lava supply over low slopes, regardless of the volcano-tectonic setting or vent conditions.

There are many proposed causes of trends in body size such as Cope's Rule, but there are increasing indications that, at least among microfossils, persistent body size trends can be related to long-term secular changes in environmental and climatic conditions. Here we present an analysis of body size evolution for the entire ostracode fauna from a site in the deep Indian Ocean (DSDP 253, 1962m water depth). For the interval spanning the last 40 million years, we tracked body size (measured as the projected area of valves) within specified instars in over 20 species-level evolutionary lineages and compared it to deep-sea temperature changes as recorded by published oxygen isotope and Mg/Ca proxies. For evolutionary transitions across all lineages considered jointly, we fit using maximum-likelihood four different evolutionary models: (i) an unbiased random walk, (ii) directional evolution (as in Cope's Rule), (iii) evolutionary stasis, and (iv) a optimum-tracking model in which body size evolution follows changes in deep-sea temperature. Results obtained thus far reveal that many but not all lineages show net increases in body size over time. In addition, there is a significant negative correlation between temperature and body size changes: these ostracode lineages have generally become larger-bodied with cooling of the deep ocean waters. Of the four evolutionary models considered, temperature tracking is the most highly supported. These results support views suggesting that long-term body size trends arise not from generic advantages of larger bodies, but instead from long-term directional changes in environmental circumstances.

We present a synthesis of patterns and possible causes of species diversity variation in benthic deep-sea ostracodes at several Deep-Sea Drilling Program (DSDP 607, 610) and Ocean Drilling Program (ODP 925, 982, 1055) sites in the North Atlantic Ocean, which together cover the last 3 million years of climatic evolution from relatively stable warmth to high-amplitude glacial-interglacial cycles. Faunas from mid-latitude cores on the Mid-Atlantic Ridge show a positive correlation between warm temperatures and high species diversity. In the subpolar regions of the Rockall and Iceland Plateaus, this pattern is reversed for the last 200 thousand years when the highest diversity occurs during major glacials represented by Marine Isotope Stages (MIS) 2-4 and 6. Spikes in subpolar benthic diversity during glacial periods may be caused by ice rafting during Heinrich events, which would have less influence in the lower-latitude North Atlantic. Heinrich events reduce North Atlantic surface temperatures and salinity every approximately 6-12 ka, dramatically decreasing surface productivity. Higher diversity during Heinrich events may be explained either by surface productivity changes or benthic habitat disturbance by ice-rafted debris.

Previous work demonstrated that the Cambrian explosion of marine life was characterized by stratigraphic range extensions (intervals of complete non-preservation) of <10 (super 7) years, thereby validating the rapidity of that unique episode in Earth history (Rivera 2007). The present analysis examines the origination of twenty higher taxa throughout Paleozoic time. At the 50% confidence level, sampled taxa had estimated range extensions from 3.3 X 10 (super 5) to 1.3 X 10 (super 7) years. However, only three taxa (15%) extend into earlier geologic ages or epochs. Polychaeta (Middle Cambrian) extends into the Early Cambrian, while Chondrichthyes and Osteichthyes (both Late Silurian) extend into the Early and Middle Silurian, respectively. At the 80% confidence level, sampled taxa had estimated range extensions from 7.7 X 10 (super 5) to 3.1 X 10 (super 7) years. Eight taxa (40%) extend into earlier geologic ages or epochs. Subphyla or classes appearing in the Early Cambrian Atdabanian Age (Malacostraca, Ostracoda, Bivalvia, and the extinct Blastozoa) are estimated to extend into the earlier Tommotian Age. Polychaeta may extend even deeper into the middle of the Early Cambrian Manykaian Age (535 Ma), while Asterozoa extends deeper into the Early Ordovician. Finally, Chondrichthyes and Osteichthyes extend into the Late Ordovician and Middle Silurian, respectively. At either confidence level, the following general patterns emerge: 1) Coleoidea still originates in the Early Devonian; 2) the Ordovician origination of Crinoidea, Bryozoa, Echinoidea, and the extinct Ammonoidea is confirmed, as is the Late Cambrian origin of Gastropoda, Cephalopoda, and Nautiloidea; 3) the extinct classes Graptolithina and Conodonta, despite some range extension, still originate in the Middle Cambrian; and 4) Brachiopoda and the extinct class Trilobita still originate in the Early Cambrian.

The presence of clay minerals and variations in stratal geometries and textures of beds, for example, make it possible to define several depositional environments within Holden and Eberswalde Craters. The mineralogy and stratigraphy/morphology of deposits in these craters are consistent with alluvial, fluvial, and lacustrine processes. These craters are themselves part of the larger Uzboi-Ladon-Margaritifer (ULM) system, which spans thousands of kilometers from the southern highlands to the northern lowlands. Large, highly eroded craters within this system act as sedimentary sinks, and combining mineralogy from spectroscopy with morphology shows that in some cases the local sediment source area(s) can be defined. Clays in the Noachian units in the ULM system consist almost entirely of Fe/Mg smectites, suggesting water-to-rock ratios were too low or aqueous conditions too short lived for significant dissolution and formation of secondary Al-bearing phases (e.g., feldspar to kaolinite). This is in contrast to the regional morphology, which suggests that the ULM system records a long history of deposition, erosion, and aqueous processes. Surrounding crater walls and rims contain clays and exhibit fluvial erosion patterns, suggesting they are local source areas. However, the spectral strength of clay features in potential source regions are commonly weaker than clay signatures in the deposits to which they contribute. This may be caused by a preferential accumulation of fine-grained clay-rich material in rock types associated with certain depositional settings (e.g., mudstones/shales) or by in situ formation of clays in standing bodies of water. Sedimentary deposits such as these, which can potentially be linked to their source region, are excellent targets for future exploration and sample return.

Where do these unique taxa fit into the tree of life? Their phylogenetic placement has been complicated by the fact that the organisms may have some, but not all, morphologic characters that are used to identify modern phyla. By understanding if these organisms are stem-groups, crown-groups, or new phyla entirely, we cast new light on the nature of the Cambrian Explosion. In order to understand how Burgess Shale taxa relate to modern crown-group taxa, an extensive morphologic range for modern taxa is required. Both modern and Burgess Shale ecdysozoans (chosen for their abundance) were coded with a list of morphologic characters and plotted in morphospace. The range of modern taxa's morphology will be used as the proxy for phyla. The Burgess Shale taxa were assigned as stem-group (ancestral), crown-group (within the phylogenetic group), or in new phyla based on the amount of disparity between the Burgess taxa and the ranges of modern taxa. Burgess organisms were placed within these groups based upon the distance between it and the centroid of the range of modern taxa within a phylum. If the distance is comparable to the average distance within the range, the taxa was considered within the crown group. If the distance was somewhat larger, it was a stem group, and much larger indicated a new phylum. Using this method, the number of phyla during the Cambrian can be estimated and conclusions can be drawn about the amount of overall disparity during the Cambrian Explosion.

At 23 Ma, the Cocos and Nazca Plates split from the Farallon with the formation of spreading ridge CNS-1. This plate reconfiguration, along with the subsequent formation of ridges CNS-2 (19.5Ma) and CNS-3 (14.7Ma) caused incremental counter-clockwise northward rotation of the Cocos Plate motion vector, and led subduction to become near margin perpendicular. During this time interval standard arc magmatism in Panama was dominant and was similar to Miocene magmatism in Nicaragua. At 9.5 Ma the Panama Fracture Zone became active and NE corner of the Cocos Plate was captured by the Nazca plate. This event is associated with nearly equal 90 degrees rotation of the outboard plate motion vector offshore of Panama. Outboard plate motion changed from near perpendicular to near margin parallel. At the same time the arc experienced greatly increased silicic magmatic activity. The nearly equal 10 Ma silicic volcanic event is observed at multiple volcanoes including El Valle, La Yeguada and possibly in the Talamanca Range of southern Costa Rica. This event is characterized by SiO (sub 2) values up to 75%, K (sub 2) 0 > 3%, Mg#(mol) < 30, increased Ba/La ( nearly equal 80), Sr/Y ( nearly equal 50) and La/Yb ( nearly equal 10) ratios. The rocks are also peraluminous with A/CNK ratios of 1.0-1.44, which is suggestive of crustal assimilation. The 10 Ma event exhibits similarities with younger (<3Ma) adakitic rocks that occur after Cocos Ridge began to subduct, but lack the extreme Sr/Y and La/Yb ratios and therefore must have formed by a different process. One potential explanation of the 10 Ma tectonic and magmatic events is that they mark the initiation of the collision between South America and Panama.

He alleged that the Barringer family, who held title to the crater, was depriving American citizens of its scenic beauty and scientific value. He then reportedly went on to make the unauthorized--and false--claim that the family would be receptive to a fair purchase offer for the crater. The Barringers, who had not been given advance warning of the petition and were not present at the meeting, felt ambushed. They quickly and forcefully rebutted Nininger's allegations, made it clear they had no intention of relinquishing their title to the crater, and terminated his exploration rights. What led Nininger to such a curious and self-defeating act? Based on our reading of his voluminous personal correspondence, we conclude that it was rooted primarily in his complex relationship with Frederick Leonard and Lincoln LaPaz, and his desire to establish a national institute for meteoritical research--with them, originally, but after a serious falling out, on his own. Prevented from moving his American Meteorite Museum to the crater rim, Nininger wondered what would happen if the crater was nationalized and made into a public park, with an accompanying tourist center and museum. With characteristic elan, he could picture himself at its head, with a secure salary and adequate space to exhibit his meteorite collection.

We present a simple model of cladogenetic diffusion over evolutionary time that omits explicit mechanisms for inter-specific competition and other microevolutionary processes yet fully explains the shape of this distribution. We estimate the model's parameters from fossil data on terrestrial mammals since the K/T boundary and find that it robustly reproduces the distribution of 4002 mammal species from the late Quarternary. The observed fit suggests that the asymmetric distribution arises from a fundamental tradeoff between the short-term selective advantages (Cope's rule) and long-term selective risks of increased species body size, in the presence of a taxon-specific lower limit on body size.

Reasons for this include both differences in the difficulty in recognizing distinct homologies and differences in underlying evolutionary processes. We investigate this common wisdom using simulations modeled on empirical data sets. We use compatibility to describe the structure of over 200 published matrices. (Compatible character pairs are those that do no necessarily imply homoplasy; for two matrices with the same number of taxa and characters, compatibility decreases as rates of change and homoplasy increase.) We then simulate phylogenies and matrices to match the number of taxa, characters and states per character states until we achieve match the empirical compatibility. Because most published phylogenetic inferences use minimum-steps parsimony (MP), we then find the MP tree(s) for each simulated matrix and contrast it with the correct phylogeny. MP trees are most accurate when compatibility is high relative to the number of sampled taxa, which in turn tends to be highest among vertebrates, followed by echinoderms; trilobites and mollusks typically rank lower, with brachiopods ranking lowest. Correspondingly, simulations show that vertebrate-based matrices yield the MP trees for which over 90% of the inferred clades match real clades, and for which nearly 20% of matrices have MP trees matching the true tree. Echinoderm-based matrices yield MP trees in which nearly 90% of clades match real clades; this drops to approximately 80% for both trilobite- and mollusk-based matrices, and 75% for brachiopod-based matrices. Within vertebrates, dinosaur-based matrices yield the most accurate MP trees, followed closely by mammals; fish-based matrices yield the least accurate MP trees. Notably, mammal-based data sets based largely on teeth yield worse MP trees than those based on skeletal characters. These results are consistent both with familiarity breeding accuracy and more challenging underlying evolutionary models for particular groups and character systems.

New localities from the Kapedo Tuffs augment the sparse sample of MSA sites from the northern Kenya Rift. Tephrostratigraphic correlation with dated pyroclastic deposits from the adjacent volcano Silali suggests an age range of 135-123ka for archaeological sites of the Kapedo Tuffs. Comparisons of the Kapedo Tuffs archaeological assemblages with those from the adjacent Turkana and Baringo basins show broad lithic technological similarity but reveal that stone raw material availability is a key factor in explaining typologically defined archaeological variability within this region. Spatially and temporally resolved comparisons such as this provide the best means to link the biological and behavioral variation manifest in the record of early Homo sapiens.

In addition to ancient DNA analyses involving a single or few individuals, population level studies are now possible. Biases inherent in estimating population parameters and history from modern genetic diversity are exaggerated when populations are small or have been heavily impacted by recent events, as is common for many endangered species. Going directly back in time to study past populations removes many of the assumptions that undermine conclusions based only on recent populations. Accurate characterization of historic population size, levels of gene flow and relationships with other populations are fundamental to developing appropriate conservation and management plans. The incorporation of ancient DNA into conservation genetics holds a lot of potential, if it is employed responsibly.

We evaluated longer-term changes in the abundance of larger (>1 kg) mammals in fragmented and intact rainforest and in riparian 'corridors' in tropical Queensland, with data from 190 spotlighting surveys conducted in 1986-1987 and 2006-2007. In 1986-1987 when most fragments were already 20-50 years old, mammal assemblages differed markedly between fragmented and intact forest. Most vulnerable were lemuroid ringtail possums (Hemibelideus lemuroides), followed by Lumholtz's tree-kangaroos (Dendrolagus lumholtzi) and Herbert River ringtail possums (Pseudocheirus herbertensis). Further changes were evident 20 years later. Mammal species richness fell significantly in fragments, and the abundances of 4 species, coppery brushtail possums (Trichosurus vulpecula johnstoni), green ringtail possums (Pseudochirops archeri), red-legged pademelons (Thylogale stigmatica), and tree-kangaroos, declined significantly. The most surprising finding was that the lemuroid ringtail, a strict rainforest specialist, apparently recolonized one fragment, despite a 99.98% decrease in abundance in fragments and corridors. A combination of factors, including long-term fragmentation effects, shifts in the surrounding matrix vegetation, and recurring cyclone disturbances, appear to underlie these dynamic changes in mammal assemblages. Dinamica a Largo Plazo de un Ensamble de Mamiferos de un Bosque Lluvioso FragmentadoResumen:La fragmentacion del habitat es una severa amenaza para las biotas tropicales, pero se conoce poco sobre sus efectos a largo plazo. Evaluamos cambios de largo plazo en la abundancia de mamiferos mayores (>1 kg) en bosque lluvioso fragmentado e intacto y en 'corredores' riberenos en Queensland, con datos de 190 muestreos con reflector llevados a cabo en 1986-1987 y 2006-2007. En 1986-1987, cuando la mayoria de los fragmentos ya tenian entre 20 y 50 anos, los ensambles de mamiferos difirieron significativamente entre bosque intacto y fragmentado. Los mas vulnerables fueron zarigueeyas (Hemibelideus lemuroides), seguidas por canguros arboricolas (Dendrolagus lumholtzi) y zarigueeyas (Pseudocheirus herbertensis). Mayores cambios fueron evidentes 20 anos despues. La riqueza de mamiferos decayo significativamente en los fragmentos, las abundancias de 4 especies, Trichosurus vulpecula johnstoni, Pseudochirops archeri, Thylogale stigmatica y D. lumholtzi, disminuyo significativamente. El hallazgo mas sorprendente fue que H. lemuroids, un especialista de bosque estricto, aparentemente recolonizo un fragmento, no obstante un 99.98% de disminucion en abundancia en los fragmentos y corredores. Una combinacion de factores, incluyendo los efectos de la fragmentacion a largo plazo, cambios en la matriz de vegetacion circundante y las perturbaciones ciclonicas recurrentes, parece subyacer en estos cambios dinamicos en los ensambles de mamiferos.

Nevertheless, questions remain regarding relative sensitivity of different taxa, habitat specialists, and functional groups, and whether implications for biodiversity conservation vary across regions. We quantitatively reviewed data from ant, bird, and tree biodiversity studies in coffee agroecosystems to address the following questions: Does species richness decline with intensification or with individual vegetation characteristics? Are there significant losses of species richness in coffee-management systems compared with forests? Is species loss greater for forest species or for particular functional groups? and Are ants or birds more strongly affected by intensification? Across studies, ant and bird richness declined with management intensification and with changes in vegetation. Species richness of all ants and birds and of forest ant and bird species was lower in most coffee agroecosystems than in forests, but rustic coffee (grown under native forest canopies) had equal or greater ant and bird richness than nearby forests. Sun coffee (grown without canopy trees) sustained the highest species losses, and species loss of forest ant, bird, and tree species increased with management intensity. Losses of ant and bird species were similar, although losses of forest ants were more drastic in rustic coffee. Richness of migratory birds and of birds that forage across vegetation strata was less affected by intensification than richness of resident, canopy, and understory bird species. Rustic farms protected more species than other coffee systems, and loss of species depended greatly on habitat specialization and functional traits. We recommend that forest be protected, rustic coffee be promoted, and intensive coffee farms be restored by augmenting native tree density and richness and allowing growth of epiphytes. We also recommend that future research focus on potential trade-offs between biodiversity conservation and farmer livelihoods stemming from coffee production. Perdida de Biodiversidad en Paisajes Cafetaleros en Latinoamerica: Revision de la Evidencia en Hormigas, Aves y ArbolesResumen:Diversos estudios han documentado las perdidas de biodiversidad debido a la intensificacion del manejo de cafe (disminucion de la riqueza y complejidad del dosel). Sin embargo, persisten preguntas sobre la sensibilidad relativa de diferentes taxa, especialistas de habitat y grupos funcionales, y si las implicaciones para la conservacion de la biodiversidad varian entre regiones. Revisamos cuantitativamente los datos de estudios de biodiversidad de hormigas, aves y arboles en agroecosistemas de cafe para abordar las siguientes preguntas: [iquest]La riqueza de especies declina con la intensificacion o con las caracteristicas individuales de la vegetacion? [iquest]Hay perdidas significativas de riqueza de especies en los sistemas cafetaleros en comparacion con los bosques? [iquest]Es mayor la perdida en especies de bosque o en grupos funcionales particulares? y [iquest]Las aves o las hormigas son mas afectadas por la intensificacion? En los estudios revisados, la riqueza de hormigas y aves declino con la intensificacion del manejo y con los cambios de vegetacion. La riqueza de especies de todas las hormigas y aves y la de especies de hormigas y aves de bosque fue menor en la mayoria de los agroecosistemas cafetaleros que en los bosques, pero el cafe rustico (cultivado bajo dosel de bosque nativo) sustento la mayor perdida de especies, y la perdida de especies de hormigas, aves y arboles de bosque aumento con la intensificacion del manejo. Las perdidas de especies de hormigas y aves fueron similares, aunque las perdidas de hormigas de bosque fueron mas drasticas en el cafe rustico. La riqueza de especies de aves migratorias y de aves que forrajean en varios estratos de vegetacion fueron menos afectadas por la intensificacion que las especies residentes de dosel y de sotobosque. Las fincas rusticas protegieron mas especies que otros sistemas cafetaleros, y la perdida de especies dependio mayormente de la especializacion de habitat y de los atributos funcionales. Recomendamos que el bosque sea protegido, se promueva el cafe rustico y se restauren las fincas intensivas mediante el incremento de la densidad y riqueza de arboles nativos y permitiendo el crecimiento de epifitas. Tambien recomendamos que las futuras investigaciones enfoquen las compensaciones potenciales entre la conservacion de la biodiversidad y la forma de vida de los campesinos que producen cafe.

We compared soils under recently established J. virginiana forests and adjacent native C sub(4)-dominated grassland to assess changes in potential soil nitrogen (N) transformations and plant available N. Over a 2-year period, concentrations of extractable inorganic N were measured in soils from forest and grassland sites. Potential gross N ammonification, nitrification, and consumption rates were determined using super(15)N isotope-dilution under laboratory conditions, controlling for soil temperature and moisture content. Potential nitrification rates (V sub(max)) and microbial biomass, as well as soil physical and chemical properties were also assessed. Extractable NH sub(4) super(+) concentrations were significantly greater in grassland soils across the study period (P <= 0.01), but analysis by date indicated that differences in extractable inorganic N occurred more frequently in fall and winter, when grasses were senescent but J. virginiana was still active. Laboratory-based rates of gross N mineralization (ammonification) and nitrification were greater in grassland soils (P <= 0.05), but only on one of four dates. Potential nitrification rates (V sub(max)) were an order of magnitude greater than gross nitrification rates in both ecosystems, suggesting that nitrification is highly constrained by NH sub(4) super(+) availability. Differences in plant uptake of N, C inputs, and soil microclimate as forests replace grasslands may influence plant available N in the field, as evidenced by seasonal differences in soil extractable NH sub(4) super(+), and total soil C and N accumulation. However, we found few differences in potential soil N transformations under laboratory conditions, suggesting that this grassland-to-forest conversion caused little change in mineralizable organic N pools or potential microbial activity.

Field observations of Rima Hadley by Apollo 15 indicate that lunar rilles are volcanic in origin. However, eruption parameters and emplacement processes necessary for rille formation are not completely understood. Rilles often exhibit a meandering channel, u-shaped, v-shaped, or flat floors, and no levees or thickened flow margins. Channel widths tend to narrow downstream and lack well-defined lobes extending from the terminus. Based on the scarcity of thick flow margins on the lunar surface: Why do lunar eruptions preferentially form rilles? What are the eruption parameters, emplacement processes (erosion, construction, inflation), and flow dynamics of lunar lavas that result in observed rille morphologies? Here, we investigate Vallis Schroeteri, the largest rille on the Moon, which originates toward the center of Aristarchus Plateau. Three key morphologic features define Vallis Schroeteri: the cobra-head, primary rille, and inner-rille. Surrounded by a approximately 1000-m-high mound of material at the source vent, the primary rille extends for 125-km, with outcrops of lava flows exposed in the upper walls. An inner-rille, with tight, gooseneck meanders, carves into the flat floor, cross cuts the distal wall of the primary rille and extends for an additional 40-km towards Oceanus Procellarum. These complex stratigraphic and morphologic relationships are not well explained by a single, existing model of rille formation and yield several questions to consider. How did the cobra-head mound originate? Was the primary rille's path influenced by pre-flow topography? Why does the inner-rille have tight gooseneck meanders? We will present scenarios involving both volcanic erosion and volcanic construction processes to explain the morphology of Vallis Schroeteri based on observations of terrestrial volcanic eruptions. A renewed study of Vallis Schroeteri and rilles in general using data from current and upcoming missions will provide insight to their origin.

The Dunkard, the youngest Paleozoic strata in the Appalachian Basin, is comprised of sandstone, shale, mudstone, and minor amounts of limestone and coal. Relatively fine-grained, texturally and mineralogically immature sandstones, tend to have flat, non-erosional, bases. Strata interpreted as paleosols consist of both calcic and noncalcic Vertisols, and coal beds. Megascopically, shales contain substantial amounts of unweathered biotite and muscovite mica. Thin brecciated limestones lack any indication of marine origin. Dunkard strata are virtually devoid of any indication of marine influence. Characteristics of Dunkard Group strata are indicative of the following: 1) tectonic control on basin configuration, 2) restricted chemical weathering and a long-term dry subhumid paleoclimate, 3) depositional systems decoupled from sea level, 4) lake levels and water chemistry controlled by cyclic variations in rainfall, 5) decreasing occurrence of coal and increasing numbers of calcic paleosols up-section indicative of progressive long-term drying, 6) base level and sedimentary cycles driven solely by climate. Stratigraphic patterns within the Dunkard Group appear to be consistent with the better understood Pennsylvanian climate cycles. Tectonic uplift and/or low sea levels induced by Permian ice volume decoupled water levels within the basin from eustatic sea level fluctuations. Thus, dry periods associated with high stands and reduced ice volume, as in the Pennsylvanian, resulted in dry subhumid climates and calci paleo-Vertisols in the Dunkard when the basin dried and lakes disappeared. In contrast, pluvial periods associated with increases in ice volume resulted in lacustrine conditions. Rain shadow effects, induced by the rising ancestral Appalachian Mountains in the Early Permian(?), resulted in progressive climate drying in the Appalachian Basin.

For the final stage of the LPIA, integration of newly developed paleo-high-latitude glacigenic and paleotropical marine and terrestrial records document covariance between repeated shifts in inferred paleoprecipitation, pCO (sub 2) , paleotropical SSTs, and extent of Gondwanan glaciation consistent with CO (sub 2) -forcing of climate. Here we present new results from several basins across paleotropical Euramerica (Appalachian Basin, USA; Donets Basin, Ukraine; Paganzo Basin, northwest Argentina) that extend the apparent CO (sub 2) -climate-glaciation link down into the Carboniferous. Integration of soil carbonate delta (super 13) C and delta (super 18) O, fossil plant matter delta (super 13) C and delta (super 15) N, paleosol morphologies, and lithologic trends from Late Mississippian through Pennsylvanian paralic to fully terrestrial successions delineates discrete intervals (2 to 4 Myr) of decreased effective moisture and increased seasonality likely associated with elevated atmospheric pCO (sub 2) . Drier intervals are intercalated with those characterized by humid climate paleosol morphologies and lithologies, significantly lower pedogenic and meteoric calcite delta (super 18) O values, and estimated present-day pCO (sub 2) . Two inferred "drier" intervals (Late Mississippian and latest Moscovian through Kasimovian)--possibly greenhouse gas-forced--coincide with periods of normal marine and fluvio-deltaic sedimentation, or long-lived pedogenesis in high-latitude southern Gondwana, indicating drier periods coincided with periods of glacial minima or possibly ice-free conditions. Integration of our proxy records with tropical paleobotanical records reveals repeated major restructuring of flora in-step with climate and pCO (sub 2) shifts. Notably, major floral shifts documented across the Middle-Late Pennsylvanian boundary and Permo-Carboniferous transition are coincident with mineral isotopic and sedimentologic evidence for increased aridity and seasonality; abrupt shifts in fossil plant isotope values record the impact of these climate transitions on tropical flora.

Before the completion of the Panama land bridge, shallow-water marine environments and their faunas on either side of the isthmus were more similar than they are today. The prediction is that the gradual separation of Caribbean and tropical Eastern Pacific waters resulted in the progressive differentiation of the two faunas. While uplift from the collision of the Panama arc with South America began to affect deep-sea circulation by the upper middle Miocene, and complete deep-water cutoff is generally dated to approximately 8 Ma, the timing of surface-water changes and the resulting divergence of Pacific and Caribbean neritic faunas remains unclear. The present study uses upper Miocene and middle Pliocene benthic foraminifera from inner to outer neritic (<200m) deposits of northwestern Venezuela, Caribbean and Pacific Panama, and coastal Ecuador. The relationships between the assemblages are measured using similarity indices such as Simpson's and Jaccard's. As an additional characteristic of assemblages, the diversity of each sample is measured using Fisher's alpha. Assemblages deposited shortly before and after the approximately 8 Ma deep-water cutoff are compared, as well as those deposited during seaway closure, at approximately 3.5 Ma.

The baseline study was in 1975/1976. and 2005 re-sampling showed that the mean foraminiferal density declined 83% from 1975/1976 levels (from 280 foraminifers per 20 ml of sediment to 46 in 2005). Similarly, the number of species declined by 79%; from 62 to 13 species in 2005. Additionally, a dramatic increase in the dominance of Ammonia was also observed; increasing from 42% of the total fauna in 1975/1976 to 76% in 2005. Based upon this 2005 data, a three-stage evaluation system of ecosystem decline over time was proposed with St. Lucie area nearing the beginning of Stage 3 (local extinction). Stage 1 is associated with increased foraminiferal density and species richness, and Stage 2 is marked by their decreasing values. Here we present a new 2007-08 dataset from the same area. In 2007, we observed a mean foraminiferal density of 98 per 20 ml, an increase of 213% from 2005 levels and in 2008, of 114, an increase of 16% from 2007 levels. Additionally, in 2007 we observed 26 species, an increase of 100% from 2005 levels and 57 in 2008, an increase of 219% from 2007 levels. Similarly, the most abundant species decreased from a high of 76% in 2005 to 71% and 64% in 2007 and 2008 respectively. Thus, these preliminary data suggest that by summer of 2008, St. Lucie area had improved considerably and reverted to Stage 1 of the three-stage evaluation system, approaching 1975-76 levels.

The large-sized species T. eubejaouaensis and H. trocoidea and several other species bearing well developed and distinctive pore mound wall textures go extinct at this boundary. Although the rate of species turnover across this extinction event is poorly constrained, due in large part to widespread taxonomic inconsistencies and incomplete species lists, a dramatic reduction in species diversity associated with decreases in shell size and shell wall thickness among descendants have been widely reported. Our taxonomic investigation of this turnover event involves study of well preserved Aptian-Albian foraminifera from five deep-sea sites in the subtropics and southern high latitudes. We estimate that at least 70% of species present in the late Aptian did not survive into the Albian, and lowest Albian assemblages consist almost entirely of two, tiny trochospiral species, one of which is described as new. In addition, stable isotopic analyses of pristinely preserved foraminifera from ODP Site 1049 reveal that the turnover event is associated with a negative shift in carbon isotope values but little change in benthic or planktonic foraminiferal oxygen isotopes. Paleotemperature estimates are quite cool, with middle bathyal temperatures ranging from 9 to 11 degrees C and sea-surface temperatures estimated as 13 to 16 degrees C, and the vertical oxygen and carbon isotopic gradients are quite low, ranging between 2 and 4 degrees C. A minimum in (super 87) Sr/ (super 86) Sr values near the time of the Aptian-Albian boundary suggests increased ocean crust production. Furthermore, a sharp drop in foraminiferal Mg/Ca ratios across this boundary suggests increased hydrothermal activity leading to a secular change in ocean carbonate chemistry, which may have been partially responsible for the dramatic planktonic foraminiferal extinction event.

The study area is Florida Bay, part of Everglades National Park. Current efforts to restore the park and surrounding ecosystems to an original state are being guided by investigations of the natural range of ecosystem variability, the purpose of this study. Eight cores collected from four locations across Florida Bay were examined. Ages of sediments were determined with 210Pb for the last 100-150 years, and 14C for older samples. Benthic foraminifera >63um were identified from 180 samples. There are three basic approaches: 1) The percent abundance of seagrass-associated foraminifera is used to reconstruct historic fluctuations of seagrass abundance. 2) To study salinity change, the alternation between brackish (0-18 ppt) and marine (18-40 ppt) species is documented. 3) Sea-level change is interpreted from the variability in nearshore, lake, mudbank and mangrove faunas associated with different water depths. Preliminary results show the following: 1) Concurrent with a large seagrass die-off in the late 1980's-early 1990's, all cores show decreases in the percent of seagrass-associated benthic foraminifera, as well as foraminifera in general, and increases after 1995. 2) All cores show decreasing salinity in the 1970's and increasing salinity in the 1980's, possibly related to a multi-year drought. Before 1900 there were large variations in salinity between decades. In the 1900's changes were more gradual and may be related to the construction of the Flagler Railroad, hurricanes and canal construction. 3) The dominance and rapid decline of a mangrove fauna about 4,000 years ago reflects the entry of seawater into Florida Bay. Further analysis is needed to identify trends and relate them to seagrass and salinity variations.

Each site was subjected to SHE analysis, an information-theoretic method of biofacies identification and analysis of community structure. Preliminary results indicate that at bathyal-abyssal depths in the Caribbean, changes in the overall benthic foraminiferal species diversity were minor. In contrast, changes in benthic foraminiferal community structure are easily recognized at around 4.2 Ma, the approximate time of the CAS closure. Additionally, the community structure within the Colombian Basin changed at both Sites 999a and 502a before the CAS closure, but the events were asynchronous. After the closure no further oceanographic events disrupted community structures. Thus, this study demonstrates that oceanographic events are easily recognizable through changes in community structure even when changes in traditional proxies are minor.

These include the Samana Peninsula HP melange (Dominican Republic), Cordillera de la Costa HP melange (Venezuela), Roatan amphibolite (Honduras), as well as the Las Ovejas and El Tambor Formations (Chortis Block, Guatemala). Lithological associations for both the Samana Peninsula and Cordillera de la Costa HP melanges are similar with mafic eclogitic boudins hosted in marble, mica schists, and minor serpentinite. The mafic rocks in both suites have very similar geochemistry. Thus, they may originally be part of the same terrane that is now exposed on both sides of the Caribbean Plate. Other portions of Caribbean subduction complexes and metamorphic basement were metamorphosed and exhumed earlier, ranging from 144 Ma in the Sinua HP melange (Nicaragua), 116 Ma in the HP melange (Chortis Block, Guatemala), 88-55 Ma in the HP melange (Maya Block, Guatemala), 123-103 in western Cuba, and 85-60 in central and eastern Cuba, 104-64 Ma in the Rio San Juan HP Complex (Dominican Republic), 67 Ma in Jamaican blueschist, 90-79 Ma in the Villa de Cura Group (Venezuela), and 90-80 Ma in Margarita Island (Venezuela). The spread in peak metamorphic and exhumation ages along the Caribbean margin implies a very long-lived subduction zone in some portions and multiple subduction events in other portions. The Eocene-Oligocene exhumation of these HP terranes is probably related to a short-lived change in the relative motion of the Caribbean from strike-slip to north-south collision. This may have caused subduction roll back and triggered the final ascent of these terranes on both the northern and southern margin of the Caribbean.

The overarching goal is to show the extent and complexity of lava flow emplacement associated with small volcanic vents from the ground perspective versus observations from remote sensing images and apply this to the interpretation of lava flows on other planetary bodies. Field objectives include: 1) traverse planning and navigation using satellite images and maps, 2) topographic data collection using Differential Global Positioning System (DGPS) and LIDAR, and 3) identification of different flow units and textures. Data sets available are: Landsat, Shuttle Radar Topography Mission (SRTM), topographic and geologic maps, plus web-based and software programs (Google Earth, TOPO!). Several data sets are available for the Moon (LO, Apollo, Clementine, KAGUYA) and Mars (THEMIS, CTX, MOC, HiRISE) over a range of resolutions. In the field, participants can: 1) plan a traverse to the vent source to document the morphology of the cinder cone using a DGPS and/or LIDAR, 2) identify "morphologic zones" in the remote sensing images and then identify these zone boundaries in the field, and 3) reconstruct the sequence of events and flow processes necessary to explain the observed stratigraphy at certain locations. Students can compare regional data sets to the field data to see the value and limitations (DGPS profiles versus SRTM profiles). The McCartys flow provides insight into the complexity of compound flows, the influence of inflation on modeling eruption parameters, and the development of volcanic fields from small volcanic vents, all of which provide a basis for comparison of volcanic processes between planetary bodies, particularly the Moon and Mars.

