Population structure, Pocillopora damicornis, Mexican Pacific, population genetics
"Genetic structure was studied in the coral Pocillopora damicornis in three areas of coral development of the Mexican Pacific (MP). Specimens were collected from six localities: El Portugues and Punta Gaviotas located inside the Gulf of California (GC), Punta Arenas and Isla Redonda from the entrance of GC, and Las Dos Hermanas and La Entrega in the south of the MP. Exclusive genotypes were observed in the northern and southern populations. Genetic variation was similar along the MP, although slight higher variation was observed in the southern populations. Most of the populations presented significant deficits heterozygotes. These deficiencies could be due to the predominance of the asexual reproduction by fragmentation, localized sexual reproduction, inbreeding and/or Wahlund effect among localities, and different mortality events by natural disturbances. Cluster analysis based on genetic distance showed three groups by geographical proximity: two populations inside the GC, those ones located in the entrance of the GC, and two populations located at the south of the MP. Mean significant FST value (FST = 0.153) indicated a genetic structure. Differences in sexual and asexual reproduction among the localities coupled with local recruitment and currents patterns are possibly generating the genetic structure observed in the populations of P. damicornis in the MP."
