Freshwater ecosystems have the greatest species diversity per unit area and many endangered species. This book shows that, rather than being a marginal part of terrestrial protected area management, freshwater conservation is central to sustaining biodiversity. It focuses on better practices for conserving inland aquatic ecosystems in protected areas, including rivers, wetlands, peatlands, other freshwater and brackish ecosystems, and estuaries. The authors define inland aquatic ecosystems, showing just how diverse and widespread they are. They examine the principles and processes that are essential for the conservation of freshwater ecosystems and aquatic species. Major categories of threats to freshwater ecosystems and the flow-on implications for protected area design are described. Practical case studies are used to illustrate principles and practices applied around the world. Specific management needs of the main types of freshwater ecosystems are considered, as well as the management of freshwaters in the broader landscape, showing how natural resource governance processes can be harnessed to better manage freshwater biodiversity. The book offers commentary on how to adapt freshwater conservation practices to climate change and ends with an insightful synthesis.
This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.
The world relies on very few crop and animal species for agriculture and to supply its food needs. In recent decades, there has been increased appreciation of the risk this implies for food security and quality, especially in times of environmental change. As a result, agricultural biodiversity has moved to the top of research and policy agendas. This Handbook presents a comprehensive overview of our current knowledge of agricultural biodiversity in a series of specially commissioned chapters. It draws on multiple disciplines including plant and animal genetics, ecology, crop and animal science, food studies and nutrition, as well as social science subjects which explore the socio-economic, cultural, institutional, legal and policy aspects of agricultural biodiversity. It focuses not only on the core requirements to deliver a sustainable agriculture and food supply, but also highlights the additional ecosystem services provided by a diverse and resilient agricultural landscape and farming practices. The book provides an indispensable reference textbook for a wide range of courses in agriculture, ecology, biodiversity conservation and environmental studies.
Mudskippers are amphibious fishes native to the Indo-West Pacific and tropical western Africa. Unlike most fishes, mudskippers emerse to forage, find mates, and defend territories. Adaptations to their morphology, physiology and behavior enable mudskippers to accommodate both aquatic and terrestrial habitats. For these traits, mudskippers have long captured the fascination of scientists, naturalists, and fish hobbyists. Some mudskipper taxa (e.g. Periophthalmodon spp., Periophthalmus spp., Boleophthalmus spp.) are readily observed on mudflats and mangrove forests during the ebb tide. Correspondingly, these conspicuous and widespread taxa are relatively well-studied. The autecology and basic biology for the remaing taxa (e.g. Apocryptodon spp. and Oxuderces spp.) are still poorly understood. Fishes Out of Water: Biology and Ecology of Mudskippers is the first comprehensive book to synthesize published scientific information and observation on these fishes. Two dozen subject experts present thorough overviews in fifteen distinct chapters. Contents span mudskipper anatomy, distribution, systematics, physiology, ecology, and conservation. Unique adaptations to terrestriality are discussed within the context of each chapter foci. This authoritative reference equips the reader with the basic foundation to understand mudskipper biology and ecology, while providing a framework in which emerging data are discussed. The book will be of interest to a broad range of students, researchers, and professionals in ichthyology, evolution, ecology, animal behavior, and comparative physiology.
How did we get here? All cultures have a creation story, but a little over 150 years ago Charles Darwin introduced a revolutionary new one. We, and all living things, exist because of the action of evolution on the first simple life form and its descendants. We now know that it has taken 3.8 billions of years of work by the forces of evolution to turn what was once a lump of barren rock into the rich diversity of into plants, animals and microbes that surround us. In the process, evolution has created all manner of useful adaptions, from biological computers (brains) to a system to capture energy from the sun (photosynthesis). But how does evolution actually work? In Evolution, leading biologists and New Scientist take you on a journey of a lifetime, exploring the question of whether life is inevitable or a one-off fluke, and how it got kick-started. Does evolution have a purpose or direction? Are selfish genes really the driving force of evolution? And is evolution itself evolving? ABOUT THE SERIES New Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds. Designed for curious readers who want to know how things work and why, the Instant Expert series explores the topics that really matter and their impact on individuals, society, and the planet, translating the scientific complexities around us into language that's open to everyone, and putting new ideas and discoveries into perspective and context.
