Ecosystem engineers: North American beavers change functioning of subantarctic stream ecosystems

A recent issue of Columns, the University of Georgia research magazine, highlighted the research being conducted by Dr. Christopher Anderson (OSARA President) and Dr. Amy Rosemond (OSARA Advisor) in the Cape Horn Biosphere Reserve. Their work has shown that the introduction of the North American beaver (Castor cannadensis) has caused increases in stream ecosystem function, while at the same time decreasing aquatic diversity. These research findings are being used as well for a regional invasive species management plan.
