Abstract : Coastal tidal sediments are highly dynamic environments inhabited by phototrophic biofilms. These are dominated by microalgae, but are also characterized by high densities and biodiversity of protozoa, bacteria and invertebrates. The biofilms drive and modulate rapid carbon fluxes, which fuel the coastal food web. To quantify the contribution of the different organisms to these fluxes, we labelled a sandy and a muddy site in Baie de Bourgneuf (France) with inorganic carbon-13 in a pulse-chase experiment. The carbon flow was followed over several tidal cycles using RNA-Stable Isotope Probing and by measuring carbon-13 enrichment in fatty acids, meiofauna and macrofauna. At the same time, the diversity of the different trophic compartments was described in detail using SSU rDNA and RNA amplicon sequencing and microscopy. Primary production, respiration and the production of extracellular polymeric substances were also quantified. The inorganic carbon was rapidly taken up in both sites by the benthic microalgae after which it was also incorporated in the other organisms. The carbon-13 was almost completely lost in the sandy site after two tidal cycles, whilst it was still retained in the muddy sediment after five days, illustrating the pronounced difference in carbon flows between muddy and sandy sediments. The relationship between the carbon fluxes and the biodiversity of the biofilms will be presented in the poster.
