Opis:
This paper presents floristic characterization of xerothermic plant associations and analysis of changes of flora within Broczówka steppe reserve. The floristic research was carried out in 2004-2009. Numerous species that were noted here almost 30 years ago were not found in the present study, the size of other populations decreased. Nevertheless, many plant species occurring in the reserve are rare, endangered or protected. Six major plant associations, impoverished form of two ones and one plant community are distinguished in the whole area of the reserve. Occurrence of two plant associations was not confirmed.

Opis:
The article discusses the issue regarding the reconstruction of social structure of the early Scythian populations from the forest-steppe area of the Dnieper river, in the period between the second half of 6th–4th/3rd century BC, on the basis of funeral materials. As a result of the analysis of the most important elements of burial rites implemented by the discussed population groups, and based on records of ancient authors (The Histories by Herodotus), it has been established that the most valuable sources are the size and complexity of the funerary structure and covering embankment as well as quantitative and qualitative diversity of included inventory. The classification developed on the basis of 198 burials, by means of statistical inference methods, has led to the separation of several classes of graves that can be combined with different social strata. These layers included nomadic higher spheres (leaders of local communities, leaders of “military teams” and tribal aristocracy) and elites of local settled tribes, average members of the population divided into its wealthy representatives and the so-called “simple Scythians” and lower layers of (“the poor”) and people with limited rights (domestic slaves?).

Opis:
Modern technologies make it possible to obtain a lot of diverse information about the soil properties using satellite images, but field studies are also required to create or refine digital soil maps. To create a digital soil map scaled 1:25 000 in 2016, a classical field study was conducted with the laying of soil sections in places with the same coordinates as in the mapping of 1982. It allowed to carry out retrospective monitoring of transformation of morphogenetic and agrochemical properties of soils of the southern forest-steppe of the Republic of Bashkortostan (Russia) for the 34-year period of farm use. Thus, the correction and digitization of the soil map allowed to establish that arable land occupies 69.792 ha (67.9%) in the structure of agricultural land (102 811 ha). The monitoring showed deterioration of the main characteristics of arable soil fertility: the diminishing of humus-accumulative horizons, significant decrease of humus content (p ≤ 0.05), a small but reliable acidification of the medium reaction and reducing labile phosphorus. Losses of organic matter occurred mainly in the most fertile soils; their proportion decreased from 55.9% of the total area of agricultural land to 12.4%.

Opis:
In the light of climate change, it is important to acquire the information on the diversity of flora in order to ensure rational use of steppe rangelands. The present study aimed at diagnosing the botanical and the taxonomic diversity of the arid steppe plant communities in South East of Algeria. A total of 216 phytoecological sampling, were collected in three sites and one sample for each month during 2017 and 2018. The vegetation was analyzed using various species diversity parameters (abundance, species richness, life forms, alpha and beta diversity indices and disturbance index). Results show that 985 plant individuals were classified into 27 species, 27 genera and 14 families, with predominance of Chenopodiaceae and Asteraceae in the arid steppe of El-Haouch, and remarkable dominance of Chamaephytic and Therophytic plants in different phytoecological groups. The state of vegetation degradation in a susceptible environment on Algeria’s rangeland in the South East which is confirmed by the low values of Shannon, Jaccard indices and the values of disturbance index ranged between 50 and 85.71%. The alpha diversity parameters of the different phytoecological groups have low values, which reflect a more fragile homogeneous ecosystem, unfavorable life conditions and the absence of certain species of high pastoral value.

