Abstract

The Gießgang at Greifenstein is a 42 km long artificial irrigation system in the northern Danube backwaters near the reservoir of the Greifenstein hydropower station (River Danube, Lower Austria). Benthic invertebrates were sampled monthly from July 1992 to June 1993 in three different habitats: lotic sections with gravely substratum; mud and silt in the stagnant parts of old river-branches; aquatic vegetation as well as bank vegetation in lotic and lentic sections. 23 species of Odonata were asigned to four different assemblages. Despite the artificial conditions, after a period of 8 years adaptation, most of the Ephemeroptera now consist of naturally expected species, including some rare and endangered taxa.
