Out of the 33 target mycotoxins measured, nine were detected at least once during this study. The detections of mycotoxins were nearly ubiquitous during this study even though the basin size spanned four orders of magnitude. At least one mycotoxin was detected in 94% of the 116 samples collected. Deoxynivalenol was the most frequently detected mycotoxin (77%), followed by nivalenol (59%), beauvericin (43%), zearalenone (26%), β-zearalenol (20%), 3-acetyl-deoxynivalenol (16%), α-zearalenol (10%), diacetoxyscirpenol (5%), and verrucarin A (1%). In addition, one or more of the three known estrogenic compounds (i.e. zearalenone, α-zearalenol, and β-zearalenol) were detected in 43% of the samples, with maximum concentrations substantially higher than observed in previous research. While concentrations were generally low (i.e. < 50 ng/L) during this study, concentrations exceeding 1000 ng/L were measured during spring snowmelt conditions in agricultural settings and in wastewater treatment plant effluent. Results of this study suggest that both diffuse (e.g. release from infected plants and manure applications from exposed livestock) and point (e.g. wastewater treatment plants and food processing plants) sources are important environmental pathways for mycotoxin transport to streams.

Attenuation at distances from 10 to 500 km may be adequately described using a bilinear model with a geometric spreading of 1/R<sup>1.3</sup> to a transition distance of 50 km, with a geometric spreading of 1/R<sup>0.5</sup> at greater distances. For low frequencies and distances less than 50 km, the effective geometric spreading given by the model is perturbed using a frequency‐ and hypocentral depth‐dependent factor defined in such a way as to increase amplitudes at lower frequencies near the epicenter but leave the 1 km source amplitudes unchanged. The associated anelastic attenuation is determined for each event, with an average value being given by a regional quality factor of Q=525f<sup> 0.45</sup>. This model provides a match, on average, between the known seismic moment of events and the inferred low‐frequency spectral amplitudes at R=1  km (obtained by correcting for the attenuation model). The inferred Brune stress parameters from the high‐frequency source terms are about 600 bars (60 MPa), on average, for events of M>4.5.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Seismological Society of America","doi":"10.1785/0120130136","usgsCitation":"Atkinson, G.M., and Boore, D.M., 2014, The attenuation of Fourier amplitudes for rock sites in eastern North America: Bulletin of the Seismological Society of America, v. 104, no. 1, p. 513-528, https://doi.org/10.1785/0120130136.","productDescription":"16 p.","startPage":"513","endPage":"528","numberOfPages":"16","ipdsId":"IP-046179","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":280963,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280961,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120130136"},{"id":280964,"type":{"id":15,"text":"Index Page"},"url":"https://www.bssaonline.org/content/early/2013/11/25/0120130136"}],"country":"Canada;United States","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -90.0,34.0 ], [ -90.0,54.0 ], [ -55.0,54.0 ], [ -55.0,34.0 ], [ -90.0,34.0 ] ] ] } } ] }","volume":"104","issue":"1","noUsgsAuthors":false,"publicationDate":"2013-11-26","publicationStatus":"PW","scienceBaseUri":"53cd776be4b0b2908510b889","contributors":{"authors":[{"text":"Atkinson, Gail M.","contributorId":60515,"corporation":false,"usgs":false,"family":"Atkinson","given":"Gail","email":"","middleInitial":"M.","affiliations":[{"id":13255,"text":"University of Western Ontario","active":true,"usgs":false}],"preferred":false,"id":484394,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Boore, David M. boore@usgs.gov","contributorId":2509,"corporation":false,"usgs":true,"family":"Boore","given":"David","email":"boore@usgs.gov","middleInitial":"M.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"preferred":false,"id":484393,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

This need is particularly important in studies where detection and/or capture probability is influenced by parasite-induced behavioral alterations. We assessed potential biases associated with sampling a population of the amphipod Gammarus lacustris in the presence of Polymorphus spp. acanthocephalan parasites shown to increase positive phototaxis in their amphipod hosts. We trapped G. lacustris at two water depths (benthic and surface) and compared number of captures and number of parasitized individuals at each depth. While we captured the greatest number of G. lacustris individuals in benthic traps, parasitized individuals were captured most often in surface traps. These results reflect the phototaxic movement of infected individuals from benthic locations to sunlit surface waters. We then explored the influence of varying infection rates on a simulated population held at a constant level of abundance. Simulations resulted in increasingly biased abundance estimates as infection rates increased. Our results highlight the need to consider parasite-induced biases when quantifying detection and/or capture probability in studies of aquatic invertebrate populations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Hydrobiologia","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s10750-013-1700-9","usgsCitation":"Fisher, J.D., Mushet, D.M., and Stockwell, C., 2014, Potential for parasite-induced biases in aquatic invertebrate population studies: Hydrobiologia, v. 722, no. 1, p. 199-204, https://doi.org/10.1007/s10750-013-1700-9.","productDescription":"6 p.","startPage":"199","endPage":"204","ipdsId":"IP-041710","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":279315,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":279301,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10750-013-1700-9"}],"country":"United States","state":"North Dakota","county":"Stutsman County","otherGeospatial":"Cottonwood Lakes Study Area","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -99.48275,46.629387 ], [ -99.48275,47.327213 ], [ -98.439552,47.327213 ], [ -98.439552,46.629387 ], [ -99.48275,46.629387 ] ] ] } } ] }","volume":"722","issue":"1","noUsgsAuthors":false,"publicationDate":"2013-10-10","publicationStatus":"PW","scienceBaseUri":"528f53cce4b0660d392bed7e","contributors":{"authors":[{"text":"Fisher, Justin D.L.","contributorId":32817,"corporation":false,"usgs":true,"family":"Fisher","given":"Justin","email":"","middleInitial":"D.L.","affiliations":[],"preferred":false,"id":486610,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mushet, David M. 0000-0002-5910-2744 dmushet@usgs.gov","orcid":"https://orcid.org/0000-0002-5910-2744","contributorId":1299,"corporation":false,"usgs":true,"family":"Mushet","given":"David","email":"dmushet@usgs.gov","middleInitial":"M.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":486609,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stockwell, Craig A.","contributorId":55257,"corporation":false,"usgs":true,"family":"Stockwell","given":"Craig A.","affiliations":[],"preferred":false,"id":486611,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In this study, we compared the body size, condition, and recruitment of polar bears captured in the Chukchi and Bering Seas (CS) between two periods (1986–1994 and 2008–2011) when declines in sea ice habitat occurred. In addition, we compared metrics for the CS population 2008–2011 with those of the adjacent southern Beaufort Sea (SB) population where loss in sea ice habitat has been associated with declines in body condition, size, recruitment, and survival. We evaluated how variation in body condition and recruitment were related to feeding ecology. Comparing habitat conditions between populations, there were twice as many reduced ice days over continental shelf waters per year during 2008–2011 in the SB than in the CS. CS polar bears were larger and in better condition, and appeared to have higher reproduction than SB bears. Although SB and CS bears had similar diets, twice as many bears were fasting in spring in the SB than in the CS. Between 1986–1994 and 2008–2011, body size, condition, and recruitment indices in the CS were not reduced despite a 44-day increase in the number of reduced ice days. Bears in the CS exhibited large body size, good body condition, and high indices of recruitment compared to most other populations measured to date. Higher biological productivity and prey availability in the CS relative to the SB, and a shorter recent history of reduced sea ice habitat, may explain the maintenance of condition and recruitment of CS bears.

