Song divergence of Philippine bulbuls (Pycnonotidae) on islands
Rulfová, Alena ; Policht, Richard (advisor) ; Turčoková, Lucia (referee)
Bulbuls (Pycnonotidae) are a biologically diverse group of songbirds that produce a variety of vocalisations. Their songs are very audible, yet the vocal behaviour of the majority of bulbul species has not been formally described or subject to bioacoustical study. The Philippine bulbul (Ixos philippinus) is a sedentary and endemic species of the Philippine archipelago. This thesis presents the first detailed descriptions of its song. The songs were recorded on five islands locations that covered eight different habitats. Nine song features of these species were compared, in order to understand song variations between different islands. In searching for correlations, habitat types and geographical distances between the islands were also measured. The songs of the species found on five islands were readily split up into three groups based on end frequency, syllable number and song duration. The correlations possibly relate to a late Pleistocene connection between the islands and colonization routes of the species. It was found that song frequency parameters in bulbul species is primarily affected by habitat, whilst the effect of current distances between islands was shown to be weak.

Diversity of European freshwater cyclopoid species: phylogeny, morphology and ecology
Krajíček, Martin ; Černý, Martin (advisor) ; Brancelj, Anton (referee) ; Wyngaard, Grace (referee)
Cyclopoids are together with Calanoids and Harpacticoids a part of the largest, very diverse group of crustaceans and the most numerous aquatic metazoans of the world. The history of their research goes as far back as to the beginning of 19th century when the first cyclopoid copepods were described. The taxonomy of cyclopoids started to develop gradually since that time, adding new and more detailed methods and morphological characters, as well as a certain degree of taxonomical confusion. In last decades, the molecular-genetic techniques of DNA sequencing have become available offering a new independent tool for taxonomists. This work contains different studies concerning the morphology, taxonomy, ecology, distribution and colonisation of cyclopoid copepods, with the use of molecular tools as a uniting element. Chapter 1 of this thesis summarizes basic knowledge about the taxonomy, morphology and biology of cyclopoid copepods and introduces the following chapters containing four studies presented as single publications. The taxonomy of copepods of the genus Cyclops is based mainly on the morphology which is sometimes ambivalent and some of the most problematic species groups are presented here. Chapter 2 presents our unique results, the first reconstruction of phylogenetic relationships among 15...

History and the present of Algeria and the development of the French language
Landová, Adéla ; Klinka, Tomáš (advisor) ; Machleidtová, Silva (referee)
Title of the thesis: The history and the present of Algeria and the development of the French language Keywords: Algeria, arabization, Arabian, Berber, French language, history, colonization, Maghreb, nationalism, independency, present, education Abstract: Algeria, the second largest country in Africa, is a part of an area called Maghreb. As well as other Maghreb countries, also Algeria has been influenced by the French colonization in the beginning of the 19th century. Not only did the colonization change the Algerian community, it mainly resulted in the introduction of the French language which is used in Algeria till this day. The target of this bachelor thesis is to outline the history and the present of this country, the development of the French and other languages such as Arabian and Berber, and also to comment on the development of the education system in Algeria. This bachelor thesis is divided into three main chapters that are chronologically arranged and that start with studying the history of Algeria. After that, they deal with the question of language in each particular historical period. The first chapter describes Maghreb from its furthest history up to the French colonization. The second chapter aims at the period of the French supremacy in Algeria and the last one chapter studies...

Comparison of selected traits at conspecific plants in disturbed and stressed environments localized within industrial waste deposits and their surroundings in landscape
Glier, Adam ; Kovář, Pavel (advisor) ; Štefánek, Michal (referee)
This study is oriented on the assessment of selected traits at conspecific plant which spontaneously colonize interior space within abandoned industrial area and/or deposits, and those ones occurred in adjacent vicinity. The work continues in previous studies concentrated on abandoned mine tailing containments where some important outputs consist of differences in plant adaptive strategies, growth rate, phenology, body size, ways of dispersal, ecophysiological or genetic parameters (Bryndová et Kovář 2004, Mrázek 2004, Zákravský et al. 2004, Jarolímová 2004, Kovář et al. 2004, Jiráčková et Dostál 2004, Kovář et Herben 2004, Dostál et Kovář 2013, Štefánek 2015, Urbanová et al. 2017). A part of the study includes the significance of small and large genomes at both types of habitats within defined phylogenetic framework. In other words - testing of the hypothesis: There is functional significance of small versus large genomes of plant species by comparing their occurrence in unreclaimed toxic deposits (landscape islands) with their populations from neighbouring habitats (large scale level). Key words unreclaimed industrial deposits in landscape, abandoned mine tailings, genome size, flow cytometry, conspecific taxons, plant traits, colonization, succession, disturbance, stress, restoration ecology,...

