Mismatch distribution for Cephalopholis argus. Mismatch distribution based on 550 cytochrome b sequences from twenty-one populations. The dark colored line represents the observed and light colored line is the simulated pairwise differences as reported by DnaSP 5.0 [39]. The Harpending's raggedness index as calculated in ARLEQUIN 3.5 [42] and corresponding P-value are shown.

Median-joining networks for Cephalopholis argus. Networks were constructed using the program NETWORK 4.5 [43] for (a) 550 cytochrome b sequences (b) alleles at GnRH intron from 488 individuals, and (c) alleles at S7 intron for 490 individuals. Each circle represents one mitochondrial haplotype or nuclear allele with the area of each circle proportional to the number of that particular haplotype or allele in the dataset; dashes represent hypothetical haplotypes or alleles; colors represent collection location (see key).

Figure 3. From: Phylogeography of the reef fish Cephalopholis argus (Epinephelidae) indicates Pleistocene isolation across the indo-pacific barrier with contemporary overlap in the coral triangle.

Phylogenetic tree of Cephalopholis argus cytochrome b haplotypes. The best maximum likelihood tree generated using program default settings in RAxML [44] and rooted using two congenerics (C. urodeta and C. taeniops). Bootstrap support values were calculated using default settings with 1000 replicates. For comparison neighbor-joining bootstrap values (1000 bootstrap replicates) and Bayesian posterior probabilities are presented. Colored bars delineate the Pacific and Indian Ocean lineages separated by three fixed differences (see figure 1).

Migration rates for Cephalopholis argus. Migration rates (Nm: where N is effective female population size and m is migration rate) based on cytochrome b sequences calculated using MIGRATE 3.1.6 [54,55]. Locations with non-significant pairwise ΦST values were grouped (see Table 2). French Polynesia (FP) = Marquesas and Moorea; central-west Pacific (CW) = Kiritimati, Palmyra, Samoa/Tokelau, Baker/Howland, Kwajalein, Pohnpei, Saipan, Palau, Lizard Island, Philippines, and Scott Reef; Indo-Pacific boundary (IB) = Bali and Rowley Shoals; eastern Indian Ocean (EI) = Christmas Island and Cocos/Keeling; western Indian Ocean (WI) = Sumatra, Diego Garcia, Oman, and Seychelles. The direction of migration is indicated. Numbers of migrants per generation between geographic regions are reported with 95% confidence intervals in parentheses.
