| Two simulated oil-spills in the Mahakam delta revealed the consequences of this type of pollution on the site's main benthic populations. The results of these trials differentiated between short-term (high toxicity similar to chemical pollution) and long-term effects (similar to organic pollution) of hydrocarbons. Two factors affected the distribution of the main macrofaunal species: intertidal height and degree of pollution. The latter was measured either by the initial quantity of oil spilled or by concentrations measured at each sampling. These trials also showed that dispersants were inefficient and that dredging treatments did not yield positive results. Often no treatment was preferable to these two treatments. A global statistical analysis was... |

| A steady-state energy flow model is proposed for the benthic fine sand community of the Bay of Saint-Brieuc. The main objective is to assess the relative importance of benthic processes associated with the carbon cycle in an eutrophicated bay. Available data include biomass estimates of the major trophic groups and measurements of the most critical fluxes : particulate organic carbon sedimentation, community respiration, microbial production. A balanced annual carbon budget is estimated using an inverse method, particularly appropriate in food web research where the number of unknowns is far higher than the number of independent observations. The method offers the possibility of taking dynamical constraints into account, by introducing global flow... |
