In the lower third of the formation, arkosic sandstone and conglomerate are interstratified with tuffaceous deposits.  Some tuffs might have been deposited as primary, nonwelded to partially welded ignimbrites or fallout tephra.  Many of the tuffaceous deposits represent redeposited material that formed tuffaceous sandstone, and many of these deposits contain arkosic grains that represent mixing of different source matieral.  Arkosic sandstone, and especially conglomerate (some with maximum clast lengths up to 1 m), represent intermittent incursions of coarser plutoniclastic fan deposits into other finer grained and mostly volcaniclastic basin deposits.  After deposition of the 18.78 Ma Peach Spring Tuff, the amount of tuffaceous material decreased.  The upper two-thirds of the formation has arkosic sandstone and conglomerate interstratified with two olivine basalt lave flows.  locally, conglomerate clasts in this part of the section have maximum lengths up to 1 m.  Many tuffaceous and arkosic sandstone beds of the Spanish Canyon Formation have tabular to broad (low-relief) lenticular geometry, and locally, some arkosic conglomerate fills channels as much as 1.5 m deep.  These bedforms are consistent with deposition in medial to distal alluvial-fan or fluvial environments; some finer-grained deposits might have formed in lacustrine environments.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"2014 Desert Symposium proceedings: not a drop left to drink","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"2014 Desert Symposium","conferenceDate":"April 18, 2014","conferenceLocation":"Baker, CA","language":"English","publisher":"California State University Desert Studies Center","publisherLocation":"Fullerton, CA","usgsCitation":"Buesch, D.C., 2014, Interstratified arkosic and volcanic rocks of the Miocene Spanish Canyon Formation, Alvord Mountain area, California: Descriptions and interpretations, <i>in</i> 2014 Desert Symposium proceedings: not a drop left to drink, Baker, CA, April 18, 2014, p. 190-203.","productDescription":"14 p.","startPage":"190","endPage":"203","numberOfPages":"14","ipdsId":"IP-054834","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":289386,"rank":2,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":289385,"rank":1,"type":{"id":15,"text":"Index Page"},"url":"https://biology.fullerton.edu/dsc/school/symposium.html"}],"country":"United States","state":"California","otherGeospatial":"Alvord Mountain","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.747255,35.024414 ], [ -116.747255,35.170481 ], [ -116.491136,35.170481 ], [ -116.491136,35.024414 ], [ -116.747255,35.024414 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53b7b190e4b0388651d917cf","contributors":{"authors":[{"text":"Buesch, David C. 0000-0002-4978-5027 dbuesch@usgs.gov","orcid":"https://orcid.org/0000-0002-4978-5027","contributorId":1154,"corporation":false,"usgs":true,"family":"Buesch","given":"David","email":"dbuesch@usgs.gov","middleInitial":"C.","affiliations":[{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true},{"id":309,"text":"Geology and Geophysics Science Center","active":true,"usgs":true},{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":490777,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Identifying where and when accelerated erosion occurs is a critical first step toward its effective management. Here we explore how erosion assessments structured in the context of ecological sites (a land classification based on soils, landscape setting and ecological potential) and their vegetation states (plant assemblages that may change due to management) can inform systems for reducing accelerated soil erosion in rangelands. We evaluated aeolian horizontal sediment flux and fluvial sediment erosion rates for five ecological sites in southern New Mexico, USA, using monitoring data and rangeland-specific wind and water erosion models. Across the ecological sites, plots in shrub-encroached and shrub-dominated vegetation states were consistently susceptible to aeolian sediment flux and fluvial sediment erosion. Both processes were found to be highly variable for grassland and grass-succulent states across the ecological sites at the plot scale (0.25 Ha). We identify vegetation thresholds that define cover levels below which rapid (exponential) increases in aeolian sediment flux and fluvial sediment erosion occur across the ecological sites and vegetation states. Aeolian sediment flux and fluvial erosion in the study area can be effectively controlled when bare ground cover is <20% of a site or the cover of canopy interspaces >100 cm in length is less than ~35%. Land use and management activities that alter cover levels such that they cross thresholds, and/or drive vegetation state changes, may increase the susceptibility of areas to erosion. Land use impacts that are constrained within the range of natural variability should not result in accelerated soil erosion. Evaluating land condition against the erosion thresholds identified here will enable identification of areas susceptible to accelerated soil erosion and the development of practical management solutions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ecological Society of America","doi":"10.1890/13-1175.1","usgsCitation":"Webb, N., Herrick, J.E., and Duniway, M.C., 2014, Ecological site-based assessments of wind and water erosion: informing accelerated soil erosion management in rangelands: Ecological Applications, v. 24, no. 6, p. 1405-1420, https://doi.org/10.1890/13-1175.1.","productDescription":"16 p.","startPage":"1405","endPage":"1420","numberOfPages":"16","ipdsId":"IP-050767","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":282605,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282604,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/13-1175.1"}],"country":"United States","state":"New Mexico","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -106.2048,32.1 ], [ -106.2048,32.7018 ], [ -105.4578,32.7018 ], [ -105.4578,32.1 ], [ -106.2048,32.1 ] ] ] } } ] }","volume":"24","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd564de4b0b290850f6d50","contributors":{"authors":[{"text":"Webb, Nicholas P.","contributorId":81409,"corporation":false,"usgs":true,"family":"Webb","given":"Nicholas P.","affiliations":[],"preferred":false,"id":490651,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Herrick, Jeffrey E.","contributorId":26054,"corporation":false,"usgs":false,"family":"Herrick","given":"Jeffrey","email":"","middleInitial":"E.","affiliations":[{"id":12627,"text":"USDA-ARS Jornada Experimental Range, New Mexico State University, Las Cruces, NM 88003-8003, USA","active":true,"usgs":false}],"preferred":false,"id":490650,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Duniway, Michael C. 0000-0002-9643-2785 mduniway@usgs.gov","orcid":"https://orcid.org/0000-0002-9643-2785","contributorId":4212,"corporation":false,"usgs":true,"family":"Duniway","given":"Michael","email":"mduniway@usgs.gov","middleInitial":"C.