LONG-TERM MONITORING OF THE STATE AND ECOLOGICAL FEATURES OF THE ALLIUM SICULUM (UCRIA) LINDL. SUBSP. DIOSCORIDIS (SM.) K.RICHT. POPULATION IN THE KARADAG RESERVE |
V.G. Shatko, Yu.N. Gorbunov, O.I. Korotkov
The results of more than 20 years of monitoring the state of coenopopulation of a rare species of the flora of Crimea, Russia and Eastern Europe – Allium siculum (Ucria) Lindl. subsp. dioscoridis (Sm.) K. Richt. on the territory of the Karadag Reserve. The features of the ecology of its habitat on Karadag compared with those in the Crimean Natural Reserve and the age range of the observed onion coenopulation are established. The analysis of the dynamics of the number of age groups showed that the total number of coenopopulations doubled, the number of age groups fluctuates significantly over the years, which is connected with features of habitat, weather conditions (droughts) and damage by wild boars. Analysis of the state data of the studied cenopopulation of onion shows that it is full-term with a predominance of juvenile individuals in the age spectrum. The population is normal, capable of self-maintenance without germs from outside.
Keywords: Allium siculum (Ucria) Lindl. subsp. dioscoridis (Sm.) K.Richt.; Crimea; Karadag Reserve; ecology of habitat; number; age structure; coenopopulation.
