The first record of Corbicula fluminea (O. F. Müller, 1774) in Moravia (SE Czech Republic)

Corbicula fluminea, an invasive bivalve of SE Asian origin, has been recorded in the Morava River in Moravia (SE Czech Republic, Danube River basin) for the first time in 2018

Komentovaný seznam měkkýšů zjištěných ve volné přírodě České a Slovenské republiky

In this paper we provide a new list of all the mollusc species recorded outdoors in the Czech and Slovak Republics. This work is a supplement of the Ložek’s key on molluscs of the former Czechoslovakia. For the species recorded after the publishing of the book, publications of their first records in the Czech and Slovak Republics are given. Species which are either not included in this Ložek’s book or whose current taxonomical status highly differs from that published in the book are supplied with Czech commentaries, photographs of their shells or bodies, and drawings of important identification characters. This material is aimed at Czech and Slovak malacologists to provide information, missing or scattered in the literature, on currently known mollusc fauna of the Czech and Slovak Republics. The Ložek’s book and this supplement should provide necessary information on identification, ecology and also distribution of all mollusc species currently known from the Czech and Slovak Republics. If the species names used in this paper differ from the ones used in the Ložek’s book, we mention both. So far 247 species of molluscs, including 219 species of gastropods (50 aquatic and 169 terrestrial) and 28 species of bivalves, have been found outdoors in the Czech Republic. The fauna of Slovakia comprises 247 species, including 219 gastropods (51 aquatic and 168 terrestrial) and 28 bivalves. Altogether 282 species occur in the Czech Republic and Slovakia, 212 of them being common to both countries

Radiation in Bythinella Moquin-Tandon,1856 (Mollusca : Gastropoda : Rissooidea) in the Balkans

61 sequences of cytochrome oxidase subunit 1 (COI), 570 bp long, from Central Europe (8), Slovenia (2), and from the Balkans (51: 6 from, Romania, 15 from Greece, 15 from Bulgaria, 6 from Serbia, and 9 from Montenegro), 33 of them new, together with 61 sequences of the ribosomal 18S, 450 bp long, all of them new, were analysed to infer the pattern of radiation of Bythinella in the Balkans. Thirty two nominal taxa of Bythinella (22 nominal species: B. austriaca, B. calimanica, B. charpentieri, B. compressa, B. dacica, B. dispersa, B. grossui, B. hansboetersi, B. luteola, B. micherdzinskii, B. molcsanyi, B. nonveilleri, B. pannonica, B. pesterica, B. radomani, B. rhodopensis, B. robiciana, B. schmidti, B. slaveyae, B. srednogorica, B. taraensis and B. viseuiana; one nominal subspecies: B. austriaca ehrmanni; and nine Greek species not yet described) were included, represented mostly by paratypes or at least topotypes, collected at 31 Balkan localities. The phylogeny, inferred on the combined data set with the ML approach, showed two large clades, although they were weakly supported. One of them comprised the Romanian and Montenegro populations, and one Serbian population, the other (less genetically diversified) consisted of one Serbian and all the Bulgarian/Greek populations. The origin of those two clades was dated, with the external data, to be more than 4.341±0753 MYA old, thus its origin was assigned to isolation by the Dacic Basin (part of Paratethys). All the Bulgarian populations presumably belong to one species, which may be assigned to the recent recolonisation of this territory from the south

Měkkýši Hostýnských vrchů

This study deals with the molluscan fauna of the Hostýnské vrchy Hills (Central Moravia, Czech Republic). The main goal was to make a systematic inventory of the molluscan fauna in this area. Snails were collected in September 2010 by hand picking and litter sampling at selected sites. Final database was pooled with earlier published and unpublished data. In total, 85 terrestrial and 20 freshwater mollusc species were recorded at 56 study sites across the area during 2000–2010. Terrestrial snails Monachoides incarnatus, Punctum pygmaeum, Vitrina pellucida, and freshwater molluscs Pisidium casertanum, and Radix labiata were the most frequently recorded species. The land snails Daudebardia brevipes, Eucobresia nivalis, Vitrea transsylvanica, and Chondrula tridens are notable species from the local viewpoint. The clausilid Vestia ranojevici moravica, an endemic subspecies that colonized some regions of Moravia during the Holocene climatic optimum, is an iconic mollusc species in the area, deserving high conservation priority

Malacological news from the Czech and Slovak Republics in 2023

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 first time for the countries from greenhouses (Dryachloa dauca and Guppya gundlachii). The first outdoor colony of Melanoides tuberculata was found in a stream artificially heated by wastewater from the Dukovany nuclear power plant and Planorbella duryi found in a brook with thermal water flowing from the Sliač spa. Records of native species include findings of protected and rare species (e.g., Aplexa hypnorum, Ladislavella occulta, Daudebardia brevipes, and Theodoxus danubialis), but also still poorly known species (Ampullaceana lagotis and Pyramidula saxatilis). During 2023, many new records were made for non-native and currently spreading species as for example Clathrocaspia knipowitschii, Corbicula fluminea, Hygromia cinctella, Krynickillus melanocephalus, Sinanodonta woodiana, and Tandonia kusceri

Fenomén prameništních slatinišť a malakologické konsekvence

The objective of this paper is to (a) summarize the results of malacological investigations of the West Carpathian treeless spring fens and (b) show how unique sites these fens are. The mollusc communities were studied from several ecological points of view such as: response to the poor-rich mineral gradient, calcicole-calcifuge behaviour, geographical distribution, and historical development. The published or prepared articles concerning above-mentioned topics are cited in the text
