Antarctic permafrost soils have not received as much geocryological and biological study has been devoted to the ice sheet, though is more stable older inhabited by microbes. This makes these potentially informative a significant microbial repository than sheets. Due stability of subsurface physicochemical regime, an extreme environment but balanced natural one. Up 104 viable cells/g, whose age presumably corresponds longevity permanently frozen state sediments, isolated from permafrost....
Some organisms in nature have developed the ability to enter a state of suspended metabolism called cryptobiosis when environmental conditions are unfavorable. This state-transition requires execution combination genetic and biochemical pathways that enable organism survive for prolonged periods. Recently, nematode individuals been reanimated from Siberian permafrost after remaining cryptobiosis. Preliminary analysis indicates these nematodes belong genera Panagrolaimus Plectus. Here, we...
Global climate warming disproportionately affects high-latitude and mountainous terrestrial ecosystems. Warming is accompanied by permafrost thaw, shorter winters, earlier snowmelt, more intense soil freeze-thaw cycles, drier summers, longer fire seasons. These environmental changes in turn impact surface water groundwater flow regimes, quality, greenhouse gas emissions, stability, vegetation cover, (micro)biological communities. also facilitates agricultural expansion, urban growth, natural...
Abstract Permafrost and ice are important components of cryogenic planets other bodies, which abundant in the universe. Earth is one many cold type. Earth's permafrost provide an opportunity to test hypotheses that could be applied search for possible ecosystems potential life on extraterrestrial planets. sediments polar alpine regions natural with a unique feature low‐temperature preservation biological material its genetic information. Therefore, studies allow reconstruction events...
54 strains of viable green algae and 26 cyanobacteria were recovered from 128 56 samples collected Siberian Antarctic permafrost, respectively, with ages modern to a few million years old. Although species unicellular belonged Chlorococcales subdominant inside Pedinomonas sp . observed in permafrost. Filamentous Oscillatoriales , Nostocales just found Algal biomass the permanently frozen sediments, expressed as concentration chlorophyll was 0.06–0.46 μg g −1 The number algal cells varied...
Abstract The taxonomic diversity of the algal genus Meyerella is difficult to study because its very simple morphology. Within Chlorella-clade members are distinguished from others by absence pyrenoid. However, it not possible identify them only on basis light microscopy data without involvement molecular genetic analysis methods. At same time, such studies great practical importance, since some have high biotechnological potential, they able accumulate valuable metabolites, including...
Abstract Some organisms in nature have developed the ability to enter a state of suspended metabolism called cryptobiosis 1 when environmental conditions are unfavorable. This state-transition requires execution combination genetic and biochemical pathways 1,2,3 that enable organism survive for prolonged periods. Recently, nematode individuals been reanimated from Siberian permafrost after remaining cryptobiosis. Preliminary analysis indicates these nematodes belong genera Panagrolaimus...
