Fig.1. Map of population localities around the island of Bangkulu, Banggai Archipelago, Indonesia. Allele frequency pie charts for locus Pka6 (left panel) and Pka 11 (right panel). Each
individual color represents an allele at the appropriate locus and the percent of the pie chart displaying that colour represents the frequency of that allele in the population. A
coastline highlighted in green on the map of the island indicates the presence of Pterapogon kauderni, absence of the specie is indicated in red, and the regions that were not surveyed
are in black. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
