| Abstract: | The abundance, density, structure, and dynamics of the populations of 11 rare orchid species are characterized on the basis of observations carried out in the eastern foothills of the Middle Urals from 1991 to 2002. The pattern of changes in the age structure of populations belonging to different ecobiomorphs is revealed. The concept of vegetatively oriented and generatively oriented age spectra of populations is proposed. |
