Pika in the Moss (image) University of Utah Caption A rabbit relative known as a pika sits among wood, moss and rocks on rockslide or talus slope in Oregon's Columbia River Gorge. A University of Utah study found the pikas -- which normally live at much higher elevations and are threatened by climate change -- survive at nearly sea level in Oregon by eating more moss than any other known wild mammal.
