ME41A:
Zooplankton Productivity as a Function of Trophodynamics in Marine Ecosystems I


Session ID#: 37354

Session Description:
The functional role of zooplankton communities in marine food-webs represents an effective integration of material/energy transfers through multiple lower trophic level interactions (phytoplankton and the microbial loop) toward animals at higher trophic levels. Zooplankton productivity represents an overarching functional measure of this critical role and has been emphasized as important to our understanding of how fishery resources respond to cyclical regime shifts and longer-term responses of marine ecosystems to global climate change. However, evaluation of zooplankton productivity and its controlling factors in the field is still challenging because of the necessity of broad coverage applicable to multiple phyla and trophic levels, with high temporal and spatial resolution.

This session will share the information on zooplankton productivity measured by various contemporary methods and relevant applications including transfer efficiency and relationships to biogeochemistry and fisheries production. We also welcome theoretical and methodological topics such as comparison and applicability of existing methods as well as the development of novel methods. Through this session, we would like to foster a cooperative network and research activities for zooplankton production measurements and methodologies among members of the PICES and ICES communities.
