Population dynamics of two endemic species in Aksu-Zhabagly State Nature Reserve

Abstract

The structure of Allium pskemense and A. karataviense coenopopulations from the Aksu-Zhabagly State Nature Reserve was described. It was established that the ontogenetic spectrum of coenopopulations is left-sided with a maximum on immature individuals. This is due to good seed reproduction, rapid rates of development at the end of ontogenesis. It was shown that over a 10-year period, there is a gradual aging of the coenopopulation, which is reflected in the shift of the peaks in the spectrum to the young generative (A. pskemense) and virginal (A. karataviense) groups. It was concluded that the sustainable development of coenopopulations will be in the case of a decrease in the number of the phytophages and successful regeneration by seed, which leads to a regular turnover of generations.
