Agricultural inputs from fertilizer and manure were the largest nutrient sources throughout a large part of the basin, although atmospheric and urban inputs were important sources in some areas. Sediment mobilized from stream channels was a source of phosphorus in medium and larger streams. Irrigation on agricultural land was estimated to decrease the nitrogen load reaching the Mississippi River by as much as 17%, likely as a result of increased anoxia and denitrification in the soil zone. Approximately 16% of the nitrogen load and 33% of the phosphorus load that would have otherwise reached the Mississippi River was retained in reservoirs and lakes throughout the basin. Nearly half of the total attenuation occurred in the eight largest water bodies. Unlike the other major tributary basins, nearly the entire instream nutrient load leaving the outlet of the Platte and Kansas River subbasins reached the Mississippi River. Most of the larger reservoirs and lakes in the Platte River subbasin are upstream of the major sources, whereas in the Kansas River subbasin, most of the source inputs are in the southeast part of the subbasin where characteristics of the area and proximity to the Missouri River facilitate delivery of nutrients to the Mississippi River.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the American Water Resources Association","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1111/j.1752-1688.2011.00584.x","issn":"1093474X","usgsCitation":"Brown, J., Sprague, L., and Dupree, J., 2011, Nutrient sources and transport in the Missouri River Basin, with emphasis on the effects of irrigation and reservoirs: Journal of the American Water Resources Association, v. 47, no. 5, p. 1034-1060, https://doi.org/10.1111/j.1752-1688.2011.00584.x.","productDescription":"27 p.","startPage":"1034","endPage":"1060","costCenters":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"links":[{"id":475402,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/3307633","text":"External Repository"},{"id":215775,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1752-1688.2011.00584.x"},{"id":243600,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States;Canada","otherGeospatial":"Missouri River Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.05,36.0 ], [ -116.05,50.0 ], [ -89.1,50.0 ], [ -89.1,36.0 ], [ -116.05,36.0 ] ] ] } } ] }","volume":"47","issue":"5","noUsgsAuthors":false,"publicationDate":"2011-08-22","publicationStatus":"PW","scienceBaseUri":"505a6941e4b0c8380cd73c27","contributors":{"authors":[{"text":"Brown, J.B.","contributorId":91307,"corporation":false,"usgs":true,"family":"Brown","given":"J.B.","email":"","affiliations":[],"preferred":false,"id":446466,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sprague, L.A.","contributorId":101712,"corporation":false,"usgs":true,"family":"Sprague","given":"L.A.","email":"","affiliations":[],"preferred":false,"id":446467,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dupree, J.A.","contributorId":29236,"corporation":false,"usgs":true,"family":"Dupree","given":"J.A.","email":"","affiliations":[],"preferred":false,"id":446465,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We sampled both the ecological and distributional limits of the foothill yellow-legged frog, Rana boylii to characterize mitochondrial DNA (mtDNA) variation in this declining, riverine amphibian. We evaluated 1525 base pairs (bp) of cytochrome b and ND2 fragments for 77 individuals from 34 localities using phylogenetic and population genetic analyses. We constructed gene trees using maximum likelihood and Bayesian inference, and quantified genetic variance (using AMOVA and partial Mantel tests) within and among hydrologic regions and river basins. Several moderately supported, geographically-cohesive mtDNA clades were recovered for R. boylii. While genetic variation was low among populations in the largest, most inclusive clade, samples from localities at the edges of the geographic range demonstrated substantial genetic divergence from each other and from more central populations. Hydrologic regions and river basins, which represent likely dispersal corridors for R. boylii, accounted for significant levels of genetic variation. These results suggest that both rivers and larger hydrologic and geographic regions should be used in conservation planning for R. boylii. ?? 2010 US Government.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Conservation Genetics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1007/s10592-010-0138-0","issn":"15660621","usgsCitation":"Lind, A., Spinks, P., Fellers, G.M., and Shaffer, H., 2011, Rangewide phylogeography and landscape genetics of the Western U.S. endemic frog Rana boylii (Ranidae): Implications for the conservation of frogs and rivers: Conservation Genetics, v. 12, no. 1, p. 269-284, https://doi.org/10.1007/s10592-010-0138-0.","startPage":"269","endPage":"284","numberOfPages":"16","costCenters":[],"links":[{"id":214509,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10592-010-0138-0"},{"id":242243,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","issue":"1","noUsgsAuthors":false,"publicationDate":"2010-10-09","publicationStatus":"PW","scienceBaseUri":"505a94aae4b0c8380cd81546","contributors":{"authors":[{"text":"Lind, A.J.","contributorId":46763,"corporation":false,"usgs":true,"family":"Lind","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":443325,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Spinks, P.Q.","contributorId":13454,"corporation":false,"usgs":true,"family":"Spinks","given":"P.Q.","email":"","affiliations":[],"preferred":false,"id":443323,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fellers, G.

To document the effects of the dams prior to their removal, we measured carbon and nitrogen stable isotope ratios of primary producers, benthic macroinvertebrates, and fish, and water chemistry above, between and below the dams. We found that δ<sup>15</sup>N was significantly higher in fish, stoneflies, black flies, periphyton and macroalgae where salmon still have access. Fish and chloroperlid stoneflies were enriched in δ<sup>13</sup>C, but the values were more variable than in δ<sup>15</sup>N. For some taxa, there were also differences between the two river sections that lack salmon, suggesting that factors other than marine-derived nutrients are structuring longitudinal isotopic profiles. Consistent with trophic theory, macroalgae had the lowest δ<sup>15</sup>N, followed by periphyton, macroinvertebrates and fish, with a range of 6.9, 6.2 and 7.7‰ below, between, and above the dams, respectively.

