Available in PDF, EPUB and Kindle. Book excerpt: This report uses data from a network of forest inventory plots sampled at two points in time, annual aerial insect and disease surveys, and specialized pest damage surveys to quantify the incidence and impact of insects, diseases, and other damaging agents on Oregon's forests. The number and volume of trees damaged or killed by various agents is summarized. Differences in the frequency and severity of damaging agents between various ownership categories and geographic regions of the state are investigated.

Book excerpt: The Fungal Community: Its Organization and Role in the Ecosystem, Third Edition addresses many of the questions related to the observations, characterizations, and functional attributes of fungal assemblages and their interaction with the environment and other organisms. This edition promotes awareness of the functional methods of classification over taxonomic methods, and approaches the concept of fungal communities from an ecological perspective, rather than from a fungicentric view. It has expanded to examine issues of global and local biodiversity, the problems associated with exotic species, and the debate concerning diversity and function. The third edition also focuses on current ecological discussions - diversity and function, scaling issues, disturbance, and invasive species - from a fungal perspective. In order to address these concepts, the book examines the appropriate techniques to identify fungi, calculate their abundance, determine their associations among themselves and other organisms, and measure their individual and community function. This book explains attempts to scale these measures from the microscopic cell level through local, landscape, and ecosystem levels. The totality of the ideas, methods, and results presented by the contributing authors points to the future direction of mycology.

This book was released on 2010 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: In July 2006, more than 170 researchers and managers from the United States, Canada, and Mexico convened in Boulder, Colorado, to discuss the state of the science in environmental threat assessment. This two-volume general technical report compiles peer-reviewed papers that were among those presented during the 3-day conference. Papers are organized by four broad topical sections--Land, Air and Water, Fire, and Pests/Biota--and are divided into syntheses and case studies. Land topics include discussions of forest land conversion and soil quality as well as investigations of species' responses to climate change. Air and water topics include discussions of forest vulnerability to severe weather and storm damage modeling. Fire topics include discussions of wildland arson and wildfire risk management as well as how people precieve wildfire risk and uncertainty. Pests/biota topics include discussions of risk mapping and probabilistic risk assessments as well as investigations of individual threats, including the southern pine beetle and Phytophora alni. Ultimately, this publication will foster exchange and collaboration between those who develop knowledge and tools for threat assessment and those who are responsible for managing forests and rangelands.
