个人简介

严洁 女,汉族,1979年4月生,江苏盐城人,博士,副教授,中国动物学会会员、生物进化理论学会会员、两栖爬行动物学分会会员、江苏省动物学会会员。 1997-2001,南京师范大学生命科学学院,获学士学位; 2001-2006,南京师范大学生命科学学院,动物学专业,获博士学位; 2006-至今,南京师范大学生命科学学院,动物遗传资源研究所,讲师,副教授。

研究领域

从事两栖爬行动物的分子系统学和系统地理学研究。主要研究成果和正在开展的工作:结合线粒体和核ISSR标记,发现中国大陆的黑斑侧褶蛙种群中存在两个分歧明显的支系,推测华东地区和朝鲜半岛曾是该物种的冰期避难所;两大支系在中国东北的东辽地区发生了二次接触并存在渐渗基因流。对黑斑侧褶蛙支系间二次接触区的专项研究正在进行中;测定了四种蛇类的线粒体基因组全序列,结合系统发生树和线粒体基因组的基因排列,对蛇类线粒体基因组的进化过程进行了探讨,推测钩盲蛇线粒体基因组的基因排列为蛇类的祖先形式,自钩盲蛇支系分化后,发生了三种类型的重排