Ecological restoration is a rapidly evolving discipline that is engaged with developing both methodologies and strategies for repairing damaged and polluted ecosystems and environments. During the last decade the rapid pace of climate change coupled with continuing habitat destruction and the spread of non-native species to new habitats has forced restoration ecologists to re-evaluate their goals and the methods they use. This comprehensive handbook brings together an internationally respected group of established and rising experts in the field. The book begins with a description of current practices and the state of knowledge in particular areas of restoration, and then identifies new directions that will help the field achieve increasing levels of future success. Part I provides basic background about ecological and environmental restoration. Part II systematically reviews restoration in key ecosystem types located throughout the world. In Part III, management and policy issues are examined in detail, offering the first comprehensive treatment of policy relevance in the field, while Part IV looks to the future. Ultimately, good ecological restoration depends upon a combination of good science, policy, planning and outreach - all issues that are addressed in this unrivalled volume.
The Great Barrier Reef is located along the coast of Queensland in north-east Australia and is the world's largest coral reef ecosystem. Designated a World Heritage Area, it has been subject to increasing pressures from tourism, fishing, pollution and climate change, and is now protected as a marine park. This book provides an original account of the environmental history of the Great Barrier Reef, based on extensive archival and oral history research. It documents and explains the main human impacts on the Great Barrier Reef since European settlement in the region, focusing particularly on the century from 1860 to 1960 which has not previously been fully documented, yet which was a period of unprecedented exploitation of the ecosystem and its resources. The book describes the main changes in coral reefs, islands and marine wildlife that resulted from those impacts. In more recent decades, human impacts on the Great Barrier Reef have spread, accelerated and intensified, with implications for current management and conservation practices. There is now better scientific understanding of the threats faced by the ecosystem. Yet these modern challenges occur against a background of historical levels of exploitation that is little-known, and that has reduced the ecosystem's resilience. The author provides a compelling narrative of how one of the world's most iconic and vulnerable ecosystems has been exploited and degraded, but also how some early conservation practices emerged.
Neotropical Biogeography: Regionalization and Evolution presents the most comprehensive single-source treatment of the Neotropical region derived from evolutionary biogeographic studies. The book provides a biogeographic regionalization based on distributional patterns of plant and animal taxa, discusses biotic relationships drawn from track and cladistic biogeographic analyses, and identifies cenocrons (subsets of taxa within biotas identified by their common origin and evolutionary history). It includes maps, area cladograms and vegetation profiles. The aim of this reference is to provide a biogeographic regionalization that can be used by graduate students, researchers and other professionals concerned with understanding and describing distributional patterns of plants and animals in the Neotropical region. It covers the 53 biogeographic provinces of the Neotropical region that are classified into the Antillean, Brazilian and Chacoan subregions, and the Mexican and South American transition zones.
Ever since the concept of the "struggle for life" became the heart of Darwin's theory of evolution, biologists have studied the relevance of interactions for the natural history and evolution of organisms. Although positive interactions among plants have traditionally received little attention, there is now a growing body of evidence showing the effects of positive interactions between higher plant species. Written by international experts, Positive Plant Interactions and Community Dynamics reviews these developments with particular emphasis on positive interactions and spatial and temporal gradients. The text addresses key issues in plant ecology and anthropogenic impacts through reviews, syntheses, and the proposition of new concepts. The book begins with coverage of the different approaches used over time and the tools currently available for analyzing the direction, intensity, and importance of plant interactions, and to quantify them accurately. It explains, at least in part, the success of invasive plant species. The book also shows the existence of evolutionary relationships among plants, a decidedly non-individualistic process, which plays an important role in the organization of communities. The book's focus then shifts to the scale at which facilitation works, assessing its effects from the individual plant to the landscape level, and the impacts of climate change on plant-plant interactions using case studies to illustrate underlying fundamental points relevant to all plant communities. After analyzing the role of positive and negative interactions and their relationship with biodiversity and ecosystem functioning, the text reviews the role of mychorrizal symbiosis in plant-plant interactions, focusing on the effect of mychorhizal-mediated facilitation on the structure and dynamics of plant communities. A good understanding of natural processes is necessary to manage natural habitats properly, prevent environmental risks, and secure continued ecosystem services. Clearly and concisely written, this book challenges the paradigm that interactions should be considered independently, with little regard to context. Addressing the complex processes at the foundation of ecosystem diversity, the book promotes more rigorous experimental design and opportunities for further research developments in this field.