In geese, recruitment is strongly affected by habitat conditions experienced by broods because gosling growth rates are indicative of forage conditions during brood rearing and strongly influence future survival and productivity. In 2006–2008, we studied gosling growth at 3 of the 4 major colonies on the Yukon‐Kuskokwim Delta, Alaska. Estimates of age‐adjusted gosling mass at the 2 southern colonies (approx. 30% of the world population of breeding black brant) was low (gosling mass at 30.5 days ranged 346.7 ± 42.5 g to 627.1 ± 15.9 g) in comparison to a third colony (gosling mass at 30.5 days ranged 640.0 ± 8.3 g to 821.6 ± 13.6 g) and to most previous estimates of age‐adjusted mass of brant goslings. Thus, our results are consistent with the hypothesis that poor gosling growth is negatively influencing the brant population. There are 2 non‐mutually exclusive explanations for the apparent growth rates we observed. First, the population decline may have been caused by density‐independent factors and habitat capacity has declined along with the population as a consequence of the unique foraging feedback between brant and their grazing habitats. Alternatively, a reduction in habitat capacity, as a result of changes to the grazing system, may have negatively influenced gosling growth, which is contributing to the overall long‐term population decline. We found support for both explanations. For colonies over habitat capacity we recommend management to enhance foraging habitat, whereas for colonies below habitat capacity we recommend management to increase nesting productivity.</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/jwmg.24","issn":"0022541X","usgsCitation":"Fondell, T., Flint, P.L., Sedinger, J., Nicolai, C., and Schamber, J., 2011, Intercolony variation in growth of black brant goslings on the Yukon-Kuskokwim Delta, Alaska: Journal of Wildlife Management, v. 75, no. 1, p. 101-108, https://doi.org/10.1002/jwmg.24.","productDescription":"8 p.","startPage":"101","endPage":"108","numberOfPages":"8","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":244384,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216507,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/jwmg.24"}],"volume":"75","issue":"1","noUsgsAuthors":false,"publicationDate":"2011-01-31","publicationStatus":"PW","scienceBaseUri":"505a3cf0e4b0c8380cd63182","contributors":{"authors":[{"text":"Fondell, T.F.","contributorId":11154,"corporation":false,"usgs":true,"family":"Fondell","given":"T.F.","email":"","affiliations":[],"preferred":false,"id":443630,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Flint, Paul L. 0000-0002-8758-6993 pflint@usgs.gov","orcid":"https://orcid.org/0000-0002-8758-6993","contributorId":3284,"corporation":false,"usgs":true,"family":"Flint","given":"Paul","email":"pflint@usgs.gov","middleInitial":"L.","affiliations":[{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true},{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"preferred":true,"id":443632,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sedinger, J.S.","contributorId":75471,"corporation":false,"usgs":true,"family":"Sedinger","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":443633,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Nicolai, C.A.","contributorId":17420,"corporation":false,"usgs":true,"family":"Nicolai","given":"C.A.","email":"","affiliations":[],"preferred":false,"id":443631,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Schamber, J.L.","contributorId":92012,"corporation":false,"usgs":true,"family":"Schamber","given":"J.L.","email":"","affiliations":[],"preferred":false,"id":443634,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Pseudostatic analysis was the earliest method; it involved simply adding a permanent body force representing the earthquake shaking to a static limit-equilibrium analysis. Stress-deformation analysis, a later development, involved much more complex modeling of slopes using a mesh in which the internal stresses and strains within elements are computed based on the applied external loads, including gravity and seismic loads. Stress-deformation analysis provided the most realistic model of slope behavior, but it is very complex and requires a high density of high-quality soil-property data as well as an accurate model of soil behavior. In 1965, Newmark developed a method that effectively bridges the gap between these two types of analysis. His sliding-block model is easy to apply and provides a useful index of co-seismic slope performance. Subsequent modifications to sliding-block analysis have made it applicable to a wider range of landslide types. Sliding-block analysis provides perhaps the greatest utility of all the types of analysis. It is far easier to apply than stress-deformation analysis, and it yields much more useful information than does pseudostatic analysis.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.enggeo.2010.09.017","issn":"00137952","usgsCitation":"Jibson, R., 2011, Methods for assessing the stability of slopes during earthquakes-A retrospective: Engineering Geology, v. 122, no. 1-2, p. 43-50, https://doi.org/10.1016/j.enggeo.2010.09.017.","productDescription":"8 p.","startPage":"43","endPage":"50","costCenters":[],"links":[{"id":243374,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215562,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.enggeo.2010.09.017"}],"volume":"122","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a55a0e4b0c8380cd6d24c","contributors":{"authors":[{"text":"Jibson, R.W.","contributorId":8467,"corporation":false,"usgs":true,"family":"Jibson","given":"R.W.","email":"","affiliations":[],"preferred":false,"id":446542,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Of these, fishing is one of the most pervasive, and a growing body of work suggests that fishing can have strong effects on the ecology of target species, especially top predators. However, the effects of removing top predators on lower trophic groups of prey fishes are less clear, particularly in highly diverse and trophically complex coral reef ecosystems. We examined patterns of