EPIGENETIC VARIABILITY OF NON-METRIC SIGNS OF ANIMALS FROM POPULATIONS WITH DIFFERENT DEGREES OF ANTHROPOLOGICAL LOADING
The article gives the results of studying of the realized epigenetic variability and stability of homeorhesisin the populations of invertebrate and vertebrate animals under the influence of factors of urbanization. The phenesof four elements of wing sheaths of 100 firebugs (Pyrrhocorisapterus L.) from two local populations of Ishim (the forest park on the suburb of the town and the area with high anthropological loading) are investigated. The variability of 61 phenes of three lower molars and 5 combinations (morphotypes) of grinding surface of the first lower molar of 213 narrow-skulled voles (Microtusgregalis Pall.) in the selections of the forest park and the natural habitat in 16 km away from the town is studied.The level of epigenetic variability in the impact (urban) populations of animals is higher than on the control ones. The phene-markers were identified in the studied populations of firebugs. The significant fenogenetic differentiation of the control and urban populations of narrow-skulled voles, exceeding the level, characteristic for the divisions of one population living at the same distance from each other is shown. The increase of the component of fluctuating asymmetry of bilateral signs under the influence of factors of urbanization is revealed.
