Surface soil samples (<i>n</i> = 315) were analyzed for carbon content, particle size distribution, and 15 agronomically important elements (Mehlich-III extraction). When partial least squares (PLS) regression of imagery-derived reflectance spectra was used to predict analyte concentrations, 13 of the 19 analytes were predicted with <i>R</i><sup>2</sup> > 0.50, including carbon (0.65), aluminum (0.76), iron (0.75), and silt content (0.79). Comparison of 15 spectral math preprocessing treatments showed that a simple first derivative worked well for nearly all analytes. The resulting PLS factors were exported as a vector of coefficients and used to calculate predicted maps of soil properties for each field. Image smoothing with a 3 &times; 3 low-pass filter prior to spectral data extraction improved prediction accuracy. The resulting raster maps showed variation associated with topographic factors, indicating the effect of soil redistribution and moisture regime on in-field spatial variability. High-resolution maps of soil analyte concentrations can be used to improve precision environmental management of farmlands.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied and Environmental Soil Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Hindawi Publishing Corporation","publisherLocation":"Cairo, Egypt","doi":"10.1155/2011/358193","usgsCitation":"Hively, W., McCarty, G.W., Reeves, J.B., Lang, M., Oesterling, R.A., and Delwiche, S.R., 2011, Use of airborne hyperspectral imagery to map soil parameters in tilled agricultural fields: Applied and Environmental Soil Science, v. 2011, no. 358193, 13 p., https://doi.org/10.1155/2011/358193.","productDescription":"13 p.","numberOfPages":"13","costCenters":[{"id":242,"text":"Eastern Geographic Science Center","active":true,"usgs":true}],"links":[{"id":474777,"rank":101,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1155/2011/358193","text":"Publisher Index Page"},{"id":204685,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":115749,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1155/2011/358193","linkFileType":{"id":5,"text":"html"}}],"volume":"2011","issue":"358193","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbeaee4b08c986b32970e","contributors":{"authors":[{"text":"Hively, W.

This study concerned the development of an optimal strategy for the restoration and management of scrub habitat at Merritt Island National Wildlife Refuge, which contains one of the few remaining large populations of scrub-jays in Florida. There are documented differences in the reproductive and survival rates of scrubjays among discrete classes of scrub height (<120 cm or \"short\"; 120-170 cm or \"optimal\"; .170 cm or \"tall\"; and a combination of tall and optimal or \"mixed\"), and our objective was to calculate a state-dependent management strategy that would maximize the long-term growth rate of the resident scrub-jay population. We used aerial imagery with multistate Markov models to estimate annual transition probabilities among the four scrub-height classes under three possible management actions: scrub restoration (mechanical cutting followed by burning), a prescribed burn, or no intervention. A strategy prescribing the optimal management action for management units exhibiting different proportions of scrub-height classes was derived using dynamic programming. Scrub restoration was the optimal management action only in units dominated by mixed and tall scrub, and burning tended to be the optimal action for intermediate levels of short scrub. The optimal action was to do nothing when the amount of short scrub was greater than 30%, because short scrub mostly transitions to optimal height scrub (i.e., that state with the highest demographic success of scrub-jays) in the absence of intervention. Monte Carlo simulation of the optimal policy suggested that some form of management would be required every year. We note, however, that estimates of scrub-height transition probabilities were subject to several sources of uncertainty, and so we explored the management implications of alternative sets of transition probabilities. Generally, our analysis demonstrated the difficulty of managing for a species that requires midsuccessional habitat, and suggests that innovative management tools may be needed to help ensure the persistence of scrub-jays at Merritt Island National Wildlife Refuge. The development of a tailored monitoring program as a component of adaptive management could help reduce uncertainty about controlled and uncontrolled variation in transition probabilities of scrub-height and thus lead to improved decision making.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Fish and Wildlife Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Fish and Wildlife Service","publisherLocation":"Arlington, VA","doi":"10.3996/012011-JFWM-003","usgsCitation":"Johnson, F.A., Breininger, D.R., Duncan, B.W., Nichols, J., Runge, M.C., and Williams, B.K., 2011, A Markov decision process for managing habitat for Florida scrub-jays: Journal of Fish and Wildlife Management, v. 2, no. 2, p. 234-246, https://doi.org/10.3996/012011-JFWM-003.","productDescription":"13 p.","startPage":"234","endPage":"246","costCenters":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"links":[{"id":474779,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.3996/012011-jfwm-003","text":"Publisher Index Page"},{"id":204634,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":115665,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.3996/012011-JFWM-003","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Florida","volume":"2","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e2e9e4b0c8380cd45d15","contributors":{"authors":[{"text":"Johnson, Fred A. 0000-0002-5854-3695 fjohnson@usgs.gov","orcid":"https://orcid.org/0000-0002-5854-3695","contributorId":2773,"corporation":false,"usgs":true,"family":"Johnson","given":"Fred","email":"fjohnson@usgs.gov","middleInitial":"A.","affiliations":[{"id":455,"text":"National Wetlands Research Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true},{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true}],"preferred":true,"id":356001,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Breininger, David R.","contributorId":6990,"corporation":false,"usgs":true,"family":"Breininger","given":"David","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":356003,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Duncan, Brean W.","contributorId":32663,"corporation":false,"usgs":true,"family":"Duncan","given":"Brean","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":356004,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nichols, James D. 0000-0002-7631-2890 jnichols@usgs.gov","orcid":"https://orcid.org/0000-0002-7631-2890","contributorId":405,"corporation":false,"usgs":true,"family":"Nichols","given":"James D.","email":"jnichols@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":356000,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Runge, Michael C. 0000-0002-8081-536X mrunge@usgs.gov","orcid":"https://orcid.org/0000-0002-8081-536X","contributorId":3358,"corporation":false,"usgs":true,"family":"Runge","given":"Michael","email":"mrunge@usgs.gov","middleInitial":"C.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":356002,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Williams, B.

