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 The Tropical Rain Forest written by Marius Jacobs and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, tropical forests have received more attention and have been the subject of greater environmental concern than any other kind of vegetation. There is an increasing public awareness of the importance of these forests, not only as a diminishing source of countless products used by mankind, nor for their effects on soil stabilization and climate, but as unrivalled sources of what today we call biodiversity. Threats to the continued existence of the forests represent threats to tens of thousands of species of organisms, both plants and animals. It is all the more surprising, therefore, that there have been no major scientific accounts published in recent years since the classic handbook by Paul W. Richards, The Tropical Rain Forest in 1952. Some excellent popular accounts of tropical rain forests have been published including Paul Richard's The Life of the Jungle, and Catherine Caulfield's In the Rainforest and Jungles, edited by Edward Ayensu. There have been numerous, often conflicting, assessments of the rate of conversion of tropical forests to other uses and explanations of the underlying causes, and in 1978 UNESCO/UNEPI FAO published a massive report, The Tropical Rain Forest, which, although full of useful information, is highly selective and does not fully survey the enormous diversity of the forests.

Download or read book Tropical Forests and Climate written by N. Myers and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical forests affect climate, and the removal of the forests will change climate. Or not? This book discusses basic questions on how far, if at all, tropical deforestation leads to climatic change. The question of this uncertainty is particularly addressed. One important consequence of the uncertainties of whether deforestation affects climate is how scientific findings best illuminate the policy-making process.

Download or read book Genes Enzymes and Populations written by Adrian Srb and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume includes the large majority of papers given at the symposium entitled "Fundamental Approaches to Plant and Animal Improvement," held at Cali, Colombia, in November, 1972. The primary focal points were on various genetic mechanisms, including gene action and mutation, the development of phenotypic attributes, and on evolution, including that controlled by man for agricultural purposes. In fact, very little referring in any particular way to animal improvement was included, while a great deal of attention was paid to higher plants and to microorganisms. On the other hand, both the population genetics of insects and insect control were considered. Thus Genes, Enzymes, and Populations, the title given to this published work, seems to me to represent somewhat more fairly the contents than does the original symposium title. Given the intent of the symposium, which is expressed in the original title, the published record cannot be expected to be a neatly packaged presentation of some highly defined subject matter. Indeed the diverse subjects represent some, but by no means all, of the varied and dynamic scientific activities that need to be components in the improvement and production of agriculturally Significant plants at a time when world populations are rapidly increasing and shortages of food occurring. In any case, the organizers of the symposium wisely decided that considerations of environment as well as of genetics should be introduced into the thinking of the group and that physiology and molecular biology could not be ignored.

Interrelationship Between Insects and Plants is a rare and expansive look at the intertwining of these two vastly different species. Its aim is to summarize in a simple and understandable way the basis of food selection among insects, and to review the various sides of their relationships with plants.
Download or read book Biodiversity and Domestication of Yams in West Africa written by Roland Dumont and published by Editions Quae. This book was released on 2006-07-17 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of yam domestication practices among smallholders has provided an insight into how farmers exploit wild plant genetic resources so as to adapt them to agriculture. This book describes the domestication operations leading to Dioscorea rotundata yams in Africa. The biodiversity of these yams and of their wild relatives is investigated, and the authors put forward hypotheses to explain the phenotypic changes resulting from smallholder practices. These hypotheses could be possible lines of research for breeders.

Download or read book The Archaeology of Africa written by Bassey Andah and published by Routledge. This book was released on 2014-05-22 with total page 900 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa has a vibrant past. It emerges from this book as the proud possessor of a vast and highly complicated interweaving of peoples and cultures, practising an enormous diversity of economic and social strategies in an 2xtraordinary range of environmental situations. At long last the archaeology of Africa has revealed enough of Africa's unwritten past to confound preconceptions about this continent and to upset the picture inferred from historic written records. Without an understanding of its past complexities, it is impossible to grasp Africa's present, let alone its future.
