Contributions to the taxonomy, biogeography, ecology and pathogens of parasites (Diptera, Acari) of Old World bats
Ševčík, Martin ; Benda, Petr (advisor) ; Stanko, Michal (referee) ; Bartonička, Tomáš (referee)
The dissertation thesis presents contributions solving several faunistic, biogeographical, taxonomic, and phylogenetic problems of selected groups of bat parasites together with surveys of potential pathogens in some representatives of these parasitic groups linked to the bats of the Old World. In the first part of the thesis, the taxonomy of prostigmata mites - chiggers (Trombiculidae) - coming from Eurasia and Africa is elaborated. Results of a detailed morphological and morphometric study are the descriptions of five new taxa belonging to four genera: Chiroptella, Grandjeana, Rudnicula, and Trombicula. At the same time, the results revise the differentiation within the group Trombicula sensu stricto, summarize the findings of species of individual genera and correct the inclusions of the originally described species within individual genera, with the final output of creating identification keys to the genera. The first sketch of the results of the study of the relations between chiggers and bats is included in this section, representing the description of the specific links among individual segments of both groups. In addition, there are studies presenting new findings and morphometric examinations of velvet mite nymphs collected from bats in Indonesia, as well as morphometric data and...

Diversity and phylogeny of the lacertid lizards (Lacertidae) with emphasis on the tribe Eremiadini
Hlaváč, Denis ; Šmíd, Jiří (advisor) ; Chmelař, Jan (referee)
The family Lacertidae (lizards) belongs to the class Reptilia (reptiles) and the order Squamata (scaly reptiles). This family consists of two subfamilies, Lacertinae and Gallotinae, which are diversified into 45 genera and approximately 368 species. The subfamily Lacertinae is divided into two tribes, namely the tribus Eremiadini and Lacertini. The tribe Lacertini can be further divided into two clades: the Ethiopian and the Saharan-Eurasian clade. The subfamily Lacertinae, with approximately 354 species, is much larger than the subfamily Gallotinae, which consists of only 14 species. From the subfamily Lacertinae, the larger tribus Eremiadini is formed by 215 species classified in 22 genera. Representatives of this family can be found in Europe, Africa and Asia, but the center of origin is Europe. They belong to the dominant species of herpetofauna in Europe. The Eremiadini tribe separated from the rest of the Lacertidae family in the past and migrated to Africa, where it diversified into its present form. Currently, the diversity of the Eremiadini tribe is concentrated in Africa, but a large number of species also occur in Asia. The body is small to medium in size, which usually does not exceed 90 mm without the tail. The body shape is slender and the tail is relatively long compared to the body...
