The resource melliferous-polleniferous potential of Russian invasive plant species was studied on the basis of the results of melissopalynological (pollen) analysis. The study of the pollen composition of 2121 honey samples from 70 Russian regions made it possible to diagnose the pollen of 26 invasive plants in their composition, 13 of which were resource plants. In the European part of Russia, important melliferous plants were Robinia pseudoacacia L., Gleditsia triacanthos L., Amorpha fruticosa L., Solidago canadensis L., and Ailanthus altissima (Miller) Swingle. Monofloral honey types from these invasive species were obtained mainly in the southern regions. In Siberia, Centaurea scabiosa L., C. jacea L., Echium vulgare L., and Co nium maculatum L. were of resource importance. Monofloral greater and brown knapweed, viper`s bugloss and wild hemlock honey types were found mainly in the regions of Western Siberia. In the Far East, sources of monofloral honey were Nonea rossica Steven and Amoria hybrida (L.) C. Presl. The species Lupinus polyphyllus Lindll. and species of the genus Ambrosia were classified as important Russian polleniferous plants.

On the basis of developed individual-based model and empirical data the importance of anemochory for the dispersal of giant hogweed mericarpia over long distances (up to 55 m from the parent plant) was proved. The use of cellular automate for modelling of the plant coenopopuation area increase allowed to reveal the influence of weather condition, number and spatial distribution of hogweed plants in the period of the beginning of introduction on the rate of invasion. Verification of the results of the cellular automaton work based on satellite images and field observations showed a significant level of compliance of theoretical calculations and observed results. The logistic functions parameters describing the change in the area of giant invasive hogweed stands were determined. A retrospective analysis of satellite images of model plots, starting from the 90s of the 20th century, showed an annual increase in the area of hogweed coenopopulations by 20% in the exponential population growth phase. A significant variability in the rate of invasion (from 5% to 70% per year) depended on the initial conditions and stage of invasion, usage modes and ecological capacity of the available sites.

Among invasive species there is a special group so named cryptic species for which morphological identification is very difficult. This review is devoted to analysis of the dispersal routes of two copepod cryptic species complexes into aquatic ecosystems. Eurytemora carolleeae introduction was revealed in 2007 with bar-code. The species was described as a new taxon; its distribution was also studied using morphology. Biological invasions of two other Copepod species Acanthocyclops americanus and Eurytemora caspica were mainly studied using morphological methods since the species have already been described. At the same time, to confirm their distinctions from local forms, molecular genetic tools were also used. Two scenarios resulting from cryptic species’ invasions and their competitions with native species were the partly ( E. carrolleeae ) or full displacement ( A. americanus ). Example: the invasion of Eurytemora carolleeae into the Baltic Sea and the Atlantic coast of Europe. When assessing the possible negative impact of invasive species on competitors, the most attention should be paid to predator species. Identification of cryptic species significantly complicates the situation with the assessment of bioinvasion and needs the use of molecular methods.

For the first time the research focuses on studying the size and weight characteristics of the alien species in the Sea of Azov - bivalve mollusc Anadara kagoshimensis (Tokunaga, 1906). The relationship between allometric parameters of the mollusc (size and weight) were approximated by the power function. The maximal coefficient of determination is found for the power dependence of the total weight of the anadara on the width of the shell, with minimum coefficient of determination depending on the height of the shell. The maximum coefficient of determination is obtained for the power dependence of the raw weight of soft tissues of anadara on the length of its shell, with the minimum coefficient of determination depending on the width of the shell. The ratio of dry and raw weight of soft tissues is 0.16. Under comparison of the different environmental areas of anadara in the Black, Aenean seas and the Sea of Azov, the hatchery housing of mollusks in waters with moderate salinity is found to be the most favorable condition for their maximal growth.

Currently, 10-15% of invasive plant species are recorded in alien floras of all inhabited regions of the world, and their proportion is constantly growing. A particular problem is naturalization of alien species in the regions with high levels of endemism and species diversity, such as the Republic of Altai. We have been studying the alien flora of the Republic of Altai since the beginning of the 21st century. The ranges of 67 invasive species belonging to 57 genera and 20 families have been identified. Most of the species have been known on the territory of the Republic of Altai since the 20th century, 10 species have penetrated here in the 21st century. The main method of penetration (vector) is accidental introduction. In all areas, at least singly, there are 5 species: Amaranthus retroflexus, Bunias orientalis, Matricaria discoidea, Melilotus officinalis, Tripleurospermum inodorum . The orographic and climatic features of the area predetermine a greater susceptibility to invasions for the northern regions and a lesser one for the southeastern regions. Eighteen species are distributed only in the northern regions. Almost all species are found in Gorno-Altaisk and Mayma district, the least number of species - in Kosh-Agach district, which is characterized by the most severe climatic conditions. Thirty five species are invasive in Siberia, 11 species are among the hundred most aggressive species in Russia. Based on our own long-term research, taking into account the analysis of available publications and stock materials (Herbarium of the Central Siberian Botanical Garden of the Siberian Branch of the Russian Academy of Sciences and Gorno-Altai State University), as well as other available data (iNaturalist, GBIF), maps of the ranges of invasive plants of the Republic of Altai were compiled. For each species, all known localities are given, indicating administrative regions, settlements, river valleys, etc., the time of discovery is noted, and links to the source are indicated.

