This volume summarizes the current knowledge on the exchange of trace gases between forests and the atmosphere with the restriction that exclusively carbon and nitrogen compounds are included. For this purpose the volume brings together and interconnects knowledge from different disciplines of biological and atmospheric sciences. It covers microbial and plant processes involved in the production and consumption of these trace gases; the exchange processes between forest soils and vegetation on the one hand, and the atmosphere on the other hand; the fate of the trace gases exchanged inside the atmosphere as well as environmental influences on the exchange of trace gases between forest ecosystems and the atmosphere. With this interdisciplinary approach the volume provides the background for an evaluation of the exchange of trace gases between forest ecosystems and the atmosphere and man-made disturbances of this exchange.

This excellent book covers techniques used for extrapolating measurements of trace gas fluxes and factors regulating the production, consumption and exchange of trace gases in terrestrial and aquatic environments.It provides a comprehensive summary of all aspects of scaling, from flux measurement techniques, geographic data, modelling, use of tracers and isotopes, inverse modelling and satellite-borne atmospheric observations. An interesting feature of the book is the fact that both fluxes from terrestrial and aquatic (marine) sources are discussed, along with the uncertainties in estimates of trace gas fluxes at different scales, including point, field, landscape, regional and global scale.As well as reviewing the state of the art in the field of scaling of fluxes of greenhouse gases, ozone and aerosol and their precursors, and acidifying compounds, the emphasis of this volume is on identification of gaps in knowledge, finding solutions, and determination of future research directions.

Many trace gases are exchanged between the atmosphere and the biosphere. Although much research has been published on the photosynthetic exchanges of carbon dioxide, oxygen, and water vapor, this book focuses on the importance of biogenic trace gases on atmosphere chemistry and ecosystem stability. Included are methane and its effect on the radiative properties of the atmosphere, hydrocarbons (isoprene and monoterpenes), and their role in the production of ozone and carbon monoxide. Also covered are sulfur and nitrogen gases, both of which can lead to ecosystem acidification. The biochemistry and physiology of production of these and other gases are investigated. Plant physiologists, ecologists, and atmospheric chemists and modelers will benefit from this book.

Atmospheric abudance of trace gases since the pre-industrial time has forced the earth's climate to change, threatening food security. Exchange of biogenic trace gases between the atmosphere and the biosphere is directly or indirectly influenced by the plants. This volume contains the latest findings on the correlation between the climate change and biogenic gas emission, plant response to elevated levels of carbon dioxide, temperature, ozone and UV-B in combination and alone, regulatory mechanism of methane, nitrous oxide and ammonia emission and their mitigating options. Ecologists, atmospheric scientists, plant physiologists, research scholars, teachers and post-graduate students will benefit from this book.

The material presented here is based on presentations and discussions held at the 1990 Sigtuna workshop. We have organized the material into five sections, the first containing papers of general relevance to all the developed research plans, followed by three sections divided by geographical regions (high-latitude, mid-latitude, and tropical ecosystem regions), and the final section dealing with rice paddy agriculture, which because of its potential role as a significant source of CH4 and N2O was singled out for a specific set of studies. Each section, except the first dealing with general issues, concludes with a working group report developed at the workshop. These reports identify specific research needs to address biosphere atmosphere exchange research for each region.

Climate change is expected to affect the exchange of gases between forest ecosystems and the atmosphere. In this review, we focus on a few related topics, including the emission of greenhouse gases from the forest floor, and vegetation fires and their impact on air quality and soil CO2 efflux. In particular, we summarise the current state of knowledge on O3 deposition in forest ecosystems, both for stomatal uptake and non-stomatal sinks. Based on such summaries, we discuss interactions between forests, atmospheric composition and climate, and finally outline directions for multi- and interdisciplinary research required for mechanistically understanding such interrelationships.

This book focuses on fluxes of energy, carbon dioxide and matter in and above a Central European spruce forest. The transition from a forest affected by acid rain into a heterogeneous forest occurred as a result of wind throw, bark beetles and climate change. Scientific results obtained over the last 20 years at the FLUXNET site DE-Bay (Waldstein-Weidenbrunnen) are shown together with methods developed at the site, including the application of footprint models for data-quality analysis, the coupling between the trunk space and the atmosphere, the importance of the Damköhler number for trace gas studies, and the turbulent conditions at a forest edge. In addition to the many experimental studies, the book also applies model studies such as higher-order closure models, Large-Eddy Simulations, and runoff models for the catchment and compares them with the experimental data. Moreover, by highlighting processes in the atmosphere it offers insights into the functioning of the ecosystem as a whole. It is of interest to ecologists, micrometeorologists and ecosystem modelers.
