Aim . The unique gene pool of indigenous breeds in the Dagestan Caucasus is threatened by the increasingly widespread use of commercial breeds, which in turn risks narrowing the genetic base necessary to increase and maintain existing genetic diversity. For this reason, our research aimed to study the polymorphism of the PRL, PIT‐1, GH genes in red steppe and Caucasian brown cattle raised in the conditions of Dagestan. Methods . Genotyping of red steppe and Caucasian brown cattle was carried out using PCR‐RFLP methods. Using these methods, genetic analysis was carried out and polymorphism of the prolactin, somatotropin and pituitary‐specific transcription factor genes was studied. Results . As a result of the genotyping of an experimental group of red steppe cattle, it was found that the distribution of two alleles and three genotypes (PIT‐1A and PIT‐1B; PIT‐1AA, PIT‐1BB, PIT‐1AB) of the PIT‐1 gene has a specific character. The specificity of the allelic spectrum of the PRL gene is expressed in the high (0.84) frequency of occurrence of the PRLA allele and low (0.16) frequency of the PRLB allele. This is reflected in the presence of homo‐ and heterozygous genotypes with a frequency of occurrence of 73.0; 23.0; 4.0 %, respectively. Conclusion . Applied genetic approaches to improve the productive and breed qualities of livestock, which are modern and based on a more complete analysis of the genetic diversity and genotype of the studied populations, contribute to the conservation of zoned breeds. At the same time, intrapopulation variability and good adaptability should ensure the sustainable development of dairy cattle breeding in various climatic zones.
的目标。达吉斯坦高加索地区独特的地方品种基因库受到日益广泛使用商业品种的威胁,这反过来又有可能缩小增加和维持现有遗传多样性所必需的遗传基础。因此,本研究旨在研究达吉斯坦条件下饲养的红草原牛和高加索褐牛PRL、PIT‐1、GH基因的多态性。方法。采用PCR - RFLP方法对红草原牛和高加索褐牛进行基因分型。利用这些方法进行了遗传分析,研究了催乳素、生长激素和垂体特异性转录因子基因的多态性。结果。对红草原牛试验组进行基因分型分析,发现红草原牛的2个等位基因和3个基因型(PIT‐1A和PIT‐1B;PIT‐1基因的PIT‐1AA, PIT‐1BB, PIT‐1AB)具有特异性。PRL基因等位基因谱的特异性表现为PRLA等位基因出现频率高(0.84),PRLB等位基因出现频率低(0.16)。这反映在同源和杂合基因型的存在上,发生频率为73.0;23.0;分别为4.0%。结论。应用遗传方法来提高牲畜的生产和品种质量,这些方法是现代的,并且基于对所研究群体的遗传多样性和基因型的更完整的分析,有助于保护分区品种。同时,种群内变异性和良好的适应性应保证奶牛养殖在不同气候带的可持续发展。

Aim . Agroecological assessment of herbicides application on crops of soybean variety Arleta in the central zone of Krasnodar Territory. Materials and Methods . The experiments were carried out on the experimental field of the Federal Research Centre of Biological Plant Protection in 2022 according to the methodological recommendations for testing herbicides in agriculture. Herbicides from different chemical classes were used in the experiment. Efficiency was assessed by the difference in weed and soybean grain yield in comparison with the control. The comparative ecotoxicological load of preparations was carried out according to the ecological load and the coefficient of selectivity of action for the soil. Results . Weed species in the experiment were highly effectively suppressed by the herbicides Pulsar, BP, Pivot, VK and a mixture of Bazagran, BP + Zellek Super, and KE (88–98 %). When using Dual Gold, EC, Frontier Optima, EC and Proponit, and EC before the soybean shoots, the biological efficacy was lower. The preparations Pulsar, BP and Pivot, and VK, in comparison with other herbicides, had a lower level of environmental load and a high coefficient of selective action and meet modern safety requirements for the natural environment. Conclusions . In order to protect the environment when choosing herbicides for application on soybean crops in the central zone of Krasnodar Territory, they should be comprehensively selected taking into account the ecotoxicological load of the preparations.

