Epiphytic lichens of the Czech Republic
Pelechová, Kateřina ; Svoboda, David (advisor) ; Peksa, Ondřej (referee)
This bachelor thesis researches the works of the years 1908-2013, which deal with the occurrence of epiphytic, i.e. growing on tree species, lichens in the Czech Republic. In the introduction there is briefly interpreted definition of lichens and epiphytes and the relationship between lichens and heir environment (with an emphasis on air pollution) is described. The main part is devoted to the processing of data found in the literature - when and on which tree species is the lichen growing - and is divided into two periods (1908-1970 and 1971-2013). The frequency of lichen species changes between periods - links between lichens and tree species and preference of the species and its changes over time, changes in preference of pH of bark of trees and tree species with the highest number of species of lichens. The study contains a list of 429 lichen species occurring on tree species in the Czech Republic. Powered by TCPDF (www.tcpdf.org)
