“…On the other hand, female specimens of L. media have higher mean age compared with those male specimens. Findings of L. viridis show similarity to the L. agilis that reached maturity at 2 years, while females attained at the third year of their lifetime (Candan, 2021; Guarino et al, 2010), like in Daghestan specimens of same species (Roitberg & Smirina, 2006a). Similarly, Schreiber's green lizards have been reported to reach maturity at the age of 3 years (Luís et al, 2004).…”

“…It was estimated that individuals of the L. media live up to 10 years, whereas both sexes of L. viridis live for 8 years. Contrarily, males and females of the congener Lacerta agilis have lifespan of 7 and 8 years, respectively (Candan, 2021; Guarino et al, 2010; Roitberg & Smirina, 2006b). Similarly, the minimum longevity for Iberian Emerald Lizard, Lacerta schreiberi has been reported to be 7 and 8 years by Luís et al (2004) for males and females, respectively.…”

“…Although the age structure of many lizard species has been revealed by skeletochronology, studies on the demographic structure of the genus Lacerta are limited (Candan, 2021; Guarino et al, 2010; Kalaycı et al, 2018; Odabaş et al, 2019; Roitberg & Smirina, 2006b). Furthermore, neither of these investigations addressed the L. media nor the L. viridis species.…”

Determining the age of any species allows it to be analyzed from the ontogenetic, demographic, and ecological perspectives. In the present study, we tested the hypothesis that the age structure of congener species (Lacerta media and Lacerta viridis) with the same ecological niche may vary in different areas. In this context, we applied skeletochronology method to reveal various demographic parameters, such as age structure, longevity, age at sexual maturity, growth rate, survival rate, adult life expectancy, and the relationship between age and body size in the green lizard, L. viridis, and the medium lizard, L. media. In L. media and L. viridis, the maximum lifespan was 10 and 8 years, respectively. The mean age and body size of females were significantly greater than those of males in L. media. However, in the examined L. viridis population, no appreciable variation in mean age or body size was found to exist between the sexes. It was estimated that the green lizards reach maturity at the age of 2 or 3 years. However, the L. media reached sexual maturity approximately 1 year later than the congener. The body size markedly increased with age in males for both studied populations. However, in females, body size positively increased with age only in L. media. The approach of skeletochronology that we utilized in this study to assess age structure makes it simple to gather a variety of time-dependent ecological data for such ectothermic species.

“…4). In reptiles, body length correlates to age due to an undetermined growth throughout their life (Candan 2021). Indeed, assuming 325 mm as SVL at sexual maturation (Lucchini et al 2020;Espasandín et al 2022) we indicate that helminths were mostly found in adults of V. seoanei.…”

Helminth fauna and some biotic and abiotic traits were analysed in Iberian adder Vipera seoanei (Squamata: Viperidae) a European viper nearly endemic to northern Iberian Peninsula, in an attempt to confirm previous claims of relationships between this ecological traits in this genus. A total of 317 samples mostly covering the distributional range of V. seoanei, were examined. Compared with other Vipera species from the Iberian Peninsula, the helminth fauna is also impoverished in V. seoanei, but it is contrary to other Vipera species from Central and East Europe. Helminths were mostly found in adult vipers, and occurred in vipers located at the periphery of the species range, characterised by low elevation, high temperature and precipitation levels, and abundant pastures.

Do sexual differences in life strategies make male lizards more susceptible to parasite infection?

Female and male hosts may maximise their fitness by evolving different strategies to compensate for the costs of parasite infections. The resulting sexual dimorphism might be apparent in differential relationships between parasite load and body condition, potentially reflecting differences in energy allocation to anti‐parasitic defences. For example, male lacertids with high body condition may produce many offspring while being intensely parasitised. In contrast, female lacertids may show a different outcome of the trade‐offs between body condition and immunity, aiming to better protect themselves from the harm of parasites. We predicted that females would have fewer parasites than males and a lower body condition across parasitaemia levels because they would invest resources in parasite defence to mitigate the costs of infection. In contrast, the male strategy to maximise access to females would imply some level of parasite tolerance and, thus, higher parasitaemia. We analysed the relationship between the body condition of lizards and the parasitemias of Karyolysus and Schellackia, two genera of blood parasites with different phylogenetic origins, in 565 females and 899 males belonging to 10 species of the Lacertidae (Squamata). These lizards were sampled over a period of 12 years across 34 sampling sites in southwestern Europe. The results concerning the Karyolysus infections were consistent with the predictions, with males having similar body condition across parasitaemia levels even though they had higher infection intensities than females. On the other hand, females with higher levels of Karyolysus parasitaemia had lower body condition. This is consistent with the prediction that different life strategies of male and female lacertids can explain the infection patterns of Karyolysus. In contrast, the parasitaemia of Schellackia was consistently low in both male and female hosts, with no significant effect on the body condition of lizards. This suggests that lizards of both sexes maintain this parasite below a pathogenic threshold.
