Jagošová, Eliška ; Novák, Jan (advisor) ; Větvičková, Anna (referee)
Species diversity of vegetation is a result of not only present, but also past processes. Additionally vegetation is affected by local factors, as well as regional. Dry grasslands are significant due to their abundance of species. Farming and land-use changes lead to succession changes and subsequently also to changes in species diversity. The gradual degradation of habitats leads to a loss of species diversity, therefore, dry grasslands are becoming one of the most endangered vegetation types of Central Europe. The first part of this thesis focuses on dry grasslands in general. It presents the characteristics of this vegetation type, factors determining its occurrence and spread, historical context, threats, and possibilities of their protection. The second part focuses on evaluating the knowledge about dry grasslands in the region of Turnovská pahorkatina. The occurrence of this vegetation type within the framework of this region is marginal and centred only in specific habitats. This thesis also includes data about the occurrence of dry grasslands in the region of Turnovská pahorkatina and the characteristic of the natural conditions and historical development of these localities. The purpose of this bachelor thesis is to find out which of the factors affect the occurrence of dry grasslands in a...
