As part of the U.S. Geological Survey (USGS) and Department of Defense Task Force for Business and Stability Operations (TFBSO) natural resources revitalization activities in Afghanistan (Peters and others, 2011), three new datasets have been collected, compiled, and analyzed. These data have been used to more fully evaluate the areas...
Real-time seismic monitoring of structures: Data handling and case studies
Mehmet Celebi
2011, Book chapter, Earthquake data in engineering seismology: Predictive models, data management and networks
Within the last decade, advances in the acquisition, processing and transmission of data from real-time seismic monitoring systems has contributed to the growth in the number structures instrumented with such systems. An equally important factor for such growth can be attributed to the demands by stakeholders to find rapid answers...

Susan E Hough, Doug Given, Tomoyo Taniguchi, J.R. Altidor, Dieuseul Anglade, S-L. Mildor
2011, Conference Paper
No strong motion records are available for the 12 January 2010 M7.0 Haiti earthquake. We use aftershock recordings as well as detailed considerations of damage to estimate the severity and distribution of mainshock shaking in Port-au-Prince. Relative to ground motions at a hard - rock reference site, peak accelerations...

Lee A. Vierling, Sebastián Martinuzzi, Gregory P. Asner, Jason M. Stoker, Brian R. Johnson
2011, Frontiers in Ecology and the Environment (9) 261-262
Since the days of MacArthur, three-dimensional (3-D) structural information on the environment has fundamentally transformed scientific understanding of ecological phenomena (MacArthur and MacArthur 1961). Early data on ecosystem structure were painstakingly laborious to collect. However, as reviewed and reported in recent volumes of Frontiers(eg Vierling et al. 2008; Asner et...
Distribution and abundance of stream fishes in relation to barriers: implications for monitoring stream recovery after barrier removal
Joseph D. Zydlewski, Stephen M. Coghlan Jr., C. Gardner, R. Saunders
2011, River Research and Applications (29) 65-78
Dams are ubiquitous in coastal regions and have altered stream habitats and the distribution and abundance of stream fishes in those habitats by disrupting hydrology, temperature regime and habitat connectivity. Dam removal is a common restoration tool, but often the response of the fish assemblage is not monitored rigorously. Sedgeunkedunk...

Julie D. Rosati, Ping Wang, Tiffany M. Roberts, editor(s)
2011, Book, The Proceedings of the Coastal Sediments 2011
Current regulations in California prohibit the disposal of more than 20% fine-grained sediment in the coastal zone; this threshold is currently being investigated to determine if this environmental regulation can be improved upon. A field monitoring and numerical modeling experiment took place late 2 009 to determine the fate...
Measuring the impacts of natural amenities and the US-Mexico Border, on housing values in the Santa Cruz Watershed, using spatially-weighted hedonic modeling
Gladys Amaya, Laura M. Norman, George Frisvold
2011, Conference Paper, Proceedings of Santa Cruz River Researchers' Day
Assessing the sustainability of International policy or urban development requires consideration of the impacts of these decisions on Ecosystem Services, or the values that humans receive from the ecosystem, including market-land price, environmental, and human well-being values. Hedonic modeling helps to identify the market land price, considering the price is...

Dana L. Winkelman
Paul H. Michaletz, Vincent H. Travnichek, editor(s)
2011, Book chapter, Conservation, Ecology, and Management of Catfish: The Second International Symposium
I conducted a 3-year study at Lake Carl Blackwell, Oklahoma to estimate effects of various fishing gears on the flathead catfish Pylodictis olivaris population. Managers were particularly interested in the effect of handfishing or noodling on this population. I used a phone survey to assess angler effort and electrofishing and...

Robert F. Breault
2011, Scientific Investigations Report 2011-5004
Polychlorinated biphenyls (PCBs) are known to contaminate the Neponset River, which flows through parts of Boston, Massachusetts, and empties into the Neponset River Estuary, an important fish-spawning area. The river is dammed and impassable to fish. The U.S. Geological Survey, in cooperation with the Massachusetts Department of Fish and Game,...

2011, Journal of Biogeography (38) 1368-1380
Aim Glacial refugia during the Pleistocene had major impacts on the levels and spatial apportionment of genetic diversity of species in northern latitude ecosystems. We characterized patterns of population subdivision, and tested hypotheses associated with locations of potential Pleistocene refugia and the relative contribution of these refugia to the post-glacial colonization...

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...

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...
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,...
