Here we use the General Ensemble biogeochemical Modeling System to simulate the terrestrial ecosystem carbon dynamics in the Jinsha watershed of China’s upper Yangtze basin from 1975 to 2000, based on unique combinations of spatial and temporal dynamics of major driving forces, such as climate, soil properties, nitrogen deposition, and land use and land cover changes. Our analysis demonstrates that the Jinsha watershed ecosystems acted as a carbon sink during the period of 1975–2000, with an average rate of 0.36 Mg/ha/yr, primarily resulting from regional climate variation and local land use and land cover change. Vegetation biomass accumulation accounted for 90.6% of the sink, while soil organic carbon loss before 1992 led to a lower net gain of carbon in the watershed, and after that soils became a small sink. Ecosystem carbon sink/source patterns showed a high degree of spatial heterogeneity. Carbon sinks were associated with forest areas without disturbances, whereas carbon sources were primarily caused by stand-replacing disturbances. It is critical to adequately represent the detailed fast-changing dynamics of land use activities in regional biogeochemical models to determine the spatial and temporal evolution of regional carbon sink/source patterns.","language":"English","publisher":"Springer","doi":"10.1007/s00267-009-9285-9","usgsCitation":"Zhao, S., Liu, S., Yin, R., Li, Z., Deng, Y., Tan, K., Deng, X., Rothstein, D., and Qi, J., 2010, Quantifying terrestrial ecosystem carbon dynamics in the Jinsha watershed, Upper Yangtze, China from 1975 to 2000: Environmental Management, v. 45, no. 3, p. 466-475, https://doi.org/10.1007/s00267-009-9285-9.","productDescription":"10 p.","startPage":"466","endPage":"475","ipdsId":"IP-011153","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":271686,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"China","otherGeospatial":"Jinsha watershed, Yangtze River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 97.36,21.62 ], [ 97.36,32.38 ], [ 104.08,32.38 ], [ 104.08,21.62 ], [ 97.36,21.62 ] ] ] } } ] }","volume":"45","issue":"3","noUsgsAuthors":false,"publicationDate":"2009-03-19","publicationStatus":"PW","scienceBaseUri":"5180e7ebe4b0df838b924d90","contributors":{"authors":[{"text":"Zhao, Shuqing","contributorId":9152,"corporation":false,"usgs":true,"family":"Zhao","given":"Shuqing","email":"","affiliations":[],"preferred":false,"id":473394,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Liu, Shuguang 0000-0002-6027-3479 sliu@usgs.gov","orcid":"https://orcid.org/0000-0002-6027-3479","contributorId":147403,"corporation":false,"usgs":true,"family":"Liu","given":"Shuguang","email":"sliu@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":true,"id":692785,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Yin, Runsheng","contributorId":150057,"corporation":false,"usgs":false,"family":"Yin","given":"Runsheng","email":"","affiliations":[{"id":17896,"text":"State Key Laboratory of Ore Deposit Geochemistry, Institute of Geochemistry, Chinese Academy of Sciences, Guiyang, China","active":true,"usgs":false}],"preferred":false,"id":692786,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Li, Zhengpeng","contributorId":80812,"corporation":false,"usgs":true,"family":"Li","given":"Zhengpeng","affiliations":[],"preferred":false,"id":692787,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Deng, Yulin","contributorId":191348,"corporation":false,"usgs":false,"family":"Deng","given":"Yulin","email":"","affiliations":[],"preferred":false,"id":692788,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Tan, Kun","contributorId":191349,"corporation":false,"usgs":false,"family":"Tan","given":"Kun","email":"","affiliations":[],"preferred":false,"id":692789,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Deng, Xiangzheng","contributorId":191350,"corporation":false,"usgs":false,"family":"Deng","given":"Xiangzheng","email":"","affiliations":[],"preferred":false,"id":692790,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Rothstein, David","contributorId":191351,"corporation":false,"usgs":false,"family":"Rothstein","given":"David","email":"","affiliations":[],"preferred":false,"id":692791,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Qi, Jiaguo","contributorId":191352,"corporation":false,"usgs":false,"family":"Qi","given":"Jiaguo","email":"","affiliations":[],"preferred":false,"id":692792,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