To assist in this endeavor, during 2003-07 the U.S. Geological Survey (USGS), in cooperation with the Onondaga Lake Partnership, developed a precipitation-runoff model of the 285-square-mile Onondaga Lake Basin with the computer program Hydrological Simulation Program-Fortran (HSPF). The model was intended to provide a tool whereby the processes responsible for the generation of loads of sediment and nutrients that are transported to Onondaga Lake could be better understood. This objective was only partly attained because data for calibration of the model were available from monitoring sites only at or near the mouths of the major tributaries to Onondaga Lake; no calibration data from headwater subbasins, where the loads originated, were available. To address this limitation and thereby decrease the uncertainty in the simulated results that were associated with headwater processes, the USGS conducted a 3-year (2005-08) basinwide study to assess the quality of surface water in the Onondaga Lake Basin. The study quantified the relative contributions of nonpoint sources associated with the major land uses and land covers in the basin and also monitored known sources and presumed sinks of sediment and nutrient loads, which previously had not been evaluated. The use of the newly acquired data to recalibrate the HSPF model resulted in improvements in the simulation of processes in the headwater subbasins, including suspended-sediment, orthophosphate, and phosphorus generation and transport.\nSimulation of streamflows in small subbasins was improved by adjusting model parameter values to match base flows, storm peaks, and storm recessions more precisely than had been done with the original model. Simulated recessional and low flows were either increased or decreased as appropriate for a given stream, and simulated peak flows generally were lowered in the revised model. The use of suspended-sediment concentrations rather than concentrations of the surrogate constituent, total suspended solids, resulted in increases in the simulated low-flow sediment concentrations and, in most cases, decreases in the simulated peak-flow sediment concentrations. Simulated orthophosphate concentrations in base flows generally increased but decreased for peak flows in selected headwater subbasins in the revised model. Compared with the original model, phosphorus concentrations simulated by the revised model were comparable in forested subbasins, generally decreased in developed and wetland-dominated subbasins, and increased in agricultural subbasins. A final revision to the model was made by the addition of the simulation of chloride (salt) concentrations in the Onondaga Creek Basin to help water-resource managers better understand the relative contributions of salt from multiple sources in this particular tributary. The calibrated revised model was used to (1) compute loading rates for the various land types that were simulated in the model, (2) conduct a watershed-management analysis that estimated the portion of the total load that was likely to be transported to Onondaga Lake from each of the modeled subbasins, (3) compute and assess chloride loads to Onondaga Lake from the Onondaga Creek Basin, and (4) simulate precolonization (forested) conditions in the basin to estimate the probable minimum phosphorus loads to the lake.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20115203","collaboration":"Prepared in cooperation with the Onondaga Lake Partnership","usgsCitation":"Coon, W.F., 2011, Improvement in precipitation-runoff model simulations by recalibration with basin-specific data, and subsequent model applications, Onondaga Lake Basin, Onondaga County, New York: U.S. Geological Survey Scientific Investigations Report 2011-5203, x, 37 p., https://doi.org/10.3133/sir20115203.","productDescription":"x, 37 p.","onlineOnly":"Y","costCenters":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"links":[{"id":116441,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2011_5203.gif"},{"id":112501,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2011/5203/","linkFileType":{"id":5,"text":"html"}}],"state":"New York","county":"Onondaga","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -76.5,42.7 ], [ -76.5,43.166666666666664 ], [ -75.96666666666667,43.166666666666664 ], [ -75.96666666666667,42.7 ], [ -76.5,42.7 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a3969e4b0c8380cd618f8","contributors":{"authors":[{"text":"Coon, William F. 0000-0002-7007-7797 wcoon@usgs.gov","orcid":"https://orcid.org/0000-0002-7007-7797","contributorId":1765,"corporation":false,"usgs":true,"family":"Coon","given":"William","email":"wcoon@usgs.gov","middleInitial":"F.","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":true,"id":355918,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

With the support and cooperation of visionaries, financiers, scientists, and other individuals and organizations, HVO has successfully achieved 100 years of continuous monitoring of Hawaiian volcanoes. As we celebrate this milestone anniversary, we express our sincere mahalo&mdash;thanks&mdash;to the people who have contributed to and participated in HVO&rsquo;s mission during this past century. First and foremost, we owe a debt of gratitude to the late Thomas A. Jaggar, Jr., the geologist whose vision and efforts led to the founding of HVO. We also acknowledge the pioneering contributions of the late Frank A. Perret, who began the continuous monitoring of K&#299;lauea in 1911, setting the stage for Jaggar, who took over the work in 1912. Initial support for HVO was provided by the Massachusetts Institute of Technology (MIT) and the Carnegie Geophysical Laboratory, which financed the initial cache of volcano monitoring instruments and Perret&rsquo;s work in 1911. The Hawaiian Volcano Research Association, a group of Honolulu businessmen organized by Lorrin A. Thurston, also provided essential funding for HVO&rsquo;s daily operations starting in mid-1912 and continuing for several decades. Since HVO&rsquo;s beginning, the University of Hawai&#699;i (UH), called the College of Hawaii until 1920, has been an advocate of HVO&rsquo;s scientific studies. We have benefited from collaborations with UH scientists at both the Hilo and M&#228;noa campuses and look forward to future cooperative efforts to better understand how Hawaiian volcanoes work. The U.S. Geological Survey (USGS) has operated HVO continuously since 1947. Before then, HVO was under the administration of various Federal agencies&mdash;the U.S. Weather Bureau, at the time part of the Department of Agriculture, from 1919 to 1924; the USGS, which first managed HVO from 1924 to 1935; and the National Park Service from 1935 to 1947. For 76 of its first 100 years, HVO has been part of the USGS, the Nation&rsquo;s premier Earth science agency. It currently operates under the direction of the USGS Volcano Science Center, which now supports five volcano observatories covering six U.S. areas&mdash;Hawai&#699;i (HVO), Alaska and the Northern Mariana Islands (Alaska Volcano Observatory), Washington and Oregon (Cascades Volcano Observatory), California (California Volcano Observatory), and the Yellowstone region (Yellowstone Volcano Observatory). Although the National Park Service (NPS) managed HVO for only 12 years, HVO has enjoyed a close working relationship with Hawai&#699;i Volcanoes National Park (named Hawaii National Park until 1961) since the park&rsquo;s founding in 1916. Today, as in past years, the USGS and NPS work together to ensure the safety and education of park visitors. We are grateful to all park employees, particularly Superintendent Cindy Orlando and Chief Ranger Talmadge Magno and their predecessors, for their continuing support of HVO&rsquo;s mission. HVO also works closely with the