Download or read book Subsistence and Survival written by Timothy P. Bayliss-Smith and published by Elsevier. This book was released on 2016-01-26 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: Subsistence and Survival: Rural Ecology in the Pacific covers the ecology of man's environment, man's use and perception of biological resources, and the physiology and health of the human organism itself. The geographical range of this text extends from the glaciated uplands of Papua New Guinea, through the montane forests and grasslands of the Highlands, into the coastal jungles, and across to the smaller islands and atolls of the South West Pacific. This book is organized into five parts encompassing 14 chapters. The first part deals with the theory and applications of human ecology. The next part considers first the International Biological Program in New Guinea concerning the link between human ecology and biomedical research. This part also explores the nutritional adaptation among the Enga and in Melanesia, and then introduces the principles of environmental health engineering as human ecology. The subsequent two parts highlight the impact of human activities on the environment, with an emphasis on the association between environmental exploitation and human subsistence. The final part discusses the relevance of self-subsistence communities for world ecosystem management. This book will be of great value to anthropologists, geographers, human biologists, nutritionists, botanists, and public health engineers.

Available in PDF, EPUB and Kindle. Book excerpt: First Published in 2011. Latin America today is similar to Canada in the early 1900s-a sleeping giant, basically underpopulated, whose potential rests on the exploitation of enormous land, forest, mineral, and water reserves. This study, carried out over the period 1967-69, has involved travel throughout much of Latin America north of the Tropic of Capricorn and discussions with people in many different fields, including highway construction, forestry, colonization, and agricultural industries in the forest frontier regions and capital cities of the continent. The collection of data required about twelve months of the author in the field.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Productivity and Herbivory in High and Low Diversity Tropical Successional Ecosystems in Costa Rica written by Becky Jean Brown and published by . This book was released on 1982 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Above-qcound net primary productivity (NPP) , herbivory and vegetation structural characteristics were measured in high and low diversity successional and agricultural ecosystems at a wet tropical site near Turrialfca, Costa Bica. Insecticide and defoliation experiments were performed to evaluate the effects of herbivory on NPP in high and low diversity ecosystems. The four experimental ecosystems were enriched succession (natural regeneration augmented by propagule additions) , natural succession (control) , successional mimic (an ecosystem with investigator-controlled species composition designed to imitate natural succession), and successional monoculture (two naize crops followed by cassava) . Plant species richness and leaf area index (LAI) were highest in the enriched, high in the natural succession, intermediate in the miiiiic, and low in the monoculture at 1.5 yr.