During the developmental phase of the pump station, a need was identified to better understand the larval drift characteristics of these endangered catostomids in order to reduce entrainment into the irrigation system. The spatial, seasonal, and diel distribution of drifting larvae was measured during the 2004 spawning season at two proposed sites on the Williamson River where the pump station could be located. Larval drift for both species coincided with the irrigation season making them subject to entrainment into the irrigation system. Drift occurred almost exclusively at night with larvae entering the drift at sunset and exiting the drift at sunrise. Nighttime larval densities were concentrated near the surface and at midchannel at both sites. Densities were generally greater on the side of mid-channel with greater flow. During early morning sampling we detected a general shift in larval drift from surface to subsurface drift. We also observed an increase in larval densities towards the shore opposite from the proposed pump station at the upper site whereas larval densities remained high at midchannel at the lower site. During daytime sampling, the few larvae that were collected were distributed throughout the water column at both pump sites. This study found that larvae drifting during all time periods were generally distributed further across the cross section, deeper in the water column, and closer to where the proposed water withdrawal structure would be built at the downstream site when compared to the upstream site. Recommendations were provided to locate the withdrawal facility at the upstream site and operate it in a manner such that larval entrainment would likely be minimized.","language":"English","publisher":"Springer","doi":"10.1007/s10641-010-9688-8","usgsCitation":"Ellsworth, C.M., Tyler, T.J., and VanderKooi, S., 2010, Using spatial, seasonal, and diel drift patterns of larval Lost River suckers Deltistes luxatus (Cypriniformes: Catostomidae) and shortnose suckers Chasmistes brevirostris (Cypriniformes: Catostomidae) to help identify a site for a water withdrawal structure on the Williamson River, Oregon: Environmental Biology of Fishes, v. 89, no. 1, p. 47-57, https://doi.org/10.1007/s10641-010-9688-8.","productDescription":"11 p.","startPage":"47","endPage":"57","ipdsId":"IP-015357","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":272295,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":272294,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10641-010-9688-8"}],"country":"United States","state":"Oregon","otherGeospatial":"Williamson River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -12.018333333333334,4.035833333333334 ], [ -12.018333333333334,0.0011111111111111111 ], [ -12.018333333333334,0.0011111111111111111 ], [ -12.018333333333334,4.035833333333334 ], [ -12.018333333333334,4.035833333333334 ] ] ] } } ] }","volume":"89","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-08-03","publicationStatus":"PW","scienceBaseUri":"51955850e4b0a933d82c4ccb","contributors":{"authors":[{"text":"Ellsworth, Craig M.","contributorId":14913,"corporation":false,"usgs":true,"family":"Ellsworth","given":"Craig","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":474037,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Tyler, Torrey J.","contributorId":91199,"corporation":false,"usgs":true,"family":"Tyler","given":"Torrey","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":474038,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"VanderKooi, Scott P.","contributorId":106584,"corporation":false,"usgs":true,"family":"VanderKooi","given":"Scott P.","affiliations":[],"preferred":false,"id":474039,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

