Biosphere, relatively thin life-supporting stratum of Earth’s surface, extending from a few kilometers into the atmosphere to the ocean’s deep-sea vents. This global ecosystem continuously cycles matter. It is composed of organisms (biota) and the abio
Deep biosphereGeomycologyOceanic crustA major part of the biologic activity on Earth is hidden underneath our feet in an environment coined the deep biosphere which stretches several kilometers down into the bedrock. The knowledge about life in this vast energy-poor deep system is, however, ...
Recent studies of the geological record of cyclic chemical changes in the earth atmosphere, oceans, and biosphere are discussed in reviews contributed by leading experts. Topics addressed include the history of geochemical science and the study of cyclic processes, geochemical cycles in the ...
Fungi play important roles in the cycling of elements in the biosphere but are frequently neglected within microbiological and geochemical research spheres. Symbiotic mycorrhizal fungi are responsible for major transformations and redistribution of inorganic nutrients, while free-living fungi have major roles...
Fungi have important roles in the cycling of elements in the biosphere. Symbiotic mycorrhizal fungi are responsible for major transformations and redistribution of inorganic nutrients, while free-living fungi have major roles in the decomposition of organic materials, including xenobiotics. Fungi are also...
What are Nutrients? Nutrients are chemicals required for growth and other life processes. Nutrients move through the biosphere in nutrient cycles or exchanges. Nutrient Cycle AKA Biogeochemical Cycle The flow of a nutrient from the environment to living organisms and back to the environment Main reser...
Water cycle through the various aspects of the atmosphere, hydrosphere, lithosphere and biosphere linked with each other, and the energy exchange between them; water entrained in the movement of dissolved substances and sediment leaving the mass transfer; movement through the water cycle, so that al...

supporting deep biosphere metabolisms. As carbon in trench sediments eventually enters the subduction zone system during plate convergence1, the transformations of SOC, DOC, DIC, and methane may influence the carbon exchange among the Earth’s surface biosphere, the lithosphere, and even the mantle17...
These processes, manifestations of diverse and highly evolved cellular mechanisms catalyzed by Bacteria and Archaea, maintain the biosphere. Progress in biogeochemistry relies upon the underlying science of environmental microbiology. Over the last 2 years, important discoveries have advanced the ecological,...
