Role of steroid hormones in control of sexually dimorphic traits in eyelid geckos (Eublepharidae)
Tóthová, Lucia ; Kratochvíl, Lukáš (advisor) ; Landová, Eva (referee)
The importance of sex hormones in formation, development and regulation of sexually dimorphic behavior does not need to be stressed. However, their actual organizational and activational effects and interactions in sexual differentiation and determination are not fully understood yet. The aim of our study was to explore the effects of hormonal manipulation in eyelid-geckos (family Eublepharidae) and enlighten the role of steroid hormones in formation of sexual differences. In the first part of our work we tried to reverse sex of Yucatán banded gecko (Coleonyx elegans) by hormonal manipulation in the early embryogenesis. This species has genotypic sex determination with chromosome set X1X2Y. In reverted individuals we aimed to examine the effects of steroid hormones on sexually dimorphic traits and in case of full sexual reversion and fertility of progeny, we would search for the sex-determining gene. In the second part, we studied masculinization effects of testosterone in females of leopard gecko (Eublepharis macularius). In contrast with the Coleonyx elegans mentioned above, this species has temperature dependent sex determination, even though these two species are closely related. Experimental females were implanted with testosterone implants and therefore their testosterone levels were increased in...

Project management in a selected corporation
Košíková, Lenka ; Švecová, Lenka (advisor) ; Tóthová, Lucia (referee)
The aim of the dissertation is to analyze the project management processes in a specific corporation from the point of view of a selected department. The introduction is dedicated to a closer view on the definition of the project. The following section, the presentation of the individual methodologies -- IPMA, PMBoK and PRINCE2 along with their comparison, is a knowledge-based input for the practical section. The introduction of the practical section focuses on the explanation of the project's origin, its scope and benefits. The project management is subsequently described within its life cycle. Each phase is concluded with a short chapter which summarizes the monitored process and contains a recommendation for improvements in the company's management. The conclusion is a personal summary of the project operation as it is and the project management in the selected department along with major points that would be convenient to implement.
