Taxonomy, phylogeny and phylogeografy of selected groups of aquatic beetles (Coleoptera: Hydrophilidae, Hydraenidae) of the Caribbean region
Deler-Hernández, Albert ; Fikáček, Martin (advisor) ; Ribera, Ignacio (referee) ; Archangelsky, Miguel (referee)
This thesis is focused in the representatives of beetle families Hydrophilidae and Hydraenidae of West Indies and adjacent regions. It consists of two parts, the phylogenetic part and the systematic part. The phylogenetic part focuses on the hydrophilid genera Phaenonotum and Crenitulus of Greater Antilles: beetles were sampled in all four main islands (Cuba, Hispaniola, Puerto Rico and Jamaica) and analyzed using the combination of molecular and morphological data. The genus Phaenonotum contains four single-island endemics, of which those from Cuba, Jamaica and Hispaniola are wingless and form a clade that diversified ca. 46 million years ago (Ma) and likely colonized the Caribbean via the GAARlandia land bridge. In contrast, the Puerto Rican endemic and the two remaining non-endemic species colonized the Greater Antilles by over- water dispersal during the Oligocene-Miocene. The analysis of the genus Crenitulus revealed that Greater Antillean species belong to two separate clades: the Crenitulus yunque clade endemic for Cuba and Hispaniola, and the Crenitulus suturalis clade containing specimens from Greater Antilles and from northern America. A detailed revision of the Crenitulus yunque clade using morphology and molecular-based species delimitation recognized 11 species locally endemic for...

Thematic atlas of the Prague islands
Krusová, Anna ; Lysák, Jakub (advisor) ; Janata, Tomáš (referee)
The aim of the work is to create a thematic atlas, the content of which are maps of selected lesser-known Prague islands, mostly inaccessible by foot. The partial goals are the identification of all islands in Prague using spatial data and analysis, evaluation of existing and acquisition of own spatial data, which are then used to create detailed maps of selected islands and processing of an atlas with additional texts and images. In theoretical part, literature and available sources of data on the Prague islands are researched and the work is placed in the context of cartography. The practical part describes the whole process of the atlas compilation, from the identification of individual islands through field survey to cartographic processing of the obtained spatial data and finalization of the resulting work. The output of the work is the Thematic Atlas of the Prague Islands, which was made made using ArcMap and InDesign software. Key words Prague, islands, thematic atlas, thematic cartography

Funkční diverzita ptačích společenstev na ostrovech Oceánie
KOTOUNOVÁ, Adéla
Functional diversity is important part of biodiversity. It describes how organisms influent enviroment and how organisms respond to changes in the enviroment. First, I reviewed current knowledge, because the research of functional diversity accumulates exponentially, and new indexes appear quickly. The functional diversity is mostly calculated for plant communities, for which we have majority of available information those is nowadays the most available information. To fill knowledge gaps, I aimed to describe the functional diversity of bird communities on the islands of Oceania.

Mountains as islands
Kačabová, Petra ; Storch, David (advisor) ; Ferenc, Michal (referee)
In this paper I deal with island biogeography and its applicability to isolated mountaintops, as an ecological equivalent of true islands. I discuss both true and mountain islands regarding their origin and the influence of long-term climate evolution on Earth. I underline some features of mountain islands, resulting from their topography and the dissimilarities of both types of island barriers. I find that mountain and true island communities might or might not have a number of species in a state of equilibrium, caused by balance between species immigration on island and their extinction. If the number of species on island is not in equilibrium, species extinction is not balanced by species immigration. I consider patterns of island communities, mainly nestedness, which has been frequently studied on mountain, as well as true islands. I discuss distribution patterns concerning invertebrates. And finally, I concentrate on recent methods of moutain island research and discuss mountain island isolation issues in terms of global warming.

Functional changes of Prague Vltava islands
Steyerová, Michaela ; Fialová, Dana (advisor) ; Kupková, Lucie (referee)
FUNCTIONAL CHANGES OF PRAGUE VLTAVA ISLANDS The aim of this thesis is to document and analyze functional changes of Prague islands on the river Vltava, with emphasis on their use for free-time activities. This work focuses particularly on the development of Prague islands during the last decade. Directed interviews with main contemporary personalities who are performing their activities on the islands, standardized interviews with visitors on selected islands and knowledge from field research were used to accomplish the aim of the thesis. The work on this thesis also included collection of historical materials (maps, photographic documentation) for a planned exhibition as one of the outputs of this work which would be a way how to present scientific results by popular means. Keywords: Prague, islands, Vltava River, leisure time activities, exposition

French language in Indian Ocean
Antropiusová, Andrea ; Kalfiřtová, Eva (advisor) ; Jančík, Jiří (referee)
La Réunion, Madagascar, Mayotte, Seychelles, Comoros and Mauritius are a colony of France located in the Indian Ocean. The target of this bachelor thesis is to outline a situation linguistic and variety of French language in this territory above mentioned. This bachelor thesis is divided into five main chapters that are divided into five lesser parts. The fifth chapter is divided into three chapters include the linguistic discipline (phonetics, morphology and syntax, lexicology). All chapters are chronologically arranged and start with studying the geography, the history, the population, the linguistic situation and variety of French.
