2012, Journal of Fish Diseases (35) 775-779
Viral haemorrhagic septicaemia virus (VHSV) and its associated disease state, viral haemorrhagic septicaemia (VHS), is hypothesized to be a proximate factor accounting for the decline and failed recovery of Pacific herring populations in Prince William Sound, AK (Marty et al. 1998, 2003, 2010). Survivors of laboratory-induced VHSV epizootics develop resistance...

2012, Journal of Aquatic Animal Health (24) 195-200
Viral erythrocytic necrosis (VEN) is a condition that affects marine and anadromous fish species, including herrings and salmonids, in the Atlantic and Pacific oceans. Infection is frequently associated with severe anemia and causes episodic mortality among wild and hatchery fish when accompanied by additional stressors; VEN can be presumptively diagnosed...

2012, Geomorphology (179) 258-268
Decadal- to annual-scale analyses of changes to the fluvial form and processes of the Cedar River in Washington State, USA, reveal the effects of flow regulation, bank stabilization, and log-jam removal on a gravel-bedded river in a temperate climate. During the twentieth century, revetments were built along ~ 60% of...

2012, North American Journal of Fisheries Management (32) 1070-1079
A 4-year evaluation was conducted to determine the proportion of juvenile coho salmon Oncorhynchus kisutch passing Cowlitz Falls Dam, on the Cowlitz River, Washington, during winter. River and reservoir populations of coho salmon parr were monitored using radiotelemetry to determine if streamflow increases resulted in increased downstream movement and dam...

Jan Lovy, N.L. Lewis, P.K. Hershberger, W. Bennett, T.R. Meyers, K.A. Garver
2012, Veterinary Microbiology (161) 66-76
Viral hemorrhagic septicemia virus (VHSV) genotype IVa causes mass mortality in wild Pacific herring, a species of economic value, in the Northeast Pacific Ocean. Young of the year herring are particularly susceptible and can be carriers of the virus. To understand its pathogenesis, tissue and cellular tropisms of VHSV in...
Proceedings of the workshop on alternative futures: Accounting for growth in the Chesapeake Bay watershed
Peter R. Claggett, Renee L. Thompson, editor(s)
2012, Open-File Report 2012-1216

Geomorphic and hydrologic study of peak-flow management on the Cedar River, Washington
Christopher S. Magirl, Andrew S. Gendaszek, Christiana R. Czuba, Christopher P. Konrad, Mathieu D. Marineau
2012, Open-File Report 2012-1240
Assessing the linkages between high-flow events, geomorphic response, and effects on stream ecology is critical to river management. High flows on the gravel-bedded Cedar River in Washington are important to the geomorphic function of the river; however, high flows can deleteriously affect salmon embryos incubating in streambed gravels. A geomorphic...

Byproduct metals and rare-earth elements used in the production of light-emitting diodes—Overview of principal sources of supply and material requirements for selected markets
David R. Wilburn
2012, Scientific Investigations Report 2012-5215
The use of light-emitting diodes (LEDs) is expanding because of environmental issues and the efficiency and cost savings achieved compared with use of traditional incandescent lighting. The longer life and reduced power consumption of some LEDs have led to annual energy savings, reduced maintenance costs, and lower emissions of carbon...

2012, North American Journal of Fisheries Management (32) 1211-1224
Despite numerous negative impacts, nonnative trout are still being stocked to provide economically and socially valuable sport fisheries in western mountain lakes. We evaluated relative performance and potential differences in feeding strategy and competitive ability of triploid versus diploid brook trout Salvelinus fontinalis in alpine lakes, as well as behavioral...
Adaptive breeding habitat selection: Is it for the birds?
Anna D. Chalfoun, Kenneth A. Schmidt
2012, The Auk (129) 589-599
The question of why animals choose particular habitats has important implications for understanding behavioral evolution and distribution of organisms in the wild and for delineating between habitats of different quality for conservation and management. Habitats chosen by animals can influence fitness outcomes via the costs (e.g., predation risk) and benefits...
Constancy of local spread rates for buffelgrass (Pennisetum ciliare L.) in the Arizona Upland of the Sonoran Desert
Aaryn D. Olsson, Julio L. Betancourt, Michael A. Crimmins, Stuart E. Marsh
2012, Journal of Arid Environments (87) 136-143
In North American deserts, grass invasions threaten native vegetation via competition and altered fire regimes. Accurate prediction and successful mitigation of these invasions hinge on estimation of spread rates and their degree of constancy in time and space. We used high-resolution aerial photographs from 11 sites in the Santa Catalina...
Soil-water dynamics and unsaturated storage during snowmelt following wildfire
Brian A. Ebel, E.S. Hinckley, Deborah A. Martin
2012, Hydrology and Earth System Sciences (16) 1401-1417
Many forested watersheds with a substantial fraction of precipitation delivered as snow have the potential for landscape disturbance by wildfire. Little is known about the immediate effects of wildfire on snowmelt and near-surface hydrologic responses, including soil-water storage. Montane systems at the rain-snow transition have soil-water dynamics that are further...
