The unusual dominance of the yeast genus glaciozyma in the deeper layer in an antarctic permafrost core (Adélie Cove, Northern Victoria Land) Is driven by elemental composition
Rock glaciers are relatively common in Antarctic permafrost areas and could be considered postglacial cryogenic landforms. Although the extensive presence of rock glaciers, their chemical–physical and biotic composition remain scarce. Chemical–physical parameters and fungal community (by sequencing...
