Lands lost to desert may effectively be lost for ever, so desertification is humanity's most obvious despoliation to the planet. It is certainly one of the most serious environmental problems facing the world today. In this book the author describes what is happening and where. Although the problem is greatest in developing countries, it is by no means confined to them. Australia, Africa, the USA and India are all affected. In the 1970s an international Plan of Action was drawn up to bring the phenomenon under control, but it was never implemented. Now that the situation is more serious than ever before, this book urges new action and describes many of the myriad ways in which it is possible to arrest the progress of desertification. It describes, too, not just the failures, but the considerable successes that have been achieved. Originally published in 1990

In the past decade, the growing realization that biodiversity and human wellbeing are inextricably linked has led to the adoption of numerous environmental policies. The concept of the Green Economy has gained particular attention as an economic system where growth is possible within environmental limits. The preservation of ecosystem services and the halt of biodiversity loss are identified as key pillars of the Green Economy. Despite the concept's momentum there is still no clear understanding of how biodiversity fits within a Green Economy. In the current debate, biodiversity is rarely acknowledged in economic sectors other than agriculture, forestry, fisheries and tourism, and when it is acknowledged biodiversity and its conservation feature more as buzzwords than as concrete and tangible components of the Green Economy. This book aims to identify, understand and offer pragmatic recommendations of how biodiversity conservation can become an agent of green economic development. This book establishes ways to assess biodiversity's contributions to the economy and to meaningfully integrate biodiversity concerns in green-economy policies.

Nonlinear Physics of Ecosystems introduces the concepts and tools of pattern formation theory and demonstrates their utility in ecological research using problems from spatial ecology. Written in language understandable to both physicists and ecologists in most parts, the book reveals the mechanisms of pattern formation and pattern dynamics. It also explores the implications of these mechanisms in important ecological problems. The first part of the book gives an overview of pattern formation and spatial ecology, showing how these disparate research fields are strongly related to one another. The next part presents an advanced account of pattern formation theory. The final part describes applications of pattern formation theory to ecological problems, including self-organized vegetation patchiness, desertification, and biodiversity in changing environments. Focusing on the emerging interface between spatial ecology and pattern formation, this book shows how pattern formation methods address a variety of ecological problems using water-limited ecosystems as a case study. Readers with basic knowledge of linear algebra and ordinary differential equations will develop a general understanding of pattern formation theory while more advanced readers who are familiar with partial differential equations will appreciate the descriptions of analytical tools used to study pattern formation and dynamics.

Elizabeth H. Petersen argues that economists and other social scientists are increasingly focusing their attention towards institutions (defined as humanly-devised rules) as critical determinants of economic, social and political growth and development. Institutions responsible for the governance of fishery resources have experienced dramatic reforms over the last few decades, stimulated by increased competition for access and exploitation of resources, leading to emerging scarcity of these very resources. This book aims to contribute to the biological and economic sustainability of fish resources worldwide by providing an analysis of fisheries management in the context of new institutional economics. The book's premise is that sound fisheries management requires a clear definition of policy goals for the fishery, such as long-term biological sustainability and maximization of sustainable economic returns, and the subsequent development of institutions capable of aiding and achieving these policy goals. Without such policies and institutions, the author illustrates, there is likely to be continued resource conflict as well as biological and economic over-exploitation. This book provides an innovative institutional framework for managing multilateral fisheries and includes suggestions for solving specific fisheries problems, such as managing fishery revenues and trading cheap fisheries access for foreign aid. The book concludes with a discussion of the importance of economic growth and development, as well as broader socio-economic institutions for fisheries. As such, it will be of enormous interest to environmentalists, ecologists, policymakers, scholars and practitioners focusing on fisheries management.

Insects represent the most abundant and diverse animal group on Earth. The number of described species is more than one million and up to ten million are estimated. Insects have one of the widest distributions in the world because they have adapted to extreme ranges of environments.

