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.

Abstract
Compared to the data collected in 2016, pronounced changes in the malacofauna inhabiting the Shershnevskoye Reservoir (city of Chelyabinsk) were discovered in August 2022 at inshore sampling stations near the dam. Mollusks of the family Sphaeriidae have disappeared from the community of bivalves. The species Dreissena polymorpha (Pallas, 1771) of the family Dreissenidae predominated the malacofauna in 2022. Analysis of the size and age structure of the D. polymorpha population showed that the maximum age of mollusks was 5 years. The collected data indicate that D. polymorpha has successfully invaded the Shershnevskoye Reservoir in the period since 2016 and naturalized there.

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.
