Both increased corn growth for ethanol production and perennial dedicated energy crop growth for cellulosic feedstocks are potential sources to meet the rising demand for biofuels. However, these measures may cause adverse environmental consequences that are not yet fully understood. This study 1) evaluates the long-term impacts of increased frequency of corn in the crop rotation system on water quantity and quality as well as soil fertility in the James River Basin and 2) identifies potential grasslands for cultivating bioenergy crops (e.g. switchgrass), estimating the water quality impacts. We selected the soil and water assessment tool, a physically based multidisciplinary model, as the modeling approach to simulate a series of biofuel production scenarios involving crop rotation and land cover changes. The model simulations with different crop rotation scenarios indicate that decreases in water yield and soil nitrate nitrogen (NO<sub>3</sub>-N) concentration along with an increase in NO<sub>3</sub>-N load to stream water could justify serious concerns regarding increased corn rotations in this basin. Simulations with land cover change scenarios helped us spatially classify the grasslands in terms of biomass productivity and nitrogen loads, and we further derived the relationship of biomass production targets and the resulting nitrogen loads against switchgrass planting acreages. The suggested economically efficient (planting acreage) and environmentally friendly (water quality) planting locations and acreages can be a valuable guide for cultivating switchgrass in this basin. This information, along with the projected environmental costs (i.e. reduced water yield and increased nitrogen load), can contribute to decision support tools for land managers to seek the sustainability of biofuel development in this region.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"GCB Bioenergy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1111/j.1757-1707.2012.01164.x","usgsCitation":"Wu, Y., Liu, S., and Li, Z., 2012, Identifying potential areas for biofuel production and evaluating the environmental effects: a case study of the James River Basin in the Midwestern United States: GCB Bioenergy, v. 4, no. 6, p. 875-888, https://doi.org/10.1111/j.1757-1707.2012.01164.x.","productDescription":"14 p.","startPage":"875","endPage":"888","ipdsId":"IP-033265","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":474133,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1757-1707.2012.01164.x","text":"Publisher Index Page"},{"id":273334,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":273333,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1757-1707.2012.01164.x"}],"country":"United States","state":"Missouri","otherGeospatial":"James River Basin","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -95.7747,35.9957 ], [ -95.7747,40.6136 ], [ -89.0995,40.6136 ], [ -89.0995,35.9957 ], [ -95.7747,35.9957 ] ] ] } } ] }","volume":"4","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-02-27","publicationStatus":"PW","scienceBaseUri":"51b05de6e4b030b51980122f","contributors":{"authors":[{"text":"Wu, Yiping ywu@usgs.gov","contributorId":987,"corporation":false,"usgs":true,"family":"Wu","given":"Yiping","email":"ywu@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":true,"id":473496,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Liu, Shu-Guang sliu@usgs.gov","contributorId":984,"corporation":false,"usgs":true,"family":"Liu","given":"Shu-Guang","email":"sliu@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":false,"id":473495,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Li, Zhengpeng","contributorId":80812,"corporation":false,"usgs":true,"family":"Li","given":"Zhengpeng","affiliations":[],"preferred":false,"id":473497,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

These developments include identifying vulnerable building types in any given area, estimating earthquake-induced damage and loss statistics by building type, and developing visualization aids that help locate areas of concern for improving post-earthquake response efforts. While detailed exposure and damage information is highly useful and desirable, significant improvements are still necessary in order to improve underlying building stock and vulnerability data at a global scale. Existing efforts with the GEM’s GED4GEM and GVC consortia will help achieve some of these objectives. This will benefit PAGER especially in regions where PAGER’s empirical model is less-well constrained; there, the semi-empirical and analytical models will provide robust estimates of damage and losses.