Molecular ecology studies ecological processes based on the analysis of biomacromolecules, particularly DNA, RNA, and proteins, but also of low-molecular weight signal compounds. Molecular ecology uses the exciting opportunities offered by the tools of molecular biology.

The book presents current entomological research, where molecular tools help to advance traditional ecological studies. Chapters include ones on insect insect and insect plant interactions, on mechanisms of environmental adaptation, or on the use of insect biotechnology in pest and vector control. The book helps to combine powerful methods in molecular biology with exciting issues in ecology to understand why insects became "masters of survival.""

This wonderful book demonstrates how rural livelihoods - as well as diets, health and ways of life - are enhanced by the so-called neglected and underutilized plant species which, in the book s Syrian case study, include such deliciously interesting things as capers, laurel, jujube and figs. Using value chain analysis the author illuminates the opportunities for strengthening arid land economies with attention to such species, while simultaneously maintaining the diversity and integrity of those plant genomes, landscapes and cultures. And keeping the world worth tasting. KEN WILSON, EXECUTIVE DIRECTOR OF THE CHRISTENSEN FUND Alexandra Giuliani delivers a convincing and very practical account of how biodiversity products derived from neglected and underutilized plant species enter the markets in Syria. By highlighting the value of these plant products for the family income and health status of marginal farmer families in rural drylands and semi-arid areas, she brings the message home as to why it is so important to maintain biodiversity of the genetic resources not by protection alone, but rather through their judicious use. KATHARINA JENNY, SENIOR ADVISOR, FEDERAL DEPARTMENT OF FOREIGN AFFAIRS, SWISS AGENCY FOR DEVELOPMENT AND COOPERATION Just four crops - maize, potatoes, rice and wheat - provide more than 90 per cent of the world s food. Old varieties of even these crops are disappearing as farmers and consumers strive for more uniformity in food products. This in turn affects less obvious elements, such as insects that play a role in pollinating plants or controlling pests and the soil organisms that help plants extract nutrients from the soil. Also, farmers need a broad base of agrobiodiversity to be able to respond and adapt to environmental changes and to improve their production. This is especially important in the face of climate change and changing economic and political pressures. This book from Bioversity International describes a study conducted in Syria of how communities are developing markets for local products derived from neglected and underutilized plants. Based on concrete case studies, the data and processes documented in this book show the potential of biodiversity to make a significant contribution to livelihood security in communities that inhabit difficult environments with unique resources. The study also highlights the importance of local cultural knowledge and institutions in sustainable development of biodiversity markets. Published with Bioversity International."

An important first step in studying the demography of wild animals is to identify the animals uniquely through applying markings, such as rings, tags, and bands. Once the animals are encountered again, researchers can study different forms of capture-recapture data to estimate features, such as the mortality and size of the populations. Capture-recapture methods are also used in other areas, including epidemiology and sociology. With an emphasis on ecology, Analysis of Capture-Recapture Data covers many modern developments of capture-recapture and related models and methods and places them in the historical context of research from the past 100 years. The book presents both classical and Bayesian methods. A range of real data sets motivates and illustrates the material and many examples illustrate biometry and applied statistics at work. In particular, the authors demonstrate several of the modeling approaches using one substantial data set from a population of great cormorants. The book also discusses which computer programs to use for implementing the models and contains 130 exercises that extend the main material. The data sets, computer programs, and other ancillaries are available at www.capturerecapture.co.uk. The book is accessible to advanced undergraduate and higher-level students, quantitative ecologists, and statisticians. It helps readers understand model formulation and applications, including the technicalities of model diagnostics and checking.

