Ecology of the macroinvertebrate communities in Mediterranean rivers at different scales and organization levels

The main objective of this work has been to determine the structure of the macroinvertebrate communities in mediterranean rivers at different scales, organization and taxonomical levels. To achieve that, an appropriated sampling methodology for macroinvertebrate studies has been developed. Physical...