Classical groundwater-resource issues exist (magnitude and lateral extent of drawdown near pumping centers) with joint international management questions regarding transboundary drawdown. Much of NAS is thick, containing a large volume of high-quality groundwater, but receives insignificant recharge, so water-resource availability is time-limited. Informative aquifer data are lacking regarding large-scale response, providing only local-scale information near pumps. Proxy data provide primary underpinning for understanding regional response: Holocene water-table decline from the previous pluvial period, after thousands of years, results in current oasis/sabkha locations where the water table still intersects the ground. Depletion is found to be controlled by two regional parameters, hydraulic diffusivity and vertical anisotropy of permeability. Secondary data that provide insight are drawdowns near pumps and isotope-groundwater ages (million-year-old groundwaters in Egypt). The resultant strong simply structured three-dimensional model representation captures the essence of NAS regional groundwater-flow behavior. Model forecasts inform resource management that transboundary drawdown will likely be minimal—a nonissue—whereas drawdown within pumping centers may become excessive, requiring alternative extraction schemes; correspondingly, significant water-table drawdown may occur in pumping centers co-located with oases, causing oasis loss and environmental impacts.","language":"English","publisher":"Springer","doi":"10.1007/s10040-013-1039-3","usgsCitation":"Voss, C.I., and Soliman, S.M., 2014, The transboundary non-renewable Nubian Aquifer System of Chad, Egypt, Libya and Sudan: Classical groundwater questions and parsimonious hydrogeologic analysis and modeling: Hydrogeology Journal, v. 22, no. 2, p. 441-468, https://doi.org/10.1007/s10040-013-1039-3.","productDescription":"28 p.","startPage":"441","endPage":"468","ipdsId":"IP-046054","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"links":[{"id":281011,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Chad, Egypt, Libya, Sudan","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 9.39,7.44 ], [ 9.39,33.29 ], [ 38.7,33.29 ], [ 38.7,7.44 ], [ 9.39,7.44 ] ] ] } } ] }","volume":"22","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-11-06","publicationStatus":"PW","scienceBaseUri":"53cd78b6e4b0b2908510c543","contributors":{"authors":[{"text":"Voss, Clifford I. 0000-0001-5923-2752 cvoss@usgs.gov","orcid":"https://orcid.org/0000-0001-5923-2752","contributorId":1559,"corporation":false,"usgs":true,"family":"Voss","given":"Clifford","email":"cvoss@usgs.gov","middleInitial":"I.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":479646,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Soliman, Safaa M.","contributorId":52078,"corporation":false,"usgs":true,"family":"Soliman","given":"Safaa","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":479647,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

For the Laurentian Great Lakes, where, since the early 1970s, nutrient inputs have been reduced, whereas top-predator biomass has increased, we describe trends across multiple trophic levels and explore their underlying drivers. Our analyses revealed increasing water clarity and declines in phytoplankton, native invertebrates, and prey fish since 1998 in at least three of the five lakes. Evidence for bottom-up regulation was strongest in Lake Huron, although each lake provided support in at least one pair of trophic levels. Evidence for top-down regulation was rare. Although nonindigenous dreissenid mussels probably have large impacts on nutrient cycling and phytoplankton, their effects on higher trophic levels remain uncertain. We highlight gaps for which monitoring and knowledge should improve the understanding of food-web dynamics and facilitate the implementation of ecosystem-based management.</span></p>","language":"English","publisher":"Oxford Academic","doi":"10.1093/biosci/bit001","usgsCitation":"Bunnell, D., Barbiero, R.P., Ludsin, S.A., Madenjian, C.P., Warren, G.J.,

The watershed model produced a discharge time series (hydrograph) in two study reaches under three climate scenarios: a baseline (1981–2005), a 1-°C increase in mean air temperature (plus one scenario), and a 2-°C increase (plus two scenario). A river operations model modified the discharge time series with Yakima River operational rules, a 2D model provided spatially explicit depth and velocity grids for two floodplain reaches, while an expert panel provided habitat criteria for four life stages of coho and fall Chinook salmon. We generated discharge-habitat functions for each salmonid life stage (e.g., spawning, rearing) in main stem and side channels, and habitat time series for baseline, plus one (P1) and plus two (P2) scenarios. The spatial and temporal patterns in salmonid habitats differed by reach, life stage, and climate scenario. Seventy-five percent of the 28 discharge-habitat responses exhibited a decrease in habitat quantity, with the P2 scenario producing the largest changes, followed by P1. Fry and spring/summer rearing habitats were the most sensitive to warming and flow modification for both species. Side channels generally produced more habitat than main stem and were more responsive to flow changes, demonstrating the importance of lateral connectivity in the floodplain. A discharge-habitat sensitivity analysis revealed that proactive management of regulated surface waters (i.e., increasing or decreasing flows) might lessen the impacts of climate change on salmonid habitats.","language":"English","publisher":"Springer","doi":"10.1007/s10584-013-0980-4","usgsCitation":"Hatten, J.R., Batt, T.R., Connolly, P., and Maule, A.G., 2014, Modeling effects of climate change on Yakima River salmonid habitats: Climatic Change, v. 124, no. 1-2, p. 427-439, https://doi.org/10.1007/s10584-013-0980-4.","productDescription":"13 p.","startPage":"427","endPage":"439","numberOfPages":"13","ipdsId":"IP-045665","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":473333,"rank":3,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s10584-013-0980-4","text":"Publisher Index Page"},{"id":280270,"rank":2,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280259,"rank":1,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10584-013-0980-4"}],"country":"United States","state":"Washington","otherGeospatial":"Yakima Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -121.5,45.75 ], [ -121.5,48.5 ], [ -119.25,48.5 ], [ -119.25,45.75 ], [ -121.5,45.75 ] ] ] } } ] }","volume":"124","issue":"1-2","noUsgsAuthors":false,"publicationDate":"2013-11-07","publicationStatus":"PW","scienceBaseUri":"52aadaf0e4b078ad3e40e3aa","contributors":{"authors":[{"text":"Hatten, James R. 0000-0003-4676-8093 jhatten@usgs.gov","orcid":"https://orcid.org/0000-0003-4676-8093","contributorId":3431,"corporation":false,"usgs":true,"family":"Hatten","given":"James","email":"jhatten@usgs.gov","middleInitial":"R.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":487285,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Batt, Thomas R. tbatt@usgs.gov","contributorId":3432,"corporation":false,"usgs":true,"family":"Batt","given":"Thomas","email":"tbatt@usgs.gov","middleInitial":"R.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":487286,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Connolly, Patrick J. 0000-0001-7365-7618 pconnolly@usgs.gov","orcid":"https://orcid.org/0000-0001-7365-7618","contributorId":2920,"corporation":false,"usgs":true,"family":"Connolly","given":"Patrick J.","email":"pconnolly@usgs.gov","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":487284,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Maule, Alec G. amaule@usgs.gov","contributorId":2606,"corporation":false,"usgs":true,"family":"Maule","given":"Alec","email":"amaule@usgs.gov","middleInitial":"G.