Animal welfare has long been recognised as central to the role of the veterinary professional, but this is increasingly aligned with the welfare of humans and the broader environment in which we co-exist. This is the first book dedicated to the role of the veterinarian in One Welfare, a concept that recognises the interconnections between animal welfare, human wellbeing, and the environment. The book demonstrates, through a wide range of international case studies, why professional ethics and the use of good evidence is integral to this role. Contributors bring a rich variety of writings, each with their own perception of the role of the veterinarian in improving animal welfare and human wellbeing. One Welfare in Practice: The Role of the Veterinarian emphasises the importance of interdisciplinary collaboration and solutions: it is essential that veterinary practitioners recognise when other professionals or disciplines need to be consulted to benefit both animals and humans. With its multiple, fascinating approaches to One Welfare, this book will inform and inspire the veterinarian to find areas where collaborative action reaps the greatest rewards. This unique book shows how veterinarians can and are contributing to improving animal and human welfare, offering practical advice as to how the profession can further engage in One Welfare in a range of settings.

This book spells out the theoretical structure, methodology and philosophy of the science of autecology. The autecological approach focuses on the interactions of individual organisms (and their species-specific adaptations) with the spatio-temporal dynamics of their environment as a basis for interpreting patterns of diversity and abundance in natural systems. This organism-based approach to ecological interpretation provides a strong alternative to more traditional approaches and relates mechanistically to the underlying disciplines of anatomy, physiology, and behavior. The book includes illustrations, specific examples, graphs, maps, and other diagrams.

The RSPB's Book of the Season The distinctive white-tailed sea eagle was driven to extinction in Britain more than 200 years ago, but this immense predator is making a return to our skies, thanks to Roy Dennis, an ornithologist, conservationist and arguably the driving force behind the UK's reintroduction agenda. Roy was instrumental in returning the Osprey, red kite and golden eagle to the British Isles, but the road to reintroduction isn't an easy one. In what will surely be the seminal book on British reintroductions, Roy details the painstaking process of returning the Goldeneye to Scotland, one duckling at a time, the die-hard determination needed to make a dazzling success of the red kite reintroduction and the leap of faith we will all need to make to accept sharing our forests and skies with large carnivores again. He also illustrates all that we have to gain by restoring our ecosystems to balance. Filled with a lifetime's worth of stories from the front lines of conservation, Reintroduction offers an eye-opening insight into the complexities of reintroducing extinct animals to Britain. It's also an intimate portrait of these apex predators and a reminder of why we need them.

Forest insects play important roles ecologically and economically. They pollinate plants, decompose dead plant and animal tissue, provide food for vertebrates, regulate pest organisms and shape entire landscapes. Some are considered pests, while others provide usable products. Introduced species may become invasive, while the survival of others is threatened. Forest Insects in Europe: Diversity, Functions and Importance has been written not only with professional entomologists in mind, but also for nature lovers generally. The descriptions of the various roles insects play in forest ecosystems are intended to be easily comprehensible, but still scientific. The book is richly illustrated with attractive photos and contains 580 fascinating colour images of more than 300 different insect and spider species. The German edition was awarded the Prix Moulines by the Swiss Entomological Society in 2019.

The authors have done an outstanding job of compiling decades of data collected by their own field reconnaissance and other geoscientists... This represents a significant contribution to the understanding of the development of the Florida carbonate platform, and it will assist other disciplines as they strive for better understanding of our groundwater resources, aquifer characterizations, paleoenvironmental interpretations, and historical/educational geology programs. Walt Schmidt, Florida State Geologist & Chief, Florida Geological Survey, USA (praise for the first edition) Painting a complete picture of the history of the Everglades, Ancient Seas of Southern Florida: The Geology and Paleontology of the Everglades Region, Second Edition provides an overview of the geology, paleontology, and paleoceanography of the region. It emphasizes the upper 300m of the geologic framework of the area and gives insight into the local stratigraphy, geomorphology, lithology, and historical geology. Designed to be a field guide as well as a reference, the book is illustrated in full color with brand new photographs of exposed geologic sections, stratotype localities, collection sites, and details of interesting fossil beds. In this book, the authors illustrate almost 800 of the most important and diagnostic stratigraphic index fossils found in these beds, including over 50 species of corals and almost 700 species of mollusks, along with echinoderms, crustaceans, echinoids, petrified wood, and aquatic vertebrates. A new edition of The Geology of the Everglades and Adjacent Areas, it contains larger images of fossil shells, corals, and echinoderms and includes new updated geological data and concepts, as well as an expanded iconography of stratigraphic index fossils. Based on the data gleaned from these fossils, it also offers a series of geomorphological visualizations, showing the possible appearances of the Florida Peninsula during the times when it was covered by tropical seas, from the Oligocene to the late Pleistocene. This second edition provides a new perspective on both the historical geology of southern Florida and the evolution of one of America's most beautiful natural treasures, the Everglades.

