Molecular Identification and Genetic Diversity of Acropora hyacinthus from Boo and Deer Island, Raja Ampat, West Papua
2018
Indonesia lies at the centre of biodiversity for corals. However, the reefs suffered from
extensive human exploitation. Marine Protected Areas is thought to be best solution to protect
coral reefs ecosystem. Understanding genetic diversity is crucial for effective management of the
MPAs, however genetic diversity is rarely been corporate in designing an MPA. Moreover, many
MPAs are uneffectively manage due to poor designated and demarcated.Raja Ampat which is
located in western tip of West Papua, was designated as a park to mitigatethreatsand protect the
valuable marine resources.Scleractinian corals in the genus Acropora are among the most
dominant distributed in Raja Ampat waters, including the species of Acroporahyacinthus.The
research aimed to analyze genetic diversity and to describe the kinship relationship of
Acroporahyacinthus between 2 populations: Boo Island and Deer Island, Raja Ampat. Genetic
marker Cytochrome Oxidase I (CO I) of the mitochondrial genome DNA (mtDNA) was used to
analyze genetic diversity. Reconstruction of phylogenetic tree and genetic diversity were made
by usingsoftware MEGA 5.05 (Moleculer Evolutionary Genetics Analysis). The results of this
research indicatecorals A. hyacinthus from Boo Island and Deer Island Raja Ampat are in the
low category of genetic diversity and overall had 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.
