Characters used for determining of spiders (Araneae)
KRIŠTOFOVÁ, Lucie
This bachelor thesis focuses on a current issue of classifying spiders into their families. The incorrect recognitions of a family are often caused by inappropriate choice of morphological features and their ambiguous characteristics for determination usage. In a literary review, various morphological characters of spiders used for their determination to families are summarized and described. Subsequently, two Czech keys were tested by respondents, which provided a view of the steps and features causing difficulties in classifying spider families. Thus, I outline both unquestioning acceptance of features from older sources and the fact that their usage is not always a reliable tool for determination. Often neglected is the attitude of inexperienced observers who look upon the spider body inexpertly, not being influenced by arachnological traditions, and therefore, with a certain dose of exaggeration, objectively. This is the reason why the research was done mainly with the help of amateur public. In the final parts of the bachelor thesis, I both discuss problems that emerged and were recorded during the observation and recommend suitable improvements concerning the classification keys.

Determining key to monitors for the need of CEI - extended version.
ZELENÁ, Andrea
Present B. Sc. is a continuation of previous B. Sc. thesis "Dermining key to monitors for the needs of CEI". This extended version contains all 73 species recognized in present time and complements the previous key which describes only species of the most traded monitors in the Czech Republic. All representatives of the genus Varanus (monitor) are included on the CITES lists - Convention on International Trade in Endangered Species of Wild Fauna and Flora. CEI is the main supervisory authority of mentioned convention in the Czech Republic. CEI is authorized to retain illegally imported specimens. Determination of monitors is a very complex issue because monitors are unique to their number of color variants and wide size range. The B. Sc. contains table of identifying criteria and based thereon understandable model of determination key which is certified by testing. Monitors are of interest to breeders around the world. It is confirmed by data of the online stores that demonstrate continual growth of monitors attractiveness on the market.