Aim . To identify the composition and features of the spatial structure of microfouling (microplaston) during the early stages of colonisation of the surfaces of artificial polymer films (LDPE) in the natural habitats of the Miass River and Lake Turgoyak (Southern Urals). The early stages of polymer microfouling which create the basis for further complexity of its spatial mosaic are considered, taking into account the surface microlandscape and the possibilities it creates for the location of community components. Materials and Methods . Fragments of polymer films (LDPE) manufactured for household use were collected in the waters of the Miass River and Lake Turgoyak in June 2023. Samples were selected that were exposed in natural reservoirs for at least several months. Analysis of the composition, structure and spatial organization of microplastonic communities was carried out using light and SEM microscopy. Results . The microplaston in the early stages of growth varied significantly among the habitats studied. On LDPE films from the Miass River they were dominated by sessile armored amoebae (Granofilosea: Microgromiidae), attached diatoms (Bacillariophyta: Achnanthaceae, Cocconeidaceae) developed as a mass and encrusting green microalgae (Chlorophyta, Charophyta) were also found. In Lake Turgoyak cortical green microalgae clearly dominated, together with other diatoms (Bacillariophyta: Rhopalodiaceae, Cocconeidaceae). Trichome and coccoid forms of cyanoprokaryotes (Cyanobacteria: Pseudanabaenaceae, Rivulariaceae, Chamaesiphonaceae, Microcystaceae) were also abundant. The colonisation of films by individual species varied among habitats and also depended on the surface microrelief. Conclusion . Analysis of the microplaston of LDPE films in hydrologically different habitats demonstrated the features of early colonisation of these substrates, the biotope‐specificity of the species and spatial structure of communities, as well as the organisation of colonial settlements of a number of species.

Aim . To investigate the molecular-epidemiological characteristics of the territorial distribution of HIV infection in the Sakhalin region. Materials and Methods . A comprehensive analysis of molecular-genetic characteristics of HIV-1 and clinical-epidemiological data of 64 HIV-infected residents of the Sakhalin region was conducted. Nucleotide sequences of the pol gene region encoding protease, reverse transcriptase, and integrase of HIV-1 were obtained by sequencing amplified virus fragments. Genotyping, phylogenetic and mutational analyses were performed using specialized software resources. Results . Among the HIV-1 cases studied, the HIV-1 subtype A6 was detected in 81.3 % of cases, with 58.4 % of them reliably clustering into closely related HIV groups, indicating the development of internal epidemic networks of infection transmission. Additionally, HIV-1 CRF63_02A6 and 06_cpx were detected in 4.7 % of cases each, subtype B and B/G in 3.1 %, subtypes C and A1 in 1.6 %. HIV-1 A6, B/G variants, and subtype A1 similar to Mediterranean HIV were detected in the MSM group. In 10.8 % of cases, treatment-naive patients had HIV-1 with the K103N mutation, and in one case, multiple drug resistance was identified. Conclusion . The contemporary territorial epidemic of HIV infection in the Sakhalin region is characterised by the presence of internal epidemic networks and the registration and spread of imported HIV. Key population groups with HIV infection require special attention due to the documented transmission of ART-resistant viruses. Studying the peculiarities of HIV infection spread in individual regions of Russia is important for the development of effective measures aimed at ending HIV transmission in the country.
的目标。目的:了解库页岛地区HIV感染地域分布的分子流行病学特征。材料与方法。对库页岛地区64名hiv感染居民的HIV-1分子遗传特征和临床流行病学资料进行了综合分析。通过对扩增的病毒片段测序,获得了编码HIV-1蛋白酶、逆转录酶和整合酶的pol基因区域的核苷酸序列。使用专门的软件资源进行基因分型、系统发育和突变分析。结果。在研究的HIV-1病例中,有81.3%的病例检测到HIV-1 A6亚型,其中58.4%的病例可靠地聚集在密切相关的HIV群体中,这表明感染传播的内部流行网络已经形成。此外,HIV-1 CRF63_02A6和06_cpx分别在4.7%的病例中检测到,B和B/G亚型占3.1%,C和A1亚型占1.6%。在MSM组中检测到HIV-1 A6、B/G变体和A1亚型与地中海HIV相似。在10.8%的病例中,未接受治疗的患者携带K103N突变的HIV-1,其中一例被鉴定出多重耐药。结论。目前,萨哈林地区境内艾滋病毒感染流行的特点是存在内部流行病网络以及输入性艾滋病毒的登记和传播。艾滋病毒感染的关键人群需要特别关注,因为有记录的耐抗逆转录病毒传播。研究俄罗斯个别地区艾滋病毒感染传播的特点,对于制定旨在结束该国艾滋病毒传播的有效措施非常重要。

