The topic of the bachelor thesis is the distribution of Antennaria dioica (family Asteraceae) in the Slovak Republic. The main purpose of the work was to create an electronic database consisting of Anntennaria dioica localities which were based on historical records and published data about the distribution of this species in various parts of Slovakia. First of all, I simply divided the records into phytogeographic units, then sorted them and began to rewrite other information as author, biotope, overweight, publication, year. After completing up the tables in the table program we can easily see that the plant have a broad vertical span from 250 m a.s.l. in the Nízke Beskydy Mts (Okrúhle) up to 2189 m a.s.l. in Tatra Mts (Jakubina). The most common habitat types are: meadows, pastures, road and forest edges, mountain slopes and ridges. The most common geological substrate is the limestone, but there may also be an andesite, granite or sridish substrate. Based on the vertical range and the position of the localities, we can find out that, the plant grows mostly in higher elevations and mountain areas, which also reflects on the representation in phytogeographical units. The most concentrated distribution of the plant species is in the areas: Strážovská hornatina Mts, Slovenské Stredohorie Mts, Low Tatras, Fatra Mts, Javorníky Mts, Západné Beskydy Mts, Spišské pohorie Mts and Slovenské Rudohorie Mts, where the highest amount of localities and data have been recorded. On the contrary, the low represented areas were: Tribeč Mts, Bukovské vrchy Mts, Podunajská nížina lowland, Košická kotlina basin, Devínska Kobyla Mts. Phytogeographical units with zero representation: Burda, Záhorská nížina, Východoslovenská nížina; where any locality have not been registered.
