“…Many papers are available on algae from permafrost environments such as tundra (Novakovskaya et al., 2020; Patova & Novakovskaya, 2018; Richter et al., 2018), Antarctica (Komárek et al., 2008; Martins et al., 2020; Mataloni et al., 2000; Pushkareva et al., 2018; Radzi et al., 2019; Van De Vijver et al., 2005, 2010), the Arctic (Barcytė, Pilátová, et al., 2020; Kaštovská et al., 2005; Pushkareva et al., 2016), and the polar and subpolar Urals (Novakovskaya et al., 2023; Patova et al., 2018). Patova and Novakovskaya (2018) determined that in polar extreme soil environments, most species were from the Chlorophyta and Cyanobacteria.…”

“…(2018), the distribution of microalgae and cyanobacteria, especially the distribution of heterocystous cyanobacteria, was determined by soil nitrogen content; the heterocystous cyanobacteria were dominant in nitrogen‐deficient areas and absent or not dominant in nitrogen‐rich soils. The nitrogen content has also determined the species distribution and structure of soils of mountain tundra and sparse forest in the northern Urals (Novakovskaya et al., 2020), where the algal distributions in soils consistently correlated with the region's soil moisture and nitrogen content. Increased phosphate content affects soil algal growth and diversity (Richter et al., 2018; Vijayan & Ray, 2016).…”

Aero‐terrestrial algae are ecologically and economically valuable bioresources contributing to carbon sequestration, sustenance of soil health, and fertility. Compared to aquatic algae, the literature on subaerial algae is minimal, including studies of distinctive habitats such as forest soils, agricultural fields, deserts, polar regions, specific subaerial zones, artificial structures, and tropical soils. The primary goal here was to identify the gaps and scope of research on such algae. Accordingly, the literature was analyzed per sub‐themes, such as the “nature of current research data on terrestrial algae,” “methodological approaches,” “diversity,” “environmental relationships,” “ecological roles,” and “economic significance.” The review showed there is a high diversity of algae in soils, especially members belonging to the Cyanophyta (Cyanobacteria) and Chlorophyta. Algal distributions in terrestrial environments depend on the microhabitat conditions, and many species of soil algae are sensitive to specific soil conditions. The ecological significance of soil algae includes primary production, the release of biochemical stimulants and plant growth promoters into soils, nitrogen fixation, solubilization of minerals, and the enhancement and maintenance of soil fertility. Since aero‐terrestrial habitats are generally stressed environments, algae of such environments can be rich in rare metabolites and natural products. For example, epilithic soil algae use wet adhesive molecules to fix them firmly on the substratum. Exploring the ecological roles and economic utility of soil and other subaerial algae could be helpful for the development of algae‐based industries and for achieving sustainable soil management.

“…Several studies of cyanobacteria in Svalbard [4][5][6][7][8][9], Murmansk Region [10][11][12][13], Karelia Republic [14], Komi Republic, and Yamalo-Nenets Autonomous Okrug [15][16][17][18][19] suggest that polar and boreal cyanobacterial floras probably contain many undiscovered species and genera.…”

The strains of Drouetiella species (Cyanobacteria, Oculatellaceae) from a terrestrial biotope were isolated and characterized using an integrative approach including molecular, morphological, and ecological information. The specimens were collected from the Arctic and Subarctic areas of European Russia. Drouetiella species possess morphological plasticity and can be confused with similar species of Oculatellaceae or Leptolyngbyaceae. The 16S rRNA gene phylogeny supported the strong monophyly of the genus Drouetiella with the separation of four linages corresponding to three known species and one to new taxon. The 16S-23S ITS rRNA sequences of the analyzed Drouetiella strains differ in length and nucleotide composition, which has had an effect on the hypothetical secondary structures of the D1–D1′, Box-B, V2, and V3 helices. As a result of complex study of the genus Drouetiella, a new species—Drouetiella ramosa sp. nov.—is described from the Subarctic of European Russia.

“…The forest and herbaceous ecosystems have different abilities to influence the formation of their internal phytocenotic environment and the composition of the organisms that inhabit them [2][3][4][5]. The various studies have shown the specific features of algal communities in forest, steppe, desert, and other ecosystems [6][7][8][9][10][11]. This is consistent with the definition of the essence of the ecosystem, 1049 (2022) 012072 IOP Publishing doi:10.1088/1755-1315/1049/1/012072 2 where it is represented by a set of interconnected organisms that function in the same territory and interact with the environment in such a way that the flow of energy forms clearly defined biotic structures and the circulation of substances between the living and nonliving components.…”

The results of studies of the environmental regularities of the formation of algal communities in soils of various ecosystems in the south of Ukraine are presented. 26 forest, 11 steppe and 3 saline ecosystems were investigated. The research has established the species richness of algae in each ecosystem and produced a multidimensional ordination of algal communities based on the analysis of the main components to clarify the factors that determine the composition of algal communities. The research has established the species richness of algae in each ecosystem and produced a multidimensional ordination of algal communities based on the analysis of the main components to clarify the factors that determine the composition of algal communities. Predictors determined by edaphic conditions and phytocenotic interactions associated primarily with edificators of ecosystems were used for the analysis. The ecological space of the studied ecosystems was formed by four main factors with eigenvalues greater than one, which explained 81.4% of the total variance. PC1 (34.82% of variance) is associated with the type of ecosystem and such edaphic parameters as pH, the availability of moisture in the habitat, and soil mineralization. PC2 (21.98%) reflects changes in the gradients of trophicity (humus content) and granulometric composition of soils. PC3 and PC4 additionally explain 16.04% and 9.27% of the total data variance, respectively. Their values mainly depend on the mineralization, trophicity, and moisture supply of edaphotopes, which, at the level of the composition of algae, is obviously associated with the heterogeneity of the ecological preferences of the algal species themselves, as well as the variability of ecological niches of ecosystems, due to which there are species more typical for other types of ecosystems in the communities. The use of the factor rotation procedure by the Varimax normalized method made it possible to concretize the taxa most associated with the main components: PC1 indicates the various Cyanobacteria species, PC2 – Chlorophyta, Streptophyta and Eustigmatophyceae, PC3 – Xanthophyceae and Euglenozoa, PC4 – Bacillariophyceae.
