Frozen Zoo: a collection of permafrost samples containing viable protists and their viruses
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 accumulated methane, oxygen isotope ratio or st...
