Enclosed ecosystem experiments have gained in popularity as research tools in ecological science, particularly in the study of coastal aquatic environments. These systems provide scientists with a degree of experimental control that is not achievable through field experiments. Yet to date, techniques for systematically extrapolating results from small-scale experimental ecosystems to larger, deeper, more open, more biologically diverse, and more heterogeneous ecosystems in nature have not been well developed. Likewise, researchers have lacked methods for comparing and extrapolating information among natural ecosystems that differ in scale.

Enclosed Experimental Ecosystems and Scale: Tools for Understanding and Managing Coastal Ecosystems provides scientists, managers, and policy makers with an introduction to what has been termed the "problem of scale," and presents information that will allow for improved design and interpretation of enclosed experimental aquatic ecosystems. The book integrates the results of a 10-year research project involving a multi-disciplinary team of scientists and students to explore scale-related questions in a variety of coastal habitats. Anticipating use as a reference, the book has been designed so that individual sections and individual pages can function as stand alone units.

Experimental ecosystems represent a potentially powerful tool for testing and expanding our understanding of the mechanisms that drive ecological dynamics in the coastal zone. The information contained within the pages of this book is intended to help practitioners make the most of this promising approach to ecological research.

Metabolic Ecology - A Scaling Approach (Hardcover): Richard M. Sibly, James H. Brown, Astrid Kodric-Brown Metabolic Ecology - A Scaling Approach (Hardcover)
Richard M. Sibly, James H. Brown, Astrid Kodric-Brown
R3,141 R2,207 Discovery Miles 22 070 Save R934 (30%) Shipped within 7 - 13 working days

One of the first textbooks in this emerging important field of ecology.Most of ecology is about metabolism: the ways that organisms use energy and materials. The energy requirements of individuals - their metabolic rates - vary predictably with their body size and temperature. Ecological interactions are exchanges of energy and materials between organisms and their environments. So metabolic rate affects ecological processes at all levels: individuals, populations, communities and ecosystems. Each chapter focuses on a different process, level of organization, or kind of organism. It lays a conceptual foundation and presents empirical examples. Together, the chapters provide an integrated framework that holds the promise for a unified theory of ecology.

The book is intended to be accessible to upper-level undergraduate, and graduate students, but also of interest to senior scientists. Its easy-to-read chapters and clear illustrations can be used in lecture and seminar courses. Together they make for an authoritative treatment that will inspire future generations to study metabolic ecology.

Tropical Forest Conservation and Industry Partnership - An Experience from the Congo Basin (Hardcover): Connie J. Clark, John... Tropical Forest Conservation and Industry Partnership - An Experience from the Congo Basin (Hardcover)

Historically, the conservation of forests and wildlife has focused on the creation of national parks and reserves. However, only 9% of protected areas are larger than 14,000 hectares, likely making them too small to conserve ecosystem services and prevent loss of wide-ranging keystone species such as elephant and leopard. New approaches are needed that extend conservation beyond protected area boundaries into areas where economic considerations prevail.

The book describes one such emerging model of conservation: the integration of the private sector into partnerships to protect biodiversity and improve forest management. While such partnerships are being created in nearly every sector of resource extraction, detailed analyses of how such partnerships work and whether they benefit biodiversity conservation are rare. Using a case study from the Congo Basin, the book examines principles of conservation and partnership, and provides technical and methodological details to replicate an innovative conservation model. It presents concrete solutions for expanding conservation across multi-use landscapes, a necessary action as industry expands to all the corners of the globe.

Fungal nanotechnology has great prospects for developing new products with industrial, agricultural, medicinal, and consumer applications in a wide range of sectors. The fields of chemical engineering, agri-food, biochemistry, pharmaceuticals, diagnostics, and medical device development all employ fungal products, with fungal nanomaterials currently used in applications ranging from drug development to the food industry and agricultural biotechnology. Fungal agents are an environmentally friendly, clean, non-toxic agent for the synthesis of metal nanoparticles and employ both intracellular and extracellular methods. The simplicity of scaling up and downstream processing and the presence of fungal mycelia which afford an increased surface area provide key advantages. In addition, the large spectrum of synthesized nanoparticle morphologies and the substantially faster biosynthesis rate in cell-free filtrate (due to the higher amount of proteins secreted in fungi) make this a particularly enticing route. Understanding the diversity of fungi in assorted ecosystems, as well as their interactions with other microorganisms, animals, and plants, underpins real and innovative technological developments and the applications of metal nanoparticles in many disciplines including agriculture, catalysis, and biomedical biosensors. Importantly, biogenic fungal nanoparticles show significant synergistic characteristics when combined with antibiotics and fungicides to offer substantially greater resistance to microbial growth and applications in nanomedicine ranging from topical ointments and bandages for wound healing to coated stents.

