 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Morphometric Analysis of Three Draco Lizard Species (D. blanfordii, D. maculatus, and D. taeniopterus) (Squamata: Agamidae) from Thailand) ผู้เขียน: Nattawut Srichairat,  ดร.พัฒนี จันทรโรทัย, รองศาสตราจารย์ , ดร.ประทีป ด้วงแค, รองศาสตราจารย์ , ยอดชาย ช่วยเงิน สื่อสิ่งพิมพ์:pdf AbstractTwo hundred sixty-seven preserved specimens of three Draco lizard species from Thailand consisting of D. blanfordii (17 females and 70 males), D. maculatus (58 females and 79 males) and D. taeniopterus (13 females and 30 males) were examined using 21 morphometric characters and 25 character ratios to assess morphometric differences. The results of univariate analysis showed that there were 12 morphometric characters and 2 character ratios that can be used for discrimination of the three Draco species regardless of sexual differences. Among these three species, it was found that 13 morphometric characters and 7 character ratios and 15 morphometric characters and 8 character ratios can be used to discriminate female and male lizards, respectively. The results of cluster analysis produced a dendrogram of the relationships among the three species and revealed that the three Draco species were divided into two morphometric clusters at a level of 0% of information remaining in which the D. blanfordii cluster was distinctly different from the D. maculatus and D. taeniopterus cluster. |
