Climate change alters the geographical range of species. Such shifts can affect species in major ways, such as changing their abundance or bringing adjacent, closely related species into contact. Potts at al. found that rapidly warming waters in the Angola-Benguela Frontal Zone over the last three decades caused the African kob fish Argyrosomus coronus to move southward, where they now live—and spawn—in some of the same places as a related species. Species often overlap at range boundaries, but climate-driven overlap makes it harder for people to manage economically important species and changes the way species fit into their ecosystems.
