Effects of Environmental variables on rotifer community structure (species number, density, guilds) in inttermittent soda pans of the Carpathian basin 'Adrienn Tóth, 2Katalin Zsuga, 3ZsófIa Horváth, 4Csaba Ferenc Vad, 'Lajos Vörös, 'Emil Boros ' Balaton Limnological Institute, MTA Centre for Ecological Research, Tihany, Hungary 2 Fácán sor 56.

We studied the possible effects of various abiotic and biotic environmental variables (e.g. conductivity, water depth, transparency, concentration of total suspended solids (TSS) and density of microcrustaceans) on rotifer communities (species number, density) and on guilds (functional feeding groups). Spring communities showed a significant negative relationship with TSS and conductivity. Moreover, in the summer communities, the number of rotifer taxa showed a negative relationship with TSS, water depth and density of crustaceans. Regarding density data, spring communities correlated negatively with water depth, TSS and conductivity, while summer communities showed significant negative relationship with conductivity and density of microcrustaceans. Zooplankton communities of intermittent soda pans were mainly dominated by copepods and cladocerans, therefore we also studied their possible effect on the functional feeding groups (guilds) of rotifers. Competition could not been shown between the filter-feeder cladocerans and the filter-feeder micropha- gous guild of rotifers, but the raptorial rotifers showed a negative relationship with the other (raptorial) microcrustacean groups (like Copepoda) and Secchi-transparency. Generally, in intermittent soda pans of the Carpathian Basin, the major driving force in structuring the rotifer communities was not necessarily the salinity in the lower range of the conductivity gradient, but TSS and pre- sence/high abundance of microcrustaceans could be the most important factors Keywords: soda pan, Rotifera, guild, zooplankton,
