Gloeotrichia cf. natans (Cyanobacteria) in the Continuous Permafrost Zone of Buotama River, Lena Pillars Nature Park, in Yakutia (Russia)

As global climate change continues and the vegetation period lengthens, importance of research into cyanobacterial recruitment biomass associated toxin risks is growing. While most studies focus on planktonic cyanobacteria causing blooms, benthic have been less explored. This study reports for first time mass proliferation epilithic macrocolonies cyanobacteria, Gloeotrichia cf. natans, in water bodies located a region with continuous permafrost Yakutia, North-East Russia. The characterizes environmental conditions its habitat, including chemical composition water, which expands our understanding this species’ ecology. Cyanotoxins (microcystins, cylindrospermopsin, saxitoxins, anatoxin-a) were not detected natans using liquid chromatography–mass spectrometry PCR methods.