A field study of a paleo-pluvial lake was conducted April 14 to 19, 2008, in the southern end of Surprise Valley, which extends across the Nevada-California border. Distinct linear features that parallel the topographic contours of the ridges bounding the valley are evident in both remote sensing images and from the roadside. We collected 900 positional points along ten transect lines using a Trimble R8 Differential Global Positioning System (DGPS), tied to a published USGS reference elevation, which facilitates correlation of shoreline elevations to <0.5 m across the 8.5 km width of the valley. Each transect crossed a series of paleo-shorelines expressed as terraced benches along the valley walls. The morphologic expression of some shorelines can vary over horizontal distances <100 meters, likely influenced by variations in local bedrock and soil development, whereas some shorelines can be correlated around the entire southern end of Surprise Valley. Tufa accumulations on and around cobbles and boulders are very pronounced along at least two shorelines. The western valley wall has a steep slope with the highstand and tufa deposits comprising the most prominent shorelines. The eastern valley wall has a gentle slope with several shorelines, including the highstand and tufa shorelines. Student activities could involve mapping shorelines on satellite images, field identification of the lake highstand, interpretation of the asymmetric slopes of the valley walls, and identification and discussion of tufa. The data obtained from the investigation in Surprise Valley should be applicable as primary referents for evaluating the possibility of a pluvial origin for features observed inside some large impact crater basins on Mars.

It is a major mining district for nickel, copper, and platinum group elements, and thought for many decades to be an igneous structure. However, it was proposed by R. S. Dietz in 1964 on the basis of predicted shatter cone occurrences that the structure was an impact crater, a theory shortly after confirmed by B. M. French on the basis of shock features in the breccias. Recent research by French and others has called attention to the importance of carbon in the Onaping Formation, with possible biological implications. The Sudbury Structure was used as a training site for the Apollo 16 astronauts in 1971, and enabled them after landing on the Moon to instantly recognize the Cayley Formation as impact breccia rather than volcanic rock. We suggest that the Sudbury Structure be considered as a training site for planetary field scientists. We recommend this site to educators who wish to expose students to terrestrial examples of processes and rocks probably analogous to features seen on planetary remote sensing data. The geology is now thoroughly mapped and extremely well-exposed, and the entire Structure easily accessible by road. The greater Sudbury area has several universities and an office of the Ontario Geological Survey, and is served by scheduled air lines. It therefore is recommended as an analog site for training future planetary geology students.

We assess the consequences of a niche expansion by Mexican jays (Aphelocoma ultramarina) along an elevation gradient. We predicted that jays at high elevation would have straighter bills adapted to feeding on pine cones, whereas jays at low elevation would have hooked bills adapted to feeding on acorns. We measured morphological and genetic variation of 95 adult jays and found significant differences in hook length between elevations in accordance with predictions, a pattern corroborated by analysis at the regional scale. Genetic results from microsatellite and mtDNA variation support phenotypic differentiation in the presence of gene flow coupled with weak, but detectable genetic differentiation between high- and low-elevation populations. These results demonstrate that niche expansion can lead to adaptive divergence despite gene flow between parapatric populations along an elevation gradient, providing information on a key precursor to ecological speciation.

Their current distribution on isolated southern land masses is believed to reflect the breakup of the paleocontinent of Gondwana. The prevailing view is that ratites are monophyletic, with the flighted tinamous as their sister group, suggesting a single loss of flight in the common ancestry of ratites. However, phylogenetic analyses of 20 unlinked nuclear genes reveal a genome-wide signal that unequivocally places tinamous within ratites, making ratites polyphyletic and suggesting multiple losses of flight. Phenomena that can mislead phylogenetic analyses, including long branch attraction, base compositional bias, discordance between gene trees and species trees, and sequence alignment errors, have been eliminated as explanations for this result. The most plausible hypothesis requires at least three losses of flight and explains the many morphological and behavioral similarities among ratites by parallel or convergent evolution. Finally, this phylogeny demands fundamental reconsideration of proposals that relate ratite evolution to continental drift.

The systematics of nine bivalve species previously reported from these deposits can now be reevaluated using newly collected fossils. The fossils include a Cenomanian specimen of Nucinella gigantea with a drill hole possibly made by a naticid, by far the oldest record of a drill hole from a cold seep site. In Japan, Cretaceous seep bivalve assemblages are characterized by (i) the unique occurrence of large specimens of Nucinella (Manzanellidae), (ii) the commonly present nuculid Acila (Truncacila), and (iii) a high diversity of lucinids, possibly as many as four distinct genera. Two new species described are the Albian Acharax mikasaensis (Solemyidae) and the Albian to Campanian Thyasira tanabei (Thyasiridae), of which the former had previously been misidentified as the oldest vesicomyid, the latter as the oldest Conchocele.

The association of submarine silicic calderas with thick proximal accumulations of pumice lapilli suggests that these pyroclasts were deposited as a direct result of submarine eruptions. Yet when first erupted, these highly vesicular, gas-filled clasts had densities significantly less than seawater. Experiments carried out 1-atm on heated pumice samples whose vesicles were charged with steam, the dominant component of magmatic volatiles show that buoyancy of freshly erupted submarine pumice is transient. Upon quenching, the phase change of steam-to-liquid water creates strong negative pore pressures within the pumice vesicles that accelerate the absorption of surrounding water, generating high-density pumice and promoting rapid clast sinking. Variations in the physical properties of steam with temperature and pressure have important implications for submarine pyroclastic eruptions. Firstly, highly vesicular pumice can be deposited on the seafloor at temperatures elevated significantly above ambient if they are erupted at sufficient depths to remain wholly submarine (> nearly equal 200 m) and either the fluid in which they cool contains heated water and/or they only absorb sufficient water to sink. Secondly, the rapid increase in density of the eruption column caused by condensation and the transition from buoyant (gas-filled) to denser (water-saturated) pumice lapilli, together with turbulent mixing with the surrounding seawater favour collapse and transport of pyroclasts in water-supported gravity currents. Finally, this mixing of the ejecta with seawater and the ease of water ingestion into permeable pumice clasts suggest that water-supported transport mechanisms can operate as primary dispersal processes in explosive submarine eruptions.

The Kibish Formation has yielded a diverse mammalian fauna (as well as birds and crocodiles), stone tools, and the oldest anatomically modern Homo sapiens. Fish, the most common vertebrate fossils in this unit, are reported in this study. Catfish (especially clariids and Synodontis) and Nile perch (Lates niloticus) predominate, but the gymnarchid Gymnarchus, a cyprinid (Barbus), tigerfish (Hydrocynus), pufferfish (Tetraodon), and other catfish are also present. In total, nine teleost genera are found in the Kibish Formation, representing a subset of the 37 genera that constitute the modern Omo-Turkana ichthyofauna. Several taxa present in the modern fauna, including Polypterus and members of the family Cichlidae, are not found in the Kibish deposits. Most specimens are preserved as disarticulated or broken skeletal elements, but some preservation of articulated elements (e.g., sets of vertebrae, crania with lower jaws or cleithra) also occurs. Many of the catfish and Nile perch specimens are larger than the largest reported from the modern river or lake. Faunas of Kibish Members I and III closely resemble one another; the fauna from Member IV contains only the three most common taxa (Clarias, Synodontis, Lates), though this may result from insufficient sampling. Barbed bone points have been collected from the upper part of the formation, indicating a long association between the human inhabitants and the fish fauna of the Omo Valley.

A diverse assemblage of large mammals, including many species of bovids, suids, and equids, has been recovered from the Kibish Formation. There are no extinct large mammals represented in the fossil assemblage, and the overall taxonomic composition of the fossil fauna is similar to the modern-day wildlife community living near the Omo River. The fossil faunal assemblage shows a paucity of arboreal primates, and carnivore species are rare. However, the faunal sample includes possible Cephalophus (duiker) remains and Hylochoerus meinertzhageni (giant forest hog), taxa that are extremely rare in the African fossil record, and both indicate more closed habitats. Comparative analyses of the Kibish faunal remains using the ecological-diversity approach document close associations with edaphic grassland and woodland vegetation types. These vegetation forms are similar to current habitats surrounding the Omo River.

We explored these linkages by comparing shallow (5-20cm) soil properties along groundwater flowpaths in two rich fens, a marl fen, and a poor fen. Organic matter content, bulk density, and total elemental content varied more with depth to underlying drift materials than with water table fluctuation, but also were influenced by groundwater discharge, which stabilized water table elevations and controlled redox conditions. Total sulfur and calcium content increased where pore-water chemistry indicated active iron and sulfate reduction. Calcium mineral dynamics, however, did not appear to influence P availability: first, calcium carbonate (CaCO sub(3)) accounted for <2% of the soil composition, except in the marl fen where it accounted for 20-25% of the soil composition. Second, Ca-bound P pools, determined from hydrochloric extraction of wet soil samples, accounted for <25% of the inorganic soil P pool. In contrast, iron-bound P determined from bicarbonate-buffered dithionite solution, accounted for 50-80% of the inorganic soil P, and increased where there was evidence of groundwater mixing, as did P release rates inferred from incubated anion resin bags. The total carbon and phosphorus content of organic-rich soils as well as available and labile P pools were strongly correlated with pore-water iron and alkalinity concentrations. Groundwater discharge and resulting hydrochemical gradients explained significant variation in soil composition and P availability across each site. Results highlight the importance of conducting biogeochemical studies in the context of a site's shallow geologic setting and suggest mechanisms supporting the diverse plant species unique to groundwater wetlands.

The reproductive compensation hypothesis assumes that (i) pathogens and parasites evolve more rapidly than their hosts, (ii) mate preferences predict variation in health and viability of offspring, (iii) social and ecological factors keep some individuals from mating with their preferred partners (some are constrained to mate with partners they do not prefer), (iv) all individuals may be induced to compensate, so that (v) variation in compensation is due to environmental and developmental factors affecting between-individual abilities to express compensatory mechanisms. Selection favouring compensation may act through variation in prezygotic physiological mechanisms, zygotic mechanisms, or parental care to eggs or young that enhance offspring health, increasing the likelihood that some offspring survive to reproductive age, often at a survival cost to the parents. Compensation may be through increased number of eggs laid or offspring born, a compensatory effort working during a single reproductive bout that sometimes will match the number of offspring surviving to reproductive age produced by unconstrained parents during the same bout. The reproductive compensation hypothesis therefore predicts trade-offs in components of fitness for breeders, such that parents constrained to mating with a nonpreferred partner, but who compensate sometimes match their current productivity (number of offspring at reproductive age) to unconstrained parents (those breeding with their preferred partners), and, when all else is equal, die faster than unconstrained parents. The reproductive compensation hypothesis emphasizes that reproductive competition is not just between constrained and unconstrained individuals, but also among constrained individuals who do and do not compensate. The reproductive compensation hypothesis may thus explain previously unexplained between-population and within-population, between-individual variation in reproductive success, survival, physiology and behaviour.

For each species, 30 individuals, 10 each in three secondary forests, were monitored monthly for four years at the Biological Dynamics of Forest Fragments Project, north of Manaus. Five species showed nearly continuous flowering and fruiting throughout the study, indicating that resources were available to pollinators and dispersers on a regular basis. The other eight species showed stronger seasonality in reproduction, seven of them annually, and one supra-annually. Overall, flowering was concentrated in the transition from the dry to the rainy season and fruiting was concentrated in the rainy season. There was no relationship between reproductive phenology and tree pollinator type or dispersal mode. Reproductive phenology was remarkably consistent year to year. The pioneer community showed a variety of phenological patterns but as a whole tended to be characterized by annual flowering and fruiting, either continuously or seasonally, thereby fitting generalizations of pioneer species relative to mature forest species.

It remains unclear, however, whether other areas may have served as important glacial refugia. Moreover, many such species exhibit widespread genetic similarity within eastern and western regions because of recent expansion from small refugial populations, making it difficult to evaluate current-day levels of gene flow. In this study, we used mitochondrial DNA (mtDNA) control region sequence and amplified fragment length polymorphism markers to survey genetic variation in a widespread migratory bird, the American redstart (Setophaga ruticilla). mtDNA analyses revealed a pattern that contrasts with that found for most other widespread species studied to date: most redstart populations across North America appear to have spread out from a single glacial refugium, possibly located in the southeastern United States, whereas populations in far-eastern Canada may have survived in a second glacial refugium located on the now-submerged Atlantic coastal shelf off the coast of Newfoundland. A pattern of isolation by distance in mtDNA suggested some constraints on current-day gene flow among extant redstart populations. This study thus reveals a recent evolutionary history for this species that differs from that of most other widespread North American passerines and provides evidence for limited gene flow in a species with potentially large dispersal distances.

Using this approach, we determined the Maastrichtian-Cenozoic polyphase growth of the Eastern Cordillera of Colombia, an inverted Mesozoic extensional basin. The record of this growth occurs in an Andean (post-middle Miocene) thrust belt (the Eastern Cordillera) and in adjacent foreland basins, such as the Llanos Basin to the east. This approach permitted the identification of five tectono-stratigraphic sequences in the foreland basin and five phases of shortening for the Eastern Cordillera. Thermo-chronological and geochronological data support the spatial and temporal evolution of the orogen-foreland basin pair. Tectono-stratigraphic sequences were identified in two restored cross sections, one located at a salient and the other in a recess on the eastern flank of the Eastern Cordillera. The lower two sequences correspond to late Maastrichtian-Paleocene flexural events and record the eastward migration of both tectonic loading and depositional zero in the Llanos Basin. These sequences consist of amalgamated quartzarenites that abruptly grade upward to organic-rich fine-grained beds and, to the top, light-colored mud-stones interbedded with litharenites in isolated channels. Amalgamated conglomeratic quartzose sandstones of the third sequence record ~15 m.y. of slow subsidence in the Llanos Basin and Llanos foothills during early to middle Eocene time, while shortening was taking place farther west in the Magdalena Valley. The fourth sequence, of late Eocene-middle Miocene age, records a new episode of eastward migration of tectonic loads and depositional zero in the Llanos Basin. This sequence begins with deposition of thick fine-grained strata to the west, whereas to the east, in the Llanos basin, amalgamated quartzarenites unconformably overlie Cretaceous and older rocks (former forebulge). Apatite fission tracks in the axial zone of the Eastern Cordillera, growth strata in the Llanos foothills, and synextensional strata on the forebulge of the Llanos Basin constrain deformation patterns for this time. The post-middle Miocene Andean event initiated with regional flooding of the foreland basin in response the widening of tectonic loading, after which the foredeep was filled with coarse-grained alluvial and fluvial detritus derived from the Eastern Cordillera. The geometry of tectonic loads, constrained by flexural models, reveals shortening events of greater magnitude for the uppermost two sequences than for pre-middle Eocene sequences. Tectonic loads for the late Maastrichtian-middle Eocene phases of shortening were less than 3 km high and 100 km wide. For the late Eocene-middle Miocene phase, tectonic loads changed southward from 6 km to less than 4 km, and loads were wider to the north. The strong Andean inversion formed today's Eastern Cordillera structural configuration and had equivalent tectonic loads of 10-11 km. Integrated analysis is necessary in polyphase orogenic belts to define the spatial and temporal variation of tectonic load and foreland basin configurations and to serve studies that seek to quantify exhumation and three-dimensional analyses of thrust belts. For the Eastern Cordillera, thermochronological sampling must span the width of the Eastern Cordillera rather than be concentrated in a single range.

The distributions of these species are poorly known, although detailed information could benefit malaria vector incrimination and control. We used published collection records of these species and environmental geospatial data to construct consensus ecological niche models (ENM) of each species' potential geographic distribution. The status of the Indian taxon An. fluviatilis S as a species distinct from An. harrisoni has been debated in the literature, so we tested for differentiation in ecological niche characteristics. The predicted potential distribution of An. minimus is more southerly than that of An. harrisoni: Southeast Asia is predicted to be more suitable for An. minimus, and China and India are predicted more suitable for An. harrisoni, so An. harrisoni seems to dominate under cooler conditions. The distribution of An. minimus is more continuous than that of An. harrisoni: disjunction in the potential distribution of the latter is suggested between India and Southeast Asia. Anopheles fluviatilis S occurrences are predicted within the An. harrisoni ecological potential, so we do not document ecological differentiation that might reject conspecificity. Overall, model predictions offer a synthetic view of the distribution of this species complex across the landscapes of southern and eastern Asia.

Rather than being dominated by rural farmers, tropical deforestation now is substantially driven by major industries and economic globalization, with timber operations, oil and gas development, large-scale farming and exotic-tree plantations being the most frequent causes of forest loss. Although instigating serious challenges, such changes are also creating important new opportunities for forest conservation. Here we argue that, by increasingly targeting strategic corporations and trade groups with public-pressure campaigns, conservation interests could have a much stronger influence on the fate of tropical forests.

AN - 19533811; 8533373 AB - We present results on changes in soil properties following land use change over an approximately 55-year period at Fort Benning, Georgia, U.S.A. Soil cores were taken at 129 locations that were categorized as reforested (field/bare ground in 1944 and forest in 1999), disturbed (field/bare ground in 1944 and 1999), or reference forests (forest in 1944 and 1999). Soil disturbance included historic agriculture (pre-1944) and military training (post-1944). Density in mineral soils exhibited a historic land use legacy effect (reference reforested > disturbed). Soil C stock in all other increments and in particulate organic matter was affected by disturbance; however, no legacy was apparent (reference = reforested > disturbed). For the entire soil profile (O-horizon to 40 cm), rate of C accrual was 28 g m super(-2) yr super(-1) (1.5%/yr). Nitrogen stocks were affected by disturbance in the O-horizon and 0- to 10-cm increment; however, no legacy effect was detected (reference = reforested > disturbed). Nitrogen accumulated at 0.56 g m super(-2) yr super(-1) (0.6%/yr) for the entire soil profile. At Fort Benning, soil C and N stocks of reforested stands were similar to those of reference forested stands after approximately 55 years. However, soil bulk density was greater on reforested stands than reference forest stands at 55 years and may require an additional century to reach reference levels.

The "biogenetic law" and ontogenetic changes in the webs and building behavior of the black widow spider Latrodectus geometricus (Araneae Theridiidae) AN - 19421226; 8807562 AB - Young juveniles of L. geometricus fit the strong trend for "ontogeny to repeat phylogeny" previously documented in other web-building spiders; younger spiders were less likely to build the derived silk retreats that occur at the edges of webs of adults. Younger individuals also consistently built more highly organized webs, with radial lines that converge on a central, horizontal disc and that support regularly spaced, sticky "gumfoot" lines. Some details of how radial and gumfoot lines were built suggest that the radial and gumfoot lines and the behavior involved in their construction may be homologous with traits associated with radii and sticky spirals in aranoid orb webs. The numerous convergences between the webs and building behavior of young L. geometricus and the highly modified webs and building behavior of genera of the orb weaving families Theridiosomatidae (Wendilgarda) and Anapidae (Comaroma), which have independently replaced orbs with webs designed to capture prey on surfaces near the web, suggest a new hypothesis for how gumfoot theridiid webs may have evolved from orbs.

The CO emission peaks around the two merger nuclei with a velocity signature of gas rotation around each nucleus and is also detected in a kiloparsec-size disk encompassing the binary nucleus. The dust continuum, in contrast, is mostly from the two nuclei. The beam-averaged brightness temperature of both line and continuum emission exceeds 50 K at and around the nuclei, revealing the presence of warm molecular gas and dust. The dust emission morphologically agrees with the distribution of radio supernova features in the east nucleus, as expected when a starburst heats the nucleus. In the brighter west nucleus, however, the submillimeter dust emission is more compact than the supernova distribution. The 860 [mu]m core, after deconvolution, has a size of 50-80 pc, consistent with recent 1.3 mm observations, and a peak brightness temperature of [image] K. Its bolometric luminosity is at least [image] L sub([image]) and could be [image]10 super(12) L sub([image]) depending on source structure and 860 [mu]m opacity, which we estimate to be of the order of [image] (i.e., [image]). The starbursting west nuclear disk must have in its center a dust enshrouded AGN or a very young starburst equivalent to hundreds of super star clusters. Further spatial mapping of bolometric luminosity through submillimeter imaging is a promising way to identify the heavily obscured heating sources in Arp 220 and other luminous infrared galaxies.

2011-045404 AB - Geohistorical records reveal the long-term impacts of climate change on ecosystem structure. A 5-myr record of mammalian faunas from floodplain ecosystems of South Asia shows substantial change in species richness and ecological structure in relation to vegetation change as documented by stable isotopes of C and O from paleosols. Between 8.5 and 6.0 Ma, C (sub 4) savannah replaced C (sub 3) forest and woodland. Isotopic historical trends for 27 mammalian herbivore species, in combination with ecomorphological data from teeth, show three patterns of response. Most forest frugivores and browsers maintained their dietary habits and disappeared. Other herbivores altered their dietary habits to include increasing amounts of C (sub 4) plants and persisted for >1 myr during the vegetation transition. The few lineages that persisted through the vegetation transition show isotopic enrichment of delta (super 13) C values over time. These results are evidence for long-term climatic forcing of vegetation structure and mammalian ecological diversity at the subcontinental scale.

The experiments produced a range of mineralogical and compositional changes. Olivine exhibits significant reduction to compositions of Fa (sub 2-5) at temperatures of 1300 degrees C. In contrast, orthopyroxene exhibits only slight reduction until the highest temperatures. Chromite is sometimes consumed by intruding sulfides, and displays increasingly magnesian compositions ranging as low as Fe/Fe+Mg of 0.1 at a constant Cr/Cr+Al ratio. The compositional changes with increasing temperature reflect a complex set of reactions, including oxidation-reduction. One application of these experiments address whether primitive achondrites could have formed from ordinary chondrite-like precursors by partial melting under reducing conditions. While changes observed in olivine and troilite compositions might support such an idea, differences in oxygen isotopic composition, Cr/Cr+Al in chromite, orthopyroxene compositions, and thermodynamic evidence against reduction during melting of primitive achondrites (Benedix et al. 2005) firmly refute such an idea.

Each year, these field notes, photographs, sound recordings and moving images are consulted by anthropologists writing biographies and intellectual histories, conducting comparative research, and reviewing the work of anthropologists who conducted research in the same ethnographic region. These field materials are also increasingly consulted by non-anthropologists, particularly native peoples studying their own cultural heritage. This text discusses some of the challenges involved in collecting ethnographic field notes and making them available to the public both on-site in our archives and online. It also considers the archivist's relationship to source communities, particularly ethical issues relating to the curation of culturally sensitive materials. Adapted from the source document.

This report focuses on the discovery of what look like beads made of opercula of the terrestrial gastropod Revoilia guillainopsis at the Middle Stone Age site of Porc-Epic in Ethiopia. Accelerator mass spectrometry dating of three opercula suggested dates ranging from 33,000-43,000 years ago. Beads made of gastropod shells have been found elsewhere; a sample from the Mediterranean may be more than 100,000 years old, but is not from the same gastropod. While microscopic examination could not confirm that what were found at Porc-Epic were used as beads, the wearing of beads as personal ornaments is thought to distinguish modern humans from their predecessors & is described as a symbolic behavior.

A manuport, a rock fragment carried by human agency to the site, was discovered in a sediment core section north of Burullus lagoon near the Mediterranean coast. Accelerator mass spectrometry (AMS) radiocarbon analysis of plant-rich matter in the mud surrounding the object provides a date calibrated to 3350-3020 B.C., the late Predynastic period. This long thin manuport, formed of dolomite, had not been deposited by the Nile or the sea but was collected and transported from an outcrop exposure positioned at least 160 km south of the core site. The fragile manuport, used for an undetermined function, lay buried at a depth of 7.4 m in dark olive gray mud deposited in a shallow brackish lagoon setting close to a marsh. This fortuitous find documents an early human presence in the middle Holocene wetlands along the delta's paleocoast, a sector where traditional excavation and augering are normally incapable of reaching occupation levels or zones of activity at considerable subsurface depths. Core drilling provides a means to help archaeologists locate undetected and potentially important sites.

Using two published lacustrine pollen records and a climate-vegetation model based on the modern abundance distributions of 154 Neotropical plant families, we demonstrate how family-level counts of fossil pollen can be used to quantitatively reconstruct tropical paleoclimate and provide needed information on historic patterns of climatic change. With this family-level analysis, we show that one area of the lowland tropics, northeastern Bolivia, experienced cooling (1-3 degrees C) and drying (400 mm/yr), relative to present, during the late Pleistocene (50,000-12,000 calendar years before present [cal. yr B.P.]). Immediately prior to the Last Glacial Maximum (LGM, ca. 21,000 cal. yr B.P.), we observe a distinct transition from cooler temperatures and variable precipitation to a period of warmer temperatures and relative dryness that extends to the middle Holocene (5000-3000 cal. yr B.P.). This prolonged reduction in precipitation occurs against the backdrop of increasing atmospheric CO (sub 2) concentrations, indicating that the presence of mixed savanna and dry-forest communities in northeastern Bolivia during the LGM was not solely the result of low CO (sub 2) levels, as suggested previously, but also lower precipitation. The results of our analysis demonstrate the potential for using the distribution and abundance structure of modern Neotropical plant families to infer paleoclimate from the fossil pollen record.

AN - 50619076; 2008-110310 AB - The problem of gradual versus punctuated change within phyletic lineages can be understood in terms of the homogeneity of evolutionary dynamics. Hypotheses of punctuated change imply that the rules governing evolutionary change shift over time such that the normal dynamics of stasis are temporarily suspended, permitting a period of net evolutionary change. Such explanations are members of a larger class of models in which evolutionary dynamics are in some way heterogeneous over time. In this paper, I develop a likelihood-based statistical framework to evaluate the support for this kind of evolutionary model. This approach divides evolutionary sequences into nonoverlapping segments, each of which is fit to a separate evolutionary model. Models with heterogeneous dynamics are generally more complex--they require more parameters to specify--than uniform evolutionary models such as random walks and stasis. The Akaike Information Criterion can be used to judge whether the greater complexity of punctuational models is offset by a sufficient gain in log-likelihood for these models to be preferred. I use this approach to analyze three case studies for which punctuational explanations have been proposed. In the first, a model of punctuated evolution best accounted for changes in pygidial morphology within a lineage of the trilobite Flexicalymene, but the uniform model of an unbiased random walk remains a plausible alternative. Body size evolution in the radiolarian Pseudocubus vema was neither purely gradual nor completely pulsed. Instead, the best-supported explanation posited a single, pulsed increase, followed later by a shift to an unbiased random walk. Finally, for the much-analyzed claim of "punctuated gradualism" in the foraminifera Globorotalia, the best-supported model implied two periods of stasis separated by a period of elevated but not inherently directional evolution. Although the conclusions supported by these analyses generally refined rather than overturned previous views, the present approach differs from those prior in that all competing interpretations were formalized into explicit statistical models, allowing their relative support to be unambiguously compared.

Despite this ecological and physiological diversity, the results of this study demonstrate that heterogeneity within families does not prevent climatic generalizations at higher taxonomic ranks. Modelled distributions that incorporate local abundance data can discriminate climatically among many plant families and can potentially be used to reconstruct palaeoclimate from sub-fossil and fossil pollen assemblages. Presented are four probabilistic models of temperature and precipitation generated using published transect data of the spatial distributions of 154 Neotropical plant families and the Gaussian kernel probability densities of their occurrence (presence-absence), absolute abundance (density), proportional abundance (dominance), and basal area. Thirty-five published pollen surface samples, representing contemporary Central and South American lowland vegetation, were used to test the accuracy of the modelled climate estimates. The models are able to identify relative differences in temperature and precipitation, with absolute and proportional plant family abundances providing the most accurate estimates. There was little statistical difference among the different models and weighting methods used. The accuracy of individual estimates was more dependent on the number of pollen assemblage families shared with the modern vegetation dataset than any other investigated variable. Family-based climatological proxies have several advantages over assemblage or biome-based reconstructions. Climatic estimates can potentially be derived even when novel combinations of taxa are observed in the fossil record, extending the utility of models based on plant family distributions to palaeobotanical data from deeper time. The approach is also dynamic. Plant communities do not need to be in equilibrium and individualistic dynamics can be incorporated into estimates. Finally, the models provide working hypotheses of how individual species may respond to climatic change based on the climatic specialization of their respective families.

We experimentally examined the Fe-C system at a pressure of 5 GPa and determined the Fe-C phase diagram at this pressure. In addition, we measured solid metal/liquid metal partition coefficients for 17 trace elements and examined the partitioning behavior between Fe (sub 3) C and liquid metal for 14 trace elements. Solid metal/liquid metal partition coefficients are similar to those found in one atmosphere studies, indicating that the effect of pressure to 5 GPa is negligible. All measured Fe (sub 3) C/liquid metal partition coefficients investigated are less than one, such that all trace elements prefer the C-rich liquid to Fe (sub 3) C. Fe (sub 3) C/liquid metal partition coefficients tend to decrease with decreasing atomic radii within a given period. Of particular interest, our 5 GPa Fe-C phase diagram does not show any evidence that the Fe-Fe (sub 3) C eutectic composition shifts to lower C contents with increasing pressure, which is central to the previous reasoning that the inner core may be composed of Fe (sub 3) C.

Primary igneous anhydrite and a larger "excess gas release" of nearly equal 20 million tons of SO (sub 2) were noted for the significantly larger eruption of Mount Pinatubo in 1991, for which a separate gas phase at nearly equal 7-9 km depth was also required by the sulfur budget. Pumices from both eruptions have mineral assemblages dominated by plagioclase and hornblende, with minor biotite, and show evidence for co-nucleation and mutual inclusions of anhydrite and apatite. Both magmas were also very water-rich and highly oxidized, with oxygen fugacities $1 log unit above the synthetic Ni-NiO buffer. Furthering the similarities between these two eruptions, ion-microprobe analyses of sulfur isotopic compositions of anhydrites in pumices from El Chichon and Mount Pinatubo both showed that individual crystals are isotopically homogeneous, but inter-crystalline variations in delta (super 34) S are well beyond analytical error. This study reviews the history of thought regarding primary igneous anhydrite. Ten volcanic and plutonic analogs to the El Chichon and Mount Pinatubo magmas are discussed. All were similarly water-rich and highly oxidized magmas. Hornblende is the dominant mafic phenocryst in all but one plutonic example; in that case so much early anhydrite precipitated that no calcium remained to form hornblende. Biotite is very abundant in that exceptional plutonic case, and is present in six of the other examples with primary igneous anhydrite. Sphene is known as an indicator mineral of high magmatic oxygen fugacity; it was present in the 1982 El Chichon pumices, and in 6 of the other anhydrite-bearing samples. Hornblende and biotite phenocrysts are also characteristic of the intermediate-to-felsic plutonic rocks that typically host porphyry-Cu deposits. Such magmas are also known to be water-rich and highly oxidized. A close spatial and petrogenetic connection exists between magmas with primary igneous anhydrite and magmatic-hydrothermal ore deposits.

Skeletal tissue samples from 135 individuals from an early nineteenth century Philadelphia cemetery (First African Baptist Church) were studied by electrothermal atomic absorption spectrometry and X-ray fluorescence for lead content. High bone lead levels led to investigation of possible diagenetic effects. These were investigated by several different approaches including distribution of lead within bone by X-ray fluorescence, histological preservation, soil lead concentration and acidity as well as location and depth of burial. Bone lead levels were very high in children, exceeding those of the adult population that were buried in the cemetery, and also those of present day adults. The antemortem age-related increase in bone lead, reported in other studies, was not evidenced in this population. Lead was evenly deposited in areas of taphonomic bone destruction. Synchrotron X-ray fluorescence studies revealed no consistent pattern of lead microdistribution within the bone. Our conclusions are that post-mortem diagenesis of lead ion has penetrated these archaeological bones to a degree that makes their original bone lead content irretrievable by any known method. Increased bone porosity is most likely responsible for the very high levels of lead found in bones of newborns and children. Copyright John Wiley & Sons. Reproduced with permission.

The War in the Pacific National Historical Park, which occupies seven parcels of land on the small island of Guam, celebrates the 'freedom' that the U.S. brought to the region in World War II. But in fact, this landscape sits at the nexus of several contested territories. Guam was seized in the 1898 Spanish-American War-the final wave of American territorial expansion-and experienced 50 years of dictatorship under the U.S. Navy, despite vigorous efforts by islanders to gain citizenship and basic rights. The post-war transformation of the island by the military came at the further expense of local land rights, and the park itself later got caught up in the struggle over federal land ownership. Disagreements within the park service and between the park service and the local people added to the contests. Finally and most importantly, the park-as-text presents a discourse of American military heroism against the Japanese, at the expense of recognition of Chamorro suffering, or of any historical marker tying the indigenous history of Guam into U.S. historical memory. The contradiction between U.S. expansionism and U.S. ideals is apparent in the way the park serves as a colonial tool in this remnant of the American empire. This paper examines the park as a narrative landscape within the fields of contestation that characterize U.S. rule on Guam. All rights reserved, Elsevier JF - Political geography AU - Herman, R.D.K.

Seed production was suppressed under shrub canopies, in the open areas between shrubs, or both by applying an herbicide prior to seed set in large, randomly assigned removal plots (10-30 m diameter). Seedlings were censused along transects crossing the reproductive suppression borders shortly after germination. Dispersal kernels were estimated for Pectocarya recurvata and Schismus barbatus from the change in seedling densities with distance from these borders via inverse modeling. Estimated dispersal distances were short, with most seeds traveling less than a meter. The adhesive seeds of P. recurvata went farther than the small S. barbatus seeds, which have no obvious dispersal adaptation. Seeds dispersed farther downslope than upslope and farther when dispersing into open areas than when dispersing into shrubs. Dispersal distances were short relative to the pattern of spatial heterogeneity created by the shrub and open space mosaic. This suggests that dispersal could contribute to local population buildup, possibly facilitating species coexistence. Overall, these results support the hypothesis that escape in time via delayed germination is likely to be more important for desert annuals than escape in space.

