The framework calculates how projected temperature change would alter the creature's metabolism and life cycle. The researchers tested their model on a species of nematode, or roundworm, that lives in the Arctic and primarily infects caribou (above). As Arctic temperatures increase, the parasite's infectious season could split from what is now a continuous spring-to-fall transmission season into two longer fall and spring seasons separated by a hot, unlivable summer.
