Biogea (Univocal)
by Michel SerresBiogea is a mixture of poetry, philosophy, science, and biography exemplary of the style that has made Michel Serres one of the most extraordinary thinkers of his age. His philosophical and poetic inquiry sings in praise of earth and life, what he names singularly as Biogea. In these times when species are disappearing, when catastrophic events such as earthquakes and tsunamis impale the earth, Serres wonders if anyone &“worries about the death pangs of the rivers.&” And for Serres, one can ask the same question of philosophy as the humanities increasingly find themselves in need of defenders. Today, all living organisms discover themselves part of this Biogea. &“Today we have other neighbors, constituents of the Biogea: the sea, my lover; our mother, the Earth, becomes our daughter; this beautiful breeze which inspires the spirit, a spiritual mistress; our light friends, the fresh and flowing waters.&”
Biogenetic Paradoxes of the Nation: Finncattle, Apples, and Other Genetic-Resource Puzzles (Experimental Futures)
by Sakari TamminenIn 1992, the Convention on Biological Diversity (CBD), signed by over 160 countries and hailed as the key symbol of a common vision for saving Earth's biodiversity, set forth three primary mandates: preserving biodiversity, using biodiversity components sustainably, and enabling economic benefit-sharing. The CBD—which gave signatory countries the ability to claim sovereignty over nonhuman genetic resources native to each nation—defined biodiversity through a politics of nationhood in ways that commodified genetic resources. In Biogenetic Paradoxes of the Nation Sakari Tamminen traces the ways in which the CBD's seemingly compatible yet ultimately paradox-ridden aims became manifest in efforts to create, conserve, and capitalize on distinct animal and plant species. In using Finland as a case study with which to understand the worldwide efforts to convert species into manifestations of national identity, Tamminen shows how the CBD's policies contribute less to biodiversity conservation than to smoothing the way for frictionless operation of biotechnologically assisted circuits of the global bioeconomy. Tamminen demonstrates how an intimate look at the high-level politics and technical processes of defining national genetic resources powerfully illuminates the limits of anthropocentric biopolitical theory.
Biogenic Nano-Particles and their Use in Agro-ecosystems
by Ajit Varma Devendra K. Choudhary Mansour Ghorbanpour Prachi BhargavaSeveral nano-scale devices have emerged that are capable of analysing plant diseases, nutrient deficiencies and any other ailments that may affect food security in agro-ecosystems. It has been envisioned that smart delivery systems can be developed and utilised for better management of agricultural ecosystems. These systems could exhibit beneficial, multi-functional characteristics, which could be used to assess and also control habitat-imposed stresses to crops.Nanoparticle-mediated smart delivery systems can control the delivery of nutrients or bioactive and/or pesticide molecules in plants. It has been suggested that nano-particles in plants might help determine their nutrient status and could also be used as cures in agro-ecosystems. Further, to enhance soil and crop productivity, nanotechnology has been used to create and deliver nano fertilizers, which can be defined as nano-particles that directly help supply nutrients for plant growth and soil productivity. Nano-particles can be absorbed onto clay networks, leading to improved soil health and more efficient nutrient use by crops. Additionally, fertilizer particles can be coated with nano-particles that facilitate slow and steady release of nutrients, reducing loss of nutrients and enhancing their efficiency in agri-crops. Although the use of nanotechnology in agro-ecosystems is still in its early stages and needs to be developed further, nano-particle-mediated delivery systems are promising solutions for the successful management of agri-ecosystems. In this context, the book offers insights into nanotechnology in agro-ecosystems with reference to biogenic nanoparticles. It highlights the: • occurrence and diversity of Biogenic Nanoparticles• mechanistic approach involved in the synthesis of biogenic nanoparticles• synthesis of nanoparticles using photo-activation, and their fate in the soil ecosystem• potential applications of nanoparticles in agricultural systems• application and biogenic synthesis of gold nanoparticles and their characterization• impact of biogenic nanoparticles on biotic stress to plants• mechanistic approaches involved in the antimicrobial effects and cytotoxicity of biogenic nanoparticles• role of biogenic nanoparticles in plant diseases management• relevance of biological synthesized nanoparticles in the longevity of agricultural crops • design and synthesis of nano-biosensors for monitoring pollutants in water, soil and plant systems• applications of nanotechnology in agriculture with special refer to soil, water and plant sciencesA useful resource for postgraduate and research students in the field of plant and agricultural sciences, it is also of interest to researchers working in nano and biotechnology.

