Just like humans, animals and plants suffer from infectious diseases, which can critically threaten biodiversity. This book describes key studies that have driven our understanding of the ecology and evolution of wildlife diseases. Each chapter introduces the host and disease, and explains how that system has aided our general understanding of the evolution and spread of wildlife diseases, through the development and testing of important epidemiological and evolutionary theories. Questions addressed include: How do hosts and parasites co-evolve? What determines how fast a disease spreads through a population? How do co-infecting parasites interact? Why do hosts vary in parasite burden? Which factors determine parasite virulence and host resistance? How do parasites influence the spread of invasive species? How do we control infectious diseases in wildlife? This book will provide a valuable introduction to students new to the topic, and novel insights to researchers, professionals and policymakers working in the field.

Numbering 92 species worldwide, the order Lagomorpha is a focal point of conservation efforts. Approximately one-quarter of all lagomorphs are under conservation concern, and a few are quite literally on the brink of extinction. Here, leading conservation biologist Andrew T. Smith and his colleagues bring together the world's lagomorph experts in the most comprehensive reference on the order ever produced. With detailed species accounts-illustrated with stunning color photos and up-to-date range maps-contributors highlight key ecological roles that lagomorphs play and explain in depth how scientists around the globe are working to save vulnerable populations. Thematic introductory chapters cover a broad spectrum of information about pikas, rabbits, and hares, from evolution, systematics, and diseases to lagomorph conservation status and management. Each animal account begins with the complete scientific and common names for each species. A description of the appearance and unique morphological characteristics is accompanied by a range of standard measurements of adult specimens. Subsequent sections discuss known paleontological data concerning the species, the current state of its taxonomy and geographic variation, and various aspects of the animal's biology. Aimed at naturalists, professional biologists, and students, this book will also serve as a valuable reference for those conducting biodiversity surveys and conservation throughout the world.

R5,057 Discovery Miles 50 570 Ships in 10 - 15 working days

Despite the wealth of natural historical research conducted on migration over decades, there is still a dearth of hypothesis-driven studies that fully integrate theory and empirical analyses to understand the causes and consequences of migration, and a taxonomic bias towards birds in much migration research. This book takes a comparative, integrated view of animal migration, linking evolution with ecology and management, theory with empirical research, and embracing all the major migratory taxa (including human pastoralists). The scope extends beyond the target organism to consider the ecosystem-level dynamics of migration. The emphasis is on exciting new research avenues that are now opening up, whether due to advances in our understanding of migration as a biological phenomenon or through the availability of a range of new technologies.
Broad themes that emerge include integrating migration into the broad spectrum of movement behavior, the need for a comparative and cross-taxonomic approach that considers migration at a range of temporal and spatial scales, and examination of the key roles of resource uncertainty and spatial heterogeneity in driving migratory behavior. The book identifies the potential for new tools to revolutionize the study of migration, including satellite-tracking technology, genomics, and modeling - all of which are linked to increasing computing power. We are now on the verge of a breakthrough in migration research, which is crucial given the multiple threats that face the conservation of migration as a phenomenon, including climate change.

Emerging infectious diseases pose an increasingly serious threat to a number of endangered or sensitive species and are increasingly recognized as one of the major factors driving species extinction. Despite the significant impact of pathogens on conservation, no single book has yet integrated the theoretical principles underlying disease transmission with the practical health considerations for helping wildlife professionals and conservation biologists to manage disease outbreaks and conserve biodiversity. This novel and accessible book starts with a foundational section focusing on the role of pathogens in natural ecosystems, the dynamics of transmission in different environments, and the factors driving wildlife disease outbreaks. It then moves on to more applied issues concerned with the acquisition of field data including sampling, experimental design and analysis, as well as diagnostic analyses in both the laboratory and field. Guidelines for effective modelling and data analysis follow, before a final section is devoted to disease prevention and control including the prevention of novel outbreaks, the use of diseases as biocontrol agents, and the associated issues of ethics, public communication, and outreach. Infectious Disease Ecology and Conservation is primarily aimed at advanced undergraduates, graduate students, and established researchers in the fields of conservation biology, disease ecology, population ecology, and veterinary science. It will also be a valuable reference for conservation practitioners, land managers, and wildlife professionals who are required to deal with disease outbreak problems.

