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.

'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.'

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.

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.

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.

`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.

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.

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.

This book sheds new light on the causes and consequences of elephant migration in the Panchet Forest Division of Bankura District in West Bengal, India- an area characterized by fragmented forested landscape modified by agriculture and settlement expansion. Anthropogenic activities result in the decline in quality and coverage of forests, loss of biodiversity and removal of forest corridors which ultimately restrict or modify the movement of elephants causing a forceful change of their habitats. A major objective of this monograph is to identify the characteristics of man-elephant conflicts in terms of land use change, cropping patterns, ecological characteristics of the fragmented dry deciduous forest, trends and patterns of elephant migration, and livelihood patterns of the inhabitants in the affected areas. Readers will discover insights into changes in the behavioral pattern of elephants and local people in the conflict ridden zones, and how this influences food selection. Through this book we also learn about rational management strategies that can be employed on the local and national level to mitigate human-elephant conflicts. Ecologists, landscape conservation planners and environmental managers engaged in the conservation of large vertebrates in fragmenting and human-dominated landscapes will find this book valuable.

This volume examines fish sounds that have a proven signal function, as well as sounds assumed to have evolved for communication purposes. It provides an overview of the mechanisms, evolution and neurobiology behind sound production in fishes, and discusses the role of fish sounds in behavior with a special focus on choice of mate, sex-specific and age-specific signaling. Furthermore, it highlights the ontogenetic development of sound communication and ecoacoustical conditions in fish habitats and the influence of hormones on vocal production and sound detection. Sound Communication in Fishes offers a must-have compendium for lecturers, researchers and students working in the fields of animal communication, fish biology, neurobiology and animal behavior.

This volume is an interdisciplinary mix of perspectives and studies on social issues in fisheries from a diverse range of case studies and research disciplines. The case is made regarding the dearth of attention to socio-cultural considerations which to date have been largely treated as an externality of fisheries policy. It will be valuable to researchers and decision makers interested in understanding the social dimension of fisheries and provides a timely and relevant compilation of research and analysis on some of the critical socio-cultural issues facing fisheries management and fishing communities today.

The book provides the most comprehensive review of lamprey biology since Hardisty and Potter's five-volume "The Biology of Lampreys" published more than 30 years ago. Published in two volumes, it includes contributions from international lamprey experts, reviewing and providing new insights into the evolution, general biology, and management of lampreys worldwide. This first volume offers up-to-date chapters on the systematics, general biology, conservation status, and conservation needs of lampreys. It will serve as an important reference for researchers working on any aspect of lamprey biology and fishery managers whose mandate is to control or conserve lamprey populations.

This book is a multidisciplinary analysis of cultural, regional and economic factors affecting international food trade. Contributions from expert authors illuminate the importance of food culture prevailing in the market as a basis for decisions about food trading. Central concepts include value chains, conventions and public infrastructure and their importance for international trade. The reader is taken into a discussion about cultural and economic contexts which influence local decisions among buyers and manufacturers of seafood and how those contexts mutually influence trade between countries. Chapters investigate the trading pattern of codfish (Bacalao), between Nordic and Iberian countries and discuss how business relations are created and structured. The driving forces behind such patterns and how business relations become habits which are hard to change, are revealed through the research presented. As a multidisciplinary work, this book will have broad appeal. It will be of interest to those exploring cultural, economic and public policy issues associated with food trade, as well as anyone with an interest in the seafood market or the Nordic and Iberian regions.

This book provides both the conceptual basis and technological tools that are necessary to identify and solve problems related to biodiversity governance. The authors discuss intriguing evolutionary questions, which involve the sometimes surprising adaptive capacity of certain organisms to dwell in altered and/or changing environments that apparently lost most of their structure and functionality. Space and time heterogeneities are considered in order to understand the patterns of distribution and abundance of species and the various processes that mold them. The book also discusses at which level-from genes to the landscape, including individuals, populations, communities, and ecosystems-men should intervene in nature in order to prevent the loss of biodiversity.

This comprehensive book provides a unique overview of advances in the biology and ecology of marine protists. Nowadays marine protistology is a hot spot in science to disclose life phenomena using the latest techniques. Although many protistological textbooks deal with the cytology, genetics, ecology, and pathology of specific organisms, none keeps up with the quick pace of new discoveries on the diversity and dynamics of marine protists in general. The bookMarine Protists: Diversity and Dynamics gives an overview of current research on the phylogeny, cytology, genomics, biology, ecology, fisheries, applied sciences, geology and pathology of marine free-living and symbiotic protists. Poorly known but ecologically important protists such as labyrinthulids and apostome ciliates are also presented in detail. Special attention is paid to complex interactions between marine protists and other organisms including human beings. An understanding of the ecological roles of marine protists is essential for conservation of nature and human welfare. This book will be of great interest not only to scientists and students but also to a larger audience, to give a better understanding of protists' diverse roles in marine ecosystems.

