ELLSWORTH — Downeast Audubon will present “Shells: Treasures from Maine Shores” 7 p.m. Monday, Oct. 21, at Moore Community Center, State Street.
Alison C. Dibble, Ph.D., retired conservation biologist of Brooklin, will share her passion for Maine shells ranging from clams and snails to slippers and whelks. The diversity of marine mollusks in the Gulf of Maine has changed over thousands of years. Ancient shells might be found next to contemporary shells on the same beach. We will cover some challenges to mollusk conservation in a changing climate. Bring 1-2 of your favorite shells or an unknown (from Maine shores only) for us to ponder together.
