Ecology

Autor: Michael Begon , Colin R. Townsend

Número de Páginas: 868

A definitive guide to the depth and breadth of the ecological sciences, revised and updated The revised and updated fifth edition of Ecology: From Individuals to Ecosystems – now in full colour – offers students and practitioners a review of the ecological sciences. The previous editions of this book earned the authors the prestigious ‘Exceptional Life-time Achievement Award’ of the British Ecological Society – the aim for the fifth edition is not only to maintain standards but indeed to enhance its coverage of Ecology. In the first edition, 34 years ago, it seemed acceptable for ecologists to hold a comfortable, objective, not to say aloof position, from which the ecological communities around us were simply material for which we sought a scientific understanding. Now, we must accept the immediacy of the many environmental problems that threaten us and the responsibility of ecologists to play their full part in addressing these problems. This fifth edition addresses this challenge, with several chapters devoted entirely to applied topics, and examples of how ecological principles have been applied to problems facing us highlighted throughout the remaining nineteen...

Fundamental Processes in Ecology

Autor: David M Wilkinson

Número de Páginas: 195

Fundamental Processes in Ecology presents a way to study ecosystems that is not yet available in ecology textbooks but is resonant with current thinking in the emerging fields of geobiology and Earth System Science. It provides an alternative, process-based classification of ecology and proposes a truly planetary view of ecological science. To achieve this, it asks (and endeavours to answer) the question, "what are the fundamental ecological processes which would be found on any planet with Earth-like, carbon based, life?" The author demonstrates how the idea of fundamental ecological processes can be developed at the systems level, specifically their involvement in control and feedback mechanisms. This approach allows us to reconsider basic ecological ideas such as energy flow, guilds, trade-offs, carbon cycling and photosynthesis; and to put these in a global context. In doing so, the book puts a much stronger emphasis on microorganisms than has traditionally been the case. The integration of Earth System Science with ecology is vitally important if ecological science is to successfully contribute to the massive problems and future challenges associated with global change....

The Fundamental Processes in Ecology

Autor: David M. Wilkinson

Número de Páginas: 177

This thought-provoking book introduces a way to study ecosystems that is resonant with current thinking in the fields of earth system science, geobiology, and planetology. Instead of organizing the subject around a hierarchical series of entities (e.g. genes, individuals, populations, species, communities, and the biosphere), the book provides an alternative process-based approach and proposes a truly planetary view of ecological science. It demonstrates how the idea of fundamental ecological processes can be developed at the systems level, specifically their involvement in control and feedback mechanisms. This enables the reader to reconsider fundamental ecological processes such as energy flow, guilds, trade-offs, carbon cycling, and photosynthesis, and to put them in a global (and even planetary) context. In so doing, the book places a much stronger emphasis on microorganisms. Since publication of the first edition in 2006, ever growing societal concern about environmental sustainability has ensured that the earth system science/Gaian approach has steadily gained traction. Its integration with ecology is now more important than ever if ecological science is to effectively...

The Theory of Ecology

Autor: Samuel M. Scheiner , Michael R. Willig

Número de Páginas: 416

Despite claims to the contrary, the science of ecology has a long history of building theories. Many ecological theories are mathematical, computational, or statistical, though, and rarely have attempts been made to organize or extrapolate these models into broader theories. The Theory of Ecology brings together some of the most respected and creative theoretical ecologists of this era to advance a comprehensive, conceptual articulation of ecological theories. The contributors cover a wide range of topics, from ecological niche theory to population dynamic theory to island biogeography theory. Collectively, the chapters ably demonstrate how theory in ecology accounts for observations about the natural world and how models provide predictive understandings. It organizes these models into constitutive domains that highlight the strengths and weaknesses of ecological understanding. This book is a milestone in ecological theory and is certain to motivate future empirical and theoretical work in one of the most exciting and active domains of the life sciences.

