David Harmon, editor(s)
2006, Book chapter, People, Places, and Parks: Proceedings of the 2005 George Wright Society Conference on Parks, Protected Areas, and Cultural Sites
The Biomonitoring of Environmental Status and Trends (BEST) Project of the U.S. Geological Survey (USGS) assesses the exposure and effects of environmental contaminants on select species and habitats in the United States. One of the many BEST Project activities entails the development of decision-support tools to assist in the...
Adaptive harvest management of North American waterfowl populations - recent successes and future prospects
J.D. Nichols, M.C. Runge, Fred A. Johnson, B. Kenneth Williams
Richard Schodde, Susan Hannon, Gregor Scheiffarth, Franz Bairlein, editor(s)
2006, Book chapter, XXIV International Ornithological Congress, Hamburg, 2006, Abstracts
The history of North American waterfowl harvest management has been characterized by attempts to use population monitoring data to make informed harvest management decisions. Early attempts can be characterized as intuitive decision processes, and later efforts were guided increasingly by population models and associated predictions. In 1995, a...

Matthew C. Perry, D.M. Kidwell, A.M. Wells, E.J.R. Lohnes, P.C. Osenton, S.H. Altmann
Alan Hanson, Joseph Kerekes, Julie Paquet, editor(s)
2006, Book chapter, Limnology and Waterbirds 2003. The 4th Conference of the Aquatic Birds Working Group of the Societas Internationalis Limnologiae (SIL)
We analyzed characteristics of wetland habitats used by breeding black scoters (Melanitta nigra) and surf scoters (M. perspicillata) in the eastern boreal forest and subarctic regions of Canada based on satellite telemetry data collected in the spring and summer. During 2002 and 2004, nine black scoters (four males, five...
Impacts of marsh management on coastal-marsh bird habitats
L.R. Mitchell, S. Gabrey, P.P. Marra, R.M. Erwin
2006, Book chapter, Terrestrial vertebrates of tidal marshes: evolution, ecology, and conservation
The effects of habitat-management practices in coastal marshes have been poorly evaluated. We summarize the extant literature concerning whether these manipulations achieve their goals and the effects of these manipulations on target (i.e., waterfowl and waterfowl food plants) and non-target organisms (particularly coastal-marsh endemics). Although we focus on...
Five years (2000-2004) of post-reconstruction monitoring of freshwater tidal wetlands in the urban Anacostia River, Washington, D.C. USA

Barnett A. Rattner, B.K. Ackerson
2006, Report
Part of the mission of the National Park Service is to preserve the natural resources, processes, systems, and associated values of its units in an unimpaired condition. Environmental contamination and pollution processes are well recognized stressors addressed by its management policies and plans. A recent study indicates that contemporary...
Geochemistry of the Amazon Estuary
Joseph M. Smoak, James M. Krest, Peter W Swarzenski
2006, Book chapter, Handbook of environmental chemistry
The Amazon River supplies more freshwater to the ocean than any other river in the world. This enormous volume of freshwater forces the estuarine mixing out of the river channel and onto the continental shelf. On the continental shelf, the estuarine mixing occurs in a very dynamic environment unlike that of...
The utility of gravity and magnetic methods for understanding subsurface hydrogeology in large alluvial watersheds: Examples from urbanized basins of the Western United States
V. J. S. Grauch, Victoria Langenheim
2006, Conference Paper, Symposium on the application of geophysics to engineering and environmental problems proceedings
Population continues to grow rapidly within the large alluvial watersheds associated with structural basins of the Basin and Range Province and the Rio Grande rift of the western United States. Increasing demands on ground‐water resources in these basins, combined with water‐rights disputes, have amplified the need for improved understanding of...

Concentrations, loads, and yields of particle-associated contaminants in urban creeks, Austin, Texas, 1999-2004
B.J. Mahler, P. C. Van Metre, J.T. Wilson, A.L. Guilfoyle, M.W. Sunvison
2006, Scientific Investigations Report 2006-5262
Concentrations, loads, and yields of particle-associated (hydrophobic) contaminants (PACs) in urban runoff in creeks in Austin, Texas, were characterized using an innovative approach: large-volume suspended-sediment sampling. This approach isolates suspended sediment from the water column in quantities sufficient for direct chemical analysis of PACs. During 1999-2004, samples were collected after...
Integrated Science: Providing a More Complete Understanding of Complex Problems
Water Resources Division, U.S. Geological Survey
2006, Fact Sheet 2006-3056
Integration among sciences is critical in order to address some of our most pressing problems. Because of the inherent complexity of natural systems, and the increasing complexity of human demands on them, narrowly-focused approaches are no longer sufficient. USGS Workshop on Enhancing Integrated Science, November 1998. The Mid-Continent Geographic Science Center is...
