Fish of Antarctica threatened by climate change
Date:2/14/2012

but we found evidence that this adaptive radiation is not linked to a single trait, but to a combination of factors," Near said.

This evolutionary success story is threatened by climate change that has made the Southern Ocean around Antarctica one of the fastest-warming regions on Earth. The same traits that enabled the fish to survive and thrive on a cooling earth make them particularly susceptible to a warming one, notes Near.

"Given their strong polar adaptations and their inability to acclimate to warmer water temperatures, climate change could devastate this most interesting lineage of fish with a unique evolutionary history," Near said.
