Abstract The information on the spontaneous spread (1152 localities) of the invasive species Echinocystis lobata is summarized. It was found that this alien species is timed to coastal water biotopes, floodplain meadows, mesophytic forests, wetlands, as well as disturbed ecotopes. The syntaxonomic scheme of vegetation with the participation of E. lobata includes 13 classes, 7 orders, 8 alliances, and 8 associations. It is predicted that under the conditions of a temperature increase of 3 °C, there will likely be changes in the carbonate content (Ca), water regime (Hd) of the soil, thermal regime (Tm), and climate humidity (Om), which will cause a reduction in the secondary range of the species in Ukraine, and the changed acid regime of the soil will cause (Rc) its disappearance in some localities. The obtained data can be used to carry out preventive measures regarding the emergence and further distribution of E. lobata in new habitats with different degrees of anthropogenic transformation.
摘要 总结了入侵物种 Echinocystis lobata 自发传播（1152 个地点）的信息。研究发现，这种外来物种适时出现在沿海水域生物群落、洪泛平原草甸、中生代森林、湿地以及受干扰的生态群落中。有 E. lobata 参与的植被分类法包括 13 个类、7 个目、8 个联盟和 8 个协会。据预测，在温度升高 3 °C 的条件下，土壤中的碳酸盐含量（Ca）、水分含量（Hd）、热量含量（Tm）和气候湿度（Om）可能会发生变化，这将导致该物种在乌克兰的次生分布范围缩小，而土壤酸度的变化将导致（Rc）该物种在某些地区消失。所获得的数据可用于采取预防措施，防止 E. lobata 在人为改造程度不同的新栖息地出现和进一步分布。

Abstract The only location for the protection of Arowana golden-red in its natural habitat is in east-central Sumatra. Currently, the area is being invaded by oil palm plantations. This research identified the present conditions in that conservation area, specifically focusing on land-use situation and aquatic organism distribution and diversity. We designated four sampling sites according to the stratification of river flows that pass through the Arowana golden-red conservation area and present land use. The research showed that oil palm plantation was the largest land use in the Arowana golden-red conservation area covering 61.2% (2,310.84 ha). The swamp forest which is the habitat of Arowana golden-red only remained at 6.99% (263.98 ha). In the study area, aquatic organisms were identified as 47 species with a total of 424 individuals: 7 genera of Benthos, 11 species of Planktonic algae, and 29 species of Fish. The diversity index was in the range of 0.46–2.45. The diversity of aquatic organisms was found to be comparable to or higher than other areas in Malaysia and Indonesia such as Aceh province and Kalimantan. However, only 31 individuals of Arowana golden-red were found in the swamp forest in Middle Mahato. This site should be a priority area to save the Arowana golden-red.

Abstract The development of each spatial unit is determined by the capital, whether natural or socioeconomic, which it possesses. Natural capital is determined by the properties of individual natural components of the landscape, both abiotic and biotic sources. Socioeconomic capital is linked to a socioeconomic activities in the landscape. Capital creates certain prerequisites for the development of individual socioeconomic activities. Society does not always optimally use the offered potential, which is connected with the manifestation of various environmental problems. The paper focuses on the presentation of the methodical procedure of natural capital evaluation on the example of the village of Važec. The methodological procedure is based on an integrated approach to the landscape. It focuses on the assessment of both natural capital and limiting factors resulting from the development of socioeconomic activities, namely: – positive arising from the needs of nature and landscape protection, as well as from the protection of natural resources, – negative (stress factors) linked to the contamination of environmental components, which in retrospect in relation to socioeconomic activities act as hygienic limits.

Abstract Parthenocissus inserta (A. Kern.) Fritsch. adapts to living in the forests of Ukraine. The influence of P. inserta on native species and its consortial ties with representatives of the secondary ranges biota, in particular birds, has not been studied. The purpose of this study is to make an inventory of the consorts’ ornithocomplexes of P. inserta, to give a comparative analysis of topic and trophic consorts as a result of an introduced species’ participation in the transformation of habitat’s conditions. The material was collected from 2019 to 2022 in forest parks and urban green spaces of the Kyiv city. The bird distribution was determined by the standard method of counting birds at points. Exactly 12.2 ha of P. inserta plantations were surveyed. Trophic consortium relationships of P. inserta with 32 bird species and topic ones with six bird species were revealed. The species composition of consorts was higher in forest fragments than in urban plantations (26 and 21 species, respectively). In the ornithocomplexes of P. inserta consorts in forest biotopes, there was a smaller pressure of dominant species and a more evenly ranked distribution of species by abundance than in urbanized ones. The similarity of the consort’s species composition in urbanized and natural biotopes according to the Sorensen index was 0.64, in consorts 1 and 2 of the consortium concentres was 0.32, and in topic and trophic consorts was 0.27. According to the status of stay in the region, trophic consorts of P. inserta were mainly resident birds – 20 species (62.50%), wintering birds – six species (18.75%), and birds migrating through the region – six species of birds (18.75%). Among the topic consorts, there were four species of sedentary species and two species arriving for nesting. Principal component analysis revealed the largest positive relationship between P. inserta planting area and the number of consort bird species nesting (0.999) and feeding (0.889) on girlish vine plants. We predict that in the future, P. inserta will be more strongly woven into the matter cycle of the secondary range ecosystems. The study of consortial relationships between invasive plants and birds, taking into account the knowledge of the ecological characteristics of consort birds, will make it possible to more effectively prevent the spread of plants into natural biotopes.

