Available in PDF, EPUB and Kindle. Book excerpt: From a mathematical point of view, physiologically structured population models are an underdeveloped branch of the theory of infinite dimensional dynamical systems. We have called attention to four aspects: (i) A choice has to be made about the kind of equations one extracts from the predominantly verbal arguments about the basic assumptions, and subsequently uses as a starting point for a rigorous mathematical analysis. Though differential equations are easy to formulate (different mechanisms don't interact in infinites imal time intervals and so end up as separate terms in the equations) they may be hard to interpret rigorously as infinitesimal generators. Integral equations constitute an attractive alternative. (ii) The ability of physiologically structured population models to increase our un derstanding of the relation between mechanisms at the i-level and phenomena at the p-level will depend strongly on the development of dynamical systems lab facilities which are applicable to this class of models. (iii) Physiologically structured population models are ideally suited for the for mulation of evolutionary questions. Apart from the special case of age (see Charlesworth 1980, Yodzis 1989, Caswell 1989, and the references given there) hardly any theory exists at the moment. This will, hopefully, change rapidly in the coming years. Again the development of appropriate software may turn out to be crucial.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding wildlife population ecology is vital for all wildlife managers and conservation biologists. Leopold draws on 30 years of research and teaching experience to give students and natural resource professionals the foundation they need to effectively manage wildlife populations. He begins with the key statistical concepts and research approaches necessary to gain insight into various models of population dynamics. The many factors that influence wildlife populations are thoroughly explored and their consequences are investigated. In addition, the author presents techniques for analyzing wildlife harvest data and a lucid discussion of valuable wildlife census methods. Frequent examples of foundational literature supplement each chapter with applications of the theories and provide a concise compendium of fundamental concepts of population ecology. Abundant statistical exercises reinforce students’ learning throughout the text.

Download or read book Frontiers in Ecology and Evolution 2020 Highlights written by Mark A. Elgar and published by Frontiers Media SA. This book was released on 2021-02-26 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: If nothing else, 2020 reminded us that, whether we like it or not, human society forms part of a broader ecological community that includes species with management challenges. My experience in Melbourne highlighted how environmental threats to humanity are best managed when governments adopt evidence-based strategies (that might also require incentives for human cooperation). Fundamental research, ranging from quantitative natural history to broader insights about ecological and evolutionary processes, invariably forms the backbone of such evidence. The collection of papers in this 2020 Highlights eBook represents a sample of articles in Frontiers in Ecology and Evolution that contribute to our collective wisdom in the discipline and generated sizeable interest among our readers. We hope you also find them interesting.
Download or read book Animal Population Ecology written by J Dempster and published by Elsevier. This book was released on 2012-12-02 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal Population Ecology focuses on the interaction between the various factors that affect an animal population. Population ecology is the study of the factors that determine the abundance of species and is concerned with the identification and mode of action of those environmental factors that cause fluctuations in population size and of those which determine the extent of these fluctuations. Organized into 11 chapters, the book initially examines some of the basic ideas about animal populations and defines many of the terms used by population ecologists. Then, it describes the action of the most important factors affecting population size. The interaction between these factors is demonstrated in chapters 8 and 9, wherein the results from studies of a few selected species are presented in detail. Finally, chapters 10 and 11 cover the development of generalized theories of population dynamics and their application to practical problems. With a strong focus on intensive study of animal populations in the field, rather than elaborate theories, the book will be helpful to population ecologists, animal researchers, teachers, and students.

Available in PDF, EPUB and Kindle. Book excerpt: This unique book is concerned with the general principles and theories of population ecology, based on the idea that the rules governing the dynamics of populations are relatively simple, and that the rich behavior we observe in nature is a consequence of the structure of the system rather than of the complexity of the underlying rules. From this perspective, the dynamic behavior of single-species populations is examined and an elementary feedback model of the population system is developed. This single-species model is refined and generalized by examining the mechanisms of population regulation.

Download or read book Progress in Ecological Stoichiometry written by Dedmer B. Van de Waal and published by Frontiers Media SA. This book was released on 2018 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological stoichiometry concerns the way that the elemental composition of organisms shapes their ecology. It deals with the balance or imbalance of elemental ratios and how that affects organism growth, nutrient cycling, and the interactions with the biotic and abiotic worlds. The elemental composition of organisms is a set of constraints through which all the Earth’s biogeochemical cycles must pass. All organisms consume nutrients and acquire compounds from the environment proportional to their needs. Organismal elemental needs are determined in turn by the energy required to live and grow, the physical and chemical constraints of their environment, and their requirements for relatively large polymeric biomolecules such as RNA, DNA, lipids, and proteins, as well as for structural needs including stems, bones, shells, etc. These materials together constitute most of the biomass of living organisms. Although there may be little variability in elemental ratios of many of these biomolecules, changing the proportions of different biomolecules can have important effects on organismal elemental composition. Consequently, the variation in elemental composition both within and across organisms can be tremendous, which has important implications for Earth’s biogeochemical cycles. It has been over a decade since the publication of Sterner and Elser’s book, Ecological Stoichiometry (2002). In the intervening years, hundreds of papers on stoichiometric topics ranging from evolution and regulation of nutrient content in organisms, to the role of stoichiometry in populations, communities, ecosystems and global biogeochemical dynamics have been published. Here, we present a collection of contributions from the broad scientific community to highlight recent insights in the field of Ecological Stoichiometry.

Download or read book Population Ecology of Individuals MPB 25 Volume 25 written by Adam Lomnicki and published by Princeton University Press. This book was released on 2020-03-31 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Wildlife Population Growth Rates written by R. M. Sibly and published by Cambridge University Press. This book was released on 2003-08-07 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: What determines where a species lives? And what determines its abundance? This book takes a fresh approach to some of the classic questions in ecology. Despite great progress in the twentieth century much more remains to be done before we can provide full answers to these questions. The methods described and deployed in this book point the way forward. The core message of the book is that the key insights come from understanding what determines population growth rate, and that application of this approach will make ecology a more predictive science. Topics covered include population regulation, density-dependence, the ecological niche, resource and interference competition, habitat fragmentation and the ecological effects of environmental stress, together with applications to conservation biology, wildlife management, human demography and ecotoxicology. After a substantial introduction by the editors the book brings together contributions from leading scientists from Australia, New Zealand, North America, Europe and the U.K.

Download or read book Behavioural and Ecological Consequences of Urban Life in Birds written by Caroline Isaksson and published by Frontiers Media SA. This book was released on 2018-06-19 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanization is next to global warming the largest threat to biodiversity. Indeed, it is becoming increasingly evident that many bird species get locally extinct as a result of urban development. However, many bird species benefit from urbanization, especially through the abundance of human-provided resources, and increase in abundance and densities. These birds are intriguing to study in relation to its resilience and adaption to urban environments, but also in relation to its susceptibility and the potential costs of urban life. This Research Topic consisting of 30 articles (one review, two meta-analyzes and 27 original data papers) provides insights into species and population responses to urbanization through diverse lenses, including biogeography, community ecology, behaviour, life history evolution, and physiology.
