Devenir des bactéries dans les réseaux trophiques des vasières intertidales : le cas de brouage (Baie de Marennes-Oléron)
Provedor de dados: 5
Autores: Pascal, Pierre-yves.
Bacteria are highly abundant and productive in intertidal mudflat sediments. By analogy  with pelagic system, it has been suggested that bacteria play an important role in benthic food  web. Due to technical difficulties, numbers of studies dealing with benthic bacterivory are not  numerous and give conflicting results. A method using community of 15N enriched bacteria as  tracer was developed in order to measure grazing of meiofauna and macrofauna. Since enriched  bacteria present characteristics of size, activity and diversity close to natural ones, bias due to  selective bacterial ingestion by grazers are limited. Due to tidal cycles, intertidal mudflat  constitutes highly variable environment at short time scale. Since those variations may influence...