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":487283,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Using remotely-sensed data, we developed procedures to measure breeding habitat abundance for the federally listed piping plover (Charadrius melodus) at Lake Sakakawea, North Dakota, USA. We also developed a model to predict habitat abundance based on past and projected water levels, vegetation colonization rates, and topography. Previous studies define plover habitat as flat areas (<10% slope) with ≤30% obstruction of bare substrate. Compared to ground-based data, remotely-sensed habitat classifications (≤30/>30% bare-substrate obstruction) were 76% correct and omission and commission errors were equal. Due to water level fluctuations, habitat abundance varied markedly among years (1986–2009) ranging from 9 to 5195 ha. The proportion bare substrate declined with the number of years since a contour was inundated until 5 years (&beta; = -0.65, SE = 0.05), then it stabilized near zero, and the decline varied by shoreline segment (5, 50, and 95 percentile were &beta; = -0.19, SE = 0.05, &beta; = -0.63, SE = 0.05, and &beta; = -0.91, SE = 0.05, respectively). Years since inundated predicted habitat abundance well at shoreline segments (R<sup>2</sup> = 0.77), but it predicted better for the whole lake (R<sup>2</sup> = 0.86). The vastness and dynamics of plover habitat on Lake Sakakawea suggest that this is a key area for conservation of this species. Model-based habitat predictions can benefit resource conservation because they can (1) form the basis for a sampling stratification, (2) help allocate monitoring efforts among areas, and (3) help inform management through simulations or what-if scenarios.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Modelling","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.ecolmodel.2013.08.020","usgsCitation":"Anteau, M.J., Wiltermuth, M.T., Sherfy, M.H., and Shaffer, T.L., 2014, Measuring and predicting abundance and dynamics of habitat for piping plovers on a large reservoir: Ecological Modelling, v. 272, p. 16-27, https://doi.org/10.1016/j.ecolmodel.2013.08.020.","productDescription":"12 p.","startPage":"16","endPage":"27","ipdsId":"IP-041452","costCenters":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":278655,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278654,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.ecolmodel.2013.08.020"}],"country":"United States","state":"North Dakota","otherGeospatial":"Lake Sakakawea","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -103.5771,47.4491 ], [ -103.5771,48.1718 ], [ -101.2537,48.1718 ], [ -101.2537,47.4491 ], [ -103.5771,47.4491 ] ] ] } } ] }","volume":"272","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5274c67ee4b089748f07132a","contributors":{"authors":[{"text":"Anteau, Michael J. 0000-0002-5173-5870 manteau@usgs.gov","orcid":"https://orcid.org/0000-0002-5173-5870","contributorId":3427,"corporation":false,"usgs":true,"family":"Anteau","given":"Michael","email":"manteau@usgs.gov","middleInitial":"J.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":485578,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wiltermuth, Mark T. 0000-0002-8871-2816 mwiltermuth@usgs.gov","orcid":"https://orcid.org/0000-0002-8871-2816","contributorId":708,"corporation":false,"usgs":true,"family":"Wiltermuth","given":"Mark","email":"mwiltermuth@usgs.gov","middleInitial":"T.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true},{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":true,"id":485576,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sherfy, Mark H. 0000-0003-3016-4105 msherfy@usgs.gov","orcid":"https://orcid.org/0000-0003-3016-4105","contributorId":125,"corporation":false,"usgs":true,"family":"Sherfy","given":"Mark","email":"msherfy@usgs.gov","middleInitial":"H.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":485575,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shaffer, Terry L. 0000-0001-6950-8951 tshaffer@usgs.gov","orcid":"https://orcid.org/0000-0001-6950-8951","contributorId":3192,"corporation":false,"usgs":true,"family":"Shaffer","given":"Terry","email":"tshaffer@usgs.gov","middleInitial":"L.","affiliations":[{"id":480,"text":"Northern Prairie Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":485577,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

In this study, we evaluate multi-year effects of implanted transmitters on migratory timing and reproductive performance in shorebirds. Shorebirds increasingly are recognized as good models in ecology and evolution. That many of them are of conservation concern adds to the research responsibilities. In May 2009, we captured 56 female Black-tailed Godwits <i>Limosa limosa limosa</i> during late incubation in The Netherlands. Of these, 15 birds were equipped with 26-g satellite transmitters with a percutaneous antenna (7.8 % ± 0.2 SD of body mass), surgically implanted in the coelom. We compared immediate nest survival, timing of migration, subsequent nest site fidelity and reproductive behaviour including egg laying with those of the remaining birds, a comparison group of 41 females. We found no effects on immediate nest survival. Fledging success and subsequent southward and northward migration patterns of the implanted birds conformed to the expectations, and arrival time on the breeding grounds in 2010–2012 did not differ from the comparison group. Compared with the comparison group, in the year after implantation, implanted birds were equally faithful to the nest site and showed equal territorial behaviour, but a paucity of behaviours indicating nests or clutches. In the 3 years after implantation, the yearly apparent survival of implanted birds was 16 % points lower. Despite intense searching, we found only three eggs of two implanted birds; all were deformed. A similarly deformed egg was reported in a similarly implanted Whimbrel <i>Numenius phaeopus</i> returning to breed in central Alaska. The presence in the body cavity of an object slightly smaller than a normal egg may thus lead to egg malformation and, likely, reduced egg viability. That the use of implanted satellite transmitters in these large shorebirds reduced nesting propensity and might also lead to fertility losses argues against the use of implanted transmitters for studies on breeding biology, and for a careful evaluation of the methodology in studies of migration.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Ornithology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s10336-013-1026-4","usgsCitation":"Hooijmeijer, J.C., Gill, R., Mulcahy, D.M., Tibbitts, T.L., Kentie, R., Gerritsen, G.J., Bruinzeel, L.W., Tijssen, D.C., Harwood, C.M., and Piersma, T., 2014, Abdominally implanted satellite transmitters affect reproduction and survival rather than migration of large shorebirds: Journal of Ornithology, v. 155, no. 2, p. 447-457, https://doi.org/10.1007/s10336-013-1026-4.","productDescription":"11 p.","startPage":"447","endPage":"457","numberOfPages":"11","ipdsId":"IP-039730","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":281819,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281818,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10336-013-1026-4"}],"country":"The Netherlands","state":"Friesl","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 5.387222,52.849722 ], [ 5.387222,53.044722 ], [ 5.421111,53.044722 ], [ 5.421111,52.849722 ], [ 5.387222,52.849722 ] ] ] } } ] }","volume":"155","issue":"2","noUsgsAuthors":false,"publicationDate":"2014-04-01","publicationStatus":"PW","scienceBaseUri":"537f1c5fe4b021317a86e2dd","contributors":{"authors":[{"text":"Hooijmeijer, Jos C.

