North American deserts-lands of little water-have long been home to a surprising diversity of aquatic life, from fish to insects and mollusks. With European settlement, however, water extraction, resource exploitation, and invasive species set many of these native aquatic species on downward spirals. In this book, conservationists dedicated to these creatures document the history of their work, the techniques and philosophies that inform it, and the challenges and opportunities of the future. A precursor to this book, Battle Against Extinction, laid out the scope of the problem and related conservation activities through the late 1980s. Since then, many nascent conservation programs have matured, and researchers have developed new technologies, improved and refined methods, and greatly expanded our knowledge of the myriad influences on the ecology and dynamics of these species. Standing between Life and Extinction brings the story up to date. While the future for some species is more secure than thirty years ago, others are less fortunate. Calling attention not only to iconic species like the razorback sucker, Gila trout, and Devils Hole pupfish, but also to other fishes and obscure and fascinating invertebrates inhabiting intermittent aquatic habitats, this book explores the scientific, social, and political challenges of preserving these aquatic species and their habitats amid an increasingly charged political discourse and in desert regions characterized by a growing human population and rapidly changing climate.

Perfect for the budding paleontologist, this book brings to life animals that lived long ago. With clear text and engaging questions, a full range of fossils from microscopic insects to gigantic prehistoric mammals is examined. Students are encouraged to discuss the idea of "living fossils" and examine how fossilized animals have adapted into life forms still present today.

A comprehensive review of dryland climates and their relationship to the physical environment, hydrology, and inhabitants. Chapters are divided into five major sections on background meteorology and climatology; the nature of dryland climates in relation to precipitation and hydrology; the climatology and climate dynamics of the major dryland regions on each continent; and life and change in the world's drylands. It includes key topics such as vegetation, geomorphology, desertification, micro-habitats, and adaptation to dryland environments. This interdisciplinary volume provides an extensive review of the primary literature (covering nearly 2000 references) and the conventional and satellite datasets that form key research tools for dryland climatology. Illustrated with over 300 author photographs, it presents a unique view of dryland climates for a broad spectrum of researchers, environmental professionals and advanced students in climatology, meteorology, geography, environment science, earth system science, ecology, hydrology and geomorphology.

There are many urgent problems in arid land hydrogeology and it is these issues which are tackled in this volume on desert environments. The UAE-Japan symposia provide a venue for the exchange of expertise, confronting such problems as purification, usage and management of groundwater, the assessment and protection of sustainable water resources, and soil enhancement techniques for moisture control in arid lands. The hope is that a better understanding of dryland environment, combined with innovative solutions and technologies, will contribute to the greening of desert lands.

The papers in this volume cover topics in the field of geoengineering in arid lands. Topics include: coupled thermo-hydro-mechanical processes in geomechanics; sediment formation in marine environment; soil stability and stabilization techniques; and unsaturated soil behaviour and modelling.