This textbook offers a detailed overview of the current state of knowledge concerning the ecology and management of compositionally and structurally diverse forests. It provides answers to central questions such as: What are the scientific concepts used to assess the growth, dynamics and functioning of mixed-species forests, how generalizable are they, and what kind of experiments are necessary to develop them further? How do mixed-species stands compare with monocultures in relation to productivity, wood quality, and ecological stability in the face of stress and disturbances? How are the effects of species mixtures on ecosystem functioning influenced by the particular species composition, site conditions, and stand structure? How does any over- or underyielding at the forest-stand level emerge from the tree and organ level, and what are the main mechanisms behind mixing effects? How can our current scientific understanding of mixed-species forests be integrated into silvicultural concepts as well as practical forest management and planning? Do the ecological characteristics of mixed-species stands also translate into economic differences between mixtures and monocultures? In addition, the book addresses experimental designs and analytical approaches to study mixed-species forests and provides extensive empirical information, general concepts, models, and management approaches for mixed-species forests. As such, it offers a valuable resource for students, scientists and educators, as well as professional forest planners, managers, and consultants.

R3,471 Discovery Miles 34 710 Shipped within 7 - 12 working days

The earth, our home, is in crisis. There are two sides to this crisis-our global economy, and its effect on the ecology of our home planet. Despite conventional thinking that typical monetary and fiscal manipulations will put us back on the path of economic growth, the reality is not that simple. Meanwhile, the natural environment is sending unmistakable warnings. Glaciers are melting; oceans are becoming dangerously acidic; species and their ecological services are becoming extinct; and weather patterns are becoming increasingly severe and unpredictable each year. The stress on resource systems of all kinds threatens to shrink the carrying capacity of the planet, even as we call upon it for increased contributions to support a burgeoning human population. Co-written by an ecologist and an economist, Economics and Ecology: United for a Sustainable World counsels the replacement of symptomatic thinking with a systemic worldview that treats the environment and the economy as an ecosystemic unit. The first part of the book establishes the methodological and biophysical principles needed to develop the concept of socioeconomic sustainability. The second part of the book examines the misuse of economics in the service of what increasingly appears to be a ruinous pursuit of material wealth and expansion. The third part offers advice on reconciling economics and ecology by proposing an economics in which the principles employed are aligned with the biophysical principles of ecology. This timely volume puts forth a sustainable worldview based on systemic thinking, with the emphasis more on what and how people think than on what they do. A unique reference for professionals and laypersons alike, it can also serve as a supplementary classroom text for students of economics, ecology, biology, and environmental science.

The first stand-alone textbook for at least ten years on this increasingly hot topic in times of global climate change and sustainability in ecosystems. Ecological biochemistry refers to the interaction of organisms with their abiotic environment and other organisms by chemical means. Biotic and abiotic factors determine the biochemical flexibility of organisms, which otherwise easily adapt to environmental changes by altering their metabolism. Sessile plants, in particular, have evolved intricate biochemical response mechanisms to fit into a changing environment. This book covers the chemistry behind these interactions, bottom up from the atomic to the system's level. An introductory part explains the physico-chemical basis and biochemical roots of living cells, leading to secondary metabolites as crucial bridges between organisms and the respective ecosystem. The focus then shifts to the biochemical interactions of plants, fungi and bacteria within terrestrial and aquatic ecosystems with the aim of linking biochemical insights to ecological research, also in human-influenced habitats. A section is devoted to methodology, which allows network-based analyses of molecular processes underlying systems phenomena. A companion website offering an extended version of the introductory chapter on Basic Biochemical Roots is available at http://www.wiley.com/go/Krauss/Nies/EcologicalBiochemistry

This is the first coherent description of all levels of communication of ciliates. Ciliates are highly sensitive organisms that actively compete for environmental resources. They assess their surroundings, estimate how much energy they need for particular goals, and then realise the optimum variant. They take measures to control certain environmental resources. They perceive themselves and can distinguish between `self' and `non-self'. They process and evaluate information and then modify their behaviour accordingly. These highly diverse competences show us that this is possible owing to sign(aling)-mediated communication processes within ciliates (intra-organismic), between the same, related and different ciliate species (inter-organismic), and between ciliates and non-ciliate organisms (trans-organismic). This is crucial in coordinating growth and development, shape and dynamics. This book further serves as a learning tool for research aspects in biocommunication in ciliates. It will guide scientists in further investigations on ciliate behavior, how they mediate signaling processes between themselves and the environment.