Aim . The aim of the work is to study the fish helminth fauna of Lake Sevan basin. Material and Methods . Fish helminths and molluscs were collected from the Lake Sevan basin. A total of 214 specimens of fish were studied. The collection, cameral processing and determination of the material was carried out according to generally accepted methods. Statistical processing of the material was carried out using the BioStat 2009 computer program. 124 specimens of molluscs were examined from the littoral of the Lake Sevan. The collection and identification of molluscs was carried out according to generally accepted methods. The work was carried out at the Scientific Centre of Zoology and Hydroecology of NAS of the Republic of Armenia. Its own collections have been used as material. Results . Trematodes, cestodes, nematodes and acanthocephals were found аs a result of studies of fish from the Lake Sevan basin. The total infestation of the fish by helminths was 27.1 %. Six species of helminths have been identified, two of which are the first to be recorded in new hosts in Armenia. The higher infestations of fish were noted by metacercariae of the trematode Diplostomum sp. and plerocercoids of the cestode Ligula intestinalis. A brief analysis of the infestation of fish by the detected helminths is given. Conclusion . The species composition of the helminth fauna of fish in the Lake Sevan basin was studied. Pathogens of dangerous helminthiases causing the death of fish have been noted. Studies of the helminth fauna of fish in the Lake Sevan basin are relevant and will be continued. Most of the species of fish affected by helminths are of economic importance. Some species of the helminths which were found are very invasive and cause great damage to the fisheries of the republic.

Aim . To investigate the features of the abiotic (soils) and biotic (flora and vegetation) components of ruderal communities (Ruderalophyton) of the urban ecosystem in the conditions of the Rostov agglomeration. Material and Methods . The morphoecological analysis of the flora (144 species of vascular plants) was shown. Data were obtained of the characteristic growth features of roadside communities of the Southern Federal University Botanical Garden (floristic diversity of 53 species) and of ruderal communities of new residential building plots in the peripheral part of the city and abandoned houses in the central part of the city. Results . Abiotic conditions for the habitats of ruderal plants are no longer natural because the local Chernozem root‐inhabited and humusaccumulative surface horizons have been almost completely stripped away. At the same time, cenotically the communities are multicomponent and floristically saturated with high projective coverage. During the process of anthropogenic vegetation evolution, a new type of cenosis has formed, which is adapted in ecological succession processes to all components of the urban ecosystem. Conclusion . The ruderal vegetation of the Rostov agglomeration is particularly resistant. It develops urban horizons, which are characterized by a high proportion of anthropogenic inclusions; household, and industrial waste, which is often contaminated with organic and inorganic pollutants. Plant communities developing on such substrates are multicomponent, floristically saturated and have formed a high degree of projective cover.
的目标。研究罗斯托夫集聚区城市生态系统中原生植物群落(Ruderalophyton)的非生物(土壤)和生物(植物和植被)组成特征。材料和方法。对144种维管植物的区系进行了形态生态学分析。获得了南部联邦大学植物园路边群落(53种植物多样性)、城市外围新建居民楼地块和城市中心废弃房屋的乡村群落的生长特征数据。结果。原生植物栖息地的非生物条件不再是自然的,因为当地的黑钙土根系和腐殖层几乎完全被剥夺了。同时,群落在地理上是多组分的,植物区系饱和,投影盖度高。在人为植被演化过程中,形成了一种新的植被类型,它在生态演替过程中适应了城市生态系统的各个组成部分。结论。罗斯托夫地区的原始植被特别具有抵抗力。它发展了城市地平线,其特征是高比例的人为包裹体;经常被有机和无机污染物污染的家庭和工业废物。在这些基质上发育的植物群落是多组分的,植物区系饱和的,并形成了高度的投影覆盖。

