The study of meadow fescue agropopulations was conducted in the agricultural phytocoenoses, established on the leveled coal mining spoils in the forest-steppe zone of the Kuznetsk Basin mining region in Russia. In agrophytocoenoses the fescue is not a dominant species, as in the natural meadows of herbs and fescue, which occupied the area prior to spoiling. However, the presence of the meadow fescue in the newly established plant communities resulted in increasing their biological diversity and improving the forage quality. The species was shown to sustain in agricultural communities on the coal mining spoils for more than 25 years, whereas when sown on the zonal soils it maintains it presence for 4-6 years. The ontogenetic groups of the plant in all communities were found to be dominated by virginile, young and mid-aged generative specimen. By the 25th year of agricultural phytocoenoses development the vitality of the agropopulations decreased on the coal mining spoils, composed of both Quaternary and Permian sediments. The study showed for the first time that meadow fescue is a species with good potential to restore vegetation cover in the areas disturbed by the open coal mining.

The agropopulations of Trifolium hybridum L. were studied in the agricultural phytocenoses established on the levelled coal mining spoils in the Kuzbas mining region (West Siberia, Russia). The clover was found to last in such agrophytocenoses for more than 20 years, whereas in agricultural phytocenoses on the zonal soils it lasted usually for 5-8 years. All studied communities were dominated by virginal and young generative plants. The optimal conditions for the clover growth and development in the disturbed areas were observed in the mixed (legumes and grasses) agrophytocenosis on the hydraulic dump. For the first time T. hybridum was found to be a species perspective for restoring vegetation cover in areas disturbed by open coal mining.

The article presents results of the long-term studies of the structure and production of agrophytocenoses, established on the coal mining dumps in the Kuznetsk basin forest steppe zone. Agrophytocenoses were established on the leveled dumps by seeding grasses and legumes. Another set of control agrophytocenoses was established by the same technic on zonal soil. Seeds were provided by the laboratories of the Central Siberian Botanical Garden SB RAS, Novosibirsk. After 30 yrs of observations it was found that agrophytocenoses on the coal mining dumps did not have initial stage, as well as stage of spontaneous species invasion. Elimination of Trifolium pratense and Arrhenatherum elatius from coal mining dumps phytocenoses took place 3-4 yrs later than from agrophytocenoses on zonal soils. Species did not eliminate totally, but remained in communities with increased or decreased relative abundances. Significant number of species displayed fluctuation, rather than succession in course of 30 yrs development on the coal mining dumps. These phytocenoses It was also found that agrophytocenoses on the coal mining dumps have high long-term production potential.

ABSTRACTThe study the diet of Eneolithic populations is of great interest to archaeologists. However, the studies undertaken in the steppe and forest-steppe zones of Volga region in Russia have left many issues unsolved. Data collected recently through the comprehensive studies of Lebyazhinka VI settlement enable us to change this situation. Of particular importance at this settlement site is good preservation of animal bones, bone fishing tools, and ceramics of the same type with food crusts and connected to a large house pit. For the first time in this geographical area, bones of domestic animals were found in the fill of a dwelling. The aim of this paper is to present the results obtained through comprehensive studies of diet and economy in the Eneolithic based on the materials from Lebyazhinka III and Lebyazhinka VI settlement sites. The main results of the archaeozoological analysis— determinations of species, age and size of the animals—provide the necessary data for studying the diet. We conclude that there are differences between Lebyazhinka III and Lebyazhinka VI settlements. Lebyazhinka III settlement included bones of only wild species, however, Lebyazhinka VI settlement consists of wild and domestic species.

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.

We study the restoration of coal mining dumps through reforestation in the forest-steppe zone of Kuzbass. 3 main forest-forming species (Betula pendula, Pinus sylvestris and Populus tremula) and 11 accompanying tree species were involved in the formation of forest stands. The main forest-forming species was Betula pendula. The amount of renewal was found to be 10.7, 3.1 and 1.0 thousand pcs/ha in sites with favourable, moderate favourable and unfavourable environmental conditions, respectively. The level of natural reforestation on dumps in the southern forest-steppe zone can be described as weak. The renewal of the Acer negundo invasion species was determined by a continuous drift of seeds on the dumps; however, its seedlings and young undergrowth did not reach a generative age.

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.