Hawai&#699;i County Civil Defense. During volcanic and earthquake crises, we have appreciated the support of civil defense staff, especially that of Harry Kim and Quince Mento, who administered the agency during highly stressful episodes of K&#299;lauea's ongoing eruption. Our work in remote areas on Hawai&#699;i&rsquo;s active volcanoes is possible only with the able assistance of Hawai&#699;i County and private pilots who have safely flown HVO staff to eruption sites through the decades. A special mahalo goes to David Okita, who has been HVO&rsquo;s principal helicopter pilot for more than two decades. Many commercial and Civil Air Patrol pilots have also assisted HVO by reporting their observations during various eruptive events. Hawai&#699;i&rsquo;s news media&mdash;print, television, radio, and online sources&mdash;do an excellent job of distributing volcano and earthquake information to the public. Their assistance is invaluable to HVO, especially during times of crisis. HVO&rsquo;s efforts to provide timely and accurate scientific information about Hawaiian volcanoes and earthquakes succeed only because of you, our receptive and keenly aware public. By following the activity of Hawai&#699;i&rsquo;s active volcanoes through our daily eruption updates posted on the HVO website, viewing HVO webcam images, reading our weekly &ldquo;Volcano Watch&rdquo; articles, and attending our public lectures, you help us to ensure that you can live safely with Hawai&#699;i&rsquo;s dynamic volcanoes. To everyone who has shared in HVO&rsquo;s reaching this milestone&mdash;100 years of continuous volcano monitoring&mdash;we extend our deepest gratitude. <i>Mahalo nui loa!</i>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/gip135","usgsCitation":"Babb, J., Kauahikaua, J.P., and Tilling, R.I., 2011, The story of the Hawaiian Volcano Observatory -- A remarkable first 100 years of tracking eruptions and earthquakes: U.S. Geological Survey General Information Product 135, vi, 63 p; PDF Downloads of Report in standard resolution, for printing, and for ebooks and tablets, https://doi.org/10.3133/gip135.","productDescription":"vi, 63 p; PDF Downloads of Report in standard resolution, for printing, and for ebooks and tablets","startPage":"i","endPage":"63","numberOfPages":"69","onlineOnly":"N","additionalOnlineFiles":"Y","temporalStart":"1912-01-01","temporalEnd":"2012-12-31","costCenters":[{"id":336,"text":"Hawaiian Volcano Observatory","active":false,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":116699,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/gip_135.gif"},{"id":112500,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/gip/135/","linkFileType":{"id":5,"text":"html"}}],"scale":"85342","country":"United States","state":"Hawai'i","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -161,18 ], [ -161,23 ], [ -154,23 ], [ -154,18 ], [ -161,18 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb07de4b08c986b324ebd","contributors":{"authors":[{"text":"Babb, Janet L.","contributorId":89659,"corporation":false,"usgs":true,"family":"Babb","given":"Janet L.","affiliations":[],"preferred":false,"id":355915,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kauahikaua, James P. 0000-0003-3777-503X jimk@usgs.gov","orcid":"https://orcid.org/0000-0003-3777-503X","contributorId":2146,"corporation":false,"usgs":true,"family":"Kauahikaua","given":"James","email":"jimk@usgs.gov","middleInitial":"P.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":355913,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Tilling, Robert I. 0000-0003-4263-7221 rtilling@usgs.gov","orcid":"https://orcid.org/0000-0003-4263-7221","contributorId":2567,"corporation":false,"usgs":true,"family":"Tilling","given":"Robert","email":"rtilling@usgs.gov","middleInitial":"I.","affiliations":[],"preferred":true,"id":355914,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Rapid detection and qualitative assessment of shaking events are possible because people begin sending public Twitter messages (tweets) with in tens of seconds after feeling shaking. Here we present and evaluate an earthquake detection procedure that relies solely on Twitter data. A tweet-frequency time series constructed from tweets containing the word \"earthquake\" clearly shows large peaks correlated with the origin times of widely felt events. To identify possible earthquakes, we use a short-term-average, long-term-average algorithm. When tuned to a moderate sensitivity, the detector finds 48 globally-distributed earthquakes with only two false triggers in five months of data. The number of detections is small compared to the 5,175 earthquakes in the USGS global earthquake catalog for the same five-month time period, and no accurate location or magnitude can be assigned based on tweet data alone. However, Twitter earthquake detections are not without merit. The detections are generally caused by widely felt events that are of more immediate interest than those with no human impact. The detections are also fast; about 75% occur within two minutes of the origin time. This is considerably faster than seismographic detections in poorly instrumented regions of the world. The tweets triggering the detections also provided very short first-impression narratives from people who experienced the shaking.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Annals of Geophysics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Istituto Nazionale di Geofisica e Vulcanologia","publisherLocation":"Rome, Italy","doi":"10.4401/ag-5364","usgsCitation":"Earle, P.S., Bowden, D.C., and Guy, M., 2011, Twitter earthquake detection: Earthquake monitoring in a social world: Annals of Geophysics, v. 54, no. 6, p. 708-715, https://doi.org/10.4401/ag-5364.","productDescription":"8 p.","startPage":"708","endPage":"715","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":474780,"rank":101,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.4401/ag-5364","text":"Publisher Index Page"},{"id":204580,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":115694,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.4401/ag-5364","linkFileType":{"id":5,"text":"html"}}],"volume":"54","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-01-14","publicationStatus":"PW","scienceBaseUri":"505bb947e4b08c986b327ba5","contributors":{"authors":[{"text":"Earle, Paul S. pearle@usgs.gov","contributorId":840,"corporation":false,"usgs":true,"family":"Earle","given":"Paul","email":"pearle@usgs.gov","middleInitial":"S.","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":false,"id":354370,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bowden, Daniel C.","contributorId":70918,"corporation":false,"usgs":true,"family":"Bowden","given":"Daniel","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":354372,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Guy, Michelle R. mguy@usgs.gov","contributorId":4235,"corporation":false,"usgs":true,"family":"Guy","given":"Michelle R.","email":"mguy@usgs.gov","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":false,"id":354371,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We focused on the South River, where the highest skin tumor prevalence (53%) in the Bay watershed had been reported. The objectives were to 1) compare tumor prevalence with nearby rivers (Severn and Rhode) and a more remote river (Choptank); 2) investigate associations between tumor prevalence and polynuclear aromatic hydrocarbons (PAHs) and alkylating agents; and 3) statistically analyze Chesapeake Bay bullhead tumor data from 1992 through 2008. All four South River collections exhibited high skin tumor prevalence (19% to 58%), whereas skin tumor prevalence was 2%, 10%, and 52% in the three Severn collections; 0% and 2% in the Choptank collections; and 5.6% in the Rhode collection.

