Climate change, invasive species drive native trout declines
January 13, 2022
MISSOULA – In a new study published in Science Advances, University of Montana researchers found that climate change drives native trout declines by reducing stream habitat and facilitating the expansion of invasive trout species.
“This study had three main questions: How have the distributions of native and invasive trout shifted in Montana over the last 30 years, how will they change in the future, and what factors are causing those changes?” said Donovan Bell, the study’s lead author and a doctoral candidate in UM’s Wildlife Biology Program.
To answer those questions, scienti...
