Parental behavior and recognition of juveniles in geckos of genus Teratoscincus
Suchomelová, Petra ; Frynta, Daniel (advisor) ; Kubička, Lukáš (referee)
4 ANNOTATION The diploma thesis deals with parental behavior and recognition of youngs by two kinds of desert geckos of genus Teratoscincus, specifically T. scincus and T. keyserlingii. The geckos inhabit a very extreme environment where it is not easy to survive, especially for the small hatchlings. Therefore, it is probable that small hatchlings live together with their parents in their territory for some time. If the parents tolerated them inside their territory, they would provide them with an indirect form of parental care. In the first part of the thesis the hypothesis that adults tolerate to the presence of juvenile conspecifics and heterospecifics (Eublepharis macularius) was tested. The main goal was to determine whether adults tolerate juveniles generally or whether they recognize juveniles conspecifics. To support the hypothesis of the adults' tolerance of juveniles the eggs of the adult geckos living in pair were left in their terrarium until the hatching of the juvenile. Further, the reaction of adult geckos to the presence of a E. macularius juvenile (small), admitted into the terrarium, was tested. The aim was to find out whether the two kinds of geckos, preying other geckoes in the nature, show predatory behavior toward the E. macularius. The standard experiment was carried out in the second...

Kováčiková, Ivana
The bachelor thesis Aspects of the Reproduction of the African Bush Elephant (Loxodonta africana) in the Wilds and in Captivity deals with the reproduction of the African bush elephant (Loxodonta africana) and various issues affecting it. The text focuses on the collection, study and assessment of literature related to the reproduction of the African bush elephant living in the wilds and in zoological gardens. It also points out the importance of the development and support of the reproduction of the African bush elephants, for the amount of the animals still living in the wilds is decreasing. The first part describes the general characteristics of the African bush elephant. Its subparts deal with zoological classification, evolution, anatomy, diet and communication system. The following part focuses on the reproduction of the animals and the related social behaviour thereof. The text further elaborates on musth, heat, mating, gravidity and birth, as well as on the development of the young after they are born. The thesis concludes with the evaluation of the current state of breeding of the African bush elephant in captivity and issues related to it.
