Landscape genetics explores how the microevolutionary processes of gene flow, genetic drift, and natural selection interact with environmental heterogeneity to shape population genetic structure. This chapter begins with a review of the various types of genetic data used in population and landscape genetics and discusses how these data are used to estimate genetic variation (heterozygosity) and gene flow among populations. From there, the chapter considers how population genetic structure can be assayed, which then segues into an analysis of the landscape correlates of population genetic structure, the identification of movement corridors and barriers to gene flow, and the relative effects of current versus historical landscape factors on population genetic structure. The chapter concludes with an overview of evolutionary landscape genetics, by considering the adaptive potential of populations in response to future landscape and climatic changes.
