So, some scientists from the U.S. Geological Survey were scouting for locations where they might attempt re-establishung the mountain yellow-legged frog, Rana muscova., following the first successful breeding of the nearly extinct species at the San Diego Zoo.
Not far away, a team from the San Diego Natural History Museum were following the trail of a 1908 expedition, so as to compare the earlier notes with the situation a century later to see how the ecology had changed.
Guess what? The two teams independently discovered completely unexpected wild populations of the endangered frogs. Yay!!
