Not all sockeye created equally when it comes to surviving climate change
A new study published this week in the journal Science indicates not all sockeye salmon stocks are well equipped to survive the increase in water temperature in the Fraser River that is projected to take place over the next 50 years. The study found that stocks that travel the farthest have evolved to have larger hearts and process oxygen more efficiently which may give these stocks a better chance of adapting to climate change. The study was done by researchers from the University of British Columbia, Fisheries and Oceans Canada and Simon Fraser University.
