Naturalists have managed to finally rediscover a species of extremely rare and endangered mountain yellow-legged frogs, which were last spotted some half a century ago in California. Scientists from the United States Geological Survey (USGS) and the San Diego Natural History Museum discovered the elusive amphibians in the San Bernardino National Forest, after following the same course as a San Jacinto Wilderness expedition, conducted in 1908. LiveScience reports that biologists are optimistic that the find will aid them in their efforts to conserve this rare species. At the global level, the challenges facing frogs, and amphibians in general, are very diverse and difficult to overcome. Countless species lose their habitat quickly, either on account of human intervention, or because global warming modifies the established ecosystems. Despite the fact that these animals can adapt very quickly, even their fast evolutionary pace cannot keep up with the changes that happen in !
their environments from year to year. Additionally, they are also threatened by the dangerous chytrid fungus, a pathogen that decimates entire frog populations. On the bright side of things, with the new discovery, the Californian mountain yellow-legged frogs could have a shot at survival. Captive breeding programs, coupled w...
