Abstract

Marine zooplankton are a diverse group of organisms. Different species have different foraging strategies, life cycles, patterns of diel vertical migration, etc. Reducing such complexity to a minimal number of compartments in large-scale ecosystem models therefore poses a significant problem. The working group concentrated their discussions on the following topics, each of which need to be considered when tackling this problem:
  1. (i)

    The functional roles of Zooplankton in the marine food web. If different types of Zooplankton are responsible for different system processes, then they would probably have to be modelled as separate entities.

     
  2. (ii)

    Model structure. A suitable structure must be designed to incorporate different functional groups and trophic levels. Factors influencing whether different groups of Zooplankton should be modelled explicitly (as state variables) or implicitly (in the model equations) are discussed.

     
  3. (iii)

    Complexity within functional groups. A major difficulty when constructing large-scale ecosystem models is the derivation of universal parameters for Zooplankton, because of the enormous variety of species that occurs in the ocean. This variety is investigated in some detail, so as to provide insight into the modelling difficulties involved. Recommendations can then be made on how future modelling research can proceed.
