A species of frog endemic to the Pacific Northwest faces a 50 per cent increase in the probability of extinction by the 2080s due to climate change, according to a new study. A species of frog endemic ...

A major challenge facing wildlife biologists is understanding why some species go extinct while others persist in the same habitat. To address this question, we investigated whether tree canopy ...

New research shows that juvenile northern red-legged frogs that have experienced climate-related stress as tadpoles are less likely to move on land, putting their survival at risk. New Oregon State ...
