From the reviews: "This second volume ... focuses on non-indigenous freshwater species. The book includes 39 chapters ... by 82 contributors from 18 countries. ... I do like the book and can recommend it. It is well written throughout ... . References are provided separately for each chapter ... which is very useful when photocopying a chapter. The book's index is very useful, too ... . In sum, the book ... will have a very interesting read." (Jonathan M. Jeschke, Basic and Applied Ecology, Vol. (10), 2009)
