Derivational Morphology of Czech on Large Corpus Data
Faltusová, Marie ; Dytrych, Jaroslav (referee) ; Smrž, Pavel (advisor)
Subject of this thesis is study of word formation in the Czech language. The main aim is to create a module acquiring derivations from data of the electronic Dictionary of the Czech Language. This problematics has been solved by constructing three-level processing based on dictionary data. The first level is to obtain derivations from lemma definitions, the second step is making groups of basic forms according to their similarities, and the third stage is the evaluation of derivation pairs by number tag of derivation class to which they belong. I have managed to get more than 4 500 new words and evaluate over 20 000 derivative couples. The module has become a full-fledged part of the Morphological Analyzer of the Knowledge Technology Research Group, working at the Faculty of Information Technology of the Brno University of Technology.

Automatic Categorization of Unknown Words Based on Derivational Relations
Faltusová, Marie ; Dytrych, Jaroslav (referee) ; Smrž, Pavel (advisor)
This master thesis deals with the construction of a system for automatic classification of~unknown words based on derivation bonds. For this purpose, the system was designed to~extract derivative links based on electronic dictionaries and to create word-forming models from them. Based on this knowledge, it is then possible to incorporate unclassified words into existing nests formed from the obtained bonds, and their models, or create new ones. The reader will be gradually acquainted with the reasons that lead to the continuous transformation or expansion of the lexicon, the ways in which the words in~the~Czech language are derived and how to obtain information about the changes caused by this derivation process. This system builds on and extends the research of the branch of morphology in~the~project of a morphological analyzer of the Research Group of Knowledge Technologies, working at the Faculty of Information Technology of the Brno University of~Technology.

Základy užitkového chovu poštovních holubů a jejich etologie
PITZMOS, Jiří
The bachelor's thesis deals with the basics of commercial breeding of carrier pigeons and their ethology. The aim of this thesis is to determine the economic intensity of closed intensive breeding of medium size pigeons and to evaluate the factors influencing profitability. Part of the research is a breeding experiment in which utility and production parameters such as nesting frequency, hatchability, daily pigeon gains, yield in relation to food intake and ethological monitoring are monitored.

Nesting behaviour and population genetics of solitary bees (Hymenoptera: Anthophila)
Černá, Kateřina ; Straka, Jakub (advisor) ; Žďárek, Jan (referee) ; Paxton, Robert J. (referee)
My thesis is focused on nesting behaviour and population genetics of solitary bees. These two topics, although seemingly unrelated, bring much new information and thus contribute to the better understanding of solitary bee biology that is still insufficiently known. Although the solitary behaviour represents the necessary original state for the evolution of higher sociality or obligate cleptoparasitism, its role is largely unappreciated. Furthermore, intraspecific cleptoparasitism, which is an alternative and facultative nesting strategy in bees, is a probable antecedent state of obligate cleptoparasitism. Although the obligate cleptoparasitism is a very common strategy in solitary bees, the information about the frequency and the occurrence of intraspecific cleptoparasitism in solitary bees is rare. We studied the nesting behaviour of solitary bees to detect different behavioural patterns that could serve as preadaptations to sociality or cleptoparasitic behaviour and we also focused on the detection and description of intraspecific cleptoparasitism in solitary bees. We chose four model solitary species for these studies - Andrena vaga (Andrenidae), Anthophora plumipes (Apidae), Colletes cunnicularius (Colletidae) and Osmia rufa (Megachilidae). We described the behaviour of Andrena vaga at the...

Evaluation of breeding of birds of the order hornbills (Bucerotiformes) in selected zoos in the Czech Republic
ZÁHOROVÁ, Lucie
Hornbills have often been bred in zoos during recent years, not just abroad but also in the Czech Republic. These birds, characterized by long curved bill and casque, play an important ecological role in the wild as "forest farmers". Unfortunately their populations have been decreasing in the wild. Hornbills are facing habitat loss and food decline, they are hunted for their meat and for trade. Also some species are now commonly bred in captivity, the experience with breeding and rearing hornbills is not very extensive. Moreover, their specific nesting biology together with complicated social bonds rank hornbills to species with very low reproductive success. Therefore, appropriate breeding technique based on knowledge of the biology and ecology of the species is essential for successful breeding and rearing. The work effort of all zoos can in this way contribute to protection of the species in the wild. This theme describes conditions and results of hornbill breeding in Liberec zoo, Dvůr Králové zoo and Zlín Lešná zoo. Its goal is to determine the main factors influencing hornbill´s nesting in captivity.
