This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.

The updated edition of the classic, fundamental book on weedscience Weed Science provides a detailed examination ofthe principles of integrated weed management with important detailson how chemical herbicides work and should be used. This revisedFourth Edition addresses recent developments affecting weedscience. These include the increased use of conservation-tillagesystems, environmental concerns about the runoff of agrochemicals,soil conservation, crop biotechnology, resistance of weeds andcrops to herbicides, weed control in nonagricultural settings andconcerns regarding invasive plants, wetland restoration, and theneed for a vastly improved understanding of weed ecology. Current management practices are covered along with guidance forselecting herbicides and using them effectively. To serve as a moreefficient reference, herbicides are cross-listed by chemical andbrand name and grouped by mechanism of action and physiologicaleffect rather than chemical structure. In addition, an introductionto organic chemistry has been added to familiarize readers withorganic herbicides. Also included are guidelines on weed-controlpractices for specific crops or situations, such as small grains,row crops, horticultural crops, lawns and turf, range land, brush,and aquatic plant life. Generously supplemented with 300 drawings, photographs, andtables, Weed Science is an essential book for students taking anintroductory course in weed science, as well as a reference foragricultural advisors, county agents, extension specialists, andprofessionals throughout the agrochemical industry.
