Book Synopsis Interactions Between Macro- and Microorganisms in Marine Sediments by :
Download or read book Interactions Between Macro- and Microorganisms in Marine Sediments written by . This book was released on 2005-01-14. Available in PDF, EPUB and Kindle. 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 Interactions Between Macro- and Microorganisms and the Effects on Nitrogen Cycling in Marine Sediments by :
Download or read book Interactions Between Macro- and Microorganisms and the Effects on Nitrogen Cycling in Marine Sediments written by . This book was released on 2013. 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 Synopsis Metabolic Interactions Between Bacteria and Phytoplankton by : Xavier Mayali
Download or read book Metabolic Interactions Between Bacteria and Phytoplankton written by Xavier Mayali. This book was released on 2018-06-06. Available in PDF, EPUB and Kindle. Book excerpt: The cycling of energy and elements in aquatic environments is controlled by the interaction of autotrophic and heterotrophic processes. In surface waters of lakes, rivers, and oceans, photosynthetic microalgae and cyanobacteria fix carbon dioxide into organic matter that is then metabolized by heterotrophic bacteria (and perhaps archaea). Nutrients are remineralized by heterotrophic processes and subsequently enable phototrophs to grow. The organisms that comprise these two major ecological guilds are numerous in both numbers and in their genetic diversity, leading to a vast array of physiological and chemical responses to their environment and to each other. Interactions between bacteria and phytoplankton range from obligate to facultative, as well as from mutualistic to parasitic, and can be mediated by cell-to-cell attachment or through the release of chemicals. The contributions to this Research Topic investigate direct or indirect interactions between bacteria and phytoplankton using chemical, physiological, and/or genetic approaches. Topics include nutrient and vitamin acquisition, algal pathogenesis, microbial community structure during algal blooms or in algal aquaculture ponds, cell-cell interactions, chemical exudation, signaling molecules, and nitrogen exchange. These studies span true symbiosis where the interaction is evolutionarily derived, as well as those of indirect interactions such as bacterial incorporation of phytoplankton-produced organic matter and man-made synthetic symbiosis/synthetic mutualism.
