pdf 05. Reproductive strategy in a montane population of the lizard Lacerta schreiberi (Sauria Lacertidae)

Abstract: The mountain population of Lacerta schreiberi studied at the Sistema Central (Spain) showed a narrow and highly synchronized reproductive period, adjusted to short periods of annual activity, that are characteristic of these Iberian areas. Adult females reached sexual maturity at a minimum age of four years. Only one clutch of eggs is laid per year. The average clutch size of 14 eggs was positively correlated with female body size. Clutch weight was high (25 to 56% of net female weight), and incubation time was long (65 to 1 1 0 days). During incubation eggs reached three times their initial weight. We found a noticeable variability in some reproductive characteristics during the three years under study and among individual females. The greatest phenotypic plasticity was in the size of the eggs, incubation time, and the size of hatchlings, while clutch size showed a higher stability in its average values.
