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.

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.

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.

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).

Seedling Ecology and Evolution by Mary Allessio Leck,V. Thomas Parker,Robert Simpson Pdf

Seedlings are highly sensitive to their environment. After seeds, they typically suffer the highest mortality of any life history stage. This book provides a comprehensive exploration of the seedling stage of the plant life cycle. It considers the importance of seedlings in plant communities; environmental factors with special impact on seedlings; the morphological and physiological diversity of seedlings including mycorrhizae; the relationship of the seedling with other life stages; seedling evolution; and seedlings in human altered ecosystems, including deserts, tropical rainforests, and habitat restoration projects. The diversity of seedlings is portrayed by including specialised groups like orchids, bromeliads, and parasitic and carnivorous plants. Discussions of physiology, morphology, evolution and ecology are brought together to focus on how and why seedlings are successful. This important text sets the stage for future research and is valuable to graduate students and researchers in plant ecology, botany, agriculture and conservation.

Microbiology of Hot Deserts by Jean-Baptiste Ramond,Don A. Cowan Pdf

This book covers the wider aspects of the microbiology of hot desert soil ecosystems, compiling disparate information from a range of relevant desert soil microbial fields. The reader learns about microbial ecology of the more dominant and possibly most important desert habitats, detailing the phylogenetic and functional diversity of these different habitats as well as their potential role in desert ecosystem ecology. Particular attention is also given to microbial stress adaptation in hot desert soils. Furthermore, it is the first volume in this particular field to cover modern metagenomics technologies that can be applied to studies of all aspects of desert microbial communities. Additionally, the book explores viruses and viral communities, which are among the least studied (and little understood) components of desert soil microbial communities. Particular attention is also given to the roles of desert microbial communities in biogeochemical cycling of carbon, nitrogen and phosphorus. Through this book the reader discovers how desert microbiology has been at the forefront of Astrobiology and how it may be used conceptually in future terraforming strategies. Desert ecosystems are increasingly coming into focus given the impacts of climate change and desertification trends, making this volume particularly timely. Each of the chapters is authored by leading international researchers and is a must-read for microbial ecologists.

Seeds by Carol C. Baskin,Jerry M. Baskin Pdf

The new edition of Seeds contains new information on many topics discussed in the first edition, such as fruit/seed heteromorphism, breaking of physical dormancy and effects of inbreeding depression on germination. New topics have been added to each chapter, including dichotomous keys to types of seeds and kinds of dormancy; a hierarchical dormancy classification system; role of seed banks in restoration of plant communities; and seed germination in relation to parental effects, pollen competition, local adaption, climate change and karrikinolide in smoke from burning plants. The database for the world biogeography of seed dormancy has been expanded from 3,580 to about 13,600 species. New insights are presented on seed dormancy and germination ecology of species with specialized life cycles or habitat requirements such as orchids, parasitic, aquatics and halophytes. Information from various fields of science has been combined with seed dormancy data to increase our understanding of the evolutionary/phylogenetic origins and relationships of the various kinds of seed dormancy (and nondormancy) and the conditions under which each may have evolved. This comprehensive synthesis of information on the ecology, biogeography and evolution of seeds provides a thorough overview of whole-seed biology that will facilitate and help focus research efforts. Most wide-ranging and thorough account of whole-seed dormancy available Contains information on dormancy and germination of more than 14,000 species from all the continents – even the two angiosperm species native to the Antarctica continent Includes a taxonomic index so researchers can quickly find information on their study organism(s) and Provides a dichotomous key for the kinds of seed dormancy Topics range from fossil evidence of seed dormancy to molecular biology of seed dormancy Much attention is given to the evolution of kinds of seed dormancy Includes chapters on the basics of how to do seed dormancy studies; on special groups of plants, for example orchids, parasites, aquatics, halophytes; and one chapter devoted to soil seed banks Contains a revised, up-dated classification scheme of seed dormancy, including a formula for each kind of dormancy Detailed attention is given to physiological dormancy, the most common kind of dormancy on earth

Regeneration of Plants in Arid Ecosystems Resulting from Patch Disturbance by Yitzchak Gutterman Pdf

The main subject of this book is the interaction between diggings created by porcupines when consuming geophytes, and their influences on annual and perennial vegetation in a desert biome. The accumulation of run-off water in diggings and depressions made by animals increases the carrying capacity of these microhabitats in the desert biome. The accumulation of run-off water does not only benefit the natural vegetation; a system of human-made depressions can be evolved to increase the catchment of the run-off water that is typical to many desert habitats, and can lead to run-off agriculture in such areas. This book will be of interest to anyone working in the fields of development of deserts from the ecological point of view, water resources, soil protection and erosion, plant ecophysiology and settlement, and agronomy. It will be helpful to students, researchers, teachers, and anyone interested in any of these areas.

Molecular Mechanisms in Plant Adaptation by Roosa Laitinen Pdf

Plants are forced to adapt for a variety of reasons— protection, reproductive viability, and environmental and climatic changes. Computational tools and molecular advances have provided researchers with significant new insights into the molecular basis of plant adaptation. Molecular Mechanisms in Plant Adaptation provides a comprehensive overview of a wide variety of these different mechanisms underlying adaptation to these challenges to plant survival. Molecular Mechanisms in Plant Adaptation opens with a chapter that explores the latest technological advances used in plant adaptation research, providing readers with an overview of high-throughput technologies and their applications. The chapters that follow cover the latest developments on using natural variation to dissect genetic, epigenetic and metabolic responses of plant adaptation. Subsequent chapters describe plant responses to biotic and abiotic stressors and adaptive reproductive strategies. Emerging topics such as secondary metabolism, small RNA mediated regulation as well as cell type specific responses to stresses are given special precedence. The book ends with chapters introducing computational approaches to study adaptation and focusing on how to apply laboratory findings to field studies and breeding programs. Molecular Mechanisms in Plant Adaptation interest plant molecular biologists and physiologists, plant stress biologists, plant geneticists and advanced plant biology students.