Bees are flying insects of the order Hymenoptera closely related to wasps and ants. The ancestors of bees are assumed to be predatory wasps, which switched to pollen consumption. Further, bees co-evolved with flowering plants and divided into several species according to climatic conditions. Widely known bees are western bees Apis mellifera, and eastern bees Apis cerana. This book sheds light on features of evolution, phylogenesis, speciation, adaptation to environment, and taxonomy of bees. It will be of particular relevance to evolutionists, geneticists, taxonomists, ecologists, population geneticist, and breeders.

This book summarizes and analyzes the biology, ecology, exploitation and management of small cetaceans in Japan. It describes the various types of cetacean fisheries in Japan and their historical development, the life histories and ecologies of the main species involved, and the history and problems of conservation and management. The data show that in some cases the number of small cetaceans harvested exceed sustainable limits and have led to depletion of populations. The book provides a case study of what can go wrong when the needs of industry and conservation collide. The descriptions of life history and ecology are relevant to issues of conservation and management, not just for cetaceans, but for all fisheries around the world.

Communicating Endangered Species: Extinction, News, and Public Policy is a multidisciplinary environmental communication book that takes a distinctive approach by connecting how media and culture depict and explain endangered species with how policymakers and natural resource managers can or do respond to these challenges in practical terms. Extinction isn't new. However, the pace of extinction is accelerating globally. The International Union for Conservation of Nature classifies more than 26,000 species as threatened. The causes are many, including climate change, overdevelopment, human exploitation, disease, overhunting, habitat destruction, and predators. The willingness and the ability of ordinary people, governments, scientists, nongovernmental organizations, and businesses to slow this deeply disturbing acceleration are uncertain. Meanwhile, researchers around the world are laboring to better understand and communicate the possibility and implications of extinctions and to discover effective tools and public policies to combat the threats to species survival. This book presents a history of news coverage of endangered species around the world, examining how and why journalists and other communicators wrote what they did, how attitudes have changed, and why they have changed. It draws on the latest research by chapter authors who are a mix of social scientists, communication experts, and natural scientists. Each chapter includes a mass media and/or cultural aspect. This book will be essential reading for students, natural resource managers, government officials, environmental activists, and academics interested in conservation and biodiversity, environmental communication and journalism, and public policy.

Access to genetic resources and Benefit Sharing (ABS) has been promoted under the Convention on Biological Diversity, with the aim of combining biodiversity conservation goals with economic development. However, as this book shows, since its inception in 1992, implementation has encountered multiple challenges and obstacles. This is particularly so in the marine environment, where interest in genetic resources for pharmaceuticals and nutrients has increased. This is partly because of the lack of clarity of terminology, but also because of the terms of the comprehensive law of the sea (UNCLOS) and transboundary issues of delineating ownership of marine resources. The author explains and compares relevant provisions and concepts under ABS and the law of the sea taking access, benefit sharing, monitoring, compliance, and dispute settlement into consideration. He also provides an overview of the implementation status of ABS-relevant measures in user states and identifies successful ABS transactions. A key unique feature of the book is to illustrate how biological databases can serve as the central scientific infrastructure to implement the global multilateral benefit sharing mechanism, proposed by the Nagoya Protocol. The research for this book was supported by both the Bremen International Graduate School for Marine Sciences (GLOMAR) and the International Research Training Group INTERCOAST - Integrated Coastal Zone and Shelf-Sea Research.

