World travellers: phylogeny and biogeography of the butterfly genus Leptotes (Lepidoptera: Lycaenidae)
 PAPP MAREŠOVÁ, Jana
In this thesis, we investigated phylogenetic and biogeographical relationships of neglected butterflies of the subtribe Leptotina (Lepidoptera: Lycaenidae), widely distributed in tropical and subtropical areas around the world. We used both mitochondrial and nuclear markers and different molecular analyses to resolve relationships within the subtribe. We also focused on diversification times and biogeographical patterns of Old World taxa and detailed phylogeography of the most widespread species, Leptotes pirithous.

Wingless/Notch crosstalk in Drosophila melanogaster
 Hajšmanová, Hana ; Mašek, Jan (advisor) ; Macůrková, Marie (referee)
Fundamental for the existence of multicellular organisms is the presence signalling pathways, complex biochemical cascades, allowing reciprocal communication amongst the cells. Both Notch and Wnt pathways are crucial for embryonic development and their deregulation leads to many severe diseases. Decades of research, largely based on model organism D. melanogaster, showed that components of these pathways do not function strictly separately but on contrary interact with each other (crosstalk). This phenomenon is explored only to a lesser extent in mammals. The aim of this thesis is to recapitulate existing findings of Wnt/ Notch crosstalk in D. melanogaster and outline where crosstalk could play a role in mammals.
