Seasonal changes in the abundance of the herbivorous moth larvae Acentria ephemere/la on submersed macrophytes in Lake Constance were studied between 1998 and 2000. Acentria were found feeding on many pondweeds (Potamogeton lucens, P. pectinatus, P. perfoliatus), Ceratophyllum demersum and Myriophyllum spicatum, but not on Chara spp., Najas marina ssp.(More)
Epiphytes cause a strong light attenuation for submersed macrophytes. Various abiotic and biotic factors determine epiphyte density, among them nutrients, water clarity and possibly allelopathy. We compared epiphyte biomass on the major occurring macrophytes, among them allelopathically active species in four shallow eutrophic lakes in Upper Swabia(More)
