Nesom, S. novi-belgii (L.) Nesom, S. novae-angliae (L. ) Nesom, S. ciliatum (Ledeb.) G.L.Nesom on the territory of the national ecological network elements - the Dnipro meridian corridor, and the foundations are laid for monitoring of its phytopollution. The morphological, ecological, and chorologic peculiarities of the model taxa are revised, localities were mapped using modern GIS technology, the southern boundary of the secondary area is clarified, which actually coincides with the boundary of the Forest Steppe. Localities marked on the distribution maps are confirmed by the original herbarium collections. The most common species among the identified invasive plants in the Dnipro ecocorridor are: Solidago canadensis, S. gigantea, Symphyotrichum salignum, S. novi-belgii. The latter two are found in the composition of the natural communities of the Phragmito-Magnocaricetea and Molinio-Arrhenateretea classes, which is discovered in the Polissya part of the study area and evidents that they have overcame the coenotic barrier. The main factors limiting the dispersal of the model taxa in the steppe part of the study area are the low humidity and salinity of soil. Prolonged flooding or water-logging, typical for the Dnipro ecocorridor along the banks during spring floods, are the factors limiting their distribution in Polissya and forest-steppe areas. The database is created and filled based on the data from the literature, herbarium and field studies (currently comprises ca. 500 entries). Occurrence of more more than 160 species of adventive plants was established, including several new for the area (Allium tuberosum Rottler ex Spreng., Solidago altissima L., Fallopia baldschuanica (Regel) Holub, Echinops sphaerocephalus L. et al.), that cause phytopollutions on the territory of the Dnipro ecocorridor. The results of the study were presented at two international conferences (II International Scientific and Practical Conference "Actual problems of research and conservation of phyo- and mycobiota", 12-14 November 2013, Minsk (Belarus) and III International round table "Ecology of wetlands and peatlands", February Product Description popup.authors Зав'ялова Людмила Володимирівна Корнієнко Ольга Михайлівна popup.nrat_date 2020-04-02 Close
