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.

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: 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.

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.

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.

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.

Biohybrid Systems: Nerves, Interfaces and Machines

by Ranu Jung

The discipline of neurodesign is a highly interdisciplinary one, while at the same time in the process of maturing towards real-life applications. The breakthrough about to be achieved is to close the loop in communication between neural systems and electronic and mechatronic systems and actually let the nervous system adapt to the feedback from the man-made systems. To master this loop, scientists need a sound understanding of neurology, from the cellular to the systems scale, of man-made systems and how to connect the two. These scientists comprise medical scientists, neurologists and physiologists, engineers, as well as biophysicists. And they need the topics in a coherently written work with chapters building upon another.

Biohydrogen - Advances and Processes (Biofuel and Biorefinery Technologies #13)

by Carlos Ricardo Soccol Satinder Kaur Brar Kugenthiren Permaul Kannan Pakshirajan Júlio Cesar de Carvalho

This book presents an introduction to biohydrogen production and the recent advances and developments of the cleanest biofuel produced from bioresources. Biohydrogen has the highest energy content relative to weight and burns cleanly – generating just water. It is the best choice for fuel cells, where it generates electricity directly, in its reaction with oxygen. Biohydrogen occurs naturally as part of digestive gases from mammals and can be produced in specially designed anaerobic biodigesters, or through photocatalysis with microalgae. The gas is also easy to purify and use. The economic production of biohydrogen is still full of challenges: From the efficient and rapid conversion of the substrate to storage, transportation, and safe use, there are several aspects that need to be developed. Research in this field is addressing the issue of efficient large-scale production from several directions: Substrate pretreatment to enhance digestibility, metabolic networks analysis, microbial diversity and succession to highlight constraints in production, bioreactor, and downstream design to improve throughput and reduce costs, to name a few. The ideas and technologies presented in this book contribute to achieving the UN Sustainable Development Goal 7: Affordable and Clean Energy. The book is written for researchers and students interested in biorefinery and biofuel technologies.
