Population genetic structure of roseate tern (Sterna dougallii) populations in Australia and surrounding regions and a preliminary investigation of the relationships among subspecies (C1.4.2.1S)

Task leader: Ms Anna Lashko, CRC Reef and James Cook University.

Task associate: Mr Malcolm Turner, Marine Parks Management Coordination.

The overall aim of this project is to examine population genetic structure in roseate terns on a variety of spatial scales: local (within and among island groups in the Great Barrier Reef), regional (Australia-wide) and global. I will be examining the relationships among breeding populations, and also the relationships between breeding and non-breeding groups of roseate terns.

To do this I will be using both microsatellite and mtDNA markers. I am currently developing microsatellite markers for the roseate tern, as no such markers have been published for any tern species. I am also in the process of developing primers to amplify the mitochondrial control region of the roseate tern using DNA from a number of species in the genus Sterna to ensure maximal usage for future studies.
