Climate warming contributes to native and invasive trout hybridization

Results from a study conducted by Dr. Clint Muhlfeld, US Geological Survey, with funding support from the Great Northern LCC, was recently published in the journal Nature Climate Change.

The paper reports that rapid climate warming contributes to hybridization between native and invasive trout species. Muhlfeld and his collaborators examined long-term genetic monitoring data with high-resolution climate and stream temperature predictions. Their findings indicate that invasive hybridization could result in genomic extinction for many native species.