In large measure these advances are attributable to new methods for documenting domestication in plants and animals. The initial steps toward plant and animal domestication in the Eastern Mediterranean can now be pushed back to the 12th millennium cal B.P. Evidence for herd management and crop cultivation appears at least 1,000 years earlier than the morphological changes traditionally used to document domestication. Different species seem to have been domesticated in different parts of the Fertile Crescent, with genetic analyses detecting multiple domestic lineages for each species. Recent evidence suggests that the expansion of domesticates and agricultural economies across the Mediterranean was accomplished by several waves of seafaring colonists who established coastal farming enclaves around the Mediterranean Basin. This process also involved the adoption of domesticates and domestic technologies by indigenous populations and the local domestication of some endemic species. Human environmental impacts are seen in the complete replacement of endemic island faunas by imported mainland fauna and in today's anthropogenic, but threatened, Mediterranean landscapes where sustainable agricultural practices have helped maintain high biodiversity since the Neolithic.

A key example is Littorina littorea, the most abundant intertidal snail in northeastern North America. Native to Europe, the snail's ecological history in North America has been debated for over 100years with no definitive resolution. To resolve its cryptogenic status, we used molecular genetics from a novel combination of the snail and a highly associated trematode parasite, Cryptocotyle lingua. Based on mitochondrial sequences of 370 L. littorea and 196 C. lingua individuals, our results demonstrate a significant reduction in genetic diversity in North America vs. Europe, North American haplotypes nested within European haplotypes, and mean divergence estimates of ~500years ago from Europe for both host and parasite - thus supporting a recent introduction of both host and parasite to North America from Europe. Our study therefore resolves not only a specific cryptogenic history, but it also demonstrates the success of our approach generally and could be used in resolving difficult invasion histories worldwide.

Experiments were designed to characterize the formation, survival, and attachment of free-swimming stages (telotrochs) and to assess whether telotrochs preferentially attach to primary (Acartia tonsa and Eurytemora affinis) or alternate hosts from the zooplankton community (the rotifer Brachionus plicatilis, barnacle nauplii, polychaete larvae, and a harpacticoid copepod). The results showed that telotroch formation started 2h after the death of the host, with >90% of the zooids leaving the host carapace within 7h. Formation of telotrochs was triggered only by the death of the host, failing to occur when the host was injured or unable to swim. Telotrochs failed to attach to non-living substrates and survived for only 14h in the absence of host organisms, suggesting that members of Z. intermedium are obligate epibionts. Attachment success decreased with telotroch age, indicating that colonization success in nature may strongly depend on the ability to find a suitable host in a short period of time. Individuals exhibited no preferences in colonizing juvenile or adult stages of A. tonsa or E. affinis. While telotrochs were able to colonize barnacle nauplii and the harpacticoid copepod in the absence of individuals of A. tonsa or E. affinis, they did not attach to the rotifers or polychaete larvae. Telotrochs preferentially colonized individuals of A. tonsa when in the presence of other non-calanoid host species.

In this study, we assessed the status of the S. galeatus population in Las Perlas and Coiba Archipelagos. Average densities per site were dismal: 0.45 plus or minus 3.8 ind.ha-1 and 6.0 plus or minus 18 ind.ha-1 in Las Perlas and Coiba, respectively. In Las Perlas, low densities occurred on the southwest coast of Del Rey, the south coast of Chaperas, and Bolanos, whereas intermediate densities were found on the eastern coast of Saboga. In Coiba, high relative densities occurred only on the west coast of Coiba Island and at the north and south of Bahia Damas. Environmental variability and depth did not explain the differences found between densities nor the low abundances in the archipelagos. Shell length of S. galeatus from Coiba ranged from 91.0-213.3 mm (156 plus or minus 22.2 mm). We fitted a von Bertalanffy growth model to juvenile data using the following parameters: L infinity = 315 mm, K = 0.029 mo-1, and to = 0.5 mo. The model suggests that 27-28 mo are required (on average) before the outer lip begins to form. Two years after the enactment of Decree No. 159 in September 2004, which banned the Strombus fisheries in Panama for five years, the conch populations in Las Perlas and Coiba have not recovered. The Las Perlas population is recruitment limited and we recommend that a program of law enforcement and monitoring should be implemented immediately to protect this species, conducive to increase spawning and settlement in nursery grounds.

This study provides baseline data for the densities and biometrics of P. gracilis in Las Perlas and Coiba Archipelagos. The number of surveyed lobsters in both archipelagos was surprisingly low (85 in Las Perlas and 67 in Coiba), and average densities were dismal (4.1 plus or minus 8.8 ind. ha-1 and 5.3 plus or minus 7.6 ind. ha-1, respectively). Saboga and San Jose Islands had the highest relative densities of P. gracilis in Las Perlas, whereas intermediate relative densities were found only on Coiba Island in the Coiba Archipelago. Lobster density was not associated with either substrate or depth. In Las Perlas, female carapace length (CL) was 40-95 mm and that of males was 25-100 mm; in Coiba, female CL was 45-124 mm and male CL was 45-121 mm. In Las Perlas, the smallest lobster with eggs had a CL = 65 mm and a tail length (TL) = 120 mm, whereas the smallest in Coiba had a CL = 60 mm and a TL = 81-115 mm. We recommend implementing: (1) the minimum capture CL as the average carapace length at which half of the lobster population from Coiba is adult (CL = 84 mm; TL = 112-155 mm); (2) a fishing season no longer than 6 mo; (3) management decisions involving local fishermen and native peoples; (4) marine reserves or no-take areas (NTA); and (5) long-term monitoring plans, as the best current options to insure the survival of P. gracilis in the region.

Here, we studied one of the most common leaf morphotypes of the Cerrejon flora (middle-late Paleocene, ca. 60-58 Ma), Guajira, Colombia, that contains one of the oldest records of neotropical rain forest floras. Fifty-seven leaf specimens were carefully examined with a focus on general morphology, venation patterns, and cuticular characteristics. The analysis allowed us to recognize four new species that were assigned to the fossil-leaf genus Menispermites on the basis of an ovate leaf shape with cordate to truncate bases, actinodromous primary venation, brochidodromous secondary venation, percurrent tertiary venation, regular polygonal reticulate fourth and fifth venation, well-developed polygonal areoles, entire margin, and the presence of a fimbrial vein. This set of characters suggests a possible affinity with the pantropical angiosperm family Menispermaceae. The predominantly climbing habit of this family suggests that the Cerrejon Paleocene tropical rain forest was already multistratified. These findings represent the earliest record for the family in northern South America.

Much research has focused on the biogeography of speciation in the Amazon Basin, which harbors the greatest diversity of terrestrial life. The leading hypotheses on allopatric diversification of Amazonian taxa are the Pleistocene refugia, marine incursion, and riverine barrier hypotheses. Recent advances in the fields of phylogeography and species-distribution modeling permit a modern re-evaluation of these hypotheses. Our approach combines comparative, molecular phylogeographic analyses using mitochondrial DNA sequence data with paleodistribution modeling of species ranges at the last glacial maximum (LGM) to test these hypotheses for three co-distributed species of leafcutter ants (Atta spp.). The cumulative results of all tests reject every prediction of the riverine barrier hypothesis, but are unable to reject several predictions of the Pleistocene refugia and marine incursion hypotheses. Coalescent dating analyses suggest that population structure formed recently (Pleistocene-Pliocene), but are unable to reject the possibility that Miocene events may be responsible for structuring populations in two of the three species examined. The available data therefore suggest that either marine incursions in the Miocene or climate changes during the Pleistocene--or both--have shaped the population structure of the three species examined. Our results also reconceptualize the traditional Pleistocene refugia hypothesis, and offer a novel framework for future research into the area.

Few freshwater species attain a large size (>500 g). The largest species regularly caught today in the lower freshwater sections of many Panamanian rivers are of marine origin. Freshwater fish species diversity and biomass decline rapidly with altitude particularly on the Pacific watershed. Historically, people living inland have compensated for this deficiency by consuming salted and dried marine fish. In four drainages in the Santa Maria Biogeographical Province that abut onto Parita Bay (central Pacific Panama), archaeologists have recovered well-preserved fish faunas dating from the Late Preceramic period (7000-5000 uncalibrated (super 14) C years BP) to Spanish contact in AD 1515-20. Freshwater fish are scarce at most of these sites because they are-or were-located near the coast. Two more inland sites have produced significant samples of freshwater fish bones: a rock-shelter (Aguadulce Shelter, 7000-2500 BP) and a village (Sitio Sierra, 1800-1500 BP). At the Aguadulce Shelter freshwater fish remains represent about 50% of the taxonomically diagnostic teleost bone samples (>1.5 mm mesh) and at Sitio Sierra, 23% (>3.2 mm mesh). Twelve genera from ten families, probably representing twelve species of primary and secondary freshwater fish, have been recorded. Pre-Columbian communities preferentially consumed tiger-fish (Hoplias microlepis), silver catfish (Rhamdia quelen) and driftwood catfish (Trachelyopterus amblops). Although these are predatory species that readily take hooks, archaeological evidence for hook-and-line fishing is lacking. Since people living in the study area use poison for fishing today (e.g. Dioscorea spp.) this method may have been used in pre-Columbian times. Archaeozoological data shed light on the timing of westward migrations of fish species hypothesized to have taken advantage of Pleistocene river anastomosis to cross watersheds during periods of lowered sea level. No archaeofaunas of Pleistocene age are available. However, the presence of the driftwood catfish in Late Preceramic layers at the Aguadulce Shelter indicate that this species had moved into the Santa Maria drainage of the Santa Maria Biogeographical Province (SMBP) by 7000-4500 BP. Another South American species, a gar characin (Ctenolucius beani), is present in Early Ceramic (4500-2500 BP) deposits at the Aguadulce Shelter and also Monagrillo (4500-3300 BP) in the Parita drainage of the same province.

AN - 69617627; 18828279 AB - The Panama Canal is near its vessel size and tonnage handling capacity, and Panamanians have decided to expand it. The expansion of the Canal may consider the historical long-lasting impacts on marine coastal habitats particularly on sensitive coral reefs. These potential impacts were discussed during the national referendum as were other equally important issues, such as its effects on forests, watersheds, and water supply. Coral growth rates provide a direct measure of coral fitness and past environmental conditions comparable to analyses of tree rings. We examined stable isotopes, metal geochemical tracers, and growth rates on a century-long (1880-1989) chronology based on 77 cores of the dominant reef-building coral Siderastrea siderea collected near the Caribbean entrance to the canal. Our results showed a gradual decline in coral growth unrelated to changes in sea surface temperature but linked to runoff and sedimentation to coastal areas resulting from the construction and operation of the Panama Canal.

The egg chorions have exclusively been found on N. haidingeri leaves, where they are attached to the outer surface of the abaxial cuticle; one specimen suggests that the eggs were arranged in circles. It is impossible at present to determine the affinities of the eggs; possible producers may be beetles, dragonflies, sawflies, or other allied basal Hymenoptera. Ovipositional damage occurs on N. angustior leaves in the form of lenticular egg impressions surrounded by a narrow, elevated margin. The impressions are visible on the ad- and abaxial cuticle, and coincide when both cuticles are superimposed, which indicates that the eggs producing these impressions were injected into the interior of the leaf. Producers of eggs that may have caused these damages are perhaps dragonflies or damselflies. The restricted occurrence of the two types of ovipositional activity suggests that some kind of host specificity existed, perhaps related to specific preferences in larval diet.

Palaeogeographical models have interpreted a typically fluvial environment for the lower Mirador Formation and marginal to marine environments for its upper layers. The potential of marine influence in the upper Mirador beds and the overlying lower Carbonera formation as a correlation tool, and the palaeogeographic distribution of the event have not yet been defined. In order to determine the palaeogeography of this probable incursion, 80 wells and four sections were analysed using palynological techniques. The presence of a marine influence in the sediments was determined by using a Salinity Index (SI) that describes the negative relationship between continental and marine palynomorphs. The marine influence has been recognized in two areas: the first, in the Putumayo basin, and the second, in the Eastern Cordillera and Central Llanos Foothills. In the Putumayo basin the Salinity Index pattern reveals a southern provenance of the marine incursion, flooding the Colombian territory in a South-North trend through the Ecuadorian coast. The marine influence of the Eastern Cordillera and the Central-Eastern Llanos Foothills is more difficult to explain. We propose a possible corridor through the proto-Lower Magdalena Valley that connected the Caribbean Sea and the Central Llanos Foothills. Palaeogeographic models for the late Eocene of north-western South America should consider this marine incursion and its geographical distribution.

The clay minerals include Al- and the more common Fe/Mg- phyllosilicates with interlayer H (sub 2) O such as nontronite and saponite; some spectra from Nili Fossae shows spectra indicating high-Fe chlorite, while others from Mawrth Vallis have absorption spectra indicating montmorillonite. K/Al phyllosilicates-illite and/or muscovite are also identified in ejecta from a crater W of Nili Fossae. From rarer small outcrops kaolinite is identified and recorded previously. Olivine -rich rocks overlying clay-mineral accumulations indicate prior cessation of aqueous alteration. Many phyllosilicates occur in rims, ejecta and peaks of craters in the Southern Highlands and in sedimentary deposits. The absorption spectral evidence for the identification of all these minerals is detailed, with CRISM and laboratory reflectance spectra of the clay minerals. A new class of hydrated silicate is also identified characterized by a 2.20 to 2.25 mu m absorption distinct from that observed with Al-OH phyllosilicates such as montmorillonite. Most phyllosilicate spectra are consistent with the smectites montmorillonite, nontronite and saponite which require significant water reservoirs and moderate to alkaline pH conditions for their formation. The restriction of kaolinite to rare deposits argues against a widespread, vigorous hydrological system in the Noachian, or the possibility that the duration of such a system was sufficient for the formation of smectites but not kaolinite. But the localities with kaolinite, chlorite and hydrated SiO (sub 2) indicate that micro-environments with liquid water or hydrothermal activity occurred in early Mars.

In particular, we seek to evaluate the possibility that the current activity will culminate in major explosive Plinian-style event similar to that in 1913. Lava samples continue to show relatively heterogeneous whole-rock compositions with some significant mafic spikes (1999, 2001) as have prevailed since 1976. Groundmass SiO (sub 2) contents continue trends to lower levels that have prevailed since 1961, in the direction of the still lower groundmass SiO (sub 2) contents found in 1913 scoriae. Importantly, ash samples from investigated Vulcanian-style explosive eruptions in 2005 are devoid of particles with micro-vesiculated groundmass textures; such textures characterized the 1913 scoriae, signifying expansion of in-situ magmatic gas as the propellant of the 1913 eruption. All magmas erupted since 1913 appear to have arrived in the upper volcanic conduit system in a degassed state. The small to moderate Vulcanian-style explosive eruptions, which have been common since 1999 (>16,000 events), have blasted ash clouds as high as 11 km a.s.l. and sent pyroclastic flows out to distances of 5 km. These eruptions do not appear to be powered by expansion of in-situ magmatic gas. New small lava domes have been observed in the crater prior to many explosive eruptions. These plugs of degassed lava may temporarily seal the conduit and allow the build-up of magmatic gases streaming upward from below ahead of rising and degassing magma. In this interpretation, when gas pressure exceeds the strength of the plug seal in the upper conduit, an explosive Vulcanian-style eruption occurs. Alternatively these explosive eruptions may represent interactions of hot rock and groundwater (phreato-magmatic).

Magnetostratigraphic results indicate nine reverse magnetozones (R1 to R9) and eight normal magnetozones (N1 to N8) in the sedimentary profile, which can be correlated to the geomagnetic polarity timescale from C3n.3r to C1r.1r. The age of the sedimentary sequence of the Yuanmou Basin can thus be paleomagnetically constrained to an interval from early Pliocene to Pleistocene, with sedimentation rates varying from 12.5 to 55 cm/kyr. In addition to its highly resolved magnetostratigraphic sequence, the Yuanmou Basin provides a record of Plio-Pleistocene tectono- and climato-sedimentary processes. The mean declinations of the seventeen polarity units (excluding samples with transitional directions) can be grouped into three distinct directional intervals, Group I (2.58-1.37 Ma), Group II (4.29-2.58 Ma) and Group III (4.91-4.29 Ma). These directions indicate that the Yuanmou Basin has probably experienced vertical-axis clockwise rotation of about 12 degrees from 1.4 Ma to 4.9 Ma, which may be related to slip activity of the Red River fault to the southwest and the Xianshuihe-Xiaojiang fault to the east.

The morphology and spatial distribution of basin materials themselves closely match lunar counterparts. Evidence for a volcanic origin of the basin's interior plains includes embayed craters on the basin floor and diffuse deposits surrounding rimless depressions interpreted to be of pyroclastic origin. Unlike lunar maria, the volcanic plains in Caloris are higher in albedo than surrounding basin materials and lack spectral evidence for ferrous iron-bearing silicates. Tectonic landforms, contractional wrinkle ridges and extensional troughs, have distributions and age relations different from their counterparts in and around lunar basins, indicating a different stress history.

This pattern can be replicated with a new data set of fossil occurrences representing 3.5 million specimens, but only when older analytical protocols are used. Moreover, analyses that employ sampling standardization and more robust counting methods show a modest rise in diversity with no clear trend after the mid-Cretaceous. Globally, locally, and at both high and low latitudes, diversity was less than twice as high in the Neogene as in the mid-Paleozoic. The ratio of global to local richness has changed little, and a latitudinal diversity gradient was present in the early Paleozoic.

High-resolution images (down to 150 meters per pixel) obtained during the first MESSENGER flyby show evidence for volcanic vents around the Caloris basin inner margin and demonstrate that plains were emplaced sequentially inside and adjacent to numerous large impact craters, to thicknesses in excess of several kilometers. Radial graben and a floor-fractured crater may indicate intrusive activity. These observations, coupled with additional evidence from color images and impact crater size-frequency distributions, support a volcanic origin for several regions of plains and substantiate the important role of volcanism in the geological history of Mercury.

The encounter revealed that Mercury is a dynamic system; its liquid iron-rich outer core is coupled through a dominantly dipolar magnetic field to the surface, exosphere, and magnetosphere, all of which interact with the solar wind. MESSENGER images confirm that lobate scarps are the dominant tectonic landform and record global contraction associated with cooling of the planet. The history of contraction can be related to the history of volcanism and cratering, and the total contractional strain is at least one-third greater than inferred from Mariner 10 images. On the basis of measurements of thermal neutrons made during the flyby, the average abundance of iron in Mercury's surface material is less than 6% by weight.

A higher-reflectance, relatively red material occurs as a distinct class of smooth plains that were likely emplaced volcanically; a lower-reflectance material with a lesser spectral slope may represent a distinct crustal component enriched in opaque minerals, possibly more common at depth. A spectrally intermediate terrain probably forms most of the upper crust. Three other spectrally distinct but spatially restricted units include fresh crater ejecta less affected by space weathering than other surface materials; high-reflectance deposits seen in some crater floors; and moderately high-reflectance, relatively reddish material associated with rimless depressions.

Coffee agroecosystems with complex shade canopies protect biodiversity. Yet, few have examined biodiversity in coffee agroecosystems in Asia relative to the Americas and many question whether coffee agroecosystems can play a similar role for conservation. We examined vegetation, ant and bird diversity, coffee yields and revenues, and harvest of alternative products in coffee farms and forests in SW Sumatra, Indonesia near Bukit Barisan Selatan National Park (BBS). BBS is among the last habitats for large mammals in Sumatra and >15,000 families illegally cultivate coffee inside of BBS. As a basis for informing management recommendations, we compared the conservation potential and economic outputs from farms inside and outside of BBS. Forests had higher canopy cover, canopy depth, tree height, epiphyte loads, and more emergent trees than coffee farms. Coffee farms inside BBS had more epiphytes and trees and fewer coffee plants than farms outside BBS. Tree, ant, and bird richness was significantly greater in forests than in coffee farms, and richness did not differ in coffee farms inside and outside of BBS. Species similarity of forest and coffee trees, ants, and birds was generally low (<50%). Surprisingly, farms inside the park were significantly older, but farm size, coffee yields, and revenues from coffee did not depend on farm location. Farmers outside BBS received higher prices for their coffee and also more often produced other crops in their coffee fields such that incentives could be created to draw illegal farmers out of the park. We also discuss these results with reference to similar work in Chiapas, Mexico to compare the relative contribution of coffee fields to conservation in the two continents, and discuss implications for working with farmers in Sumatra towards conservation plans incorporating sustainable coffee production.

Seed dispersal mode did not explain significant variation in seed dispersal distances, but did explain significant variation in clumping: animal-dispersed species showed higher clumping of seed deposition.Among nine wind-dispersed species, the combination of diaspore terminal velocity, tree height and wind speed in the season of peak dispersal explained 40% of variation in dispersal distances. Among 31 animal-dispersed species, 20% of interspecific variation in dispersal distances was explained by seed mass (a negative effect) and tree height (a positive effect).Among all species, seed mass, tree height and dispersal syndrome explained 28% of the variation in mean dispersal distance and seed mass alone explained 45% of the variation in estimated seed production per basal area.Synthesis. There is wide variation in patterns of primary seed rain among tropical tree species. Substantial proportions of interspecific variation in seed production, seed dispersal distances, and clumping of seed deposition are explained by relatively easily measured plant traits, especially dispersal mode, seed mass, and tree height. This provides hope for trait-based generalization and modelling of seed dispersal in tropical forests.

Despite this, the ecological significance of organic phosphorus remains poorly understood, which is remarkable given the biological importance of phosphorus in terrestrial environments.Of particular interest is the possibility that coexisting plant species partition soil organic phosphorus to reduce competition. This seems likely given the large number of biologically available phosphorus compounds that occur in soil and the variety of mechanisms by which plants can utilize them.Here I propose a conceptual model of resource partitioning for soil phosphorus. The model describes a hypothetical example of four coexisting plant species that differ in their ability to access soil organic phosphorus compounds, which are grouped to form a gradient of biological availability based on the processes involved in their utilization by plants.Synthesis: Resource partitioning for soil phosphorus could provide an additional mechanism to explain the coexistence and distribution of plant species. It is likely to occur widely in terrestrial environments, but should have greatest ecological significance wherever productivity is limited by the availability of soil phosphorus. This includes freshwater wetlands, super-humid temperate regions and ecosystems developed on strongly-weathered soils that cover vast areas of ancient landscapes in Africa, Australia and South America.

Empirical studies of fragmented landscapes often reveal strong effects of fragment area and isolation on species richness, although other predictions of the theory, such as accelerated species turnover in fragments, have been tested less frequently. As predicted by IBT, biota in fragments typically 'relax' over time towards lower species richness. Beyond these broad generalizations, however, the relevance of IBT for understanding fragmented ecosystems is limited. First, IBT provides few predictions about how community composition in fragments should change over time, and which species should be most vulnerable. Second, edge effects can be an important driver of local species extinctions and ecosystem change, but are not considered by IBT. Third, the matrix of modified vegetation surrounding fragments-also ignored by IBT-can strongly influence fragment connectivity, which in turn affects the demography, genetics, and survival of local populations. Fourth, most fragmented landscapes are also altered by other anthropogenic changes, such as hunting, logging, fires, and pollution, which can interact synergistically with habitat fragmentation. Finally, fragmentation often has diverse impacts on ecosystem properties such as canopy-gap dynamics, carbon storage, and the trophic structure of communities that are not considered by IBT. I highlight these phenomena with findings from fragmented ecosystems around the world.

This paper provides zooarchaeological and taphonomic analyses and behavioral interpretations of three arrow right .5 million-year-old archaeofaunas from areas 1A and 103 in the Okote Member of the Koobi Fora Formation, northern Kenya: FwJj14A, FwJj14B, and GaJi14. These sites are all located in similar paleoenvironmental contexts, near shallow water with swampy, seasonally flooded areas, and some evidence for more wooded or gallery forest settings. Both individual specimen- and assemblage-level analyses of butchery-marked bones indicate that the hominins appear to have practiced similar butchery strategies at all of these sites, with butchery (defleshing, disarticulation, and marrow extraction) of both high- and low-ranked skeletal elements with no apparent preference for prey size, skeletal region, limb class, or limb portion. Only four tooth-marked specimens, including one likely crocodile-tooth-marked bone, are preserved in all three archaeofaunas. A paucity of limb epiphyses suggests that bone-crunching hyenids may have deleted these portions subsequent to hominin butchery. Strangely, there are no stone tools preserved with the 292 cut-marked and 27 percussion-marked faunal specimens (out of a total of 6,039 specimens), suggesting that raw material availability may have conditioned hominin lithic discard patterns at these locales. These assemblages increase our knowledge of the dietary behavior and ecology of Homo erectus, and provide support for variability in early Pleistocene hominin carcass foraging patterns.

Sexual (aclonal) colonies are derived from larvae while asexual (clonal) colonies result from the fragmentation or division of larger colonies. A number of specialised morphologies exist which either enhance or discourage clonality, and cupuladriids preserve these in their skeletons, meaning that it is possible to count the abundances of individual modes of reproduction in fossil assemblages, and thus measure the mode and tempo of evolution of life histories using fossil colonies. In this paper we categorise, illustrate and describe the various clonal and aclonal methods of propagation in cupuladriids through the Cenozoic. Sexual reproduction is the only aclonal method of propagation, while four clonal methods are described comprising: (1) mechanical fragmentation, (2) autofragmentation, (3) colonial budding and (4) peripheral fragmentation. The processes involved in each are discussed and we explain how their prevalence can be measured in the fossil record using preservable morphologies. Compiling a record of the occurrence and distribution of the various modes of propagation through time and space we discover a general trend of evolution towards more complex modes in all three cupuladriid genera, but a geologically recent extinction of some modes of propagation that has left the present-day assemblage relatively depauperate. We see striking similarities in the general timing of expansion of modes of reproduction between the two most important genera, Cupuladria and Discoporella, although it is clear that Discoporella evolved a much wider range of special morphologies either to enhance or to discourage clonality than did Cupuladria.

The effects of upwelling on gelatinous zooplankton are largely unknown and undocumented for this or any region, although upwelling is known to shape phytoplankton dynamics. Small hydromedusae, the most widespread and diverse representatives of gelatinous plankton, are often neglected in plankton ecology as they are inconspicuous and escape direct observation. Their occurrence is seasonal and standard plankton sampling techniques easily overlook their blooms. In order to investigate whether upwelling affects hydromedusae dynamics, we monitored their abundance and diversity in the Bay of Panama, a region on the Pacific Coast of Panama characterized by seasonal upwelling events. Our results show that, although the number of species is relatively constant throughout the year, hydromedusa abundance in the Bay of Panama can be up to two orders of magnitude higher during upwelling than non-upwelling conditions. The difference in the numbers of hydromedusae between the two seasons is mostly due to temporally short medusa blooms that occur only during the upwelling season. Our results point to a link between hydromedusa blooms and upwelling events, and the increased productivity associated with them. The results are consistent with a scenario in which upwelling events act on the benthic colonies thus inducing medusa production.

Of tested endophytic morphospecies, 40% (21/52), 65% (28/43) and 27% percent (4/15) showed in vitro antagonism against Moniliophthora roreri (frosty pod rot), Phytophthora palmivora (black pod rot) and Moniliophthora perniciosa (witches broom), respectively. The most common antagonistic mechanism was simple competition for substrate. Nonetheless, 13%, 21%, and 0% of tested morphospecies showed clear antibiosis against M. roreri, P. palmivora, and M. perniciosa, respectively. One isolate of Trichoderma was observed to be parasitic on M. roreri. Endophyte species that were common in the host plants under natural conditions often are good colonizers and grow fast in vitro whereas antibiosis producers usually appear to be relatively rare in nature, tend to grow slowly in vitro, and often are not good colonizers. We suggest that there is an inherent general trade-off between fast growth (high colonization) and production of chemicals that produce antibiosis reactions. Finally, field trials assessing the effects of three endophytic fungi (Colletotrichum gloeosporioides, Clonostachys rosea and Botryosphaeria ribis) on pod loss due to M. roreri and Phytophthora spp. were conducted at four farms in Panama. Although the overall incidence of black pod rot was very low during the tests, treatment with C. gloeosporioides significantly decreased pod loss due to that disease. We observed no decrease in pod loss due to frosty pod rot, but treatment with C. rosea reduced the incidence of cacao pods with sporulating lesions of M. roreri by 10%. The observed reduction in pod loss due to Phytophthora spp., and sporulation by M. roreri, supports the potential of fungal endophytes as biological control agents. Further, these studies suggest that combined information from field censuses of endophytic fungi, in vitro studies, and greenhouse experiments can provide useful a priori criteria for identifying desirable attributes for potential biocontrol agents.

From September through December 2006, 821 samples from birdstrike events occurring in the United States were submitted for DNA analysis. We successfully amplified a CO1 DNA barcode product from 554 (67.5%) of the samples; 267 (32.5%) did not contain viable DNA and depended on morphological methods (microscopy) for Order or Family level identification. We deemed 19 cases inconclusive either because the DNA barcode recovered from the sample did not meet our 98% match criteria when compared to the Barcode of Life Database (BoLD) or because the DNA barcode matched to a set of .2 closely related species with overlapping barcodes, preventing complete species identification. Age of the sample (,6 months) did not affect DNA viability, but initial condition of the sample and the collection method was critical to DNA identification success. The DNA barcoding approach has great potential in aiding in identification of birds (and wildlife) for airfield management practices, particularly in regions of the world that lack the vast research collections and individual expertise for morphologic identifications.

Genetic techniques for matching dispersed seeds to maternal trees provide valuable data on dispersal events. Questions remain regarding how best to estimate the population seed dispersal distance distributions from such data and how these estimates compare with classical non-genetic estimates based on seed trap data alone.Using simulated data, we compared seed shadow estimates obtained via standard inverse modelling of seed arrival into seed traps within mapped stands (summed seed shadow, SSS) with estimates from four models using genetic matches: direct fitting of the observed distribution of distances in the genotyped sample (observed distance, OBS), direct fitting inversely weighted by sampling intensity (OBSw), inverse modelling of numbers of seeds of each genotype in each trap (gene shadow model, GSM), and inverse modelling of frequencies of each genotype in each trap (competing sources model, CSM). We further explored how consideration of immigrant seed rain from unmapped and ungenotyped trees outside the stand affected dispersal estimates, denoting these variants SSSi, GSMi and CSMi.We applied these models to an empirical data set for the Neotropical tree Jacaranda copaia, using a hierarchical Bayesian model to incorporate variation in fecundity among trees.Fits to simulated data sets showed that OBS and SSS estimates were strongly biased, while SSSi, GSMi and CSMi were mildly biased. Root mean square errors varied as OBS>>SSS>OBSw >CSMi>GSMi>SSSi>&nb sp; CSM>GSM.Comparing results for Jacaranda under the three best models, mean posterior estimates of dispersal distances varied as SSSiSynthesis. Here we reconcile two general approaches used to study seed dispersal distances in natural communities. Genetic and non-genetic approaches can both provide good estimates of seed dispersal provided that analyses of genetic data take account of any deviation from random selection of seeds for genotyping, and that SSS models consider immigrant seed rain in the analysis whenever there is reason to think its contribution is non-zero. The use of the models presented here should provide better estimates of population-level dispersal distance distributions in genetic and classical seed dispersal studies.

The present special issue presents a radically different situation: a highly contentious debate confronts not only marine turtle conservationists, but exposes the tip of an iceberg bearing much wider and deeper conundrums menacing coastal ecology and human communities, local conservationists and their organizations, and the conservation industry writ large - not to mention prickly questions of governance and human values: dignity, ethics, and integrity.

The larvae of this bagworm are unusual in being obligatory predators, feeding on a broad range of living arthropods, including Arachnida, Coleoptera, Homoptera, Hymenoptera, Neuroptera, and Orthoptera. Probably because of their relative abundance, ants seem to be the most frequent prey. The eggs of this species are protected in a manner that may be unique for insects. Soon after an egg exits the female ovipore, it is wrapped inside a small cocoon-like case constructed of specialized setae from the seventh abdominal segment. Hypotheses as to how these eggs are wrapped and how the cases may protect the eggs are proposed.

Differential use of the aerosphere is an important factor structuring bat assemblages, with species exhibiting distinct morphological, physiological, and sensory adaptations to different habitat types. This necessitates comprehensive sampling methodologies such as combined ground-level and canopy-level mist netting as well as acoustic monitoring to assess the presence, diversity, and activity of different functional groups of species adequately. Recent technological advances in acoustic detection and in methods of analysis, coupled with the expansion of libraries of echolocation calls for species identification, now allow for the reliable quantification of species numbers and activity of the scarcely known group of aerial insectivorous bats, particularly in species-rich tropical assemblages. We provide a brief, exemplary overview of recent studies on bats conducted in Panama to demonstrate the necessity of comprehensive sampling methods and application of new technologies in order to adequately depict assemblage composition and responses of bats to structural changes in habitats induced by fragmentation. In addition to acoustic methods, miniaturization of radio transmitters has provided new insights into the patterns of spatial use of the aerosphere by bats and has identified species-specific differences in mobility as one of the important traits that determines bats' reactions to anthropogenic alterations of the landscape. Following the goals of the symposium on aeroecology, we propose new avenues of research for probing the aerosphere. We discuss how integration of a diverse array of remote sensing tools with data on species distribution and species traits, such as mobility and edge-sensitivity, might provide novel opportunities for the development, and application of conservation-oriented monitoring systems.

multiple origins of shallow-water corals from deep-sea ancestors AN - 821965688; 2011-007424 AB - Shallow-water tropical reefs and the deep sea represent the two most diverse marine environments. Understanding the origin and diversification of this biodiversity is a major quest in ecology and evolution. The most prominent and well-supported explanation, articulated since the first explorations of the deep sea, holds that benthic marine fauna originated in shallow, onshore environments, and diversified into deeper waters. In contrast, evidence that groups of marine organisms originated in the deep sea is limited, and the possibility that deep-water taxa have contributed to the formation of shallow-water communities remains untested with phylogenetic methods. Here we show that stylasterid corals (Cnidaria: Hydrozoa: Stylasteridae)--the second most diverse group of hard corals--originated and diversified extensively in the deep sea, and subsequently invaded shallow waters. Our phylogenetic results show that deep-water stylasterid corals have invaded the shallow-water tropics three times, with one additional invasion of the shallow-water temperate zone. Our results also show that anti-predatory innovations arose in the deep sea, but were not involved in the shallow-water invasions. These findings are the first robust evidence that an important group of tropical shallow-water marine animals evolved from deep-water ancestors.

