BN23A:
Advances in Aquatic Respiration and Animal Impacts on Nutrient, Oxygen, and Carbon Cycling I


Session ID#: 37675

Session Description:
Aquatic biogeochemistry is fuelled by photosynthesis, but the results for nutrient, carbon and oxygen cycling depend strongly on where and how fast the respiration of photosynthetically-derived organic matter occurs. Plankton respiration is rapid, and is controlled by the respiratory electron transport activity in eukaryotic mitochondria and prokaryotic cell membranes. Animals operate at much slower metabolic rates, but can also have important impacts by modifying microbial populations through trophic cascades, by consuming, modifying and producing organic particles, and through the direct transport of chemicals within their bodies via swimming. Despite its importance, the state and variability of community respiration, the apportionment between functional groups and inter-relationships between organic carbon, community structure and respiration remain loosely constrained, meaning that we lack the capability to model and predict how the respiration of aquatic communities might change on a range of time and space scales in a multi-stressor world. We invite a broad range of contributions that explore, quantify, or otherwise constrain the community respiration by aquatic ecosystems and their biogeochemical impacts, from plankton to large animals.
