虎斑颈槽蛇多态与变异

目的研究虎斑颈槽蛇大陆亚种Phabodophis tigrinus lateralis (Berthold)]在不同分布地区存在的多态现象和变异性。方法在分析已经报道的有关文献的基础上，研究辽宁、吉林等地野外采集到的标本，并对虎斑颈槽蛇大陆亚种的色斑变异和腹鳞的多态现象进行相关分析结果虎斑颈槽蛇大陆亚种的腹鳞数目与纬度呈强正相关，与经度呈中等正相关，与年均温度呈强负相关，与体长呈弱相关关系，年均温度高产卵时间早，而孵化时间长。结论分布范围相对较窄的蛇腹鳞数目是相对稳定的，分布范围广、跨越纬度大，腹鳞的数目差异亦很大。

Polvmorphism and Variation of Rhabdophis tigrinus lateralis

Objective To study the existing phenomenon and variability in different distribution about Rhabolophis tigrinus lateralis Methods On the base of the document which had been reporten,Study the sample that gathering from liaoning Jilin,analy the variation of the snake's stain and the phenomenon of the abdominal sclerite's polymorphism Result Amount of the snake's abdominal sclerite assume power plus interrelated to latitude;middling plus to longitude;power minus to annual average temperature;weak interrelated to length If the annual average temperature raise,it will advance the spawning period and prolong the hatch time Conclusion The abdominal sclreite amount will stable in narrow distrbution,difference in wide distribution and span
