Multi-locus coalescent-based analyses of population divergence (IMa2). Marginal posterior density distributions from IMa2 analyses – seven independent MCMC analyses (M-mode) of DNA sequence data from one mitochondrial locus and 11 nuclear loci for the divergence of C. clarum and C. castanotum from their common ancestor. On a demographic scale, parameters are (a) time since divergence in years; b effective population size, Ne; and c effective number of migrants per generation, 2 Nm
