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...

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...

Observations of wing-feather molt and summer feeding ecology of Steller's Eiders at Nelson Lagoon, Alaska Observations of wing-feather molt and summer feeding ecology of Steller's Eiders at Nelson Lagoon, Alaska
The population size, moult chronology, food habits, and feeding behaviour of Steller's Eiders Polysticta stelleri were studied at Nelson Lagoon, Alaska from May to October 1977. Sub-adults were flightless from late July to late August and the adult males were flightless from late August to mid September. Adult females were rarely flightless at Nelson Lagoon but commonly flightless at...

Viral erythrocytic necrosis: Some physiological consequences of infection in chum salmon (Oncorhynchus keta) Viral erythrocytic necrosis: Some physiological consequences of infection in chum salmon (Oncorhynchus keta)
Erythroid cells in chum salmon (Oncorhynchus keta) susceptible to infection with erythrocytic necrosis virus (ENV) were examined by light and electron microscopy. Cells of stages II, III, IV, V, and VI contained complete eyrthrocytic necrosis virions in the cytoplasm. Viruses closely resembling ENV were also detected in the nuclei of some erythroblasts. Some secondary consequences of ENV...

Dispersal and migratory patterns of San Francisco Bay produced herons, egrets, and terns Dispersal and migratory patterns of San Francisco Bay produced herons, egrets, and terns
San Francisco Bay, California, including its fringing marshes, supports a large and diverse water related avifauna (Grinnell and Wythe 19271 Sibley 1952, Gill 1973, 1977). Certain of man's alterations of the Bay's shallower wetlands have resulted in increased habitat diversity which has allowed colonization by several species of birds including some colonial nesting species. The...

Pomarine jaeger preys on adult black-legged kittiwake Pomarine jaeger preys on adult black-legged kittiwake
On 5 June 1977, while on a cruise in the decomposing pack ice in the Bering Sea, we observed a light phase Pomarine Jaeger (Stercorarius pomarinus) attack, kill and feed on an adult Black-legged Kittiwake (Rissa tridactyla), 1 of approximately 10 individuals within 20 m of the ship's stern. We did not observe the birds until 1 min after the initial attack and do not know if the kittiwake...

The Alaskan Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Big Delta quadrangle, Alaska The Alaskan Mineral Resource Assessment Program: Background information to accompany folio of geologic and mineral resource maps of the Big Delta quadrangle, Alaska
The geology, geochemistry, geophysics, and Landsat imagery of the Big Delta quadrangle, 16,335 km 2 in the Yukon-Tanana Upland of east-central Alaska, were investigated, and maps and reports were prepared by an interdisciplinary research team for the purpose of assessing the mineral potential. The quadrangle is dominantly a complex terrane of greenschist- to amphibolitefacies metamorphic...

Tufted Puffins nesting in estuarine habitat Tufted Puffins nesting in estuarine habitat
The Tufted Puffin (Lunda cirrhata) apparently has the most extensive breeding distribution of any North Pacific seabird, extending in the western North Pacific from Hokkaido to the north Chukotsk Peninsula on the Chukchi Sea, and in North America from Cape Lisburne on the Chukchi Sea, south to the Farallon Islands off central California (Udvardy 1963). Despite this wide breeding...
