Ecology,ethology and variability of european green lizard Lacerta viridis in Natural reservation Tiché údolí
 Chmelař, Jan ; Rehák, Ivan (advisor) ; Moravec, Jiří (referee)
The European green lizard, Lacerta viridis, is in the Bohemia region stated as critically endangered species. Populations in this region are located beyond the northern border of continuous range of this species and are closely related to the "riverine phenomenon", and deeply engorged river valleys. The chosen locality in Tiché údolí is a subject to a long-term conservational management aimed to strengthen and maintain abundance of the local population. This management is a direct output of a previous study of this population performed in years 1995-1997. Main goal of the presented study is to compare current population characteristics with the older study. The locality has been visited 119 times in years from 2011 to 2014. The studied population now displays higher abundance and inhabits a larger area. The author also performed a spatial analysis of the places with presence of an observed individual in order to determine and evaluate significance of the chosen abiotic factors for habitat discrimination. The results indicate that positive discrimination is based on the presence of a rock debris and a hiding place. Strongest factors towards negative discrimination were high percentages of grass and high vegetation coverage. This study also contains and discusses ecological, ethological and...

Autecology of local population of European green lizard (\kur{Lacerta viridis}) in Český kras.
 BLAŽEK, David
European green lizard (Lacerta viridis) is critically endangered species. Bohemian populations are usually isolated and with lower degree of genetical variability, which gives them a higher degree of vulnerability. Isolated populations are interesting because animals often live there under ultimate possible life conditions for given species, usually in original environment. For the sake of an effective protection of the species morfological, ethological and ecological data are necessary, as well as comparisions between populations of this character, so we studied from this point of view given population of European green lizard and conclusions and comparisions were made.
