C. Amanda Garcia, Jena M Huntington, Susan G. Buto, Michael T. Moreo, J. LaRue Smith, Brian J. Andraski
2014, Professional Paper 1805
With increasing population growth and land-use change, urban communities in the desert Southwest are progressively looking toward remote basins to supplement existing water supplies. Pending applications by Churchill County for groundwater appropriations from Dixie Valley, Nevada, a primarily undeveloped basin east of the Carson Desert, have prompted a reevaluation of...

Henry Lee II, Deborah A. Reusser, Melanie R Frazier, Lee M McCoy, Patrick J. Clinton, Jonathan S. Clough
2014, Report
Introduction Submerged aquatic vegetation (SAV) is an ecologically important habitat world‐wide. In Pacific Northwest (PNW) estuaries, SAV in the lower intertidal and shallow subtidal habitats are dominated by the native seagrass, Zostera marina Linnaeus, 1753. Within this report, SAV and seagrass refer to Z. marina seagrass beds in PNW estuaries. Z....

Robin E. Russell, Karl Tinsley, Richard A. Erickson, Wayne E. Thogmartin, Jennifer A. Szymanski
2014, Ecology and Evolution (4) 3746-3754
Depicting the spatial distribution of wildlife species is an important first step in developing management and conservation programs for particular species. Accurate representation of a species distribution is important for predicting the effects of climate change, land-use change, management activities, disease, and other landscape-level processes on wildlife populations. We developed...

Gary W. Page, Nils Warnock, T. Lee Tibbitts, Dennis Jorgensen, C. Alex Hartman, Lynne E. Stenzel
2014, The Condor (116) 50-61
Effective conservation of migratory species requires comprehensive knowledge of annual movement patterns. Such information is sparse for the Long-billed Curlew (Numenius americanus), a North American endemic shorebird of conservation concern. To test hypotheses about individual and area differences in migratory patterns across western North America, we tagged 29 curlews with...

Jessica Y. Adkins, Daniel D. Roby, Donald E. Lyons, Karen N. Courtot, Ken Collis, Harry R. Carter, W. David Shuford, Phillip J. Capitolo
2014, Journal of Wildlife Management (78) 1131-1142
The status of the double-crested cormorant (Phalacrocorax auritus) in western North America was last evaluated during 1987–2003. In the interim, concern has grown over the potential impact of predation by double-crested cormorants on juvenile salmonids (Oncorhynchusspp.), particularly in the Columbia Basin and along the Pacific coast where some salmonids are...
Disease and community structure: white-nose syndrome alters spatial and temporal niche partitioning in sympatric bat species
David S. Jachowski, Christopher A. Dobony, Laci S. Coleman, W. Mark Ford, Eric R. Britzke, Jane L. Rodrigue
2014, Diversity and Distributions (20) 1002-1015
AimEmerging infectious diseases present a major perturbation with apparent direct effects such as reduced population density, extirpation and/or extinction. Comparatively less is known about the potential indirect effects of disease that likely alter community structure and larger ecosystem function. Since 2006, white-nose syndrome (WNS) has resulted in the loss of...

Paul A. Bedrosian, Daniel W. Feucht
2014, Earth and Planetary Science Letters (402) 275-289
The magnetotelluric component of the EarthScope USArray program has covered over 35% of the continental United States. Resistivity tomography models derived from these data image lithospheric structure and provide constraints on the distribution of fluids and melt within the lithosphere. We present a three-dimensional resistivity model of the northwestern United...
