different niches within the same habitat In the App Mtns, several species of salamander live in or near a stream, The largest species lives in the stream and along its edges, a smaller species lives on land within a meter or two of the stream, and a smaller species lives about 3-5 meters away from the stream. In this region, these three salamander species are using:
