Available in PDF, EPUB and Kindle. Book excerpt: An ecosystem's complexity develops from the vast numbers of species interacting in ecological communities. The nature of these interactions, in turn, depends on environmental context. How do these components together influence an ecosystem's behavior as a whole? Can ecologists resolve an ecosystem's complexity in order to predict its response to disturbances? Resolving Ecosystem Complexity develops a framework for anticipating the ways environmental context determines the functioning of ecosystems. Oswald Schmitz addresses the critical questions of contemporary ecology: How should an ecosystem be conceptualized to blend its biotic and biophysical components? How should evolutionary ecological principles be used to derive an operational understanding of complex, adaptive ecosystems? How should the relationship between the functional biotic diversity of ecosystems and their properties be understood? Schmitz begins with the universal concept that ecosystems are comprised of species that consume resources and which are then resources for other consumers. From this, he deduces a fundamental rule or evolutionary ecological mechanism for explaining context dependency: individuals within a species trade off foraging gains against the risk of being consumed by predators. Through empirical examples, Schmitz illustrates how species use evolutionary ecological strategies to negotiate a predator-eat-predator world, and he suggests that the implications of species trade-offs are critical to making ecology a predictive science. Bridging the traditional divides between individuals, populations, and communities in ecology, Resolving Ecosystem Complexity builds a systematic foundation for thinking about natural systems.
Download or read book Ecology and Ecosystem Conservation written by Oswald J. Schmitz and published by Island Press. This book was released on 2013-03-19 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meeting today’s environmental challenges requires a new way of thinking about the intricate dependencies between humans and nature. Ecology and Ecosystem Conservation provides students and other readers with a basic understanding of the fundamental principles of ecological science and their applications, offering an essential overview of the way ecology can be used to devise strategies to conserve the health and functioning of ecosystems. The book begins by exploring the need for ecological science in understanding current environmental issues and briefly discussing what ecology is and isn’t. Subsequent chapters address critical issues in conservation and show how ecological science can be applied to them. The book explores questions such as: • What is the role of ecological science in decision making? • What factors govern the assembly of ecosystems and determine their response to various stressors? • How does Earth’s climate system function and determine the distribution of life on Earth? • What factors control the size of populations? • How does fragmentation of the landscape affect the persistence of species on the landscape? • How does biological diversity influence ecosystem processes? The book closes with a final chapter that addresses the need not only to understand ecological science, but to put that science into an ecosystem conservation ethics perspective.
Download or read book Sounds Ecologies Musics written by Aaron S. Allen and published by Oxford University Press. This book was released on 2023-08-23 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sounds, Ecologies, Musics poses exciting challenges and provides fresh opportunities for scholars, scientists, environmental activists, musicians, and listeners to consider music and sound from ecological standpoints. Authors in Part I examine the natural and built environment and how music and sound are woven into it, how the environment enables music and sound, and how the natural and cultural production of music and sound in turn impact the environment. In Part II, contributors consider music and sound in relation to ecological knowledges that appear to conflict with, yet may be viewed as complementary to, Western science: traditional and Indigenous ecological and environmental knowledges. Part III features multidisciplinary and interdisciplinary approaches by scholars, scientists, and practitioners who probe the ecological imaginary regarding the complex ideas and contested keywords that characterize ecomusicology: sound, music, culture, society, environment, and nature. A common theme across the book is the idea of diverse ecologies. Once confined to the natural sciences, the word "ecology" is common today in the social sciences, humanities, and arts - yet its diverse uses have become imprecise and confusing. Engaging the conflicting and complementary meanings of "ecology" requires embracing a both/and approach. Diverse ecologies are illustrated in the methodological, terminological, and topical variety of the chapters as well as the contributors' choice of sources and their disciplinary backgrounds. In times of mounting human and planetary crises, Sounds, Ecologies, Musics challenges disciplinarity and broadens the interdisciplinary field of ecomusicologies. These theoretical and practical studies expand sonic, scholarly, and political activism from the diversity-equity-inclusion agenda of social justice to embrace the more diverse and inclusive agenda of ecocentric ecojustice.