We reviewed studies examining wildlife responses to MPB outbreaks and postoutbreak salvage logging to inform forest management and guide future research. Our review included 16 studies describing MPB outbreak relationships with 89 bird species and 6 studies describing relationships with 11 mammalian species, but no studies of reptiles or amphibians. We included studies that compared wildlife response metrics temporally (before versus after the outbreak) and spatially (across sites that varied in severity of outbreak) in relation to beetle outbreaks. Outbreaks ranged in size from 20,600 to ≥10<sup>7</sup> ha and studies occurred 1‐30 years after the peak MPB outbreak, but most studies were conducted over the short-term (i.e., ≤6 years after the peak of MPB-induced tree mortality). Birds were the only taxa studied frequently; however, high variability existed among those studies to allow many inferences, although some patterns were evident. Avian studies concluded that cavity-nesting species responded more favorably to beetle-killed forests than species with open-cup nests, and species nesting in the shrub layer favored outbreak forests compared with ground and open-cup canopy nesters that generally showed mixed relationships. Bark-drilling species as a group clearly demonstrated a positive short-term association with MPB epidemics compared with that of other foraging assemblages. Cavity-nesting birds that do not consume bark beetles (i.e., secondary cavity-nesting species and nonbark-drilling woodpeckers) also exhibited some positive responses to MPB outbreaks, although not as pronounced or consistent as those of bark-drilling woodpeckers. Mammalian responses to MPB outbreaks were mixed. Studies consistently reported negative effects of MPB outbreaks on red squirrels (<i>Tamiasciurus hudsonicus</i>). However, there is evidence that red squirrels can persist after an outbreak under some conditions, e.g., when nonhost tree species are present. For small mammal species associated with forest understories, responses may be most pronounced during the postepidemic period (&gt;6 years after the peak of beetle-induced tree mortality) when snags fall to produce coarse woody debris. Postoutbreak salvage logging studies (<i>n</i> = 6) reported results that lacked consensus. Postoutbreak salvage logging may have an impact on fewer wildlife species than postfire salvage logging, probably because only host-specific tree species are removed after beetle outbreaks.</p>","language":"English","publisher":"Society of American Foresters","doi":"10.5849/forsci.13-022","usgsCitation":"Saab, V.A., Latif, Q.S., Rowland, M., Johnson, T., Chalfoun, A., Buskirk, S.W., Heyward, J.E., and Dresser, M.A., 2014, Ecological consequences of mountain pine beetle outbreaks for wildlife in western North American forests: Forest Science, v. 60, no. 3, p. 539-559, https://doi.org/10.5849/forsci.13-022.","productDescription":"21 p.","startPage":"539","endPage":"559","numberOfPages":"21","ipdsId":"IP-051192","costCenters":[{"id":683,"text":"Wyoming Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":281068,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -139.06,37.0 ], [ -139.06,60.0 ], [ -96.44,60.0 ], [ -96.44,37.0 ], [ -139.06,37.0 ] ] ] } } ] }","volume":"60","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53ae7693e4b0abf75cf2bfa8","contributors":{"authors":[{"text":"Saab, Victoria A.","contributorId":82963,"corporation":false,"usgs":true,"family":"Saab","given":"Victoria","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":484761,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Latif, Quresh S.","contributorId":8382,"corporation":false,"usgs":true,"family":"Latif","given":"Quresh","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":484755,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rowland, Mary M.","contributorId":67411,"corporation":false,"usgs":true,"family":"Rowland","given":"Mary M.","affiliations":[],"preferred":false,"id":484760,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Johnson, Tracey N.","contributorId":97425,"corporation":false,"usgs":true,"family":"Johnson","given":"Tracey N.","affiliations":[],"preferred":false,"id":484762,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Chalfoun, Anna D.","contributorId":36794,"corporation":false,"usgs":true,"family":"Chalfoun","given":"Anna D.","affiliations":[],"preferred":false,"id":484758,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Buskirk, Steven W.","contributorId":13545,"corporation":false,"usgs":true,"family":"Buskirk","given":"Steven","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":484756,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Heyward, Joslin E.","contributorId":52888,"corporation":false,"usgs":true,"family":"Heyward","given":"Joslin","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":484759,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Dresser, Matthew A.","contributorId":29736,"corporation":false,"usgs":true,"family":"Dresser","given":"Matthew","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":484757,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Methods commonly used to extract PrPTSE from soils release substantial amounts of NOM, and NOM inhibited PrPTSE immunoblot signal. The degree of immunoblot interference increased with increasing NOM concentration and decreasing NOM polarity. Humic substances affected immunoblot detection of prion protein from both deer and hamsters. We also establish that after interaction with humic acid, PrP<sup>TSE</sup> remains infectious to hamsters inoculated intracerebrally, and humic acid appeared to slow disease progression. These results provide evidence for interactions between PrPTSE and humic substances that influence both accurate measurement of PrP<sup>TSE</sup> in soil and disease transmission.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Soil Biology and Biochemistry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.soilbio.2013.10.005","usgsCitation":"Smith, C.B., Booth, C.J., Wadzinski, T.J., Legname, G., Chappell, R., Johnson, C.J., and Pedersen, J.A., 2014, Humic substances interfere with detection of pathogenic prion protein: Soil Biology and Biochemistry, v. 68, p. 309-316, https://doi.org/10.1016/j.soilbio.2013.10.005.","productDescription":"8 p.","startPage":"309","endPage":"316","ipdsId":"IP-029446","costCenters":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"links":[{"id":278616,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278615,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.soilbio.2013.10.005"}],"volume":"68","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52736dfde4b097f32ac3dae3","contributors":{"authors":[{"text":"Smith, Christen B.","contributorId":105210,"corporation":false,"usgs":true,"family":"Smith","given":"Christen","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":485517,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Booth, Clarissa J.","contributorId":90626,"corporation":false,"usgs":true,"family":"Booth","given":"Clarissa","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":485515,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wadzinski, Tyler J.","contributorId":103169,"corporation":false,"usgs":true,"family":"Wadzinski","given":"Tyler","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":485516,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Legname, Giuseppe","contributorId":58546,"corporation":false,"usgs":true,"family":"Legname","given":"Giuseppe","email":"","affiliations":[],"preferred":false,"id":485512,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Chappell, Rick","contributorId":77034,"corporation":false,"usgs":true,"family":"Chappell","given":"Rick","email":"","affiliations":[],"preferred":false,"id":485513,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Johnson, Christopher J. cjjohnson@usgs.gov","contributorId":3491,"corporation":false,"usgs":true,"family":"Johnson","given":"Christopher","email":"cjjohnson@usgs.gov","middleInitial":"J.