Temporal and spatial variation of macrozoobenthic communities along the Rio Bunnari was studied. Three areas were sampled according to E.B.I. index method in autumn and spring. In the high and down stream a notable number of taxa was present, whereas in the medium zone, down of the artificial lake, most stenoecious taxa desappeared. This fact could be related to the high eutrophication level of the lake that represents a local limited environmental disturbance. Down stream of this zone the presence of a rich macrozoobenthic community showed its notable potentialities of homeostasis evidenced also by the biotic index.
