Biogeochemical Dynamics at Major River-Coastal Interfaces

by Mead A. Allison Thomas S. Bianchi Thomas S. Bianchi Mead A. Allison Wei-Jun Cai

This 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 Müller

This 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 of Marine Systems (Sheffield Biological Siences Ser. #20)

by KENNETH D. BLACK; GRAHAM B. SHIMMIELD

Marine 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.

Biogeochemistry of Wetlands: Science and Applications

by K. Ramesh Reddy Ronald D. DeLaune Patrick W. Inglett

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.

Biogeochemistry of a Forested Ecosystem

by Gene E. Likens

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.

Biogeochemistry of the Atmosphere, Ice and Water of the White Sea: The White Sea Environment Part I (The Handbook of Environmental Chemistry #81)

by Alexander P. Lisitsyn Viacheslav V. Gordeev

This book is devoted to the biogeochemical environment of the White Sea, an inland sea in the Northwestern region of Russia. It provides a comprehensive review and discusses the latest research findings on the oceanology, sedimentology and biogeochemistry of the White Sea water column. The topics discussed include the regulation of the physico-geographical conditions in the White Sea basin; dispersed sedimentary substance of the atmosphere and the cryosphere; the geochemical peculiarities of the river discharge into the White Sea; and the phyto- and zooplankton activities in the White Sea. Taking the biggest river in the White Sea basin as an example, the authors closely examine the deposition of suspended particulate matter, the biogeochemical behaviour of dissolved and suspended forms of organic material and the significant group of chemical elements in the river-sea mixing zone of the Severnaya Dvina River. The book ends with a summary of the key conclusions and recommendations. Together with the companion volume Sedimentation Processes in the White Sea: The White Sea Environment Part II, it offers an essential source of information for postgraduate students, researchers and stakeholders alike.

Biogeographic Patterns of South American Anurans

by Tiago S. Vasconcelos Fernando R. da Silva Tiago G. dos Santos Vitor H. Prado Diogo B. Provete

This book analyzes different facets of anuran amphibian distribution in South America. We integrate alternative biological metrics employing cutting-edge methods to understand the dynamic processes underlying species distribution patterns. By using the modern biogeographic toolbox, we explore how richness gradients, phylogenetic diversity, functional diversity, and range size/endemism distribution of amphibians vary along the continent. Moreover, we present a robust proposal for priority areas for conservation of anurans in South America that maximizes representativeness of distinct biodiversity facets.

Biogeography and Evolution in New Zealand (CRC Biogeography Series #1)

by Michael Heads

Biogeography and Evolution in New Zealand provides the first in-depth treatment of the biogeography of New Zealand, a region that has been a place of long-enduring interest to ecologists, evolutionary scientists, geographers, geologists, and scientists in related disciplines. It serves as a key addition to the contemporary discussion on regionalization—how is New Zealand different from the rest of the world? With what other areas does it share its geology, history, and biota? Do new molecular phylogenies show that New Zealand may be seen as a biological ‘parallel universe’ within global evolution?

Biogeography of Australasia

by Michael Heads

Over the last decade, molecular studies carried out on the Australasian biota have revealed a new world of organic structure that exists from submicroscopic to continental scale. Furthermore, in studies of global biogeography and evolution, DNA sequencing has shown that many large groups, such as flowering plants, passerine birds and squamates, have their basal components in this area. Using examples ranging from kangaroos and platypuses to kiwis and birds of paradise, the book examines the patterns of distribution and evolution of Australasian biodiversity and explains them with reference to tectonic and climatic change in the region. The surprising results from molecular biogeography demonstrate that an understanding of evolution in Australasia is essential for understanding the development of modern life on Earth. A milestone in the literature on this subject, this book will be a valuable source of reference for students and researchers in biogeography, biodiversity, ecology and conservation.

Biogeography of Mycorrhizal Symbiosis (Ecological Studies #230)

by Leho Tedersoo

This book offers a timely overview and synthesis of biogeographic patterns of plants and fungi and their mycorrhizal associations across geographic scales. Written by leading experts in the field, it provides an updated definition of mycorrhizal types and establishes the best practices of modern biogeographic analyses. Individual chapters address the basic processes and mechanisms driving community ecology, population biology and dispersal in mycorrhizal fungi, which differ greatly from these of prokaryotes, plants and animals. Other chapters review the state-of-the-art knowledge about the distribution, ecology and biogeography of all mycorrhizal types and the most important fungal groups involved in mycorrhizal symbiosis. The book argues that molecular methods have revolutionized our understanding of the ecology and biogeography of mycorrhizal symbiosis and that rapidly evolving high-throughput identification and genomics tools will provide unprecedented information about the structure and functioning of mycorrhizal symbiosis on a global scale. This volume appeals to scientists in the fields of plant and fungal ecology and biogeography.

