Functional specific of amphibian populations in urbanustic gradient

The article analyzes long-term data on the functional ecology of amphibian’s communities in the gradient of the urbanized environment. Evauated some functional parameters characterizing the stability of the biota at different hierarchical levels of organization (individuals, populations, communities). Estimated preadaptve value of the physiological background of population polymorphism, a number of the trophic links features in urbotsenosis role of reproductive features in the prcesses of morphogenesis diversification, synergistic effects.
