Abstract (from http://www.pnas.org/content/early/2013/04/10/1222724110.abstract): Most examples of seasonal mismatches in phenology span multiple trophic levels, with timing of animal reproduction, hibernation, or migration becoming detached from peak food supply. The consequences of such mismatches are difficult to link to specific future climate change scenarios because the responses across trophic levels have complex underlying climate drivers often confounded by other stressors. In contrast, seasonal coat color polyphenism creating camouflage against snow is a direct and potentially severe type of seasonal mismatch if crypsis becomes compromised by the animal being white when snow is absent. It is unknown whether...

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...
