PCA ordination of sampling sites determined by relative community composition. Circled clusters represent sites of similarity based on the sampling season. Three distinct zones were identified (green points – spring season, yellow points – summer season, orange points – autumn season, blue points – winter season). The main species codes are as follows: A-pyr – Achnanthidium pyrenaicum, A-min – Achnanthidium minutissimum var. minutissimum, A-ped – Amphora pediculus, C-ped – Cocconeis pediculus, C-plc – Cocconeis placentula var. euglypta, C-men – Cyclotella meneghiniana, E-sub – Eolimna subminuscula, U-uln – Ulnaria ulna, G-ter – Gomphonema tergestinum, G-oli – Gomphonema olivaceum var. olivaceum, H-mon – Halamphora montana, M-ato – Mayamaea atomus var. atomus, M-var – Melosira varians, N-cap – Navicula capitatoradiata, N-cry – Navicula cryptotenella, N-gre – Navicula gregaria, N-lan – Navicula lanceolata, N-rei – Navicula reichardtiana, N-ven – Navicula veneta, N-aci – Nitzschia acicularis, N-dis – Nitzschia dissipata ssp. dissipata, N-fru – Nitzschia frustulum var. inconspicua, N-pal – Nitzschia palea, N-pus – Nitzschia pusilla, R-uni – Reimeria uniseriata, R-abr – Rhoicosphenia abbreviata, S-han – Stephanodiscus hantzschi, S-min – Surirella minuta, S-bre – Surirella brebissonii var. brebissonii
