Lanscape Genetics

Presented by Landscape genetics rests at the interface of landscape ecology and population genetics, and seeks to understand how real space and associated landscape features affect connectivity between populations. The relatively novel method used in this field have been applied to several endangered species to investigate possible impacts of land-use change, environmental change and to propose corridors for potential movement. In this short workshop we will start by laying out the basics of the study of dispersal and geneflow, followed by simple population genetics of how gene flow (or lack thereof) results in similarities/differences between populations. We will use an exercise-based approach, and students will work in groups to understand the effects of landscape given a putative species, simulated genetic data, and a possible landscape. Groups will work towards investigating what may cause barriers to animal movement, and explore the concept of resistance. We will discuss least cost path calculation, as well as resistance-based approaches, moving towards causal models for genetic connectivity.
