WOS: 000334089600008Age and body size of 81 Stellagama stellio (syn. Laudakia stellio) specimens from five regions of Turkey were studied using skeletochronology. Lines of arrested growth (LAGs) in phalanges were used to estimate the age. Snouth vent length (SVL) ranged between 90.05 - 133.14 mm (mean: 109.58 +/- 10.26) in males and 86.24 - 130.43 mm (mean: 105.83 +/- 10.68) in females. Age ranged between 2-9 (mean: 5.34 +/- 1.63) in females and 3-10 years (mean: 5.72 +/- 1.82) in males. We did not observe any significant difference in terms of age and SVL between sexes. Intersexual differences in body size were male-biased (SDI =-0.03) but this relation was not statistically significant. A significant difference between the lowland (below 800 m) and mountain (above 800 m) populations was found in respect of SVL, with mountain individuals being larger than the lowland. A significant age difference between lowland and mountain populations was not found. A significant positive correlation was found between age and SVL both in males and females. Individuals reached maturity between 2 and 3 years
