【 摘 要 】

Karimunjawa is one of the earliest marine parks in Indonesia. Karimunjawa National Park (KNP) was designated as a marine conservation area to conserve marine resources from destructive fishing activities. Scleractinian corals in the genus Acropora are among the most dominant distributed in the KNPs, including the species of Acropora hyacinthus. Here, we present a comprehensive analysis of intra- and interspecific COI variabilities in A. hyacinthus to analyze genetic diversity and to describe the kinship relationship of the coral between 5 localities of the reefs. Genetic marker Cytochrome Oxidase I of the mitochondrial genome DNA (mtDNA) was used to analyze genetic diversity. Reconstruction of phylogenetic tree and genetic diversity were made by using software MEGA 5.05 (Molecular Evolutionary Genetics Analysis). The results indicate corals A. hyacinthus from five localities of Karimunjawa Archipelago are in the high category of genetic diversity. However, the five populations showed a close genetic relationship of kinship. This is likely due to the small size of the population and few numbers of samples that may not represent the population. The results may aid managers of the park in the selection of appropriate propagules sources which can help to restore important data for conservation and sustain coral reef resources.
