Table 2. Pairwise population divergence modeling.

Pairwise IMa2 population estimates of current (N ₁ and N ₂) and ancestral (N_A) effective population size, population migration rates (2N ₁m_1>2 and 2N ₂m_2>1) moving forward in time, and divergence time in years (T, with highest posterior density or HPD) for all multilocus samples.