In a subset of samples, PAH-like biliary metabolites and&nbsp;</span><sup>32</sup><span>P-DNA adducts were used as biomarkers of exposure and response to polycyclic aromatic compounds (PACs). Adducts from alkylating agents were detected as O6-methyl-2′-deoxyguanosine (O6Me-dG) and O6-ethyl-2′-deoxyguanosine (O6Et-dG) modified DNA. Bullheads from the contaminated Anacostia River were used as a positive control for DNA adducts.&nbsp;</span><sup>32</sup><span>P-DNA adduct concentrations were significantly higher in Anacostia bullhead livers compared with the other rivers. We identified alkyl DNA adducts in bullhead livers from the South and Anacostia, but not the Choptank. Neither the PAH-like bile metabolite data, sediment PAH data, nor the DNA adduct data suggest an association between liver or skin tumor prevalence and exposure to PACs or alkylating agents in the South, Choptank, Severn, or Rhode rivers. Logistic regression analysis of the Chesapeake Bay database revealed that sex and length were significant covariates for liver tumors and length was a significant covariate for skin tumors.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.scitotenv.2011.09.035","usgsCitation":"Pinkney, A.E., Harshbarger, J., Karouna-Renier, N., Jenko, K., Balk, L., Skarphedinsdottir, H., Liewenborg, B., and Rutter, M.A., 2011, Tumor prevalence and biomarkers of genotoxicity in brown bullhead (Ameiurus nebulosus) in Chesapeake Bay tributaries: Science of the Total Environment, v. 410-411, p. 248-257, https://doi.org/10.1016/j.scitotenv.2011.09.035.","productDescription":"10 p.","startPage":"248","endPage":"257","temporalStart":"1992-01-01","temporalEnd":"2008-12-31","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true},{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":204578,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","otherGeospatial":"Chesapeake Bay watershed, South River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -79.2333984375,\n              36.914764288955936\n            ],\n            [\n              -75.1025390625,\n              36.914764288955936\n            ],\n            [\n              -75.1025390625,\n              39.926588421909436\n            ],\n            [\n              -79.2333984375,\n              39.926588421909436\n            ],\n            [\n              -79.2333984375,\n              36.914764288955936\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"410-411","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb8bfe4b08c986b327a46","contributors":{"authors":[{"text":"Pinkney, Alfred E.","contributorId":14253,"corporation":false,"usgs":false,"family":"Pinkney","given":"Alfred","email":"","middleInitial":"E.","affiliations":[{"id":12750,"text":"U.S. Fish and Wildlife Service, Annapolis, MD","active":true,"usgs":false}],"preferred":false,"id":353687,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Harshbarger, John C.","contributorId":85928,"corporation":false,"usgs":true,"family":"Harshbarger","given":"John C.","affiliations":[],"preferred":false,"id":353691,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Karouna-Renier, Natalie K. 0000-0001-7127-033X","orcid":"https://orcid.org/0000-0001-7127-033X","contributorId":17357,"corporation":false,"usgs":true,"family":"Karouna-Renier","given":"Natalie K.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":353688,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Jenko, Kathryn","contributorId":6720,"corporation":false,"usgs":true,"family":"Jenko","given":"Kathryn","email":"","affiliations":[],"preferred":false,"id":353685,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Balk, Lennart","contributorId":38844,"corporation":false,"usgs":true,"family":"Balk","given":"Lennart","affiliations":[],"preferred":false,"id":353689,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Skarphedinsdottir, Halldora","contributorId":52832,"corporation":false,"usgs":true,"family":"Skarphedinsdottir","given":"Halldora","email":"","affiliations":[],"preferred":false,"id":353690,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Liewenborg, Birgitta","contributorId":101940,"corporation":false,"usgs":true,"family":"Liewenborg","given":"Birgitta","email":"","affiliations":[],"preferred":false,"id":353692,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Rutter, Michael A.","contributorId":13938,"corporation":false,"usgs":true,"family":"Rutter","given":"Michael","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":353686,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Predation and other interactions with nonnative rainbow trout and brown trout have been hypothesized as contributing to the decline of native fishes (including the endangered humpback chub <i>Gila cypha</i>) in the Colorado River, Grand Canyon. A multiyear study was conducted to remove nonnative fish from a 15-km segment of the Colorado River near the Little Colorado River confluence. We evaluated how sediment, temperature, fish prey availability, and predator abundance influenced the incidence of piscivory (IP) by nonnative salmonids. Study objectives were addressed through spatial (upstream and downstream of the Little Colorado River confluence) and temporal (seasonal and annual) comparisons of prey availability and predator abundance. Data were then evaluated by modeling the quantity of fish prey ingested by trout during the first 2 years (2003&ndash;2004) of the mechanical removal period. Field effort resulted in the capture of 20,000 nonnative fish, of which 90% were salmonids. Results indicated that the brown trout IP was higher (8&ndash;70%) than the rainbow trout IP (0.5&ndash;3.3%); however, rainbow trout were 50 times more abundant than brown trout in the study area. We estimated that during the study period, over 30,000 fish (native and nonnative species combined) were consumed by rainbow trout (21,641 fish) and brown trout (11,797 fish). On average, rainbow trout and brown trout ingested 85% more native fish than nonnative fish in spite of the fact that native fish constituted less than 30% of the small fish available in the study area. Turbidity may mediate piscivory directly by reducing prey detection, but this effect was not apparent in our data, as rainbow trout IP was greater when suspended sediment levels (range = 5.9&ndash;20,000 mg/L) were higher.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Talor & Francis","publisherLocation":"Philadelphia, PA","doi":"10.1080/00028487.2011.572011","usgsCitation":"Yard, M., Coggins, Baxter, C., Bennett, G., and Korman, J., 2011, Trout piscivory in the Colorado River, Grand Canyon: Effects of turbidity, temperature, and fish prey availability: Transactions of the American Fisheries Society, v. 140, no. 2, p. 471-486, https://doi.org/10.1080/00028487.2011.572011.","productDescription":"16 p.","startPage":"471","endPage":"486","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":204579,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":21753,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1080/00028487.2011.572011","linkFileType":{"id":5,"text":"html"}}],"volume":"140","issue":"2","noUsgsAuthors":false,"publicationDate":"2011-04-13","publicationStatus":"PW","scienceBaseUri":"505bb89de4b08c986b327977","contributors":{"authors":[{"text":"Yard, Michael D. 0000-0002-6580-6027","orcid":"https://orcid.org/0000-0002-6580-6027","contributorId":8577,"corporation":false,"usgs":true,"family":"Yard","given":"Michael D.","affiliations":[],"preferred":false,"id":349685,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Coggins, Jr.","contributorId":54306,"corporation":false,"usgs":true,"family":"Coggins","suffix":"Jr.","email":"","affiliations":[],"preferred":false,"id":349688,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Baxter, Colden V.","contributorId":47334,"corporation":false,"usgs":false,"family":"Baxter","given":"Colden V.","affiliations":[{"id":13656,"text":"Idaho State Univ.","active":true,"usgs":false}],"preferred":false,"id":349687,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bennett, Glenn E. gbennett@usgs.gov","contributorId":4153,"corporation":false,"usgs":true,"family":"Bennett","given":"Glenn E.","email":"gbennett@usgs.gov","affiliations":[],"preferred":true,"id":349684,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Korman, Josh","contributorId":29922,"corporation":false,"usgs":true,"family":"Korman","given":"Josh","affiliations":[],"preferred":false,"id":349686,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

