Interactions between Asplanchna and Keratella cochlearis in the Plußsee (north Germany)
Extremely high abundance of Asplanchna priodonta led to a decline in the population of the preferred food species, Keratella cochlearis and subsequently, to the extinction of the predator population. Kellicottia longispina was obviously favoured by the predatory losses of the Keratella. Thus, the interactions between Asplanchna and Keratella influenced the zooplankton community structure.
