Dispersal Biology of Desert Plants by Karen van Rheede van Oudtshoorn,Margaretha W. van Rooyen Pdf

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.

Seed Germination in Desert Plants by Yitzchak Gutterman Pdf

During germination, the most resistant stage of the life cycle - the seed - changes to the most sensitive stage, namely the seedling. Therefore, in desert plant species seed dispersal and subsequent germination in the optimum time an place place are particularly critical parameters. Discussed here are the ways and means by which desert plants have adapted through the course of evolution to their extreme environment. Two such strategies which have evolved are a) plants with relatively large and protected seeds which germinate when the chance of seedling survival is high and the risk relatively low or b) those with an opportunistic strategy: minute seeds which germinate after low rainfall under high risk for seedling survival if additional rain does not follow. Most species adopt a combination of the two mechanisms. Species have adapted both genotypically and phenotypically, both aspects of which are also discussed in this thorough text. The reader is provided with a good understanding of the complex influences on each seed traced through from initial development to germination stage regarding germination preparation and subsequent survival.

Survival Strategies of Annual Desert Plants by Yitzchak Gutterman Pdf

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.

Desert Plants by Kishan Gopal Ramawat Pdf

Deserts appear very fascinating during our short visits. However, the lives of plants and animals are very dif?cult under the harsh climatic conditions of high tempe- ture and scant water supply in deserts, sometimes associated with high concent- tions of salt. The editor of this book was born and brought up in the Great Indian Desert, and has spent much of his life studying the growth and metabolism of desert plants. It is very charming on a cool summer evening to sit at the top of a sand dune listening only to blowing air and nothing else. It has been my dream to prepare a volume on desert plants encompassing various aspects of desert plant biology. In this book, I have tried to present functional and useful aspects of the vegetation resources of deserts along with scienti?c input aimed at understanding and impr- ing the utility of these plants. The scant vegetation of deserts supports animal life and provides many useful medicines, timber and fuel wood for humans. Therefore, there are chapters devoted to medicinal plants (Chap. 1), halophytes (Chaps. 13, 14), and fruit plants (Chaps. 17, 20). Desert plants have a unique reproductive biology (Chaps. 9–11), well-adapted eco-physiological and anatomical charact- istics (Chap. 7), and specialised metabolism and survival abilities. These plants are dif?cult to propagate and pose many problems to researchers developing biote- nological approaches for their amelioration (Chaps. 18–20).

Structure-Function Relations of Warm Desert Plants by Arthur C. Gibson Pdf

For centuries biologists have been extremely interested in the structure of desert plants as examples of natural selection to harsh environmental conditions. Indeed, desert plants are frequently used as examples in many biology classes and textbooks to illustrate natural selection, but this has led to an unfortunate litany of errors and misconceptions about desert plant adaptations. This new synthesis focuses on plants of lowland tropical and subtropical arid deserts. Readers will be surprised to discover that many features commonly ascribed to desert plants are rareley observed in the most common species. Instead, the typical structural adaptations of nonsucculent warm desert plants are now viewed as ways to maximize photosynthetic rate.

Principles of Dispersal in Higher Plants by L. van der Pijl Pdf

Reviewers from diverse branches of botany have exerted pressure to have chapters dealing with their field extended. If only to cover his incompetence, the author could not accede to these requests. Nor was it possible to respond to Eastern European urgings to extend the classificatory terminology, especially in ChapterX. He is grateful for indications of factual shortcomings in the chosen field, especially for those by Dr. RUDOLF SCHMID (Ann Arbor), who provided exten sive comment. L. VAN DER PIlL The Hague, spring 1972 Preface to the First Edition The work offered here is a companion volume to the work by K. FAEGRI and 1. VAN DER PIJL, Principles of Pollination Ecology, whim. deals with the preced ing phase of reproduction in plants. In the present work too, the emphasis is on principles and ecology. It is neither an enumeration of mechanisms, nor a compilation of cases. RIDLEY'S monumental work The Dispersal of Plants Throughout the World comprises 700 large pages of small print, and research has proceeded since then. Though this work is more than just a compilation and contains much insight and thoughts on principles in addition to reviews, its completeness hinders its use as a text book. As a reference work, it is unsurpassed and the writer made frequent use of it. The writer paid special attention to functional backgrounds for the use of taxonomists working with "characters" and to biosystematics at the macro-level.

The Biology of Deserts by David Ward Pdf

This book offers a concise but comprehensive introduction to desert ecology and adopts a strong evolutionary focus. As with other titles in the Biology of Habitats Series, the emphasis in the book is on the organisms that dominate this harsh environment, although theoretical and experimental aspects are also discussed. In this updated second edition, there is a greater focus on the effects of climate change and some of its likely effects on deserts, seeing desertification as among the most serious results of climate change, leading ultimately to the increasing size of arid and semi-arid regions. The Biology of Deserts Second Edition includes a wide range of ecological and evolutionary issues including morphological and physiological adaptations of desert plants and animals, species interactions, the importance of predation and parasitism, food webs, biodiversity, and conservation. It features a balance of plant and animal (both invertebrate and vertebrate) examples, and also emphasizes topical applied issues such as desertification and invasive species. The book concludes by considering the positive aspects of desert conservation. This accessible textbook is intended for senior undergraduate and graduate students, as well as professional ecologists, conservation practitioners, and resource managers working in the field of desert ecology.
