Bats of the United States and Canada is the only complete and accessible guide to all forty-seven species of bats found in the region. Bats are among the world’s most fascinating creatures. The only mammals capable of true flight, these animals are marvels of evolution. A wide variety of species lives in the United States and Canada, ranging from the California leaf-nosed bat to the Florida bonneted bat, from the eastern small-footed bat to the northern long-eared Bat. Fact-filled and easy to use, this guide includes accurate range maps, detailed biological information, and useful identification tips. J. Scott Altenbach's stunning photographs accompany each species account, capturing the amazing diversity of these winged mammals. This guide also includes helpful information on the natural history of bats from across the globe. Bats today face ever-increasing danger from destruction of habitat, new technologies such as wind turbines, chemical toxicants, and devastating diseases like white-nose syndrome, which is killing millions of cave bats in the United States and Canada. The authors discuss these threats and others as well as the latest conservation efforts to protect bats around the world. Written by three of the world’s leading bat experts, this volume is the most comprehensive guide to the bat species of the United States and Canada available.
The Story of America’s First National River
Under the auspices of the 1938 Flood Control Act, the U.S. Corps of Engineers began to pursue an aggressive dam-building campaign. A grateful public generally lauded their efforts, but when they turned their attention to Arkansas’s Buffalo River, the vocal opposition their proposed projects generated dumbfounded them. Never before had anyone challenged the Corps’s assumption that damming a river was an improvement. Led by Neil Compton, a physician in Bentonville, Arkansas, a group of area conservationists formed the Ozark Society to join the battle for the Buffalo. This book is the account of this decade-long struggle that drew in such political figures as supreme court justice William O. Douglas, Senator J. William Fulbright, and Governor Orval Faubus. The battle finally ended in 1972 with President Richard Nixon’s designation of the Buffalo as the first national river. Drawing on hundreds of personal letters, photographs, maps, newspaper articles, and reminiscences, Compton’s lively book details the trials, gains, setbacks, and ultimate triumph in one of the first major skirmishes between environmentalists and developers.
Nature and People in the Louisiana Bayou Country
Louisiana’s bayous and their watersheds teem with cypress trees, alligators, crawfish, and many other life forms. From Bayou Tigre to Half Moon Bayou, these sluggish streams meander through lowlands, marshes, and even uplands to dominate the state’s landscape. In Bayou-Diversity, conservationist Kelby Ouchley reveals the bayou’s intricate web of flora and fauna. Through a collection of essays about Louisiana’s natural history, Ouchley details an amazing array of plants and animals found in the Bayou State. Baldcypress, orchids, feral hogs, eels, black bears, bald eagles, and cottonmouth snakes live in the well over a hundred bayous of the region. Collectively, Ouchley’s vignettes portray vibrant and complex habitats. But human interaction with the bayou and our role in its survival, Ouchley argues, will determine the future of these intricate ecosystems. Bayou-Diversity narrates the story of the bayou one flower, one creature at a time, in turn illustrating the bigger picture of this treasured and troubled Louisiana landscape.
Quail Management in Cattle Country
In this completely revised Texas A&M University Press edition, Guthery and coauthor Fidel Hernández have breathed new life into a classic work that for more than twenty years has been teaching biologists, managers, and ranchers to "think like a quail." Updated with the latest research on quail habitat management, predator control, and recent issues such as aflatoxin contamination, Hernández and Guthery help land stewards understand the optimum conditions for encouraging and sustaining quail populations while continuing to manage rangeland for cattle production. Written in a style that is entertaining and easy to read, this book is, in Guthery’s words, "meant to be kept on the dashboard of your pickup." More than 150 helpful photographs and figures, along with supporting tables, accompany the text. In his foreword to this edition of Beef, Brush, and Bobwhites, respected Texas wildlife photographer Wyman Meinzer writes of how the calls of a covey of bobwhites—or the unfortunate absence of those calls—can remind us "that wildlife and habitat conservation is directly proportional to the quality of stewardship that we bestow on the land."
This innovative volume is the first collective effort by archaeologists and ethnographers to use concepts and models from human behavioral ecology to explore one of the most consequential transitions in human history: the origins of agriculture. Carefully balancing theory and detailed empirical study, and drawing from a series of ethnographic and archaeological case studies from eleven locations—including North and South America, Mesoamerica, Europe, the Near East, Africa, and the Pacific—the contributors to this volume examine the transition from hunting and gathering to farming and herding using a broad set of analytical models and concepts. These include diet breadth, central place foraging, ideal free distribution, discounting, risk sensitivity, population ecology, and costly signaling. An introductory chapter both charts the basics of the theory and notes areas of rapid advance in our understanding of how human subsistence systems evolve. Two concluding chapters by senior archaeologists reflect on the potential for human behavioral ecology to explain domestication and the transition from foraging to farming.
Reflections from Colorado
The Barren Promise of Genetic Engineering
In 2001 the Human Genome Project announced that it had successfully mapped the entire genetic content of human DNA. Scientists, politicians, theologians, and pundits speculated about what would follow, conjuring everything from nightmare scenarios of state-controlled eugenics to the hope of engineering disease-resistant newborns. As with debates surrounding stem-cell research, the seemingly endless possibilities of genetic engineering will continue to influence public opinion and policy into the foreseeable future. Beyond Biotechnology: The Barren Promise of Genetic Engineering distinguishes between the hype and reality of this technology and explains the nuanced and delicate relationship between science and nature. Authors Craig Holdrege and Steve Talbott evaluate the current state of genetic science and examine its potential applications, particularly in agriculture and medicine, as well as the possible dangers. The authors show how the popular view of genetics does not include an understanding of the ways in which genes actually work together in organisms. Simplistic and reductionist views of genes lead to unrealistic expectations and, ultimately, disappointment in the results that genetic engineering actually delivers. The authors explore new developments in genetics, from the discovery of “non-Darwinian” adaptative mutations in bacteria to evidence that suggests that organisms are far more than mere collections of genetically driven mechanisms. While examining these issues, the authors also answer vital questions that get to the essence of genetic interaction with human biology: Does DNA “manage” an organism any more than the organism manages its DNA? Should genetically engineered products be labeled as such? Do the methods of the genetic engineer resemble the centuries-old practices of animal husbandry? Written for lay readers, Beyond Biotechnology is an accessible introduction to the complicated issues of genetic engineering and its potential applications. In the unexplored space between nature and laboratory, a new science is waiting to emerge. Technology-based social and environmental solutions will remain tenuous and at risk of reversal as long as our culture is alienated from the plants and animals on which all life depends.
