【摘要】 The distribution pattern of reptiles in mountainous regions is generally related to altitude.The distribution of viperine species can be limited by elevation.Short-tailed viper snakes(Gloydius saxatilis) of South Korea are found mostly in high elevation mountainous areas,but few studies have evaluated how their distribution relates to elevation gradient.This study was conducted from 2012 to 2013 to investigate the altitudinal distribution of short-tailed viper snakes in mountainous areas and to discover their movement patterns in Cheon-ma Mountain County Park in South Korea.A translocation method utilizing radiotracking technology was employed to confirm whether their distribution was influenced by altitude.The results showed that most short-tailed vipers were observed in middle and high altitude areas(from 400 m to 800 m),but none were observed in low altitude areas(from 200 m to 400 m).According to the results of the translocation and tracking experiments,the individuals of the translocated group showed a significantly broader home range than those of the control group.In addition,all individuals of the translocated group moved vertically,while most of the control group moved horizontally.Therefore,all translocated individuals tended to move back toward their original habitat,a high elevation area.Consequently,we concluded that the distribution of short-tailed viper snakes was limited by altitude.
