Zygospore formation in different strains of the Closterium peracerosum-strigosum-littorale complex was examined in this unicellular isogamous charophycean alga to shed light on gametic mating strains in this taxon, which is believed to share a close phylogenetic relationship with land plants. Zygospores typically form as a result of conjugation between(More)
Growth requirements of 10 possibly thermophilic strains of cyanobacteria were compared under a wide spectrum of light and temperature conditions (7–80Wm−2, 12–40°C). The strains were isolated from different localities: six of thermal springs in Slovakia (4 from Piešťany, 2 from Sklené Teplice), one from thermal waters in Rupite, Bulgaria, 2 strains from a(More)
The formation of hormogonia in the nostocalean cyanophytes/cyanobacteria Hapalosiphon fontinalis (C. Agardh) Bornet and Fischerella sp. was studied in natural populations collected from the Klin peatbog, northern Slovakia. Hormogonia were produced terminally in lateral branches of filaments (both species), or also directly on the main branches (Fischerella(More)
