The butterfly effect: climate change could cause decline of some alpine butterfly species


The long-term effects of climate change suggests that the butterfly effect is at work on butterflies in the alpine regions of North America, according to a new study by University of Alberta scientists—and the predictions don’t bode well.

“We often frame the effects of climate change directly onto a species as the future becoming either too hot, too dry, or too wet,” explained Alessandro Filazzola, postdoctoral fellow in the Faculty of Science Department of Biological Sciences and lead author on the study. “However, climate change can have indirect effects such as through the food resources of a species. These effects are more likely to affect butterflies, because as caterpillars they often feed on one or a few plant species.” MORE
