                                              THE AIMS



•      To  identify epilithic cynobacteria in a running clear water in Slovakia



•      To use cyanobacteria for monitoring clear running waters



                                        MATERIALS & METHODS

•      36 sampling places in Slovakia

•      Scraping from submerged rocky substrata

•      Determination in vivo (Olympus BX 51)

•      Used actual literature for det. of cyanobacteria (Komárek & Anagnostidis 1989, 1998, 2005)

                                            CONCLUSIONS

•      In total, 26 epilithic cyanobacteria

•      The most frequent species (36 sites):

    Chamaesiphon oncobyrsoides

    C. minutus

    Pleurocapsa minor

    Leptolyngbya olivacea

•      The highest species diversity – genus  Chamaesiphon

•      All determined species are kown only from unpolluted, clear streams and rivers

•      Further investigations are necessary
