Data from: Pumping ions: rapid parallel evolution of ionic regulation following habitat invasions

Carol Eunmi Lee, Michael Kiergaard, Gregory William Gelembiuk, Brian Donovan Eads & Marijan Posavi
Marine to freshwater colonizations constitute among the most dramatic evolutionary transitions in the history of life. This study examined evolution of ionic regulation following saline-to-freshwater transitions in an invasive species. In recent years, the copepod Eurytemora affinis has invaded freshwater habitats multiple times independently. We found parallel evolutionary shifts in ion-motive enzyme activity (V-type H+ ATPase, Na+/K+-ATPase) across independent invasions and in replicate laboratory selection experiments. Freshwater populations exhibited increased V-type H+ ATPase activity in...