The overarching contribution of this book is a review and assessment of the current and future impacts of globalization on the world's forests. The work has been developed by the "Resources for the Future" Task Force for the International Union of Forest Research Organizations (IUFRO). Four key themes are addressed: the effect of globalization on forests (including future trade flows); plantations as the primary source of forest products and its consequences, including plant breeding and forest health; the effect of new products such as bio-products and markets on forests; and the emergence of forest ecosystem services and their impact on the landscape and human communities. These four themes are examined in detail to map out the impacts of these trends for forests throughout the world and at multiple scales, and how forest research needs to be adapted to address these trends. Overall, the volume provides a major synthesis of current thinking and knowledge on the topic for advanced students, as well as policy-makers and professionals in the forest sector.
How does life work? How does nature produce the right numbers of zebras and lions on the African savanna, or fish in the ocean? How do our bodies produce the right numbers of cells in our organs and bloodstream? In The Serengeti Rules, award-winning biologist and author Sean Carroll tells the stories of the pioneering scientists who sought the answers to such simple yet profoundly important questions, and shows how their discoveries matter for our health and the health of the planet we depend upon. One of the most important revelations about the natural world is that everything is regulated--there are rules that regulate the amount of every molecule in our bodies and rules that govern the numbers of every animal and plant in the wild. And the most surprising revelation about the rules that regulate life at such different scales is that they are remarkably similar--there is a common underlying logic of life. Carroll recounts how our deep knowledge of the rules and logic of the human body has spurred the advent of revolutionary life-saving medicines, and makes the compelling case that it is now time to use the Serengeti Rules to heal our ailing planet. A bold and inspiring synthesis by one of our most accomplished biologists and gifted storytellers, The Serengeti Rules is the first book to illuminate how life works at vastly different scales. Read it and you will never look at the world the same way again.
Loss of biodiversity is one of the great environmental challenges facing humanity but unfortunately efforts to reduce the rate of loss have so far failed. At the same time, these efforts have too often resulted in unjust social outcomes in which people living in or near to areas designated for conservation lose access to their territories and resources. In this book the author argues that our approach to biodiversity conservation needs to be more strongly informed by a concern for and understanding of social justice issues. Injustice can be a driver of biodiversity loss and a barrier to efforts at preservation. Conversely, the pursuit of social justice can be a strong motivation to find solutions to environmental problems. The book therefore argues that the pursuit of socially just conservation is not only intrinsically the right thing to do, but will also be instrumental in bringing about greater success. The argument for a more socially just conservation is initially developed conceptually, drawing upon ideas of environmental justice that incorporate concerns for distribution, procedure and recognition. It is then applied to a range of approaches to conservation including benefit sharing arrangements, integrated conservation and development projects and market-based approaches such as sustainable timber certification and payments for ecosystem services schemes. Case studies are drawn from the author's research in Rwanda, Uganda, Tanzania, Laos, Bolivia, China and India.
