As a paleoendemic petrophilic species of the foothills of Dagestan Scabiosa gumbetica Boiss, its comprehensive studies are relevant. This work is devoted to the identification of the state of the Tantari cenopopulation of the species and the study of the renewal potential of individuals in the field, in laboratory conditions and through in vitro culture.Material and Methods. Long‐term population studies of Scabiosa gumbetica using geobotanical methods were carried out in the vicinity of the village of Tantari in the Gumbetovsky district of Dagestan. The vital state of individuals was determined by the Zlobin method, while the degree of vitality of individuals was determined according to Ishbirdin. The introduction of the subject into in vitro culture was done according to the generally accepted methodology.Results. A wide range of variation in the characteristics of S. gumbetica individuals characterises the differentiation of ecotopes in which it occurs. The vital analysis of individuals revealed depressive tendencies in the development of the cenopopulation with a low degree of severity. A high value of potential and a low value of real seed productivity were shown – insufficient for successful seed renewal in natural populations. The potential of vegetative renewal of individuals was confirmed, which compensates for the low productivity of natural seed renewal. A scheme of clonal micro‐multiplication of S. gumbetica was developed by cultivating nodal explants on a Murashige‐Skuga medium with the addition of IBA, NAA, BAP and kinetin.Conclusion. Low real seed productivity and depressive tendencies of the vitality of individuals in the Tanari cenopopulation of S. gumbetica indicate the need to develop methods for its conservation. Biotechnological methods can be promising. Studies have substantiated and demonstrated the possibilities of microclonal reproduction by direct organogenesis.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"38 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77939332","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}

Analysis of the distribution and status of ctenophores Вeroe ovata and Mnemiopsis leidyi, and assessment of the parameters of their interaction in the Middle Caspian Sea.Material and Methods. The material was obtained in the western and eastern parts of the Middle Caspian Sea in September–October 2022. Large ctenophores were collected using a big cone plankton net with a 0.5 m2 opening and a 500 μm, mesh size. The number and size of large ctenophores were determined immediately after collection, larvae and eggs were counted in samples fixed with formalin to a final concentration of 4%. Zooplankton samples were collected by the Juday plankton net (0.1 m2 opening, 180 μm mesh size).Results. In September‐October 2022, a developed population of Вeroe ovata with active reproduction was recorded in the waters of the Middle Caspian Sea. The habitat area of B. ovata has significantly expanded to the north compared to 2021. Complete suppression of the Mnemiopsis population by the Beroe was observed on most of the western and eastern shelf, as well. The total number of Beroe reached 48 ind/m2, biomass – 12 g/m2. Single large individuals were found in the north of the Middle Caspian Sea at salinity 5.7 psu. The structure of mesozooplankton was still dominated by the small copepod Acartia tonsa.Conclusion. New data indicate the active development of the Вeroe ovata in the Caspian Sea, which presents a fundamental challenge for the restoration of the Caspian ecosystem. The progressive adaptation of Beroe to the conditions of the Caspian Sea has led to its expansion to the north of the Middle Caspian Sea in areas with low salinity. A complete suppression of the M. Leidyi population by the new alien noted on most of the shelf indicates an increase in its pressure on the Mnemiopsis population compared to the corresponding period of 2021.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"40 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73934583","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}

To identify and describe communities which include Juniperus oblonga on the Gunib Plateau. To conduct a taxonomic, geographical, biomorphological analysis of the flora of these communities.Material and Methods. The research was carried out by the method of the laying of trial plots. 15 geobotanical descriptions were undertaken. Office data processing was carried out using tabular ecological‐phytocenotic analysis. Analysis of the flora of the communities was carried out according to generally accepted methods of floristic research.Results. The flora of the juniper woodlands of the Gunib Plateau is represented by 185 species from 124 genera and 41 families. According to the results of geographical analysis, 19 geoelements were identified from 4 geotypes, of which the species of the boreal group (53.8%) of the Caucasian geoelement (31.9%) are the most represented. There are present rare and disappearing (2.7%), endemic (28.1%) and relict species (14.1%). An ecological‐phytocenotic classification of communities with the participation of Juniperus oblonga on the Gunib Plateau was developed and 4 associations, 5 subassociations and 5 variants were identified. A prodromus was compiled.Conclusion. Sparse juniper forests are one of the main types of vegetation of the Gunib Plateau, constituting a third of the flora of the plateau with a high degree of uniqueness and a complex of abiotic factors that change along the altitudinal gradient, microrelief and slope exposures, which are decisive when dominants change in communities of sparse juniper forests.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"79 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83789338","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}