abundance, size structure, and age-based demography through surveys and collection-based studies of five fish species from a variety of trophic levels at Kiritimati and Palmyra, two nearby atolls in the Northern Line Islands. These islands have similar biogeography and oceanography, and yet Kiritimati has ∼10,000 people with extensive local fishing while Palmyra is a US National Wildlife Refuge with no permanent human population, no fishing, and an intact predator fauna. Surveys indicated that top predators were relatively larger and more abundant at unfished Palmyra, while prey functional groups were relatively smaller but showed no clear trends in abundance as would be expected from classic trophic cascades. Through detailed analyses of focal species, we found that size and longevity of a top predator were lower at fished Kiritimati than at unfished Palmyra. Demographic patterns also shifted dramatically for 4 of 5 fish species in lower trophic groups, opposite in direction to the top predator, including decreases in average size and longevity at Palmyra relative to Kiritimati. Overall, these results suggest that fishing may alter community structure in complex and non-intuitive ways, and that indirect demographic effects should be considered more broadly in ecosystem-based management.</span></p>","largerWorkTitle":"PLoS ONE","language":"English","publisher":"PLoS","doi":"10.1371/journal.pone.0021062","issn":"19326203","usgsCitation":"Ruttenberg, B., Hamilton, S., Walsh, S., Donovan, M., Friedlander, A.M., DeMartini, E., Sala, E., and Sandin, S., 2011, Predator-induced demographic shifts in coral reef fish assemblages: PLoS ONE, v. 6, no. 6, e21062, 9 p., https://doi.org/10.1371/journal.pone.0021062.","productDescription":"e21062, 9 p.","costCenters":[],"links":[{"id":475430,"rank":10000,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0021062","text":"Publisher Index Page"},{"id":246304,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218305,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1371/journal.pone.0021062"}],"otherGeospatial":"Northern Line Islands","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -162.158203125,\n              5.178482088522876\n            ],\n            [\n              -152.666015625,\n              5.178482088522876\n            ],\n            [\n              -152.666015625,\n              8.059229627200192\n            ],\n            [\n              -162.158203125,\n              8.059229627200192\n            ],\n            [\n              -162.158203125,\n              5.178482088522876\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"6","issue":"6","noUsgsAuthors":false,"publicationDate":"2011-06-16","publicationStatus":"PW","scienceBaseUri":"505a8175e4b0c8380cd7b53c","contributors":{"authors":[{"text":"Ruttenberg, B.I.","contributorId":21804,"corporation":false,"usgs":true,"family":"Ruttenberg","given":"B.I.","email":"","affiliations":[],"preferred":false,"id":454792,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hamilton, S.L.","contributorId":107546,"corporation":false,"usgs":true,"family":"Hamilton","given":"S.L.","email":"","affiliations":[],"preferred":false,"id":454797,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Walsh, S.M.","contributorId":89387,"corporation":false,"usgs":true,"family":"Walsh","given":"S.M.","email":"","affiliations":[],"preferred":false,"id":454796,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Donovan, Mary 0000-0001-6855-0197","orcid":"https://orcid.org/0000-0001-6855-0197","contributorId":229696,"corporation":false,"usgs":false,"family":"Donovan","given":"Mary","email":"","affiliations":[{"id":35760,"text":"University of Hawai'i","active":true,"usgs":false}],"preferred":false,"id":454794,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Friedlander, Alan M. afriedlander@usgs.gov","contributorId":4296,"corporation":false,"usgs":true,"family":"Friedlander","given":"Alan","email":"afriedlander@usgs.gov","middleInitial":"M.","affiliations":[],"preferred":false,"id":454790,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"DeMartini, E.","contributorId":54053,"corporation":false,"usgs":true,"family":"DeMartini","given":"E.","email":"","affiliations":[],"preferred":false,"id":454793,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Sala, E.","contributorId":74615,"corporation":false,"usgs":true,"family":"Sala","given":"E.","email":"","affiliations":[],"preferred":false,"id":454795,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Sandin, S.A.","contributorId":13078,"corporation":false,"usgs":true,"family":"Sandin","given":"S.A.","email":"","affiliations":[],"preferred":false,"id":454791,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

Linear regressions established that responses (intercepts and slopes) to urbanization of invertebrates and algae varied among metropolitan areas. Multilevel hierarchical regression models were able to explain these differences on the basis of region-scale predictors. Regional differences in the type of land cover (agriculture or forest) being converted to urban and climatic factors (precipitation and air temperature) accounted for the differences in the response of macroinvertebrates to urbanization based on ordination scores, total richness, Ephemeroptera, Plecoptera, Trichoptera richness, and average tolerance. Regional differences in climate and antecedent agriculture also accounted for differences in the responses of salt-tolerant diatoms, but differences in the responses of other diatom metrics (% eutraphenic, % sensitive, and % silt tolerant) were best explained by regional differences in soils (mean % clay soils). The effects of urbanization were most readily detected in regions where forest lands were being converted to urban land because agricultural development significantly degraded assemblages before urbanization and made detection of urban effects difficult. The effects of climatic factors (temperature, precipitation) on background conditions (biogeographic differences) and rates of response to urbanization were most apparent after accounting for the effects of agricultural development.

