Studied the content the content of phenolic compounds (flavonols, flavans (catechins), tannins), polysaccharides (pectins, protopectins), tetraterpenes (carotenoids) and antioxidant activity of Cichorium intubus L., Taraxacum officinale Wigg., Arnica iljinii (Maguire) Iljin., Echinops sphaerocephalus L. cultivated in conditions of Western Siberia. A significant part of the biologically active substances are tannins (up 28.25%) and protopectins (up 11.11%). The content of flavonoids in the studied samples of C. intybus plants corresponds to the indicators of chicory grass for other regions of the Russian Federation, including the regions of its industrial cultivation. The flowers and leaves of the studied samples of T. officinale are characterized by approximately the same content of flavonols (1.02–1.43%), pectins (0.80–1.08%) and protopectins (7.94–8.87%). The leaves and flowers of A. iljinii are distinguished by a rather high content of flavonols (up to 4.23%) and tannins (up to 28.25%). In terms of the content of tannins (8.34%), catechins (36.3 mg/%), protopectins (10.06%) and carotenoids (64.60 mg/%), the leaves of E. sphaerocephalus are significantly superior to the flowers. Flavonols are present in equal proportions in leaves (0.68%) and flowers (0.64%). Indicators of the total content of phenolic antioxidants in the leaves and flowers of C. intubus, T. officinale, A. iljinii, E. sphaerocephalus do not differ significantly.

The paper considers the features of the phenotypic structure formation of blue rock pigeons populations on the basis of plumage color on territories with varying degrees of urbanization. The distribution of morphotypes may depend on the number of pigeons in flocks (the density of micropopulation groups), which is determined by migration processes associated with the transformation of the habitat, changes in foraging and other factors. An important role in the phenotypic structure formation of the pigeon population is the development of adaptations to living conditions in the city. The most anthropotolerant and, accordingly, adapted to the conditions of urbanization, are the most numerous morphotypes - black and grey, which have developed various adaptation strategies in the process of co-evolution. Representatives of these morphotypes predominantly constitute the sedentary part of pigeon populations in urban areas. Migrants, among whom, apparently, there is a large proportion of aberrant morphotypes or hybrid forms, demonstrate less adaptability to anthropogenic impact and to the conditions of urbanization. The existence of stable polymorphic populations of blue rock pigeons in the urban environment indicates the development of multidirectional behavioral strategies that make it possible to fully use the features of urban landscapes and adapt to humans and numerous anthropogenic disturbance factors. One of the directions of the adaptive population strategy of blue rock pigeons is the development of moderate anthropotolerance, which is possessed by representatives of the most common black-striped phenotype.
