Relationship between the ecological groups of periphytic algae and environmental parameters Ecological groups: low profile guild (LPG), high profile guild (HPG), motile guild (MPG), unicellular and colonial (OCC), filamentous Cyanobacteria (CF) and filamentous Chlorophyta (CHF); Environmental parameters: total phosphorus (TP), nitrates (NO3 −), oxygen saturation (O2) and permanganate index (PI). Weeks of sampling (W1-W8) and substrates (Ceramic, Glass, Yew and Willow) are included as supplementary variables.

Lakatos index – classification of the developed periphyton according to the values obtained for DM, AC and Chl a; sampling weeks are presented in the rows; the obtained results for DM, AC and Chl a types are presented in columns for each tested substrate
