We explored individual variation and asymmetry in the skull shape of the
common wall lizard (Podarcis muralis Laurenti, 1768) across four
populations representing different habitats, by employing geometric
morphometrics. We found directional and fluctuating asymmetry across the
analysed populations, without differences in fluctuating asymmetry among
populations. Patterns of individual variation and fluctuating asymmetry
were highly correlated within and among populations. Asymmetric skull
shape variation was similar in all populations, and was mostly related
to the jaw adductor muscle chamber. Our results imply that the uniform
pattern of skull fluctuating asymmetry results from a high level of
canalisation. Directional asymmetry can be related to anatomical and
behavioural lateralisation.
