Principles and Standards for Measuring Primary Production
Author: Timothy J. FaheyPublisher: Oxford University Press
ISBN: 9780198037729
Category : Science
Languages : en
Pages : 288
Book Description
Principles and Standards for Measuring Net Primary Production in Long-Term Ecological Studies is the first book to establish a standardized method for measuring net primary productivity (NPP) in ecological research. Primary productivity is the rate at which energy is stored in the organic matter of plants per unit area of the earth's surface. As the beginning stage of the carbon cycle, our ability to accurately measure NPP is essential to any ecological analysis, as well as agronomy, forestry, fisheries, limnology and oceanography. In fact, NPP measurements are fundamental to ecosystem studies at thousands of sites around the world. All 26 LTER sites will be expected to collect and report data using these new standards, but the standards should reach well beyond LTER sites. Identified standards for NPP measurements will allow researchers from diverse biomes to authoritatively compare measurements among their sites. Comparable measurements will build a foundation for a broad scale understanding of the environmental, biological, and nutrition controls on NPP. The book includes chapters for each of the critical biome types, including special techniques that work best in each environment. For example, there are chapters that discuss grassland ecosystems, urban ecosystems, marine pelagic ecosystems, forest ecosystems, and salt marsh ecosystems, among others.
Methods in Biogeochemistry of Wetlands
Author: Ronald D. DeLaunePublisher: John Wiley & Sons
ISBN: 0891189602
Category : Technology & Engineering
Languages : en
Pages : 1024
Book Description
Wetlands occur at the interface of upland and aquatic ecosystems, making them unique environments that are vital to ecosystem health. But wetlands are also challenging to assess and understand. Wetland researchers have developed specialized analytical methods and sampling techniques that are now assembled for the first time in one volume. More than 100 experts provide key methods for sampling, quantifying, and characterizing wetlands, including wetland soils, plant communities and processes, nutrients, greenhouse gas fluxes,redox-active elements, toxins, transport processes, wetland water budgets,and more.
Plankton Ecology of the Southwestern Atlantic
Author: Mónica S. HoffmeyerPublisher: Springer
ISBN: 3319778692
Category : Science
Languages : en
Pages : 586
Book Description
This book integrates a variety of issues such as regional settings of productivity and nutrient cycling; plankton of coastal and shelf systems; plankton, climate change and human-induced changes; harmful algae and their impacts; and gelatinous zooplankton. This book explores the intriguing marine plankton communities of the SWA region of South America encompassing low to high latitude environments, framed by a complex hydrographic background and global climate change. This vast and iconic region has been largely under-recognized and under-studied. However, in recent years a strong interest has emerged along with the acknowledgment of its high biological productivity. The book concludes by discussing conservation in the region, highlighting regional biodiversity hotspots where the challenges of climate change, habitat loss, and other threats to biodiversity may be particularly acute. Plankton Ecology of the Southwestern Atlantic is a timely synthesis of the field, setting a new baseline for future research. It will be important reading for both researchers and graduate students, and will also be of interest and use to a professional audience of oceanographers, conservation biologists, stake holders and educated science enthusiasts
Assuring Data Quality at U.S. Geological Survey Laboratories
Author: National Academies of Sciences, Engineering, and MedicinePublisher: National Academies Press
ISBN: 0309495628
Category : Science
Languages : en
Pages : 89
Book Description
The U.S. Geological Survey (USGS) mission is to provide reliable and impartial scientific information to understand Earth, minimize loss of life and property from natural disasters, and manage water, biological, energy, and mineral resources. Data collection, analysis, interpretation, and dissemination are central to everything the USGS does. Among other activities, the USGS operates some 250 laboratories across the country to analyze physical and biological samples, including water, sediment, rock, plants, invertebrates, fish, and wildlife. The data generated in the laboratories help answer pressing scientific and societal questions or support regulation, resource management, or commercial applications. At the request of the USGS, this study reviews a representative sample of USGS laboratories to examine quality management systems and other approaches for assuring the quality of laboratory results and recommends best practices and procedures for USGS laboratories.
Biogeochemistry

ISBN: 0123858755
Category : Science
Languages : en
Pages : 688
Book Description
Biogeochemistry—winner of a 2014 Textbook Excellence Award (Texty) from the Text and Academic Authors Association—considers how the basic chemical conditions of the Earth, from atmosphere to soil to seawater, have been and are being affected by the existence of life. Human activities in particular, from the rapid consumption of resources to the destruction of the rainforests and the expansion of smog-covered cities, are leading to rapid changes in the basic chemistry of the Earth. This expansive text pulls together the numerous fields of study encompassed by biogeochemistry to analyze the increasing demands of the growing human population on limited resources and the resulting changes in the planet's chemical makeup. The book helps students extrapolate small-scale examples to the global level, and also discusses the instrumentation being used by NASA and its role in studies of global change. With extensive cross-referencing of chapters, figures and tables, and an interdisciplinary coverage of the topic at hand, this updated edition provides an excellent framework for courses examining global change and environmental chemistry, and is also a useful self-study guide. Winner of a 2014 Texty Award from the Text and Academic Authors Association Calculates and compares the effects of industrial emissions, land clearing, agriculture, and rising population on Earth's chemistry Synthesizes the global cycles of carbon, nitrogen, phosphorous, and sulfur, and suggests the best current budgets for atmospheric gases such as ammonia, nitrous oxide, dimethyl sulfide, and carbonyl sulfide Includes an extensive review and up-to-date synthesis of the current literature on the Earth's biogeochemistry
