Steven C. Amstrup, George M. Durner, I. Stirling, T. L. McDonald
2005, Arctic (58) 247-259
Recognition that polar bears are shared by hunters in Canada and Alaska prompted development of the “Polar Bear Management Agreement for the Southern Beaufort Sea.” Under this Agreement, the harvest of polar bears from the southern Beaufort Sea (SBS) is shared between Inupiat hunters of Alaska and Inuvialuit hunters of...
Fire history of the San Francisco East Bay region and implications for landscape patterns
Jon E. Keeley
2005, International Journal of Wildland Fire (14) 285-296
The San Francisco East Bay landscape is a rich mosaic of grasslands, shrublands and woodlands that is experiencing losses of grassland due to colonization by shrubs and succession towards woodland associations. The instability of these grasslands is apparently due to their disturbance-dependent nature coupled with 20th century changes in fire...
Advancing migratory bird conservation and management by using radar: An interagency collaboration
Janet M. Ruth, Wylie C. Barrow, Richard S. Sojda, Deanna K. Dawson, Robert H. Diehl, Albert Manville, Michael T. Green, David J. Krueper, Scott Johnston
2005, Open-File Report 2005-1173
Migratory birds face many changes to the landscapes they traverse and the habitats they use. Wind turbines and communications towers, which pose hazards to birds and bats in flight, are being erected or proposed across the United States and offshore. Human activities can also destroy or threaten habitats critical to...

Monitoring temporal change in riparian vegetation of Great Basin National Park
Erik A. Beever, David A. Pyke, Jeanne C. Chambers, Fred Landau, S.D. Smith
2005, Western North American Naturalist (65) 382-402
Disturbance in riparian areas of semiarid ecosystems involves complex interactions of pulsed hydrologic flows, herbivory, fire, climatic effects, and anthropogenic influences. We resampled riparian vegetation within ten 10-m × 100-m plots that were initially sampled in 1992 in 4 watersheds of the Snake Range, east central Nevada. Our finding of...

R.A. Rounds, R.M. Erwin, J.H. Porter
2004, Journal of Field Ornithology (75) 317-329
Rising sea levels in the mid-Atlantic region pose a long-term threat to marshes and their avian inhabitants. The Gull-billed Tern (Sterna nilotica), Common Tern (S. hirundo), Black Skimmer (Rynchops niger), and American Oystercatcher (Haematopus palliatus), species of concern in Virginia, nest on low shelly perimeters of salt marsh islands on...
Estimating survival and breeding probability for pond-breeding amphibians: a modified robust design
L.L. Bailey, W. L. Kendall, D.R. Church, H.M. Wilbur
2004, Ecology (85) 2456-2466
Many studies of pond-breeding amphibians involve sampling individuals during migration to and from breeding habitats. Interpreting population processes and dynamics from these studies is difficult because (1) only a proportion of the population is observable each season, while an unknown proportion remains unobservable (e.g., non-breeding adults) and (2) not all...

Christopher L. Braun, Glenn R. Harwell
2004, Fact Sheet 2004-3077
In spring 2000, the Texas Department of Health issued a fish-consumption advisory for Lake Worth, Tex., because of elevated concentrations of polychlorinated biphenyls (PCBs) in fish (Texas Department of Health, 2000). In response to the advisory and in cooperation with the U.S. Air Force, the U.S. Geological Survey (USGS) collected...

Tree-regeneration and mortality patterns and hydrologic change in a forested karst wetland--Sinking Pond, Arnold Air Force Base, Tennessee
William J. Wolfe, Jonathan P. Evans, Sarah McCarthy, W. Scott Gain, Bradley A. Bryan
2004, Water-Resources Investigations Report 2003-4217
Multiple lines of evidence point to climate change as the driving factor suppressing tree regeneration since 1970 in Sinking Pond, a 35-hectare seasonally flooded karst depression located on Arnold Air Force Base near Manchester, Tennessee. Annual censuses of 162-193 seedling plots from 1997 through 2001 demonstrate that the critical stage...
