Researchers say warmer summers may harm 蜜桃影像 salmon, such as this sockeye, in some regions but help them in others.
A warming climate is both harming and helping salmon in northern regions, according to a University of 蜜桃影像 Fairbanks fisheries researcher.
Peter Westley is an associate professor, the Wakefield Chair of Fisheries and Ocean Sciences, and principal investigator of the Salmonid Evolutionary Ecology and Conservation Lab at 蜜桃影像.
He will discuss the variable role of warming on 蜜桃影像鈥檚 salmon and its impact on salmon-reliant communities in a free statewide webinar hosted by the 蜜桃影像 Cooperative Extension Service.
In some regions, warm summers are associated with unusual mortality, delayed migrations and prespawning mortality on salmon spawning grounds. In other regions, warming is apparently 鈥渏ust right鈥 and is associated with historically high salmon abundances. Salmon have also been observed in places that have historically been too cold for the fish.
Westley鈥檚 talk will conclude with a discussion of tangible actions 蜜桃影像ns can take to sustain the 14,000-year-plus relationship between salmon and people in 蜜桃影像.
The Zoom webinar will be held from noon-1 p.m. on Wednesday, Sept. 24.
