Echinoids, their evolution and response to the Cretaceous paleoenvironmental events
Hedánková, Karolína ; Košťák, Martin (advisor) ; Nohejlová, Martina (referee)
The bachelor thesis briefly summarizes knowledges about the evolution of sea urchins (Echinoidea; Echinodermata) with a focus on the successful order Spatangoida and their diversification in the dynamic Mesozoic environment. Attention is paid in particular to significant palaeoceanic changes, such as anoxic events (OAE = Oceanic Anoxic Event) and extinctions. Responses to OAE1-OAE3, as well as the last mass extinction (within the "Big Five") at the Cretaceous-Paleogene (K-Pg) boundary, are briefly discussed. Sea urchins, as an important part of benthic communities, prove to be a suitable model group not only for understanding the dynamics of evolution, but also successful strategies for surviving crisis events and new adaptations. Key words: Mesozoic, echinoids, evolution, events

Current view on the biology of theropod dinosaurs
Honskus, Adam ; Teodoridis, Vasilis (advisor) ; Řezníček, Jan (referee)
This bachelor thesis hes summarised available data from morphology, anatomy, ecology, ethology, ontogeny and phylogeny of theropod representatives of the clade Dinosauria that are based on the recent results deriving from the application of modern scientific methods and technologies. Main methods are laser scanning, computed tomography, electron microscope analysis and virtual and physical model reconstruction. Application of these results have changed radically historical and dogmatic point of view on this fascinating group of dinosaurs that had ruled on the Earth for more than 150-million years.
