MÜLLER, 1774) (GASTROPODA: PULMONATA: HYGROMIIDAE) BECOMES MORE FREQUENT IN POLAND ANDRZEJ LESICKI1,EL¯BIETA KORALEWSKA-BATURA2 1Department of Cell Biology, 2Department of General Zoology, Faculty of Biology, Adam Mickiewicz University, Umultowska 89, 61-614 Poznañ, Poland (e-mail: [email protected]) ABSTRACT: Monacha cartusiana (O. F. Müller, 1774) was found at new sites in Poland: in Janikowo near Inowroc³aw and in Poznañ. At the site in Poznañ, adult individuals were relatively large, as their shell width ranged from 14.5 to 19.7 mm. It must be emphasised that adult individuals of M. cartusiana with shell width of nearly 20 mm have not been reported so far. The new sites of this snail indicate that it has become a perma- nent component of the Polish fauna.

Its presence at the Lacu Roºu (Gyilkos-tó) area rep- resents the southeasternmost occurrence of the species. The only sample of P. lubomirski hitherto reported from Romania (leg. JICKELI in 1888 at Borsec Bai) seems to be lost from museum collections. The northern Carpathian distributional type is suggested for the species. The nomenclatural problem regarding the spelling of the specific name (i.e. lubomirskii or lubomirski) is discussed. The original, but less frequently used spelling (lubomirski) is suggested based on our understanding of the regulations of the ICZN.

Gural-Sverlova, N. V., Gural, R. I. — Two colonies of the land snail Monacha fruticola, whose native range is considered limited by the Crimea, were fi rst discovered in Western Ukraine, in Lviv City and in its immediate vicinity (Bryukhovichi settlement). Th ey are the northernmost records of this species, currently known. Th e present distribution of M. fruticola outside the Crimean peninsula is analyzed. Key words: terrestrial mollusks, anthropochory, invasive species, Ukraine. Introduction Th e native range of Monacha fruticola (Krynicki, 1833) is probably limited by the Crimean peninsula. Previously, Asia Minor was also considered part of it ( Schileyko, 1978). However, Hausdorf (2000) has showed that other species of Monacha Fitzinger, 1833 are distributed there. Known records of M. fruticola in southern Ukraine outside the Crimean peninsula (Schileyko, 1978; Korniushin, 1986; Kramarenko & Sverlova, 2001; Sverlova, 2006; Ryabseva, 2012; Gural-Sverlova et al., 2012; Balashov et al., 2013; Gural-Sverlova et al., 2018) are usually considered solely the result of anthropochory (Schileyko, 1978). Recently, a case of the introduction of this species by the human into Armenia was also described (Gural-Sverlova et al., 2017). Material and methods In 2018–2019, two colonies of M.

In Latvia, this species was first recorded in 1989 in Liepāja. Observations in recent years in Liepāja have shown that snails from their initial introduction sites on the railway have also spread to the sand dune habitats within the city limits. Given that there are no snails in dune habitats that are biologically equivalent to X. obvia, this species is considered to be potentially invasive. As the distribution trends of this species in Liepāja indicate a possible threat to dry habitats in natural areas, detailed study of the species was conducted for the population of this species located in Dobele. Monitoring was performed from May 26 to August 5, 2019, carrying out 11 surveys with one week interval using the capture and re-capture method. The maximum recorded distance travelled by of one snail was 29.7 m; the calculated minimum estimated population density was 170 individuals and the maximum was 2004 individuals. Key words: alien species, Dobele population, eastern heath snail, Helicella candicans, Helicella obvia, potentially invasive species.

  • Land Snails of Leicestershire and Rutland
    Land Snails of Leicestershire and Rutland Introduction There are 50 known species of land snail found in Leicestershire and Rutland (VC55) which represents about half of the 100 UK species. However molluscs are an under-recorded taxon group so it is possible that more species could be found and equally possible that a few may now be extinct in our two counties. There was a 20 year period of enthusiastic mollusc recording between 1967 and 1986, principally by museum staff, which account for the majority of species. Whilst records have increased again in the last three years thanks to NatureSpot, some species have not been recorded for over 30 years. All our land snails are in the class Gastropoda and the order Pulmonata. Whilst some of these species require damp habitats and are generally found near to aquatic habitats, they are all able to survive out of water. A number of species are largely restricted to calcareous habitats so are only found at a few sites. The sizes stated refer to the largest dimension of the shell typically found in adult specimens. There is much variation in many species and juveniles will of course be smaller. Note that the images are all greater than life size and not all the to the same scale. I have tried to display them at a sufficiently large scale so that the key features are visible. Always refer to the sizes given in the text. Status refers to abundance in Leicestershire and Rutland (VC55). However molluscs are generally under- recorded so our understanding of their distribution could easily change.

  • Carthusian Snail Monacha Cartusiana
    Michigan State University’s invasive species factsheets Carthusian snail Monacha cartusiana Previously detected in the Detroit area, the Carthusian snail has a high risk of re-invading Michigan. Since it can feed on a wide variety of plants, this exotic land snail potentially impacts various agricultural and horticultural commodities as well as native plant communities. Michigan risk maps for exotic plant pests. Other common name Helicid snail Systematic position Mollusca > Gastropoda > Hygromiidae > Monacha cartusiana (Müller) Global distribution Found in Europe, Mediterranean region. Carthusian snails. (Photo: F. Geller-Grimm, Wikimedia.org) Quarantine status: Small populations of this snail have been detected at rail yards in Detroit and Chicago (USDA- APHIS-PPQ). This snail is listed as a prohibited mollusk species by Michigan’s plant protection regulations (MDA 2009). Plant hosts A wide variety of live and dead plants (Taylor 1917). Biology The Carthusian snail is an air-breathing land snail. It inhabits sunny and dry bushes and grassy slopes, hedges and street sides in low altitudes (Anon.). After mating, adult snails deposit eggs in loose, damp soil. Although egg- laying extends over several mouths, most eggs are found in autumn (Chatfield 1968). During the day, the snail adheres to the stems of plants and grasses, or other suitable objects (Taylor 1917). Identification (Photo: L. R. Kolouch, Bugwood.org) Shell characteristics: round shell up to 15 mm in diameter; 5.5 to 6 whorls; shell white to pale brown in color, found in Michigan. somewhat solid and translucent; under magnification, minute hair on a part of shell surface may be visible. Economic and environmental significance to Michigan Management notes This snail feeds on a wide variety of plants, and may During the 2004 CAPS survey for exotic snails and cause damage on agricultural and horticultural crops slugs, inspections focused on habitats such as refuse as well as native plants.

Several factors play an important role in changes of the distribution of these species: ecological (climate change), ethological (passive dispersal potencial) and economic (increasing traffic as a vector of spreading). The spreading of M. cartusiana has a rapidly increasing trend. More than half sites in the Czech Republic were colonised by this species in 2000–2010. While the spread of C. nemoralis has been continuous during the last century, the rapid range extension was recorded in the last two decades. Key words: Cepaea nemoralis; Monacha cartusiana; passive dispersal; range extension; grid map; distribution trends Introduction The main goals of our study are to visualise and describe the spread of two non-indigenous species: the The European biota has experienced a substantial shift Mediterranean Monacha cartusiana (O.F.
