title: [Trait variability in ontogenesis of epiphytic lichen Hypogymnia physodes (L.) Nyl].
abstract: Ontogenesis of the foliose lichen Hypogymniaphysodes has been described on the basis of the material obtained from natural populations. Ontogenetic dynamics (diameter of thallus and the number of lobes) and the features of reproductive structures (the number and diameter of labelloid and galeated sorales) were studied in ecologically different pine forests. We reasonably rejected the use of the variance analysis and nonparametric criteria for the result processing. It was shown that the median dynamics and trait variance may be either similar or different throughout the ontogenesis. The trait variances in ecologically different ecotopes were shown to be different.
