Abstract

The endangered François’ langur (Trachypithecus francoisi) is only found from southern China to northeastern Vietnam. This study evaluates behavioral differences between provisioned (Ts, 7 individuals) and wild (Tn, 13 individuals) family groups in Mayanghe National Nature Reserve, China. Scan sampling every 5 min for 12 h daily between the months of March 2013 and February 2014 was used to record behaviors in seven categories. Tn exhibited three main feeding periods daily, whereas Ts showed more variable behavioral patterns that relied on provisions. The Tn alpha male showed twice the amount of guarding behavior compared with the Ts alpha male. The proportion of each habitat type utilized differed significantly between Tn and Ts (χ2[4] = 17,131.4, p < 0.01). Additionally, dietary diversity differed between the two groups: Tn fed on 61 plant species, whereas Ts fed on 43 plant species. Tn rarely ate sweet potato and corn other than discarded remnants of human food (0.2% of their total food sources), whereas these foods represented 21.8% of Ts food sources. We compared data for the two troops to understand this species’ activities under human interference, in particular to determine whether provisioning is a suitable strategy for their conservation.

马扬河国家级自然保护区François‘Langur（Trachypithecus francoisi）种群与野生种群活动预算、饮食和栖息地利用的比较

濒危的弗朗索瓦叶猴（Trachypithecusfrancoisi）只在中国南部到越南东北部发现。本研究评估了中国马扬河国家级自然保护区供应（Ts，7个个体）和野生（Tn，13个个体）家庭群体之间的行为差异。在2013年3月至2014年2月期间，每天12小时，每5分钟进行一次扫描采样，用于记录七类行为。Tn每天表现出三个主要的进食期，而Ts表现出更多依赖于食物的可变行为模式。与Tsα雄性相比，Tnα雄性表现出两倍的保护行为。Tn和Ts利用的每种生境类型的比例差异显著（χ2[4]=17131.4，p<0.01）。此外，两组之间的饮食多样性也存在差异：Tn以61种植物为食，Ts以43种植物为生。Tn很少吃红薯和玉米，除了人类食物的废弃残渣（占其总食物来源的0.2%），而这些食物占Ts食物来源的21.8%。我们比较了这两支部队的数据，以了解该物种在人类干扰下的活动，特别是确定供应是否是保护它们的合适策略。
