Ecological Systems and Devices Annotation << Back DYNAMICS OF CHANGES IN THE SPECIES COMPOSITION OF COMMUNITIES LAMPENFLORA OF THE VORONTSOVSKAYA CAVE S.Ye. Mazina, A.K. Yuzbekov The dynamics of changes in the composition of phototrophic organisms in a cave excursion Vorontsovskaya (Sochi National Park). The study lasted since the hardware of the cave lighting for nine years. Assessed the rate of growth of communities of phototrophs in various conditions. Revealed that the size of the communities affected by the amount of air fl ow. Species composition of communities of lamp fl ora caves in different years. Characterized substrates, which were developed phototrophs, identifi ed the dominant species. In the initial stages of development of lamp fl ora was dominated by cyanobacteria. Subsequently, in the dominant group consisted of single-celled green algae and mosses. It is established that one of the signifi cant components of fouling communities is protonema mosses. Development of lamp fl ora was accompanied by the destruction of the substrates, calcite and limestone. Keywords: karst caves; lamp fl ora; cyanobacteria; algae; cave ecosystem.
