Collecting Trip

WHOI biologist Ann Tarrant collects animals from a Woods Hole, Mass., salt marsh to culture and study in the lab. Tarrant investigates the genes invertebrate animals use to respond to environmental factors or pollutants, or when their activities show signs of a circadian rhythm or ‘internal clock,’ to better understand basic questions about how these systems evolved and persisted in animals. She has also mentored postdoctoral scientists and MIT-WHOI Joint Program student Amalia Aruda, who studied bacterial communities living on shrimp-like invertebrates called copepods.
