The article reports new results on the reconstruction of the noncommercial weakened coppice oak stands in the Left-bank Forest-Steppe zone, Ukraine. For the first time, a technology of reconstruction of coppice stands into the mixed seed natural or planted ones is proposed through regeneration felling with the elements of even gradual, group successive and strip gradual felling with a continuous cutting of 25 m width strips. The use of the technologies that combine regeneration felling, selective sanitary felling and thinning in conjunction with silvicultural activities will allow to form mixed seed natural or planted stands of different ages from noncommercial weakened coppice oak forests and significantly increase their productivity and sustainability.

Abstract Oak (Quercus robur L.) forest stands are among the most common forest formations in the forest-steppe zone of Ukraine. Investigations of the patterns of distribution of trees by diameter and the dynamics of the commodity structure of mature oak stands of coppice origin were carried out based on the forest survey data from 28 temporary sample plots, on the sites designated for the final felling in the Left-Bank Forest Steppe of Ukraine (Sumy, Kharkiv, and Poltava Regions). We distributed trees by diameter classes and technical suitability categories. To establish the commodity structure of the stand, we selected model trees that corresponded to the average size of trees in terms of diameter classes and their qualitative characteristics. Then, we constructed a model tree stem profile using Institute of Forest Ecosystems Research (IFER)’s method of “6 points”. Based on stands’ structure and quality condition as well as on the growth tables, the commodity structure dynamics table for the changes in the commodity structure for the coppice oak stands in the Left-Bank Forest Steppe of Ukraine has been developed. The results of the analysis of wood stock dynamics showed that the maximum average increment of class A and B wood is 90–100 years. Therefore, the age of technical maturity and the associated age for the final felling in commercial oak forests of second site class and above should be assigned to 91–100 years.

The forest site capacity using was quantitatively assessed for the stands of the main forest-forming species of Ukraine, Scots pine and common oak, taking into account natural zones and forest types. The tables of productivity of modal and highly productive pine and oak stands have been developed. It has been found that the stands use an average of 50–75 % of the forest site capacity of lands. The average weighted value of the capacity used by pine forests was 68–76 % in the Polissya zone, 70–78 % and 68–73 % in the Right-bank and Left-bank Forest-Steppe zones respectively, and 54–78 % in the Steppe zone. For oak stands, the value was 71–75 % and 63–71 % for the Right-bank and Left-bank Forest-Steppe zones respectively and 65–75 % for the Steppe zone. The basis for increasing the productivity of forests was confirmed to be the differentiation of forest management systems and individual forestry activities on a zonal and typological basis.

The article presents the results of long-term research of ravine oak forests of the Rostov region.The term ‘bayrack’ (ravine) forest is associated with the growing of forests of this type on the slopes of ravines in the forest-steppe zone. The conducted ecological and floral classification showed a high syntaxonomic diversity of ravine oak forests of the region. Forest communities are represented by 6 associations: Scorzonero ensifoliae–Quercetum Sokolova ex Semenishchenkov 2020; Vicio pisiformis–Quercetum roboris Semenishchenkov 2012; Pyro pyrastri– Quercetum roboris Poluyanov 2012; Chamaecytiso ruthenici–Quercetum roboris Poluyanov 2012; Fritillario ruthenici-Quercetum roboris Onyschenko, Dyakova et Karpenko ex Goncharenko in Goncharenko et al. 2020, Melico pictae-Ulmetum minoris ass. nov. prov. from 2 classes: Carpino–Fagetea, Quercetea pubescentis and 2 unions: Aceri campestris-Quercion roboris and Scutellario altissimae-Quercion roboris. There are 67 rare plant species listed in the Red Books of the Rostov [1], Volgograd [2] and Voronezh [3] regions in the communities of these associations. Oak forests in the south of the European part of Russia significantly increase the biological diversity not only of the Don region, but also of the entire steppe zone of the country.

