Book Description
The FACTS II (ASPEN FACE) infrastructure including 12 FACE [Free-Air Carbon dioxide Enrichment] rings, a central control facility, a central CO2 and O2 receiving and storage area, a central O3 generation system, and a dispensing system for CO2 and O3 was completed in 1997. The FACE rings were planted with over 10,000 plants (aspen, birch and maple). The entire system was thoroughly tested for both CO2 and O3 and was shown to be effective in delivering elevated CO2 and/or O3 on demand and at predetermined set points. The NCASI support to date has been extremely helpful in matching support for federal grants.

Book Description
These proceedings consist of papers presented at the 18th IUFRO workshop on Forest Growth Responses to the Pollution Climate of the 21st Century, held in Edinburgh in September 1998. Included are authoritative reviews and experimental evidence of forest growth responses in Europe and North America to the dominant components of air pollution, namely nitrogen and ozone, and their interactions with environmental influences. Nitrogen effects include changes in tree growth, nutrient status and biochemistry. Responses of root mycorrhiza and pathogenic fungi, and changes in trace gas fluxes and soil chemistry are also covered. Effects of the gaseous pollutants, O3, SO2 and O3/CO2 interactions, are discussed in terms of visible injury and biochemical changes. The role and methods of forest health monitoring programmes and the use of bioindicators are evaluated. This book is primarily for people who want a better understanding of how and why forests respond to air pollution, and the implications for the stability of forest ecosystems.

Book Description
This volume contains papers highlighting the diverse interests of modern ecologists. Areas covered range from modeling terrestrial carbon exchange and storage to the relationship between animal abundance and body size. Other papers address the free-air carbon dioxide enrichment in global change research; generalist predators, interaction strength, and food web stability; delays, demography, and cycles; and spatial root segregation. This volume is essential for all ecologists.

Book Description
Ecological and environmental research has increased in scope and complexity in the last few decades, from simple systems with a few managed variables to complex ecosystems with many uncontrolled variables. These issues encompass problems that are inadequately addressed using the types of carefully controlled experiments that dominate past ecological research. Contemporary challenges facing ecologists include whole ecosystem responses to planned restoration activities and ecosystem modifications, as well as unplanned catastrophic events such as biological invasions, natural disasters, and global climate changes. Major perturbations implicated in large-scale ecological alterations share important characteristics that challenge traditional experimental design and statistical analyses. These include: * Lack of randomization, replication and independence * Multiple scales of spatial and temporal variability * Complex interactions and system feedbacks. In real world ecology, standard replicated designs are often neither practical nor feasible for large-scale experiments, yet ecologists continue to cling to these same standard designs and related statistical analyses. Case studies that fully elucidate the currently available techniques for conducting large-scale unreplicated analyses are lacking. Real World Ecology: Large-Scale and Long-Term Case Studies and Methods is the first to focus on case studies to demonstrate how ecologists can investigate complex contemporary problems using new and powerful experimental approaches. This collection of case studies showcases innovative experimental designs, analytical options, and interpretation possibilities currently available to theoretical and applied ecologists, practitioners, and biostatisticians. By illustrating how scientists have answered pressing questions about ecosystem restoration, impact and recovery, global warming, conservation, modeling, and biological invasions, this book will broaden the acceptance and application of modern approaches by scientists and encourage further methodological development.

Book Description
Carbon moves through the atmosphere, through the oceans, onto land, and into ecosystems. This cycling has a large effect on climate – changing geographic patterns of rainfall and the frequency of extreme weather – and is altered as the use of fossil fuels adds carbon to the cycle. The dynamics of this global carbon cycling are largely predicted over broad spatial scales and long periods of time by Earth system models. This book addresses the crucial question of how to assess, evaluate, and estimate the potential impact of the additional carbon to the land carbon cycle. The contributors describe a set of new approaches to land carbon cycle modeling for better exploring ecological questions regarding changes in carbon cycling; employing data assimilation techniques for model improvement; and doing real- or near-time ecological forecasting for decision support. This book strives to balance theoretical considerations, technical details, and applications of ecosystem modeling for research, assessment, and crucial decision making. Key Features Helps readers understand, implement, and criticize land carbon cycle models Offers a new theoretical framework to understand transient dynamics of land carbon cycle Describes a suite of modeling skills – matrix approach to represent land carbon, nitrogen, and phosphorus cycles; data assimilation and machine learning to improve parameterization; and workflow systems to facilitate ecological forecasting Introduces a new set of techniques, such as semi-analytic spin-up (SASU), unified diagnostic system with a 1-3-5 scheme, traceability analysis, and benchmark analysis, for model evaluation and improvement Related Titles Isabel Ferrera, ed.

Book Description
This report explores the potential for mitigating the impacts of climate change by improved management and protection of marine ecosystems and especially the vegetated coastal habitat, or blue carbon sinks. The objective of this report is to highlight the critical role of the oceans and ocean ecosystems in maintaining our climate and in assisting policy makers to mainstream an oceans agenda into national and international climate change initiatives. While emissions' reductions are currently at the centre of the climate change discussions, the critical role of the oceans and ocean ecosystems has been vastly overlooked.
