Evolution and biogeography of flea beetles (Coleoptera: Chrysomelidae: Galerucinae: Alticini)
 Damaška, Albert ; Fikáček, Martin (advisor) ; Skuhrovec, Jiří (referee)
Leaf beetles belong to most diverse groups of insects and the biggest diversity inside this group is among flea beetles. This work summarizes existing hypotheses about their relationships with other groups of leaf beetles (especially galerucines) and compares various hypotheses about their phylogenetic position and suprageneric systematics. I also rewiev known fossils of flea beeltes and discuss their systematic position and evolutionary or biogeographic significance. The success of flea beetles is likely caused among others by their specific characters, (e. g. their jumping ability), and also their ability to reach dozens of various strategies and ecological adaptations. I discuss both morphological and ecological specifics of flea beetles and especially, I focus on apparently marginal life strategies - terrestrial and moss inhabitance, because in these ecological niches, an interestingly big diversity of flea beetles is uncovered recently. Moss-inhabiting flea beetles are also a very interesting model for ecological, evolutionary and biogeographical studies, because of their high endemism and low dispersal abilities. I also discuss extant distribution of flea beetles in the work and I concern questions about the origins and dynamics of their distributional ranges. I propose theories on possible...