Download or read book Natural Enemies written by Ann E. Hajek and published by Cambridge University Press. This book was released on 2018-07-26 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second edition of Natural Enemies will give students, professionals, and anyone wishing to learn the basics of biological control a fully updated and thorough introduction. The book discusses the huge diversity of organisms used in the control of pests, weeds and plant pathogens, and compares the many different strategies referred to as 'biological control': the introduction of exotic natural enemies, application of predators, parasitoids, and microorganisms as biopesticides, and manipulation of the environment to enhance natural enemy populations. The authors present the ecological concepts which form the bases of biological control and discuss recent changes to make biological control safe for the environment. Case studies are included throughout, providing in-depth examples of the use of different organisms and strategies in a variety of ecosystems. A new chapter covers the current challenges; the impact of climate change, the problem of invasive species, and how biological control can aid sustainability.
Download or read book Relentless Evolution written by John N. Thompson and published by University of Chicago Press. This book was released on 2013-04-15 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: At a glance, most species seem adapted to the environment in which they live. Yet species relentlessly evolve, and populations within species evolve in different ways. Evolution, as it turns out, is much more dynamic than biologists realized just a few decades ago. In Relentless Evolution, John N. Thompson explores why adaptive evolution never ceases and why natural selection acts on species in so many different ways. Thompson presents a view of life in which ongoing evolution is essential and inevitable. Each chapter focuses on one of the major problems in adaptive evolution: How fast is evolution? How strong is natural selection? How do species co-opt the genomes of other species as they adapt? Why does adaptive evolution sometimes lead to more, rather than less, genetic variation within populations? How does the process of adaptation drive the evolution of new species? How does coevolution among species continually reshape the web of life? And, more generally, how are our views of adaptive evolution changing? Relentless Evolution draws on studies of all the major forms of life—from microbes that evolve in microcosms within a few weeks to plants and animals that sometimes evolve in detectable ways within a few decades. It shows evolution not as a slow and stately process, but rather as a continual and sometimes frenetic process that favors yet more evolutionary change.
Download or read book Modeling Populations of Adaptive Individuals written by Steven F. Railsback and published by Princeton University Press. This book was released on 2020-05-19 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book offers a new theory for modeling how organisms make tradeoff decisions and how these decisions affect both individuals and populations. Tradeoff decisions (or behaviors) are those that are optimize survival and include behaviors like foraging and reproduction. Existing theories have not painted a complete picture of tradeoff decisions because they only observe how the decisions of an individual affect them rather than how individuals impact, and are impacted by, the behavior of their communities. The authors' theory-which they call state and prediction based theory-uses individual-based models since these models show the complex ways that organisms relate to their environment. The authors' broader approach, one that integrates behavior and population dynamics, allows ecologists to see how individuals make adaptive tradeoff decisions. In simpler terms, this theory does not assume, as the previous models do, that future conditions are fixed, known, and unaffected by the behavior of others. Instead, the authors assume individuals make decisions like people do, which is by forecasting future conditions, using approximation to make good decisions, and updating their choices as conditions change"--
Download or read book Advances in Fisheries Science written by Andrew I. L. Payne and published by John Wiley & Sons. This book was released on 2009-01-22 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely book brings readers up to date on the wide range of advances made in fisheries science since the publication in 1957 of On the Dynamics of Exploited Fish Populations (Beverton and Holt), regarded by many fisheries scientists as one of the most important books on fisheries yet published. Traditional fishery subjects covered include historic declines and changes in fishing fleets, fisheries management and stock assessments, data-poor situations, simulation and modelling of fished stocks, fisheries economics, assessing reproductive potential and dispersal of larvae, fisheries for sharks and rays, and use of marine technology. Additionally, related subjects of increasing importance now that ecological approaches to management are coming to the fore are presented. They include benthic ecology, ecosystem changes linked to fishing, life history theory, the effects of chemicals on fish reproduction, and use of sounds in the sea by marine life. Several chapters offer stimulating philosophical discussion of the many controversial areas still existing. This significant book, edited by Andy Payne, John Cotter and Ted Potter and containing contributions by world-renowned fisheries scientists, including many based at Cefas (where Beverton and Holt's original work was carried out) is an essential purchase for fisheries managers and scientists, fish biologists, marine scientists and ecologists. Libraries in all universities and research establishments where fisheries and biological sciences are studied and taught are likely to need copies of this landmark publication.
