Stable isotopes of Mya arenaria during 2010 and 2011 to determine food sources

Several sites in Plum Island Sound, the mainstem of the Parker River and Rowley River were selected and sampled during 2010 and 2011 for 2 and 4 inch intertidal clams on a monthly basis. The tissue of these clams were analyzed for stable isotopes to determine the food source of these clams. Water samples were also filtered and plants were collected to determine their isotopic composition as well.

本研究于2010年至2011年间，在普卢姆岛海峡（Plum Island Sound）、帕克河（Parker River）与罗利河（Rowley River）的干流区域选取多个采样点位，按月对体长2英寸及4英寸的潮间带蛤蜊进行采样。随后对采集到的蛤蜊软组织开展稳定同位素分析，以确定该类蛤蜊的食物来源。同时对水体样本进行过滤处理，并采集水生植物样本以测定其同位素组成。
