Mares and you can download with pub, pdf, txt, doc, and more file format with free account. encyclopedia of deserts represents a milestone: it is the first comprehensive reference to the first comprehensive reference to deserts and semideserts of the world. approximately seven hundred entries treat subjects ranging from desert survival to the way deserts are formed. topics include biology (birds, mammals, reptiles, amphibians, fishes, invertebrates, plants, bacteria, physiology, evolution), geography, climatology, geology, hydrology, anthropology, and history. the thirty-seven contributors, including volume editor michael a. mares, have had extensive careers in deserts research, encompassing all of the world’s arid and semiarid regions. the encyclopedia opens with a subject list by topic, an organizational guide that helps the reader grasp interrelationships and complexities in desert systems. each entry concludes with cross-references to other entries in the volume, inviting the reader to embark on a personal expedition into fascinating, previously unknown terrain. in addition a list of important readings facilitates in-depth study of each topic. an exhaustive index permits quick access to places, topics, and taxonomic listings of all plants and animals discussed. more than one hundred photographs, drawings, and maps enhance our appreciation of the remarkable life, landforms, history, and challenges of the world’s arid land.

Description : Read Now Survival Strategies Of Annual Desert Plants by Yitzchak Gutterman and you can download with pub, pdf, txt, doc, and more file format with free account. annual desert plant species of unrelated taxa in the negev desert of israel have developed complementary sets of adaptations and survival strategies as ecological equivalents with physiological, morphological and anatomical resemblances, in the various stages of their life cycles. after 40 years of research in hot deserts yitzchak gutterman provides a comprehensive treatise of such adaptations and strategies. in doing so he covers the following topics: post-maturation primary seed dormancy, which prevents germination of maturing seeds before the summer; seed dispersal mechanisms with escape or protection strategies; cautious or opportunistic germination strategies; seedling drought tolerance. the day-length is an important factor in regulating flowering as well as the phenotypic plasticity of seed germination which is also affected by maternal factors.

Description : Read Now Dispersal Biology Of Desert Plants by Karen van Rheede van Oudtshoorn and you can download with pub, pdf, txt, doc, and more file format with free account. dispersal processes have important effects on plant distribution and abundance. although adaptations to long range dispersal (telechory) are by no means rare in desert plants, many desert plant species do not possess any features to promote dispersal (atelechory), while others have structures that hamper dispersal (antitelechory). the high frequency with which atelechorous and antitelechorous mechanisms are present in plants inhabiting arid areas indicates the importance of these adaptations. among the benefits derived from these adaptations are the spreading of germination over time, the provision of suitable conditions for germination and subsequent seedling establishment, and the maintenance of a reservoir of available seeds (seed bank). this book describes the ways and means - anatomical, morphological and ecological - by which dispersal in desert plants has evolved to ensure the survival of these species in their harsh and unpredictable environment.

Wickens and you can download with pub, pdf, txt, doc, and more file format with free account. economic plants have been defined by sepasat as those plants that are utilised either directly or indirectly for the benefit of man. indirect usage includes the needs of man's livestock and the maintenance of the environment; the benefits may be domestic, commercial or aesthetic. economic plants constitute a large and so far uncalculated percentage of the quarter of a million higher plants in the world today. however, it has been calculated that 10% (25 000) of these species are now on the verge of extinction and extinction means that a genetic resource that could be of benefit to man will be lost for ever. furthermore, for every species lost an estimated 10-30 other dependent organisms are also doomed. fewer than 1 per cent of the world's plants have been sufficiently well studied for a true evaluation of the potential floral wealth awaiting discovery, not only in the rain forests, which man is now actively destroying at a rate of 20 ha a minute, but also in the very much neglected dry areas of the world.

Description : Read Now The Future Of Drylands by Cathy Lee and you can download with pub, pdf, txt, doc, and more file format with free account. dryland ecosystems support a surprising amount of biodiversity; desertification, however, is a significant land degradation problem in the arid, semi-arid and dry sub-humid regions of the world. the situation is likely to worsen with high population growth rates and accompanying land-use conflicts. the contributions to this publication, an international scientific conference held under the leadership of unesco, address these issues and offer practical solutions for combating desertification along with conserving and sustainably managing dryland ecosystems. this volume documents how improved understanding of drylands provides insight into the health and future prospects of these ecosystems that should help ensure that dryland communities enjoy a sustainable future.--publisher's description.
