Yosemite National Park, CA — Scientists studying Yosemite National Park´s wildlife say the effects of global warming may be forcing several animal species to move to higher altitudes.
A team of scientists from U-C Berkeley were retracing a recorded account of the park´s mammals, birds and reptiles catalogued about 90 years ago when they made the discovery.
They say some of the shifts may also be natural migrations or due to California wildfires.
