Results of the pairwise mismatch distribution analyses. Results are shown using all mtDNA haplotypes from each lake in pooled samples. Observed pairwise differences are shown by the solid line, the distribution under a model of sudden population expansion is shown as a dashed line, and the 95% confidence intervals are shown as gray dotted lines. (A) Lake Apoyo is primarily unimodal, with a small peak at 0 pairwise differences and cannot be distinguished from the distribution under a sudden expansion model. (B) Lake Xiloa is distinctly unimodal and cannot be distinguished from the distribution under a model of sudden population expansion. (C) Lake Masaya is apparently unimodal, though the peak is skewed to a higher pairwise difference than expected under model of sudden population expansion, from which it cannot be distinguished. (D) Lake Nicaragua is multimodal, though it cannot be distinguished from the distribution under a model of sudden population expansion.
