Current threats to biodiversity, such as climate change, are thought to alter the within-species genetic diversity among microhabitats in highly heterogeneous alpine environments. Assessing the spatial organization and dynamics of genetic diversity within species can help to predict the responses of organisms to environmental change. In this study, we evaluated whether small-scale heterogeneity...

Recent advances in population genomics have triggered great interest in the genomic landscape of divergence in taxa with ‘porous’ species boundaries. One important obstable of previous studies of this topic was the low genomic coverage achieved. This issue can now be overcome by the use of ‘next generation’ or short-read DNA-sequencing approaches capable of assaying many thousands of...
