贵州雷公山地区爬行动物调查研究

A Survey of Reptiles in the Leigongshan Mountain

本文记录了雷公山地区历次调查采集的爬行动物56种和亚种及发现的新种和新记录,阐明这一地区的爬行动物区系以华中区种和华南区种为主体。文中还描述了4种稀有蛇类的形态变异和11种21号蛇类标本的生殖腺解剖,分析了8种18号蛇类的食性,讨论了雷公山、梵净山和宽阔水的年均温和年均降水量与爬行动物区系成分间的关系.同时计算了这三地区间爬行动物种类的相似系数。

56 species and subspecies of reptiles (280 specimens) belonging to 33 genera,8 families and 3 orders were collected from the Leigongshan Mountain in a herpetological survey From April to May of 1985,of which 3 species have been found to be new records in the Leigongshan Mountain.They are Ptyas mucosus (Linnaeus),Naja naja (Linnaeus),Achalinus ater Bourret.On the basis of the survey,the central and southern Chinese elements are the dominant faunal component.The morphology variations of 4 species of the rare snakes have been described.They are Calliopis rnacclellandi (Reinhardt), Pareas hamptoni (Boulenger),P.Stanleyi (Boulenger) and Natrix boulengeri Gressitt.Reproductive glands of 21 specimens of 11 species have been an- atomied and food patterns of 7 species of snakes have been analysed.The relationship between reptile faunal components and average annual temper- ature and average annual waterfall quantity among Leigongshan Mountain, Fanjingshan Mountain and Kuankuoshui has been compared and analysed. The similar degrees of the reptiles between the same three mountains have been calculated with s(?)rensen similarity figure.
