This book was released on 1968 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report is the outcome of a symposium on the ecology of the forest/savanna boundary. The papers presented at the meeting have been cut and edited so that a theme is presented rather than a series of papers. In the introduction, the problems involved in savanna classification and the ambiguity of terminology are discussed, types of savanna found in different parts of the world described, and methods of examination analysed. The section is concluded by a description of the field trip made by the Symposium members, during which many of the differences in attitude were seen in a fresh light. A second chapter is concerned with savanna/forest boundaries held stable by factors of the physical environment; here the roles of flooding and desiccation, climate, soils and geomorphology are examined. In the third chapter the authors discuss stable boundaries resulting from human action. Fire and the role of domesticated grazing animals are seen as the major factors. The subject of the fourth section is the boundary when not in equilibrium. Many factors are examined in different parts of the world including soil, wild animals, fire, palaeoclimatology and man. An evaluation is made of the use of palynological and historical data. (Author).

Download or read book Ecotones Between Forest and Grassland written by Randall W. Myster and published by Springer Science & Business Media. This book was released on 2012-07-10 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotones are dynamic over-lapping boundary areas where major terrestrial biomes meet. As past studies have shown, and as the chapters in this book will illustrate, their structure, size, and scope have changed considerably over the millennia, expanding and shrinking as climate and/or other driving conditions, also changed. Today, however, many of them are changing at a rate not seen for a long time, perhaps largely due to climate change and other human-induced factors. Indeed ecotones are more sensitive to climate change than the biomes on either side, and thus may serve as critical early indicators of future climate change. As ecotones change, they also redefine the limits of the biomes on either side by altering their distributions of species because, in addition to their own endemic species, any ecotone will also have species from both adjoining biomes. Consequently, they may also be places of high levels of species interaction, serving as active evolutionary laboratories, which generate new species that then migrate back into adjacent biomes. Ecotones Between Forest and Grassland explores how these ecotones have changed in the past, how they are changing today, and how they are likely to change in the future. The book includes chapters from around the world with a special focus on South American and Neotropical ecotones.
Download or read book Fire Ecology and Management Past Present and Future of US Forested Ecosystems written by Cathryn H. Greenberg and published by Springer Nature. This book was released on 2021-10-01 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume presents original scientific research and knowledge synthesis covering the past, present, and potential future fire ecology of major US forest types, with implications for forest management in a changing climate. The editors and authors highlight broad patterns among ecoregions and forest types, as well as detailed information for individual ecoregions, for fire frequencies and severities, fire effects on tree mortality and regeneration, and levels of fire-dependency by plant and animal communities. The foreword addresses emerging ecological and fire management challenges for forests, in relation to sustainable development goals as highlighted in recent government reports. An introductory chapter highlights patterns of variation in frequencies, severities, scales, and spatial patterns of fire across ecoregions and among forested ecosystems across the US in relation to climate, fuels, topography and soils, ignition sources (lightning or anthropogenic), and vegetation. Separate chapters by respected experts delve into the fire ecology of major forest types within US ecoregions, with a focus on the level of plant and animal fire-dependency, and the role of fire in maintaining forest composition and structure. The regional chapters also include discussion of historic natural (lightning-ignited) and anthropogenic (Native American; settlers) fire regimes, current fire regimes as influenced by recent decades of fire suppression and land use history, and fire management in relation to ecosystem integrity and restoration, wildfire threat, and climate change. The summary chapter combines the major points of each chapter, in a synthesis of US-wide fire ecology and forest management into the future. This book provides current, organized, readily accessible information for the conservation community, land managers, scientists, students and educators, and others interested in how fire behavior and effects on structure and composition differ among ecoregions and forest types, and what that means for forest management today and in the future.

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.
