Book excerpt: Rocky Mountain National Park was established in 1915, one year before the creation of the National Park Service. The mandate of the National Park Service is to preserve and protect areas of exquisite beauty and cultural value for the benefit and enjoyment of future generations. National parks mean many things to many people, and, in often stirring words, a National Parks and Conservation Association report states the National Park System is a magnificent and uniquely American gift to the American people and the world. In the early years of the Service, park superintendents actively promoted and developed parks to accommodate visitors. Then, as now, parks represented a democratic ideal, that even the greatest treasures should be available to all. Seventy five years ago, however, park managers saw little need for active management of natural resources, unless it was to enhance visitors' experience. And few managers saw the need for a stable and independent research program on which to base management decisions. Thus began a legacy of erratic, often passive, resource management based more on politics and in-house studies than on validated scientific informa tion. The world is a different place than it was 75 years ago. Human population growth, changes in land use, and ever more sophisticated technology affect the very fabric of life on Earth. As local-, regional-, and global-scale changes occur from human tampering with the environment, the integrity of natural ecosystems is threatened worldwide.

Book excerpt: We examined the influence of snow regime on subalpine ecosystem C and N cycling at Mount Rainier under ambient conditions and in climate change scenarios. Timing of snow release influenced ecosystem C and N storage and loss. Climate change may reduce snow accumulation by up to 80% at Mount Rainier by 2050. Snowpack loss may enhance ecosystem C and N accumulation during the growing season and increase winter N leaching.

Book excerpt: For the past 4 billion years, the chemistry of the Earth's surface, where all life exists, has changed remarkably. Historically, these changes have occurred slowly enough to allow life to adapt and evolve. In more recent times, the chemistry of the Earth is being altered at a staggering rate, fueled by industrialization and an ever-growing human population. Human activities, from the rapid consumption of resources to the destruction of the rainforests and the expansion of smog-covered cities, are all leading to rapid changes in the basic chemistry of the Earth. The Third Edition of Biogeochemistry considers the effects of life on the Earth's chemistry on a global level. This expansive text employs current technology to help 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 the Earth's changing chemistry as the focus, this text pulls together the many disparate fields that are encompassed by the broad reach of biogeochemistry. With extensive cross-referencing of chapters, figures, and tables, and an interdisciplinary coverage of the topic at hand, this text will provide an excellent framework for courses examining global change and environmental chemistry, and will also be a useful self-study guide. Emphasizes the effects of life on the basic chemistry of the atmosphere, the soils, and seawaters of the EarthCalculates and compares the effects of industrial emissions, land clearing, agriculture, and rising population on Earth's chemistrySynthesizes 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 sulfideIncludes an extensive review and up-to-date synthesis of the current literature on the Earth's biogeochemistry.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook presents a comprehensive process-oriented approach to biogeochemistry that is intended to appeal to readers who want to go beyond a general exposure to topics in biogeochemistry, and instead are seeking a holistic understanding of the interplay of biotic and environmental drivers in the cycling of elements in forested watersheds. The book is organized around a core set of ecosystem processes and attributes that collectively help to generate the whole-system structure and function of a terrestrial ecosystem. In the first nine chapters, a conceptual framework is developed based on distinct soil, microbial, plant, atmospheric, hydrologic, and geochemical processes that are integrated in the element cycling behavior of watershed ecosystems. With that conceptual foundation in place, students then proceed to the final three chapters where they are challenged to think critically about integrated element cycling patterns; roles for biogeochemical models; the likely impacts of disturbance, stress, and management on watershed biogeochemistry; and linkages among patterns and processes in watersheds experiencing novel environmental changes. Included with the text are figures, tables of comparative data, extensive literature citations, a glossary of terms, an index, and a set of 24 biogeochemical problems with answers. The problems are intended to support chapter concepts and to demonstrate how critical thinking skills, simple algebra, and thoughtful human logic can be used to solve applied problems in biogeochemistry that might be encountered by a research scientist or a resource manager. Using this book as an introduction to biogeochemistry, students will achieve a level of subject mastery and disciplinary perspective that will permit them to see and to interpret the individual components, interactions, and synergies that are represented in the dynamic element cycling patterns of watershed ecosystems.

