Fig. 1
Patterns of genetic diversity and bottleneck signatures across the pinnipeds. The phylogeny shows 30 species with branches colour coded according to breeding habitat and tip points coloured and sized according to their IUCN status and global abundance respectively. a Shows two genetic diversity measures, allelic richness (Ar) and observed heterozygosity (Ho), which have been standardised by randomly sub-sampling ten individuals from each dataset 1000 times with replacement and calculating the corresponding mean. b Shows the proportion of loci in heterozygosity-excess (prophet-exc) calculated for the TPM80 model (see Methods for details). c Summarises the ABC model selection results, with posterior probabilities corresponding to the bottleneck versus non-bottleneck model. The raw data are provided in Supplementary Tables 2 and 3
