Abstract (AI)
We assessed age and first reproduction age in Salamandrina perspicillata females by means of skeletochronological analysis. As we examined sections from the third toe of the hind limbs, the tecnique herewith introduced is non-letal and compatible with ecological investigations. Females reached sexual maturity at four or five years; the oldest female was 12. SVL is a reliable body size index for assessing age (r2 = 0.74).
Key Findings
1
Female Salamandrina perspicillata reached sexual maturity at four or five years of age.
2
Skeletochronological analysis of third-toe sections provided a non-lethal method for estimating age in female Salamandrina perspicillata.
3
Snout–vent length (SVL) was a reliable body-size index for age assessment, with r² = 0.74.
4
The oldest examined female was 12 years old.