[Part 5 of 5] T2 - SMITHSONIAN INSTITUTION NATIONAL MUSEUM OF AFRICAN-AMERICAN HISTORY AND CULTURE, BETWEEN 14TH AND 15TH STREETS AND CONSTITUTION AVENUE AND MADISON DRIVE IN NORTHWEST WASHINGTON, DISTRICT OF COLUMBIA. AN - 36399312; 13485-080247_0005 AB - PURPOSE: The construction and operation of the National Museum of African-American History and Culture between 14th and 15th streets and Constitution Avenue and Madison Drive in Northwest Washington, District of Columbia are proposed by the Smithsonian Institution. The project would provide and operate a permanent facility on the Washington Monument Grounds within the Smithsonian Institution on a five-acre parcel. Issues addressed in selecting the site and the building design include those related to massing (the form of a building conveying proportion and size), building height, setback and alignment, outdoor program space, and the viewshed. In addition the Smithsonian Institution developed eight overarching principles that provided a foundation for the development of alternatives, guided their refinement, and served as criteria for success; these principles are related to physical character, mission and program appropriateness, monumental context, urban design principles associated with physical context, historic and cultural resource protection, visitor use and access, visitor experience, and operational functionality. This final EIS considers seven alternatives, including a No-Build Alternative. Depending on the action alternative considered, the building would rise 60 to 105 feet above street level, providing for five to eight floors above grade and two to three floors below grade. The facility would contain 350,000 to 430,000 square feet. The north-south building orientation would align with the National Museum of American History's (NMAH) main building mass under three alternatives, the NMAH's north facade building mass under one alternative; and with no surrounding building under two alternatives. The east-west building orientation would align with the protecting portico of the Department of Commerce, the southwest facade of the Washington Monument, or 14th Street, or would be unaligned with respect to east-west orientation. Aesthetically, Alternative 1 would result in contextual massing the explicitly related to the pattern of buildings fronting the National Mall. Alternative 2 would be less convention in form and bridge the axis of the Mall with the north-south axis of open spaces leading to the White House. Alternative 3 would provide a more complex design, with the potential for buildings that look very different from a variety of locations. Alternative 4 would provide two distinct aesthetic experiences, blending into the landscape towards the Monument, while exhibiting more traditional building facades at the intersection of Constitution Avenue and 14th Street. Alternative 5 would provide for a bifurcated structure with varying heights, relating to context through building and spatial orientation rather than building or height alignment. Alternative 6 would offer a minimized visible mass and a soft edge along the southwest facade that would be aligned with 15th Street and Madison Drive, deferring to the presence of the Washington Monument. POSITIVE IMPACTS: The museum would be dedicated to the collection, preservation, research, and exhibition of American historical and cultural materials, reflecting the breadth and depth of the experience of individuals of African descent living in the United States. It would constitute the only institution providing a national meeting place for Americans to learn about the history and culture of African-Americans and their contributions to and relationship with every aspect of our national life. Increased visitation to the District of Columbia due to the attraction of the museum would boost the local economy. NEGATIVE IMPACTS: The museum would displace an open space on the Washington Monument grounds of the National Mall, altering the historic boundaries of the grounds and altering the spatial organization of the grounds by diminishing the prominence of the Washington Monument as a central organizing feature. Significant impacts would also occur for buildings and structures located within the Monument grounds as well as the Federal Triangle along Constitution Avenue. Vegetation and alternative land uses would be removed. The viewshed and specific vistas would be altered. The museum would be situated in an area in violation of federal standards regarding ozone and particulate matter.

AN - 36383062; 13485-080247_0003 AB - PURPOSE: The construction and operation of the National Museum of African-American History and Culture between 14th and 15th streets and Constitution Avenue and Madison Drive in Northwest Washington, District of Columbia are proposed by the Smithsonian Institution. The project would provide and operate a permanent facility on the Washington Monument Grounds within the Smithsonian Institution on a five-acre parcel. Issues addressed in selecting the site and the building design include those related to massing (the form of a building conveying proportion and size), building height, setback and alignment, outdoor program space, and the viewshed. In addition the Smithsonian Institution developed eight overarching principles that provided a foundation for the development of alternatives, guided their refinement, and served as criteria for success; these principles are related to physical character, mission and program appropriateness, monumental context, urban design principles associated with physical context, historic and cultural resource protection, visitor use and access, visitor experience, and operational functionality. This final EIS considers seven alternatives, including a No-Build Alternative. Depending on the action alternative considered, the building would rise 60 to 105 feet above street level, providing for five to eight floors above grade and two to three floors below grade. The facility would contain 350,000 to 430,000 square feet. The north-south building orientation would align with the National Museum of American History's (NMAH) main building mass under three alternatives, the NMAH's north facade building mass under one alternative; and with no surrounding building under two alternatives. The east-west building orientation would align with the protecting portico of the Department of Commerce, the southwest facade of the Washington Monument, or 14th Street, or would be unaligned with respect to east-west orientation. Aesthetically, Alternative 1 would result in contextual massing the explicitly related to the pattern of buildings fronting the National Mall. Alternative 2 would be less convention in form and bridge the axis of the Mall with the north-south axis of open spaces leading to the White House. Alternative 3 would provide a more complex design, with the potential for buildings that look very different from a variety of locations. Alternative 4 would provide two distinct aesthetic experiences, blending into the landscape towards the Monument, while exhibiting more traditional building facades at the intersection of Constitution Avenue and 14th Street. Alternative 5 would provide for a bifurcated structure with varying heights, relating to context through building and spatial orientation rather than building or height alignment. Alternative 6 would offer a minimized visible mass and a soft edge along the southwest facade that would be aligned with 15th Street and Madison Drive, deferring to the presence of the Washington Monument. POSITIVE IMPACTS: The museum would be dedicated to the collection, preservation, research, and exhibition of American historical and cultural materials, reflecting the breadth and depth of the experience of individuals of African descent living in the United States. It would constitute the only institution providing a national meeting place for Americans to learn about the history and culture of African-Americans and their contributions to and relationship with every aspect of our national life. Increased visitation to the District of Columbia due to the attraction of the museum would boost the local economy. NEGATIVE IMPACTS: The museum would displace an open space on the Washington Monument grounds of the National Mall, altering the historic boundaries of the grounds and altering the spatial organization of the grounds by diminishing the prominence of the Washington Monument as a central organizing feature. Significant impacts would also occur for buildings and structures located within the Monument grounds as well as the Federal Triangle along Constitution Avenue. Vegetation and alternative land uses would be removed. The viewshed and specific vistas would be altered. The museum would be situated in an area in violation of federal standards regarding ozone and particulate matter.

This paper focuses on the possibilities of and challenges to sustainable certification efforts with particular focus on biodiversity conservation concerns. It presents the potential contributions from scientists in the certification processes, particularly to ensure that concern actually translates into measurable progress toward conservation goals. The benefits of unifying the three main certifications (organic, Fair Trade, and eco-friendly or shade grown), or triple-certified coffee, are explored. In general, benefits for biodiversity conservation and social justice from sustainable coffee certification can only be enhanced by greater cooperation among the current market-based efforts and scientists researching this unique response to globalization.

However, study of these effects is difficult. The conventional high-field magnets used for most hyperpolarized super(3)He magnetic resonance imaging (MRI) of the human lung, and most other common radiologic imaging modalities including positron emission tomography and computed tomography, restrict subjects to lying horizontally, minimizing most gravitational effects. Materials and Methods - In this article, we review the motivation for posture-dependent studies of human lung function and present initial imaging results of human lungs in the supine and vertical body orientations using inhaled hyperpolarized super(3)He gas and an open-access MRI instrument. The open geometry of this MRI system features a "walk-in" capability that permits subjects to be imaged in vertical and horizontal positions and potentially allows for complete rotation of the orientation of the imaging subject in a two-dimensional plane. Results - Initial results include two-dimensional lung images acquired with [not, vert, similar]4 x 8 mm in-plane resolution and three-dimensional images with [not, vert, similar]2-cm slice thickness. Conclusions - Effects of posture variation are observed, including posture-related effects of the diaphragm and distension of the lungs while vertical.

Anecdotal reports have suggested that adults of certain riverine tiger beetle species may be active during the dry season near perennial water sources. To test this hypothesis, fifteen sites along three perennial rivers in Kruger National Park, South Africa, were surveyed for tiger beetles in early September, 2006. Thirteen sites yielded adult beetles, with six species represented [Chaetodera regalis (Dejean), Cylindera disjuncta (Dejean), Habrodera nilotica (Dejean), Lophyra neglecta intermediola (Horn), Lophyridia fimbriata imperatrix (Srnka), and Myriochile melancholica (Fabricius)]. Microhabitat associations of adults of all six species and ovipositional-larval substrates of five of the six species are reported, along with observations on predatory and reproductive behaviours and the possible presence of an anti-predator chemical defence in C. regalis and L. fimbriata imperatrix.

Some of these activities modify the selective regime of the builder (niche construction) and some influence the ecological success of other species (ecosystem engineering) as well as their evolutionary prospects. In this article, I argue that these processes produce effects that persist over geological time, modulating macroevolutionary patterns and diversity. Examples include greater sediment bioturbation and increased thickness and persistence of shell beds. The impact of these processes has been increasing over time, with recent communities encompassing greater ecosystem engineering than those of the early Phanaerozoic. Thus, positive feedback through environmentally mediated selection seems to have increasingly enhanced biodiversity through the Phanaerozoic.

Damage from intense winds may be especially severe in fragmented forests because of their abrupt artificial margins and denuded surrounding landscapes. We review available information on the effects of windstorms on fragmented forests, synthesizing studies from Australasia, Amazonia and elsewhere in the tropics. Wind damage in fragmented landscapes can be influenced by a range of factors, such as forest-edge orientation, edge structure, the size of nearby clearings and local topography. We argue that wind disturbances are likely to interact with, and exacerbate, a range of deleterious environmental changes in fragmented forests. Among the most important of these are altered forest structure, shifts in plant species composition, exotic-plant invasions, reduced carbon storage and elevated vulnerability to fire. The damaging impacts of winds on fragmented forests could potentially increase in the future, particularly if global warming leads to increasingly severe or frequent windstorms.

The branching pattern and combination of asymmetric blunt spindles, abundance of capstans, and a low occurrence of acute spindles are distinct characteristics of the new taxon. The new species is described, illustrated and compared to the other species of the genus reported from Pacific Panama; thus increasing the total of Leptogorgia species to 17, which encompasses over 70% of the shallow water species for the eastern Pacific.

In the rainforests of southern Gabon, we used spotlighting surveys to estimate abundances of nocturnal mammal species and guilds at varying distances from forest roads and between hunted and unhunted treatments (comparing a 130-km2 oil concession that was nearly free of hunting, with nearby areas outside the concession that had moderate hunting pressure). At each of 12 study sites that were evenly divided between hunted and unhunted areas, we established standardized 1-km transects along road verges and at 50, 300, and 600 m from the road. We then repeatedly surveyed mammals at each site during 2006. Hunting had few apparent effects on this assemblage. Nevertheless, the species richness and often the abundance of nocturnal primates, smaller ungulates, and carnivores were significantly depressed within approximately 30 m of roads. Scansorial rodents increased in abundance in hunted forests, possibly in response to habitat changes caused by logging or nearby swidden farming. In multiple-regression models many species and guilds were significantly influenced by forest-canopy and understory cover, both of which are altered by logging and by certain abiotic variables. In general, nocturnal species, many of which are arboreal or relatively small in size (<10 kg), were less strongly influenced by hunting and more strongly affected by human-induced changes in forest structure than were larger mammal species in our study area.

Both genetic and environmental factors have been proposed as possible causes of this problem. We investigated the possibility that population genetic processes (isolation, inbreeding and genetic drift) have contributed to an increased frequency of cryptorchidism in this population. Overall, SBTD on major islands throughout Alaska have unusually low levels of genetic diversity, though we identified a likely glacial refugium on Prince of Wales Island in the Alexander Archipelago. Within the Kodiak Archipelago, deer on the AP did not exhibit the patterns of genetic isolation, inbreeding and drift that would be expected if cryptorchidism in this population was the result of a founder mutation(s). Instead, our data favor exposure to environmental contaminants as a likely alternative mechanism causing high prevalence of cryptorchidism on the AP.

Myanmar has the largest captive population worldwide ( similar to 6000), maintained at this level for over a century. We used published demographic data to assess the viability of this captive population. We tested how this population can be self-sustained, how many elephants must be supplemented from the wild to maintain it, and what consequences live capture may have for Myanmar's wild population. Our results demonstrate that the current captive population is not self-sustaining because mortality is too high and birth rates are too low. Our models also suggest similar to 100elephantsyear-1 have been captured in the wild to supplement the captive population. Such supplementation cannot be supported by a wild population of fewer than 4000 elephants. Given the most recent expert estimate of similar to 2000 wild elephants remaining in Myanmar, a harvest of 100elephantsyear-1 could result in extinction of the wild population in 31years. Continued live capture threatens the survival of wild and captive populations and must stop. In addition, captive breeding should be increased. These measures are essential to slow the decline and extinction of all of Myanmar's elephants.

However, although stream ecosystems are tightly coupled with their catchments and, thus, probably are affected strongly by historical catchment conditions, few studies have directly examined the importance of landuse legacies on streams. We examined relationships between historical land use (1944) and contemporary (2000-2003) stream physical, chemical, and biological conditions after accounting for the influences of contemporary land use (1999) and natural landscape (catchment size) variation in 12 small streams at Fort Benning, Georgia, USA. Most stream variables showed strong relationships with contemporary land use and catchment size; however, after accounting for these factors, residual variation in many variables remained significantly related to historical land use. Residual variation in benthic particulate organic matter, diatom density, % of diatoms in Eunotia spp., fish density in runs, and whole-stream gross primary productivity correlated negatively, whereas streamwater pH correlated positively, with residual variation in fraction of disturbed land in catchments in 1944 (i.e., bare ground and unpaved road cover). Residual variation in % recovering land (i.e., early successional vegetation) in 1944 was correlated positively with residual variation in streambed instability, a macroinvertebrate biotic index, and fish richness, but correlated negatively with residual variation in most benthic macroinvertebrate metrics examined (e.g., Chironomidae and total richness, Shannon diversity). In contrast, residual variation in whole-stream respiration rates was not explained by historical land use. Our results suggest that historical land use continues to influence important physical and chemical variables in these streams, and in turn, probably influences associated biota. Beyond providing insight into biotic interactions and their associations with environmental conditions, identification of landuse legacies also will improve understanding of stream impairment in contemporary minimally disturbed catchments, enabling more accurate assessment of reference conditions in studies of biotic integrity and restoration.

The MWA is sensitive to roughly a decade in scale (wavenumbers of [image] -1 h Mpc super(-1)). This amounts primarily to constraints on two numbers: the amplitude and the slope of the 21 cm power spectrum on the scales probed. We find, however, that the redshift evolution in these quantities can yield important information about reionization. We examine a range of theoretical models, spanning uncertainties in the nature of the ionizing sources and the abundance of minihalos during reionization. Although the power spectrum differs substantially among these models, a generic prediction is that the amplitude of the 21 cm power spectrum on MWA scales ([image] h Mpc super(-1)) peaks near the epoch when the intergalactic medium (IGM) is [sim]50% ionized. Moreover, the slope of the 21 cm power spectrum flattens as the ionization fraction increases and the sizes of the H ii regions grow. With regards to detection sensitivity, we show that the optimal MWA antenna configuration for power spectrum measurements would pack all 500 antenna tiles as closely as possible in a compact core. Detecting the characteristic redshift evolution of our models will help to confirm that observed 21 cm fluctuations originate from the IGM, and not from foregrounds, and will provide an indirect constraint on the evolution of the volume-filling factor of H ii regions during reionization.

Such structure is well-characterized for typical mammalian societies; that is, societies where social group composition is stable, dispersal is male-biased, and males form permanent breeding associations in just one or a few social groups over the course of their lives. However, genetic structure is not well understood for social mammals that differ from this pattern, including elephants. In elephant societies, social groups fission and fuse, and males never form permanent breeding associations with female groups. Here, we combine 33 years of behavioural observations with genetic information for 545 African elephants (Loxodonta africana), to investigate how mating and dispersal behaviours structure genetic variation between social groups and across age classes. We found that, like most social mammals, female matrilocality in elephants creates co-ancestry within core social groups and significant genetic differentiation between groups ( Phi ST = 0.058). However, unlike typical social mammals, male elephants do not bias reproduction towards a limited subset of social groups, and instead breed randomly across the population. As a result, reproductively dominant males mediate gene flow between core groups, which creates cohorts of similar-aged paternal relatives across the population. Because poaching tends to eliminate the oldest elephants from populations, illegal hunting and poaching are likely to erode fine-scale genetic structure. We discuss our results and their evolutionary and conservation genetic implications in the context of other social mammals.

13265848 AB - A water quality model was developed to track the fate and transport of four arsenic species in the Patuxent Estuary: arsenate (As(V)), arsenite (As(III)), methylarsonate (MMA), and dimethylarsinate (DMA). Processes simulated include mass transport, solid--liquid partitioning with suspended solids, uptake and transformation of As(V) by phytoplankton, oxidation of As(III), demethylation of MMA and DMA, and settling/deposition/resuspension of particulate arsenic in the water column. A sediment module was also developed and linked with the water column to generate fluxes of inorganic arsenic from the sediment bed. The arsenic model was calibrated using water quality data from the Patuxent Estuary over a period ranging from May 24, 1995 to October 29, 1997. Model results indicated that transformation of arsenic by phytoplankton is not a significant source of DMA to the lower Patuxent. Instead, results suggested that the primary source of methylated arsenic (DMA and MMA) to the lower estuary is beyond the downstream boundary (Chesapeake Bay). However, model results supported the hypothesis that flux of arsenic from the sediment is a significant source of inorganic arsenic to the lower estuary.

We can distinguish (1) a block-poor ejecta facies composing a concentric halo of mantling material 10 m or greater in thickness that extends more than 1000 km from the basin center, and (2) a melt-rich deposit that forms a discontinuous but areally extensive stratigraphic marker across the southern highlands. The melt-rich component likely extends well into the South Pole-Aitken basin, a key target for future landed and sample return missions. The observation of these two ejecta facies and their distribution across the southern nearside yields new insight into the types and distribution of material contributed by large basin-forming impacts to the highlands megaregolith.

Spinel is consistently the most (super 16) O-rich (Delta (super 17) O = -25 ppm to -15 ppm), followed by Al,Ti-dioside (Delta (super 17) O = -20 ppm to -5 ppm) and anorthite (Delta (super 17) O = -15 ppm to 0 ppm). Melilite is the most (super 16) O-depleted primary mineral (Delta (super 17) O = -5 ppm to -3 ppm). We conclude that the original melting event that formed Type C CAIs occurred in a (super 16) O-rich (Delta (super 17) O < or = -20 ppm) nebular gas and they subsequently experienced oxygen isotopic exchange in a (super 16) O-poor reservoir. At least three of these (ABC, TS26F1 and 93) experienced remelting at the time and place where chondrules were forming, trapping and partially assimilating (super 16) O-poor chondrule fragments. The observation that the pyroxene is (super 16) O-rich relative to the feldspar, even though the feldspar preceded it in the igneous crystallization sequence, disproves the class of CAI isotopic exchange models in which partial melting of a (super 16) O-rich solid in a (super 16) O-poor gas is followed by slow crystallization in that gas. For the typical (not associated with chondrule materials) Type C CAIs as well for as the Types A and B CAIs, the exchange that produced internal isotopic heterogeneity within each CAI must have occurred largely in the solid state. The secondary phases grossular, monticellite and forsterite commonly have similar oxygen isotopic compositions to the melilite and anorthite they replace, but in one case (CAI 160) grossular is (super 16) O-enriched (Delta (super 17) O = -10 ppm to -6 ppm) relative to melilite (Delta (super 17) O = -5 ppm to -3 ppm), meaning that the melilite and anorthite must have exchanged its oxygen subsequent to secondary alteration. This isotopic exchange in melilite and anorthite likely occurred on the CV parent asteroid, possibly during fluid-assisted thermal metamorphism.

W. and Lindstrom, M. M. (2001) Petrology and geochemistry of Patuxent Range 91501 and Lewis Cliff 88663. Meteoritics Planet. Sci. 36, 439-457]. We conducted mineralogical and tomographic studies of previously unstudied mm- to cm-sized metal-sulfide-vesicle assemblages and chronologic studies of the silicate host. Metal-sulfide clasts constitute about 1 vol.%, comprise zoned taenite, troilite, and pentlandite, and exhibit a consistent orientation between metal and sulfide and of metal-sulfide contacts. Vesicles make up nearly equal 2 vol.% and exhibit a similar orientation of long axes. (super 39) Ar- (super 40) Ar measurements probably date the time of impact at 4.461 + or - 0.008 Gyr B.P. Cosmogenic noble gases and (super 10) Be and (super 26) Al activities suggest a pre-atmospheric radius of 40-60 cm and a cosmic ray exposure age of 25-29 Myr, similar to ages of a cluster of L chondrites. PAT 91501 dates the oldest known impact on the L chondrite parent body. The dominant vesicle-forming gas was S (sub 2) ( nearly equal 15-20 ppm), which formed in equilibrium with impact-melted sulfides. The meteorite formed in an impact melt dike beneath a crater, as did other impact melted L chondrites, such as Chico. Cooling and solidification occurred over nearly equal 2 h. During this time, nearly equal 90% of metal and sulfide segregated from the local melt. Remaining metal and sulfide grains oriented themselves in the local gravitational field, a feature nearly unique among meteorites. Many of these metal-sulfide grains adhered to vesicles to form aggregates that may have been close to neutrally buoyant. These aggregates would have been carried upward with the residual melt, inhibiting further buoyancy-driven segregation. Although similar processes operated individually in other chondritic impact melts, their interaction produced the unique assemblage observed in PAT 91501.

Opaline silica deposits (as much as 91 weight percent SiO (sub 2) ) have been found in association with volcanic materials by the Mars rover Spirit. The deposits are present both as light-toned soils and as bedrock. We interpret these materials to have formed under hydrothermal conditions and therefore to be strong indicators of a former aqueous environment. This discovery is important for understanding the past habitability of Mars because hydrothermal environments on Earth support thriving microbial ecosystems.

Radar reflections within the deposits reveal a laterally continuous deposition of layers, which typically consist of four packets of finely spaced reflectors separated by homogeneous interpacket regions of nearly pure ice. The packet/interpacket structure can be explained by approximately million-year periodicities in Mars' obliquity or orbital eccentricity. The observed approximately 100-meter maximum deflection of the underlying substrate in response to the ice load implies that the present-day thickness of an equilibrium elastic lithosphere is greater than 300 kilometers. Alternatively, the response to the load may be in a transient state controlled by mantle viscosity. Both scenarios probably require that Mars has a subchondritic abundance of heat-producing elements.

However, almost one in five of the world's nearly 2300 rodent species is an island endemic, and insular rodents suffer from high rates of extinction and endangerment. Rates of Quaternary extinction and current threat are especially high in the West Indies and the species-rich archipelagos of Southeast Asia. Rodent endemism reaches its most striking levels on large or remote oceanic islands, such as Madagascar, the Caribbean, the Ryukyu Islands, the oceanic Philippines, Sulawesi, the Galapagos, and the Solomon Islands, as well as on very large land-bridge islands, especially New Guinea. While conservation efforts in the past and present have focused mainly on charismatic mammals (such as birds and large mammals), efforts specifically targeted toward less conspicuous animals (such as insular rodents) may be necessary to stem large numbers of extinctions in the near future.

NAPI is an index of phosphorus pollution potential. NAPI was estimated by quantifying all phosphorus inputs and outputs for each county. Inputs include fertilizer applications and non-food phosphorus uses, while trade of food and feed can be an input or an output. The average of 1987, 1992, 1997, and 2002 NAPI for individual counties ranged from 0.02 to 78.46kgPha super(-1)year super(-1). The overall area-weighted average NAPI for 266 counties in the region was 4.52kgPha super(-1[) year super(-1), indicating a positive net phosphorus input that can accumulate in the landscape or can pollute the water. Large positive NAPI values were associated with agricultural and developed land cover. County area-weighted NAPI increased from 4.43 to 4.94kgPha super(-1)year super(-1) between 1987 and 1997 but decreased slightly to 4.86 kgPha super(-1)ye ar super(-1) by 2002. Human population density, livestock unit density, and percent row crop land combined to explain 83% of the variability in NAPI among counties. Around 10% of total NAPI entering the Chesapeake Bay watershed is discharged into Chesapeake Bay. The developed land component of NAPI had a strong direct correlation with measured phosphorus discharges from major rivers draining to the Bay (R super(2)=0.81), however, the correlation with the simple percentage of developed land was equally strong. Our results help identify the sources of P in the landscape and evaluate the utility of NAPI as a predictor of water quality.

Male red-backed fairy-wrens Malurus melanocephalus exhibit 3 behaviorally distinct types in their first breeding season: breed in bright nuptial plumage, breed in dull plumage, or remain as an unpaired auxiliary (helper) with dull plumage. The retention of dull plumage by auxiliaries and dull breeders is an example of delayed plumage maturation (DPM), a widespread phenomenon in birds whose costs and benefits are not well understood. At a mechanistic level, DPM might allow dull males either to deceptively mimic females (female mimicry hypothesis) or to honestly signal their subordinate status (status-signaling hypothesis). DPM might function via either mechanism to provide ultimate benefits relative to developing nuptial plumage by increasing reproductive success, survival, or both. In this study, we tested the hypothesis that DPM is related to increased male survival in the red-backed fairy-wren via either female mimicry or status signaling. Aviary-based experiments revealed that dull males were perceived as male, which is consistent with the status-signaling hypothesis but contradicts the female mimicry hypothesis. Further aviary and field-based experiments also revealed that dull males were socially subordinate to bright males and received less aggression than bright males, further evidence for status signaling. However, male survival was not related to plumage coloration or breeding status. These findings indicate that male plumage coloration signals social status but that dull plumage does not afford a net survival advantage, perhaps because plumage color is a conditional strategy.

Dam removal has great potential for restoring rivers and streams, yet limited data exist documenting recovery of associated biota within these systems following removals, especially on larger systems. This study examined the effects of a dam breach on benthic macroinvertebrate and fish assemblages in the Fox River, Illinois, U.S.A.2. Benthic macroinvertebrates and fish were collected above and below the breached dam and three nearby intact dams for 1year pre- and 3years post-breach (2years of additional pre-breach fish data were obtained from previous surveys). We also examined the effects of the breach on associated habitat by measuring average width, depth, flow rate and bed particle size at each site.3. Physical habitat at the former impoundment (IMP) became comparable to free-flowing sites (FF) within 1year of the breach (width and depth decreased, flow rate and bed particle size increased). We also found a strong temporal effect on depth and flow rate at all surveyed sites.4. Following the breach, relative abundance of Ephemeroptera, Plecoptera and Trichoptera (largely due to hydropsychid caddisflies) increased, whereas relative abundance of Ostracoda decreased, in the former IMP to levels comparable to FF sites. High variation in other metrics (e.g. total taxa, diversity) precluded determination of an effect of the breach on these aspects of the assemblage. However, non-metric multidimensional scaling (NMDS) ordinations indicated that overall macroinvertebrate assemblage structure at the former IMP shifted to a characteristically FF assemblage 2years following the breach.5. Total fish taxa and a regional fish index of biotic integrity became more similar in the former IMP to FF sites following the breach. However, other fish metrics (e.g. biomass, diversity, density) did not show a strong response to the breach of the dam. Ordinations of abundance data suggested the fish assemblage only slightly shifted to FF characteristics 3years after the breach.6. Effects of the breach to the site immediately below the former dam included minor alterations in habitat (decreased flow rate and increased particle size) and short-term changes in several macroinvertebrate metrics (e.g. decreased assemblage diversity and EPT richness for first post-year), but longer-term alterations in several fish metrics (e.g. decreased assemblage richness for all three post-years; decreased density for first two post-years). However, NMDS ordinations suggested no change to overall assemblage structure for both macroinvertebrates and fish following the breach at this downstream site.7. Collectively, our results support the effectiveness of dam removal as a restoration practice for impaired streams and rivers. However, differences in response times of macroinvertebrates and fish coupled with the temporal effect on several habitat variables highlight the need for longer-term studies.

AN - 20693842; 8224836 AB - When species converge in their colour patterns because of mimicry, and those patterns are also used in mate recognition, there is a probability of conflicting selection pressures. Closely related species that mimic one another are particularly likely to face such confusion because of similarities in their courtship behaviour and ecology. We conducted experiments in greenhouse conditions to study interspecific attraction between two mimetic butterfly species, Heliconius erato and Heliconius melpomene. Both species spent considerable time approaching and courting females of the co-mimic species. Experiments using wing models demonstrated the importance of colour pattern in this interspecific attraction. Although males of H. melpomene were attracted to their co-mimics as much as to their own females, H. erato males were more efficient at distinguishing conspecifics, possibly using wing odours. Although preliminary, these results suggest that the use of additional cues may have evolved in H. erato to reduce the cost of convergence in visual signals with H. melpomene. Overall, our results showed that there might be a cost of mimetic convergence because of a reduction in the efficiency of species recognition. Such cost may contribute to explain the apparently stable diversity in Muellerian mimetic patterns in many tropical butterfly assemblages.

We present a case study of the koa-finches, genus Rhodacanthis, an extinct group of Hawaiian honeycreepers that was specialized to feed on green pods and seeds of the koa tree or other leguminous plants. Six island populations of koa-finches are known; four in the Holocene fossil record and two that survived until the 1890s. We document the palaeoecological context of the fossils and identify constraints on the age span of the specimen record for each population using stratigraphic contexts, associated radiometric determinations, and museum specimen data. We estimate the potential geographical range of koa-finches at the time of human arrival using two methods: assessment of their historical and palaeo-habitats, and geographical information system mapping of the pre-human distribution of the koa plant (Acacia koa) and its sister species, the koai'a plant (Acacia koaia). After integrating the foregoing data with chronological records and distributional maps of the potential forcing agents of extinction, we conclude that at least two extinctions of island populations were due to ecological change in the lowlands in the prehistorical and perhaps the early historical periods. In the same time frame, the koa-finch populations on Hawai'i Island became rare and restricted to upland refugia, making them vulnerable to the upland forest harvesting and degradation that was accelerating in the 1890s. Neither climatic variation nor mosquito-vectored diseases are likely to have caused the observed extinctions. This study illustrates an approach that can be applied to many other extinct and endangered island species to better understand the causes of high extinction rates in the human era.

We assessed genetic and phenotypic differentiation in 482 individuals representing 27 populations of the Mexican jay (Aphelocoma ultramarina) - a widespread bird species of the Mexican highlands - to test whether populations in the central and northern Mexican sierras display discrete breaks between groups, which would be consistent with a role for the different mountain chains in divergence and speciation. We found abrupt breaks in mitochondrial DNA (mtDNA; ND2 and control region) delineating four major genetic groups found in the Sierra Madre Occidental, Sierra Madre Oriental, southern Central Plateau (Bajio), and Transvolcanic Belt. These mtDNA groups were largely corroborated by data from nuclear microsatellites and phenotypic data, except that clades from the Central Plateau and Sierra Madre Oriental showed clinal change in these data sets. Uncertainty about the mutation rate for our mitochondrial markers warrants considerable caution with regard to estimating divergence times, but the major genetic groups appear to have split before the most extreme period of glacial cycling that marked the last 0.7 million years and after Mexico's period of major mountain formation. The fact that some genetic breaks do not coincide with well-known geographic barriers suggests a role for ecology in divergence and speciation, and we discuss implications for taxonomy and conservation.

The labrum is expressed as a simple fold which does not cover the mouth. A poorly-sclerotized mouth tube was observed on some specimens of all stages except NI (= naupliar stage 1); NI and NII are the only stages without an anus and presumably do not feed. The antennal endopod is a subchela against itself at NII; its distal endopodal segment becomes bifurcate at NIII. A chela on the naupliar mandible consists of the endopod opposite a distoventral attenuation of the basis on NII-NVI. The segmental elements of a chela are present at NI, although the endopod does not oppose the basis at this stage. The maxillule is a unilobe bud with one seta at NIII that gains a second seta at NV and is transformed into a simple bilobe bud with three setae at NVI. The maxilla and maxilliped are each an asetose, ventral attenuation at NVI. Naupliar stages, found in large numbers along with all six copepodid stages of T. falcatus, apparently feed on suctorian ciliates growing on colonies of the bryozoan Flustra foliacea (Linnaeus, 1758). This is the first description of six naupliar stages for a species of Tegastidae Sars, 1904.

Sedentary individuals are larger than migrants in all traits except bill width and depth. However, when traits are adjusted for body size differences using multivariate approaches, migrants have longer and more concave wings than do individuals from sedentary populations, suggesting selection for high-aspect ratio wings for fast, sustained flight. Subadults have relatively shorter and rounder wings than do adults of all subspecies except for the long-distance migrant D. c. coronata, and age-related differences are most pronounced in short-distance migrants. We propose a graphic model for the evolution of age-related differences in wing shape that is based on the role of antagonistic selective pressures imposed by migratory flight vs. maneuverability. Size-adjusted differences in tail length are not significant. Longer culmens and tarsi in the sedentary D. c. goldmani subspecies of Guatemala suggest differences in diet and foraging behavior compared to migratory groups. Our results strongly suggest that divergent natural selection has caused the morphological differentiation between migratory and sedentary subspecies.

Many sedentary organisms, unable to move to avoid hypoxic areas, have metabolic and behavioral adaptations to hypoxic stress. We tested the effects of hypoxia on the behavior and mortality of the clam Macoma balthica, using four levels of dissolved oxygen in flow-through tanks. We used five replicates of each of four treatments: (1) Hypoxic (DO mean+/-SE=1.1+/-0.06 mg O sub(2) l super(-) super(1)), (2) Moderately hypoxic (DO 2.6+/-0.05 mg O sub(2) l super(-) super(1)), (3) Nearly normoxic (DO 3.2+/-0.04 mg O sub(2) l super(-) super(1)), (4) Normoxic (DO=4.9+/-0.13 mg O sub(2) l super(-) super(1)). We lowered the dissolved oxygen with a novel fluidized mud-bed, designed to mimic field conditions more closely than the common practice of solely bubbling nitrogen or other gasses. This method for lowering the DO concentrations for a laboratory setup was effective, producing 1.4 l min super(-) super(1) of water with a DO of 0.8 mg O sub(2) l super(-) super(1) throughout the experiment. The setup greatly reduced the use of compressed nitrogen and could easily be scaled up to produce more low-DO water if necessary. The lethal concentration for 50% of the M. balthica population (LC sub(5) sub(0)) was 1.7 mg O sub(2) l super(-) super(1) for the 28-day experimental period. M. balthica decreased its burial depth under hypoxic and moderately hypoxic ( arrow up .5 mg O sub(2) l super(-) super(1)) conditions within 72 hours of the onset of hypoxia. By the sixth day of hypoxia the burial depth had been reduced by 26 mm in the hypoxic tanks and 10 mm in the moderately hypoxic tanks. Because reduced burial depth makes the clams more vulnerable to predators, these results indicate that the sub-lethal effects of hypoxia could change the rate of predation on M. balthica in the field.

