“…Macrophytes and stonewort are also highly structured habitats that increase the surface area. In many lakes, patches of macrophytes often carry the highest number of L. benedeni (Bacescu, 1954;Wonya´r-ovich, 1955;Dediu, 1966;Weish and Tu¨rkay, 1975;Wittmann, 1995;Wittmann et al, 1999). However, Wonya´rovich (1955) mentioned that L. benedeni avoided plants with a biogenous chalk bed.…”

The Ponto-Caspian mysid Limnomysis benedeni was first recorded in Lake Constance in summer 2006, and a stable population developed at the site of discovery. Although this mysid is common in the Rhine and Danube rivers, little is known about its ecology and impact in systems of invasion. We investigated the autecology of L. benedeni in habitatchoice and food experiments. In the habitat-choice experiments, highly structured habitats, i.e., stones covered with zebra mussels (Dreissena polymorpha), macrophytes, and especially stonewort, were strongly preferred. In food experiments, L. benedeni fed mostly on food sources with a small particle size, e.g., biofilm on leaf litter, biodeposited material of zebra mussels, epilithon, and phytoplankton. We also compared the L. benedeni population data from Lake Constance with that from rivers. In Lake Constance, female L. benedeni were nearly 30% larger and carried more than three times more eggs in spring (9.470.6 mm and 28.475.7 eggs) than in summer (6.770.8 mm and 8.772.9 eggs). The mysids present in spring might be the generation that over-wintered; in summer, this generation was probably replaced by a new generation of smaller individuals. The large brood size and the detritivorous feeding strategy might allow L. benedeni to colonize Lake Constance rapidly.

“…benedeni slowly migrated upstream the Danube during the last 50 years (Weish & Türkay, 1975) and was found in the River Main in 1997 (Geissen, 1997) and in the MainDanube Canal, lower River Rhine and the Rhine delta in 1998 (Reinhold & Tittizer, 1998;Kelleher et al, 1999). In addition to moving downstream the River Rhine it also moved upstream the Rhine (from the confluence with the River Main), where it was found near Strasbourg in 1998 (Wittmann & Ariani, 2000).…”
