This book highlights classification patterns and underlying ecological drivers structuring the vegetation of selected indigenous subtropical forests in South Africa. It uses original field sampling and advanced numerical data analysis to examine three major types of forest – Albany Coastal Forests, Pondoland Coastal Scarp and Eastern Scarp – all of which are of high conservation value. Offering a unique and systematic assessment of South African ecology in unprecedented detail, the book could serve as a model for future vegetation surveys of forests not only in Africa, but also around the globe.
Come venture into the fascinating world of South Africae(tm)s natural heritage e" national parks and game reserves that rival any in Africa, scenic botanical gardens, and wildlife research programs.
Achievements and progress in genome mapping and the genomics of microbes supersede by far those for higher plants and animals, in part due to their enormous economic implication but also smaller genome size. In the post-genomic era, whole genome sequences of animal-associated microbes are providing clues to depicting the genetic basis of the complex host-pathogen relationships and the evolution of parasitism; and to improving methods of controlling pathogens. This volume focuses on a globally important group of intracellular prokaryotic pathogens which affect livestock animals. These include Brucella, Mycobacterium, Anaplasma and Ehrlichia, as well as the protozoan pathogens Cryptosporidium and Theileria, for which genome sequence data is available. Insights from comparative genomics of the microbes described provide clues to the adaptation involved in host-microbe interactions, as well as resources potentially useful for application in future research and product development.
This book engages with contemporary African human rights struggles including land, property, gender equality and legal identity. Through ethnographic field studies it situates claims-making by groups and individuals that have been subject to injustices and abuses, often due to different forms of displacement, in specific geographical, historical and political contexts. Exploring local communities’ complexities and divided interests it addresses the ambiguities and tensions surrounding the processes whereby human rights have been incorporated into legislation, social and economic programs, legal advocacy, land reform, and humanitarian assistance. It shows how existing relations of inequality, domination and control are affected by the opportunities offered by emerging law and governance structures as a plurality of non-state actors enter what previously was considered the sole regulatory domain of the nation state.
Small Carnivores: Evolution, Ecology, Behaviour, and Conservation This book focuses on the 232 species of the mammalian Order Carnivora with an average body mass 21.5 kg. Small carnivores inhabit virtually all of the Earth's ecosystems, adopting terrestrial, semi-fossorial, (semi-)arboreal or (semi-)aquatic lifestyles. They occupy multiple trophic levels and therefore play important roles in the regulation of ecosystems, such as natural pest control, seed dispersal and nutrient cycling. In areas where humans have extirpated large carnivores, small carnivores may become the dominant predators, which may increase their abundance ("mesopredator release") to the point that they can sometimes destabilize communities, drive local extirpations and reduce overall biodiversity. On the other hand, one third of the world's small carnivores are threatened or near threatened with extinction. This results from regionally burgeoning human populations' industrial and agricultural activities, causing habitat reduction, destruction, fragmentation and pollution. Overexploitation, persecution and the impacts of introduced predators, competitors, and pathogens have also negatively affected many small carnivore species. Although small carnivores have been intensively studied over the past decades, bibliometric studies showed that they have not received the same attention given to large carnivores. Furthermore, there is huge disparity in how research efforts on small carnivores have been distributed, with some species intensively studied and others superficially or not at all. This book aims at filling a gap in the scientific literature by elucidating the important roles of, and documenting the latest knowledge on, the world's small carnivores. p"This is a book that has been needed for decades. It is the first compendium of recent research on a group of mammals which has received almost no attention before the early 1970s. This book covers a wide range of subdisciplines and techniques and should be considered a solid baseline for further research on this little-known group of highly interesting mammals. As our knowledge regarding how ecosystems function increases, then the valuable role of small carnivores and the necessity for their conservation should be regarded as of paramount importance. The topics covered in this book should therefore be of great interest not only to academics and wildlife researchers, but also to the interested layman."
