Morphological and reproductive traits of the insular population of Podarcis siculus (REPTILIA: LACERTIDAE) from Krk Island (Croatia)

Today, lizards of the genus Podarcis are one of the most important representatives of Mediterranean herpetofauna, primarily because of their great variability in islands. We studied a population of Podarcis siculus (REPTILIA: LACERTIDAE) from Krk Island (Northern Adriatic) and compared the results to other lacertid species of the Mediterranean Basin. The study was carried out using live lizards that were maintained in terrariums under natural conditions of light and temperature, where they produced egg clutches which were incubated until hatching. The eggs were incubated for average of 31 days and hatching took place from late July to mid of August. The average adult female body size (SVL) was 61, 88 mm. Out of 10 females, 9 produced egg clutches with average of 5.3 and the maximum of 7 eggs. The knowledge of reproductive potentials and life traits of this species is significant for further monitoring plans of this invasive species in these areas.
