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 Introduction to Forest and Shade Tree Insects written by Bozzano G Luisa and published by Elsevier. This book was released on 2012-12-02 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehenisive text approaches the subject from an ecological/evolutionary biological perspective. The assumption is that one cannot study forest insects without understanding the dynamics of the relationship between an insect and its host plant. This relationship includes knowing what factors control forest insect populations such as food, food quality, tree vigor, host selection, and symbiotic relationships. The authors also discuss tree-injuring insects from the perspective of their influence on tree physiology and growth as well as economic and commercial effects. The book represents a "modern" approach to the topic of forest and shade tree insects; is well-illustrated; and includes a comprehensive primary reference list.

Download or read book Killing Bugs for Business and Beauty written by Mark Kuhlberg and published by University of Toronto Press. This book was released on 2022-03-31 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Killing Bugs for Business and Beauty examines the beginning of Canada’s aerial war against forest insects and how a tiny handful of officials came to lead the world with a made-in-Canada solution to the problem. Shedding light on a largely forgotten chapter in Canadian environmental history, Mark Kuhlberg explores the theme of nature and its agency. The book highlights the shared impulses that often drove both the harvesters and the preservers of trees, and the acute dangers inherent in allowing emotional appeals instead of logic to drive environmental policy-making. It addresses both inter-governmental and intra-governmental relations, as well as pressure politics and lobbying. Including fascinating tales from Cape Breton Island, Muskoka, and Stanley Park, Killing Bugs for Business and Beauty clearly demonstrates how class, region, and commercial interest intersected to determine the location and timing of aerial bombings. At the core of this book about killing bugs is a story, infused with innovation and heroism, of the various conflicts that complicate how we worship wilderness.

Download or read book Foundations of Ecological Resilience written by Lance H. Gunderson and published by Island Press. This book was released on 2012-07-16 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological resilience provides a theoretical foundation for understanding how complex systems adapt to and recover from localized disturbances like hurricanes, fires, pest outbreaks, and floods, as well as large-scale perturbations such as climate change. Ecologists have developed resilience theory over the past three decades in an effort to explain surprising and nonlinear dynamics of complex adaptive systems. Resilience theory is especially important to environmental scientists for its role in underpinning adaptive management approaches to ecosystem and resource management. Foundations of Ecological Resilience is a collection of the most important articles on the subject of ecological resilience—those writings that have defined and developed basic concepts in the field and help explain its importance and meaning for scientists and researchers. The book’s three sections cover articles that have shaped or defined the concepts and theories of resilience, including key papers that broke new conceptual ground and contributed novel ideas to the field; examples that demonstrate ecological resilience in a range of ecosystems; and articles that present practical methods for understanding and managing nonlinear ecosystem dynamics. Foundations of Ecological Resilience is an important contribution to our collective understanding of resilience and an invaluable resource for students and scholars in ecology, wildlife ecology, conservation biology, sustainability, environmental science, public policy, and related fields.