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":490649,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Our case study concerns the management of human recreational activities in Alaska’s Denali National Park, USA, and the possible impacts of such activities on nesting Golden Eagles, Aquila chrysaetos. Managers desire to allow visitors the greatest amount of access to park lands, provided that eagle nesting-site occupancy is maintained at a level determined to be acceptable by the managers themselves. As these two management objectives are potentially at odds, we treat minimum desired occupancy level as a utility threshold which, then, serves to guide the selection of annual management alternatives in the decision process. As human disturbance is not the only factor influencing eagle occupancy, we model nesting-site dynamics as a function of both disturbance and prey availability. We incorporate uncertainty in these dynamics by considering several hypotheses, including a hypothesis that site occupancy is affected only at a threshold level of prey abundance (i.e., an ecological threshold effect). By considering competing management objectives and accounting for two forms of thresholds in the decision process, we are able to determine the optimal number of annual nesting-site restrictions that will produce the greatest long-term benefits for both eagles and humans. Setting a utility threshold of 75 occupied sites, out of a total of 90 potential nesting sites, the optimization specified a decision threshold at approximately 80 occupied sites. At the point that current occupancy falls below 80 sites, the recommended decision is to begin restricting access to humans; above this level, it is recommended that all eagle territories be opened to human recreation. We evaluated the sensitivity of the decision threshold to uncertainty in system dynamics and to management objectives (i.e., to the utility threshold).","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Application of threshold concepts in natural resource decision making","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Springer","doi":"10.1007/978-1-4899-8041-0_5","usgsCitation":"Eaton, M., Martin, J., Nichols, J., McIntyre, C., McCluskie, M.C., Schmutz, J.A., Lubow, B.L., and Runge, M.C., 2014, Application of threshold concepts to ecological management problems: Occupancy of Golden Eagles in Denali National Park, Alaska, chap. 5 <i>of</i> Application of threshold concepts in natural resource decision making, p. 67-86, https://doi.org/10.1007/978-1-4899-8041-0_5.","productDescription":"20 p.","startPage":"67","endPage":"86","ipdsId":"IP-035575","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":284416,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Alaska","otherGeospatial":"Denali National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -151.01,63.17 ], [ -151.01,63.49 ], [ -149.99,63.49 ], [ -149.99,63.17 ], [ -151.01,63.17 ] ] ] } } ] }","noUsgsAuthors":false,"publicationDate":"2014-02-08","publicationStatus":"PW","scienceBaseUri":"5351701ee4b05569d805a154","contributors":{"editors":[{"text":"Guntenspergen, Glenn R.","contributorId":113070,"corporation":false,"usgs":false,"family":"Guntenspergen","given":"Glenn R.","affiliations":[],"preferred":false,"id":509828,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Eaton, Mitchell J.","contributorId":71308,"corporation":false,"usgs":true,"family":"Eaton","given":"Mitchell J.","affiliations":[],"preferred":false,"id":491925,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Martin, Julien 0000-0002-7375-129X julienmartin@usgs.gov","orcid":"https://orcid.org/0000-0002-7375-129X","contributorId":5785,"corporation":false,"usgs":true,"family":"Martin","given":"Julien","email":"julienmartin@usgs.gov","affiliations":[{"id":566,"text":"Southeast Ecological Science Center","active":true,"usgs":true},{"id":17705,"text":"Wetland and Aquatic Research Center","active":true,"usgs":true}],"preferred":true,"id":491921,"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":491918,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McIntyre, Carol","contributorId":12363,"corporation":false,"usgs":true,"family":"McIntyre","given":"Carol","affiliations":[],"preferred":false,"id":491922,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"McCluskie, Maggie C.","contributorId":57730,"corporation":false,"usgs":true,"family":"McCluskie","given":"Maggie","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":491924,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Schmutz, Joel A. 0000-0002-6516-0836 jschmutz@usgs.gov","orcid":"https://orcid.org/0000-0002-6516-0836","contributorId":1805,"corporation":false,"usgs":true,"family":"Schmutz","given":"Joel","email":"jschmutz@usgs.gov","middleInitial":"A.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":117,"text":"Alaska Science Center Biology WTEB","active":true,"usgs":true}],"preferred":true,"id":491919,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Lubow, Bruce L.","contributorId":54474,"corporation":false,"usgs":true,"family":"Lubow","given":"Bruce","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":491923,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Runge, Michael C. 0000-0002-8081-536X mrunge@usgs.gov","orcid":"https://orcid.org/0000-0002-8081-536X","contributorId":3358,"corporation":false,"usgs":true,"family":"Runge","given":"Michael","email":"mrunge@usgs.gov","middleInitial":"C.","affiliations":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"preferred":true,"id":491920,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

