Available in PDF, EPUB and Kindle. Book excerpt: As Ecology teachers ourselves we have become increasingly aware of the lack of a single comprehensive textbook of Ecvlogy which we can recommend unreservedly to our students. While general, review texts are readily available in other fields, recent publications in Ecology have tended for the most part to be small, specialised works on single aspects of the subject. Such general texts as are available are often rather too detailed and, in addition, tend to be somewhat biased towards one aspect of the discipline or another and are thus not truly balanced syntheses of current knowledge. Ecology is, in addition, a rapidly developing subject: new information is being gathered all the time on a variety of key questions; new approaches and techniques open up whole new areas of research and establish new principles. Already things have changed radically since the early '70s and we feel there is a need for an up to date student text that will include some of this newer material. We have tried, therefore, to create a text that will review all the major principles and tenets within the whole field of Ecology, presenting the generally accepted theories and fundamentals and reviewing carefully the evidence on which such principles have been founded. While recent developments in ecological thought are emphasised, we hope that these will not dominate the material to the extent where the older-established principles are ignored or overlooked.
Download or read book Bark and Wood Boring Insects in Living Trees in Europe a Synthesis written by François Lieutier and published by Springer Science & Business Media. This book was released on 2007-08-24 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time, a synthesis on the research work done in Europe on all Bark And Wood Boring Insects In Living Trees (BAWBILT) is presented. As final product of a four-year research project gathering together 100 scientists from 24 countries, the book is the fruit of a real collective synthesis in which all European specialists have participated. It reviews and comments on all the European literature, while considering the biological (trees, insects, associated organisms, and their relationships) and forest management aspects. However, although focused on the European forest, it also compares the available information and interpretations to those concerning similar species in other continents. It ends with propositions of research priorities for Europe. The book is directed to all scientists and students concerned with forest entomology and ecology, as well as to forest managers and all scientific public interested in forest biology.
Download or read book Habitat Structure written by S.S. Bell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: We conceived the idea for this book after teaching a graduate seminar on 'Habitat Complexity' at The University of South Florida. Discussions during the seminar led us to conclude that similar goals were to be found in studies of the topic that spanned the breadth of ecological research. Yet, the exact meaning of 'habitat structure', and the way in which it was measured, seemed to differ widely among subdisciplines. Our own research, which involves several sorts of ecology, convinced us that the differences among subdisciplines were indeed real ones, and that they did inhibit communica tion. We decided that interchange of ideas among researchers working in marine ecology, plant-animal interactions, physiological ecology, and other more-or-less independent fields would be worthwhile, in that it might lead to useful generalizations about 'habitat structure'. To foster this interchange of ideas. we organized a symposium to attract researchers working with a wide variety of organisms living in many habitats, but united in their interest in the topic of 'habitat structure'. The symposium was held at The University of South Florida's Chinsegut Hill Conference Center, in May. 1988. We asked participants to think about 'habitat structure' in new ways; to synthesize important, but fragmented, information; and. perhaps. to consider ways of translating ideas across systems. The chapters contained in this book reflect the participants' attempts to do so. The book is divided into four parts, by major themes that we have found useful categorizations.
Download or read book Processionary Moths and Climate Change An Update written by Alain Roques and published by Springer. This book was released on 2014-10-10 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of its peculiar biology, its negative impacts on forestry, and its urticating larvae affecting human and animal health, pine processionary moth has largely been studied in many European countries during the last century. However, knowledge remained scattered and no synthesis has ever been published. Since the IPCC retained the moth as one of the two insect indicators of climate change because of its expansion with warming up, filling this gap became increasingly important. Led by INRA, this book associates 101 authors from 22 countries of Europe, Minor Asia and North Africa, combining all the concerned research fields (entomology, ecology, genetics, mathematical modelling, medical and veterinary science, pest management) in a multidisciplinary approach to understand and model the processes underlying past, present and future moth expansion and to propose adapted management methods. Besides, the major biological patterns of the related processionary species are also detailed.

Download or read book A Eutrophic Lake written by Thomas D. Brock and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Mendota has often been called "the most studied lake in the world. " Beginning in the "classic" period of limnology in the late 19th century and continuing through the present time, this lake has been the subject of a wide variety of studies. Although many of these studies have been published in accessible journals, a significant number have appeared in local monographs and reports, ephemeral documents, or poorly distributed journals. To date, there has been no attempt at a synthetic treatment ofthe vast amount of work that has been published. One intent of the present book is to present a com prehensive compilation of the major early studies on Lake Mendota and to examine how they impinge on important present-day biological questions. In addition, this book presents a summary of field and laboratory work carried out in my own laboratory over a period of about 6 years and shows where correlations with earlier work exist. The book should be ofinterest to limnologists desiring a ready reference to data and published papers on this important lake, to biogeochemists, ocean ographers, and low-temperature geochemists interested in lakes as model sys tems for global processes, and to lake managers interested in understanding short-term and long-term changes in lake systems. Although the major thrust ofthe present book is ecologicaland environmental, sufficient background has been presented on other aspects ofLake Mendota's limnology so that the book should also be useful to nonbiologists.

Download or read book Forest Insects written by Alan A. Berryman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended as a general text for undergraduates studying the manage ment of forest insect pests. It is divided into four parts: insects, ecology, manage ment, and practice. Part I, Insects, contains two chapters. The first is intended to provide an overview of the general attributes of insects. Recognizing that it is impossible to adequately treat such a diverse and complex group of organisms in such a short space, I have attempted to highlight those insectan characteristics that make them difficult animals to combat. I have also tried to expose the insects' weak points, those attributes that make them vulnerable to manipulation by human actions. Even so, this first chapter will seem inadequate and sketchy to many of my colleagues. Ideally, this book should be used in conjunction with a laboratory manual covering insect anatomy, physiology, biology, behavior, and classifica tion in much greater depth-in fact, this is how I organize my forest entomology course. It is hoped that this first chapter will provide nonentomologists with a general feel for the insects and with a broad understanding of their strengths and weaknesses, while Chapter 2 will provide a brief overview of the diverse insect fauna that attacks the various parts of forest trees and their products.
Download or read book Viruses and Environment written by Edouard Kurstak and published by Elsevier. This book was released on 2012-12-02 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viruses and Environment contains the proceedings of the Third International Conference on Comparative Virology, held at Mont Gabriel, Quebec, Canada on May 1977. The primary focus of the conference is the ecology of viruses, that is, the interrelationships between organisms and their environment. Organized into seven parts with a total of 33 chapters, this book centers on the impact of viruses on the environment; the persistent virus infections of man, vertebrate and invertebrate animals, and plants; and the smallest disease agents, the viroids. In particular, this book describes the reservoirs of viruses, such as arthropod vectors, water, cultivated plants, and wild animals; safety considerations concerning the use of live virus vaccines; and the viral insecticides. The use of bacterial viruses in genetic engineering is also addressed. This treatise will be valuable to research workers in medical and biomedical fields; biological control; and animal and plant quarantine. It will also benefit the university teachers and graduate students.
