Book Description
Dothistroma septosporum Dorog. Morelet is an emergent fungal pathogen of pine responsible for increasingly severe and widespread damage in British Columbia. Native lodgepole pine (Pinus contorta var. latifolia) is considered highly susceptible, but has been extensively planted due to its commercial value. Current management options involve either avoidance or species diversification. Quantitative resistance to Dothistroma has been observed in several pine species, and further identification of resistant lodgepole pine varieties is important for future management of the disease. My objectives were to determine the historical climatic influences on constitutive foliar terpene levels, identify foliar secondary metabolites associated with resistance and historical disease pressure, and to ascertain the in vitro effects of these compounds. I quantified foliar secondary metabolites from both seed orchard and resistance trial lodgepole pines, many of which were identified as terpenes. I quantified the Dothistroma outbreak history of lodgepole pine provenances using dendrochronological methods, and the climate history of these provenances using an interpolated historical climate model. I found that constitutive foliar levels of specific terpenes significantly correlated (P

Book Description
Today, forest health and the management of threats towards it are attracting more and more attention on a global scale. This book covers the most recent advances in the management of forest diseases, including the epidemiology and infection biology of forest pathogens, and forest protection based on integrated pest and disease management approaches. A comprehensive range of diseases caused by viruses, bacteria, fungi and other organisms are discussed in detail, making this book essential reading for forest managers and extension specialists. Written by recognized authorities in the subject of forest health, this book also provides a wealth of information useful for researchers and lecturers of forest pathology and ecology.

Book Description
This volume addresses the similarities and also the differences in the genomes of soil saprophytes, symbionts, and plant pathogens by using examples of fungal species to illustrate particular principles. It analyzes how the specific interactions with the hosts and the influence of the environment may have shaped genome evolution. The relevance of fungal genetic research and biotechnological applications is shown for areas such as plant pathogenesis, biomass degradation, litter decomposition, nitrogen assimilation, antibiotic production, mycoparasitism, energy, ecology, and also for soil fungi turning to human pathogens. In addition to the model organisms Neurospora and Aspergillus, the following species are covered providing a view of pathogens and mutualists: Trichoderma, Fusarium oxysporum, Cochliobolus heterostrophus, Penicillium chrysogenum, Rhizopus oryzae, Podospora anserina, and species belonging to Agaricomycetes, Archaeorhizomycetes and Magnaporthaceae. Ecology and potential applications have guided the choice of fungal genes to be studied and it will be fascinating to follow the trends of future sequencing projects.

Book Description
This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.

Book Description
Dendroecologists apply the principles and methods of tree-ring science to address ecological questions and resolve problems related to global environmental change. In this fast-growing field, tree rings are used to investigate forest development and succession, disturbance regimes, ecotone and treeline dynamics and forest decline. This book of global scope highlights state-of-the-science dendroecological contributions to paradigm-shifts in our understanding of ecophysiology, stand dynamics, disturbance interactions, forest decline and ecosystem resilience to global environmental change and is fundamental to better managing our forested ecosystems for the full range of ecosystem goods and services that they provide.
