Centring on South Africa's Hluhluwe-iMfolozi Park, this book synthesizes a century of insights from the ecology and conservation management of one of Africa's oldest protected wildlife areas. The park provides important lessons for conservation management, as it has maintained conservation values rivalling those of much larger parks sometimes through, and sometimes despite, strong management interventions, including the rescue of the white rhino from extinction. In addition, the book highlights the ecological science produced in the park, much of which has become widely influential, including the megaherbivore concept, new functional approaches to understanding biomes, and new understandings about the role of consumers in shaping ecosystems. The volume is ideal for researchers and policymakers interested in the conservation of relatively small, isolated and protected areas.

That humans originated from Africa is well-known. However, this is widely regarded as a chance outcome, dependant simply on where our common ancestor shared the land with where the great apes lived. This volume builds on from the 'Out of Africa' theory, and takes the view that it is only in Africa that the evolutionary transitions from a forest-inhabiting frugivore to savanna-dwelling meat-eater could have occurred. This book argues that the ecological circumstances that shaped these transitions are exclusive to Africa. It describes distinctive features of the ecology of Africa, with emphasis on savanna grasslands, and relates them to the evolutionary transitions linking early ape-men to modern humans. It shows how physical features of the continent, especially those derived from plate tectonics, set the foundations. This volume adequately conveys that we are here because of the distinctive features of the ecology of Africa.

This book provides students with the skills to develop their own models for application in conservation biology and wildlife management. Assuming no special mathematical expertise, the computational models used are kept simple and show how to develop models in both spreadsheet and programming language format. Develops thought-provoking applications which emphasize the value of modeling as a learning tool Examines basic descriptive equations, matrix representations, consumer-resources interactions, applications in simulation, scenarios, harvesting, population viability, metapopulation dynamics, disease outbreaks, vegetation stage and state dynamics, habitat suitability assessment, and model selection statistics Includes a wide range of examples relating to birds, fish, plants and large African mammals

This book aims to reconcile theoretical models of population dynamics with what is currently known about the population dynamics of large mammalian herbivores. It arose from a working group established at the National Center for Ecological Analysis and Synthesis at the University of California, Santa Barbara, to address the need for models that better accommodate environmental variability, especially for herbivores dependent on changing vegetation resources. The initial chapter reviews findings from definitive long-term studies of certain other ungulate populations, many based on individually identifiable animals. Other chapters cover climatic influences, emphasising temperate versus tropical contrasts, and demographic processes underlying population dynamics, more generally. There are new assessments of irruptive population dynamics, and of the consequences of landscape heterogeneity for herbivore populations. An initial review of candidate population models is followed up by a final chapter outlining how these models might be modified to better accommodate environmental variability. The contents provide a foundation for resolving problems of diminishing large mammal populations in Africa, over-abundant ungulate populations elsewhere, and general consequences of global change for biodiversity conservation. This book will serve as a definitive outline of what is currently known about the population dynamics of large herbivores.

Elephants are among the most magnificent – but also most problematic –members of South Africa's wildlife population. While they are sought after by South African and foreign tourists alike, they also have a major impact on their environment. As a result, elephant management has become a highly complex and often controversial discipline. The information needed to underpin vital decisions about elephant management has largely been unavailable to decision-makers, contested by experts, or simply unknown. As a result, the South African Minister for Environmental Affairs and Tourism convened a round table to advise him on this issue. The round table recommended that a scientific assessment of elephant management be undertaken to gather, evaluate, and present all the relevant information on this topic. Its main findings and recommendations are contained in this volume. Elephant Management is the first book of its kind, combining the work of more than 60 national and international experts. Extensively reviewed by policy-makers and other stakeholders, it is the most systematic and comprehensive review of savanna elephant populations and factors relevant to managing them to date. As such it is of interest to a broad spectrum of readers in South Africa and elsewhere. Above all, it is aimed at helping conservation policy-makers and practitioners to choose the best possible options for the sustainable preservation of these iconic animals.
