Climate change prompts Alaska fish to change breeding behavior

One of Alaska’s most abundant freshwater fish species is altering its breeding patterns in response to climate change. This could impact the ecology of northern lakes, which already acutely feel the effects of a changing climate.
That’s the main finding of a recent University of Washington study published in Global Change Biology that analyzed reproductive patterns of three-spine stickleback fish over half a century in Alaska’s Bristol Bay region. The data show that stickleback breed earlier and more often each season in response to earlier spring ice breakup and longer ice-free summers.
