Comparison of the body size and age structure of Lebanon lizard, Phoenicolacerta laevis (Gray, 1838) at different altitudes in Turkey
(Senckenbergische Naturforschende Gesellschaft, 2018) Üzüm,N.; Ilgaz,Ç.; Avci,A.; Candan,K.; Güler,H.; Kumlutaş,Y.
In this study, comparison of a life history traits (e.g. body size, age at maturity, longevity) of two populations of Phoenicolacerta laevis from different altitudes is being carried out (Anamur, 22 m a.s.l.; Andirin, 1.083 m a.s.l.) for the first time. We applied phalangeal skeletochronology to obtain the age of juveniles and adults. Age was determined by counting the lines of arrested growth (LAGs) in cross-sections. Males in both populations were the larger of the two sexes and a male biased sexual dimorphism was determined for both populations. Body size (SVL) was similar in both sexes and populations. Age of maturity was calculated to be 3 years of age for males and females in both populations. The average age of males and females was calculated as 6.62 ± 0.37 (Mean±SE) and 6.11 ± 0.26 years in Anamur, and 6.15 ± 0.51 and 5.26 ± 0.24 years in Andirin. There was statistically significant variation between sexes, but no significant difference in populations was found in relation to age. For both populations, a significant positive correlation was found between age and SVL in males and females. © Senckenberg Gesellschaft für Naturforschung, 2018.

Electrophoretic comparison of blood-serum proteins of Apathya cappadocica (Sauria, Lacertidae) subspecies from Anatolia
(2010) Ilgaz,C.; Arikan,H.; Kumlutaş,Y.; Avci,A.
Blood-serum proteins of the known subspecies of Apathya cappadocica (Werner, 1902) were studied comparatively by polyacrylamide disc gel electrophoresis. In order to obtain useful biochemical data for classification, differences between the electrophoreograms of the samples included in the morphologically different subspecies were distinguished qualitatively and quantitatively. These comparisons indicated that electrophoretic results supported morphological discrimination of the known subspecies of A. cappadocica. © Firenze University Press.

External morphology and osteology of darevskia rudis (Bedriaga, 1886), with a taxonomic revision of the Pontic and small-caucasus populations (Squamata: Lacertidae)
(Magnolia Press, 2013) Arribas,O.; Ilgaz,Ç.; Kumlutaş,Y.; Durmuş,S.H.; Avci,A.; Üzüm,N.
A broad sample of Darevskia rudis from the main part of its range was reviewed with regard to external morphology (dis-criminant, UPGMA, MST and ANOVA analyses) and osteology. Darevskia bithynica is raised to species rank, with two subspecies: D. b. bithynica and D. b. tristis. The other subspecies are fairly similar (D. r. rudis being the most different). Two singular populations are described as subspecies: D. r. mirabilis ssp. nov. from Kaçkar Mountains, geographically adjoins the otherwise different D. r. bischoffi and D. r. bolkardaghica ssp. nov., which is geographically isolated but that seems to be very closely related to D. r. obscura.
