Floral biology of tropical alpine plants
Holzbachová, Lucie ; Sklenář, Petr (advisor) ; Ptáček, Jan (referee)
Tropical alpine environments are characterised by specific environmental conditions to which the local plants adapted through evolution. The specificity is especially in a strong diurnal climate with temperatures falling below zero at nights. At the same time, this environment lacks thermal seasonality, which allows growth and flowering throughout the year. While floral biology is relatively well described in temperate regions, it has only been studied sporadically in the tropics. This study summarises the knowledge of floral biology in tropical alpine environments with a focus on zoophily plants. The principal part of this work is dedicated to floral traits, focusing on flowering phenology, which is diversified for every species during the year. In this way, plants face competition, especially for their pollinators, which decrease in abundance with altitude. Although not all phenological strategies have been studied so far, we can find several main flowering schemes. This literature review points to unexplored research topics about floral biology of plant inhabiting tropical mountains that might provide a basis for future studies.

Anatomy and functional ecology of tropical alpine plants in South America
Gorčicová, Barbora ; Sklenář, Petr (advisor) ; Stančík, Daniel (referee)
The bachelor thesis discusses the plants in the páramo. The first part describes unique environment located at high altitudes of the tropical South America, the páramo. The uniqueness of the environment is caused by several basic conditions. The most important ones are significant daily temperature fluctuations, tropical climate stability during the whole year and high altitude. Anatomy of adapted plants, discussed in the second part of this work, conform to the extreme conditions. There are specific páramo life forms thanks to the uniqueness of the environment. The leaf structure and the vascular system of the plants are significantly modified in terms of anatomy. Although there are quite specific (and therefore interesting) life forms in the páramo, the current knowledge of the plant anatomy is minimal. The last part of the thesis suggests the questions for my future master thesis, which will contribute to better understanding of this underexplored topic.
