Book Description: One of the themes of the 20th International Congress of Entomology held in Florence in August 1996 was Ecology and Population Dynamics, with papers presented on single species dynamics, population interactions, and community ecology. This book contains a selection of the papers that were presented, and gives a late-1990s picture of the latest research in this fast developing area.

Book Description: Most organisms show substantial changes in size or morphology after they become independent of their parents and have to find their own food. Furthermore, the rate at which these changes occur generally depends on the amount of food they ingest. In this book, André de Roos and Lennart Persson advance a synthetic and individual-based theory of the effects of this plastic ontogenetic development on the dynamics of populations and communities. De Roos and Persson show how the effects of ontogenetic development on ecological dynamics critically depend on the efficiency with which differently sized individuals convert food into new biomass. Differences in this efficiency--or ontogenetic asymmetry--lead to bottlenecks in and thus population regulation by either maturation or reproduction. De Roos and Persson investigate the community consequences of these bottlenecks for trophic configurations that vary in the number and type of interacting species and in the degree of ontogenetic niche shifts exhibited by their individuals. They also demonstrate how insights into the effects of maturation and reproduction limitation on community equilibrium carry over to the dynamics of size-structured populations and give rise to different types of cohort-driven cycles. Featuring numerous examples and tests of modeling predictions, this book provides a pioneering and extensive theoretical and empirical treatment of the ecology of ontogenetic growth and development in organisms, emphasizing the importance of an individual-based perspective for understanding population and community dynamics.

Book Description: "Chapter 1 establishes the context of such a search for pattern, presenting essential definitions and exploring early work on community structure and organization. The various biotic and abiotic factors which may influence communities and their dynamics are reviewed in Chapter 2, while the way in which the interrelationships between organisms are structured within the community in food webs or in the partitioning of available resources are considered in separate chapters on food webs, niche relationships and species guilds. Later chapters explore the factors determining the assembly of communities, species composition and pattern of relative abundance and the relative roles of deterministic and stochastic processes in determining community structure. The concluding section explores the implications of observed patterns of structure and organization for stability. The mathematical analyses which are an essential component of this topic are included only where essential for understanding and are presented in special box features. Each mathematical section has been carefully structured and fully explained in biological terms. Community Ecology presents a refreshingly readable course text for advanced undergraduates in ecology."--BOOK JACKET.

Book Description: Part of the Zoological Society of London's Conservation Science and Practice Series, Applied Population and Community Ecology evaluates theory in population and community ecology using a case study of feral pigs, birds and plants in the high country of south-eastern Australia. In sequence, the book reviews the relevant theory and uses long-term research over a quarter of a century on the population ecology of feral pigs and then community ecology of birds and plants, to evaluate the theory. The book brings together into one volume, research results of many observational, experimental and modelling studies and directly compares them with those from related studies around the world. The implications of the results for future wildlife management are also discussed. Intended readers are ecologists, graduate students in ecology and wildlife management and conservation and pest managers.

Book Description: Diese Softcover-Ausgabe, die ein unveränderter Nachdruck der 2. Auflage (2009) ist, hält das nachgefragte Lehrbuch weiterhin verfügbar. Moderne Ökologie von A bis Z Das renommierte Autorenteam Townsend, Begon und Harper konzentriert sich in diesem Lehrbuch auf die wesentlichen Zusammenhänge in der Ökologie. In anschaulicher, durchgehend vierfarbig gestalteter und leicht verständlicher Form wird ein ausgewogener Überblick vermittelt, der die terrestrische und aquatische Ökologie gleichermaßen berücksichtigt. Für den Praxisbezug wurde großes Gewicht auf die angewandten Aspekte gelegt. Zahlreiche didaktische Elemente und großzügige, farbige Illustrationen erleichtern den Zugang. Es gibt Schlüsselkonzepte am Kapitelanfang, "Fenster" für historische Einschübe, mathematische Hintergründe und ethische Fragen, Zusammenfassungen und Fragen am Kapitelende. Neu in dieser Auflage ist ein eigenes Kapitel zur Evolutionsökologie. Alle anderen Kapitel – insbesondere die zu den angewandte Aspekten – wurden intensiv überarbeitet und hunderte neue Beispiele aufgenommen. Klar und einfach erklärt in diesem Buch.

Book Description: Worldwide, Population Ecology is the leading textbook on this titled subject. Written primarily for students, it describes the present state of population ecology in terms that can be readily understood by undergraduates with little or no background in the subject. Carefully chosen experimental examples illustrate each topic, and studies of plants and animals are combined to show how fundamental principles can be derived that apply to both species. Use of complex mathematics ia avoided throughout the book, and what math is necessary is dealt with by examination of real experimental data rather than dull theory. The latest edition of this leading textbook. Adopted as an Open University set text.

Book Description: All populations fluctuate stochastically, creating a risk of extinction that does not exist in deterministic models, with fundamental consequences for both pure and applied ecology. This book provides the most comprehensive introduction to stochastic population dynamics, combining classicalbackground material with a variety of modern approaches, including new and previously unpublished results by the authors, illustrated with examples from bird and mammal populations, and insect communities.Demographic and environmental stochasticity are introduced with statistical methods for estimating them from field data. The long-run growth rate of a population is explained and extended to include age structure with both deomgraphic and environmental stochasticity. Diffusion approximationsfacilitate the analysis of extinction dynamics and the duration of the final decline. Methods are developed for estimating delayed density dependence from population time series using life history data. Metapopulation viability and the spatial scale of population fluctuations and extinction risk areanalyzed. Stochastic dynamics and statistical uncertainty in population parameters are incorporated in Population Viability Analysis and strategies for sustainable harvesting.Statistics of species diversity measures and species abundance distributions are described, with implications for rapid assessments of biodiversity, and methods are developed for partitioning species diversity into additive components. Analysis of the stochastic dynamics of a tropical butterflycommunity in space and time indicates that most of the variance in the species abundance distribution is due to ecological heterogeneity among species, so that real communities are far from neutral.
