For this thesis I conducted a study on the subspecies of the common wall lizard, Podarcis muralis maculiventris, that only lives in Tyrol within Austria. From March to October 2011 I observed and documented the density, spatial preferences, behaviour and morphology of a wild population in the Alpenzoo Innsbruck. The data was collected using different methods: 89 standardized tours through the zoo at different times of the day over the whole observation period provided the data for the structure, the density and spatial preferences of the population. With standardized protocols I obtained various habitat parameters to determine the habitat preferences. The behaviour, diurnal patterns of activity and the usage of different substrates were explored using the method of focal animal samplings. In addition to this I caught, measured and marked 69 animals. The maximum number of observed animals on a single tour was 98, however taking into account the maximum observation on smaller areas, the population adds up to approximately 177 lizards. The ratio of juveniles to adults was on average 1:3. In total I calculated a population density of around 5 Ind./100m in the observation area. The denser populated sections were characterized by lots of rocks, enough hiding places, a high percentage of near-ground vegetation and a highly structured relief. The number of sighted animals was strongly influenced by the temperature of the substrate The substrate temperature had also a strong positive impact on the activity of the animals. The colouring of the common wall lizards in the Alpenzoo Innsbruck was grey/brown to green. The ventral shadings ranged from white to a darker orange and sometimes individuals had blue lateral stripes. On average the examined individuals had a total length of 16 cm (snout-vent length: Ø 6,6 cm, tail length: Ø 9,5 cm) and weighed 5,9g. It was not possible to determine clear gender differences in this population.
