This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.

This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

A history of the relation of geology during the first 110 years of the US Geological Survey to the development of public-land, federal-science, and mapping policies and the development of mineral resources in the United States.

Ancient Knowledge Networks is a book about how knowledge travels, in minds and bodies as well as in writings. It explores the forms knowledge takes and the meanings it accrues, and how these meanings are shaped by the peoples who use it.Addressing the relationships between political power, family ties, religious commitments and literate scholarship in the ancient Middle East of the first millennium BC, Eleanor Robson focuses on two regions where cuneiform script was the predominant writing medium: Assyria in the north of modern-day Syria and Iraq, and Babylonia to the south of modern-day Baghdad. She investigates how networks of knowledge enabled cuneiform intellectual culture to endure and adapt over the course of five world empires until its eventual demise in the mid-first century BC. In doing so, she also studies Assyriological and historical method, both now and over the past two centuries, asking how the field has shaped and been shaped by the academic concerns and fashions of the day. Above all, Ancient Knowledge Networks is an experiment in writing about ‘Mesopotamian science’, as it has often been known, using geographical and social approaches to bring new insights into the intellectual history of the world’s first empires.

Drawing on a thousand years of European travel writing and mapmaking, Dym suggests that after centuries of text-based itineraries and on-the spot directions guiding travelers and constituting their reports, maps in the fifteenth century emerged as tools for Europeans to support and report the results of land and sea travel. With each succeeding generation, these linear journey maps have become increasingly common and complex, responding to changes in forms of transportation, such as air and motor car ‘flight’ and print technology, especially the advent of multi-color printing. This is their story.

One of the great seats of learning and repositories of knowledge in the ancient world, Alexandria, and the great school of thought to which it gave its name, made a vital contribution to the development of intellectual and cultural heritage in the Occidental world. This book brings together twenty papers delivered at a symposium held at the J. Paul Getty Museum on the subject of Alexandria and Alexandrianism. Subjects range from “The Library of Alexandria and Ancient Egyptian Learning” and “Alexander’s Alexandria” to “Alexandria and the Origins of Baroque Architecture.” With nearly two hundred illustrations, this handsome volume presents some of the world’s leading scholars on the continuing influence and fascination of this great city. The distinguished contributors include Peter Green, R. R. R. Smith, and the late Bernard Bothmer.