Aim . To identify complexes of gall‐forming insects and mites in the fauna of Dagestan, which, together with other inhabitants of galls, are evolutionarily associated with common plant species and genera. Materials and Methods . The materials were collected in the plains and mountains of Dagestan. Standard methods were used: inspection of plants, search and mass collection of galls; breeding imago and production of preparations of larvae and adults. Results . Assemblages of gall midges (Diptera, Cecidomyiidae), gall wasps (Hymenoptera, Cynipidae), psyllids, aphids (Hemiptera, Aphalaridae, Psyllidae, Aphididae) and gall four‐legged mites (Acari, Eriophyidae) dominate. Additionally, for the fauna of Dagestan, 7 species of 5 genera Eriophyidae and 24 species of 12 genera of insects were identified, including 16 species of 7 genera Cecidomyiidae. Newly recorded for the fauna of Russia are 3 species of 2 genera of mites and 13 species of 8 genera of gall midges: Aceria labiatiflorae (Thomas), A. thomasi (Nalepa), Paraphytoptus chondrillae (Canestrini), Contarinia cardariae Fedotova, C. desertorum Marikovskij, Arthrocnodax chondrillaphylus Fedotova, A. saliciphilus Fedotova, A. origani Fedotova, A. thymiphilus Fedotova, Ozirhincus longicollis Rondani, Dasineura scorzonerifloris Fedotova, Jaapiella chondrillae Skuhravá, Spurgia seguierianae Fedotova, Euphorbomyia loewii (Mik), Marikovskiana dentipes Marikovskij. Larvae of predatory gall midges are almost always found in mite galls. Conclusion . Information about the diversity of gall‐forming complexes in Dagestan will be useful for assessing evolutionary relationships between them and plants and will give an idea of the richness of the fauna in the organisation of protected natural areas and recreational zones.

Aim . Study of the structure of intra‐ and interpopulation variability of Salvia canescens C.A. Mey. along an altitudinal gradient. Material and Methods . To study the morphological traits of Salvia canescens, a generative shoot was used as a «module». In four geographically isolated populations of the species, one generative shoot from 30 individuals was taken. 11 signs were taken into account on the shoots. Statistical analysis of the obtained data was carried out using the Statistica 5.5 program. The levels of variation were assessed according to G.M. Zaitsev. Results . The structure of intra‐ and interpopulation variability of S. canescens, a characteristic representative of mountain‐xerophyte vegetation and an endemic of the Greater Caucasus, was studied. According to the data obtained, the mean values of most of the studied traits of S. canescens increase with altitude. The variability of the studied traits of the species, both intra‐ and interpopulation, has an average and high levels. Most of the traits of S. canescens are positively correlated with each other at the p≤0.05 level. All traits, except for the number of internodes and leaves, are in a positive significant correlation (p≤0.001; p≤0.01) with height above sea level. The results of one‐way ANOVA and regression analyses showed significant differences between populations for most traits of the generative shoot. The maximum differentiation of populations was noted according to the traits «mass of stems» and «mass of inflorescences». Conclusions . The intra‐ and interpopulation variability of the morphological traits of Salvia canescens revealed along the altitudinal gradient is due to the ecological conditions of the species' habitat. The variability of the traits and the increase in the parameters of the generative sphere reflect the adaptation of the species along the altitudinal gradient.
的目标。鼠尾草种群内和种群间变异结构的研究。沿高度梯度的材料和方法。为研究鼠尾草(Salvia canescens)的形态特征,以生芽为“模块”。在四个地理上孤立的种群中,从30个个体中采集了一个生殖芽。拍摄时考虑了11个迹象。使用Statistica 5.5程序对所得数据进行统计分析。变异程度是根据扎伊采夫的说法进行评估的。结果。本文研究了大高加索地区典型的山地旱生植物canescens的种群内和种群间变异结构。根据所获得的数据,所研究的黑松大部分性状的平均值随着海拔的升高而增加。所研究的物种性状在种群内和种群间的变异性均为平均和高水平。在p≤0.05水平上,黑松大部分性状之间呈显著正相关。除节间数和叶片数外,其余性状均呈显著正相关(p≤0.001;P≤0.01)。单因素方差分析和回归分析结果显示,种群间生殖芽的大部分性状存在显著差异。根据“茎质量”和“花序质量”的性状,可以观察到种群的最大分化。结论。鼠尾草(Salvia canescens)种群内和种群间形态特征在海拔梯度上的变异与生境的生态条件有关。这些性状的变异和生殖圈参数的增加反映了物种在海拔梯度上的适应性。
