Today, native plants and water conservation are subjects of vital interest to cities, offices, homeowners, and agriculture alike, as all are affected by the growing shortage of water in the Intermountain region.This comprehensive volume provides specific information about shrubs, trees, grasses, forbs, and cacti that are native to most states in the Intermountain West, and that can be used in landscaping to conserve water, reflect and preserve the region's landscape character, and help protect its ecological integrity. The book is an invaluable guide for the professional

The global spread of plant species by humans is both a fascinating large scale experiment and, in many cases, a major perturbation to native plant communities. Many of the most destructive weeds today have been intentionally introduced to new environments where they have had unexpected and detrimental impacts. This 2003 book considers the problem of invasive introduced plants from historical, ecological and sociological perspectives. We consider such questions as 'What makes a community invasible?', 'What makes a plant an invader?' and 'Can we restore plant communities after invasion?' Written with advanced students and land managers in mind, this book contains practical explanations, case studies and an introduction to basic techniques for evaluating the impacts of invasive plants. An underlying theme is that experimental and quantitative evaluation of potential problems is necessary, and solutions must consider the evolutionary and ecological constraints acting on species interactions in newly invaded communities.

Biology of Apples and Pears is a comprehensive reference book on all aspects of pomology at the organ, tree and orchard level. It provides detailed information on propagation, root and shoot growth, root stock effects, canopy development in relation to orchard design, flowering, pollination, fruit set, fruit growth, fruit quality factors and quality retention in store. It also deals with mineral nutrition, water-relations and irrigation, diseases and pests and biotechnology. The book emphasises the scientific basis of modern tree and orchard management and fruit storage. It describes key cultivar differences and their physiology and genetics and environmental effects and cultivar x environment interactions in tropical and sub-tropical as well as temperate zone conditions. It is written for fruit growers, extension workers, plant breeders, biotechnologists and storage and crop protection specialists as well as for researchers and students of pomology and horticulture.

The present book gives a modernized and comprehensive overview of the degradation of major litter components as well as the sum of processes when forest plant litter decomposes, releases nutrients and turns into humus. Covering mainly boreal and temperate forests, the book gives a synthesis of the different sub-processes on the basis that decomposition is microbially mediated and develops a system in the decomposition processes leading to chemical changes in litter. Further, it introduces a conceptual model for litter transformations from litter fall until the decomposing litter accumulates as humus. The effects of substrate quality, climate, and their interactions on decomposition are presented as well as examples of litter types that break the basic pattern. A system is suggested for humus accumulation rates among forest systems, a system that may be a starting point for estimates of carbon sequestration in forest systems.
