The Biology and Conservation of Wild Felids (Hardcover, New): David Macdonald, Andrew Loveridge The Biology and Conservation of Wild Felids (Hardcover, New)
David Macdonald, Andrew Loveridge
R4,561 Discovery Miles 45 610 Ships in 10 - 15 working days

The editors utilize their 50 years of combined experience in professional engagement with the behaviour and ecology of wild felids to draw together a unique network of the world's most respected and knowledgeable experts. For the first time, this inter-disciplinary research programme is brought together within a single volume.
Beginning with a complete account of all 36 felid species, there follow 8 comprehensive review chapters that span all the topics most relevant to felid conservation science, including evolution and systematics, felid form and function, genetic applications, behavioural ecology, management of species that come into conflict with people and control of international trade in felid species, conservation tools/techniques, ex situ management, and felid diseases. 19 detailed case studies then delve deeply into syntheses of the very best species investigations worldwide, written by all the leading figures in the field. These chapters portray the unique attributes of the wild felids, describe their fascinating (and conflicting) relationship with humans, and create an unparalleled platform for future research and conservation measures. A final chapter analyses the requirements of, and inter-disciplinary approaches to, practical conservation with cutting-edge examples of conservation science and action that go far beyond the cat family.

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.

R2,032 Discovery Miles 20 320 Ships in 10 - 15 working days

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.

R2,078 Discovery Miles 20 780 Ships in 10 - 15 working days

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.

Emily Dickinson's poem "Split the Lark" refers to the "scarlet experiment" by which scientists destroy a bird in order to learn more about it. Indeed, humans have killed hundreds of millions of birds-for science, fashion, curiosity, and myriad other reasons. In the United States alone, seven species of birds are now extinct and another ninety-three are endangered. Conversely, the U.S. conservation movement has made bird-watching more popular than ever, saving countless bird populations; and while the history of actual physical human interaction with birds is complicated, our long aesthetic and scientific interest in them is undeniable. Since the beginning of the modern conservation movement in the mid-nineteenth century, human understanding of and interaction with birds has changed profoundly. In Scarlet Experiment, Jeff Karnicky traces the ways in which birds have historically been seen as beautiful creatures worthy of protection and study and yet subject to experiments-scientific, literary, and governmental-that have irrevocably altered their relationship with humans. This examination of the management of bird life in America from the nineteenth century to today, which focuses on six bird species, finds that renderings of birds by such authors as Henry David Thoreau, Emily Dickinson, Don DeLillo, and Christopher Cokinos, have also influenced public perceptions and actions. Scarlet Experiment speculates about the effects our decisions will have on the future of North American bird ecology.

R2,622 Discovery Miles 26 220 Ships in 10 - 15 working days

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.

Why has Canada been unable to achieve any of its climate-change targets? Part of the reason is that emissions in two provinces, Alberta and Saskatchewan - already about half the Canadian total when taken together - have been steadily increasing as a result of expanding oil and gas production. Declining emissions in other provinces, such as Ontario, Quebec, Nova Scotia, and New Brunswick, have been cancelled out by those western increases. The ultimate explanation for Canadian failure lies in the differing energy interests of the western and eastern provinces, overlaid on the confederation fault-line of western alienation. Climate, energy, and national unity form a toxic mix. How can Ottawa possibly get all the provinces moving in the same direction of decreasing emissions? To answer this question, Douglas Macdonald explores the five attempts to date to put in place coordinated national policy in the fields of energy and climate change - from Pierre Trudeau's ill-fated National Energy Program to Justin Trudeau's bitterly contested Pan-Canadian program - analysing and comparing them for the first time. Important new insights emerge from this analysis which, in turn, provide the basis for a new approach. Carbon Province, Hydro Province is a major contribution to the vital question of how our federal and provincial governments can effectively work together and thereby for the first time achieve a Canadian climate-change target.

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.

