Türkiye’de Doğu Karadeniz Bölgesinden Toplanan Darevskia clarkorum (Sauria: Lacertidae: Darevskia) Örneklerinin Morfolojisi, Taksonomisi ve Dağılışı
Do¤u Karadeniz Bölgesi’ndeki alt› farkl› lokaliteden toplanan yüz üç Darevskia clarkorum (Darevsky and Vedmederja, 1977) örne¤i, pholidosis karakterleri, morfometrik ölçümler ve renk-desen özellikleri bak›m›ndan incelenmifltir. Tüm populasyonlara uygulanan Kolmogorov-Smirnov testi, Ortacalar ve Hemflin populasyonlar›nda ventralia enine karakteri bak›m›ndan efleysel dimorfizm oldu¤unu göstermektedir (P < 0,05). Mann-Whitney U testi sonuçlar›na göre, on alt› pholidosis karakteri bak›m›ndan populasyonlar aras›nda farkl›l›k söz konusudur (P < 0,05). Morfometrik ölçümlerin karfl›laflt›r›lmas› için, dört tane morfometrik indeks ve oran gelifltirilmifltir. Independent t-testi sonuçlar›na göre, erkek ve difliler aras›nda morfometrik indeks ve oran de¤erleri bak›m›ndan bir farkl›l›k yoktur. Dört morfometrik indeks ve orana dayanan tek-yönlü varyans analizi (ANOVA) testi populasyonlar aras›nda bafl indeksi, bafl-gövde uzunlu¤u / kuyruk uzunlu¤u ve kuyruk uzunlu¤u / total uzunluk karakterleri bak›m›ndan farkl›l›k oldu¤unu göstermektedir (P < 0,05). Alt› farkl› lokaliteden toplanan örnekler, pholidosis karakterleri (masseterik pla¤›n bulunma ve rostral-internasal pla¤›n temas etme yüzdelerinin yüksekli¤i d›fl›nda), morfometrik ölçümler ve renk-desen özellikleri bak›m›ndan literatürde Darevskia clarkorum için belirtilen söz konusu özelliklerle benzerlik göstermektedir. Ayr›ca türün Türkiye’deki da¤›l›fl sahas› geniflletilmifltir.
The Morphology, Taxonomy, and Distribution of Specimens of Darevskia clarkorum (Sauria: Lacertidae: Darevskia) Collected from Turkey’s Eastern Black Sea Region
In all, 103 specimens of Clark's lizard, Darevskia clarkorum (Darevsky and Vedmederja, 1977), from 6 localities in the eastern Black Sea region of Turkey were examined in terms of pholidosis characteristics, morphometric measurements, and color and pattern features. Kolmogorov-Smirnov testing across all populations verified sexual dimorphism in the Ortacalar and Hemşin populations, regarding transversal series of ventral plates (P < 0.05). According to the Mann-Whitney U test, 16 pholidosis characteristics showed differences among the populations (P < 0.05). For comparison of morphometric measurements, 4 morphometric indices and ratios were developed. According to the results of independent t-testing, no differences were found between males and females among the populations. One-way variance analyses based on 4 morphometric indices and ratios confirmed that head index, snout-vent length/tail length, and tail length/total body length showed differences among the populations (P < 0.05). Regarding pholidosis characteristics (except rates of the presence of a masseteric plate and contact between the rostral and internasal plate), morphometric measurements, and color and pattern features, the specimens collected from 6 different localities were similar to D. clarkorum specimens mentioned in the literature. Furthermore, the known range of the species in Turkey has been extended.
