| Zusammenfassung |
| We investigate the competition between two different functional groups of
phytoplankton in the wake of an island close to a coastal upwelling region.
We couple a simple biological model with three trophic levels and a
hydrodynamic model of a von Kármán vortex street. The spatio-temporal
abundance shows that the different phytoplankton groups dominate in different
regions of the flow. The composition of the phytoplankton community varies
e.g. for the different vortices. We study the mechanism leading to these
inhomogeneous dominance patterns by investigating the nutrient transport in
the flow and the interplay of hydrodynamic and biological time scales. |
