Abstract
Macroinvertebrates were sampled from summer 2006 until spring 2008 in the Du River basin in subtropical northern Vietnam. Seventy taxa were identified, which were dominated by aquatic insects, with Diptera, Hemiptera, Ephemeroptera, and Odonata being the orders with the highest diversities. Overall, macroinvertebrate diversity was higher during the wet season at upstream sites, while wide river sites downstream showed a higher diversity during the dry season. Spatial and temporal variations in the macroinvertebrate communities were driven by hydromorphological characteristics and especially by water quality issues reflecting anthropogenic impacts in the river basin. Multivariate analyses using canonical correspondence analysis discriminated between pristine and impacted sites. The caddisfly family Hydropsychidae, the mayfly family Caenidae, and the dobsonfly family Corydalidae were reliable indicators of sites with good ecological status. A relatively small temporal variation was detected in the macroinvertebrate community composition.