This book offers a timely and comprehensive review of essential research on Peste des Petits Ruminants Virus (PPRV), ranging from its historical distribution, molecular epidemiology, genome structure, viral proteins, immunity, viral pathogenesis, clinical and molecular diagnosis to advances in vaccine developments and future challenges. PPRV, a Rinderpest-like virus, is the causative agent of one of the most rapidly emerging viral diseases among domestic small ruminants, and the host spectrum has now been expanded to wild small ruminants and camels. With the global eradication of the first livestock disease, Rinderpest, attention is now turning to repeating the procedure for PPR. Each of the book's 13 chapters is dedicated to a specific topic, providing up-to-date literature and discussions by renowned scientists who have made seminal contributions in their respective fields of expertise. Special emphasis has been placed on the analysis of different global efforts to eradicate PPR. This book offers a valuable reference source for virologists, field veterinarians, infection and molecular biologists, immunologists, scientists in related fields and veterinary school libraries.

Biological invasions by alien (non-native) species are widely recognized as a significant component of human-caused global environmental change and the second most important cause of biodiversity decline. Alien species threaten many European ecosystems and have serious environmental, economic and health impacts. The DAISIE (Delivering Alien Invasive Species Inventories for Europe) project has now brought together all available information on alien species in Europe (terrestrial, aquatic and marine) and from all taxa (fungi, plants, animals). Thus for the first time, an overview and assessment of biological invasions in the Pan-European region is finally possible. The Handbook of Alien Species in Europe summarises the major findings of this groundbreaking research and addresses the invasion trends, pathways, and both economic as well as ecological impact for eight major taxonomic groups. Approximately 11.000 alien species recorded in Europe are listed, and fact sheets for 100 of the most invasive alien species are included, each with a distribution map and colour illustration. The book is complemented by a regularly updated internet database providing free additional information. With its highly interdisciplinary approach, DAISIE and its Handbook will be the basis for future scientific investigations as well as management and control of alien invasive species in Europe.

At the beginning of the 21st century, Antarctica is poised at the edge of a warmer and busier world. Leading Antarctic researchers examine the needs and challenges of Antarctic environmental management today and tomorrow. Through: (i) investigating the impacts of human activities on specific ecosystems and species, (ii) examining existing environmental management and monitoring practices in place in various regions and (iii) interrogating stakeholders, they address the following questions: What future will Business-As-Usual bring to the Antarctic environment? Will a Business-As-Usual future be compatible with the objectives set out under the Antarctic Treaty, especially its Protocol on Environmental Protection? What actions are necessary to bring about alternative futures for the next 50 years? This volume is an outcome of the International Polar Year (2007-2009) Oslo Science Conference (8-12, June, 2010).

This book reports significant progress of scientific research on horseshoe crabs, including aspects of evolution, genetics, ecology, population dynamics, general biology and physiology, within the recent 10 years. It also highlights the emerging issues related to world-wide conservation threats, status and needs. The contributions in this book represent part of an ongoing global effort to increase data and concept sharing to support basic research and advance conservation for horseshoe crabs.

Reproductive biology is more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species, technical developments have to be backed up by thorough biological understanding of the background behind the problems. This book is therefore threefold; (1) it provides a snapshot of the state of the art in terms of species-specific reproductive technologies, whether for individual animals or whole taxonomic groups; (2) it sets the reproductive problems in context and emphasizes the links between animal-based problems and the wider world, e.g. reproductive fitness and (3) it looks forward and presents realistic assessments of how effective some of the more recently developed techniques in reproductive technology might be at combating extinctions. This is a wide-ranging book that will be relevant to anyone involved in reproductive biology or in species conservation and provides provide them some useful perspectives about the real utility of current and emerging technologies. It has contributions from experts in reproduction and related fields.

The tropical estuarine systems of Mexico and Central America are an important part of the region´s coastlines; for example Mexico alone possesses more than 770 thousand hectares of mangroves, as well as the largest estuarine mangrove complex on the American Pacific (Marismas Nacionales), yet is one of the poorest studied areas in the world. This is the first book that deals extensively with fisheries management issues in this region from physical-chemistry, ecological and socioeconomic views, providing an understanding on the function and the effects of human activities on these areas, with works undertaken by local scientist.

In the past, wildlife living in urban areas were ignored by wildlife professionals and urban planners because cities were perceived as places for people and not for wild animals. Paradoxically, though, many species of wildlife thrive in these built environments. Interactions between humans and wildlife are more frequent in urban areas than any other place on earth and these interactions impact human health, safety and welfare in both positive and negative ways. Although urban wildlife control pest species, pollinate plants and are fun to watch, they also damage property, spread disease and even attack people and pets. In urban areas, the combination of dense human populations, buildings, impermeable surfaces, introduced vegetation, and high concentrations of food, water and pollution alter wildlife populations and communities in ways unseen in more natural environments. For these ecological and practical reasons, researchers and mangers have shown a growing interest in urban wildlife ecology and management. This growing interest in urban wildlife has inspired many studies on the subject that have yet to be synthesized in a cohesive narrative. Urban Wildlife: Theory and Practice fills this void by synthesizing the latest ecological and social knowledge in the subject area into an interdisciplinary and practical text. This volume provides a foundation for the future growth and understanding of urban wildlife ecology and management by: * Clearly defining th e concepts used to study and describe urban wildlife, * Offering a cohesive understanding of the coupled natural and social drivers that shape urban wildlife ecology, * Presenting the patterns and processes of wildlife response to an urbanizing world and explaining the mechanisms behind them and * Proposing means to create physical and social environments that are mutually beneficial for both humans and wildlife.
