Abstract
In 1990–2020, long-term field observations in the Transbaikal region (Siberia, Russia) revealed a range expansion of the nemoral butterfly species Limenitis sydyi (Lepidoptera, Nymphalidae) further into Siberia (120° E to 110° E). This species had not been registered to the west of the Chita–Kyra longitudinal line (112° E) before the 2000s, but subsequently became rather common in the environs of the city of Chita. Its first occurrence in the Republic of Buryatia (110° E) was recorded in 2012. This species prefers the sparse-growth forests dominated by larch (Larix sp.) and birch (Betula pendula Roth) that commonly occur in the second-order river valleys at elevations of 400–600 m, whereas the broader and narrower river valleys are only marginally suitable for this nemoral species. Additionally, rather high air humidity levels are critical to L. sydyi during particular periods of its life cycle (May–June and September), as well as a snow depth of at least 10–20 cm.

Abstract
The article presents results of studying the distribution of alien species on the territory of six districts of Zhetysu oblast, located in the Southeastern Kazakhstan. The data obtained will make it possible to summarize up-to-date information about the state of ecosystems with invasive plant species, predict their further spread, and develop a strategy to control them. The objects of research were natural ecosystems of Zhetysu oblast, confined to the Balkhash-Alakol and Zhongar-Alatau floristic districts. To identify alien species, monitoring sites were laid with the calculation of native species, introduced species, the species prone to naturalization, and those with self-seeding. The aggressiveness of naturalized species was assessed according to a modernized scale developed at the Institute of Botany and Phytointroduction, Committee of Forestry and Wildlife, Ministry of Ecology, Geology, and Natural Resources of the Republic of Kazakhstan. The territory under study includes two State National Nature Parks and a State Nature Reserve. Eighty-one alien species of woody plants have been identified within settlements and adjacent territories. Some of them are included in the cultivated flora, which do not show a tendency to naturalization in the region. Seventeen species of alien woody plants have been identified in natural ecosystems, which have the potential for naturalization with a high propensity for seed and vegetative reproduction. The percentage of sites with the presence of invasive species varies from 61 to 91%. The highest aggressiveness score (6–8) was assigned to six species: Acer negundo L., Ulmus pumila L., Quercus robur L., Prunus × domestica, Fraxinus pennsylvanica, Ulmus laevis Pall.. Despite the fact that, in the Alakol and Sarkand districts, most of the territory falls within the dry-steppe and semidesert zones, only 8.6% of sites without types of invasive fraction were noted, owing to widespread dispersion of particularly aggressive “edificators”: A. negundo, U. pumila, etc. All identified species mesophytic by their nature in the secondary range show themselves highly adaptive, plastic, and competitive in xerophytic conditions.

Abstract
The euryhaline species Eurytemora velox (Lilljeborg, 1853) is an active invader like some other Eurytemora species. Having Ponto Caspian origin, it has been actively spread in fresh and brackish waters throughout Europe during recent decades. At present, the species is found even in Western Siberia. No one record of this species outside of Europe and Western Siberia was done. This paper presents finding of mitochondrial haplotype E. velox in North American waters by molecular-genetic methods with morphological identification. This specimen has nITS genes of north Atlantic American E. cf. affinis and mixed E. velox–E. cf. affinis 18S rRNA gene. We suppose it is result of interspecies hybridization between European E. velox and North American E. cf. affinis. Possibly E. velox was invaded North America with the ballast water of ships from Western Siberia. What is surprising, hybrid of the same two species was observed in the Ural, whereas E. cf. affinis was never found outside of the North American Atlantic coast.
摘要极性水生物种 Eurytemora velox（Lilljeborg，1853 年）与其他一些极性水生物种一样，是一种活跃的入侵者。它原产于里海蓬岛，近几十年来在欧洲的淡水和咸水中积极扩散。目前，甚至在西西伯利亚也发现了该物种。该物种在欧洲和西西伯利亚以外的地区没有任何记录。本文通过分子遗传学方法和形态鉴定，在北美水域发现了线粒体单倍型 E. velox。该标本具有北大西洋美洲 E. cf. affinis 的 nITS 基因和 E. velox-E. cf. affinis 混合的 18S rRNA 基因。我们认为这是欧洲 E. velox 与北美 E. cf. affinis 种间杂交的结果。可能是 E. velox 随来自西西伯利亚的船舶压舱水入侵北美。令人惊讶的是，在乌拉尔地区发现了这两个物种的杂交种，而在北美大西洋沿岸以外的地区却从未发现过 E. cf. affinis。