Biogenic Nanomaterials for Environmental Sustainability: Principles, Practices, and Opportunities (Environmental Science and Engineering)
by Maulin P. Shah Navneeta Bharadvaja Lakhan KumarEnvironmental pollution is a worldwide concern now. A major section of the world population is struggling for drinking water. Polluted soil is resulting into low agricultural productivity and thus creating challenges in the way of sustainable livelihood of a large section of human population. Biological treatment can offer both green solutions for wastewater treatment and resource recovery as well. Like algal-based systems can be utilized for wastewater treatment and production of biofuels from the biomass grown on the wastewater. Bio-based nanomaterials have been extensively studied for their employability in the health care, process optimization, water resource management, dealing with environmental pollutants, biosensors, and many others. Bioprospecting of novel biological agents, bio-based products, and bioresource recovery are paving the way for sustainable development as they are providing local solutions for a number of problems.In this proposed book, we start with the introduction to bio-nanotechnological principles and later on discuss bio-based nanomaterials employability for a diverse range of applications from environment to energy to health care. This book provides with current trends in bio-nanotechnology for anthropogonic purposes, prospects, challenges, and way forward.
Biogenic Sedimentary Rocks in a Cold, Cenozoic Ocean: Neritic Southern Australia
by Noel P. James Yvonne BoneThis book documents and interprets the onshore Cenozoic temperate carbonate depositional system along the southern margin of Australia. These strata, deposited in four separate basins, together with the extensive modern marine system offshore, comprise the largest such cool-water carbonate system on the globe. The approach is classic and comparative but the information is a synthesis of recent research and new information. A brief section of introduction outlines the setting, modern comparative sedimentology offshore, and structure of the Cenozoic onshore. The core of the book is a detailed analysis and illustration of the four Eocene to Pleistocene successions. Deposits range from temperate carbonates, to biosiliceous spiculites, to marginal marine siliciclastics. Each unit is interpreted, as much as possible, based on our understanding of the modern offshore depositional system. A subsequent part concentrates on diagenesis both before and after the late Miocene uplift. It turns out that alteration in the two packages is entirely different. The preceding attributes of each succession are then interpreted on the basis of controlling factors such as tectonics, oceanography, climate, and glaciation of nearby Antarctica. This research has revealed new implications for the interpretation of specific attributes of cool-water carbonate sedimentology that could only be discovered from the rock record. Insights concerning cyclicity, reef mounds, biosiliceous deposition, and trophic resources are detailed in the next section. The concluding part focuses on global comparisons, especially the Mediterranean and New Zealand.

Biogeochemical Dynamics at Major River-Coastal Interfaces
by Mead A. Allison Thomas S. Bianchi Thomas S. Bianchi Mead A. Allison Wei-Jun CaiThis volume provides a state-of-the-art summary of biogeochemical dynamics at major river-coastal interfaces for advanced students and researchers. River systems play an important role (via the carbon cycle) in the natural self-regulation of Earth's surface conditions by serving as a major sink for anthropogenic CO2. Approximately 90 percent of global carbon burial occurs in ocean margins, with the majority of this thought to be buried in large delta-front estuaries (LDEs). This book provides information on how humans have altered carbon cycling, sediment dynamics, CO2 budgets, wetland dynamics, and nutrients and trace element cycling at the land-margin interface. Many of the globally important LDEs are discussed across a range of latitudes, elevation and climate in the drainage basin, coastal oceanographic setting, and nature and degree of human alteration. It is this breadth of examination that provides the reader with a comprehensive understanding of the overarching controls on major river biogeochemistry.