However, thousands of sand dunes spread across 12,000 km<sup>2</sup> in eastern upper Michigan (EUM), more than 500 km east of the present forest-prairie ecotone, present a challenge to such models. We use 65 optically stimulated luminescence (OSL) ages on quartz sand deposited in silt caps (n = 8) and dunes (n = 57) to document eolian activity in EUM. Dune building was widespread ca. 10–8 ka, indicating a sharp, sustained decline in forest cover during that period. This decline was roughly coincident with hydrologic closure of the upper Great Lakes, but temporally inconsistent with most pollen-based models that imply canopy closure throughout the Holocene. Early Holocene forest openings are rarely recognized in pollen sums from EUM because faint signatures of non-arboreal pollen are largely obscured by abundant and highly mobile pine pollen. Early Holocene spikes in nonarboreal pollen are recorded in cores from small ponds, but suggest only a modest extent of forest openings. OSL dating of dune emplacement provides a direct, spatially explicit archive of greatly diminished forest cover during a very dry climate in eastern midcontinent North America ca. 10–8 ka.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"GSA","doi":"10.1130/G32937.1","usgsCitation":"Loope, W.L., Loope, H.M., Goble, R.J., Fisher, T.G., Lytle, D.E., Legg, R.J., Wysocki, D., Hanson, P.R., and Young, A., 2012, Drought drove forest decline and dune building in eastern upper Michigan, USA, as the upper Great Lakes became closed basins: Geology, v. 40, no. 4, p. 315-318, https://doi.org/10.1130/G32937.1.","productDescription":"4 p.","startPage":"315","endPage":"318","ipdsId":"IP-028146","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":271774,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":271773,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/G32937.1"}],"otherGeospatial":"North America","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 177.1,5.6 ], [ 177.1,85.4 ], [ -4.0,85.4 ], [ -4.0,5.6 ], [ 177.1,5.6 ] ] ] } } ] }","volume":"40","issue":"4","noUsgsAuthors":false,"publicationDate":"2012-02-28","publicationStatus":"PW","scienceBaseUri":"51838ae8e4b0a21483941a9d","contributors":{"authors":[{"text":"Loope, Walter L. wloope@usgs.gov","contributorId":4616,"corporation":false,"usgs":true,"family":"Loope","given":"Walter","email":"wloope@usgs.gov","middleInitial":"L.","affiliations":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"preferred":true,"id":474439,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Loope, Henry M.","contributorId":79381,"corporation":false,"usgs":true,"family":"Loope","given":"Henry","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":474446,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Goble, Ronald J.","contributorId":61319,"corporation":false,"usgs":true,"family":"Goble","given":"Ronald","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":474444,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Fisher, Timothy G.","contributorId":45659,"corporation":false,"usgs":true,"family":"Fisher","given":"Timothy","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":474443,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Lytle, David E. dlytle@usgs.gov","contributorId":343,"corporation":false,"usgs":true,"family":"Lytle","given":"David","email":"dlytle@usgs.gov","middleInitial":"E.","affiliations":[],"preferred":true,"id":474438,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Legg, Robert J.","contributorId":30527,"corporation":false,"usgs":true,"family":"Legg","given":"Robert","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":474441,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Wysocki, Douglas A.","contributorId":61320,"corporation":false,"usgs":true,"family":"Wysocki","given":"Douglas A.","affiliations":[],"preferred":false,"id":474445,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Hanson, Paul R.","contributorId":35214,"corporation":false,"usgs":true,"family":"Hanson","given":"Paul","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":474442,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Young, Aaron R.","contributorId":12353,"corporation":false,"usgs":true,"family":"Young","given":"Aaron R.","affiliations":[],"preferred":false,"id":474440,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

One of the challenges to understanding the toxic effects of nonylphenols is the large number of isomers that may exist in environmental samples. In order to attribute toxic effects to specific compounds, a method is needed for the separation and quantitation of individual nonylphenol isomers. The pre-concentration methods of solvent sublimation, solid-phase extraction or liquid–liquid extraction prior to chromatographic analysis can be problematic because of co-extraction of thousands of compounds typically found in complex matrices such as municipal wastewater or landfill leachate. In the present study, steam distillation extraction (SDE) was found to be an effective pre-concentration method for extraction of 4-NPs from leachate and wastewater, and comprehensive two-dimensional gas chromatography (GC × GC) coupled with fast mass spectral data acquisition by time-of-flight mass spectrometry (ToFMS) enhanced the resolution and identification of 4-NP isomers. Concentrations of eight 4-NP isomers were determined in leachate from landfill cells of different age and wastewater influent and effluent samples. 