Ecological and biological features of Adonis apennina L. (Ranunculaceae) in the south of the Tomsk region

Three local cenopopulations of Adonis apennina L. were studied in the south of the Tomsk region (environment of the village of Kolarovo, Tomsk region), where the species occurs among meadow-forest herbs. The density of individuals in the studied local areas is low - from 0.7 individuals/m2 to 2.8 individuals/m2. The age composition is characterized by incompleteness: there are no individuals of the pregenerative period or the aging fraction. The reproductive potential has been poorly realized; the seed productivity of an individual shoot is relatively low. In anthropogenically disturbed communities, the productivity of individuals is reduced by more than half. Renewal and maintenance of the number of individuals in natural conditions is carried out exclusively by seed. A comparative analysis of the morphological characteristics of A. apennina in various ecological and cenotic conditions showed that the largest individuals develop in undisturbed communities or those experiencing weak anthropogenic impact. Located in the vicinity. With. Kolarovo has two specially protected natural areas - the landscape natural monument “Kolarovo wetlands” and the botanical natural monument “Slope with relict vegetation near the village. Kolarovo” occupy relatively small areas and are not able to cover all locations of rare species. Based on the research, recommendations were given for the protection of Adonis apennine in the Tomsk region.
