It seems plants and animals should react differently to changes in their climate niches, the temperature and precipitation conditions under which they live.
After all, animals can move to find food, water or shade, while plants mostly must sit and take what comes.
But a new study of more than 2,000 plant and animal species in the journal Nature Ecology & Evolution suggests flora and fauna actually share similar responses.
Co-author John J. Wiens, a professor in the Department of Ecology and Evolutionary Biology at the University of Arizona, said the results mirror current patterns caused by climate change.
“We’ve seen a pattern of local extinctions from the climate change that’s happened already, and the frequencies of local extinctions are actually similar for both plants and animals,” he said.
Wiens and his colleagues tested 10 predictions relating plants and animals to their climate niches.
Members of the 19 plant groups and 17 vertebrate groups followed similar patterns in all 10 cases.
A few examples: Plants and animals tolerate a similar range of conditions; they both adapt at similar rates to changes in their environments; and both can adjust much more quickly to cooler and wetter conditions than to heating or drying trends.
The findings suggest general rules of climatic-niche evolution might hold true for both flora and fauna.