4-NP isomers were about 3 times more abundant in leachate from the younger cell than the older one, whereas concentrations in wastewater effluent were either below detection limits or <1% of influent concentrations. 4-NP isomer distribution patterns were found to have been altered following release to the environment. This is believed to reflect isomer-specific degradation and accumulation of 4-NPs in the aquatic environment.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Chromatography A","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.chroma.2011.12.109","usgsCitation":"Zhang, C., Eganhouse, R., Pontolillo, J., Cozzarelli, I.M., and Wang, Y., 2012, Determination of nonylphenol isomers in landfill leachate and municipal wastewater using steam distillation extraction coupled with comprehensive two-dimensional gas chromatography/time-of-flight mass spectrometry: Journal of Chromatography A, v. 1230, p. 110-116, https://doi.org/10.1016/j.chroma.2011.12.109.","productDescription":"7 p.","startPage":"110","endPage":"116","ipdsId":"IP-030281","costCenters":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"links":[{"id":271420,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":268627,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.chroma.2011.12.109"}],"volume":"1230","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5178fee3e4b0d842c705f6d7","contributors":{"authors":[{"text":"Zhang, Caixiang","contributorId":61321,"corporation":false,"usgs":true,"family":"Zhang","given":"Caixiang","email":"","affiliations":[],"preferred":false,"id":475244,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Eganhouse, Robert P. eganhous@usgs.gov","contributorId":2031,"corporation":false,"usgs":true,"family":"Eganhouse","given":"Robert P.","email":"eganhous@usgs.gov","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":475242,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Pontolillo, James jpontoli@usgs.gov","contributorId":2033,"corporation":false,"usgs":true,"family":"Pontolillo","given":"James","email":"jpontoli@usgs.gov","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":475243,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Cozzarelli, Isabelle M. 0000-0002-5123-1007 icozzare@usgs.gov","orcid":"https://orcid.org/0000-0002-5123-1007","contributorId":1693,"corporation":false,"usgs":true,"family":"Cozzarelli","given":"Isabelle","email":"icozzare@usgs.gov","middleInitial":"M.","affiliations":[{"id":49175,"text":"Geology, Energy & Minerals Science Center","active":true,"usgs":true},{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":475241,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Wang, Yanxin","contributorId":81389,"corporation":false,"usgs":true,"family":"Wang","given":"Yanxin","email":"","affiliations":[],"preferred":false,"id":475245,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The precise impacts will, however, strongly depend on socioeconomic conditions such as local markets and food import dependence. In the near term, two factors are also changing the nature of food security: (1) rapid urbanization, with the proportion of the global population living in urban areas expanding from 13 percent in 1975 to greater than 50 percent at present, and (2) trade and domestic market liberalization since 1993, which has promoted removal of import controls, deregulation of prices, and the loss of preferential markets for many small economies.\n\nOver the last two years, the worst drought in decades has devastated eastern Africa. The resulting food-security crisis has affected roughly 13 million people and has reminded us that there is still a long way to go in addressing current climate-related risks. In the face of such profound changes and uncertainties, our approaches to food security must evolve. In this article, we describe four key elements that, in our view, will be essential to the success of efforts to address the linked challenges of food security and climate change.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Solutions Journal","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Solutions","usgsCitation":"Pulwarty, R., Eilerts, G., and Verdin, J., 2012, Food security in a changing climate: Solutions Journal, v. 3, no. 1, p. 31-34.","productDescription":"4 p.","startPage":"31","endPage":"34","ipdsId":"IP-037246","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":272781,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":272780,"type":{"id":15,"text":"Index Page"},"url":"https://www.thesolutionsjournal.com/node/1054"}],"volume":"3","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51a08be0e4b0e4245580656e","contributors":{"authors":[{"text":"Pulwarty, Roger","contributorId":28149,"corporation":false,"usgs":true,"family":"Pulwarty","given":"Roger","affiliations":[],"preferred":false,"id":473333,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Eilerts, Gary","contributorId":31101,"corporation":false,"usgs":true,"family":"Eilerts","given":"Gary","email":"","affiliations":[],"preferred":false,"id":473334,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Verdin, James 0000-0003-0238-9657","orcid":"https://orcid.org/0000-0003-0238-9657","contributorId":99647,"corporation":false,"usgs":true,"family":"Verdin","given":"James","affiliations":[],"preferred":false,"id":473335,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

