Abstract(1) Continental runoff iInported considerable amounts of silt and organic matter during a short time-period into Alfacs Bay (Ebro Delta) affecting mainly the northern-central parts of the Bay. This eutrophication process coincided with the differcntiation of nClnatode c()fnmunities in the Bay. (2) The species of the affected zone were characterised by having slnooth or only finely striated cuticles, short cephalic setae, few s(unatic setae, emd Inost of theln were epigrowth fecders. (3) The species of the non-affected zone were chartlcterised by their strongly striated cuticles, thc cephalic setae that were longer than in the species of the affected zone and the presence of a large number of sOlnatic setae. Moreover, a great nUlnher of the species in this zone were olnnivores or predators even though the epigrowth feeders were well representcd.
