Аннотация
The results of alien species ecotope distribution analysis in Sverdlovsk oblast are presented. Nine versions of anthropogenic ecotopes pooled into two groups, decorative (residential, park, cemetery) and ruderal-segetal (factory, industrially disturbed, traffic, segetal, coastal water, landfill), are singled out. In the decorative habitats, 243 species occur, and in the ruderal-segetal habitats, there are 286 species. The level of similarity in species composition of decorative and ruderal-segetal habitats (Jaccard coefficient) is 0.54. A common feature of anthropogenic habitats is a very limited number of ecotope specific species—the proportion varies from 1 to 20%. Traffic, residential, and landfill habitats are notable for their very peculiar species composition. At the same time, their plant communities are also characterized by the greatest diversity of alien plants. Only a small proportion of alien species—25 species, or 7%—show a high ecotope activity and have mastered the whole spectrum of man-made habitats. Most alien plants (58%) are found in two to seven habitats and thus are moderately active. About one-third (109, or 32%) of alien species are poorly active and are noted in one particular locality.