Here, we reconstruct the major evolutionary transitions that produced the five distinct agricultural systems of the fungus-growing ants, the most well studied of the nonhuman agriculturalists. We do so with reference to the first fossil-calibrated, multiple-gene, molecular phylogeny that incorporates the full range of taxonomic diversity within the fungus-growing ant tribe Attini. Our analyses indicate that the original form of ant agriculture, the cultivation of a diverse subset of fungal species in the tribe Leucocoprineae, evolved approximately 50 million years ago in the Neotropics, coincident with the early Eocene climatic optimum. During the past 30 million years, three known ant agricultural systems, each involving a phylogenetically distinct set of derived fungal cultivars, have separately arisen from the original agricultural system. One of these derived systems subsequently gave rise to the fifth known system of agriculture, in which a single fungal species is cultivated by leaf-cutter ants. Leaf-cutter ants evolved remarkably recently ( approximately 8-12 million years ago) to become the dominant herbivores of the New World tropics. Our analyses identify relict, extant attine ant species that occupy phylogenetic positions that are transitional between the agricultural systems.

We experimentally partitioned bird predation from bat predation in a lowland tropical forest in Panama and measured the direct effects (arthropod abundance) and indirect effects (herbivory). The exclusion of birds and bats each directly increased arthropod abundance on plants: Bird-exclosed plants contained 65% more, and bat-exclosed plants 153% more, arthropods than controls. Birds and bats also indirectly increased herbivory: Bird-exclosed plants suffered 67% more, and bat-exclosed plants 209% more, herbivory than controls. We conclude that bats have dramatic ecological effects that were previously overlooked.

The 300 and 100 K palygorskite structures in air compare well with previous models but provide additional details about zeolitic H (sub 2) O sites and reveal that the Al atoms are ordered into the inner M2 octahedral sites and the Mg cations into the M3 sites at the edges of the tunnels. Real-time, temperature-resolved synchrotron powder X-ray diffraction data and Rietveld refinements were used to investigate the monoclinic palygorskite structure from 300 to 1400 K (in air). Rietveld refinements showed that most of the zeolitic H (sub 2) O is lost by approximately 425 K, accompanied by a decrease in the unit-cell volume of 1.3%, primarily owing to a decrease in the a unit-cell parameter and an increase in the beta angle. The structurally bound H (sub 2) O is lost in two stages, at temperature intervals of 475-540 and 580-725 K. Above approximately 825 K in air a portion of the Korean sample transformed to a folded structure; the Alaskan sample folded at approximately 575 K under vacuum. A structure model was refined for the folded structure. At approximately 1015 K for the sample heated in air, beta -quartz diffraction peaks appeared and increased in intensity as heating continued to the maximum temperature. Cristobalite formed above approximately 1050 K, along with a small amount of clinoenstatite, and both phases persisted to the maximum temperature studied.

The planktonic foraminiferal zonation is based on standard global biozones for this interval, but rare and sporadic occurrence of two zonal biomarkers, Gansserina gansseri and Globotruncana aegyptiaca, precludes reliable identification of the nominate zones for those species. The Pseudoguembelina palpebra Partial-range Zone is defined as a means of subdividing this upper Campanian biostratigraphic interval. Planktonic foraminiferal, calcareous nannofossil and paleomagnetic datums are integrated to construct reliable age-depth curves for each of the Blake Nose drill sites. These age models are largely confirmed by Sr-isotopic data and suggest significant unconformities at various positions within the sections. Compilation of stable isotope datasets for this time interval from the Blake Nose sites reveals no significant shifts in delta (super 18) O and delta (super 13) C at the time of the inoceramid bivalve extinction (now dated as 68.5-68.7 Ma in the Blake Nose sections) and no correlation with proposed Campanian-Maastrichtian glacial intervals. However, benthic warming associated with Deccan volcanism during the late Maastrichtian is supported.

AN - 51079322; 2008-082518 AB - Rhyolitic eruptions often begin explosively and then shift to extrusions of lava. It is widely believed that the style of eruption is dependent on magma flow rate within the conduit, fast ascent leading to explosive eruption and slow ascent favoring effusive behavior. Currently, the velocity of rhyolite magma flowing in a conduit is unknown, and therefore eruption models remain untested against geologic evidence of magma ascent. We show that explosively erupted rhyolite magma from the Inyo volcanic chain ascended slowly (centimeters per second), at same rates as the dome-building phases. We propose that the explosive-effusive transition sub-Plinian rhyolite eruptions is governed by the alleviation of exsolved volatile pressure in the shallow conduit rather than the magma flow rate.

Beringian paleontological records store a wealth of information that can be used to investigate how predator-prey and competitive interactions among consumers shifted in response to past episodes of environmental change. Two such recent periods of rapid climate change are the Last Glacial Maximum (LGM) and the end of glacial conditions at the beginning of the Holocene. Here we assemble carbon and nitrogen stable isotope, and AMS (super 14) C data collected from bone collagen of late Pleistocene carnivores and megafaunal prey species from the interior of eastern Beringia (Alaska), and reconstruct the diets of ancient Alaskan carnivores and herbivores. We are able to account for the relative influences of diet versus changing environmental conditions on variances in consumer isotope values, to identify species hiatuses in the fossil record, and to draw conclusions about paleoenvironmental conditions from faunal chronologies. Our isotopic results suggest that there was dietary niche overlap among some Beringian herbivore species, and partitioning among other species. We rely upon delta (super 13) C and delta (super 15) N values of modern Alaskan C (sub 3) plant types to infer Beringian herbivore dietary niches. Horse, bison, yak, and mammoth primarily consumed grasses, sedges, and herbaceous plant species. Caribou and woodland muskox focused upon tundra plants, including lichen, fungi, and mosses. The network of Beringian carnivore interaction was complex and dynamic; some species (wolves) persisted for long periods of time, while others were only present during specific timeframes (large felids and ursids). Beringian carnivore diets included all measured herbivore species, although mammoth and muskox only appeared in carnivore diets during specific times in the late Pleistocene. We identified the potential presence of unmeasured diet sources that may have included forest-dwelling cervids and/or plant materials. None of the large-bodied carnivore species we analyzed (except short-faced bear) were specialized predators of a single prey species during the late Pleistocene. Differences in carnivore diet and dietary breadth between time periods either reflect changes in the relative abundances of prey on the Beringian landscape, or changes in competitive interactions among Beringian carnivore species.

Near-infrared spectra of CAIs have strong 2-micrometer absorptions, attributed to iron oxide-bearing aluminous spinel. Similar absorptions are present in the telescopic spectra of several asteroids; modeling indicates that these contain approximately 30 + or - 10% CAIs (two to three times that of any meteorite). Survival of these undifferentiated, large (50- to 100-kilometer diameter) CAI-rich bodies suggests that they may have formed before the injection of radiogenic (super 26) Al into the solar system. They have also experienced only modest post-accretionary alteration. Thus, these asteroids have higher concentrations of CAI material, appear less altered, and are more ancient than any known sample in our meteorite collection, making them prime candidates for sample return.

The accretionary rims around Leoville, Vigarano, and Allende CAIs exhibit a layered structure: the inner layer consists of coarse-grained, forsteritic and (super 16) O-rich olivine (Fa (sub 1-40) and Delta (super 17) O=-24 ppm to -5 ppm; the higher values are always found in the outer part of the layer and only in the most porous meteorites), whereas the middle and the outer layers contain finer-grained olivines that are more fayalitic and (super 16) O-depleted (Fa (sub 15-50) and Delta (super 17) O=-18 ppm to +1 ppm). The CV matrices and accretionary rims around chondrules have olivine grains of textures, chemical and isotopic compositions similar to those in the outer layers of accretionary rims around CAIs. There is a correlation between local sample porosity and olivine chemical and isotopic compositions: the more compact regions (the inner accretionary rim layer) have the most MgO- and (super 16) O-rich compositions, whereas the more porous regions (outer rim layers around CAIs, accretionary rims around chondrules, and matrices) have the most MgO- and (super 16) O-poor compositions. In addition, there is a negative correlation of olivine grain size with fayalite contents and Delta (super 17) O values. However, not all fine-grained olivines are FeO-rich and (super 16) O-poor; some small (20) ) olivine grains in the outer layers of the CAI accretionary rims and in the matrix show significant enrichments in (super 16) O (Delta (super 17) O=-20 ppm to -10 ppm). We infer that the inner layer of the accretionary rims around CAIs and, at least, some olivine grains in the finer portions of accretionary rims and CV matrices formed in an (super 16) O-rich gaseous reservoir, probably in the CAI-forming region. Grains in the outer layers of the CAI accretionary rims and in the rims around chondrules as well as matrix may have also originated as (super 16) O-rich olivine. However, these olivines must have exchanged O isotopes to variable extents in the presence of an (super 16) O-poor reservoir, possibly the nebular gas in the chondrule-forming region(s) and/or fluids in the parent body. The observed trend in isotopic compositions may arise from mixtures of (super 16) O-rich forsterites with grain overgrowths or newly formed grains of (super 16) O-poor fayalitic olivines formed during parent body metamorphism. However, the observed correlations of chemical and isotopic compositions of olivine with grain size and local porosity of the host meteorite suggest that olivine accreted as a single population of (super 16) O-rich forsterite and subsequently exchanged Fe-Mg and O isotopes in situ in the presence of aqueous solutions (i.e., fluid-assisted thermal metamorphism).

This result, along with the chemical systematics of the highly siderophile elements (HSE) are indicative of closed-system behavior for all of the HSE in the IVB system since crystallization. Abundances of HSE measured in different chunks of individual bulk samples, and in spot analyses of different portions of individual chunks, are homogeneous at the + or -10% level or better. Modeling of HSE in the IVB system, therefore, is not impacted by sample heterogeneities. Concentrations of some other elements determined by spot analysis, such as P, Cr and Mn, however, vary by as much as two orders of magnitude and reflect the presence of trace phases. Assuming initial S in the range of 0 to 2 wt.%, the abundances of the HSE Re, Os, Ir, Ru, Pt, Rh, Pd and Au in bulk IVB irons are successfully accounted for via a fractional crystallization model. For these elements, all IVB irons can be interpreted as being representative of equilibrium solids, liquids, or mixtures of equilibrium solids and liquids. Our model includes changes in bulk D values (ratio of concentration in the solid to liquid) for each element in response to expected increases in S and P in the evolving liquid. For this system, the relative D values are as follow: Os>Re>Ir>Ru>Pt>Rh>Pd>Au. Osmium, Re, Ir and Ru were compatible elements (favor the solid) throughout the IVB crystallization sequence; Rh, Pd and Au were incompatible (favor the liquid). Extremely limited variation in Pt concentrations throughout the IVB crystallization sequence requires that D(Pt) remained at unity. In general, D values derived from the slopes of logarithmic plots, compared with those calculated from recent parameterizations of D values for metal systems are similar, but not identical. Application of D values obtained by the parameterization method is problematic for comparisons of the compatible elements with similar partitioning characteristics. The slope-based approach works well for these elements. In contrast, the slope-based approach does not provide viable D values for the incompatible elements Pd and Au, whereas the parameterization method appears to work well. Modeling results suggest that initial S for this system may have been closer to 2% than 0, but the elements modeled do not tightly constrain initial S. Consistent with previous studies, our calculated initial concentrations of HSE in the IVB parent body indicate assembly from materials that were fractionated via high temperature condensation processes. As with some previous studies, depletions in redox sensitive elements and corresponding high concentrations of Re, Os and Ir present in all IVB irons are interpreted as meaning that the IVB core formed in an oxidized parent body. The projected initial composition of the IVB system was characterized by sub-chondritic Re/Os and Pt/Os ratios. The cause of this fractionation remains a mystery. Because of the refractory nature of these elements, it is difficult to envision fractionation of these elements (especially Re-Os) resulting from the volatility effects that evidently affected other elements.

Previous geologists envisioned a meandering river with crevasse splays that disgorged gray mud on top of the peat, like the modern "bird's foot" Mississippi delta. New information, including closely-spaced core drilling and mine entries driven across the channel, directs us to a new model of channel origin. This model conforms with the sediment climate model developed by Blaine Cecil and colleagues. During eustatic lowstand prior to Springfield peat, the region underwent subaerial exposure, soil formation (underclay), and valley incision under a seasonal wet-dry climate. Rivers carried dominantly sand and meandered actively, as Paul Potter mapped during the early 1960s. Eventually basin subsidence and change from seasonal to ever-wet climate initiated development of Springfield peat. Dense vegetation now locked meanders in place while greatly reducing runoff. The Galatia channel became a black-water stream that carried only suspended clay and organic sediment. Peat and clay were thinly interlaminated along channel margins. Finally, eustatic sea-level rise, brought about by glacial melting, drowned the peat mire. A simultaneous return to seasonal climate suppressed upland vegetation and liberated sediment transport. The Galatia channel now became an estuary with much greater flow and sediment volume. Thick gray clay, silt and fine sand (Dykersburg Shale) rapidly buried the Springfield peat, compressing it and making space for more sediment. As previous geologists understood, Springfield Coal covered by thick Dykersburg Shale has low sulfur content because it was shielded from later sulfide-bearing marine water and sediment.

With compositions ranging from basanite to lamprophyre, these rocks are distinct from, yet intimately associated with the andesitic volcanism that is prominent in the area. We interpret the most primitive magmas as representing nearly pure partial melts of phlogopite-rich veins in the mantle, that with dilution by peridotite melting result in the calc-alkaline basalts that differentiate to form andesites. High concentrations of volatiles in some glass inclusions and estimates of magmatic fO (sub 2) from bulk-rock Fe (sub 3+) /Fe (sub 2+) and glass-inclusion %S (super 6+) indicate a volatile-rich and highly oxidized (several log units above the Ni-NiO buffer) environment. The highest volatile contents (7% H (sub 2) O, 1460 ppm CO (sub 2) , approximately 2% SO (sub 3) (super Total) , 2400 ppm Cl, and approximately 1% F) were recorded for an inclusion from a Colima minette (phlogopite-bearing lamprophyre). A calculated gas saturation pressure of 6660 bars for this sample corresponds to a depth of 24.1 km. This magma can be modeled as a parent to most other glass inclusions under closed-system degassing with a high wt.% exsolved vapor. This model is consistent with curious inclusions with multiple bubbles, from a Mascota minette, that appear to represent entrapment of a foaming melt. It is notable that many of the inclusions from minettes contain 2% water or less. Given the wide variations in water content and relatively poor correlation with K, P, S, and Cl, diffusion of H through the olivine host may be partially responsible. However, it is reasonable to assume that glass inclusions get trapped at different stages along the ascent path. A value of 2% water corresponds to water saturation at a pressure of 415 bars (1600 m. depth). Published phase-equilibrium experiments on an olivine-bearing minette imply that phlogopite is stable down to pressures of 200-400 bars, allowing the possibility that these low-water inclusions were trapped at shallow depth. The range in volatile contents, the degassing model, and the presence of vesicular glass inclusions are consistent with olivine crystallization at depth (24 km), followed by rapid ascent and degassing, and then stagnation in the upper crust, where olivine continued to crystallize and trap inclusions of melt.

However, spectacular exposures in underground mines support a different origin, not previously considered, for some of the splits. Significant observations include (1) absence of roots and paleosols beneath upper coal benches, (2) absence of buried tree stumps (common elsewhere in these mines) on top of lower benches, (3) ragged coal stringers that splay off the undersides of upper benches, (4) uniform lithology above, below, and lateral to split coal, (5) abundant stringers and mats of coal within splits, and (6) prevalence of tidal rhythmites in splits. Splits that bear these features range from tens to hundreds of meters long and as thick as 15 meters. In some cases coal benches reunite, in others the coal terminates against clastic rocks. We propose that these splits formed after Springfield peat was completely formed. The setting was an estuary as eustatic transgression drowned the peat mire. Buoyed by trapped gas and hammered by tides, upper peat layers tore free and floated upward. Silt then passively filled the space beneath the floating mats.

Although clearly referable to the Buteoninae, its relationships within that group are difficult to assess. Considerable size variation may be attributable to sexual dimorphism associated with bird-catching behavior. It is uncertain if the species survived into the historic period. Factors contributing to the rarity of hawk remains in the fossil record of Bermuda are discussed. One fragmentary ulna is from a larger hawk, possibly the Red-tailed Hawk Buteo jamaicensis.

Little is known about how conversion of native grasslands to Juniperus-dominated forests alters soil nutrient availability and ecosystem storage of carbon (C) and nitrogen (N), although such land-cover changes have important implications for local ecosystem dynamics, as well as regional C and N budgets. Four replicate native grasslands and adjacent areas of recent J. virginiana encroachment were selected to assess potential changes in soil N availability, leaf-level photosynthesis, and major ecosystem C and N pools. Net N mineralization rates were assessed insitu over two years, and changes in labile soil organic pools (potential C and N mineralization rates and microbial biomass C and N) were determined. Photosynthetic nitrogen use efficiencies (PNUE) were used to examine differences in instantaneous leaf-level N use in C uptake. Comparisons of ecosystem C and N stocks revealed significant C and N accrual in both plant biomass and soils in these newly established forests, without changes in labile soil N pools. There were few differences in monthly insitu net N mineralization rates, although cumulative annual net N mineralization was greater in forest soils compared to grasslands. Conversely, potential C mineralization was significantly reduced in forest soils. Encroachment by J. virginiana into grasslands results in rapid accretion of ecosystem C and N in plant and soil pools with little apparent change in N availability. Widespread increases in the cover of woody plants, like J. virginiana, in areas formerly dominated by graminoid species suggest an increasing role of expanding woodlands and forests as regional C sinks in the central U.S. JF - Ecosystems AU - McKinley, Duncan C AU - Blair, John M AD - Smithsonian Environmental Research Center, 647 Contees Wharf Road, P.O.

Effective reduction of these threats requires identification of variables influencing collision locations, and the use of these variables in spatially-explicit predictive models. We used Penrose distance modeling and 61 confirmed bobcat (Lynx rufus) road mortality locations in southern Illinois, USA, to demonstrate a rapid and accurate technique for the spatial mapping of wildlife-vehicle collision risk. We used the Penrose distance statistic to quantify the similarity between the mean multivariate habitat signature at bobcat-collision areas and road sections throughout the study area. Habitat variables assessed included road-related variables (e.g., traffic volume) and land cover characteristics (e.g., mean patch area of the landscape). Bobcat-collision areas were characterized by smaller, less-clustered habitat patches and more, large independent patches of grass cover than were study area roadway sections in general. As expected for a generalist carnivore in highly-suitable habitat, risk mapping indicated that large sections of the roaded landscape had high similarity to bobcat-collision areas. Unlike other modeling techniques used to identify risk of road mortality, our method requires little field data collection and relies on readily available digital spatial data. This technique can be used by wildlife managers and road planners, and may be particularly important in reduction of road mortality for species such as the Iberian lynx (Lynx pardinus), Florida panther (Puma concolor coryi), and Texas ocelot (Leopardis pardalus), which exist in small populations fragmented by development, and are limited by road mortalities.

Signatures of parasite release could thus be used to resolve cryptogenic (uncertain) origins such as that of Littorina littorea, a European marine snail whose history in North America has been debated for over 100 years. Through extensive field and literature surveys, we examined species richness of parasitic trematodes infecting this snail and two co-occurring congeners, L. saxatilis and L. obtusata, both considered native throughout the North Atlantic. Of the three snails, only L. littorea possessed significantly fewer trematode species in North America, and all North American trematodes infecting the three Littorina spp. were a nested subset of Europe. Surprisingly, several of L. littorea's missing trematodes in North America infected the other Littorina congeners. Most likely, long separation of these trematodes from their former host resulted in divergence of the parasites' recognition of L. littorea. Overall, these patterns of parasitism suggest a recent invasion from Europe to North America for L. littorea and an older, natural expansion from Europe to North America for L. saxatilis and L. obtusata.

We investigated the utility of dissolved concentration measurements for 6 elements (Ba, P, Mn, U, V and Mo) in the ballast tanks of ships operating in the North Pacific and Atlantic oceans as tracers of mid-ocean BWE. Relatively conservative elements Mo, U and V provided little additional information beyond that obtained from salinity, whereas nonconservative Ba, P and Mn offered greater resolution. The utility of Ba, P and Mn was further examined in the context of three criteria: (1) stability, or whether tracers maintain stable concentrations in ballast tanks over time; (2) fidelity, or the degree to which tracer concentrations in ballast tanks faithfully reflect concentrations at their ocean source; and (3) predictability, or the degree to which ballast tanks have a predictable and restricted range of tracer concentrations following BWE. We found that in water held in ballast tanks over time, average stability increased for Mn21%>3%) and fidelity increased in the same direction. While Ba and P usually increased discrimination at high salinities, Mn was typically the most sensitive indicator of BWE and the presence of residual port water in partially exchanged tanks. Ba, P and Mn in tanks exchanged in the Atlantic exhibited different concentration ranges compared to tanks exchanged in the Pacific, suggesting that if trace elements are to be used to verify BWE, criteria for discriminating between exchanged and unexchanged ballast tanks may need to be basin-specific.

In grasslands, changes in resource availability can occur at broad spatial scales and enlarge area requirements of ungulate populations, which increases their vulnerability to habitat loss and fragmentation. Understanding and predicting these dynamics, although critical, has received little attention so far.We investigated habitat dynamics for Mongolian gazelles (Procapra gutturosa Pallas) in the eastern steppes of Mongolia. We quantified the distribution of gazelles at four different time periods and tracked primary productivity using Normalized Difference Vegetation Index (NDVI) data from satellite imagery.A second-order logistic model showed that NDVI was an efficient predictor of gazelle presence. We tested the predictive power of the model with independent data from a gazelle telemetry study: 85% of all relocations were found within the predicted area.Gazelles preferred an intermediate range of vegetation productivity, presumably facing quality quantity trade-offs where areas with low NDVI are limited by low ingestion rates, and areas with high NDVI are limited by the low digestibility of mature forage.Spatiotemporal variation of gazelle habitat areas was high. Only 15% of the study area was consistently gazelle habitat throughout all survey periods, indicating that gazelles need to range over vast areas in search of food. Only 1% of the gazelle habitats were consistently located inside protected areas.Synthesis and applications. Habitat variability in grasslands often leads to area requirements of ungulates that prevent effective conservation within single protected areas. They require landscape-level management plans, but dynamic habitat predictions to inform such plans are difficult to implement and are often unavailable. We showed that satellite estimates of vegetation productivity can be used successfully to generate dynamic habitat models in landscapes with highly variable resources, and demonstrated that intermediate NDVI values were critical to predict occurrence of Mongolian gazelles.

We detected significant but limited geographic structuring of haematozoan parasite lineages across the breeding range of the redstart. We found that redstarts from the south-eastern (SE) region of the breeding range had a significantly different haematozoan parasite assemblage compared with populations sampled throughout the rest of the breeding range. Evidence using stable isotopes from feathers previously demonstrated that redstarts from the SE of the breeding range also have a unique and separate wintering range. Thus, although two methods of estimating migratory connectivity have now both shown the SE US breeding sub-population of redstarts to be distinct from other populations on both the breeding and wintering grounds, conclusive migratory connectivity for this species as a whole could not be established.

The variation in bird effects may be due to characteristics such as plant productivity or quality, habitat complexity, and/or species diversity of predator and prey assemblages. Since agroforestry systems vary in such characteristics, these systems provide a good starting point for understanding when and where we can expect predation by birds to be important. We analyze data from bird exclosure studies in forests and agroforestry systems to ask whether birds consistently reduce their arthropod prey base and whether bird predation differs between forests and agroforestry systems. Further, we focus on agroforestry systems to ask whether the magnitude of bird predation (1) differs between canopy trees and understory plants, (2) differs when migratory birds are present or absent, and (3) correlates with bird abundance and diversity. We found that, across all studies, birds reduce all arthropods, herbivores, carnivores, and plant damage. We observed no difference in the magnitude of bird effects between agroforestry systems and forests despite simplified habitat structure and plant diversity in agroforests. Within agroforestry systems, bird reduction of arthropods was greater in the canopy than the crop layer. Top-down effects of bird predation were especially strong during censuses when migratory birds were present in agroforestry systems. Importantly, the diversity of the predator assemblage correlated with the magnitude of predator effects; where the diversity of birds, especially migratory birds, was greater, birds reduced arthropod densities to a greater extent. We outline potential mechanisms for relationships between bird predator, insect prey, and habitat characteristics, and we suggest future studies using tropical agroforests as a model system to further test these areas of ecological theory.

However, the role of such features in habitat selection and demography of individual species has not been established. Understanding the mechanisms of habitat selection requires both experimental manipulation of habitat structure and detailed estimation of the behavioral and demographic response of animals, e.g., changes in movement patterns and survival probabilities. Such studies have not been conducted in natural tropical forest, perhaps because of high habitat heterogeneity, high species diversity, and low abundances of potential target species. Agroforestry systems support a less diverse flora, with greater spatial homogeneity which, in turn, harbors lower overall species diversity with greater numerical dominance of common species, than natural forests. Furthermore, agroforestry systems are already extensively managed and lend themselves easily to larger scale habitat manipulations than protected natural forest. Thus, agroforestry systems provide a good model environment for beginning to understand processes underlying habitat selection in tropical forest animals. Here, we use multistate, capture-recapture models to investigate how the experimental removal of epiphytes affected monthly movement and survival probabilities of two resident bird species (Common Bush-Tanager [Chlorospingus ophthalmicus] and Golden-crowned Warbler [Basileuterus culicivorus]) in a Mexican shade coffee plantation. We established two paired plots of epiphyte removal and control. We found that Bush-Tanagers were at least five times more likely to emigrate from plots where epiphytes were removed compared to control plots. Habitat-specific movement patterns were not detected in the warbler. However, unlike the Golden-crowned Warbler, Common Bush-Tanagers depend upon epiphytes for nest sites and (seasonally) for foraging. These dispersal patterns imply that active habitat selection based on the presence or absence of epiphytes occurs in C. ophthalmicus on our study area. Survival rates did not vary with habitat in either species. Interestingly, in both species, survival was higher in the nonbreeding season, when birds were in mixed-species flocks. Movement by Common Bush-Tanagers into areas with epiphytes occurred mostly during the breeding season, when mortality-driven opportunity was greatest.

A striking case is the common geographically and ecologically widespread neotropical skipper butterfly Perichares philetes (Lepidoptera, Hesperiidae), described in 1775, which barcoding splits into a complex of four species in Area de Conservacion Guanacaste (ACG) in northwestern Costa Rica. Three of the species are new, and all four are described. Caterpillars, pupae, and foodplants offer better distinguishing characters than do adults, whose differences are mostly average, subtle, and blurred by intraspecific variation. The caterpillars of two species are generalist grass-eaters; of the other two, specialist palm-eaters, each of which feeds on different genera. But all of these cryptic species are more specialized in their diet than was the morphospecies that held them. The four ACG taxa discovered to date belong to a panneotropical complex of at least eight species. This complex likely includes still more species, whose exposure may require barcoding. Barcoding ACG hesperiid morphospecies has increased their number by nearly 10%, an unexpectedly high figure for such relatively well known insects.

We describe their ecology, focusing on demography, diet, and ranging patterns in 8 groups studied from 1995 to 1999. The groups averaged 4.3 individuals, with 1 breeding female and 1-2 adult males, and reproduction was seasonal. Evidence from nonstudy groups indicated the possibility of polygynous group structure. We observed group formation and the transfer of adults between groups. The marmosets ate 20 species of fruit and nectar and 5 exudate species. Home ranges were 34-39 ha, and daily path lengths averaged 1498 m. We include our data in a comprehensive review of eastern Brazilian marmosets to characterize their ecology. Callithrix kuhlii ate more fruit species and less gum species, and had larger home ranges and daily path lengths versus those of most congeners. There was also a tradeoff between travel time and other behaviors. Species with smaller home ranges spent more time foraging and resting and less time traveling than the ones with larger ranges. Attributes consistent with all species included their reliance on gum during fruit scarcity and preference for disturbed habitat. We explored factors relating to the variation in diet and ranging patterns within the eastern Brazilian marmosets, in particular by considering the species in relation to elevation and the extent and proximity of their distribution to the sea. However, large intraspecific variation resulting in part from variable levels of anthropogenic disturbance across sites confounded our ability to verify trends corresponding to the geographic characteristics.

A bilateral accord, a trilateral agreement, two regional memoranda of understanding, and a legally binding treaty - all specifically for marine turtle conservation - have been the subject of news flashes, progress reports, updates, scholarly evaluations, enthusiastic proclamations, and gloomy critiques. Recently the fervor for these instruments seems to have subsided, and basic questions need answers: What was developed? With what objective? What did it involve? How was it administered? What achievements have been made? How has turtle conservation been improved by these advances? In what ways were these international accords instrumental in achieving conservation goals? In what ways have they failed? The results to date are highly variable. One accord, accompanied by fanfare and enthusiastic proclamations, has yet to be consummated, affording minimal benefits to strengthening multi-lateral attitudes toward turtle conservation. An MoU, although initially providing tangible achievements - despite considerable odds, has been left to languish by a major inter-governmental organization, and been ignored by powerful States with clear interests and responsibilities in the region. On the other hand, a bilateral accord - the first of its kind, and winner of an international prize - has continued to nurture strong cooperation at the technical level, transcending severe problems at the highest political levels. A hemispheric treaty has disappointed conservationists throughout the region because of its lethargy in resolving basic administrative issues; yet, there have been tangible contributions and cultivation of inter-governmental interests in collaboration. The instrument covering the largest, most diverse area, with nearly two dozen Signatory States, has shown the most rapid advancement, easily overtaking other agreements that were developed before it, and producing various tangible advances promoting the conservation of turtles and their habitats. Yet, it too has much to resolve if it is to achieve its intended goals. Clearly, it is too early to determine whether any of these instruments has failed or succeeded in the conservation of the slow-maturing, long-lived, highly migratory reptiles for which they were developed. The interminable frustrations of administrative, bureaucratic, and political obstacles, to say nothing of the substantial expenditures in human and financial resources, make it easy to criticize these initiatives, especially from the insulated comfort of an ivory tower. But they must be viewed within the light of the realities of international relations; some essential treaties have taken decades just to be negotiated and adopted: short of military intervention, there is no simple way to robustly promote the widespread adoption of collaborative measures for the conservation of shared resources. Until an alternative less-worse than international instruments is devised for sponsoring multi-lateral cooperation in the ways that divergent human societies and governance levels interact with resources that they all share and impact, there is reason for hope that there will be a treat to these turtle treaties. There is also every reason for turtle conservationists to become better informed, and involved with international instruments.

Less attention has been directed toward upland ecosystems that cover far larger areas, but are assumed to be too dry to emit CH sub(4). Here we review CH sub(4) production and emissions in upland ecosystems, with attention to the influence of plant physiology on these processes in forests. Upland ecosystems are normally net sinks for atmospheric CH sub(4) because rates of CH sub(4) consumption exceed CH sub(4) production. Production of CH sub(4) in upland soils occurs in microsites and may be common in upland forest soils. Some forests switch from being CH sub(4) sinks to CH sub(4) sources depending on soil water content. Plant physiology influences CH sub(4) cycling by modifying the availability of electron donors and acceptors in forest soils. Plants are the ultimate source of organic carbon (electron donor) that microbes process into CH sub(4). The availability of O sub(2) (electron acceptor) is sensitive to changes in soil water content, and therefore, to transpiration rates. Recently, abiotic production of CH sub(4) from aerobic plant tissue was proposed, but has not yet been verified with independent data. If confirmed, this new source is likely to be a minor term in the global CH sub(4) budget, but important to quantify for purposes of greenhouse gas accounting. A variety of observations suggest that our understanding of CH sub(4) sources in upland systems is incomplete, particularly in tropical forests which are stronger sources then expected.

The resolution was 1.2 super([image] ), but because of high signal-to-noise ratio we measured the positions of all maser components to accuracies better than 0.01 super([image] ), at a velocity resolution of [image]. The two strongest maser components (called high-velocity components) at velocities near -14 and [image] are separated by [image] (60 AU) along a position angle of [image]. The distribution of maser emission at velocities between and beyond these two strongest components were also provided. The continuum emission lies at the center of the maser distribution to within 10 mas. The masers appear to trace a nearly edge-on rotating disk structure, reminiscent of the water masers in Keplerian rotation in the nuclear accretion disk of the galaxy NGC 4258. However, the maser components in MWC 349A do not follow a simple Keplerian kinematic prescription with [image], but have a larger power-law index. We explore the possibility that the high- velocity masers trace spiral density or shock waves. We also emphasize caution in the interpretation of relative centroid maser positions where the maser is not clearly resolved in position or velocity, and we present simulations that illustrate the range of applicability of the centroiding method.

Zooarcheological studies have long suggested that these animals are not native to the West Indies. Originally, Caribbean populations were described as endemic insular species Procyon maynardi (Bahamas), P. minor (Guadeloupe), and P. gloveralleni (Barbados), a classification that was recognized throughout much of the 20th century. More recently, studies of qualitative morphology and a review of historical publications and documents have been used to bolster arguments that these populations of raccoons are not unique species worthy of special conservation attention, but invasive populations of the North American raccoon (P. lotor) introduced in recent centuries. Raccoons in the Bahamas and the French Antilles appear to be spreading onto other islands with human assistance, but the population on Barbados is now apparently extinct. We present evidence from the mitochondrial control region, including sequence data from the extinct population on Barbados generated using ancient DNA protocols, indicating that all 3 major insular populations of West Indian raccoons are conspecific with P. lotor and probably originated via recent translocations from eastern North America. Like nonnative populations of raccoons that have been established elsewhere (e.g., in Alaska, Japan, and Europe), the raccoons of the West Indies deserve no special taxonomic recognition or conservation status. They may be destructive to native wildlife on West Indian islands where they have been introduced, particularly if their spread to and across other islands continues.