National implementation of the Convention on Biological Diversity (CBD) provisions has yielded enough challenges for providers and users of genetic resources and associated traditional knowledge alike. The Nagoya Protocal brings novel ideas for resolving the challenges plaguing the Access and Benefit-Sharing (ABS) process in general and non-commercial research in particular. This is one of the first books to address research cooperation and facilitated access for non-commercial biodiversity research. It uniquely offers concrete and practicable solutions based on experiences of researchers and administrative officials with ABS, and on the interpretation of the Nagoya Protocol on how free and lively taxonomic research can be ensured while at the same time observing obligations of obtaining prior informed consent and sharing of benefits. This book will be useful to students of International Environmental Law, International Biodiversity Law, Intellectual Property Law, Climate Law and Law of Indigenous Populations. With foreword from Executive Secretary CBD, Braulio Ferreira de Souza Dias.
Ecotoxicology and Chemistry Applications in Environmental Management describes how to set up an integrated, holistic approach to addressing ecotoxicological problems. It provides detailed explanations in answer to questions like "Why is it necessary to apply an integrated approach?" and "How does one apply an integrated environmental management approach?" Highlighted topics of the book include Environmental chemical calculations QSAR estimation methods Toxic substance interference with other environmental problems Using diagnostic ecological subdisciplines for solutions Cleaner production methods and technologies Environmental risk assessment Addressing one of the most difficult tasks today, this book provides a much-needed holistic view for translating scientific knowledge and research results into effective environmental management measures. Rooted in a seven-step method, it integrates examination and quantification of an environmental problem and describes the use of ecological diagnostic tools to develop a diagnosis for ecosystem health. It also presents methods for choosing and using solutions or combinations of solutions to tackle problems.
There is a growing demand for appropriate management of aquatic invasive species in lakes and rivers worldwide. This book covers biology, invasion ecology, sightings, and control techniques of 4 invasive animals and 15 invasive plants in Massachusetts lakes and rivers. It provides valuable information on their biological characteristics and potential expansion pathways, as well as monitoring and management, including alternative management tools using updated biological, chemical, and mechanical methods. The book also includes the regulation of invasive species management to allow resource managers, biologists, practitioners, volunteers, and students a better understanding of compliance and enforcement with environmental law. An example of successful management is highlighted for each invasive species. Invasive Animals and Plants in Massachusetts Lakes and Rivers is the first book to provide comprehensive and systematic coverage and illustrations for both freshwater invasive animals and plants. Although focussing on Massachusetts, it will provide readers with the bigger picture on multiple invasive species, from prevention, early detection, control, ecological restoration, to public education. Natural resource managers in Massachusetts and surrounding states will glean the detailed and valuable information they need to learn and use to prevent and manage freshwater invasive species in the field.
The Theraphosidae are the most famous and diverse mygalomorph spiders, and include some of the largest arachnids on earth. Their unique defense mechanisms, predatory tactics, reproductive strategies and ecological adaptations are displayed by a wide range of terrestrial, burrowing and arboreal species. These arachnids are familiar to the general public thanks to horror movies and a growing interest in tarantulas as pets; however, scientific information on the group is scattered throughout the literature and not easily available. This book reviews all major aspects of New World Theraphosid tarantulas and provides in-depth information on their evolution, taxonomy, behavior, physiology, ecology, reproduction, conservation and biogeography. As a comprehensive guide to the biology of tarantulas, it will appeal to researchers, students and terrarium hobbyists alike.
Shortlisted for the 2018 TWS Wildlife Publication Awards in the edited book category Lesser Prairie-Chickens have experienced substantial declines in terms of population and the extent of area that they occupy. While they are an elusive species, making it difficult at times to monitor them, current evidence indicates that they have been persistently decreasing in number since the Dust Bowl of the 1930s dramatically affected their core range. In May of 2014, the United States Fish and Wildlife Service listed Lesser Prairie-Chickens as a threatened species, granting them federal protection under the Endangered Species Act, which included a special rule recognizing significant conservation planning efforts made by state and federal wildlife agencies within the geographical range of the species. Although the listing was vacated by judicial ruling in September 2015, concern for persistence of the species persists. These actions illustrate the uncertain legal status and future conservation challenges for Lesser Prairie-Chickens. Ecology and Conservation of Lesser Prairie-Chickens provides a compendium of data, analytical results, and synthesis generated among expert wildlife biologists, conservation biologists, and ornithologists. It thoroughly reviews the life history, genetics, and ecology of the species, and is ultimately directed toward developing and establishing appropriate conservation management strategies. It presents a detailed analysis of the issues and risks relative to conservation as well as an overview of potential conservation tools. It also addresses the challenges that natural resource managers continue to face in their current conservation efforts. While dealing with immediate and short-term issues in Lesser Prairie-Chicken conservation, this book is also a useful starting point for guiding future research, management, and conservation of the species. Published in collaboration with and on behalf of The American Ornithological Society, this volume in the highly-regarded Studies in Avian Biology series provides a definitive reference for researchers, managers, and policy makers as well as those with interests in environmental science, avian biology, game bird management, or Great Plains ecology.
