This book was released on 1993 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of coniferous afforestation on rove beetles (Coleoptera, Staphylinidae) was investigated in Kielder Forest in 1988 by pitfall and turf sampling in plantations of various age and in unplanted sites. Tree planting decreased habitat availability for most beetles, but provided new habitat for forest species. The greatest abundance, species richness and diversity occurred in non-afforested sites. Site ordination demonstrated an upland group on acid soils and a lowland group on mineral soils, with wet and dry components; species ordination was similar. A central forest group was due to both forest species and original species being maintained. Similarly, classification separated closed-canopy forest sites with little ground vegetation from the remainder. Afforestation had increased habitat diversity by adding trees, rides and roads to the original habitats, but diversity per unit area had decreased Forest managers should aim to increase staphylinid diversity 'by design', particularly by varying tree species and age class so as to develop greater biological and structural diversity. Habitat diversity could further be enhanced by conserving representative areas of former land use, such as farm fields, river banks and open moorland; active management might be necessary to sustain these. Staphylinid species are favoured by forest edge habitats, so would gain from the integration of small habitat units within plantations, resulting in a beneficial 'knock-on' effect by being food for birds and small mammals.
Download or read book The Forests Handbook Volume 1 written by Julian Evans and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The future of the world's forests is at the forefront of environmental debate. Rising concerns over the effects of deforestation and climate change are highlighting the need both to conserve and manage existing forests and woodland through sustainable forestry practices. The Forests Handbook, written by an international team of both scientists and practitioners, presents an integrated approach to forests and forestry, applying our present understanding of forest science to management practices, as a basis for achieving sustainability. Volume One presents an overview of the world's forests; their locations and what they are like, the science of how they operate as complex ecosystems and how they interact with their environment. Volume Two applies this science to reality; it focuses on forestry interventions and their impact, the principles governing how to protect forests and on how we can better harness the enormous benefits forests offer. Case studies are drawn from several different countries and are used to illustrate the key points. Development specialists, forest managers and those involved with land and land-use will find this handbook a valuable and comprehensive overview of forest science and forestry practice. Researchers and students of forestry, biology, ecology and geography will find it equally accessible and useful.
Download or read book Beetles in Conservation written by T. R. New and published by John Wiley & Sons. This book was released on 2010-02-22 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beetles, the most diverse group of insects, are often abundant in terrestrial and freshwater ecosystems. Many species are under threat from human changes to natural environments, and some are valuable tools in conservation, because they respond rapidly to changes that occur. Knowledge of these responses, of both abundance and composition of assemblages, enable use of some beetles to monitor environmental changes. Beetles impinge on humanity on many ways: as cultural objects, desirable collectables, major pests and competitors for resources need by people, as beneficial consumers of other pests, and by ensuring the continuity of vital ecological processes. This book is the first major global overview of the importance of conservation of beetles, and brings together much hitherto scattered information to demonstrate the needs for conservation, and how it may be approached. It is a source of value to students, research workers, conservation biologists and ecosystem managers as an introduction to the richness and importance of this predominant component of invertebrate life.
Download or read book Tropical Forest Remnants written by William F. Laurance and published by University of Chicago Press. This book was released on 1997-06-21 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live in an increasingly fragmented world, with islands of natural habitat cast adrift in a sea of cleared, burned, logged, polluted, and otherwise altered lands. Nowhere are fragmentation and its devastating effects more evident than in the tropical forests. By the year 2000, more than half of these forests will have been cut, causing increased soil erosion, watershed destabilization, climate degradation, and extinction of as many as 600,000 species. Tropical Forest Remnants provides the best information available to help us understand, manage, and conserve the remaining fragments. Covering geographic areas from Southeast Asia and Australia to Madagascar and the New World, this volume summarizes what is known about the ecology, management, restoration, socioeconomics, and conservation of fragmented forests. Thirty-three papers present results of recent research as well as updates from decades-long projects in progress. Two final chapters synthesize the state of research on tropical forest fragmentation and identify key priorities for future work.
Download or read book Forests and Insects written by Allan D. Watt and published by Springer Science & Business Media. This book was released on 1997-09-30 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the full breadth of forest entomology. It combines the work of forest entomologists working on the impact and management of forest pests with those involved in diversity assessment and conservation of insects in forests. Forests and Insects demonstrates that both these disciplines demand an understanding of population and community biology. The book covers such topics as colonization of trees by insects, population dynamics of forest insects, insect natural enemies, the effects of climate change and pollution on forest pests, spatial variation in the abundance of insects,the mineralization of carbon by termites, the impact of herbivorous insects, and the conservation of forest insect diversity, including the effects of forest fragmentation and deforestation. This Royal Entomological Society Symposium volume will be of great interest to all agricultural and forest entomologists, population and community biologists, pest management specialists and anyone concerned with the conservation of forest biodiversity.

Book excerpt: New taxonomic, distribution and habitat data are presented for Canadian species of the family Staphylinidae (Coleoptera). Distributional records are presented mostly from New Brunswick, Ontario and Yukon Territory. For New Brunswick, 186 new provincial records, 11 new records for Canada, and 10 new records of adventive species are provided. For Ontario, 47 new provincial records and 25 new Canadian records are provided, and 5 species are described as new to science. For Yukon Territory, 20 new territorial records and 1 new Canadian record are provided and 9 species are described as new to science. A total of 253 new provincial/territorial records, 37 new Canadian records, and 14 species new to science are treated in this volume. Lectotypes are designated for several species and seven synonyms are proposed. All new species and many species representing new distributional records are illustrated by color habitus images and black and white images of the genital structures. This volume on Canadian rove beetle biodiversity contributes new taxonomic research and important baseline data, and significantly updates the known staphylinid faunas of New Brunswick, Ontario, Yukon Territory, and Canada.

Download or read book Canopy Arthropods written by Nigel E. Stork and published by Springer. This book was released on 1997 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: As forests are cut down, altered and fragmented, the communities of organisms associated with them are also affected. Predictions of global species extinction rates based on forest loss range 1% to 10% each decade. Because arthropods comprise the largest component of animal species richness, it is inevitable that many arthropod species will become extinct. Millions of these species are thought to live in the forest canopy. During the last twenty years recognition of the importance of canopy arthropods to global biodiversity and the crucial roles arthropods play in forests has led to a revolution in the study and understanding of the arthropod community structure in the forest canopy. Recent advances have been greatly aided by the development of improved sampling techniques and new methods of access to the forest canopy. Canopy Arthropods brings together for the first time a wide range of the most recent studies of arthropods living in forest canopies and comes from a truly international team of contributors.
