Here the population genetic structure of an ecologically and economically important coral reef fish, the coral trout Plectropomus leopardus, is investigated in the context of contemporary and historical events. Coral trout were sampled from four regions (six locations)
and partial mtDNA D-loop sequences identified six populations (Fst = 0.89209, P < 0.0001): Scott Reef and the Abrolhos Islands in west Australia; the Great Barrier Reef (GBR), represented by northern and
southern GBR samples; New Caledonia and Taiwan, with Taiwan containing two genetic lineages. Furthermore, this study identified
source and sink populations within and among regions. Specifically, the northern population in west Australia (Scott Reef)
was identified, as the source for replenishment of the Abrolhos population, whilst New Caledonia was a source for recruitment
to the GBR. Based on these insights from a single mtDNA marker, this study will facilitate the development of rational management
plans for the conservation of P. leopardus populations and therefore mitigate the risk of population declines from anthropogenic influences. 相似文献
