Abstract

Information on the extent of genetic differentiation among seabird populations is essential for conservation planning. Here we used, for the first time in little penguins (Eudyptula minor), a next generation sequencing approach to investigate population genetic structure, gene flow and inbreeding among eight colonies in South Australia. We found that Troubridge Island individuals were genetically distinct from the other sampled colonies, and that colonies on all islands were connected by moderate levels of gene flow possibly due to migration from the Kangaroo Island colonies. While further genetic sampling is needed, these data support the idea that South Australia may be a zone of subtle and rapid genetic change for little penguins.
