With millions of different bacterial species living in soil, the microbial community is extremely complex, varying at very small scales. Microbe-driven functions are essential for most processes in soil. Thus, a better understanding of this microbial diversity will be invaluable for the management of the various soil functions.

Nucleic Acids and Proteins in Soil combines traditional approaches in soil microbiology and biochemistry with the latest techniques in molecular microbial ecology. Included are methods to analyse the presence and importance of nucleic acids and proteins both inside and outside microbial cells, the horizontal gene transfer which drives bacterial diversity, as well as soil proteomes. Further chapters describe techniques such as PCR, fingerprinting, the challenging use of gene arrays for structural and functional analysis, stable isotope probing to identify in situ metabolic functions, and the use of marker and reporter genes in soil microbial ecology.

Modelling is an important tool for understanding the complexity of forest ecosystems and the variety of interactions of ecosystem components, processes and values. This book describes the hybrid approach to modelling forest ecosystems and their possible response to natural and management-induced disturbance. The book describes the FORECAST family of ecosystem management models at three different spatial scales (tree, stand and landscape), and compares them with alternative models at these three spatial scales. The book will help forest managers to understand what to expect from ecosystem-based forest models; serve as a tool for use in teaching about sustainability, scenario analysis and value trade-offs in natural resources management; and assist policy makers, managers and researches working in assessment of sustainable forest management and ecosystem management. Several real-life examples of using the FORECAST family of models in forest management and other applications are presented from countries including Canada, China, Spain and the USA, to illustrate the concepts described in the text. The book also demonstrates how these models can be extended for scenario and value trade-off analysis through visualization and educational or management games.

Landscape Research has been established as an interdisciplinary field dealing with complex environmental processes at multiple spatial and temporal scales. During the course of its history, various societal, technological and philosophical stimuli have shaped Landscape Research, e.g. the declaration of Landscape Ecology in the 1930s and contemporary global technological and societal developments.

Modern landscape research presently uses mathematics, statistics and advanced simulation techniques to combine empirical observations with known theories from ecology, physics, geography, social science and so on. Knowledge is thus updated and quantified via models that are used for estimation, hypothesis testing, prediction and assessment of scenarios. Advances in the computational sciences (e.g. fast computers and vast array of software), space science (e.g. remote sensing) and biological sciences (e.g. genetics) as well as new perspectives in the social sciences play important roles. Research findings are implemented in conservation management, urban planning and global change mitigation strategies.

This book identifies emerging fields and new challenges that are discussed within the framework of the driving forces of Landscape Development. Rather than offering a comprehensive overview of all fields of Landscape Research, the book addresses hot topics emphasizing major contemporary trends in these fields."

Human induced development activities are introduced with insufficient attention to their consequences for our living environment, even in cases where environmental assessments have been carried out. This apparent lack of attention to biodiversity in environmental assessment is rooted in the difficulties we have in adequately addressing biodiversity within the scope, time frame and budget allocated for assessments. This book provides a conceptual background and practical approaches to overcome these difficulties. It integrates the objectives of the Convention on Biological Diversity, its ecosystem approach, and the conceptual framework of the Millennium Ecosystem Assessment into a comprehensive approach to biodiversity in environmental assessment. It highlights the need to consider the value of biodiversity based on its use by each stakeholder, addresses the importance of both social and economic development to reach the Millennium Development Goals, and provides insights into ways to balance present and future needs.

Who Cares About Wildlife? integrates social science theory in order to provide a conceptual structure for understanding and studying human interaction with wildlife. A thorough review of the current literature in conceptual areas, including norms, values, attitudes, emotions, wildlife value orientations, cultural change, and evolutionary forces/inherited tendencies is provided, and the importance of these areas in studying human-wildlife relationships is highlighted. No other book both considers the human relationship with wildlife and provides a theoretical framework for understanding this relationship on the individual, as well as cultural level. Who Cares About Wildlife? will be valuable both to students and to practitioners in wildlife management and conservation, as well those interested in the human relationship with wildlife, natural resources, and the environment.

Agroecology theory is not endless. A point is reached where the central elements become visible, equations distill, and a conceptual apex is reached. This is agroecology condensed into core concepts and theorems describing how crops relate to each other, the land, and their surroundings. This book covers advanced agroecology, including agroecological theory as well as applications of biodiversity that underwrite agroecology. Since much of agroecology theory is new, the resulting algorithms are equally novel, though presented so as to be useful and appreciated by less mathematically inclined professionals.