Distribution Ecology

Autor: Marcelo Hernán Cassini

Número de Páginas: 221

This book brings together a set of approaches to the study of individual-species ecology based on the analysis of spatial variations of abundance. Distribution ecology assumes that ecological phenomena can be understood when analyzing the extrinsic (environmental) or intrinsic (physiological constraints, population mechanisms) that correlate with this spatial variation. Ecological processes depend on geographical scales, so their analysis requires following environmental heterogeneity. At small scales, the effects of biotic factors of ecosystems are strong, while at large scales, abiotic factors such as climate, govern ecological functioning. Responses of organisms also depend on scales: at small scales, adaptations dominate, i.e. the ability of organisms to respond adaptively using habitat decision rules that maximize their fitness; at large scales, limiting traits dominate, i.e., tolerance ranges to environmental conditions.​

A Critique of Silviculture

Autor: Klaus J. Puettmann , K. David Coates , Christian C. Messier

Número de Páginas: 207

The discipline of silviculture is at a crossroads. Silviculturists are under increasing pressure to develop practices that sustain the full function and dynamics of forested ecosystems and maintain ecosystem diversity and resilience while still providing needed wood products. A Critique of Silviculture offers a penetrating look at the current state of the field and provides suggestions for its future development. The book includes an overview of the historical developments of silvicultural techniques and describes how these developments are best understood in their contemporary philosophical, social, and ecological contexts. It also explains how the traditional strengths of silviculture are becoming limitations as society demands a varied set of benefits from forests and as we learn more about the importance of diversity on ecosystem functions and processes. The authors go on to explain how other fields, specifically ecology and complexity science, have developed in attempts to understand the diversity of nature and the variability and heterogeneity of ecosystems. The authors suggest that ideas and approaches from these fields could offer a road map to a new philosophical and...

Ecology Revisited

Autor: Astrid Schwarz , Kurt Jax

Número de Páginas: 435

As concerns about humankind’s relationship with the environment move inexorably up the agenda, this volume tells the story of the history of the concept of ecology itself and adds much to the historical and philosophical debate over this multifaceted discipline. The text provides readers with an overview of the theoretical, institutional and historical formation of ecological knowledge. The varied local conditions of early ecology are considered in detail, while epistemological problems that lie on the borders of ecology, such as disunity and complexity, are discussed. The book traces the various phases of the history of the concept of ecology itself, from its 19th century origins and antecedents, through the emergence of the environmental movement in the later 20th century, to the future, and how ecology might be located in the environmental science framework of the 21st century. The study of ‘ecological’ phenomena has never been confined solely to the work of researchers who consider themselves ecologists. It is rather a field of knowledge in which a plurality of practices, concepts and theories are developed. Thus, there exist numerous disciplinary subdivisions and...

Infectious Disease Ecology

Autor: Richard S. Ostfeld , Felicia Keesing , Valerie T. Eviner

Número de Páginas: 521

News headlines are forever reporting diseases that take huge tolls on humans, wildlife, domestic animals, and both cultivated and native plants worldwide. These diseases can also completely transform the ecosystems that feed us and provide us with other critical benefits, from flood control to water purification. And yet diseases sometimes serve to maintain the structure and function of the ecosystems on which humans depend. Gathering thirteen essays by forty leading experts who convened at the Cary Conference at the Institute of Ecosystem Studies in 2005, this book develops an integrated framework for understanding where these diseases come from, what ecological factors influence their impacts, and how they in turn influence ecosystem dynamics. It marks the first comprehensive and in-depth exploration of the rich and complex linkages between ecology and disease, and provides conceptual underpinnings to understand and ameliorate epidemics. It also sheds light on the roles that diseases play in ecosystems, bringing vital new insights to landscape management issues in particular. While the ecological context is a key piece of the puzzle, effective control and understanding of...

Individual-based Methods in Forest Ecology and Management

Autor: Arne Pommerening , Pavel Grabarnik

Número de Páginas: 417

Model-driven individual-based forest ecology and individual-based methods in forest management are of increasing importance in many parts of the world. For the first time this book integrates three main fields of forest ecology and management, i.e. tree/plant interactions, biometry of plant growth and human behaviour in forests. Individual-based forest ecology and management is an interdisciplinary research field with a focus on how the individual behaviour of plants contributes to the formation of spatial patterns that evolve through time. Key to this research is a strict bottom-up approach where the shaping and characteristics of plant communities are mostly the result of interactions between plants and between plants and humans. This book unites important methods of individual-based forest ecology and management from point process statistics, individual-based modelling, plant growth science and behavioural statistics. For ease of access, better understanding and transparency the methods are accompanied by R code and worked examples.

Multitrophic Interactions in Terrestrial Systems

Autor: A. C. Gange , V. K. Brown

Número de Páginas: 474

Multitrophic interactions are now recognised as being of the utmost importance in understanding the complexity of the natural world. However, their complex nature had often been a barrier to their study as they require research teams composed of workers often with very disparate interests. This book therefore takes a multidisciplinary approach to complex interactions across many trophic levels and includes authors from disciplines as diverse as mycology, entomology, nematology, population ecology and theoretical ecology. Throughout, the direct and indirect interactions between organisms from different trophic levels are emphasised in comprehensive reviews, bringing a fresh, collaborative approach to community ecology. The book is ideal for those seeking an overview of our understanding of mulittrophic interactions as well as directions for future research.

