Brook trout, an iconic coldwater fish species native to streams and lakes in the eastern United States and Canada, begin to experience declines in growth rate in water above 61 degrees Fahrenheit and acute heat stress above 68 degrees Fahrenheit. In this study, researchers caught, sampled and released fish in four streams in Pennsylvania. Credit: Jason Keagy/Penn State. All Rights Reserved.

Native bee populations can bounce back after honey bees move out

Managed honey bees have the potential to affect native bee populations when they are introduced to a new area, but a study led by researchers at Penn State suggests that, under certain conditions, the native bees can bounce back if the apiaries are moved away.