A few existing models possess apparently significant radially variable viscosity structure in the shallow mantle (e.g., the upper 200 km), but the resolution of such variations is not clear. We use a geophysical inverse procedure to address the resolving power of inferred shallow mantle viscosity structure using postearthquake relaxation data. We apply this methodology to 9 years of GPS-constrained crustal motions after the 16 October 1999 M = 7.1 Hector Mine earthquake. After application of a differencing method to isolate the postearthquake signal from the “background” crustal velocity field, we find that surface velocities diminish from ∼20 mm/yr in the first few months to ≲2 mm/yr after 2 years. Viscoelastic relaxation of the mantle, with a time-dependent effective viscosity prescribed by a Burgers body, provides a good explanation for the postseismic crustal deformation, capturing both the spatial and temporal pattern. In the context of the Burgers body model (which involves a transient viscosity and steady state viscosity), a resolution analysis based on the singular value decomposition reveals that at most, two constraints on depth-dependent steady state mantle viscosity are provided by the present data set. Uppermost mantle viscosity (depth ≲ 60 km) is moderately resolved, but deeper viscosity structure is poorly resolved. The simplest model that explains the data better than that of uniform steady state mantle viscosity involves a linear gradient in logarithmic viscosity with depth, with a small increase from the Moho to 220 km depth. However, the viscosity increase is not statistically significant. This suggests that the depth-dependent steady state viscosity is not resolvably different from uniformity in the uppermost mantle.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research B: Solid Earth","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1029/2010JB007405","usgsCitation":"Pollitz, F., and Thatcher, W.R., 2010, On the resolution of shallow mantle viscosity structure using post-earthquake relaxation data:  Application to the 1999 Hector Mine, California, earthquake: Journal of Geophysical Research B: Solid Earth, 20 p., https://doi.org/10.1029/2010JB007405.","productDescription":"20 p.","numberOfPages":"20","additionalOnlineFiles":"N","ipdsId":"IP-019815","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":271680,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271679,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2010JB007405"}],"country":"United States","state":"California","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120.56,33.01 ], [ -120.56,37.00 ], [ -114.96,37.00 ], [ -114.96,33.01 ], [ -120.56,33.01 ] ] ] } } ] }","noUsgsAuthors":false,"publicationDate":"2010-10-15","publicationStatus":"PW","scienceBaseUri":"5180e7e9e4b0df838b924d80","contributors":{"authors":[{"text":"Pollitz, Fred F. fpollitz@usgs.gov","contributorId":2408,"corporation":false,"usgs":true,"family":"Pollitz","given":"Fred F.","email":"fpollitz@usgs.gov","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":false,"id":471643,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Thatcher, Wayne R. 0000-0001-6324-545X thatcher@usgs.gov","orcid":"https://orcid.org/0000-0001-6324-545X","contributorId":2599,"corporation":false,"usgs":true,"family":"Thatcher","given":"Wayne","email":"thatcher@usgs.gov","middleInitial":"R.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":true,"id":471644,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Using the Antarctic Dome C site (75°06′S, 123°21′E, elevation 3.2 km) for satellite radiometric calibration and validation (Cal/Val) is of great interest owing to its unique location and characteristics. The site surface is covered with uniformly distributed permanent snow, and the atmospheric effect is small and relatively constant. In this study, the long-term stability and spectral characteristics of this site are evaluated using well-calibrated satellite instruments such as the Moderate Resolution Imaging Spectroradiometer (MODIS) and Sea-viewing Wide Field-of-view Sensor (SeaWiFS). Preliminary results show that despite a few limitations, the site in general is stable in the long term, the bidirectional reflectance distribution function (BRDF) model works well, and the site is most suitable for the Cal/Val of reflective solar bands in the 0.4–1.0 µm range. It was found that for the past decade, the reflectivity change of the site is within 1.35% at 0.64 µm, and interannual variability is within 2%. The site is able to resolve calibration biases between instruments at a level of ~1%. The usefulness of the site is demonstrated by comparing observations from seven satellite instruments involving four space agencies, including OrbView-2–SeaWiFS, Terra–Aqua MODIS, Earth Observing 1 (EO-1) – Hyperion, Meteorological Operational satellite programme (MetOp) – Advanced Very High Resolution Radiometer (AVHRR), Envisat Medium Resolution Imaging Spectrometer (MERIS) – dvanced Along-Track Scanning Radiometer (AATSR), and Landsat 7 Enhanced Thematic Mapper Plus (ETM+). Dome C is a promising candidate site for climate quality calibration of satellite radiometers towards more consistent satellite measurements, as part of the framework for climate change detection and data quality assurance for the Global Earth Observation System of Systems (GEOSS).","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Remote Sensing","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Canadian Remote Sensing Society","doi":"10.5589/m10-075","issn":"07038992","usgsCitation":"Cao, C., Uprety, S., Xiong, J., Wu, A., Jing, P., Smith, D., Chander, G., Fox, N., and Ungar, S., 2010, Establishing the Antarctic Dome C community reference standard site towards consistent measurements from Earth observation satellites: Canadian Journal of Remote Sensing, v. 36, no. 5, p. 498-513, https://doi.org/10.5589/m10-075.","productDescription":"16 p.","startPage":"498","endPage":"513","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":218572,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.5589/m10-075"},{"id":246595,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"36","issue":"5","noUsgsAuthors":false,"publicationDate":"2014-06-02","publicationStatus":"PW","scienceBaseUri":"505a0a64e4b0c8380cd52338","contributors":{"authors":[{"text":"Cao, C.","contributorId":37944,"corporation":false,"usgs":true,"family":"Cao","given":"C.","email":"","affiliations":[],"preferred":false,"id":454680,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Uprety, S.","contributorId":65345,"corporation":false,"usgs":true,"family":"Uprety","given":"S.","affiliations":[],"preferred":false,"id":454686,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Xiong, J.","contributorId":58472,"corporation":false,"usgs":true,"family":"Xiong","given":"J.","email":"","affiliations":[],"preferred":false,"id":454684,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Wu, A.","contributorId":44019,"corporation":false,"usgs":true,"family":"Wu","given":"A.","email":"","affiliations":[],"preferred":false,"id":454682,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Jing, P.","contributorId":38859,"corporation":false,"usgs":true,"family":"Jing","given":"P.","email":"","affiliations":[],"preferred":false,"id":454681,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Smith, D.","contributorId":60978,"corporation":false,"usgs":true,"family":"Smith","given":"D.","affiliations":[],"preferred":false,"id":454685,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Chander, G.","contributorId":51449,"corporation":false,"usgs":true,"family":"Chander","given":"G.","affiliations":[],"preferred":false,"id":454683,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Fox, N.","contributorId":90905,"corporation":false,"usgs":true,"family":"Fox","given":"N.","email":"","affiliations":[],"preferred":false,"id":454687,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Ungar, S.","contributorId":15413,"corporation":false,"usgs":true,"family":"Ungar","given":"S.","affiliations":[],"preferred":false,"id":454679,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Seven regionally continuous high amplitude reflections are defined which bound six seismic stratigraphic units consisting of multiple regionally discontinuous depositional sequences and parasequence sets, and enable an understanding of the evolution of this margin. Data reveal the progressive eastward progradation and aggradation of the Quaternary shelf. The early Pleistocene inner shelf occurs at a depth of ca. 20-40 m beneath the western part of the modern estuarine system (Pamlico Sound). A mid- to outer shelf lowstand terrace (also early Pleistocene) with shelf sand ridge deposits comprising parasequence sets within a transgressive systems tract, occurs at a deeper level (ca. 45-70 m) beneath the modern barrier island system (the Outer Banks) and northern Pamlico Sound. Seismic and foraminiferal paleoenvironmental data from cores indicate the occurrence of lowstand strandplain shoreline deposits on the early to middle Pleistocene shelf. Middle to late Pleistocene deposits occur above a prominent unconformity and marine flooding surface that truncates underlying units, and contain numerous filled fluvial valleys that are incised into the early and middle Pleistocene deposits. The stratigraphic framework suggests margin progradation and aggradation modified by an increase in the magnitude of sea-level fluctuations during the middle to late Pleistocene, expressed as falling stage, lowstand, transgressive and highstand systems tracts. Thick stratigraphic sequences occur within the middle Pleistocene section, suggesting the occurrence of high capacity fluvial point sources debouching into the area from the west and north. Furthermore, the antecedent topography plays a significant role in the evolution of the geomorphology and stratigraphy of this marginal system. ?? 2009 Elsevier B.V.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Marine Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.margeo.2009.10.007","issn":"00253227","usgsCitation":"Mallinson, D.J., Culver, S., Riggs, S., Thieler, E., Foster, D., Wehmiller, J., Farrell, K., and Pierson, J., 2010, Regional seismic stratigraphy and controls on the Quaternary evolution of the Cape Hatteras region of the Atlantic passive margin, USA: Marine Geology, v. 268, no. 1-4, p. 16-33, https://doi.org/10.1016/j.margeo.2009.10.007.","productDescription":"18 p.","startPage":"16","endPage":"33","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":244642,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216756,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.margeo.2009.10.007"}],"volume":"268","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a559e4b0e8fec6cdbe0a","contributors":{"authors":[{"text":"Mallinson, D.