Opis:
The decrease in the agricultural efficiency is associated with the influence of wind erosion, the consequence of which is a decrease in the soil fertility. Significant effects of wind erosion are typical of the arid and semi arid zones with a small amount of precipitation, high air temperature and degree of evaporation, reinforced by strong winds and low differentiation of plant protection. It has been proven that the intensity of the effects of deflation processes depends on the physical and geographical conditions of the distribution of agricultural land, systematic soil protection activities and the availability of vegetation. It has been established that the acceleration of the deflation processes occurs in the territories with increased anthropogenic pressure, which leads to ecological disturbance of the natural balance characterizing territorial ecosystems. In the course of the studies it was found that the natural processes of wind erosion are significantly enhanced by the absence of a scientifically-based and ecological land development system of agriculture, which leads to destruction of the soil cover, reduction of soil fertility, damage to the agricultural crops and, thus, the economic damage. As a result of application of the GIS and ERS technologies, the empirical-statistical model of the possible soil loss due to wind erosion in the territory of the Steppe zone of Ukraine, it has been found that in the course of the deflation processes in the territory taken by naked fallow upon the absence of the conditions for the deflation resistance activities, the value of soil loss at the epicenter of dust storms can reach about 600 t / ha. Studies proved the importance of the deflation resistant action of the vegetation cover, which tends to an increase in the erosion dangerous (favorable) areas of agricultural land by 1.7 times, which reduces the soil loss by 5.62 times. In accordance with the intensity of the effects of the deflation processes and the increase of the soil losses, the contour and land development deflation resistance activities with elements of soil protection agriculture were proposed.

Opis:
The consequences of global climate change are a decrease in precipitation as well as an increase in the length of the period with high temperatures from spring to autumn. The climate change intensified the negative consequences of land reclamation and regulation of rivers by dams in Ukraine in the 20th century. The modern landscape of the Circum-Pontic and Circum-Azov regions in Ukraine has undergone desertification, and a multiple reduction in the freshwater runoff has manifested itself in a violation of the water balance of soils and their salinization. In addition to the climate change and anthropic landscape transformations, most upland areas in southern Ukraine have been converted into farmland, systematically fertilized and treated with pesticides and herbicides. Total plowing of the territory also led to soil erosion and degradation. The global climate change and the impact of human activity have affected the diversity of the steppe fauna as well. The questions of the influence of soil humidity on the diversity of epigeic arthropods were considered on the example of ground beetles (Coleoptera, Carabidae). Soil moisture is one of the key factors that determines their diversity.

The study aimed to determine the long-term changes of the Senecio macrophyllus M.BIEB. population traits: the abundance, reproduction mode, individual fecundity, seed rain and recruitment of new genets in the course of xerothermic grassland overgrowing. The study had also the applied goal: to estimate the chances of "special care" species to survive in the changing environment without management regime for the maintenance of grassland. The model object was the island population of large-leaved ragwort on Biała Góra (the White Mountain) near Tomaszów Lubelski, South-East Poland. To achieve these aims I used the following sets of data: phytosociological relev,s made in plant communities in an interval of 16-18 years; repeated elaboration of the numbers and life-stage structure of the population, both by non-surface and surface method; observation of plants, life cycle in 50 labelled genets; population reproduction and seed rain amounts. The area of an open xerothermic grassland decreased due to the process of overgrowing by bushes which was accompanied by the increasing coverage of forest and meadow herbs as well as monocotyledons, mainly Brachypodium pinnatum and Calamagrostis epigejos. The abundance of the S. macrophyllus population noticable diminished. The flowering mode has been changing during years from an oscillation to a chaotic type which caused the significant decreasing of the individual fecundity, population reproduction and seed rain. In last years it was reflected in the interruption of juveniles’ recruitment.

Recently, the debate on this problem concerns not only archaeological aspects but also specialist analyses, such as archaeozoology or genetics. The interdisciplinary character of the problems explored in this article creates significant research possibilities, especially with regard to the of origins and dating of horse domestication. All of these issues are still open for debate among archaeologists.

In this concept a place or figure can act as a transmitter of national common values or a center around which visions of the past can be formed. Places of memory (lieux de mémoire) are also special kinds of symbols because of their visual character. In the article I try to highlight this based on (mainly) literature of Polish romanticism. A visual character of both figures and its connection with Polish identity and historical discussions make them vital and important motif of Polish past and imaginary.

