Elements of Ecology

Benjamin/Cummings Pub. Co.

The book shows how the wartime alliance of engineers, scientists, and the military exemplified by MIT's Radiation Lab helped to transform research and development practice in the United States through the end of the Cold War period.
This book presents an organizational and social history of one of the foundational projects of the computer era: the development of the SAGE (Semi-Automatic Ground Environment) air defense system, from its first test at Bedford, Massachusetts, in 1951, to the installation of the first unit of the New York Air Defense Sector of the SAGE system, in 1958. The idea for SAGE grew out of Project Whirlwind, a wartime computer development effort, when the U.S. Department of Defense realized that the Whirlwind computer might anchor a continent-wide advance warning system. Developed by MIT engineers and scientists for the U.S. Air Force, SAGE monitored North American skies for possible attack by manned aircraft and missiles for twenty-five years. Aside from its strategic importance, SAGE set the foundation for mass data-processing systems and foreshadowed many computer developments of the 1960s. The heart of the system, the AN/FSQ-7, was the first computer to have an internal memory composed of "magnetic cores," thousands of tiny ferrite rings that served as reversible electromagnets. SAGE also introduced computer-driven displays, online terminals, time sharing, high-reliability computation, digital signal processing, digital transmission over telephone lines, digital track-while-scan, digital simulation, computer networking, and duplex computing. The book shows how the wartime alliance of engineers, scientists, and the military exemplified by MIT's Radiation Lab helped to transform research and development practice in the United States through the end of the Cold War period.

This book presents a comprehensive overview of all aspects of ecology, including evolution, ecosystems theory, practical applications, plants, animals, biogeochemical cycles, and global change. A new chapter discusses global environmental change, human impacts on the global carbon cycle, and the possible implications for the global climate system. Six "Ecological Application Essays" demonstrate to students the real world relevance of ecological concepts. For example, Part V, Population Interactions, discusses how a lack of mushrooms helped power the Industrial Revolution. Reflecting current changes in the field of ecology, the new edition incorporates more discussion of the evolutionary perspective on ecological systems. For anyone interested in ecology.

Elements of Ecology Update (4th Edition)

SMITH

Addison-Wesley

This book provides readers with a popular modular organization and an easy-to-read writing style that explains the basics of ecology. The authors have updated the Fifth Edition to reflect the current emphasis on the physical environment, global environmental change, and adaptation/evolution. As a result, there are new chapters, a new structure, and new topics found in the table of contents. These changes provide readers with an understanding of the principles governing the relationships between plants, animals, and other living organisms within their environment, and give them skills to critically evaluating public issues related to ecology. Abundant real-life examples illustrate and clarify the book's emphasis on understanding ecological patterns within an evolutionary framework. For instructors and students, or anyone interested in ecology.

Elements of Ecology (5th Edition)

The new Elements of Ecology Update, Fourth Edition, Learning Package includes the text by Robert and Tom Smith, and two brand new supplements at no extra price - the Ecology Place CD-Rom, a rich media supplement which contains 26 interactive field experiments and tutorials, and the Ecology Action Guide, a print supplement which provides information on topics such as environmental job opportunities, green groups, organizations, and sustainability.With its unique modular organization and striking four-color art program Elements of Ecology Update, Fourth Edition, Learning Package provides a clear introduction to ecology. Far reaching in its coverage, the Fourth Edition Update not only presents the principles of ecology but shows their relationship to today's most pressing environmental issues in a way that is meaningful to students. New Ecological Application essays synthesize concepts to illustrate their relevance to real-life problems. Chapter 26, Global Environmental Change has been revised to incorporate new research from this rapidly changing field. New Elements of Ecology Companion web site includes student and instructor resources geared specifically to the text.

Elements of Ecology Update: Hands-On Field Package (4th Edition)

This book presents a comprehensive overview of all aspects of ecology, including evolution, ecosystems theory, practical applications, plants, animals, biogeochemical cycles, and global change. This balanced approach has made Ecology and Field Biology, Sixth Edition the best-selling ecology book on the market. 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.
