This book offers an environmental-economic analysis of exploited ecosystems with a clear policy orientation. The study moves beyond traditional economic fishery analysis in two respects. First, several theoretical and numerical models are offered that combine economic and ecological descriptions of fisheries. Second, valuation and stakeholder concerns are addressed in empirical analyses employing both qualitative and quantitative approaches. The approaches, models and policy insights are sufficiently general and innovative to interest a broad audience.
This is a readable, informative and up-to-date account of the patterns and controls on biodiversity. The author describes major trends in species richness, along with uncertainties in current knowledge. The various possible explanations for past and present species patterns are discussed and explained in an even-handed and accessible way. The implications of global climate change and habitat loss are considered, along with current strategies for preserving what we have. This book examines the state of current understanding of species richness patterns and their explanations. As well as the present day world, it deals with diversification and extinction, in the conservation of species richness, and the difficulties of assessing how many species remain to be discovered. The scientifically compelling subject of vegetation-climate interaction is considered in depth. Written in an accessible style, the author offers an up-to-date, rigorous and yet eminently comprehensible overview of the ecology and biogeography of species richness. He departs from the often heavy approach of earlier texts, without sacrificing rigor and depth of information and analysis. Prefacing with the aims of the book, Chapter 1 opens with an explanation of latitudinal gradients, including a description of major features of the striking gradients in species richness, exceptions to the rule, explanations, major theories and field and experimental tests. The following chapter plumbs the depth of time, including the nature of the fossil record, broad timescale diversity patterns, ecosystem changes during mass extinctions and glaciations and their influence on species richness. Chapters 3 and 4 consider hotspots and local scale patterns in species richness while Chapter 5 looks at the limitations and uncertainties on current estimates of richness, the last frontiers of species diversity and the process of identifying new life forms. The last three chapters cover humans and extinctions in history and prehistory, current habitat and global change, including the greenhouse effect, and the race to preserve what we still have, including parks, gene banks and laws.
Population and evolutionary genetics have been quickly developing ?elds of biological research over the past decades. This book compiles our current understanding of genetic processes in natural populations. In addition, the book provides the author's original ideas and concepts based on the data obtained by himself and his close coworkers. The author introduces his pioneering concept of population genetic stability, and much of thebook is concerned with the factors and conditions of such stability. Why does genetic stability matter so much? Altukhov argues that the sustainable use of natural resources, including genetic resources of popu- tions, critically depends on the maintenance of their stability. The preser- tion of well-adapted genetic characteristics from one generation to the next is essential for this stability. Traditionally, population genetics has been - cusedonevolution andthe role of evolutionary factorsinshapinggenetic structures of populations. While the idea of a population as a dynamic unit of evolution has been widely accepted, the signi?cance of genetic stability and its implications for the long-term survival of populations and species have not been fully appreciated.
This book explores the epistemological and ethical issues at the foundations of environmental philosophy, emphasizing the conservation of biodiversity. Sahota Sarkar criticizes previous attempts to attribute intrinsic value to nature and defends an anthropocentric position on biodiversity conservation based on an untraditional concept of transformative value. Unlike other studies in the field of environmental philosophy, this book is as much concerned with epistemological issues as with environmental ethics. It covers a broad range of topics, including problems of explanation and prediction in traditional ecology and how individual-based models and Geographic Information Systems (GIS) technology is transforming ecology. Introducing a brief history of conservation biology, Sarkar analyzes the new consensus framework for conservation planning through adaptive management. He concludes with a discussion of the future directions for theoretical research in conservation biology and environmental philosophy.
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."
The diversity, ecological role and biotechnological applications of marine fungi have been addressed in numerous scientific publications in the last few years. This enormous spurt of information has led to a dire need among students and professionals alike for a source, which contains comprehensive reviews of various aspects of marine fungi. This book addresses this need, especially since it is written by reputed marine mycologists. The latest information on topics including molecular taxonomy and phylogeny, ecology of fungi in different marine habitats such as deep sea, corals, dead- sea, fungi in extreme marine environments and their biotechnological applications is reviewed. The book presents a comprehensive source of information and analysis aimed at marine fungi for researchers, teachers and students of marine mycology.
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.
The second edition of this widely cited textbook continues to provide a concise but comprehensive introduction to cave and subterranean biology, describing this fascinating habitat and its biodiversity. It covers a range of biological processes including ecosystem function, evolution and adaptation, community ecology, biogeography, and conservation. The authors draw on a global range of examples and case studies from both caves and non-cave subterranean habitats. One of the barriers to the study of subterranean biology has been the extraordinarily large number of specialized terms used by researchers; the authors explain these terms clearly and minimize the number that they use. This new edition retains the same 10 chapter structure of the original, but the content has been thoroughly revised and updated throughout to reflect the huge increase in publications concerning subterranean biology over the last decade.