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":485511,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Pedersen, Joel A.","contributorId":85079,"corporation":false,"usgs":true,"family":"Pedersen","given":"Joel","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":485514,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

In reality, however, structural and nonstructural systems can have other damping ratios. This paper develops a new model for a damping scaling factor (DSF) that can be used to adjust the 5% damped spectral ordinates predicted by a GMPE for damping ratios between 0.5% to 30%. The model is developed based on empirical data from worldwide shallow crustal earthquakes in active tectonic regions. Dependencies of the DSF on potential predictor variables, such as the damping ratio, spectral period, ground motion duration, moment magnitude, source-to-site distance, and site conditions, are examined. The strong influence of duration is captured by the inclusion of both magnitude and distance in the DSF model. Site conditions show weak influence on the DSF. The proposed damping scaling model provides functional forms for the median and logarithmic standard deviation of DSF, and is developed for both RotD50 and GMRotI50 horizontal components. A follow-up paper develops a DSF model for vertical ground motion.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Earthquake Spectra","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Earthquake Engineering Research Institute","publisherLocation":"Berkeley, CA","doi":"10.1193/100512EQS298M","usgsCitation":"Rezaeian, S., Bozorgnia, Y., Idriss, I., Abrahamson, N., Campbell, K., and Silva, W., 2014, Damping scaling factors for elastic response spectra for shallow crustal earthquakes in active tectonic regions: \"average\" horizontal component: Earthquake Spectra, v. 30, no. 2, p. 939-963, https://doi.org/10.1193/100512EQS298M.","productDescription":"25 p.","startPage":"939","endPage":"963","numberOfPages":"25","ipdsId":"IP-048850","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":278559,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278556,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1193/100512EQS298M"}],"volume":"30","issue":"2","noUsgsAuthors":false,"publicationDate":"2014-05-01","publicationStatus":"PW","scienceBaseUri":"5270caf9e4b0f7a10664c764","contributors":{"authors":[{"text":"Rezaeian, Sanaz 0000-0001-7589-7893 srezaeian@usgs.gov","orcid":"https://orcid.org/0000-0001-7589-7893","contributorId":4395,"corporation":false,"usgs":true,"family":"Rezaeian","given":"Sanaz","email":"srezaeian@usgs.gov","affiliations":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":485396,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bozorgnia, Yousef","contributorId":40101,"corporation":false,"usgs":false,"family":"Bozorgnia","given":"Yousef","affiliations":[{"id":6643,"text":"University of California - Berkeley","active":true,"usgs":false}],"preferred":false,"id":485397,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Idriss, I.M.","contributorId":105412,"corporation":false,"usgs":true,"family":"Idriss","given":"I.M.","email":"","affiliations":[],"preferred":false,"id":485401,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Abrahamson, Norman","contributorId":66990,"corporation":false,"usgs":true,"family":"Abrahamson","given":"Norman","affiliations":[],"preferred":false,"id":485399,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Campbell, Kenneth","contributorId":86246,"corporation":false,"usgs":true,"family":"Campbell","given":"Kenneth","affiliations":[],"preferred":false,"id":485400,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Silva, Walter","contributorId":50429,"corporation":false,"usgs":true,"family":"Silva","given":"Walter","affiliations":[],"preferred":false,"id":485398,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Pixels from the Moderate Resolution Imaging Spectrometer (MODIS) sensors on the Terra satellite showed a sharp drop in NDVI in midsummer followed by recovery, correlated with defoliation events as revealed in networked digital camera images and ground surveys. Ground surveys and MODIS imagery showed that beetle damage progressed downstream at a rate of about 25 km yr<sup>−1</sup> in 2010 and 2011, producing a 50% reduction in saltcedar leaf area index and evapotranspiration by 2012, as estimated by algorithms based on MODIS Enhanced Vegetation Index values and local meteorological data for Mesquite, Nevada. This reduction is the equivalent of 10.4% of mean annual river flows on this river reach. Our results confirm other observations that saltcedar beetles are dispersing much faster than originally predicted in pre-release biological assessments, presenting new challenges and opportunities for land, water and wildlife managers on western rivers. Despite relatively coarse resolution (250 m) and gridding artifacts, single MODIS pixels can be useful in tracking the effects of defoliating insects in riparian corridors.","language":"English","publisher":"Elsevier","doi":"10.1016/j.rse.2013.08.017","usgsCitation":"Nagler, P.L., Pearlstein, S., Glenn, E.P., Brown, T.B., Bateman, H.L., Bean, D., and Hultine, K.R., 2014, Rapid dispersal of saltcedar (Tamarix spp.) biocontrol beetles (Diorhabda carinulata) on a desert river detected by phenocams, MODIS imagery and ground observations: Remote Sensing of Environment, v. 140, p. 206-219, https://doi.org/10.1016/j.rse.2013.08.017.","productDescription":"14 p.","startPage":"206","endPage":"219","numberOfPages":"14","ipdsId":"IP-044868","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":278471,"rank":2,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278470,"rank":1,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.rse.2013.08.017"}],"country":"United States","state":"Arizona, Nevada","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.350000,36.500000 ], [ -114.350000,37.000000 ], [ -113.991667,37.000000 ], [ -113.991667,36.500000 ], [ -114.350000,36.500000 ] ] ] } } ] }","volume":"140","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"526f7972e4b0493c992e9972","contributors":{"authors":[{"text":"Nagler, Pamela L. 0000-0003-0674-103X pnagler@usgs.gov","orcid":"https://orcid.org/0000-0003-0674-103X","contributorId":1398,"corporation":false,"usgs":true,"family":"Nagler","given":"Pamela","email":"pnagler@usgs.gov","middleInitial":"L.