“…Microbial communities of soils of different natural zones, urbanized biotopes, habitats with extreme conditions have been characterized [160]. An important aspect was the study of the soil microbial communities of Antarctica [161-165]. The dominant fungi in moss-covered Antarctic soil were those from the genera Phoma, Thelebolus, Penicillium, Rhodotorula , in “cobblestone pavement”, Cadophora, Cladosporium, Cladophialophora , in aquatic habitats, Antarctomyces, Hyphozyma, Goffeauzyma, Phoma, Thelebolus, and Geotrichum .…”

ANIMALSThe purpose of a biobank is to accumulate collections that adequately reflect the multidimensional structure of biodiversity (BD), making it possible to explore its various manifestations. An analysis of the scientific status of zoological collections was carried out [1], and it was shown that the collections perform the function of a research sample in BD studies. Their main characteristics are their representativeness, which is further detailed by their informational value, reliability, systemic character, scope, structure, etc.The studies in the "Animals" section are aimed at analyzing key aspects of BD on the basis of an integrated approach combining phylogenomic and phylo-ABSTRACT The "Noah's Ark" project, afoot at M.V. Lomonosov Moscow State University since 2015 and aimed at studying biodiversity, is the largest ongoing Russian project in life sciences. During its implementation, several hundred new species have been described; a comprehensive genetic and biochemical characterization of these species, as well as that of the pre-existing specimens in Moscow University's collections, has been performed. A consolidated IT system intended to house the knowledge generated by the project has been developed. Here, we summarize the investigations around the Moscow University classical biocollections which have taken place within the framework of the project and discuss future promise and the outlook for these collections.

“…In our previous work it was revealed that half or even more of the bacteria cells in Antarctic soil are represented by ultra-small cells [ 9 ]. Moreover, in Antarctic soils, an increased content of such small cells was noted in comparison with the soils of temperate latitudes [ 10 ].…”

The Abundance and Taxonomic Diversity of Filterable Forms of Bacteria during Succession in the Soils of Antarctica (Bunger Hills)

et al. 2021

Previous studies have shown that a significant part of the bacterial communities of Antarctic soils is represented by cells passing through filters with pore sizes of 0.2 µm. These results raised new research questions about the composition and diversity of the filterable forms of bacteria (FFB) in Antarctic soils and their role in the adaptation of bacteria to the extreme living conditions. To answer such questions, we analyzed the succession of bacterial communities during incubation of Antarctic soil samples from the Bunger Hills at increased humidity and positive temperatures (5°C and 20°C). We determined the total number of viable cells by fluorescence microscopy in all samples and assessed the taxonomic diversity of bacteria by next-generation sequencing of the 16S rRNA gene region. Our results have shown that at those checkpoints where the total number of cells reached the maximum, the FFB fraction reached its minimum, and vice versa. We did not observe significant changes in taxonomic diversity in the soil bacterial communities during succession. During our study, we found that the soil bacterial communities as a whole and the FFB fraction consist of almost the same phylogenetic groups. We suppose rapid transition of the cells of the active part of the bacterial population to small dormant forms is one of the survival strategies in extreme conditions and contributes to the stable functioning of microbial communities in Antarctic soils.