However, much of the helium emitted from this region is actually radiogenic helium-4 produced within the crust by &alpha;-decay of uranium and thorium. Here we show, by combining gas emission rates with chemistry and isotopic analyses, that crustal helium-4 emission rates from Yellowstone exceed (by orders of magnitude) any conceivable rate of generation within the crust. It seems that helium has accumulated for (at least) many hundreds of millions of years in Archaean (more than 2.5 billion years old) cratonic rocks beneath Yellowstone, only to be liberated over the past two million years by intense crustal metamorphism induced by the Yellowstone hotspot. Our results demonstrate the extremes in variability of crustal helium efflux on geologic timescales and imply crustal-scale open-system behaviour of helium in tectonically and magmatically active regions.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Nature","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Macmillan Publishers Limited","doi":"10.1038/nature12992","usgsCitation":"Lowenstern, J.B., Evans, W.C., Bergfeld, D., and Hunt, A.G., 2014, Prodigious degassing of a billion years of accumulated radiogenic helium at Yellowstone: Nature, v. 506, p. 355-358, https://doi.org/10.1038/nature12992.","productDescription":"4 p.","startPage":"355","endPage":"358","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-050861","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":283862,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Wyoming","otherGeospatial":"Yellowstone National Park","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -111.16790771484375,\n              44.1289994645142\n            ],\n            [\n              -111.16790771484375,\n              45.11811475546806\n            ],\n            [\n              -109.8248291015625,\n              45.11811475546806\n            ],\n            [\n              -109.8248291015625,\n              44.1289994645142\n            ],\n            [\n              -111.16790771484375,\n              44.1289994645142\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"506","noUsgsAuthors":false,"publicationDate":"2014-02-19","publicationStatus":"PW","scienceBaseUri":"54e322bde4b08de9379b4f8c","contributors":{"authors":[{"text":"Lowenstern, Jacob B. 0000-0003-0464-7779 jlwnstrn@usgs.gov","orcid":"https://orcid.org/0000-0003-0464-7779","contributorId":2755,"corporation":false,"usgs":true,"family":"Lowenstern","given":"Jacob","email":"jlwnstrn@usgs.gov","middleInitial":"B.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":487062,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Evans, William C. 0000-0001-5942-3102 wcevans@usgs.gov","orcid":"https://orcid.org/0000-0001-5942-3102","contributorId":2353,"corporation":false,"usgs":true,"family":"Evans","given":"William","email":"wcevans@usgs.gov","middleInitial":"C.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":487065,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bergfeld, D. dbergfel@usgs.gov","contributorId":2069,"corporation":false,"usgs":true,"family":"Bergfeld","given":"D.","email":"dbergfel@usgs.gov","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":false,"id":487063,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hunt, Andrew G. 0000-0002-3810-8610 ahunt@usgs.gov","orcid":"https://orcid.org/0000-0002-3810-8610","contributorId":1582,"corporation":false,"usgs":true,"family":"Hunt","given":"Andrew","email":"ahunt@usgs.gov","middleInitial":"G.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":487064,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Land-management practices with the objective of limiting the amount of salt and selenium that reaches the stream have focused on improving the methods by which irrigation water is conveyed and distributed. Federal land managers implement improvements in accordance with the Colorado River Basin Salinity Control Act of 1974, which directs Federal land managers to enhance and protect the quality of water available in the Colorado River. In an effort to assist in evaluating and mitigating the detrimental effects of salinity and selenium, the U.S. Geological Survey, in cooperation with the Bureau of Reclamation, the Colorado River Water Resources District, and the Bureau of Land Management, analyzed salinity and selenium data collected at sites to develop regression models. The study area and sites are on the Colorado River or in one of three small basins in Western Colorado: the White River Basin, the Lower Gunnison River Basin, and the Dolores River Basin. By using data collected from water years 2009 through 2011, regression models able to estimate concentrations were developed for salinity at six sites and selenium at six sites. At a minimum, data from discrete measurement of salinity or selenium concentration, streamflow, and specific conductance at each of the sites were needed for model development. Comparison of the <i>Adjusted R<sup>2</sup></i> and standard error statistics of the two salinity models developed at each site indicated the models using specific conductance as the explanatory variable performed better than those using streamflow. The addition of multiple explanatory variables improved the ability to estimate selenium concentration at several sites compared with use of solely streamflow or specific conductance. The error associated with the log-transformed salinity and selenium estimates is consistent in log space; however, when the estimates are transformed into non-log values, the error increases as the estimates decrease. Continuous streamflow and specific conductance data collected at study sites provide the means to examine temporal variability in constituent concentration and load. The regression models can estimate continuous concentrations or loads on the basis of continuous specific conductance or streamflow data. Similar estimates are available for other sites at the USGS National Real-Time Water Quality Web page (<a href=\"http://nrtwq.usgs.gov\" target=\"_blank\">http://nrtwq.usgs.gov</a>) and provide water-resource managers with a means of improving their general understanding of how constituent concentration or load can change annually, seasonally, or in real time.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20141015","collaboration":"Prepared in cooperation with the Bureau of Reclamation, the Colorado River Water Resources District, and the Bureau of Land Management","usgsCitation":"Linard, J.I., and Schaffrath, K.R., 2014, Regression models for estimating salinity and selenium concentrations at selected sites in the Upper Colorado River Basin, Colorado, 2009-2012: U.S. Geological Survey Open-File Report 2014-1015, v, 28 p., https://doi.org/10.3133/ofr20141015.","productDescription":"v, 28 p.","numberOfPages":"34","onlineOnly":"Y","additionalOnlineFiles":"N","temporalStart":"2008-10-01","temporalEnd":"2011-09-30","ipdsId":"IP-051865","costCenters":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"links":[{"id":282585,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr20141015.jpg"},{"id":282578,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2014/1015/"},{"id":282584,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2014/1015/pdf/of2014-1015.pdf"}],"datum":"North American Datum 1983","country":"United States","state":"Colorado","otherGeospatial":"Colorado River, Dolores River Basin, Lower Gunnison River Basin, Upper Colorado River Basin, White River Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -109.05,\n              