For eighty-seven miles, the swift and shallow Blanco River winds through the Texas Hill Country. Its water is clear and green, darkened by frequent pools. Wes Ferguson and Jacob Botter have paddled, walked, and waded the Blanco. They have explored its history, people, wildlife, and the natural beauty that surprises everyone who experiences this river. Described as “the defining element in some of the Hill Country’s most beautiful scenery,” the Blanco flows both above and below ground, part of a network of rivers and aquifers that sustains the region’s wildlife and millions of humans alike. However, overpumping and prolonged drought have combined to weaken the Blanco’s flow and sustenance, and in 2000—for the first time in recorded history—the river’s most significant feeder spring, Jacob’s Well, briefly ceased to flow. It stopped again in 2008. Then, in the spring of 2015, a devastating flood killed twelve people and toppled the huge cypress trees along its banks, altering not just the look of the river, but the communities that had come to depend on its serene presence. River travelers Ferguson and Botter tell the remarkable story of this changeable river, confronting challenges and dangers as well as rare opportunities to see parts of the river few have seen. The authors also photographed and recorded the human response to the destruction of a beloved natural resource that has become yet another episode in the story of water in Texas.

WATER RESOURCES AND ENVIRONMENT provides a detailed introduction to the full range of advanced, multidisciplinary techniques used in the study of water resources from understanding individual aquifers to the protection and management of water in a sustainable way, compatible with the preservation of the environment. Based on a masters course from UNESCO’s International Hydrological Program, this textbook is accompanied by color figures and graphics, illustrating clearly the content of the text and showing real examples from the field. Each chapter also contains a list of exercises and practical activities as well as case studies.

Pesticides in Stream Sediment and Aquatic Biota

Distribution, Trends, and Governing Factors

More than 20 years after the ban of DDT and other organochlorine pesticides, pesticides continue to be detected in air, rain, soil, surface water, bed sediment, and aquatic and terrestrial biota throughout the world. Recent research suggests that low levels of some of these pesticides may have the potential to affect the development, reproduction, and behavior of fish and wildlife, and possibly humans. Pesticides in Stream Sediment and Aquatic Biota: Distribution, Trends, and Governing Factors assesses the occurrence and behavior of pesticides in bed sediment and aquatic biota-the two major compartments of the hydrologic system where organochlorine pesticides are most likely to accumulate. This book collects, for the first time, results from several hundred monitoring studies and field experiments, ranging in scope from individual sites to the entire nation. Comprehensive tables provide concise summaries of study locations, pesticides analyzed, and study outcomes. Comprehensive and extensively illustrated, Pesticides in Stream Sediment and Aquatic Biota: Distribution, Trends, and Governing Factors evaluates the sources, environmental fate, geographic distribution, and long-term trends of pesticides in bed sediment and aquatic biota. The book focuses on organochlorine pesticides, but also assesses the potential for currently used pesticides to be found in bed sediment and aquatic biota. Topics covered in depth include the effect of land use on pesticide occurrence, mechanisms of pesticide uptake and accumulation by aquatic biota, and the environmental significance of observed levels of pesticides in stream sediment and aquatic biota.

This book reviews wildlife management and conservation in Central and South America. The book discusses the threats to biodiversity in this area including habitat fragmentation, development, ranching, tourism as well as hunting. The book contains contributions from many local Latin American authors who work there daily and are exposed to the numerous and unique issues that need to be taken into account when talking about conservation in Central and South America.