The study of intraspecific variability of alien plants is crucial for revealing the patterns of their microevolution in the secondary distribution range and predicting the possibility of further dispersal and the ability to invade natural plant communities. It is still unclear how a genetically impoverished initial invasive population forms a taxon with a range exceeding the natural range of the species and, therefore, adapted to more diverse ecological and climatic conditions. Boxelder, Acer negundo L., is a remarkable object of study in this respect. The secondary distribution range of this North American species covers all regions of our plane excluding Antarctica. In Russia it spread from Kaliningrad to Vladivostok, formed invasive populations in all eight Federal Districts and was included in the TOP 100 of the most aggressive invasive species of the country. The intraspecific variability of its biomorphological characters was studied by us earlier, and the results of the study of genotypic variability are presented in this article. Invasive populations of A. negundo located along the Trans-Siberian Railway from Moscow to Vladivostok (9288 km) were examined. We isolated DNA from 38 specimens collected along the Trans-Siberian railway in Vladimir and Kostroma Regions, Republic of Tatarstan, Perm Region, Novosibirsk Region, Krasnoyarsk Territory, Amur Region, and Primorskii Territory. By the ITS 1-2 nuclear DNA site, specimens of Acer negundo from the Russian part of the secondary distribution range showed very high similarity with each other, but with 100% bootstrap support separated from specimens from the natural distribution range. According to the chloroplast high-variable trnL-trnF site, the specimens were divided into two clades that weakly correlated with the geographical origin of the specimen. Separate subclades with high bootstrap support are formed by the plants: 1) from Tatarstan (Kazan and Nizhnekamsk), 2) from Perm and Novosibirsk, and 3) samples from Krasnoyarsk. The haplotype network constructed at the trnL-trnF site also demonstrated the genetic specificity of the samples from Tatarstan. We hypothesized that only a few genotypes of A. negundo with a high degree of invasive activity were dispersed along the Trans-Siberian Railway (and possibly throughout all Russia). Other genotypes, including those that entered the territory of the former Russian Empire earlier, have not shown the ability to invade natural plant communities and occur rather rarely.

Anadara kagoshimensis (Tokunaga, 1906) is an invasive species that has successfully colonized the waters of the Black Sea and the sea of Azov, despite the significantly lower salinity level of these waters in comparison with the native region. The morphological and morphometric characteristics of bivalve mollusk A. kagoshimensis erythrocytes were analyzed by light microscopy during adaptation to hypo- and hyperosmotic experimental conditions. The control group of mollusks was kept at 18‰ salinity. Experimental groups were acclimated to 8, 14, 35 and 45‰ salinity. A decrease of salinity was achieved by diluting seawater with distilled water at a rate of 1.5±0.5‰ per day. Sea salt was added to each aquarium to increase salinity. Salinity was increased at a rate of 2.5±0.5‰ per day. Exposure period was 2 days. It has been shown that the salinity range of 14-35‰ is natural for ark clam. No significant changes in cell morphology were observed under these conditions. At the same time, environmental salinity levels of 8 and 45‰ caused obvious stress: cellular anomalies appeared, and the linear characteristics of erythrocytes were changed. However, cell lysis did not occur, the values of the specific surface area and nuclear-cytoplasmic ratio did not change. The results of the present work indicate the ability of the arc clam to exist for some time in regions with extremely low and high salinity of the aquatic environment.

However, cell lysis did not occur, the values of the specific surface area and nuclear-cytoplasmic ratio did not change. The results of the present work indicate the ability of the arc clam to exist for some time in regions with extremely low and high salinity of the aquatic environment.","PeriodicalId":44218,"journal":{"name":"Russian Journal of Biological Invasions","volume":"18 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79650365","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}

Introduction of alien species to marine islands leads to destabilization of the unique ecosystems, which are characterized by a high level of ecological vulnerability. A review of alien mammal species in the insular theriocomplexes of the Northwestern Pacific was made and the results of a massive invasion that occurred in the recent 150 years were analyzed. Currently, 43 alien species belonging to 19 families of 7 mammal orders live on the islands of the Northwest Pacific, among which 9 are included in the list of the 14 most dangerous invasive species of the world, and 8 of the 10 most dangerous introduced mammals of the Russian Federation inhabit the islands of the Russian segment of this region.
