Description : Introduction to Population Ecology is an accessible and up-to-date textbook covering all aspects of population ecology. Discusses field and laboratory data to illustrate the fundamental laws of population ecology. Provides an overview of how population theory has developed. Explores single-species population growth and self-limitation; metapopulations; and a broad range of interspecific interactions including parasite-host, predator-prey, and plant-herbivore. Keeps the mathematics as simple as possible, using a careful step-by-step approach and including graphs and other visual aids to help understanding. Artwork from the book is available to instructors online at www.blackwellpublishing.com/rockwood and by request on CD-ROM.
Description : Discusses how to construct mathematical models of populations, the changing proportions of individuals of various ages, birthrate, the ecological niche, and population interaction in this technical introduction to population ecology
Description : A common tendency in the field of population ecology has been to overlook individual differences by treating populations as homogeneous units; conversely, in behavioral ecology the tendency has been to concentrate on how individual behavior is shaped by evolutionary forces, but not on how this behavior affects population dynamics. Adam Lomnicki and others aim to remedy this one-sidedness by showing that the overall dynamical behavior of populations must ultimately be understood in terms of the behavior of individuals. Professor Lomnicki's wide-ranging presentation of this approach includes simple mathematical models aimed at describing both the origin and consequences of individual variation among plants and animals. The author contends that further progress in population ecology will require taking into account individual differences other than sex, age, and taxonomic affiliation--unequal access to resources, for instance. Population ecologists who adopt this viewpoint may discover new answers to classical questions of population ecology. Partly because it uses a variety of examples from many taxonomic groups, this work will appeal not only to population ecologists but to ecologists in general.
Description : This book provides applied biologists and ecologists with the mathematical tools they need to understand the ever increasingly mathematical and complex area of population ecology.
Description : Provides a quantitative and Darwinian perspective on population biology, with problem sets, simulations and worked examples to aid the student.
Description : This completely revised, fourth edition of Introduction to PlantPopulation Biology continues the approach taken by its highlysuccessful predecessors. Ecological and genetic principles areintroduced and theory is made accessible by clear, accurateexposition with plentiful examples. Models and theoreticalarguments are developed gradually, requiring a minimum ofmathematics. The book emphasizes the particular characteristics of plantsthat affect their population biology, and evolutionary questionsthat are particularly relevant for plants. Wherever appropriate, itis shown how ecology and genetics interact, presenting a roundedpicture of the population biology of plants. Topics covered include variation and its inheritance, geneticmarkers including molecular markers, plant breeding systems,ecological genetics, intraspecific interactions, populationdynamics, regional dynamics and metapopulations, competition andcoexistence, and the evolution of breeding systems and lifehistory. An extensive bibliography provides access to the recentliterature that will be invaluable to students and academicsalike. Effective integration of plant population ecology, populationgenetics and evolutionary biology. The new edition is thoroughly revised and now includesmolecular techniques. The genetics chapters have been completely rewritten by a newco-author, Deborah Charlesworth.
Description : How can the future number of deer, agricultural pests, or cod be calculated based on the present number of individuals and their age distribution? How long will it take for a viral outbreak in a particular city to reach another city five hundred miles away? In addressing such basic questions, ecologists today are as likely to turn to complicated differential equations as to life histories--a dramatic change from thirty years ago. Population ecology is the mathematical backbone of ecology. Here, two leading experts provide the underlying quantitative concepts that all modern-day ecologists need. John Vandermeer and Deborah Goldberg show that populations are more than simply collections of individuals. Complex variables such as the size distribution of individuals and allotted territory for expanding groups come into play when mathematical models are applied. The authors build these models from the ground up, from first principles, using a much broader range of empirical examples--from plants to animals, from viruses to humans--than do standard texts. And they address several complicating issues such as age-structured populations, spatially distributed populations, and metapopulations. Beginning with a review of elementary principles, the book goes on to consider theoretical issues involving life histories, complications in the application of the core principles, statistical descriptions of spatial aggregation of individuals and populations as well as population dynamic models incorporating spatial information, and introductions to two-species interactions. Complemented by superb illustrations that further clarify the links between the mathematical models and biology, Population Ecology is the most straightforward and authoritative overview of the field to date. It will have broad appeal among undergraduates, graduate students, and practicing ecologists.
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.
Description : Population biology has been investigated quantitatively for many decades, resulting in a rich body of scientific literature. Ecologists often avoid this literature, put off by its apparently formidable mathematics. This textbook provides an introduction to the biology and ecology of populations by emphasizing the roles of simple mathematical models in explaining the growth and behavior of populations. The author only assumes acquaintance with elementary calculus, and provides tutorial explanations where needed to develop mathematical concepts. Examples, problems, extensive marginal notes and numerous graphs enhance the book's value to students in classes ranging from population biology and population ecology to mathematical biology and mathematical ecology. The book will also be useful as a supplement to introductory courses in ecology.
