The filtration apparatus of Cladocera: Filter mesh-sizes and their implications on food selectivity
The hypothesis that the species composition of filter-feeding zooplankton is strongly influenced by the amount of suspended bacteria which are available as food only for filter- feeding species with fine meshes is supported.
Filter mesh size and food particle uptake by Daphnia
Simple mechanical sieving provides a sufficient explanation for the mechanism of particle retention of the filtering process in Daphnia.

Variability of filter structures in eight Daphnia species: mesh sizes and filtering areas
The morphology of the filtering apparatus of eight Daphnia species (62 individuals of all size classes) was investigated by scanning electron microscopy. In the majority of animals the intersetular
Natural and Anthropogenic Sulfuric Acidification of Lakes
Since the early 1960s, acid rain has affected surface waters in regions with soils low in carbonates. The acidification of whole lake districts resulted from industrial emissions distributed through
Water quality management of mining lakes: a new field of applied hydrobiology
Underground and opencast mining generated many new lakes, some with dimensions comparable with natural glacier lakes. Research and water quality management on these lakes is multidisciplinary. A part
Selective feeding of four zooplankton species on natural lake phytoplankton
All zooplankters grazed more efficiently on phytoflagellates such as Rhodomonas and Cryptomonas than on coccales such as Chlorella and Scenedesmus, regardless of their relative abundance in the phytoplankton assemblage.

Temperature profiles in summer (February/March 1990) were measured in 24 lakes along a latitudinal transect from central Chile to Patagonia, and on Easter Island, and Lago General Carrera was found to be almost as deep as Lago Nahuel Huapi, which is considered to be the deepest lake in South America.