Aim. Main goals were to study the Bulgarian samples of winter wheat, to identify sources of disease resistance for further breeding work and to develop high-yielding varieties being adapted to the conditions of Forest-steppe. Methods. The experimental part of the work was carried out in 1987-2013 in breeding crop rotations of MIW. 1470 Bulgarian samples were the starting material used. Results. The samples M-61-185, 97 / 58-1, 1769-64, 668-2, 49 / 94-168, 301-44-55, 1990 50, 836 / 87-2 were characterized with stabile high resistance to brown rust in combination with yield on the level of adaptive norm; 3324-1, 1919-50, 77 / 83-71, 2579-30-19, 704 / 90-30, 411 / 92-57, 97 / 58-1, Liliia, Milena – to powdery mildew; 1919-50, Liliia, 836 / 87-2, 6532-5, 49 / 94-168, DM-62-44, 835 / 87-44-38, 97 / 58-1 – to Septoria leaf blotch. Genotypes 759-1, 2579-30-19, 836 / 87-2, DM-62- 44, 1919-50 that combine resistance to group of three diseases with complex of traits: winter-hardiness, large grain, productivity, high quality levels and high-yielding; samples with large grain and high quality – 97 / 58-1, MT-17131-87, 71 / 90-1097, 2514-114 are the most valuable for breeders. Based on 2579–30–19 the new winter wheat variety Hospodynia Myronivska has been developed. Conclusions. Bulgarian samples are valuable as a starting material for winter wheat breeding for disease resistance in Forest-steppe zone of Ukraine. Keywords: winter wheat, Bulgarian sample, disease resistance.

The taxonomic and ecological composition of the autochthonous land mollusc fauna in different parts of the plain Ukraine was analyzed on the basis of the personal data, collection materials of the State Museum of Natural History of the NAS of Ukraine in Lviv as well as numerous literature sources. Excluding representatives of the genus Helicopsis, the taxonomy and species composition of which in the territory of Ukraine still require clarification, and the steppe part of the Crimean peninsula, in four landscape zones of Ukraine, currently, a total of 109 species of land molluscs, which are autochthonous for at least part of the analyzed territory, are registered. The maximum species diversity (103 species and 2 representatives of the genus Helicopsis) is recorded in the zone of deciduous forests, followed by the right-bank part of the forest-steppe zone. The smallest number of the autochthonous species of land molluscs was noted for the right-bank part of the steppe zone. Within the Ukrainian Polesie and the forest-steppe zone of Ukraine, the taxonomic diversity of land molluscs decreases from west to east. The number of the registered autochthonous species decreases, respectively, by 1.5 and 1.7 times, and the generic diversity by 1.3 and 1.5 times. In the steppe zone, the main centre of the species diversity is the Donetsk Upland, located in the east of the country. In taxonomic and ecological composition, land mollusc complexes of the right-bank part of the forest-steppe zone are closer to the zone of deciduous forests, in its left-bank part – to the left-bank steppe. In general, the spatial differentiation of land mollusc fauna in the plain territories of Ukraine is more strongly associated not with the boundaries of landscaped zones, but with the location of these territories with respect to the Dnieper bed and with some uplands, where the species diversity of land molluscs of the zone of deciduous forests and forest-steppe zone (Podolian Upland) and the steppe zone (Donetsk Upland) is concentrated.

In 2017, the 90th anniversary of the senior lecturer of the Department of Geobotany and Plant Ecology of St. Petersburg State University, Honored Ecologist of the Russian Federation, Yu. N. Neshataev (1927–2006) was celebrated. This paper contains a brief review of his researches, as well as the works of his colleagues and students of the Department of Geobotany and Plant Ecology on the study of the unique forests of the site “Forest on the Vorskla river” which is the part of the “Belogorye” reserve (Belgorod Region). For more than 50 years in this place Neshataev carried out researches on the structure, dynamics and functioning of forest communities. New approaches and a multilateral analysis of the structure and dynamics of oak forests in forest-steppe zone were realized in the works of his colleagues and pupils, who continued and developed his ideas.