Of colonies of black-tailed prairie dogs in our study area, >80 were on slopes of playa lakes; thus, we used sites of colonies and non-colonies that were on slopes of playa lakes. We trapped small mammals on 29 pairs of sites. Overall abundance did not differ between types of sites, but some taxa exhibited associations with colonies (Onychomys leucogaster) or non-colonies (Chaetodipus hispidus, Reithrodontomys, Sigmodon hispidus). Diversity and evenness of small mammals did not differ between colonies and non-colonies in 2002, but were higher on non-colonies in 2003. Although we may not have detected some rare or infrequently occurring species, our data reveal differences in diversity and evenness of more common species among the types of sites. Prairie dogs are touted as a keystone species with their colonies associated with a greater faunal diversity than adjacent lands. Our findings contradict several studies reporting greater diversity and abundance of small mammals at colonies of prairie dogs. We suggest that additional research across a wider landscape and incorporating landscape variables beyond the immediate trapping plot may further elucidate interspecific associations between black-tailed prairie dogs and species of small rodents.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Southwestern Naturalist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1894/CLG-23.1","issn":"00384909","usgsCitation":"Pruett, A., Boal, C.W., Wallace, M., Whitlaw, H.A., and Ray, J., 2010, Small mammals associated with colonies of black-tailed prairie dogs (Cynomys ludovicianus) in the Southern High Plains: Southwestern Naturalist, v. 55, no. 1, p. 50-56, https://doi.org/10.1894/CLG-23.1.","startPage":"50","endPage":"56","numberOfPages":"7","costCenters":[],"links":[{"id":244960,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":217049,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1894/CLG-23.1"}],"volume":"55","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b9188e4b08c986b31996c","contributors":{"authors":[{"text":"Pruett, A.L.","contributorId":18606,"corporation":false,"usgs":true,"family":"Pruett","given":"A.L.","email":"","affiliations":[],"preferred":false,"id":459594,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Boal, C.

Sticky traps are commonly used to passively sample invertebrates, but catch rates may vary diurnally or in response to weather. We examined diurnal variation in catch rates of invertebrates using an experiment on reservoir shoreline and riverine sandbar habitats of the Upper Missouri River in 2006 and 2008. Highest catch rates of large invertebrates (&gt;3 mm) on dry sand habitats occurred during 08:00-11:00 Central Daylight Time (CDT) on the reservoir and 08:00-14:00 CDT on the river. On wet sand habitats, catch rates were lowest during 17:00-20:00 on both the reservoir and the river. Catch rates decreased 24% for every 10 kph increase in wind. Sticky traps deployed continuously for 12 h or more had lower catch rates than four consecutive-composited 3-hour deployments, suggesting that trap effectiveness declined for &gt;3-hour deployments. Thus, if sticky traps are used to index plover forage abundance without controlling for time of day and wind speed, data may be highly variable or estimates could be

