Available in PDF, EPUB and Kindle. Book excerpt: If it is still true that more than 80% of the ornithologists in North America are primarily interested or engaged in ecological studies on birds (J. R. King and W. J. Bock, Final Report of the Workshop on a National Plan For Ornithology, 1978), then Volume 3 of Current Orni thology is preadapted for their consideration. All but one article in this volume are somehow concerned with the ecological aspects of the bi ology of birds. Variation in the scope of topical coverage is relatively broad, and includes conservation, reproduction, behavior, community structure, and evolutionary ecology. Three reviews concern the pervasive effects of man and industry on various bird populations of the world. Risebrough provides a de tailed description of the relationships between pesticides and bird pop ulations. Morrison ass es ses aspects of bird population numbers as in dicators of environmental change, and Temple outlines current research on endangered species. The broad spectrum of reproductive ecology of birds is variously treated in this volume. Jehl and Murray explore sexual selection and some of the resulting complexities in the evolution of sexual size di morphism, primarily in shorebirds. Lawton and Lawton are concerned with the relationships between social behavior and breeding systems in which variation is found in the age at which reproduction is first undertaken. Oring examines the wide-ranging variation in polyandrous breeding systems in birds, while Rohwer is concerned with adoption versus infanticide in birds, and their relationships to reproductive fit ness.

Available in PDF, EPUB and Kindle. Book excerpt: "This annotated bibliography contains over 700 references which deal with: (1) effects, direct and indirect, of forest management practices on nongame forest birds, covering such topics as logging, cut types, rotation periods, thinning, site preparation, plantations, pesticides, herbicides, burning and regeneration: (2) forest bird-habitat relationships in both natural and sites disturbed by forestry operations or other practices which would produce similar situations; (3) factors affecting species diversity and biogeography distributions; (4) the role of birds in the forest ecosystem; and (5) management and conservation considerations for nongame forest birds, and sorne related techniques. The emphasis was placed on migratory songbirds in the boreal forest area. However, since few studies have investigated the effects of forestry practices on this category of birds in the boreal region, information was included for a variety of habitat types from aIl over North America, and a few from other regions. It was hoped that the findings and management considerations in these papers would provide usefuI information, and that some of the trends observed could be applied to the boreal region"--Abstract, p. iii.

Book excerpt: Cutting across traditional subject boundaries, Principles of Ecotoxicology, Fourth Edition gives readers an integrated view of ecotoxicology, from molecules to ecosystems. This new edition of a bestselling textbook continues to emphasize principles rather than practice, providing the interdisciplinary perspective and grounding required for research. Organized into three sections, the book first describes the molecular structures, properties, and environmental fate of pollutants. It then deals with the effects of pollutants on living organisms at the molecular, cellular, and individual levels. Moving into population biology and population genetics, the third part of the book addresses a question of great interest to ecologists: What effects do pollutants have at the levels of population, community, and the whole ecosystem? The book also looks at how ecotoxicology is used in the biomonitoring of environmental pollution, the investigation of pollution problems, the conducting of field trials, the study of the development of resistance, and the growing area of environmental risk assessments. Throughout, examples and case studies illustrate the principles. This updated fourth edition includes new material on nanoparticle pollution, bioaccumulation, biomarkers, and chemical warfare in nature, as well as a new chapter on the future directions of ecotoxicology. A concise textbook that will also appeal to practicing ecotoxicologists, it provides a solid basis for understanding what happens to chemicals in the real world, where they go, how they ultimately degrade, and how they affect the individuals and populations that encounter them. What's New in This Edition Revised and updated material throughout A chapter on future directions of ecotoxicology New material on nanoparticle pollution and chemical warfare in nature Expanded coverage of bioaccumulation, biomarkers, and risk assessment for affected populations More case studies, many from the United States Discussion of neurotoxic and behavioral effects of pollutants Recent research on the decline of vultures and effects of neonicotinoids on bees Organic Pollutants: An Ecotoxicological Perspective, Second Edition(CRC Press, 2008), a companion volume to this book, covers the mechanistic aspects of ecotoxicology in more depth.
Download or read book Environmental Effects of Fenitrothion Use in Forestry written by W. R. Ernst and published by [Dartmouth, N.S.] : Environment Canada, Conservation and Protection, Atlantic Region. This book was released on 1989 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fenitrothion has been used in forest protection in the Atlantic Region since its first experimental application in 1965, and has been monitored for its effects from the beginning. This report presents the results of separate technical reviews undertaken on the effects of fenitrothion on pollinators and pollination, forest songbirds, and aquatic fauna. The reviews are essentially distillations of available literature, with the exception of the songbird review which also incorporated previously unpublished data and a re-analysis of earlier published information. Sources accessed include papers published in the primary literature as well as published and unpublished government reports. Recommendations are included.

