Fluctuations in the Bering Sea ecosystem as reflected in the reproductive ecology and diets of kittiwakes on the Pribilof Islands, 1975 to 1991
In the SE Bering Sea, sea surface temperatures increased from the late 1970s to the mid-1980s, then decreased. Over the same period, there were inter-annual variations in the water masses surrounding the Pribilof Islands. Subsequent to the mid-1970s, there were changes in the abundance of capelin Ma...
