Stanford researchers: Global warming is killing frogs and salamanders in Yellowstone Park

Frogs and salamanders, those amphibious bellwethers of environmental danger, are being killed in Yellowstone National Park. The predator, Stanford researchers say, is global warming. Biology graduate student Sarah McMenamin spent three summers in a remote area of the park searching for frogs an...

Snakes, salamanders and other creatures thrive in areas with higher deer populations

COLUMBUS, Ohio Reducing the number of deer in forests and parks may unexpectedly reduce the number of reptiles, amphibians and insects in that area, new research suggests. A recent study by researchers at Ohio State University and National Park Service found that higher deer activity is modif...

Thriving hybrid salamanders contradict common wisdom

A new UC Davis study not only has important findings for the future of California tiger salamanders, but also contradicts prevailing scientific thought about what happens when animal species interbreed. The study, by former UC Davis doctoral student Benjamin Fitzpatrick (now on the faculty of U...
