On March 17, 2009, a surtseyan eruption occurred around Hunga Ha'apai Island, Tonga. A series of observations from the high-spatial resolution Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), and the high-temporal resolution Moderate Resolution Imaging Spectroradiometer (MODIS), was used to estimate the magnitude, location, start time, and duration of the eruption, and measure the evolving characteristics of the new Hunga Ha'apai Island. The eruption start time was estimated to be between 01:50 and 11:10 local time, on March 17, 2009 (i.e., between 12:50 and 22:10 UTC, March 16). The initial explosive phase lasted 3–5 days and consisted of multiple steam and tephra explosions from two distinct vent sources, one on the northwest side, and another about 100 m off the south shore of the pre-existing island. The eruption plume reached 4.0 to 7.6 km altitude above sea level, and tephra added new land around each of the vents, initially tripling the area of the pre-existing island. The next phase of steaming from newly formed crater lakes around the vents lasted a few days. Three warm crater lakes formed initially, but disappeared with time as the shoreline eroded. After ~ 2 months, vegetation that was initially buried by tephra was recovering; after ~ 10 months, the size of the island had eroded down to ~ twice that of the pre-existing island, and the one remaining crater lake had a temperature of ~ 68 ± 17 °C. The volume of erupted material was estimated to be ~ 0.0176 km3 and the volcanic explosivity index (VEI) was estimated to be VEI = 2.

Factor analysis-based habitat suitability models describe the ecological niche of a species and identify locations where these conditions occur on the landscape using existing occurrence data. We used factor analyses to assess the suitability of habitats for Thamnophis gigas (Giant Gartersnake), a rare, threatened species endemic to the Central Valley of California, USA, and to map the locations of habitat suitable for T. gigas in the Sacramento Valley. Factor analyses indicated that the niche of T. gigas is composed of sites near rice agriculture with low stream densities. Sites with high canal densities and near wetlands also appeared suitable, but results for these variables were sensitive to potential sampling bias. In the Sacramento Valley, suitable habitats occur primarily in the central portion of the valley floor. Based upon the results of the factor analyses, recovery planning for T. gigas will require an on-the-ground assessment of the current distribution and abundance of T. gigas, maintaining the few remaining natural wetlands and the practice of rice agriculture in the Sacramento Valley, and studying the effects of agricultural practices and land use changes on populations of T. gigas. ?? 2010 by the American Society of Ichthyologists and Herpetologists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Copeia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1643/CE-09-199","issn":"00458511","usgsCitation":"Halstead, B., Wylie, G., and Casazza, M.L., 2010, Habitat suitability and conservation of the Giant Gartersnake (Thamnophis gigas) in the Sacramento Valley of California: Copeia, no. 4, p. 591-599, https://doi.org/10.1643/CE-09-199.","startPage":"591","endPage":"599","numberOfPages":"9","costCenters":[],"links":[{"id":246434,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218427,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1643/CE-09-199"}],"issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2f2ce4b0c8380cd5cb5a","contributors":{"authors":[{"text":"Halstead, B.J.","contributorId":42045,"corporation":false,"usgs":true,"family":"Halstead","given":"B.J.","email":"","affiliations":[],"preferred":false,"id":455013,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wylie, G.D.","contributorId":68238,"corporation":false,"usgs":true,"family":"Wylie","given":"G.D.","email":"","affiliations":[],"preferred":false,"id":455014,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Casazza, Michael L. 0000-0002-5636-735X mike_casazza@usgs.gov","orcid":"https://orcid.org/0000-0002-5636-735X","contributorId":2091,"corporation":false,"usgs":true,"family":"Casazza","given":"Michael","email":"mike_casazza@usgs.gov","middleInitial":"L.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":455012,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70194390,"text":"70194390 - 2010 - Occurrence of West Nile virus infection in raptors at the Salton Sea, California","interactions":[],"lastModifiedDate":"2017-11-27T14:54:49","indexId":"70194390","displayToPublicDate":"2010-01-01T00:00:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2507,"text":"Journal of Wildlife Diseases","active":true,"publicationSubtype":{"id":10}},"title":"Occurrence of West Nile virus infection in raptors at the Salton Sea, California","docAbstract":"We investigated the prevalence of West Nile virus (WNV)-neutralizing antibodies and infectious virus, and the occurrence of overwinter transmission in two raptor species during January and March 2006 at the Salton Sea, Imperial County, California.