Given the strong role that wood plays in streams, factors that influence wood inputs, retention and transport are critical to stream ecology. Wood entrapment, the process of wood coming to rest after being swept downstream at least 10 m, is poorly understood, yet important for predicting stream function and success of restoration efforts. Data on entrapment were collected for a wide range of natural wood pieces (</span><i>n</i><span><span>&nbsp;</span>= 344), stream geomorphology and hydraulic conditions in nine streams along the north shore of Lake Superior in Minnesota. Locations of pieces were determined in summer 2007 and again following an overbank stormflow event in fall 2007. The ratio of piece length to effective stream width (length ratio) and the weight of the piece were important in a multiple logistic regression model that explained 25% of the variance in wood entrapment. Entrapment remains difficult to predict in natural streams, and often may simply occur wherever wood pieces are located when high water recedes. However, this study can inform stream modifications to discourage entrapment at road crossings or other infrastructure by applying the model formula to estimate the effective width required to pass particular wood pieces. Conversely, these results could also be used to determine conditions (e.g. pre-existing large, stable pieces) that encourage entrapment where wood is valued for ecological functions.</span></p>","language":"English","publisher":"Wiley","doi":"10.1002/hyp.7846","issn":"08856087","usgsCitation":"Merten, E.C., Finlay, J., Johnson, L., Newman, R., Stefan, H., and Vondracek, B.C., 2011, Environmental controls of wood entrapment in upper Midwestern streams: Hydrological Processes, v. 25, no. 4, p. 593-602, https://doi.org/10.1002/hyp.7846.","productDescription":"10 p.","startPage":"593","endPage":"602","numberOfPages":"10","ipdsId":"IP-018202","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":475242,"rank":10000,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/11299/183601","text":"External Repository"},{"id":244174,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216311,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/hyp.7846"}],"country":"United States","state":"Minnesota","otherGeospatial":"Lake Superior","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -92.2247314453125,\n              46.66828707388311\n            ],\n            [\n              -89.4451904296875,\n              46.66828707388311\n            ],\n            [\n              -89.4451904296875,\n              48.0156497866894\n            ],\n            [\n              -92.2247314453125,\n              48.0156497866894\n            ],\n            [\n              -92.2247314453125,\n              46.66828707388311\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"25","issue":"4","noUsgsAuthors":false,"publicationDate":"2010-09-07","publicationStatus":"PW","scienceBaseUri":"505a09b5e4b0c8380cd5201c","contributors":{"authors":[{"text":"Merten, Eric C.","contributorId":75355,"corporation":false,"usgs":false,"family":"Merten","given":"Eric","email":"","middleInitial":"C.","affiliations":[{"id":12644,"text":"University of Minnesota, St. Paul","active":true,"usgs":false}],"preferred":false,"id":451805,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Finlay, Jacques","contributorId":172286,"corporation":false,"usgs":false,"family":"Finlay","given":"Jacques","affiliations":[],"preferred":false,"id":451803,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Johnson, Lucinda","contributorId":172287,"corporation":false,"usgs":false,"family":"Johnson","given":"Lucinda","affiliations":[],"preferred":false,"id":451806,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Newman, Raymond","contributorId":172288,"corporation":false,"usgs":false,"family":"Newman","given":"Raymond","affiliations":[],"preferred":false,"id":451808,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Stefan, Heinz","contributorId":172289,"corporation":false,"usgs":false,"family":"Stefan","given":"Heinz","email":"","affiliations":[],"preferred":false,"id":451807,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Vondracek, Bruce C. bcv@usgs.gov","contributorId":904,"corporation":false,"usgs":true,"family":"Vondracek","given":"Bruce","email":"bcv@usgs.gov","middleInitial":"C.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":451804,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Recent work suggests that 5 elevated CO2 and temperature warming will increase organic matter productivity and the ability of marshes to survive sea level rise. However, we find that organic decomposition rates increase by about 12% per degree of warming. Our measured temperature sensitivity is similar to studies from terrestrial systems, twice as high as the response of salt marsh productivity to temperature warming, and roughly equivalent to the productivity response associated with elevated CO2 10 in C3 marsh plants. Therefore, enhanced CO2 and warmer temperatures may actually make marshes less resilient to sea level rise, and tend to promote a release of soil carbon.