Vertebrate invasive species are important ecologically, socially, and scientifically throughout much of the globe. However, the interdiction and options for management of invasive species are driven by localized regulation at the country or even state level and thus the management of species must be framed within that context. This book is focused around the management of invasive vertebrate species in the United States, although readers will find much of the material broadly applicable to invasive species in other regions. Vertebrate invasive species cause damage to agriculture, property, natural resources, and threaten human health and safety. However, most of these species occur in the United States resulting from human-mediated activities, often being released intentionally. For the first time, the wealth of scientific information about vertebrate invasive species in the United States is summarized and synthesized in a single volume to be easily accessible to ecologists and natural resource managers. With a focus on prominent terrestrial invasive species that have a history of policy and management and highlighting contemporary issues and management, this book consists of 18 chapters written by experts from across the United States. The first section of the book focuses on overarching policy and management topics associated with vertebrate invasive species; including biosecurity threats and risk assessment, policy and regulation, and the economics of their management. The second section provides in-depth reviews of noteworthy invasive mammals, birds, amphibians, and reptiles. After finishing this book, the reader should understand the complexity of managing invasive species, the unique challenges that each new species may present, and the steps forward that may decrease the impact of these species on the environment, human health, and the economy.

Chlorophyll a fluorescence is a tool for evaluating plant responses to stress conditions. Fluorescence can be used in plant phenotyping and breeding programs to monitor biotic and abiotic stresses including mineral deficiencies, soil salinity, and pathogenic diseases. Chlorophyll Fluorescence: Understanding Crop Performance - Basics and Applications reviews a diversity of instruments available for recording and analyzing different types of light signals from plants and addresses the use of chlorophyll a fluorescence in research on plants and other photosynthesizing organisms, such as algae and cyanobacteria. This book characterizes the phenomenon of chlorophyll a fluorescence, describes the methods for its measurement, and demonstrates - using selected examples - the applicability of these methods to research the response of the photosynthetic apparatus and plant tolerance to unfavorable environmental conditions. In addition, chapters cover a general background on photosynthesis, analysis of delayed fluorescence, and the pulse amplitude modulated (PAM) technique. The book is addressed to a wide range of professionals in photosynthesis research and scientists from other areas of plant sciences.

"...a number of chapters provide excellent summaries of the modern methods available for studying fungal ecology, along with those more traditional methods that are still extremely valuable...overall it is a hugely valuable compendium of fungal ecology research. It is a must for the library shelf." -Lynne Boddy, Cardiff University, UK, Mycological Research, 2006 "These 44 chapters are an excellent starting point for anyone interested in fungal communities, in the broadest sense of the term. It is a book for dipping into...may be the last comprehensive treatment of fungal communities before the molecular revolution." -Meriel Jones, University of Liverpool, UK, Microbiology Today "... the scope of the work is tremendous. ... Excellent chapters providing overviews of methods ... provide a snap shot of the current approaches used to understand fungal communities at several levels of organization. This book should probably be on the shelf of every student of mycology, and many ecologists too. For all students, this book should be a valuable resource and source of inspiration." -Daniel Henk, Imperial College Faculty of Medicine, London, in Inoculum, Vol. 59, No. 3, May 2008 "Thorough taxonomic and subject indices further aid the reader in navigating through multiple authors' treatments of subjects of interest." - Anthony Amend, Department of Botany, University of Hawaii at Manoa in Economic Botany, V. 61 In all subjects in science, new findings and the use of new technologies allow us to develop an ever-greater understanding of our world. Expanded and updated coverage in the fourth edition includes: Adds new sections on Integrating Genomics and Metagenomics into Community Analysis, Recent Advances in Fungal Endophyte Research, Fungi in the Built Environment, and Fungal Signaling and Communication Includes a broader treatment of fungal communities in natural ecosystems with in-depth coverage of fungal adaptations to stress and conservation Expands coverage of the influence of climate change on fungi and the role of fungi in organically polluted ecosystems Includes contributions from scientists from 20 nations to illustrate a true global approach for bridging gaps between ecological concepts and mycology
