Through a delicate balance between photosynthesis and respiration, terres trial ecosystems, and in particular forests, are today thought to take up a sig nificant part of the carbon dioxide emissions in the atmosphere, sometimes called the "terrestrial carbon sink".

Following the discovery of large petroleum reserves in northern Alaska, the US Department of Energy implemented an integrated field and modeling study to help define potential impacts of energy-related disturbances on tundra ecosystems.

Mangrove ecosystems are being increasingly threatened by human activities. This volume highlights the results of a ten-year German / Brazilian research project, called MADAM, in one of the largest continuous mangrove areas of the world, located in northern Brazil.

In this volume the dynamic patterns of human density and distribution are examined in relation to the viability of native species and the integrity of their habitats.

While most desiccation-tolerant plants belong to basal phylogenetic taxa, this capacity has also evolved among some vascular plant species.In this volume renowned experts treat plant desiccation tolerance at the organismic as well as at the cellular level.

Having been the fourth largest lake on the globe roughly 50 years ago, today the Aral Sea no longer exists. The first section provides an overview of the physical characteristics of the area and covers geological, pedological, geomorphological and climatological aspects and their dynamics, especially dust-storm dynamics.

Or does apparent simplicity mask a complex and ultimately baffling obstacle to the understanding of seasonality in even those few indicator plants and animals we know best, not to men tion the less known species or races making up the rest of each major land scape unit or ecosystem?

Permafrost Ecosystems offers valuable ecological data from a region that has long been inaccessible to scientists. This authoritative text explores permafrost forest diversity, structure, dynamics and physiology, in addition to its response to climate change.

This book assesses the current greenhouse gas (GHG) monitoring capabilities of Europe, identifies and quantifies the uncertainties involved, and outlines the direction to a continental scale GHG monitoring network.

The public's attitude toward air pollution in the United States evolved substantially during the 1960s. This concern was heightened by press reports of high elevation spruce-fir forest declines in the Adirondack and Appalachian Mountains and the decline and death of sugar maples in the northeastern United States and Canada.

At present, roughly half of the world's population lives in urban centers. A consequence of this growing trend is that millions of people are being exposed to harmful levels of urban air pollutants caused mainly by emissions from motor vehicles and from industrial and domestic activities involving the combustion of fossil fuels.

Five years of research carried out by the U.S. Department of Agriculture Forest Services' Northern Global Change Program, contributing to our understanding of the effects of multiples stresses on forest ecosystems over multiple spatial and temporal scales.

Proceedings of the VIth International Symposium on Amyloidosis, held in Oslo, Norway, 5-8 August 1990.

Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species interactions, phenotypic plasticity, and the importance of biodiversity.

A well-structured and comprehensive summary of the strategies and several case studies for applying molecular plant genomics in the fields of plant ecotoxicology and plant ecology.

This book provides an up-to-date coverage of green (vegetated) roof research, design, and management from an ecosystem perspective.

Sources and sinks of CO associated with land use can be 2 significant determinants of the rate and magnitude of atmospheric CO change. Thus, land-use change and associated biological 2 processes become important elements in assessments of future atmospheric CO 2 increase;

Case Studies of Exosystem Dynamics Under a Spectrum of Land Use-Intensities

This book addresses basic questions concerning the ecological relationships and current conditions of the major river systems in Florida .

Human colonization of New Zealand has dramatically altered the resident biota, introduced numerous alien organisms to these once remote islands, and exported local species to the world. The book tests current theories about the success of invaders and evaluates principles for effective management of biological invasions worldwide.

The last 25 years have seen significant advances in our understanding of the mycorrhizal fungi that colonize most of the world's plants, and the mycorrhizal networks that form and extend into the soil beyond plant roots.

This volume summarizes our currentunderstanding of biological soil crusts (biocrusts), which are omnipresent indryland regions. The authorsshow that biocrusts are an integral part of dryland ecosystems, stabilizingsoils, influencing plant germination and growth, and playing a key role incarbon, nitrogen and water cycling.

Large terrestrial mammalian herbivores play critical roles in ecosystems by acting as regulators of energy and nutrient cycles, modulators of plant community composition and grassland-woodland transitions, agents of seed dispersal, and as prey for large carnivores.

This book offers a panorama of recent scientific achievements produced through the framework of the Large-Scale Biosphere-Atmosphere programme (LBA) and other research programmes in the Brazilian Amazon.

This book provides an up-to-date coverage of green (vegetated) roof research, design, and management from an ecosystem perspective.

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.

This study brings together decades of research on the modern natural environment of Washington's Olympic Peninsula, reviews past research on paleoenvironmental change since the Late Pleistocene, and finally presents paleoecological records of changing forest composition and fire over the last 14,000 years.

The last 25 years have seen significant advances in our understanding of the mycorrhizal fungi that colonize most of the world's plants, and the mycorrhizal networks that form and extend into the soil beyond plant roots.
