Popis: | Long-term data on the morphological anomalies of four anuran species (family Ranidae) and two tailed amphibian species (families Hynobiidae and Salamandridae), inhabiting forest and urbanized areas in the eastern slope of the Middle Urals, have been studied. The morphological deviations of amphibians were investigated in terms of the module principle, which predetermines the similarity of evolutionary transformations in different taxa and limit the number of possible directions of diversification in morphogenesis. The definitive spectra and frequencies of morphological anomalies in juvenile and adult individuals are compared in the urbanization gradient. Original methodological and methodical approaches to using the potential and implemented spectra of deviation are proposed for assessing the role of the ecological component in their formation. The possibility of using deviant forms of variability for assessing the evolutionary and adaptive potentials of the species is discussed. |