As part of the National Gap Analysis Program, we specifically examined physical site features at randomly selected sample locations in the Southwestern U.S. to assess degree of concordance with predicted features used in modeling vertebrate habitat distribution. Our analysis considered hypotheses about relative accuracy with respect to 30 vertebrate species selected to represent the spectrum of habitat generalist to specialist and categorization of site by relative degree of conservation emphasis accorded to the site. Overall comparison of 19 variables observed at 382 sample sites indicated ???60% concordance for 12 variables. Directly measured or observed variables (slope, soil composition, rock outcrop) generally displayed high concordance, while variables that required judgments regarding descriptive categories (aspect, ecological system, landform) were less concordant. There were no differences detected in concordance among taxa groups, degree of specialization or generalization of selected taxa, or land conservation categorization of sample sites with respect to all sites. We found no support for the hypothesis that accuracy of habitat models is inversely related to degree of taxa specialization when model features for a habitat specialist could be more difficult to represent spatially. Likewise, we did not find support for the hypothesis that physical features will be predicted with higher accuracy on lands with greater dedication to biodiversity conservation than on other lands because of relative differences regarding available information. Accuracy generally was similar (>60%) to that observed for land cover mapping at the ecological system level. These patterns demonstrate resilience of gap analysis deductive model processes to the type of remotely sensed or interpreted data used in habitat feature predictions. ?? 2010 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Modelling","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.ecolmodel.2010.08.034","issn":"03043800","usgsCitation":"Boykin, K., Thompson, B., and Propeck-Gray, S., 2010, Accuracy of gap analysis habitat models in predicting physical features for wildlife-habitat associations in the southwest U.S.: Ecological Modelling, v. 221, no. 23, p. 2769-2775, https://doi.org/10.1016/j.ecolmodel.2010.08.034.","startPage":"2769","endPage":"2775","numberOfPages":"7","costCenters":[],"links":[{"id":246205,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218216,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.ecolmodel.2010.08.034"}],"volume":"221","issue":"23","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e68ae4b0c8380cd474a6","contributors":{"authors":[{"text":"Boykin, K.G.","contributorId":62797,"corporation":false,"usgs":true,"family":"Boykin","given":"K.G.","email":"","affiliations":[],"preferred":false,"id":454498,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thompson, B.C.","contributorId":102433,"corporation":false,"usgs":true,"family":"Thompson","given":"B.C.","email":"","affiliations":[],"preferred":false,"id":454499,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Propeck-Gray, S.","contributorId":24609,"corporation":false,"usgs":true,"family":"Propeck-Gray","given":"S.","email":"","affiliations":[],"preferred":false,"id":454497,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70036449,"text":"70036449 - 2010 - Mercury and methylmercury dynamics in a coastal plain watershed, New Jersey, USA","interactions":[],"lastModifiedDate":"2012-03-12T17:22:03","indexId":"70036449","displayToPublicDate":"2010-01-01T00:00:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3728,"text":"Water, Air, & Soil Pollution","onlineIssn":"1573-2932","printIssn":"0049-6979","active":true,"publicationSubtype":{"id":10}},"title":"Mercury and methylmercury dynamics in a coastal plain watershed, New Jersey, USA","docAbstract":"The upper Great Egg Harbor River watershed in New Jersey's Coastal Plain is urbanized but extensive freshwater wetlands are present downstream. In 2006-2007, studies to assess levels of total mercury (THg) found concentrations in unfiltered streamwater to range as high as 187 ng/L in urbanized areas. THg concentrations were <20 ng/L in streamwater in forested/wetlands areas where both THg and dissolved organic carbon concentrations tended to increase while pH and concentrations of dissolved oxygen and nitrate decreased with flushing of soils after rain. Most of the river's flow comes from groundwater seepage; unfiltered groundwater samples contained up to 177 ng/L of THg in urban areas where there is a history of well water with THg that exceeds the drinking water standard (2,000 ng/L). THg concentrations were lower (<25 ng/L) in unfiltered