摘要
We collected fecal samples of white-headed langurs from 3 of the 4 remaining habitat fragments(Fa,Fb and CZ)located in southwestern Guangxi,China in Nov 2005,and used 5 microsatellite loci and the SRY gene to assess the relatedness between 46 langurs within and between groups.We observed 2 forms of group structure:one-male/multi-female groups(OMGs)and all-male groups(AMGs).One AMG in Fa was composed of 2 generations,included a father,2 sons and 1 unrelated male,and all OMGs in all 3 habitats included 1 resident male,several adult females and offspring.Of the 21 identified father-offspring cases,the resident male fathered 20(95%)and the non-resident male sired 1(5%),suggesting that adult males had overwhelming priority of access to females as the resident male in an OMG,while the non-resident male may also have the opportunity to adopt surreptitious mating strategies.