Book excerpt: When we originally published Biogeochemistry of a Forested Ecosystem in 1977, the Hubbard Brook Ecosystem Study (HBES) had been in existence for 14 years, and we included data through 1974, or a biogeo chemical record of 11 years. Now our continuous, long-term biogeo chemical records cover more than 31 years, and there have been many changes. The most notable change, however, is that three of our coauthors on the original volume are now deceased. They are deeply missed in so many ways. In spite of the longer records, different trends, and new insights, we believe that the basic concepts and approaches we presented in 1977 represent the most valuable contribution of the original edition. They are still valid and useful, particularly for an introductory study of, or course in, biogeochemistry. Our goal in this revision is to preserve these fea tures, correct errors, and revise or eliminate misleading or ambiguous short-term data (11 years!), while maintaining approximately the original length and the modest cost.

This book was released on 2013-08-13 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this Third Edition is to update long-term data presented in earlier editions and to generate new syntheses and conclusions about the biogeochemistry of the Hubbard Brook Valley based on these longer-term data. There have been many changes, revelations, and exciting new insights generated from the longer data records. For example, the impact of acid rain peaked during the period of the HBES and is now declining. The longer-term data also posed challenges in that very marked changes in fluxes occurred in some components, such as hydrogen ion and sulfate deposition, calcium and nitrate export in stream water and biomass accumulation, during the almost 50 years of record. Thus, presenting “mean” or “average” conditions for many components for such a long period, when change was so prominent, do not make sense. In some cases, pentads or decades of time are compared to show these changes in a more smoothed and rational way for this long period. In some cases, a single period, often during periods of rapid change, such as acidification, is used to illustrate the main point(s). And, for some elements a unique mass balance approach, allowing the calculation of the Net Ecosystem Flux (NEF), is shown on an annual basis throughout the study.

This book was released on 2013 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildfires have the potential to dramatically alter forest carbon (C) storage and nitrogen (N) availability, but the long-term biogeochemical legacy of these events is poorly understood. I used a high-resolution lake-sediment record of fire occurrence and biogeochemical change from a subalpine watershed in Colorado, USA, to examine the nature, magnitude, and duration of fire-induced ecosystem impacts over the last ca. 4250 yr. Superposed Epoch Analysis (SEA) revealed pronounced biogeochemical responses to multiple high-severity fires, inferred from statistically significant peaks in charcoal accumulation and magnetic susceptibility (an indicator of erosion). On average, fires were followed closely by significant increases in bulk sediment N isotopic composition (d15N) and bulk density, and declines in %C and %N - likely reflecting destruction of the forest floor, terrestrial C and N losses, and erosion. Anomalously low sediment C:N ca. 20-50 yr after fires suggests a long-lived reduction in terrestrial organic matter subsidies to the lake. The magnitude of post-fire change was well-correlated with charcoal peak magnitude, indicating that the extent of disturbance impacts scaled directly with inferred fire size and/or severity. Trends ca. 30-75 yr following fire, including a significant decline in d15N, were consistent with patterns observed in chronosequences of forest C and N accumulation, suggesting that terrestrial successional processes were reflected in the sediments. The results of this study, the first to systematically test the utility of lake-sediment d15N as an indicator of fire-induced N cycle change, indicate that high-resolution analysis of sediment records may offer a unique and powerful tool for elucidating the effects of fire on ecosystem biogeochemistry over decades to millennia.

This book was released on 2013-06-29 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest ecosystems represent a major type ofland use in Germanyand in Europe. They provide a number of functions, or ecosystem services, beneficial to humans, namely biomass production, regulation of the water- and energy cyde, C and N sequestration, erosion control, recreation, and they act as habitat for numerous species. The stability of forest ecosystems in Europe as influenced by the deposition of air pollutants has been a matter of debate for more than 20 years. Besides atmospheric deposition, other environmental conditions affecting forest ecosystems, such as temperature, CO content of the atmosphere 2 and precipitation, have significantly changed in the past and continue to change in the future. Quantifying and predicting the effects of these changes on ecosys tem functioning are achallenge to ecosystem research and also a requirement to establish sustainable use of forest ecosystems in the future. This book summarizes results of long-term, interdisciplinary ecosystem research conducted in two forested catchments and coordinated at the Bayreuth Institute of Terrestrial Ecosystem Research (BITÖK), University of Bayreuth, Germany. It does not aim to summarize all the research of BITÖ K in the past decade, which would go far beyond the studies in these two catch ments. Instead, we concentrate here on the long-term developments in the biogeochemistry of carbon and mineral elements and on the water cyde, at both the plot and the catchment scale.
