Breeding biology of Pacific white-fronted geese
Craig R. Ely, Dennis G. Raveling
1984, Journal of Wildlife Management (48) 823-837
Nesting ecology of Pacific white-fronted geese (Anser albifrons frontalis) was studied on a 9.9-km2 area on the Yukon-Kuskokwim (Y-K) Delta, Alaska, during 1977-79. Availability of nesting habitat varied considerably among years because of differences in time of snow- and icemelt. Mean clutch size was 3.7 eggs in the late spring...
Titre distribution patterns of infectious haematopoietic necrosis virus in ovarian fluids of hatchery and feral salmon populations
D. Mulcahy, R.J. Pascho, C.K. Jenes
1983, Journal of Fish Diseases (6) 183-188
Infectious haematopoietic mecrosis virus (IHNV) is enzootic in virtually all populations of sockeye salmon, Oncorhynchus nerka (Walbaum), and in populations of chinook salmon, O. tshawytscha (Walbaum), of the Sacramento River drainage in California. This disease is an obstacle in hatcheries using brood stocks from these populations. However, naturally spawning sockeye...
Effect of loading density of sockeye salmon, Oncorhynchus nerka (Walbaum), eggs in incubation boxes on mortality caused by infectious haematopoietic necrosis
D. Mulcahy, K. Bauersfeld
1983, Journal of Fish Diseases (6) 189-193
Infectious haematopoietic necrosis (IHN) can cause massive mortalities of sockeye salmon, Oncorhynchus nerka (Walbaum), cultured in hatcheries. One method of enhancing sockeye salmon populations is to use a streamside egg incubation box from which the fry are automatically released into the stream as they emerge from the gravel. In this...
Nest sites and eggs of Kittlitz's and Marbled murrelets
Robert H. Day, Karen L. Oakley, D.R. Barnard
1983, Condor (85) 265-273
Fourteen known and three probable nests of Kittlitz's Murrelet (Brachyramphus brevirostris) and eight known and one probable nest of Marbled Murrelet (B. marmoratus) have been reported. Nests of Kittlitz's Murrelet tend to be at higher elevations and farther inland than those of Marbled Murrelet. Kittlitz's nests have much less vegetative...

Habitat Suitability Index Models: Coho salmon
Thomas E. McMahon
1983, FWS/OBS 82/10.49
The coho salmon (Oncorhynchus kisutch) is native to the northern Pacific Ocean, spawning and rearing in streams from Monterey Bay, California, to Point Hope, Alaska, and southward along the Asiatic coast to Japan. Its center of abundance in North America is from Oregon to Alaska (Briggs 1953; Godfrey 1965; Hart...

Structure maps and seismic stratigraphy of the Yakataga segment of the continental margin, northern Gulf of Alaska
T.R. Bruns, W. C. Schwab
1983, Miscellaneous Field Studies Map 1424
Multichannel seismic-reflection data show the late Cenozoic structure, seismic stratigraphy, and geologic history of the Yakataga segment of the continental margin, between Icy Bay and Kayak Island, northern Gulf of Alaska. The structure of the Yakataga segment consists of broad folds and associated thrust faults beneath the continental shelf and...
