The importance of horizontal precipitation for growth of juvenile stages of Dragon tree on Canary Island
Lengálová, Klára
Dracaena draco is native to subtropical arid area of Macaronesia. Horizontal precipitation is an important component of water balance in such arid and semiarid areas. Morphological, anatomical and physiological adaptations to drought stress and demonstrated ability to absorb condensed water on the leaves into the stem tissues were discovered at D. draco. The aim of performed measurements was to quantify the importance of horizontal precipitation as an additional source of moisture during the critical period of juvenile stages of D. draco in Anaga (Tenerife). Measuring sets based on lysimeters measured the weight changes of seedlings placed in flowerpots hanging on the weights. The results of measurement proved that the seedlings can partly replace loss of water from evaporation by the water uptake from the atmosphere. Water uptake from the atmosphere took place mainly at night and the water output by transpiration predominated during the day. Horizontal precipitation replaced the evaporation by 6 to 10 % in the first period measured from October and did not replace the evaporation in the second period of measurements that started in January

Puertos Francos on Canary Islands
Rohrová, Eliška ; Křížová, Markéta (advisor) ; Binková, Simona (referee)
This diploma thesis focuses on the Canary Islands special arrangements in taxation in the context of the international trade since the end of the 18th century, which were related to their unique physiographical and socio-economical conditions. Long- term calling of a local society for a taxation which could lead the islands from a deep economic crises of the first half of the 19th century and spreading the idea of liberalism in international trade, culminated in declaration of Puertos Francos in 1852. Granting of Puertos Francos led to closing of customs houses and abolition of some duties connected with the foreign exchange. Thanks to the new system of taxation, by the turn of the 18th and 19th century, the Canary Islands became an important junction of the international trade and attracted interest of colonial empires, which used the islands as a starting point of the trails to their overseas territories.

Hodnocení krajinného rázu ostrovů Gran Canaria a Fuerteventura
Nevrlá, Stanislava
This work is studying the development and actual situation of landscape in Canary Islands with focusing on islands of Gran Canaria and Fuerteventura. The specific geologic and climatic conditions with huge impact of human activity and tourism started to change the landscape radically. First part contains analysis of the geographical, geological and nature conditions of all seven Canary Islands and the process of colonisation through the boom of tourism and its impact to the landscape. Second part of the study is focused on measures how to preserve the original character of the landscape in coordination with development of tourism and economic activity. The work also contains an application of the assessment method of larger areas created by Ing. Roman Bukáček.
