Study of the European green lizard, Lacerta viridis, and ecologically interconnected reptile species in the Czech Republic
Chmelař, Jan ; Rehák, Ivan (advisor) ; Vojar, Jiří (referee) ; Moravec, Jiří (referee)
The European green lizard, Lacerta viridis (Laurenti, 1768), is protected in the Czech Republic as critically endangered. Its distribution in the Bohemia region is restricted to small isolated local populations which are located beyond the northern border of continuous range of the species and are closely related to very specific biotopes. We analysed the distribution of the species both on a national and microhabitat scale and created a predictive model of the species distribution. The most relevant factors influencing the species distribution in the Czech Republic were: annual precipitation, terrain slope, average temperature of the warmest quarter and precipitation in the coldest quarter. On the microhabitat level, individuals selected their immediate vicinity with respect to elevated stones/tree stumps, shelter availability and a proximity to shrubs. Places with high percentage of grass and high vegetation were not preferred. Furthermore, we analysed distribution of selected reptile species ecologically interconnected with Lacerta viridis and identified their preferred habitats. We selected the dice snake, Natrix tessellata, the sand lizard, Lacerta agilis and the smooth snake, Coronella austriaca. All created models are compatible with published data and are applicable in both theory 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...

A quantitative analysis of the state of knowledge of European lizards of the genus \kur{Podarcis}
ŠINDELÁŘOVÁ, Monika
This thesis presents the analysis of the state of knowledge of European lizards of the genus Podarcis. It is the most numerous species of the genus Podarcis of the family Lacertidae in Europe and it belongs to the most important representative of the Mediterranean herpetofauna. The aim of this thesis was to make a quantitative analysis of publication activities, analysis of topics and assessment of context biological properties of a number of publications. The data was obtained from a literary database ?Web of Science? and ?Google Scholar?. The number of publications in each year over the period was relatively stable. The relationship of dependence between size area and number of publications for each species affected the four most dominant species and this relationship does not exist for the species with small range. More endangered species had a small number of publications. Most publications were in the field of ecology.
