Their numbers and biomass can exceed those of all other amphibians, and of salmonid fishes. By contrast, metamorphosed Dicamptodon are only found infrequently, usually during formal surveys using pitfall traps, cover boards, or time constrained surveys However, we found two aggregations (23 and 27 individuals) of metamorphosed Dicamptodon ensatus during a culvert removal project at Point Reyes National Seashore, California. Furthermore, we found an additional 23 terrestrial D. ensatus in terrestrial habitat adjacent to the culverts. We did not expect these aggregations because metamorphosed individuals are so rarely encountered, and aggregations are likely to increase competition and predation in a species known to feed regularly on vertebrate prey. Deteriorating culverts might provide an unusually high-quality habitat that leads to aggregations such as we describe. Our observations may provide insight into the natural haunts of D. ensatus—underground burrows or caverns—and if so, then aggregations may be normal, but rarely seen. </p>","language":"English","publisher":"Herpetological Conservation and Biology","usgsCitation":"Fellers, G.M., Wood, L.L., Carlisle, S., and Pratt, D., 2010, Unusual subterranean aggregations of the California Giant Salamander, <i>Dicamptodon ensatus</i>: Herpetological Conservation and Biology, v. 5, no. 1, p. 149-154.","productDescription":"6 p.","startPage":"149","endPage":"154","ipdsId":"IP-082094","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":332989,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":332969,"type":{"id":15,"text":"Index Page"},"url":"https://www.herpconbio.org/contents_vol5_issue1.html"}],"volume":"5","issue":"1","publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5874b0aee4b0a829a320bb6d","contributors":{"authors":[{"text":"Fellers, Gary M. 0000-0003-4092-0285 gary_fellers@usgs.gov","orcid":"https://orcid.org/0000-0003-4092-0285","contributorId":3150,"corporation":false,"usgs":true,"family":"Fellers","given":"Gary","email":"gary_fellers@usgs.gov","middleInitial":"M.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":657974,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wood, Leslie L.","contributorId":178117,"corporation":false,"usgs":false,"family":"Wood","given":"Leslie","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":657975,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Carlisle, Sarah","contributorId":178118,"corporation":false,"usgs":false,"family":"Carlisle","given":"Sarah","email":"","affiliations":[],"preferred":false,"id":657976,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pratt, David","contributorId":174869,"corporation":false,"usgs":false,"family":"Pratt","given":"David","affiliations":[],"preferred":false,"id":657977,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

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}]}}

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.

Since that year morbidity and mortality have also been observed in the Shenandoah and Monocacy rivers. Despite much research, no single pathogen, parasite, or chemical cause for the lesions and mortality has been identified. Numerous parasites, most commonly trematode metacercariae and myxozoans; the bacterial pathogens <i>Aeromonas hydrophila</i>, <i>Aeromonas salmonicida</i>, and <i>Flavobacterium columnare</i>; and largemouth bass virus have all been observed. None have been consistently isolated or observed at all sites, however, nor has any consistent microscopic pathology of the lesions been observed. A variety of histological changes associated with exposure to environmental contaminants or stressors, including intersex (testicular oocytes), high numbers of macrophage aggregates, oxidative damage, gill lesions, and epidermal papillomas, were observed. The findings indicate that selected sensitive species may be stressed by multiple factors and constantly close to the threshold between a sustainable (healthy) and nonsustainable (unhealthy) condition. Fish health is often used as an indicator of aquatic ecosystem health, and these findings raise concerns about environmental degradation within the Potomac River drainage. Unfortunately, while much information has been gained from the studies conducted to date, due to the multiple state jurisdictions involved, competing interests, and other issues, there has been no coordinated approach to identifying and mitigating the stressors.

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 biased.&nbsp;</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wetlands","largerWorkSubtype":{"id":10,"text":"Journal

