Concordance Between Phylogeographic and Biogeographic Boundaries in the Coral Triangle: Conservation Implications Based on Comparative Analyses of Multiple Giant Clam Species

摘要: Marine habitats are in decline worldwide, precipitating a strong interest marine conservation. The use of biogeographic data to designate ecoregions has had significant impacts on terrestrial conservation efforts. However, classification environments into only become available the last several years, based supplemented by geomorphology, ocean currents, and water temperatures. Here we comparative phylogeographic approach test for concordant patterns three closely related species Tridacna giant clams across Coral Triangle, most biodiverse region world one threatened. Data from 450 base pair fragment mitochondrial cytochrome-c oxidase subunit DNA 1739 Indonesia Philippines show concordance between as well evidence potentially undescribed within genus. Phylogeographic correspond broadly proposed Spalding et al. (2007), indicating that processes contributing boundaries likely also limit genetic connectivity this region. These can assist with designing more effective networks protected areas ensuring unique regions represented regional planning.
