Comparative morphology of the skin of Natrix tessellata (family: Colubridae) and Cerastes vipera (family: Viperidae).

We studied beneficial difference of the skin of two snakes. Two snakes were chosen from two different habitats and two families: Colubridae (Natrix tessellata) and Viperidae (Cerastes vipera). The investigations were performed by light and electron microscopy. Histologically, the skin of the studied species show pronounced modifications that correlated with functional demands. The scales in Nat...

Hypernatremia in Dice Snakes (Natrix tessellata) from a Coastal Population: Implications for Osmoregulation in Marine Snake Prototypes

The widespread relationship between salt excreting structures (e.g., salt glands) and marine life strongly suggests that the ability to regulate salt balance has been crucial during the transition to marine life in tetrapods. Elevated natremia (plasma sodium) recorded in several marine snakes species suggests that the development of a tolerance toward hypernatremia, in addition to salt gland de...

مطالعه فون مارهای شهرستان کنگاور در استان کرمانشاه و مقایسه جمجمه eirenis collaris با natrix tessellata

با توجه به غنای فون خزندگان شهرستان کنگاور و عدم وجود مطالعات دقیق بیوسیستماتیکی، این تحقیق به بررسی فونستیک مارهای شهرستان کنگاور در طی سال های 1394-1393 پرداخته است. نمونه های مار از منطقه جمع آوری شد و پس از شناسایی صفات متریک و مریستیک هر نمونه اندازه گیری گردید. بر اساس نتایج این تحقیق مشخص شد که در منطقه مورد مطالعه هفت گونه از شش جنس و چهار خانواده بودند. در بخش دیگر، جمجمه ی نمونه های ...