The burial dates to 3776 to 3690 carbon-14 years before the present (2155 to 1936 calendar years B.C.), making this the earliest worked gold recovered to date not only from the Andes, but from the Americas as well. This discovery lends support to the hypothesis that the earliest metalworking in the Andes was experimentation with native gold. The presence of gold in a society of low-level food producers undergoing social and economic transformations coincident with the onset of sedentary life is an indicator of possible early social inequality and aggrandizing behavior and further shows that hereditary elites and a societal capacity to create significant agricultural surpluses are not requisite for the emergence of metalworking traditions.

At the marl fen and two rich fen sites, hydrometric data and pore water samples collected from nested piezometers set along the GWF-path showed spatial patterns consistent with a mixing gradient established by the intersection of local (i.e., hill slope), relatively dilute groundwater discharge and mineral-rich groundwater discharged from a larger-scaled (i.e., intermediate) system. Distinct redox and carbonate gradients along the GWF-paths of three rich fens reflected strong interactions between groundwater supply of terminal electron acceptors and microbial processes affecting speciation of iron, nitrogen and phosphorus. Decreased nitrate concentrations, increased dissolved iron, and removal of sulfate along flowpaths indicated that redox conditions became more reduced as groundwater moved down-gradient. Nitrate removal occurred across the interface between the upland mineral soil and the organic-rich fen peat. Lack of ammonium accumulation indicated that denitrification limits N-supply to plants in down-gradient fen areas. Further down-gradient, sulfate-enriched groundwater discharge sustained sub-oxic conditions and enhanced phosphorus mobility through effects on iron-sulfur-phosphorus dynamics, alkalinity generation, and dissolution of mineral-bound P. In contrast, the poor fen was sustained by an isolated surficial groundwater system; a thick lacustrine clay aquitard limited intermediate or regional-scaled groundwater discharge. As a result, water table fluctuations were more responsive to short-term weather events and imposed the strongest influence on redox status. A redox gradient, evidenced by increasing iron and ammonium concentrations, extended downward with depth from the aerated peat surface. The dilute water supply and lack of additional internal alkalinity generation limited buffer capacity and decomposition. Overall, ammonium accumulation increased N-availability whereas reduced decomposition rates further limited P availability. Our results show that interaction of multiple GWF systems within the fens was the critical determinant of water table stability (rich fens) or fluctuation (poor fen), as well as the supply of dissolved ions that influence geochemical processes affecting plant nutrient availability. Together these factors accounted directly or indirectly for observed spatial patterns in redox and alkalinity gradients, which in turn controlled speciation of phosphorus-reactive minerals. Differences among fens in spatial patterns could be accounted for by differences in the geomorphometry of the basins within which the fens developed and the stratigraphy and hydraulic characteristics of underlying sediments. Results suggest that Fe-S dynamics, rather than carbonate precipitation, likely influences inorganic phosphorus pools and release mechanisms.

Here I report observations on the reproduction and development of Tylodina fungina (Gabb, 1865) from the Perlas Islands on the Pacific coast of Panama. This species lives, feeds, and lays flat egg ribbons on the verongid sponge Suberea azteca (Gomez and Bakus, 1992). The egg ribbons contain hundreds of rows of 80 mu m eggs, each singly encapsulated in a round 125 mu m capsule. The ribbon also includes strings of extra-capsular material which is unevenly distributed through the mass. The eggs have equal cleavage and the ciliated "trochophore" stage is followed by an encapsulated veliger, which has a large, dark-red pigmented mantle organ. At hatching the transparent, left-handed larval shell is 123 mu m long, and each semicircular velar lobe is unpigmented. There is a distinct operculum, but the eyes and tentacles have not developed. After 3 weeks in culture the larvae had reached a shell length of 162 mu m and still had no eyes or tentacles. The larvae did not survive to settlement.

In spite of the importance of these species, relatively little is known about their regeneration ecology and little effort has gone into understanding the reasons for the consistently reported regeneration failures after logging. I assessed seed survival to germination (Entandrophragma angolense) and seedling survivorship (E. cylindricum) in three different forest types - monodominant Gilbertiodendron, mixed species, and fallow forest - under three different treatments - control, small mesh chicken wire, and large mesh chicken wire - to evaluate the relative importance of different causes of mortality. All seeds were eaten in controls and in both exclosure treatments within Gilbertiodendron forest in a matter of days. Seed survivorship to germination within exclosures in mixed species and fallow forest increased by approximately 10 and 25%, respectively, compared to Gilbertiodendron forest. Six-month seedling survivorship in controls was 37, 12, and 9% in Gilbertiodendron, mixed species and fallow forest, respectively. Seedling mortality was due to different causes in each forest type. In Gilbertiodendron forest controls, an equivalent percentage of seedlings died due to fungal and insect attack (27 and 28%, respectively), while in mixed species forest controls 28 and 55% of seedlings died of these causes, respectively. In fallow forest controls, 48% of seedlings died from predation and/or uprooting by small mammals, all in the first few weeks post-sowing; insect attack (26%) and drought (13%) were other important causes of seedling deaths. Protecting seedlings with exclosures had a dramatic effect on seedling survivorship within the fallow forest, increasing to over 50%. Because of their exceptional value, out or enrichment planting of these species may be economically viable both as part of forest management and agroforestry systems. Thus, planting out seedlings of these species in mixed species and fallow forest gaps with the appropriate soil chemical composition after the period of potential dry season and small mammal vulnerability is recommended.

The characters included zooidal characters and colony-level characters such as colony size and basal granule density. Species were classified by a series of multivariate cluster and linear discriminant analyses until the majority of specimens were assigned to their putative species with high confidence. In the first phase of the analyses, the colonies were grouped by ocean (Caribbean versus eastern Pacific), discriminated predominantly by colony size and basal granule density, characters that might reflect ecophenotypic responses to different conditions in primary productivity and predation between the two oceans. Further analyses of these two groups separately resulted in the discrimination of seven species. Five new species from the Caribbean (D. scutella, D. peltifera, D. bocasdeltoroensis, D. terminata and D. triangula), and two from the eastern Pacific (D. marcusorum and D. cookae). Of these, D. cookae had been identified previously as D. umbellata, a species once considered cosmopolitan, with a range spanning the Caribbean and eastern Pacific coasts of America. With the exception of one genetically defined clade represented by only two specimens, the correspondence of classification between groups discriminated morphometrically by separate step-wise multivariate analyses and those detected by a previous genetic analysis, ranged from 91% to 100%. In analyses of all specimens combined or separated by ocean, but using the total number of characters, 20% to 30% of the specimens could not be distinguished morphometrically from extremely similar sympatric species or cognate ("geminate") species from the opposite ocean. Diversity was higher in the Caribbean compared to the eastern Pacific, which reflects a similar pattern recently described for the genus Cupuladria from the same region.

A lighter-toned lower unit exhibiting phyllosilicates was deposited in a long-lived, quiescent distal alluvial or lacustrine setting. An overlying darker-toned and often blocky upper unit drapes the sequence and was emplaced during later high-magnitude flooding as an impounded Uzboi Vallis lake overtopped the crater rim. The stratigraphy provides the first geologic context for phyllosilicate deposition during persistent wet and perhaps habitable conditions on early Mars.

Consuming cured marine fish mitigates this deficiency. In Panama, trading cured fish from coastal to inland sites is documented ethnohistorically and can be inferred from the current archaeozoological record. Very large numbers of marine fish remains have been recovered at pre-Columbian sites located on and around Parita Bay, a mangrove-fringed estuary on the central Pacific coast. At Sitio Sierra, a farming village 12 km inland from the active marine shore, more than 70% of fish remains deposited between ca. 1800 and 1500 uncalibrated radiocarbon years BP proved to be of marine origin. Two small rock-shelters located downriver from Sitio Sierra and now 2.6 km from the marine shore (Vampiros-1 and Vampiros-2) show evidence for having been used intensively for fishing and preparing fish between ca. 2200 and 1900 BP. A prior model based on air photograph interpretation and sedimentological analyses of marine and terrigenous sediments suggest that these shelters would have been on or very near the active marine shore at this time. A much earlier occupation at Vampiros-1 dating to ca. 11,500-7700 BP corresponds to pre-agricultural (Paleoindian) and early agricultural (Early Preceramic) people who camped occasionally in this shelter when the transgressing ocean was in the process of flooding Parita Bay. No shell or bone was recovered in this earlier cultural component. In the more recent (2200-1900BP), component abundant remains of marine mollusks and crustaceans and vertebrate bones (mostly fish) are in excellent condition. A synopsis of the geological and cultural history of the Vampiros shelters is followed by preliminary observations on the relationship between pre-Columbian human activities and these sites' formation processes, soil chemistry, bone integrity and animal species. Evidence is accruing for human impacts on fish skeletons resulting from the in situ preparation of fish (i.e., gutting, cutting and smoking) providing the opportunity to compare our archaeofaunal data with the results of Irit Zohar's ethno-archeological research, which identified how preparing fish for salting and sun-drying at present-day Panamanian fishing villages around Parita Bay affects the fish skeleton physically and proportionally. There is a strong possibility that the Vampiros shelters were used to provision inland sites like Sitio Sierra with inshore marine fish although we cannot yet ascertain the means by which coastal foodstuffs may have arrived at the latter site.

Three species are recognized in the A. cristulifrons species complex. Alpheus cristulifrons sensu stricto is restricted to the western Atlantic, ranging from Florida and the Caribbean Sea to southern Brazil. The eastern Pacific A. cristulifrons sensu Kim & Abele, 1988 corresponds to A. utriensis Ramos & von Prahl, 1989, ranging from the Gulf of California to Colombia; this species can be separated from A. cristulifrons by the absence of balaeniceps setae on the male minor chela and the presence of bands on the antennular and antennal flagella. The eastern Atlantic A. cristulifrons sensu Crosnier & Forest, 1966 is described as A. xanthocarpus sp. nov. based on recently collected material from the island of Sao Tome in the Gulf of Guinea; this species differs from A. cristulifrons by the posteriorly more extending rostral carina and the presence of conspicuous yellow spots on the carpus and chela of the second pereiopod. Molecular data suggest that A. utriensis is the eastern Pacific sister clade to the amphi-Atlntic clade that includes A. cristulifrons and A. xanthocarpus sp. nov.

Quadridens AN - 20845791; 8228451 AB - Monstrilloid copepods from a series of zooplankton samples collected in the coastal area of Miami, Florida, were examined taxonomically. Several adult females were found to belong to an undescribed species of Cymbasoma within the C. rigidum species complex. It can be distinguished from its congeners by the body proportions, shape of head, cephalic ornamentation pattern, genital double somite with straight lateral margins, and structure of the fifth legs, which have a small, inner lobe arising from the distal 1/5 of segment. This species shows intraspecific variability in some characters (i.e. shape of head, cephalic and genital ornamentation patterns); hitherto, such variation has been reported only in another species of Cymbasoma. Our finding supports the idea of the nominal species C. rigidum comprising a taxonomic complex with several undescribed taxa. The other species recorded in the area was Cymbasoma quadridens Davis, 1947. This was first described from a single male specimen collected in 1947 in Biscayne Bay, Florida, and has not been recorded thereafter. The type specimen now being unusable, this species is redescribed herein based on another topotypic male specimen collected near the type locality. New data are added about the armature of its antennules and swimming legs, cuticular ornamentation, and structure of the genital complex.

The co-occurring HABs were investigated using in situ bioassays with additions of nitrogen (N) and phosphorus (P) alone and in combination to assess nutrient controls of these 'dueling' toxin-producing species. Photosynthetic, biomass (chlorophyll a), and (in L. majuscula) nitrogen fixation responses to nutrient enrichment were examined over 4 d. Primary productivity in Karenia spp. was consistently stimulated by N additions, while P additions failed to show stimulation. When added in combination with N, P did not lead to additional stimulation above N alone. Similar patterns of chlorophyll a stimulation were observed. These patterns were observed at 2 d, after which the cells fell out of suspension. Nutrient stimulation of L. majuscula metabolic activities as well as biomass production was smaller and much slower, relative to controls, than responses observed in Karenia spp. After the demise of Karenia spp., L. majuscula was able to continue utilizing subsequent nutrient additions, and it responded most strongly to the N+P additions after 4 d. This study confirms previous estuarine and coastal studies that indicated that when non-N sub(2)-fixing HABs co-occur with N sub(2)-fixing cyanobacterial HAB species, both N and P inputs need to be carefully considered and, in all likelihood, controlled.

In this study, we demonstrated that closely related crabs in the family Epialtidae coexist in the same algal environment but use alternative forms of camouflage--decoration and color change--to protect themselves from predation. Decoration and color change are both plastic camouflage strategies in that they can be changed to match different habitats: decoration occurs on a short timescale (hours to days), while color change accompanies molting and occurs on longer timescales (months). We found that the species that decorated the most had the lowest magnitude of color change (Pugettia richii); the species that decorated the least showed the highest magnitude of color change (Pugettia producta), and a third species (Mimulus foliatus) was intermediate in both decoration and color change, suggesting a negative correlation in utilization of these strategies. This negative correlation between color change and decoration camouflage utilization mirrored the effectiveness of these camouflage strategies in reducing predation in different species. Color camouflage primarily reduced predation on P. producta, while decoration camouflage (but not color camouflage) reduced predation on P. richii. These results indicate there might be among-species trade-offs in utilization and/or effectiveness of these two forms of plastic camouflage, with important consequences for distribution of these species among habitats and the evolution of different camouflage strategies in this group.

In demographic surveys, small juvenile corals are often grouped with larger and older corals or overlooked entirely due to their small size and cryptic nature. This study describes the distribution, abundance, and microhabitat of small juvenile corals, defined as post- settlement corals 31% of coral colonies in all habitats and depths, which resulted in positively skewed size-frequency distributions. The microhabitat of juvenile corals on coral rubble was best described as a convex surface covered with crustose coralline algae that lacked another coral within a 20 mm radius. This study provides basic ecology and natural history information of small juvenile corals and shows the feasibility of surveying corals <5 mm in diameter as a method for monitoring coral populations and assessing environmental changes on a coral reef.

However, selection for chemical deterrence might be strong among soft-sediment organisms that are sessile and expose at least part of their body above the surface. The phoronid Phoronopsis viridis is a tube-dwelling lophophorate that reaches high densities (26500 m super(-2)) on tidal flats in small bays in California, USA. We found that P. viridis is broadly unpalatable, and that this unpalatability is most apparent in the anterior section, including the lophophore, which is exposed to epibenthic predators as phoronids feed. Experimental removal of lophophores in the field increased the palatability of phoronids to predators; deterrence was regained after 12 d, when the lophophores had regenerated. Extracts of P. viridis deterred both fish and crab predators. Bioassay-guided fractionation suggested that the active compounds are relatively non-polar and volatile. Although we were unable to isolate the deterrent metabolite(s), we were able to rule out brominated phenols, a group of compounds commonly reported from infaunal organisms. One predator, juvenile Scorpaenichthys marmoratus, consumed all P. viridis extracts and whole P. viridis. However, over time, this predator rejected phoronids when fed a diet that included 2 to 3 phoronids d super(-1). The broadly effective defenses possessed by phoronids, which may be unusual among soft-sediment invertebrates, may play a key role in allowing them to reach high densities.

This area was inhabited by a dense population of the burrowing crustacean Upogebia deltaura, with a rich infaunal community, high in abundance and diversity throughout the study period. A total of 7297 individuals comprising 126 taxa were obtained from the 52 samples (four replicates on each occasion). A total of 64 polychaete taxa were found, followed by 22 molluscs, 21 crustaceans, 7 echinoderms, and 12 species not belonging to any of these taxonomical groups (varia). Molluscs dominated in abundance throughout the study period except in November 1980, January 1981, and March 1981, when polychaetes dominated. Species abundance varied seasonally. The multivariate analyses of abundance data also demonstrated a limited temporal change, less pronounced during winter months. Bottom water salinity was negatively correlated to the number of taxa. Bottom water temperature was negatively correlated to polychaete abundance, and positively correlated to mollusc abundance. Upogebia deltaura correlated positively with four taxa: Nereimyra sp., Spisula subtruncata, one species within the family Talitridae, and Mya truncata, and negatively to Scoloplos armiger.

This is partly due to the irregular occurrence of driving phenomena such as gelatinous plankton pulses in this realm. Gelatinous plankters rely on their life cycles and histories to exploit temporarily abundant resources with an undeniable, but often overlooked, impact on marine food webs. Dramatic increases of gelatinous filter-feeders and/or carnivores (both native and nonindigenous species) are frequently observed, and explanations of these blooms alternatively invoke ecosystem variability, climate change, unspecified anthropogenic perturbation or removal of top predators from trophic networks. Gelatinous plankters, however, are not anomalies in plankton dynamics: the recognition of the ecological importance of their pulses, based on their life cycle patterns (often involving benthic stages), is a critical breakthrough to understand the cycling diversity of plankton in space and time. The current study focuses on the many neglected aspects of the ecology and biology of gelatinous zooplankton, describes how life cycle patterns are central in marine ecology, as are the pulses of gelatinous organisms, and highlights how such a dramatic lack of knowledge can affect our understanding of the marine ecosystem as a whole.

During their early life stage, juvenile green turtles in the southwestern Pacific inhabit the pelagic zone where they feed omnivorously on neustonic material. At approximately 44 cm curved carapace length they recruit to inshore foraging habitats where they become primarily herbivorous. In this study we investigate the change in stable isotope (d super(13)C and d super(15)N) composition of green turtle epidermal tissue throughout their life history to examine this ontogenetic shift in diet and habitat as it occurs in a southwestern Pacific green turtle population. Turtles that had recently recruited to foraging grounds in Moreton Bay, Australia had significantly higher d super(15)N isotopic signatures when compared with all other life history groups examined and significantly lower d super(13)C when compared with all age classes other than pelagic juveniles. Adult and large immature turtles had similar isotopic signatures and were both significantly enriched in super(13)C when compared with hatchlings and small immature turtles. These results support previous observations that suggest pelagic juveniles are foraging in a different habitat and at a higher trophic level than turtles captured in the neritic environment. This is the first study to capture the entire life history of green turtles in terms of foraging ecology and supports the ontogenetic shift previously observed in traditional diet and behavioral studies of green turtles.

Research has shown that the Hg methylation reaction is dependent on the availability of SO sub(4) (as an electron acceptor) because SO sub(4)-reducing bacteria (SRB) mediate the biotic methylation of Hg. Much less research has investigated the possible organic C limitations to Hg methylation (i.e. from the perspective of the electron donor). Although peatlands are long-term stores of organic C, the C derived from peatland vegetation is of questionable microbial lability. This research investigated how both SO sub(4) and organic C control net MeHg production using a controlled factorial addition design in 44 in situ peatland mesocosms. Two levels of SO sub(4) addition and energetic-equivalent additions (i.e. same number of electrons) of a number of organic C sources were used including glucose, acetate, lactate, coniferous litter leachate, and deciduous litter leachate. This study supports previous research demonstrating the stimulation of MeHg production from SO sub(4) input alone (6200 pg/L/day). None of the additions of organic C alone resulted in significant MeHg production. The combined addition of SO sub(4) and some organic C sources resulted in considerably more MeHg production (6500 pg/L/day) than did the addition of SO sub(4) alone, demonstrating that the highest levels of MeHg production can be expected only where fluxes of both SO sub(4) and organic C are delivered concurrently. When compared to a number of pore water samples taken from two nearby peatlands, MeHg concentrations resulting from the combined addition of SO sub(4) and organic C in this study were similar to MeHg "hot spots" found near the upland-peatland interface. The formation of MeHg "hot spots" at the upland- peatland interface may be dependent on concurrent inputs of SO sub(4) and organic C in runoff from the adjacent upland hillslopes.

Focus is on the stratigraphy, petrology, and faunal assemblages of radiocarbon-dated core sections recovered at major ruins at the site. The late Holocene development of this margin surface is unusual in that it has been subject to important geologically recent uplift since the city's founding, in contrast to predominant subsidence and relative sea-level rise that characterize most of the delta margin west of Pelusium. Vertical tectonics resulted from displacement along the Pelusiac Line, a major structural feature several kilometers south of Pelusium. The geoarchaeological survey shows the was built with ready access to the Mediterranean, after tectonic uplift, from similar to 1000 to 800 BC. It was then, when Egypt was subject to Assyrian control, that the margin evolved from an open shallow marine (prodelta, delta-front) setting to a coastal one. The city's progressive decline was influenced by warfare with Persians and other invaders from the east, effects of plague, and diminished role of its commercial and trade activities following construction of Alexandria by the Greeks. However, Pelusium's eventual demise also resulted from natural factors, especially tectonically controlled motion of the lower delta plain. Vertical shifts around 800-850 AD and subsequent periods resulted in rapid coastal build-out north of Pelusium. This caused a cutoff of the city from the sea and the Nile's Pelusiac branch, the major navigational byway into the delta. Pelusium, after approximately 800-850 AD, continued as a commercial center for an additional three to four centuries prior to its abandonment by the time of the Crusades. Submergence of the city on the delta margin by rise of relative sea level has been effectively counteracted by episodic fault-related uplift of this lower plain sector and continued subaerial exposure since Byzantine time.

In a recently published and particularly promising test case, an evolutionary time series of populations displaying armor reduction in a fossil stickleback lineage could not be consistently distinguished from a null model of neutral drift, despite excellent temporal resolution and an abundance of indirect evidence implicating natural selection. Here, we revisit this case study, applying analyses that differ from standard approaches in that: (1) we do not treat genetic drift as a null model, and instead assess neutral and adaptive explanations on equal footing using the Akaike Information Criterion; and (2) rather than constant directional selection, the adaptive scenario we consider is that of a population ascending a peak on the adaptive landscape, modeled as an Orstein-Uhlenbeck process. For all three skeletal features measured in the stickleback lineage, the adaptive model decisively outperforms neutral evolution, supporting a role for natural selection in the evolution of these traits. These results demonstrate that, at least under favorable circumstances, it is possible to infer in fossil lineages the relationship between evolutionary change and features of the adaptive landscape.

Forests or woodlands prevailed at mid-latitudes in North America during the early Eocene but tree spacing and canopy structure are uncertain. Here we use stable carbon isotope values ( delta 13C ) in early Eocene mammalian faunas to infer canopy structure. We compare delta 13C values in two diverse fossil assemblages from the central Bighorn Basin to values predicted for mammals in a variety of open and closed habitats, based on modern floras and faunas. We conclude that these early Eocene faunas occupied an open canopy forest. We also use carbon and oxygen isotopes to infer diet and microhabitat. Three higher level taxa have significantly different mean delta 13C values, and values are negatively correlated with body mass. The pattern suggests diets high in leaves for larger mammals, and fruit or other non-foliar plant organs for small ones. A preference in the larger mammals for wetter habitats with high water availability to plants may also have contributed to the pattern.

Primary productivity was measured in 12 h time-course experiments using enclosures that transmitted either full-spectrum solar UVR or only long-wavelength UVA. Recovery from inhibition was determined by transferring samples from high to low UVR at intervals during the incubation. Biological weighting functions for UVR inhibition of photosynthesis were also determined for each experiment. Photosynthesis measurements were compared to model predictions using 3 exposure-response relationships: an irradiance-based (E) model that assumes rapid repair, a cumulative-exposure (H) model that assumes no repair, and a model that incorporated slow repair (R model). Open-ocean phytoplankton were generally much more sensitive to UVR inhibition than coastal assemblages, which primarily had high rates of repair (E model). In contrast, open-ocean assemblages generally recovered from inhibition more slowly (R model). Some recovery was evident in all cases, so the H model was not applied to any assemblage. Our previous view of repair being either simply present or absent is therefore revised to recognize that repair rates range from slow to fast and should be taken into account, together with spectral weight, in assessments of photosynthetic response to UVR in the Southern Ocean, including the effect of ozone depletion. Information on repair rate is particularly important for simulations of production in vertically mixed surface layers.

Here, we investigated the common salt marsh amphipod Gammarus palustris, which is a habitat specialist that feeds specifically on the dead leaves of its living host plant, salt marsh cordgrass Spartina alterniflora. Restricted use and consumption of dead S. alterniflora was reinforced by superior amphipod performance (survival, size, and sexual development) on dead S. alterniflora relative to other diets, and was driven at least in part by amphipods being physically able to feed on soft, decaying plant tissues but not live, turgid tissues. Stable isotopes from field surveys and laboratory assimilation assays suggest that amphipods also feed on S. alterniflora in the field, and that the important marsh fish Fundulus hetroclitus feeds on amphipods. Thus, consumption of G. palustris by F. heteroclitus may be an important trophic pathway linking cordgrass production to nearshore food webs. Importantly, direct isotopic analyses of amphipods and their known food sources demonstrated substantial deviation of observed fractionation factors from idealized standards. This suggests caution when using idealized trophic shifts to describe food web linkages, and a renewed focus on assimilation assays to determine the realized fractionation of dietary isotopes.

Hypoxia is an important stressor in aquatic ecosystems that usually decreases abundance and biomass of benthic fauna. In field surveys, predator abundance is low in hypoxic areas, and in lab experiments, predators reduce their feeding rates under hypoxic conditions, leading to the hypothesis that consumer stress models (CSMs), rather than prey stress models (PSMs), apply to the systems. We tested predictions from these models with manipulative field experiments wherein we varied predator access to marked Macoma balthica clams at deep and shallow sites in the York River, Chesapeake Bay, before (June) and during (August) hypoxic episodes. In June, dissolved oxygen in deep and shallow sites was normoxic (>2 mg l super(-1)) for most of the experiment. In August, the shallow zone remained normoxic, while the deep zone experienced several hypoxic episodes. During hypoxia, predation rates in hypoxic sites were more than twice those in normoxic sites, whereas mortality due to physical stress did not differ between time periods or depths. Ambient clam densities were lower at the deep sites than at the shallow sites, and in August than in June. We conclude that hypoxia increased the susceptibility of benthic prey to predation, enhancing infaunal secondary production available to predators, but concurrently reducing the resilience of the benthic community. These findings are inconsistent with the predictions of CSMs, indicating that PSMs better describe this system.

The Hofergraben Member consists mainly of silty-sandy marls of wave-dominated, low-energy shore zone to shallow neritic environments. Substrates of soft to firm mud supported level-bottoms of non-rudist bivalves, gastropods, solitary corals, colonial corals, rudists, echinoids, and benthic foraminifera. Boring and/or encrustation of fossils overall are scarce. In the marls, Cunnolites is common to abundant. Both a cupolate shape and a lightweight construction of the skeleton aided the coral to keep afloat soft substrata. Cunnolites taphocoenoses are strongly dominated by small specimens (about 1-3 cm in diameter). Cunnolites was immobile and mostly died early in life upon, either, smothering during high-energy events, rapid sedimentation associated with river plumes, or by toppling and burial induced by burrowing. Comparatively few large survivor specimens may show overgrowth margins interpreted as records of partial mortality from episodic sedimentation or tilting on unstable substrate. Scattered pits and scalloped surfaces on large Cunnolites may have been produced, in some cases at least, by predators (durophagous fish?). Post-mortem, large Cunnolites provided benthic islands to corals, epifaunal bivalves and bryozoans. In a single documented case of probable in vivo contact of Cunnolites with the colonial coral Actinastraea, the latter prevailed.

It is indicated that the cheetahs are easily domesticated and long revered. It is mentioned that the failure of captive breeding means that cheetah fanciers have to replenish their supply with wild ones. The results indicate that the examination of semen under microscope reveals low sperm counts, about 10 percent of the norm for other felines. Also, there are huge numbers of malformed sperm about 70 percent in each sample. It is known that the cheetah will not be a robust, vigorous species anytime in the foreseeable future and that saving the animal requires a combination of strategies.

Here we use plant fossils from the Bighorn Basin of Wyoming to document the combined effects of temperature and rho CO (sub 2) on insect herbivory. We examined 5,062 fossil leaves from five sites positioned before, during, and after the PETM (59-55.2 Ma). The amount and diversity of insect damage on angiosperm leaves, as well as the relative abundance of specialized damage, correlate with rising and falling temperature. All reach distinct maxima during the PETM, and every PETM plant species is extensively damaged and colonized by specialized herbivores. Our study suggests that increased insect herbivory is likely to be a net long-term effect of anthropogenic rho CO (sub 2) increase and warming temperatures.

These fine-grained mantling layers are of interest for their association with early mare volcanic processes, and as possible sources of volatiles and other species for lunar outposts. We present Earth-based radar images, at 12.6 and 70 cm wavelengths, of the pyroclastic deposit that blankets the Aristarchus Plateau. The 70 cm data reveal the outlines of a lava-flow complex that covers a significant portion of the plateau and appears to have formed by spillover of magma from the large sinuous rille Vallis Schroteri. The pyroclastics mantling these flows are heavily contaminated with rocks 10 cm and larger in diameter. The 12.6 cm data confirm that other areas are mantled by 20 m or less of material, and that there are numerous patches of 2 cm and larger rocks associated with ejecta from Aristarchus crater. Some of the radar-detected rocky debris is within the mantling material and is not evident in visible-wavelength images. The radar data identify thick, rock-poor areas of the pyroclastic deposit best suited for resource exploitation.

To understand the natural patterns of spatial differences, polyclad assemblages were sampled in seven coastal regions across the wider Caribbean spanning 15 degree latitude and 24 degree longitude between May and June 2005 and May and September 2006. In total, 67 species in 28 genera and 17 families were recorded from 62 sites. Only two species were found in all surveyed regions, Melloplana ferruginea and Pseudoceros bicolor. Conversely, 41 species were restricted to one or two sites, and 34 species were represented by one or two individuals. The distribution and abundance of species varied between the two suborders. Cotyleans were most species rich and had a higher number of species of restricted range, while Acotylea showed a higher proportion of rare species; however, two species were highly abundant comprising over half of the individuals counted. In most habitats, polyclads were rare, but in some intertidal habitats two species, Styloplanocera fasciata and Boninia divae were densely aggregated and dominant members of the benthic epifauna. Alpha diversity was variable but showed no evidence of a relationship with latitude, longitude or depth. Beta diversity increased with the number of habitats sampled and was highest for cotyleans. Highest gamma diversity was recorded in Jamaica and the US Virgin Islands and was not significantly correlated to alpha diversity. Overall assemblages from the seven regions were similar, revealing faunal homogeneity across the wider region. Reef assemblages were distinct from other habitats dominated by species of the Cotylea. Reefs from Panama and the US Virgin Islands were the most species rich.

SP., A NEW HERMAPHRODITIC SHRIMP FROM THE SOUTHWESTERN CARIBBEAN SEA (CARIDEA: HIPPOLYTIDAE). AN - 19400650; 8694444 AB - Lysmata hochi n. sp., a new peppermint shrimp, is described from Bocas del Toro, Caribbean coast of Panama. All individuals were collected on near-shore fossil coral terraces with deep channels and caves, sparsely covered with seagrass. Besides the type locality, L. hochi n. sp. also occurs in Cahuita, Costa Rica, in a similar type of habitat. The new species can be distinguished from other species of Lysmata by the presence of an unguis-shaped accessory branch on the lateral antennular flagellum; the rostrum with three dorsal teeth, followed by two mid-dorsal teeth on the carapace posterior to the orbital margin; the number of carpal segments of the second pereiopod ranging from 21 to 24; the presence of two to four ventrolateral spines on the merus of the third pereiopod; the dactylus of the third to fifth pereiopod bearing two spines in addition to a bifurcated inguis; and the conspicuous color pattern, especially the irregular bright red bands on the pleon. Based on morphology and (where known) color patterns, L. hochi n. sp. appears to be most closely related to the Indo-West Pacific L. kuekenthali (De Man) and the eastern Atlantic L. uncicornis Holthuis and Maurin. Anatomical observations, field population studies and laboratory experiments indicate that L. hochi n. sp. is a protandric simultaneous hermaphrodite, with a primary male phase followed by a simultaneous hermaphrodite phase.

Rotenone, a natural substance traditionally used by subsistence fishers, is a uniquely efficient tool for sampling reef and other shore fishes for marine research. Unfortunately, such sampling is perceived as being highly destructive, and increasing prohibitions against using rotenone in many countries will soon cripple essential research on reef-fish biodiversity worldwide. In this article we dispel common misconceptions about the environmental effects of small-scale rotenone sampling in marine research.

AN - 19312812; 8590501 AB - Successful use of hatchery-reared juveniles to enhance recruitment-limited populations or severely depleted stocks is contingent upon their ability to survive and grow upon release into the wild. Hatchery conditions often result in juveniles that exhibit morphological, physiological, or behavioral characteristics different from their wild counterparts. Managers of stock enhancement or restocking programs need to assess whether any such deficiencies translate into differences in performance between hatchery-reared and wild juveniles in the field. If so, the deficits may be minimized through conditioning strategies. In this review, we summarize various aspects of the morphology and behavior of cultured and wild blue crabs, Callinectes sapidus, and compare our work on these crabs to studies on other invertebrates. We identify similarities and differences between cultured blue crabs and wild conspecifics. In some cases where differences existed, conditioning of the hatchery-reared crabs before release rapidly mitigated the defects, and, overall, any remaining differences did not translate into decreased survival. We conclude that there are no significant impediments to the fitness of hatchery-reared blue crabs used in release programs.

A key, but often overlooked, consideration for optimizing release strategies is the interaction of factors (e.g., release season, release size, stocking density, release habitat, etc.). Here, we summarize seasonal and size-dependent patterns of survival and growth for juvenile blue crabs using long-term field tethering and experimental releases of hatchery-reared cohorts within the Rhode and South Rivers, Maryland, USA, and review the direct and interactive effects of these factors. Survival of both tethered and free-ranging hatchery-reared juvenile crabs was high in early spring and fall and lowest in summer. Survival was largely independent of size during spring and fall, but increased with size in summer, indicating that optimal size at release varies seasonally. Hatchery-reared juveniles from spring releases grew rapidly, matured during their first season, and migrated to the spawning sanctuary in the fall of their first year. While release season and size each had direct effects on enhancement success, the results also highlight the important interaction between release season and size on enhancement success using the blue crab in Chesapeake Bay as a model.

