“…Карантинный сорняк, входит в сотню инвазионных видов России (Morozova, 2018), включен в региональные «Черные книги...» (Vinogradova et al, 2010(Vinogradova et al, , 2021Terekhina, 2016). В Новосибирской области пока очень редок, первое местонахождение было обнаружено в Октябрьском р-не г. Новосибирска (Lomonosova, Zykova, 2003), позднее в качестве сорного вид был отмечен в парке Бонсай на территории ЦСБС (Shaulo, Zykova, 2018).…”

Zykova,

Pankova

et al. 2024

New alien species for the Novosibirsk Region are reported: Corydalis solida, Crataegus chlorosarca, Erigeron strigosus,Hemerocallis lilioasphodelus, Lathyrus oleraceus, Polygonum sabulosum, Ranunculus acris (Double Acris Group), Veronica biloba. New localities of rare alien species Astragalus contortuplicatus, Cerinthe minor, Cyclachaena xanthiifolia, Galium aparine, Myosotis stricta, Scleranthus annuus, Symphyotrichum novi-belgii, Symphytum × uplandicum were noted. For each species, its range is given, the distribution in the regions of Siberia is indicated.

“…; A. sativa L.: культивируемое, часто дичает; IIБ, IXБ (¹ , ²); IА: г. Кызыл (Zykova, 2015, Новосибирской области (НО) на конец 2019 г. -305 видов (Zykova, 2019), а с учетом более поздних публикаций -около 330 (Seregin, 2020;Zykova et al, 2022). Рекреационная нагрузка значительно выше в РА и НО, чем и объясняется такая разница в абсолютном числе видов, несмотря на то, что площади регионов вполне сопоставимы.…”

Adventive species in the flora of Tyva

2023

Disturbance of natural ecosystems resulting from the economic development of any region leads to changes in the structure of the vegetation cover. At the beginning of the 21st century, about 70 adventive species were known on the territory of Tyva. To date, the presence of 117 species has been noted in the adventive flora of the region. Most of them are xenophytes, ergasiophytes (departed from culture) – 31 species. According to the degree of naturalization, ephemerophytes predominate – 73 species. The adventive flora of Tuva contains 41 species included in the “List of invasive and potentially invasive species of Siberia” (2014). In comparison with other Siberian regions, there are fewer invasive and potentially invasive species in Tyva, which is associated both with the natural and climatic conditions of the region and with the later economic development of the territory. The most vulnerable to the introduction of alien species were the northern and central regions of the republic, which are characterized by the highest degree of recreational pressure. On the contrary, the outlying territories of the republic, relatively remote from the Central Tuva Basin, are sufficiently protected from the invasion of adventive plants, where, when alien, mainly mesophytic, species are introduced into the flora, the harsh sharply continental climate acts as a limiting factor. The successful introduction of alien species on fallow lands is due to the weakening, up to complete destruction, of natural habitats and plant communities.