One of the three colonies, Pig's Eye, was located near a presumed source of PFCs. Based on a multivariate analysis, the pattern of nine PFC concentrations differed significantly between Pig's Eye and the upriver (P = 0.002) and downriver (P = 0.02) colonies; but not between the upriver and downriver colonies (P = 0.25). Mean concentrations of perfluorooctane sulfonate (PFOS), a major PFC compound, were significantly higher at the Pig's Eye colony (geometric mean = 940 ng/g wet weight) than at upriver (60 ng/g wet weight) and downriver (131 ng/g wet weight) colonies. Perfluorooctane sulfonate concentrations from the Pig's Eye colony are among the highest reported in bird eggs. Concentrations of PFOS in Great Blue Heron eggs from Pig's Eye were well below the toxicity thresholds estimated for Bobwhite Quail (Colinus virginianus) and Mallards (Anas platyrhynchos), but within the toxicity threshold estimated for White Leghorn Chickens (Gallus domesticus). The pattern of six PBDE congener concentrations did not differ among the three colonies (P = 0.08). Total PBDE concentrations, however, were significantly greater (P = 0.03) at Pig's Eye (geometric mean = 142 ng/g wet weight) than the upriver colony (13 ng/g wet weight). Polybrominated diphenyl ether concentrations in two of six Great Blue Heron eggs from the Pig's Eye colony were within levels associated with altered reproductive behavior in American Kestrels (Falco sparverius).","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Waterbirds","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1675/063.033.0110","issn":"15244695","usgsCitation":"Custer, T.W., Kannan, K., Tao, L., Yun, H., and Trowbridge, A., 2010, Perfluorinated compounds and polybrominated diphenyl ethers in great blue heron eggs from three colonies on the Mississippi River, Minnesota: Waterbirds, v. 33, no. 1, p. 86-95, https://doi.org/10.1675/063.033.0110.","productDescription":"10 p.","startPage":"86","endPage":"95","numberOfPages":"10","costCenters":[{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":217077,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1675/063.033.0110"},{"id":244990,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Minnesota","volume":"33","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a767de4b0c8380cd78136","contributors":{"authors":[{"text":"Custer, Thomas W. 0000-0003-3170-6519 tcuster@usgs.gov","orcid":"https://orcid.org/0000-0003-3170-6519","contributorId":2835,"corporation":false,"usgs":true,"family":"Custer","given":"Thomas","email":"tcuster@usgs.gov","middleInitial":"W.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":459459,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kannan, Kurunthachalam","contributorId":42861,"corporation":false,"usgs":true,"family":"Kannan","given":"Kurunthachalam","email":"","affiliations":[],"preferred":false,"id":459458,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Tao, Lin","contributorId":209935,"corporation":false,"usgs":false,"family":"Tao","given":"Lin","email":"","affiliations":[],"preferred":false,"id":459457,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Yun, Hun","contributorId":209936,"corporation":false,"usgs":false,"family":"Yun","given":"Hun","email":"","affiliations":[],"preferred":false,"id":459455,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Trowbridge, Annette","contributorId":44818,"corporation":false,"usgs":true,"family":"Trowbridge","given":"Annette","email":"","affiliations":[],"preferred":false,"id":459456,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

These results are the first for the Caribbean and were derived with likelihood-based approaches from 4640 nests and 44 chicks fitted with transmitters monitored in 52 colonies at St. Croix, U.S. Virgin Islands, 2003&ndash;2006.

