Structure of cenopopulations Clausia aprica (Stephan) Korn.-Tr. on the border of the area

The aim of this work was to identify and analyze the ontogenetic and spatial structure of steppe plant Clausia aprica (Stephan) Korn.-Tr. (Brassicaceae) cenopopulations at the border of distribution. The study of cenopopulations and their habitat conditions was conducted at 2006–2021 in Samara, Volg...
