Abstract (from http://onlinelibrary.wiley.com/doi/10.1111/gcb.13681/full): Hybridization between invasive and native species, a significant threat to worldwide biodiversity, is predicted to increase due to climate-induced expansions of invasive species. Long-term research and monitoring are crucial for understanding the ecological and evolutionary processes that modulate the effects of invasive species. Using a large, multidecade genetics dataset (N = 582 sites, 12,878 individuals) with high-resolution climate predictions and extensive stocking records, we evaluate the spatiotemporal dynamics of hybridization between native cutthroat trout and invasive rainbow trout, the world's most widely introduced invasive fish,...
Climate change and invasive species are major threats to native biodiversity, but few studies have examined their combined effects at large spatial and temporal scales. Using 21,917 surveys collected over 30 years, we quantified the impacts of climate change on the past and future distributions of five interacting native and invasive trout species throughout the northern Rocky Mountains, USA. We found that the occupancy of native bull trout and cutthroat trout declined by 18% and 6%, respectively, from 1993 to 2018 and was predicted to decrease by an additional 39% and 16% by 2080. However, reasons for the occupancy reductions differed markedly across species; increasing water temperature and decreasing streamflow...
