Synopsis Survival Strategies of Annual Desert Plants by : Yitzchak Gutterman
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.

Synopsis Seed Germination in Desert Plants by : Yitzchak Gutterman
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.

Synopsis Life at Extremes by : Elanor Bell
From arid deserts to icy poles, outer space to the depths of the sea, this exciting new work studies the remarkable life forms that have made these inhospitable environments their home. Covering not only micro-organisms, but also higher plants and animals such as worms, fish and polar plants, this book details the ecological, biological and biogeochemical challenges these organisms face and unifying themes between environments. Equally useful for the expert, student and casual scientific reader, this book also explores the impact of climate change, rapid seasonal changes and pollution on these extraordinary creatures.

Synopsis The Encyclopedia of Seeds by : J. Derek Bewley
This is the first scholarly reference work to cover all the major scientific themes and facets of the subject of seeds. It outlines the latest fundamental biological knowledge about seeds, together with the principles of agricultural seed processing, storage and sowing, the food and industrial uses of seeds, and the roles of seeds in history, economies and cultures. With contributions from 110 expert authors worldwide, the editors have created 560 authoritative articles, illustrated with plentiful tables, figures, black-and-white and color photographs, suggested further reading matter and 670 supplementary definitions. The contents are alphabetically arranged and cross-referenced to connect related entries.

Synopsis Desert Plants by : Kishan Gopal Ramawat
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).

Synopsis Seedling Ecology and Evolution by : Mary Allessio Leck
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.

Synopsis Microbiology of Hot Deserts by : Jean-Baptiste Ramond
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.
