title: Captive Breeding of Two Colubrid Species — &lt;i&gt;Zamenis situla&lt;/i&gt; and &lt;i&gt;Elaphe sauromates&lt;/i&gt; (Serpentes: Colubridae) and Their Reproductive Biology in the Crimea
abstract: Presented data on the reproductive biology of two poorly studied species of the colubrid snakes of the Crimean fauna (Leopard snake, Zamenis situla; Blotched ratsnake, Elaphe sauromates) are based on the experience of their captive breeding and observations in nature. Reproductive characteristics of the both species in different parts of their ranges are compared.