38\n            ],\n            [\n              -109.05,\n              40.5\n            ],\n            [\n              -107.1,\n              40.5\n            ],\n            [\n              -107.1,\n              38\n            ],\n            [\n              -109.05,\n              38\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd700de4b0b29085106cd2","contributors":{"authors":[{"text":"Linard, Joshua I. jilinard@usgs.gov","contributorId":1465,"corporation":false,"usgs":true,"family":"Linard","given":"Joshua","email":"jilinard@usgs.gov","middleInitial":"I.","affiliations":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"preferred":true,"id":489564,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schaffrath, Keelin R.","contributorId":7552,"corporation":false,"usgs":true,"family":"Schaffrath","given":"Keelin","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":489565,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Although commonly thought to have diversified over the Cenozoic as global oceans cooled, only two conflicting quantitative reconstructions exist, both from the Neptune deep-sea microfossil occurrences database. Total diversity shows Cenozoic increase but is sample size biased; conventional subsampling shows little net change. We calculate diversity from a separately compiled new diatom species range catalog, and recalculate Neptune subsampled-in-bin diversity using new methods to correct for increasing Cenozoic geographic endemism and decreasing Cenozoic evenness. We find coherent, substantial Cenozoic diversification in both datasets. Many living cold water species, including species important for export productivity, originate only in the latest Miocene or younger. We make a first quantitative comparison of diatom diversity to the global Cenozoic benthic ∂<sup>18</sup>O (climate) and carbon cycle records (∂<sup>13</sup>C, and 20-0 Ma pCO<sub>2</sub>). Warmer climates are strongly correlated with lower diatom diversity (raw: rho = .92, p<.001; detrended, r = .6, p = .01). Diatoms were 20% less diverse in the early late Miocene, when temperatures and pCO<sub>2</sub> were only moderately higher than today. Diversity is strongly correlated to both ∂<sup>13</sup>C and pCO<sub>2</sub> over the last 15 my (for both: r>.9, detrended r>.6, all p<.001), but only weakly over the earlier Cenozoic, suggesting increasingly strong linkage of diatom and climate evolution in the Neogene. Our results suggest that many living marine planktonic diatom species may be at risk of extinction in future warm oceans, with an unknown but potentially substantial negative impact on the ocean biologic pump and oceanic carbon sequestration. We cannot however extrapolate our my-scale correlations with generic climate proxies to anthropogenic time-scales of warming without additional species-specific information on proximate ecologic controls.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"PLoS ONE","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Public Library of Science","publisherLocation":"San Francisco, CA","doi":"10.1371/journal.pone.0084857","usgsCitation":"Lazarus, D., Barron, J., Renaudie, J., Diver, P., and Turke, A., 2014, Cenozoic planktonic marine diatom diversity and correlation to climate change: PLoS ONE, v. 9, no. 1, 8 p., https://doi.org/10.1371/journal.pone.0084857.","productDescription":"8 p.","numberOfPages":"8","onlineOnly":"Y","costCenters":[],"links":[{"id":473169,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1371/journal.pone.0084857","text":"Publisher Index Page"},{"id":282560,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282559,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1371/journal.pone.0084857"}],"volume":"9","issue":"1","noUsgsAuthors":false,"publicationDate":"2014-01-22","publicationStatus":"PW","scienceBaseUri":"5351702be4b05569d805a18a","contributors":{"authors":[{"text":"Lazarus, David","contributorId":71877,"corporation":false,"usgs":true,"family":"Lazarus","given":"David","email":"","affiliations":[],"preferred":false,"id":490609,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barron, John","contributorId":87059,"corporation":false,"usgs":true,"family":"Barron","given":"John","affiliations":[],"preferred":false,"id":490610,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Renaudie, Johan","contributorId":17908,"corporation":false,"usgs":true,"family":"Renaudie","given":"Johan","email":"","affiliations":[],"preferred":false,"id":490607,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Diver, Patrick","contributorId":41329,"corporation":false,"usgs":true,"family":"Diver","given":"Patrick","email":"","affiliations":[],"preferred":false,"id":490608,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Turke, Andreas","contributorId":97419,"corporation":false,"usgs":true,"family":"Turke","given":"Andreas","email":"","affiliations":[],"preferred":false,"id":490611,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Of these 746 sites, 408 sites are in the Silverton Caldera area of the San Juan Mountains of southwestern Colorado. Of the 408 sites in the Silverton Caldera area, 106 sites are underground. The remaining 338 sites outside the Silverton Caldera area were on outcropping rock, are distributed from southern Arizona to northwestern Wyoming, and include data from California, Nevada, Utah, Colorado, and New Mexico. Rock-density measurements are included for some sites. These data have been collected by various U.S. Geological Survey studies from 1991 through 2012 and are intended to help improve geophysical modeling of the Earth’s crust in the Western United States. A map-based graphical user interface is included to facilitate use of the data.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston,

The base is located within the State of Idaho's Mountain Home Groundwater Management Area and is adjacent to the State's Cinder Cone Butte Critical Groundwater Area. Both areas were established by the Idaho Department of Water Resources in the early 1980s because of declining water levels in the regional aquifer. The base also is listed by the Idaho Department of Environmental Quality as a nitrate priority area.</p>\n<br/>\n<p>The U.S. Geological Survey, in cooperation with the U.S. Air Force, began monitoring wells on the base in 1985, and currently monitors 25 wells for water levels and 17 wells for water quality, primarily nutrients. This report provides a summary of water-level and nitrate concentration data collected primarily between 2001 and 2013 and examines trends in those data.</p>\n<br/>\n<p>A Regional Kendall Test was run to combine results from all wells to determine an overall regional trend in water level.

