Book Description
Often the meanings of words are changed subtly for interesting reasons. The implication of the word 'community' has changed from including all the organisms in an area to only those species at a particular trophic level (and often a taxonomically restricted group), for example, 'bird-community'. If this observation is correct, its probable cause is the dramatic growth in our knowledge of the ecological patterns along trophic levels (I call these horizontal patterns) and the processes that generate them. This book deals with vertical patterns - those across trophic levels -and tries to compensate for their relative neglect. In cataloging a dozen vertical patterns I hope to convince the reader that species interactions across trophic levels are as patterned as those along trophic levels and demand explanations equally forcefully. But this is not the only objective. A limited number of processes shape the patterns of species interaction; to demonstrate their existence is an essential step in understanding why ecosystems are the way they are. To achieve these aims I must resort to both mathematical techniques to develop theories and statistical techniques to decide between rival hypotheses. The level of mathematics is likely to offend nearly everyone. Some will find any mathematics too much, while others will consider the material to be old, familiar ground and probably explained with a poor regard for rigour and generality.

Book Description
This novel book bridges the gap between the energetic and species approaches to studying food webs, addressing many important topics in ecology. Species, matter, and energy are common features of all ecological systems. Through the lens of complex adaptive systems thinking, the authors explore how the inextricable relationship between species, matter, and energy can explain how systems are structured and how they persist in real and model systems. Food webs are viewed as open and dynamic systems. The central theme of the book is that the basis of ecosystem persistence and stability rests on the interplay between the rates of input of energy into the system from living and dead sources, and the patterns in utilization of energy that result from the trophic interactions among species within the system. To develop this theme, the authors integrate the latest work on community dynamics, ecosystem energetics, and stability. In so doing, they present a unified ecology that dispels the categorization of the field into the separate subdisciplines of population, community, and ecosystem ecology. Energetic Food Webs is suitable for both graduate level students and professional researchers in the general field of ecology. It will be of particular relevance and use to those working in the specific areas of food webs, species dynamics, material and energy cycling, as well as community and ecosystem ecology.

Book Description
Dynamic Food Webs challenges us to rethink what factors may determine ecological and evolutionary pathways of food web development. It touches upon the intriguing idea that trophic interactions drive patterns and dynamics at different levels of biological organization: dynamics in species composition, dynamics in population life-history parameters and abundances, and dynamics in individual growth, size and behavior. These dynamics are shown to be strongly interrelated governing food web structure and stability and the role of populations and communities play in ecosystem functioning. Dynamic Food Webs not only offers over 100 illustrations, but also contains 8 riveting sections devoted to an understanding of how to manage the effects of environmental change, the protection of biological diversity and the sustainable use of natural resources. Dynamic Food Webs is a volume in the Theoretical Ecology series. Relates dynamics on different levels of biological organization: individuals, populations, and communities Deals with empirical and theoretical approaches Discusses the role of community food webs in ecosystem functioning Proposes methods to assess the effects of environmental change on the structure of biological communities and ecosystem functioning Offers an analyses of the relationship between complexity and stability in food webs

Book Description
Biologists have made significant advances in our understanding of the Earth's shallow subtidal marine ecosystems, but the findings on these disparate regions have never before been documented and gathered in a single volume. Now, in Food Webs and the Dynamics of Marine Reefs, Tim R. McClanahan and George M. Branch fill this lacuna with a comparative and comprehensive collection of nine essays written by experts on specific aquatic regions. Each essay focuses on the food webs of a respective ecosystem and the factors affecting these communities, from the intense and direct pressure of human influence on fisheries to the multi-vector contributors to climate change. The book covers nine shallow water marine ecosystems from selected areas throughout the world: four coral reef systems, three hard bottom systems, and two kelp systems. In summarizing their organization, human influence on them, and recent developments in these ecosystems, the authors contribute to our understanding of their ecological organization and management. Food Webs and the Dynamics of Marine Reefs will be a useful tool for all benthic marine investigators, providing an expert, comparative view of these aquatic regions.

Book Description
Food webs are diagrams depicting which species interact or in other words, who eats whom. An understanding of the structure and function of food webs is crucial for any study of how an ecosystem works, including attempts to predict which communities might be more vulnerable to disturbance and therefore in more immediate need of conservation. Although it was first published twenty years ago, Stuart Pimm's Food Webs remains the clearest introduction to the study of food webs. Reviewing various hypotheses in the light of theoretical and empirical evidence, Pimm shows that even the most complex food webs follow certain patterns and that those patterns are shaped by a limited number of biological processes, such as population dynamics and energy flow. Pimm provides a variety of mathematical tools for unravelling these patterns and processes, and demonstrates their application through concrete examples. For this edition, he has written a new foreword covering recent developments in the study of food webs and demonstrates their continuing importance to conservation biology.

Book Description
This volume focuses on new trends in monitoring biodiversity in the Asia-Pacific region, one of the most rapidly changing areas in the world. It provides reviews of the challenges in studying the spatial variability of biodiversity across various ecosystems. This book also describes newly developed concepts and methods for biodiversity observation including ubiquitous genotyping, systematic conservation, monitoring of the functions and services of ecosystems and biodiversity informatics. These contributions will lead to establishing integrative observations and assessments of biodiversity, essential for reporting the current status and for the effective conservation and sustainable use of biodiversity. This work will interest biodiversity researchers not only in the Asia-Pacific region but also across the entire globe.
