Investigating the interaction between species nesting sympatrically in the vicinity of polynyas should provide insights into the role that such oceanographic features play for pre-breeding seabirds. We used stable isotopes (δ<sup>13</sup>C and δ<sup>15</sup>N) to compare the diet of two g ...[more]
