Nonindigenous freshwater organisms

Renata Claudi, J. Leach

"Alien species invade aquatic ecosystems by both intentional and accidental means. Non-indigenous Freshwater Organisms focuses on this infringement into North American aquatic ecosystems. The 30 chapters measure the devastating ecological, and sometimes economic, impacts caused by the encroachment of species such as the zebra mussel and the American bullfrog."--BOOK JACKET.