groundwater from downstream wetland areas. In addition to higher THg concentrations (mostly particulate), concentrations of chloride were higher in streamwater and groundwater from urban areas than in those from downstream wetland areas. Methylmercury (MeHg) concentrations in unfiltered streamwater ranged from 0.17 ng/L at a forest/wetlands site to 2.94 ng/L at an urban site. The percentage of THg present as MeHg increased as the percentage of forest + wetlands increased, but also was high in some urban areas. MeHg was detected only in groundwater <1 m below the water/sediment interface. Atmospheric deposition is presumed to be the main source of Hg to the wetlands and also may be a source to groundwater, where wastewater inputs in urban areas are hypothesized to mobilize Hg deposited to soils. ?? 2010 US Government.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Water, Air, and Soil Pollution","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s11270-010-0340-1","issn":"00496979","usgsCitation":"Barringer, J.L., Riskin, M., Szabo, Z., Reilly, P., Rosman, R., Bonin, J., Fischer, J., and Heckathorn, H., 2010, Mercury and methylmercury dynamics in a coastal plain watershed, New Jersey, USA: Water, Air, & Soil Pollution, v. 212, no. 1-4, p. 251-273, https://doi.org/10.1007/s11270-010-0340-1.","startPage":"251","endPage":"273","numberOfPages":"23","costCenters":[],"links":[{"id":246288,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218289,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s11270-010-0340-1"}],"volume":"212","issue":"1-4","noUsgsAuthors":false,"publicationDate":"2010-02-24","publicationStatus":"PW","scienceBaseUri":"505a53dbe4b0c8380cd6cd71","contributors":{"authors":[{"text":"Barringer, J.

In this paper we give a synthesis of the geology of the Antongil Craton and present previously published and new geochemical and U-Pb zircon analyses to provide an event history for its evolution.The oldest rocks in the Antongil Craton form a nucleus of tonalitic gneiss, characteristic of Palaeo-Mesoarchaean cratons globally, including phases dated between 3320 ?? 14. Ma to 3231 ?? 6. Ma and 3187 ?? 2. Ma to 3154 ?? 5. Ma. A series of mafic dykes was intruded into the Mesoarchaean tonalites and a sedimentary succession was deposited on the craton prior to pervasive deformation and migmatisation of the region. The age of deposition of the metasediments has been constrained from a volcanic horizon to around 3178 ?? 2. Ma and subject to migmatisation at around 2597 ?? 49. Ma. A subsequent magmatic episode generated voluminous, weakly foliated granitic rocks, that also included additions from both reworked older crustal material and younger source components. An earlier granodiorite-dominated assemblage, dated between 2570 ?? 18. Ma and 2542 ?? 5. Ma, is largely exposed in xenoliths and more continuously in the northern part of the craton, while a later monzogranite-dominated phase, dated between 2531 ?? 13. Ma and 2513 ?? 0.4. Ma is more widely developed. Together these record the stabilisation of the craton, attested to by the intrusion of a younger dyke swarm, the age of which is constrained by a sample of metagabbro dated at 2147 ?? 6. Ma, providing the first evidence for Palaeoproterozoic rocks from the Antongil Craton.The youngest events recorded in the isotopic record of the Antongil Craton are reflected in metamorphism, neocrystallisation and Pb-loss at 792 ?? 130. Ma to 763 ?? 13. Ma and 553 ?? 68. Ma. These events are interpreted as being the only manifestation of the Pan-African orogeny seen in the craton, which led to the assembly of the tectonic blocks that comprise the island. ?? 2010 NERC.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Precambrian Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.precamres.2010.07.006","issn":"03019268","usgsCitation":"Schofield, D.I., Thomas, R., Goodenough, K.M., De Waele, B., Pitfield, P., Key, R.M., Bauer, W., Walsh, G., Lidke, D., Ralison, A., Rabarimanana, M., Rafahatelo, J.M., and Randriamananjara, T., 2010, Geological evolution of the Antongil Craton, NE Madagascar: Precambrian Research, v. 182, no. 3, p. 187-203, https://doi.org/10.1016/j.precamres.2010.07.006.","startPage":"187","endPage":"203","numberOfPages":"17","costCenters":[],"links":[{"id":490610,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://www.sciencedirect.com/science/journal/03019268","text":"External Repository"},{"id":218188,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.precamres.2010.07.006"},{"id":246174,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"182","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a225fe4b0c8380cd56faa","contributors":{"authors":[{"text":"Schofield, D.

