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.
