GR: Until recently, naturalists said that invasive species introduced intentionally and accidentally by humans were the second most deadly force destroying nature. Construction of roads and towns was first. Most scientists are now saying that global warming will soon be number two. This article explains part of the reason.
“Brookies are freshwater fish native to eastern North America and threatened by climate change because of their requirement for cold stream temperatures. Brown trout are native to Europe and have been introduced all around North America.
“We know streams are warming due to climate change and non-native species are becoming increasingly abundant in many places,” said Nathaniel Hitt, U. S. Geological Survey research fish biologist. “Our research indicates that reducing Brown Trout numbers can benefit native Brook Trout where the species co-occur,” Hitt said. Brown trout management could help brookies be more resilient to anticipated effects of climate change, he added.