Ecology of Fire-Dependent Ecosystems is brimming with intriguing ecological stories of how life has evolved with and diversified within the varied fire regimes that are experienced on earth. Moreover, the book places itself as a communication between students, fire scientists, and fire fighters, and each of these groups will find some familiar ground, and some challenging aspects in this text: something which ultimately will help to bring us closer together and enrich our different approaches to understanding and managing our changing planet. -- Sally Archibald, Professor, University of the Witwatersrand, Johannesburg, South Africa Most textbooks are as dry as kindling and about as much fun to sink your teeth into. This is not that kind of textbook. Devan Allen McGranahan and Carissa L. Wonkka have taken a complex topic and somehow managed to synthesize it into a comprehensive, yet digestible form. This is a book you can read cover to cover - I know, I did it. As a result, I took an enlightening journey through the history and fundamentals of fire and its role in the natural and human world, ending with a thoughtful review of the evolving relationship between humans and wildland fire. -- Chris Helzer, Nebraska Director of Science, The Nature Conservancy, and author of The Prairie Ecologist blog Ecology of Fire-Dependent Ecosystems: Wildland Fire Science, Policy, and Management is intended for use in upper-level courses in fire ecology and wildland fire management and as a reference for researchers, managers, and other professionals involved with wildland fire science, practice, and policy. The book helps guide students and scientists to design and conduct robust wildland fire research projects and critically interpret and apply fire science in any management, education, or policy situation. It emphasizes variability in wildland fire as an ecological regime and provides tools for students, researchers, and managers to assess and connect fire environment and fire behaviour to fire effects. Fire has not only shaped social and ecological communities but pushed ecosystems beyond previous boundaries, yet understanding the nature and effects of fire as an ecological disturbance has been slow, hampered by the complexity of the dynamic interactions between vegetation and climate and the fear of the destruction fire can bring. This book will help those who study, manage, and use wildland fire to develop new answers and novel solutions, based on an understanding of how fire functions in natural and social environments. It reviews literature, synthesizes concepts, and identifies research gaps and policy needs. The text also explores the interaction of fire and human culture, demonstrating how fire policy can be made adaptable to cultural and socio-ecological objectives.

While biodiversity loss is an ecological phenomenon, it also has further dimensions - political, social and, last but not least, economic. From the economic perspective, the rapid loss of biological diversity can be viewed in two ways. First, the consequence of this deterioration process is a loss of options and an increase in scarcity of the environmental 'good', biodiversity. Second, economic activity and the structure of global and local economic institutions have frequently been identified as the major drivers of biodiversity loss. In economic terms, this constitutes a market failure - market-based economic activities lead to processes which undermine the long-term stability of these very activities. This book provides an ecological economic perspective on the value of diversity in ecosystems. Combining insights from various sub-disciplines of ecology and environmental/ecological economics, the author constructs a conceptual framework which identifies the ways in which biodiversity influences human well-being and offers a novel, unifying perspective on the economic value of biodiversity. This framework demonstrates that biodiversity's economic value mainly results from uncertainty about the future, regarding both supply of and demand for ecosystem services, and interconnections between ecosystems. The book goes on to identify suitable methods for economic valuation of biodiversity and discusses the currently underdeveloped and underused approach of deliberative monetary valuation. Combining a strong theoretical framework with practical examples, this book will be of great interest to students and researchers of ecological economics, ecosystem services, environmental values and environmental and resource economics.

Throughout North America, non-native wild pigs have become an ecologically and economically destructive invasive species. Though they are regarded as a popular game species by some, provide economic benefits to others, and are even engrained into societal heritage in some areas, wild pigs are responsible for an extraordinary amount of damage in both natural and anthropogenic systems throughout North America. As the density and range of wild pig habitat have substantially increased over the last several decades, the magnitude and diversity of their negative impacts are not yet fully realized or quantified. With various conflicts continually emerging, wild pig management is difficult and expensive to achieve. As a result, wild pigs represent one of the greatest wildlife management challenges North America faces in the 21st century. Invasive Wild Pigs in North America: Ecology, Impacts, and Management addresses all aspects of wild pig biology, ecology, damage, and management in a single comprehensive volume. It assimilates and organizes information on the most destructive introduced vertebrate species in the United States, establishing a foundation from which managers, researchers, policy makers, and other stakeholders can build upon into the future. The book provides comprehensive coverage of wild pig biology and ecology, techniques for management and research, and regional chapters. It is an asset to readers interested in wild pigs, the resources they impact, and how to mitigate those impacts, and establishes a vision of the future of wild pigs in North America. Features: Compiles valuable knowledge for a broad audience including wild pig managers, researchers, adversaries, and enthusiasts from across North America Addresses taxonomy, morphology, genetics, physiology, spatial ecology, population dynamics, diseases and parasites, and the naturalized niche of wild pigs Includes chapters on damage to resources, management, research methods, human dimensions and education, and policy and legislation Contains full color images and case studies of interesting and informative situations being created by wild pigs throughout North America Includes a chapter on wild pigs at the wildland-urban interface, a more recent and especially challenging issue

This book comprehensively addresses the economic, social and institutional difficulties in conserving biodiversity and the ecosystem services that it provides.

