ECOLOGY OF REGULATED STREAMS IN SPAIN: AN OVERVIEW

A brief review of the main studies on flow regulation effects in Spain is presented, considering algae, fish and macroinver-tebrate communities. The eel (Anguilla anguilla), salmon (Salmo salar-) and seatrout (Salmo frutta tr-utta) are perhaps the most affected species, having reduced their distribu...

Description
Summary:A brief review of the main studies on flow regulation effects in Spain is presented, considering algae, fish and macroinver-tebrate communities. The eel (Anguilla anguilla), salmon (Salmo salar-) and seatrout (Salmo frutta tr-utta) are perhaps the most affected species, having reduced their distribution area considerably. The response of macroinvertebrate communities to flow regulation chan-ges from one river to another, due to the multiple use of reservoirs. A decrease of species richness and diversity have been frequently reported, being flow fluctuation and lower water temperature the main factors responsible for that.
