Originally published in 1979, Wildlife Management in Savannah Woodland provides a multidisciplinary approach to the environment. Developed by local scientists with a deep knowledge and understanding of the local situation, the book provides a pragmatic and realistic approach to West African conditions.

The Kruger National Park is one of the world’s leading stewards of biological diversity. Its management requires ongoing monitoring and re-evaulation to ensure that species survive.

Shaping Kruger provides fascinating insight into the lives, habits and behaviour of the larger animals that significantly affect the workings of the park. It expertly synthesizes decades of ground-breaking research into the animals and their environment, examining along the way individual species; predator-prey relationships; mammal distribution, and browsing and grazing interactions.

This detailed look at how Park management has had to interpret, monitor and adapt the processes that allow species to survive – even thrive – in an ever-changing environment makes for an intriguing and enlightening read.

Britain was a very different place 15,000 years ago - home to lions, lynx, bears, wolves, bison and many more megafauna. But as its climate changed and human populations expanded, most of early Britain's largest mammals disappeared. Will advances in science and technology mean that we can one day bring these mammals back? And should we? In The Missing Lynx, palaeontologist Ross Barnett uses case studies, new fossil discoveries and biomolecular evidence to paint a picture of these lost species and to explore the ecological significance of their disappearance. He discusses how the Britons these animals shared their lives with might have viewed them and investigates why some species survived while others vanished. Barnett also looks in detail at the realistic potential of reintroductions, rewilding and even of resurrection in Britain and overseas, from the successful return of beavers in Argyll to the revolutionary Pleistocene Park in Siberia, which has already seen progress in the revival of 'mammoth steppe' grassland. As widespread habitat destruction, climate change and an ever-growing human population lead us inexorably towards the sixth extinction, this timely book explores the spaces that extinction has left unfilled. And by helping us to understand why some of our most charismatic animals are gone, Ross Barnett encourages us to look to a brighter future, one that might see these missing beasts returned to the land on which they once lived and died.

Biostatistics with R provides a straightforward introduction on how to analyse data from the wide field of biological research, including nature protection and global change monitoring. The book is centred around traditional statistical approaches, focusing on those prevailing in research publications. The authors cover t-tests, ANOVA and regression models, but also the advanced methods of generalised linear models and classification and regression trees. Chapters usually start with several useful case examples, describing the structure of typical datasets and proposing research-related questions. All chapters are supplemented by example datasets, step-by-step R code demonstrating analytical procedures and interpretation of results. The authors also provide examples of how to appropriately describe statistical procedures and results of analyses in research papers. This accessible textbook will serve a broad audience, from students, researchers or professionals looking to improve their everyday statistical practice, to lecturers of introductory undergraduate courses. Additional resources are provided on www.cambridge.org/biostatistics.

This book encompasses the body of available scientific information on the notothenioid fish Pleuragramma antarctica commonly known as Antarctic silverfish. This plankton-feeder of the intermediate trophic level is the most abundant fish in the coastal regions of high Antarctica, and plays a pivotal ecological role as the main prey of top predators like seals, penguins, whales and Antarctic toothfish. Broad circum-polar distribution, a key role in the Antarctic shelf pelagic ecosystem, and adaptations makes understanding the species' likely response to environmental change relevant to foresee the potential responses at the local ecosystem level. Additionally, a detailed understanding of the abundance and trophic interactions of such a dominant keystone species is a vital element of informing the development of marine spatial planning and marine protected areas in the Antarctic continental shelf region. Experts in the field provide here unique insights into the evolutionary adaptation, eco-physiology, trophic ecology, reproductive and population ecology of the Antarctic silverfish and provide new clues about its vulnerability in facing the challenges of the ongoing environmental changes.

This book explores how the state can foster collective action by fisher's communities in fisheries management. It presents a different perspective from Elinor Ostrom's classic work on the eight institutional conditions that foster collective action in natural resource management and instead emphasizes the role of the state in fisheries co-management, engaging a state-centric notion of 'meta-governance'. It argues that first, the state is required to foster collective action by fishers; and secondly, that the current fisheries co-management arrangements are state-centric. The study develops these arguments through the analysis of three case studies in Japan, Vietnam and Norway. The author also makes a theoretical contribution to governance literature by developing Ostrom's 'society-centric' framework in a way which makes it more amenable to the analysis of state capacity and government intervention in a comparative context. This book will appeal to students and scholars of global governance, fisheries management, co-management, and crisis management, as well as practitioners of fisheries management.

