Book Description
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.

Book Description
The Sonoran Desert, a fragile ecosystem, is under ever-increasing pressure from a burgeoning human population. This ecological atlas of the region's plants, a greatly enlarged and full revised version of the original 1972 atlas, will be an invaluable resource for plant ecologists, botanists, geographers, and other scientists, and for all with a serious interest in living with and protecting a unique natural southwestern heritage. An encyclopedia as well as an atlas, this monumental work describes the taxonomy, geographic distribution, and ecology of 339 plants, most of them common and characteristic trees, shrubs, or succulants. Also included is valuable information on natural history and ethnobotanical, commercial, and horticultural uses of these plants. The entry for each species includes a range map, an elevational profile, and a narrative account. The authors also include an extensive bibliography, referring the reader to the latest research and numerous references of historical importance, with a glossary to aid the general reader. Sonoran Desert Plants is a monumental work, unlikely to be superseded in the next generation. As the region continues to attract more people, there will be an increasingly urgent need for basic knowledge of plant species as a guide for creative and sustainable habitation of the area. This book will stand as a landmark resource for many years to come.

Book Description
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.
