Evaporative water loss in geckos of the genus Paroedura
Myslíková, Tereza ; Starostová, Zuzana (advisor) ; Okrouhlik, Jan (referee)
Keeping a balanced state in terms of liquids in an organism, especially evaporative water loss regulation, is essential for all terrestial animals, including reptiles. Respiratory water loss and cutaneous water loss account for the highest percentage of total water loss. For this reason, the degree of evaporative water loss in reptiles can be primarily influenced by body dimensions, metabolism intensity and morphology of body surface scales. This thesis focuses on water loss through evaporation in Madagascan Paroedura geckos. The Paroedura are suitable for this research because they represent a monophyletic genus with a strongly supported hypothesis about phylogenetic relationships. The thesis adds some facts to this theory. At the same time, individual Paroedura species differ in body dimensions and habitat preference. The aim of the thesis was to find out whether individual representatives of Paroedura differ in TEWL, to specify the characteristics of the ancestral state of TEWL in this genus and to test which morphological and physiological factors influence TEWL. Further aim was to measure cutaneous water loss. Measuring was carried out by flow- through respirometry. The results show that individual representatives of Paroedura differ remarkably in TEWL figures. The reconstruction of the...

Count Maurice de Benyovszky and the central European literary reflections of his life and work
Beňačková, Miroslava ; Kolmanová, Simona (advisor) ; Benešová, Michala (referee)
The aim of this bachelor thesis is to focus on the traveler, adventurer and Madagascar king Count Maurice de Benyovszky, his life and his work, and to discuss his personality and his significance within the Central European region. We will attempt to name the differences between his portrayal in the literary works of the mentioned area, find the reasons for them and confront them with the historical reality. In addition to that, we will pay attention to various editions of his memoirs and the way of translating them to Slovak and Hungarian language as well. Key words Maurice de Benyovszky, traveler, Madagascar, Central Europe, adventure novel, biography, memoirs, diaries

Madagascar stem succulents, protected by CITES, in collections in the Czech Republic
KOUPAL, Vít
The bachelor thesis focused on review of representation of Madagascar-based stalk succulent plants as one of the main groups of collection plants under protection of CITES in the selected collections in the Czech Republic. The collections under monitoring were Botanic Garden of Natural Science Faculty of Masaryk University in Brno, Botanic Garden Libverda Děčín, Botanic Garden Liberec, Zoological and Botanic Garden of Plzeň City, Botanic Garden of Prague Capital City, Botanic Garden Teplice and a selected private collection. Data about representation of monitored herbal species were taken based on personal visit and provided lists. Florius registration programme was used for completion of data. Review of the species diversity based on representation of families showed dominant representation of Euphorbiaceae family followed by important representations of Apocynaceae and Didiereaceae families. The species of Madagascar-based stalk succulent plants registered in Appendix I and II of the latest CITES list were represented in approximately equal proportion in majority of the collections. The exceptions were two collections (Botanic Garden Liberec and private collection) with higher representation of species from Appendix I. From the point of species composition, the collections of Zoological and Botanic Garden of Plzeň City, Botanic Garden of Prague Capital City, and the private collections significantly differentiated from the other collections.

International trade in Malagasy succulents, protected by CITES
KOŠKOVÁ, Irena
Harvesting of endangered plant species from wild nature for trade purposes as well as reduction of natural habitats are the main reasons for lost populations in wild nature. CITES listed the endangered species, for which trade control is required, to its list. Included in the list is majority of Madagascar-based succulents plants. This thesis reviews trade with the Madagascar-based succulent plants protected by CITES between the Czech Republic and other countries. The trade was reviewed based on data from CITES Trade Database administered by UNEP WCMC for periods between 1992 and 2012. The most frequent reason of the trade with the selected group of plants was commercial interests. The main country of import and re-export was Madagascar with dominant share of specimens originating from wild nature. Almost all specimens were live plants from Appendix II. The share of represented genus in import, re-export and export was very similar. The development trends were not demonstrable from the statistical point of view.
