Book Description
First published in 1972 and now available for the first time in paperback, this book is the summation of the life work of one of the most influential scientists of our time. Of permanent interest in this history and philosophy of science, it is also frequently cited in the current ecological literature and is still up-to-date in many categories. Written in MacArthur's beautifully lucid style this work will continue to be read by anyone concerned with biological ideas. *Lightning Print On Demand Title

Book Description
CONSERVATION BIOGEOGRAPHY The Earth’s ecosystems are in the midst of an unprecedented period of change as a result of human action. Many habitats have been completely destroyed or divided into tiny fragments, others have been transformed through the introduction of new species, or the extinction of native plants and animals, while anthropogenic climate change now threatens to completely redraw the geographic map of life on this planet. The urgent need to understand and prescribe solutions to this complicated and interlinked set of pressing conservation issues has lead to the transformation of the venerable academic discipline of biogeography – the study of the geographic distribution of animals and plants. The newly emerged sub-discipline of conservation biogeography uses the conceptual tools and methods of biogeography to address real world conservation problems and to provide predictions about the fate of key species and ecosystems over the next century. This book provides the first comprehensive review of the field in a series of closely interlinked chapters addressing the central issues within this exciting and important subject.

Book Description
Pioneered in the late 1980s, the concept of macroecology—a framework for studying ecological communities with a focus on patterns and processes—revolutionized the field. Although this approach has been applied mainly to terrestrial ecosystems, there is increasing interest in quantifying macroecological patterns in the sea and understanding the processes that generate them. Taking stock of the current work in the field and advocating a research agenda for the decades ahead, Marine Macroecology draws together insights and approaches from a diverse group of scientists to show how marine ecology can benefit from the adoption of macroecological approaches. Divided into three parts, Marine Macroecology first provides an overview of marine diversity patterns and offers case studies of specific habitats and taxonomic groups. In the second part, contributors focus on process-based explanations for marine ecological patterns. The third part presents new approaches to understanding processes driving the macroecolgical patterns in the sea. Uniting unique insights from different perspectives with the common goal of identifying and understanding large-scale biodiversity patterns, Marine Macroecology will inspire the next wave of marine ecologists to approach their research from a macroecological perspective.

Book Description
Issues of scale have become increasingly important to ecologists. This book addresses the structure of regional (large-scale) ecological assemblages or communities, and the influence this has at a local (small-scale) level. This macroecological perspective is essential for the broader study of ecology because the structure and function of local communities cannot be properly understood without reference to the region in which they are situated. The book reviews and synthesizes the issues of current importance in macroecology, providing a balanced summary of the field that will be useful for biologists at advanced undergraduate level and above. These general issues are illustrated by frequent reference to specific well-studied local and regional assemblages -- an approach that serves to relate the macroecological perspective (which is perhaps often difficult to comprehend) to the everyday experience of local sites. Macroecology is an expanding and dynamic discipline. The broad aim of the book is to promote an understanding of why it is such an important part of the wider program of research into ecology. Summarises the current macroecological literature. Provides numerous examples of key patterns. Explicitly links local and regional scale processes. Exploits detailed knowledge of one species assemblage to explore broad issues in the structuring of biodiversity.

Book Description
Community ecology is the study of the interactions between populations of co-existing species. Co-edited by two prominent community ecologists and featuring contributions from top researchers in the field, this book provides a survey of the state-of-the-art in both the theory and applications of the discipline. It pays special attention to topology, dynamics, and the importance of spatial and temporal scale while also looking at applications to emerging problems in human-dominated ecosystems (including the restoration and reconstruction of viable communities). Community Ecology: Processes, Models, and Applications adopts a mainly theoretical approach and focuses on the use of network-based theory, which remains little explored in standard community ecology textbooks. The book includes discussion of the effects of biotic invasions on natural communities; the linking of ecological network structure to empirically measured community properties and dynamics; the effects of evolution on community patterns and processes; and the integration of fundamental interactions into ecological networks. A final chapter indicates future research directions for the discipline.

Book Description
Community ecology has undergone a transformation in recent years, from a discipline largely focused on processes occurring within a local area to a discipline encompassing a much richer domain of study, including the linkages between communities separated in space (metacommunity dynamics), niche and neutral theory, the interplay between ecology and evolution (eco-evolutionary dynamics), and the influence of historical and regional processes in shaping patterns of biodiversity. To fully understand these new developments, however, students continue to need a strong foundation in the study of species interactions and how these interactions are assembled into food webs and other ecological networks. This new edition fulfils the book's original aims, both as a much-needed up-to-date and accessible introduction to modern community ecology, and in identifying the important questions that are yet to be answered. This research-driven textbook introduces state-of-the-art community ecology to a new generation of students, adopting reasoned and balanced perspectives on as-yet-unresolved issues. Community Ecology is suitable for advanced undergraduates, graduate students, and researchers seeking a broad, up-to-date coverage of ecological concepts at the community level.

Book Description
From climate change to species extinction, humanity is confronted with an increasing array of societal and environmental challenges that defy simple quantifiable solutions. Complexity-based ecology provides a new paradigm for ecologists and conservationists keen to embrace the uncertainty that is pressed upon us. This book presents key research papers chosen by some sixty scholars from various continents, across a diverse span of sub-disciplines. The papers are set alongside first person commentary from many of the seminal voices involved, offering unprecedented access to experts' viewpoints. The works assembled also shed light on the process of science in general, showing how the shifting of wider perspectives allows for new ideas to take hold. Ideal for undergraduate and advanced students of ecology and conservation, their educators and those working across allied fields, this is the first book of its kind to focus on complexity-based approaches and provides a benchmark for future collected volumes.
