Srovnání diverzity vybraných skupin epigeických členovců v hospodářském nížinném lese s různou věkovou strukturou a typem managementu
Staněk, Luboš
The aim of this thesis is to investigate the species richness and abundance of epigeic arthropods (spiders, ground beetles, centipedes, millipedes, woodlice) in relation to different age structure and types of forest management. The arthropods were sampled from four different age classes (clearings, young, middle-aged and old forest stands), while within two of them (clearings and old forest stands) the influence of management was also evaluated. According to comparison of stages of forest succession most species were found in clearings without any mechanical soil preparation. On the other hand younger age classes hosted the least amount of arthropod species. The highest abundances of species were detected within young forest stands whereas the lowest in middle-aged stands. The results of forest management impacts indicate that soil milling is not suitable for any investigated group of organisms. The response to management of the old stands varied for different arthropod groups. The results reveal high importance of diversified silviculture in form of various age classes, a regulation is also necessary to restrict large area milling of clearings and for both managed and unmanaged forest stands the continuity must be maintained.

Terrestrial Isopods as Model Soil-forming Agents in Practical School Education
Korbélyi, Tereza ; Mourek, Jan (advisor) ; Nodžáková, Kateřina (referee)
- 2 - Abstract Woodlice (Isopoda) belong to major soil decompositors of plant material and at the same time easily collectible. These organisms are therefore suitable for integration into practical school lessons. The aim of this thesis is therefore to design inquiry-based education using Isopoda as an example of soil decompositors. The first part of this thesis is focused on the theoretical introduction to inquiry- based education. It is also devoted to describe woodlice (Isopoda), explain their morphology, life cycle and cover the most common species of Isopoda occurring in the Czech Republic. A simplified determination key for these most common species is included. The second part of the thesis includes complete instructions on how to use these organisms in practical teaching with elements of inquiry-based education. The manual contains techniques for collecting and storing woodlice. The manual also contains instructions to individual experiments, including the list of needed tools and advice, where to obtain the tools and other didactic materials. The third part of the thesis has a research character, where, based on a questionnaire survey, students' attitudes towards woodlice (Isopoda) and their knowledge shift before and after the practical lesson are evaluated. Keywords Isopoda, inquiry-based...

Optimization of breeding in tropical woodlice Trichorhina tomentosa.
BĚHOUNEK, Ladislav
This thesis was created for the purpose of determination whether the production of the tropical woodlice Tichorhina tomentosa can differ depending on served food. Tropical woodlice are innovative species of fodder insect in terraristics therefore there are not many studies about their farming. This fact became one of the main causes of this fodder insect species choice for my study. Another aspect was relative farming easiness. Woodlice were kept in the same conditions and divided into four groups. Every single group was given a different kind of food. Data collection was carried out every week the number of woodlice was measured. It was found by statistic method that served food influenced the tropical woodlice production. In the experiment the populations which were given oat flakes and dry dog food were growing most quickly. This fact might help not only fodder insect breeders to better production of tropical woodlice.
