We observed 18 groups of golden-cheeked gibbons (Nomascus gabriellae) in the secondary lowland forest in Cat Tien National Park from January 2004 to December 2005 to obtain information about the social organization of this little-studied species, in an area where the population is recovering through increased protection and forest regeneration. DNA from faecal samples of 10 infants and juveniles identified 1 case of extrapair paternity. DNA from faecal samples of 18 adults from three communities revealed the majority of adults sampled of both sexes to be related to adults in neighbouring territories. Overall, the indications are that in this empty habitat, gibbons appear to be able to establish territories adjacent to those of their kin.
2004年1月至2005年12月期间，我们在吉仙国家公园的次生低地森林中观察了18群黑冠长臂猿（白颊长臂猿），以获取有关这种鲜为人知的物种社会组织的信息。该地区的种群数量通过加强保护和森林再生正在恢复。对10只幼猿和亚成体粪便样本的DNA分析确定了1例配偶外父权情况。对来自三个群落的18只成年猿粪便样本的DNA分析表明，所采集的大多数成年雌雄猿都与相邻领地的成年猿有亲缘关系。总体而言，有迹象表明，在这片空旷的栖息地中，长臂猿似乎能够在其亲属的领地附近建立自己的领地。