It also covers the application of environmental economics and institutional economics to different cases and the use of techniques such as contingent valuation method and game theory. The book spans the globe with case studies drawn from a cross section of regions and continents including the UK, US, Europe, Australia, India, Africa and South America.

This practical handbook describes sampling and laboratory assessment methods for the biodiversity of a number of key functional groups of soil organisms, including insects, earthworms, nematodes, fungi and bacteria. The methods have been assembled and the protocols drafted by a number of scientists associated with the UNEP-GEF funded Conservation and Sustainable Management of Below-Ground Biodiversity project, executed by the Tropical Soil Biodiversity and Fertility (TSBF) institute of the International Center for Tropical Agriculture (CIAT). The methods provide a standardized basis for characterizing soil biodiversity occurring in terrestrial natural and agro-ecosystems in the tropics and current land uses in forest and forest margin areas. The aim is to assess soil biodiversity against current and historic land use practices both at plot and landscape scales and further to identify opportunities for improved sustainable land management through the introduction and/or management of soil biota, thus reducing the need for external inputs such as fertilizers and pesticides. The book does not contain identification keys as such, but there is extensive advice on the handling of specimens and the allocation of organisms to strain or functional group type.Published with TSBF-CIAT.

Key Features: Provides clear and authoritative recommendations for managing fire in ecological and social contexts Authors are all international leaders in their fields and include not only academics but also leaders of Indigenous communities Explains Indigenous cultural and knowledge systems to a degree that has rarely been accessible to lay and academic readers outside specialized disciplines like Anthropology Responds to growing need for new approaches to managing human-ecological systems that are in greater sympathy with Australia's natural environments/climate, and value the knowledge of Indigenous people Timely for scholarly and interest groups intervention, as the Australian government is again looking to 'develop the north' Sustainable Land Sector Development in Northern Australia sets out a vision for developing North Australia based on a culturally appropriate and ecologically sustainable land sector economy. This vision supports both Indigenous cultural responsibilities and aspirations, as well as enhancing enterprise opportunities for society as a whole. In the past, well-meaning if often misguided policy agendas have failed - and continue to fail - North Australians. This book helps breach that gap by acknowledging and harnessing Indigenous cultural strengths and knowledge systems for looking after the country and its people, as part of a smart, novel and diversified ecosystem services economy.

This book begins with a brief account of the extraordinary sequence of events that led to emergence of grasslands as major vegetation formations that now occupy some of the driest and hottest and the highest and coldest on earth as well as vast steppes and prairies in more temperate climes. It is the story of grasses successfully competing with forests and woodlands, aided and abetted by grazing herbivores and by humans and their use of fire as a tool. It is a story of adaptation to changing climates and the changing biophysical environments. A major focus of the book is the Palaearctic biogeographic realm that extends over some 45 million km(2) and thus more than 1/3 of the terrestrial ice-free surface on Earth. It comprises extensive grasslands of different types and origin, which can be subdivided into (1) natural grasslands with (1a) steppes (climatogenic in dry climates), (1b) arctic-alpine grasslands (climatogenic in cold climates) and (1c) azonal and extrazonal grasslands (pedogenic and topogenic) as well as (2) secondary grasslands created and sustained by human activities, such as livestock grazing, mowing or burning. Grasslands of the Palaearctic do not only form a major basis for the agriculture of the region and thus its food supply, but are also crucial for other ecosystem services and host a supra proportional part of the realm's plant and animal diversity. To reflect that suitability of grasslands for biodiversity strongly depends on their state, we apply the term High Nature Value grassland to those natural grasslands that are not degraded (in good state) and those secondary grasslands that are not intensified (semi-natural). The situation in a variety of countries where grasslands are evolving under the influence of global climate change is also considered. Case studies are presented on Southern Africa, Eastern Africa, India, China, South America, North America and Australia. The concluding chapter examines a set of themes arising from the chapters that make up the bulk of this book. The following provide a focus: recent history of grassland biomes - brief recap of current thinking and recent trends with special reference to dry grasslands in the Palearctic regions; the current status of grasslands and germplasm resources (biodiversity) - an overview; management systems that ensure sustainability; how to recover degraded grasslands; socio-economic issues and considerations in grassland management; the impacts of environmental problems in grasslands such as future climate change and intensification and the problems/prospects facing pastoralists and other grassland-based livestock producers.