If this improved assessment yields a net social benefit, then that benefit reflects the value of information (VOI) from MRLI. Environmental quality and the capacity to provide ecosystem services evolve because of human actions, changing natural conditions, and their interaction with natural physical processes. The human actions, in turn, are constrained and redirected by many institutions and regulations such as agricultural, energy, and environmental policies. We present a general framework for bringing together sociologic, biologic, physical, hydrologic, and geologic processes at meaningful scales to interpret environmental implications of MRLI applications. We set out a specific application using MRLI observations to identify crop planting patterns and thus estimate surface management activities that influence groundwater resources over a regional landscape. We tailor the application to the characteristics of nonpoint source groundwater pollution hazards in Iowa to illustrate a general framework in a land use-hydrologic-economic system. In the example, MRLI VOI derives from reducing the risk of both losses to agricultural production and damage to human health and other consequences of contaminated groundwater.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"The value of information","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Springer","publisherLocation":"Amsterdam, Netherlands","doi":"10.1007/978-94-007-4839-2_10","collaboration":"This is Chapter 10","usgsCitation":"Bernknopf, R.L., Forney, W.M., Raunikar, R.P., and Mishra, S.K., 2012, Estimating the benefits of land imagery in environmental applications: a case study in nonpoint source pollution of groundwater, chap. <i>of</i> The value of information, p. 257-299, https://doi.org/10.1007/978-94-007-4839-2_10.","productDescription":"43 p.","startPage":"257","endPage":"299","ipdsId":"IP-024922","costCenters":[{"id":657,"text":"Western Geographic Science Center","active":true,"usgs":true}],"links":[{"id":269684,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269683,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/978-94-007-4839-2_10"}],"noUsgsAuthors":false,"publicationDate":"2012-07-03","publicationStatus":"PW","scienceBaseUri":"51483788e4b022dd171afe59","contributors":{"editors":[{"text":"Laxminarayan, Ramanan","contributorId":112226,"corporation":false,"usgs":true,"family":"Laxminarayan","given":"Ramanan","email":"","affiliations":[],"preferred":false,"id":508223,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Maccauley, Molly K.","contributorId":112432,"corporation":false,"usgs":true,"family":"Maccauley","given":"Molly","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":508224,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Bernknopf, Richard L.","contributorId":97061,"corporation":false,"usgs":true,"family":"Bernknopf","given":"Richard","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":350426,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Forney, William M.","contributorId":43490,"corporation":false,"usgs":true,"family":"Forney","given":"William","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":350425,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Raunikar, Ronald P.","contributorId":101535,"corporation":false,"usgs":true,"family":"Raunikar","given":"Ronald","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":350427,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Mishra, Shruti K.","contributorId":21432,"corporation":false,"usgs":true,"family":"Mishra","given":"Shruti","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":350424,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Many salmonids are in need of such efforts, and because they often persist in differing, isolated environments, they are useful organisms for studying local adaptation. In addition, the temperature sensitivity of salmonids provides a likely target for natural selection. We studied thermal adaptation in four wild populations and one hatchery stock of westslope cutthroat trout Oncorhynchus clarkii lewisi . The mean summer temperatures of source streams ranged from 6.7°C to 11.2°C. Embryos were collected from the wild, and embryonic development, embryonic survival, and juvenile growth were determined. A significant relationship between median embryonic survival and source stream temperature was detected. Based on a rank test, populations from colder streams had a greater decline in median embryonic survival at warm temperatures than populations from warmer streams. Embryonic development and juvenile growth did not appear to be influenced by source. These findings suggest that populations are thermally adapted to their source streams and this should be considered by managers. However, further study is necessary to sort out the potential confounding factors, whether genetic or epigenetic.