As aquatic oxygen levels decrease with the changing climate, marine and lakewater species face a challenging task of adapting to hypoxic environments – or risk perishing. To examine potential for adaptation, researchers investigated two populations of threespine stickleback: one from a lake that naturally experiences seasonal long-term hypoxia and the other one that does not.
