摘要

The only population of reindeer ( ) in China,herded extensively by the Ewenki people, is the most southern population in the world.Genetic diversity plays a key role in the survival of endangered reindeer. Tosystematically understand the genetic variability of reindeer in China, 163 individualsfrom 8 populations were analyzed using 11 microsatellite loci. A total of 85 alleles weredetected and the average number of alleles per locus was 7.7. The observed heterozygosityand expected heterozygosity ranged from 0.3736 to 0.5299 and from 0.6491 to 0.7608.Hardy-Weinberg equilibrium analysis indicated that a de ciency of heterozygotes existed inall eight populations. Both the ST and AMOVA analyses showed a low levelof genetic di erentiation among populations. UPGMA dendrogram revealed that population SYLformed one cluster, separating from the other populations. Then the GWQ and YSHpopulations formed another cluster and clustered with the BDX, BLJY, DML, DW and MLYSpopulations. Increasing the current exchange rate of reindeer among different populationsand establishing natural reserve may be the e ective approaches to conserve the fragilereindeer populations in China