This book provides a snapshot of representative modeling analyses of coastal hypoxia and its effects. Hypoxia refers to conditions in the water column where dissolved oxygen falls below levels that can support most metazoan marine life (i.e., 2 mg O2 l-1). The number of hypoxic zones has been increasing at an exponential rate since the 1960s; there are currently more than 600 documented hypoxic zones in the estuarine and coastal waters worldwide. Hypoxia develops as a synergistic product of many physical and biological factors that affect the balance of dissolved oxygen in seawater, including temperature, solar radiation, wind, freshwater discharge, nutrient supply, and the production and decay of organic matter. A number of modeling approaches have been increasingly used in hypoxia research, along with the more traditional observational and experimental studies. Modeling is necessary because of rapidly changing coastal circulation and stratification patterns that affect hypoxia, the large spatial extent over which hypoxia develops, and limitations on our capabilities to directly measure hypoxia over large spatial and temporal scales. This book consists of 15 chapters that are broadly organized around three main topics: (1) Modeling of the physical controls on hypoxia, (2) Modeling of biogeochemical controls and feedbacks, and, (3) Modeling of the ecological effects of hypoxia. The final chapter is a synthesis chapter that draws generalities from the earlier chapters, highlights strengths and weaknesses of the current state-of-the-art modeling, and offers recommendations on future directions.

The aim of this book is to systematize and discuss population genetic studies of freshwater fish in a region that harbors the greatest diversity of species among all inland water ecosystems. This volume explores the genetic evaluation for a number of orders, families and species of Neotropical fishes, and provides an overview on genetic resources and diversity and their relationships with fish domestication, breeding, and food production.

Protecting Endangered Species in the United States is a collection of original papers by economists, biologists and political scientists with a common theme--protecting species at risk while safeguarding social order is a policy challenge that entangles biology, politics, and economics. The volume begins by assessing the biological needs that define the endangered species problem. The authors then explore the political realities that delimit the debate--who pays the costs and receives the benefits, and how interest groups affect species protection. The book addresses the economic choices that must be confronted for effective protection strategies including incentive schemes to promote preservation on public and private land.

This book documents and examines the state of health of coral reefs in the eastern tropical Pacific region. It touches on the occurrence of coral reefs in the waters of surrounding countries, and it explores their biogeography, biodiversity and condition relative to the El Nino southern oscillation and human impacts. Additionally contained within is a field that presents information on many of the species presented in the preceding chapters.

Many endangered species of wild animals are managed in captivity through studbooks. In this book these data-rich resources are mined in innovative, integrated and statistically tested ways to maximise information gain for conservation practice - whether for captive or released/reintroduced or managed wild populations. This book is thus an important tool for all species managers, and for students and researchers in small population biology and wildlife conservation. The book's studbook analyses are grouped in three interrelated sections: natural history, demography and genetics. Statistical tests to determine the significance of results or to compare results between subgroups are undertaken throughout. Real studbooks of a variety of species, e.g. cranes, wolverines, blesbok, illustrate the practical applications and interpretations of the analyses and statistics. The "natural history" section presents analyses to determine baseline species information such as litter size, inter-birth interval, longevity and seasonality. "Demography" covers census(-style) analyses, age-class based life tables, comparative survival analyses and population projections. Solutions for dealing with small sample sizes are included.Inbreeding depression and unconscious selection form the main focus of the "genetics" section. Survival and life table analyses are used to assess inbreeding effects. Quantitative genetics methods are applied to natural history traits as a tool to monitor genetic variation. A fourth section on "conservation" shows how data from captive populations can be used where natural history data from wild populations are missing. A real example uses studbook data to inform Population Viability Analysis. The final section deals with issues related to incomplete and missing data and statistical topics. The purpose-written open-source software programs "Population Management Library (PML)" and "studbookR" used for analyses in the book, are available at www.princee.com.

Rare British Breeds is a book inspired by the Rare Breed Survival Trust Watchlist, which is published annually, listing the species of sheep, cattle, horses, pigs, goats and poultry (chickens, turkeys, ducks and geese) that are endangered in the United Kingdom. This information is gathered from breed societies and lists the number of breeding females alive, along with their conservation status. Each species, regardless of their origin, is unique to the UK, either through cross breeding or by evolution. There are good reasons for wanting to keep these breeds alive; not just the genetic makeup of these creatures which means many are able to survive and thrive in very formidable conditions - a prerequisite for enduring possible future environmental disasters. Once gone, these genes will never be able to be replaced. They have taken thousands of years to develop. The book looks at the history of every breed, with their evolutionary roots, development over time, exportation, cross breeding and changing relationship to mankind as farming techniques react to societal shifts. Their particular physical characteristics such as meat, wool, milk, eggs or ability to pull great weights are discussed as well as their conservation status and the national and international efforts being made to ensure their survival.

