Data from: Comparative population genomics reveals key barriers to dispersal in Southern Ocean penguins
The mechanisms that determine patterns of species dispersal are important factors in the production and maintenance of biodiversity. Understanding these mechanisms helps to forecast the responses of species to environmental change. Here we used a comparative framework and genome-wide data obtained t...

The mechanisms that determine patterns of species dispersal are important factors in the production and maintenance of biodiversity.
