Plant phylogeography in Southern South America
This thesis is a phylogeographic investigation into plant species from Patagonia, and aims to infer their past distributions from the study of genealogical lineages. These species have gone through several events such as glacial periods, volcanism and topographical change which are expected to contr...

This thesis is a phylogeographic investigation into plant species from Patagonia, and aims to infer their past distributions from the study of genealogical lineages. These species have gone through several events such as glacial periods, volcanism and topographical change which are expected to contribute to the divergence of genetic lineages by shaping distributions, isolating populations and therefore changing their genetic structure. So understanding how these processes have affected populations is important to get information on how the biodiversity in the region has been assembled, to identify hotspots of intra-specific diversity and therefore to establish potential conservation priorities.