To understand its effects on the parasites of aquatic organisms, we analyzed long-term monthly population data of the horn snail <i>Cerithidea pliculosa</i> and its trematode communities in Celest&#250;n, Yucat&#225;n, Mexico before and after the hurricane (February 2001 to December 2009). Five trematode species occurred in the snail population: <i>Mesostephanus appendiculatoides</i>, <i>Euhaplorchis californiensis</i>, two species of the genus <i>Renicola</i> and one Heterophyidae gen. sp. Because these parasites use snails as first intermediate hosts, fishes as second intermediate hosts and birds as final hosts, their presence in snails depends on food webs. No snails were present at the sampled sites for 6 months after the hurricane. After snails recolonised the site, no trematodes were found in snails until 14 months after the hurricane. It took several years for snail and trematode populations to recover. Our results suggest that the increase in the occurrence of hurricanes predicted due to climate change can impact upon parasites with complex life cycles. However, both the snail populations and their parasite communities eventually reached numbers of individuals and species similar to those before the hurricane. Thus, the trematode parasites of snails can be useful indicators of coastal lagoon ecosystem degradation and recovery.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"International Journal for Parasitology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.ijpara.2011.10.002","usgsCitation":"Aguirre-Macedo, M.L., Vidal-Martinez, V., and Lafferty, K.D., 2011, Trematode communities in snails can indicate impact and recovery from hurricanes in a tropical coastal lagoon: International Journal for Parasitology, v. 41, no. 13-14, p. 1403-1408, https://doi.org/10.1016/j.ijpara.2011.10.002.","productDescription":"6 p.","startPage":"1403","endPage":"1408","numberOfPages":"6","temporalStart":"2001-02-01","temporalEnd":"2009-12-31","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":204703,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":115688,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1016/j.ijpara.2011.10.002","linkFileType":{"id":5,"text":"html"}}],"country":"Mexico","volume":"41","issue":"13-14","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb7ace4b08c986b327402","contributors":{"authors":[{"text":"Aguirre-Macedo, Maria Leopoldina","contributorId":21424,"corporation":false,"usgs":true,"family":"Aguirre-Macedo","given":"Maria","email":"","middleInitial":"Leopoldina","affiliations":[],"preferred":false,"id":353873,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Vidal-Martinez, Victor M.","contributorId":106382,"corporation":false,"usgs":true,"family":"Vidal-Martinez","given":"Victor M.","affiliations":[],"preferred":false,"id":353874,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lafferty, Kevin D. 0000-0001-7583-4593 klafferty@usgs.gov","orcid":"https://orcid.org/0000-0001-7583-4593","contributorId":1415,"corporation":false,"usgs":true,"family":"Lafferty","given":"Kevin","email":"klafferty@usgs.gov","middleInitial":"D.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":353872,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The greatest forest floor accumulations of C, N, P, Ca, Mg, and K occurred under Douglas-fir, primarily due to greater forest floor mass. In mineral soil, western hemlock exhibited significantly lower Ca concentration and sum of cations (Ca + Mg + K) than bigleaf maple, with intermediate values for Douglas-fir and western redcedar. Bigleaf maple explained most species-based differences in foliar nutrients, displaying high concentrations of N, P, Ca, Mg, and K. Foliar P and N:P variations largely reflected soil P variation across sites. The four tree species that we examined exhibited a number of individualistic effects on soil nutrient levels that contribute to biogeochemical heterogeneity in these ecosystems. Where fire suppression and long-term succession favor dominance by highly shade-tolerant western hemlock, our results suggest a potential for declines in both soil Ca availability and soil biogeochemical heterogeneity in old-growth forests.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Forest Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Canadian Science Publishing","publisherLocation":"Ottawa, Ontario","doi":"10.1139/X10-199","usgsCitation":"Cross, A., and Perakis, S., 2011, Tree species and soil nutrient profiles in old-growth forests of the Oregon Coast Range: Canadian Journal of Forest Research, v. 41, no. 1, p. 195-210, https://doi.org/10.1139/X10-199.","productDescription":"16 p.","startPage":"195","endPage":"210","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":204704,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":115687,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1139/X10-199","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Oregon","volume":"41","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb7a2e4b08c986b3273b9","contributors":{"authors":[{"text":"Cross, Alison","contributorId":28730,"corporation":false,"usgs":false,"family":"Cross","given":"Alison","email":"","affiliations":[],"preferred":false,"id":348668,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Perakis, Steven S. 0000-0003-0703-9314","orcid":"https://orcid.org/0000-0003-0703-9314","contributorId":16797,"corporation":false,"usgs":true,"family":"Perakis","given":"Steven S.","affiliations":[],"preferred":false,"id":348667,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Batch and column experiments were conducted to investigate the factors controlling U(VI) adsorption/desorption by changing chemical conditions over time. Low alkalinity and low Ca concentrations (Columbia River water) enhanced adsorption and reduced aqueous concentrations. Conversely, high alkalinity and high Ca concentrations (Hanford groundwater) reduced adsorption and increased aqueous concentrations of U(VI). An equilibrium surface complexation model calibrated using laboratory batch experiments accounted for the decrease in U(VI) adsorption observed with increasing (bi)carbonate concentrations and other aqueous chemical conditions. In the column experiment, alternating pulses of river and groundwater caused swings in aqueous U(VI) concentration. A multispecies multirate surface complexation reactive transport model simulated most of the major U(VI) changes in two column experiments. The modeling results also indicated that U(VI) transport in the studied sediment could be simulated by using a single kinetic rate without loss of accuracy in the simulations. Moreover, the capability of the model to predict U(VI) transport in Hanford groundwater under transient chemical conditions depends significantly on the knowledge of real-time change of local groundwater chemistry.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/2010WR009369","usgsCitation":"Yin, J., Haggerty, R., Stoliker, D., Kent, D.B., Istok,