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":485286,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pearlstein, Susanna","contributorId":107577,"corporation":false,"usgs":true,"family":"Pearlstein","given":"Susanna","affiliations":[],"preferred":false,"id":485292,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Glenn, Edward P.","contributorId":19289,"corporation":false,"usgs":true,"family":"Glenn","given":"Edward","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":485287,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Brown, Tim B.","contributorId":57360,"corporation":false,"usgs":true,"family":"Brown","given":"Tim","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":485289,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Bateman, Heather L.","contributorId":72294,"corporation":false,"usgs":true,"family":"Bateman","given":"Heather","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":485291,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Bean, Dan W.","contributorId":58133,"corporation":false,"usgs":true,"family":"Bean","given":"Dan W.","affiliations":[],"preferred":false,"id":485290,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Hultine, Kevin R. 0000-0001-9747-6037","orcid":"https://orcid.org/0000-0001-9747-6037","contributorId":23772,"corporation":false,"usgs":true,"family":"Hultine","given":"Kevin","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":485288,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Protecting migratory species is complex because they cross international borders and depend on multiple regions. Understanding how much, and where, humans place value on migratory species can facilitate market‐based conservation approaches. We performed a contingent valuation study of monarchs to understand the potential for such approaches to fund monarch conservation. The survey asked U.S. respondents about the money they would spend, or have spent, growing monarch‐friendly plants, and the amount they would donate to monarch conservation organizations. Combining planting payments and donations, the survey indicated U.S. households valued monarchs as a total one‐time payment of \\$4.78–\\$6.64 billion, levels similar to many endangered vertebrate species. The financial contribution of even a small percentage of households through purchases or donations could generate new funding for monarch conservation through market‐based approaches.</span></p>","language":"English","publisher":"Society for Conservation Biology","doi":"10.1111/conl.12065","usgsCitation":"Diffendorfer, J., Loomiz, J., Ries, L., Oberhauser, K.,

We evaluated 4 capture techniques for bighorn sheep lambs: 1) hand-capture of lambs from radiocollared adult females fitted with vaginal implant transmitters (VITs), 2) hand-capture of lambs of intensively monitored radiocollared adult females, 3) helicopter net-gunning, and 4) hand-capture of lambs from helicopters. During 2010–2012, we successfully captured 90% of lambs from females that retained VITs to ≤1 day of parturition, although we noted differences in capture rates between an area of high road density in the Black Hills (92–100%) of South Dakota, USA, and less accessible areas of New Mexico (71%), USA. Retention of VITs was 78% with pre-partum expulsion the main cause of failure. We were less likely to capture lambs from females that expelled VITs ≥1 day of parturition (range = 80–83%) or females that were collared without VITs (range = 60–78%). We used helicopter net-gunning at several sites in 1999, 2001–2002, and 2011, and it proved a useful technique; however, at one site, attempts to capture lambs led to lamb predation by golden eagles (<i>Aquila chrysaetos</i>). We attempted helicopter hand-captures at one site in 1999, and they also were successful in certain circumstances and avoided risk of physical trauma from net-gunning; however, application was limited. In areas of low accessibility or if personnel lack the ability to monitor females and/or VITs for extended periods, helicopter capture may provide a viable option for lamb capture.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Wildlife Society Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"The Wildlife Society","doi":"10.1002/wsb.360","usgsCitation":"Smith, J.B., Walsh, D.P., Goldstein, E., Parsons, Z.D., Karsch, R., Stiver, J.R., Cain, J.W., Raedeke, K.J., and Jenks, J., 2014, Techniques for capturing bighorn sheep lambs: Wildlife Society Bulletin, v. 31, no. 1, p. 165-174, https://doi.org/10.1002/wsb.360.","productDescription":"10 p.","startPage":"165","endPage":"174","numberOfPages":"10","ipdsId":"IP-042867","costCenters":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true},{"id":471,"text":"New Mexico Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":500037,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://doaj.org/article/7aebda216b99449a8afec7eeda75612d","text":"External Repository"},{"id":280949,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280948,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/wsb.360"}],"country":"United States","state":"Colorado;New Mexico;South Dakota","otherGeospatial":"Black Hills;Pikes Peak;Peloncillo Mountains","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -109.03,31.2 ], [ -109.03,45.95 ], [ -102.0,45.95 ], [ -102.0,31.2 ], [ -109.03,31.2 ] ] ] } } ] }","volume":"31","issue":"1","noUsgsAuthors":false,"publicationDate":"2013-10-26","publicationStatus":"PW","scienceBaseUri":"53559598e4b0120853e8c241","contributors":{"authors":[{"text":"Smith, Joshua B.","contributorId":71883,"corporation":false,"usgs":true,"family":"Smith","given":"Joshua","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":477358,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Walsh, Daniel P. 0000-0002-7772-2445 dwalsh@usgs.gov","orcid":"https://orcid.org/0000-0002-7772-2445","contributorId":4758,"corporation":false,"usgs":true,"family":"Walsh","given":"Daniel","email":"dwalsh@usgs.gov","middleInitial":"P.","affiliations":[{"id":456,"text":"National Wildlife Health Center","active":true,"usgs":true}],"preferred":true,"id":477352,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Goldstein, Elise J.","contributorId":32825,"corporation":false,"usgs":true,"family":"Goldstein","given":"Elise J.","affiliations":[],"preferred":false,"id":477355,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Parsons, Zachary D.","contributorId":30143,"corporation":false,"usgs":true,"family":"Parsons","given":"Zachary","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":477354,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Karsch, Rebekah C.","contributorId":64159,"corporation":false,"usgs":true,"family":"Karsch","given":"Rebekah C.","affiliations":[],"preferred":false,"id":477357,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Stiver, Julie R.","contributorId":78244,"corporation":false,"usgs":true,"family":"Stiver","given":"Julie","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":477359,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Cain, James W.

