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...