All organisms live in clusters, but such fractured local populations, or demes, nonetheless maintain connectivity with one another by some amount of gene flow between them. Most such metapopulations occur naturally, like clusters of amphibians in vernal ponds or baboon troops spread across the African veldt. Others have been created as human activities fragment natural landscapes, as in stands of trees separated by roads. As landscape change has accelerated, understanding how these metapopulations function-and specifically how they adapt-has become crucial to ecology and to our very understanding of evolution itself. With Adaptation in Metapopulations, Michael J. Wade explores a key component of this new understanding of evolution: interaction. Synthesizing decades of work in the lab and in the field in a book both empirically grounded and underpinned by a strong conceptual framework, Wade looks at the role of interaction across scales from gene selection to selection at the level of individuals, kin, and groups. In so doing, he integrates molecular and organismal biology to reveal the true complexities of evolutionary dynamics from genes to metapopulations.

Since its discovery Antarctica has held a deep fascination for biologists. Extreme environmental conditions, seasonality and isolation have lead to some of the most striking examples of natural selection and adaptation on Earth. Paradoxically, some of these adaptations may pose constraints on the ability of the Antarctic biota to respond to climate change. Parts of Antarctica are showing some of the largest changes in temperature and other environmental conditions in the world. In this volume, published in association with the Royal Society, leading polar scientists present a synthesis of the latest research on the biological systems in Antarctica, covering organisms from microbes to vertebrate higher predators. This book comes at a time when new technologies and approaches allow the implications of climate change and other direct human impacts on Antarctica to be viewed at a range of scales; across entire regions, whole ecosystems and down to the level of species and variation within their genomes. Chapters address both Antarctic terrestrial and marine ecosystems, and the scientific and management challenges of the future are explored.

R3,501 Discovery Miles 35 010 Shipped within 7 - 12 working days

Fascinating and diverse, savanna ecosystems support a combination of pastoral and agropastoral communities alongside wild and domestic herbivores that can be found nowhere else. This diversity has made the study of these areas problematic. Ecosystem Function in Savannas: Measurement and Modeling at Landscape to Global Scales addresses some of the discontinuities in the treatment of savannas by the scientific community and documents a range of measurements, methods, technologies, applications, and modeling approaches. Based on contributions from leading authorities and experts on savanna systems worldwide, the book describes the global savanna biome in terms of its broad ecological properties, temporal dynamics, disturbance levels, and human dimensions. The text examines carbon, water, energy, and trace gas fluxes for major global savanna regions. It looks at quantitative surface properties of savannas that can be retrieved using remote sensing and numerical approaches used to explore savanna dynamics. The authors also discuss how savanna modeling and measurement approaches might be unified. By presenting this confluence of information in a single resource, the book provides a platform for examining synergies, connections, integrative opportunities, and complementarities among approaches and data sources. This information can then be used to harmonize measurement and modeling methods among scales and across disciplinary boundaries. The book builds a bridge across the markedly different perspectives on savannas by which ecologists, biogeochemists, remote sensors, geographers, anthropologists, and modelers approach their science.

This book discusses the dynamics and resource management qualities of the peri-urban interface to address climate change consequences, focusing on the peri-urban region of the global city of Bengalaru. In 5 chapters, the authors document the unique challenges experienced in peri-urban areas, including soil-water vegetation dynamics, local and regional impacts on water bodies (surface and groundwater), food production issues, and the inhibited adaptive capacity of local communities. The book also provides knowledge on implementations of environmental management by local institutions, government interventions that have acted as catalysts in promoting community based adaptation strategies, and the physical, social and economic aspects of rural-urban dynamics. The book not only adds to the scarce existing literature on peri-urban contexts, but also addresses the role of culture in protecting ecological landscapes and how traditions play an important role in coping with climate change. Furthermore, the authors expand on these climate change coping mechanisms in peri-urban areas, taking into account local cultural factors and interesting governance interventions in the context of health. The book will be of interest to planners, policy makers, and students and researchers engaged in rural-urban dynamics and climate change adaptation.
