As the threat of climate change has become more serious in recent decades, biologists have sounded the alarm about the threat to brook trout populations across the species’ range. Salvelinus fontionalis has always been seen as the trout species most susceptible to rising water temperatures, but a new study has found that brook trout “may have a genetic trick up their scales when it comes to adapting, with limitations, to heatwaves that threaten their existence.” A study led by researchers at Penn State suggests a protective genetic response to thermal stress can be passed on from one generation brookies to the next. This is a rare bit of climate-related good news for anglers from Georgia to eastern Canada.
