Türkiye’deki iki farklı populasyondan Lacerta agilis’in LINNAEUS, 1758 (Reptilia: Lacertidae) vücut büyüklüğü ve yaş yapısı

Abstract

Türkiye'deki iki farklı popülasyondan Lacerta agilis'in 47 müze örneğinde (31 dişi ve 16 erkek) yaş yapısı ve yaşam süresi iskelet kronolojisi kullanılarak incelenmiştir. Cinsiyete bağımlı vücut büyüklüğü dişi eğilimli olmasına rağmen, erkeklerin ortalama SVL’si dişilerden önemli ölçüde farklı değildir. Yaş dağılımı erkek bireylerde 3 ile 6 yıl arasında, dişilerde ise 3 ile 8 yıl arasında değişmektedir. Erkekler iki, dişiler ise yaşamın üçüncü yılından sonra cinsel olgunluğa ulaşır. Yaş, cinsiyetler arasında önemli ölçüde farklılık göstermez. Bununla birlikte, yaş yapısı ve SVL iki popülasyon arasında önemli ölçüde farklı değildir. SVL ile yaş arasında Ardahan popülasyonu için zayıf bir korelasyon olsa da Kars popülasyonu için anlamlı ölçüde bir pozitif korelasyon vardır. Cinsiyetler göz önüne alındığında, Ardahan popülasyonunda SVL için, Kars popülasyonda ise yaş dağılımı için anlamlı bir fark söz konusudur.

Body size and age structure of Lacerta agilis LINNAEUS, 1758 (Reptilia: Lacertidae) from two different populations in Turkey

Abstract

Age structure and longevity in 47 museum specimens (31 females and 16 males) of Lacerta agilis from two different populations in Turkey were skeletochronologically studied. The mean SVL of males was not significantly different from those of females, although intersexual differences in body size are female-biased. The age structure ranged from 3 to 6 years in male individuals, and 3 to 8 years in females. Age at sexual maturity was 2 years for males, while females reached sexual maturity after the third year of life. The age did not significantly differ between the sexes. Additionally, age structure and SVL did not significantly differ between the two populations. A significant positive correlation between SVL and age structure was present for the Kars population, although there was a weak correlation for the Ardahan population. Considering sex, there was a significant difference in terms of SVL for the Ardahan population, while age structure significantly differed for the Kars population.