This Brief discusses potential alternative sources for feeds in aquaculture fish diet, and explains that the future of aquaculture's development is dependent on the costs of fishmeal and fish oil. Considering that the increasing costs of traditional feeds constrain this development, research is looking into alternatives, which can ensure adequate nutrition for animals' growth. This work reviews the use of alternative plant, microbial and insect protein sources, evaluating in particular their impact on growth, nutrient digestibility, fillet quality traits and sensorial perception in the most important farmed marine and freshwater fish species. The Brief specifically summarizes the pros and cons of plant oils from oilseeds, which can on the one hand be a sustainable substitute for fish oil, but which are on the other hand less rich in omega-3 long-chain polyunsaturated fatty acids. The feeding might therefore result in an undesired reduced nutritional value of the flesh of farmed fish. The authors also explore the possible use of fishery discards as potential aquaculture feed source. Since the landing of by-catch will with the new Common Fisheries Policy (CFP) become obligatory (instead of simply returning it to the sea, often dead), suitable uses of what must not be used for human consumption can be investigated. The authors give an outlook whether this might become a sensible alternative to improve the management of discards and create more sustainable fisheries. The Brief also addresses the issues of additives to aquafeeds, such as vitamins, minerals, and antioxidants, but also immunostimulants and enzymes. The authors discuss which effects these additives may have on fish growth, welfare, reproduction and health status in aquacultures.

Bat detector surveys are carried out by ecological consultants, researchers, conservationists and hobbyists. Understanding and categorising non-bat sounds in surveys offers the potential of knock-on benefits for informing development projects (e.g. other important records discovered within a site), as well as the possibility of associated conservation benefits. In recent years the number of people carrying out these surveys and recording calls with bat detectors has grown considerably. These surveys often generate vast amounts of audio recordings, resulting in the heavy workload associated with completing the sound analysis and reporting process. Those carrying out analysis can be distracted, intrigued or delayed owing to the occurrence of recordings that are unfamiliar and not identifiable to them. These recordings can relate to 'difficult to ID' bat species, but also, often, sounds not related to bats. This can be especially true when noise triggers such as insects, small mammals or birds look like bat-related noise. Therefore, only knowing what bats sound like is not enough. It is extremely useful to know what other sources of noise look and sound like within the same soundscape. This resource will help bat workers, in whatever environment they are in, to be more confident in recognising, categorising and dismissing other sounds. The book includes a substantial downloadable sound library (.wav format) that readers can listen to by ear or process through sound analysis software. Is That a Bat? also caters for sounds that are also heard by ear alone, in the field, during the hours of darkness. These scenarios often have bat surveyors intrigued or confused as to what they are listening to. Occasionally, knowing what these sounds are could be important, or at the very least, of interest. The first chapter caters for the subject overall, including suggestions from the author as to why the subject matter is of value. It also discusses bat-related calls (including social calls) with a view to offering comparisons against the other sources of sound discussed in separate chapters. Continuing through the book, there are chapters covering the following: small mammals; amphibians; insects; birds; electrical/mechanical noise; and other noise/nuisances. Within each chapter there are sub-sections about bat detector recorded sound, sound by ear, as well as advice on techniques and methods to reduce or increase the likelihood of recording other sounds. The book concludes with associated appendices, including a 'Problem Solving Key' to help those encountering an unfamiliar sound to narrow it down to the likely source. With technology advancing at pace, the technical ability of the analyst is of huge importance. With a wider perspective and more knowledge, those responsible for interpreting field encounters can be more confident when making decisions about sources of sound. Apart from that, 'knowing stuff' makes the job far more interesting and gives the bat worker a greater appreciation of the natural world within which they are working.

