Download or read book Stochastic Foundations in Movement Ecology written by Vicenç Méndez and published by Springer Science & Business Media. This book was released on 2013-09-18 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the fundamental theory for non-standard diffusion problems in movement ecology. Lévy processes and anomalous diffusion have shown to be both powerful and useful tools for qualitatively and quantitatively describing a wide variety of spatial population ecological phenomena and dynamics, such as invasion fronts and search strategies. Adopting a self-contained, textbook-style approach, the authors provide the elements of statistical physics and stochastic processes on which the modeling of movement ecology is based and systematically introduce the physical characterization of ecological processes at the microscopic, mesoscopic and macroscopic levels. The explicit definition of these levels and their interrelations is particularly suitable to coping with the broad spectrum of space and time scales involved in bio-ecological problems. Including numerous exercises (with solutions), this text is aimed at graduate students and newcomers in this field at the interface of theoretical ecology, mathematical biology and physics.

Download or read book Building a Foundation for Sound Environmental Decisions written by National Research Council and published by National Academies Press. This book was released on 1997-08-01 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decades, environmental problems have attracted enormous attention and public concern. Many actions have been taken by the U.S. Environmental Protection Agency and others to protect human health and ecosystems from particular threats. Despite some successes, many problems remain unsolved and new ones are emerging. Increasing population and related pressures, combined with a realization of the interconnectedness and complexity of environmental systems, present new challenges to policymakers and regulators. Scientific research has played, and will continue to play, an essential part in solving environmental problems. Decisions based on incorrect or incomplete understanding of environmental systems will not achieve the greatest reduction of risk at the lowest cost. This volume describes a framework for acquiring the knowledge needed both to solve current recognized problems and to be prepared for the kinds of problems likely to emerge in the future. Many case examples are included to illustrate why some environmental control strategies have succeeded where others have fallen short and how we can do better in the future.
Download or read book Turbulent Diffusion in the Environment written by G.T. Csanady and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rather excessive public preoccupation of the immediate past with what has been labeled the 'environmental crisis' is now fortunately being replaced by a more sus tained and rational concern with pollution problems by public administrators, engineers, and scientists. It is to be expected that members of the engineering profes sion will in the future widely be called upon to design disposal systems for gaseous and liquid wastes which meet strict pollution control regulations and to advise on possible improvements to existing systems of this kind. The engineering decisions involved will have to be based on reasonably accurate quantitative predictions of the effects of pollutants introduced into the atmosphere, ocean, lakes and rivers. A key input for such calculations comes from the theory of turbulent diffusion, which enables the prediction of the concentrations in which pollutants may be found in the neighborhood of a release duct, such as a chimney or a sewage outfall. Indeed the role of diffusion theory in pollution prediction may be likened to the role of applied mechanics (,strength of materials') in the design of structures for adequate strength. At least a certain group of engineers will have to be proficient in applying this particular branch of science to practical problems. At present, training in the theory of turbulent diffusion is available only at the gra duate level and then only in a very few places.
Download or read book Mathematical Ecology of Populations and Ecosystems written by John Pastor and published by John Wiley & Sons. This book was released on 2011-08-31 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: MATHEMATICAL ECOLOGY Population ecologists study how births and deaths affect the dynamics of populations and communities, while ecosystem ecologists study how species control the flux of energy and materials through food webs and ecosystems. Although all these processes occur simultaneously in nature, the mathematical frameworks bridging the two disciplines have developed independently. Consequently, this independent development of theory has impeded the cross-fertilization of population and ecosystem ecology. Using recent developments from dynamical systems theory, this advanced undergraduate/graduate level textbook shows how to bridge the two disciplines seamlessly. The book shows how bifurcations between the solutions of models can help understand regime shifts in natural populations and ecosystems once thresholds in rates of births, deaths, consumption, competition, nutrient inputs, and decay are crossed. Mathematical Ecology is essential reading for students of ecology who have had a first course in calculus and linear algebra or students in mathematics wishing to learn how dynamical systems theory can be applied to ecological problems.

