Available in PDF, EPUB and Kindle. Book excerpt: This book highlights recent advances in the discipline of biogeochemistry that have directly resulted from the development of critical zone (CZ) science. The earth's critical zone (CZ) is defined from the weathering front and lowest extent of freely circulating groundwater up through the regolith and to the top of the vegetative canopy. The structure and function of the CZ is shaped through tectonic, lithologic, hydrologic, climatic, and biological processes and is the result of processes occurring at multiple time scales from eons to seconds. The CZ is an open system in which energy and matter are both transported and transformed. Critical zone science provides a novel and unifying framework to consider those coupled interactions that control biogeochemical cycles and fluxes of energy and matter that are critical to sustaining a habitable planet. Biogeochemical processes are at the heart of energy and matter fluxes through ecosystems and watersheds. They control the quantity and quality of carbon and nutrients available for living organisms, control the retention and export of nutrients affecting water quality and soil fertility, and influence the ability for ecosystems to sequester carbon. As the term implies, biogeochemical cycles, and the rates at which they occur, result from the interaction of biological, chemical, and physical processes. However, finding a unifying framework by which to study these interactions is challenging, and the different components of bio-geo-chemistry are often studied in isolation. The authors provide both reviews and original research contributions with the requirement that the chapters incorporate a CZ framework to test biogeochemical theory and/or develop new and robust predictive models regarding elemental cycles. The book demonstrates how the CZ framework provides novel insights into biogeochemistry.

Download or read book Climatic Controls on Critical Zone Nutrient Biogeochemistry in Semiarid and Mediterranean Ecosystems written by Morgan Elizabeth Barnes and published by . This book was released on 2020 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global climate models demonstrate that temperate ecosystems are likely to serve as carbon (C) sinks in the coming decades, however any realized increase in C storage on land will also require increases in the availabilities of plant essential nutrients such as nitrogen (N) and phosphorus (P). Additionally, nutrient limitation to plant productivity remains one of the most uncertain factors to global climate projections. Our understanding of how nutrient biogeochemistry is altered under different climatic conditions is unclear. Using a combination of field, laboratory, and advanced analytical techniques, I show P biogeochemistry is intrinsically related to soil development in a semiarid (White Mountains Elevational Transect) to Mediterranean (Southern Sierra Nevada Critical Zone Observatory) climatic gradient. Specifically, P stock increases, inorganic P transitions from calcium to iron and aluminum association, and organic P proportionally decreases with increasing climate-driven weathering. With increasing precipitation, soil and aboveground foliage became progressively more P-limited, whereas the microbial biomass and fine roots are more N-limited and enzyme activity is largely unaffected. Overall, the transition from a semiarid to Mediterranean climate creates more chemically weathered soil that is able to retain P that may not be readily bioavailable. These relatively more weathered soils appear to be relying on faster cycling organic P species to support ecosystem development. Furthermore, using three-dimensional resin capsule pots in a Mediterranean forest site, I characterized how nutrient fluxes under more biological l (PO43−, NH4, NO3−) or geochemical (Ca2+, Mg2+, and Na+) control are impacted by water year, seasonality, and depth to form hot spots (HS) or hot moments (HM). A multi-year drought occurred during the study, causing geochemically controlled nutrient fluxes to be transient over time and characterizing them as HM. Alternatively, biologically controlled outliers formed HS and HM. Macronutrient HS and HM are found at higher concentrations relative to the surrounding soil matrix, and co-occur in discrete spatial locations where belowground biomass can detect, proliferate, and exploit these resources. Overall, water flux controls nutrient biogeochemical cycles in these drylands. Therefore, nutrient HS and HM will likely play a disproportionate role in supporting ecosystem development in these temperature drylands under a changing climate.

Download or read book Ecosystem Biogeochemistry written by Christopher S. Cronan and published by Springer. This book was released on 2017-10-05 with total page 205 pages. 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.

Download or read book Biogeochemistry of Wetlands written by K. Ramesh Reddy and published by CRC Press. This book was released on 2022-09-10 with total page 926 pages. Available in PDF, EPUB and Kindle. Book excerpt: The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.

Available in PDF, EPUB and Kindle. Book excerpt: Oceans account for 50% of the anthropogenic CO2 released into the atmosphere. During the past 15 years an international programme, the Joint Global Ocean Flux Study (JGOFS), has been studying the ocean carbon cycle to quantify and model the biological and physical processes whereby CO2 is pumped from the ocean's surface to the depths of the ocean, where it can remain for hundreds of years. This project is one of the largest multi-disciplinary studies of the oceans ever carried out and this book synthesises the results. It covers all aspects of the topic ranging from air-sea exchange with CO2, the role of physical mixing, the uptake of CO2 by marine algae, the fluxes of carbon and nitrogen through the marine food chain to the subsequent export of carbon to the depths of the ocean. Special emphasis is laid on predicting future climatic change.
