Functions of secondary metabolites of lichens
Zvěřinová, Gabriela ; Svoboda, David (advisor) ; Bouda, František (referee)
This bachelor thesis is a review of available literature about lichen secondary metabolites and their functions. Lichens produce a great variety of these compounds; most of them are unique to the lichen symbiosis and are not found in higher plants. Besides the role of these compounds in chemotaxonomy and systematics, lichen secondary metabolites exhibit various biological functions and can affect biotic and abiotic interactions of lichens with their environment. Well-known and often described functions of lichen substances include especially antimicrobial, antiherbivory and antioxidant activity, allelopathy, metal homeostasis and photoprotection. This thesis is focused on these functions and summarizes current knowledge in this area. Key words: lichen, secondary metabolites, allelopathy, antimicrobial activity, herbivory, antioxidant activity, photoprotection, metal homeostasis, pollution tolerance, literary review

Lichens growing on diabasic rocks
Lenzová, Veronika ; Svoboda, David (advisor) ; Bouda, František (referee)
This bachelor thesis is a review of available literature about the lichens growing on diabasic rocks. Diabasic rocks are volcanic rocks of upper proterozoic and lower paleozoic age. They occur in the Czech Republic in Barrandien and Nízký Jeseník areas only. The most investigated sites concerning lichens are the Berounka river valley and Prague region. Diabasic rocks are very suitable substrate for lichens due to specific properties and these rocks provide greater lichens diversity in comparison to the other substrates. This thesis contains list of 213 lichen species, which were published on diabasic rocks within the Czech Republic. According to the literature 3 lichen species have been found only on diabases in the country.
