Blame it on the Spruce Budworm
Author: Susan Charlotte Haley
Publisher: Wolfville, N.S. : Gaspereau Press
ISBN: 9781894031066
Category : Canada
Languages : en
Pages : 236
Book Description
Diana Cummings is from Toronto, so when she needed a quiet, slow-paced place to finish her movie script and consider her failing marriage, Nova Scotia's Rossignol Valley seemed the perfect retreat. She couldn't have been more wrong! After answering an advertisement in the local newspaper, Diana becomes the "Extraordinary Secretary" for the Prince County Woodlot Owners Association - a rag-tag gang of woodsmen and farmers embroiled in a losing battle over the government's forestry policies.

Forestry Pesticide Aerial Spraying
Author: J. J. C. Picot
Publisher: Springer Science & Business Media
ISBN: 9780792343714
Category : Nature
Languages : en
Pages : 234
Book Description
The book deals quantitatively with the generation, dispersion, and deposition of pesticide droplets on vegetation and with off-target drift of undeposited droplets. A computer simulation model of calculating dispersion, deposition, and drift is described with comparisons between calculated results and field measurement results. The model includes the effects of aircraft vortex, atmospheric turbulence, droplet evaporation, and droplet deposition on foliage. Model output includes values of droplet deposit density and size on foliage and ground as well as droplet concentration and size in the drift cloud. In addition, a detailed description of droplet atomizer characterization methods is presented along with a large number of atomizer spectrum results for atomizers in current use. An analysis of a number of forestry spraying innovations is presented. This text is an essential tool in assessing the efficacy and environmental impact of proposed and actual forest spray operations.

Forecasting the Response to Climate Change of the Major Natural Biotic Disturbance Regime in Ontario's Forests
Author: Jean-Noël Candau
Publisher:
ISBN:
Category : Science
Languages : en
Pages : 24
Book Description
Predicting the effect of climate change on insect populations can be used to estimate the costs and benefits of protecting forests from potential damage. In this report, the authors present an analysis of potential changes in the distribution of spruce budworm (Choristoneura fumiferana Clem.) defoliation under climate change in Ontario. They use an empirical model that relates defoliation to historical bioclimatic variables, and then apply climate change data to this model to predict potential changes in the distribution of defoliation.--Includes text from document.

Foundations of Ecological Resilience
Author: Lance H. Gunderson
Publisher: Island Press
ISBN: 1610911334
Category : Science
Languages : en
Pages : 497
Book Description
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.

Plant Disturbance Ecology
Author: Edward A. Johnson
Publisher: Academic Press
ISBN: 0128188146
Category : Nature
Languages : en
Pages : 564
Book Description
Disturbance ecology continues to be an active area of research, having undergone advances in many areas in recent years. One emerging direction is the increased coupling of physical and ecological processes, in which disturbances are increasingly traced back to mechanisms that cause the disturbances themselves, such as earth surface processes, mesoscale, and larger meteorological processes, and the ecological effects of interest are increasingly physiological. Plant Disturbance Ecology, 2nd Edition encourages movement away from the informal, conceptual approach traditionally used in defining natural disturbances and clearly presents how scientists can use a multitude of approaches in plant disturbance ecology. This edition includes nine revised chapters from the first edition, as well new, more comprehensive chapters on fire disturbance and beaver disturbance. Edited by leading experts in the field, Plant Disturbance Ecology, 2nd Edition is an essential resource for scientists interested in understanding plant disturbance and ecological processes. - Advances understanding of natural disturbances by combining geophysical and ecological processes - Provides a framework for collaboration between geophysical scientists and ecologists studying natural disturbances - Includes fully updated research with 5 new chapters and revision of 11 chapters from the first edition

Simulation Modeling of Forest Landscape Disturbances
Author: Ajith H. Perera
Publisher: Springer
ISBN: 3319198092
Category : Science
Languages : en
Pages : 324
Book Description
Forest landscape disturbances are a global phenomenon. Simulation models are an important tool in understanding these broad scale processes and exploring their effects on forest ecosystems. This book contains a collection of insights from a group of ecologists who address a variety of processes: physical disturbances such as drought, wind, and fire; biological disturbances such as defoliating insects and bark beetles; anthropogenic influences; interactions among disturbances; effects of climate change on disturbances; and the recovery of forest landscapes from disturbances—all from a simulation modeling perspective. These discussions and examples offer a broad synopsis of the state of this rapidly evolving subject.