'When a man plants a tree, he plants himself. Every root is an anchor, over which he rests with grateful interest, and becomes sufficiently calm to feel the joy of living.' Steep Trails encompasses a delightful mix of John Muir's essays and adventure narratives, spanning a period of twenty-nine years. The selections included in this book are varied: ranging from geological studies to stories of the people and towns he encounters throughout his exploits. As Muir expert Terry Gifford observes in the foreword, 'Most of Steep Trails' chapters are dispatches from Muir as travelling correspondent with a mixture of insights into local cultures, criticism of pollution and enthusiasm for everything wild.' Muir's refreshing philosophy of being 'at one' with nature shines through every account he details, as does his agenda for environmental activism - to treat wildness lovingly, rather than selfishly for material greed. Covering mostly the western regions of the states, California, Washington, Nevada, The Grand Canyon, Oregon and Utah; Steep Trails showcases Muir's passion continuously as he climbs mountains, bathes in lakes, and sketches his findings. Muir's classic extended metaphors and knowledgeable tone are present throughout, making for both an enjoyable and educational read. The enthusiasm contained within these pages is infectious, and as well as simply describing the beauty he sees, Muir will inspire you too, to 'go and see for yourselves' the rewards of studying the endless gift of nature: 'Surely faithful and loving skill can go no farther in putting the multitudinous decorated forms on paper. But the colours, the living, rejoicing colours, chanting morning and evening in chorus to heaven! Whose brush or pencil, however lovingly inspired, can give us these? And if paint is of no effect, what hope lies in pen-work? Only this: some may be incited by it to go and see for themselves.'

As Prince William, founder of The Earthshot Prize, said, 'The Earth is at a tipping point and we face a stark choice: either we continue as we are and irreparably damage our planet, or we remember our unique power as human beings and our continual ability to lead, innovate, and problem-solve. People can achieve great things. The next ten years present us with one of our greatest tests - a decade of action to repair the Earth.' The Earthshot concept is simple: Urgency + Optimism = Action. We have ten years to turn the tide on the environmental crisis, but we need the world's best solutions and one shared goal - to save our planet. It's not too late, but we need collective action now. The Earthshots are unifying, ambitious goals for our planet which, if achieved by 2030, will improve life for all of us, for the rest of life on Earth, and for generations to come. They are to: * Protect and Restore Nature * Clean our Air * Revive our Oceans * Build a Waste-Free World * Fix our Climate EARTHSHOT: HOW TO SAVE OUR PLANETis the first definitive book about how these goals can tackle the environmental crisis. It is a critical contribution to the most important story of the decade.

The world's mediterranean-type climate regions (including areas within the Mediterranean, South Africa, Australia, California, and Chile) have long been of interest to biologists by virtue of their extraordinary biodiversity and the appearance of evolutionary convergence between these disparate regions. These regions contain many rare and endemic species. Their mild climate makes them appealing places to live and visit and this has resulted in numerous threats to the species and communities that occupy them. Threats include a wide range of factors such as habitat loss due to development and agriculture, disturbance, invasive species, and climate change. As a result, they continue to attract far more attention than their limited geographic area might suggest. This book provides a concise but comprehensive introduction to mediterranean-type ecosystems. It is an accessible text which provides an authoritative overview of the topic. As with other books in the Biology of Habitats Series, the emphasis in this book is on the organisms that dominate these regions although their management, conservation, and restoration are also considered.

America's Great Plains once possessed one of the grandest wildlife spectacles of the world, equaled only by such places as the Serengeti, the Masai Mara, or the veld of South Africa. Pronghornantelope, gray wolves, bison, coyotes, wild horses, and grizzly bears: less than two hundred years ago these creatures existed insuch abundance that John James Audubon was moved to write, "it is impossible to describe or even conceive the vast multitudesof these animals." In a work that is at once a lyricalevocation of that lost splendor and a detailed natural history of these charismatic species of the historic Great Plains, veterannaturalist and outdoorsman Dan Flores draws a vivid portrait of each of these animals in their glory-and tells the harrowing story of what happened to them at the hands of market hunters and ranchersand ultimately a federal killing program in the nineteenth and twentieth centuries. The Great Plains with its wildlife intact dazzled Americans and Europeans alike, prompting numerous literary tributes. American Serengeti takes its place alongside these celebratory works, showing us the grazers and predators of the plains against the vast opalescent distances, the blue mountains shimmering on the horizon, the great rippling tracts of yellowed grasslands. Far from the empty "flyover country" of recent times, this landscape is alive with a complex ecology at least 20,000 years old-a continental patrimony whose wonders may not be entirely lost, as recent efforts hold out hope of partial restoration of these historic species. Written by an author who has done breakthrough work on the histories of several of these animals-including bison, wild horses, and coyotes-American Serengeti is as rigorous in its research as it isintimate in its sense of wonder-the most deeply informed, closely observed view we have of the Great Plains' wild heritage.

