Bridging the Scotia Arc: Climate-driven shifts in connectivity of the freshwater crustacean <em>Branchinecta gaini</em> in sub-Antarctic and Antarctic ecosystems

The datasets presented here correspond to the three methodologies combined. First, it corresponds to obtaining mitochondrial DNA sequences (cox1 and 16S). Second, the SNPs obtained on the basis of the filtering described in the methodology and finally the occurrences used for the niche models. All these data correspond to the species Branchinecta gaini, an Anostraco throughout its distribution in the southern part of South America, South Georgia and maritime Antarctica.
