Abstract

Landscape genetics investigates relationships between population processes and landscape structure. I use this approach to understand the role of specific landscape features and environmental conditions in affecting population connectivity, gene flow and movements of a threatened species. The Black-throated Finch, both northern (Poephila cincta atropygialis) and southern subspecies (P. c. cincta), has subjected to many threatening processes over the last decade, especially the southern form. The decline of P. c. cincta is believed to be primarily due to overgrazing of riparian grassland, clearing and habitat fragmentation. The genetic consequence of the decline is unknown. I use molecular data to identify population structure; to quantify gene flow between remnant populations; and to understand how these dynamics are related to landscape features. With the analysis of landscape genetics, I can understand the extent of genetic impacts from environmental disturbance, the way in which birds use landscapes, and how viable and differentiate the existing populations are.