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Transactions of the American Fisheries Society","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Taylor & Francis","publisherLocation":"Philadelphia, PA","doi":"10.1080/00028487.2012.675907","usgsCitation":"Drinan, D.P., Zale, A.V., Webb, M.A., Taper, M.L., Shepard, B.B., and Kalinowski, S.T., 2012, Evidence of local adaptation in westslope cutthroat trout: Transactions of the American Fisheries Society, v. 141, no. 4, p. 872-880, https://doi.org/10.1080/00028487.2012.675907.","productDescription":"9 p.","startPage":"872","endPage":"880","ipdsId":"IP-029234","costCenters":[{"id":398,"text":"Montana Cooperative Fishery Research Unit","active":false,"usgs":true}],"links":[{"id":269985,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269984,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1080/00028487.2012.675907"}],"volume":"141","issue":"4","noUsgsAuthors":false,"publicationDate":"2012-06-11","publicationStatus":"PW","scienceBaseUri":"515171ede4b087909f0bbe9c","contributors":{"authors":[{"text":"Drinan, Daniel P.","contributorId":37614,"corporation":false,"usgs":true,"family":"Drinan","given":"Daniel","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":349077,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Zale, Alexander V. 0000-0003-1703-885X zale@usgs.gov","orcid":"https://orcid.org/0000-0003-1703-885X","contributorId":3010,"corporation":false,"usgs":true,"family":"Zale","given":"Alexander","email":"zale@usgs.gov","middleInitial":"V.","affiliations":[{"id":200,"text":"Coop Res Unit Seattle","active":true,"usgs":true}],"preferred":true,"id":349076,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Webb, Molly A.H.","contributorId":64121,"corporation":false,"usgs":true,"family":"Webb","given":"Molly","email":"","middleInitial":"A.H.","affiliations":[],"preferred":false,"id":349079,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Taper, Mark L.","contributorId":105192,"corporation":false,"usgs":true,"family":"Taper","given":"Mark","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":349081,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Shepard, Bradley B.","contributorId":57327,"corporation":false,"usgs":true,"family":"Shepard","given":"Bradley","email":"","middleInitial":"B.","affiliations":[],"preferred":false,"id":349078,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Kalinowski, Steven T.","contributorId":78465,"corporation":false,"usgs":true,"family":"Kalinowski","given":"Steven","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":349080,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Understanding population genetic structure within a continuous population can give insights into social structure, movement across the landscape and contact between populations, which influence ecological interactions, reproductive dynamics or pathogen transmission. We investigated the genetic structure of a large population of deer spanning the area of Wisconsin and Illinois, USA, affected by chronic wasting disease. We combined multiscale investigation, landscape genetic techniques and spatial statistical modelling to address the complex questions of landscape factors influencing population structure. We sampled over 2000 deer and used spatial autocorrelation and a spatial principal components analysis to describe the population genetic structure. We evaluated landscape effects on this pattern using a spatial autoregressive model within a model selection framework to test alternative hypotheses about gene flow. We found high levels of genetic connectivity, with gradients of variation across the large continuous population of white-tailed deer. At the fine scale, spatial clustering of related animals was correlated with the amount and arrangement of forested habitat. At the broader scale, impediments to dispersal were important to shaping genetic connectivity within the population. We found significant barrier effects of individual state and interstate highways and rivers. Our results offer an important understanding of deer biology and movement that will help inform the management of this species in an area where overabundance and disease spread are primary concerns.</span></p>","language":"English","publisher":"Wiley","doi":"10.1111/j.1365-294X.2012.05681.x","usgsCitation":"Robinson, S.J., Samuel, M.D., Lopez, D.L., and Shelton, P., 2012, The walk is never random: subtle landscape effects shape gene flow in a continuous white-tailed deer population in the Midwestern United States: Molecular Ecology, v. 21, no. 17, p. 4190-4205, https://doi.org/10.1111/j.1365-294X.2012.05681.x.","productDescription":"16 p.","startPage":"4190","endPage":"4205","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-035189","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":323760,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Illinois, Wisconsin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -90.977783203125,\n              41.918628865183045\n            ],\n            [\n              -90.977783203125,\n              43.731414013769\n            ],\n            [\n              -87.7642822265625,\n              43.731414013769\n            ],\n            [\n              -87.7642822265625,\n              41.918628865183045\n            ],\n            [\n              -90.977783203125,\n              41.918628865183045\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"21","issue":"17","publishingServiceCenter":{"id":9,"text":"Reston PSC"},"noUsgsAuthors":false,"publicationDate":"2012-08-07","publicationStatus":"PW","scienceBaseUri":"5763cdbae4b07657d19ba79a","contributors":{"authors":[{"text":"Robinson, Stacie