The role of zooplankton in biogeochemical cycles

Zooplankton play an integral role in the cycling
of elements in the sea. As key drivers of the biological pump, zooplankton
feed in surface waters and produce sinking fecal pellets, and actively
transport dissolved and particulate matter to depth via vertical migration.
Zooplankton grazing and metabolism transforms particulate organic matter
into dissolved forms, affecting primary producer populations, microbial
remineralization, and particle export to the ocean’s interior.
The elemental stoichiometry of zooplankton and their prey often differ,
resulting in non-Redfieldcycling of C, N and P. We invite papers on
role of zooplankton (both metazoan and protozoan) in biogeochemical
cycles reflectingthe significantstrides that have been made in this
area, as well as identifying crucial gaps in our knowledge. Topics may
include, but are not limited to: the role of zooplankton in the biological
pump, mesopelagic and deep sea processes, trophic interactions and nutrient
cycling, ecological stoichiometry, effects on biogeochemical cycling
(measured or modeled) of human or climate influencedchanges in zooplankton
community structure, and regional comparisons or global syntheses of
the importance of zooplankton in biogeochemical cycles. This session
theme is closely related to research goals within IMBER (Integrated
Marine Biogeochemistry and Ecosystem Research).
