Cryptic diversity of freshwater alga Synura sphagnicola (Chrysophyceae, Stramenopiles)
Slámová, Pavla ; Škaloud, Pavel (advisor) ; Dvořák, Petr (referee)
A common alga of oligotrophic slightly acidic fresh water habitats, Synura sphagnicola, has never been suspected for a presence of cryptic diversity. The publicly available SSU rDNA sequences showed very slight genetic differences between the S. sphagnicola isolates. However, I suspected that if any cryptic lineages exist, the sequencing of ITS region will show the differences between them. A total of 37 S. sphagnicola sequences (36 from Europe and 1 from Korea) were analyzed in this thesis. The ITS rDNA sequencing clearly recognized the presence of two distinct cryptic species, referred here as lineage SP1 and SP2. The morphological analysis of 14 cultivated strains (6 belonging to the lineage SP1 and 8 to the lineage SP2) validated the genetic distinction. The statistical analyses showed that 4 morphological aspects (length of a scale, width of a scale, length of a spine, length of a rim) were found to have significant differences in length of measured factors between species. The most visible difference is in the length of a spine that is connected to the scale. The analysis of published S. sphagnicola scales showed that the two lineages can be morphologically distinguished also in natural conditions. According to the morphological analyses, the lineage SP2 (species with a longer spine)...

History of One Theatre (About the Amateur Theatr Group Šupina)
NESTÁVALOVÁ, Vendula
The bachelor thesis deals the effects of an amateur theatre group ?Šupina? at the end of the seventies and eighties of the twentieth century in Vodňany. The work describes the history and transformations the part of this authorial theatre, analyses its dramaturgy that formed the specific ensemble´s poetics and provides informations about the influence for the significant exhibitions of the amateur theatre not only in the Czech Rebublic but also abroad. This thesis is based on the former press and mapped the theater´s activities.
