| Abstract: | Hoito Gol hot spring of weakly mineralized warm (36–29°C) neutral and partly alkaline nitrogen-carbon dioxide waters belongs to the hydrogeological structure of the actively water-flooded fault marked by the Sentsy River at the southwestern termination of the Baikal rift system. The spatiotemporal evolution of the major parameters of the underground aqueous ecosystem of this spring is controlled mainly by geological and geodynamic factors, whereas the parameters of the surface system are determined mostly by bacterial factors. Variations in these factors are correlated with changes in the composition, structure, and spatial distribution of the bacterial communities. |
