    Abstract

    Analysis of ontogenetic spectra of populations of epiphytic lichen Pseudevernia furfuracea collected in the Republic of Mari El was conducted taking into consideration the heterogeneity of spectra on different trees (different subsamples) within the samples. These results significantly differ from approaches that do not take into account the heterogeneity within the samples. The ontogenetic spectra of the samples are positively skewed with the maximum at ontogenetic state v2. There are very few individuals in ontogenetic states g3, ss or s and their total frequency is 0.4 %. Average population age Δ varies for different samples in the range 0.213–0.300; only three paired comparisons are statistically significant at 1% significance level, whereas six comparisons are significant at 5 % significance level. Recovery index I1 varies in the range 0.418–0.714; only five paired comparisons are significant at 5 % significance level. Using different methods, we estimate the proportion of between-sample variability in the total variability of ontogenetic spectra, which is about 30 %. This means that variability within the sample is the largest proportion of the total variability.
