| Zusammenfassung |
| Changes in marine phytoplankton communities at short-time scales have rarely
been examined. As a part of the DYNAPROC 2 cruise (14 September–17 October 2004),
conducted in the NW Mediterranean Sea, we daily sampled and determined
taxonomic composition and abundance of the microphytoplankton and the
dominant microzooplanktonic groups from both net and bottle sampling, during
4 cycles of 5 days. Hydrological conditions were characterised by the
dominance of a stratified water column and nutrient-depleted conditions.
However the stratification index revealed a destabilization of the water
column from the beginning of the second cycle, related to a wind stress
event accompanied with coastal water intrusion. This conducted to an
increase of taxonomic richness and a general decrease of evenness, depicting
the dominance of species with the best fitness. We also emphasised on the
great interest of taxonomic studies, as able to provide valuable information
on biogeochemical-important groups of species, potential water masses
indicators and trophic aspects of the community that are ignored or largely
underestimated with other kind of phytoplankton studies, such as pigment
analysis. |
