Book excerpt: Ecologists will find in this journal the essence of current ecology research across a wide range of disciplines, reflecting recent advances in light of growing evidence regarding global environmental change and destruction. Ecology Abstracts focuses on how organisms of all kinds - microbes, plants, and animals - interact with their environments and with other organisms. Included are relevant papers on evolutionary biology, economics, and systems analysis as they relate to ecosystems or the environment. With coverage ranging from habitats to food chains, from erosion to land reclamation, the journal provides an important cross-section of current findings in target research areas. Detailed information on resource and ecosystems management and modeling contributes to the journal's practical value, as does material on the impact of climate, water resources, soil, and man or growing environmental problems such as depletion, erosion, and pollution all topics which are covered in depth. Comprehensive, yet carefully focused coverage makes this an essential resource for scientists concerned with preserving the environment.

Download or read book Biocontrol Based Integrated Management of Oilseed Rape Pests written by Ingrid H. Williams and published by Springer Science & Business Media. This book was released on 2010-06-16 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oilseed rape is a major arable crop in both Europe and North America. It is attacked by unique complexes of insect pests still largely controlled through the application of chemical insecticides. Crop management systems for the future must combine sustainability with environmental acceptability to satisfy both social and economic demands. This book, in its 17 chapters each led by a world expert, reviews research progress towards developing integrated pest management systems for the crop that enhance conservation biocontrol. This approach is particularly timely because of the development in Europe of insecticide resistance in the pollen beetle, a major pest of the crop. The past decade has seen considerable progress in our knowledge of the parasitoids and predators that contribute to biocontrol, of their distribution patterns, and their behavioural ecology, both within and without the crop. There is potential for natural enemy conservation through modification of within-field crop husbandry practices, as well as, on the landscape scale, through habitat manipulation to encourage vegetational diversity. This book will prove invaluable as a text for researchers, university teachers, graduate scientists, extension workers and growers involved in integrated pest management.
Download or read book Whooping Cranes Biology and Conservation written by and published by Academic Press. This book was released on 2018-09-04 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whooping Cranes: Biology and Conservation covers one of the most endangered birds in North America, and the subject of intense research and highly visible conservation activity. The volume summarizes current biological information on Whooping Cranes and provides the basis for future research necessary for conservation of this species. This edited volume concentrates on work completed in the past 20 years in the areas of population biology, behavior and social structure, habitat use, disease and health, captive breeding, and Whooping Crane conservation. Much of the information presented comes from the study and management of remnant and reintroduced populations of Whooping Cranes in the field; some information is from experimentation and breeding of captive Whooping Cranes. Whooping Cranes: Biology and Conservation seeks to inform and galvanize action dedicated to meeting the challenges faced by Whooping Crane managers and conservationists. Thus, it describes one model of endangered species conservation and restoration that will interest a wide audience: professionals that work on cranes; researchers in the fields of small population biology, endangered species, and avian ecology; wildlife veterinarians and those involved in avian husbandry; administrators of management agencies or conservation organizations; conservationists in other fields; teachers of conservation biology or ornithology and their students; and the educated general public. - Presents a comprehensive treatment of the biology and ecology of Whooping Cranes, including biology of both remnant and reintroduced populations of Whooping Cranes - Describes efforts over the past 45 years on conservation and the challenges of reintroducing an endangered species - Includes chapters from a variety of disciplinary and scale perspectives, ranging from evolution, to population ecology, behavior, habitat use, large landscape conservation, conflict, and conservation efforts - Features contributions that are readable, yet technically complete and fully referenced - Provides an example of partnership and collegial action that integrates information produced by scientific research and operational wildlife management - Edited and written by the leading Whooping Crane scholars and practitioners focused on this high-profile species of conservation concern

Download or read book Physical Control Methods in Plant Protection written by Charles Vincent and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jointly published with INRA, Paris. Pesticide resistance is becoming more frequent and widespread with more than 500 insect species known to have become resistant to synthetic insecticides. On the other hand, consumers increasingly demand agricultural products without any pesticide residues. This book, for the first time, shows the alternative: solely physical methods for plant protection by means of thermal, electromagnetic, mechanical and vacuum processes. A glossary rounds up this extremely valuable book.

Available in PDF, EPUB and Kindle. Book excerpt: Over de invloed van de atmosfeer op een groot aantal kleine organismen die met de lucht vervoerd worden. Velen hiervan zijn schadelijk voor de mens, voor landbouwgewassen en voor de veestapel. Het is een boek voor biologen waarin praktische en komplexe problemen over ongedierte en ziekten worden behandeld, maar ook de ekologie in het algemeen, vanuit de meteorologie. Het kombineren van kennis over weerkunde en biologie van lucht kan leiden tot verbetering in het voorspellen, registreren en bestrijden van schadelijke organismen (met de wind meegevoerd) en ziekten

Book excerpt: Published in 1955 by the University of Oklahoma Press, this is the classic study of the extinction of the passenger pigeon. The passenger pigeon, once probably the most numerous bird on the planet, made its home in the billion or so acres of primary forest that once covered North America east of the Rocky Mountains. Their flocks, a mile wide and up to 300 miles long, were so dense that they darkened the sky for hours and days as the flock passed overhead. Population estimates from the 19th century ranged from 1 billion to close to 4 billion birds. Total populations may have reached 5 billion birds and comprised up to 40% of the total number of birds in North America. This may be the only species for which the exact time of extinction is known. No appreciable decline in the numbers was noted until the late 1870s but, thereafter, their destruction took only twenty-five years. The immense roosting and nesting colonies invited over-hunting. Tens of thousands of individuals were harvested daily from nesting colonies, and shipped to markets in the east. Modern technology hastened the demise of the passenger pigeon. With the coming of the telegraph, the locations of flocks could be ascertained, and the birds relentlessly pursued. The last bird died in 1914 at the Cincinnati Zoological Garden before any competent ornithologists could write an account of the species. A. W. Schorger reconstructed the life history of the passenger pigeon. Through painstaking research, he examined every aspect of the species -- behavioral characteristics, feeding methods, traveling and roosting habits, nesting - and the various stages of the species encounter with man, from utilization by the Native American to extinction at the hands of white settlers.