The purpose of the study was to establish dependence of sunflower productivity on hybrid plasticity under the climatic conditions of the Steppe zone and effectiveness of growth-regulators on the basis of the analysis of differentiation of a vegetation index. The research on the development and productivity of different sunflower hybrids under the natural-climatic conditions of the Steppe zone of Ukraine was conducted in the years of 2019 (medium-wet), 2020 (dry) and 2021 (wet). Spatio-temporal differentiation of the vegetation of sunflower hybrids was established on the basis of calculation of a normalized difference vegetation index (NDVI) using the data of the decoded space images of Sentinel 2. Cartographic and grapho-analytical materials reflecting the reaction of plants to natural-climatic conditions and multifunctional growth-regulators were obtained. The dependence of the reaction of sunflower hybrids to multifunctional growth-regulators on their plasticity in response to the natural-climatic conditions of the Steppe zone was established. There was a weak reaction to application of growth-regulators of the sunflower hybrids Oplot and P64HE133 which are characterized by a high level of plasticity in response to the natural-climatic conditions of the Steppe zone. It was proven that the application of the biological preparation Helafit Combi exceeded the level of agrocenoses productivity in comparison with the chemical preparation ArchitectТМ by 1.1-5.4%. It was established that foliar treatment with growth-regulators led to a decline in water uptake by the sunflower hybrids by 1.2–10.0% in the dry year, by 3.8–8.6% in the medium-wet year and by 3.7%–21.9% in the wet year. There was a significant reduction in the level of water uptake by the hybrid Hector – by 7.7–10.0% and the hybrid 8KH477KL – by 1.2–21.9%. The research results are the basis for forecasting the development of sunflower hybrid crops with further measurement of the crop productivity that allows establishing a probable level of efficiency of sunflower hybrid production by agricultural producers under the climatic conditions of the Steppe zone.

Opis:
The distribution and ecological conditions of the occurrence of Polyporus rhizophilus in Poland are discussed. The species was previously known from only one locality in Dwikozy near Sandomierz. Further localities were found on the roots of Stipa capillata in the Skorocice reserve near Busko Zdrój and at an anthropogenic site among Dactylis glomerata, Poa annua and P. trivialis grasses in an urban park in Końskie. The latter locality is noteworthy as it is situated outside the occurrence range of xerothermic grasslands in the Wyżyna Kielecko-Sandomierska upland. This locality is isolated ecologically from the two remaining Polish localities situated in the xerothermic grasslands.
Polyporus rhizophilus należy do rzadkich grzybów związanych z trawami stepów i kserotermicznych muraw rozwijających się w klimacie kontynentalnym. Na stanowiskach naturalnych notowany bywał głównie na korzeniach wielu gatunków traw, jednak najczęściej z rodzaju Stipa. W Polsce znany był do tej pory z jednego stanowiska w Dwikozach koło Sandomierza. Kolejne jego stanowiska zostały odszukane w rezerwacie Skorocice koło Buska Zdroju, na korzeniach Stipa capillata oraz w Końskich, w parku miejskim, na siedlisku antropogenicznym, wśród traw Dactylis glomerata, Poa annua i P. trivialis. Interesującym jest stanowisko w Końskich, leżące poza północną granicą zasięgu Polyporus rhizophilus, poza obszarem występowania muraw kserotermicznych na Wyżynie Kielecko-Sandomierskiej. Występowanie tego gatunku grzyba na izolowanym stanowisku być może należy wiązać z globalnym zjawiskiem ocieplenia klimatu. Na ten problem zwracał już uwagę Kreisel (2006), który zalicza m.in. Polyporus rhizophilus do grupy grzybów ciepłolubnych rozszerzających swój areał na północ w kontekście aktualnych zmian klimatycznych.