Biogeochemical Transformations in the Baltic Sea: Observations Through Carbon Dioxide Glasses (Springer Oceanography)
by Bernd Schneider Jens Daniel MüllerThis book provides a comprehensive review of the biogeochemistry in the Baltic Sea. It is based on the fact that biogeochemical processes that are relevant for the ecological state of the Baltic Sea (and other sea areas), are all in some way related to the production and mineralization of organic matter (biomass) and thus are associated with the consumption or release of CO2. The significant progress with regard to our chemical analytical capabilities concerning the marine CO2 system has facilitated new approaches to study the Baltic Sea biogeochemistry, in particular with regard to a quantitative process understanding. To demonstrate this, the authors present the fundamentals of the marine CO2 system in a theoretically sound, but still intelligible way. This is followed by a comprehensive presentation of our current knowledge about the CO2 system in the Baltic Sea and the implications for our understanding of biogeochemical processes such as production/mineralization of organic matter and the stoichiometry involved, nitrogen fixation, denitrification, and phosphate transformations at varying redox conditions. Finally, the CO2 gas exchange balance and related problems such as acidification are addressed.

Biogeochemistry and the Environment
by Michael O'Neal CampbellBiogeochemistry may be defined as the science that combines biological and chemical perspectives for the examination of the Earth’s surface, including the relations between the biosphere, lithosphere, atmosphere, and hydrosphere. Biogeochemistry is a comparatively recently developed science, that incorporates scientific knowledge and findings, research methodologies, and models linking the biological, chemical, and earth sciences. Therefore, while it is a definitive science with a strong theoretical core, it is also dynamically and broadly interlinked with other sciences. This book examines the complex science of biogeochemistry from a novel perspective, examining its comparatively recent development, while also emphasizing its interlinked relationship with the earth sciences (including the complementary science of geochemistry), the geographical sciences (biogeography, oceanography, geomatics, earth systems science), the biological sciences (ecology, wildlife studies, biological aspects of environmental sciences) and the chemical sciences (including environmental chemistry and pollution). The book covers cutting-edge topics on the science of biogeochemistry, examining its development, structure, interdisciplinary, multidisciplinary, and transdisciplinary relations, and the future of the current complex knowledge systems, especially in the context of technological, developments, and the computer and data fields.
Biogeochemistry of Marine Systems (Sheffield Biological Siences Ser. #20)
by KENNETH D. BLACK; GRAHAM B. SHIMMIELDMarine systems vary in their sensitivities to perturbation. Perturbation may be insidious - such as increasing eutrophication of coastal areas - or it may be dramatic - such as a response to an oil spill or some other accident. Climate change may occur incrementally or it may be abrupt, and ecosystem resilience is likely to be a complex function of the interactions of the factors and species mediating key biogeochemical processes.Biogeochemistry of Marine Systems considers issues of marine system resilience, focusing on a range of marine systems that exemplify major global province types. Each system is interesting in its own right, on account of its sensitivity to natural or anthropogenic change or its importance as an ecological service provider. Each contributing author concentrates on advances of the last decade.This prime reference source for marine biogeochemists, marine ecologists, and global systems scientists provides a strong foundation for the study of the multiple marine systems undergoing change because of natural biochemical or anthropogenic factors.

by Domy C. AdrianoBiogeochemistry of Trace Metals is a compendium of the most recent information available on the effects of trace metals in soil quality and its potential threat on the transfer of these contaminants to consumers. Most of the chapters in the book were presented as papers during the First International Conference on the Biogeochemistry of Trace Elements (formerly Metals in Soils, Plants, Waters, and Animals) held in Orlando, Florida in May, 1990. Topics discussed include background levels of metals in soils and/or plants (covering western Europe; temperate, humid Europe; and the People's Republic of China); metal cycling and transfer in the food chain in agroecosystems; uptake and accumulation of metals by bacteria, fungi, and invertebrates; mechanistic aspects of metals; the microbial aspects of soil selenium losses; and manganese sorption on soil constituents.
Biogeochemistry of Wetlands: Science and Applications
by K. Ramesh Reddy Ronald D. DeLaune Patrick W. InglettThe 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.
Biogeochemistry of a Forested Ecosystem
by Gene E. LikensThe 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.
