The succession in time of different ecological groups along a gradient of organic enrichments was studied 3 years after the Amoco Cadiz oil spill in 2 adjacent tidal inlets or abers. From the results, time patterns are established, through which the ecosystem evolves towards a new equilibrium or back to a former one. In a first stage both pollution sensitive and tolerant species were wiped out as a result of the high toxicity of the kind of oil involved. Once the level of contamination was somewhat stabilized, an opportunistic fauna developed that eventually was overtaken by a community of pollution tolerant species. The latter exhibited an excessive development before a new equilibrium was reached. Differences in the rate of this temporal succession were found between the abers, dependent on the intensity of hydrodynamic processes. Nearly 3 years after the oil spill, most communities had still not reached equilibrium.
