Invasive Species consists of 18 chapters contributed by different authors, all directed at an overview of “vectors” that transport species to new regions in which the organisms are not indigenous. The intent is to provide an overview of the transnational transfers of such species—crop pests, pets, ornamental plants, potential invaders of ecosystems, pathogens, others—with a view to improving the efficacy of policy and management strategies for reducing said transfers. The book is only partially successful at this.
