Genus Apodemus (Mammalia: Rodentia) in the Quaternary fossil record of Central Europe.
Knitlová, Markéta
Wood mice of the genus Apodemus rank among the most common extant mammals throughout Europe. A history of its species and their distributional ranges is to be looked upon as a serious topic relevant also for general concepts on current setting of European biotic diversity. Nevertheless, despite several phylogeographic studies on that subject and a rich fossil record of the genus, many details of that issue remains only very poorly comprehended. This state is essentially caused by enormous complications with phenotype discrimination of individual species, their extensive variation and broad between-species overlaps in all phenotype traits. The present project was intended to establish the techniques enabling reliable species identification applicable to fragmentary fossil materials and to use them for retrieving information on range dynamics and phylogenetic history of individual species during the Quaternary past. It begun with detailed morphometric analyses of extant populations, using the characters available in fossils, and with establishing a concept of alternative parataxonomic classification covering the complete phenotype span of the genus. The respective techniques were applied onto an extensive set of well-dated records from the Late Pleistocene-Holocene sedimentary series from diverse...

Holocene development of European open landscape based on mollusc succession.
Nádvorníková, Lenka ; Juřičková, Lucie (advisor) ; Rozkošná Knitlová, Markéta (referee)
Steppe was the most significant biome of glacial periods, but after deglaciation, very hostile condition to maintain the steppe came up. As the youngest interglacial, Holocene is the first epoch in which human influence on nature can be observed. This is evidenced by mollusc successions from previous interglacials, in which climatic optimum provide records of fully developed forest communities, in the same site, where mosaic of open habitats and forests occur in Holocene successions. It can therefore be assumed that the Holocene development of the landscape has been affected by man, which enabled continual occurence of open habitats. Key words: steppe, molluscs, Holocene, Europe, fossils