Download or read book Evolutionary Theory written by Niles Eldredge and published by University of Chicago Press. This book was released on 2016-09-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The natural world is infinitely complex and hierarchically structured, with smaller units forming the components of larger systems: genes are components genomes, cells are building blocks of tissues and organs, individuals are members of populations, which, in turn, are parts of species. In the face of such awe inspiring complexity, scientists need tools like the hierarchy theory of evolution, which provides a theoretical framework and an interdisciplinary research program that aims to understand the way complex biological systems work and evolve. The multidisciplinary approach looks at the structure of the myriad intricate interactions across levels of organization that range from molecules to the biosphere. Evolutionary Theory: A Hierarchical Perspective provides an introduction to the theory, which is currently driving a great deal of research in bioinformatics and evolutionary theory. Written by a diverse and renowned group of contributors, and edited by the founder of Hierachy Theory Niles Eldredge, this work will help make transparent the fundamental patterns driving living sytems.
Download or read book Coexistence in Ecology written by Mark A. McPeek and published by Princeton University Press. This book was released on 2022-02-08 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive framework for understanding species coexistence Coexistence is the central concept in community ecology, but an understanding of this concept requires that we study the actual mechanisms of species interactions. Coexistence in Ecology examines the major features of these mechanisms for species that coexist at different positions in complex food webs, and derives empirical tests from model predictions. Exploring the various challenges species face, Mark McPeek systematically builds a model food web, beginning with an ecosystem devoid of life and then adding one species at a time. With the introduction of each new species, he evaluates the properties it must possess to invade a community and quantifies the changes in the abundances of other species that result from a successful invasion. McPeek continues this process until he achieves a multitrophic level food web with many species coexisting at each trophic level, from omnivores, mutualists, and pathogens to herbivores, carnivores, and basic plants. He then describes the observational and experimental empirical studies that can test the theoretical predictions resulting from the model analyses. Synthesizing decades of theoretical research in community ecology, Coexistence in Ecology offers new perspectives on how to develop an empirical program of study rooted in the natural histories of species and the mechanisms by which they actually interact with one another.
Download or read book The Future of Ethics written by Willis Jenkins and published by Georgetown University Press. This book was released on 2013-10-24 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Future of Ethics interprets the big questions of sustainability and social justice through the practical problems arising from humanity’s increasing power over basic systems of life. What does climate change mean for our obligations to future generations? How can the sciences work with pluralist cultures in ways that will help societies learn from ecological change? Traditional religious ethics examines texts and traditions and highlights principles and virtuous behaviors that can apply to particular issues. Willis Jenkins develops lines of practical inquiry through "prophetic pragmatism," an approach to ethics that begins with concrete problems and adapts to changing circumstances. This brand of pragmatism takes its cues from liberationist theology, with its emphasis on how individuals and communities actually cope with overwhelming problems. Can religious communities make a difference when dealing with these issues? By integrating environmental sciences and theological ethics into problem-based engagements with philosophy, economics, and other disciplines, Jenkins illustrates the wide understanding and moral creativity needed to live well in the new conditions of human power. He shows the significance of religious thought to the development of interdisciplinary responses to sustainability issues and how this calls for a new style of religious ethics.
Download or read book Time in Ecology written by Eric Post and published by Princeton University Press. This book was released on 2019-02-26 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecologists traditionally regard time as part of the background against which ecological interactions play out. In this book, Eric Post argues that time should be treated as a resource used by organisms for growth, maintenance, and offspring production. Post uses insights from phenology—the study of the timing of life-cycle events—to present a theoretical framework of time in ecology that casts long-standing observations in the field in an entirely new light. Combining conceptual models with field data, he demonstrates how phenological advances, delays, and stasis, documented in an array of taxa, can all be viewed as adaptive components of an organism’s strategic use of time. Post shows how the allocation of time by individual organisms to critical life history stages is not only a response to environmental cues but also an important driver of interactions at the population, species, and community levels. To demonstrate the applications of this exciting new conceptual framework, Time in Ecology uses meta-analyses of previous studies as well as Post’s original data on the phenological dynamics of plants, caribou, and muskoxen in Greenland.