An increase in specific conductance was related to a decrease in spawning success. In previous studies for streams in this region, specific conductance had a linear relation with chloride, suggesting the possibility that chloride could be a factor in egg production. Egg production was lower at sites with substantial urban development, but sites with low egg production were not limited to urban sites. Degradation of water- and sediment-quality parameters with increasing urban development is indicated for multiple parameters while patterns were not detected for others. Results from this study indicate that DO must be a high priority watershed management consideration for this region, specific conductance should be investigated further to determine the mechanism of the relation with egg production, and water- and sediment-quality degrade in relation to urban influence.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/j.scitotenv.2011.08.014","issn":"00489697","usgsCitation":"Corsi, S., Klaper, R., Weber, D., and Bannerman, R., 2011, Water- and sediment-quality effects on Pimephales promelas spawning vary along an agriculture-to-urban land-use gradient: Science of the Total Environment, v. 409, no. 22, p. 4847-4857, https://doi.org/10.1016/j.scitotenv.2011.08.014.","productDescription":"11 p.","startPage":"4847","endPage":"4857","costCenters":[],"links":[{"id":243442,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":215626,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.scitotenv.2011.08.014"}],"volume":"409","issue":"22","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bcce7e4b08c986b32ddaa","contributors":{"authors":[{"text":"Corsi, S.R.","contributorId":76346,"corporation":false,"usgs":true,"family":"Corsi","given":"S.R.","email":"","affiliations":[],"preferred":false,"id":446560,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Klaper, R.D.","contributorId":72114,"corporation":false,"usgs":true,"family":"Klaper","given":"R.D.","email":"","affiliations":[],"preferred":false,"id":446559,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Weber, D.N.","contributorId":15032,"corporation":false,"usgs":true,"family":"Weber","given":"D.N.","email":"","affiliations":[],"preferred":false,"id":446558,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Bannerman, R.T.","contributorId":92304,"corporation":false,"usgs":false,"family":"Bannerman","given":"R.T.","email":"","affiliations":[{"id":6913,"text":"Wisconsin Department of Natural Resources","active":true,"usgs":false}],"preferred":false,"id":446561,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

However, wood decay in dead trees may alter the δ<sup>13</sup>C and δ<sup>18</sup>O values of whole wood obscuring the isotopic signal associated with factors leading up to and including physiological death. We examined whole sapwood and α-cellulose from live and dead specimens of ponderosa pine (<i>Pinus ponderosa</i>), one-seed juniper (<i>Juniperous monosperma</i>), piñon pine (<i>Pinus edulis</i>) and white fir (<i>Abies concolor</i>), including those with fungal growth and beetle frass in the wood, to determine if α-cellulose extraction is necessary for the accurate interpretation of isotopic compositions in the dead trees. We found that the offset between the δ<sup>13</sup>C or δ<sup>18</sup>O values of α-cellulose and whole wood was the same for both live and dead trees across a large range of inter-annual and regional climate differences. The method of α-cellulose extraction, whether Leavitt-Danzer or Standard Brendel modified for small samples, imparts significant differences in the δ<sup>13</sup>C (up to 0.4‰) and δ<sup>18</sup>O (up to 1.2‰) of α-cellulose, as reported by other studies.

Historically, manatees were abundant in Mexico, but hunting during the pre-Columbian period, the Spanish colonization and throughout the history of Mexico, has resulted in the significantly reduced population occupying Mexico today. The genetic structure, using microsatellites, shows the presence of two populations in Mexico: the Gulf of Mexico (GMx) and Chetumal Bay (ChB) on the Caribbean coast, with a zone of admixture in between. Both populations show low genetic diversity (GMx: N</span><sub>A</sub><span>&nbsp;=&nbsp;2.69; H</span><sub>E</sub><span>&nbsp;=&nbsp;0.41 and ChB: N</span><sub>A</sub><span>&nbsp;=&nbsp;3.0; H</span><sub>E</sub><span>&nbsp;=&nbsp;0.46). The lower genetic diversity found in the GMx, the largest manatee population in Mexico, is probably due to a combination of a founder effect, as this is the northern range of the sub-species of&nbsp;</span><i>T. m. manatus</i><span>, and a bottleneck event. The greater genetic diversity observed along the Caribbean coast, which also has the smallest estimated number of individuals, is possibly due to manatees that come from the GMx and Belize. There is evidence to support limited or unidirectional gene flow between these two important areas. The analyses presented here also suggest minimal evidence of a handful of individual migrants possibly between Florida and Mexico. To address management issues we suggest considering two distinct genetic populations in Mexico, one along the Caribbean coast and one in the riverine systems connected to the GMx.</span></p>","language":"English","publisher":"Springer Link","doi":"10.1007/s10709-011-9583-z","issn":"00166707","usgsCitation":"Nourisson, C., Morales-Vela, B., Padilla-Saldivar, J., Tucker, K., Clark, A., Olivera-Gomez, L.D., Bonde, R.K., and McGuire, P., 2011, Evidence of two genetic clusters of manatees with low genetic diversity in Mexico and implications for their conservation: Genetica, v. 139, no. 7, p. 833-842, https://doi.org/10.1007/s10709-011-9583-z.","productDescription":"10 p.","startPage":"833","endPage":"842","costCenters":[],"links":[{"id":246364,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":218363,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10709-011-9583-z"}],"country":"Mexico","otherGeospatial":"Coastal waters of the Greater Antilles and Caribbean","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -98.525390625,\n              17.056784609942554\n            ],\n            [\n              -85.78125,\n              17.056784609942554\n            ],\n            [\n              -85.78125,\n              22.105998799750566\n            ],\n            [\n              -98.525390625,\n              22.105998799750566\n            ],\n            [\n              -98.525390625,\n              17.056784609942554\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"139","issue":"7","noUsgsAuthors":false,"publicationDate":"2011-06-17","publicationStatus":"PW","scienceBaseUri":"505a0d6fe4b0c8380cd52ffe","contributors":{"authors":[{"text":"Nourisson, C.","contributorId":103873,"corporation":false,"usgs":true,"family":"Nourisson","given":"C.","affiliations":[],"preferred":false,"id":454838,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Morales-Vela, B.","contributorId":32481,"corporation":false,"usgs":false,"family":"Morales-Vela","given":"B.","email":"","affiliations":[],"preferred":false,"id":454831,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Padilla-Saldivar, J.","contributorId":77403,"corporation":false,"usgs":true,"family":"Padilla-Saldivar","given":"J.","affiliations":[],"preferred":false,"id":454834,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Tucker, K.P.","contributorId":98449,"corporation":false,"usgs":true,"family":"Tucker","given":"K.P.","email":"","affiliations":[],"preferred":false,"id":454837,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Clark, A.","contributorId":50476,"corporation":false,"usgs":false,"family":"Clark","given":"A.","affiliations":[],"preferred":false,"id":454832,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Olivera-Gomez, L.