Abstract
The multidecade, seasonal, and interannual variability of hydrometeorological parameters of the Black Sea has been analyzed with reference to the population dynamics of invasive ctenophores. Polynomial approximations of average annual time series indicate a nonlinear character of the long-term variability of the studied parameters. Two 20- and 40-year intervals with multidirectional trends of parameter changes have been revealed. The effect of variability of abiotic factors on the two main ecosystem drivers, i.e., invasive ctenophore Mnemiopsis leidyi A. Agassiz, 1865 and its predator Beroe ovata Bruguière, 1789, has been analyzed. M. leidyi invaded the Black Sea in the 1980s, followed by the B. ovata invasion in the 1990s. The M. leidyi invasion caused degradation of the ecosystem at all trophic levels, including fish resources. The subsequent introduction of its predator, B. ovata, provided a significant restoration of the ecosystem and fish resources in the Black Sea; this process still continues in the Sea of Azov. The interannual dynamics of both ctenophores follows water temperature changes, but only if it varies within the limits favorable for these species. In the case of exceeding these limits, a sharp reduction of their population magnitudes occurs.

Abstract
A “blacklist” of the flora of Orenburg oblast, including 63 species of invasive plants, was compiled. According to the recommendations for the maintenance of regional black books, the blacklist species are divided into four groups according to their invasive status. Ten key species (status 1) are able to change the structure and composition of plant communities, 12 species of invasive status 2 are actively naturalizing in natural and seminatural habitats, 23 species of invasive status 3 have dispersed in anthropogenic habitats. Eighteen species are potentially invasive (status 4). The article is a phase of preparation of the regional Black Book of Flora of Orenburg Oblast and contributes to the study of invasion processes in the Southern Urals and in the Russian Federation in general. The information can be used for taking measures of verification of the number of dangerous invasive species in order to reduce ecological and economic damage due to their invasions.

Abstract
The issue of biodiversity conservation is of great importance. Plant species under threat of extinction are being studied especially carefully, and the cases of degradation of phytocenoses are being investigated. Invasive flora needs to be assessed in nature conservation areas. One of the reasons for the loss of unique natural ecosystems is the invasion of alien organisms, which explains the relevance of the study. The main purpose of this publication is to study the spread of invasive plant species on the territory of the nature sanctuary “Forested Ravine near the Village of Vlasievo” in Moscow oblast. During the field routes in 2017–2022, various biotopes were examined on an area of about 98 ha. The invasive flora includes 15 species, among which Heracleum sosnowskyi is the most active. Assessment of the degree of naturalization of invasive species in protected areas showed that in most species this process is slower than on average in Moscow oblast, in the neighboring Ryazan oblast, and in general in Central Russia. Probably, this trend is due to a weak degree of anthropogenic disturbance of the territory and a low number of alien individuals. At the same time, the expansion of H. sosnowsky was noted in the protected areas, leading to a partial change in the vegetation cover and the composition of the native flora, including rare and protected species. Satellite monitoring made it possible to determine the approximate period of penetration of H. sosnowskyi and to estimate the rate of its spread across protected areas. The identified alien taxa, namely, Acer negundo, Amelanchier spicata, Impatiens parviflora, Echinocystis lobata, Bidens frondosa, Erigeron annuus, and E. canadensis, are among the 100 most dangerous invasive species on the territory of the Russian Federation, which are capable of increasing the invasive potential in the case of violations of the environmental regime of protected areas.

