Floristic descriptions and analysis of the soil by the level of activity of enzymes (invertase, protease, phosphatase) were carried out using standard methods. The species diversity of vascular plants in the areas under study constituted 64 species. The dominant plant species in the ash-leaved maple communities were identified. Under the canopy of A. negundo , ruderal species - Cirsium setosum, Elytrigia repens, Lamium album, Urtica dioica, and Taraxacum officinale - dominate, while in the outer zones, the proportion of meadow species increases - Achillea millefolium, Dactylis glomerata, and Festuca pratensis .

Pfeiffer, 1828) naturalized in the Uglich Reservoir relatively recently (in 2013-2015). The main objective of this study is a comparative analysis of the species diversity and structure of trematode communities in different biotopes, occupied by L. naticoides after the initial phase of its spread in the upper section of this water body (downstream the city of Dubna), characterized by a complex hydrological regime. Approximate coordinates of the geographical center of the large settlement of L. naticoides are 56°53ʹN, 37°25ʹE. It is found that by 2019-2021 the average density of L. naticoides in this settlement reached a consistently high value of about 450 ind./m2. Judging by the variability of shell height in adult mature L. naticoides individuals, even within the same settlement, optimum habitat conditions for this mollusk differ significantly in different biotopes. In a comparative aspect, data from two main hydrobiological sampling locations are considered: in the open part of the reservoir and at the mouth of a large tributary - the Dubna River. It is shown that at both locations the species composition of trematodes in L. naticoides is similar and includes, in particular, parthenitae of Apophallus muehlingi (Jägerskiöld, 1899), Apophallus (= Rossicotrema ) donicus (Skrjabin et Lindtrop, 1919), Parasymphylodora markewitschi Kulakowskaja, 1947, Nicolla skrjabini (Iwanitzky, 1928). However, Sanguinicola volgensis (Razin, 1929) parthenitae, dominant in L. naticoides in the open part of the reservoir, is not found in the sample of mollusks from the mouth of the Dubna River. As compared to the sampling site in the open part of the reservoir, at the mouth of the Dubna River the level of infection with parthenitae of other species is significantly lower: N. skrjabini and P. markewitschi - 7 times, Apophallus spp. - 8 times, Xiphidiocercaria sp. - 13 times. The ratio of males to females among mature individuals of L. naticoides turns out to be close to 1:1, which is usual for many freshwater mollusks. In general, the high occurrence (the infection prevalence - the proportion of infected individuals in the host sample P±SE, %) in the open part of the reservoir indicates the presence of prerequisites for serious outbreaks of helminthoses: Xiphidiocercaria sp. (9.16±2.52%), Apophallus spp. (11.45±2.78%), P. markewitschi (7.63±2.32%), N. skrjabini (7.63±2.32%), S. volgensis (63.36±4.21%). At the same time, according to the data obtained, further spread of L. naticoides in some tributaries of reservoirs in the Upper Volga basin may not have such serious parasitological consequences.","PeriodicalId":44218,"journal":{"name":"Russian Journal of Biological Invasions","volume":"5 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75574436","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 content of trace elements in the organs and tissues of pink salmon introduced in the Euro-Arctic waters of Russia was compared to those of the pink salmon from its natural range, which returned to spawn in the rivers of the Sakhalin and Iturup Islands in 2016-2018. It has been established that concentrations of Zn, Cu and Ni noticeably predominate in all organs and tissues of introduced pink salmon, whereas Pb and Cd - in the Sea of Okhotsk pink salmon. Obviously, the differences in the microelement composition in fish are caused by environmental conditions. In the Barents Sea, they are formed under the influence of the Gulf Stream, as well as the anthropogenic impact of the Kola Peninsula, which is characterized by the extraction, processing and smelting of a number of metals, primarily Ni and Cu, as well as Zn. In the Sakhalin-Kuril basin, the specificity of the environment and the microelement composition of salmon are due to the influence of natural factors - volcanism and upwellings. Herds of pink salmon during feeding and migration in the Pacific Ocean cross a high-nutrient and at the same time geochemically impact natural zone formed by the Kuril Ridge and the Kuril-Kamchatka depression, which supplies chemical elements to surface waters. Here, the concentration of Pb is most markedly increased in fish. The development of the introduced pink salmon in the new area is facilitated by the recent increase in temperature in the waters of the North Atlantic, so the amount of fish production in it will increase. The mastering of pink salmon in new feeding places sets before scientists the task of monitoring the dynamics of its abundance, taking adequate measures for fishery regulation and fish quality control.","PeriodicalId":44218,"journal":{"name":"Russian Journal of Biological Invasions","volume":"5 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81389350","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}
