Invasive species are one of the major threats to natural ecosystems and the services they provide. This book focuses on invasives (particularly insect species) currently implicated in impacting ecosystems and native communities in the tropics. Biological invasions require a multidisciplinary approach across taxa and habitats. This book updates recent advances in biological invasion research and highlights the impacts of invasives, identifies and explains mechanisms of invasion, and identifies research gaps. The book shows examples of species at risk from invasions, describes invasive species information networks, and shows analysis of current distributions and modeling of invasive populations. Chapters also cover prevention and legislation, global information sharing, and invasive species management practices. The book consists of four sections dealing with every aspect of invasiveness.This book will be useful for scientists, researchers, ecologists, economists, planners and others working on biological invasions, biodiversity, landscape and land use planners. It will be useful to national and International organizations for monitoring, networking and coordinating efforts in the management of biological invasives.
