北京松山国家级自然保护区野猪种群遗传结构初步分析
Genetic structure analysis of wild boar population in Beijing Songshan National Nature Reserve
摘要
Abstract
With the gradual improvement of the natural ecological environment in Beijing,the population of wild boar(Sus scrofa)continues to grow,causing local damage.Understanding the background of the wild boar population genetic structure helps formulate long-term control measures.In this study,we used non-invasive sampling and PCR amplifica-tion techniques to analyze the sex structure of the wild boar population in Beijing Songshan National Nature Reserve,and microsatellite molecular markers to analyze the genetic diversity and genetic distances to understand the future devel-opment trend of the population.The results showed that 42 individuals were identified from 88 suspected wild boar fecal samples,of which 35 were females and 7 were males,with a sex ratio of 5∶1.The analysis showed that the genetic polymorphic information content(PIC)of the population was in the range of 0.55-0.81,with an average of 0.71,and the population had moderate genetic diversity.An evolutionary tree was constructed based on genetic distances between microsatellite loci,and the 42 individuals showed three main branches.The results of the clustering analysis also showed that the individuals of this population were clustered according to the three genetic clades.In general,the wild boar population in the Songshan area has a certain degree of segregation in terms of genetic structure,but it has not reached the level of obvious differentiation and still belongs to the same population.In addition,the analysis of the in-breeding coefficient showed that the Songshan wild boar population was moderately inbred in general,which would have a certain inhibitory effect on population growth.This study provides basic information for understanding the genetic structure of wild boars in the study area and is an important reference for estimating the changes in population density and predicting the development of wild boar populations in this area.关键词
