Deep-sea clams feel the heat

Article Abstract:

Fujiwara and colleagues have documented a project to study giant white clams at depths of more than 1,100 m below the surface of the sea. They have provided evidence for the hypothesis that the clams respond reproductively to small increases in water temperature. The giant white clams of Sagami Bay, Japan thrive in dense populations, and they were studied over an 18-month period. Deep sea was previously regarded as an unchanging environment, and there was not thought to be any periodicity in the reproductive activity of deep-sea organisms.

Burrowing saves Lake Erie clams

Article Abstract:

A large population of native clams has been discovered in a Lake Erie wetland that shows few signs of infestation by zebra mussels. It was found that the clams burrow due to the warm summer water temperatures and the soft sediments, which in turn discourages infestation by zebra mussels. The area was invaded by zebra mussels around 1990 and near total mortality was reported in western Lake Erie.
