Resumen:
Phytoplankton and environmental variables were studied during a year in a shallow eutrophic lake and its
inflow in the ?depressed Pampa? of Argentina. The taxa were classified according to the competitors,
stress tolerators, ruderals and intermediate categories (CSR) model and were allocated to morphofunctional
groups (MFG). As was expected according to the trophic state, scarce transparency and
mixing condition, the R-strategists (several cyanobacteria and pennate diatoms) dominated almost all of
the study period. C-strategists were more scarce and favoured by short periods of transparency, whereas
only three species were attributed to the S-strategist category. Each MFG was represented by a single
species at a time, resulting in a high functional miscellany in this shallow lake. Thus, we can assume that
the CSR approach is a useful tool to explain the success of the different species of phytoplankton in this
shallow lake.