Wildlife Population Growth Rates

Autor: R. M. Sibly , J. Hone , T. H. Clutton-brock

Número de Páginas: 372

What determines where a species lives? And what determines its abundance? This book takes a fresh approach to some of the classic questions in ecology. Despite great progress in the twentieth century much more remains to be done before we can provide full answers to these questions. The methods described and deployed in this book point the way forward. The core message of the book is that the key insights come from understanding what determines population growth rate, and that application of this approach will make ecology a more predictive science. Topics covered include population regulation, density-dependence, the ecological niche, resource and interference competition, habitat fragmentation and the ecological effects of environmental stress, together with applications to conservation biology, wildlife management, human demography and ecotoxicology. After a substantial introduction by the editors the book brings together contributions from leading scientists from Australia, New Zealand, North America, Europe and the U.K.

Landscape Ecology: A Widening Foundation

Autor: Vittorio Ingegnoli

Número de Páginas: 367

Exactly 25 years ago on a warm autumn afternoon a young ecologist walked slowly through a tiny oak wood, and perched on a log to reflect. He had measured and seemingly knew "all" the species present - trees, mosses, mushrooms, birds and more. The research, based on this and other woods in the landscape, was the first rigorous test to see if island biogeographic theory was of use in heterogeneous land. Unexpectedly, an interior-to-edge model was found to be more useful. But on this beautiful sunny day he gazed out through the trees at the surrounding bean and maize fields. Suddenly a terrible thought hit him. The land surrounding the other woods differed slightly from this scene. Here there were two bean fields plus a maize field, meadow, hedgerow and farm road, but the other comparably sized woods studied had different mixes of these land uses. Wouldn't the surroundings seriously affect the species in the woods? Had he done "bad science" (an awful feeling for a scientist)? Immediately he went to all his ecology books, searching for discussions of patchiness, mosaic pattern, interactions between ecosystems, and the like. Nothing. Surprise was a new ingredient to ponder. Then for 3...

Introductory Ecology

Autor: Peter Cotgreave , Irwin Forseth

Número de Páginas: 295

In this age of increasing human domination of the Earth's biological and physical resources, a basic understanding of ecology is more important than ever. Students need a textbook that introduces them to the basic principles of ecological science, one that is relevant to today's world, and one that does not overwhelm them with detail and jargon. Peter Cotgreave and Irwin Forseth have designed this book to meet the needs of these students, by providing a basic synthesis of how individual organisms interact with their physical environment, and with each other, to generate the complex ecosystems we see around us. The unifying theme of the book is biodiversity-its patterns, causes, and the growing worldwide threats to it. Basic ecological principles are illustrated using clearly described examples from the current ecological literature. This approach makes the book valuable to all students studying ecology. Examples have been chosen carefully to represent as wide a range of ecosystems (terrestrial and aquatic, northern and southern hemisphere) and life forms (animal, plant and microbe) as possible. Particular attention is paid to consequences of global change on organisms,...

Population Parameters

Autor: Hamish Mccallum

Número de Páginas: 360

Ecologists and environmental managers rely on mathematical models, both to understand ecological systems and to predict future system behavior. In turn, models rely on appropriate estimates of their parameters. This book brings together a diverse and scattered literature, to provide clear guidance on how to estimate parameters for models of animal populations. It is not a recipe book of statistical procedures. Instead, it concentrates on how to select the best approach to parameter estimation for a particular problem, and how to ensure that the quality estimated is the appropriate one for the specific purpose of the modelling exercise. Commencing with a toolbox of useful generic approaches to parameter estimation, the book deals with methods for estimating parameters for single populations. These parameters include population size, birth and death rates, and the population growth rate. For such parameters, rigorous statistical theory has been developed, and software is readily available. The problem is to select the optimal sampling design and method of analysis. The second part of the book deals with parameters that describe spatial dynamics, and ecological interactions such as...

