| The purpose of this study is to provide support for the conservation and utilization of roe deer population and to provide basic knowledge to find the effects of roe deer on Amur tiger and Amur leopard as their prey.During the period from January 2015 to January 2017,266 fecal samples of roe deer were collected in the northern region of Changbai Mountain for genetic research.The genetic diversity and sex-biased dispersion of 7 Siberian Roe Deer populations in Northeast China is analyzed using data from 10 microsatellite loci.The results show that the genetic diversity of 7 Siberian roe deer populations is relatively high.The number of alleles is from 7.3 to 11.1.The mean number of alleles is 8.9.The total allele richness is 7.5,which is also on a high degree.The values of HE and Horange from 0.7 to 0.76,indicating that the genetic diversity and the degree of variation of 7 populations are relatively high.Of the 7 populations,only the Fis value of Huangjihe population is negative(-0.01).The Fis values of the remaining 6 populations is>0,which are from 0.021 to 0.061,indicating that there may be a certain degree of inbreeding.Genetic diversity analysis shows that roe deer populations in the study area have good breeding and genetic potential,and can be used as germplasm resource for further sustainable utilization.Spatial autocorrelation analysis showed that the roe deer population in Wangqing area had significant spatial genetic correlation within the distance of 5?10 km.In the study of population genetic structure and sex-biased dispersal,spatial auto-correlation analysis shows that roe deer population in Wangqing has significant spatial genetic correlation within the distance of 5?10 km.It is suggested that the spatial genetic structure of roe deer population in Wangqing is the result of restricted gene flow.Genetic structure of roe deer populations in northern Changbai Mountain shows gender difference and pattern of female-biased dispersal,which may be caused by two reasons:1)Difference of winter habitat utilization between male and female roe deer.Females with fewer offspring need to migrate over longer distances in winter to return to natal area to join their own matriarchal group.2)The monogamy of roe deer and the mating strategies of males to defend their territory have led female roe deer to migrate over long distances to find and choose a mate with better resources. |
