Abstract

Peculiarities of soil ecosystems (algae, microbiocenosis, agrochemical and agrophysical characteristics) of the Uholsko-Shirokoluzhanskyi beech relict forests of the Carpathian Biosphere Reserve, as well as artificial European beech (Fagus sylvatica L.) plantations located on the botanical and geographical plots "Ukrainian Carpathians" of the M.M. Gryshko National Botanical Garden of NAS of Ukraine. Soil samples were collected from May to September during 2020–2021. The species composition of soil microalgae, the number of ecological and trophic groups of microorganisms, agrophysical and agrochemical characteristics of soils were analyzed. The predominance of green algae with a significant diversity of green flagellates and the complete absence of cyanobacteria are typical features of forest soils. The small number of detected species (12 in beech relict forests and 15 in artificial beech plantations) indicates shaded forest ecosystems which are typical for beech forests. Despite common features, the species composition of soil algae of both phytocenoses is quite different. The soils under the beech relict forests are characterized by a significant predominance of green algae, among which essential number of Trebouxiophyceae representatives with aerophytic ecology were found. It indicates the mountainous nature of the soil algal flora. Soils under artificial beech plantations are characterized by a richer species diversity and predominance of Chlorophyceae representatives, which is typical for lowland forests. A characteristic feature of protected and artificially created beech forests was the relative high number of micromycetes. Correlation analysis of research results showed a positive relationship between algal diversity and the abundance of two eco-trophic groups of microorganisms: actinomycetes and ammonifiers. In addition, the growth of algal diversity was positively correlated with the content of Ca and Mg, and negatively with the content of P.