Documentation of progress of this restoration effort is needed. A study was conducted to examine water quality in the Choptank River estuary, a tributary of the Chesapeake Bay that since 1998 has been classified as impaired waters under the Federal Clean Water Act. Multiple water quality parameters (salinity, temperature, dissolved oxygen, chlorophyll a) and analyte concentrations (nutrients, herbicide and herbicide degradation products, arsenic, and copper) were measured at seven sampling stations in the Choptank River estuary. Samples were collected under base flow conditions in the basin on thirteen dates between March 2005 and April 2008. As commonly observed, results indicate that agriculture is a primary source of nitrate in the estuary and that both agriculture and wastewater treatment plants are important sources of phosphorus. Concentrations of copper in the lower estuary consistently exceeded both chronic and acute water quality criteria, possibly due to use of copper in antifouling boat paint. Concentrations of copper in the upstream watersheds were low, indicating that agriculture is not a significant source of copper loading to the estuary. Concentrations of herbicides (atrazine, simazine, and metolachlor) peaked during early-summer, indicating a rapid surface-transport delivery pathway from agricultural areas, while their degradation products (CIAT, CEAT, MESA, and MOA) appeared to be delivered via groundwater transport. Some in-river processing of CEAT occurred, whereas MESA was conservative. Observed concentrations of herbicide residues did not approach established levels of concern for aquatic organisms. Results of this study highlight the importance of continued implementation of best management practices to improve water quality in the estuary. This work provides a baseline against which to compare future changes in water quality and may be used to design future monitoring programs needed to assess restoration strategy efficacy.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science of the Total Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.scitotenv.2010.01.006","issn":"00489697","usgsCitation":"Whitall, D., Hively, W., Leight, A., Hapeman, C., McConnell, L., Fisher, T., Rice, C., Codling, E., McCarty, G., Sadeghi, A., Gustafson, A., and Bialek, K., 2010, Pollutant fate and spatio-temporal variability in the choptank river estuary: Factors influencing water quality: Science of the Total Environment, v. 408, no. 9, p. 2096-2108, https://doi.org/10.1016/j.scitotenv.2010.01.006.","startPage":"2096","endPage":"2108","numberOfPages":"13","costCenters":[],"links":[{"id":217023,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.scitotenv.2010.01.006"},{"id":244933,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"408","issue":"9","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a7cdee4b0c8380cd79c14","contributors":{"authors":[{"text":"Whitall, D.","contributorId":66973,"corporation":false,"usgs":true,"family":"Whitall","given":"D.","email":"","affiliations":[],"preferred":false,"id":459883,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hively, W.D.","contributorId":78996,"corporation":false,"usgs":true,"family":"Hively","given":"W.D.","affiliations":[],"preferred":false,"id":459886,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Leight, A.K.","contributorId":6732,"corporation":false,"usgs":true,"family":"Leight","given":"A.K.","email":"","affiliations":[],"preferred":false,"id":459876,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hapeman, C.J.","contributorId":40481,"corporation":false,"usgs":true,"family":"Hapeman","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":459881,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"McConnell, L.L.","contributorId":53344,"corporation":false,"usgs":true,"family":"McConnell","given":"L.L.","email":"","affiliations":[],"preferred":false,"id":459882,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Fisher, T.","contributorId":38854,"corporation":false,"usgs":true,"family":"Fisher","given":"T.","email":"","affiliations":[],"preferred":false,"id":459880,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Rice, C.P.","contributorId":81065,"corporation":false,"usgs":true,"family":"Rice","given":"C.P.","email":"","affiliations":[],"preferred":false,"id":459887,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Codling, E.","contributorId":33592,"corporation":false,"usgs":true,"family":"Codling","given":"E.","affiliations":[],"preferred":false,"id":459879,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"McCarty, G.W.","contributorId":24533,"corporation":false,"usgs":true,"family":"McCarty","given":"G.W.","email":"","affiliations":[],"preferred":false,"id":459878,"contributorType":{"id":1,"text":"Authors"},"rank":9},{"text":"Sadeghi, A.M.","contributorId":72268,"corporation":false,"usgs":true,"family":"Sadeghi","given":"A.M.","affiliations":[],"preferred":false,"id":459885,"contributorType":{"id":1,"text":"Authors"},"rank":10},{"text":"Gustafson, A.","contributorId":21834,"corporation":false,"usgs":true,"family":"Gustafson","given":"A.","email":"","affiliations":[],"preferred":false,"id":459877,"contributorType":{"id":1,"text":"Authors"},"rank":11},{"text":"Bialek, K.","contributorId":68014,"corporation":false,"usgs":true,"family":"Bialek","given":"K.","affiliations":[],"preferred":false,"id":459884,"contributorType":{"id":1,"text":"Authors"},"rank":12}]}}

The National Land Cover Data Set for 2001 was produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium. The MRLC Consortium is a partnership of Federal agencies (www.mrlc.gov), consisting of the U.S. Geological Survey (USGS), the National Oceanic and Atmospheric Administration (NOAA), the U.S. Environmental Protection Agency (USEPA), the U.S. Department of Agriculture (USDA), the U.S. Forest Service (USFS), the National Park Service (NPS), the U.S. Fish and Wildlife Service (USFWS), the Bureau of Land Management (BLM), and the USDA Natural Resources Conservation Service (NRCS). One of the primary goals of the project is to generate a current, consistent, seamless, and accurate National Land Cover Database (NLCD) circa 2001 for the United States at medium spatial resolution. For a detailed definition and discussion on MRLC and the NLCD 2001 products, refer to Homer and others (2004) and http://www.mrlc.gov/mrlc2k.asp.. The NLCD 2001 was created by partitioning the United States into mapping-zones. A total of 68 mapping-zones browse graphic: nlcd01-mappingzones.jpg were delineated within the conterminous United States based on ecoregion and geographical characteristics, edge-matching features, and the size requirement of Landsat mosaics.

Reproducing populations of&nbsp;<i>L. rimosus</i>&nbsp;now occur only in the Clinch, Duck and Powell rivers, as the species is considered extirpated from the remaining portions of its range in the Tennessee River drainage. Females are long-term winter brooders, typically gravid from Oct. to May. Glochidia are contained in the outer gills and are released in association with a mantle-lure that resembles a small freshwater snail. Estimated fecundity, based on 8 gravid females collected from the Clinch and Duck rivers, ranged from 4132 to 58,700 glochidia/mussel. Seven fish species were tested for suitability as hosts for glochidia, and five darter species were confirmed through induced infestations:&nbsp;<i>Etheostoma blennioides</i>,&nbsp;<i>E. camurum</i>,&nbsp;<i>E. rufilineatum</i>,&nbsp;<i>E. simoterum</i>&nbsp;and&nbsp;<i>E. zonale</i>. Ages of&nbsp;<i>L. rimosus</i>&nbsp;shells were determined by thin-sectioning and ranged from 3 to 15&nbsp;y in both rivers. Shell growth was higher and maximum size greater in males than females in both rivers. Shell growth was greatest in the Duck River. Densities of&nbsp;<i>L. rimosus</i>&nbsp;in the Clinch River were maintained at seemingly stable but low levels ranging from 0.07 to 0.27&nbsp;m<sup>&minus;2</sup>&nbsp;from 2004&ndash;2007, and in the Duck River at similar but higher levels ranging from 0.6 to 1.0&nbsp;m<sup>&minus;2</sup>&nbsp;from 2004&ndash;2006.

