Abstract
BOSTON-- The annual meeting of the American Association for the Advancement of Science (publisher of Science), held from 15 to 19 February, included symposia across the scientific disciplines. At one presentation, a researcher suggested that whaling decades ago may have triggered a cascade of ecological events that ultimately wiped out kelp forests off Alaska9s coast. This story and the previous one are a sampling from the early sessions; more coverage will be published next week.
