Decline of clear-water rotifer populations in a reservoir: the role of resource limitation

Popis výsledku v původním jazyce

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 experimentallyas 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.