Mario Bunge: A Centenary Festschrift

Autor: Michael R. Matthews

Número de Páginas: 829

This volume has 41 chapters written to honor the 100th birthday of Mario Bunge. It celebrates the work of this influential Argentine/Canadian physicist and philosopher. Contributions show the value of Bunge’s science-informed philosophy and his systematic approach to philosophical problems. The chapters explore the exceptionally wide spectrum of Bunge’s contributions to: metaphysics, methodology and philosophy of science, philosophy of mathematics, philosophy of physics, philosophy of psychology, philosophy of social science, philosophy of biology, philosophy of technology, moral philosophy, social and political philosophy, medical philosophy, and education. The contributors include scholars from 16 countries. Bunge combines ontological realism with epistemological fallibilism. He believes that science provides the best and most warranted knowledge of the natural and social world, and that such knowledge is the only sound basis for moral decision making and social and political reform. Bunge argues for the unity of knowledge. In his eyes, science and philosophy constitute a fruitful and necessary partnership. Readers will discover the wisdom of this approach and will gain...

Insect Natural Enemies

Autor: M.a. Jervis

Número de Páginas: 497

Over the past three decades there has been a dramatic increase in theoretical and practical studies on insect natural enemies. The appeal of insect predators, and parasitoids in particular, as research animals derives from the relative ease with which many species may be cultured and experimented with in the laboratory, the simple life cycles of most parasitoids, and the increasing demand for biological pest control. There is now a massive literature on insect natural enemies, so there is a great need for a general text that the enquiring student or research worker can use in deciding on approaches and techniques that are appropriate to the study and evaluation of such insects. This book fulfils that demand. A considerably updated and expanded version of a previous best-seller, it is an account of major aspects of the biology of predators and parasitoids, punctuated with information and advice on which experiments or observations to conduct, and how to carry them out. Guidance is provided, where necessary, on the literature that may need to be consulted on particular topics. While researchers can now refer to several books on parasitoids and predators, Insects as Natural Enemies...

Heritage Ecologies

Autor: Torgeir Rinke Bangstad , Þóra Pétursdóttir

Número de Páginas: 477

Heritage Ecologies presents an ecological understanding of heritage that furthers a concern for how its making and unmaking always involves a wide range of human and other-than-human actors. Recognizing the entangled nature-cultures of heritage is essential in the Anthropocene era, where uncertainty and rapid environmental change force us to recast common conceptions of inheritance and to envision new strategies for preservation. Heritage sites are meant to be open and shared spaces, and a recurring argument in the cases presented here is that this openness inevitably also overrides our selections, orders and appreciations. Through a diverse range of case studies, the chapters collected in this book aim to explore the affects and memories engendered by diverse heritage ecologies where humans are neither the sole makers nor the only inheritors. The common call is that the experiential, perceptive and informational plenitude enabled through contributions of other-than-human actors is key to an ecological rethinking of heritage in the twenty-first century. Heritage Ecologies is unique in bringing heritage studies into closer proximity with a wide variety of non-representational and...

Physical and Biological Bases of Life Stability

Autor: Victor G. Gorshkov

Número de Páginas: 335

It is well known that the biochemical processes of life on Earth are maintained by the external solar radiation and can be reduced to the synthesis and decomposition of organic matter. Man has added the synthesis and decomposition of various in dustrial products to these natural processes. On one hand, biological synthesis may only be conducted within the rather narrow margins of parameters of the environ ment, including temperature, humidity, concentrations of the inorganic substances used by life (such as carbon dioxide, oxygen, etc.) On the other hand, the physical and chemical composition of the environment suffers significant changes during those processes of synthesis and decomposition. The maximum possible rate of such change due to the activity of living beings can exceed the average geophysical rates of change of the environment due to activity ofterrestrial depths and cosmic processes by a factor often thousand. In the absence of a rigid correlation between the biological synthesis and decomposition, the environment would be greatly disturbed within a decade and driven into a state unfit for life. A lifeless Earth, however would suffer similar changes only after about a...

Successes, Limitations, and Frontiers in Ecosystem Science

Autor: Michael L. Pace , Peter M. Groffman

Número de Páginas: 515

Research on the ecosystems has emerged in recent decades as a vital, successful, and sometimes controversial approach to environmental science. Ecosystem science has addressed issues such as human alteration of biogeochemical cycles, ecological complexity and biodiversity, and ecological response to climate change. As a central and integrating science, ecosystem-level studies have been highly successful. This book emphasizes the idea that much of the progress in ecosystem research has been driven by the emergence of new environmental problems that could not be addressed by existing approaches. By focusing on successes, limitations, and frontiers in ecosystem studies, it will be welcomed by students and scientists throughout the ecological and environmental communities.
