Download or read book Insect Populations In theory and in practice written by Jack P. Dempster and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects are by far the largest group of animals on Earth, with over a million described species, and they occupy a wide range of ecological niches - they may be herbivores, predators, parasites or decomposers. Some are of particular economic importance as pests of agriculture and forestry, as vectors of animal and human disease, or as species of interest to wildlife conservation. Thus an understanding of the processes determining their numbers is of considerable practical value. Entomologists have played a leading role in developing a theoretical basis to Population Ecology, but we still do not have adequate experimental and observational proof for many of the theoretical ideas that have been proposed. As a result, the subject has been beset with arguments for more than 50 years. This volume attempts to reconcile some of these controversies, while also reviewing the current state of our knowledge. The editors have drawn together an international list of contributors whose views reflect a range of opinions on how natural populations are stabilised. They have succeeded in producing a book that both covers the main alternative views in population theory and contains some of the best recent field studies of insect populations. This Royal Entomological Society Symposium volume will be of great interest to all entomologists and ecologists, particularly those who wish to know more about Population Dynamics.

Download or read book Coevolution of Animals and Plants written by Lawrence E. Gilbert and published by University of Texas Press. This book was released on 1980-06 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has long been recognized that plants and animals profoundly affect one another’s characteristics during the course of evolution. However, the importance of coevolution as a dynamic process involving such diverse factors as chemical communication, population structure and dynamics, energetics, and the evolution, structure, and functioning of ecosystems has been widely recognized for a comparatively short time. Coevolution represents a point of view about the structure of nature that only began to be fully explored in the late twentieth century. The papers presented here herald its emergence as an important and promising field of biological research. Coevolution of Animals and Plants is the first book to focus on the dynamic aspects of animal-plant coevolution. It covers, as broadly as possible, all the ways in which plants interact with animals. Thus, it includes discussions of leaf-feeding animals and their impact on plant evolution as well as of predator-prey relationships involving the seeds of angiosperms. Several papers deal with the most familiar aspect of mutualistic plant-animal interactions—pollination relationships. The interactions of orchids and bees, ants and plants, and butterflies and plants are discussed. One article provides a fascinating example of more indirect relationships centered around the role of carotenoids, which are produced by plants but play a fundamental part in the visual systems of both plants and animals. Coevolution of Animals and Plants provides a general conceptual framework for studies on animal-plant interaction. The papers are written from a theoretical, rather than a speculative, standpoint, stressing patterns that can be applied in a broader sense to relationships within ecosystems. Contributors to the volume include Paul Feeny, Miriam Rothschild, Christopher Smith, Brian Hocking, Lawrence Gilbert, Calaway Dodson, Herbert Baker, Bernd Heinrich, Doyle McKey, and Gordon Frankie.

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.

Download or read book Plant Ecology written by Michael J. Crawley and published by John Wiley & Sons. This book was released on 2009-06-22 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant ecology is the scientific study of the factors influencing the distribution and abundance of plants. This benchmark text, extremely well received in its first edition, shows how pattern and structure at different levels of plant organization--from ecophysiology through population dynamics to community structure and ecosystem function--are influenced by abiotic factors (eg, climate and soils) and by biotic factors (eg, competition and herbivory). Adopting a dynamic approach, this book combines descriptive text with theoretical models and experimental data. It will be invaluable reading for both student and practising ecologist alike. In this second edition, the structure of the book has been completely revised, moving from the small scale to the large scale, in keeping with contemporary teaching methods. This fresh approach allows consideration of several new and important topics such as plant secondary chemistry, herbivory, sex, and breeding systems. Additional chapters address topical applied issues in plant ecology including global warming, pollution and biodiversity.

Available in PDF, EPUB and Kindle. Book excerpt: Plant secondary metabolites (PSMs) such as terpenes and phenolic compounds are known to have numerous ecological roles, notably in defence against herbivores, pathogens and abiotic stresses and in interactions with competitors and mutualists. This book reviews recent developments in the field to provide a synthesis of the function, ecology and evolution of PSMs, revealing our increased awareness of their integrative role in connecting natural systems. It emphasises the multiple roles of secondary metabolites in mediating the interactions between organisms and their environment at a range of scales of ecological organisation, demonstrating how genes encoding for PSM biosynthetic enzymes can have effects from the cellular scale within individual plants all the way to global environmental processes. A range of recent methodological advances, including molecular, transgenic and metabolomic techniques, are illustrated and promising directions for future studies are identified, making this a valuable reference for researchers and graduate students in the field.

Book excerpt: CHOICE Highly recommended 2020 Insects are key components of life on our planet, and their presence is essential for maintaining balanced terrestrial ecosystems. Without insects humans would struggle to survive, and on a world scale food production would be severely compromised. Many plants and animals depend directly or indirectly on insects for their very survival, and this is particularly so in the case of insectivorous birds and other such creatures. The beneficial role of insects is often overlooked or misunderstood, and in farming circles their very presence on crops is often seen to be unwelcome. In reality, however, many insects are genuinely beneficial, as in the case of parasitic and predacious species. The use of chemical pesticides to control crop pests is becoming more tightly regulated and environmentally undesirable, and low-input farming, in which natural enemies of pests are encouraged to survive or increase, is becoming far more prevalent. Accordingly, Integrated Pest Management (IPM) and Integrated Pest Management (ICM) strategies are increasingly being developed, advocated and adopted. Features: Highlights information on many groups of insects and mites that act as natural enemies or biological control agents of phytophagous insects and mites, including plant pests. Profusely illustrated with high-quality colour photographs. Focuses mainly on insects and mites as natural enemies of plant pests, including parasitic and predacious species that have been accidentally or deliberately introduced in classical biological control programmes. Reviews the role of phytophagous European insects and mites in controlling or managing European plants that have become invasive weeds in other parts of the world, notably North America, Australia and New Zealand.
