Grapevine cryoconservation
Faltus, Miloš ; Kotková, Renata ; Bilavčík, Alois ; Zámečník, Jiří
Storage of grapevine germplasm is endangered by biotic and abiotic stressors in the field conditions, and it is connected with the risk of valuable accession loss. Cryoconservation is a method which eliminates the risk and makes a safe long-term storage of plant germplasm possible. Cryoconservation method is based on storage of plant material at a temperature of liquid nitrogen when all processes are practically stopped but the viability of plant material remains. This methodology describes preparation of plant explants before cryoconservation, apical shoot tip dehydration by cryoprotectants, procedure and principles of long-time plant storage and plant recovery for evaluation of explant survival and regeneration. The Ministry of Agriculture of the Czech Republic is the user of this methodology and it will utilize it in the framework of “National Programme on Conservation and Utilization of Plant, Animal and Microbial Genetic Resources for Food and Agriculture”.

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.

The Possibilities of Animation in the Jewish Town in Trebic
Štěpánková, Petra ; Kouba, Vojtěch (advisor) ; Malcová, Zuzana (referee)
This bachelor thesis deals with the history of Jewish settlement in the town of Trebic, the origin of a Jewish ghetto and reasons for its preservation till today. The description of utilization and the positions of some important buildings is necessary for understanding the way of living and the administration of Jewish community in a separated ghetto. The thesis also describes the process of the revitalisation of Jewish Quarter during the last 20 years. Three basic revitalisation projects supported building rehabilitation and involved Jewish Quarter in the present life of inhabitants. Because of its uniqueness the whole complex was listed as the UNESCO sight. The practical part of the thesis which is devoted to the present-day utilization of objects in Jewish Quarter examines the reasons of its underutilised cultural potential. Using the methods of socioeconomic animation and the devices of the field of tourism, the practical part attempts to look for a solution of the destination and outlines a possible future utilization.

Challenges of Bengal tiger (Panthera tigris tigris) conservation in the tropics: lessons learned from the Chitwan National Park of Nepal
BHATTARAI, Bishnu Prasad
This research deals with the challenges of the conservation of tiger (Panthera tigris tigris) in the Chitwan National Park of Nepal and aims to be a model for tiger conservation in the tropical areas of other tiger range countries. Despite the high level of public concern and major investments during the last few decades for conservation, wild tigers continue to be under grave threat, and their preservation now requires, more than ever before, using reliable ecological knowledge for their conservation interventions. In this dissertation, I investigated various factors that affect on tiger conservation in this park: population status of prey, dietary patterns of tiger and its impact on sympatric carnivores (e.g., leopard) and increasing human-wildlife conflicts, effects of habitat structures and human disturbances on prey and predator species abundance and distribution.

Ecology of butterflies traditionally managed submontane meadows
ZIMMERMANN, Kamil
The persistence of Marsh fritillary (Euphydryas aurinia) and its relationships with five other closly related and co-occuring Nymphalidae butterflies was studied in identical habitat networks. Basic demography and dispersal patterns, and their consequences for conservation strategies, were investigated across mutliple sites and seasons.

Analysis of an environmental conflict - opinions of main groups of the inhabitants in the pond water area on the subject of the presence of cormorants (fishermen and holidaymakers) and media analysis
ŠÍPOVÁ, Martina
The thesis was chosen on the basis of the continuation of the bachelor´s work. This thesis is focused on the literature search of problems of the conflicts between the protection of cormorants and the interest of fishery, further on the media analysis in the Czech Republic and finally on the processing of opinions of various groups of respondents (holidaymakers in the area called ´Třeboňsko´ and Czech fishermen). The opinions of questioned people were obtained from controlled interviews written down and processed in the questionnaires. The available information shows that a number of the protected cormorants is increasing not only in the Czech Republic but all over the world. The increase of the number of cormorant population causes problems especially to fishery, because cormorants cause the damage by catching fish stock. These conflicts in the problem area are mostly promoted in the media. In the problem area there are important opinions of the key groups of inhabitants. Groups of questioned people demonstrated their knowledge: holidaymakers in the area called ´Třeboňsko´ have basic knowledge in cormorants and problems caused by cormorants. On the contrary, fishermen are well-informed about the problem. The fishermen are more interested in the problem. Media are very important for solving conflicts and forming opinions of various groups of people. Media analysis showed that most spokesmen, who initiated writing newspaper articles were just fishermen. Therefore the articles on the cormorants are negative and without opinions on the spokesmen as member of general public or academics. Results of the sociological analysis have feed back on the results of the media analysis. It was found out that in the Czech Republic there had not been drawn up any management of fish protection againts cormorants. That is why I prefer to suggest the management in the near future. I recommend to follow the existing foreign management, forexample, in Great Britain. Further, I propose to change the Czech legislation for lower payment of the compensation for the damage caused by cormorants.
