Ruderal vegetation of Kryvyi Rih. I. Class Artemisietea vulgaris

Self Cite

The article presents results of the study of ruderal vegetation of the class Stellarietea mediae in Kryvyi Rih. The research on syntaxonomy of the class in Ukraine is briefly reviewed. Plant communities of highly competitive annual species of the open temperate humid and dry ecotopes are characterized. The studied vegetation of the class S. mediae is represented by 13 associations, 7 alliances, and 3 orders (15% of the total number of associations of the class in Ukraine). The characteristics of the identified syntaxa are provided. Their features comparing with the communities common for others regions in Ukraine, Russia, and Central Europe were established. It has been found that the alliance Amarantho blitoidis-Echinochloion crus galli is coenotically specific and includes four associations described in Ukraine. Within the examined area, one of these associations, Amarantho retroflexi-Echinochloetum crus galli, was recorded. The results of ordination analysis indicate that ecological differentiation of syntaxa of the studied class in Kryvyi Rih is defined by a set of edaphic factors (soil humidity regime, soil aeration, and nitrogen content). Among the climatic factors, the leading one is the continentality of climate. It has been established that parameters of thermo-and cryoregime do not significantly vary and are not determinant in differentiation of syntaxa of the class. An observed characteristic feature of the class S. mediae is expanding of monodominant communities of Ambrosia artemisiifolia, Atriplex tatarica, Iva xanthiifolia, and Kochia scoparia. It has been found that communities of the class represent initial stages of the overgrowing of ruderal ecotopes in the city. Further research and critical revision of syntaxonomy of the class are needed.

“…At the association level, vegetation diversity in the city of Kyiv represents 30.5% of the total diversity of the class Artemisietea vulgaris in the territory of Ukraine (Dubyna et al, 2019(Dubyna et al, , 2022. Such significant syntaxonomic representation and comparison of this vegetation type with that in other large cities (Kucheryavyi et al, 1991;Yeremenko, 2017) allow us to conclude that within the study area the class Artemisietea vulgaris is characterized by high coenotic diversity. The diversity of man-made habitats as well as regional environmental conditions appeared as the most important factors affecting the variation in this vegetation type.…”

Ruderal vegetation of Kyiv City. II. Class Artemisietea vulgaris

et al. 2023

The article is a continuation of the study on ruderal vegetation of Kyiv City and provides summarized results of syntaxonomic research of the class Artemisietea vulgaris. We identified 14 associations and one derivative community belonging to three orders and four alliances. Using ordination and phytoindication analyses, the synmorphology of the communities, their ecological requirements, and habitat preferences were described. It has been shown that the vegetation of Artemisietea vulgaris is distributed throughout all districts of the city. According to ecological requirements, we found that main environmental gradients that determine the ordination of different types of stands of Artemisietea vulgaris within Kyiv City are thermoregime and light. The diversity of man-made habitats and regional environmental conditions appeared as the most important factors affecting the territorial differentiation of this vegetation type within the city. The contributed data can be used for strategic planning and practical implementation of measures for sustainable urban development and optimization of the urban environment.
