Lisa L. Stillings, Michael C. Amacher
2010, Chemical Geology (269) 113-123
Phosphorite from the Meade Peak Phosphatic Shale member of the Permian Phosphoria Formation has been mined in southeastern Idaho since 1906. Dumps of waste rock from mining operations contain high concentrations of Se which readily leach into nearby streams and wetlands. While the most common mineralogical residence of Se...

Gypsies in the palace: Experimentalist's view on the use of 3-D physics-based simulation of hillslope hydrological response
A.L. James, Jeffery J. McDonnell, I. Tromp-Van Meerveld, N.E. Peters
2010, Hydrological Processes (24) 3878-3893
As a fundamental unit of the landscape, hillslopes are studied for their retention and release of water and nutrients across a wide range of ecosystems. The understanding of these near-surface processes is relevant to issues of runoff generation, groundwater-surface water interactions, catchment export of nutrients, dissolved organic carbon, contaminants (e.g....

Identification of marine-derived lipids in juvenile coho salmon and aquatic insects through fatty acid analysis
Ron A. Heintz, Mark S. Wipfli, John P. Hudson
2010, Transactions of the American Fisheries Society (139) 840-854
The energetic benefits enjoyed by consumers in streams with salmon runs depend on how those benefits are accrued. Adult Pacific salmon Oncorhynchus spp. deliver significant amounts of nutrients (i.e., nitrogen and phosphorus) and carbon to streams when they spawn and die; these nutrient additions can have demonstrable effects on primary production in...

2010, Oecologia (162) 641-651
Climate and dispersal are the two most commonly cited mechanisms to explain spatial synchrony among time series of animal populations, and climate is typically most important for fishes. Using data from 1978-2006, we quantified the spatial synchrony in recruitment and population catch-per-unit-effort (CPUE) for bloater (Coregonus hoyi) populations across lakes...

E.F. Zipkin, Royle J. Andrew, D.K. Dawson, S. Bates
2010, Biological Conservation (143) 479-484
Conservation and management actions often have direct and indirect effects on a wide range of species. As such, it is important to evaluate the impacts that such actions may have on both target and non-target species within a region. Understanding how species richness and composition differ as a result of...

Microbial arsenic metabolism: New twists on an old poison
J.F. Stolz, P. Basu, Ronald S. Oremland
2010, Microbe (5) 53-59
Phylogenetically diverse microorganisms metabolize arsenic despite its toxicity and are part of its robust iogeochemical cycle. Respiratory arsenate reductase is a reversible enzyme, functioning in some microbes as an arsenate reductase but in others as an arsenite oxidase. As(III) can serve as an electron donor for anoxygenic photolithoautotrophy and chemolithoautotrophy....
