Última Role of environmental factors for the vertical distribution (0-1000 m) of marine bacterial communities in the NW Mediterranean Sea 5 Ghiglione, J. F.; Palacios, C.; Marty, J. C.; Mevel, G.; Labrune, C.; Conan, P.; Pujo-pay, M.; Garcia, N.; Goutx, M.. Bacterioplankton plays a central role in energy and matter fluxes in the sea, yet the factors that constrain its variation in marine systems are still poorly understood. Here we use the explanatory power of direct multivariate gradient analysis to evaluate the driving forces exerted by environmental parameters on bacterial community distribution in the water column. We gathered and analysed data from a one month sampling period from the surface to 1000m depth at the JGOFS-DYFAMED station (NW Mediterranean Sea). This station is characterized by very poor horizontal advection currents which makes it an ideal model to test hypotheses on the causes of vertical stratification of bacterial communities. Capillary electrophoresis single strand conformation...

C.; Goutx, M.; Guigue, C.; Leblond, N.; Raimbault, P.. Short-term changes in the flux of particulate matter were determined in the central north western Mediterranean Sea (near DYFAMED site) using drifting sediment traps at 200 m depth in the course of the DYNAPROC 2 cruise (14 September-17 October 2004). In this period of marked water column stratification, POC fluxes varied by an order of magnitude, in the range of 0.03-0.29 mgC m(-2) h(-1) over the month and showed very rapid and high variations. Particulate carbon export represented less than 5% of integrated primary production, suggesting that phytoplankton production was essentially sustained by internal recycling of organic matter and retained within the photic zone. While PON and POP fluxes paralleled one another, the elemental ratios POC/PON and...
