Abstract

The responses of 32 Hydraenidae and Elmidae species to six chemical parameters - alkalinity, Cl-, SO4 --, COD, NO3 - and total P have been analysed in the Orbigo river basin. The study of the distribution in relation to these factors by means of elaborating their ecological profiles pointed out the indicator species for each one of these parameters, according to their reciprocal species-factor information.