Daily nest survival of managed colonies (fenced) was significantly higher (0.97 &plusmn; 0.02; period survival = 0.51). Variation in nest survival was best explained by a negative linear trend in daily survival, influenced by year, rain, large colony size, and nesting habitat. Daily nest-survival rates at sandy beaches (0.94 &plusmn; 0.02), offshore cays (0.93 &plusmn; 0.005), and saltflats (0.91 &plusmn; 0.02) did not differ significantly. The period survival of chicks was 0.30 &plusmn; 0.11. Estimated fledglings per nest attempt were 0.06. Demographic assessments suggested that higher reproductive rates are required for maintenance (&lambda; &ge; 1). Managed colonies could meet nest-survival thresholds, but complementary measures are needed to increase chick survival. Our findings suggest that management should target sites harboring large colonies because they had higher nest success and higher probability of use in subsequent seasons. The colonies' site dynamics suggested that immigration from other populations is plausible. This possibility relaxes breeding-productivity thresholds and advocates for coordinated conservation among populations on neighboring islands. Estimates of age-specific survival and connectivity are needed for the status of the species to be assessed appropriately and conservation priorities set.</span></p>","language":"English","publisher":"Cooper Ornithological Society","doi":"10.1525/cond.2010.090042","issn":"00105422","usgsCitation":"Lombard, C.D., Collazo, J., and McNair, D.B., 2010, Nest and chick survival and colony-site dynamics of least terns in the U.S. Virgin Islands: The Condor, v. 112, no. 1, p. 56-64, https://doi.org/10.1525/cond.2010.090042.","productDescription":"9 p.","startPage":"56","endPage":"64","numberOfPages":"9","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-011849","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":488100,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1525/cond.2010.090042","text":"Publisher Index Page"},{"id":216537,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1525/cond.2010.090042"},{"id":244414,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"U.S. Virgin Islands","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -64.90036010742186,\n              17.66953965015781\n            ],\n            [\n              -64.76028442382811,\n              17.679353156672477\n            ],\n            [\n              -64.55909729003906,\n              17.749994573141873\n            ],\n            [\n              -64.610595703125,\n              17.790535393588975\n            ],\n            [\n              -64.78019714355469,\n              17.789227768730534\n            ],\n            [\n              -64.88388061523438,\n              17.7722277744277\n            ],\n            [\n              -64.90036010742186,\n              17.74541680638779\n            ],\n            [\n              -64.90928649902344,\n              17.678698939569045\n            ],\n            [\n              -64.90036010742186,\n              17.66953965015781\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"112","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a6476e4b0c8380cd729c7","contributors":{"authors":[{"text":"Lombard, Claudia D.","contributorId":106762,"corporation":false,"usgs":true,"family":"Lombard","given":"Claudia","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":443639,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Collazo, Jaime jaime_collazo@usgs.gov","contributorId":2613,"corporation":false,"usgs":true,"family":"Collazo","given":"Jaime","email":"jaime_collazo@usgs.gov","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":false,"id":443638,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McNair, Douglas B.","contributorId":25420,"corporation":false,"usgs":false,"family":"McNair","given":"Douglas","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":443637,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

However, relatively few studies have focused on the flow thresholds at which sediment is mobilized or total sediment yields across various time scales. We examined each of these topics for a mainly urban spring (Blue Hole) and a rural spring (SP-2) in the Inner Bluegrass region of central Kentucky (USA). Suspended sediment consisted mostly of quartz silt and sand, with lesser amounts of calcite and organic matter. Total suspended sediment (TSS) values measured during storm flow were greater at SP-2 than at Blue Hole. By aggregating data from four storms during 2 years, we found that median suspended-sediment size jumped as Q exceeded ???0.5 m<sup>3</sup>/s for both springs. At Blue Hole, TSS tended to vary with Q and capacity approached 1 g/L, but no systematic relationship between TSS and Q was evident at SP-2. Sediment fluxes from the Blue Hole basin were ???2 orders of magnitude greater for storms in March (2002 and 2004) than September (2002 and 2003). In contrast, sediment fluxes from the SP-2 basin were of similar magnitude in September 2003 and March 2004. The overall range of area-normalized fluxes for both springs, 9.16 ?? 10<sup>-3</sup>-4.45 ?? 10<sup>2</sup> kg/(ha h), overlaps values reported for farm plots and a stream in the Inner Bluegrass region and for other spring basins in the eastern USA and western Europe. Sediment compositions, sizes, and responses to storms in the basins may differ because of land use (e.g., the extent of impervious cover in the Blue Hole basin), basin size (larger for Blue Hole), conduit architecture, which appears to be more complex in the Blue Hole basin, and the impoundment of SP-2, which may have promoted decadal-scale storage of sediment upgradient. ?? 2009 Elsevier B.V.

