Spatial orientation in reptiles focused on methods of testing of allothetic navigation
Voňavková, Monika ; Landová, Eva (advisor) ; Telenský, Petr (referee)
Recently are known several different navigational systems in reptiles, mainly large scale navigational abilities based on sun and magnetic compass. The turtles are frequently used species in studies of spatial cognition, however, informations about spatial cognitive abilities in snakes and lizards (order Squamata) are only a few. Current knowledge concerning mechanism of small scale navigation based on allothetic orientation in snakes and lizards is only poorly understood. Aim of this thesis is review the literature about the mechanisms of reptile spatial orientation focused on allothetic navigation (using of external landmarks). As extension of this thesis is review of the principles of testing allothetic orientation in other groups (e. g. mammals) that were frequently used as a subject for testing allothetic orientation). The design of tests of allothetic orientation in model species of lizards (Eublepharis macularius) is one of the results of this thesis. Keywords: reptiles, spatial orientation, allothetic navigation

Testing of spatial orientation in leopard gecko ( Eublepharis macularius)
Voňavková, Monika ; Landová, Eva (advisor) ; Svoboda, Jan (referee)
The ability of the spatial orientation of the reptiles is not fully researched yet. It is unknown if reptiles use only simple types of navigation, for example cue learning (one key mark), or more difficult types, for example allothetic navigation (combination of marks) or cognitive map (mental representation of the area). The main aim of this thesis was examine the possibility of the spatial orientation in lizard leopard gecko (Eublepharis macularius) in modificated Morris water maze (MWM). Design of the experiments was based on Parallel Map Theory, a theory which describes using spatial information from more navigation frames. The leopard gecko preferences of orientation frames were tested . That means the ability to combinate the spatial information from the bearing maps (one mark and gradient) and the sketch maps (local marks). This ability is prerequisite for creating the integrated map. The research was also focused on the significance of the simple cue learning strategy and cognitive more difficult allothetic navigation for the orientation of leopard gecko. Leopard geckos can use the combination of information from the navigation frames, which indicate the possibility of integrated map creation. Usage of navigation strategies is individual.