In order to decipher influences on trace element incorporation and sulfur isotope composition, crystalline and colloform sphalerite from the carbonate-hosted Mississippi-Valley Type (MVT) deposit near Wiesloch, SW Germany, were investigated and compared to sphalerite samples from 52 hydrothermal vein-type deposits in the Schwarzwald ore district, SW Germany to study the influence of different host rocks, formation mechanisms and fluid origin on trace element incorporation. Trace and minor element incorporation in sphalerite shows some correlation to their host rock and/or origin of fluid, gangue, paragenetic minerals and precipitation mechanisms (e.g., diagenetic processes, fluid cooling or fluid mixing). Furthermore, crystalline sphalerite is generally enriched in elements like Cd, Cu, Sb and Ag compared to colloform sphalerite that mainly incorporates elements like As, Pb and Tl. In addition, sulfur isotopes are characterized by positive values for crystalline and strongly negative values for colloform sphalerite. The combination of trace element contents, typical minerals associated with colloform sphalerite from Wiesloch, sulfur isotopes and thermodynamic considerations helped to evaluate the involvement of sulfate-reducing bacteria in water-filled karst cavities. Sulfate-reducing bacteria cause a sulfide-rich environment that leads in case of a metal-rich fluid supply to a sudden oversaturation of the fluid with respect to galena, sphalerite and pyrite. This, however, exactly coincides with the observed crystallization sequence of samples involving colloform sphalerite from the Wiesloch MVT deposit.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Chemical Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.chemgeo.2011.04.018","usgsCitation":"Pfaff, K., Koenig, A., Wenzel, T., Ridley, I., Hildebrandt, L.H., Leach, D.L., and Markl, G., 2011, Trace and minor element variations and sulfur isotopes in crystalline and colloform ZnS: Incorporation mechanisms and implications for their genesis: Chemical Geology, v. 286, no. 3-4, p. 118-134, https://doi.org/10.1016/j.chemgeo.2011.04.018.","productDescription":"17 p.","startPage":"118","endPage":"134","numberOfPages":"17","costCenters":[{"id":171,"text":"Central Mineral and Environmental Resources Science Center","active":true,"usgs":true}],"links":[{"id":204575,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":115675,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://dx.doi.org/10.1016/j.chemgeo.2011.04.018","linkFileType":{"id":5,"text":"html"}}],"country":"Germany","city":"Wiesloch","volume":"286","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb630e4b08c986b326af6","contributors":{"authors":[{"text":"Pfaff, Katharina","contributorId":49916,"corporation":false,"usgs":true,"family":"Pfaff","given":"Katharina","affiliations":[],"preferred":false,"id":351441,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Koenig, Alan 0000-0002-5230-0924","orcid":"https://orcid.org/0000-0002-5230-0924","contributorId":63159,"corporation":false,"usgs":true,"family":"Koenig","given":"Alan","affiliations":[],"preferred":false,"id":351442,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wenzel, Thomas","contributorId":12975,"corporation":false,"usgs":true,"family":"Wenzel","given":"Thomas","email":"","affiliations":[],"preferred":false,"id":351439,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Ridley, Ian","contributorId":23244,"corporation":false,"usgs":true,"family":"Ridley","given":"Ian","email":"","affiliations":[],"preferred":false,"id":351440,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hildebrandt, Ludwig H.","contributorId":101375,"corporation":false,"usgs":true,"family":"Hildebrandt","given":"Ludwig","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":351445,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Leach, David L.","contributorId":83902,"corporation":false,"usgs":true,"family":"Leach","given":"David","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":351444,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Markl, Gregor","contributorId":73732,"corporation":false,"usgs":true,"family":"Markl","given":"Gregor","email":"","affiliations":[],"preferred":false,"id":351443,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

When released into an aquatic environment, SiCNW would likely accumulate in sediment. The objective of this study was to assess the toxicity of SiCNW to four freshwater sediment-dwelling organisms: amphipods (<i>Hyalella azteca</i>), midges (<i>Chironomus dilutus</i>), oligochaetes (<i>Lumbriculus variegatus</i>), and mussels (<i>Lampsilis siliquoidea</i>). Amphipods were exposed to either sonicated or nonsonicated SiCNW in water (1.0 g/L) for 48 h. Midges, mussels, and oligochaetes were exposed only to sonicated SiCNW in water for 96 h. In addition, amphipods were exposed to sonicated SiCNW in whole sediment for 10 d (44% SiCNW on dry wt basis). Mean 48-h survival of amphipods exposed to nonsonicated SiCNW in water was not significantly different from the control, whereas mean survival of amphipods exposed to sonicated SiCNW in two 48-h exposures (0 or 15% survival) was significantly different from the control (90 or 98% survival). In contrast, no effect of sonicated SiCNW was observed on survival of midges, mussels, or oligochaetes. Survival of amphipods was not significantly reduced in 10-d exposures to sonicated SiCNW either mixed in the sediment or layered on the sediment surface. However, significant reduction in amphipod biomass was observed with the SiCNW either mixed in sediment or layered on the sediment surface, and the reduction was more pronounced for SiCNW layered on the sediment. These results indicated that, under the experimental conditions, nonsonicated SiCNW in water were not acutely toxic to amphipods, sonicated SiCNW in water were acutely toxic to the amphipods, but not to other organisms tested, and sonicated SiCNW in sediment affected the growth but not the survival of amphipods.","language":"English","publisher":"Wiley","doi":"10.1002/etc.467","usgsCitation":"Mwangi, J.N., Wang, N., Ritts, A., Kunz, J.L., Ingersoll, C.G., Li, H., and Deng, B., 2011, Toxicity of silicon carbide nanowires to sediment-dwelling invertebrates in water or sediment exposures: Environmental Toxicology and Chemistry, v. 30, no. 4, p. 981-987, https://doi.org/10.1002/etc.467.","productDescription":"7 p.","startPage":"981","endPage":"987","numberOfPages":"7","costCenters":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true},{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":204573,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"30","issue":"4","noUsgsAuthors":false,"publicationDate":"2011-04-01","publicationStatus":"PW","scienceBaseUri":"505bb615e4b08c986b326a56","contributors":{"authors":[{"text":"Mwangi, Joseph N.","contributorId":70535,"corporation":false,"usgs":true,"family":"Mwangi","given":"Joseph","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":349304,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wang, Ning 0000-0002-2846-3352 nwang@usgs.gov","orcid":"https://orcid.org/0000-0002-2846-3352","contributorId":2818,"corporation":false,"usgs":true,"family":"Wang","given":"Ning","email":"nwang@usgs.gov","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":349299,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ritts, Andrew","contributorId":54338,"corporation":false,"usgs":true,"family":"Ritts","given":"Andrew","email":"","affiliations":[],"preferred":false,"id":349303,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kunz, James L. 0000-0002-1027-158X jkunz@usgs.gov","orcid":"https://orcid.org/0000-0002-1027-158X","contributorId":3309,"corporation":false,"usgs":true,"family":"Kunz","given":"James","email":"jkunz@usgs.gov","middleInitial":"L.