J.","contributorId":172022,"corporation":false,"usgs":false,"family":"Robinson","given":"Stacie","email":"","middleInitial":"J.","affiliations":[{"id":12508,"text":"Department of Forest and Wildlife Ecology, University of Wisconsin, 1710 University Ave., Room 285, Madison, WI 53726, USA","active":true,"usgs":false}],"preferred":false,"id":637243,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Samuel, Michael D. msamuel@usgs.gov","contributorId":1419,"corporation":false,"usgs":true,"family":"Samuel","given":"Michael","email":"msamuel@usgs.gov","middleInitial":"D.","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"preferred":true,"id":637240,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Lopez, Davin L.","contributorId":171378,"corporation":false,"usgs":false,"family":"Lopez","given":"Davin","email":"","middleInitial":"L.","affiliations":[{"id":7242,"text":"Wisconsin Department of Natural Resources, Madison, WI, USA","active":true,"usgs":false}],"preferred":false,"id":637241,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Shelton, Paul","contributorId":171375,"corporation":false,"usgs":false,"family":"Shelton","given":"Paul","email":"","affiliations":[{"id":26879,"text":"Illinois DNR, Springfield, IL","active":true,"usgs":false}],"preferred":false,"id":637242,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

We use literature review, synthesis and model simulations to explore the role of mosses in ecological stability and resilience. Moss community responses to disturbance showed all possible responses (increases, decreases, no change) within most disturbance categories. Simulations from two process-based models suggest that northern ecosystems would need to experience extreme perturbation before mosses were eliminated. But simulations with two other models suggest that loss of moss will reduce soil carbon accumulation primarily by influencing decomposition rates and soil nitrogen availability. It seems clear that mosses need to be incorporated into models as one or more plant functional types, but more empirical work is needed to determine how to best aggregate species. We highlight several issues that have not been adequately explored in moss communities, such as functional redundancy and singularity, relationships between response and effect traits, and parameter vs conceptual uncertainty in models. Mosses play an important role in several ecosystem processes that play out over centuries – permafrost formation and thaw, peat accumulation, development of microtopography – and there is a need for studies that increase our understanding of slow, long-term dynamical processes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"New Phytologist","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","publisherLocation":"Hoboken, NJ","doi":"10.1111/j.1469-8137.2012.04254.x","usgsCitation":"Turetsky, M., Bond-Lamberty, B., Euskirchen, E., Talbot, J.J., Frolking, S., McGuire, A., and Tuittila, E., 2012, The resilience and functional role of moss in boreal and arctic ecosystems: New Phytologist, v. 196, no. 1, p. 49-67, https://doi.org/10.1111/j.1469-8137.2012.04254.x.","productDescription":"19 p.","startPage":"49","endPage":"67","ipdsId":"IP-037711","costCenters":[{"id":108,"text":"Alaska Cooperative Fish and Wildlife Research Unit","active":false,"usgs":true}],"links":[{"id":474167,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1111/j.1469-8137.2012.04254.x","text":"Publisher Index Page"},{"id":269278,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1469-8137.2012.04254.x"},{"id":269279,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"196","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-08-24","publicationStatus":"PW","scienceBaseUri":"5141a016e4b0eefcba208e3a","contributors":{"authors":[{"text":"Turetsky, M.","contributorId":108302,"corporation":false,"usgs":true,"family":"Turetsky","given":"M.","affiliations":[],"preferred":false,"id":471214,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bond-Lamberty, B.","contributorId":74269,"corporation":false,"usgs":true,"family":"Bond-Lamberty","given":"B.","affiliations":[],"preferred":false,"id":471212,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Euskirchen, E.S.","contributorId":44737,"corporation":false,"usgs":true,"family":"Euskirchen","given":"E.S.","affiliations":[],"preferred":false,"id":471210,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Talbot, J.

We present a prototype gravity-fed splitter apparatus for dividing large samples of small fish (30–100 mm TL). The apparatus features a tapered hopper with a sliding and removable shutter. The apparatus provides a comparatively stable platform for objectively obtaining subsamples, and it can be modified to accommodate different sizes of fish and different sample volumes. The apparatus is easy to build, inexpensive, and convenient to use in the field. To illustrate the performance of the apparatus, we divided three samples (total <i>N</i> = 2,000 fish) composed of four fish species. Our results indicated no significant bias in estimating either the number or proportion of each species from the subsample. Use of this apparatus or a similar apparatus can help to standardize subsampling procedures in large surveys of fish.

