Naturalized cacti in Europe and their traits.
BRABCOVÁ, Šárka
Non-native plant species represent one of the many most significant threats globally. This work focuses on cactus invasions in 31 European countries. Cacti are classified based on European databases according to their status as occasional, naturalised, in-troduced, invasive and cultivated. The aim of the work is to compile a species list of the cactus family (Cactaceae), focusing on naturalized cactus species, their use and the identification of their compe-titive ability in new areas. The highest number of non-native cactus species is recorded in the Mediterranean region. The countries with the highest number of species are Spain, Italy and France. The most widespread species is Opuntia ficus-indica. The combination of horticulture based on non-native species, intense human pres-sure on the territory, travel, trade, transport of various materials and climate change have caused conservation problems in recent decades and increased the success of cactus invasions in Europe.

Positive and Negative Aspects of the Selected Forms of Governmen - Parliamentary Republic vs. Presidential Republic - Comparative Analysis
Brabcová, Šárka ; Sádovský, Stanislav (advisor) ; Stracený, Josef (referee)
The diploma thesis in question is focused on the selected forms of government: the parliamentary and the presidential republic. Before a comparative analysis of particular examples of states is done, other areas concerned with the topic have to be described. The first chapter depicts the state through its features, functions and forms. Then two essential forms of government - the monarchy and the republic - are specified in the historical and present context. The next chapter focuses on the model of separation of powers among the executive, legislative and judicial power, and specifies the relations between them. These relations shape the factual form of the government. Except the parliamentary and presidential system, other types of government are introduced, for example the dualistic monarchy, the semi-presidential republic etc. The aim of this work is to define, specify and compare the relations between the legislature and the executive in the Czech Republic and the United States of America. The result of the comparison is not evident because it is not possible to say which form is better. Both forms have their positive and negative aspects, it primarily depends on the historical background, traditions, political culture of the country, and these features set the base for the factual system.
