Drew Harvell, professor emerita of marine ecology, pauses to admire eelgrass, a cold water species of seagrass, at low tide in False Bay, San Juan Island, Washington.

News

Cornell plant and computer science experts joined forces to show how herbivores like sea snails can promote the spread of seagrass wasting disease. Grazing by small herbivores was associated with a 29% increase in the prevalence of disease.
