The fauna of weevils Curculionoidea of Ukraine numbers 1453 species equivalent to 25.3% of European fauna. They belong to 10 families and 364 genera. A total of 51 species are recorded from Ukraine for the first time. Assessment of inventory completeness indicates that 62% of the area of Ukraine are covered by samples. Spatial join analysis has reveals strong collecting biases and shows maximal richness in cells which fall into well-sampled provinces. A total of 22 out of 33 studied model sites are well-sampled (C>0.5). In total, we estimate ca.1470 species of Curculionoidea living in Ukraine. Curculionidae comprise the majority (82%) of the fauna, with 1202 species and 266 genera, and with remarkably high proportion of the three largest subfamilies: Entiminae (26%), Curculioninae (19%), and Ceutorhynchinae (18%). Consolidated data analysis shows highest richness (678–822 spp.) in provinces which fall into the mountain areas. Aggregated species richness for each of five ecoregions uncovers highest values in Pontic steppe (665 species) and East European forest-steppe (593 species). Habitat distribution of weevils is strongly uneven. Most of the richness (565 spp.) is harboured in lowland broadleaf forests. Salt marshes, salt steppes and sands are extreme habitats with low richness but high proportion of habitat specialists. Only 141 dominant species representing 18% of the total fauna but make up to 63% of the total population of weevils in Ukraine. Endemic species comprise a small proportion of the fauna but are remarkably concentrated in the mountains of Crimea (24 species) and the Carpathians (25 species). Along with ‘true’ endemics, 210 species are narrowly-ranged non-endemics and also have higher concentration in Crimea and the Carpathians (105 and 38 spp.). A total of 82 species are qualified as widely-ranged with high concentration in Central European Mixed Forests and East European Forest Steppe (71 spp. on average per province).        The high diversity and evenness of weevil assemblages is shown by species sequence curve analysis in the Crimean Mountains, the Carpathians, steppes and lowland broad leaf forests, which contrasts with assemblages in lowland mixed forests. Shannon-Wiener and Simpson indices both show an extremely broad range of evenness in the Pontic Steppes which have both assemblages with low evenness in Stipa-Festuca-Koeleria steppes and high evenness in Stipa-Bromopsis steppes (H' =1.87–4.22). East European Forest Steppe and Central European Mixed Forests harbour similarly even communities (H' =3.60–4.48 vs. 3.18–4.57). The Crimean Mountains and the Carpathians are defined as a hotspot of biodiversity combining the highest scores of endemics, R1 species, and highest alpha diversity. Host plants are documented for 1259 species. Some 83% of weevils feed on live tissues of angiosperm plants belonging to 64 families. A total of 258 species are confirmed as polyphagous, 8 as monophagous, thus the majority of the rest are more or less narrowly oligophagous. A total of 33.68% of the species are associated with Fabaceae, Asteraceae, and Brassicaceae.

The principles of the habitat concept of biodiversity protection and features of the organization of the European Nature Information System (EUNIS) are outlined. EUNIS covers a wide range of habitats from natural to artificial, from terrestrial to freshwater and marine. It forms a single classification scheme for the entire European space. The factors that influence on bison (Bison bonasus) existence are determined. According to the classification of the WWF, an overview of such ecoregions as Central European mixed forests, East European forest steppe, Pontic steppe, Carpathian montane forests, Crimean Submediterranean forest complex, Pannonian mixed forests. It was investigated that according to the conditions of the Bison bonasus existence among the listed ecoregions, the most favored on the territory of Ukraine are Central Europeanmixedforests. Habitats of Bison bonasus in Europe, which are included in the ecological network Natura 2000, namely Bieszczady, Puszcza Białowieska, Bukovské vrchy, Laborecká vrchovina, Mirosławiec, Jezioro Lubie i Dolina Drawy, Beskyd, Jezioro Wielki Bytyń, Wolin i Uznam, Ostoja Knyszyńska, Ostoja Borecka, Bukovské vrchy, Puszcza nad Gwdą, Jelonka, are established. Of these, 4 are fully and 3 partially located within the ecoregion Central European mixed forests (in full – Puszcza Białowieska, Ostoja Knyszyńska, Ostoja Borecka, Jelonka; partly - Mirosławiec, Jezioro Lubiei Dolina Drawy, Puszcza nad Gwda).It is substantiated that the conservation of bison as a species depends on the possibility of creating large herds existing in the natural environment, which are characterized by maximum genetic diversity. The minimum number of individuals in the bison stage for residence is set. Geosystems which are actual and potential habitats of Bison bonasus within the Ukrainian part of the Central European mixed forestsecoregion and can be added to the European system of protection of Bison bonasus are identified. A map of potential bison habitats within the Ukrainian part of the Central European mixed forests ecoregion is presented.

Trifolium rubens is a Central European forest-steppe plant species reaching its eastern distribution limit in Ukraine and listed in the Red Book of Ukraine (2009).Our study was carried out in 2016–2020 and aimed to analyze the distribution of T. rubens in Ukraine, to identify the composition of phytocoenoses with T. rubens, and to evaluate the current state of its populations in the Zakarpattia region of Ukraine. The distribution of this species was analyzed based on data obtained from the field surveys, literature, online resources, and herbaria. In total, 78 localities of T. rubens were analyzed. Trifolium rubens was found to be distributed in Zakarpattia, Lviv, Ivano-Frankivsk, Ternopil, Rivne, Khmelnytskyi, Chernivtsi, and Vinnytsia regions of Ukraine. Two of these regions (Khmelnytskyi and Chernivtsi) were not mentioned before in the Red Book of Ukraine. The presence of T. rubens in Volyn, Zhytomyr, Cherkasy, and Kyiv regions is doubtful and not confirmed by recent data. Most localities of this species are known from Zakarpattia and Lviv regions.Three new localities were found in the Beregovo district of the Zakarpattia region in the foothills of the Volcanic Carpathians. The floristic compositions of the plant communities and ontogenetic structure of T. rubens populations in Beregovo and Mukachevo districts of the Zakarpattia region were investigated. Investigated populations are isolated with a dispersed disposition of plants on large areas. Trifolium rubens occurs here in meadow-steppe and meadow areas, on hillsides, and also participate in mesoxerophilous secondary (semi-natural) shrub communities in anthropogenically transformed areas. Often such populations are situated along pathways, on forest edges and fallow lands, and associated with ecotones of Trifolio-Geranietea sanguinei class. All studied populations were incomplete with the domination of generative shoots.
