Study looks at hybridization of trout in Northern Rocky Mountains

Global warming is intensifying the hybridization of native and non-native trout in the northern Rocky Mountains, according to a new study from the U.S. Geological Survey and other scientists. The trend is a serious threat to the biodiversity of Rocky Mountain aquatic ecosystems, says the study published in the journal Global Change Biology.
As non-native rainbow trout, introduced by early settlers, interbreed with cutthroat trout it leads to a decline in local adaptations that can threaten the long-term survival of species. Preserving the genetic integrity of native species is important for resiliency, the scientists said.
