Abstract
Samples representing the damselfishes (Perciformes: Pomacentridae) Stegastes nigricans, Chrysiptera biocellata, C. glauca, and C. leucopoma from North Male Atoll, Republic of Maldives, and Guam, Southern Marianas, were surveyed electrophoretically. A sample representing C. leucopoma from Ngemelis Island, Republic of Palau, was included in the analysis to provide a within-Micronesia comparison. On average, products of 23 presumptive protein-coding loci were examined in each sample. In comparisons of Maldivian and Guamanian samples, absolute or virtually fixed allelic differences were detected at: (1) ADA * and PEPS * for Stegastes nigricans; (2) ADA *, AAT-1 *, AAT-2 *, and mMDH * for C. biocellata, and; (3) ADA *, AAT-1 *, and AAT-2 * for C. glauca. At three polymorphic loci, ADA *, sMDH-1 *, and sMDH-2 *, similar allele frequencies were found in Palauan and Guamanian samples representing C. leucopoma, suggesting that these samples share a gene pool. Significantly different allele frequencies at ADA * and sMDH-1 * and a virtually fixed allelic difference at sMDH-2 * were detected between the Maldivian samples and each of the Micronesian samples representing C. leucopoma. The observed patterns of allele frequency differentiation suggest that Maldivian and Micronesian samples of each of the four study species represent separate demes.
