Maternal effect key to fish combating climate change

Jul 14, 2014 by Paul Mayne

( —According to research by Western scientists, thermal tolerance in a wild fish population is a key factor in understanding how animal species adapt to climate change.

Western Sciences professors Nico Munoz and Bryan Neff, along with collaborators at the University of British Columbia and Yellow Island Aquaculture Limited, conducted the first-ever genetic assessment of oxygen-limited, thermal (heat) tolerance and cardiac (heart) performance within a coastal population of chinook salmon.

The investigators found compelling results, which help explain the adaptive mechanisms available to fish populations faced with rising temperatures in the world's oceans. The findings were published this week inProceedings of the Royal Society B.
