Els macroinvertebrats aquàtics dels ecosistemes fluvials.

Despite covering only 0.8% of the Earth's surface, freshwater biodiversity accounts for 9.5% of all described species. Aquatic macroinvertebrates, and in particular aquatic insects, are one of the most diverse faunal groups of fluvial ecosystems. Macroinvertebates are benthic invertebrates meas...
