Influence of invertebrate predators (Acariformes) on zooplankton
Feeding of different genus of Acariformes (Piona, Limnesia, Arrhenurus) has been studied in experimental conditions in the meso-euthrophic lake. These species did not consume as large (Sida crystallina, Mesocyclops sp.) as small (Ceriodaphia pulchella) zooplankton. The main consumed species was Polyphemus pediculus. Thereby, the water acarids can control the development of predator of first order and elongate the trophic chain.
