1. How similar are CEMP indices from adjacent locations? A case of study using Pygoscelis adeliae and P. papua monitoring data from three breeding colonies on King George Island

   Abstract:  What is the spatial scale of monitoring conducted at an individual CCAMLR Ecosystem ... species that are monitored at three sites on King George Island/Isla 25 de Mayo, within 30km of one ... another. We used five indices that fall under three main categories of census (breeders and chicks ... found evidence of and site- and species-specific differences that highlight heterogeneity in indices of ...
