Available in PDF, EPUB and Kindle. Book excerpt: At last both ecology and evolution are covered in this study on the dynamics of size-structured populations. How does natural selection shape growth patterns and life cycles of individuals, and hence the size-structure of populations? This book will stimulate biologists to look into some important and interesting biological problems from a new angle of approach, concerning: - life history evolution, - intraspecific competition and niche theory, - structure and dynamics of ecological communities.

Download or read book Design and Analysis of Ecological Experiments written by Samuel M. Scheiner and published by Oxford University Press. This book was released on 2001-04-26 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological research and the way that ecologists use statistics continues to change rapidly. This second edition of the best-selling Design and Analysis of Ecological Experiments leads these trends with an update of this now-standard reference book, with a discussion of the latest developments in experimental ecology and statistical practice. The goal of this volume is to encourage the correct use of some of the more well known statistical techniques and to make some of the less well known but potentially very useful techniques available. Chapters from the first edition have been substantially revised and new chapters have been added. Readers are introduced to statistical techniques that may be unfamiliar to many ecologists, including power analysis, logistic regression, randomization tests and empirical Bayesian analysis. In addition, a strong foundation is laid in more established statistical techniques in ecology including exploratory data analysis, spatial statistics, path analysis and meta-analysis. Each technique is presented in the context of resolving an ecological issue. Anyone from graduate students to established research ecologists will find a great deal of new practical and useful information in this current edition.
Download or read book The Dynamics of Arthopod Predator Prey Systems MPB 13 Volume 13 written by Michael Patrick Hassell and published by Princeton University Press. This book was released on 2020-03-31 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study of arthropod predador-prey systems Michael Hassell shows how many of the components of predation may be simply modeled in order to reveal their effects on the overall dynamics of the interacting populations. Arthropods, particularly insects, make ideal subjects for such a study because their generation times are characteristically short and many have relatively discrete generations, inviting the use of difference equation models to describe population changes. Using analytical models framed in difference equations, Dr. Hassell is able to show how the detailed biological processes of insect predator-prey (including host-parasitoid) interactions may be understood. Emphasizing the development and subsequent stability analysis of general models, the author considers in detail several crucial components of predator-prey models: the prey's rate of increase as a function of density, non-random search, mutual interference, and the predator's rate of increase as a function of predator survival and fecundity. Drawing on the correspondence between the models and field and laboratory data, Dr. Hassell then discusses the practical implications for biological pest control and suggests how such models may help to formulate a theoretical basis for biological control practices.
Download or read book Individual Behavior and Community Dynamics written by John Fryxell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: A book blending evolution and trophic dynamics, taking into account recent advances in both behavioral and population ecology, is long overdue. A central objective of this book is to consider whether adaptive behavioral decisions on the individual organism level might tend to stabilize trophic interactions. A second major goal of the book is to explore the implications of presumably adaptive behaviors on trophic dynamics and the implications of trophic dynamics for the evolution of adaptive behaviors. All evolutionary biologists, ecologists, and behavioral ecologists should find this exciting volume essential reading.

Download or read book Predator prey Dynamics The Interaction Among Intraspecific Competition Predator Avoidance and Spatial Distributions written by Jennifer Ann Nelson and published by . This book was released on 2006 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prey interact not only with their predators, but also conspecifics, and must balance the conflicting need of gathering resources and avoiding predation. In this study, I examine the effect of spatial dynamics, predation, and intraspecific competition on predator-prey population dynamics using ordinary, partial, and integro-differential equation models. Specifically, the Rosenzweig-MacArthur predator-prey model is modified to examine the effect that differences between the two species' spatial distributions have on coexistence of predators and prey and the short-term effects of predation on prey aggregations.

Download or read book Nonlinear Dynamics of Interacting Populations written by A. D. Bazykin and published by World Scientific. This book was released on 1998 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a systematic study of ecological communities of two or three interacting populations. Starting from the Lotka-Volterra system, various regulating factors are considered, such as rates of birth and death, predation and competition. The different factors can have a stabilizing or a destabilizing effect on the community, and their interplay leads to increasingly complicated behavior. Studying and understanding this path to greater dynamical complexity of ecological systems constitutes the backbone of this book. On the mathematical side, the tool of choice is the qualitative theory of dynamical systems — most importantly bifurcation theory, which describes the dependence of a system on the parameters. This approach allows one to find general patterns of behavior that are expected to be observed in ecological models. Of special interest is the reaction of a given model to disturbances of its present state, as well as to changes in the external conditions. This leads to the general idea of “dangerous boundaries” in the state and parameter space of an ecological system. The study of these boundaries allows one to analyze and predict qualitative and often sudden changes of the dynamics — a much-needed tool, given the increasing antropogenic load on the biosphere.As a spin-off from this approach, the book can be used as a guided tour of bifurcation theory from the viewpoint of application. The interested reader will find a wealth of intriguing examples of how known bifurcations occur in applications. The book can in fact be seen as bridging the gap between mathematical biology and bifurcation theory.

Download or read book Competition and Coexistence written by Ulrich Sommer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question "Why are there so many species?" has puzzled ecologist for a long time. Initially, an academic question, it has gained practical interest by the recent awareness of global biodiversity loss. Species diversity in local ecosystems has always been discussed in relation to the problem of competi tive exclusion and the apparent contradiction between the competitive exclu sion principle and the overwhelming richness of species found in nature. Competition as a mechanism structuring ecological communities has never been uncontroversial. Not only its importance but even its existence have been debated. On the one extreme, some ecologists have taken competi tion for granted and have used it as an explanation by default if the distribu tion of a species was more restricted than could be explained by physiology and dispersal history. For decades, competition has been a core mechanism behind popular concepts like ecological niche, succession, limiting similarity, and character displacement, among others. For some, competition has almost become synonymous with the Darwinian "struggle for existence", although simple plausibility should tell us that organisms have to struggle against much more than competitors, e.g. predators, parasites, pathogens, and envi ronmental harshness.
Download or read book Predator and Prey Population Dynamics and Distribution written by Julie Lynn McKnight and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The landscape in which common weasels ('Mustela nivalis vulgaris '), and field voles ('Microtus agrestis') live and weasel dispersal ability affect population dynamics in Kielder Forest, Northern England. Grassed clear-cuts (the primary habitat for voles and weasels) within Kielder are not 'islands' but in fact habitat patches that are highly connected by linear features. It is possible that the mobility of common weasels in Kielder Forest may cause decreased amplitude of the vole population cycle. Small mustelids should not experience increased energetic cost and/or mortality when dispersing to exploitable patches because they are not moving through unsuitable, non-prey habitat. My findings suggest that connectivity between suitable habitat patches and specialist predator dispersal ability are important variables that require consideration when researching the impact of predators on small rodent dynamics. A bait station database was used to identify carnivore associations in the Cape Breton Highlands, NovaScotia. Carnivore abundance and distribution may be influenced by interference and resource competition. Species association patterns were used to infer interspecific interactions. Red fox (' Vulpes vulpes') were absent from bait stations with either coyotes ('Canis latrans') or lynx ('Felis lynx'). It may be that red foxes were not present in these areas due to different habitat preferences, active avoidance of areas where lynx or coyote are abundant, or high predation of foxes. A positive species association was found for red fox and short-tailed weasel ('Mustela erminea'). This positive association may be the result of high niche overlap between foxes and weasels. It is likely that interspecific interactions, especially interference competition, shape the carnivore community of the Cape Breton Highlands. Further research is required for red foxes, as they may be severely affected by competition.