Abstract This work is part of the exsitu conservation of Ruta montana (L.) L., a spontaneous Rutaceae, known for its many therapeutic properties. The aim is to study, under controlled conditions, the effects of daylight and darkness, temperature, salt, and water stress on the germination of its seeds. Salt stress was induced by different molar concentrations of NaCl (0–200 mM), and water stress was simulated using different concentrations of polyethylene glycol (PEG6000) corresponding to different water potentials (0-1.2 MPa). The results obtained showed that R. montana seeds were viable and could germinate both in daylight and in continuous darkness. Germination was possible at temperatures between 10 and 30 °C, with the maximum final germination percentage (FGP = 81.66%) recorded at 20 °C. At this optimum temperature, FGP decreased significantly when the seeds were placed under salt and water stress (p< 0.01).This decrease became more and more significant when the osmotic pressure induced by NaCl increased and when the water potential induced by PEG6000 in the medium decreased. The depressive effect of salt and water stress on FGP was verified by a linear regression analysis, which showed high values of the coefficient of determination (R2):0.934 for water stress and 0.890 for salt stress. This effect on the velocity coefficient and latency time was more moderate or lower. The thresholds of tolerance to salinity and water deficit found were 150 mM and −1 MPa, respectively, for which the lowest FGP values were recorded with 16.25% for water stress and 11.10% for salt stress.

Abstract We carried out studies of the translocation of heavy metals in the soils of Kryvyi Rih. The peculiarities of the accumulation of heavy metals in the assimilation apparatus of seven poplar cultivars were clarified. The maximum rates of translocation of heavy metals were detected at the monitoring site of the industrial site of Northern Iron Ore Dressing Combine (henceforth referred to as Pivnichnyi HZK or PivnHZK). In the leaves of poplars “Lvivska,” “Hradizhzka,” and “I-45/51,” cadmium, one of the highly toxic elements, accumulates 25–30 times more than in the leaves of control plants. High rates of accumulation of heavy metals lead to a violation of the functioning of the plant organism at the physiological and biochemical levels, as evidenced by changes in the content of chlorophyll a and b. The amount of the main pigments of photosynthesis in the leaves of poplar cultivars under conditions of environmental pollution with heavy metals is lower than in the control, which indicates the inclusion of plant signaling mechanisms. At the same time, the amount of carotenoids in the organs of assimilation of poplars growing on the industrial sites of Northern and Central Iron Ore Dressing Combines (henceforth referred to as Central HZK or CHZK) increases and indicates the realization of their protective functions. The investigated cultivars can be divided into two groups according to the intensity of changes in pigment content. The first group (with a decrease in chlorophylls up to 2 times and an increase in the amount of carotenoids up to 2.5 times) includes “I-45/51,” “Lvivska,” and “Hradizhzka,” and the second group (with a decrease in chlorophylls by more than 2 times and an increase in the amount of carotenoids by more than 2.5 times) includes “Keliberdynska,” “Robusta,” “Sacrau-59,” and “Tronco.” This fact indicates better adaptation and greater resistance of cultivars of the first group to the action of heavy metals.

Abstract The determination of potentially toxic element concentrations in fish is an important topic from the point of view of both nature conservation and human consumption. The aim of this study was to assess the concentrations of S, K, Ca, Cr, Mn, Fe, Zn, Rb, Sr, Mo, and P in benthic and pelagic fish species in the Karatal river, which is fed by melting glaciers from the Dzungarian Alatau in Kazakhstan. In September 2022, 48 fish samples were collected. It has been demonstrated that the accumulation of chemical elements in fish species can be explained by both the physiological parameters of the fish species and the influence of glaciers that feed river habitats. The data presented in this study provide a synergistic view of pollutants affecting fish populations. Benthic fish contained more manganese and strontium than pelagic species, while the mutual accumulation of potassium, chromium, rubidium, and molybdenum was higher in pelagic fish. The synergistic concentration of calcium and phosphorus in pelagic fish was higher than that in benthic species, while the amount of zinc and sulfur was higher in benthic animals. Relatively elevated levels of mercury in fish were found. The study contributes to the discussion about the role of glacial environments in loading pollutants to aquatic systems.

