Biological Invasions

The problem of biological invasions in plants, animals and micro-organisms is examined in this book. Rather than concentrate on local patterns a complete global picture is reviewed, including divergent points of view from world renowned experts. The phenomena of biological invasions and the damage which often accompanies an invasion are discussed, with particular reference to the serious problem of the extinction of species and the replacement of entire ecosystems. The programme addressed three specific issues relating to the nature of invading plants and animals: the factors that determine whether a species will be an invader or not; the site properties that determine whether an ecological system will be prone to, or resistant to, an invasion; and the development of management systems using the knowledge gained. The primary focus of the programme was on those animals, plants and micro-organisms that have been successful invaders of non-agricultural regions, with an emphasis on those that have disrupted ecosystem function. This book is the result of a culminating workshop held at the East-West Center of Honolulu, Hawaii.
