Available in PDF, EPUB and Kindle. Book excerpt: Genes in the Environment presents the recent research in the exciting and rapidly developing field of molecular, genetic and modelling techniques. These techniques, central to ecology, provide valuable new tools for addressing complex ecological questions and considerable insights into our understanding of the dynamics of populations and communities. A diver se range of topics is covered, including community dynamics in soils and water, gene flow and spatial dynamics, and the evolution of the pathogenic and symbiotic relationships. Organisms studied range from bacteria, viruses and fungi to insects, plants and fish.
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 Ecological Methods in Forest Pest Management written by David Wainhouse and published by OUP Oxford. This book was released on 2004-12-16 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the management of forest pests. It focuses predominantly on insect pests, but many examples relate to fungal pathogens, some of which are vectored by forest insects. The central theme of the book is the development of Integrated Pest Management (IPM), the main impetus for which comes from the need to use environmentally sensitive methods of control appropriate to both semi-natural and plantation forests. Such forests are likely to be managed not only for timber production but also for recreation and to enhance biodiversity. An introductory chapter describes how forests have been transformed by exploitation and management and how altering the composition and distribution of forests can contribute to pest problems. Subsequent chapters focus on the 'techniques' of management and control that contribute to IPM, considering in turn plant health, risk-rating, silviculture, tree resistance, biological control, microbial control and semiochemicals. By focussing on these important elements of management, the aim is to provide a critical analysis of the theory and practice of each one in relation to key aspects of both pest and forest ecology. The final chapter on IPM brings together elements of the previous chapters, discussing them in the context of the economic and environmental impact of pests, the economics of control, and the role of decision support systems. Detailed case studies are provided and future developments in IPM discussed in relation to sustainability, conservation and the potential impact of climate change.
Download or read book Ecological and Economic Entomology written by Brian E. Freeman and published by CABI. This book was released on 2020-11-11 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological and Economic Entomology is a comprehensive advanced text covering all aspects of the role of insects in natural ecosystems and their impacts on human activity. The book is divided into two sections. The first section begins with an outline of the structure, classification and importance of insects, followed by the geographical aspects of plant distribution and the complex defences plants marshal against herbivorous insects. Insect pests affecting plant roots, stem, leaf, and reproductive systems are covered in a comprehensive review. This section also covers insects that are important in medical and veterinary science, paying particular attention to those that transmit pathogens. The section concludes with the beneficial aspects of insects, especially their use in biological control, but also as soil formers and their importance in forensic science.

This book was released on 2007-10-04 with total page 852 pages. Available in PDF, EPUB and Kindle. Book excerpt: The basic tools include chapters on the theory and practice of application of microbial control agents (MCAs) (Section I), statistical considerations in the design of experiments (Section II), and three chapters on application equipment and strategies (Section III). Section IV includes individual chapters on the major pathogen groups (virus, bacteria, microsporidia, fungi, and nematodes) and special considerations for their evaluation under field conditions. This section sets the stage for subsequent chapters on the impact of naturally occurring and introduced exotic pathogens and inundative application of MCAs. Twenty-three chapters on the application and evaluation of MCAs in a wide variety of agricultural, forest, domestic and aquatic habitats comprise Section VII of the Field Manual. In addition to insect pests, the inclusion of mites and slugs broadens the scope of the book.

Book excerpt: Molecular techniques in the study of gene flow, genetics, phenomics, adaptation, etc., of bacteria and viruses are most successful and have enabled scientists all over the world to understand and bring to the fore underlying causes of numerous diseases as well as harmful and beneficial effects of the activities of these microorganisms. Such study also helps through genetic variation and adaptive variance to mitigate or enhance the effects of such activities. "Gene Flow and Molecular Biology : Ecological Perspective" present study of microorganisms--bacteria and viruses--through identification of study area or problem, specific species concerned, genetic variation and adaptation and outcomes, using molecular techniques. Looking into effects of genetic variation and concept of gene flow, numerous deleterious diseases are investigated along with beneficial use of molecular techniques. Each chapter represents study of individual aspect of these microorganisms in specific situation investigated by expert team of researchers.
