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.
2005年11月，我们在中国广西西南部4个剩余栖息地片段中的3个（法、法乙和崇左）采集了白头叶猴的粪便样本，并使用5个微卫星基因座和SRY基因来评估46只叶猴在群体内部和群体之间的亲缘关系。我们观察到两种群体结构形式：单雄/多雌群体（OMGs）和全雄群体（AMGs）。法栖息地的一个全雄群体由两代组成，包括一位父亲、2个儿子和1个无亲缘关系的雄性，所有3个栖息地中的所有单雄/多雌群体都包括1只成年雄性、几只成年雌性和后代。在21个已确定的父子关系案例中，成年雄性作为单雄/多雌群体中的常驻雄性生育了20个后代（95%），而非常驻雄性生育了1个后代（5%），这表明成年雄性作为单雄/多雌群体中的常驻雄性在与雌性交配方面具有压倒性的优先权，而非常驻雄性也可能有机会采取秘密交配策略。
