Geochronologic and Paleoclimatic Characterization of Quaternary Sediments in the Great Hungarian Plain

Abstract

ABSTRACT. We reconstructed the climate of the Great Hungarian Plain between the years, 7-32 ka BP using a malacothermometer method. The reconstruction is based on seven Gastropoda taxa, for which optimal temperature and tolerance ranges have been determined. The temporal scales of the malacofaunal levels were calibrated with radiocarbon data. We compared our paleotemperature values with the temperature values of existing climatic curves and found the same climatic periods.

The late pleistocene paleoenvironment and paleoclimate of the madaras section (South Hungary), based on preliminary records from mollusks

“…Fluctuations in the abundance and dominance values of individual paleoecological and biogeographical groups according to depth are depicted for each profile using charts and tables prepared with the help of the Psimpoll software package [24]. Climatic reconstructions were conducted on the Madaras fossils using the malacothermometer method [16,25,26,35], based on the recent biogeographic patterns of 11 dominant gastropod species from a composite malacofauna [16,26,35]. For the selected gastropod species, optimal climatic conditions were determined, along with the minimum and maximum temperature tolerances (i.e.…”

“…For the selected gastropod species, optimal climatic conditions were determined, along with the minimum and maximum temperature tolerances (i.e. the gastropods' activity range), based on meteorological station data [16,25,26,35]. The stratigraphic position of different sedimentological layers in the Madaras brickyard's loess wall were identified using the methods of Marković et al [27,28], but based on a local stratigraphic system.…”

Postglacial colonisation of western Central Europe by Polyommatus coridon (Poda 1761) (Lepidoptera: Lycaenidae): evidence from population genetics

“…DOI: 10.1038/sj/hdy/6800003 species can be studied by analysing pollen (eg, Huntley and Birks, 1983;Gliemeroth, 1995). For animals, sufficient remains only exist for some groups, such as beetles or terrestrial gastropods (eg, Coope, 1970Coope, , 1994Hertelendy et al, 1992); for the great majority of invertebrates, hardly any evidence of this kind is available.…”

First radiocarbon dated paleoecological data from the freshwater carbonates of the Danube-Tisza Interfluve

“…The mussel and snail shell fragments were retrieved from the monolith of the freshwater carbonate via multiple freeze -thawing. The shell fragments then were boiled in distilled water and cleaned with diluted H 2 O, before the analysis [24]. The physical parameters and experimentalsetup of radiocarbon measurements on mussel shells carbonates have been detailed previously [24].…”