This book comprehensively addresses the economic, social and institutional difficulties in conserving biodiversity and the ecosystem services that it provides. It covers a wide range of issues such as biodiversity, ecosystem services and valuation in the context of diverse ecosystems such as tropical forests, marine areas, wetlands and agricultural landscapes, non-timber forest products, incentives and institutions, payments for ecosystem services, governance, intellectual property rights and the protection of traditional knowledge, management of protected areas, and climate change and biodiversity. 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 book is unique in providing a global overview of alpine (high
mountain) habitats that occur above the natural (cold-limited) tree
line, describing the factors that have shaped them over both
ecological and evolutionary timescales. The broad geographic
coverage helps synthesize common features whilst revealing
differences in the world's major alpine systems from the Arctic to
the Tropics. The words "barren" and "wasteland" have often been
applied to describe landscapes beyond the tree line. However, a
closer look reveals a large diversity of habitats, assemblages and
individual taxa in the alpine zone, largely connected to
topographic diversity within individual alpine regions.
For years scientists viewed the deep sea as calm, quiet, and undisturbed, with marine species existing in an ecologically stable and uniform environment. Recent discoveries have completely transformed that understanding and the deep sea is recognized as a complicated and dynamic environment with a rich diversity of marine species. Carefully designed to provide practical information in an easily accessible format, Methods for the Study of Deep-Sea Sediments, Their Functioning, and Biodiversity covers how to investigate the biological components through analysis of their biodiversity. It also provides the protocols and methodological details needed to investigate some aspects of the functional biodiversity of variables commonly utilized to describe and understand the drivers of deep-sea ecosystem functioning. This volume contains detailed protocols for analyzing all benthic components from benthic viruses, prokaryotes, protozoa, foraminifera, to meio-, macro-, and megafauna. It includes step-by-step procedures, with additional notes on the crucial steps or possible difficulties arising from the analysis. Each chapter provides a brief introduction, a description of the sampling procedures and/or the sample treatment, and then the laboratory protocols, providing information on instrument setting and/or the solutions utilized. Each chapter also contains a visual scheme of the protocol for use during laboratory activities and for tracking each laboratory step. Linking information on biodiversity with the functioning of the marine ecosystems, the book covers all living components of the benthos. It provides practical information for anyone studying deep-sea habitats, their characteristics, functioning, and biodiversity.
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.
Introducing Biological Rhythms is a primer that serves to introduce individuals to the area of biological rhythms. It describes the major characteristics and discusses the implications and applications of these rhythms, while citing scientific results and references. Also, the primer includes essays that provide in-depth historic and other background information for those interested in more specific topics or concepts. It covers a basic cross-section of the field of chronobiology clearly enough so that it can be understood by a novice, or an undergraduate student, but that it would also be sufficiently technical and detailed for the scientist.
The relentless exploitation and unsustainable use of wildlife,
whether for food, medicine or other uses, is a key concern for
conservationists worldwide. Indeed, wildlife conservation and
sustainable use have recently become centrepieces in conservation
and development research. Assessment, interpretation and ultimate
action in a scientific study of exploited species must consider
numerous factors: from the biology, habitat requirements and
population dynamics of the species in question to the relationships
that people have with their environment and the species within it.
Any long-term management plan must ensure that people and wildlife
can coexist - otherwise it is doomed to failure.
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?

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.
Reduce the environmentally negative aspects of industrial
agriculture with an ecologically sound philosophy
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.
Through a global and interdisciplinary lens, this book discusses, analyzes and summarizes the novel conservation approach of rewilding. The volume introduces key rewilding definitions and initiatives, highlighting their similarities and differences. It reviews matches and mismatches between the current state of ecological knowledge and the stated aims of rewilding projects, and discusses the role of human action in rewilding initiatives. Collating current scholarship, the book also considers the merits and dangers of rewilding approaches, as well as the economic and socio-political realities of using rewilding as a conservation tool. Its interdisciplinary nature will appeal to a broad range of readers, from primary ecologists and conservation biologists to land managers, policy makers and conservation practitioners in NGOs and government departments. Written for a scientifically literate readership of academics, researchers, students, and managers, the book also acts as a key resource for advanced undergraduate and graduate courses.
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
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.
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. |
