Distribution of adventive species of the Asteraceae family in the south of Sakhalin
The article is devoted to the analysis of adventive plant species of the Asteraceae family, common in the south of Sakhalin Island. Studies conducted in various areas of the southern part of the island made it possible to identify 50 species of adventitious plants of the Asteraceae family, most of which (41 species) grow in the Yuzh-no-Sakhalinskaya lowland. At the same time, perennial species prevail over juvenile ones, and accidentally introduced species prevail over intentionally introduced species. Of the total composition of the identified advents, 7 species are invasive, and 5 more are weedy. The analysis of adventive species by life forms, in relation to soil moisture, as well as the degree of naturalization and occupied ecotopes, was carried out.
