The analysis of metagenomes from four Late Pleistocene permafrost samples allowed us to recognize nearly four hundred genera of protists and fungi, as well as nematodes, in the microeukaryotic assemblage. The sample of the ancient oxbow lake sediment

Permafrost, frozen ground cemented with ice, occupies about a quarter of the Earth’s hard surface and reaches up to 1000 metres depth. Due to constant subzero temperatures, permafrost represents a unique record of past epochs, whenever it comes to

The late Pleistocene Ice Complex (also known as Yedoma) encompasses ice-rich permafrost formed when alluvial and/or aeolian sediments accumulated under cold climatic conditions. Three metagenomes obtained from Yedoma deposits continually frozen for p

Viable eukaryotes of the phylum Amoebozoa from the Arctic permafrost

Autor: Elizaveta Rivkina, Lyubov Shmakova

Publikováno v: Paleontological Journal. 49:572-577

Viable amoeboid protists were isolated from the Arctic Late Pleistocene and Holocene permafrost sediments many of them belong to new species. The diversity of amoebae in the permafrost is rather low in comparison with that of modern tundra soils. The
