Survival of juvenile black brant during brood rearing
Paul L. Flint, James S. Sedinger, Kenneth H. Pollock
1995, Journal of Wildlife Management (59) 455-463
Survival of young is an important and poorly understood component of waterfowl productivity. We estimated survival of black brant (Branta bernicla nigricans) goslings during summers 1987-89 on the Yukon-Kuskokwim Delta, Alaska, to determine timing and magnitude of gosling mortality and to compare methods of estimating gosling survival. Eighty-two percent of...
GIS for mapping waterfowl density and distribution from aerial surveys
W.I. Butler, R.A. Stehn, G.R. Balogh
1995, Wildlife Society Bulletin (23) 140-147
We modified standard aerial survey data collection to obtain the geographic location for each waterfowl observation on surveys in Alaska during 1987-1993. Using transect navigation with CPS (global positioning system), data recording on continuously running tapes, and a computer data input program, we located observations with an average deviation along...

Metabolizability and partitioning of energy and protein in green plants by yearling lesser snow geese
James S. Sedinger, Robert G. White, Jerry W. Hupp
1995, The Condor (97) 116-122
We measured apparent metabolizability of organic matter, gross energy, nitrogen and cell wall constituents of pelleted alfalfa by Lesser Snow Geese (Chen caerulescens caerulescens. We also used simultaneous measurements of energy expenditure and apparent metabolizable energy intake to estimate heat increment of feeding and net energy for production and maintenance....
Evidence for lack of homing by sea lampreys
Roger A. Bergstedt, James G. Seelye
1995, Transactions of the American Fisheries Society (124) 235-239
Recently metamorphosed sea lampreys Petromyzon marinus were captured in the Devil River, a tributary to Lake Huron, during summer and autumn 1990. They were tagged with a coded wire tag and returned to the river to continue their migration to Lake Huron to begin the parasitic (juvenile) phase of their life. During...
Use of implanted satellite transmitters to locate Spectacled Eiders at-sea
Margaret R. Petersen, David C. Douglas, Daniel M. Mulcahy
1995, The Condor (97) 276-278
Population estimates of Spectacled Eiders (Somateria fischeri) on the Yukon-Kuskokwim Delta (YKD), Alaska, suggest that by 1992 the number of birds on this major nesting area had declined to 1,721 pairs, 4% of that estimated in the 1970s (Stehn st al 1993). Consequently, Spectacled Eiders were listed as threatened under...
Amphibians
R. Bruce Bury, P. Stephen Corn, C. Kenneth Dodd Jr., Roy W. McDiarmid, Norman J. Scott Jr.
Edward T. LaRoe, Gaye S. Farris, Catherine E. Puckett, Peter D. Doran, Michael J. Mac, editor(s)
1995, Book chapter, Our living resources: A report to the nation on the distribution, abundance, and health of U.S. plants, animals, and ecosystems
Amphibians are ecologically important in most freshwater and terrestrial habitats in the United States: they can be numerous, function as both predators and prey, and constitute great biomass. Amphibians have certain physiological (e.g., permeable skin) and ecological (e.g., complex life cycle) traits that could justify their use as bioindicators of...
Northern pintail

1995, Book chapter, Birds of North America 163
Migratory bird population changes in North Dakota
Lawrence D. Igl, Douglas H. Johnson
Edward T. LaRoe, Gaye S. Farris, Catherine E. Puckett, Peter D. Doran, Michael J. Mac, editor(s)
1995, Book chapter, Our living resources: A report to the nation on the distribution, abundance, and health of U.S. plants, animals, and ecosystems
The status of migratory bird populations in North America has received increased attention in recent years. Much of this consideration has been on Neotropical migrants, especially those associated with eastern forests. The status of migratory bird populations in the Great Plains has received far less attention. During the past quarter-century,...
Biota of the upper Mississippi River ecosystem
James G. Wiener, Teresa J. Naimo, Carl E. Korschgen, Robert Dahlgren, Jennifer S. Sauer, Kenneth S. Lubinski, Sara J. Rogers, Sandra Brewer
Edward T. LaRoe, Gaye S. Farris, Catherine E. Puckett, Peter D. Doran, Michael J. Mac, editor(s)
1995, Book chapter, Our living resources: A report to the nation on the distribution, abundance, and health of U.S. plants, animals, and ecosystems
The Mississippi River is one of the world's major river systems in size, habitat and biotic diversity, and biotic productivity. The navigable Upper Mississippi River, extending 1,370 km (850 mi) from St. Anthony Falls (Minnesota) to the confluence with the Ohio River, has been impounded by 27 locks and dams...
