Hypolithic communities shape soils and organic matter reservoirs in the ice-free landscapes of East Antarctica
Hypolithic horizon: types and transitions Hypolithic horizons most widely occurred in soils of the valley floors and flanks, which were elevated at least ten centimeters above the zone of meltwater streams at the peak of the warm season. We observed two distinct morphotypes of hypolithic horizons (Fig. 2): (1) cyanobacteria-dominated, which comprised biofilm-covered sandy particles several […] More
