摘要
麋鹿是我国Ⅰ级重点保护的濒危物种,野生种群于19世纪灭绝。北京麋鹿生态实验中心于1985年和1987年自英国乌邦寺共重引入的38只奠基个体经散放式放养后,种群的数量至今已超过了1000只(包括繁育子代外送至国内其他动物园或研究基地的数量)。为了探讨该重引入种群的遗传多样性,采用25个微卫星位点对北京麋鹿苑种群及浙江临安亚种群的167只麋鹿个体进行了群体检测,获得的每个位点的平均等位基因数为2.16,平均期望杂合度为0.370,平均多态信息含量为0.301。该结果表明,北京麋鹿苑种群及浙江临安亚种群麋鹿的遗传多样性较贫乏。因此建议与我国引自英国其他种群的麋鹿种群之间进行个体交流,从而增加各种群的遗传基因杂合度,以促进我国麋鹿的可持续发展。
Pere David＇s deer Elaphurus davidianus is one of the endangered species of China and is a nationally 1st tier protected species.The wild population of Pere David＇s deer（also known as milu deer）went extinct in the 19th century.In 1985 and 1987,the Chinese government re-introduced 38 milu individuals obtained from Woburn Abbey in the United Kingdom.These founders were released and bred in their own in Beijing Milu Park,and now,the population has exceeded 1000 individuals（including those offspring which have since been transferred to zoos and research facilities around China）.25 polymorphic microsatellite loci were used to analyses the genetic diversity of this re-introduction species based on 167 samples from two populations in China,namely Beijing Milu Park population and Zhejiang Lin＇an populations.The results showed that：the mean number of observed alleles per locus was 2.16,the average expected heterozygosity values was 0.370,and the mean polymorphisms information is 0.301.All these result indicates that the genetic diversity of two populations was poor.In order to promote sustainable development of milu populations,we should exchange milu individuals from other populations,such as from Dafeng milu population,to enhance the inheritance gene heterozygosity.