Jason M. Colby
R655 Discovery Miles 6 550 Ships in 10 - 15 working days

Orcas are the most profitable and controversial display animal in history, and since the release of the documentary Blackfish in 2013, millions around the world have focused on their plight. Yet no historical account has explored how we came to care about killer whales in the first place. In Orca, Jason Colby tells the exhilarating and often heartbreaking story of how people came to love the ocean's greatest predator. Historically reviled as dangerous pests, killer whales were dying by the hundreds, even thousands, by the 1950s-the victims of whalers, fishermen, and even the US military. In the Pacific Northwest, fishermen shot them, scientists harpooned them, and the Canadian government mounted a machine gun to eliminate them. But that all changed in 1965, when a Seattle entrepreneur named Ted Griffin became the first person to swim and perform with a captive killer whale. The show was a hit, and he began capturing and selling others, including Sea World's first "Shamu." Over the following decade, live display transformed popular and scientific views of Orcinus orca. The public embraced killer whales as charismatic and friendly while scientists enjoyed their first access to live orcas. In the Pacific Northwest, these captive encounters reshaped regional values and helped drive environmental activism, including Greenpeace's anti-whaling campaigns. Yet even as Northwesterners taught the world to love whales, they came to oppose their captivity. So when Sea World attempted to catch its own killer whales, Northwesterners would fight for the freedom of a marine predator that had become a regional icon. With access to previously unavailable documents and interviews, Colby offers the definitive history of how the feared and despised "killer" became the beloved "orca" and what that means for our relationship with the ocean and its creatures.

Forest Ecology and Conservation - A Handbook of Techniques (Paperback): Adrian Newton Forest Ecology and Conservation - A Handbook of Techniques (Paperback)
Adrian Newton
R2,214 Discovery Miles 22 140 Ships in 10 - 15 working days

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.

This is the first book to summarize the methods, conceptual issues and results of studies using the interpretation of feather growth rates as an index to nutritional condition in birds. The author has coined the term ptilochronology (literally. 'the study of feather time') to describe this technique, which relies on the fat that as a feather grows it produces visible growth bars. Both the technique and its conceptual foundations have been applied worldwide to numerous studies of avian evolution, ecology, and conservation biology. the author reviews this work, chronicles the various criticisms that have been amde, and describes how these have influenced the development of ptilochronology. He goes on to suggest experimental methodologies and analytical techniques to safeguard against invalid results. a final chapter summarises this new technique's contribution to avian biology, and suggests potential applications and a future research agenda. an appendix details specific measurements and describes the methodology associated with ptilochronology.
Ptilochronology provides a practical resource as well as a conceptual understanding of how this technique can be used to address important questions in avian biology. It will be of relevance and use to professional avian biologists and ornithologists as well as to graduate students of avian behavioural ecology, evolution and conservation.

The Biology of Temporary Waters (Paperback): D.Dudley Williams The Biology of Temporary Waters (Paperback)
D.Dudley Williams
R2,199 Discovery Miles 21 990 Ships in 10 - 15 working days

Temporary waters are found throughout the world, and include intermittent streams and ponds, episodic rain puddles, seasonal limestone lakes, the water-retaining structures of plants, such as bromeliads and pitcher plants, and a variety of man-made container habitats. They are probably populated by various plant, animal, and microscopic communities ranging from the very simple to the highly complex. Temporary waters therefore represent fascinating and significant arenas in which to study the properties of species, as the latter deal with the rigours of living in highly variable environments. Obligate temporary water species display a remarkable array of adaptations to the periodic loss of their primary medium that largely set them apart from the inhabitants of permanent water bodies. Survival of individuals frequently depends upon exceptional physiological tolerance or effective migrational abilities that are timed to appropriate habitat phases. Quite apart from their inherent biological interest, temporary waters are now in the limelight from a conservation perspective as these habitats come more and more into conflict with human activities. Traditionally, many temporary waters (be they ponds, pools, streams, or wetlands) have been considered to be 'wasted' areas of land, potentially convertible to agriculture once drained. In reality, they are natural features of the global landscape that represent distinct and unique habitats for many species, some that are found nowhere else and others that reach their maximum abundance and/or genetic diversity there. Temporary waters are also very important from a human health perspective since they function as breeding places for the vectors of many disease organisms, including those that spread malaria, schistosomiasis, yellow fever, and dengue. Most of these exact a high toll in terms of global human suffering and reduced regional economies. This book collates and synthesises the highly scattered and diverse global literature on pure and applied aspects of these habitats and their biota. It examines the ecology of temporary waters in both natural and human environments, and seeks to identify common evolutionary themes. It will be of particular interest to aquatic ecologists, invertebrate and vertebrate biologists, environmental biologists, wetland managers and conservationists, those charged with controlling water-associated diseases, entomologists, educators, and natural historians.

