We compared the prokaryotic community composition in the active layer and ancient, 13-19 kyr BP and ~ 40 kyr BP, ice wedge horizons from the same exposure profile of the Mammoth Mountain, using pyrose
Permanently frozen (3-3.5 Ma) alluvial Neogene sediments exposed in the Aldan river valley near the Mammoth Mountain (Eastern Siberia) are unique, ancient and poorly studied permafrost environments. S
Microorganisms in Arctic permafrost retain viability for thousands and millions of years. Particular interest arouses the deposits which not thawed during the Holocene optimum on the North-East Siberi