Book excerpt: A Passion for Wildlife chronicles the history of the Canadian Wildlife Service and the evolution of Canadian wildlife policy over its first half century. It presents the exploits and accomplishments of a group of men and women whose dedication to the ideals of science, conservation, and a shared vision of Canada as a country that treasures its natural heritage has earned them the respect of their profession around the world. Drawing on interviews and anecdotes, personal correspondence, and the published record, the book addresses topics as varied as game law enforcement, field biology, habitat conservation, environmental education, toxicology, federal-provincial relations, and international diplomacy. Accessible to anyone interested in nature, it will appeal particularly to wildlife managers, scientists, naturalists, as well as students of biology, wildlife technology, and environmental studies.
Download or read book Environmental Ecology written by Bill Freedman and published by Elsevier. This book was released on 2013-09-25 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Ecology: The Impacts of Pollution and Other Stresses on Ecosystem Structure and Function deals with environmental studies on the ecological impacts of anthropogenic stresses. The book discusses more particularly the ways that anthropogenic or natural influences affect the quality of the inorganic and biotic components of the biosphere, as well as the human environment. The text discusses the sources of air pollution, the different toxic elements (naturally occurring contamination or anthropogenic sources), and acidifying substances or "acid rain." The author also cites several studies that deal with the reclamation of acidified bodies of water. Another topic the author addresses is declining forest areas; he then cites several case studies of this occurrence, such as those by Fowells, 1965; Hepting, 1971; and Auclair, 1987. The text also investigates the ecological effects of oil pollution caused during the refining process and transportation. The author then examines the general response patterns to ecological stress. The text is intended for advanced students of environmental ecology and environmental science, as well as for ecologists, environmentalists, and urban planners and officials.

Download or read book Animal Biomarkers as Pollution Indicators written by David B. Peakall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology is a relatively new scientific discipline. Indeed, it might be argued that it is only during the last 5-10 years that it has come to merit being regarded as a true science, rather than a collection of procedures for protecting the environment through management and monitoring of pollutant discharges into the environment. The term 'ecotoxicology' was first coined in the late sixties by Prof. Truhaut, a toxicologist who had the vision to recognize the importance of investigating the fate and effects of chemicals in ecosystems. At that time, ecotoxicology was considered a sub-discipline of medical toxicology. Subsequently, several attempts have been made to portray ecotoxicology in a more realistic light. Notably, both F. Moriarty (1988) and F. Ramade (1987) emphasized in their books the broad basis of ecotoxicology, encompassing chemical and radiation effects on all components of ecosystems. In doing so, they and others have shifted concern from direct chemical toxicity to man, to the far more subtle effects that pollutant chemicals exert on natural biota. Such effects potentially threaten the existence of all life on Earth. Although I have identified the sixties as the era when ecotoxicology was first conceived as a coherent subject area, it is important to acknowledge that studies that would now be regarded as ecotoxicological are much older. Wherever people's ingenuity has led them to change the face of nature significantly, it has not escaped them that a number of biological con sequences, often unfavourable, ensue.