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}]}}

Rates of whole-system metabolism (production and respiration) are fundamental indicators of ecosystem structure and function. Although first-order, proximal controls are well understood, assessments of the interactions between proximal controls and distal controls, such as land use and geographic region, are lacking. Thus, the influence of land use on stream metabolism across geographic regions is unknown. Further, there is limited understanding of how land use may alter variability in ecosystem metabolism across regions.2. Stream metabolism was measured in nine streams in each of eight regions (n = 72) across the United States and Puerto Rico. In each region, three streams were selected from a range of three land uses: agriculturally influenced, urban-influenced, and reference streams. Stream metabolism was estimated from diel changes in dissolved oxygen concentrations in each stream reach with correction for reaeration and groundwater input.3. Gross primary production (GPP) was highest in regions with little riparian vegetation (sagebrush steppe in Wyoming, desert shrub in Arizona/New Mexico) and lowest in forested regions (North Carolina, Oregon). In contrast, ecosystem respiration (ER) varied both within and among regions. Reference streams had significantly lower rates of GPP than urban or agriculturally influenced streams.4. GPP was positively correlated with photosynthetically active radiation and autotrophic biomass. Multiple regression models compared using Akaike's information criterion (AIC) indicated GPP increased with water column ammonium and the fraction of the catchment in urban and reference land-use categories. Multiple regression models also identified velocity, temperature, nitrate, ammonium, dissolved organic carbon, GPP, coarse benthic organic matter, fine benthic organic matter and the fraction of all land-use categories in the catchment as regulators of ER.5. Structural equation modelling indicated significant distal as well as proximal control pathways including a direct effect of land-use on GPP as well as SRP, DIN, and PAR effects on GPP; GPP effects on autotrophic biomass, organic matter, and ER; and organic matter effects on ER.6. Overall, consideration of the data separated by land-use categories showed reduced inter-regional variability in rates of metabolism, indicating that the influence of agricultural and urban land use can obscure regional differences in stream metabolism. ?? 2010 Blackwell Publishing Ltd.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Freshwater Biology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1365-2427.2010.02422.x","issn":"00465070","usgsCitation":"Bernot, M.J., Sobota, D.J., Hall, R., Mulholland, P.J., Dodds, W.K., Webster, J., Tank, J.L., Ashkenas, L., Cooper, L.W., Dahm, C., Gregory, S., Grimm, N.B., Hamilton, S.K., Johnson, S.L., McDowell, W.H., Meyer, J., Peterson, B., Poole, G.C., Maurice, V.H., Arango, C., Beaulieu, J.J., Burgin, A.J., Crenshaw, C., Helton, A.M., Johnson, L., Merriam, J., Niederlehner, B., O’Brien, J.M., Potter, J.D., Sheibley, R., Thomas, S.M., and Wilson, K., 2010, Inter-regional comparison of land-use effects on stream metabolism: Freshwater Biology, v. 55, no. 9, p. 1874-1890, https://doi.org/10.1111/j.1365-2427.2010.02422.x.","startPage":"1874","endPage":"1890","numberOfPages":"17","costCenters":[],"links":[{"id":246042,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218062,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1365-2427.2010.02422.x"}],"volume":"55","issue":"9","noUsgsAuthors":false,"publicationDate":"2010-08-15","publicationStatus":"PW","scienceBaseUri":"505a3ca3e4b0c8380cd62ee6","contributors":{"authors":[{"text":"Bernot, M.

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.

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}]}}

We used telemetry locations collected from 140 adult female elk during 20002003 and 20072008 to identify factors influencing the migration of northern Yellowstone elk. Elk wintered in 2 semidistinct herd segments and migrated 10140 km to at least 12 summer areas in Yellowstone National Park (YNP) and nearby areas of Montana. Spring migrations were delayed after winters with increased snow pack, with earlier migration in years with earlier vegetation green-up. Elk wintering at lower elevations outside YNP migrated an average of 13 days earlier than elk at higher elevations. The timing of autumn migrations varied annually, but elk left their summer ranges at about the same time regardless of elevation, wolf numbers, or distance to their wintering areas. Elk monitored for multiple years typically returned to the same summer (96 fidelity, n 52) and winter (61 fidelity, n 41) ranges. Elk that wintered at lower elevations in or near the northwestern portion of the park tended to summer in the western part of YNP (56), and elk that wintered at higher elevations spent summer primarily in the eastern and northern parts of the park (82). Elk did not grossly modify their migration timing, routes, or use areas after wolf restoration. Elk mortality was low during summer and migration (8 of 225 elk-summers). However, spatial segregation and differential mortality and recruitment between herd segments on the northern winter range apparently contributed to a higher proportion of the elk population wintering outside the northwestern portion of YNP and summering in the western portion of the park. This change could shift wolf spatial dynamics more outside YNP and increase the risk of transmission of brucellosis from elk to cattle north of the park. ?? 2010 American Society of Mammalogists.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Mammalogy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1644/08-MAMM-A-252.1","issn":"00222372","usgsCitation":"White, P., Proffitt, K., Mech, L., Evans, S., Cunningham, J., and Hamlin, K., 2010, Migration of northern yellowstone elk: Implications of spatial structuring: Journal of Mammalogy, v. 91, no. 4, p. 827-837, https://doi.org/10.1644/08-MAMM-A-252.1.","startPage":"827","endPage":"837","numberOfPages":"11","costCenters":[],"links":[{"id":475985,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1644/08-mamm-a-252.1","text":"Publisher Index Page"},{"id":217157,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1644/08-MAMM-A-252.1"},{"id":245078,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"91","issue":"4","noUsgsAuthors":false,"publicationDate":"2010-08-16","publicationStatus":"PW","scienceBaseUri":"505a5709e4b0c8380cd6d9eb","contributors":{"authors":[{"text":"White, P.J.","contributorId":91436,"corporation":false,"usgs":true,"family":"White","given":"P.J.","affiliations":[],"preferred":false,"id":459037,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Proffitt, K.M.","contributorId":34235,"corporation":false,"usgs":true,"family":"Proffitt","given":"K.M.","email":"","affiliations":[],"preferred":false,"id":459034,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mech, L.D. 0000-0003-3944-7769","orcid":"https://orcid.org/0000-0003-3944-7769","contributorId":75466,"corporation":false,"usgs":false,"family":"Mech","given":"L.D.","email":"","affiliations":[],"preferred":false,"id":459036,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Evans, S.B.","contributorId":19359,"corporation":false,"usgs":true,"family":"Evans","given":"S.B.","email":"","affiliations":[],"preferred":false,"id":459033,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Cunningham, J.A.","contributorId":101872,"corporation":false,"usgs":true,"family":"Cunningham","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":459038,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Hamlin, K.L.","contributorId":37174,"corporation":false,"usgs":true,"family":"Hamlin","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":459035,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

