Topic Editors: Anke Marianne Herrman, Doug LaRowe, Alain F. Plante. 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 and allow the delivery of a wide range of life-supporting ecosystem services. The aim of this Research Topic is to gather contributions from scientists working in diverse disciplines who have a common interest in evaluating bioenergetics at various spatial and temporal scales in a variety of different environments. The spatial scales range from the process and organismal level up to ecosystems, the temporal scales range from the near-instantaneous to the millennial, and the scientific disciplines involved include: soil scientists, biogeochemists, organic geochemists, microbial and ecosystem ecologists etc. Articles can be original research, techniques, reviews or synthesis papers. We encourage manuscripts focusing on interdisciplinary interactions addressing both basic and applied research as well as associated theoretical work. The overarching goal of this Research Topic is to demonstrate the environmental breadth of bioenergetics, and foster understanding between different scientific communities who may not always be aware of one another’s work. Abstract submission deadline: June 30, 2017.
