Table 1.
Mixed stock analysis (MSA) using ‘many-to-many’ model. The proportion of stranded juveniles in the Bay of Biscay originating from the different rookeries is estimated using foraging ground centric analysis, computed with and without population size information. The proportion of individuals from each rookery that ends up stranded in the Bay of Biscay is estimated with rookery-centric analysis. The latter excluded Mediterranean rookeries since foraging ground centric analysis showed little contribution from these populations. Mean and standard deviation (s.d.) values are shown. Br, Brazil; ES-RJ, Espírito Santo-Rio de Janeiro. Further details of datasets used in the MSA are in the electronic supplementary material, tables S1 and S2.
