Effects of water abstraction and pollution on macroinvertebrate community in a Mediterranean river

Abstract:

The Llobregat is a Mediterranean river interrupted along its channel by a series of small dams which serve to divert water, and as a result of which, there are daily changes and severe reductions in discharge in many reaches of the river. Its watershed is, moreover, densely populated and industrialized with many point and diffuse pollution sources. Macroinvertebrate community was studied at three stations located in the middle reach of the Llobregat river during spring of 1991, 1993 and 1994 in order to observe the effect of reduced discharge and point-source pollution. A highly significant reduction of macroinvertebrate density and taxon number was observed at the disturbed stations. This pattern was similar for the most sensitive families. Erpobdellidae and Ancylidae were the only families favoured by the altered conditions. © Asociación Española de Limnología.
