Population genetic studies of the polar bear (Ursus maritimus): A summary of available data and interpretation of results
Kim T. Scribner, G.W. Garner, Steven C. Amstrup, M.A. Cronin
Andrew E. Dizon, Susan J. Chivers, William F. Perrin, editor(s)
1997, Book chapter, Molecular Genetics of Marine Mammals: Special Publication 3
A summary of existing population genetics literature is presented for polar bears (Ursus maritimus) and interpreted in the context of the species' life-history characteristics and regional heterogeneity in environmental regimes and movement patterns. Several nongenetic data sets including morphology, contaminant levels, geographic variation in reproductive characteristics, and the location and...
Mass-mortality of guillemots (Uria aalge) in the Gulf of Alaska in 1993
John F. Piatt, Thomas I. van Pelt
1997, Marine Pollution Bulletin (34) 656-662
During the first six months of 1993, about 3500 dead and moribund guillemots (Uria aalge) were observed throughout the northern Gulf of Alaska coast (ca 1800 km range). Mortality peaked during March. Highest numbers were observed in western Prince William Sound and along the south coast of the Kenai Peninsula....
Investigating trophic relationships of pinnipeds in Alaska and Washington using stable isotope ratios of nitrogen and carbon
Keith A. Hobson, John L. Sease, Richard L. Merrick, John F. Piatt
1997, Marine Mammal Science (13) 114-132
We measured stable-nitrogen (δ15N) and stable-carbon (δ13C) isotope ratios in muscle and hair from 7 northern fur seals (Callorhinus ursinus) from the Pribilof Islands, Alaska, and 27 Steller sea lions (Eumetopias jubatus), and 14 harbor seals (Phoca vitulina) from the Gulf of Alaska and coast of Washington State, in order...
California salmon and steelhead: Beyond the crossroads
Terry J. Mills, Dennis R. McEwan, Mark R. Jennings
Deanna J. Stouder, Peter A. Bisson, Robert J. Naiman, editor(s)
1997, Book chapter, Pacific salmon and their ecosystems: Status and future options
Virtually all California salmon (Oncorhynchus spp.) and steelhead (O. mykiss) stocks have declined to record or near-record low levels during 1980-95. Escapement of naturally spawning Klamath and Sacramento basin fall-run chinook salmon (O. tshawytscha) stocks has fallen consistently below the goals of 35,000...
Pasteurella multocida serotype 1 isolated from a lesser snow goose
M.D. Samuel, Diana R. Goldberg, D.J. Shadduck, J.I. Price, E.G. Cooch
1997, Journal of Wildlife Diseases (33) 332-335
Pharyngeal swabs were collected from 298 lesser snow geese (Chen caerulescens caerulescens) at Banks Island (Northwest Territories. Canada) in the summer of 1994. Pasteurella multocida serotype 1 was isolated from an adult male bird and P. multocida serotype 3 was isolated from an adult female goose. Pathogenicity of the serotype...
Isolation and characterization of novel waterfowl microsatellite loci: Cross-species comparisons and research applications
R.L. Fields, Kim T. Scribner
1997, Molecular Ecology (6) 199-202
Waterfowl constitute an ecologically diverse group which are the subject of extensive research (e.g. see reviews in Batt et al. 1992), and are intensively managed (Nichols et al.1995). Genetic studies utilizing allozyme electrophoresis and mitochondrial (mt)DNA have provided valuable information on waterfowl ecology and evolutionary history (Cooke & Buckley 1987)....
Population genetics studies of the walrus (Odobenus rosmarus): A summary and interpretation of results and research needs
Kim T. Scribner, Susan Hills, Steven R. Fain, Matthew A. Cronin
Andrew E. Dizon, Susan J. Chivers, William F. Perrin, editor(s)
1997, Book chapter, Molecular Genetics of Marine Mammals: Special Publication 3
A summary of population genetics data is presented for the walrus (Odobenus rosmarus). Current information on the ecology and behavior of the species is highlighted to aid in the interpretation of genetics results and to suggest future areas of research. Walruses are discontinuously distributed across the Arctic and are currently...
Aerial videography for estimating goose populations staging in Izembek Lagoon, Alaska
R.M. Anthony, R.A. Stehn, W.H. Anderson
1997, Conference Paper, Proceedings of the 16th biennial workshop on color photography and videography in resource assessment
We conducted experimental photographic surveys of black brant and Canada geese in a pre-migration staging area on the Alaska Peninsula to compare precision and efficiency of this technique to currently employed ocular estimates. Video and digital cameras sensitive to near infrared and visible radiation were tested at various altitudes and...
In situ relations of target strength to fish size for Great Lakes pelagic planktivores
Guy W. Fleischer, Ray L. Argyle, Gary L. Curtis
1997, Transactions of the American Fisheries Society (126) 786-794
We found mean target strength to be a reliable in situ predictor of fish weight, which allows direct estimation of the pelagic planktivore fish biomass from target strength measurements. Fish were collected by midwater trawling concurrent with target strength measurements (120-kHz frequency) in Lake Michigan. The mean weight of fish...
[Book review] Metapopulations and the real world
Douglas H. Johnson
