Gigantism of Paleozoic insects and other arthropods
 Pecharová, Martina ; Prokop, Jakub (advisor) ; Knor, Stanislav (referee)
Gigantism of insects and other arthropods was rather common in Late Paleozoic. Hypothesis of the oxygen limitation is one the probable explanations caused the phenomenon. Carboniferous insect gigantism was probably directly caused by the higher level of atmospheric oxygen due to direct effectiveness on the tracheal system. Therefore the possibility to grow to large sizes is clearly dependent on the amount of available oxygen. Another fact supporting the hypothesis is the extinction or the change of the giant insect forms at the end of the Permian, when the level of atmospheric oxygen suddenly decreased. This thesis also describes the ecological relationships of the Late Paleozoic arthropods, which is clearly connected to the evolution of giant forms. Gigantism during this period was thus developed by the interplay of several factors related to the global elements cycles. Another part covers major groups and representatives of Palaeozoic gigantic insects and other arthropods. The final part is devoted to describing the physiological experiments related to this topic.