These soils were chosen because of their differing chemical and physical properties, i.e., an organic-rich (43–46% by mass) volcanic ash-derived soil from the island of Hawaii, and a red, iron (22–29% by mass), aluminum (29–45% by mass), and clay-rich (68–76% by mass) volcanic soil from the island of Oahu. A third agricultural soil, an organic- (13% by mass) and quartz-rich (40% by mass) soil from Illinois, was included for reference. In 10-cm long flow-through columns, oocysts and microspheres advecting through the red volcanic soil were almost completely (98% and 99%) immobilized. The modest breakthrough resulted from preferential flow-path structure inadvertently created by soil-particle aggregation during the re-wetting process. Although a high (99%) removal of oocysts and microsphere within the volcanic ash soil occurred initially, further examination revealed that transport was merely retarded because of highly reversible interactions with grain surfaces. Judging from the slope of the substantive and protracted tail of the breakthrough curve for the 1.8-μm microspheres, almost all (&gt;99%) predictably would be recovered within ∼4000 pore volumes.

Systematic mineralogic and chemical examination of a suite of 32 natural stoichiometric jarosite and natrojarosite samples from diverse supergene and hydrothermal environments indicates that there is only limited solid solution between Na and K at low temperatures, which suggests the presence of a solvus in the jarosite-natrojarosite system at temperatures below about 140 C. The samples examined in this study consist of either end members or coexisting end-member pairs of jarosite and natrojarosite. Quantitative electron-probe microanalysis data for several natural hydrothermal samples show only end-member compositions for individual grains or zones, and no detectable alkali-site deficiencies, which indicates that there is no hydronium substitution within the analytical uncertainty of the method. In addition, there is no evidence of Fe deficiencies in the natural hydrothermal samples.

During July and August 2007, gill nets were fished in 6 to 8 m of water at two locations of known <i>Hemimysis</i> colonization in southeastern Lake Ontario to determine if fish that consume macroinvertebrates were beginning to include this new invasive mysid in their diets. Of nine fish species captured in August, September, and October 2007, three species had consumed <i>Hemimysis</i>: alewife (<i>Alosa pseudoharengus</i>), rock bass (<i>Ambloplites rupestris</i>), and yellow perch (<i>Perca flavescens</i>); and six species had not: round goby <i>Apollonia melanostoma</i>, smallmouth bass <i>Micropterus dolomieu</i>, spottail shiner <i>Notropis hudsonius</i>, gizzard shad <i>Dorosoma cepedianum</i>, white perch <i>Morone americana</i> and log perch <i>Percina caprodes</i>. Diets of alewives from all samples were composed predominantly of <i>Hemimysis</i> (69.6% -100% frequency of occurrence, 46.0%–74.5% dry weight diet composition). Two of 6 rock bass stomachs sampled in August contained ≥ 98.9% <i>Hemimysis</i> (10 and 40 individuals each) and one of 61 yellow perch stomachs sampled in September contained 10.0% <i>Hemimysis</i> (6 individuals) and 90.0% fish. While <i>Hemimysis</i> were observed only sparsely in the diet of most nearshore fish, their predominance in alewife diets and their omnivorous feeding behavior indicated that they have the potential to alter energy flow in Great Lakes' foodwebs.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.jglr.2009.12.002","issn":"03801330","usgsCitation":"Lantry, B., Walsh, M.G., Johnson, J.H., and McKenna, J., 2010, Occurrence of the Great Lake's most recent invader, <i>Hemimysis anomala</i>, in the diet of fishes in southeastern Lake Ontario: Journal of Great Lakes Research, v. 36, no. 1, p. 179-183, https://doi.org/10.1016/j.jglr.2009.12.002.","productDescription":"5 p.","startPage":"179","endPage":"183","costCenters":[{"id":357,"text":"Lake Ontario Biological Station","active":false,"usgs":true}],"links":[{"id":215779,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jglr.2009.12.002"},{"id":243604,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Lake Ontario","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -80.1391,43.073 ], [ -80.1391,44.2705 ], [ -75.9829,44.2705 ], [ -75.9829,43.073 ], [ -80.1391,43.073 ] ] ] } } ] }","volume":"36","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6c39e4b0c8380cd74afe","contributors":{"authors":[{"text":"Lantry, B.F.","contributorId":19105,"corporation":false,"usgs":true,"family":"Lantry","given":"B.F.","email":"","affiliations":[],"preferred":false,"id":446812,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Walsh, M.

Components of the Earths climate system that vary over long timescales, such as ice sheets and vegetation, could have an important effect on this temperature sensitivity, but have often been neglected. Here we use a coupled atmosphere-ocean general circulation model to simulate the climate of the mid-Pliocene warm period (about three million years ago), and analyse the forcings and feedbacks that contributed to the relatively warm temperatures. Furthermore, we compare our simulation with proxy records of mid-Pliocene sea surface temperature. Taking these lines of evidence together, we estimate that the response of the Earth system to elevated atmospheric carbon dioxide concentrations is 30-50% greater than the response based on those fast-adjusting components of the climate system that are used traditionally to estimate climate sensitivity. We conclude that targets for the long-term stabilization of atmospheric greenhouse-gas concentrations aimed at preventing a dangerous human interference with the climate system should take into account this higher sensitivity of the Earth system. ?? 2010 Macmillan Publishers Limited.

