Table 3 Estimates of onset of splitting time (t) across the two detected genetic discontinuities (30° and 35°S) and migration rates (m) from North to South (N > S) and S to N (S > N) for COI sequences of Excirolana hirsuticauda based on the isolation-with-migration model implemented in IMa2

From: Genetic and morphological divergence at a biogeographic break in the beach-dwelling brooder Excirolana hirsuticauda Menzies (Crustacea, Peracarida)
