Black brant (Branta bernicla nigricans) nest in colonies in arctic Canada, Alaska, and Russia (Derksen and Ward 1993, Sedinger et al. 1993). Virtually the entire population stages in fall at Izembek Lagoon near the tip of the Alaska Peninsula (Bellrose 1976) before southward migration (Dau 1992) to winter habitats in British Columbia, Washington, Oregon, California, and Baja California

The Alaska Volcano Observatory (AVO) responded to eruptive activity or suspected volcanic activity (SVA) at 6 volcanic centers in 1995: Mount Martin (Katmai Group), Mount Veniaminof, Shishaldin, Makushin, Kliuchef/Korovin, and Kanaga. In addition to responding to eruptive activity at Alaska volcanoes, AVO also disseminated information for the Kamchatkan Volcanic Eruption Response Team...

After the 1989 Exxon Valdez oil spill in Prince William Sound, Alaska, we studied pigeon guillemots Cepphus columba breeding just 30 km from the grounding site. The postspill population was 43% smaller than the prespill population, but we could not attribute the entire decline to the spill because a decline in this guillemot population may have predated the spill. However, relative...

Models developed from morphometric parameters are useful for estimating body mass (M) of captured wild ursids. The accuracy of those models, however, may depend on sex, season, and geographic location of the population. We tested the suitability of reported models to predict mass of polar bears (Ursus maritimus) captured in northern Alaska, but found that models developed for other...

We propose that ocean conditions of the Near Islands in the western Aleutian Arc mimic those of the shallow continental shelf of the eastern Bering Sea to the extent that the marine community, including assemblages of forage fishes and their avian predators, has distinctly coastal characteristics. In contrast, marine avifauna and their prey at neighbouring Buldir Island are distinctly...

Egg size is an important determinant of reproductive investment by birds. For many species, total investment in a clutch is limited by the size of stored reserves (Ankney and MacInnes 1978, Esler and Grand 1994a). Egg size determines the unit by which these stored reserves are partitioned. Individual females in most species of waterfowl show a high repeatability for egg size, implying...

Molting Brant in the Teshekpuk Lake Special Area (TLSA) on the Arctic Coastal Plain of Alaska were studied from 1987 to 1992 using capture-mark-recapture techniques to determine origin, age and sex composition, return rates and site fidelity. Brant originated from 10 nesting colonies in Canada and Alaska. The captured birds were 76% adults and 57% males. Ninety-one percent of

Surface and ground water in Nebraska may contain contaminants resulting from human activities. For purposes of this publication, a contaminant is any element or compound whose presence may affect the water's suitability for certain uses. For example, herbicide concentrations may exceeed the U.S. Environmental Protection Agency's (USEPA) Health Advisory Levels (HAL) for drinking water or...

The Kenai River is Alaska’s most popular salmon sport fishery. By attracting fishermen, the river contributes about $40 million annually to the local economy. Much of the fishing effort is in pursuit of the river’s chinook salmon, which are among the largest in the world. Many people benefit from the river through its numerous recreational opportunities or by making a living providing...