As part of its mission to facilitate technology transfer and develop guidelines from lessons learned, DOE is developing a series of best practice manuals (BPMs) for carbon capture and storage (CCS). The \"Site Screening, Site Selection, and Initial Characterization for Storage of CO<sub>2</sub> in Deep Geological Formations\" BPM is a compilation of best practices and includes flowchart diagrams illustrating the general decision making process for Site Screening, Site Selection, and Initial Characterization.

Key geologic and surface elements that suitable candidate storage sites should possess are identified, along with example Site Screening, Site Selection, and Initial Characterization protocols for large-scale geologic storage projects located across diverse geologic and regional settings. This manual has been written as a working document, establishing a framework and methodology for proper site selection for <span>CO</span><sub>2</sub>&nbsp;geologic storage. This will be useful for future <span>CO</span><sub>2</sub> emitters, transporters, and storage providers. It will also be of use in informing local, regional, state, and national governmental agencies of best practices in proper sequestration site selection. Furthermore, it will educate the inquisitive general public on options and processes for geologic <span>CO</span><sub>2</sub> storage. In addition to providing best practices, the manual presents a geologic storage resource and capacity classification system. The system provides a \"standard\" to communicate storage and capacity estimates, uncertainty and project development risk, data guidelines and analyses for adequate site characterization, and guidelines for reporting estimates within the classification based on each project's status.&nbsp;</p>","largerWorkTitle":"Energy Procedia","conferenceTitle":"10th International Conference on Greenhouse Gas Control Technologies","conferenceDate":"19 September 2010 through 23 September 2010","conferenceLocation":"Amsterdam","language":"English","doi":"10.1016/j.egypro.2011.02.427","issn":"18766102","usgsCitation":"Rodosta, T., Litynski, J., Plasynski, S., Hickman, S., Frailey, S., and Myer, L., 2011, U.S. Department of Energy's site screening, site selection, and initial characterization for storage of CO<sub>2</sub> in deep geological formations, <i>in</i> Energy Procedia, v. 4, Amsterdam, 19 September 2010 through 23 September 2010, p. 4664-4671, https://doi.org/10.1016/j.egypro.2011.02.427.","productDescription":"8 p.","startPage":"4664","endPage":"4671","costCenters":[],"links":[{"id":475383,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1016/j.egypro.2011.02.427","text":"Publisher Index Page"},{"id":242174,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bba3ee4b08c986b32806d","contributors":{"authors":[{"text":"Rodosta, T.D.","contributorId":30057,"corporation":false,"usgs":true,"family":"Rodosta","given":"T.D.","email":"","affiliations":[],"preferred":false,"id":443117,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Litynski, J.T.","contributorId":64043,"corporation":false,"usgs":true,"family":"Litynski","given":"J.T.","email":"","affiliations":[],"preferred":false,"id":443120,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Plasynski, S.I.","contributorId":48398,"corporation":false,"usgs":true,"family":"Plasynski","given":"S.I.","email":"","affiliations":[],"preferred":false,"id":443118,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hickman, S.","contributorId":79995,"corporation":false,"usgs":true,"family":"Hickman","given":"S.","email":"","affiliations":[],"preferred":false,"id":443122,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Frailey, S.","contributorId":66054,"corporation":false,"usgs":true,"family":"Frailey","given":"S.","email":"","affiliations":[],"preferred":false,"id":443121,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Myer, L.","contributorId":53182,"corporation":false,"usgs":true,"family":"Myer","given":"L.","email":"","affiliations":[],"preferred":false,"id":443119,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

In order to better predict human fatalities, the U.S. Geological Survey’s Prompt Assessment of Global Earthquakes for Response (PAGER) program requires collapse fragility functions for global building types. The collapse fragility is expressed as the probability of collapse at discrete levels of the input hazard defined in terms of macroseismic intensity. This article provides a simple procedure for quantifying collapse fragility using vulnerability criteria based on the European Macroseismic Scale (1998) for selected European building types. In addition, the collapse fragility functions are developed for global building types by fitting the beta distribution to the multiple experts’ estimates for the same building type (obtained from EERI’s World Housing Encyclopedia (WHE)-PAGER survey). Finally, using the collapse probability distributions at each shaking intensity level as a prior and field-based collapse-rate observations as likelihood, it is possible to update the collapse fragility functions for global building types using the Bayesian procedure.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Earthquake Spectra","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"EERI","doi":"10.1193/1.3606398","issn":"87552930","usgsCitation":"Jaiswal, K., Wald, D., and D’Ayala, D., 2011, Developing empirical collapse fragility functions for global building types: Earthquake Spectra, v. 27, no. 3, p. 775-795, https://doi.org/10.1193/1.3606398.","productDescription":"21 p.","startPage":"775","endPage":"795","costCenters":[{"id":415,"text":"National Earthquake Information Center","active":false,"usgs":true}],"links":[{"id":243917,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216075,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1193/1.3606398"}],"volume":"27","issue":"3","noUsgsAuthors":false,"publicationDate":"2011-08-01","publicationStatus":"PW","scienceBaseUri":"505a000fe4b0c8380cd4f57c","contributors":{"authors":[{"text":"Jaiswal, K.","contributorId":89260,"corporation":false,"usgs":true,"family":"Jaiswal","given":"K.","affiliations":[],"preferred":false,"id":452046,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wald, D. 0000-0002-1454-4514","orcid":"https://orcid.org/0000-0002-1454-4514","contributorId":37866,"corporation":false,"usgs":true,"family":"Wald","given":"D.","affiliations":[],"preferred":false,"id":452045,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"D’Ayala, D.","contributorId":15431,"corporation":false,"usgs":true,"family":"D’Ayala","given":"D.","email":"","affiliations":[],"preferred":false,"id":452044,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The