These faults are part of a system of conjugate faults that accommodate the internal deformation of Panam?? resulting from the ongoing collision of Central and South America. There have been at least three surface ruptures on the Lim??n fault in the past 950-1400 years, with the most recent during the past 365 years. Displacement in this young event is at least 1.2 m (based on trenching) and may be 1.6-2 m (based on small channel offsets). Awell-preserved 4.2 m offset suggests that the penultimate event also sustained significant displacement. The Holocene slip rate has averaged about 6 mm=yr, based on a 30-m offset terrace riser incised into a 5-ka abandoned channel. The Pedro Miguel fault has sustained three surface ruptures in the past 1600 years, the most recent being the 2 May 1621 earthquake that partially destroyed Panam?? Viejo. At least 2.1 m of slip occurred in this event near the Canal, with geomorphic offsets suggesting 2.5-3 m. The historic Camino de Cruces is offset 2.8 m, indicating multimeter displacement over at least 20 km of fault length. Channel offsets of 100-400 m, together with a climate-induced incision model, suggest a Late Quaternary slip rate of about 5 mm=yr, which is consistent with the paleoseismic results. Comparison of the timing of surface ruptures between the Lim??n and Pedro Miguel faults suggests that large earthquakes may rupture both faults with 2-3 m of displacement for over 40 km, such as is likely in earthquakes in the M 7 range. Altogether, our observations indicate that the Lim??n and Pedro Miguel faults represent a significant seismic hazard to central Panam?? and, specifically, to the Canal and Panam?? City.","largerWorkTitle":"Seismological Society of America","language":"English","doi":"10.1785/0120090342","issn":"00371106","usgsCitation":"Rockwell, T., Gath, E., Gonzalez, T., Madden, C., Verdugo,

the microscopic morphology of tissue healing in Montipora capitata. Fragments from two healthy coral colonies were traumatized by scraping tissue and skeleton and monitored in flow-through seawater tables every 2-4. days for 40. days for gross and cellular changes.

