Morphological variability of the Spurthighed Tortoise,Testudo graeca, in the Nemrut Volcano (Eastern Turkey)

Morphological variation among a population of Testudo graeca from two neighbouring sites of the Nemrut Volcano has been analysed, and six morphometric characters have been assessed in 305 specimens, mainly adults. This population shows remarkable morphometric differences. Macrohabitat differences among sites have been involved to explain this variability in the light of the huge morphological plasticity of this wide-ranging taxon.
