Abstract

The ontogenetic population structure of species forming the undergrowth layer in oak woods of the Novgorod-Seversky Polesye: Corylus avellana, Frangula alnus, Sorbus aucuparia, Euonymus verrucosa, Padus avium is considered. For populations of these species the completeness and symmetry of the ontogenetic ranges, and belonging to invasion, normal and regressive categories are defined.