Using more than 30 years research from the author team at the Wildlife Conservation Research Unit (WildCRU), this volume reveals how agricultural systems and wildlife interact, presenting examples from scales varying from landscape to microcosm, from populations to individuals, covering plants, invertebrates, birds, and mammals. It demonstrates the essential ecosystem services provided by agricultural land, and discusses the implications of agricultural development for natural habitats and biodiversity.
Mutualisms, interactions between two species that benefit both of them, have long captured the public imagination. Their influence transcends levels of biological organization from cells to populations, communities, and ecosystems. Mutualistic symbioses were crucial to the origin of eukaryotic cells, and perhaps to the invasion of land. Mutualisms occur in every terrestrial and aquatic habitat; indeed, ecologists now believe that almost every species on Earth is involved directly or indirectly in one or more of these interactions. Mutualisms are essential to the reproduction and survival of virtually all organisms, as well as to nutrient cycles in ecosystems. Furthermore, the key ecosystem services that mutualists provide mean that they are increasingly being considered as conservation priorities, ironically at the same time as the acute risks to their ecological and evolutionary persistence are increasingly being identified. This volume, the first general work on mutualism to appear in almost thirty years, provides a detailed and conceptually-oriented overview of the subject. Focusing on a range of ecological and evolutionary aspects over different scales (from individual to ecosystem), the chapters in this book provide expert coverage of our current understanding of mutualism whilst highlighting the most important questions that remain to be answered. In bringing together a diverse team of expert contributors, this novel text captures the excitement of a dynamic field that will help to define its future research agenda.
The Southern Ocean surrounding the Antarctic continent is vast, in particular, its history, its isolation, and climate, making it a unique "laboratory case" for experimental evolution, adaptation and ecology. Its evolutionary history of adaptation provide a wealth of information on the functioning of the biosphere and its potential. The Southern Ocean is the result of a history of nearly 40 million years marked by the opening of the Straits south of Australia and South America and intense cooling. The violence of its weather, its very low temperatures, the formation of huge ice-covered areas, as its isolation makes the Southern Ocean a world apart. This book discusses the consequences for the evolution, ecology and biodiversity of the region, including endemism, slowed metabolism, longevity, gigantism, and its larval stages; features which make this vast ocean a "natural laboratory" for exploring the ecological adaptive processes, scalable to work in extreme environmental conditions. Today, biodiversity of the Southern Ocean is facing global change, particularly in regional warming and acidification of water bodies. Unable to migrate further south, how will she cope, if any, to visitors from the North?
Islands have an irresistible attraction and an enduring appeal. Naturalist Roger Lovegrove has visited many of the most remote islands in the world, and in this book he takes the reader to twenty that fascinate him the most. Some are familiar but most are little known; they range from the storm-bound island of South Georgia and the ice-locked Arctic island of Wrangel to the wind-swept, wave-lashed Mykines and St Kilda. The range is diverse and spectacular; and whether distant, offshore, inhabited, uninhabited, tropical or polar, each is a unique self-contained habitat with a delicately-balanced ecosystem, and each has its own mystique and ineffable magnetism. Central to each story is also the impact of human settlers. Lovegrove recounts unforgettable tales of human endeavour, tragedy, and heroism. But consistently, he has to report on the mankind's negative impact on wildlife and habitats - from the exploitation of birds for food to the elimination of native vegetation for crops. By looking not only at the biodiversity of each island, but also the uneasy relationship between its wildlife and the involvement of man, he provides a richly detailed account of each island, its diverse wildlife, its human history, and the efforts of conservationists to retain these irreplaceable sites.