In the US Great Plains, EDCs are impacting streams and rivers and may be causing adverse reproductive effects. To examine how estrogenic EDCs might affect reproductive success of plains fishes, we experimentally exposed male red shiners (Cyprinella lutrensis) to exogenous 17b-estradiol. We characterized the effects of estradiol on male gonadal histology and secondary sexual characteristics, determined whether exposure reduced reproductive success, and examined the effects of depuration. Adults were exposed to a mean concentration of 70 ng L-1 estradiol, a solvent control, or a water control for at least 83 days. Male exposure to estradiol resulted in elevated plasma vitellogenin concentrations, changes in spermatogenesis, reduced mating coloration and tubercles, altered mating behaviors, and reduced reproductive success with no viable progeny produced. Reproductive endpoints improved upon depuration (28 days). Exposure to estradiol had significant adverse effects on red shiners, indicating that wild populations may face developmental and reproductive difficulties if they are chronically exposed to estradiol.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Fisheries and Aquatic Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/F10-092","issn":"0706652X","usgsCitation":"McGree, M., Winkelman, D., Vieira, N., and Vajda, A., 2010, Reproductive failure of the red shiner (Cyprinella lutrensis) after exposure to an exogenous estrogen: Canadian Journal of Fisheries and Aquatic Sciences, v. 67, no. 11, p. 1730-1743, https://doi.org/10.1139/F10-092.","startPage":"1730","endPage":"1743","numberOfPages":"14","costCenters":[],"links":[{"id":218266,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/F10-092"},{"id":246262,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"67","issue":"11","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aa8d0e4b0c8380cd85ab7","contributors":{"authors":[{"text":"McGree, M.M.","contributorId":85018,"corporation":false,"usgs":true,"family":"McGree","given":"M.M.","email":"","affiliations":[],"preferred":false,"id":456490,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Winkelman, D.L. 0000-0002-5247-0114","orcid":"https://orcid.org/0000-0002-5247-0114","contributorId":48739,"corporation":false,"usgs":true,"family":"Winkelman","given":"D.L.","affiliations":[],"preferred":false,"id":456488,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Vieira, N.K.M.","contributorId":71034,"corporation":false,"usgs":true,"family":"Vieira","given":"N.K.M.","email":"","affiliations":[],"preferred":false,"id":456489,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Vajda, A.M.","contributorId":35961,"corporation":false,"usgs":true,"family":"Vajda","given":"A.M.","affiliations":[],"preferred":false,"id":456487,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70036508,"text":"70036508 - 2010 - The three scales of submarine groundwater flow and discharge across passive continental margins","interactions":[],"lastModifiedDate":"2017-08-30T14:24:04","indexId":"70036508","displayToPublicDate":"2010-01-01T00:00:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2309,"text":"Journal of Geology","active":true,"publicationSubtype":{"id":10}},"title":"The three scales of submarine groundwater flow and discharge across passive continental margins","docAbstract":"Increased study of submarine groundwater systems in recent years has provided a wealth of new data and techniques, but some ambiguity has been introduced by insufficient distinguishing of the relevant spatial scales of the phenomena studied.

Consistency in the seasonal phasing of terrestrial plant activity provides a relatively low-noise background from which phenological shifts can be detected and attributed to climate change. Here, we ask whether phytoplankton biomass also fluctuates over a consistent annual cycle in lake, estuarine-coastal and ocean ecosystems and whether there is a characteristic phenology of phytoplankton as a consistent phase and amplitude of variability. We compiled 125 time series of phytoplankton biomass (chloro-phyll a concentration) from temperate and subtropical zones and used wavelet analysis to extract their dominant periods of variability and the recurrence strength at those periods. Fewer than half (48%) of the series had a dominant 12-month period of variability, commonly expressed as the canonical spring-bloom pattern. About 20 per cent had a dominant six-month period of variability, commonly expressed as the spring and autumn or winter and summer blooms of temperate lakes and oceans. These annual patterns varied in recurrence strength across sites, and did not persist over the full series duration at some sites. About a third of the series had no component of variability at either the six-or 12-month period, reflecting a series of irregular pulses of biomass. These findings show that there is high variability of annual phytoplankton cycles across ecosystems, and that climate-driven annual cycles can be obscured by other drivers of population variability, including human disturbance, aperiodic weather events and strong trophic coupling between phytoplankton and their consumers. Regulation of phytoplankton biomass by multiple processes operating at multiple time scales adds complexity to the challenge of detecting climate-driven trends in aquatic ecosystems where the noise to signal ratio is high.

