  1. Θ (Effective population size [Ne] * mutation rate [μ]), migration rates (M), and number of effective migrants per generation (Nem) among six populations along the Northeast Australian coast and Papua New Guinea (PNG), as estimated by MIGRATE. Populations were: N'GBR (Northern Great Barrier Reef [GBR]); Cen. GBR (Central GBR); Cap. GBR (Capricorn Section GBR); BNE (Sunshine Coast & Brisbane); Coral Sea (Osprey, Bougainville and Holmes Reefs); and PNG (Papua New Guinea). For immigration occurring between populations, the upper row is the receiving population and the left column is the broadcasting population. Θ values are given in the diagonal. The first number in the other cells is Nem, derived by calculating (Θ * M)/4, and the numbers in parentheses are migration rates (M). The numbers of alleles used were (ATPSb-iII/ITS) for N'GBR: 22/23; Cen. GBR: 18/16; Cap. GBR: 42/33; BNE: 16/8; Coral Sea: 26/27; and PNG: 28/20, for a total of 152/127.
