Ross’ Gulls (Rhodostethia rosea) are a major component of the pelagic avifauna of the Alaskan Chukchi and Beaufort seas in fall. Until recently, however, their distribution, abundance, and phenology of occurrence in Alaskan waters was poorly known. Since 1970, a combination of shipboard, aerial, and land-based surveys has revealed the major features of this species’ post-breeding...

Since 1984, the Alaska Fish and Wildlife Research Center, in cooperation with the Alaska Department of Fish and Game and several other agencies, has used the Argos Data Collection and Location System to address wildlife research and management problems in Alaska and other parts of North America. The use of satellite telemetry has overcome some of the logistical problems of working in...

Artificial goose nests were used to determine what factors might increase predation after visits to nests of Cackling Canada Geese (Branta canadensis minima). We tested whether leaving the nest uncovered, marking the nest location with a flag, or placing the nest on an island or peninsula would increase the rate of predation. Predators destroyed significantly more of the nests with eggs...

The contact between the Upper Cretaceous Valdez Group and the Paleocene and Eocene Orca Group has been inferred to be the boundary between the Chugach and the Prince William tectonostratigraphic terranes. Sandstone petrographic data from the Prince William Sound area show no compositional discontinuity across this contact. These data are best explained by considering the Valdez and Orca...

Migrant Whimbrels (Numenius phaeopus) and Bristle-thighed Curlews (N. tahitiensis) were recorded during five summers along coastal tundra of the Yukon-Kuskokwim Delta, Alaska. From June to September, 1975-1979, 358 flocks totalling 1,265 curlews were observed; an additional 54 flocks were identified by vocalization alone. Among the 359 flocks identified to species, 52% were of Whimbrels...

Carbonate rocks characterized by locally abundant stromatolites and coated grains have been found at several localities in the Baird Mountains and Ambler River quadrangles (fig. 1). These rocks are part of a belt of metasedimentary and metaigneous rocks that constitutes the southwestern flank of the Brooks Range; all are included in the parautochthon (Schwatka sequence) of Mayfield and...

Visual surveys along subtidal belt transects were used to compare fish assemblages on an experimental and a control site before and after the removal of a canopy-forming kelp forest. The giant kelp Macrocystis pyrifera (L.) C.A. Agardh was removed at the holdfast from ≈ 1 ha of high relief structurally complex rock substratum. The abundance of seven species of fish, of which five were...

Samples of kidney, spleen, coelomic fluid, and blood from 56 sexually mature coho salmon Oncorhynchus kisutch were examined for infection by Renibacterium salmoninarum by five methods. The overall prevalence (all sample types combined) of R. salmoninarum in the fish was 100% by the enzyme-linked immunosorbent assay, 86% by the combined results of the direct fluorescent antibody and the...

Infectious hematopoietic necrosis (IHN) virus is usually detected by inoculating susceptible cell cultures with cavity ("ovarian") fluid (CF) from spawning females. We identified additional adult carriers of virus in spawning populations of steelhead trout (Salmo gairdneri) and sockeye salmon (Oncorhynchus nerka) by collecting nonerythrocytic cells from CF samples by low-speed...

The geology, geochemistry, geophysics, and Landsat imagery of the Circle quadrangle were investigated by an interdisciplinary research team for the purpose of assessing the mineral potential of the area. The quadrangle covers approximately 15,765 km2 in east-central Alaska; most of it is included in the mountainous Yukon-Tanana Upland physiographic division, but the northernmost part is...
