Article
The Western Carpathian Mountains have been attracting palaeoecologists for a long time, recently mainly to seek direct evidence of northern cryptic refugia in this region. We investigated a rich Holocene mollusc record in the White Carpathian Mountains, capturing a gradual development of forest malacofaunas under stable environmental conditions. To...
Article
This study investigates the effects of sample volume, resolution and accumulation time on the interpretation of a mollusc record from terrestrial deposits. We tested (i) if, and to what extent, small sample sizes impoverish the reconstructed mollusc species richness, and (ii) whether fine-resolution sampling is worth the effort. We analysed three m...
Article
Calcareous tufas are great archives of geochemical information for the reconstruction of past climate. Their importance increases in the regions where other proxies are rare, such as Western Carpathians. Here, we present the first whole-Holocene palaeoclimatic reconstruction for this region based on geochemical proxies. We analysed δ 18 O, δ 13 C...
Article
Western-Carpathian travertine fens developed on deep-circulation groundwater are highly localised and harbour unique communities that combine rare species of calcareous fens and salt marshes, with many species considered glacial or Early-Holocene relicts. Using a multi-proxy palaeoecological approach, we tested the assumption of naturalness and Hol...
Article
There is still not enough palaeoecological data from the southwestern part of the Western Carpathians, where mountain ridges steeply rise from the dry and warm Pannonian basin. The reason is a low availability of sites with sediments harbouring fossil remains. In the Považský Inovec Mts, two small protected calcareous wetlands occur in different ge...

Calcareous tufas are continental open-air carbonates that routinely host evidence of past environmental conditions via well-preserved faunal and floral assemblages. As they mostly comprise of calcite precipitated at ambient temperature, tufas are also suitable targets for geochemical research, especially concerning oxygen and carbon isotopes, and t...

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 distribution pattern of relict and specialised species in calcareous fens was revealed to be non-stochastic, with ancient fens harbouring more of these species than younger ones. This phenomenon could be caused by long-lasting in situ survivals over millennia, but direct palaeoecological evidence is lacking. We addressed the question whether at...

Project
This project covers the last 15.000 years and uses an innovative interconnection of local sequences, their spatial heterogeneity, reconstructions of regional macroclimate using independent abiotic (stable isotopes) and biotic proxies, modelling of past landscape patterns and testing their effect on recent diversity, and continental-scale comparisons. Geographically, the project is focused on the Western Carpathians as the major biogeographical interface within Europe, and Northern France as a reference region with a different refugial history. Fossils of terrestrial molluscs in calcareous deposits act as a principal proxy. Pollen, testate amoebae and plant macrofossils act as important proxies for validations of local developments, macroclimate reconstructions and spatial modelling of past landscape diversification.
