Description
Summary:The article represents the analysis of the ontogenetic composition and demographic parameters of 3 cenopopulations of Myricaria bracteata in the riverbed of the Ursul River (Central Altai). It was found that the ontogenetic structure and density of individuals depend on the degree of formation of the phytocenosis and the influence of abiotic factors (features of the substrate, river bend). The invasive cenopopulation formed in a bend of the river in the absence of a phytocenotic pressure; the young normal cenopopulation formed in the river deflection on the grasscover stony shore, and the invasive-regressive cenopopulation formed on an island washed by the river.
