Kristin McDougall, Debra L. Block
2014, Scientific Investigations Report 2014-5120
The eastern San Francisco Bay region (Contra Costa and Alameda Counties, California) is a geologically complex area divided by faults into a suite of tectonic blocks. Each block contains a unique stratigraphic sequence of Tertiary sediments that in most blocks unconformably overlie Mesozoic sediments. Age and environmental interpretations based on...
Sea Level Affecting Marshes Model (SLAMM) ‐ New functionality for predicting changes in distribution of submerged aquatic vegetation in response to sea level rise
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....

Gregory J. Walsh
2014, Scientific Investigations Map 3295
The bedrock geology of the 7.5-minute Uxbridge quadrangle consists of Neoproterozoic metamorphic and igneous rocks of the Avalon zone. In this area, rocks of the Avalon zone lie within the core of the Milford antiform, south and east of the terrane-bounding Bloody Bluff fault zone. Permian pegmatite dikes and quartz...
Estimating the spatial distribution of wintering little brown bat populations in the eastern United States
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...
Annual migratory patterns of long-billed curlews in the American west
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...

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...

Stephanie J. Perles, Tyler Wagner, Brian J. Irwin, Douglas R. Manning, Kristina K. Callahan, Matthew R. Marshall
2014, Environmental Management (54) 641-655
Forests are socioeconomically and ecologically important ecosystems that are exposed to a variety of natural and anthropogenic stressors. As such, monitoring forest condition and detecting temporal changes therein remain critical to sound public and private forestland management. The National Parks Service’s Vital Signs monitoring program collects information on many...

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...

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...

Manganese: it turns iron into steel (and does so much more)
William F. Cannon
2014, Fact Sheet 2014-3087
Manganese is a common ferrous metal with atomic weight of 25 and the chemical symbol Mn. It constitutes roughly 0.1 percent of the Earth’s crust, making it the 12th most abundant element. Its early uses were limited largely to pigments and oxidants in chemical processes and experiments, but the significance...

2014, Scientific Investigations Report 2014-5142
Precipitation, potential evapotranspiration, and actual evapotranspiration often are used to characterize the hydroclimate of a region. Quantification of these parameters in mountainous terrains is difficult because limited access often hampers the collection of representative ground data. To fulfill a need to characterize ecological zones in the Spring Mountains and Sheep...
