Abstract

Naturally occurring genetic diversity is the material upon which much of the biodiversity we attribute to forested ecosystems is based. The structuring of genetic diversity within natural populations of forest trees results from the interplay of numerous evolutionary forces, such as genetic drift, migration, and natural selection. Landscape genomics is concerned with testing hypotheses about how these interacting evolutionary forces change over geographical space and time to shape naturally occurring patterns of this diversity. Here, I will use a landscape genomic approach to illustrate how genetic drift, migration, and natural selection interact to determine patterns of genetic diversity, including the genetic diversity underlying fitness-related phenotypes, at multiple spatial scales within natural populations of forest trees.
