My research involves the use of evolutionary and ecological genetics (and increasingly genomics) to understand patterns of species distribution. I also utilise niche modelling to help understand how these distributions might have looked in the past, and what they might look like under various climate change scenarios.
I am currently studying the rare Scottish montane species, Dwarf birch (Betula nana), which has a severely restricted and declining distribution in the Scottish Highlands. Among threats from changing land management, climate change and overgrazing, it is also undergoing severe introgression from increasingly abundant related species. I am exploring the possible consequences of this, and how this might be identified in other species around the world.
Mapping genetic diversity, ecological niche modelling, habitat fragmentation, population genetics, parentage analysis, gene flow, introgression and hybridisation.
