| Abstract [eng] |
The aim of the study was to investigate the morphology, ecology and phylogeny of cyanobacteria belonging to genera Nostoc and Desmonostoc in Lithuania. The detailed research of freshwater and terrestrial Nostoc and Desmonostoc species provided new data on taxonomy, biology and ecology of these cyanobacteria and the overall diversity of algae in Lithuania. 20 Nostoc species and two intraspecific taxa, and 18 taxa to the Nostoc genus level were identified. Twelve Nostoc species and intraspecific taxa, Desmonostoc genus including two taxa were recorded for the first time in Lithuania. A check list was compiled of all identified species with original morphological and ecological data as well as pictures. An applied research by different types of Nostoc and Desmonostoc species samples was valuable in morphological analysis – suitability for identification and stability of diagnostic morphological features in species was identified. The highest diversity of Nostoc and Desmonostoc species were recorded in lentic ecosystems and 14 species were found in terrestrial habitats. A wide genetic and morphological diversity of Nostoc and Desmonostoc species was identified while performing fingerprint TGGE and morphological analyses of cyanobacterial natural populations. The morphological and phylogenetic analyses of Nostoc and Desmonostoc strains showed morphological and phylogenetic heterogenity of Nostoc species and differences of the same types between Desmonostoc and Nostoc species. |
