We've shared our lives with dogs for thousands of years, but they still act in ways that baffle us. To help us understand them better, Dr. Stanley Coren, the undisputed expert on dog behavior, intelligence, and training, tells the story of how dogs evolved over time into the myriad forms and breeds we love today. Not simply domesticated wolves, dogs are actually much more complex than wild canines; their ability to adapt to a man-made world is far more flexible, their personalities far more diverse. Fascinating findings reveal which breeds were bred to become more dominant, affectionate, cooperative, or even dangerous. This practical, surprising book also presents -- for the first time -- the "Dog Behavior Inventory," a simple, fun test based on the personality-profiling questionnaires used in human psychological studies that you can administer to your own dog to get a detailed picture of his personality and how he compares to other members of his breed. Then, using the findings of the U.S. Army's once- classified studies of "Superdogs," you can train your pet to become a real-life equivalent of Lassie and Rin Tin Tin -- a dog who is not disturbed, angered, or frightened by anything. Filled with the entertaining anecdotes and scientific data that Dr. Coren's avid followers have come to expect and enjoy, this uniquely complete guide to dog psychology can help you to select a new companion and to understand and communicate better with your old friend.

This volume contains material first presented at an international workshop on the 'Use of Microorganisms to Combat Pollution', held in Israel, May 10--18, 1992. The workshop was sponsored by the Bat-Sheva de Rothschild Foundation for the Advancement of Science and included microbiologists, biochemists and geneticists from universities, environmental agencies and the military. Each of the contributors to this volume is an ack nowledged expert on the treatment of one or more types of pollution using microorganisms or their enzymes. This book differs from most published symposia proceedings in the breadth of coverage of each subject. Most of the chapters are divided into three parts: (a) A general presentation of the source and toxicity of the pollutant, (b) a review of the current state-of-the-science on the biodegradation of that pollutant and (c) the authors' unique research experiences on the problem. In several examples, the authors have presented data from both laboratory studies and field trials. Thus, the book contains not only the theoretical background on the biodegradation of pollutants, but also practical experiences in applying this knowledge to solving significant pollution problems.

The Negev , first published over a decade ago, told the story of some twenty years of study of southern Israel's desert. It synthesized the findings of botanists, geologists, soil scientists, agronomists, archaeologists, historians, and engineers and told how the applications of their work produced an agricultural surplus in this forbiddingly dry, hot region. , Now Michael Evenari has amplified the book with data from another decade of work. He describes the efforts at a new farm at Wadi Mashash, extends the weather data another ten years, presents further work on the adaptations of plants and animals to desert conditions, and takes a much deeper look at the historical precedents for the method of runoff agriculture, which has made the desert bloom.
