Abstract: Conclusions Traditionaltaxonomyoftendependson single charactersusedfor distin- guishingparticularspecies.ln thisthesis,I haveillustratedapplicationofpoly- phasicapproachesin taxonomyof greenaerophyticalgae.Theseapproachesare basedon thecombinationof variouscharacters(traditionalmorphology,modern molphologicalapproaches,SSU, ITS rDNA andgeneintronsequencing)forthe speciesrecognitionin greenalgae. The morphologicalcharactersaloneareoftennot sufficientfor speciesde- lirnitation,thoughtheycan be usedfor routinespeciesidentificationModern rnorphologicalapproacheslike confocalmicroscopyallow to detectclearmor- phologicaldifferencesarnonginvestigatedcloselyrelatedspecies,evenifat first sightthesemorphologicallyvery uniformalgaehardlydifferatthe morphologi- cal level.
