Coping with climate stress in Antarctica
Some polar fish can cope with warming or ocean acidification, but not both together
Some Antarctic fish living in the planet’s coldest waters are able to cope with the stress of rising carbon dioxide levels the ocean. They can even tolerate slightly warmer waters. But they can’t deal with both stressors at the same time, according to a study from the University of California, Davis.
The study, published recently in the journal Global Change Biology, of emerald rockcod is the first to show that Antarctic fishes may make tradeoffs in their physiology and behavior to cope with ocean acidification and warming waters.
(The research is described in a web feature, “The Last Stop,” at the UC Davis Science & Climate website.)
“In dealing with climate stress, these fish are really bad multi-taskers,” said senior author Anne Todgham, an associate professor with the UC…
