During a zooplankton monitoring program in the Rhine catchment (Southern Germany) during the 2006 sampling year, we recorded the mysid Hemimysis anomala in an oligotrophic gravel pit lake. The crustacean and rotifer abundance in the lake was low; max

European whitefish (Coregonus lavaretus) is a dominant zooplanktivorous fish in many praealpine lakes and of great commercial interest. Estimation of prey consumed by European whitefish is essential for the prediction of top down effects in the pelag

The distributions of the coexisting, planktonic, predatory cladocerans Bythotrephes longimanus and Leptodora kindtii were studied at four different stations (Langenargen-Arbon, Fischbach-Uttwil, Bregenzer Bucht and Zeller See) of a great lake, Lake C

High densities of Nannochloropsis, reaching up to 5.7 × 109 cells per litre, were observed in small inland water bodies in Germany. This is one of the few evidences of a Nannochloropsis species in a freshwater habitat. We describe a new species, N.

The formation of chlorophyll a degradation products was measured with natural phyto- plankton from Lake Constance and Daphnia magna and native Daphnia as grazers in grazing experi- ments during spring bloom conditions using high-pressure liquid chrom
