“…Skeletochronology, which is known as a very effective and reliable method, is used to calculate age by using presence of growth layers in the bone tissue and counting the lines of arrested growth (LAGs) in reptilian species (Castanet, 1994;Nayak et al, 2008;Guarino et al, 2010;Kim et al, 2010;Kolarov et al, 2010;Arakelyan et al, 2013;Kurita & Toda, 2013). For age determination of Turkish reptiles, a growing number of studies has been recently performed (Altunışık et al, 2013;Arakelyan et al, 2013;Tok et al, 2013;Gül et al, 2014Gül et al, , 2015Üzüm et al, 2014Kanat & Tok, 2015;Yakın & Tok, 2015).…”

In the present study, we investigated potential effects of some environmental climatic factors on life-history traits of twoDarevskia parvulapopulations located at different elevation sites and evaluated age, body size, SSD and growth rate results in these lizards. The age at maturity and longevity were found to be similar in both populations. Males of the highland population had significantly larger snout-vent length and older age than those of the lowland population. Although the mean ages of females were not significantly different between the two populations, the highland population had significantly larger snout-vent length than the lowland population. Considering all individuals (both males and females), we found that specimens from the population in the higher-elevation site had significantly larger snout-vent length and older age than those of the lower-elevation site. A low level of male-biased sexual size dimorphism was observed in both populations. The growth coefficient was lower in the high-elevation site than the lower elevation site. Growth rates were not significantly different between the populations. Our preliminary results indicate that although our studied populations were located at different elevation sites and had distinct climate, longevity, age at sexual maturity and growth rate results were similar. This may be a reason of the lower male-biased sexual size dimorphism in both populations.

“…Apart from different possible causes, this could be a result of continued growth as males and females spend their energy on reproducing more than growing after maturation (Kolarov et al, 2010). However, Yakın and Tok (2015) reported that females were larger than males in a study of A. anatolica from Çanakkale, Turkey, based on age structure. Even though both species belong to the same genus and A. danfordi is located at a higher altitude, the average SVL of female A. anatolica is bigger than that of A. danfordi while it is still similar in males (Table 3).…”

“…Juveniles are particularly needed to determine the certain age of maturity and to measure the asymptotic size in order to obtain precise results about this subject. Yakın and Tok (2015) reported that A. anatolica individuals need 3 years to mature. Each of our populations had different environmental conditions such as water resources.…”

The age and growth in two breeding populations of A. danfordi, inhabiting altitudes ranging from 678 m a.s.l. to 1200 m a.s.l. in Turkey, were investigated. The age differences between sexes were not statistically significant in either population. The mean age was calculated as 8.73 ± 2.12 and 8.33 ± 1.8 years in Kozan and 7.25 ± 1.58 and 5.78 ± 1.64 years in Saimbeyli for males and females, respectively. The age distributions of males did not statistically differ between populations, but females in Kozan were significantly older than those in Saimbeyli. The mean snout-vent length (SVL) difference between sexes was not significant in the Kozan population, whereas males were significantly longer than females in Saimbeyli. However, SVL was similar between the populations. Intersexual differences in body size were found to be male-biased for both populations. There was a positive and statistically significant relationship between SVL and age in both populations. This study examines the feasibility of the use of skeletochronology for A. danfordi. It also shows that these populations are getting older and this may endanger the future of A. danfordi in a warming world. Some life history parameters and population structures of A. danfordi are provided in this study but some questions still remain.
