North American deserts – lands of little water – have long been home to a surprising diversity of aquatic life, from fish to insects and molluscs. With European settlement, however, water extraction, resource exploitation, and invasive species set many of these native aquatic species on downward spirals. In Standing between Life and Extinction, 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.

"This book should appeal to anyone broadly interested in conservation and management of water resources, and specifically to conservation scientists, natural resource managers, and fish biologists. There are strong historical threads woven throughout the chapters, and it serves both as a tribute to pioneering legends of early desert fish conservation and a synthesis of ongoing work that reveals successes, failures, and challenges in the face of human populations expanding into arid regions, the increasing conflicts over exploitation of water and land, and the overriding and worsening impacts of human-mediated climate change. The breadth of topics presented and synthesis of complex research outcomes as applied to conservation challenges are impressive. A valuable addition to the conservation literature that will be read widely and cited extensively."