Herons and their close relatives, the egrets and bitterns, comprise sixty species in total and are found all over the world except in polar regions, and are a strikingly beautiful part of the wetlands they inhabit. They are particularly abundant and popular in South West USA, especially Florida. Herons are a diverse group, easily recognised by their long legs, necks and bills. Many species are notable for their sociality as they feed, roost, and nest together in single or mixed species assemblages. The authors have extensive experience of research and observation of these birds and this book provides an up to date comprehensive review of the herons of the world. Covering their biology, distribution, description, systematics, breeding, feeding, and conservation, James Hancock and James Kushlan have distilled their lifetimes' research on the heron into one volume. This volume is complemented by beautiful colour paintings especially painted for the book, colour photographs, and distribution maps.

Ragnhild Aslaug Sollund
R4,225 Discovery Miles 42 250 Ships in 10 - 15 working days

This book examines trade and trafficking in endangered animal species and how the trade increasingly puts large numbers of nonhuman species at risk. Focusing on illegal trafficking, the book also discusses the harmful aspects of the trade and trafficking which is taking place in concordance with laws and regulations. Drawing on the findings of empirical research from Norway and Colombia, the study discusses how this global, transnational trend is addressed, and features of the trade and the ways in which it is controlled in the two case study locations. It also explores the motives driving the trade, and the consequences in terms of animal abuse and environmental harm. The book discusses whether internationally agreed measures, such as international conventions, actually help prevent the trade. Possible ways to address the harms of wildlife trade are considered, including a total ban. The work draws on a green criminology and eco feminist theoretical framework to provide a broad perspective on concepts such as harm, animal rights, species justice and speciesism.

`Any fool can destroy trees. They cannot run away … God has cared for these trees … but he cannot save them from fools – only Uncle Sam can do that.’ First published in 1901, Our National Parks is possibly the bestselling book of Muir’s wilderness-discovery titles and was certainly the most influential published in his lifetime, with a strong focus on the preservation of forest reserves. With a strong political tone and shrewd, subtle manoeuvring, Muir uses Our National Parks to persuade his readership of the necessity of nature and national parks for human recreation and more importantly for health and wellbeing, as well as the – in his mind – obvious need for preservation of wild ecosystems. Cannily he counterbalances this with the acknowledgement of the need for timber and irrigation systems, in order that his message is taken seriously; Muir’s passion is portrayed so vividly and flamboyantly that without his learned political and scientific reinforcement, he could be misconstrued as purely a radical and eccentric nonconformist. However, the two combined result in an engaging and convincing argument that these landscapes are our `natural home’, and `fountains of life’. As Muir expert Terry Gifford observes in the foreword, `Muir’s tone can shift in this book from seductive persuasion, to charming details of creatures, flora and landscapes, to scientific information, to trail guide, to religious uplift, to a final political speech of startling ferocity.’ John Muir’s strategic yet genuine and beautiful conservationist essays were a first at the time of publication, and are still highly applicable to our attitudes and lifestyles today in the twenty-first century.

Grebes are unusual and unique in many ways: their habit of feather-eating; their method of sunbathing; their special method of underwater propulsion; the unusual structure of their feet; their courtship behaviour; and their floating nests. As the birds are dependent upon shallow wetlands, they are strongly affected and threatened by our use of their habitats, leading to dwindling populations and even extinction of some species. In this new addition to the Bird Families of the World series Jon Fjeldsa, a renowned expert on the grebes, provides an overview of the results of all the research that has been done on grebes. Part I contains a brief presentation of the grebe family, constraints of diving, the relationships between grebes and divers, and the morphology of grebes. Part II covers their biogeography, ecological distribution, feeding ecology, behaviour and communication, breeding biology, environmental threats, and conservation. Part III follows with 22 species accounts, including distribution maps. The plates section contains sixteen stunning paintings showing all the grebe species, by Jon Fjeldsa. The Grebes, like its companion volumes in the series, will be an indispensable work of reference for ornithologists, whether professional or amateur.
