    Geobotanical study of ruderal vegetation in the geoecological monitoring program of roadside ecosystems of the Cherkasy oblast
    (Видавництво Чернівецького університету, 2023-10-29) Sergiy SONKO; Tetiana MAMCHUR; Iryna KRAVTSOVA; Ivan MOSTOVYAK; Yurii KISELOV
    The article is devoted to the dynamics of the spread of ruderal vegetation in phytocenoses of the roadside ecosystems of the Cherkasy oblast. Due to the high plowed area of the region, roadside field protection strips, in which, in fact, phytocenoses with the participation of ruderal plants are formed, are mostly very narrow (on average 10–15 m). Such ecotopic limitation creates extremely harsh ecological conditions in which only competitive (and sometimes aggressive) species survive. Unlike most works devoted to the formation of the phytodiversity in roadside phytocenoses, the authors follow the concept of infraecosystems presented in previous publications. The main distinguishing feature of this concept is the assumption of different states of formation of natural ecosystems on roadsides. In particular, by comparing the available phytodiversity in roadside phytocenoses with the «National Catalog of Biotopes», the degree of completeness of ecosystem formation at 19 study sites was assessed. Highways in the meridional (11 polygons) and latitudinal (8 polygons) directions were investigated within the Cherkasy oblast. Among the investigated phytocenoses at 19 polygons, only 4 phytocenoses, which spatially coincide with gas stations (Esco gas station, exit from the city of Uman, SOCAR gas station, near the village of Sharyn), or with relatively isolated settlements at the exits to the main route (Bilashki village, Rotmistrivka village). Invasive species (more than 10), which take an active part in the formation of the phytodiversity, were also found at all landfills. According to our estimates, the general trend of the formation of roadside ecosystems falls under the principle of Le Chatelier-Brown compensation, according to which the biosphere confirms its extraordinary ability to support life every time. After all, it can reduce, eliminate, and finally nullify any destructive (man-made) impact, filling existing and creating new ecological niches. Such an understanding of the geobotanical component in monitoring studies will help in the future to more correctly determine the role of man and the biosphere in the formation of anthropogenic landscapes, one of the more dynamic varieties of which are roadside landscapes.

    Geographical Foundations of the Sustainable Development Concept: the Paradigmatic Level
    (IOP Conf. Series: Earth and Environmental Science, 2023-05-23) Sergiy SONKO; Shiyan D.V; Maksymenko N.V.; Vasylenko O.V; Ogilko S.P.
    A constructive solution to the global environmental problem is possible within the framework of the information-space-time paradigm, the main of which is a constant (in terms of the main laws of conservation) amount of information, space and time, and thus deriving equivalent interchangeable units of their measurement. The methodological uncertainty of the very idea of sustainable development prompts the interpretation of this idea precisely taking into account the geographical picture of the world in the context of the informational-spatial-time paradigm.

    Urboecosystem as a human ecosystem
    (London, International Science Group., 2023-07-28) Sergiy SONKO
    The uncertainty, contradiction and significant contrast of theoretical approaches to the selection of the "human ecosystem" logically closes precisely on the problem of urbanization and urban settlements. It is interesting that there are very frequent diametrically opposed statements not only by different authors, but also by the same author regarding the possibility of including cities in the rank of natural ecosystems [1]. Optimism in the views on the development of cities of the world-famous architect K. Doxiadis (who believed that the surface of the globe will eventually be covered by the territory of a "continuous city") has already been replaced by a more sober view of the American architect-deurbanist W. L. Wright, who says: " Just as a tumor becomes malignant, the city, as a deadly entity, has become a threat to the future of humanity. Our great cities, these vampires, must die." Despite this, anthropocentrism in solving the problems of urbanization not only did not cease to exist, but also intensified. Therefore, if the problems of modern urbanization can be solved, then only by taking maximum account of the actual ecological properties of cities.
