Features of the ontogenetic structure of natural populations Oxytropis hippolyti Boriss. (Fabaceae)

Бесплатный доступ

Monitoring of natural populations of Oxytropis hippolyti Boriss (Fabaceae) was carried out on the Uspensko-Krasnosel'skie peaks (Sergievsky district, Samara region). This is one of the few habitats in the region, but the number of individuals allows us to study the structure and dynamics of populations. The species is protected at the federal and regional levels. Most cenopopulations are incomplete, the basic age spectrum is single-vertex centered with a maximum on mature generative individuals. Ecological and phytocenotic conditions and anthropogenic factors influence the structure and dynamics of populations. Population dynamics of the species is fluctuation. Throughout the entire range, the number of habitats is reduced, in addition, they are subject to significant anthropogenic stress. The condition of the studied populations of O. hippolyti is satisfactory.
