The Yanoama are one of the most numerous remaining aboriginal populations of the South American tropical forests, and their large territory constitutes a significant culture region. Although other scholars (anthropologists, geneticists, linguists) have studied this contemporary "neolithic" population, this is the first geographic study of the Yanoama. It is also the only book to focus on the Yanoama highland core area—the Parima massif—and it is the first study to analyze Yanoama horticulture as an integral part of their ecosystem. The author is concerned principally with the spatial dimension as developed in Yanoama culture, with the spatial patterns of functioning systems, and with Yanoama ecology in this highland habitat. The natural environment is viewed, not as a cultural determinant, but as part of the total ecosystem. Livelihood activities constitute a major organizing theme and, among these, gardening receives the most attention. Frequently classified as a nomadic hunter-gatherer group, the Yanoama are found to have a deep-seated horticultural tradition, and many new data on this tradition are presented. As this study reveals, the Yanoama have created and maintained a cultural landscape that bears their distinctive stamp.

In 1971 the International Society of Tropical Ecology and the International Association for Ecology held a meeting on Tropical Ecology, with an emphasis on organic production in New Delhi, India. At this meeting a Working Group on Tropical Ecology was organized, consisting of K. C. Misra (India), F. Malaisse (Zaire), E. Medina (Venezuela) and F. Golley (U.S.A.). The object of this Working Group was to stimulate interaction between tropical ecologists through future scientific meetings and other exchanges and communications. A second meeting of ISTE and INTECOL was held in Caracas, Venezuela in 1973, under the direction of Medina and Golley and sponsored by the Depart ment of Ecology, Institute Venezolano Investigaciones Cientificas (lVIC). The basic structure of the meeting was provided by series of invited papers which considered topics of special interest from both an applied and theoretical view. These included physiological ecology (Pannier), populations (Rabinovich), tropical savannas (Lamotte), rivers (Sioli), estuaries (Rodriguez), and island ecosystems (Mueller-Dombois). Contributed papers considered details of these and other ecological topics, including the application of ecology to human problems. The present volume includes the invited papers listed above and a sampling of contributed papers which together illustrate the trends of research in tropical ecology. The papers show that tropical ecology is a vigorous subject of research. While the papers in this volume do not provide reviews of all the topics of study in tropical ecology, they do present authoritative statements on progress in the major subject in the field.

This book presents a comprehensive and critical historical overview of the role played by the US as a developer and consumer of tropical nature. -- Distributed by Syndetic Solutions, LLC.

The Institute of Ecology (TIE) was organized to provide a mech anism for addressing ecological and environmental issues that were beyond the special interests of ecology as a profession. One method of evaluating such issues is the workshop, and this report describes the results of the third TIE workshop on a major environmental subject. The ecology of tropical regions is of interest to all the inhabitants of the biosphere. The tropics provide mankind with both the opportunity for and the challenge of essential resources, land for settlement and development, and waters for numerous uses. Moreover, they provide examples of misuse of the landscape, fragility of ecological systems, and serious environmental problems. Unfortunately, the study of the ecology of the tropics has not kept pace with the ecology of other regions. The purpose of this report, therefore, is to determine the research approaches that will lead to advances in our theoretical un derstanding of tropical systems and, more importantly, in the applica tion of that knowledge to human problems. Although the principal focus of the report is on the neotropics, it will be useful to the full spectrum of persons concerned with the tropics around the world government officials, sCientists, students of ecology, and others. TIE is especially pleased to thank the numerous scientists and ad ministrators who participated in the workshop and who contributed to this report. Arthur D.