Central to many wildlife assessments is the use of geospatial methods that rely on digital representation of energy infrastructure. Surface disturbance of the well pad scars associated with oil and natural gas extraction has been an important but unavailable infrastructure layer. To provide a digital baseline of this surface disturbance, we extracted visible oil and gas well pad scars from 1-meter National Agriculture Imagery Program imagery (NAIP) acquired in 2009 for a 7.7 million-hectare region of southwest Wyoming. Scars include the pad area where wellheads, pumps, and storage facilities reside, and the surrounding area that was scraped and denuded of vegetation during the establishment of the pad. Scars containing tanks, compressors, and the storage of oil and gas related equipment, and produced-water ponds were also collected on occasion. Our extraction method was a two-step process starting with automated extraction followed by manual inspection and clean up. We used available well-point information to guide manual clean up and to derive estimates of year of origin and duration of activity on a pad scar. We also derived estimates of the proportion of non-vegetated area on a scar using a Normalized Difference Vegetation Index derived using 1-meter NAIP imagery. We extracted 16,973 pad scars of which 15,318 were oil and gas well pads. Digital representation of pad scars along with time-stamps of activity and estimates of non-vegetated area provides important baseline (circa 2009) data for assessments of wildlife responses, land-use trends, and disturbance-mediated pattern assessments.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ds800","usgsCitation":"Garman, S.L., and McBeth, J.L., 2014, Digital representation of oil and natural gas well pad scars in southwest Wyoming: U.S. Geological Survey Data Series 800, Report: iv, 7 p.; Downloads Directory, https://doi.org/10.3133/ds800.","productDescription":"Report: iv, 7 p.; Downloads Directory","numberOfPages":"14","onlineOnly":"Y","additionalOnlineFiles":"Y","ipdsId":"IP-039038","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":282545,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/ds/800/"},{"id":282547,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/ds/800/downloads/"},{"id":282546,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/ds/800/pdf/ds800.pdf"},{"id":282548,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ds800.jpg"}],"country":"United States","state":"Wyoming","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -0.01638888888888889,0.0011111111111111111 ], [ -0.01638888888888889,0.0011111111111111111 ], [ -0.016666666666666666,0.0011111111111111111 ], [ -0.016666666666666666,0.0011111111111111111 ], [ -0.01638888888888889,0.0011111111111111111 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5511e4b0b290850f61cb","contributors":{"authors":[{"text":"Garman, Steven L. 0000-0002-9032-9074 slgarman@usgs.gov","orcid":"https://orcid.org/0000-0002-9032-9074","contributorId":3741,"corporation":false,"usgs":true,"family":"Garman","given":"Steven","email":"slgarman@usgs.gov","middleInitial":"L.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":485885,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McBeth, Jamie L. 0000-0002-7688-7985 jlmcbeth@usgs.gov","orcid":"https://orcid.org/0000-0002-7688-7985","contributorId":1254,"corporation":false,"usgs":true,"family":"McBeth","given":"Jamie","email":"jlmcbeth@usgs.gov","middleInitial":"L.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":485884,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The present study was initiated to investigate the chronic toxicity and define sublethal effects at the individual organism level to explain the mechanisms of NaHCO<sub>3</sub> toxicity. Three chronic experiments were completed with fathead minnows (Pimephales promelas), 1 with white suckers (Catostomus commersoni), 1 with Ceriodaphnia dubia, and 1 with a freshwater mussel, (Lampsilis siliquoidea). The data demonstrated that approximately 500 mg NaHCO<sub>3</sub>/L to 1000 mg NaHCO<sub>3</sub>/L affected all species of experimental aquatic animals in chronic exposure conditions. Freshwater mussels were the least sensitive to NaHCO<sub>3</sub> exposure, with a 10-d inhibition concentration that affects 20% of the sample population (IC20) of 952 mg NaHCO<sub>3</sub>/L. The IC20 for C. dubia was the smallest, at 359 mg NaHCO<sub>3</sub>/L. A significant decrease in sodium–potassium adenosine triphosphatase (Na<sup>+</sup>/K<sup>+</sup> ATPase) together with the lack of growth effects suggests that Na<sup>+</sup>/K<sup>+</sup> ATPase activity was shut down before the onset of death.