Our understanding of competition's importance at broader scales is less resolved and mainly based on static species distribution maps. Here, we bridge this gap by examining the joint occupancy dynamics of an invading (barred owl: Strix varia) and a resident species (Northern spotted owl: Strix occidentalis caurina) in a 1000 km2 study area over a 22 - year period. Past studies of these competitors have focused on the dynamics of one species at a time, hindering efforts to parse out the roles of habitat and competition and to forecast the future of the resident species. In addition, while these studies accounted for the imperfect detection of the focal species, no multiseason analysis of these species has accounted for the imperfect detection of the secondary species, potentially biasing inference. We analyze survey data using models that combine the general multistate-multiseason occupancy modeling framework with autologistic modeling - allowing us to account for important aspects of our study system.</p>\n<br/>\n<p>We find that local extinction probability increases for each species when the other is present; however, the effect of the invader on the resident is greater. Although the species prefer different habitats, these habitats are highly correlated at the patch scale and the impacts of invader on the resident are greatest in patches that would otherwise be optimal. As a consequence, competition leads to a weaker relationship between habitat and Northern spotted owl occupancy. Colonization and extinction rates of the invader are closely related to neighborhood occupancy, and over the first half of the study the availability of colonists limited the rate of population growth. Competition is likely to exclude the resident species both through its immediate effects on local extinction, and by indirectly lowering colonization rates as Northern spotted owl occupancy declines. Our analysis suggests that dispersal limitation affects both the invasion dynamics and the scale at which the effects of competition are observed. We also provide predictions regarding the potential costs and benefits of managing barred owl populations at different target levels.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ecological Society of America","doi":"10.1890/13-0012.1","usgsCitation":"Yackulic, C.B., Reid, J., Nichols, J., Hines, J., Davis, R., and Forsman, E., 2014, The roles of competition and habitat in the dynamics of populations and species distributions: Ecology, v. 95, no. 2, p. 265-279, https://doi.org/10.1890/13-0012.1.","productDescription":"15 p.","startPage":"265","endPage":"279","numberOfPages":"15","ipdsId":"IP-051859","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":278343,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278342,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/13-0012.1"}],"country":"United States","state":"Oregon","volume":"95","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5268e1cfe4b0584cbe916841","contributors":{"authors":[{"text":"Yackulic, Charles Brandon","contributorId":63300,"corporation":false,"usgs":true,"family":"Yackulic","given":"Charles","email":"","middleInitial":"Brandon","affiliations":[],"preferred":false,"id":485074,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reid, Janice","contributorId":89391,"corporation":false,"usgs":false,"family":"Reid","given":"Janice","affiliations":[{"id":6644,"text":"Princeton University","active":true,"usgs":false}],"preferred":false,"id":485075,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"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":485071,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hines, James E. jhines@usgs.gov","contributorId":3506,"corporation":false,"usgs":true,"family":"Hines","given":"James E.","email":"jhines@usgs.gov","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":false,"id":485072,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Davis, Raymond","contributorId":91349,"corporation":false,"usgs":true,"family":"Davis","given":"Raymond","affiliations":[],"preferred":false,"id":485076,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Forsman, Eric","contributorId":28470,"corporation":false,"usgs":true,"family":"Forsman","given":"Eric","affiliations":[],"preferred":false,"id":485073,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Analysis of more than 440 000 quality-filtered sequences obtained from the foregut and hindgut of GZSD and SVCP revealed high microbial diversity in these samples. GZSD hindgut (GZSD_H) samples (n=23) with >7000 operational taxonomy units (OTUs) exhibited the highest alpha-diversity indices followed by SVCP foregut (n=15), GZSD foregut (n=9) and SVCP hindgut (SVCP_H) (n=24). UniFrac distance-based non-metric multidimensional scaling (NMDS) analysis showed that the microbiota of GZSD_H and SVCP_H were clearly separated into two clusters: samples in the GZSD cluster were observed to vary by sampling location and samples in the SVCP cluster by sampling date. NMDS further revealed distinct microbial community between foregut to hindgut for individual GZSD and SVCP. Cyanobacteria, Proteobacteria, Actinobacteria and Bacteroidetes were detected as the predominant phyla regardless of fish or gut type. The high abundance of Cyanobacteria observed was possibly supported by their role as the fish’s major food source. Furthermore, unique and shared OTUs and OTUs in each gut type were identified, three OTUs from the order Bacteroidales, the genus Bacillariophyta and the genus Clostridium were found significantly more abundant in GZSD_H (14.9–22.8%) than in SVCP_H (0.13–4.1%) samples. These differences were presumably caused by the differences in the type of food sources including bacteria ingested, the gut morphology and digestion, and the physiological behavior between GZSD and SVCP.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"International Society for Microbial Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Nature Publishing Group","doi":"10.1038/ismej.2013.181","usgsCitation":"Ye, L., Amberg, J., Chapman, D., Gaikowski, M.P., and Liu, W., 2014, Fish gut microbiota analysis differentiates physiology and behavior of invasive Asian carp and indigenous American fish: International Society for Microbial Ecology, v. 8, p. 541-551, https://doi.org/10.1038/ismej.2013.181.","productDescription":"11 p.","startPage":"541","endPage":"551","numberOfPages":"11","ipdsId":"IP-045121","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":473337,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1038/ismej.2013.181","text":"Publisher Index Page"},{"id":278325,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278323,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1038/ismej.2013.181"}],"volume":"8","noUsgsAuthors":false,"publicationDate":"2013-10-17","publicationStatus":"PW","scienceBaseUri":"52679065e4b0c24c90856d7e","contributors":{"authors":[{"text":"Ye, Lin","contributorId":70682,"corporation":false,"usgs":true,"family":"Ye","given":"Lin","email":"","affiliations":[],"preferred":false,"id":484971,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Amberg, Jon J. jamberg@usgs.gov","contributorId":797,"corporation":false,"usgs":true,"family":"Amberg","given":"Jon J.","email":"jamberg@usgs.gov","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":false,"id":484969,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Chapman, Duane 0000-0002-1086-8853 dchapman@usgs.gov","orcid":"https://orcid.org/0000-0002-1086-8853","contributorId":1291,"corporation":false,"usgs":true,"family":"Chapman","given":"Duane","email":"dchapman@usgs.gov","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true},{"id":192,"text":"Columbia Environmental Research Center","active":true,"usgs":true}],"preferred":true,"id":484970,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gaikowski, Mark P. 0000-0002-6507-9341 mgaikowski@usgs.gov","orcid":"https://orcid.org/0000-0002-6507-9341","contributorId":796,"corporation":false,"usgs":true,"family":"Gaikowski","given":"Mark","email":"mgaikowski@usgs.gov","middleInitial":"P.","affiliations":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"preferred":false,"id":484968,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Liu, Wen-Tso","contributorId":71873,"corporation":false,"usgs":true,"family":"Liu","given":"Wen-Tso","email":"","affiliations":[],"preferred":false,"id":484972,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

