The potential influence of changing climate on the persistence of inland native trout

Date: November 13, 2012
Presenter(s): Jeffrey L. Kershner, Steven W. Hostetler
Description: Bioclimatic models predict large reductions in native trout across the Rocky Mountains this century but lack specific details regarding how this change will occur. This project addresses the need for more complete evidence and more accurate vulnerability assessments to show how salmonid populations are adjusting to climate change. This webinar will also explore some of the biological implications, and their relative importance, related to a warming climate including upstream shifts in salmonid habitats, increased wildfire disturbances, and declining summer habitats. For example, temperature increases may be more relevant where habitat fragmentation is less extensive and population boundaries are thermally mediated. Moreover, summer flow declines and disturbances associated with wildfire are likely to be more important where trout populations are heavily fragmented and constrained to small headwater refugia.
