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...

Legal regulation of wild animal protection
Křížová, Barbora ; Fabšíková, Tereza (referee)
Legal Regulation of Wild Animal Protection Abstract The dissertation deals with the protection of wild animals and its legal regulation. Wild animals are protected within the biodiversity protection and nature and landscape conservation, which can be divided into territorial and species protection, while the dissertation focuses mainly on the species one. In addition to the explanation of basic terms, the dissertation consists of three main parts, which focus on the international, European Union and Czech legal regulation. The first part on the international law analyzes the Convention on Biological Diversity, the Convention on International Trade in Endangered Species of Wild Fauna and Flora, the Convention on the Conservation of Migratory Species of Wild Animals and the Convention on the Conservation of European Wildlife and Natural Habitats. The next part on the European Union law mentions pertinent conceptual tools and subsequently the relevant directives and regulations. These include, above all, the Birds Directive, the Habitats Directive, the Zoos Directive, the Regulation on the Protection of Species of Wild Fauna and Flora by Regulating Trade Therein, and the Regulation on Invasive Alien Species. The third main part pays attention to the Czech legal regulation. First, representative conceptual...

How to become a critically endangered species: a review of the distribution and status of the crucian carp (Carassius carassius)
Janda, Benedikt ; Choleva, Lukáš (advisor) ; Lojkásek, Bohumír (referee)
The Crucian carp (Carassius carassius) is the native species of fish in European standing and slowly flowing waters. Thanks to their high resistance to adverse abiotic conditions, they also inhabited dead arms of river, ponds and floodplains. Despite its resilience, this species has been declining or completely retreating from the most of natural habitats since the middle of the 20th century. The negative direct human interventions into the species populations were, intensive fishing and the elimination of suitable habitats as a result of landscape defragmentation, which was part of flood control measures. Secondly, the human-made introductions of non-native species, the Gibel carp (Carassius gibelio), capable of gynogenetic reproduction, strongly competes with the native species for resources. The extent to which the situation of the native Cruvian carp is critical and ow it has historically occured is revised in the formo f literaly search by this bachelor's Thesis. Keywords The Crucian carp, gynogenesis, molecular genetic methods, cytochrome b gene, taxonomy, hybridization, introduction, microsatellites

The story of the European beaver on the territory of the Czech Republic
Kletečková, Aneta ; Kostkan, Vlastimil (advisor) ; Bartoš, Michael (referee)
This thesis deals with the controversial species of the animal, the European beaver, which is perceived very differently in the human society. In the history, this especially protected animal was extincted on the territory of the Czech Republic and actually his activites frequently come into conflicts of human interests so the comeback of beavers is not always welcome. The thesis describes the process of changing situation of the population of beavers in the Czech Republic and important aspect of their existence. The practical part of the thesis is pursued on the research, which is focused on the perception of the problematic issues of the european beaver by the experts in the Czech Republic. This research is based on seven expert interviews and also on the survey. The goal of my research was to gain comprehensive informations about the perception of experts and about their recommendations how to moderate the situation and harmonize the human - beaver relationship. The main contribution of this thesis is the cooperation all key goups of experts and primary the most important is that results from the research can be used as a material for the future expert debates. Key words: European beaver, species protection, experts, nature preservation, Czech Republic

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.

Human preference to animal species and its impact on species conservation
Marešová, Jana ; Frynta, Daniel (advisor) ; Komárek, Stanislav (referee) ; Sedláček, František (referee)
The dissertation thesis deals with human aesthetic preference to other species and its anthropological and conservation aspect. The aesthetic preference to animal species has rarely been systematically studied before and quantitative analyses, especially on a fine taxonomic scale did not exist. On the other hand, it was known that attractive species often receive more support for their conservation. From these simple facts rose the idea to test human aesthetic preference to snake species (and consequently to species across major vertebrate taxa) and use this quantified preference to explain the conservation effort devoted to captive breeding worldwide (measured as size of zoo populations). We confirmed that the perceived attractiveness (preference and/or species' body size) succesfully predicts the size of zoo populations across mammal, bird and reptile taxa. On contrary, we found no effect of the IUCN listing of the species. To find out whether we work with Czech students' preference only or we may generalize to other populations, we carried out the same experiment to determine human preference to boas and pythons in eight cultures of five continents. Despite profound differences of the studied ethnics, we revealed a considerable agreement. Moreover, we found an agreement between pre-school...
