Climate change is making conditions harder for Wisconsin trout. But there is hope.

Noted: In a study published in the journal Ecosphere in December, Alex Latzka, a fisheries biologist with the Wisconsin Department of Natural Resources, and Bryan Maitland, a postdoctoral fellow at the University of Wisconsin-Madison’s Aquatic Sciences Center, compared annual brook and brown trout population numbers over nearly three decades with climate and weather data from the streams the trout swam in.