R5,554 Discovery Miles 55 540 Ships in 10 - 15 working days

This handbook is the most comprehensive and interdisciplinary work on marine conservation and fisheries management ever compiled. It is the first to bridge fisheries and marine conservation issues. Its innovative ideas, detailed case studies, and governance framework provide a global special perspective over time and treat problems in the high seas, community fisheries, industrial fishing, and the many interactions between use and non-use of the oceans. Its policy tools and ideas for overcoming the perennial problems of over fishing, habitat and biodiversity loss address the facts that many marine ecosystems are in decline and plagued by overexploitation due to unsustainable fishing practices. An outstanding feature of the book is the detailed case-studies on conservation practice and fisheries management from around the world. These case studies are combined with 'foundation' chapters that provide an overview of the state of the marine world and innovative and far reaching perspectives about how we can move forward to face present and future challenges.
The contributors include the world's leading fisheries scientists, economists, and managers. Ecosystem and incentive-based approaches are described and complemented by tools for cooperative, participatory solutions. Unique themes treated: fisher behavior and incentives for management beyond rights-based approaches; a synthesis of proposed 'solutions'; a framework for understanding and overcoming the critical determinants of the decline in fisheries, degradation of marine ecosystems, and poor socio-economic performance of many fishing communities; models for innovative policy instruments; a plan of action and adoption pathways to promote sustainable fishing practices globally.
Collectively, the handbook's many valuable contributions offer a way forward to both understanding and resolving the multifaceted problems facing the world's oceans.

R2,301 Discovery Miles 23 010 Ships in 10 - 15 working days

Rain forests represent the world's richest repository of terrestrial biodiversity, and play a major role in regulating the global climate. They support the livelihoods of a substantial proportion of the world's population and are the source of many internationally traded commodities. They remain (despite decades of conservation attention) increasingly vulnerable to degradation and clearance, with profound though often uncertain future costs to global society. Understanding the ecology of these diverse biomes, and peoples' dependencies on them, is fundamental to their future management and conservation.
Tropical Rain Forest Ecology, Diversity, and Conservation introduces and explores what rain forests are, how they arose, what they contain, how they function, and how humans use and impact them. The book starts by introducing the variety of rain forest plants, fungi, microorganisms, and animals, emphasising the spectacular diversity that is the motivation for their conservation. The central chapters describe the origins of rain forest communities, the variety of rain forest formations, and their ecology and dynamics. The challenge of explaining the species richness of rain forest communities lies at the heart of ecological theory, and forms a common theme throughout. The book's final section considers historical and current interactions of humans and rain forests. It explores biodiversity conservation as well as livelihood security for the many communities that are dependent on rain forests - inextricable issues that represent urgent priorities for scientists, conservationists, and policy makers.

R2,396 Discovery Miles 23 960 Ships in 10 - 15 working days

It is becoming clear that the Mediterranean region is one of the "hottest" of the biodiversity hotspots on the planet. There is also an increasing concern for the conservation, adaptive management, and restoration of the unique natural ecosystems and cultural landscapes that characterize this area. The region's biological and cultural heritage as well as its huge wealth of biodiversity is now at real risk. This brings a further urgency to the task of communicating detailed but readily accessible information on the Mediterranean biota, and an ecological, historical and evolutionary perspective to the changing contexts in which the region's flora and fauna continue to evolve.
There is no other recent textbook devoted solely to Mediterranean evolutionary ecology, and a synthesis of the many recent advances is now overdue. This new work builds on the success and reputation of the first edition, although the text has been updated and expanded to document recent changes to biodiversity, new ecological and evolutionary insights, and the challenges for the future. These changes include the addition of two new chapters devoted to the Mediterranean Sea itself, and especially the coastal areas. Throughout the book, the pressing issues of global change (especially climate warming) are addressed, in conjunction with changing land use, and in terms of their potential impact on biota, communities, ecosystems, and landscapes.