Biogeography of the Quaternary Molluscs of the Southwestern Atlantic Ocean (SpringerBriefs in Earth System Sciences)

by Sergio Martínez Claudia J. del Río Alejandra Rojas

The Quaternary comprises a brief time in the Earth's history, and apart from a few exceptions, molluscan assemblages recovered from exposures along the coast of Southwestern South America (Southern Brazil, Uruguay, Argentina) are essentially the same than those that inhabit the region today, leading to the assumption that no important change in the distribution of the faunas since Pleistocene times has occurred. However, the good taxonomic and temporal resolution reached in the last years, allowed us to detect some biogeographic changes, although traditional biogeographic units remain the same (i.e. Magellanic and Argentinean Provinces). These modifications involve mainly variations in the taxonomic composition of the assemblages and in the southern boundaries of some species distributions (extralimital species), today retracted northwards. These changes are related to southward shifts of the warm waters of the Brazilian Current, correlated with global warm peaks. This phenomenon was more intense in the Late Pleistocene (MIS 5e) and in the Holocene between ca. 6500-3500 14C yr.

Biogeography: An Integrative Approach of the Evolution of Living

by Eric Guilbert

The recent progress in analytical methods, aided by bringing in a wide range of other disciplines, opens up the study to a broader field, which means that biogeography now goes far beyond a simple description of the distribution of living species on Earth.Originating with Alexander von Humboldt, biogeography is a discipline in which ecologists and evolutionists aim to understand the way that living species are organized in connection with their environments. Today, as we face major challenges such as global warming, massive species extinction and devastating pandemics, biogeography offers hypotheses and explanations that may help to provide solutions.This book presents as wide an overview as possible of the different fields that biogeography interacts with. Sixteen authors from all over the world offer different approaches based on their specific areas of knowledge and experience; thus, we intend to illustrate the vast number of diverse aspects covered by biogeography.

Biographical History of Behavioral Neuroendocrinology

by Randy J. Nelson Zachary M. Weil

Behavioral neuroendocrinologists are interested in the interactions between hormones and behaviors. This unique book tracks the development of behavioral neuroendocrinology from the first recognized paper in the field by Arnold Berthold in 1849 to the major contributors of the past century. It traces the history and development of the field by exploring the women and men who conducted the studies that revealed these hormone-behavioral relationships. Most chapters are written by the individuals who knew these pioneers best, and describe their stories and discuss the ways in which their work has shaped the field. Now is the perfect time for this book. The field is burgeoning and interest in the development of theoretical perspectives is thriving. Moreover, although this field was dominated by men early on, it has become a field with near sexual parity among its faculty, society membership, and leadership, and thus serves as an example of equitable science, training, and advocacy.

Biographies in the History of Physics: Actors, Objects, Institutions

by Mark Walker Christian Forstner

This book sheds new light on the biographical approach in the history of physics by including the biographies of scientific objects, institutions, and concepts. What is a biography? Can biographies also be written for non-human subjects like scientific instruments, institutions or concepts? The respective chapters of this book discuss these controversial questions using examples from the history of physics. By approaching biography as metaphor, it transcends the boundaries between various perspectives on the history of physics, and enriches our grasp of the past.

Biography of Resistance: The Epic Battle Between People and Pathogens

by Muhammad H. Zaman

Award-winning Boston University educator and researcher Muhammad H. Zaman provides a chilling look at the rise of antibiotic-resistant superbugs, explaining how we got here and what we must do to address this growing global health crisis.In September 2016, a woman in Nevada became the first known case in the U.S. of a person who died of an infection resistant to every antibiotic available. Her death is the worst nightmare of infectious disease doctors and public health professionals. While bacteria live within us and are essential for our health, some strains can kill us. As bacteria continue to mutate, becoming increasingly resistant to known antibiotics, we are likely to face a public health crisis of unimaginable proportions. “It will be like the great plague of the middle ages, the influenza pandemic of 1918, the AIDS crisis of the 1990s, and the Ebola epidemic of 2014 all combined into a single threat,” Muhammad H. Zaman warns.The Biography of Resistance is Zaman’s riveting and timely look at why and how microbes are becoming superbugs. It is a story of science and evolution that looks to history, culture, attitudes and our own individual choices and collective human behavior. Following the trail of resistant bacteria from previously uncontacted tribes in the Amazon to the isolated islands in the Arctic, from the urban slums of Karachi to the wilderness of the Australian outback, Zaman examines the myriad factors contributing to this unfolding health crisis—including war, greed, natural disasters, and germophobia—to the culprits driving it: pharmaceutical companies, farmers, industrialists, doctors, governments, and ordinary people, all whose choices are pushing us closer to catastrophe.Joining the ranks of acclaimed works like Microbe Hunters, The Emperor of All Maladies, and Spillover, A Biography of Resistance is a riveting and chilling tale from a natural storyteller on the front lines, and a clarion call to address the biggest public health threat of our time.