Available in PDF, EPUB and Kindle. Book excerpt: "A bold and successful attempt to illustrate the theoretical foundations of all of the subdisciplines of ecology, including basic and applied, and extending through biophysical, population, community, and ecosystem ecology. Encyclopedia of Theoretical Ecology is a compendium of clear and concise essays by the intellectual leaders across this vast breadth of knowledge."--Harold Mooney, Stanford University "A remarkable and indispensable reference work that also is flexible enough to provide essential readings for a wide variety of courses. A masterful collection of authoritative papers that convey the rich and fundamental nature of modern theoretical ecology."--Simon A. Levin, Princeton University "Theoretical ecologists exercise their imaginations to make sense of the astounding complexity of both real and possible ecosystems. Imagining a real or possible topic left out of the Encyclopedia of Theoretical Ecology has proven just as challenging. This comprehensive compendium demonstrates that theoretical ecology has become a mature science, and the volume will serve as the foundation for future creativity in this area."--Fred Adler, University of Utah "The editors have assembled an outstanding group of contributors who are a great match for their topics. Sometimes the author is a key, authoritative figure in a field; and at other times, the author has enough distance to convey all sides of a subject. The next time you need to introduce ecology students to a theoretical topic, you'll be glad to have this encyclopedia on your bookshelf."--Stephen Ellner, Cornell University “Everything you wanted to know about theoretical ecology, and much that you didn’t know you needed to know but will now! Alan Hastings and Louis Gross have done us a great service by bringing together in very accessible form a huge amount of information about a broad, complicated, and expanding field.”--Daniel Simberloff, University of Tennessee, Knoxville
Download or read book Deterministic Aspects of Mathematical Demography written by J. Impagliazzo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical Demography, the study of population and its analysis through mathematical models, has received increased interest in the mathematical com munity in recent years. It was not until the twentieth century, however, that the study of population, predominantly human population, achieved its math ematical character. The subject of mathematical demography can be viewed from either a deterministic viewpoint or from a stochastic viewpoint. For the sake of brevity, stochastic models are not included in this work. It is, therefore, my intention to consider only established deterministic models in this discussion, starting with the life table as the earliest model, to a generalized matrix model which is developed in this treatise. These deterministic models provide sufficient de velopment and conclusions to formulate sound mathematical population analy sis and estimates of population projections. It should be noted that although the subject of mathematical demography focuses on human populations, the development and results may be applied to any population as long as the preconditions that make the model valid are maintained. Information concerning mathematical demography is at best fragmented.

Download or read book Stimulating the diffusion of environmental technologies through export written by Wisdom Kanda and published by Linköping University Electronic Press. This book was released on 2017-08-31 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contemporary environmental problems represent complex societal challenges, and as these problems become increasingly global, the international diffusion of environmental technologies is essential. One way to diffuse technologies internationally is through export. Despite the potential benefits from the adoption of environmental technologies, their export is stifled by externalities and free-rider problems. From this background, the aim of this thesis is to analyse how to stimulate the diffusion of environmental technologies through export. This aim is operationalised using four research questions, which focus on governmental initiatives to promote environmental technology export and their perceived effectiveness among targeted firms, obstacles to and drivers for export among municipally owned companies, the use of international city networks to facilitate environmental technology export and components of business concepts for environmental technology export. These questions are explored in the Swedish context using document analyses, interviews and internet surveys in a compilation thesis which consists of a cover essay and an appendix of five scientifically peer-reviewed and published journal articles. The conclusions are that governmental export promotion initiatives are often generic for all kinds of exporters, including environmental technologies, and comprise financial support, information provision, education and training, and trade and mobility-related programs, often with little incorporation of the specific characteristics of environmental technologies which many exporters perceive as ineffective. Municipally owned companies experience different barriers to and drivers for engaging in international activities compared to privately owned companies, and are often involved in international projects which are not always commercial export. International city networks serve as important arenas for bi-directional information sharing and learning regarding market characteristics, environmental challenges and potential solutions, building legitimacy for technologies and their suppliers. Regarding components of business concepts for the export of environmental technologies, regulation, legitimacy and private-public partnership are identified as particularly important based on the complexity and systemic nature of environmental technologies. Altogether, this thesis makes a contribution by conceptualising the export of environmental technologies with emphasis on technology characteristics, the technology supplier including their business concepts, obstacles to and drivers for export, technology adopters and their characterisation, communication channels and the diffusion context. For policy makers, a dynamic approach to environmental technology export promotion, in which specific attributes of environmental technologies and their suppliers are considered along their international business development, is suggested as a complement to existing generic initiatives. The possibility to provide such support should be reconciled with resource effectiveness, heterogeneity among companies and the complementary role of governmental interventions to market initiatives. Finally, partnerships between publicly and privately owned companies are suggested as particularly relevant since they build on the long-term experience, functioning proof-of-concept and legitimacy of publicly owned companies together with the competitiveness and flexibility of privately owned companies. These attributes could help overcome the liabilities of foreignness and newness, as well as resource constraints which challenge environmental technology export.
