Streptophytic Algae with a Focus on the Class Zygnematophyceae
Špička, Jan ; Soldán, Zdeněk (advisor) ; Ráček, Jan (referee)
This bachelor's thesis deals with streptophyte algae, with special attention given to the class Zygnematophyceae. The thesis is written as a literature review, aiming to summarize existing knowledge about streptophyte algae, particularly focusing on the class Zygnematophyceae. Additionally, the thesis elucidates the phylogenetic relationships within this group, which historically have been challenging. The thesis primarily focuses on the description, ecology, and taxonomy of streptophyte lineages, emphasizing their significance in the study of terrestrialization, or the colonization of land. A significant part of this thesis is therefore to highlight the ecological and evolutionary role of streptophyte algae, especially in the context of their adaptation to terrestrial environments. An additional aim of the thesis is to address the issues associated with the group of algae, given their inconsistent definition. The thesis points out that algae do not form a monophyletic group, as they encompass various taxonomic lineages. This thesis can serve as a foundation for further research in the field of algology, thereby contributing to a better understanding and orientation in the process of terrestrialization. It also indicates the need for more phylogenetic studies to enhance understanding of the...

Comparative analysis of book reviews on the social site Instagram and in literary magazines
Sladovníková, Eliška ; Čeňková, Jana (advisor) ; Malý, Radek (referee)
The popularity of bookstagram accounts is gaining momentum and reach. For this reason, the thesis focuses on the format of book reviews both on Instagram and in literary and online magazines. The aim of the thesis is to define the structure of book reviews on Instagram and in literary magazines, the nature of bookstagram, and, above all, to assess whether bookstagram influences literary reviews. Another objective is to explore the perspectives of literary reviewers and bookstagrammers on book content on Instagram. The theoretical part mainly deals with the definition of book reviews and literary criticism, methods of text interpretation, and also defines new media and social networks, with a specific focus on bookstagram. In the analytical part, book reviews of Šikmý kostel are first described through direct description in both types of media. Subsequently, they are compared in several key categories such as the presence of the book's context, language form, or topics. Semi-structured interviews with literary reviewers and bookstagrammers follow, including two informants who engage with both media. The research section thoroughly analyzes the structure of book reviews and the opinions of their authors, providing insights into the characteristics of high-quality reviews, texts on bookstagram, and...

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

Maňák, Vratislav ; Čeňková, Jana (advisor) ; Malý, Radek (referee)
The rigorous thesis "The Poet Sings Poorly. The Media Response to The Song about Viktorka by Jaroslav Seifert in The Fifties of 20th Century" deals with the campaign set against the poet Jaroslav Seifert and his piece "The Song about Viktorka".

It attends to the cultural, political and medial conditions in the turn of the 40s and 50s and it also analyses Seifert's position in this period. It investigates the acceptance of Seifert's poetic skills after the year 1948 and also it describes poet's political profile and his relationship to the communist party. It follows in details by broad circumstances which the critics of Seifert's poem "The Song about Viktorka" provoked and which were extended until the inter-war period. It analyses the reviews of the mentioned Seifert's piece of work, its impact on poet's future life and the cultural area of the beginning of the fifties. The aim of the rigorous thesis is to set a comprehensive view of the affair Seifert had to face up with. It can also be used as an example of...