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.

[2005]. Astron. J. 129, 2887-2901) to characterize the before and after full Moon radiance variation for a typical highlands site and a typical mare site. Focusing on the phase angle range 45??. <. ??<. 50??, we test two different physical models, macroscopic roughness and multiple scattering between regolith particles, for their ability to quantitatively reproduce the measured radiance difference. Our method for estimating the rms slope angle is unique and model-independent in the sense that the measured radiance factor I/. F at small incidence angles (high Sun) is used as an estimate of I/. F for zero roughness regolith. The roughness is determined from the change in I/. F at larger incidence angles. We determine the roughness for 23 wavelengths from 350 to 939. nm. There is no significant wavelength dependence. The average rms slope angle is 22.2?? ?? 1.3?? for the mare site and 34.1?? ?? 2.6?? for the highland site. These large slopes, which are similar to previous \"photometric roughness\" estimates, require that sub-mm scale \"micro-topography\" dominates roughness measurements based on photometry, consistent with the conclusions of Helfenstein and Shepard (Helfenstein, P., Shepard, M.K. [1999]. Icarus 141, 107-131). We then tested an alternative and very different model for the before and after full Moon I/. F variation: multiple scattering within a flat layer of realistic regolith particles. This model consists of a log normal size distribution of spheres that match the measured distribution of particles in a typical mature lunar soil 72141,1 (McKay, D.S., Fruland, R.M., Heiken, G.H. [1974]. Proc. Lunar Sci. Conf. 5, Geochim. Cosmochim. Acta 1 (5), 887-906). The model particles have a complex index of refraction 1.65-0.003. i, where 1.65 is typical of impact-generated lunar glasses. Of the four model parameters, three were fixed at values determined from Apollo lunar soils: the mean radius and width of the log normal size distribution and the real part of the refraction index. We used FORTRAN programs from Mishchenko et al. (Mishchenko, M.I., Dlugach, J.M., Yanovitskij, E.G., Zakharova, N.T. [1999]. J. Quant. Spectrosc. Radiat. Trans. 63, 409-432; Mishchenko, M.I., Travis, L.D., Lacis, A.A. [2002]. Scattering, Absorption and Emission of Light by Small Particles. Cambridge Univ. Press, New York. <. http://www.giss.nasa.gov/staff/mmishchenko/books.html>) to calculate the scattering matrix and solve the radiative transfer equation for I/. F. The mean single scattering albedo is ??=0.808, the asymmetry parameter is ???cos. ?????=0.77 and the phase function is very strongly peaked in both the forward and backward scattering directions. The fit to the observations for the highland site is excellent and multiply scattered photons contribute 80% of I/. F. We conclude that either model, roughness or multiple scattering, can match the observations, but that the strongly anisotropic phase functions of realistic particles require rigorous calculation of many orders of scattering or spurious photometric roughness estimates are guaranteed. Our multiple scattering calculation is the first to combine: (1) a regolith model matched to the measured particle size distribution and index of refraction of the lunar soil, (2) a rigorous calculation of the particle phase function and solution of the radiative transfer equation, and (3) application to lunar photometry with absolute radiance calibration. ?? 2010 Elsevier Inc.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Icarus","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1016/j.icarus.2010.03.025","issn":"00191035","usgsCitation":"Goguen, J., Stone, T., Kieffer, H.H., and Buratti, B.J., 2010, A new look at photometry of the Moon: Icarus, v. 208, no. 2, p. 548-557, https://doi.org/10.1016/j.icarus.2010.03.025.","startPage":"548","endPage":"557","numberOfPages":"10","costCenters":[],"links":[{"id":217425,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.icarus.2010.03.025"},{"id":245371,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"208","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e4a5e4b0c8380cd467d2","contributors":{"authors":[{"text":"Goguen, J.D.","contributorId":33950,"corporation":false,"usgs":true,"family":"Goguen","given":"J.D.","email":"","affiliations":[],"preferred":false,"id":459556,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stone, T.C.","contributorId":74874,"corporation":false,"usgs":true,"family":"Stone","given":"T.C.","email":"","affiliations":[],"preferred":false,"id":459559,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kieffer, H.

