Plant traits determining plant-herbivore interactions
 Medová, Tereza ; Münzbergová, Zuzana (advisor) ; Skuhrovec, Jiří (referee)
Plants are constantly endangered by herbivores. Plants have adapted and created a wide arsenal of defences during approximately 410 million years of coexistence. Their role consists of fading the herbivores off or reduce suffered damage. This bachelor's thesis focuses on mechanisms that were proven to serve as plant defences. It is specifically about interactions between invertebrate herbivores and plants of terrestrial ecosystems. Prediction of herbivory by some traits is mentioned as well. Information about characteristics of plants which affects preferences of herbivores is interesting due to its possibility of aplication in agriculture or biological control of invasive species.

The importance of enviromental conditions on plant-invertebrate herbivore interactions
 Kuglerová, Marcela ; Münzbergová, Zuzana (advisor) ; Skuhrovec, Jiří (referee)
Plants and herbivores influence each other for more than million years. Most studies are focused on interspecific variability in herbivory intensity, but little i known about intraspecific variability and what controls it. Environmental conditions can determine intraspecific variation. Goal of this thesis is to examine importance of environmental conditions and interspecific variation for invertebrate herbivory preferences. Plant material that was used in experiments comes from several species from subfamily Carduoideae. Preferences of invertebrate herbivores are tested in food-choice experiments. Plastic arenas are made for these experiments, in which leaves are put in small tubes that are placed along the periphery. After herbivores are placed in to arena, arena is covered by net to ensure that herbivores can't escape. Plant material for experiments was grown in experimental garden and was also brought from field. Plants from garden differ in productivity of soil and water regime. In experiments with field material, plant leaves were collected from eight localities, four fields and four grasslands. Leaves were scanted before and after each experiment. Scans were processed and the amount of consumed leaf tissue was determined. For plant characteristics I measured plant functional traits, specific...
