Previous phylogeographic studies of the humbug damselfish, a widespread Indo-West Pacific coral reef fish, have revealed a split of two main mitochondrial lineages distributed on either side of the Indo-Pacific barrier. This has been interpreted as the result of vicariance. It has been hypothesized that reproductive barriers might currently limit gene flow between humbug damselfish populations from the Indian Ocean and the Pacific Ocean. In this study, we review the published phylogeographic information to update the distribution of the two main mitochondrial lineages of humbug damselfish. The Indian lineage was distributed from the Red Sea to the eastern extremity of the Sunda Shelf while the Pacific lineage, which diverged from the former by 0.6% net nucleotide divergence and diagnostic substitutions at three nucleotide sites at the cytochrome b locus, was distributed east and north of the Sunda Shelf. The two forms, which are also genetically distinct at nuclear loci, were also characterized by distinct pigmentation patterns. We argue that the two forms represent geminate species. Epithet aruanus Linnaeus is maintained for the Pacific Ocean humbug damselfish while epithet abudafur (Forsskål. ) is here resurrected for the Indian Ocean humbug damselfish. Future studies should focus on the population genetic structure of the transition zone between Dascyllus abudafur and D. . © 2014 Acade´mie des sciences. Source

Sharks are one of main fisheries commodity that are currently exploited on a large scale because of their high economic value. The identification of sharks has been a difficult one due to the specimen’s similarity in morphology and mostly have had key diagnostic features removed. This study aimed to identify and to review the status of sharks, and also to reconstruct the shark species that were landed at South Java fishing port using molecular approaches. The DNA amplification was using cytochrome oxidase I mitochondrial of locus and 600-700 basepairs. A total of seven species from 59 individuals was identified including Alopias pelagicus, Carcharhinus falciformis, C. sorrah, C. amblyrhynchos, Galeocardo Cuvier, Atelomycterus marmoratus, and Spyrna lewini. The diversity of shark species landed in Muncar during the last 2 years has been decreased. The identified sharks species in this study sites were about 18% of all Indonesian sharks. The result of this study is expected help the Government to manage shark fisheries in Indonesia. © 2015, Society for Indonesian Biodiversity. All rights reserved. Source
