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...

Mesophilous grassland butterflies of European interest under climate changes (Lycaena dispar, Lycaena helle, Phengaris nausithous, Phengaris teleius, Euphydryas aurinia)
Vrba, Pavel ; Faltýnek Fric, Zdeněk ; Rindoš, Michal ; Hájková, K. ; Konvička, Martin
Methodological material summarizing variants of the habitat conservation principles for butterflies inhabitting mesophilic and humid grasslands under various scenarios of climate change. The species of interest, protected by the EU Habitats Directive, are Euphydryas aurinia, Phengaris nausithous, Phengaris teleius, Lycaena dispar and Lycaena helle. It includes the predictions of suitable locations for spontaneous or assisted colonization.

Dry grassland butterflies of European interest under climate changes (Colias myrmidone, Parnassius apollo, Phengaris arion)
Faltýnek Fric, Zdeněk ; Konvička, Martin ; Rindoš, Michal ; Sucháčková Bartoňová, Alena ; Spitzer, Lukáš ; Vrba, Pavel
The methodology summarizes the principles of the habitat conservation of several butterflies - Phengaris arion, Parnassius apollo and Colias myrmidone, species specialized to dry grasslands, rock screes and similar habitats, under different scenarios of climate change. Maps of future climatically suitable habitats are included, together with an analysis of the possibilities of assisted colonization.

Endangered butterflies of lowland forests under climate change
Konvička, Martin ; Beneš, Jiří ; Číp, D. ; Sobík, D. ; Spitzer, L. ; Faltýnek Fric, Zdeněk ; Rindoš, Michal ; Vrba, Pavel
The material compiles conservation measures and methods for the care of endangered butterflies of open forests, protected by the EU Habitat Directive in the Czech Republic and under climate changes. These species are Euphydryas maturna, Lopinga achine, Parnassius mnemosyne, Coenonympha hero, and partially also Zerynthia polyxena. It results from predictions of vegetational and climatic changes of forest habitats, and outlooks of forest and water management conditions.

Sheep grazing as a controversial tool of nature protection
Daňková, Tereza ; Malíček, Jiří (advisor) ; Sedláček, Ondřej (referee)
Sheep grazing is currently more and more used as a main type of management in protected areas. However, it seems that in many cases this type of management has a negative impact on a habitat or species of interest. This bachelor thesis try to demonstrate how a care about pastures in term of nature conservation should be applied in a selected area. There are examples of endangered species that are directly threatened by an unappropriate sheep grazing. Positive and negative influences of grazing, especially sheep grazing, are summarized.
