Table 1. Population genetic summary and demographic statistics for Victoria Land Coast (VLC) and Macquarie (MQ) populations.

	N	S	h	Hd	k	S/k	Fs	D	BF

P values were obtained with 50,000 coalescent simulations. N: number of individuals; S: segregating sites, h: number of haplotypes; Hd: haplotype diversity (±s.d.); k: average number of nucleotide differences; S/k: ratio of S over k; Fs: Fu's Fs; D: Tajima's D; BF, approximate Bayes Factor selection of alternative demographic models (constant vs. exponential), using the difference in harmonic means of sampled marginal likelihoods implemented in BEAST [58]. * indicates 3<BF(±s.e.)<10.