A personal account of—and guide to—unlocking the wildlife potential of gardens and other plots of land in lowland Britain Over the past decade, wildlife author and photographer Paul Sterry has nurtured, both through action and by doing nothing, what has become a small island of flourishing biodiversity in the half-acre garden that surrounds his north Hampshire cottage. By giving nature a free hand, and fostering habitats appropriate to this part of southeast England, he has enabled an abundance of native plant and animal species to call the garden home. This contrasts with the continued decline in biodiversity in the surrounding countryside. In this inspiring and informative book, Sterry tells the story of his own experiences in biodiversity gardening and offers detailed practical advice to anyone who wants to give nature the upper hand on their own bit of land, no matter how small. Hampshire still retains traces of its rich wildlife heritage, but changes in land use over the past half-century have had a devastating impact on local biodiversity. Against this backdrop, The Biodiversity Gardener presents a habitat-driven and evidence-based approach, describing how any gardener can unlock the wildlife potential of their plot and enjoy the satisfaction of watching it become home to a rich array of native species, including butterflies, wildflowers, grasshoppers, amphibians, and fungi. In The Biodiversity Gardener, Sterry explains the ecological imperative of adopting this approach. Collectively, biodiversity gardens could leave a lasting legacy—wildlife oases from which future generations stand a fighting chance of restoring Britain’s natural heritage. The book encourages and empowers readers to create their own biological inheritance for posterity—and shows them how they can do it.
South Africa's fynbos region has intrigued biologists for centuries. It has achieved iconic status as a locus of megadiversity and therefore a place to study the ecological underpinnings of massive evolutionary radiations. Researchers have made great advances over the past two decades in unravelling the complexities of fynbos ecology and evolution, and the region has contributed significant insights into the adaptive radiations of large lineages, conservation science, pollination biology, invasive plant biology, and palaeoanthropology. Lessons from the fynbos offer much of value for understanding the origin, maintenance, and conservation of diversity anywhere in the world. This book provides the first synthesis of the field for 20 years, bringing together the latest ecological and evolutionary research on the South African global biodiversity hotspots of the Greater Cape Floristic Region - the iconic fynbos and succulent karoo. It explores the historical and modern physical and biological environment of this region, the circumstances and processes which have fostered its remarkable biodiversity, and the role this diversity has played in the emergence of modern humans. It also discusses the challenges of contemporary management and conservation of the region's biodiversity in the face of accelerating global change.
Marine sediments dominate the global seabed, creating the largest ecosystem on earth. Seafloor biodiversity is a key mediator of ecosystem functioning, yet critical processes are often excluded from global biogeochemical budgets or simplified to black boxes in ecosystem models. This accessible textbook provides an ideal point of entry into the field, providing basic information on the nature of soft-sediment ecosystems, examples of how and why we research them, the new questions these studies inspire, and the applications that ultimately benefit society. While focussing on coastal habitats (<200m depth) to emphasize process-based experimental studies, it is relevant to the full range of marine sedimentary habitats. The authors describe the interactions between marine organisms and their physical and chemical environment, demonstrating the need for carefully designed research programs and providing the basic steps required to formulate sound ecological questions before applying them to empirical studies of real-world ecosystems. The book reveals the connections between different system components and drivers of change, examining how we can develop knowledge on the biodiversity and functioning of soft sediments and apply it to a better understanding of ecosystem change, human impacts, and effective restoration. Ecology of Coastal Marine Sediments is intended for advanced undergraduate and graduate students who have completed a general ecology course but received no further training in marine science. It will also be useful to both professional researchers and resource managers in marine ecology and environmental science who seek a compact and authoritative introduction to sediment ecology.
