Mapping of heritage trees in the selected locality
HLUBOCKÁ, Denisa
The main aim of this bechelor's thesis is to map and desctribe the memorial trees in my chosen locations in Tábor district, to measure them (if possible) and to evaluate tzhe state of health overal. It goes on to equate motives for the preservation of memorial trees in the past, and especially in the present. I divided the care itself into its meaning at work, and further into abiotic and biotic factors. Last but not least, there is a reference to the principles of care and the cost of it. I also focused on the promotion of protection of memorial trees by the state - subsidy pro-grams etc. The District of Tábor, which I chose for my bachelor thesis, is located in the northern part of the South Bohemia Region. The district is bordered by the districts of Písek, Jindřichův Hradec and České Budejovice. Next, Tábor district adjoins Benešov district and a little with Příbram district in the Central Bohemian region and Pelhřimov district in the Highlands. This Bachelor thesis contains a description of the memorial trees and their mapping.

Breeding of Martens (Mustelidae) in zoos
TOMŠOVICOVÁ, Tereza
The aim of the study was to evaluate the breeding of martens in the Czech Republic. In this thesis the breeding in the Czech Republic and in Europe is monitored. In my work, I monitor the period between 1990-2021. Data on the Czech Republic were taken mainly from the yearbooks of Czech and Slovak zoological gardens. The data on breeding in Europe were drawn from the Species 360 database (Zoological Information Managament System). There are 14 species of martens in the Czech Republic. One of the most successful zoos was Chomutov zoo, which managed to breed a total of 47 Siberian weasel (Mustela sibrica). Another success story for Czech zoos is the breeding of the small otter, where a total of 79 cubs were bred between 1990 and 2021.

The use of headstarting in turtle conservation
PRŮCHOVÁ, Daniela
The bachelor thesis entitled The use of headstarting in turtle conservation was designed as a research thesis. The thesis is divided into five parts, which explain the issue of turtle endangerment and how this important and widespread group of nearly extinct and recent reptiles can be protected. The aim of the thesis is to explain the concept of headstarting, to identify the reasons for the threat to turtles and to evaluate whether and to what extent headstarting helps in the conservation of turtles. The first part communicates basic important information about turtles, both the biological classification and the important role of these reptiles in ecosystems. The second part details the reasons why all three groups of turtles - terrestrial, semi-aquatic, marine - are threatened, which is why headstarting has come into use for turtles. The third part of the thesis addresses reproduction in turtles, again for all groups, because of differences in reproduction in each group. The fourth part of the thesis discusses general information about headstarting, what headstarting options exist, and what criticisms there are towards headstarting based on the resources already available. The last important part of this thesis focuses on selected studies and research. The thesis includes research on selected species from each group of turtles to better evaluate and determine which groups headstarting helps, which groups it does not help, or if it affects the survival of a particular species of turtle.

The protection of small village Světnov against rural zone water
Humlíček, Aleš ; Novotný, Jaroslav (referee) ; Milerski, Rudolf (advisor)
The aim of this thesis is to propose appropriate flood protection measures in the small village Světnov, calculate the critical flood of guideline for very small basin and insert the data into the program HEC-RAS 4.1.0, where they will be further treated in order to find the most appropriate and effective solutions. As flood control measures will be designed two dry polders east of the village. Dikes should be designed so to be able to accommodate 100-year flood, which will be calculated according of guideline for very small basin. Of the materials community, we know that we need to convert flood into the existing pipeline, which is able to accommodate 1 m3/s. The thesis will design solutions dams, sewage channels and function objects in the program AutoCAD 2008.
