Abstract: We investigated the effects of time and depths on phytonbenton community (total phytobenton and diatoms) on

different artificial substrates in Lake Major. Regardless of time, depths and quality of substrates dominance of diatom taxa were observed. Total phytobenton community’s composition collected at the same time was much more similar to one other than community’s composition collected from the same depths or from the same artificial substrates. The changes of cell number was much more complicated: there were not clear dependency observed on time, depths or artificial substrates. Achnanthidium minutissimum dominance was showed during analysis of diatoms. The composition of diatom community was much more time dependent than artificial substrate quality or depth dependent. The number of taxa was higher in most cases (more than 70%) on artificial substrates with rough surface (imitating macrophyte leaves) than on artificial substrates with smooth surface.

Keywords: periphyton community, depth, time, quality of artificial substrate, Lake Major
