B11A:
Bioenergetics as a Driver of Biogeochemical Processes and Cycling I Posters

Submit an Abstract to this Session



Session ID#: 23435

Session Description:
Energy is continuously transformed in the environment through the metabolic activities of organisms. These transformations of energy, i.e. bioenergetics, underpin most biogeochemical cycles on Earth, allow the delivery of a wide range of life-supporting ecosystem services, and may represent a common currency for multi-elemental analyses. Recent bioenergetics analyses of natural systems represent significant progress in the field of biogeochemistry, and there is increasing interest in using bioenergetics tools to better characterize biogeochemical cycling in water, soils and sediments in terrestrial, freshwater and marine ecosystems. We seek submissions that demonstrate the environmental breadth of bioenergetics at various spatial and temporal scales in a variety of different environments, and foster understanding between different scientific communities who may not always be aware of one another’s work.
