Invasions of alien organisms beyond their original range is a major threat to human health as well as to biodiversity. The preface, reprinted from Biological Invasions 1:97-8, 1999, details the interdisciplinary Global Invasive Species Program built on an earlier scientific synthesis of the problem. A dozen chapters by international contributors present economic analyses of such ecological onslaughts as a step toward developing decision rules for their management; case studies in affected areas (from rabbit calicivirus disease in Australia to invasive species in African lakes), and control programs; and conclusions as to their causes and consequences. Figures and tables summarize bioeconomic data and models. The editors are affiliated with the U. of York, UK. Annotation c. Book News, Inc., Portland, OR (booknews.com) Read Less
