We would like to use the information of mitochondrial DNA (mtDNA) and nuclear DNA to study the genetic diversity of finless porpoise (Neophocana phocaenoides),bottlenose dolphin (Tursiops spp.) and Indo-Pacific humpback dolphin(Sousa chinensis) in Taiwan Strait. In this proposal, we will conduct the mtDNA database including control region and cytochrome b fragments of the finless porpoise in first year. Microsatellite DNA library of finless porpoise will also be built. The population genetic diversity of bottlenose dolphin and Indo-Pacific humpback dolphin in Taiwan strait will be estimated in fututre study. The population differentiation of the conspecific dolphin in Taiwan Strait and adjacent waters will also be studied.鯨豚台灣海峽遺傳多樣性核DNA粒線體DNAcetaceansTaiwan Straitgenetic diversitynuclear DNAmitochondrial DNA