Download or read book Aquatic Physiosphere Biosphere Dynamics and Modelling written by Aike Beckmann and published by Springer Nature. This book was released on 2021-02-10 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: This encyclopedia is a reference for aquatic physical, biological and biogeochemical sciences, collecting and connecting a number of topics, concepts and facts about aquatic systems and their scientific investigation. The scope of the book comprises the aquatic physiosphere-biosphere transition zone, an entity that encompasses both inanimate matter and collectives (the physiosphere) as well as living organisms and collectives (the biosphere). This combined approach is meaningful because both realms are intimately linked and because available methods of investigation are often similar. Much can be gained from considering both spheres at and across their interface jointly, and while there is a strong focus on marine systems, most concepts presented are also applicable to freshwater systems. This presented snapshot of knowledge of the transition zone between the aquatic physiosphere and biosphere is taken from a very specific angle: the point of view of a modeler. Modeling is not only a state-of-the-art mode of scientific investigation, but also requires the explicit specification of all assumptions (helping to avoid fallacies), and offers the advantage of being quantitative and allows for theoretical "what if" scenarios. As in any reference work, equal emphasis is given to fundamental facts, the definition of terms and the explanation of concepts, in an attempt to establish a joint language for physicists, biologists and biogeochemists. Although originating from a modeler's approach to nature, the resulting suite of compatible concepts may also be useful beyond modeling purposes. Furthermore, the material is presented in a condensed, straightforward way. Hence, the length of each entry is limited to one (occasionally two) pages, thus offering a quick introductory overview. This excludes lengthy derivations and very specialized details. The book is geared towards researchers, teachers and advanced students in the field of aquatic (marine and limnic) sciences, in particular those interested or involved in interdisciplinary work.

Download or read book The New Ecology written by Oswald J. Schmitz and published by Princeton University Press. This book was released on 2018-12-18 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our species has transitioned from being one among millions on Earth to the species that is single-handedly transforming the entire planet to suit its own needs. In order to meet the daunting challenges of environmental sustainability in this epoch of human domination--known as the Anthropocene--ecologists have begun to think differently about the interdependencies between humans and the natural world. This concise and accessible book provides the best available introduction to what this new ecology is all about--and why it matters more than ever before. Oswald Schmitz describes how the science of ecology is evolving to provide a better understanding of how human agency is shaping the natural world, often in never-before-seen ways. The new ecology emphasizes the importance of conserving species diversity, because it can offer a portfolio of options to keep our ecosystems resilient in the face of environmental change. It envisions humans taking on new roles as thoughtful stewards of the environment to ensure that ecosystems have the enduring capacity to supply the environmental services on which our economic well-being--and our very existence--depend. It offers the ecological know-how to maintain and enhance our planet's environmental performance and ecosystem production for the benefit of current and future generations. Informative and engaging, The New Ecology shows how today's ecology can provide the insights we need to appreciate the crucial role we play in this era of unprecedented global environmental transition. -- Provided by publisher.
Download or read book Shared Governance for Sustainable Working Landscapes written by Timothy M. Gieseke and published by CRC Press. This book was released on 2016-08-05 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustaining our agricultural landscapes is no longer just a technical, scientific or even political problem, but it has evolved into a socially complex, so-called wicked problem of conflicting social governance and economics. This creates an extreme economic obstacle where the value of ecosystem services remains low and diffuse and the transactions costs remain high and multiple.Using Uber-like business platform technology and a shared governance model, a symbiotic demand for environmental benefits is created. Enabling multi-sector transactions for environmental benefits, this platform innovation would remedy the "tragedy of the commons"; the economic nemesis to achieving landscape sustainability. In a nutshell, to sustain our agricultural landscapes a transdisciplinary approach supported by a shared governance model housed within a multi-sided platform in needed. This book introduces an assessment framework identifying governance actors, styles and ratios for socio-ecological systems. The assessment uses a new governance compass to identify the types of actors completing which tasks and identifies the styles of governance used to complete the tasks. It is aimed to anyone involved in sustainability science, agricultural policy planning, or integrated landscape design.
