Influence of Beaver Activity on Summer Growth and Condition of Age‐2 Atlantic Salmon Parr
Abstract The activity of beavers Castor canadensis in freshwater environments can have considerable localized impacts on the physical and biological components of riparian ecosystems. By changing the habitat of a stream, beaver dams can cause spatial variation in growth opportunity that may have dir...
