Particular attention is paid to the consequences of anthropogenic transformation of natural ecosystems and especially to the consequences of the unprecedented anthropogenic load caused by military actions in the conditions of aggression of the Russian Federation. In Pelophylax esculentus, the phagocytic activity of macrophages is significantly lower than in the parental species. This decrease is not directly due to the lower content of pigments in the liver. Indicators of the state of marine mammal populations and the number of cetaceans in the Black Sea are assessed, the historical impact of fishing and the significance of accidental death in fishing gear are shown. Episodic occurrences of arctoboreal and relatively thermophilic forms during cold and warm extremes, respectively, are revealed. Data on the dynamics of ground squirrel ranges in the Late Pleistocene-Holocene time were clarified, the Late Holocene appearance of Spermophilus citellus in this territory and the absence of the extinct S. citelloides were confirmed. The modeling results showed a significant impact of invasive species on local ecosystems. The turtles Trachemys scripta and Mauremys rivulata are spreading in the southern regions of Ukraine, displacing the aboriginal pond turtle (Emys orbicularis). Military operations further complicate the situation, destroying biotopes and creating risks for rare species, in particular Triturus dobrogicus. Zooarchaeological studies of materials from archaeological sites in the Odessa region were conducted. Paleoclimatic reconstructions were made based on the data obtained. Keywords: multivariate analysis, forecasting, modeling, biodiversity, monitoring, ecological factor, animals, population, ecosystem. Product Description popup.authors popup.nrat_date 2025-01-18 Close
