Effects of Incubation Temperature on Duration of Incubation, Hatching Success, and Hatchling traits in The Gray Rat Snake, Ptyas korros (Colubridae)
孵化温度对灰鼠蛇卵孵化期、孵化成功率和孵出幼体特征的影响

The gray rat snake, Ptyas korros (Colubridae), is a kind of popular oviparous snake in the southern provinces of China. Herein, we established an experimental protocol using the gray rate snake as the animal model to examine (1) influence of temperature on hatching success, hatching time, (2) influence of temperature on hatchling traits, (3) influence of temperature on embryonic use of energy and material. In early July 1999, we collected 11 gravid females from a private ped...
