The Encyclopedia of Caves and Karst Science contains 350 alphabetically arranged entries. The topics include cave and karst geoscience, cave archaeology and human use of caves, art in caves, hydrology and groundwater, cave and karst history, and conservation and management. The Encyclopedia is extensively illustrated with photographs, maps, diagrams, and tables, and has thematic content lists and a comprehensive index to facilitate searching and browsing.

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.

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.

The aim of this edited volume is to introduce the scientific community to paleoenvironmental studies of estuaries, to highlight the types of information that can be obtained from such studies, and to promote the use of paleoenvironmental studies in estuarine management. Readers will learn about the the application of different paleoecological approaches used in estuaries that develop our understanding of their response to natural and human influences. Particular attention is given to the essential steps required for undertaking a paleoecological study, in particular with regard to site selection, core extraction and chronological techniques, followed by the range of indicators that can be used. A series of case studies are discussed in the book to demonstrate how paleoecological studies can be used to address key questions, and to sustainably manage these important coastal environments in the future. This book will appeal to professional scientists interested in estuarine studies and/or paleoenvironmental research, as well as estuarine managers who are interested in the incorporation of paleoenvironmental research into their management programs.
