B.W. Case, J.L. Abraham, G. Meeker, F.D. Pooley, K.E. Pinkerton
2011, Journal of Toxicology and Environmental Health, Part B: Critical Reviews (14) 3-39
Although asbestos research has been ongoing for decades, this increased knowledge has not led to consensus in many areas of the field. Two such areas of controversy include the specific definitions of asbestos, and limitations in understanding exposure-response relationships for various asbestos types and exposure levels and disease. This document...

Comment on “An unconfined groundwater model of the Death Valley Regional Flow System and a comparison to its confined predecessor” by R.W.H. Carroll, G.M. Pohll and R.L. Hershey [Journal of Hydrology 373/3–4, pp. 316–328]
Claudia C. Faunt, Alden M. Provost, Mary C. Hill, Wayne R. Belcher
2011, Journal of Hydrology (397) 306-309
Carroll et al. (2009) state that the United States Geological Survey (USGS) Death Valley Regional Flow System (DVRFS) model, which is based on MODFLOW, is “conceptually inaccurate in that it models an unconfined aquifer as a confined system and does not simulate unconfined drawdown in transient pumping simulations.” Carroll et...

Christopher S. Swezey, Christopher P. Garrity
2011, Journal of Cave and Karst Studies (73) 125-157
Since 2006, a white fungus named Geomyces destructans has been observed on the muzzles, noses, ears, and (or) wings of bats in the eastern United States, and bat colonies that are infected with this fungus have experienced dramatic incidences of mortality. Although it is not exactly certain how and why...
USGS invasive species solutions
Annie Simpson
2011, Natural Selections (2011) 9-9
Land managers must meet the invasive species challenge every day, starting with identification of problem species, then the collection of best practices for their control, and finally the implementation of a plan to remove the problem. At each step of the process, the availability of reliable information is essential to...
Growth, morphology, and developmental instability of rainbow trout, Yellowstone cutthroat trout, and four hybrid generations
C.O. Ostberg, J.J. Duda, J.H. Graham, S. Zhang, K. P. Haywood III, B. Miller, T.L. Lerud
2011, Transactions of the American Fisheries Society (140) 334-344
Hybridization of cutthroat trout Oncorhynchus clarkii with nonindigenous rainbow trout O. mykiss contributes to the decline of cutthroat trout subspecies throughout their native range. Introgression by rainbow trout can swamp the gene pools of cutthroat trout populations, especially if there is little selection against hybrids. We used rainbow trout, Yellowstone...

Interacting vegetative and thermal contributions to water movement in desert soil
C.A. Garcia, Brian J. Andraski, David A. Stonestrom, C.A. Cooper, J. Simunek, S.W. Wheatcraft
2011, Vadose Zone Journal (10) 552-564
Thermally driven water-vapor flow can be an important component of total water movement in bare soil and in deep unsaturated zones, but this process is often neglected when considering the effects of soil–plant–atmosphere interactions on shallow water movement. The objectives of this study were to evaluate the coupled and separate...
Factors governing risk of cougar attacks on humans
David Mattson, Kenneth Logan, Linda Sweanor
2011, Human-Wildlife Interactions (5) 135-158
Since the 1980s wildlife managers in the United States and Canada have expressed increasing concern about the physical threat posed by cougars (Puma concolor) to humans. We developed a conceptual framework and analyzed 386 human– cougar encounters (29 fatal attacks, 171 instances of nonfatal contact, and 186 close-threatening encounters) to provide...
Population dynamics of Lake Ontario lake trout during 1985-2007
Travis O. Brenden, James R. Bence, Brian F. Lantry, Jana R. Lantry, Ted Schaner
2011, North American Journal of Fisheries Management (31) 962-979
Lake trout Salvelinus namaycush were extirpated from Lake Ontario circa 1950 owing to commercial and recreational fishing, predation by sea lampreys Petromyzon marinus, and habitat degradation. Since the 1970s, substantial efforts have been devoted to reestablishing a self-sustaining population through stocking, sea lamprey control, and harvest reduction. Although a stocking-supported...
Characterization of the Sonoran desert as a radiometric calibration target for Earth observing sensors
Amit Angal, Gyanesh Chander, Xiaoxiong Xiong, Tae-young Choi, Aisheng Wu
2011, Journal of Applied Remote Sensing (5)
To provide highly accurate quantitative measurements of the Earth's surface, a comprehensive calibration and validation of the satellite sensors is required. The NASA Moderate Resolution Imaging Spectroradiometer (MODIS) Characterization Support Team, in collaboration with United States Geological Survey, Earth Resources Observation and Science Center, has previously demonstrated the use of...
Contexts for change in alpine tundra
George P. Malanson, Jonathan P. Rose, P. Jason Schroeder, Daniel B. Fagre
2011, Physical Geography (32) 97-113
Because alpine tundra is responding to climate change, a need exists to understand the meaning of observed changes. To provide context for such interpretation, the relevance of niche and neutral theories of biogeography and the continuum and classification approaches to biogeographic description are assessed. Two extensive studies of alpine tundra,...
Historical legacies, information and contemporary water science and management
Daniel J. Bain, Jennifer A.S. Arrigo, Mark B. Green, Brian A. Pellerin, Charles J. Vörösmarty
2011, Water (3) 566-575
Hydrologic science has largely built its understanding of the hydrologic cycle using contemporary data sources (i.e., last 100 years). However, as we try to meet water demand over the next 100 years at scales from local to global, we need to expand our scope and embrace other data that address...

Deborah A. Reusser, Henry Lee II
2011, Journal of Biogeography (38) 1225-1239
Threats to marine and estuarine species operate over many spatial scales, from nutrient enrichment at the watershed/estuarine scale to invasive species and climate change at regional and global scales. To help address research questions across these scales, we provide here a standardized framework for a biogeographical information system containing queriable...