Bioinvasions and Globalization synthesises our current knowledge of the ecology and economics of biological invasions, providing an in-depth evaluation of the science and its implications for managing the causes and consequences of one of the most pressing environmental issues facing humanity today.
Emergent zoonotic diseases such as HIV and SARS have already imposed major costs in terms of human health, whilst plant and animal pathogens have had similar effects on agriculture, forestry, fisheries. The introduction of pests, predators and competitors into many ecosystems has disrupted the benefits they provide to people, in many cases leading to the extirpation or even extinction of native species. This timely book analyzes the main drivers of bioinvasions - the growth of world trade, global transport and travel, habitat conversion and land use intensification, and climate change - and their consequences for ecosystem functioning. It shows how bioinvasions impose disproportionately high costs on countries where a large proportion of people depend heavily on the exploitation of natural resources. It considers the options for improving assessment and management of invasive species risks, and especially for achieving the international cooperation needed to address bioinvasions as a negative externality of international trade.

This practical manual of amphibian ecology and conservation brings together a distinguished, international group of amphibian researchers to provide a state-of-the-art review of the many new and exciting techniques used to study amphibians and to track their conservation status and population trends. The integration of ecology and conservation is a natural outcome of the types of questions posed by these disciplines: how amphibians can and should be sampled, marked, and followed through time; how abundance and population trends are measured; what are the robust statistical methods that can be used in ecology and conservation; what roles do amphibians play in community structure and function; how do animals function in their environment; and what affects the long-term persistence of species assemblages?
Although emphasizing field ecology, sections on physiological ecology, genetics, landscape ecology, and disease analysis are also included. The book describes the latest statistical approaches in amphibian field ecology and conservation, as well as the use of models in interpreting field research. Much of this information is scattered in the scientific literature or not readily available, and the intention is to provide an affordable, comprehensive synthesis for use by graduate students, researchers, and practising conservationists worldwide.

Biological invaders represent one of the primary threats to the maintenance of global biodiversity, human health, and the success of human economic enterprises. The continuing globalization of our society ensures that the need to understand the process of biological invasion will only increase in the future. There is also a growing recognition that the study of biological invaders provides a unique insight into basic questions in ecology and evolution.
The study of exotic birds has had a particularly long history and has come to represent a fascinating intersection between the study of biological invasions, avian conservation biology, and basic principles of ecology and evolution. Avian Invasions summarizes and synthesizes this unique historical record and unravels the insights that the study of exotic birds brings to all three of these research strands. It includes chapters on the well-known contributions of exotic bird study to ecological science, and on the post-establishment evolution of introduced bird populations. The result is the most comprehensive picture yet of the invasion process.
Avian Invasions is aimed at professional avian biologists and ornithologists as well as graduate students of avian ecology, evolution and conservation. It also appeals to a more general audience of invasion ecologists.

The purpose of this book is to review and analyze the period (roughly from the 1950s to the present) when the environment became an issue as important as economic growth, or war and peace; to assess the current situation, and begin planning for the challenges that lie ahead. Most people are aware of both the environmental destruction taking place around the world and of the specter of climate change. The devastation of New Orleans by hurricane Katrina illustrates the potential for disaster when climate change is combined with the mismanaged environmental policy. How did we get tot his point? What has been done and what can be done to avoid future environmental disasters? Thirty-two contributing chapter authors (among them, one of the principal drafters of the National Environmental Policy Act, Chief of the African Environment Division and the World Bank, Vice President of the Center for Conservation Innovation at the World Wildlife Fund, President of the Zoological Society of London, former President of the Ecological Society of America) use their unique, authoritative perspective to review the evolution of environmental science and policy in the past half century. Each author describes the evolution of environmental science and policy in the past half century and consider the challenges of the future. Although the authors of this book com from various fields, they have followed paths that have generally converged on the concept of sustainability. This book attempts to define what sustainability is, how we can achieve it, and what the prospects for sustainability in the future are.

This advanced text focuses on the uses of distance sampling to estimate the density and abundance of biological populations. It addresses new methodologies, new technologies and recent developments in statistical theory and is the follow up companion to Introduction to Distance Sampling (OUP, 2001).
In this text, a general theoretical basis is established for methods of estimating animal abundance from sightings surveys, and a wide range of approaches to analysis of sightings data is explored. These approaches include: modelling animal detectability as a function of covariates, where the effects of habitat, observer, weather, etc. on detectability can be assessed; estimating animal density as a function of location, allowing for example animal density to be related to habitat and other locational covariates; estimating change over time in populations, a necessary aspect of any monitoring program; estimation when detection of animals on the line or at the point is uncertain, as often occurs for marine populations, or when the survey region has dense cover; survey design and automated design algorithms, allowing rapid generation of sound survey designs using geographic information systems; adaptive distance sampling methods, which concentrate survey effort in areas of high animal density; passive distance sampling methods, which extend the application of distance sampling to species that cannot be readily detected in sightings surveys, but can be trapped; and testing of methods by simulation, so that performance of the approach in varying circumstances can be assessed.