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":349300,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ingersoll, Christopher G. 0000-0003-4531-5949 cingersoll@usgs.gov","orcid":"https://orcid.org/0000-0003-4531-5949","contributorId":2071,"corporation":false,"usgs":true,"family":"Ingersoll","given":"Christopher","email":"cingersoll@usgs.gov","middleInitial":"G.","affiliations":[{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":349298,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Li, Hao","contributorId":14945,"corporation":false,"usgs":true,"family":"Li","given":"Hao","affiliations":[],"preferred":false,"id":349302,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Deng, Baolin","contributorId":8988,"corporation":false,"usgs":true,"family":"Deng","given":"Baolin","email":"","affiliations":[],"preferred":false,"id":349301,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Nestlings received various diets, including 0 (control), 0.6, and 3.9 &mu;g/g (dry wt) MeHg for up to 18 d posthatch. Immunotoxicity endpoints included cell-mediated immunity (CMI) using the phytohemagglutinin (PHA) skin-swelling assay and antibody-mediated immune response via the sheep red blood cell (SRBC) hemagglutination assay. T cell&ndash; and B cell&ndash;dependent histological parameters in the spleen, thymus, and bursa of Fabricius were correlated with the functional assays. For nestlings in the 0.6 and 3.9 &mu;g/g MeHg groups, CMI was suppressed by 73 and 62%, respectively, at 11 d of age. Results of this functional assay were correlated with T cell&ndash;dependent components of the spleen and thymus. Dose-dependent lymphoid depletion in spleen tissue directly affected the proliferation of T-lymphocyte populations, insofar as lower stimulation indexes from the PHA assay occurred in nestlings with lower proportions of splenic white pulp and higher THg concentrations. Nestlings in the 3.9 &mu;g/g group also exhibited lymphoid depletion and a lack of macrophage activity in the thymus. Methylmercury did not have a noticeable effect on antibody-mediated immune function or B cell&ndash;dependent histological correlates. We conclude that T cell&ndash;mediated immunosuppression is the primary target of MeHg toward adaptive immunity in developing kestrels. This study provides evidence that environmentally relevant concentrations of MeHg may compromise immunocompetence in a developing terrestrial predator and raises concern regarding the long-term health effects of kestrels that were exposed to dietary MeHg during early avian development.","language":"English","publisher":"Society of Environmental Toxicology and Chemistry","publisherLocation":"Brussels, Belgium","doi":"10.1002/etc.519","usgsCitation":"Fallacara, D.M., Halbrook, R.S., and French, J.B., 2011, Toxic effects of dietary methylmercury on immune system development in nestling American kestrels (<i>Falco sparverius</i>): Environmental Toxicology and Chemistry, v. 30, no. 6, p. 1328-1337, https://doi.org/10.1002/etc.519.","productDescription":"10 p.","startPage":"1328","endPage":"1337","numberOfPages":"10","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true},{"id":34983,"text":"Contaminant Biology Program","active":true,"usgs":true}],"links":[{"id":204574,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"30","issue":"6","noUsgsAuthors":false,"publicationDate":"2011-06-01","publicationStatus":"PW","scienceBaseUri":"505bb5c8e4b08c986b3268d3","contributors":{"authors":[{"text":"Fallacara, Dawn M.","contributorId":77295,"corporation":false,"usgs":true,"family":"Fallacara","given":"Dawn","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":351293,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Halbrook, Richard S.","contributorId":12974,"corporation":false,"usgs":true,"family":"Halbrook","given":"Richard","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":351292,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"French, John B. 0000-0001-8901-7092 jbfrench@usgs.gov","orcid":"https://orcid.org/0000-0001-8901-7092","contributorId":377,"corporation":false,"usgs":true,"family":"French","given":"John","email":"jbfrench@usgs.gov","middleInitial":"B.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":351291,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

However, pond ash is known to have high concentrations of trace elements, and the runoff water-quality effects of feedlot surfaces amended with pond ash are not well defined. For this study, two experimental units (plots) were established in eight feedlot pens. Four of the pens contained unamended soil surfaces, and the remaining four pens had pond-ash amended surfaces. Before each test, unconsolidated surface material was removed from four of the plots for each of the amendment treatments, resulting in eight unamended plots and eight pond-ash amended plots. Concentrations for 23 trace elements were measured in cattle feedlot surface material and in the runoff water from three simulated rainfall events. Trace element concentrations in surface material and runoff did not differ between surface consolidation treatments. Amending the feedlot surface material with pond ash resulted in a significant increase in concentration for 14 of the 17 trace elements. Runoff concentrations for 21 trace elements were affected by pond-ash amendment. Sixteen of 21 trace element concentrations that differed significantly were greater in runoff from unamended soil surfaces. Concentrations in runoff were significantly correlated with concentrations in feedlot surface material for boron, manganese, molybdenum, selenium, and uranium.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the ASABE","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Society of Agricultural and Biological Engineers","publisherLocation":"St. Joseph, MI","usgsCitation":"Vogel, J.R., Gilley, J., Cottrell, G., Woodbury, B., Berry, E., and Eigenbert, R., 2011, Transport of trace metals in runoff from soil and pond ash feedlot surfaces: Transactions of the ASABE, v. 54, no. 4, p. 1269-1279.","productDescription":"11 p.","startPage":"1269","endPage":"1279","costCenters":[{"id":464,"text":"Nebraska Water Science Center","active":true,"usgs":true}],"links":[{"id":204700,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":115686,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://www.ars.usda.gov/SP2UserFiles/Place/54380530/2011541269.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Nebraska","county":"Clay","volume":"54","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb758e4b08c986b3271ec","contributors":{"authors":[{"text":"Vogel, J.

