For this, adult snails collected at 33 sites from 2011 to 2022 were studied anatomically. We found Monacha fruticola in two sites (Lviv, Briukhovychi), two cryptic species M. cartusiana and M. claustralis in 4 sites (Lviv, Yampil), only M. claustralis in one site in Lviv, and only M. cartusiana (single individuals or populations) in the remaining 26 cases. The distal genitalia of M. claustralis from new discoveries in and near Lviv, the variability of the vagina shape in M. cartusiana and M. claustralis from the studied area are shown. The possible role of private cars in the rapid spread of M. cartusiana in the study area is discussed. The chronology of registration of M. cartusiana in Western Ukraine is shown in a tabular format. A significant expansion of the range of M. cartusiana in Ukraine was noted, although almost until the very end of the 20th century this species was mentioned only for the southern part of the country, including Crimea.","PeriodicalId":309868,"journal":{"name":"Folia Malacologica","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121916827","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}

They possess two modes of respiration: pulmonary and surface (diffusive). The gas exchange in these snails is connected to the presence of the respiratory pigment hemoglobin in their internal liquid medium (hemolymph), which transports oxygen in their tissues and organs, and carbon dioxide to the lungs. We studied the features of impact of three mineral fertilizers widespread in Ukraine (nitrate, potassium and phosphate) used in concentrations measured in MPC 0.01 mg/L (0.5, 1, 2, 3) on the indexes of pulmonary and surface diffusive respiration in both P. corneus s. lato allospecies. Exposure of experimental individuals to 0.5 MPC-solutions of mentioned fertilizers does not affect them. The increase of toxicant concentration up to 2 MPC, however, is followed by an increase in respiratory activity (p≤0.05–0.001), but beyond that up to 3 MPC induces a significant decline (p≤0.001). Considered individually, the examined mineral fertilizers presented the following order by their impact on great ramshorns: nitrate > potassium > phosphate. The “eastern” allospecies appeared to be more sensitive and less durable for all aforementioned pollutants by both lung and direct diffusive respiration, compared to the “western” allospecies (p≤0.05–0.001).","PeriodicalId":309868,"journal":{"name":"Folia Malacologica","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134205406","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}
