Elephants and Savanna Woodland Ecosystems by Christina Skarpe,Johan T. du Toit,Stein R. Moe Pdf

During the nineteenth century, ivory hunting caused a substantial decrease of elephant numbers in southern Africa. Soon after that, populations of many other large and medium-sized herbivores went into steep decline due to the rinderpest pandemic in the 1890s. These two events provided an opportunity for woodland establishment in areas previously intensively utilized by elephants and other herbivores. The return of elephants to currently protected areas of their former range has greatly influenced vegetation locally and the resulting potential negative effects on biodiversity are causing concern among stakeholders, managers, and scientists. This book focuses on the ecological effects of the increasing elephant population in northern Botswana, presenting the importance of the elephants for the heterogeneity of the system, and showing that elephant ecology involves much wider spatiotemporal scales than was previously thought. Drawing on the results of their research, the authors discuss elephant-caused effects on vegetation in nutrient-rich and nutrient-poor savannas, and the potential competition between elephants on the one hand and browsers and mixed feeders on the other. Ultimately this text provides a comprehensive review of ecological processes in African savannas, covering long-term ecosystem changes and human-wildlife conflicts. It summarises new knowledge on the ecology of the sub-humid African savanna ecosystems to advance the general functional understanding of savanna ecosystems across moisture and nutrient gradients.

The Living Elephants by Raman Sukumar Pdf

The Living Elephants is the authoritative resource for information on both Asian and African elephants. From the ancient origins of the proboscideans to the present-day crisis of the living elephants, this volume synthesizes the behavior, ecology and conservation of elephants, while covering also the history of human interactions with elephants, all within the theoretical framework of evolutionary biology. The book begins with a survey of the 60-million year evolutionary history of the proboscideans emphasizing the role of climate and vegetation change in giving rise to a bewildering array of species, but also discussing the possible role of humans in the late Pleistocene extinction of mastodonts and mammoths. The latest information on the molecular genetics of African and Asian elephants and its taxonomic implications are then presented. The rise of the elephant culture in Asia, and its early demise in Africa are traced along with an original interpretation of this unique animal-human relationship. The book then moves on to the social life of elephants as it relates to reproductive strategies of males and females, development of behavior in young, communication, ranging patterns, and societal organization. The foraging strategies of elephants, their impact on the vegetation and landscape are then discussed. The dynamics of elephant populations in relation to hunting for ivory and their population viability are described with the aid of mathematical models. A detailed account of elephant-human interactions includes a treatment of crop depredation by elephants in relation to their natural ecology, manslaughter by elephants, habitat manipulation by humans, and a history of the ivory trade and poaching in the two continents. The ecological information is brought together in the final chapter to formulate a set of pragmatic recommendations for the long-term conservation of elephants. The broadest treatment of the subject yet undertaken, by one of the leading workers in the field, Raman Sukumar, the book promises to bring the understanding of elephants to a new level. It should be of interest not only to biologists but also a broader audience including field ecologists, wildlife administrators, historians, conservationists and all those interested in elephants and their future.

East African Ecosystems and Their Conservation by T. R. McClanahan,T. P. Young Pdf

East Africa is one of the most diverse and interesting tropical area on the planet. It is home not only to the last great megafaunal assemblage, but also to human populations with the highest growth rates. This book draws on the expertise of leading ecologists, each intimately familiar with a particular set of East African ecosystems, to provide the first in-depth and integrated account of the ecology, management, threats, and conservation of these diverse ecosystems. Summarizing the tremendous wealth of scientific research that has come out of East Africa in the last few decades, each chapter analyzes a given ecosystem type, taking the reader through the basics of its ecology, its historical use (and misuse) by humans, and its prospects for conservation. Throughout the book, linkages and similarities among ecosystems are emphasized, the historical and contemporary role of humans in shaping these ecosystems is considered, fundamental principles of ecology are considered, and interesting case studies are highlighted. Students and researchers in ecology, conservation biology, and environmental sciences will find this book useful in their work.

Ecological Vulnerability by Katie Woolaston Pdf

Humans are responsible for biodiversity loss in many related and sometimes conflicting ways. Human-wildlife conflict, commonly defined as any negative interaction between people and wildlife, is a primary contributor to wildlife extinction and a manifestation of the destructive relationship that people have with wildlife. The author presents this 'wicked' problem in a social and legal context and demonstrates that legal institutions structurally deny human-wildlife conflict, while exacerbating conflict, promoting values consistent with individual autonomy, and ignoring the interconnected vulnerabilities shared by human and non-human species alike. It is the use of international and state law that sheds light on existing conflicts, including dingo conflict on K'Gari-Fraser Island in Australia, elephant conflict in Northern Botswana, and the global wildlife trade contributing to COVID-19. This book presents a critical analysis of human-wildlife conflict and its governance, to guide lawyers, scientists and conservations alike in the transformation of the management of human-wildlife conflict.

Arid Land Systems: Sciences and Societies by Troy Sternberg,Ariell Ahearn Pdf

Understanding deserts and drylands is essential, as arid landscapes cover >40% of the Earth and are home to two billion people. Today's problematic environment–human interaction needs contemporary knowledge to address dryland complexity. Physical dimensions in arid zones—land systems, climate and hazards, ecology—are linked with social processes that directly impact drylands, such as land management, livelihoods, and development. The challenges require integrated research that identifies systemic drivers across global arid regions. Measurement and monitoring, field investigation, remote sensing, and data analysis are effective tools to investigate natural dynamics. Equally, inquiry into how policy and practice affect landscape sustainability is key to mitigating detrimental activity in deserts. Relations between socio-economic forces and degradation, agro-pastoral rangeland use, drought and disaster and resource extraction reflect land interactions. Contemporary themes of food security, conflict, and conservation are interlinked in arid environments. This book unifies desert science, arid environments, and dryland development. The chapters identify land dynamics, address system risks and delineate human functions through original research in arid zones. Mixed methodologies highlight the vital links between social and environmental science in global deserts. The book engages with today's topical themes and presents novel analyses of arid land systems and societies.

The Biology of African Savannahs by Bryan Shorrocks,William Bates Pdf

Savannah habitats comprise an ecologically important, but ultimately fragile, ecosystem. They constitute one of the largest biomes on Earth, covering almost 20% of the land surface, and can be simply described as tropical and subtropical grasslands with scattered bushes and trees. Most savannahs occur in Africa, although smaller areas can be found in South America, India, and Australia. They form a rich mosaic of diverse ecosystems, and this book offers a concise but comprehensive introduction to their ecology, biodiversity, and conservation. The Biology of African Savannahs describes the major plants (grasses, and trees such as Acacia) and animals (mainly large mammals) that live in this habitat, and examines the biological and ecological factors that influence their population size, interactions (such as predation), and community composition. Conservation issues such as climate change, hunting, and conflict between wildlife and domestic animals are also discussed. This new edition has been updated throughout with the latest research in the field, and contains new technique boxes which introduce readers to some of the analytical methods used to study African savannahs. This accessible text is suitable for both senior undergraduate and graduate students taking courses in savannah and tropical ecology as part of a wider ecology and/or conservation biology degree programme. It will also be of relevance and use to the many professional ecologists and conservation practitioners requiring a concise but authoritative overview of the topic.
