Food-chain relationships in subtidal silty sand marine sediments and the role of meiofauna in stimulating bacterial productivity

  title={Food-chain relationships in subtidal silty sand marine sediments and the role of meiofauna in stimulating bacterial productivity},
  author={Sebastian A. Gerlach},
From bibliographic data the biomass correlations (organic dry weight) are constructed for the subsurface layer of a hypothetical 30 m deep silty sand station: 200 μg/ml macrofauna (including 120 μg/ml subsurface deposit feeders), 50 μg/ml meiofauna, 20 μg/ml Foraminifera, 1 μg/ml Ciliata and Flagellata, and 100 μg/ml bacteria. ATP-biomass is discussed. Meiofauna and Foraminifera contribute with 30 and 12% to the living biomass in the sediment, and it is assumed that their contribution to the… CONTINUE READING