Abstract
The freshwater gastropod mollusk Lithoglyphus naticoides (C. Pfeiffer, 1828) naturalized successfully in the Rybinsk Reservoir and in the Uglich Reservoir in 2005–2011 and 2013–2015, respectively. The aim of this work is to study the structure of trematode communities in settlements of L. naticoides formed by 2019 in the upper parts of these water bodies. It is found that, in both reservoirs, the species composition of trematodes is similar and includes Apophallus muehlingi (Jägerskiöld, 1899), Apophallus (=Rossicotrema) donicus (Skrjabin et Lindtrop, 1919), Parasymphylodora markewitschi Kulakowskaja, 1947, Nicolla skrjabini (Iwanitzky, 1928), and Sanguinicola volgensis (Razin, 1929). The density of L. naticoides varies from 30 to 50 ind./m2 in the shallows of the Rybinsk Reservoir and from 50 to 520 ind./m2 in the Uglich Reservoir, where the mollusk is found at the depth of 2–9 m. In August 2019, the prevalence of parthenitae varied at different degrees even in relatively flowing upper parts of the reservoirs similar in hydrological characteristics: Apophallus spp. (32.01 and 11.45%), P. markewitschi (9.14 and 7.63%), N. skrjabini (16.57 and 7.63%), S. volgensis (19.43 and 63.36%). In the Uglich Reservoir, Xiphidiocercaria sp. (9.16%) has been recorded, though their species has not yet been determined. A single case of mixed infection with parthenitae of trematodes (Sanguinicola + Nicolla) was recorded in the Rybinsk Reservoir in 2019. In the Uglich Reservoir, mixed infection with two species of parasites is more common (Parasymphylodora + Xiphidiocercaria, Sanguinicola + Xiphidiocercaria, Sanguinicola + Parasymphylodora, Sanguinicola + Nicolla). Owing to the high occurrence of some trematodes, L. naticoides is able to have a significant impact on the ecosystems of reservoirs by the development of foci of the helminthoses even with a relatively low size of its populations.

Abstract
Clams of the genus Corbicula were discovered for the first time in the downstream of the Don River in the area of the warm channel of the Novocherkassk State District Power Plant in 2017. They were identified as Corbicula fluminea according to conchiological features. The objective of this study is to confirm the species identification using the molecular genetic methods and determine the morphotype by shell morphometric indices: frontal (D/L) and sagittal (H/L) curvature (=Index of Roundness) and convexity ((H + D)/L). According to the results obtained, the Asian clam was assigned to the European invasive lineage of the FW5 haplotype, taxonomically assigned to C. fluminea and morphologically to the R morphotype.
摘要 2017 年，在顿河下游新谢尔卡斯克国营地区发电厂温水道区域首次发现了蚬属。根据贝壳学特征，它们被确定为Corbicula fluminea。本研究的目的是利用分子遗传学方法确认物种鉴定，并通过贝壳形态指数确定形态类型：正面（D/L）和矢状（H/L）弯曲度（=圆度指数）和凸度（（H + D）/L）。根据所得结果，亚洲蛤蜊被归入 FW5 单倍型的欧洲入侵系，在分类学上被归入 C. fluminea，在形态学上被归入 R 形态型。

Abstract
The age and sex composition of the schools, food activity, the age of sexual maturity, breeding period and fecundity of the alien species Prussian carp indicate the presence of favorable environmental conditions for its wide distribution in the reservoirs of Armenia. The ratio of female/male of Prussian carp in most of the studied reservoirs was 3 : 1; most of the fish were diploids. The age composition of Prussian carp usually has 4 age groups, with maximum of 7 groups, and a minimum of 3 age groups. The age of sexual maturity of Prussian carp differs in the northern (1+ to 4+) and southern (0+ to 3+) populations in Armenia, as well as in flowing and stagnant water bodies. In some reservoirs, the percentage of Prussian carp in catches has increased over the past decades, which negatively affects the local fish species composition. This fact may indicate the formation of the invasive populations of Prussian carp in Armenia.
