Research
My research relates to the question: How can we explain the diversity, the composition and the distribution of zoo plankton in estuary dynamic ecosystems? The dynamics of the estuary community depend on biotic and abiotic processes that act on different scales, spatial and temporal, from the individual to the community. My work integrates itself into this concept through (1) Life history traits, population dynamics and secondary production of copepods and mysidacea (2) trophic relations, (3) intraspecific biodiversity and genetic diversity, (4) biology/physical coupling, (5) and disturbances (invasive species).
