| 摘 要： | 我们利用标准化调查和广泛调查两种方法对尼日利亚西南部森林中黑猩猩(Pan troglodytes)的分布状态进行了调查。本研究确认该地区总计2 443·58 km2的15个森林保护区内存在该物种。然而基于间接证据,该地区之前仅有8个森林保护区共计1 920·48 km2被调查过。我们将独立收集的年度数据根据不同保护区进行分类总结并且估计了建巢黑猩猩的个体密度。研究结果显示该地区的黑猩猩呈低密度高分散分布,其中只有Eba和Ise两个森林保护区中黑猩猩的分布密度显著大于0·20/km2。研究区域内四个森林保护区中黑猩猩的建巢数大于10 (Akure/Ofosu森林保护区,13个; Oluwa森林保护区, 11个;Ise森林保护区22个; Ago-Owu森林保护区,11个)。此外,在Ise森林保护区内我们观察到黑猩猩其它活动(例如观望行为,发声行为,取食迹象和粪便)的频次显著高于其它森林保护区。研究结果表明,残余且易于管理的黑猩猩种群分布于该调查区域。建议采取适当的保护措施来保证它们的继续生存

| Abstract: | The status and distribution of chimpanzee Pan troglodytes populations were investigated in the humid forest of southwestern Nigeria. Fifteen forest reserves totaling 2 443.58 km~2 were identified to harbor the animal in the region, and eight of these, with a total area of 1 920. 48 km~2 were surveyed. The density of chimpanzees was greater than 0.20 km~ -2 in only two forest reserves; Eba Forest Reserve and Ise Forest Reserve. Numbers of nests sighted were observed to be above ten in four of the reserves; Akure/Ofosu Forest Reserve 13, Oluwa Forest Reserve 11, Ise Forest Reserve 22 and Ago-Owu Forest Reserve 11. Other signs of chimpanzee presence, such as direct sightings, vocalizations, feeding signs and feces were more frequent in the Ise Forest Reserve. These results suggest that remnant manageable populations of chimpanzees still exist in the region and that there is the need to initiate conservation polices that will guarantee their continued existence in Southwestern Nigeria. |
