Abstract: | Salar de Uyuni (SdU) is the biggest athalosaline environment on Earth, holding a high percentage of the known world Li reserves. Due to its hypersalinity, temperature and humidity fluctuations, high exposure to UV radiation, and its elevated concentration of chaotropic agents like MgCl2, LiCl and NaBr, SdU is considered a polyextreme environment. Here, we report the prokaryotic abundance and diversity of 46 samples obtained in different seasons and geographical areas. The identified bacterial community was found to be more heterogeneous than the archaeal community, with both communities varying geographically. A seasonal difference has been detected for archaea. Salinibacter, Halonotius and Halorubrum were the most abundant genera in Salar de Uyuni. Different unclassified archaea were also detected. In addition, the diversity of two subsurface samples obtained at 20 and 80 m depth was evaluated and compared with the surface data, generating an evolutionary record of a multilayer hypersaline ecosystem. |
