Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been an effort to include the effects of biotic, as well as abiotic variables, in studies of ecosystem function. In marine benthic systems, numerous studies have identified a link between bioturbation and ecosystem function, the nature of which varies with invertebrate species identity, diversity, behaviour, environmental context and other traits. Despite clear links between invertebrate activity, ecosystem function and the biogeochemical properties of sediments that have been well documented over a number of years, relatively little is known about the mechanisms by which microbially mediated processes are affected by invertebrates. Without this knowledge, the variations in ecosystem function observed under different conditions cannot be explained and the relationship between biodiversity and ecosystem function cannot be fully understood. Nitrogen cycling is of particular interest since in marine systems primary productivity is often limited by N availability and nitrogen also interacts with other nutrient cycles.

Book excerpt: Marine sediments support complex interactions between macro-and microorganisms that have global implications for carbon and nutrient cycles. What is the state of the science on such interactions from coastal and estuarine environments to the deep sea? How does such knowledge effect environmental management? And what does future research hold in store for scientists, engineers, resource managers, and educators?Interactions between Macro- and Microorganisms in Marine Sediments responds to these questions, and more, by focusing on:? Interactions between plants, microorganisms, and marine sediment? Interactions between animals, microorganisms, and marine sediment? Interactions between macro- and microorganisms and the structuring of benthic communities? Impact of macrobenthic activity on microbially-mediated geochemical cycles in sediments? Conceptual and numeric models of diagenesis that incorporate interactions between macro- and microorganismsHere is an authoritative overview of the research, experimentation and modeling approaches now in use in our rapidly evolving understanding of life in marine sediments.

Book Synopsis Nitrogen in the Marine Environment by : Edward J. Carpenter

Download or read book Nitrogen in the Marine Environment written by Edward J. Carpenter. This book was released on 2013-10-22. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Marine Environment provides information pertinent to the many aspects of the nitrogen cycle. This book presents the advances in ocean productivity research, with emphasis on the role of microbes in nitrogen transformations with excursions to higher trophic levels. Organized into 24 chapters, this book begins with an overview of the abundance and distribution of the various forms of nitrogen in a number of estuaries. This text then provides a comparison of the nitrogen cycling of various ecosystems within the marine environment. Other chapters consider chemical distributions and methodology as an aid to those entering the field. This book discusses as well the enzymology of the initial steps of inorganic nitrogen assimilation. The final chapter deals with the philosophy and application of modeling as an investigative method in basic research on nitrogen dynamics in coastal and open-ocean marine environments. This book is a valuable resource for plant biochemists, microbiologists, aquatic ecologists, and bacteriologists.

Book Synopsis Nitrogen Cycling in Coastal Marine Environments by : T. Henry Blackburn

Download or read book Nitrogen Cycling in Coastal Marine Environments written by T. Henry Blackburn. This book was released on 1988-03-21. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen discharge to the coastal environment has been increasing, posing the threat of accelerated eutrofication. Considerable research has been conducted in recent years to examine the impact of the nitrogen loading in coastal ecosystems. Based on proceedings from a SCOPE symposium held at the University of Aarhus in July of 1985, this volume covers a variety of up-to-date developments in research on nitrogen cycling in coastal marine environments. Topics include the role of nitrogen in algal productivity, regeneration of nutrients in the water column and the sediments, and the flow of nitrogen in coastal ecosystems.

Book Synopsis The Chemistry of Microbiomes by : National Academies of Sciences, Engineering, and Medicine

Download or read book The Chemistry of Microbiomes written by National Academies of Sciences, Engineering, and Medicine. This book was released on 2017-07-19. Available in PDF, EPUB and Kindle. Book excerpt: The 21st century has witnessed a complete revolution in the understanding and description of bacteria in eco- systems and microbial assemblages, and how they are regulated by complex interactions among microbes, hosts, and environments. The human organism is no longer considered a monolithic assembly of tissues, but is instead a true ecosystem composed of human cells, bacteria, fungi, algae, and viruses. As such, humans are not unlike other complex ecosystems containing microbial assemblages observed in the marine and earth environments. They all share a basic functional principle: Chemical communication is the universal language that allows such groups to properly function together. These chemical networks regulate interactions like metabolic exchange, antibiosis and symbiosis, and communication. The National Academies of Sciences, Engineering, and Medicine's Chemical Sciences Roundtable organized a series of four seminars in the autumn of 2016 to explore the current advances, opportunities, and challenges toward unveiling this "chemical dark matter" and its role in the regulation and function of different ecosystems. The first three focused on specific ecosystemsâ€"earth, marine, and humanâ€"and the last on all microbiome systems. This publication summarizes the presentations and discussions from the seminars.