Goal. To study the spread and severity of slime mold on turfgass in Ukraine. Methods. Field and laboratory methods were used. The research was conducted on two varieties of mixed with different percentage and species composition of cereal grasses. The survey of crops was performed during vegetation in the Polissya, Forest-steppe and Steppe areas. For the identification of pathogen, a selection of plant samples was carried out with further analysis in laboratory conditions. The observations were conducted according to generally accepted methods; spread and severity of disease were determined. Results. The first time in Ukraine revealed damage to the cereal grasses (Physarum cinereum (Batsch) Pers.). Symptoms and morphological characteristics of the pathogen are described. In the Kiev region, in terms of distribution and development, it exceeded other pathogens (30.6—39.0% and 15.4—21.2% correspondingly). In the Kirovograd region, slime mold was observed in 2016 and 2017 at a much lower degree. Its spread was 8.4—10.5% with severity within the range of 3.1—4.5%. In the Zhytomyr region during the period of research symptoms of this disease were not fixed. The most favorable for the development of Physarum cinereum was the growing season of 2017. Conclusions. For the first time in Ukraine, the appearance of disease caused by Physarum cinereum was detected on lawn grasses. The spread of this disease has been noted on both types of grass mixtures. The phytopathological analysis showed that slime mold was the most widespread diseases in the Forest-Steppe zone (Kyiv region), where it dominated in the complex of leaf diseases. In Steppe zone (Kirovograd region) in the period of 2016—2017 it's spread was much lower and in Polissya zone (Zhytomyr region) symptoms of slime mold was not revealed.

This paper presents data on the new location of the moss Ptilium crista-castrensis (Hedw.) De Not, which is listed in the Red Data Book of the Samara Region on the territory of the nature reserve Racheyskie Rocks in the Syzran district. 10 of its coenopopulation loci have been identified and the exact geographic coordinates are given. For the first time the exact coordinates of 11 coenopopulation loci are also named for the holarctic mountain-forest relict fern Polypodium vulgare L., which is also protected at the regional level, both of these species have a mosaic structure of coenopopulations confined to confluent sandstones as a substrate for growth. It has been revealed that the ecological preferences of these species are very close, however, Polypodium vulgare is more shade-tolerant and it can be called a scioheliophyte, in contrast to the heliophyte Ptilium crista-castrensis . The Polypodium requires more humid and shaded conditions for its normal existence. When growing in the forest-steppe zone, where humidity is often a limiting factor, Ptilium crista-castrensis and Polypodium vulgare can form a significant projective cover (more than 30%) only in the northern and northeastern exposures of the substrate, but only with an enhanced light regime in the phytocoenosis at the density of the stand that is not more than 0,3.

First Time

In the forest-steppe zone of Western Siberia, a comparative study of seed productivity, flowering features, fruit and seed morphology, pollen fertilization ability was conducted for the first time in representatives of the Hosta Tratt genus: H. decorata, H. sieboldiana, H. lancifolia, H. albomarginata, H. crispula, H. kikutii, H. montana, H. rectifolia, H. undulata and varieties Golden Tiara, Night before Christmas, and Stiletto. It is noted that the reproductive potential and fertility of pollen in 9 species and 3 varieties of host have intraspecific and varietal specificity and are associated with seasonal weather conditions. The results of free pollination of the host were studied. It was found that fruit formation within a single generative shoot is heterogeneous, with the exception of the species H. decorata. The coefficient of productivity of species is 16—93%, varieties 12.5—36.4%. Morphometric indicators of length of generative shoots, fruits and seeds are presented. It is shown that the fruit is a freely opening loculicidal tricuspid capsule. Seeds are linear to oval in shape. It was revealed that with high viability of pollen grains (46—82.6%) in H. albomarginata, H. rectifolia, H. sieboldiana, the productivity coefficient is 2—3.8 times lower than in H. decorata. The flowers are characterized by geitonogamy with the phenomenon of peterandre, chasmogamous pollination and flowering in acropetal direction. H. decorata has a high adaptive advantage of seed productivity. The studied species and varieties consistently pass all the phenophases of development and are characterized by vitality. The growing season from spring growth to fruiting in Novosibirsk is 98—112 days. The reproductive capabilities of the host during introduction in the forest-steppe zone of Western Siberia are realized partly due to seed reproduction and are distinguished by species and variability.

The work submitted in this paper presents the first checklist of the ant species of the Segura River Basin based on a review of specific literature and biological material collected during field work conducted from 2012 to 2017. Our findings recorded 110 species belonging to 30 genera of ants and twenty two of these species were recorded for the first time in this area. The zoogeographical composition is dominated by the species of the Mediterranean zone (75.2%), followed by the mixed and deciduous forest zone (19.1%). The most important zoogeographic elements are: Iberian (20%), Holomediterranean (17.1%) and West-Mediterranean (13.3%). There are only six cosmopolitan species (5.71%). There is a greater proportion of species from the mixed and deciduous forest zone in the high-mid altitudes in the Segura River Basin, where the climate is cooler, and more humid. The Euro-Caucasian and Euro-West Siberian elements seems to be more associated to the more humid forest, whilst the Euro-Caucasian elements seem to be more associated to ecosystems more similar to the forest-steppe zone. The existence of these different zoogeographic origins in this area is probably linked with: the position between Africa and Europe; the complex geotectonic, paleogeographic, and paleoclimatic history during the last 7 My; the complex geomorphology; and the high climate and habitat diversity. Based on ant studies and other taxa, possible explanations of the zoogeographic origin of these ant chorotypes are proposed.
