Ecoregions of Alaska
Alisa L. Gallant, Emily F. Binnian, J.M. Omernik, M.B. Shasby
1995, Professional Paper 1567
This publication represents a milestone in the U.S. global change research program on the land characterization of Arctic land processes. The book describes 20 ecological regions and includes a folded, color-coded map that shows them. The map legend summarizes the characteristics of each region and has 41 color photographs of...
Wolf predation on caribou calves in Denali National Park, Alaska
Layne G. Adams, B. Dale, L. David Mech
Ludwig N. Carbyn, Steven H. Fritts, Dale R. Seip, editor(s)
1995, Conference Paper, Ecology and conservation of wolves in a changing world: Proceedings of the second North American symposium on wolves: Occasional Publication 35
During 1987-1991, 29 to 45 radio-collared caribou cows were monitored daily during calving each year and their calves were radio-collared (n = 147 calves) to investigate calf production and survival. We determined characteristics of wolf predation on caribou calves and, utilizing information from a companion wolf study, evaluated the role...
Population size, trends, and conservation problems of the Double-Crested Cormorant on the Pacific Coast of North America
Harry R. Carter, Arthur L. Sowls, M. S. Rodway, Ulrich W. Wilson, Roy W. Lowe, Gerard J. McChesney, Franklin Gress, Daniel W. Anderson
1995, Colonial Waterbirds (18) 189-215
Population size, trends and conservation problems of the Double-crested Cormorant (Phalacrocorax auritus) were collated for the Pacific coast of North America using available data up to 1992. About 54,942 birds currently breed there, including roughly 5,848 (5,622 at 90 coastal colonies and at least 226 at 5 interior colonies) and...
The influence of life history trade-offs and the size of the incubation gravels on egg size variation in sockeye salmon Onchorhynchus nerka
Thomas P. Quinn, Andrew P. Hendry, Lisa A. Wetzel
1995, Oikos (74) 425-438
Egg size is a critical life history trait, reflecting female investment and affecting off- spring fitness. We investigated several factors which may influence variation in egg weight for sockeye salmon (Oncorhynchus nerka). Comparisons were based on col- lections from 18 Alaskan populations, among which adult migration distance and ju-...
A review of the geochemistry of methane in natural gas hydrate
Keith A. Kvenvolden
1995, Organic Geochemistry (23) 997-1008
The largest accumulations on Earth of natural gas are in the form of gas hydrate, found mainly offshore in outer continental margin sediment and, to a lesser extent, in polar regions commonly associated with permafrost. Measurements of hydrocarbon gas compositions and of carbon-isotopic compositions of methane from natural gas hydrate...
