Book Description
Follow along as a researcher observes and makes journal entries about their field trip through the Sonoran Desert ecosystem. Outstanding photographs highlight the animals, plants, and people that inhabit this hot desert that straddles the United States and Mexico. Simple graphs show how much the desert has changed, and the final report describes efforts being made to preserve it. Teacher's guide available.

Book Description
Mariana is a third grader living in Las Cruces, New Mexico at the northern fringe of the Chihuahuan Desert. One day her class visits Chihuahuan Desert Nature Park to hike to the top of an extinct volcano and see the plant and animal life that is special to this desert. Led by Dr. Whitford, the nature park scientist, the children are challenged to find as many signs of animals living along the trail as they can. Mariana is amazed at all the life around her that was difficult to see at first glance. Adapting to the desert environment, many animals were camouflaged or sought shelter from the sun in burrows. At last atop the volcano, Dr. Whitford tells the children that “This is a great example of an ecosystem that has shifted.” Once grassland, the landscape is now mostly covered in shrubs like creosote bush and mesquite. Suddenly a storm comes up with little warning, and the children rush back to their bus. As the rain subsides the bus driver delivers the unwelcome news that the bus will have to be pulled out of the now muddy road. While waiting for help the children get out of the bus and head for a nearby Playa, a special kind of shallow lake that is formed after a heavy rain. As Mariana wades through the Playa she notices small animals in the water, and scoops one up. Dr. Whitford identifies it as a tadpole shrimp, animals that hatch only when water fills the lakes. At last the bus is pulled out of the mud by a rancher’s tractor, and Mariana returns home to write to her friends about her day in the desert.

Book Description
China has been experiencing extraordinary economic growth for over two decades. Behind the remarkable statistics, however, it is facing a pressing issue: balancing its economic development needs with protecting its environmental resources. The environmental issue in China has a profound impact on the rest of the world as well, in such concerns as global warning and ethical and legal considerations about environmental enforcement. This book covers a broad range of topics, from specific environmental assessments in key sectors (i.e. desertification) to the policy implications of China's entry into the WTO. The contributors include scholars, government officials, business consultants, environmental science and technology experts, and others based in China and the United States. Sharing perspectives that reflect their diverse backgrounds, these experts offer valuable insights for handling the emerging opportunities and challenges of doing business in China.

Book Description
"Provides interesting and thought-provoking reading and is highly recommended to anyone interested in desert ecosystems or community ecology. The book . . . should serve as an inspiration to many for future research."—Journal of Biogeography "This book is not just about deserts; it is an update of the contributions that research in desert systems is making to community ecology. . . This book will provide a useful reference for desert ecologists, as well as indicate critical directions where progress needs to be made."—Ecology "This important book fills a significant gap in previous syntheses by presenting a detailed series of reviews of current understanding of community patterns and structure in desert environments. . . . Each chapter is thorough and well written and . . . closes with a discussion of suggested future research. . . . [T]hese ideas will do much to focus interest on the importance of desert systems in understanding community. Thus, this book has interest well beyond desert ecologists alone."—BioScience "Valuable reading and reference for ecology students, teachers and researchers."—Quarterly Review of Biology

Book Description
The fact that approximately one-third of the world's land mass is arid desert may be congenial for the camel and the cactus, but not for people. Nevertheless, well over half a billion people, or 15% of the world's population live in arid desert areas. If the world's population were distributed evenly over the land surface, we would expect to find about 30% of the population inhabiting arid desert areas. Does the fact that 'only' 15% of the world's population live in an arid desert environment reflect the harshness of the environment? Or is it a testimony to the adaptability and ingenuity of mankind? Do we view the glass as half-full? Or half-empty? The contributors to Desert Development: Man and Technology in Sparselands adopt the position that the cup is half-full and, in fact, could be filled much more. Indeed, many arid desert zones do thrive with life, and given appropriate technological develop ment, such areas could support even greater popUlations. While the dire Malthusian prediction that rapid world population growth exceeds the carrying capacity of existent resource systems has gained popularity (typified by the 1972 Club of Rome book, Limits to Growth), there is a growing body of serious work which rejects such pessimistic 'depletion' models, in favor of models which are mildly optimistic.

Book Description
Published by the American Geophysical Union as part of the Water Science and Application Series, Volume 9. Groundwater recharge, the flux of water across the water table, is arguably the most difficult component of the hydrologic cycle to measure. In arid and semiarid regions the problem is exacerbated by extremely small recharge fluxes that are highly variable in space and time. --from the Preface Groundwater Recharge in a Desert Environment: The Southwestern United States speaks to these issues by presenting new interpretations and research after more than two decades of discipline-wide study. Discussions ondeveloping environmental tracers to fingerprint sources and amounts of groundwater at the basin scalethe critical role of vegetation in hydroecological processesnew geophysical methods in quantifying channel rechargeapplying Geographical Information System (GIS) models to land surface processescoupling process-based vadose zone to groundwater modeling, and more make this book a significant resource for hydmlogists, biogeoscientists, and geochemists concerned with water and water-related issues in arid and semiarid regions.