These shells are composed largely of aragonite (CaCO3) and potentially could be used for radiocarbon dating, but they must meet two criteria before their 14C ages can be considered to be reliable: (1) when gastropods are alive, the 14C activity of their shells must be in equilibrium with the 14C activity of the atmosphere, and (2) after burial, their shells must behave as closed systems with respect to carbon. To evaluate the first criterion, we conducted a comprehensive examination of the 14C content of the most common small terrestrial gastropods in North America, including 247 AMS measurements of modern shell material (3749 individual shells) from 46 different species. The modern gastropods that we analyzed were all collected from habitats on carbonate terrain and, therefore, the data presented here represent worst-case scenarios. In sum, ~78% of the shell aliquots that we analyzed did not contain dead carbon from limestone or other carbonate rocks even though it was readily available at all sites, 12% of the aliquots contained between 5 and 10% dead carbon, and a few (3% of the total) contained more than 10%. These results are significantly lower than the 20-30% dead carbon that has been reported previously for larger taxa living in carbonate terrain. For the second criterion, we report a case study from the American Midwest in which we analyzed fossil shells of small terrestrial gastropods (7 taxa; 18 AMS measurements; 173 individual shells) recovered from late-Pleistocene sediments. The fossil shells yielded 14C ages that were statistically indistinguishable from 14C ages of well-preserved plant macrofossils from the same stratum. Although just one site, these results suggest that small terrestrial gastropod shells may behave as closed systems with respect to carbon over geologic timescales. More work on this subject is needed, but if our case study site is representative of other sites, then fossil shells of some small terrestrial gastropods, including at least five common genera, Catinella, Columella, Discus, Gastrocopta, and Succinea, should yield reliable 14C ages, regardless of the local geologic substrate. ?? 2010.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Quaternary Geochronology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.quageo.2010.01.001","issn":"18711014","usgsCitation":"Pigati, J., Rech, J., and Nekola, J., 2010, Radiocarbon dating of small terrestrial gastropod shells in North America: Quaternary Geochronology, v. 5, no. 5, p. 519-532, https://doi.org/10.1016/j.quageo.2010.01.001.","startPage":"519","endPage":"532","numberOfPages":"14","costCenters":[],"links":[{"id":246289,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218290,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.quageo.2010.01.001"}],"volume":"5","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a93e1e4b0c8380cd810a7","contributors":{"authors":[{"text":"Pigati, J.S.","contributorId":80486,"corporation":false,"usgs":true,"family":"Pigati","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":456354,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rech, J.A.","contributorId":79659,"corporation":false,"usgs":true,"family":"Rech","given":"J.A.","affiliations":[],"preferred":false,"id":456353,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Nekola, J.C.","contributorId":83776,"corporation":false,"usgs":true,"family":"Nekola","given":"J.C.","affiliations":[],"preferred":false,"id":456355,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70194392,"text":"70194392 - 2010 - Nighttime aboveground movements by prairie dogs on colonies inhabited by black-footed ferrets","interactions":[],"lastModifiedDate":"2017-11-27T15:07:43","indexId":"70194392","displayToPublicDate":"2010-01-01T00:00:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3746,"text":"Western North American Naturalist","onlineIssn":"1944-8341","printIssn":"1527-0904","active":true,"publicationSubtype":{"id":10}},"title":"Nighttime aboveground movements by prairie dogs on colonies inhabited by black-footed ferrets","docAbstract":"We describe observations of black-tailed prairie dogs (Cynomys ludovicianus) emerging aboveground at night, apparently in response to wild-born and captive-born black-footed ferrets (Mustela nigripes) in South Dakota and New Mexico, respectively.

Molecular genetic data have more recently been used to assess these classifications and, in many cases, to redefine them. The recent practice of utilizing molecular genetic data to examine taxonomic questions has led some to suggest that molecular genetic methods are more appropriate than traditional methods for addressing taxonomic uncertainty and management units. We compared the North American Tetraoninae—which have been defined using plumage, morphology, and behavior—and considered the effects of redefinition using only neutral molecular genetic data (mitochondrial control region and cytochrome oxidase subunit 1). Using the criterion of reciprocal monophyly, we failed to recognize the five species whose mating system is highly polygynous, with males displaying on leks. In lek-breeding species, sexual selection can act to influence morphological and behavioral traits at a rate much faster than can be tracked genetically. Thus, we suggest that at least for lek-breeding species, it is important to recognize the possibility that morphological and behavioral changes may occur at an accelerated rate compared with the processes that led to reciprocal monophyly of putatively neutral genetic markers. Therefore, it is particularly important to consider the possible disconnect between such lines of evidence when making taxonomic revisions and definitions of management units.

