Conservation Biology in Sub-Saharan Africa comprehensively explores the challenges and potential solutions to key conservation issues in Sub-Saharan Africa. Easy to read, this lucid and accessible textbook includes fifteen chapters that cover a full range of conservation topics, including threats to biodiversity, environmental laws, and protected areas management, as well as related topics such as sustainability, poverty, and human-wildlife conflict. This rich resource also includes a background discussion of what conservation biology is, a wide range of theoretical approaches to the subject, and concrete examples of conservation practice in specific African contexts. Strategies are outlined to protect biodiversity whilst promoting economic development in the region. Boxes covering specific themes written by scientists who live and work throughout the region are included in each chapter, together with recommended readings and suggested discussion topics. Each chapter also includes an extensive bibliography. Conservation Biology in Sub-Saharan Africa provides the most up-to-date study in the field. It is an essential resource, available on-line without charge, for undergraduate and graduate students, as well as a handy guide for professionals working to stop the rapid loss of biodiversity in Sub-Saharan Africa and elsewhere.
This practical manual of freshwater ecology and conservation provides a state-of-the-art review of the approaches and techniques used to measure, monitor, and conserve freshwater ecosystems. It offers a single, comprehensive, and accessible synthesis of the vast amount of literature for freshwater ecology and conservation that is currently dispersed in manuals, toolkits, journals, handbooks, 'grey' literature, and websites. Successful conservation outcomes are ultimately built on a sound ecological framework in which every species must be assessed and understood at the individual, community, catchment and landscape level of interaction. For example, freshwater ecologists need to understand hydrochemical storages and fluxes, the physical systems influencing freshwaters at the catchment and landscape scale, and the spatial and temporal processes that maintain species assemblages and their dynamics. A thorough understanding of all these varied processes, and the techniques for studying them, is essential for the effective conservation and management of freshwater ecosystems.
It now seems incontrovertible (as Alessandra Giannini has demonstrated) that the series of Sahelian droughts that began in the early 1970s were driven by changes in sea surface temperatures and that they were not caused by local land use mismanagement in the Sahel itself. Combined with the apparent re-greening of the Sahel, these findings effectively close a long-standing policy and scientific debate (in which the lead authors of this book participated) on the causes and extent of desertification in the Sahel. The opportunity now presents itself to treat this debate as a historical object lesson in the relationship between science, the formation of public opinion, and international policy-making in the context of climate change. In short, what might the ‘great Sahelian desertification boondoggle’ have to tell us about current attempts to come to grips with climate change?
Gain state-of-the-art knowledge of new research and developments in transgenic technology! Genetically Modified Crops: Their Development, Uses, and Risks provides groundbreaking information on the integration of foreign DNA into the nucleus of a plant cell to produce a positive transformation. This volume details methods of gene delivery, laboratory tools and techniques to increase success rates, and the benefits, risks, and limitations of these methods. Authors at the forefront of this developing technology provide a comprehensive overview of transgenic crops and vital research on specific plant genera that have undergone transgenic transformation. Agricultural biotechnology has become a national and necessary mainstay of farming and food production, and this book is an important scientific tool to keep you informed of the latest protocols of genetic transformation. This book also outlines the goals that scientists are striving to reach, such as targeted gene expression where the gene only expresses itself at a certain time in the plant’s life cycle, but disappears before human consumption. One of the greatest concerns is maintaining the welfare of the consumer, and in this volume the authors repeatedly discuss their findings in terms of safety for human consumption. With Genetically Modified Crops: Their Development, Uses, and Risks, you’ll explore: the history of crop transformation and the techniques most commonly used for gene delivery, including biolistic bombardment and Agrobacterium-mediated transformation various methods of determining successful gene transfer in putative transgenic plants, such as blotting, functional assaying, and progeny testing the utilization of recombinase-directed plant transformation to improve faithful and consistent gene delivery and transference the successful reproduction of an insecticidal protein from chicken eggs in transgenic corn—and its benefits to society the current status of risk assessment and examples of incidents that have raised the level of concern about genetically modified plants outside the lab This book also contains several chapters about current methods of transformation involving specific crops such as: cotton wheat alfalfa sorghum rice and more! Genetically Modified Crops: Their Development, Uses, and Risks is an indispensable guidebook for agronomists, plant and molecular geneticists, and students in agronomy, genetics, entomology, horticulture, and plant pathology. This manual is also useful to concerned consumers who wish to know the latest scientific findings on genetically modified crops. Complete with references, figures, and photographs, this book is a must-read to keep up to date with science and technology.
An increasing variety of biological problems involving resource management, conservation and environmental quality have been dealt with using the principles of population biology (defined to include population dynamics, genetics and certain aspects of community ecology). There appears to be a mixed record of successes and failures and almost no critical synthesis or reviews that have attempted to discuss the reasons and ways in which population biology, with its remarkable theoretical as well as experimental advances, could find more useful application in agriculture, forestry, fishery, medicine and resource and environmental management. This book provides examples of state-of-the-art applications by a distinguished group of researchers in several fields. The diversity of topics richly illustrates the scientific and economic breadth of their discussions as well as epistemological and comparative analyses by the authors and editors. Several principles and common themes are emphasized and both strengths and potential sources of uncertainty in applications are discussed. This volume will hopefully stimulate new interdisciplinary avenues of problem-solving research.
A guide to the freshwater fish of the Southern African subregion. Species descriptions include: a colour painting; symbols indicating uses and conservation status as well as a description of the fish, its habits and habitat. Keys to families, genera and species aid identification.
