Landscape genetics of ungulates

Full title:

Using comparative landscape genetics to assess connectivity in fragmented landscapes and identify functional ecological networks

Abstract

Habitat fragmentation has been recognised as one of the key threats to wildlife worldwide. Protected areas are usually considered to be the cornerstone of biological conservation as they are expected to represent the best areas available to ensure the persistence of biodiversity and thereby counteract the negative effects of fragmentation and habitat loss. However, existing protected areas, particularly in Europe, are often too small to maintain viable populations and it has been suggested that the interconnectivity of protected areas should be considered of the same importance as the sites themselves. Preserving, improving and restoring connectivity and movement corridors in fragmented landscapes are therefore essential elements in any conservation strategy. Recently, researchers have started to relate gene-flow patterns to landscape features in order to assess the extent to which landscape elements hinder or facilitate the movement of individuals. The main objective of this study is to use genetics-based resistance surfaces to perform rigorous landscape connectivity analyses in order to test how well regional sets of protected areas in Europe are integrated into functional ecological networks. While these landscape genetic approaches provide a key foundation for rigorous analysis of landscape resistance to movement, there are, however, a number of important basic questions related to optimal study design where additional research is needed to advance the field of landscape genetics and to make outputs for conservation planning more robust. Specifically, working on three mammal species, I want to (a) replicate species-specific landscape genetic analyses across multiple European study areas to test if the same landscape features are found to be influencing gene flow in different regions, (b) perform landscape genetic analyses on co-distributed species to test if the same landscape features are found to be influencing gene flow in different species in the same study area, (c) assess the influence of sample size on which landscape features are found the be influencing gene flow and (d) use the results from the landscape genetic analyses to derive empirically-validated movement corridors (for individual & multiple species) and to assess how well these are integrated into established protected area networks.
