| Popis: | Population ontogenetic studies are an important component of bioecological monitoring. The ontogenetic structure plays a role in determining the current state of natural populations, assessing the rarity status of a species in the region and throughout its range, and predicting the further development of the species. In the Samara region, natural cenopopulations of Anemonoides altaica (C.A. Mey.) Holub were studied on the territory of the Trans-Volga region (Sokol'ya mountains). According to the delta - omega criterion, most of them are mature, some are transitional and young. The revealed features of the ontogenetic structure and the calculated demographic indices of populations indicate the undoubted rarity and vulnerable position of the species in the region. |
