New model includes migration rates, competition between species

SUMMIT COUNTY — Global warming could drive species extinctions at a faster rate than predicted by most climate models because the existing research doesn’t account for species competition and movement, according to University of Connecticut ecologist Mark Urban.

“We have really sophisticated meteorological models for predicting climate change,” Urban said. “But in real life, animals move around, they compete, they parasitize each other and they eat each other. The majority of our predictions don’t include these important interactions.” Continue reading
