Description	The relative importance of and changes in resource limitation of herbivorous rotifers were assessed during the clear-water phase in the Římov Reservoir, Czech Republic, using in situ manipulative experiments. Resource limitation was tested experimentally as the difference in population growth rate among various experimental treatments on four occasions. The reservoir community of rotifers was exposed to three treatments: (i) control, (ii) diluted and (iii) diluted and fertilized. Significant responses to these experimental manipulations were shown by Synchaeta spp., Polyarthra spp. and Keratella cochlearis. Growth rate was usually highest during the spring rotifer maximum and decreased during the clear water phase. The highest intensity of food limitation (expressed as 'Chlorophyll-a' limitation) was found in Synchaeta spp. The relative importance of and changes in resource limitation of herbivorous rotifers were assessed during the clear-water phase in the Římov Reservoir, Czech Republic, using in situ manipulative experiments.

Limitace byla experimentálně testována jako rozdíl v populačním růstu vířníků ve třech pokusných seriích: kontrola, ředěno, ředěno a pohnojeno. Na manipulaci významně zareagovaly druhy Synchaeta spp., Polyarthra spp. a Keratella cochlearis. Potravní limitace byla nejvýznamnější pro Synchaeta spp. K. cochlearis byla naopak málo limitovaná během jarního maxima a významně ve fázi čiré vody. Chlorofyl-a vysvětluje 89, 97 a 92 % potravní limitace pro uvedené druhy. (cs)
