Diversity and structure of cenoses of epiphytic algae in open ground and greenhouse
The species composition of epiphytic algae were studied for the first time on the territory of the Botanical Garden-Institute, Ufa Science Centre RAN in open ground and greenhouse. The taxonomic and ecological structure of algae cenoses are studied, species with the highest occurrence: Mychonastes homosphaera, Desmococcus vulgaris, Trentepohlia lagenifera, Chlorella vulgaris, Chlorococcum infusionum were identified. The 34 species and intraspecific taxa of algae with a predominance of Cyanoprokaryota and Chlorophyta were identified on the back of trees in greenhouse, the 24 with a predominance of Chlorophyta - in open ground. The greatest diversity of algae in the greenhouse on the bark of Ficus elastica - (11 species), and the lowest on the Gleditsia triacanthos (4) has been detected. In open ground the greatest diversity of species was found in the study group of deciduous trees - 16 species and intraspecific taxa, the lowest - on shrubs (7). Analysis of algae on ecobiomorphs and morphotypes was conducted. The greatest diversity of species has a stable group of algae, representatives of Ch-, Aer-, C- forms well carrying various adverse conditions.