In addition, only a small portion (11-22%) of the spawning stock migrates successfully to the historic spawning areas of the lower estuary. As a result, recent management goals to decrease harvests and increase spawning stock biomass have been adopted by the different Chesapeake Bay regulatory agencies. The crisis has also prompted an experimental assessment of the potential for stock enhancement to increase the number of spawners. While much of the current stock enhancement work has focused on assessing the competency of hatchery-reared individuals and identifying key processes that optimize survival and growth of juveniles to maturity, less attention has been paid to examining factors that influence the long-term efficacy of stock enhancement efforts. Here we discuss important interactions between blue crab life history, stock enhancement efforts, and management options available to increase the standing stock of mature females in Chesapeake Bay. We propose the establishment of migration corridors to protect female blue crabs when they undergo the long-distance migration after mating to lower Bay spawning areas.

However, crab stock enhancement research to date has focused primarily on hatchery production, with only limited field assessments of the efficacy of releases to increase the target population. This paper summarizes ongoing research to develop effective release strategies for hatchery-reared juveniles to augment the spawning biomass of Chesapeake Bay blue crabs, which has declined > 80% in 15 years and appears to be recruitment limited. Our release experiments focused on three factors: (1) components of preparation and release, which included life stage and size at release, pre-release conditioning to minimize differences between hatchery and wild crabs, and micro-habitat and micro-timing of release; (2) stocking variables, particularly seasonal timing of release and stocking density; and (3) site selection and coordination, including release macro-habitat and location of release sites along environmental gradients, emphasizing coordination of release site and fishing pressure with migration corridors linking nurseries to spawning areas. In the first 5 years of research, we demonstrated that small (1,000-10,000) cohorts of hatchery reared, 20 mm, 7th-instar juvenile blue crabs can be tagged and released into small (1-10 ha) coves, and that these cohorts can be followed successfully to quantify growth, survivorship, and productivity of the enhanced population. We also determined the timing and routes of migration using a tag-reward system with the cooperation of fishers. Our multifaceted research strategy provides a model for responsible approaches to stock enhancement of other species with complex migratory life cycles.

It is noted that the last fluent speaker of Mahican died in 1933, & the Mahicans have often been confused with the Mohegans of eastern Connecticut & the fictional Mohicans of James Fenimore Cooper's novels.

A new species, H. atlanticus nov. sp., is proposed for the tests with one or rarely two last-formed chambers that are strongly radially elongate and distally tapering in the final whorl. Hastigerinoides consists of three phylogenetically related species: H. clavata (Bronnimann, 1952), H. atlanticus nov. sp., and H. alexanderi (Cushman, 1931). This genus evolved from Globigerinelloides escheri, a Coniacian-middle Campanian, globular- to suglobular-chambered species.

These are subdivided into meteorite groups, the basic unit of meteorite classification. Although no formal guideline is in place for the minimum number of meteorites needed to define a group, common practice is that there should be five or more members in a group. A defined meteorite group is thought to be derived from a single asteroid. However, some groups are genetically related and are derived from a common parent asteroid. Chondrites are primitive stony meteorites; rocks whose compositions are little changed since their formation in the solar nebula. There are fourteen defined groups of chondrites, and they make up the vast majority of meteorites falling to Earth in the current epoch. Achondrites are stony meteorites of two broad types. Some are primitive materials like chondrites, but most are the products of igneous differentiation. There are ten defined groups of achondrites, of which seven are differentiated types. Irons are also the products of asteroidal differentiation, having crystallized from metallic melts separated from chondritic precursors. There are thirteen defined groups of iron meteorites. Stony-irons are also differentiated materials, and both the rocky and metallic phases were formed by igneous processes on asteroids. There are two defined groups of stony-iron meteorites. In addition to those that fit into groups, there are many meteorites that are unique, or for which there are less than five examples. These ungrouped meteorites make up a substantial fraction of meteorites recovered to date.

Petrographic, mineralogic, oxygen and short-lived isotope systematics ( (super 26) Al- (super 26) Mg, (super 53) Mn- (super 53) Cr, (super 129) I- (super 129) Xe) suggest that alteration occurred in the presence of aqueous solutions under variable physico-chemical conditions (temperature, water:rock ratio, pH, f (sub O2) , and fluid compositions) in an asteroidal setting; it started within 1-2 m.y. after formation of the CV CAIs, was multistage, and lasted up to 15 m.y. (Krot et al. 2006 and references therein). Here we review bulk O-isotopic compositions of chondritic materials, O-isotopic compositions of secondary minerals produced during asteroidal alteration, and possible effects of fluid-assisted thermal metamorphism on O-isotopic exchange in primary, high-temperature minerals (melilite and anorthite) in the CV and CO CAIs. The implications of these data for understanding temperatures of alteration, water:rock ratios, and oxygen isotopic composition of water, that probably accreted into chondrite parent bodies in the form of ice, are discussed. The inferred or measured O-isotopic composition of the meteoritic water is close to the terrestrial fractionation line (Delta (super 17) O = + or -2 per mil); it is very different from the inferred O-isotopic compositions of the Sun [Delta (super 17) O approximately -25 per mil] (Clayton 2002; Yurimoto and Kuramoto 2004; Hashizume and Chaussidon 2005; Lyons and Young 2005), suggesting significant evolution of O-isotopic composition of the gaseous reservoir in the inner protoplanetary disk over its short (approximately 3-5 m.y.) life time.

In the case of the differentiated meteorite parent bodies, the redox conditions range over at least six orders of magnitude (from approximately 5 log units below the Iron-Wustite buffer to slightly above it) and are determined in large part by the compositions of the undifferentiated precursor materials that accreted to form these parent bodies. Lunar basalts record oxygen fugacities ranging from close to the Iron-Wustite (IW) buffer to approximately 2 log units below it. The current best estimate of the oxygen fugacity of the lunar mantle is approximately 1 log unit below IW. Martian crustal rocks represented by the Shergottite-Nakhlite-Chassignite group of meteorites record a wide range of oxygen fugacities. The basaltic shergottites range from slightly below the IW buffer to approximately 2 log units above it, whereas the cumulate nakhlites (and chassignites) are relatively oxidized (approximately 3-4 log units above the IW buffer). Following early metal-silicate and crust-mantle differentiation on Mars, the depleted martian mantle is likely to have been reduced (close to the IW buffer or slightly lower). Metasomatism and secondary (hydrous) alteration are likely to have produced silicate reservoirs on Mars that are relatively more oxidized (most likely > or =3 log units above the IW buffer). The redox conditions on the other terrestrial planets (Mercury and Venus) are not well constrained. Based on the limited information from remote spacecraft and telescopic observations of surface rocks on these planets, it is inferred that silicate reservoirs on Mercury are highly reduced; those on Venus are likely to be somewhat more oxidized than on Mercury, possibly similar to the lower mantle of Earth.

While the chemical evolution of the Galaxy has progressed since then, processes in the interstellar medium (ISM) that involve oxygen are relevant to the origins of oxygen in the Solar System. Oxygen in the ISM can be found as neutral or ionized atomic gas and as a constituent of molecular gas, volatile ices, and refractory minerals in dust, with the dominant state depending on the specific environment. The gas-phase abundance of atomic oxygen is well-known in the diffuse ISM that fills most of the Galaxy"s volume, but the state of oxygen in denser environments is poorly understood. The ISM abundances of isotopes of oxygen other than 16O cannot be easily determined due to observational constraints. Oxygen in interstellar dust is primarily found in the form of silicates that are created in evolved stars and then ejected into the ISM before being incorporated into the formation of new solar systems. Some of the important unknowns concerning oxygen in the ISM include the "cosmic" (i.e., total) abundance of oxygen, the abundance of oxygen in dust, and the details of dust grain processing in the ISM.

Storage of most comets in the cold, outer regions of the Solar System since their formation has probably helped minimize any subsequent parent body processing of their contents. As a result, cometary materials may represent samples that best preserve the original components from which our Solar System was made. Comparison of cometary and asteroidal materials (which formed much closer to the Sun) can also provide insights into large-scale heterogeneity and transport of materials in the early solar nebula. Comets are also of considerable interest since they may have delivered volatiles, like H (sub 2) O, to the early cooling Earth, thereby playing a key role in making the Earth habitable. Comets should also have delivered organic materials to the surface of the early Earth and these, depending on their nature, may have played a role in the origin of life. Thus, the study of the composition of comets has the potential to provide important insights into the formation and evolution of our Solar System (and by extension, other planetary systems), and the creation of an inhabited Earth. The study of the chemistry, mineralogy, and isotopic distributions of oxygen in cometary materials can provide unique information that addresses these issues. Our current knowledge of the nature of oxygen in comets is based on several different lines of evidence, including remote telescopic and spacecraft observations of comets, direct laboratory analyses of extraterrestrial samples, and in situ measurements of a small number of individual comets. Information derived from these different approaches suggests that the chemical, mineralogical, and isotopic state of oxygen in these primitive bodies is extremely variable, i.e., comets appear to be made up of a wide range of very different components that are considerably out of equilibrium with each other. This is consistent with the idea that cometary materials should have largely escaped extensive parent body processing. The study of samples recently returned from Comet 81P/Wild 2 by the Stardust spacecraft has immensely improved our understanding of cometary materials. Of particular interest is the observation that these samples contain intimate mixtures of both volatile and refractory oxygen-bearing materials. This suggests that while comets formed in the outer reaches of the protosolar disk, they were constructed of materials that had originally formed and evolved in a wide variety of locations that spanned essentially the entire radial extent of the protosolar nebula.

C. Urey and colleagues in 1934, but appropriate instrumentation had not yet been developed. The modern era of oxygen isotope cosmochemistry began with the study of Apollo lunar samples in 1969 and of Allende refractory inclusions in 1973. The large (>5%) variations in (super 17) O/ (super 16) O and (super 18) O/ (super 16) O ratios, and small variations in (super 17) O/ (super 18) O were first interpreted as nucleosynthetic effects, but are now recognized to be the result of chemical processes early in Solar System history. Thus oxygen isotopes provide natural tracers for processes of formation of solid bodies in the inner Solar System. In particular, oxygen isotopes are very useful in recognizing genetic associations among meteorite groups. They also have been valuable in the study of parent body processes, such as metamorphism and aqueous alteration. There is conjecture that the ultimate cause of the oxygen isotope effects may be isotope-selective photodissociation of CO, which will be tested by isotopic measurement of solar oxygen and nitrogen collected in the NASA Genesis mission.

This chapter attempts to collate the huge data set of oxygen isotopic measurements of asteroidal material, as sampled by meteorites, in order to understand some of the processes involved in the formation of these primitive bodies and how such events have affected the oxygen isotopic ratios, ultimately offering a window back to the very origin of Solar System and its primordial oxygen isotopic heterogeneity. Oxygen is generally a major element in the gas, liquid and solid phases that have interacted throughout the evolution of the Solar System, its chemical properties ensuring that there is abundant opportunity for reactions and exchange, the details of which can be recorded in the isotopic ratios of the products. Such processes can be crudely subdivided into the following six categories: Early solar nebular isotopic heterogeneity High-temperature modification of nebular components Metamorphism and melting in asteroids Aqueous alteration in asteroids Mixing of components/brecciation Terrestrial weathering It is clear from the isotopic variation in the earliest-formed nebular components, such as refractory inclusions and chondrules, that there was considerable oxygen isotopic heterogeneity in the early solar nebula, spanning over 50 per mil, and perhaps much greater, in both delta (super 17) O and delta (super 18) O. The origin of this variation is discussed elsewhere in this volume. However, isotopic exchange between the (super 16) O-rich solids and (super 17) O- and (super 18) O-rich gas phase(s) resulted in a wide range of isotopic variation in these early-formed components, offering insight into the conditions of these processes and the evolution of the reservoirs with time and/or space. Once accreted onto the early planetisemals, much of the primitive nebular components experienced considerable modification. The metamorphism and melting experienced by some of these bodies, most probably the result of heating from the decay of short-lived radionuclides (e.g., (super 26) Al), resulted in progressive homogenization, within individual bodies, of any original isotopic heterogeneity. Complete homogenization appears to have been achieved in the HED parent body, indicating very high levels of melting and the development of a large magma ocean. The carbonaceous and ordinary chondrite parent bodies experienced more modest heating, sufficient to mobilize water ice that accreted along with the more refractory materials. The subsequent reactions between the liquid and solid phases at low temperature imparted large isotopic fractionations which record some of the conditions of this alteration, such as water:rock ratio, temperature, and isotopic signature, and thus potentially the origin of the water ice. The evolution of the asteroidal bodies has been far from simple, and an important use of oxygen isotope measurements has been in the identification of the components present in some meteorites, the result of breakup, reassembly and mixing of different bodies during impact processing. The final oxygen isotopic signatures imparted into meteorite samples are those associated with terrestrial weathering. The isotopic compositions of the weathering products depend on location (primarily latitude) while the magnitude of the weathering is dependent on many factors, with some meteorites (e.g., highly reduced enstatite chondrites and the matrix-rich CO3s) particularly susceptible to such effects.

We begin by assessing the galactic evolution model for oxygen isotope variation in the Solar System in order to compare the predictions of a leading nucleosynthetic model with those of the chemical models. There are two fundamentally different classes of possible chemical mechanisms for mass-independent oxygen isotope fractionation in the early Solar System. One is symmetry-induced intramolecular vibrational disequilibrium of vibrationally excited reactant oxygen-bearing molecules. The other is isotope selective photodissociation of CO coupled with self-shielding and formation of H (sub 2) O. Symmetry-induced fractionation is an experimentally verified process with solid theoretical foundations. It is observed to occur in Earth's atmosphere. It could have resulted in preservation of oxygen MIF effects only if mediated by dust grain surfaces. CO self-shielding is an attractive hypothesis for the origin of mass-independent oxygen isotope fractionation in the early Solar System because it appeals to a process that apparently occurs in the interstellar medium, but it lacks experimental verification. Three astrophysical settings for CO self-shielding are proposed as sites for generating Delta (super 17) O variability in the early Solar System. One is the inner annulus of the protostellar disk at relatively high temperature. Another is the surface of the disk high above the midplane where light from the central star grazes the gas and dust of the disk, resulting in a zone of active CO predissociation and self-shielding. Interstellar light illuminating the disk at high incident angles causes a similar horizon of CO photodestruction. Variations in (super 16) O could also have been inherited from self-shielding by CO in the molecular cloud that gave rise to the protosun. The overall consequence of CO self-shielding is conversion of CO gas to (super 16) O-poor H (sub 2) O. A key difference between galactic evolution, chemically-induced MIF effects, and CO self-shielding is the predicted relative oxygen isotopic compositions of primeval dust and the Sun. Therefore, the oxygen isotopic composition of the Sun will be a crucial arbiter that may permit us to narrow the list of possible origins for oxygen MIF in the early Solar System.

The dynamic interactions between Earth's lithosphere, hydrosphere, biosphere and atmosphere are elucidated by a wealth of oxygen isotope data, that in turn provide a template for predicting the types of variations that occur on other planets. These isotopic variations are basically controlled by two master effects. First, isotopic fractionations among coexisting phases tend to be greatest at low temperatures, and are also large when they involve interactions between solids or liquids and gaseous phases. Second, material balance effects require the (super 18) O contents of the most abundant phases to be close to the planetary average, and restrict extreme isotopic enrichments or depletions to minor phases. These dual controls of fractionation and material balance work in concert with practically any other dynamic process to foster the upward enrichment and increased heterogeneity of (super 18) O contents on Earth, and, by implication, in planetary lithospheres in general. Upward (super 18) O enrichment in planetary lithospheres is promoted by the tendency for the least dense silicate and oxide minerals to concentrate (super 18) O relative to more dense minerals, and also by convective transfer, fractional crystallization, hydrothermal alteration, and other processes. Earth's continents and the uppermost parts of its ocean floor consequently have higher (super 18) O contents than average upper mantle material, and normal sediments, carbon dioxide and oxygen gas are all very rich in (super 18) O. Heterogeneity is evident in the large ranges of delta (super 18) O values observed in sediments (at least +8 to +38 per mil) and terrestrial igneous rocks (at least -10.5 to +16 per mil), and in the even larger ranges in natural waters and atmospheric gases, all representing materials that constitute, or interacted with, oxygen reservoirs near Earth's surface. Key identified processes include weathering, precipitation from water, phase changes, exchange with infiltrating hydrothermal fluids, and assimilation of wallrocks having disparate compositions. All such processes that promote the upward enrichment and heterogeneity of (super 18) O complicate the deduction of the bulk planetary contents of this isotope.

Application of the results to the compositions of coexisting Ti (super 3+) -bearing fassaitic clinopyroxene+melilite pairs in natural inclusions shows that, if they crystallized at approximately 1509 K, they did so at log f (sub O2) = -19.8 + or - 0.9, only slightly below the equilibrium log f (sub O2) of a partially condensed system of solar composition at the same temperature, -18.1 (sub -0.3) (super +0.2) , or IW-6.8. Fassaite is the only f (sub O (sub 2) ) indicator that shows that anything in chondrites formed in a system that was close to solar in composition. Solar composition is so reducing that equilibrium calculations predict vanishingly small FeO/(FeO+MgO) ratios in the condensate until temperatures fall below 800 K, where significant oxidation of metallic iron and formation of fayalite in solid solution with previously condensed forsterite begin. The mechanism for the latter process is diffusion of Fe (super 2+) through forsterite, but the diffusion rate is nearly zero at these temperatures. By comparison to what is achievable in a system of solar composition, the mean FeO/(FeO+MgO) ratio of the olivine in chondrules in unequilibrated ordinary chondrites (UOCs) is very high, approximately 0.15. Making such ratios in chondrule precursors by solar nebular processes requires sufficiently high f (sub O2) for iron to become oxidized above temperatures where diffusion of Fe (super 2+) becomes very slow. Two dynamic models for enrichment of oxygen relative to carbon and hydrogen were investigated quantitatively: radial transport of water ice-rich migrators across the snow line into the inner part of the solar nebula where the ice evaporates; and coagulation, vertical settling and evaporation of anhydrous dust in the median plane of the inner nebula. In both cases, the maximum achievable f (sub O2) , approximately IW-4.5, produces a maximum X (sub Fa) before diffusion ceases that is a factor of >7 less than would be required for UOC chondrule precursors, even for grains only 0.1 mu m in radius and nebular cooling times as high as 10 (super 6) yr. The same dynamic models are also incapable of creating environments sufficiently oxidizing to produce olivine with X (sub Fa) = 0.15 during formation of chondrules by melting of FeO-poor precursors. If, instead, chondrule precursors were made of very FeO-rich, non-equilibrium condensates, reduction of chondrule melts by nebular gas may have been arrested before the mean X (sub Fa) of chondrule olivine could fall below 0.15 because chondrules were hot for such a short time. A nebular origin for the mineral assemblage of unequilibrated enstatite chondrites (UECs) requires f (sub O2) significantly below that of a system of solar composition. In particular, after fractionation of specific amounts of predicted high-temperature condensates, equilibrium condensation in a system whose P (super tot) = 10 (super -4) atm and whose initial composition is solar except for a C/O ratio of 0.83 yields an assemblage characterized by a very large enstatite/forsterite ratio, the presence of oldhamite and niningerite, metallic nickel-iron containing several wt% Si, and small amounts of pure silica and albitic plagioclase, very similar to the mineral assemblage of EH3 chondrites. Log f (sub O2) in this system varies from IW-8.9 at 1500 K to IW-13 at 900 K. The mechanisms proposed to date for fractionation of C, O and H from one another are quantitatively insufficient to produce the magnitude of nebular f (sub O2) variations needed to account for primitive features of UOCs and UECs.

The oxygen content of the Sun, expressed as the O/H atom ratio, is 468 ppm. This value, obtained relatively recently, is significantly lower than earlier estimates, but is supported by observations of several photospheric lines. The new, lower solar oxygen abundance (and a new, lower solar carbon abundance) are compatible with many astrophysical constraints but are in conflict with helioseismology-based constraints on the standard model of the Sun. The oxygen isotopic composition of the Sun is surprisingly poorly known, despite the fact that the Sun contains nearly all (approximately 98%) of the Solar System"s oxygen. Spectroscopy of the solar photosphere suggests a slight enhancement in (super 18) O/ (super 16) O compared to terrestrial composition, but with a precision of 6%. One measurement of solar oxygen trapped in lunar metal grains indicates that the Sun is depleted in (super 16) O by a few percent, whereas another indicates an enrichment of similar magnitude; some models predict that the Sun is enriched in (super 16) O by a few percent and others predict that solar and terrestrial oxygen are of similar isotopic composition. It is hoped that forthcoming isotopic measurements on solar wind sampled by the Genesis sample return mission will bring some closure to this issue.

Such a carbonate-dominated, sediment-deficient basin would supply carbonate-rich runoff to the structural depocenter in the Grand Wash Trough, possibly explaining the upward transition to the Hualapai Limestone facies in late Miocene time.

This plateau probably contained shallow basins, created by an extensional pulse at 12-11 Ma, at the present locations of major valleys. Between 4 and 3 Ma, this plateau was disrupted by a rapid westward step of extensional Basin and Range Province tectonism, which reactivated the Miocene faults and resulted in a linear north-south valley (the Owens Valley) with high mountain ranges on each side. This tectonic event resulted in geographic isolation and fragmentation of aquatic habitats and may have been a critical driver for speciation of aquatic organisms. Subsequent to this remarkable transformation of the landscape, the predominant influence on aquatic habitats has been very large, climate-driven fluctuations in the regional water balance that have resulted in the repeated interconnection and disconnection of the various basins that make up the paleo-Owens system. The magnitude of these fluctuations appears to have increased markedly since the early Pleistocene. Searles Lake has generally been the terminus of the Owens River, but at least once, probably at ca. 150 and/or ca. 70 ka, the system overflowed into Death Valley. During the last interglacial (marine isotope stage 5) and the Holocene, Owens Lake has been the terminus, but apparently not frequently before. These very large fluctuations in the water balance undoubtedly produced large shifts in the nature and distribution of aquatic habitats over geologically short periods of time, as well as repeatedly creating and severing connections between various parts of the larger drainage basin. This dynamic hydrological system provided the setting, and no doubt much of the impetus, for speciation, extinction, and distribution of aquatic species within the paleo-Owens system, but any paleohydrological causes will have to be extracted from a complex history.

The 275-km-long Amargosa River system drains generally southward across a large (15,540 km (super 2) ) watershed in southwestern Nevada and eastern California to its terminus in central Death Valley. This drainage basin is divided into four major subbasins along the main channel and several minor subbasins on tributaries; these subbasins contain features, including central valley lowlands surrounded by highlands that form external divides or internal paleodivides, which suggest relict individual physiographic-hydrologic basins. From north to south, the main subbasins along the main channel are: (1) an upper headwaters subbasin, which is deeply incised into mostly. Tertiary sediments and volcanic rocks; (2) an unincised low-gradient section within the Amargosa Desert; (3) a mostly incised section centered on Tecopa Valley and tributary drainages; and (4) a west to northwest-oriented mostly aggrading lower section along the axis of southern Death Valley. Adjoining subbasins are hydrologically linked by interconnecting narrows or canyon reaches that are variably incised into formerly continuous paleodivides. The most important linkages along the main channel include: (1) the Beatty narrows, which developed across a Tertiary bedrock paleodivide between the upper and Amargosa Desert subbasins during a latest Miocene-early Pliocene to middle Pleistocene interval (ca. 4-0.5 Ma); (2) the Eagle Mountain narrows, which cut into a mostly alluvial paleodivide between the Amargosa Desert and Tecopa subbasins in middle to late Pleistocene (ca. 150-100 ka) time; and (3) the Amargosa Canyon, which formed in late middle Pleistocene (ca. 200-140 ka) time through a breached, actively uplifting paleodivide between the Tecopa and southern Death Valley subbasins. Collectively, the interconnecting reaches represent discrete integration events that incrementally produced the modern drainage basin starting near Beatty sometime after 4 Ma and ending in the Salt Creek tributary in the latest Pleistocene to Holocene (post-30 ka). Potential mechanisms for drainage integration across paleodivides include basin overtopping from sedimentary infilling above paleodivide elevations, paleolake spillover, groundwater sapping, and (or) headward erosion of dissecting channels in lower-altitude subbasins. These processes are complexly influenced by fluvial responses to factors such as climatic change, local base-level differences across divides, and (or) tectonic activity (the latter only recognized in Amargosa Canyon).

Geological and biological studies have tended to support this hypothesis and a hydrological link that included the Colorado River, allowing dispersal of pupfish throughout southeastern California and western Nevada. Recent mitochondrial deoxyribonucleic acid (mtDNA) studies show a common pupfish (Cyprinodontidae) ancestry in this region with divergence beginning 3-2 Ma. We present tepbrochronologic and paleomagnetic data in the context of testing the paleohydrologic connections with respect to the common collection point of the Amargosa, Owens, and Mojave Rivers in Death Valley during successive time periods: (1) the late Pliocene to early Pleistocene (3-2 Ma), (2) early to middle Pleistocene (1.2-0.5 Ma), and (3) middle to late Pleistocene (<0.7-0.03 Ma; paleolakes Manly and Mojave). Using the 3.35 Ma Zabriskie Wash tuff and 3.28 Ma Nomlaki Tuff Member of the Tuscan and Tehama Formations, which are prominent marker beds in the region, we conclude that at 3-2 Ma, a narrow lake occupied the ancient Furnace Creek Basin and that Death Valley was not hydrologically connected with the Amargosa or Mojave Rivers. A paucity of data for Panamint Valley does not allow us to evaluate an Owens River connection to Death Valley ca. 3-2 Ma. Studies by others have shown that Death Valley was not hydrologically linked to the Amargosa, Owens, or Mojave Rivers from 1.2 to 0.5 Ma. We found no evidence that Lake Manly flooded back up the Mojave River to pluvial Lake Mojave between 0.18 and 0.12 Ma, although surface water flowed from the Amargosa and Owens Rivers to Death Valley at this time. There is also no evidence for a connection of the Owens, Amargosa, or Mojave Rivers to the Colorado River in the last 3-2 m.y. Therefore, the hypothesis that pupfish dispersed or were isolated in basins throughout southeastern California and western Nevada by such a connection is not supported. Beyond the biologically predicted time frame, however, sparse and disputed data suggest that a fluvial system connected Panamint (Owens River), Death, and Amargosa Valleys, which could account for the dispersal and isolation before 3 Ma.

The oxygen isotope stage (OIS) 2 and 6 lacustrine record is well preserved in surficial deposits, whereas the OIS 3-5 lacustrine-paludal and lacustrine record is mainly derived from an archived core sample. Amino acid racemization ratios in ostracodes and gastropods suggest that the shoreline and groundwater-discharge features that lie between -600 and 550 m elevation formed during one highstand, probably during OIS 6. A fossiliferous part of the approximately 100-m-deep core DH-1, which was drilled in the Ballarat Basin during the late 1950s, was resampled in this study. Comparison of DH-1 with core DH-3 from Panamint Valley and core OL-92 from Owens Lake suggests the 34-78-m-depth interval of DH-1 may span all or much of OIS 4. The microfauna from this depth interval indicate a saline marsh or shallow lacustrine environment, but not a large lake. The ostracode assemblage requires low ratios of alkalinity to calcium (alk/Ca) water likely indicative of solutes in deep regional groundwater sources rather than the high alk/Ca solutes common to the Owens River system. OIS 2-aged sediment from surficial deposits, a shallow auger hole, and core DH-1 contain faunas, including the ostracode Limnocythere sappaensis, which require the high alk/Ca evolved solutes common to the Owens River. The elevation of the lacustrine sediments further indicates a moderate-sized saline lake around 180-200 m depth. In the northern Lake Hill basin, a saline lake persisted until at least 16 ka, and it was succeeded by fresh, groundwater-supported wetlands, which were fully developed by ca. 12,575 (super 14) C yr B.P. and which persisted until around 10,500 (super 14) C yr B.P., when the basin became a dry playa.

Cytochrome b and ND4L sequences were analyzed by maximum likelihood methods to estimate phylogenetic branch lengths, which were calibrated to geological time with a fossil age estimate. We assume that heterogeneity in rate of evolution of mitochondrial DNA is caused in part by differences in body size, temperature, and correlated life-history traits; therefore, branch lengths are used directly to calculate rates of nucleotide substitution and ages of nodes on the phylogenetic tree. Rhinichthys osculus is estimated (by the corrected age of the oldest fossil) to have diverged from its sister species at 6.3 Ma. We estimate that speckled dace have been in the Colorado drainage for 3.6 m.y., and they have dispersed through the drainage and to former connectives, such as the Los Angeles Basin, in the past 1.9 m.y. Divergence among lineages of the upper and lower Colorado River drainages (above and below Grand Canyon) is estimated to have occurred ca. 1.9-1.3 Ma. Genetic divergence of allopatric lineages in the lower Colorado River drainage was accompanied by morphological adaptations to different stream gradients, but small genetic distances among these forms indicate recent gene flow and lack of reproductive isolation.

The Mesozoic Cordilleran orogen next to the continental margin of southwestern North America probably formed the continental divide. Mountain building migrated eastward to cause uplift of the Rocky Mountains during the Late Cretaceous to early Tertiary Laramide orogeny. Closed drainage basins that developed between the two mountain belts trapped lake waters containing fish of Atlantic affinity. Oligocene-Miocene tectonic extension fragmented the western mountain belt and created abundant closed basins that gradually filled with sediments and became conduits for dispersal of fishes of both Pacific and Atlantic affinity. Abrupt arrival of the modern Colorado River to the Mojave-Sonora Desert region at ca. 5 Ma provided a new conduit for fish dispersal. Great dissimilarities in modern fish fauna, including differences in their mitochondrial deoxyribonucleic acid (DNA), indicate that late Miocene runoff from the Colorado Plateau did not flow down the Platte or Rio Grande, or through the Lake Bonneville Basin. Fossil fishes from the upper Miocene part of the Bidahochi Formation on the Colorado Plateau have characteristics that reflect a habitat of large, swift-moving waters, and they are closely related to fossil fishes associated with the Snake and Sacramento Rivers. This evidence suggests that influx of fishes from the ancestral Snake River involved a major drainage, not merely small headwater transfers.

A fluctuating, increasingly saline, terminal lake survived into the late Holocene until upstream water diversions to the Los Angeles Aqueduct began in 1913. Shoreline fragments and beach stratigraphy indicate that the lake reached its highest late Pleistocene level around 23.5 ka, during the Last Glacial Maximum, when it was fed by meltwaters from Sierra Nevada glaciers and spilled southward to Searles Lake and beyond. The lake then fell to relatively low levels after 16.5 ka before experiencing terminal Pleistocene oscillations related to hydroclimatic forcing, which involved changing regional precipitation regimes rather than major inputs from Sierra Nevada glaciers. Two major transgressions occurred. The first culminated around 14.3 ka and was probably related to a cooler, wetter regional climate. The second culminated around 12.8 ka and was linked to the earlier wetter phase of the Younger Dryas cold event. However, the high late Pleistocene shoreline is deformed, and the highest beach ranges in elevation from 1140 m to 1167 m above sea level. If the terminal Pleistocene lake overflowed, as suggested here, then its outlet has also been raised since 12.8 ka. This deformation appears to have involved uplift of the Coso Range magmatic complex relative to subsidence and faulting within the Owens Lake graben between the Sierra Nevada and Inyo Mountains frontal faults. Such deformation confounds simple hydroclimatic explanations of lake behavior and must be incorporated into models that seek to interpret the changing form and geochemistry of Owens Lake and the frequency of its spillage southward to Searles Lake.

Based on new field observations, radiocarbon ages, and soil development, we propose modifications to previously published hypotheses on the timing of the last 543 m above sea level (masl) highstand of Lake Manix, the timing of the first discharge eastward, and the time required to cut Afton Canyon between the two basins. Subtle beach barriers, wave-cut scarps, and lagged beach gravels indicate that Lake Manix reached highstands between 547 and 558 masl at least twice prior to its previously known 543 m highstands. Properties of soils formed on beach barriers at 547-549 masl compared to soils on dated deposits suggest an age of older than 35 cal ka for this highstand. Calibrated radiocarbon ages for three lacustrine highstands at or near 543 masl are ca. 40-35 ka, 33-30 ka, and 27-25 ka. Lake Manix periodically discharged down a drainage presently located on the north rim of Afton Canyon at 539 masl. Soil development estimated from multiple buried soils within fluvial deposits and overlying fan deposits suggests that discharge was coeval with or somewhat older than the 547-549 m highstand, and that fluvial aggradation in this drainageway was followed by a period of relative landscape stability and episodic burial by alluvial-fan deposits. Strath terraces below these highest fluvial deposits, but above the canyon rim, record initial incision of the Lake Manix threshold. Surface and soil properties indicate that they are latest Pleistocene to early Holocene in age, similar to the previously studied strath terraces that are inset well below the rim and below the basal lake sediments. We suggest that the higher straths above the rim formed no earlier than ca. 25 cal ka. We interpret the soils, stratigraphy, and fluvial landforms in the canyon to indicate relatively rapid incision of Afton Canyon to the depth of the bedrock floor of Lake Manix, followed by intermittent, gradual bedrock incision.

However, the age, distribution, and paleoclimatic I context of higher-elevation shoreline features have not been formally documented. We describe the location and characteristics of wave-formed erosional and depositional features, as well as fluvial strath terraces that grade into an older shoreline of pluvial Owens Lake. These pluvial-lacustrine features are described between the Olancha area to the south and Poverty Hills area to the north, and they appear to be vertically deformed approximately 20 = 4 m across the active oblique-dextral Owens Valley fault zone. They occur at elevations from 1176 to 1182 m along the lower flanks of the Inyo Mountains and Coso Range east of the fault zone to as high as approximately 1204 m west of the fault zone. This relict shoreline, referred to as the 1180 m shoreline, lies approximately 20-40 m higher than the previously documented Last Glacial Maximum shoreline at approximately 1160 m, which occupied the valley during marine isotope stage 2 (MIS 2). Crosscutting relations of wave-formed platforms, notches, and sandy beach deposits, as well as strath terraces on lava flows of the Big Pine volcanic field, bracket the age of the 1180 m shoreline to the time interval between ca. 340+ or -60 ka and ca. 130+ or -50 ka. This interval includes marine oxygen isotope stages 8-6 (MIS 8-6), corresponding to 260-240 ka and 185-130 ka. respectively. An additional age estimate for this shoreline is provided by a cosmogenic Cl model age of ca. 160+ or -32 ka on reefal tufa at approximately 1170 m elevation from the southeastern margin of the valley. This (super 36) Cl model age corroborates the constraining ages based on dated lava flows and refines the lake age to the MIS 6 interval. Documentation of this larger pluvial Owens Lake offers insight to the hydrologic balance along the east side of the southern Sierra Nevada and will assist with future regional paleoclimatic models within the western Basin and Range.

