The field of aquatic ecosystem modelling has been active since the late 1970s, and in recent decades the models have grown in complexity in terms of ecosystem components and included processes. However, the complexity in ecosystem conceptualizations generally comes at the expense of simple or no hydrodynamic representation, in particular for ecosystem models where higher trophic levels, such as fish, are included. On the other hand, physically resolved hydrodynamic models often include none or only simple representations of ecosystem dynamics. To overcome this discrepancy in complexity between the ecosystem representation and the physical environment, we implemented PCLake within FABM, a Framework for Aquatic Biogeochemical Models. The framework readily enables dynamic coupling of the ecosystem processed in PCLake with a selection of physical environment representations ranging from 0D to 3D hydrodynamics. To test the hypothesis that the physical environment may induce strong influence on ecosystem processes, we applied and compared PCLake applications, with the same standard ecosystem model parameterization, for three different physical environment representations of the same volume of water body in 0D, 1D and 3D, respectively.