Other than costly destructive harvest methods, no technique exists to rapidly and accurately measure above-ground perennial tissue for woody plants such as Vitis vinifera (common grape vine). Data collected from grapevine trunks and cordons were used to study the accuracy of wood volume derived from laser scanning as compared with volume derived from analog measurements. A set of 10 laser scan datasets were collected for each of 36 vines from which volume was calculated using combinations of two, three, four, six and 10 scans. Likewise, analog volume measurements were made by submerging the vine trunks and cordons in water and capturing the displaced water. A regression analysis examined the relationship between digital and non-digital techniques among the 36 vines and found that the standard error drops rapidly as additional scans are added to the volume calculation process and stabilizes at the four-view geometry with an average Pearson's product moment correlation coefficient of 0.93. Estimates of digital volumes are systematically greater than those of analog volumes and can be explained by the manner in which each technique interacts with the vine tissue. This laser scanning technique yields a highly linear relationship between vine volume and tissue mass revealing a new, rapid and non-destructive method to remotely measure standing biomass. This application shows promise for use in other ecosystems such as orchards and forests. ?? 2010 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Computers and Electronics in Agriculture","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.compag.2010.09.005","issn":"01681699","usgsCitation":"Keightley, K., and Bawden, G., 2010, 3D volumetric modeling of grapevine biomass using Tripod LiDAR: Computers and Electronics in Agriculture, v. 74, no. 2, p. 305-312, https://doi.org/10.1016/j.compag.2010.09.005.","startPage":"305","endPage":"312","numberOfPages":"8","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":246264,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218268,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.compag.2010.09.005"}],"volume":"74","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e25ce4b0c8380cd45af8","contributors":{"authors":[{"text":"Keightley, K.E.","contributorId":57310,"corporation":false,"usgs":true,"family":"Keightley","given":"K.E.","email":"","affiliations":[],"preferred":false,"id":456493,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bawden, G.W.","contributorId":61139,"corporation":false,"usgs":true,"family":"Bawden","given":"G.W.","email":"","affiliations":[],"preferred":false,"id":456494,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70197555,"text":"70197555 - 2010 - Pathology and distribution of sea turtles landed as bycatch in the Hawaii-based North Pacific pelagic longline fishery","interactions":[],"lastModifiedDate":"2018-06-11T15:55:06","indexId":"70197555","displayToPublicDate":"2010-01-01T00:00:00","publicationYear":"2010","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2507,"text":"Journal of Wildlife Diseases","active":true,"publicationSubtype":{"id":10}},"title":"Pathology and distribution of sea turtles landed as bycatch in the Hawaii-based North Pacific pelagic longline fishery","docAbstract":"We examined the gross and microscopic pathology and distribution of sea turtles that were landed as bycatch from the Hawaii, USA–based pelagic longline fishery and known to be forced submerged. Olive ridley turtles (Lepidochelys olivacea) composed the majority of animals examined, and hook-induced perforation of the esophagus was the most common gross lesion followed by perforation of oral structures (tongue, canthus) and of flippers. Gross pathology in the lungs suggestive of drowning was seen in 23 of 71 turtles. Considering only the external gross findings, the pathologist and the observer on board the longline vessel agreed on hook-induced lesions only 60% of the time thereby illustrating the limitations of depending on external examination alone to implicate hooking interactions or drowning as potential cause of sea turtle mortality. When comparing histology of drowned turtles to a control group of nondrowned turtles, the former had significantly more pulmonary edema, hemorrhage, and sloughed columnar epithelium. These microscopic changes may prove useful to diagnose suspected drowning in sea turtles where history of hooking or netting interactions is unknown.
