In Prague-Miškovice, a cemetery of the Únětice culture (UC) with a total of 44 graves was excavated between 1999 und 2001. The C14 dates range across the entire course of Central Europe’s Early Bronze Age – from the proto-Únětice phase to the “post-classical” phase of the UC. The high point of the mortuary activities occurred between 2000 and 1750...

Since the last comprehensive overview of the Czech and Slovak mollusc fauna, released in 2013, several records of species new for the countries or particular regions have appeared. In this paper, we summarize all such records and news collected in 2015-2019, including those affecting nomenclature and the national Check-lists made in 2013 and 2014....

A large karst doline at section Hrastje – Lešnica in the Dolenjska region (SE Slovenia) was uncovered during the construction of Slovene highway No. A2. Its fill consists of brownish-yellow clay to silt with plant remains and ferrugineous coatings after root casts and gastropods (paleosol horizon) in the bottom, and overlying thick lacustrine lamin...

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 unpublishe...

The new zoological exposition of the National Museum will be installed in eight exhibition halls on the second floor of the Historical Building. The exposition has the preliminary title Evolution and thematically, it will follow several significant evolutionary events, which enabled animals to occupy Earth. The first two exhibition halls will be de...

Vertigo lilljeborgi (Westerlund, 1871) is one of the rarest terrestrial snail species in temperate mainland Europe, where it is traditionally considered a glacial relict. This contrasts with its occurrence in northern Europe where it is a widespread species. This species prefers constantly wet habitats that are neutral to slightly acidic and avoids...

The current version of the check-list follows Horsák et al. (2013) with up-to-date modifications supplemented with a reference. Distribution map for each species was constructed based on published data and our knowledge based on unpublished records. So far 251 species of molluscs, including 223 species of gastropods (51 aquatic and 172 terrestrial)...

Due to the recent mapping and study of soil micro-morphology of the New brickyard at Horky nad Jizerou we were able to revise the sequence documented in the 1950s and 1960s in the Old brickyard. Sediments from Horky nad Jizerou document the evolution of loess sedimentation from at least MIS 15 to the pleniglacial of last glaciation (MIS 2). The dev...

Snail Cepaea vindobonensis (C. Pfeiffer, 1828) was recorded at two isolated localities in Marienbad and close to the village of Štítary in the foothills of the Český les Mts. (West Bohemia). While only a single specimen was recorded along a blind railway line near the railway station in Marienbad, the locality by Štítary hosts a rich viable populat...

Vertigo lilljeborgi is one of few European land snail species which are restricted to minerally poor habitats. It typically inhabits wet sedge marches and groundwater-fed fens with the occurrence of Sphagnum mosses. In Central Europe, the species re­presents a rare glacial relict, distributed mainly in the boreal zone of Europe and at seve­ral isol...

A tiny terrestrial snail Vertigo geyeri is an example of a typical late-glacial relict in the central Europe. It inhabits exclusively treeless fens and is highly endangered in most of its area and internationally protected. So far, only three recent and highly isolated populations have been found in the Czech Republic. The first one, a small calcar...

Pupilla pratensis (Clessin, 1871) was recently confirmed as a distinct species based on morphological, ecological and molecular evidence. The main purpose of this study is to publish the first reliable data on the occurrence of P. pratensis in the Czech Republic and Slovakia. The second goal is to analyse conchometry of P. pratensis, P. muscorum (L...

We document the first occurrence of the Kentish Snail Monacha cantiana (Montagu, 1803) from Prague, Czech Republic. During autumn 2009, an abundant population of M. cantiana was found at sites with suitable vegetation and microclimatic conditions, predominantly composed of grassy vegetation cover. It is expected that this species will continue to sp...

Based on over 3,500 dry shells and alcohol-preserved specimens from 77 localities, new records of 12 species (Truncatellina callicratis (Scacchi), T. himalayana (Benson), Boysia boysii (L. Pfeiffer), Vertigo antivertigo (Draparnaud), V. pseudosubstriata Ložek, Gastrocopta avanica (Benson), G. huttoniana (Benson), G. klunzingeri (Jickeli), Pupilla m...

Altogether, 106 sites were explored in the Žďárské vrchy Mts. during the years 1996-2006 and 101 species were found.

The aims of this study were to analyse whether land snail assemblage patterns reflect the gradient of calcium content on a very small scale within a site. We chose two sites differing in their calcium richness and source of the calcium. The "Tufa site" had abundant tufa in the soil, while the "Boulder site" was on chemically inert chert bedrock whe...

Sunken “hut” from the Middle Eneolithic in Prague 9 - Miškovice. Results of archaeological and palaeoecological analyses. The hut has a regular ground-plan (3.92 x 3.64 m) and simple as well as double rows of post-holes along the walls; it was studied in 2004. It represents a distinct architectural type of the Řivnáč culture. Roughly 1/3 of the hut...

A detailed molluscan succession from Holocene calcareous tufa deposits at the Kotyz Ridge and in the Cisarska Gorge in the Czech Karst provides the most complete record from central Bohemia. The succession has been reconstructed from three profiles and chronology provided by AMS radiocarbon dating of charcoal and dating of carbonate by the U-series...

120 mollusc species (50% of the Czech Republic mollusc fauna) were recorded from the Rychlebské Hory (Czech Republic, Silesia), as a result of the recent malacological research of 33 sites, combined with earlier published and unpublished data. The most diverse communities were those of forest valleys and old limestone quarries. New isolated sites o...

Data about recent molluscan fauna in the central part of the Český Les Mts. - Kateřinská Kotlina and the northern part of Čerchovský Les (Western Bohemia), with additional data from the phytogeographic district of Tachovská Brázda and Plzeňská Pahorkatina, are given. Altogether 84 species (73 species of Gastropoda - 14 aquatic and 59 terrestrial; 1...

Data about recent molluscan fauna in the northern part of the Český Les Mts. (= Oberpfalzer Wald in German), Western Bohemia, are given. Altogether 88 species (81 species of Gastropoda - 11 aquatic and 70 terrestrial; 7 species of Bivalvia) were recorded at 29 selected localities. The terrestrial molluscan fauna is dominated by woodland communities...

Malacological records from the past 100 years permit a synthesis of distribution, ecology and sociology of two Clausiliid species Macrogastra badia and Laciniaria plicata, very rare snails for the area of the Bohemian Forest. Alpine element Macrogastra badia is recognized from three interindependent islets in the area of Královský Hvozd, the wester...

The malacozoological investigation from the territory of Chodská Úhlava Valley near Svatá Kateřina Village in the northwestern part of the Šumava Protected Landscape Area has been performed. Very interesting and from the zoogeographical point of view also eminent, the new find of westeuropean species of the slug Arion intermedius Normand, 1852 has...
