Species composition of land molluscs of Zaporozhye region and anthropochory influence on it

Abstract

37 species of the land molluscs were identified in the material collected in 2002-2017, many being earlier unknown from Zaporozhye region. In total 39 species of molluscs can be considered as reliably recorded from this region. The presence of some species is the result of anthropochory. This concerns first of all those land snails which have spread from the Crimea: Brephulopsis bidens, B. cylindrica, Phenacolimax annularis, Oxychilus deilus, Monacha fruticola, Xeropicta derbentina, X. krynickii, Eobania vermiculata, Helix lucorum. One species (Xerolenta obvia) was introduced to Zaporozhye region from the western part of Ukraine. The data obtained made it possible to clarify the current distribution of Helicopsis retowskii and Chondrula tridens martynovi over the territory of Ukraine.

Three introduced Monacha species (Gastropoda: Hygromiidae) in and near Lviv with remarks on M. cartusiana spreading in Ukraine and its Western part

“…However, even now M. cartusiana occurs mainly in anthropogenic rather than natural coastal habitats of the southern Crimea (balaShov & marKova 2023), which may indicate that this species is alien here. According to published data (Gural-Sverlova et al 2018, GeNSytSKyi 2021, in the eastern Zaporizhzhia region (Southern Ukraine), which balaShov & marKova (2023: fig. 2) include in the zone of "continuous distribution" of M. cartusiana, this species is found now sporadically and much less frequently than M. fruticola, which was brought here by people from the Crimea and became one of the most abundant species of land molluscs.…”

Further and Further East: Steppe Land Snail, Xerolenta obvia (Gastropoda, Geomitridae), Expands its Range in Ukraine

“…Th e records of X. obvia in Ukraine made in two diff erent periods of time were analyzed and graphically presented on maps (fi g. 2): 1) from the second half of the 19th century, when a purposeful study of land mollusks began in the areas of present Lviv, Ternopil and Ivano-Frankivsk Regions in the west of Ukraine (Bąkowski, 1884), until the middle of the 20th century; 2) from the end of the 20th century to the present. Th e choice of the second time period was due to the fact that in this time the cases of registration of introduced species of land mollusks in diff erent parts of Ukraine became noticeably more frequent (Gural-Sverlova et al, 2018;Gural-Sverlova-Gural & Gural, 2021: table 2;Sverlova et al, 2006), some species were fi rst recorded in Ukraine and/or rapidly expanded their ranges on its territory Gural-Sverlova & Gural, 2022;. We considered it inappropriate to divide the fi rst period into shorter time intervals due to, in general, a small amount of data.…”

“…forest-steppe zone in the central part of the country (Balashov, 2010;Balashov & Baidashnikov, 2012;Balashov et al, 2018 c) and in the Transcarpathian Lowland (Gural-Sverlova & Gural, 2017). Th e natural distribution of another species, Xerolenta obvia (Menke, 1828) in Ukraine is limited exclusively to the western part of the country, although its fi ndings are already known in Zhytomyr (Gural-Sverlova & Gural, 2020), Kyiv (Tappert et al, 2001) and in the Zaporizhzhia Region (Gural-Sverlova et al, 2018). In the Donetsk Region, X. obvia was recorded for the fi rst time.…”

Land snails <i>Brephulopsis cylindrica </i>and <i>Xeropicta derbentina </i>(Gastropoda: Stylommatophora): case study of invasive species distribution modelling

“…Actual localities, i.e., places where X. derbentina and B. cylindrica had been reported, came from three sources: field collection data of the authors (29 sites for X. derbentina and 23 for B. cylindrica), published records (59 and 45 sites) [Balashov, Baidashnikov 2012;Balashov et al, 2018a;Balashov et al, 2018b;Rabchuk, Zemoglyadchuk 2011;Gural-Sverlova, Gural 2007;Vitchalkovskaya 2008;Kramarenko, Sverlova 2001;Gural-Sverlova, Gural 2017;Gural-Sverlova et al, 2018;Kramarenko, Dovgal 2014;Kovalenko 2019;Zhukov et al, 2019;], and data in the GBIF database that also include iNaturalist data (gbif.org) (62 and 83 sites); all localities are shown in Fig. 1, with data in Supplementary Material Tables 1-4.…”
