Synanthropic flora of Kuzbass

The article presents the materials of studies of the adventive flora of the Kemerovo region. For the territory of the Kemerovo region, we identified 244 alien species belonging to 162 genera and 50 families. As a result of the increasing process of invasion of new species into the territory of the region, the need for constant monitoring of alien species for the degree of their naturalization, especially in natural cenoses, is urgent. The problem of synanthropic plant species is becoming increasingly important not only for economically developed territories, but also for the relatively preserved mountain regions of Kuzbass. As a result of the studies, it was found that the synanthropic fraction of the Kuzbass flora, consisting of adventive and apophyte species, accounts for about 18% of the total composition of the flora of vascular plants in the Kemerovo region (60 apophyte species, 244 – advent ones). The revealed heterogeneity in the chorological, ecological and biological terms of the species of the adventive fraction makes it possible to find suitable conditions in various types of ecotopes on the territory of the Kemerovo region. This type of work can serve as a basis for developing a strategy for the preservation of natural phytosystems of Kuzbass.

Flora of technologenic landscapes of the taiga zone of the European North-East (Komi Republic)

The results of a long-term studu of the flora of technologenichabitats of the taiga zone of the Komi Republic are summarized. An annotated list of vascular plants is presented, including 406 species from 222 genera and 52 families. For each of them, it is indicated that they belong to a life from, an element of the flora and type of area, an ecologicsl group, zonal and ecotopic affinity. Data on the taxonomic composition of vascular plants, the biomorphrological, geographical, and ecological structures of synanthropic flora, the diversity of synanthropic plant communities, and the stages of vegetation restoration in disturbed areas are presented.

Short Communication: Biodiversity of weeds in Ilmen State Reserve, Russia

Mashkova IV, Krupnova TG, Kostryukova AM, Vlasov NE. 2018. Short Communication: Biodiversity of weeds in Ilmen State Reserve, Russia. Biodiversitas 19: 106-111. Weeds are a synanthropic flora. Human exposure to the natural landscape leads to the spread of synanthropic plant species, so weeds begin to occupy a significant place in the structure of ecosystem biodiversity. The aim of this study was to investigate the weeds biodiversity structure and to assess the extent of invasion of weeds into the territory of the Ilmen State Reserve in South Urals, Russia. This paper presents the results of study of weeds during the vegetation period in 2013–2017. Fifty one species of weeds distributed in four genera and six families were found on the territory of the Southern Forestry of the Ilmen State Reserve. Besides, the differences between species diversity of weeds on three types of roads (gravel, earth and foot) and on two types of forests (birch and pine) were also discovered in this study . The greatest degree of invasion was discovered for foot roads. It was noted that pine forest is the most resistant the invasion of weeds.

Synanthropic plants as indicators of the ecological state of city of Samara

This article focuses on the analysis of synanthropic flora of Samara. It surveys the history of the research of the flora of the city of Samara, and states that it is possible to base the estimation of the ecological condition of the city of Samara on the process and degree of synanthropy. When studying urbanoflorae different authors define the concept of synanthropic flora differently. O.P. Vinkovskaya, E.P. Gnatyuk, and G.S. Antipina, K.V. Kachkin, I.G. Sokolova, T.V. Astakhova, T.A.Terekhina dealt with issues of terminology. The author believes that the synantropic flora consists of adventitious cultivated plants, adventitious ruderal weeds and apofyte types. In the conditions of the increasing anthropogenous change the process of synanthropization of the vegetable cover becomesquite urgent. The article describes the structure of the synanthropic fraction of the urban flora of Samara. The author notes that in the synanthropic fraction the share of monocotyledonous plants has considerably decreased, and that the adventitious species prevail, the flora being made up by forest-steppe boreal, nemoral and multizone plants. In the analysis of the synanthropic component of the flora such indicators as the flora synanthropy index, the adventivity index, index of the apofyteness and the index of cultivation have been calculated. The author comes to the the conclusion that synanthropy causes reduction of the flora variety