Coral reefs are an important tourism resource for many coastal and island destinations and generate a range of benefits to their local communities, including as a food source, income from tourism, employment and recreational opportunities. However, coral reefs are under increasing threat from climate change and related impacts such as coral bleaching and ocean acidification. Other anthropogenic stresses include over-fishing, anchor damage, coastal development, agricultural run-off, sedimentation and coral mining. This book adopts a multidisciplinary approach to review these issues as they relate to the sustainable management of coral reef tourism destinations. It incorporates coral reef science, management, conservation and tourism perspectives and takes a global perspective of coral reef tourism issues covering many of the world's most significant coral reef destinations. These include the Great Barrier Reef and Ningaloo Reef in Australia, the Red Sea, Pacific Islands, South East Asia, the Maldives, the Caribbean islands, Florida Keys and Brazil. Specific issues addressed include climate change, pollution threats, fishing, island tourism, scuba diving, marine wildlife, governance, sustainability, conservation and community resilience. The book also issues a call for more thoughtful development of coral reef experiences where the ecological needs of coral reefs are placed ahead of the economic desires of the tourism industry.

The devastating impacts of natural disasters not only directly affect humans and infrastructure, but also animals, which may be crucial to the livelihoods of many people. This book considers the needs of animals in the aftermath of disasters and explains the importance of looking to their welfare in extreme events. The authors explore how animals are affected by specific disaster types, what their emergency and subsequent welfare needs are and the appropriate interventions. They describe the key benefits of management of animals to populations and discuss preventative measures that can be taken to reduce risk and build resilience. They also include a summary of recent debates and public policy advances on animals in disasters. The book covers livestock, companion and wild animals, with case studies to show how the concepts can be put into practice. It provides a standalone text for students of disaster studies and management as well as professionals and NGOs who require an entry-level introduction to the subject.

Sustainable intensification (SI) has emerged in recent years as a powerful new conceptualisation of agricultural sustainability and has been widely adopted in policy circles and debates. It is defined as a process or system where yields are increased without adverse environmental impact and without the cultivation of more land. Co-written by Jules Pretty, one of the pioneers of the concept and internationally known and respected authority on sustainable agriculture, this book sets out current thinking and debates around sustainable agriculture and intensification. It recognises that world population is increasing rapidly, so that yields must increase on finite land and other resources to maintain food security. It provides the first widely accessible overview of the concept of SI as an innovative approach to agriculture and as a key element in the transition to a green economy. It presents evidence from around the world to show how various innovations are improving yields, resilience and farm incomes, particularly for 'resource constrained' smallholders in developing countries, but also in the developed world. It shows how SI is a fundamental departure from previous models of agricultural intensification. It also highlights the particular role and potential of small-scale farmers and the fundamental importance of social and human capital in designing and spreading effective innovations.

Animals are a major link between the water column (pelagic) and the bottom (benthic) habitats in most shallow systems. This coupling is dominated by active processes such as suspension-feeding in which the organism actively uses energy to pump water that is then filtered to remove suspended particles that are consumed while undigested remains are deposited on the bottom. As a result of this feeding on and metabolism of particles, the animals excrete dissolved inorganic and organic waste back into the water column, and thus, become major components in the cycling and feedback of essential elements. With relatively high weight specific filtration rates of 1- 10 liters/hour/gram dry tissue and a propensity to form large aggregated populations (beds, reefs, schools and swarms), these organisms can play an important role in regulating water column processes Although estuarine bivalve molluscs such as oysters and mussels dominate the suspension-feeder literature, other groups including plankton and nekton that are found in estuarine as well as other aquatic systems are also potentially important removers of suspended particles. Thus, a significant part of the NATO Advanced Research Workshop focused on suspension-feeders as controllers of plankton abundance, biomass and diversity, system metabolism, nutrient cycling and scale dependency. Systems dominated by suspension-feeders are typically impacted by human activities including recreation, aquaculture, human and industrial pollution, and bilge water from shipping. Suspension-feeders are often impacted by fisheries and over-exploitation. These impacts commonly result in changes in ecosystem structure either through the food chain concentration of harmful substances or diseases, the introduction of alien species of suspension-feeders, or the instability of suspension-feeders systems through species displacement or phase shifts in the dominance between different suspension-feeding components such as nekton or zooplankton. These issues were addressed near the close of the workshop along with conclusions and syntheses developed by the working groups.
