Diversity of Cyanobacterium Nostoc and Its Conservancy in Lithuania Nostoc genties melsvabakteri vairov ir jos apsauga Lietuvoje

The article discusses the diversity, distribution and ecology of Nostoc genus in Lithuania. Nine Nostoc species including N. caeruleum, N. carneum, N. commune, N. ellipsosporum, N. linckia, N. pruniforme, N. punctiforme, N. spongiaeforme and N. verrucosum are recorded the most widespread of which are N. commune and N. caeruleum species. Five species were found in NATURA 2000 territories. The widest diversity of species is recorded in aquatic habitats and only two species (N. commune and N. ellipsosporum) are terrestrial. Nostoc species grew in natural and artificial water bodies when water’s pH is 6,0–8,7, temperature - 13,0–27,0 °C and conductivity - 150–390 μS/cm. Article in Lithuanian Straipsnyje aptariama Nostoc genties rū i vairov ir ekologija Lietuvoje. Aptiktos devynios ios genties rū ys: N. caeruleum, N. carneum, N. commune, N. ellipsosporum, N. linckia, N. pruniforme, N. punctiforme, N. spongiaeforme ir N. verrucosum. Pla iai paplitusios yra N. commune ir N. caeruleum rū ys. Penkios rū ys aptiktos NATURA 2000 buvein se. Did iausia rū i vairov nustatyta vandens telkiniuose ir tik dvi rū ys (N. commune ir N. ellipsosporum) – sausumoje. Nostoc rū i individai vyst si natūraliuose ir dirbtiniuose vandens telkiniuose, kuri pH svyravo nuo 6,0 iki 8,7, temperatūra – 13,0–27,0 °C ir savitasis elektrinis laidis – 150–390 μS/cm.
