Book Description
All over the planet, organisms of many species are appearing outside of their natural habitatsÑoften carried by that particularly peripatetic species Homo sapiens. This book marks the first comprehensive attempt to address problems posed by expanding populations of exotic plant and animal species in the Sonoran Desert and adjacent grasslands and riparian areas. It describes the arrival and spread of non-native species as diverse as rats and saltcedar, covering both their impacts and the management of those impacts. It is estimated that as much as 60 percent of the vegetative cover of the Sonoita Creek-Patagonia Reserve, the first Nature Conservancy area designated in Arizona, is dominated by exotic plants, and that introduced fish pose a recurrent threat to the native fish of that area. Meanwhile at the Grand Canyon, invasives such as tamarisk, red brome, carp, and catfish are pervasive either in the Colorado River or in the patches of desert scrub along its shores. Throughout the Sonoran Desert and adjacent areas, from islands in the Sea of CortŽs to desert grasslands, some six hundred species of non-native plants and animals have become established, with bullfrogs and Mediterranean grasses now common where they once never existed. The book brings together contributors from academia, government, and nonprofit organizations, including such experts as Gary Paul Nabhan, Richard Mack, and Alberto Bœrquez-Montijo. They review historic and even prehistoric origins of non-native speciesÑnot only exotic plants, amphibians, and mammals but also insects, fish, and birds. They then examine significant problems in each major subregion and ecosystem and discuss control efforts. The volume contains the first compiled list of more than 500 naturalized exotic species in the Sonoran region. Invasive species issues are rapidly emerging as major environmental concerns both locally and worldwide. This book will assist professionalsÑecologists, conservation biologists, and policy makersÑinvolved in invasive species control in the Southwest and will be a rich resource for all concerned with protecting native species and their habitats.

Book Description
"Leading experts in geography, biology, botany, zoology, and geoscience present new research on the desert grassland and review a vast amount of earlier work. They reveal that present-day grasses once grew in the ice age forests that existed in these areas before the climate dried and the trees vanished, and how the intensity and frequency of fire can influence the plant and animal species of the grassland.

Book Description
This book provides complete coverage of all aspects of the study of all fossil palynomorphs yet studied. It is a profusely illustrated treatment. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks. Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.

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.
