大兴安岭南麓东北马鹿 种群遗传多样性分析.

Due to the disturbance of human activities and changes in the natural environment, the survival of red deer (Cervus elaphus xanthopygus) is facing many problems. To understand the current status of the genetic diversity of red deer and to provide a basis for assessing the health status, we evaluated the genetic diversity of red deer in the Gaogesitai-Hanwula National Nature Reserve in the southern of the Greater Khingan Mountains in Inner Mongolia using mitochondrial Cyt b and microsatellite markers. Results showed that 246 fresh feces belonged to 182 individuals. Microsatellite makers showed that the average expected heterozygosity (He) was (0. 729±0. 016), and the average observed heterozygosity (Ho ) was (0. 768±0. 029). Mitochondrial marker showed that the haplotype diversity (Hd ) was (0. 347±0. 035), and the nucleotide diversity (Pi) was (0. 248±0. 025)%. There was a large proportion of rare haplotypes (33. 33%) in this population. Overall, the population genetic diversity of red deer in this region was at a low to medium level. Therefore, to avoid the risk of genetic diversity decline in the future, it is recommended to strengthen the management and protection of red deer in this region, and there is a need to promote gene exchange with red deer individuals in neighboring regions.
