Keeping and breeding of CITES reptiles in Czech Republic
 TRINHOVÁ, Leona
Czech Republic considerably participated on European terraristic history with breeding of many reptiles and amphibians.This thesis covers breeding of reptiles protected on Czech Republic territory by CITES agreement. Based on mapping performed by zoological gardens, other specialized facilities and private breeders, percentage graphs were created for both reptiles not bred in Czech Republic, those bred by terrarists so far without successful reproduction and also for reptiles successfully reproduced. Aim of this thesis was to find outbreeding level of endangered reptiles within Czech Republic.Graphs with breeding success results were created for each genus. It was discovered that the best breeding results exist for reptiles reared most commonly here; turtles are bred less successfully and the least percentage of success was found with crocodiles. Probable reasons for such results were clarified too.

The possibilities of determining the geographic origin of plant and animal products by means of stable isotopes of oxygen, hydrogen and carbon. Isotope signature in keratin of tortoise´s shell
 DRTINOVÁ, Martina
This biological study is focused on the possibility of using stable isotope analyses to determine the geographic origin of plants and mainly animals especially tortoises. In the experiment nineteen tortoises were divided into two groups which were fed by isotopically different food and water for one year. The samples of keratin from their shells were collected before and after the experiment. Then the samples were analysed for the ratio of particular isotopes using isotope ratio mass spectrometry.
