Ecosystems often rely on processes that import nutrients produced elsewhere. Animals can facilitate the movement of nutrients if they move between different ecosystems or live at the margins of distinct habitat. In the Appalachians, forested streams rely on connections between upland forests and streams. There, salamanders likely have an important role in connecting upland and stream ecosystems. This presentation will delve into current research on how animals connect ecosystems, with a particular focus on what role salamanders have in the Appalachians. The presentation will include results from recent work done in Macon County, supported by HBS.
