Perspectives on Developing a Canadian Classification of Ecological Communities


Book Description

This report argues that Canada needs a national ecological community classification that would include all types of biotic communities. The report first provides background on classification science, ecological terminology, and the groups & principles of different ecosystem classifications. It then reviews various approaches to classification of vegetation communities and the ecological classification systems that have been already developed in Canada. The final section discusses the development of a standard national ecological community classification for Canada, proposes a structure of the Canadian Classification of Ecological Communities, and evaluates options for development of a Canadian National Vegetation Classification based on the International Classification of Ecological Communities system.




Terrestrial Vegetation of California, 3rd Edition


Book Description

This thoroughly revised, entirely rewritten edition of what is the essential reference on California’s diverse and ever-changing vegetation now brings readers the most authoritative, state-of-the-art view of California’s plant ecosystems available. Integrating decades of research, leading community ecologists and field botanists describe and classify California’s vegetation types, identify environmental factors that determine the distribution of vegetation types, analyze the role of disturbance regimes in vegetation dynamics, chronicle change due to human activities, identify conservation issues, describe restoration strategies, and prioritize directions for new research. Several new chapters address statewide issues such as the historic appearance and impact of introduced and invasive plants, the soils of California, and more.




Vegetation Description and Data Analysis


Book Description

Vegetation Description and Data Analysis: A PracticalApproach, Second Edition is a fully revised and up-datededition of this key text. The book takes account of recent advancesin the field whilst retaining the original reader-friendly approachto the coverage of vegetation description and multivariate analysisin the context of vegetation data and plant ecology. Since the publication of the hugely popular first edition therehave been significant developments in computer hardware andsoftware, new key journals have been established in the field andscope and application of vegetation description and analysis hasbecome a truly global field. This new edition includes fullcoverage of new developments and technologies. This contemporary and comprehensive edition of this well-known andrespected textbook will prove invaluable to undergraduate andgraduate students in biological sciences, environmental science,geography, botany, agriculture, forestry and biologicalconservation. * Fully international approach * Includes illustrative case studies throughout * Now with new material on: the nature of plant communities;transitional areas between plant communities; induction anddeduction of plant ecology; diversity indices and dominancediversity curves; multivariate analysis in ecology. * Accessible, reader-friendly style * Now with new and improved illustrations




Biodeterioration of Wooden Cultural Heritage


Book Description

Since prehistoric times and throughout the course of human evolution, wood has been an integral part of all civilizations. Wooden Cultural Heritage can be found worldwide, providing valuable information on the social and economic context of human history. Nonetheless, as a natural cellulosic material, wood shows low resistance to biodeterioration and thus wooden Cultural Heritage often fails to escape decomposition in both aquatic and terrestrial ecosystems. This book provides a comprehensive overview on the biodeterioration of wooden Cultural Heritage and describes the decay mechanisms of key organisms and microorganisms encountered in aquatic and terrestrial ecosystems. Cultural Heritage professionals, researchers and academics may explore within this book the associations between deteriogens, habitats and decay, which will assist them to understand wood biodeterioration and design effective prevention, mitigation and remediation strategies. The book presents case studies around the world to demonstrate the impact of biogenic deterioration on wooden Cultural Heritage and illustrates mechanisms and patterns in order to be a useful handbook of decay diagnosis. Lastly, by adopting a holistic approach to wood decay, basic concepts of wood technology, ecology, and deteriogens' biology are introduced, permitting readers of different scientific backgrounds to easily comprehend wood biodeterioration.

The Canadian Vegetation Classification System


Book Description

"A system is presented for classifying terrestrial vegetation in Canada. The system has seven levels defined by plant community physiognomy and species-dominance criteria; the composition of the upper four levels have been completed, whereas the remaining levels still require development"--Pref.




Ecological Regions of North America


Book Description

This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.







Computerized Plant Community Classification


Book Description

Ecological site classification can be subjective, and attempts have been made throughout Canada to develop computer models for the consistent classification of plots. This report describes the application of fuzzy logic technology to ecological land classification data. In this research, investigators translated into a simple fuzzy logic program a classification of the forested portion of the montane subregion of west central Alberta by plant community type (a more detailed level than ecosite). The program was tested, using the FuzzyTECH fuzzy logic software package, on 147 ecological site information system plots compiled by Alberta Environment. The results compare the computerized classification with that of experts, and reasons for discrepancies are identified.
