Download or read book Slope Channel Coupling as a Factor in the Evolution of Mountains written by Małgorzata Wistuba and published by Springer. This book was released on 2014-07-29 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, coupling between the delivery of slope material into valley floors and river erosion is considered to be a factor in the evolution of mid-altitude, forested mountains. Analyses of slope-channel interactions were made in ten small catchments with particular emphasis on landsliding-erosion feedback. An original, new dendrogeomorphic approach was applied to determine the cyclic occurrence of landsliding and erosion during recent decades. The results of dendrochronological studies show that the processes studied are strongly interdependent. Fluvial erosion can trigger landsliding by undermining slope bases. Landsliding can intensify erosion by delivering slope material into valley floors. The results of dendrochronological studies have permitted a better understanding of the relief observed in areas where landslides and erosion are coupled. A scheme was established which describes the importance of coupling in the evolution of mid-mountain landscape.
Download or read book The Conservation Atlas of Tropical Forests written by Caroline Harcourt and published by Macmillan Reference USA. This book was released on 1996 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This final volume in the The Conservation Atlas of Tropical Forests covers the Americas. It provides an up-to-date overview of the status of rain forests in South America, Central America, and the Caribbean. Following the format of the two previous volumes The Conservation Atlas of Tropical Forests: Asia and the Pacific (1991) and The Conservation Atlas of Tropical Forests: Africa (1992), the atlas is divided into two parts. Part I introduces and discusses the complex interrelated issues in the regions that are involved in both deforestation as well as conservation of the tropical forests. Included are discussions on the history of the forests, agricultural colonization policies and deforestation, conservation polices for plants and wildlife, protected areas, and the future of the tropical forests. Part II is a detailed and well referenced country-by-country analysis of conservation status and trends. Four-colour maps have been compiled from satellite and radar imagery, aerial photography, and the latest information provided by forestry departments and development agencies.

Download or read book The Conservation Atlas of Tropical Forests written by International Union for Conservation of Nature and Natural Resources and published by Macmillan Reference USA. This book was released on 1992 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa's forests are being depleted at a faster rate than of any other continent. A major increase in the population growth rate began after World War II and it is now running at an annual rate of 2.9 per cent, resulting in massive demands for agricultural land, water, fuelwood and other products. There is no simple answer to environmental degradation and forest conservation must be part of a broader process of managing the landscape. Here to address this topic is the new Conservation Atlas of Tropical Forests: Africa, the first authoritative reference work on this subject. The second in a series this Conservation Atlas follows the format of the acclaimed Conservation Atlas of Tropical Forests: Asia and the Pacific (1991). Part I describes the issues, history of forests and climate, biological diversity, conservation of large mammals, and the peoples of the forests. Included are discussions of the links between population, environment and agriculture, the timber trade, protected areas system and the future for Africa's forests. Part II of the Atlas is a country by country survey of the forests of Africa. Stunning four-color maps, in a 9 x 12 format, have been compiled from satellite and radar imagery, aerial photography, and the latest information provided by forestry departments and development agencies. Both maps and text have been prepared and reviewed by a broad spectrum of specialists. The Atlas also includes four-color photographs and sketch maps. They represent the best visual portfolio available of Africa's forests today. For anyone interested in environmental issues, geography, forestry, development, economics, and the African region, this Atlas will be an essential resource.

Book excerpt: Generating Diversity deals with the enormous diversity of adaptations or organisms to common features of their environment, such as winter and the capture and processing of food. The generation of diversity is explained at a number of different levels, in particular illustrating how patterns of reproduction can alter genetic composition. An important theme is that energy and nutrients obtained by organisms can be put to a wide variety of uses, such as defence and growth. These uses are traded off against each other, helping to generate the extraordinary array of organisms on the planet.