Landscape structure, habitat properties, species traits or chance: What determines distribution of grassland plants in abandoned fields?
Knappová, Jana ; Münzbergová, Zuzana (advisor) ; Hájek, Michal (referee) ; De Bello, Francesco (referee)
Semi-natural grasslands are among the most threatened habitats in Europe, endangered mainly by cessation of former management practices and conversion into other types of land use. Extensive research has been carried out in European grasslands in last decades, to explain origins of diversity and to provide guidelines for its conservation. However, the very slow response of perennial plants to landscape changes often impedes to accurately evaluate why species occur just where they occur and not elsewhere. Abandoned fields are perceived as potential habitats for species from declining grasslands. Indeed, many species are able to spontaneously colonise abandoned fields, but many other species are absent from communities that develop there. An important question remains what limits their successful establishment. By answering this question, we can gain also important insights into factors determining species distribution in grasslands because colonization of recently abandoned fields by grassland species is the ongoing process which is not obscured by historical changes in landscape structure. The very basic aim of this thesis was to evaluate the status quo of dry grassland plants in fields abandoned in last two decades. And in the second step, to identify what are the main constrains of successful...

Phylogeography and population structure of two loach species (Teleostei: Nemacheilidae) in Southeast Asia
Dvořák, Tomáš ; Bohlen, Jörg (advisor) ; Říčan, Oldřich (referee)
The freshwater fish species Schistura robertsi and Paracanthocobitis zonalternans belong to the family Nemacheilidae, which is distributed across whole Eurasia and with one species in northeast Africa. P. zonalternans occurs in lowland habitats through western Southeast Asia from Central Myanmar until northern Malaysia. The distribution area is of biogeographic interest, because it crosses several known biogeographic barriers, namely the border between Indian and Indochinese freshwater fauna along the Salween River, the Isthmus of Kra, the Krabi - Surat Thani line and the Kangar - Pattani line. In the present study, around 250 specimens of P. zonalternans from 62 localities across the whole distribution area were investigated using genetic (nuclear and mitochondrial sequences), morphologic and geologic data. The genetic data reveal the existence of seven major clades within the analysed material, each of them with a distinct geographic distribution area and only few cases of overlap, but with occurrence of some cases of secondary contact. Divergence time estimations suggested that P. zonalternans is about 18 my old, and a biogeographic analysis located the region of origin in the Tenasserim region (nowadays southern Myanmar). The global sea level fluctuations seem to have had a strong impact on the...

Negritude and a new poetic language, originated from colonial history
Šarše, Vojtěch ; Voldřichová - Beránková, Eva (advisor) ; Pohorský, Aleš (referee)
This work deals with Aimé Césaire's book Cahier d'un retour au pays natal, its function a value for author himself and for reader. At first, the paper explains, using linguistic and semantic analysis of chosen passages of this book, the liberation of author from the literary conventions and forms of his time, the quest of authentic style and his own poetic language. In the first part, the influence of french literature on Césaire's creation, precisely of Lautréamont, Rimbaud, Baudelaire, is explained. Afterwards, the work focuses on the emancipation tendencies which consist in the organic incorporation of the surrealistic practices and of creole influence into his poetry. In the second part, the paper attempts to give a description of author's determination to liberate the oppressed people, by the society, and his seeking of a new identity, based on omitted history of this people, on his ancestors and mainly on his forgotten roots. In the first place, indirect influence of the colonialism: his cruelty, enslavement, Triangular trade on Césaire's literary creation is described. The aim is to show the attitude of the author to the suffering of slaves and how he describes it to the reader and how he uses his heroes to accuse the colonialism of his cruel and usually atrocious practices to regain proud for his people.

Microbiota as a modulator of carcinogenesis
Benešová, Iva ; Kverka, Miloslav (advisor) ; Krulová, Magdaléna (referee)
Many studies show the ability of gut microbes to modulate the anti-tumour immune response by direct triggering the immune cells or by bacterial metabolites. Interestingly bacteria may even migrate to the tumour tissue and orchestrate the immune response on site. These anti-tumour effects can be improved by the administration of immune checkpoint inhibitors (ICI). Notably, some microbial effects occur only in the presence of ICI. On the contrary, microbiota may also promote tumour growth and negatively impact the effects of ICI therapy. We have disrupted the gut microbiota homeostasis by antibiotics (ATB) to study the effects of gut microbiota on the ICI. This disturbance led surprisingly to reduced tumour growth and enhanced pro-inflammatory immune response not only in the gut but also within the tumour tissue, where especially IFN-γ orchestrated the anti-tumour immune response. Importantly the anti-tumour immune response could be transferred through colonisation of germ-free mice by ATB-changed gut microbiota if concomitantly anti- programmed cell death protein 1 (αPD-1) monoclonal antibody was administrated. These mice had elevated levels of segmented filamentous bacteria (SFB), which induced systemic immune response with increased expression of IL-17 and elevated amounts of Th 17 cells,...

PhDr. Zdeněk Beneš, CSc. Abstract: The dissertation thesis intends to affect changes within the studies of medieval settlement in context with Czech historiography. It focuses on the relationship between the character of historiographical discourse and applied methods of research. The subject of relational analysis is both linguistic branches of Bohemian historiography. Changes in the specific field discourse are observed against the background of changes in Bohemian historical culture. Thus, the ways of multiplication of historical knowledge and the connection to the socio-political, cultural and institutional context of the observed issues are also monitored. The work mainly takes into account the territory of the wider historical Cheb region, which is used as a model example of changes in historical questioning depending on changes in historical awareness and social context of the time.
