Description:
The article presents the results of the study of ontogenetic structure and assessment of the state of coenopopulations of Thymus krylovii Byczennikova in steppe plant communities of Minusinsk district of Krasnoyarsk region. It was found that the ratio of individuals of different ontogenetic groups studied coenopopopulations normal, also incomplete. Ontogenetic spectra of the studied right-hand type cenopopulations with a maximum on individuals in the old generative ontogenetic state. According to the "Delta-omega" classification, the studied cenopopulations are aging. The obtained results on the developmental biology, ontogenetic structure and values of the main demographic indicators characterize the coenopopulations of Thymus krylovii Byczennikova as unstable. To evaluate the stability of populations in the study region. It is shown that their optimal state is achieved in these fine-grained steppes. Optimum is achieved mainly due to population characteristics.
