Abstract
The distribution of discrete ontogenetic states of individuals is usually spatially and temporally different within a population. If a sample from the population sample
consists of several subsamples, the comparison of their ontogenetic spectra reveals
heterogeneity of samples, i.e. different subsamples cannot be described by the same
polynomial distribution. Therefore, the comparison of the samples using the aggregate
data is not correct and tends to result in false inferences of biological importance.
The paper proposes three methods for comparison of ontogenetic spectra of heterogeneous samples: a randomized variant of ANOVA, principal components analysis and ordinal regression analysis. The following approaches are exemplified in natural populations of cowberry Vaccinium vitis-idaea L. and epiphytic lichens Hypogymnia physodes (L.) Nyl. and Pseudevernia furfuracea (L.) Zopf.