Given the importance of secondary aftershock triggering in sequences of large events, a concern is whether this cluster of events could trigger another damaging earthquake near Paso Robles. An epidemic‐type aftershock sequence (ETAS) model is fit to the Rinconada seismicity, and multiple realizations indicate a 0.36% probability of at least one M≥6.0 earthquake during the next 30 years. However, this probability estimate is only as good as the projection into the future of the ETAS model. There is evidence that the seismicity may be influenced by fluid pressure changes, which cannot be forecasted using ETAS. The strongest evidence for fluids is the delay between the San Simeon mainshock and a high rate of seismicity in mid to late 2004. This delay can be explained as having been caused by a pore pressure decrease due to an undrained response to the coseismic dilatation, followed by increased pore pressure during the return to equilibrium. Seismicity migration along the fault also suggests fluid involvement, although the migration is too slow to be consistent with pore pressure diffusion. All other evidence, including focal mechanisms and b‐value, is consistent with tectonic earthquakes. This suggests a model where the role of fluid pressure changes is limited to the first seven months, while the fluid pressure equilibrates. The ETAS modeling adequately fits the events after July 2004 when the pore pressure stabilizes. The ETAS models imply that while the probability of a damaging earthquake on the Rinconada fault has approximately doubled due to the San Simeon earthquake, the absolute probability remains low.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of the Seismological Society of America","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Seismological Society of America","publisherLocation":"El Cerrito, CA","doi":"10.1785/0120110169","usgsCitation":"Hardebeck, J.L., 2012, Fluid‐driven seismicity response of the Rinconada fault near Paso Robles, California, to the 2003 M 6.5 San Simeon earthquake: Bulletin of the Seismological Society of America, v. 102, no. 1, p. 377-390, https://doi.org/10.1785/0120110169.","productDescription":"14 p.","startPage":"377","endPage":"390","ipdsId":"IP-030353","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":269280,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1785/0120110169"},{"id":269281,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.4,32.5 ], [ -124.4,42.0 ], [ -114.1,42.0 ], [ -114.1,32.5 ], [ -124.4,32.5 ] ] ] } } ] }","volume":"102","issue":"1","noUsgsAuthors":false,"publicationDate":"2012-02-15","publicationStatus":"PW","scienceBaseUri":"51419ff9e4b0eefcba208d9a","contributors":{"authors":[{"text":"Hardebeck, Jeanne L. 0000-0002-6737-7780 jhardebeck@usgs.gov","orcid":"https://orcid.org/0000-0002-6737-7780","contributorId":841,"corporation":false,"usgs":true,"family":"Hardebeck","given":"Jeanne","email":"jhardebeck@usgs.gov","middleInitial":"L.","affiliations":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":234,"text":"Earthquake Hazards Program","active":true,"usgs":true}],"preferred":true,"id":471216,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We further evaluated this by relating the quantity of prey found in fish diets to the quantity of prey available to fish, providing insight into feeding behavior and prey preferences. We describe the seasonal prey selection of major fish species collected across 18 stations in Lake Superior in spring, summer, and fall of 2005. Of the major nearshore fish species, bloater (<i>Coregonus hoyi</i>), rainbow smelt (<i>Osmerus mordax</i>), and lake whitefish (<i>Coregonus clupeaformis</i>) consumed <i>Mysis</i>, and strongly selected <i>Mysis</i> over other prey items each season. However, lake whitefish also selected <i>Bythotrephes</i> in the fall when <i>Bythotrephes</i> were numerous. Cisco (<i>Coregonus artedi</i>), a major nearshore and offshore species, fed largely on calanoid copepods, and selected calanoid copepods (spring) and <i>Bythotrephes</i> (summer and fall). Cisco also targeted prey similarly across bathymetric depths. Other major offshore fish species such as kiyi (<i>Coregonus kiyi</i>) and deepwater sculpin (<i>Myoxocephalus thompsoni</i>) fed largely on <i>Mysis</i>, with kiyi targeting <i>Mysis</i> exclusively while deepwater sculpin did not prefer any single prey organism. The major offshore predator siscowet lake trout (<i>Salvelinus namaycush siscowet</i>) consumed deepwater sculpin and coregonines, but selected deepwater sculpin and <i>Mysis</i> each season, with juveniles having a higher selection for <i>Mysis</i> than adults. Our results suggest that <i>Mysis</i> is not only a commonly consumed prey item, but a highly preferred prey item for pelagic, benthic, and piscivorous fishes in nearshore and offshore waters of Lake Superior.