Springsnails (Hydrobiidae: Pyrgulopsis) are one of the most diverse elements of this fauna, and they are thought to have evolved in association with late Tertiary rearrangements of landscape and drainage. We assembled a molecular phylogeny for this fauna to investigate its evolutionary development in relation to regional geological history. Sequences for two mitochondrial genes were obtained from 80 populations representing 13 of the 14 Death Valley system springsnail species, and 31 extralimital congeners. Combined analyses of the 1188 base-pair data set consistently depicted the Death Valley system fauna as a poly-phyletic assemblage of eight or nine lineages. Based on a molecular clock, the six lineages endemic to the Death Valley system were estimated to be minimally Pliocene in age, which is concordant with inception of regional topographic closure during this time period. The single endemic lineage with a well-resolved sister relationship was closest to a species from the upper Gila River basin, which also suggests an old divergence event. Three other lineages shared a pattern of shallow structuring (divergence events younger than 0.7 Ma) across multiple drainage basins, some of which have long been isolated. This suggests that, contrary to previous thought, regional springsnail biogeography has been shaped in part by geologically recent (Pleistocene) dispersal, and, in some places, it has occurred by means other than spread through continuous reaches of aquatic habitat.

Fossils of marine, brackish, and freshwater organisms in the Bouse Formation have been interpreted to indicate an estuarine environment associated with early opening of the nearby Gulf of California. Regional uplift since 5 Ma is required to position the estuarine Bouse Formation at present elevations as high as 555 m, where greater uplift is required in the north. We present a compilation of Bouse Formation elevations that is consistent with Bouse deposition in lakes, with an abrupt 225 m northward increase in maximum Bouse elevations at Topock gorge north of Lake Havasu. Within Blythe and Havasu. Basins, maximum Bouse elevations are 330 m above sea level in three widely spaced areas and reveal no evidence of regional tilting. To the north in Mohave Basin, numerous Bouse outcrops above 480 m elevation include three widely spaced sites where the Bouse Formation is exposed at 536-555 m. Numerical simulations of initial Colorado River inflow to a sequence of closed basins along the lower Colorado River corridor model a history of lake filling, spilling, evaporation and salt concentration, and outflow-channel incision. The simulations support the plausibility of evaporative concentration of Colorado River water to seawater-level salinities in Blythe Basin and indicate that such salinities could have remained stable for as long as 20-30 k.y. We infer that fossil marine organisms in the Bouse Formation, restricted to the southern (Blythe) basin, reflect colonization of a salty lake by a small number of species that were transported by birds.

Aggradational, finely bedded reddish mud, clay, and silt are underlain and overlain by cross-bedded to plane-bedded fine sand and silt. That sequence is commonly disconformably overlain by up to 15 m of coarse sand, rounded exotic gravel, and angular, locally derived gravel. Luminescence dates on the fine sediments range from ca. 40 ka to 70 ka, considering collective uncertainties. A section of fine-grained sediments over a vertical range of 15 m shows normal polarity magnetization and little apparent secular variation beyond dispersion that can be explained by compaction. Aggradation on large local tributaries such as Las Vegas Wash appears to have been coeval with that of the Colorado River. The upper limits of erosional remnants of the sequence define a steeper grade above the historical river, and these late Pleistocene deposits are greater than 100 m above the modern river north of 35 degrees N. Terrace gravels inset below the upper limit of the aggradational sequence yield (super 230) Th dates that range from ca. 32 ka to 60 ka and indicate that degradation of the river system in this area closely followed aggradation. The thick sequence of rhythmically bedded mud and silt possibly indicates settings that were ponded laterally between valley slopes and levees of the aggrading river. Potential driving mechanisms for such aggradation and degradation include sediment-yield response to climate change, drought, fire, vegetation-ecosystem dynamics, glaciation, paleofloods, groundwater discharge, and building and destruction of natural dams produced by volcanism and landslides.

These sediments resulted from two or more aggradational episodes in Pliocene and Pleistocene times following initial incision during the early Pliocene. A review of the stratigraphic evidence of major swings in river elevation over the last 5 m.y. from alternating degradation and aggradation episodes establishes a framework for understanding the incision and filling of the paleovalleys. The paleo-valleys are found mostly along narrow bedrock canyon reaches of the river, where divides of bedrock or old deposits separate them from the modern river. The paleovalleys are interpreted to have stemmed from periods of aggradation that filled and broadened the river valley, burying low uplands in the canyon reaches into which later channel positions were entrenched during subsequent degradation episodes. The aggradation-degradation cycles resulted in the stranding of incised river valleys that range in elevation from near the modern river to 350 m above it.

These data represent an intrabiomic record that can serve as a proxy for climate change in the Carboniferous tropics. The short-term climatic changes that accompanied the alternations between glacial and interglacial intervals did not alter the persistence of the ecological structure of the landscape. Even after floras had been extirpated over large parts of the North American continent in response to marine transgressions, the same plants and plant communities repeatedly returned when the sea receded. However, at the Westphalian-Stephanian boundary (approximately Desmoinesian-Missourian; Moscovian-Kasimovian boundary), major vegetational changes occurred that suggest a significant environmental threshold had been exceeded. Entire clades (most tree lycopsids and medullosans with very large seeds) became extinct, and tree ferns became dominant, changing the aspect of the ecological landscape. This change reflects the overall warming of Earth's climate, greater seasonality, and shorter periods of wet conditions in the tropics of the late Pennsylvanian.

(2007) as the result of a great 20 m megatsunami at sea, propagating out across the North Atlantic from the Canary Islands, cresting, and rolling up and over the Bermuda platform. However, no middle Pleistocene tsunami deposits have been reported elsewhere on Bermuda or anywhere else around the North Atlantic rim. The tsunami origin is unsupportable whereas the available evidence unequivocally establishes a +21 m eustatic sea level during the middle Pleistocene MIS 11 interglacial.

Principal component analysis of the data suggests that the smaller footprints from the Valtos Sandstone and Kilmaluag Formations are indistinguishable from the footprints of the Sundance Formation. The single footprint from the Lealt Shale Formation is similar to the larger footprints from the Valtos Sandstone Formation. The footprints from the Duntulm and Gypsum Springs Formations form distinct groupings from all other footprints. Four different groupings of dinosaur footprints can be recognized from the principal component analysis that may represent at least four different types of dinosaur.

For the eruption period, pines near Paricutin have slightly suppressed ring widths plus high inter-annual variability of width. Wood anatomy changes include traumatic resin ducts and thin bands of false latewood. Dendrochemistry of tree rings shows little temporal variation in most elements, but beginning in 1943 sulfur content increased in rings of four trees and phosphorus content increased in rings of two trees. Hypotheses for increased S and P include new availability of pre-existing soil S and P and/or new input of S and P from the tephra itself. Pines at Paricutin also show suppressed ring widths for five years beginning in 1970, and had the eruption date not been known, the most likely conclusion from ring-width data alone would have been an eruption from 1970 to 1974. However, the 1970s suppression was in response to defoliation by a pine sawfly outbreak, not an eruption. For dendrochronological dating of cinder-cone eruptions, a combination of multiple characteristics (width, chemistry, and anatomy) would be more reliable than depending on any one characteristic alone.

(Afar Locality) 333 hominin locality provides paleoenvironmental information at geographic scales of hundreds of meters to kilometers as well as insights regarding alluvial deposition and pedogenesis in the middle Denen Dora Member of the Hadar Formation. A.L. 333 is dated at ca. 3.2 Ma and has produced over 260 surface and excavated specimens of Australopithecus afarensis. It represents an unusual source of high-resolution information about the paleoenvironmental context of this hominin. The in situ hominin fossils are associated with the final stages of filling of a paleochannel and were buried prior to the formation of overlying paleosols. Preserved bedding structures in the fine-grained hominin-producing strata provide evidence that the abandoned channel continued to aggrade prior to the onset of sustained pedogenesis. Pedogenic carbonates associated with the hominin level thus postdate the death and burial of the hominins, possibly by centuries to millennia. The reconstructed paleodrainage of the DD-2 sandstone (DD-2s) is oriented south to north and consists of a trunk channel, approximately 40 m wide and 3-5 m deep, connecting a tributary system south of A.L. 333 to a distributary system to the north, which likely ended on the deltaic plain associated with the basin's depocenter. The hominin concentration occurs in the upper part of the fill of the trunk channel. The burial of the hominin remains involved fine-grained deposition indicating low-energy, seasonal flood events, and there is no sedimentological evidence for a high-energy, catastrophic flood that could have caused the demise of the hominins.

Oxygen is an abundant element in meteorites and presumably in most asteroids. Spectral reflectance measurements of asteroids in the visible and near-infrared can identify oxygen-bearing minerals such as those found in the olivine, pyroxene, and serpentine groups due to their distinctive absorption features. Interpretation of the mineralogy of asteroids is complicated by the effects of space weathering, which tends to redden and darken the surfaces of asteroids. Asteroids are primarily classified into a number of taxonomic classes and subclasses according to their spectral properties in the visible wavelength region. However, asteroids with similar spectral properties in the visible may have different spectral properties in the near-infrared and, therefore, different interpreted mineralogies. Definite trends in the abundances of different taxonomic classes versus heliocentric distance are apparent. These trends appear to be a function of both composition differences and degree of heating. However, dynamical processes have significantly affected these trends. Close observation of asteroids by spacecraft, such as NEAR-Shoemaker to 433 Eros and Hayabusa to 25143 Itokawa, are currently the best way to discern the mineralogies of individual asteroids.

Oxygen fugacity appears to vary laterally, as well as vertically, by as much as a factor of 10 (super 4) . As flow within the interior of the Earth and other terrestrial planets occurs due to the (mostly) solid-state deformation of rocks, an understanding of the effect of oxygen fugacity on creep is critical in modeling planetary interior dynamical behavior. This is especially important for the asthenosphere, that anomalously weak region in the uppermost mantle that accommodates isostasy and largely decouples mantle convection from plate motions. Experimental studies of the rheological behavior of iron-bearing minerals have demonstrated that oxygen fugacity can play an important role in deformation. We have shown that olivine rich rocks deformed near FMQ deform in the dislocation creep regime about a factor of 6 faster when buffered near FMQ than at IW. Experiments on olivine single crystals and aggregates indicate that this difference in behavior results from an increase in the concentration of silicon vacancies under more oxidizing conditions, as dislocation creep is rate-limited by the climb of dislocations, which is controlled by diffusion of silicon defects. Although fewer data are available for the effects of oxygen fugacity on pyroxene deformation, clinopyroxene appears to be stronger under more oxidizing conditions, while the data on orthopyroxene deformation show no dependence on oxygen fugacity. These results indicate that vertical and lateral variations in oxygen fugacity may result in, at most, an order of magnitude difference in viscosity, while other factors, such as water fugacity and lithology may be more significant.

Abundances of condensable species and noble gases in well-mixed atmospheres can distinguish among several giant planet formation scenarios, and satellite densities are first order measurements of ice:rock ratios. Recent work on protosolar abundances, relying on three-dimensional spectroscopic modeling of the solar photosphere, provides the framework for the interpretation of measurements. Model densities of protoplanetary disk condensates are shown as a function of carbon partitioning between CO, CH (sub 4) and organics. Comparison with observed satellite densities shows that Saturn"s icy satellites are inconsistent with solar composition, and must either have formed in a water-rich environment or have suffered a complex collisional history. The larger satellites of the giant planets are consistent with solar composition, with densities that speak of variation in the partitioning of carbon. Thermochemical equilibrium calculations predict water as the deepest tropospheric cloud on Jupiter, the planet with the best-constrained bulk water abundance. Yet cloud base pressure levels, remote spectroscopic water vapor measurements, and in situ mass-spectral measurements have all been unable to distinguish conclusively between subsolar and supersolar Jovian bulk water abundances, due to modeling assumptions and/or the spatially-variable water vapor distribution in Jupiter's troposphere. Modeling of images of lightning flashes is consistent with supersolar water abundances. Galileo probe measurements are consistent with an enrichment factor of 4+ or -2 over the protosolar values for most volatiles other than water (C, N, S, and the noble gases Ar, Kr, and Xe). With that of oxygen unknown, Jupiter's enrichments of other volatiles could be explained in terms of enrichment by heretofore unidentified solar composition icy planetesimals, by planetesimals containing volatiles trapped in water ice clathrates, or by enriched gas in the evolved disk. All models involving delivery of elements by planetesimals require planetesimal formation at temperatures below 40 K, to trap argon and molecular nitrogen. Although atmospheric C/H ratios have been measured for all four giant planets, a conclusive test of the competing formation scenarios cannot be made until O/H is measured on all four planets (extremely difficult on Uranus and Neptune), and abundances of the other volatiles and noble gases are measured for the outer three.

In the absence of mantle xenoliths in samples from the Moon, Mars and differentiated asteroids, the basalt-mantle source relationship must be extrapolated from what is known about the Earth in order to probe the redox state of these planetary interiors. A review of current knowledge regarding the basalt-mantle source relationship for the Earth provides insights into the advantages and pitfalls of determining mantle redox state. The range of currently available oxybarometers, including thermodynamic models based on ferrous-ferric mineral equilibria and multivalent cation analysis are surveyed and their limitations presented. The result is a basis for the informed interpretation of the oxygen fugacity of planetary basalts, and new insights into the role of C-H-O volatiles in the terrestrial planets.

This chapter will briefly review the abundances of important light stable isotopes, demonstrate the link between abundance and atomic weight, introduce the notations and diagrams that are commonly used to report isotopic measurements, describe and partially explain the types of fractionation effects known to occur in nature, and direct the reader to more comprehensive sources of information on each subject. The special techniques needed to make accurate isotopic measurements gave rise to special notation for reporting stable isotope data, and these notations in turn gave rise to special diagrams that emphasize compositional differences and facilitate interpretation. Fundamental definitions are the isotope ratio R, representing the ratio of the abundance of a heavy isotope to that of a lighter, typically much more common isotope, and the isotopic fractionation factor alpha , representing the quotient R (sub A) /R (sub B) of the isotope ratios of two substances A and B. Under equilibrium conditions, lnalpha can theoretically vary linearly with 1/T at low temperatures or with 1/T (super 2) at high temperatures, forming the basis for a standard graph. For practical reasons the ratio R is difficult to measure and inconvenient to report, so stable isotope abundances are usually reported as delta values (delta -values) that describe their deviations from a defined "standard" material. Thus, the most important diagram for data interpretation is the "delta -delta plot" where the delta -values of two coexisting phases are simply plotted against each other. In systems where two different heavy isotopes exist, two different delta values may be defined, each normalizing the abundance of one of the heavy isotopes to the common light isotope. In such cases, a very important diagram called the "three isotope" plot involves simply plotting these two different delta -values against each other for a given material, and the slopes of data arrays on such graphs can be used to distinguish ordinary "mass-dependent" fractionation (MDF) effects from "non-mass-dependent" fractionations (NMF). Numerous algebraic convolutions of the above definitions have been made, providing special definitions that can elucidate different phenomena. The processes that govern isotope distribution have become progressively better understood, yet recent studies show that these processes are more diverse than anticipated only ten years ago.

We have examined three specific issues: possible correlations of Delta (super 17) O with (i) oxidation state; (ii) bulk chondrite chemistry; and (iii) bulk planetary properties. Isolated grains and chondrules from several carbonaceous chondrite groups exhibit good to weak positive correlations between Delta (super 17) O and olivine fayalite content, and whole rock ureilite samples show a positive correlation of Delta (super 17) O with olivine fayalite content. These are consistent with oxidation of Fe metal by (super 17) O-, (super 18) O-enriched oxygen in the precursor materials that formed these objects. In contrast, oxygen isotopic and major element compositions of ferromagnesian phases in ordinary chondrite chondrules, and in bulk chondrites do not show a correlation. Thus, there is no compelling evidence that oxidation of nebular materials was tightly linked to gas species carrying anomalous O. Using average chondrite group compositions, we demonstrate that significant negative correlations of refractory lithophile element/Mg and refractory siderophile element/Ni with Delta (super 17) O exist. Refractory inclusions (CAIs and AOAs) are modally rare in many chondrite types that exhibit substantial range in Delta (super 17) O. Thus, the refractory component in these chondrites must occur in a crypto-component, e.g. material dissolved in chondrule melts during chondrule formation. Significant positive correlations of moderately volatile elements/Mg with Delta (super 17) O are not simply explained by incomplete mixing of (super 16) O-enriched refractory grains, but are broadly consistent with nebula-based mechanisms of non-mass-dependent oxygen isotope fractionation. The estimated compositions of the primitive mantles of the Earth, Mars and 4 Vesta have some compositional, redox and isotopic properties that vary with heliocentric distance. However, Delta (super 17) O does not vary monotonically in this sequence, indicating a decoupling of planetary O isotopic composition from other compositional characteristics.

This chapter reviews the chemistry of oxygen (elemental andisotopic) in lunar, planetary, and Earth surface reservoirs. The discussion begins with a brief review of the relative abundances of oxygen isotopes in planetary materials, including lunar samples, the SNC (Martian) meteorites, and components that are inferred to come from Martian surface pools. This is followed by a brief, largely historical account of the development of oxygen isotope geochemistry in Earth-surface materials. The discussion then transitions, using an Earth systems perspective, into an overview of developments in oxygen isotope geochemistry of atmospheric compounds. This treatment includes recent studies that (1) use high-precision measurements of delta (super 17) O and delta (super 18) O to characterize atmospheric oxygen; (2) apply information about isotopically substituted species (isotopologs) for characterizing the position-dependent isotopic fractionations of some oxygen-bearing atmospheric species; and (3) investigate non mass-dependent isotopic fractionations in ozone and other atmospheric species. The discussion then examines the evidence and models that point to change in the oxygen cycle and oxidation chemistry in Earth surface environments over the course of geologic time. We use the subdivisions of the Earth systems--the hydrosphere, geosphere and biosphere, as a basis for examining these changes. This record is explored in the context of hypotheses and data that relate to the nature of the changes and transformations in the oxidation state of these different components of the Earth's surface environments. We conclude with a brief accounting of areas of research where scientific inquiry is presently very active.

About 50-90% of the PP was phosphate bound to iron oxides (Fe-P), and 8-30% was organic P (org-P). Loosely sorbed phosphate (sorb-P), detrital apatite, and authigenic plus biogenic apatite each made up 16 (the Redfield ratio) and ranged up to >700, while at the saline end of the gradient the ratio was generally <16 and ranged down to <1.5. Our observations are consistent with the hypothesis that phosphate is released from terrigenous sediments when they are deposited in saline portions of the estuary where sulfide may enhance dissolution of Fe-P and form Fe sulfide precipitates. Such phosphate release may contribute to the generally observed switch from phosphorus limitation in freshwater to nitrogen limitation in coastal marine water.

Although palynological data are subject to study by analytical techniques to answer questions regarding evolution, paleoclimate, and biogeography, the use of palynological data has often been qualitative, thus limiting their interpretation. Here, five techniques that can be used with palynological data are presented. These deal with diversity (number of species, evenness, diversity indices, and abundance distribution models), comparing similarities among samples, building a composite section, constructing species ranges, and estimating edge effects. The code necessary to perform these techniques has been included using R for Statistical Computing. R is an open-source and powerful statistical software available freely to anyone worldwide.

Seventeen nests of Meglaopta atra from the highlands of Chiriqui Province, Panama, were collected at the end of the dry season when brood rearing is expected to be at its peak. Most nests contained single females; within multifemale nests only one female possessed enlarged ovarioles, although some non-reproductive individuals were inseminated. In two of these nests reproductive individuals were clearly larger in body size than nestmates, but body size variation and macrocephaly were equivalent to those found in other Neotropical augochlorines. There was no evidence of a non-reproductive worker-like caste and multifemale nests did not appear to be more productive than solitary nests, which may represent pre-reproductive assemblages. Megalopta atra appears to be isolated by altitude from co-geners common in Panama, this is discussed in comparison with temperate halictine bees, in which environmental clines separate solitary from social populations.

This ambitious field program, known inside and outside the Institution by its familiar abbreviation AMP, was conceived, coordinated, and impelled by Henry W. Setzer, curator in the Division of Mammals, U.S. National Museum of Natural History, from 1948 to 1978. By its completion, the field program had enlisted the energies of some 40 main collectors, encompassed 20 countries distributed across the northern, western, and southern sectors of the African continent, and procured over 60,000 mammal specimens from 788 major collecting localities (Map 1). Although AMP specimens have been used incidentally in numerous faunal reports and taxonomic studies, foremost of mammals but also of the abundant ectoparasites collected from them, nowhere are the scope and results of the project itself synthesized. Our central objective is to document here the basic geographic data of the African Mammal Project in the form of a generously annotated gazetteer that includes localities surveyed as determined from specimen labels and field catalogs; coordinate data for those localities as given by collectors or georeferenced by us; names of collectors and dates of visit at each locality; general ecological descriptions, both as quoted directly from field journals and as captured in habitat photographs by AMP collectors; and lists of mammalian genera obtained at each site. Secondary goals are to provide the historical background to the African Mammal Project, its genesis and scientific purpose as originally developed by Setzer, and to address in broad terms its taxonomic and geographic results.

This prediction was tested in the shrimp Pontonia margarita, which inhabits the pearl oyster Pinctada mazatlanica. A total of 68 oysters were collected from the intertidal and shallow subtidal at two islands (Islas Secas [N 27 degree 55', W 82 degree 03'] and Isla de La Coiba [N 27 degree 50', W 97 degree 03']) off the eastern tropical Pacific coast on 15 and 17 March 2007, respectively. The population structure, distribution, male-female association pattern, and relative growth of the major claw and pleura of the second abdominal segment of each shrimp retrieved were examined. Shrimps were found as heterosexual pairs in the mantle cavity of hosts more frequently than would be expected by chance alone. Males occurred with females in the same host, independent of the reproductive condition of the female or the stage of development of brooded embryos. This observation, and strong correlations between the host and shrimp body size in both males and females suggest a long-term association between males and females in each host. Sexual dimorphism in body size was minor, with males being just slightly smaller than females. In agreement with predictions for monogamous species, the major claw of males did not display positive allometry, which has been generally reported for polygamous shrimps. In turn, the pleura of the second abdomen presented negative allometry in males but positive allometry in females. All available information suggests that Pontonia margarita has a socially monogamous mating system with males and females forming exclusive pairs in their hosts.

Ballast water from three tanks was subjected for a few seconds to temperatures ranging from 55 super(o)C to 80 super(o)C. The water was heated using the vessel's heat exchanger steam and a second heat exchanger was used to pre-heat and cool down the water. The treatment was effective at causing mortality of bacteria, phytoplankton and zooplankton. The International Maritime Organization (IMO) standard was not agreed before this study was carried out, but comparing our results gives a broad indication that the IMO standard would have been met in some of the tests for the zooplankton, in all the tests for the phytoplankton; and probably on most occasions for the bacteria.

Archie Carr described one of these, Playa Chiriqui, in 1956 as the most important nesting beach for the hawksbill turtle in the Caribbean. During the mid-1900s, the nesting population was heavily exploited for tortoiseshell to supply international trade, and it experienced a huge decline. Encouraged by increased nesting levels at a few sites in the Caribbean where rigorous, long-term protection has been provided, we initiated this project to study and hopefully restore the remnant Chiriqui population. The project began in June 2003 in collaboration with the indigenous communities, Autoridad Nacional del Ambiente de Panama (ANAM), and the traditional authorities of the Comarca Ngoebe-Bugle. Daily surveys were carried out from June through October, resulting in the documentation of 350 hawksbill nests on Playa Chiriqui, 19 on Escudo de Veraguas, and 100 on the Zapatilla Cays in the Bastimentos Island National Marine Park. Data were also collected on the regionally significant leatherback turtle (Dermochelys coriacea) population at Playa Chiriqui. Also, the first seminar for teachers on marine environmental education took place in August 2003 at Rio Cana. Restoration of this historically important population is highly dependent on the continued ban on international trade in hawksbill shell through CITES and on improved enforcement of laws banning domestic trade.

Rapid growth of this population over the past few decades from 28 to 166 horses negatively impacts native species and ecological processes on the island. Since 1994, contraception via porcine zona pellucida vaccine has been used to control horse numbers, although herd reduction has been slower than initially expected, leading NPS to consider other management options. An individual-based stochastic simulation model was developed using the Vortex software program to examine the effects of different management strategies on the population. Data from the managed population were used to populate the model parameters. Model projections over the next 50 years using current management practices show an average rate of population decline of 13% per year, suggesting that the population will reach the management target of 80-100 horses in 5-8 years. The effectiveness of contraception to reduce the herd and maintain it at various target sizes of 20-100 horses was also assessed. The accumulation of inbreeding at each target population size was also modelled.

This includes the volatile organic compounds formaldehyde (HCHO), a standard data product, and glyoxal (CHO-CHO), current an off-line data product that will be converted to a standard product in the near future. HCHO sources include oxidation of methane and isoprene. HCHO is the major proxy for satellite measurements of VOC emissions and an indicator for urban air quality. CHO-CHO, a VOC detected in ground-based measurements in Mexico City and the Pearl River Delta, China, is produced from the oxidation of numerous other VOCs. Unlike HCHO, it is not affected directly by vehicle emissions. It has a slightly shorter life time. OMI is in the unique position to observe both gases simultaneously with tropospheric NO2 and ozone, with daily global coverage, and with an equator crossing time when VOC concentrations are close to their daily maxima and the polluted urban atmosphere is photochemically active (1338h). Recent improvements in radiance calibration and dark current corrections of OMI level-1 spectra have lead to great enhancements in the retrievals of HCHOand CHO-CHO, to the point where transport and correlation studies of and between the various air quality components on very short time spans have become feasible. This will greatly advance our understanding of VOC production on a global scale, as well as our knowledge on VOC-ozone interactions in polluted environments and the production of tropospheric ozone. We present recent results of simultaneous HCHO and CHO-CHO observations, in combination with tropospheric ozone and NO2 observations from OMI. We give an update on data availability, and identify outstanding challenges in the satellite-based remote sensing of these VOCs.

Figs are pollinated by highly specific, but short-lived (1-3 days), wasps that breed inside the inflorescence. Thus, continuous flowering at the population-level is a necessary condition for the mutualism to persist. In other respects, however, the ecology of co-occurring fig species varies greatly. Leaf and inflorescence production among 15 species of monoecious hemi-epiphytic fig (Ficus; section Conosyce) were studied over 4 years in an aseasonal lowland rainforest in Borneo. At the community-level, leaf production was significantly reduced following wetter periods. Many individuals (28%) did not flower during the entire 4 year period. Of individuals that flowered, the mean frequency of reproductive episodes was low and varied from 0.3 to 1.7 times per year. Species with smaller fruit flowered significantly more than those with large fruit, which translated into a substantial difference in fruit production (10.6 vs 1.9 kg pulp dry weight ha super(-1) yr super(-1), respectively). Among species pollinated by different wasp genera, there was a significant difference in the mean densities of individuals with receptive inflorescences, and there was a substantial difference in the duration of the wasp emergence phase. The predicted mean minimum distance from a plant with wasps emerging to a receptive individual was, thus, very different between wasp genera; and varied from 3.6 km to 31.8 km across species. Management of protected areas should take into account the low levels of fruit production, especially of species with large fruit, and that fig populations must be dependent on wasps arriving from forests over a wide landscape.

This growth has been attributed to increased human development in the region, as ravens have a commensal relationship with humans and feed extensively at landfills and on road-killed wildlife. Ravens, as a partially subsidized predator, also represent a problem for native desert wildlife, in particular threatened desert tortoises (Gopherus agassizii). However, it is unclear whether the more than 15-fold population increase is due to in situ population growth or to immigration from adjacent regions where ravens have been historically common. Ravens were sampled for genetic analysis at several local sites within five major areas: the West Mojave Desert (California), East Mojave Desert (southern Nevada), southern coastal California, northern coastal California (Bay Area), and northern Nevada (Great Basin). Analyses of mtDNA control region sequences reveal an increased frequency of raven 'Holarctic clade' haplotypes from south to north inland, with 'California clade' haplotypes nearly fixed in the California populations. There was significant structuring among regions for mtDNA, with high F sub(ST) values among sampling regions, especially between the Nevada and California samples. Analyses of eight microsatellite loci reveal a mostly similar pattern of regional population structure, with considerably smaller, but mostly significant, values. The greater mtDNA divergences may be due to lower female dispersal relative to males, lower N sub(e), or effects of high mutation rates on maximal values of F sub(ST). Analyses indicate recent population growth in the West Mojave Desert and a bottleneck in the northern California populations. While we cannot rule out in situ population growth as a factor, patterns of movement inferred from our data suggest that the increase in raven populations in the West Mojave Desert resulted from movements from southern California and the Central Valley. Ravens in the East Mojave Desert are more similar to ones from northern Nevada, indicating movement between those regions. If this interpretation of high gene flow into the Mojave Desert is correct, then efforts to manage raven numbers by local control may not be optimally effective.

We found multiple instances within both tpi and g3pdh genes in which different haplotypes were not monophyletic by species. Haplotype and reconciliation analyses suggested that genetic exchange among closely related figs is necessary to fully explain the patterns. In contrast, analyses of multiple loci from multiple individuals in the wasps are monophyletic by species, producing a well resolved species phytogeny. Although combining fig genetic data sets produced a resolved and robust fig topology, no fig phytogenies based on either combined or individual gene trees showed any significant correspondence with the wasp tree. Recent studies have shown that many of the fig species considered here have multiple pollinators and several share genetically indistinguishable pollinators. Together with these genetic results, it appears that a strict co-speciation model does not adequately describe the general evolutionary dynamics of the fig/wasp mutualism, particularly for sympatric, closely related species (within section). Importantly, these results emphasize the need to consider multiple genes, multiple individuals, and systematic scale in order to conduct and interpret robust co-phylogenetic studies of figs and their pollinating wasps.

Plasticity in PWF duration may ensure that pups of variable body condition depart for sea with adequate energy reserves. To test this hypothesis, we examined body condition of 30 gray seal pups at weaning and monitored their PWF duration. On average, fat accounted for [image] of their [image] -kg weaning mass. Although fasting duration averaged [image] d, there was considerable variation in fasting duration (9 to >31 d) and the resulting age when pups departed to sea (26 to >49 d). Percent fat at weaning (38.6%- 54.6%) was positively correlated with fasting duration . In contrast, total body gross energy (735.3-1,447.4 MJ) and body mass (39.0-66.0 kg) were not correlated with fasting duration. Thus, body composition, not overall body reserves, predicted fasting duration, but the effect was weak, indicating that other factors also account for the observed variation in fasting duration. We speculate that pups with greater percent fat more effectively utilized lipid and conserved protein while meeting metabolic costs throughout the PWF. As a result, fatter pups extended the PWF duration, which may be critical for development of diving physiology and may have facilitated their survivorship to age 1.

Here, we examine the influence of anthropogenic habitat changes on traits typically associated with natural and sexual selection in the little greenbul (Andropadus virens), an African rainforest bird species. Using satellite remote-sensing and field survey data, we classified habitats into nonhuman-altered mature and human-altered secondary forest. Mature rainforest consisted of pristine rainforest, with little or no human influence, and secondary forest was characterized by plantations of coffee and cacao and high human impacts. Andropadus virens abundance was higher in secondary forest, and populations inhabiting mature rainforest were significantly larger in wing and tarsus length and bill size; characters often correlated with fitness. To assess the extent to which characters important in sexual section and mate choice might be influenced by habitat change, we also examined differences in plumage colour and song. Plumage colour and the variance in plumage luminance were found to differ between forest types, and song duration was found to be significantly longer in mature forest. The possible adaptive significance of these differences in traits is discussed. Despite relatively high levels of gene flow across habitats, amplified fragment length polymorphism analysis revealed that a small proportion of high-F sub(ST) loci differentiated mature from secondary forest populations. These loci were significant outliers against neutral expectations in a simulation analysis, suggesting a role for divergent selection in differentiation across habitats. A distance-based redundancy analysis further showed that forest type as defined by remote-sensing variables was significantly associated with genetic dissimilarities between habitats, even when controlling for distance. The observed shifts in morphology, plumage and song were consistent with divergent selection on heritable variation, but a role for plasticity cannot be ruled out. Results suggest that anthropogenic habitat changes may have evolutionary consequences, with implications for conservation and restoration.

Our preliminary survey of 24 candidates contains 10 metal-poor galaxies of which 4 have log(O/H)+12<7.65, some of the lowest-metallicity blue compact galaxies known to date. Interestingly, our sample of metal-poor galaxies have systematically lower metallicity for their luminosity than comparable samples of blue compact galaxies, dwarf irregulars, and normal star-forming galaxies. Our metal-poor galaxies share very similar properties, however, with the host galaxies of nearby long-duration gamma-ray bursts (GRBs), including similar metallicity, stellar ages, and star formation rates. We use Hbeta to measure the number of OB stars present in our galaxies and estimate a core-collapse supernova rate of approximately 10 (super -3) yr (super -1) . A larger sample of metal-poor galaxies may provide new clues about the environment where GRBs form and may provide a list of potential GRB hosts. Copyright (Copyright) 2008.

The Panama gateway region has been widely used to document and model patterns of evolution in a well-constrained geologic setup. The changes brought about by the slow closure of the gateway were dramatic to say the least and led to the formation of two strikingly different realms, the Caribbean Sea and the eastern Pacific Ocean. Whereas the eastern Pacific has a strong tidal regime, high planktonic biomass, primary productivity and intense predation levels, the Caribbean became oligotrophic, with increased surface water temperature, salinity and carbonate deposition, as well as extensive reef and shallow-water seagrass communities. These changes were accompanied by the increased isolation and divergence of species across the developing barrier and shifts in diversity due to differential extinction and origination rates. The study of past and present day communities and their relationships in such a well documented setup can be used for a better understanding of the relation between adaptation, selection and changing environmental parameters. This paper reviews results documenting the events that shaped the shallow water marine biota during the last 15 million years during the gradual rise of the Central American land bridge. These data show how important it is to know the context in which they first evolved to properly understand modern species ecology and adaptation.