Abstract Knowing the distribution and eco-geography of native Onobrychis altissima and O. cyri in Azerbaijan is critical for the implementation of strategies for their conservation and sustainable use. This study includes 27 specimens from nine wild populations of O. altissima and O. cyri collected from their natural habitats in Azerbaijan. The aims of this study are to provide a detailed morphological and eco-geographic characterization of O. altissima and O. cyri, to determine the distribution and environmental variables that define the eco-geographic zones native to Azerbaijan, and also to determine the priority areas for in situ conservation of native Onobrychis germplasm in Azerbaijan. Besides, research work was carried out for the purpose of clarifying the distribution areas, discovering more resistant species for selection, as well as enriching the genetic resources and Her-barium Fund. The specimens were biometrically assessed using 34 quantitative and 10 qualitative morphological characters. At each site, we recorded eco-geographic data regarding longitude, latitude, altitude, slope inclination, slope orientation, maximum and minimum temperatures, annual precipitation, relief, as well as soil traits including texture, humus, organic carbon, total nitrogen, pH, phosphorus pentoxide, potassium oxide, and magnesium. Cluster analysis of morphological characters showed that the nine populations could be divided into three main groups. Furthermore, principal component analysis (PCA) of eco-geographic data is discussed. The article presents tables and phenograms reflecting some eco-geographic information and a distribution map of the species.

The aims of this study are to provide a detailed morphological and eco-geographic characterization of O. altissima and O. cyri, to determine the distribution and environmental variables that define the eco-geographic zones native to Azerbaijan, and also to determine the priority areas for in situ conservation of native Onobrychis germplasm in Azerbaijan. Besides, research work was carried out for the purpose of clarifying the distribution areas, discovering more resistant species for selection, as well as enriching the genetic resources and Her-barium Fund. The specimens were biometrically assessed using 34 quantitative and 10 qualitative morphological characters. At each site, we recorded eco-geographic data regarding longitude, latitude, altitude, slope inclination, slope orientation, maximum and minimum temperatures, annual precipitation, relief, as well as soil traits including texture, humus, organic carbon, total nitrogen, pH, phosphorus pentoxide, potassium oxide, and magnesium. Cluster analysis of morphological characters showed that the nine populations could be divided into three main groups. Furthermore, principal component analysis (PCA) of eco-geographic data is discussed. The article presents tables and phenograms reflecting some eco-geographic information and a distribution map of the species.","PeriodicalId":11593,"journal":{"name":"Ekológia (Bratislava)","volume":"46 1","pages":"342 - 348"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139191343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract The current study presents data on the structure of populations of an endemic species Phlomis nubilans Zakirov under a drought climate. The rare species P. nubilans belongs to the respective endemic genus of Uzbekistan. We studied the ontogenetic structure of populations, and the current state of P. nubilans populations was estimated based on a set of climate factors. The study focused on the ontogenetic structure of two populations of P. nubilans, revealing that the examined populations grew under drought conditions. The ontogenetic structure was incomplete, that is, it did not include all age groups. Their ontogenetic spectrum was centered and coincided with the characteristic spectrum. The research determined that the ontogenetic type was mature. The studied populations do have not any young plants (juvenile, immature, virginal) due to extreme drought conditions and various factors of elimination, including irregular seed propagation.
摘要 目前的研究提供了干旱气候下特有物种 Phlomis nubilans Zakirov 种群结构的数据。稀有物种 P. nubilans 属于乌兹别克斯坦的特有属。我们研究了种群的个体发育结构，并根据一系列气候因素估计了 P. nubilans 种群的现状。研究重点是两个努比兰牛肝菌种群的个体发育结构，结果表明所考察的种群是在干旱条件下生长的。其本体结构不完整，即不包括所有年龄组。它们的个体发育谱居中，并与特征谱相吻合。研究结果表明，它们的个体发育类型是成熟型。由于极端干旱条件和各种淘汰因素，包括种子繁殖不规范，所研究的种群没有任何幼苗（幼苗、未成熟苗、处女苗）。

Abstract The North African steppe areas represent a heritage of great economic and ecological importance. These areas, which were once prosperous, are currently experiencing significant degradation and a decrease in productivity due to several factors. The objective of this study was to evaluate the dynamics of the steppe vegetation, identify the responsible factors, and present perspectives for their management and restoration. The methodological approach adopted for the characterization of climatic and socioeconomic conditions and the analysis of vegetation dynamics combined classical geomatics methods with a data mining method by mobilizing several sources and on important temporal horizons. This study was optimized by using the Google Earth Engine platform. Results showed that steppe areas are characterized by their plant richness and great potential for resilience despite their low vegetation cover. The analysis of the dynamics of change has highlighted a regressive trend in steppe vegetation during the study period (1995–2020). This study has been able to highlight the extent of the dynamics of the steppes in the study area during the last 26 years and to identify the human activity as the main trigger for the transformation that steppe areas are currently undergoing. Such results improve our knowledge of these areas and open perspectives for their management.