However, classic capture-recapture models do not allow for misidentification of animals which is a potentially very serious problem with natural tags. Statistical analysis of misidentification processes is extremely difficult using traditional likelihood methods but is easily handled using Bayesian methods. We present a general framework for Bayesian analysis of categorical data arising from a latent multinomial distribution. Although our work is motivated by a specific model for misidentification in closed population capture-recapture analyses, with crucial assumptions which may not always be appropriate, the methods we develop extend naturally to a variety of other models with similar structure. Suppose that observed frequencies f are a known linear transformation f = A???x of a latent multinomial variable x with cell probability vector ?? = ??(??). Given that full conditional distributions [?? | x] can be sampled, implementation of Gibbs sampling requires only that we can sample from the full conditional distribution [x | f, ??], which is made possible by knowledge of the null space of A???. We illustrate the approach using two data sets with individual misidentification, one simulated, the other summarizing recapture data for salamanders based on natural marks. ?? 2009, The International Biometric Society.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Biometrics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1111/j.1541-0420.2009.01244.x","issn":"0006341X","usgsCitation":"Link, W., Yoshizaki, J., Bailey, L., and Pollock, K.H., 2010, Uncovering a latent multinomial: Analysis of mark-recapture data with misidentification: Biometrics, v. 66, no. 1, p. 178-185, https://doi.org/10.1111/j.1541-0420.2009.01244.x.","startPage":"178","endPage":"185","numberOfPages":"8","costCenters":[],"links":[{"id":475979,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1541-0420.2009.01244.x","text":"Publisher Index Page"},{"id":217074,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1541-0420.2009.01244.x"},{"id":244986,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"66","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-03-17","publicationStatus":"PW","scienceBaseUri":"505bbc31e4b08c986b328ac5","contributors":{"authors":[{"text":"Link, W.A. 0000-0002-9913-0256","orcid":"https://orcid.org/0000-0002-9913-0256","contributorId":8815,"corporation":false,"usgs":true,"family":"Link","given":"W.A.","affiliations":[],"preferred":false,"id":459153,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yoshizaki, J.","contributorId":79596,"corporation":false,"usgs":true,"family":"Yoshizaki","given":"J.","email":"","affiliations":[],"preferred":false,"id":459156,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bailey, L.L. 0000-0002-5959-2018","orcid":"https://orcid.org/0000-0002-5959-2018","contributorId":61006,"corporation":false,"usgs":true,"family":"Bailey","given":"L.L.","affiliations":[],"preferred":false,"id":459154,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pollock, K.

We visited a total of 196 randomly selected sampling stations on 12 shallow (&lt;10&nbsp;m) patch reefs and measured physical variables (e.g., substratum rugosity, substratum type) and benthic and fish community variables. We also incorporated data on substratum rugosity collected remotely via airborne laser surveying (Experimental Advanced Airborne Research Lidar—EAARL). Across all stations, only weak relationships were found between physical, benthic cover, and fish assemblage variables. Much of the variance was attributable to a “reef effect,” meaning that community structure and organism abundances were more variable at stations among reefs than within reefs.
