The obtained results revealed a considerable species diversity along with low densities of particular zooplankton species, which are characteristic features for slightly humic waters. The most diverse species composition of rotifers was found in the littoral zone of the studied water body. This was probably due to the heterogeneity of the macrophyte-dominated area. Additionally, the presence of fish in the investigated oxbow lake may have been responsible for finding the greatest abundance of Crustacea in the zones dominated by aquatic vegetation.enRotifersCrustaceansPondsSpecies diversityMacrophytesRozdział z książki
