Due to demands placed on natural resources globally and subsequent deterioration of the environment, there is a need to source and develop appropriate technology to satisfy this requirement. For decades mankind has largely depended on natural resources such as fossil fuels to meet the ever increasing energy demands. Realizing the finite nature of these resources, emphasis is now shifting to investigating alternate energy source governed by environmentally friendly principles. The abundance of biomass and associated favorable techno-economics has recently changed global perceptions of harnessing biomass as a valuable resource rather than a waste. To this end this book aims to make a contribution to exploring further this area of biomass research and development in the form of a compilation of chapters and covering areas of ecological status of different types of biomass and the roles they play in ecosystems, current status of biomass utilization and deriving energy and other value added products from biomass. In this context biomass can be defined as large plants and trees and different groups of microorganisms. This book will serve as an invaluable resource for scientists and environmental managers in planning solutions for sustainable development.

Forest ecosystems are important because of the key role in reducing atmospheric greenhouse gas concentrations by storing a large amount of carbon in biomass and soils. The relative amount of above-ground biomass allocated among different tree tissues is a functional indicator of forests’ health reflecting the material flow, the wood quality and the plant survival strategy. The way in which plants steer their photosynthetic product across their compartments is not fixed but likely vary over time, across growth economies and among species and, lastly, is influenced by plant size and climate, Obtaining a qualitative/quantitative understanding of the influence that these factors have in both growth and biomass allocation is of fundamental importance either in understanding plant ecology and evolution and into developing environmental policies and useful forest management practices to cope with future climate change.

Wood as Raw Material: Source, Structure, Chemical Composition, Growth, Degradation and Identification focuses on the scientific advancements in general forestry. This book discusses the value of wood as a raw material as looked upon from biological, botanical, and technical perspective. Organized into 12 chapters, this book starts with an overview of the importance of forest trees as sources of wood. This text then examines the chemical composition and ultrastructure of wood. Other chapters explain the biological mechanisms of wood and bark formation by forest trees. This book discusses as well the certain fundamental relationships between tree growth and wood structure. The final chapter deals with wood identification in North America and European forest tree species. This book is a valuable resource for students engaged in the study of forest management, wood science and technology, tree physiology, silviculture, forest soils, forest genetics, forest engineering, pulp and paper technology, forest and wood pathology, and other specialized areas. Foresters and technologists will also find this book useful.

Early biogeographers such as Alexander von Humboldt recognized the broad-scale coupling of vegetation and climate. This observation shaped the modern biome concept which organizes ecosystems by assumed relationships to environmental controls. This approach has been criticized for missing key impacts on the distribution and functioning of biomes like historical contingency, biogeographic history, disturbance ecology, and evolution. Are biomes still a convenient framework for organizing our understanding of biodiversity? What factors determine the functional differences among and within biomes, and at what spatial, temporal, and phylogenetic scales are those drivers most important? How can we better represent the functional characteristics and dynamics of ecosystems? This Research Topic highlights the latest discussions and research on biomes, drawing from a wide range of approaches spanning from macroecology and phylogeography to remote sensing and modelling ecosystem responses to global change.