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Great Lakes Research","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","publisherLocation":"Amsterdam, Netherlands","doi":"10.1016/j.jglr.2012.02.017","usgsCitation":"Isaac, E.J., Hrabik, T.R., Stockwell, J.D., and Gamble, A.E., 2012, Prey selection by the Lake Superior fish community: Journal of Great Lakes Research, v. 38, no. 2, p. 326-335, https://doi.org/10.1016/j.jglr.2012.02.017.","productDescription":"10 p.","startPage":"326","endPage":"335","ipdsId":"IP-035901","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":268719,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.jglr.2012.02.017"},{"id":268720,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Lake Superior","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -92.5,46.25 ], [ -92.5,49.0 ], [ -84.33,49.0 ], [ -84.33,46.25 ], [ -92.5,46.25 ] ] ] } } ] }","volume":"38","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5135d092e4b03b8ec4025bad","contributors":{"authors":[{"text":"Isaac, Edmund J.","contributorId":64120,"corporation":false,"usgs":true,"family":"Isaac","given":"Edmund","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":470542,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hrabik, Thomas R.","contributorId":35614,"corporation":false,"usgs":false,"family":"Hrabik","given":"Thomas","email":"","middleInitial":"R.","affiliations":[{"id":6915,"text":"University of Minnesota - Duluth","active":true,"usgs":false}],"preferred":false,"id":470539,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Stockwell, Jason D. 0000-0003-3393-6799","orcid":"https://orcid.org/0000-0003-3393-6799","contributorId":61004,"corporation":false,"usgs":false,"family":"Stockwell","given":"Jason","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":470541,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Gamble, Allison E.","contributorId":56940,"corporation":false,"usgs":true,"family":"Gamble","given":"Allison","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":470540,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Nonetheless, these records prompted this study of the response of the bridge to low amplitude shaking caused by three earthquakes. Compared to previous ambient vibration studies, the earthquake response data reveal a slightly higher fundamental frequency (shorter-period) for vertical vibration of the bridge deck center span (~7.7–8.3 s versus 8.2–10.6 s), and a much higher fundamental frequency (shorter period) for the transverse direction of the deck (~11.24–16.3 s versus ~18.2 s).

In contrast, spermiated male washings induced upstream movement, prolonged retention on a nest and induced an array of nesting behaviours.

We examined bird species richness, community density and community evenness in forests of eastern Connecticut to determine whether: 1) spatial and seasonal patterns exist in diversity, 2) energy explains the greatest proportion of variation in diversity parameters, 3) variation in habitat explains remaining diversity variance, and 4) seasonal shifts in diversity provide clues about how environmental variables shape communities. We sought to discover if our data supported predictions of the species–energy hypothesis. We used the variable circular plot technique to estimate bird populations and quantified the location, elevation, forest type, vegetation type, canopy cover, moisture regime, understory density and primary production for the study sites. We found that 1) summer richness and population densities are roughly equal in northeastern and southeastern Connecticut, whereas in winter both concentrate toward the coast, 2) variables linked with temperature explained much of the patterns in winter diversity, but energy-related variables showed little relationship to summer diversity, 3) the effect of habitat variables on diversity parameters predominated in summer, although their effect was weak, 4) contrary to theory, evenness increased from summer to winter, and 5) support for predictions of species–energy theory was primarily restricted to winter data. Although energy and habitat played a role in explaining community patterns, they left much of the variance in regional diversity unexplained, suggesting that a large stochastic component to diversity also may exist.","language":"English","publisher":"Wiley","doi":"10.1111/j.1600-0587.2012.07790.x","usgsCitation":"Craig, R., and Klaver, R.W., 2012, Factors influencing geographic patterns in diversity of forest bird communities of eastern Connecticut, USA: Ecography, v. 36, no. 5, p. 599-609, https://doi.org/10.1111/j.1600-0587.2012.07790.x.","productDescription":"11 p.","startPage":"599","endPage":"609","ipdsId":"IP-021424","costCenters":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true}],"links":[{"id":474272,"rank":2,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://lib.dr.iastate.edu/nrem_pubs/213","text":"Publisher Index Page"},{"id":274137,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Connecticut","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -73.73,40.99 ], [ -73.73,42.05 ], [ -71.79,42.05 ], [ -71.79,40.99 ], [ -73.73,40.99 ] ] ] } } ] }","volume":"36","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51cabbe0e4b0d298e5434c34","contributors":{"authors":[{"text":"Craig, Robert J.","contributorId":79781,"corporation":false,"usgs":true,"family":"Craig","given":"Robert J.","affiliations":[],"preferred":false,"id":349660,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Klaver, Robert W. 0000-0002-3263-9701 bklaver@usgs.gov","orcid":"https://orcid.org/0000-0002-3263-9701","contributorId":3285,"corporation":false,"usgs":true,"family":"Klaver","given":"Robert","email":"bklaver@usgs.gov","middleInitial":"W.","affiliations":[{"id":199,"text":"Coop Res Unit Leetown","active":true,"usgs":true},{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"preferred":true,"id":349659,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
