This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Forests in the Eastern Arc Mountains are amongst the oldest and most biodiverse on Earth. They are a global priority for conservation and provide ecosystem services to millions of people. This thesis explores how spatial modelling can provide direction for conservation and botanical survey, and contribute to understanding of phytogeographical relationships. The ecoregion is rigorously defined by terrain complexity, vegetation distribution and established geoclimatic divisions, providing a coherent platform upon which to collate and monitor biological and socioeconomic information. Accordingly, 570 vascular plant taxa (species, subspecies and varieties) are found to be strictly endemic. The human population exceeds two million, with median density more than double the Tanzania average. Population pressure (accrued across the landscape) is shown to be greatest adjacent to the most floristically unique forests. Current knowledge on species distributions is subject to sampling bias, but could be systematically improved by iterative application of the bioclimatic models presented here, combined with targeted fieldwork. Tree data account for 80% of botanical records, but only 18% of endemic plant species; since conservation priorities differ by plant growth form, future fieldwork should aim to redress the balance. Concentrations of rare species correlate most strongly with moisture availability, whilst overall richness is better predicted by temperature gradients. Climate change impacts are projected to be highly variable, both across space and between species. Concordant with the theory that past climatic stability facilitated the accumulation of rare species, contemporary climates at sites of known endemic richness are least likely to be lost from dispersal-limiting mountain blocs during the 21st century. Faced with rapid population growth and the uncertainty of climate change, priorities for governance are to facilitate sustainable forest use and to maintain/restore habitat connectivity wherever possible. Overall, the thesis demonstrates that decision makers concerned with biodiversity conservation, particularly in mountain and coastal regions, should be wary of inferring local patterns of change from broad-scale models. The current study is a step toward spatially refined understanding of conservation priorities in the Eastern Arc Mountains, whilst novel methodologies have wider application in the fields of species distribution modelling and mountain analysis.

This book was released on 2013-04-17 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tanzania is one of the most biologically diverse nations in the world. Traveling from west to east across Tanzania, one encounters an incredible array of ecosystems and species. Beginning at Lakes Victoria, Tanganyika, and Nyasa that form much of the western boundary of Tanzania, one finds the most diverse and some of the most spectacular concentrations of endemic fish in any of the world's lakes. Moving further inland from the lakes, one meets the woodlands and plains of Serengeti, Ngorongoro, Tarangire, and Lake Manyara. The assemblages and movements of large mammals in these protected areas are unparalleled worldwide. Traveling yet further to the east, one comes to Mount Kilimanjaro, the highest mountain in Africa. Mount Kilimanjaro is of sufficient height to not only contain seven major vegetation zones, but also maintain permanent glaciers. Finally, shortly before arriving at the Indian Ocean, one encounters the Eastern Arc Mountains, a series of isolated and geologically ancient mountains, which due to their height and proximity to the Indian Ocean intercept sufficient precipitation to support, in many areas, moist tropical forest. The Eastern Arc Mountains are among the richest sites biologically in all of Africa and harbor unusually high concentrations of endemic species - species whose geographic distribution are restricted to these mountains. Unfortunately, much of Tanzania's biodiversity is threatened by habitat alteration, destruction, and exploitation. The Eastern Arc forests face some of the most severe threats to any of Tanzania's biologically unique sites.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an ambitious integration of ecological, archaeological, anthropological land use sciences, drawing on human geography, demography and economics of development across the East Africa region. It focuses on understanding and unpicking the interactions that have taken place between the natural and unnatural history of the East African region and trace this interaction from the evolutionary foundations of our species (c. 200,000 years ago), through the outwards and inwards human migrations, often associated with the adoption of subsistence strategies, new technologies and the arrival of new crops. The book will explore the impact of technological developments such as transitions to tool making, metallurgy, and the arrival of crops also involved an international dimension and waves of human migrations in and out of East Africa. Time will be presented with a widening focus that will frame the contemporary with a particular focus on the Anthropocene (last 500 years) to the present day. Many of the current challenges have their foundations in precolonial and colonial history and as such there will be a focus on how these have evolved and the impact on environmental and human landscapes. Moving into the Anthropocene era, there was increasing exposure to the International drivers of change, such as those associated with Ivory and slave trade. These international trade routes were tied into the ensuing decimation of elephant populations through to the exploitation of natural mineral resources have been sought after through to the present day. The book will provide a balanced perspective on the region, the people, and how the natural and unnatural histories have combined to create a dynamic region. These historical perspectives will be galvanized to outline the future changes and the challenges they will bring around such issues as sustainable development, space for wildlife and people, and the position of East Africa within a globalized world and how this is potentially going to evolve over the coming decades.

Available in PDF, EPUB and Kindle. Book excerpt: Mankind has evolved both genetically and culturally to become a most successful and dominant species. But we are now so numerous and our technology is so p- erful that we are having major effects on the planet, its environment, and the b- sphere. For some years prophets have warned of the possible detrimental consequences of our activities, such as pollution, deforestation, and overfishing, and recently it has become clear that we are even changing the atmosphere (e. g. ozone, carbon dioxide). This is worrying since the planet’s life systems are involved and dependent on its functioning. Current climate change – global w arming – is one recognised consequence of this larger problem. To face this major challenge, we will need the research and advice of many disciplines – Physics, Chemistry, Earth Sciences, Biology, and Sociology – and particularly the commitment of wise politicians such as US Senator Al Gore. An important aspect of this global problem that has been researched for several decades is the loss of species and the impoverishment of our ecosystems, and hence their ability to sustain themselves, and more particularly us! Through evolutionary time new species have been generated and some have gone extinct. Such extinction and regeneration are moulded by changes in the earth’s crust, atmosphere, and resultant climate. Some extinctions have been massive, particularly those asso- ated with catastrophic meteoric impacts like the end of the Cretaceous Period 65Mya.

Book excerpt: As part of a global effort to identify those areas where conservation measures are needed most urgently, World Wildlife Fund has assembled teams of scientists to conduct ecological assessments of all five continents. Terrestrial Ecoregions of Africa and Madagascar is the latest contribution, presenting in a single volume the first comprehensive assessment of biodiversity patterns, threats to biodiversity, and resulting conservation priorities across the African continent and its islands. Looking at biodiversity and threats in terms of biological units rather than political units, the book offers a comprehensive examination of African biodiversity across all biomes and multiple taxonomic groups. In addition to the seven main chapters, the book includes twenty essays by regional experts that provide more depth on key issues, as well as nine detailed appendixes that present summary data used in the analyses, specific analytical methodologies, and a thorough text description for each of Africa's 119 terrestrial ecoregions. Terrestrial Ecoregions of Africa and Madagascar provides a blueprint for conservation action and represents an unparalleled guide for investments and activities of conservation agencies and donor organizations.

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.