This pioneering book explores the influence of human values on the willingness of individuals to pay for the conservation of individual wildlife species (and classes of these), to be for or against their survival, and to favor or oppose their harvesting.Clement Tisdell combines original theories, survey results and experimental findings to assess the economic benefit of conserving particular wild species and to suggest strategies for a sustainable future. With a detailed analysis of 25 species, covering the three classes (mammals, birds and reptiles), this book examines how variations in knowledge and social factors can influence individuals' evaluation of species. Moreover, economics and ecology are combined to propose sound policies for wildlife management and to provide estimates of the net economic benefit of conserving particular species. The first work to provide such extensive analysis of human values and conservation, this book is an essential resource for economists, ecologists and all those interested in wildlife management, environment and nature conservation. Contents: PART I: BACKGROUND 1. Human values and the conservation of wild species: an overview 2. Basic theory: the economic value of wild species, their conservation and use PART II: VALUES AND SUPPORT FOR THE CONSERVATION OF INDIVIDUAL SPECIES AS WELL AS SUSTAINABLE USE STRATEGIES 3.

There is a growing concern that many important ecosystems, such as coral reefs and tropical rain forests, might be at risk of sudden collapse as a result of human disturbance. At the same time, efforts to support the recovery of degraded ecosystems are increasing, through approaches such as ecological restoration and rewilding. Given the dependence of human livelihoods on the multiple benefits provided by ecosystems, there is an urgent need to understand the situations under which ecosystem collapse can occur, and how ecosystem recovery can best be supported. To help develop this understanding, this volume provides the first scientific account of the ecological mechanisms associated with the collapse of ecosystems and their subsequent recovery. After providing an overview of relevant theory, the text evaluates these ideas in the light of available empirical evidence, by profiling case studies drawn from both contemporary and prehistoric ecosystems. Implications for conservation policy and practice are then examined.

This book focuses on the effects of industrial effluents, specifically those generated from tanneries, on aquatic life i.e. fish. Readers will learn about the impacts of untreated effluents that find its way into potable water bodies, rivers and lakes. A detailed analysis of the morphological and reproductive responses of fish to Chromium VI, a carcinogen and hazardous metal, will be provided. Particular attention is given to the effects of these effluents on the guppy, a fish used for the biological control of malaria. Students and researchers in environmental science, biology, ecology, marine and freshwater sciences will find the book most appealing. Freshwater ecologists working in the field and managers responsible for the protection and monitoring of natural areas will also find this book interesting.

Trees and humans essentially want the same thing - to live good, happy, purposeful lives and to flourish. We are inextricably bound. Trees provide us with the necessities of life - they clean the air we breathe, fill us with awe as we walk through forests and provide timber for the houses we live in, yet there are deeper reasons for our arboreal admiration that go beyond utility and beauty. Tree Glee looks at the psychology behind our fascination with trees, examining exactly how they comfort, restore and revitalise us and what we can learn from the wisdom of woodlands to improve our own wellbeing. It explores the importance of trees in our leafy suburbs and urban landscapes, sharing magical stories of remarkable ancient trees across the globe and inviting readers to reflect on their own personal 'treestory'. Featuring captivating photos and with chapters on forest bathing and nature therapy, woodland wellbeing and tree mythology Tree Glee explores how by deepening our appreciation and connection to trees and by celebrating and protecting them, we can flourish together.

The work summarizes the current knowledge regarding the controlled reproduction of an emerging aquaculture species, the Eurasian perch (Perca fluviatilis). In great detail it describes and explains the principal of most of the controlled reproductive protocol leading to obtain high quality larvae. The book is primarily intended to be used as a hatchery manual by practicing aquaculturists and laboratory technicians working with this species. On the other hand, it also summarizes the scientific background of the methods applied, therefore, it can serve as a reference for the state-of-the-art in the controlled reproduction of Eurasian perch and other freshwater percid species.

The only hope for successful conservation of America's threatened, endangered, and at-risk wildlife is through voluntary, cooperative partnerships that focus on private land, where over 75% of at-risk species can be found. Private landowners form the bedrock of these partnerships, and they have a long history of rising to meet the challenge of conservation. But they can't do it alone. This book is a guide for private landowners who want to conserve wildlife. Whether engaged in farming, ranching, forestry, mining, energy development, or another business, private working lands all have value as wildlife habitat, with the proper management and financial support. This book provides landowners and their partners with a roadmap to achieve conservation compatible with their financial and personal goals. This book introduces the art and language of land management planning as well as regulatory compliance with laws such as the Endangered Species Act of 1973. It categorizes and explains the tools used by wildlife professionals to implement conservation on private lands. Moreover it documents the multitude of federal, state, local, and private opportunities for landowners to find financial and technical assistance in managing wildlife, from working with a local NGO to accessing the $6 billion per year available through the federal Farm Bill.