However, native plant restoration efforts often remain unguided by ecological genetic information. Given that many ecosystems are in flux from climate change, restoration plans need to account for both contemporary and future climates when choosing seed sources. In this study we analyze vegetative responses, including mortality, growth, and carbon isotope ratios in two blackbrush (Coleogyne ramosissima) common gardens that included 26 populations from a range-wide collection. This shrub occupies ecotones between the warm and cold deserts of Mojave and Colorado Plateau ecoregions in western North America. The variation observed in the vegetative responses of blackbrush populations was principally explained by grouping populations by ecoregions and by regression with site-specific climate variables. Aridity weighted by winter minimum temperatures best explained vegetative responses; Colorado Plateau sites were usually colder and drier than Mojave sites. The relationship between climate and vegetative response was mapped within the boundaries of the species–climate space projected for the contemporary climate and for the decade surrounding 2060. The mapped ecological genetic pattern showed that genetic variation could be classified into cool-adapted and warm-adapted ecotypes, with populations often separated by steep clines. These transitions are predicted to occur in both the Mojave Desert and Colorado Plateau ecoregions. While under contemporary conditions the warm-adapted ecotype occupies the majority of climate space, climate projections predict that the cool-adapted ecotype could prevail as the dominant ecotype as the climate space of blackbrush expands into higher elevations and latitudes. This study provides the framework for delineating climate change-responsive seed transfer guidelines, which are needed to inform restoration and management planning. We propose four transfer zones in blackbrush that correspond to areas currently dominated by cool-adapted and warm-adapted ecotypes in each of the two ecoregions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecological Applications","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ecological Society of America","doi":"10.1890/13-0587.1","usgsCitation":"Richardson, B., Kitchen, S.G., Pendleton, R.L., Pendleton, B.K., Germino, M., Rehfeldt, G.E., and Meyer, S.E., 2014, Adaptive responses reveal contemporary and future ecotypes in a desert shrub: Ecological Applications, v. 24, no. 2, p. 413-427, https://doi.org/10.1890/13-0587.1.","productDescription":"15 p.","startPage":"413","endPage":"427","numberOfPages":"15","ipdsId":"IP-049665","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":282515,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282508,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1890/13-0587.1"}],"country":"United States","state":"Arizona;California;Colorado;Nevada;New Mexico;Utah","otherGeospatial":"Colorado Plateau;Mojave Desert","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120.0,30.0 ], [ -120.0,40.0 ], [ -110.0,40.0 ], [ -110.0,30.0 ], [ -120.0,30.0 ] ] ] } } ] }","volume":"24","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53516f2ce4b05569d805a029","contributors":{"authors":[{"text":"Richardson, Bryce A.","contributorId":37249,"corporation":false,"usgs":true,"family":"Richardson","given":"Bryce A.","affiliations":[],"preferred":false,"id":490569,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kitchen, Stanley G.","contributorId":60530,"corporation":false,"usgs":true,"family":"Kitchen","given":"Stanley","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":490571,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pendleton, Rosemary L.","contributorId":69882,"corporation":false,"usgs":true,"family":"Pendleton","given":"Rosemary","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":490572,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Pendleton, Burton K.","contributorId":107187,"corporation":false,"usgs":true,"family":"Pendleton","given":"Burton","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":490574,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Germino, Matthew J.","contributorId":50029,"corporation":false,"usgs":true,"family":"Germino","given":"Matthew J.","affiliations":[],"preferred":false,"id":490570,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Rehfeldt, Gerald E.","contributorId":89439,"corporation":false,"usgs":true,"family":"Rehfeldt","given":"Gerald","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":490573,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Meyer, Susan E.","contributorId":20251,"corporation":false,"usgs":true,"family":"Meyer","given":"Susan","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":490568,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

This is surprising because of the frequent occurrence of such events and the potential for both the severity and frequency of disturbances to increase as a result of climate change. We investigated the impacts of low-severity canopy disturbance and average insect defoliation on forest carbon stocks and rates of carbon sequestration in mature aspen mixedwood forests of varying stand age (ranging from 61 to 85 years), overstory composition, stocking level, and site quality. Stocking level and site quality positively affected the average annual aboveground tree carbon increment (C<sub>AAI</sub>), while stocking level, site quality, and stand age positively affected tree carbon stocks (C<sub>TREE</sub>) and total ecosystem carbon stocks (C<sub>TOTAL</sub>). Cumulative canopy disturbance (DIST) was reconstructed using dendroecological methods over a 29-year period. DIST was negatively and significantly related to soil carbon (C<sub>SOIL</sub>), and it was negatively, albeit marginally, related to C<sub>TOTAL</sub>. Minima in the annual aboveground carbon increment of trees (C<sub>AI</sub>) occurred at sites during defoliation of aspen (<i>Populus tremuloides</i> Michx.) by forest tent caterpillar (<i>Malacosoma disstria</i> Hubner), and minima were more extreme at sites dominated by trembling aspen than sites mixed with conifers. At sites defoliated by forest tent caterpillar in the early 2000s, increased sequestration by the softwood component (<i>Abies balsamea</i> (L.) Mill. and <i>Picea glauca</i> (Moench) Voss) compensated for overall decreases in C<sub>AI</sub> by 17% on average. These results underscore the importance of accounting for low-severity canopy disturbance events when developing regional forest carbon models and argue for the restoration and maintenance of historically important conifer species within aspen mixedwoods to enhance stand-level resilience to disturbance agents and maintain site-level carbon stocks.