These investigations demonstrated that subseafloor microbes are unevenly distributed and that cell abundances and metabolic activities are often independent from sediment depths, with increased prokaryotic activity at geochemical and/or sedimentary interfaces. In this study we demonstrate that microbial populations vary at the scale of individual beds in the biogenic oozes of a drill site in the eastern equatorial Pacific (Ocean Drilling Program Leg 201, Site 1226). We relate bedding-scale changes in biogenic ooze sediment composition to organic carbon (OC) and microbial cell concentrations using high-resolution color reflectance data as proxy for lithology. Our analyses demonstrate that microbial concentrations are an order of magnitude higher in the more organic-rich diatom oozes than in the nannofossil oozes. The variations mimic small-scale variations in diatom abundance and OC, indicating that the modern distribution of microbial biomass is ultimately controlled by Milankovitch-frequency variations in past oceanographic conditions. ?? 2010 Geological Society of America.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1130/G30207.1","issn":"00917613","usgsCitation":"Aiello, I., and Bekins, B., 2010, Milankovitch-scale correlations between deeply buried microbial populations and biogenic ooze lithology: Geology, v. 38, no. 1, p. 79-82, https://doi.org/10.1130/G30207.1.","startPage":"79","endPage":"82","numberOfPages":"4","costCenters":[],"links":[{"id":216866,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/G30207.1"},{"id":244764,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"38","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a572ce4b0c8380cd6dadd","contributors":{"authors":[{"text":"Aiello, I.W.","contributorId":39993,"corporation":false,"usgs":true,"family":"Aiello","given":"I.W.","email":"","affiliations":[],"preferred":false,"id":443762,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bekins, B.A.","contributorId":98309,"corporation":false,"usgs":true,"family":"Bekins","given":"B.A.","email":"","affiliations":[],"preferred":false,"id":443763,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Therefore, understanding their spatial use in this environment is a priority for conservation efforts. We studied the fine scale daily movements and habitat use of East Pacific green turtles (<i>Chelonia mydas</i>) at Laguna San Ignacio, a shallow coastal lagoon in Baja California Sur, Mexico where sea turtles are subject to high levels of gillnet bycatch and directed hunting. Six turtles ranging from 44.6 to 83.5&nbsp;cm in straight carapace length were tracked for short deployments (1 to 6 d) with GPS-VHF telemetry. Turtles were active throughout diurnal, nocturnal, and crepuscular periods. Although they moved greater total distances during daytime, their speed of travel and net displacement remained consistent throughout 24-h periods. A positive selection for areas of seagrass and moderate water depth (5 to 10&nbsp;m) was determined using Ivlev's electivity index, with neutral selection for shallow water (&lt;&nbsp;5&nbsp;m) and avoidance of deep water (&gt;&nbsp;10&nbsp;m). Turtles exhibited two distinct behavioral movement patterns: circular movements with high fidelity to the capture&ndash;release location and meandering movements with low fidelity to the capture&ndash;release location. Our results indicate that green turtles were active throughout the diel cycle while traveling large distances and traversing multiple habitats over short temporal

It is unclear whether population declines in natural-gas fields are caused by avoidance or demographic impacts, or the age classes that are most affected. Land and wildlife management agencies need information on how energy developments affect sage-grouse populations to ensure informed land-use decisions are made, effective mitigation measures are identified, and appropriate monitoring programs are implemented (Sawyer et al. 2006). We used information from radio-equipped greater sage-grouse and lek counts to investigate natural-gas development influences on 1) the distribution of, and 2) the probability of recruiting yearling males and females into breeding populations in the Upper Green River Basin of southwestern Wyoming, USA. Yearling males avoided leks near the infrastructure of natural-gas fields when establishing breeding territories; yearling females avoided nesting within 950 m of the infrastructure of natural-gas fields. Additionally, both yearling males and yearling females reared in areas where infrastructure was present had lower annual survival, and yearling males established breeding territories less often, compared to yearlings reared in areas with no infrastructure. Our results supply mechanisms for population-level declines of sage-grouse documented in natural-gas fields, and suggest to land managers that current stipulations on development may not provide management solutions. Managing landscapes so that suitably sized and located regions remain undeveloped may be an effective strategy to sustain greater sage-grouse populations affected by energy developments. ?? 2010 The Wildlife Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.2193/2008-291","issn":"0022541X","usgsCitation":"Holloran, M., Kaiser, R., and Hubert, W., 2010, Yearling greater sage-grouse response to energy development in Wyoming: Journal of Wildlife Management, v. 74, no. 1, p. 65-72, https://doi.org/10.2193/2008-291.","startPage":"65","endPage":"72","numberOfPages":"8","costCenters":[],"links":[{"id":216930,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2193/2008-291"},{"id":244832,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"74","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-12-13","publicationStatus":"PW","scienceBaseUri":"505bd205e4b08c986b32f630","contributors":{"authors":[{"text":"Holloran, M.J.","contributorId":50000,"corporation":false,"usgs":true,"family":"Holloran","given":"M.J.","email":"","affiliations":[],"preferred":false,"id":443776,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kaiser, R.C.","contributorId":78584,"corporation":false,"usgs":true,"family":"Kaiser","given":"R.C.","email":"","affiliations":[],"preferred":false,"id":443777,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hubert, W.A.","contributorId":12822,"corporation":false,"usgs":true,"family":"Hubert","given":"W.A.","email":"","affiliations":[],"preferred":false,"id":443775,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Nutrient concentration and flux in the Mississippi River have increased substantially over the last century because of changes in land use, climate, hydrology, and river management and engineering. As in other large floodplain rivers, rates of processes that cycle nitrogen and phosphorus in the UMR exhibit pronounced spatial and temporal heterogeneity because of the complex morphology of the river. This spatial variability in nutrient processing creates clear spatial patterns in nutrient concentrations. For example, nitrate concentrations generally are much lower in off-channel areas than in the main channel. The specifics of in-river nutrient cycling and the effects of high rates of nutrient input on UMR have been less studied than the factors affecting nutrient input to the river and transport to the Gulf of Mexico, and important questions concerning nutrient cycling in the UMR remain. Eutrophication and resulting changes in river productivity have only recently been investigated the UMR. These recent studies indicate that the high nutrient concentrations in the river may affect community composition of aquatic vegetation (e. g., the abundance of filamentous algae and duckweeds), dissolved oxygen concentrations in off-channel areas, and the abundance of cyanobacteria. Actions to reduce nutrient input to the river include changes in land-use practices, wetland restoration, and hydrological modifications to the river. Evidence suggests that most of the above methods can contribute to reducing nutrient concentration in, and transport by, the UMR, but the impacts of mitigation efforts will likely be only slowly realized. ??

