“They have evolved to live in very cold, stable conditions and they already live in the coldest, most stable ecosystem on Earth,” said Anne Todgham, an associate professor in the UC Davis Department of Animal Science who specializes in how aquatic life copes with changing environments. Todgham studies stress in sea creatures in a wide variety of locations, including the ice-covered continent at the southern tip of the globe.
Oceans absorb about one-third of the CO2 humans release into the atmosphere. That may be good for the air, but it is hard on the health of the sea. Climate change and marine pollution is stressing virtually all aquatic life, but Todgham says polar species may have it the worst.
