Rising seas, peat may have done in large ice age animals

ANCHORAGE - Woolly mammoths and other large ice age mammals thrived in northern Alaska until environmental changes turned grasslands into peat and rising sea levels submerged the Bering Land Bridge, cutting off their access to Asia, according to a research paper published Monday.Researchers from the University of Alaska Fairbanks and the University of California studied bones of ice age horses, steppe bison, mammoths and other animals to determine why they died out in what's now Arctic Alaska.

Did whaling cause decline in sea otters?

A cascading decline in seal, sea lion and sea otter populations in the North Pacific may have been triggered by industrial whaling after World War II that forced packs of killer whales to look for new sources of food, a group of scientists suggest. "If our hypothesis is correct, either wholly or in significant part, commercial whaling in the North Pacific Ocean set off one of the largest and most complex ecological chain reactions ever described," the scientists wrote in an article appearing this week on the Proceedings of the National Academy of Sciences Web site.
