Warm Freshwater Ecosystems

These systems are characterized as 4th order and larger nontidal riverine systems, which includes many of the intermediate and larger size rivers, such as the Penobscot, Connecticut, Hudson, Delaware, and Susquehanna Rivers and their larger tributaries of the northeastern U.S.  Fish passage, thermal stress, and ecological flows are likely important issues in these systems.  Fish health issues and invasive species are also of importance.  Researchers at the LSC are conducting a variety of studies on these issues to aid management and conservation of associated species.  Example key representative species include freshwater mussels, submerged aquatic vegetation, bass, sturgeon, eel, perch, shad, walleye.
