Plaquing procedure for infectious hematopoietic necrosis virus

A single overlay plaque assay was designed and evaluated for infectious hematopoietic necrosis virus. Epithelioma papillosum carpio cells were grown in normal atmosphere with tris(hydroxymethyl)aminomethane- or HEPES (N-2-hydroxyethylpiperazine-N'-2-ethanesulfonic acid)-buffered media. Plaques were larger and formed more quickly on 1- to 3-day-old...

Two Cenozoic igneous events on the Alaska Peninsula: A section in Geological Survey research 1980

Potassium-argon dating work and geologic mapping in the Chignik and Sutwik Island quadrangles (loc. 23) by F. H. Wilson, R. L. Detterman, J. E. Case, M. E. Yount, and others (Wilson and others, 1978; Detterman and others, 1979) have shown the existence of two major Cenozoic igneous episodes on the Alaska Peninsula. These events range in age from...

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...

A preliminary assessment of the timing and migration of shorebirds along the northcentral Alaska Peninsula

An intensive study of post-breeding and migrating shorebirds was conducted in 1976 on a major estuary of the Alaska Peninsula at Nelson Lagoon. Twenty species were recorded, eight of them breeding on the study area. Temporal patterns of relative abundance were obtained from aerial and ground censuses. Prominent events in the seasonal southward...

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...

Nesting ecology of Arctic loons

Arctic Loons were studied on the Yukon-Kuskokwim Delta, Alaska, from the time of their arrival in May to their departure in September, in 1974 and 1975. Pairs arrived on breeding ponds as soon as sufficient meltwater was available to allow their take-off and landing. Loons apparently do not initiate nests immediately after their arrival, even when...

Paleozoic rocks on the Alaska Peninsula: A section in The United States Geological Survey in Alaska: Accomplishments during 1978

Two small areas of middle Paleozoic limestone were discovered near Gertrude Creek, 16 km north of Becharof Lake on the Alaska Peninsula, during reconnaissance flying as part of the Alaska Mineral Resource Assessment Program (AMRAP) for the Alaska Peninsula. Previously, the only known occurrence of Paleozoic rocks on the Alaska Peninsula was a...

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...

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...
