Warm waters may muscle out mussels
Warming waters make it harder for mussels to get a grip. New research shows that the tough, fibrous threads that anchor the bay mussel Mytilus trossulus to its rocky intertidal digs are 60 percent weaker in 25° Celsius waters compared with their strength at 18° C, reported Emily Carrington of the University of Washington Friday Harbor Laboratories. Mussels are constantly replenishing these fibers, which last about two months in winter and up to a month in summer. As the oceans warm, the range of the species may shift, or perhaps having weaker threads may mean that other species will muscle in on mussel territory, Carrington said February 16. — Rachel Ehrenberg
