Testing for individual variation in breeding success Testing for individual variation in breeding success

I measured the breeding success of Northern Fulmars (Fulmarus glacialis) in 6 consecutive years at a colony in the Semidi Islands, western Gulf of Alaska (56°N, 156°W). I tabulated the frequency distribution of the number of years successful for a sample of 224 nest sites at which breeding occurred in all 6 yr. A consistently higher probability of success occurred in some sites than in...

Foraging by northern fulmars (Fulmarus glacialis) at a nearshore, anticyclonic tidal eddy in the northern Bering Sea, Alaska Foraging by northern fulmars (Fulmarus glacialis) at a nearshore, anticyclonic tidal eddy in the northern Bering Sea, Alaska

Northern Fulmars (Fulmar glacialis) fed on ice-associated macrofauna (probably gammarid amphipods) and pinniped offal concentrated by convergent flow at an eddy boundary near Northwest Cape on St. Lawrence Island, Alaska. The eddy was anticyclonic, measured approximately 1.5 by 2.25 km, and was generated by nearshore streaming induced by the cape’s topography during lesser flood stage of...

Geologic studies in Alaska by the U.S. Geological Survey during 1987 Geologic studies in Alaska by the U.S. Geological Survey during 1987

This volume is a continuation of the annual United States Geological Survey (USGS) Circulars reporting results of work in progress on earth science investigations in Alaska. The series began in 1975 under the title "The United States Geological Survey in Alaska - Accomplishments during 19xx" and has continued since 1986 under the present title. The 40 short papers and the feature article...

Populations, productivity, and feeding habits of seabirds on St. Lawrence Island, Alaska: Final report Populations, productivity, and feeding habits of seabirds on St. Lawrence Island, Alaska: Final report

A field camp was established at Kongkok Bay near the southwest cape of St. Lawrence Island and occupied continuously from 24 May to 2 September 1987. Permanent study plots were selected for both cliff and crevice-nesting species, and regular observations were made throughout the breeding season to document attendance patterns, breeding phenology, and success. Periodic collections of...

Polar Bear Polar Bear

Polar bears are long-lived, late-maturing carnivores that have relatively low rates of reproduction and natural mortality. Their populations are susceptible to disturbance from human activities, such as the exploration and development of mineral resources or hunting. Polar bear populations have been an important renewable resource available to coastal communities throughout the Arctic...

Seasonal occurrence of migrant whimbrels and bristle-thighed curlews on the Yukon-Kuskokwim Delta, Alaska Seasonal occurrence of migrant whimbrels and bristle-thighed curlews on the Yukon-Kuskokwim Delta, Alaska

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...

Effects of the 1982-83 El Niño – Southern Oscillation on Pacific Ocean bird populations Effects of the 1982-83 El Niño – Southern Oscillation on Pacific Ocean bird populations

Seabird reproductive success, population size, and movements in the Pacific region responded dramatically to the 1982-83 El Niño – Southern Oscillation (ENSO). At sites within the North and South Pacific Gyres, the onset of seabird responses tracked oceanographic changes related to ENSO; to the north of the gyres, responses were delayed 1 yr. Reproductive failures and high adult...

Brief descriptions of mines, prospects, and mineral occurrences in the Port Moller and Stepovak Bay quadrangles, Alaska peninsula Brief descriptions of mines, prospects, and mineral occurrences in the Port Moller and Stepovak Bay quadrangles, Alaska peninsula

This report contains brief descriptions of known mines, prospects, and mineral occurrences in the Port Moller and Stepovak Bay quadrangles on the Alaska Peninsula. These quadrangles, and the adjoining Simeonof Island quadrangle to the south were the subject of an Alaska Mineral Resource Assessment Program (AMRAP) mapping and mineral resource assessment project. This compilation of...

Interactions between seabirds and fisheries in the North Pacific Ocean Interactions between seabirds and fisheries in the North Pacific Ocean

Interactions between commercial fisheries and seabirds in the northern Pacific Ocean are increasing with rising consumption of fishery products. As fishing expands into remote areas previously not fished, additional populations of seabirds may be affected. Some interactions such as introduction of fish processing wastes into the environment may be beneficial for seabirds, while others...
