BN002:
Advances in Aquatic Respiration: New Ideas, Conceptual Models, and Recent Findings on Plankton Community Respiration


Session ID#: 28174

Session Description:
Plankton respiration is controlled by the respiratory electron transport activity in eukaryotic mitochondria and prokaryotic cell membranes. It is driven by the degradation of dissolved and particulate organic carbon, consuming oxygen, generating carbon dioxide, and producing energy in the form of ATP. In the oceans, plankton respiration defines the biological carbon pump, the microbial carbon pump, heterotrophic energy production, nutrient retention efficiency, carbon flux transfer efficiency, carbon sequestration, carbon burial, and evasion of CO2 to the atmosphere, and plays a major role in ocean acidification, ocean deoxygenation and coastal hypoxia. In lakes and rivers, plankton respiration constitutes an important driver of atmospheric CO2 emissions and defines the metabolic balance of production to respiration or net ecosystem production. Yet the state and variability of plankton respiration, apportionment to plankton 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 plankton respiration might change on a range of time and space scales in a multi-stressor world.

This session invites contributions which discuss the role of plankton community respiration in aquatic research (from lakes to the open ocean), at cellular to ecosystem and second to seasonal scales.
