Download or read book Dynamics of Forest Insect Populations written by Alan A. Berryman and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance and scarcity has a rhythm of its own, and the Cures are applied just when the plague of insects is going to abate through its own loss of momentum. -Abridged, with insects in place of voles, from C. Elton, 1924, Voles, Mice and Lemmings, with permission of Oxford University Press This book is an enquiry into the "natural rhythms" of insect abundance in forested ecosystems and into the forces that give rise to these rhythms. Forests form unique environ ments for such studies because one can find them growing under relatively natural (pri meval) conditions as well as under the domination of human actions. Also, the slow growth and turnover rates of forested ecosystems enable us to investigate insect popula tion dynamics in a plant environment that remains relatively constant or changes only slowly, this in contrast to agricultural systems, where change is often drastic and frequent.
Download or read book The Lives of Moths written by Andrei Sourakov and published by Princeton University Press. This book was released on 2022-04-26 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: A richly illustrated look at the natural history of moths Moths are among the most underappreciated insects on the planet, yet they make up the majority of some 180,000 known species of Lepidoptera. Filled with striking images, The Lives of Moths looks at the remarkable world of these amazing and beautiful creatures. While butterflies may get more press than moths, Andrei Sourakov and Rachel Warren Chadd reveal that the lopsided attention is unjust. Moths evolved long before butterflies, and their importance cannot be overestimated. From the tiniest leaf miners to exotic hawk moths that are two hundred to three hundred times larger, these creatures are often crucial pollinators of flowers, including many that bloom at night or in twilight. The authors show that moths and their larvae are the main food source for thousands of animal species, and interact with other insect, plant, and vertebrate communities in ecosystems around the world, from tropical forests and alpine meadows to deserts and wetlands. The authors also explore such topics as evolution, life cycles, methods of communication, and links to humans. A feast of remarkable facts and details, The Lives of Moths will appeal to insect lovers everywhere.

Download or read book Ecophysiology of Coniferous Forests written by William K. Smith and published by Academic Press. This book was released on 2013-10-22 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conifers--pine, fir, and spruce trees--are dominant species in forests around the world. This book focuses on the physiology of conifers and how these physiological systems operate. Special consideration is devoted to the means by which ecophysiological processes influence organismal function and distribution. Chapters focus on the genetics of conifers, their geographic distribution and the factors that influence this distribution, the impact of insect herbivory on ecophysiological parameters, the effects of air pollution, and the potential impact that global climatic changes will have upon conifers. Because of the growing realization that forests have a crucial role to play in global environmental health, this book will appeal to a developing union of ecologists, physiologists and more theoretically minded foresters.
Download or read book The Silviculture of Trees Used in British Forestry 3rd Edition written by Peter S Savill and published by CABI. This book was released on 2019-04-12 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: British woodlands and forests are often located on sites and in regions that are marginal for agriculture; many are at high elevations and exposed, with short growing seasons. Wherever forests are located, site and climatic conditions must dictate species choice in forest management. This book provides a detailed guide to the biological suitability of different sites and soils for all important native trees and the most extensively used exotics. Apart from physical difficulties such as steepness and stoniness, forest soils also frequently have problems associated with them. They can be waterlogged or drought-prone, suffer from extremes of acidity or alkalinity, or have compacted layers. The book provides information on species' suitability for different purposes. It includes details of species' origin and introduction (where applicable), as well as their climatic and soil requirements and other silvicultural characteristics. Information about provenance, yield and timber is also provided. Fully updated throughout, this 3rd edition puts more emphasis on species suitable for changing climatic conditions, with accounts of several species that may become more prominent in British forests: including several silver firs, hickories, eucalypts, spruces, poplars and wingnuts. The book concludes with simple keys for identifying the trees most likely to be encountered in British forests. It is an essential resource for students, researchers and forestry professionals.

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 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.