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Forest Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"NRC Research Press, National Research Council Canada","publisherLocation":"Ottawa, Canada","doi":"10.1139/cjfr-2013-0165","usgsCitation":"Reinikainen, M., D’Amato, A.W., Bradford, J.B., and Fraver, S., 2014, Influence of stocking, site quality, stand age, low-severity canopy disturbance, and forest composition on sub-boreal aspen mixedwood carbon stocks: Canadian Journal of Forest Research, v. 44, no. 3, p. 230-242, https://doi.org/10.1139/cjfr-2013-0165.","productDescription":"13 p.","startPage":"230","endPage":"242","numberOfPages":"13","ipdsId":"IP-045433","costCenters":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"links":[{"id":282500,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282499,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/cjfr-2013-0165"}],"country":"United States","state":"Minnesota","otherGeospatial":"Laurentian Mixed Forest Province","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -97.24,43.5 ], [ -97.24,49.38 ], [ -89.48,49.38 ], [ -89.48,43.5 ], [ -97.24,43.5 ] ] ] } } ] }","volume":"44","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53517050e4b05569d805a2ee","contributors":{"authors":[{"text":"Reinikainen, Michael","contributorId":39286,"corporation":false,"usgs":true,"family":"Reinikainen","given":"Michael","email":"","affiliations":[],"preferred":false,"id":490559,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"D’Amato, Anthony W.","contributorId":35632,"corporation":false,"usgs":true,"family":"D’Amato","given":"Anthony","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":490558,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bradford, John B. 0000-0001-9257-6303 jbradford@usgs.gov","orcid":"https://orcid.org/0000-0001-9257-6303","contributorId":611,"corporation":false,"usgs":true,"family":"Bradford","given":"John","email":"jbradford@usgs.gov","middleInitial":"B.","affiliations":[{"id":568,"text":"Southwest Biological Science Center","active":true,"usgs":true}],"preferred":true,"id":490557,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fraver, Shawn","contributorId":91379,"corporation":false,"usgs":false,"family":"Fraver","given":"Shawn","email":"","affiliations":[{"id":7063,"text":"University of Maine","active":true,"usgs":false}],"preferred":false,"id":490560,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

An oral vaccine against plague has been developed for prairie dogs along with a palatable bait to deliver vaccine and a biomarker to track bait consumption. We conducted field trials between September 2009 and September 2012 to develop recommendations for bait distribution to deliver plague vaccine to prairie dogs. The objectives were to evaluate the use of the biomarker, rhodamine B, in field settings to compare bait distribution strategies, to compare uptake of baits distributed at different densities, to assess seasonal effects on bait uptake, and to measure bait uptake by nontarget small mammal species. Rhodamine B effectively marked prairie dogs' whiskers during these field trials. To compare bait distribution strategies, we applied baits around active burrows or along transects at densities of 32, 65, and 130 baits/ha. Distributing baits at active burrows or by transect did not affect uptake by prairie dogs. Distributing baits at rates of &ge;65/ha (or &ge;1 bait/active burrow) produced optimal uptake, and bait uptake by prairie dogs in the autumn was superior to uptake in the spring. Six other species of small mammals consumed baits during these trials. All four species of tested prairie dogs readily consumed the baits, demonstrating that vaccine uptake will not be an obstacle to plague control via oral vaccination.</p>","language":"English","publisher":"Wildlife Disease Association","doi":"10.7589/2013-04-100","usgsCitation":"Tripp, D.W., Rocke, T.E., Streich, S.P., Brown, N.L., Fernandez, J., and

The most common surveillance method for sylvatic plague is detection of antibodies to <i>Yersinia pestis</i> F1 capsular antigen in sentinel animals, such as coyotes (<i>Canis latrans</i>). Current serologic tests for <i>Y. pestis</i>, hemagglutination (HA) test and enzyme-linked immunosorbent assay (ELISA), are expensive and labor intensive. To address this need, we developed a complete lateral flow device for the detection of specific antibodies to <i>Y. pestis</i> F1 and V antigens. Our test detected anti-F1 and anti-V antibodies in serum and Nobuto filter paper samples from coyotes, and in serum samples from prairie dogs (<i>Cynomys ludovicianus</i>), lynx (<i>Lynx canadensis</i>), and black-footed ferrets (<i>Mustela nigripes</i>). Comparison of cassette results for anti-F1 and anti-V antibodies with results of ELISA or HA tests showed correlations ranging from 0.68 to 0.98. This device provides an affordable, user-friendly tool that may be useful in plague surveillance programs and as a research tool.</p>","language":"English","publisher":"Wildlife Disease

Nitrogen fractions in feces of herbivores include endogenous (e.g., sloughed \nintestinal cells, unresorbed digestive secretions, and microbial debris) and dietary sources. For animals such as large \nherbivores, that have diets and feces with high concentrations of indigestible fiber, endogenous <sup>15</sup>N may constrain the \nuse of fecal δ<sup>15</sup>N values to estimate dietary δ<sup>15</sup>N values and reconstruct diets.\n<br/>\nMETHODS: We compared two techniques (detergent and detergent-free) to isolate fractions of plant fibers in the forages \nof caribou (<i>Rangifer tarandus</i>) and muskoxen (<i>Ovibos moschatus</i>); estimated the discrimination factors between the δ<sup>15</sup>N \nvalues of fecal fiber residues and of the diets of captive animals; and used the more effective isotopic tracer of dietary \nδ<sup>15</sup>N values to examine the relationships between the δ<sup>15</sup>N values of fecal residues and diet composition in several \npopulations of wild caribou and muskoxen throughout North America in winter.\n<br/>\nRESULTS: The detergent-based approach contaminated the fractions of plant fibers in forages and feces with <sup>14</sup>N, whereas \nthe detergent-free method was a good proxy to estimate δ<sup>15</sup>N values of plant fibers (r<sup>2</sup>= 0.92) and provided a better estimate \nof the fecal-fiber to diet discrimination factor for both species (caribou = 3.6‰; muskoxen = 2.8‰). In wild populations, the \nδ<sup>15</sup>N values of fecal fibers reflected diet composition in muskoxen (adjusted R<sup>2</sup>= 0.43) but not caribou (adjusted R<sup>2</sup>= 0.06). \n<br/>\nCONCLUSIONS: Contamination from detergent residues prohibited the use of detergent extraction in isolating forage <sup>15</sup>N \nfrom endogenous <sup>15</sup>N in the feces of herbivores. Although δ<sup>15</sup>N values in fecal fibers can be used to track dietary δ<sup>15</sup>N values \nin wild herbivores, discrimination between fecal extracts and diet may vary with the contribution of endogenous nitrogen \n(N), and, therefore, residual endogenous <sup>15</sup>N in feces may limit dietary reconstructions from fecal δ<sup>15</sup>N values for some large \nherbivores.