Causes and consequences of marine mammal population declines in southwest Alaska: a food-web perspective.
Populations of sea otters, seals and sea lions have collapsed across much of southwest Alaska over the past several decades. The sea otter decline set off a trophic cascade in which the coastal marine ecosystem underwent a phase shift from kelp forests to deforested sea urchin barrens. This interaction in turn affected the distribution, abundance and productivity of numerous other species. Ecol...

During 1985-1990, two groups of killer whales in Prince William Sound, Alaska, experienced unusually high rates of mortality, while seven others did not. Those affected were AB pod, part of the southern Alaska population of resident (fish-eating) killer whales, and the AT1 transient (marine mammal-eating) group, a very small, reproductively isolated population that last reproduced in 1984. In 1...
متن کاملTrend data do support the sequential nature of pinniped and sea otter declines in the North Pacific Ocean, but does it really matter?
The Sequential Megafaunal Collapse Hypothesis (SMCH) posits that decimation of great whales in the North Pacific Ocean in the 1950s and 1960s, by Russia and Japan following the end of World War II, removed an important source of prey for marine mammal eating killer whales in southwest Alaska (the Aleutian Islands, southern Bering Sea, and western and central Gulf of Alaska). The killer whales s...
