Abstract
The Black-throated Finch (Southern) (Poephila cincta cincta) is threatened by the substantial landscape changes in northern Australia. We developed 16 polymorphic microsatellite markers using 454-shotgun whole-genome sequencing technology. We identified an average of 4.7 alleles per locus based on 63 wild caught individuals from Townsville, Queensland. Thirteen and 9 markers were also successfully cross-amplified in two confamilial species, the Double-barred Finch (Taeniopygia bichenovii) and the chestnut-breasted Mannikin (Lonchura castaneothorax) with 11 and 5 were polymorphic, respectively. These markers will help understand the population genetic structure of the endangered Black-throated Finch and determine genetic consequences of landscape changes for the species.