Quaternary alluvial deposits in the modern stream channel of the Agua Fria River west of Phoenix are mined and processed to provide some of this aggregate to the greater Phoenix area. The Agua Fria drainage basin (Fig. 1) is characterized by rugged mountains with high elevations and steep stream gradients in the north, and by broad alluvial filled basins separated by elongated faultblock mountain ranges in the south. The Agua Fria River, the basin’s main drainage, flows south from Prescott, AZ and west of Phoenix to the Gila River. The Waddel Dam impounds Lake Pleasant and greatly limits the flow of the Agua Fria River south of the lake. The southern portion of the watershed, south of Lake Pleasant, opens out into a broad valley where the river flows through urban and agricultural lands to its confluence with the Gila River, a tributary of the Colorado River.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Mining Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Society for Mining, Metallurgy and Exploration","issn":"00265187","usgsCitation":"Langer, W.H., Dewitt, E., Adams, D., and O’Briens, T., 2010, Geologie study off gravels of the Agua Fria River, Phoenix, AZ: Mining Engineering, v. 62, no. 2, p. 27-31.","startPage":"27","endPage":"31","numberOfPages":"5","costCenters":[],"links":[{"id":241907,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":267311,"type":{"id":15,"text":"Index Page"},"url":"https://me.smenet.org/abstract.cfm?preview=1&articleID=490&page=27"}],"volume":"62","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a2287e4b0c8380cd57118","contributors":{"authors":[{"text":"Langer, W.

In this study, we derive the shape factor of a log-geometric distribution from the ratio of frequencies between adjacent bins. The shape factor has a log straight-line relationship with the ratio of frequencies. Additionally, the calculation equations of a ratio of the mean size to the lower size-class boundary are deduced. For a specific log-geometric distribution, we find that the ratio of the mean size to the lower size-class boundary is the same. We apply our analysis to simulations based on oil and gas pool distributions from four petroleum systems of Alberta, Canada and four generated distributions. Each petroleum system in Alberta has a different shape factor. Generally, the shape factors in the four petroleum systems stabilize with the increase of discovered pool numbers. For a log-geometric distribution, the shape factor becomes stable when discovered pool numbers exceed 50 and the shape factor is influenced by the exploration efficiency when the exploration efficiency is less than 1. The simulation results show that calculated shape factors increase with those of the parent distributions, and undiscovered oil and gas resources estimated through the log-geometric distribution extrapolation are smaller than the actual values. ?? 2010 International Association for Mathematical Geology.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Natural Resources Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s11053-010-9109-x","issn":"15207439","usgsCitation":"Chenglin, L., and Charpentier, R., 2010, Quality of the log-geometric distribution extrapolation for smaller undiscovered oil and gas pool size: Natural Resources Research, v. 19, no. 1, p. 11-21, https://doi.org/10.1007/s11053-010-9109-x.","startPage":"11","endPage":"21","numberOfPages":"11","costCenters":[],"links":[{"id":216929,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s11053-010-9109-x"},{"id":244831,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"19","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-01-27","publicationStatus":"PW","scienceBaseUri":"505a9143e4b0c8380cd8019f","contributors":{"authors":[{"text":"Chenglin, L.","contributorId":90959,"corporation":false,"usgs":true,"family":"Chenglin","given":"L.","email":"","affiliations":[],"preferred":false,"id":443774,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Charpentier, Ronald R.","contributorId":33674,"corporation":false,"usgs":true,"family":"Charpentier","given":"Ronald R.","affiliations":[],"preferred":false,"id":443773,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

To investigate patterns of parasitism, we trapped rats and quantified nematodes on 13 islets of various sizes and habitat types. Most rats were parasitized (59) with an average of 12 worms per infected rat. Islet size did not greatly influence parasite population biology. Nematodes also did not appear to affect rat condition (weight to skull length). The only strong and consistent factor associated with the mean abundance of nematodes in rats was habitat (dominant cover and locally dominant plant species). Thus, nematodes were much more abundant in rats from sites dominated by coconut trees (Cocos nucifera). Coconut trees may also be an introduced species at Palmyra Atoll. ??
