Increases in jellyfish biomass in the Bering Sea: implications for the ecosystem
There has been a dramatic increase in jellyfish biomass over the eastern Bering Sea shelf since the early 1990s, which was previously hypothesized to have been triggered by changing climate and oceanExpand

Resource allocation in breeding seabirds: responses to fluctuations in their food supply
In the vicinity of the Pribilof Islands in the Bering Sea, abundance of food available to surface-foraging seabirds was greater during the chick-rearing period in 1988 than in 1987, whereas abundanceExpand

Patterns in prey use among fur seals and seabirds in the Pribilof Islands
Abstract We explored correlation in diet trends for five piscivorous predators that reproduce on the Pribilof Islands as illustrative of the shifting structure of the Bering Sea ecosystem. WeExpand

Trends in carbon flux to seabirds in the Peruvian upwelling system: effects of wind and fisheries on population regulation
We hypothesized that change in the annual population size of guano-producing seabirds (cormorant, Phalacrocorax bougainvillii; booby, Sula variegata; pelican, Pelecanus thagus) is a response toExpand

Rise and fall of jellyfish in the eastern Bering Sea in relation to climate regime shifts
A steep increase in jellyfish biomass, primarily Chrysaora melanaster, over the eastern Bering Sea shelf was documented throughout the 1990s. Their biomass peaked in summer 2000 and then declinedExpand

Brood Reduction in Black-Legged Kittiwakes
ln 1978 and 1979 we studied brood reduction in Black-legged Kittiwakes (Rissa tridactyla) on St. Paul Island, Alaska. In two-egg clutches, first-Laid eggs were larg.est; they were incubated beforeExpand

Foraging ecology of short-tailed shearwaters near the Pribilof Islands, Bering Sea
We studied short-tailed shearwaters Puffinus tenuirostris foraging near the Pribilof Islands, Alaska, USA, during the summers of 1987, 1988, and 1989. Their foods were almost exclusively theExpand
