Functional traits and functional diversity in lichens
Kolenská, Lucie ; Malíček, Jiří (advisor) ; Vondrák, Jan (referee)
Functional traits are a discussed topic across disciplines and articles with lichens are published as well. Traits are the attributes that define the organism from morphological features through anatomy to the physiology of the individual, including interaction in environmental and environmental influences. The most frequently studied functional trait of lichens is the type of thallus. Another commonly studied trait is the type of photobiont, where the presence of algae Trentepohlia is negatively affected by frost and because of this its number decreases with increasing altitude. Another functional trait of lichens which is studied is reproduction, and also secondary metabolites, which protect lichens, for example, against UV light or herbivores. Functional traits together form functional diversity, which is another way how to measure diversity on a planet where the most diverse ecosystem is not always the one with the highest number of species. Functional diversity indices then can reveal unique communities that should be protected. However, neither the definitions nor the calculation of functional diversity are exatly specified, we use different indices. The Rao index of quadratic entropy is most often used for lichens. Keywords indices, lichenized fungi, mycobiont, photobiont, thallus

Epiphytic species of Lecanora subfusca group in the Czech Republic
Malíček, Jiří ; Palice, Zdeněk (advisor) ; Vondrák, Jan (referee)
The main aim of this bachelor work is to summarize knowledges on species of the Lecanora subfusca group growing in the Czech Republic, eventually taxa their occurence may be expected in our area. Only epiphytic and/or epixylic species are included in this study because of a large diversity of the group. Ten taxa have been published from the country. This group is poorly explored in Central Europe because of difficult determination of single species. A comprehensive treatment is lacking in this area. For most taxa of this group only limited information on ecology, distribution, chemistry and taxonomic concepts exists. The present work is reviewing up-to-date knowledge of this group. Historical sources were based mainly on morphological and anatomical data. These were evaluated and excerpted. The bachelor work should serve as a basement for the following diploma thesis.

Diversity and phylogeny of symbiotic partners in zeorin-containing red-fruited Cladonia species.
Steinová, Jana ; Škaloud, Pavel (advisor) ; Pérez-Ortega, Sergio (referee) ; Vondrák, Jan (referee)
Lichens are a classic example of mutualistic symbiotic associations, yet the views on lichen symbiosis have changed considerably during the last fifty years. Nowadays, lichens are generally understood to be microecosystems consisting of several symbiotic partners which contribute in different ways to the prosperity of the whole system and which differ by the strength of their bond to other symbiotic partners. The level of knowledge of the individual partners (mycobionts vs. photobionts vs. bacteria) varies greatly in terms of their specificity, diversity and in the forces that shape this diversity. The main aim of this work was to reveal the diversity of organisms participating in lichen symbiosis and to better understand the biological forces which shape this diversity. We worked with a relatively common lichen group, zeorin-containing red-fruited Cladonia species, and specifically, we focused on the mycobionts, photobionts and bacteria that participate in this association. During the course of the study, it became apparent that species delimitation, which is a fundamental requirement for accurate diversity estimates, is another topic that requires further research. Our analyses revealed that species circumscription of most of recently recognized Cladonia mycobionts cannot by supported by...
