Temporal, spatial, and environmental influences on the demographics of grizzly bears in the Greater Yellowstone Ecosystem
Charles C. Schwartz, Mark A. Haroldson, Gary C. White, Richard B. Harris, Steve Cherry, Kim A. Keating, Dave Moody, Christopher Servheen
2006, Book
During the past 2 decades, the grizzly bear (Ursus arctos) population in the Greater Yellowstone Ecosystem (GYE) has increased in numbers and expanded in range. Understanding temporal, environmental, and spatial variables responsible for this change is useful in evaluating what likely influenced grizzly bear demographics in the GYE and where...
Estimating Potential Effects of Hypothetical Oil Spills on Polar Bears
Steven C. Amstrup, George M. Durner, T. L. McDonald, W.R. Johnson
2006, Report
Much is known about the transport and fate of oil spilled into the sea and its toxicity to exposed wildlife. Previously, however, there has been no way to quantify the probability that wildlife dispersed over the seascape would be exposed to spilled oil. Polar bears, the apical predator of the...
Attitudes and perceptions about prairie dogs
Berton Lee Lamb, Richard P. Reading, William F. Andelt
John L. Hoogland, editor(s)
2006, Book chapter, Conservation of the black-tailed prairie dog: Saving North America's western grasslands
We sometimes get the impression that all ranchers and farmers of the western United States hate prairie dogs, and that people everywhere else love them. This generality contains elements of truth, but better documentation of attitudes and perceptions is paramount for good conservation. In this chapter we examine attitudes and...
Recruitment of Hexagenia mayfly nymphs in western Lake Erie linked to environmental variability
Thomas B. Bridgeman, Don W. Schloesser, Ann E. Krause
2006, Ecological Applications (16) 601-611
After a 40-year absence caused by pollution and eutrophication, burrowing mayflies (Hexagenia spp.) recolonized western Lake Erie in the mid 1990s as water quality improved. Mayflies are an important food resource for the economically valuable yellow perch fishery and are considered to be major indicator species of the ecological condition...

Use of electric and bubble barriers to limit the movement of Eurasian ruffe (Gymnocephalus cernuus)
Heather A. Dawson, Ulrich G. Reinhardt, Jacqueline F. Savino
2006, Journal of Great Lakes Research (32) 40-49
Eurasian ruffe (Gymnocephalus cernuus) is an aquatic invasive species accidentally introduced via ballast water to the Great Lakes in the mid-1980s. Fish barrier technology is being studied to stop the spread of invasive fish species such as ruffe. Electrical barriers have been constructed, most notably in the Chicago Sanitary and...
Recurring waterbird mortalities and unusual etiologies
Rebecca A. Cole, J. Christian Franson
Gerard C. Boere, Colin A. Galbraith, David A. Stroud, editor(s)
2006, Conference Paper, Waterbirds around the world: A global overview of the conservation, management, and research of the world's waterbird flyways
Over the last decade, the National Wildlife Health Center of the United States Geological Survey has documented various largescale mortalities of birds caused by infectious and non-infectious disease agents. Some of these mortality events have unusual or unidentified etiologies and have been recurring. While some of the causes of mortalities...
Educating veterinarians for careers in free-ranging wildlife medicine and ecosystem health
J.A.K. Mazet, G.E. Hamilton, L.A. Dierauf
2006, Journal of Veterinary Medical Education (33) 352-360
In the last 10 years, the field of zoological medicine has seen an expansive broadening into the arenas of free-ranging wildlife, conservation medicine, and ecosystem health. During the spring/summer of 2005, we prepared and disseminated a survey designed to identify training and educational needs for individuals entering the wildlife medicine...

Timothy P. Brabets, Robert T. Ourso
2006, Scientific Investigations Report 2006-5151
The U.S. Geological Survey and the National Park Service conducted a water-quality investigation of the Crescent River Basin in Lake Clark National Park and Preserve from May 2003 through September 2004.

Disease emergence and resurgence—the wildlife-human connection
Milton Friend, James W. Hurley, Pauline Nol, Katherine E. Wesenberg
2006, Circular 1285