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Rapid Communications in Mass Spectrometry","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"John Wiley & Sons","publisherLocation":"New York, NY","doi":"10.1002/rcm.6825","usgsCitation":"Gustine, D.D., Barboza, P.S., Addison, J., Shively, R., and Oliver, L., 2014, Isotopic nitrogen in fecal fiber as an indicator of winter diet in caribou and muskoxen: Rapid Communications in Mass Spectrometry, v. 28, no. 6, p. 625-634, https://doi.org/10.1002/rcm.6825.","productDescription":"10 p.","startPage":"625","endPage":"634","numberOfPages":"10","ipdsId":"IP-051374","costCenters":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true}],"links":[{"id":282454,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/rcm.6825"},{"id":282457,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada;Greenland;United States","state":"Alaska","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -168.6,45.5 ], [ -168.6,79.9 ], [ -18.8,79.9 ], [ -18.8,45.5 ], [ -168.6,45.5 ] ] ] } } ] }","volume":"28","issue":"6","noUsgsAuthors":false,"publicationDate":"2014-02-05","publicationStatus":"PW","scienceBaseUri":"53517051e4b05569d805a2f6","contributors":{"authors":[{"text":"Gustine, David D. dgustine@usgs.gov","contributorId":3776,"corporation":false,"usgs":true,"family":"Gustine","given":"David","email":"dgustine@usgs.gov","middleInitial":"D.","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":490441,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barboza, Perry S.","contributorId":36454,"corporation":false,"usgs":false,"family":"Barboza","given":"Perry","email":"","middleInitial":"S.","affiliations":[{"id":13117,"text":"Institute of Arctic Biology, University of Alaska Fairbanks","active":true,"usgs":false}],"preferred":false,"id":490443,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Addison, Jennifer","contributorId":108396,"corporation":false,"usgs":true,"family":"Addison","given":"Jennifer","email":"","affiliations":[],"preferred":false,"id":490445,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shively, Rachel","contributorId":10718,"corporation":false,"usgs":true,"family":"Shively","given":"Rachel","email":"","affiliations":[],"preferred":false,"id":490442,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Oliver, Lola","contributorId":105223,"corporation":false,"usgs":true,"family":"Oliver","given":"Lola","email":"","affiliations":[],"preferred":false,"id":490444,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

Using high-resolution geospatial data and modeling, we construct probabilistic assessments of county-, state-, and national-level LUC and emissions for macroeconomic scenarios. We use the Cropland Data Layer and the Protected Areas Database to characterize availability of land for biofuel crop cultivation, and the CERES-Maize and BioCro biophysical crop growth models to estimate the suitability (yield potential) of available lands for biofuel crops. For LUC decisionmaking, we use a county-level stochastic partial-equilibrium modeling framework and consider five scenarios involving annual ethanol production scaling to 15, 22, and 29 BG, respectively, in 2022, with corn providing feedstock for the first 15 BG and the remainder coming from one of two dedicated energy crops. Finally, we derive high-resolution above-ground carbon factors from the National Biomass and Carbon Data set to estimate emissions from each LUC pathway. Based on these inputs, we obtain estimates for average total LUC emissions of 6.1, 2.2, 1.0, 2.2, and 2.4 gCO2e/MJ for Corn-15 Billion gallons (BG),&nbsp;</span><i>Miscanthus ×

The areas included the upper AOC as a reference area, the upper estuary, St. Louis Bay and Superior Bay. Grossly visible abnormalities were documented and preserved for microscopic analyses, as were five to eight representative pieces of liver tissue. A piece of dorsal muscle was preserved for stable isotope analyses and otoliths removed for age determination. The incidence of raised skin lesions (mucoid plaques) was high (31 %), however, microscopically only 4.5 % of the white suckers had neoplasia (papillomas). The remaining lesions were epidermal hyperplasia. Superior Bay had the lowest percentage of skin/lip lesions (10 %), while St. Louis Bay had the highest (44 %). St. Louis Bay also had the highest incidence of skin neoplasms (12 %). No hepatocellular neoplasms were documented, however bile duct tumors were observed in 4.5 % of the suckers. Foci of cellular alteration were observed in fish from all sites except the upper AOC. Stable isotope data indicated that most of the suckers relied on the St. Louis River AOC for the majority (>75 %) of their diet, indicating they were resident within the AOC and not in Lake Superior. The amount of diet obtained from the upper estuary was a significant predictor of skin lesion incidence. Hence, habitat use within the AOC appears to be an important risk factor for skin and possibly, liver lesions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecotoxicology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.1007/s10646-013-1167-5","usgsCitation":"Blazer, V., Hoffman, J., Walsh, H., Braham, R., Hahn, C., Collins, P., Jorgenson, Z., and Ledder, T., 2014, Health of white sucker within the St. Louis River area of concern associated with habitat usage as assessed using stable isotopes: Ecotoxicology, v. 23, no. 2, p. 236-251, https://doi.org/10.1007/s10646-013-1167-5.","productDescription":"15 p.","startPage":"236","endPage":"251","ipdsId":"IP-052117","costCenters":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"links":[{"id":473172,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s10646-013-1167-5","text":"Publisher Index Page"},{"id":282451,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282450,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s10646-013-1167-5"}],"country":"United States","state":"Minnesota;Wisconsin","otherGeospatial":"St. Louis River","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -92.465667,46.637474 ], [ -92.465667,46.760165 ], [ -92.000994,46.760165 ], [ -92.000994,46.637474 ], [ -92.465667,46.637474 ] ] ] } } ] }","volume":"23","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-12-27","publicationStatus":"PW","scienceBaseUri":"53033093e4b077b8e0dad962","contributors":{"authors":[{"text":"Blazer, V.
