Deserts provide a harsh and inhospitable environment for plants and animals, and the ecosystem is correspondingly fragile and prone to disruption by a variety of external factors. The Mojave Desert is a winter-rainfall desert, experiencing drought in the summer months, and occasional rain during the cooler winter months. For many years, it has attracted the attention of ecologists and conservation biologists concerned to maintain the unique status of this region. This book provides a broad overview of plant and animal ecology in the Mojave Desert, presented with a focus on data from Rock Valley, Nevada. The data from many major research projects is synthesized into a description of community structure and dynamics in desert ecosystems.
