Regulation of rotifer community by predation of Cyclops vicinus (Copepoda) in the Římov Reservoir in spring

Popis výsledku v původním jazyce

The structuring role and predation impact of Cyclops vicinus on the rotifer community was studied using in situ enclosure experiments in Římov Reservoir during the spring of 2000. Seasonal changes in abundance and birth rates of the rotifer species Synchaeta lakowitziana, Polyarthra spp., Keratella cochlearis, Kellicottia longispina were related to predation pressure, i.e. selectivity and cropping rates of C. vicinus. All four rotifer species were found to be consumed by C. vicinus whose predation ratesshowed a marked succession through the spring period and corresponded to changes in the relative abundance of the pelagic species. The highest predation rates exhibited by C. vicinus were on Synchaeta lakowitziana and Polyarthra spp., being 11.3 and 6.4ind Cyclops-1 day-1 respectively. The activity of the predator switched among three types of preferred food during the spring period.