invasive round goby <i>Neogobius melanostomus</i>, a benthic species, was first collected in trawl assessments in eastern Lake Erie in 1999, and was first found in stomachs of burbot in 2001. By 2003, round goby became an important prey in the diet of burbot. We hypothesized that the combined effects of low recruitment and consumption of round goby would result in increased size-at-age in burbot. We reasoned that: (i) decreased competition for resources among juveniles should result in larger adults, and (ii) consumption of a benthic prey by a bottom-dwelling predator such as burbot should require less foraging in the water column, and thus less energetic expenditure. We divided our data into two temporal periods: one in which burbot belonged to strong year classes and ate few, if any round goby (i.e., year classes 1989–1997 collected during 1997–2001) and one in which burbot belonged to weak year classes and probably ate round gobies by age 4 (year classes 1998–2003 collected during 2002–2007). Mass and total lengths at ages 4–7 were generally higher during the second period. However, the rates of growth between ages 4 and 7 were not different for the two periods. The results indicate that greater growth at ages 0–4 resulted in larger size at ages 4–7 in the latter period. More information on juvenile diet and growth in burbot is needed for effective conservation of burbot stocks.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Applied Ichthyology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1111/j.1439-0426.2011.01845.x","issn":"01758659","usgsCitation":"Stapanian, M., Edwards, W., and Witzel, L., 2011, Recent changes in burbot growth in Lake Erie: Journal of Applied Ichthyology, v. 27, no.

Adaptive management is an approach to natural resource management that emphasizes learning through management based on the philosophy that knowledge is incomplete and much of what we think we know is actually wrong. Adaptive management has explicit structure, including careful elucidation of goals, identification of alternative management objectives and hypotheses of causation, and procedures for the collection of data followed by evaluation and reiteration. It is evident that adaptive management has matured, but it has also reached a crossroads. Practitioners and scientists have developed adaptive management and structured decision making techniques, and mathematicians have developed methods to reduce the uncertainties encountered in resource management, yet there continues to be misapplication of the method and misunderstanding of its purpose. Ironically, the confusion over the term \"adaptive management\" may stem from the flexibility inherent in the approach, which has resulted in multiple interpretations of \"adaptive management\" that fall along a continuum of complexity and a priori design. Adaptive management is not a panacea for the navigation of 'wicked problems' as it does not produce easy answers, and is only appropriate in a subset of natural resource management problems where both uncertainty and controllability are high. Nonetheless, the conceptual underpinnings of adaptive management are simple; there will always be inherent uncertainty and unpredictability in the dynamics and behavior of complex social-ecological systems, but management decisions must still be made, and whenever possible, we should incorporate learning into management. ?? 2010 .","language":"English","publisher":"Elsevier","doi":"10.1016/j.jenvman.2010.11.019","usgsCitation":"Allen, C.R., Fontaine, J., Pope, K., and Garmestani, A., 2011, Adaptive management for a turbulent future: Journal of Environmental Management, v. 92, no. 5, p. 1339-1345, https://doi.org/10.1016/j.jenvman.2010.11.019.","productDescription":"7 p.","startPage":"1339","endPage":"1345","ipdsId":"IP-025896","costCenters":[],"links":[{"id":242175,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"92","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059e6e4e4b0c8380cd476e9","contributors":{"authors":[{"text":"Allen, Craig R. 0000-0001-8655-8272 allencr@usgs.gov","orcid":"https://orcid.org/0000-0001-8655-8272","contributorId":1979,"corporation":false,"usgs":true,"family":"Allen","given":"Craig","email":"allencr@usgs.gov","middleInitial":"R.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true},{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":443126,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fontaine, J.J.","contributorId":37940,"corporation":false,"usgs":true,"family":"Fontaine","given":"J.J.","email":"","affiliations":[],"preferred":false,"id":443124,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pope, K.L.","contributorId":20454,"corporation":false,"usgs":true,"family":"Pope","given":"K.L.","email":"","affiliations":[],"preferred":false,"id":443123,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Garmestani, A.S.","contributorId":86882,"corporation":false,"usgs":true,"family":"Garmestani","given":"A.S.","email":"","affiliations":[],"preferred":false,"id":443125,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Iron is an important redox substance, and its transfer and transformation in the wetland ecosystem could be an effective indicator for the environment changes. In this paper, we selected the Naoli River catchment in the Sanjiang Plain, Northeast China as the study area to analyze the dynamics of transfer and transformation of soil iron, and the relationship between iron content change and environmental factors. The results show that the total and crystalline iron contents reach the peak in the depth of 60 cm in soil profile, while the amorphous iron content is higher in the topsoil. In the upper reaches, from the low to high landscape positions, the total and crystalline iron contents decrease from 62.98 g/kg to 41.61 g/kg, 22.82 g/kg to 10.53 g/kg respectively, while the amorphous iron content increases from 2.42 g/kg to 8.88 g/kg. Amorphous iron content has positive correlation with organic matter and soil water contents, while negative correlation with pH. Moreover, both the crystalline and amorphous iron contents present no correlation with total iron content, indicating that environmental factors play a more important role in the transfer and transformation of iron other than the content of the total iron. Different redoximorphic features were found along the soil profile due to the transfer and transformation of iron. E and B horizons of wetland soil in the study area have a matrix Chroma 2 or less, and all the soil types can meet the criteria of American hydric soil indicators except albic soil. ??