The aim is to assess the socio‐economic and metropolitan environmental  development  of  border  areas  of  the  Central  Black  Soil region (Belgorod, Voronezh, Kursk regions) in order to develop a model concept.Material and Methods. The study uses a systematic approach through methods of comparative and economic‐statistical analysis. The statistical base employed was the official materials of Rosstat 2016–2020.Results. The calculated integral index of socio‐economic and metropolitan environmental development of the border areas of the Central Black Soil region indicates the presence of four groups of municipalities with high, medium, below average and low levels of development. The socio‐ economic development of border areas is characterised by high spatial heterogeneity and a high degree of concentration of human and economic capital within the agglomerations. There is a polarisation in the considered indicators: while the gap in the private indices is not so significant, it is significant between municipalities. In accordance with our calculations, there is a need to develop a model concept of socio‐economic and metropolitan environmental development of border regions.Conclusions. The level of socio‐economic development of areas is a derivative of the power generated by the metropolitan‐core and is determined by the available local economic potential, the ability of district centres of concentration of business activity to absorb the impacts of the metropolitan centre. Gradual \"filling\" of socio‐economic gaps is possible if the level of development of the metropolitan core and adjacent territories increases, i.e. the territorial spread of the positive socio‐economic effects generated by the metropolis.The work has solved an urgent practice‐oriented task of socio‐economic and geographical research – the assessment of socio‐economic and metropolitan environmental development of border areas of the Central Black Soil region, which provides an opportunity to comprehensively and adequately identify \"strengths and weaknesses\" of the metropolitan development of the regions.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"24 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91085483","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}

The structure of forest communities changes along the altitude gradient, which determines the composition of epiphytic lichens. The aim of the study is to compare the species composition and functional characteristics of epiphytic lichens in Dagestan forests of different formations to identify key differences in the lichen flora.Material and Methods. Data on diversity and structure of 334 species of epiphytic lichens revealed during in field work from 2015 to 2019 were used as material for the work. Statistical analysis and data visualization were performed in Statistica 13.3 and PAST 4.0.Results. The highest number of epiphytic lichens was revealed in forests with complex tree structure with the participation of pine. A decrease of specific species and genera was noted with altitude increase. Cluster analysis of species, genera, reproductive strategies and growth forms showed the proximity of mountain forests (Pineta kochiana and Fageta orientalis) and their distance from lowland forests (Carpineta betulus). The percent  of  species  forming  vegetative  diaspores  increases  in mountain cluster forests. The \"photobiont\" indicator is clearer separated of studied formations. The greatest contribution to the division of the total sample is caused by difference in altitude, grouping the samples into mountainous and lowland.Conclusion.

Analysis of the dynamics of growth and development of anthers of the winter‐flowering shrub Jasminum nudiflorum in the conditions of the Southern coast of Crimea in connection with the determination of an adaptive strategy for the genesis of the male generative sphere of the species.Material and Methods.  The  stages  of genesis  of  Jasminum nudiflorum anthers were determined during the weekly analysis of temporary and permanent  preparations  of  buds  collected  from  June  to  December 2018–2020. The dynamics of the growth of anthers was determined by calculating the relative growth rate (R), based on the actual data of their lengths.Results. The genesis of J. nudiflorum anthers takes 6–7 months and is characterized by alternating periods of decreasing and increasing growth intensity. A high positive correlation was established between the lengths of J. nudiflorum anthers and their development stages (r=0,94). The premeiotic period lasts from the 2nd decade of June to the 3rd decade of August. In it, it is possible to distinguish the resting phase, which falls on the 3rd decade of July – I decade of August, after which the growth and differentiation of anther tissues is activated. During the period of microsporogenesis (1st – 2nd decades of October), the growth intensity reaches its maximum values. The average daily air temperature during this period is +16...+18°C. In the post‐arctic period (2nd decade of October – 3rd decade of December), when the differentiation of the gametophyte occurs, there is a decrease in the relative growth rate of anthers. In winter, the anthers are at the stage of vacuolated microspores, which can tolerate short‐term freezing without reducing the quality of pollen.Conclusions. The strategy of the genesis of the male generative sphere in the winter‐flowering shrub is characterized by alternating periods of increase and decrease of the intensity of their growth, which are timed to certain stages of development and seasons of the year and are adaptive in nature, aimed at reducing the influence of stress from meteorological and climatic factors, which is important for the production of a fertile gametophyte.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"22 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82750513","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}

To summarise information provided so as to allow us to compile a modern understanding of the breeding ranges, abundance and breeding biology of the Great Spotted Eagle Aquila clanga, a rare species in the Altai Territory and the Altai Republic.Material and Methods. While studying the distribution, abundance and nesting biology of the Great Spotted Eagle, we used generally accepted methods with certain modifications. The species was observed during foot and car surveys. To get an idea of the distribution of the spotted eagle in the region, an analysis of available sources was carried out, including materials from the Red Data Book of the Altai Territory and other relevant information resources.Results. Nesting groups of a feathered predator are characterised by uneven spatial distribution. This is due to the habit of the spotted eagle to gravitate to wetlands and floodplain lands in high‐trunk mixed forests, alternating with meadow‐pasture and field landscapes. In ribbon and acquisition forests, as well as in wildlife sanctuaries located on their territory,  there  has  been  a  rapid  trend  towards  a  decrease  in  the population of the species, primarily due to selective felling of vegetation and disturbance of the birds during the nesting period. In this regar, there is a need to expand and deepen ornithological studies aimed at improving environmental measures for the Great Spotted Eagle.Conclusions. Protection of this species should be combined with inevitable criminal or administrative punishment of poachers and illegal forest users, who are involved in destructive environmental activities in the region discussed.  Otherwise,  the  progressive  extinction  of  the  Great  Spotted Eagle population in Altai will reach a critical point in forthcoming years.","PeriodicalId":41300,"journal":{"name":"South of Russia-Ecology Development","volume":"1 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79296612","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}
