Available in PDF, EPUB and Kindle. Book excerpt: Kerr and Dickie propose the development of a new ecological theory, one that can lead to a more effective remedy for the drastic effects of heavy fishing on natural communities of organisms in both marine and freshwater environments. By plotting the densities of the biomass of all organisms in a given community by body-size classes, the authors provide empirical evidence of what they term "the biomass body-size spectrum" in the world's oceans. After examining this evidence, they propose an underlying theory of predator-prey energy transfer: larger species eat smaller species, providing energy exchange across all species within an ecosystem. Providing the first comprehensive synthesis of the energy flow within the biomass spectrum, this book demonstrates not only a new understanding of the self-organizing properties of ecological production systems but also the potential of the biomass spectrum methodology for offering practical remedies when these natural systems are exploited by humans.

Available in PDF, EPUB and Kindle. Book excerpt: Fish are one of the most important global food sources, supplying a significant share of the world’s protein consumption. From stocks of wild Alaskan salmon and North Sea cod to entire fish communities with myriad species, fisheries require careful management to ensure that stocks remain productive, and mathematical models are essential tools for doing so. Fish Ecology, Evolution, and Exploitation is an authoritative introduction to the modern size- and trait-based approach to fish populations and communities. Ken Andersen covers the theoretical foundations, mathematical formulations, and real-world applications of this powerful new modeling method, which is grounded in the latest ecological theory and population biology. He begins with fundamental assumptions on the level of individuals and goes on to cover population demography and fisheries impact assessments. He shows how size- and trait-based models shed new light on familiar fisheries concepts such as maximum sustainable yield and fisheries selectivity—insights that classic age-based theory can’t provide—and develops novel evolutionary impacts of fishing. Andersen extends the theory to entire fish communities and uses it to support the ecosystem approach to fisheries management, and forges critical links between trait-based methods and evolutionary ecology. Accessible to ecologists with a basic quantitative background, this incisive book unifies the thinking in ecology and fisheries science and is an indispensable reference for anyone seeking to apply size- and trait-based models to fish demography, fisheries impact assessments, and fish evolutionary ecology.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive introduction to ocean ecology and a new way of thinking about ocean life Marine ecology is more interdisciplinary, broader in scope, and more intimately linked to human activities than ever before. Ocean Ecology provides advanced undergraduates, graduate students, and practitioners with an integrated approach to marine ecology that reflects these new scientific realities, and prepares students for the challenges of studying and managing the ocean as a complex adaptive system. This authoritative and accessible textbook advances a framework based on interactions among four major features of marine ecosystems—geomorphology, the abiotic environment, biodiversity, and biogeochemistry—and shows how life is a driver of environmental conditions and dynamics. Ocean Ecology explains the ecological processes that link organismal to ecosystem scales and that shape the major types of ocean ecosystems, historically and in today's Anthropocene world. Provides an integrated new approach to understanding and managing the ocean Shows how biological diversity is the heart of functioning ecosystems Spans genes to earth systems, surface to seafloor, and estuary to ocean gyre Links species composition, trait distribution, and other ecological structures to the functioning of ecosystems Explains how fishing, fossil fuel combustion, industrial fertilizer use, and other human impacts are transforming the Anthropocene ocean An essential textbook for students and an invaluable resource for practitioners

Available in PDF, EPUB and Kindle. Book excerpt: Sustainable sources of energy and a supply of good quality water are two major challenges facing modern societies across the globe. Biomass from cultivated plants may be used to generate energy, but at the cost of contaminated surface waters from pesticide and fertiliser use. This two-volume set examines the potential use of biomass as both a source of sustainable energy and a resource to tackle contaminated soils and wastewaters. Consideration is given to non-food crops, bacteria ,and fungi as sources of biomass and the book enables the reader to identify the best local bioresources according to the desired application. With contributions from across the globe, this is an essential guide to meeting the demand for energy and pollution remediation by exploiting local and renewable resources. The example scenarios given may inspire policy makers and local officers, while chemical engineers and environmental scientists in both academia and industry will benefit from the comprehensive review of current thinking and application.

This book was released on 1986 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The text is intended as supplementary reading for fisheries workers, especially in developing countries, who do not always have ready access to current literature on applied marine ecology. An attempt is made to develop a wide range of concepts in a form that will hopefully encourage their incorporation into a practical, decision-making context. The food web and associated trophic interactions form the principal theme, in an approach that gives equal emphasis to qualitative, as well as the less easily measured quantitative considerations. An attempt is made to illustrate the consequences of the aggregated nature of much of marine production, as well as the subsequent dispersal of production in space and time, and how these processes affect the potential for economic harvest of commercial components of the ecosystem. Separate sections touch on environmental influences on production, relevant spatial and temporal scales for ecosystem analysis, life history strategies, diversity and stability, the concepts of the ecological niche, the community and the assemblage, and outline some first steps towards quantifiying production in marine ecosystems. Different approaches to representing trophic and other interactions are discussed, with examples from the literature. Reference is made to several ecological subsystems, in order to illustrate the main concepts presented. These include the mangrove ecosystem, the arcto-boreal macrophyte community, a mediterranean demersal fish assemblage, and the oceanic ecosystem associated with high seas tuna stocks. In practical terms, it is concluded that the first and simplest approach to multispecies resource management is not necessarily the manipulation of individual food web components, but the identification, mapping and conservation of critical habitats, especially centres of local production, and their associated ecological dissipation structures.

Available in PDF, EPUB and Kindle. Book excerpt: Recent technological advances have enabled comprehensive determination of the molecular composition of living cells. The chemical interactions between many of these molecules are known, giving rise to genome-scale reconstructed biochemical reaction networks underlying cellular functions. Mathematical descriptions of the totality of these chemical interactions lead to genome-scale models that allow the computation of physiological functions. Reflecting these recent developments, this textbook explains how such quantitative and computable genotype-phenotype relationships are built using a genome-wide basis of information about the gene portfolio of a target organism. It describes how biological knowledge is assembled to reconstruct biochemical reaction networks, the formulation of computational models of biological functions, and how these models can be used to address key biological questions and enable predictive biology. Developed through extensive classroom use, the book is designed to provide students with a solid conceptual framework and an invaluable set of modeling tools and computational approaches.