All the authors were workshop participants.</p>\n<p><b>Objectives</b> Our aim was to initiate a dynamic, adaptable process for identifying contaminants of emerging concern (CECs) that are likely to be found in future hazardous waste sites, and to identify the gaps in primary research that cause uncertainty in determining future hazardous waste site contaminants.</p>\n<p><b>Discussion</b> Superfund-relevant CECs can be characterized by specific attributes: They are persistent, bioaccumulative, toxic, occur in large quantities, and have localized accumulation with a likelihood of exposure. Although still under development and incompletely applied, methods to quantify these attributes can assist in winnowing down the list of candidates from the universe of potential CECs. Unfortunately, significant research gaps exist in detection and quantification, environmental fate and transport, health and risk assessment, and site exploration and remediation for CECs. Addressing these gaps is prerequisite to a preventive approach to generating and managing hazardous waste sites.</p>\n<p><b>Conclusions</b> A need exists for a carefully considered and orchestrated expansion of programmatic and research efforts to identify, evaluate, and manage CECs of hazardous waste site relevance, including developing an evolving list of priority CECs, intensifying the identification and monitoring of likely sites of present or future accumulation of CECs, and implementing efforts that focus on a holistic approach to prevention.</p>","language":"English","publisher":"National Institute of Environmental Health Sciences","doi":"10.1289/ehp.1002497","usgsCitation":"Ela, W.P., Sedlak, D.L., Barlaz, M.A., Henry, H.F., Muir, D.C., Swackhamer, D.L., Weber, E.J., Arnold, R.G., Ferguson, P.L., Field, J.A., Furlong, E.T., Giesy, J.P., Halden, R.U., Henry, T., Hites, R., Hornbuckle, K.C., Howard, P.H., Luthy, R.G., Meyer, A.K., Saez, A.E., vom Saal, F., Vulpe, C.D., and Wiesner, M.R., 2011, Towards identifying the next generation of superfund and hazardous waste site contaminants: Environmental Health Perspectives, v. 119, no. 1, p. 6-10, https://doi.org/10.1289/ehp.1002497.","productDescription":"5 p.","startPage":"6","endPage":"10","costCenters":[{"id":140,"text":"Branch of Analytical Serv (National Water Quality Laboratory)","active":false,"usgs":true},{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":474781,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1289/ehp.1002497","text":"Publisher Index Page"},{"id":204593,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"119","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb5bfe4b08c986b32688f","contributors":{"authors":[{"text":"Ela, Wendell P.","contributorId":96543,"corporation":false,"usgs":true,"family":"Ela","given":"Wendell","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":347797,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sedlak, David L.","contributorId":20613,"corporation":false,"usgs":true,"family":"Sedlak","given":"David","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":347783,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Barlaz, Morton A.","contributorId":68174,"corporation":false,"usgs":true,"family":"Barlaz","given":"Morton","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":347790,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Henry, Heather F.","contributorId":18231,"corporation":false,"usgs":true,"family":"Henry","given":"Heather","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":347781,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Muir, Derek C.G.","contributorId":68679,"corporation":false,"usgs":true,"family":"Muir","given":"Derek","email":"","middleInitial":"C.G.","affiliations":[],"preferred":false,"id":347791,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Swackhamer, Deborah L.","contributorId":96544,"corporation":false,"usgs":true,"family":"Swackhamer","given":"Deborah","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":347798,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Weber, Eric J.","contributorId":93345,"corporation":false,"usgs":true,"family":"Weber","given":"Eric","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":347795,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Arnold, Robert G.","contributorId":95336,"corporation":false,"usgs":true,"family":"Arnold","given":"Robert","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":347796,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Ferguson, P.

Millions of birds visit wetlands across the country, yet information on their distribution, abundance, and use of resources is rudimentary at best. Limited information suggests that populations of several species of migratory ducks are declining due to encroachment of wetland habitats largely by agriculture and industry. The development of conservation strategies is stymied by a lack of ecological information on these species. We conducted a preliminary assessment of the home range and habitat use of Ruddy Shelduck <i>Tadorna ferruginea</i> in the northeast Indian state of Assam. Seven Ruddy Shelducks were fitted with solar-powered Global Positioning System (GPS) satellite transmitters, and were tracked on a daily basis during the winter of 2009-2010. Locations from all seven were used to describe habitat use, while locations from four were used to quantify their home range, as the other three had too few locations (< 30) for home range estimation. A Brownian Bridge Movement Model (BBMM), used to estimate home ranges, found that the Ruddy Shelduck had an average core use area (i.e. the contour defining 50% of positions) of 40 km<sup>2</sup> (range = 22-87 km<sup>2</sup>) and an average home range (95% contour) of 610 km<sup>2</sup> (range = 222-1,550 km<sup>2</sup>). Resource Selection Functions (RSF), used to describe habitat use, showed that the birds frequented riverine wetlands more than expected, occurred on grasslands and shrublands in proportion to their availability, and avoided woods and cropland habitats. The core use areas for three individuals (75%) were on the Brahmaputra River, indicating their preference for riverine habitats. Management and protection of riverine habitats and nearby grasslands may benefit conservation efforts for the Ruddy Shelduck and waterfowl species that share these habitats during the non-breeding season.","language":"English","publisher":"Wildfowl & Wetlands Trust","publisherLocation":"Slimbridge, Gloucestershire","usgsCitation":"Namgail, T., Takekawa, J.Y., Sivananinthaperumal, B., Areendran, G., Sathiyaselvam, P., Mundkur, T., Mccracken, T., and Newman, S., 2011, Ruddy Shelduck <i>Tadorna ferruginea</i> home range and habitat use during the non-breeding season in Assam, India: Wildfowl, v. 61, p. 182-193.","productDescription":"12 p.","startPage":"182","endPage":"193","temporalStart":"2009-12-22","temporalEnd":"2010-03-21","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":328995,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://wildfowl.wwt.org.uk/index.php/wildfowl/article/view/1243"},{"id":204590,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"India","state":"Assam","volume":"61","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaeb6e4b0c8380cd8719e","contributors":{"authors":[{"text":"Namgail, T.","contributorId":72526,"corporation":false,"usgs":true,"family":"Namgail","given":"T.","affiliations":[],"preferred":false,"id":355910,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Takekawa, John Y. 0000-0003-0217-5907 john_takekawa@usgs.gov","orcid":"https://orcid.org/0000-0003-0217-5907","contributorId":176168,"corporation":false,"usgs":true,"family":"Takekawa","given":"John","email":"john_takekawa@usgs.gov","middleInitial":"Y.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":355909,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sivananinthaperumal, B.","contributorId":96006,"corporation":false,"usgs":true,"family":"Sivananinthaperumal","given":"B.","affiliations":[],"preferred":false,"id":355912,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Areendran, G.","contributorId":79620,"corporation":false,"usgs":true,"family":"Areendran","given":"G.","email":"","affiliations":[],"preferred":false,"id":355911,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Sathiyaselvam, P.","contributorId":51015,"corporation":false,"usgs":true,"family":"Sathiyaselvam","given":"P.","affiliations":[],"preferred":false,"id":355907,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mundkur, T.","contributorId":60151,"corporation":false,"usgs":true,"family":"Mundkur","given":"T.","affiliations":[],"preferred":false,"id":355908,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Mccracken, T.","contributorId":25697,"corporation":false,"usgs":true,"family":"Mccracken","given":"T.","email":"","affiliations":[],"preferred":false,"id":355906,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Newman, S.","contributorId":7678,"corporation":false,"usgs":true,"family":"Newman","given":"S.","affiliations":[],"preferred":false,"id":355905,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}
