A major work from the author of Naturalized Mammals and Naturalized Birds. Man has been transporting animals around the world for thousands of years. Many introductions are unsuccessful, but where species do succeed in establishing themselves, the consequences can be disastrous. They can transmit new parasites and diseases, damage crops and other resources, out-compete native species, or produce genetic changes in native populations. The author discusses the ecological and economic impacts that naturalized vertebrates have had on the native flora and fauna of the countries to which they have been introduced - either deliberately or accidentally.
