Passive transport is an important way of spreading to new localities for slow-moving animals such as snails. Such modes of transport, often mentioned in the literature, include zoochoria or various human means of transportation. Watercourses are neglected in this regard, although they have been previously discussed as river corridors and proven rou...

By the standards of Prague, its south-eastern part represents a less diversified part of the city in terms of relief and geological composition. The present article describes the development of terrestrial mollusc fauna since the beginning of explorations of this area in the 1940s and a comparison with the current in-depth exploration. Currently, 8...

This paper presents important faunistic records conducted in the Czech and Slovak Republics during 2023. We also include records generated before 2023, which have yet to be published, mainly because their correct identification was unavailable earlier. In a separate section we present records of unintentionally introduced species, reported for the...

Recent zonal steppes of Eastern Europe and South-West Asia have their origin in the glacial steppe with its specific continental climate. The westernmost edge of the steppe belt in Central Europe has been climatically shifted from a continental course during the Last Glacial to a rather oceanic one during the Holocene. Steppe enclaves could survive...

This paper presents important faunistic records obtained from the territory of the Czech and Slovak Republics in 2022. Two new non-native species, Lauria cylindracea and Mieniplotia scabra, were recorded indoors, and also two new non-native species Cochlicella acuta and Testacella haliotidea were found outdoors in the Czech Republic. New occurrence...

The Špraněk NNR, as a prominent part of the Javoříčko Karst, has long been a focus of malacological research. In this study, we have assembled all the information on the mollusc fauna regarding this area by compiling literature data, records from the Natural History Museum in Prague, and data from our own field research. Since the end of the 19th c...

Since 1994 there has been regular monitoring of selected groups of animals in the still active Čertovy schody quarry in the Bohemian Karst, carried out by the staff of the National Museum, Prague, with the support of the quarry operator. The most continuous results were collected in the case of arachnids and molluscs, which are the subject of this...

This paper presents the most interesting findings from inventory surveys of small-scale protected areas in the Český les PLA from 2020 and 2021. The total number of mollusc species in the Český les has increased by two wetland species, Vertigo angustior and V. antivertigo. Several localities have been added to the single site of Nesovitrea petronel...

The Troja hills and slopes are located on the right bank of the Vltava River on the northern periphery of Prague. The mollusc fauna of certain parts of the territory has been regularly observed by Vojen Ložek since 1987. In 2021–2022 these parts were revised together with other sites in the Drahaň – Troja Natural Park. At 63 localities, 65 mollusc...

The carnivorous semi-slug Testacella haliotidea (Gastropoda, Pulmonata, Testacellidae) was recorded for the first time in Czechia, Prague. One adult specimen was found in the garden, probably originating from seedlings in the horticulture centre. Other findings about this species in Czechia are expected.

Hrnčířské louky NM in the southeast of Prague protects a pond system surrounded by wet meadows. Until now, only sparse data about mollusc fauna were available. In 2021, 28 snail species (26 land snails, two aquatic) were recorded during the land snail inventory. Together with older sampling that also focused on aquatic species, 47 mollusc species a...

Mollusc fauna of the Prokopské údolí Nature Reserve in Prague (Czech Republic) has been revised. The current research follows up on the monitoring that took place there at five-year intervals in the years 1984–2009. In the 1980s, 43 land snail and seven aquatic species were recorded, while in 2020 the list included 56 land snail and three aquatic s...

Mollusc fauna of three protected areas in the capital of the Czech Republic, Prague, was revised after 25 years (Hvězda Game Reserve, Petřín) or studied for the first time (Vyšehrad). In total, 56 molluscs species were found and the survival of endangered species Vertigo angustior and Nesovitrea petronella in the Hvězda Game Reserve was verified. G...

River floodplains of Czech rivers serve as refugia to woodland or hydrophilous gastropods, in current intensively agriculturally utilised, urbanised and largely fragmented landscape. This habitat often form one of the last refuge and replace the natural habitat of these species. River floodplains also represent linear bio-corridors in landscape and...

A total of 95 species of molluscs were recorded in the Kačák brook valley (Central Bohemia, Czech Republic), in its upper and middle part. Most of the terrestrial survey was conducted in the woody part of the studied area, therefore woodland gastropods represent 31% of the total species number, followed by generalists, hygrophilous and steppe speci...

This paper brings findings of recent malacological research (2013) and earlier mostly unpublished data about malacofauna of the Karlštejn National Nature Reserve (abbreviated as NNR) (Czech Republic, Central Bohemia, Bohemian Karst Protected Landscape Area). A total of 89 mollusc species (76 terrestrial snails, 5 freshwater snails, 8 bivalves) were...

Exotic invasive plants are known to decrease mollusc species richness and also abundances of many snail species. However, there is not much evidence on how invasive plants influence snail trophic behaviour. In this study, food preferences of alluvial land snails for invasive plants were studied. Two snail species (Succinea putris and Urticicola umb...

The recent mollusc assemblages of the Vltava River, the longest river in the Czech Republic (430 km), and its valley were studied (South and Central Bohemia). Altogether, 162 species of terrestrial and freshwater molluscs representing 65% of the total Czech malacofauna, were recorded at 532 sites studied between 1940 and 2013. Considering high spec...