European mouflon sheep (Ovis gmelini musimon) from the Mediterranean Islands were introduced to the Hawaiian Islands for sport hunting beginning in 1954 and were subsequently hybridized with feral domestic sheep (O. aries), which had been introduced in 1793. Three isolated mouflon populations have become established in the Hawaiian Islands but diseases in these populations have been little studied. The objective of this study was to evaluate and compare gross and histologic lesions in respiratory, renal, and hepatic systems of free-ranging sheep in two isolated volcanic environments on Hawai&lsquo;i Island. Tissue and fecal samples were collected in conjunction with population reductions during February 2011. We found gross or histologic evidence of lungworm infection in 44/49 sheep from Mauna Loa which were exposed to gaseous emissions from Kīlauea Volcano. In contrast, only 7/50 sheep from Mauna Kea had lesions consistent with lungworm, but Mauna Kea sheep had significantly more upper respiratory tract inflammation and hyperplasia consistent with chronic antigenic stimulation, possibly associated with exposure to fine airborne particulates during extended drought conditions. We hypothesize that gasses from Kīlauea Volcano contributed to severity of respiratory disease principally associated with chronic lungworm infections at Mauna Loa; however, there were numerous other potentially confounding environmental factors and interactions that merit further investigation.</p>","language":"English","publisher":"Pacific Science Association","doi":"10.2984/68.1.6","usgsCitation":"Powers, J.G., Duncan, C.G., Spraker, T.R., Schuler, B.A., Hess, S., Faford, J.K., and Sin, H., 2014, Environmental conditions associated with lesions in introduced free-ranging sheep in Hawai‘i: Pacific Science, v. 68, no. 1, p. 65-74, https://doi.org/10.2984/68.1.6.","productDescription":"10 p.","startPage":"65","endPage":"74","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-045728","costCenters":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"links":[{"id":278403,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawai'i","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -156.062,18.9108 ], [ -156.062,20.2686 ], [ -154.8065,20.2686 ], [ -154.8065,18.9108 ], [ -156.062,18.9108 ] ] ] } } ] }","volume":"68","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"526b9300e4b058918d0acb9f","contributors":{"authors":[{"text":"Powers, Jenny G.","contributorId":10710,"corporation":false,"usgs":true,"family":"Powers","given":"Jenny","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":485172,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Duncan, Colleen G.","contributorId":15512,"corporation":false,"usgs":false,"family":"Duncan","given":"Colleen","email":"","middleInitial":"G.","affiliations":[{"id":6621,"text":"Colorado State University","active":true,"usgs":false}],"preferred":false,"id":485173,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Spraker, Terry R.","contributorId":86676,"corporation":false,"usgs":true,"family":"Spraker","given":"Terry","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":485177,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Schuler, Bridget A.","contributorId":89051,"corporation":false,"usgs":true,"family":"Schuler","given":"Bridget","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":485178,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hess, Steven C.","contributorId":74462,"corporation":false,"usgs":true,"family":"Hess","given":"Steven C.","affiliations":[],"preferred":false,"id":485176,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Faford, Jonathan K.J.","contributorId":16739,"corporation":false,"usgs":true,"family":"Faford","given":"Jonathan","email":"","middleInitial":"K.J.","affiliations":[],"preferred":false,"id":485174,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Sin, Hans","contributorId":49265,"corporation":false,"usgs":true,"family":"Sin","given":"Hans","email":"","affiliations":[],"preferred":false,"id":485175,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

A recent increase in solar energy systems, especially large, centralized installations, underscores the urgency of understanding their environmental interactions. Synthesizing literature across numerous disciplines, we review direct and indirect environmental impacts – both beneficial and adverse – of utility-scale solar energy (USSE) development, including impacts on biodiversity, land-use and land-cover change, soils, water resources, and human health. Additionally, we review feedbacks between USSE infrastructure and land-atmosphere interactions and the potential for USSE systems to mitigate climate change. Several characteristics and development strategies of USSE systems have low environmental impacts relative to other energy systems, including other renewables. We show opportunities to increase USSE environmental co-benefits, the permitting and regulatory constraints and opportunities of USSE, and highlight future research directions to better understand the nexus between USSE and the environment. Increasing the environmental compatibility of USSE systems will maximize the efficacy of this key renewable energy source in mitigating climatic and global environmental change.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Renewable and Sustainable Energy Reviews","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.rser.2013.08.041","usgsCitation":"Hernandez, R., Easter, S., Murphy-Mariscal, M.L., Maestre, F., Tavassoli, M., Allen, E., Barrows, C., Belnap, J., Ochoa-Hueso, R., Ravi, S., and Allen, M., 2014, Environmental impacts of utility-scale solar energy: Renewable and Sustainable Energy Reviews, v. 29, p. 766-779, https://doi.org/10.1016/j.rser.2013.08.041.","productDescription":"14 p.","startPage":"766","endPage":"779","ipdsId":"IP-049628","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":473338,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://escholarship.org/uc/item/62w112cg","text":"External Repository"},{"id":278277,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":278235,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.rser.2013.08.041"}],"volume":"29","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"52624a67e4b079a99629a0df","contributors":{"authors":[{"text":"Hernandez, R.R.","contributorId":38464,"corporation":false,"usgs":true,"family":"Hernandez","given":"R.R.","email":"","affiliations":[],"preferred":false,"id":484842,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Easter, S.B.","contributorId":41731,"corporation":false,"usgs":true,"family":"Easter","given":"S.B.","email":"","affiliations":[],"preferred":false,"id":484843,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Murphy-Mariscal, M.

We examined net ecosystem production (NEP) for the temperate grasslands in northern China from 2000 to 2010. We combined flux observations, satellite data, and climate data to develop a piecewise regression model for NEP, and then used the model to map NEP for grasslands in northern China. Over the growing season, the northern China's grassland had a net carbon uptake of 158 ± 25 g C m<sup>−2</sup> during 2000–2010 with the mean regional NEP estimate of 126 Tg C. Our results showed generally higher grassland NEP at high latitudes (northeast) than at low latitudes (central and west) because of different grassland types and environmental conditions. In the northeast, which is dominated by meadow steppes, the growing season NEP generally reached 200–300 g C m<sup>−2</sup>. In the southwest corner of the region, which is partially occupied by alpine meadow systems, the growing season NEP also reached 200–300 g C m<sup>−2</sup>. In the central part, which is dominated by typical steppe systems, the growing season NEP generally varied in the range of 100–200 g C m−2. The NEP of the northern China's grasslands was highly variable through years, ranging from 129 (2001) to 217 g C m<sup>−2</sup> growing season<sup>−1</sup> (2010). The large interannual variations of NEP could be attributed to the sensitivity of temperate grasslands to climate changes and extreme climatic events. The droughts in 2000, 2001, and 2006 reduced the carbon uptake over the growing season by 11%, 29%, and 16% relative to the long-term (2000–2010) mean. Over the study period (2000–2010), precipitation was significantly correlated with NEP for the growing season (R<sup>2</sup> = 0.35, p-value < 0.1), indicating that water availability is an important stressor for the productivity of the temperate grasslands in semi-arid and arid regions in northern China. We conclude that northern temperate grasslands have the potential to sequester carbon, but the capacity of carbon sequestration depends on grassland types and environmental conditions. Extreme climate events like drought can significantly reduce the net carbon uptake of grasslands.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Agricultural and Forest