In addition, maize productivity and field-life calculations were performed using organic-nitrogen (N) values from the upper 50 cm of soil in each region and a range (1-3%/year) of N-mineralization rates. The endmember values of this range were assumed representative of dry and wet climate states. With respect to precipitation and heat, the Pajarito Plateau area has excellent agricultural potential; the agricultural potentials of the Zuni and Mesa Verde regions are good; and the agricultural potential of the Chaco Halo is poor. Calculations of N mineralization and field life indicate that Morfield Valley in Mesa Verde should be able to provide 10 bu/ac of maize for decades (without the addition of N) when organic N-mineralization rates exceed 2%. Productivity and field-life potential decrease in the following order: Zuni, Mesa Verde, Bandelier, Chaco Halo.

The primary goal of this study was to evaluate the prevalence of <i>N. salmonis</i> in out-migrating juvenile hatchery and wild Chinook salmon <i>Oncorhynchus tshawytscha</i> and steelhead <i>O. mykiss</i> from the Snake River in the U.S. Pacific Northwest. To achieve this goal, we first addressed the following concerns about current molecular diagnostic tests for <i>N. salmonis</i>: (1) nonspecific amplification patterns by the published nested polymerase chain reaction (nPCR) test, (2) incomplete validation of the published quantitative PCR (qPCR) test, and (3) whether <i>N. salmonis</i> can be detected reliably from nonlethal samples. Here, we present an optimized nPCR protocol that eliminates nonspecific amplification. During validation of the published qPCR test, our laboratory developed a second qPCR test that targeted a different gene sequence and used different probe chemistry for comparison purposes. We simultaneously evaluated the two different qPCR tests for <i>N. salmonis</i> and found that both assays were highly specific, sensitive, and repeatable. The nPCR and qPCR tests had good overall concordance when DNA samples derived from both apparently healthy and clinically diseased hatchery rainbow trout were tested. Finally, we demonstrated that gill snips were a suitable tissue for nonlethal detection of <i>N. salmonis</i> DNA in juvenile salmonids. Monitoring of juvenile salmonid fish in the Snake River over a 3-year period revealed low prevalence of <i>N. salmonis</i> in hatchery and wild Chinook salmon and wild steelhead but significantly higher prevalence in hatchery-derived steelhead. Routine monitoring of <i>N. salmonis</i> is not performed for all hatchery steelhead populations. At present, the possible contribution of this pathogen to delayed mortality of steelhead has not been determined.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Aquatic Animal Health","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis","publisherLocation":"London, UK","doi":"10.1080/08997659.2011.559418","issn":"08997659","usgsCitation":"Badil, S., Elliott, D.G., Kurobe, T., Hedrick, R.P., Clemens, K., Blair, M., and Purcell, M., 2011, Comparative evaluation of molecular diagnostic tests for <i>Nucleospora salmonis</i> and prevalence in migrating juvenile salmonids from the Snake River, USA: Journal of Aquatic Animal Health, v. 23, no. 1, p. 19-29, https://doi.org/10.1080/08997659.2011.559418.","productDescription":"11 p.","startPage":"19","endPage":"29","costCenters":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"links":[{"id":244665,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":216776,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/08997659.2011.559418"}],"volume":"23","issue":"1","noUsgsAuthors":false,"publicationDate":"2011-03-09","publicationStatus":"PW","scienceBaseUri":"5059f80fe4b0c8380cd4ce67","contributors":{"authors":[{"text":"Badil, Samantha","contributorId":63241,"corporation":false,"usgs":true,"family":"Badil","given":"Samantha","affiliations":[],"preferred":false,"id":443560,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Elliott, Diane G. 0000-0002-4809-6692 dgelliott@usgs.gov","orcid":"https://orcid.org/0000-0002-4809-6692","contributorId":2947,"corporation":false,"usgs":true,"family":"Elliott","given":"Diane","email":"dgelliott@usgs.gov","middleInitial":"G.","affiliations":[{"id":654,"text":"Western Fisheries Research Center","active":true,"usgs":true}],"preferred":true,"id":443558,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Kurobe, Tomofumi","contributorId":97741,"corporation":false,"usgs":true,"family":"Kurobe","given":"Tomofumi","affiliations":[],"preferred":false,"id":443563,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hedrick, Ronald P.","contributorId":86999,"corporation":false,"usgs":true,"family":"Hedrick","given":"Ronald","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":443562,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Clemens, Kathy","contributorId":78172,"corporation":false,"usgs":true,"family":"Clemens","given":"Kathy","email":"","affiliations":[],"preferred":false,"id":443561,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Blair, Marilyn","contributorId":44388,"corporation":false,"usgs":true,"family":"Blair","given":"Marilyn","affiliations":[],"preferred":false,"id":443559,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Purcell, Maureen K.","contributorId":104214,"corporation":false,"usgs":true,"family":"Purcell","given":"Maureen K.","affiliations":[],"preferred":false,"id":443564,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}
