Shorebirds of the eastern Bering Sea Shorebirds of the eastern Bering Sea
Largely on the basis of work conducted in western Alaska since 1975, we present an overview of the shorebird resources of the region and discuss their relationship to the littoral and supralittoral habitats of the area. Thirty species of shorebirds occur regularly and comprise an important component of the eastern Bering Sea ecosystem. For a third of these species the region supports the...

The Alaskan Mineral Resource Assessment Program; background information to accompany folio of geologic and resources maps of the Chignik and Sutwik Island quadrangles, Alaska The Alaskan Mineral Resource Assessment Program; background information to accompany folio of geologic and resources maps of the Chignik and Sutwik Island quadrangles, Alaska
The Chignik and Sutwik Island quadrangles (1:250,000) are a part of the Alaska Peninsula in southwestern Alaska. This circular and a companion folio of maps represent results of integrated field and laboratory studies by an interdisciplinary team on geology, geophysics, geochemistry, mineral resources, geochronology, and energy resources to provide a modern assessment of the mineral and...

An annotated bibliography of literature on Alaska water birds An annotated bibliography of literature on Alaska water birds
The demand for information on birds in Alaska has surged within the past few years, primarily because of the need to adequately assess the impacts of a wide range of planned developments. The accompanying increase in studies of avian populations has resulted in a growing need for a comprehensive bibliography of Alaska ornithology. An initial effort by Bartonek and Lensink (1978) provided...

Populations, feeding ecology and molt of Steller's Eiders Populations, feeding ecology and molt of Steller's Eiders
This study considers the temporal and spatial distribution of Steller's Eiders (Polysticta stelleri) during molt along the north side of the Alaska Peninsula from Port Heiden to Bechevin Bay. Subadult eiders molted primarily at Nelson Lagoon, adult males at Nelson Lagoon and Izembek Bay, and adult females primarily at Izembek Bay. Only a few eiders used Bechevin Bay, Seal Islands, and...

K-Ar ages on intrusive and altered zones in the Chignik and Sutwik Island quadrangles: A section in The United States Geological Survey in Alaska: Accomplishments during 1979 K-Ar ages on intrusive and altered zones in the Chignik and Sutwik Island quadrangles: A section in The United States Geological Survey in Alaska: Accomplishments during 1979
Continued K-Ar dating of intrusive rocks and hydrothermal alteration zones in the Chignik and Sutwik Island quadrangles of the Alaska Peninsula, supplemental to that by Wilson, Detterman, and Silberman (1978) and Wilson (1978), has refined our knowledge of the ages of the igneous rocks and clarified relations between altered zones and igneous events in the area.

Strains of infectious hematopoietic necrosis (IHN) virus may be identified by structural protein differences Strains of infectious hematopoietic necrosis (IHN) virus may be identified by structural protein differences
The development of an effective vaccine to infectious hematopoietic necrosis virus (IHNV) in fish requires a knowledge of the virus serotypes in nature. At least two serotypes were found among three IHNV strains (12). Attempts in our laboratory to extend this study with additional virus strains by classical immunological techniques were unsatisfactory. Thus, we sought another method for...

The United States Geological Survey in Alaska: Accomplishments during 1979 The United States Geological Survey in Alaska: Accomplishments during 1979
This circular describes the 1980 programs of the U.S. Geological Survey in Alaska. A brief description of the Alaskan operations of each major division of the Survey is followed by project descriptions arranged by geographic regions in which the work takes place. The mission of the Geological Survey is to identify the Nation 's land, water, energy, and mineral resources; to classify...
Birds of the northcentral Alaska Peninsula, 1976-1980 Birds of the northcentral Alaska Peninsula, 1976-1980
Between spring 1976 and fall 1980 we studied the occurrence, abundance, and habitat use of birds over a 2000 square km segment of the northcentral Alaska Peninsula. During this period observers were present 473 days and obtained records for all seasons. A total of 125 species was recorded; 63% (79 of 125) were water-associated. The breeding avifauna was found to be a mixture of Panboreal...

Channelization and livestock impacts on salmonid habitat and biomass in western Washington Channelization and livestock impacts on salmonid habitat and biomass in western Washington
We examined salmonid habitat and biomasses in 50–70‐m pairs of altered and control sections of small (discharges less than 0.3 m3second−1) streams around Puget Sound in western Washington in 1978–1979. Altered sections had been channelized or used by livestock. Channelization significantly reduced overhead cover, sinuosity, wetted area, and woody bank cover while increasing bank grasses...