"Very few people have spent as much time as William E. Glassley in such deep wilderness. So it would behoove us to pay attention even if he had not brought back such a fascinating, lovely, and useful set of observations. This is a remarkable book." Bill McKibben, author of The End of Nature and Oil and Honey "The profound mystery of our living Earth saturates this memorable book." John Elder, coeditor of The Norton Book of Nature Writing and author of Picking Up the Flute Greenland, one of the last truly wild places, contains a treasure trove of information on Earth's early history embedded in its pristine landscape. Over numerous seasons, William E. Glassley and two fellow geologists traveled there to collect samples and observe rock formations for evidence to prove a contested theory that plate tectonics, the movement of Earth's crust over its molten core, is a much more ancient process than some believed. As their research drove the scientists ever farther into regions barely explored by humans for millennia if ever Glassley encountered wondrous creatures and natural phenomena that gave him unexpected insight into the origins of myth, the virtues and boundaries of science, and the importance of seeking the wilderness within. An invitation to experience a breathtaking place and the fascinating science behind its creation, A Wilder Time is nature writing at its best. William E. Glassley is a geologist at the University of California, Davis, and an emeritus researcher at Aarhus University, Denmark, focusing on the evolution of continents and the processes that energize them. He lives in Santa Fe, New Mexico.

Published to coincide with the Global Summit on illegal wildlife trade to be hosted by David Cameron in London in February 2014, Trading to Extinction is a unique and devastating record of this tragic industry. The book explores the sad truths behind this multi billion-dollar industry and is one of the most comprehensive photographic documents on the wildlife trade, spanning more than 10 years and offering a rare view into this illicit business. It is a shocking tale of cruelty, crime and human greed. This is an industry which, like the drugs trade, is fuelled by money, and whose tentacles encircle the world, from the remote forests of Asia to the trafficking hubs of Beijing, Bangkok, London, Tokyo and New York. A poacher who kills a rhino and removes its horn in India gets $350. That same horn sells for $1,000 in a nearby market town. By the time it reaches Hong Kong, Beijing or the Middle East, the horn is worth $60,000 per kilogram, rivalling the street value of cocaine, and even the price of gold. Tiger bones are worth up to $700 per kilo. Meanwhile the price of ivory is increasing so rapidly that some people are buying it as an investment commodity. The numbers are truly staggering. Trading to Extinction combines the powerful black and white photographs of Patrick Brown with texts by Ben Davies, who has spent more than a decade investigating the black market trade in wildlife. He takes the reader on a first hand journey into the seedy world of the illegal animal trade and its gruesome pursuit of profit, as well as describing international efforts to stop it. Both Patrick Brown and Ben Davies are recognised experts in the subject and their insight and knowledge provides a staggering overview of this hideous industry.

Forest conservation has become one of the most important environmental issues currently facing humanity, as a result of widespread deforestation and forest degradation. Pressures on remaining natural forests continue to intensify, leading to high rates of biodiversity loss. Understanding how human activities influence ecological processes within forests is essential for developing effective conservation action.
This book describes research methods and techniques relevant to understanding forest ecology, with a particular focus on those that are relevant to practical conservation and sustainable forest management. This information is currently disparate and difficult to locate and, as with other books in this series, the intention is to provide a comprehensive synthesis for use by graduate students, researchers and practising conservationists. Methods are presented for assessing forest extent and condition, structure and composition, and forest dynamics at a variety of scales. Techniques for assessing genetic variation and reproductive ecology, and for evaluating the habitat value of forests are also described. Particular emphasis is given to state-of-the-art techniques such as remote sensing, GIS, computer modelling and molecular markers. However, traditional methods of forest mensuration and ecological survey are also presented. The methods and techniques described are generally applicable to all forest types, including both temperate and tropical forest ecosystems.
