They’re lovingly called "sea squirts," but these marine soft-bodied animals, or tunicates, could cause a giant-sized problem in cold water areas like the Gulf of Maine. New UNH research indicates that with a water temperature increase of two degrees Celsius (or 3.6 degrees Fahrenheit) predicted in the coming years, the invasive tunicate species Botrylloides violaceus will be able to double its reproduction rates in places like Portsmouth Harbor, in Portsmouth, New Hampshire, and in Eastport, Maine. This seemingly modest increase will allow B. violaceus to occupy even more space on natural and artificial surfaces, crowding out native species and potentially creating problems for aquaculturists who work along the northern New England coast. “We’ve seen their populations spread northeastward...
