Working on a lobster boat in Swan's Island, Maine, typically means an early wake-up call. The boats head out around 5:30 in the morning. For University of Pennsylvania ecologist Peter Petraitis, California State Northridge biologist Steve Dudgeon and their team, it's not much later when they head out as well. But they're used to it. Petraitis and Dudgeon, along with Cheverus High School teacher Erika Rhile and her students, have been returning to this rocky intertidal zone every spring and summer for nearly two decades!
