Diversity of fishpond zooplankton in Javořice highlands region
 IŠTOK, Tomáš
It studied the species composition of pond zooplankton selected pond in Javořická highlands, near Nová Bystřice and Slavonice. Sampling was pelagial and at selected locations and littoral ponds. When selecting sites sampled, the emphasis was on the selection of sites with historical, expected or actual occurrence Heterocope saliens that occurs on sites with ponds and bogs around the aquatic environment with lower pH. These sites are usually extensively farmed. Found 69 species (24 Cladocera, 15 Copepoda, 30 Rotatoria).
