The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.
This account of the archaeology of a cave in southern New Mexico makes a dramatic contribution to the ongoing debate over how long human beings have lived in the Americas. The findings presented here show that human settlement may go back as far as 75,000 years before the present, whereas the long-accepted Clovis dates showed humans only about 12,000 years ago. MacNeish and his colleagues subjected the cave, its environs, and its contents to rigorous interdisciplinary investigation. The first section of this volume comprises their reports on the changing environment of the area. The second section concentrates on the excavation of the cave's layers, presenting the results of radiocarbon dating and describing the evidence of human occupation, including friction skin prints and human hair. The third section discusses the cultural implications of the materials recovered and suggests how the ancient peoples may have exploited the changing environment and developed different ways of life throughout the Americas before the time of Clovis man. No serious discussion of early inhabitants in the New World can disregard the findings presented in this monumental work of scholarship.
This text explores the natural history of Texas and more than 2900 springs in 183 Texas counties. It also includes an in-depth discussion of the general characteristics of springs - their physical and prehistoric settings, their historical significance, and their associated flora and fauna.
Although humans in the Southwest were hunter-gatherers for about 85 percent of their history, the majority of the archaeological research in the region has focused on the Formative period. In recent years, however, the amount of data on the Archaic period has grown exponentially due to the magnitude of cultural resource management projects in this region. The Archaic Southwest: Foragers in an Arid Land is the first volume to synthesize this new data. The book begins with a history of the Archaic in the Four Corners region, followed by a compilation and interpretation of paleoenvironmental data gathered in the American Southwest. The next twelve chapters, each written by a regional expert, provide a variety of current research perspectives. The final two chapters present broad syntheses of the Southwest: the first addresses the initial spread of maize cultivation and the second considers present and future research directions. The reader will be astounded by the amount of research that has been conducted and how all this information can be woven together to form a long-term picture of hunter-gatherer life.
