Abstract
Landscape genetics emerged in 2003 as a field that integrates population genetics, landscape ecology and spatial statistics to evaluate the influence of landscape characteristics on the spatial distribution of genetic variation. Over the past 20 years, interest in the field has burgeoned, resulting in an increasing number of published studies and subdisciplines within the field. For example, current landscape genetics research includes riverscape genetics, seascape genetics, adaptive landscape genomics, landscape community genomics and landscape epigenetics. Given that the field has already been reviewed multiple times, the goal of this article is to focus on key areas, including: (1) emphasizing the importance of a robust study design; (2) discussing the most prevalent analytical frameworks; (3) summarizing major insights; and, (4) highlighting future directions.
