A discussion of the direct and indirect mechanisms by which fire and climate interact to influence carbon cycling in North American boreal forests. The first section summarizes the information needed to understand and manage fires' effects on the ecology of boreal forests and its influence on global climate change issues. Following chapters discuss in detail the role of fire in the ecology of boreal forests, present data sets on fire and the distribution of carbon, and treat the use of satellite imagery in monitoring these regions as well as approaches to modeling the relevant processes.

Das Buch gibt eine grundlegende Einführung in die zonale Gliederung der Erde nach natur- und agarräumlichen Aspekten. Das hier vorgestellte Konzept zur erdräumlichen Gliederung und inhaltlichen Fassung der Zonen geht neue Wege und berücksichtigt moderne ökologische Untersuchungen. Die Darstellung der Böden erfolgt nach dem jüngsten Stand der Bodenklassifikation und bietet damit auch wichtige Informationen zur globalen Differenzierung nach Nutzungspotentialen. Der Festlandbereich wird in Ökozonen unterteilt. Dem regionalen Teil geht ein allgemeiner Teil voraus, in dem wichtige Begriffe und Methoden der Ökosystemforschung vorgestellt werden. Ein eigenes Kapitel widmet sich dem Klimawandel und dessen Einfluss auf die ökozonale Gliederung der Erde. Die Kapitel behandeln jeweils die Hauptabschnitte: - Verbreitung - Klima - Relief und Gewässer - Böden - Vegetation und Tierwelt - Landnutzung

This book will draw attention to the residuals in pan-borealforest fires and synthesize the state of knowledge. It willdo so by: (a) Examining the concept of fire residuals fromdifferent perspectives, (b) Reviewing the growing body ofscientific literature on the topic, (c) Conceptualizing theprocess of residual formation in relation to scale of firedisturbance, (d) Discussing the roles of fire residuals inecological processes, (e) Describing approaches and methods ofstudying fire residuals, (f) Compiling and summarizing what isknown about fire residual vegetation with respect to their extent,spatial patterns, and temporal changes, (g) Discussing howthe knowledge of fire residuals is applied in forest management,including social perspective, and (h) Synthesizing the state ofknowledge, identifying its uncertainties and gaps, and proposingresearch hypotheses. The authors use pan-borealscientific literature on boreal fire residuals as well as firebehaviour, fire ecology, habitat ecology, and geochemicalprocesses. For readers this book will be a reference forknowledge to date and a meta-analysis of research trends during thepast few decades. In addition, the authors judiciouslyinclude views constructed from their observations and researchexperience, from boreal Canada, when they synthesize andconceptualize the knowledge. They also incorporateinformation extracted from their discussions and interactions withNorth American and European ecologists, forest managers, andconservationists to provide insight to different views andperspectives on the fire residuals of the boreal forest system. This book will inform researchers and students who studyboreal forest ecology, as well as policymakers and forest managerswho apply forest ecological knowledge in forest management. This book provides a review and coalescence of the currentknowledge of boreal forest fire residuals, which at present issporadic and has not been unified or synthesized. Moreover,these are presently viewed myopically and parochially, rather thanholistically. The intent of the synthesis is to identifyknowledge uncertainties and gaps and propose topics for futureresearch. Most importantly, it brings together fire behaviour,ecological scale, vegetation ecology, and conservation biology toconceptualize forest fire residuals. Although focused onboreal forests, the contents and principles presented are also bepertinent to other large-scale fire driven forest systems, such asdry montane forests in North America and Australian eucalyptforests. This book will add to the current knowledge base byproviding a source of significant literature to-date, an in-depthexamination of baseline concepts of forest fire residuals, as wellas questions and research ideas to address the identified gaps. Thetiming is ideal because the knowledge base is beginning to expandand the interest in the topic is increasing: such a synthesis wouldprovide an important foundation for future advances in this veryrelevant topical area. The book is a compact, yet comprehensive,dissertation of remnant vegetation in boreal forest fires withrespect to their formation, role in ecological processes, appliedimportance, and a synthesis of state-of-the-knowledge and futureresearch directions. The scope is boreal forests worldwide,including North America, Europe, and Asia. Brief TOC: Why theinterest in boreal fire residuals; what are fire residuals; how arefire residuals formed; what are the ecological roles of the fireresiduals; what is the role of residuals in forest managementapplications; synthesis, knowledge, uncertainties and researchneeds.

Gegenstand des vorliegenden Buchs ist die Pflanzendecke der Erde, wobei neben einer knapp gehaltenen Beschreibung der Vegetationstypen vor allem die kausalen Zusammenhänge zwischen dem Wuchsort charakteristischer (repräsentativer) Pflanzenarten und Pflanzengemeinschaften einerseits und entwicklungsgeschichtlich-historischen, zeitlichen bzw. räumlichen, ökophysiologischen sowie anthropogenen Bedingungen andererseits vermittelt werden. Zwar liegt der Schwerpunkt auf der vom Menschen nicht oder wenig beeinflussten „naturbetonten“ Pflanzendecke; berücksichtigt wird aber auch die „kulturbetonte“ Vegetation, die in klimatisch bzw. edaphisch begünstigten Regionen heute den größeren Flächenanteil einnimmt. Nach einem einführenden Kapitel, das die Grundlagen für die vegetationsökologische Gliederung der Erdoberfläche enthält, werden die Lebensbedingungen der zonalen, extrazonalen und azonalen Vegetation des Flachlands und der Gebirge von den äquatornahen immerfeuchten Tropen bis zu den Polargebieten dargestellt und mit vielen Tabellen, farbigen Graphiken und zahlreichen Fotos illustriert. Kastentexte bieten darüber hinaus ergänzende Informationen zu Spezialthemen. Ein umfangreiches Literaturverzeichnis erleichtert den Zugang zu vertiefenden Publikationen.

Wildland fire is an integral part of ecosystem mgmt. and is essential in maintaining functional ecosystems, but air pollutants emitted from those fires can be harmful to human health and welfare. This review of what is known about the effects of fire on air quality will assist those in the fire and air quality mgmt. communities. Contents: (1) Intro.; Scope; Framework; Prior Work; Changes in Fire Policy; (2) Air Quality Regulations and Fire; (3) Overview of Air Pollution from Fire; (4) Characterization of Emissions from Fires; (5) Transport, Dispersion, and Modeling of Fire Emissions; (6) Atmospheric and Plume Chemistry; (7) Estimating the Air Quality Impacts of Fire; (8) Consequences of Fire on Air Quality; (9) Recommend. for Future Research.
