戴昌鳳老師與劉商隱博士研究焦點：珊瑚大三角的物種起源與隱蔽種

珊瑚大三角是全球海洋生物多樣性中心，它的形成機制至今未明。本所劉商隱博士與其指導教授戴昌鳳以微衛星DNA及粒線體DNA為分子標誌，分析印度太平洋的霓虹雀鯛(Pomacentruscoelestis)族群之親緣地理結構，探討其物種起源的機制。The Coral Triangle is known as marine biodiversity center according to its highestmarine biodiversity.However, the mechanism to form such a high biodiversity is still under debate. Pomacentruscoelestisis also known as neon damselfish which distributed across coral triangle has been used as a model species to reveal its phylogeographic structure and test different hypotheses of the process how marine biodiversity center was formed. The results indicated Center of Origin and Center of Overlap are both present in P. coelestis, and suggest that multiple evolutionary processes may have acted on single species, either simultaneously or at different times,and have important implications for reef fish management in the West Pacific.This project is under an international collaboration with Dr. Gerald Allen (Western Australian Museum) and Dr. Mark Erdmann (Conservation International), and this finding has been published in Marine Ecological Progress Series vol. 458, pages 155-167 (2012). In addition, a cryptic species distributed mainly in Micronesia,hasbeen described as a new species and accepted by Zoological Studies already.

結果發現種源中心說與重疊中心說皆符合霓虹雀鯛之族群特徵，表示珊瑚礁魚類的起源可能受到多重機制的影響，此報導已發表於2012年7月的Marine Ecology Progress Series 上。另外，此研究發現一分佈局限於密克羅西亞的隱蔽種(P. micronesicus)，已被Zoological Studies接受發表。
