The Discovery of Potentially Toxigenic Gloeotrichia CF. natans (Cyanobacteria) in the Continuous Permafrost Zone of Buotama River, Lena Pillars Nature Park in Yakutia, Was Made through the Observation of Epilithic Macrocolonies

Researchers report the first documented mass proliferation of benthic epilithic macrocolonies of potentially toxic cyanobacteria, Gloeotrichia cf. natans, in water bodies within a continuous permafrost zone—the Lena Pillars Nature Park in Yakutia, North-East Russia. This discovery underscores the ecological adaptability of this species under extreme environmental conditions, expanding our understanding of its habitat requirements and chemical composition. Despite its potential toxigenicity, no cyanotoxins (microcystins, cylindrospermopsin, saxitoxins, or anatoxin-a) were detected in the biomass using advanced analytical methods, including liquid chromatography-mass spectrometry and PCR. The study highlights the need for further investigation into benthic cyanobacteria, particularly as climate change alters vegetation periods and permafrost dynamics.
