Abstract:

To explore the population size and distribution of François’ Langur (Trachypithecus francoisi) in the Jinfo Mountain National Nature Reserve, as well as their adaptability to the environment, we conducted from December 2021 to October 2022 interview surveys, infrared observation, line observation, and trace observation methods. Feces samples of T. francoisi in the reserve were also collected using a non-invasive sampling method to assess gut bacterial composition. The results showed that there were about 180 T. francoisi in the reserve, with an average of 7.83 monkeys per group. Individuals were concentrated in the core area of the reserve, with the largest number in Longtang and Diaozui areas. The dominant phyla of fecal microbial flora in T. francoisi were Firmicutes, Actinobacteria, Verrucomicrobia, Bacteroidetes, and Proteobacterial. At the species level, Akkermansia muciniphila was the most abundant. In conclusion, the population size of T. francoisi in Jinfo Mountain National Nature Reserve has gradually increased recently, and gut bacterial diversity provided guarantees for the survival of T. francoisi in a complex natural environment.

摘要:

为了探究金佛山国家级自然保护区内的黑叶猴种群数量和分布情况,以及猴群对环境的适应性,本研究采用访问调查、红外相机监测、样线调查、痕迹观察等方法于2021年12月至2022年10月调查了金佛山国家级自然保护区内的野生黑叶猴 (Trachypithecus francoisi) 种群数量与分布。同时通过非损伤性取样法采集保护区内黑叶猴粪便并进行肠道微生物测序。结果表明,金佛山国家级自然保护区内有野生黑叶猴23群共约180只,平均7.83只/群,猴群集中分布于保护区的核心区,龙塘、吊嘴一带数量最多。金佛山黑叶猴的粪便微生物菌群中优势门类为厚壁菌门 (Firmicutes)、放线菌门 (Actinobacteria)、疣微菌门 (Verrucomicrobia)、拟杆菌门 (Bacteroidetes)、变形菌门 (Proteobacteria),在种水平上,嗜粘蛋白阿克曼氏菌 (Akkermansia muciniphila) 更具优势。结果得出,近年来金佛山国家级自然保护区内的野生黑叶猴种群数量呈现稳步上升趋势,其肠道微生物多样性为野生黑叶猴在复杂的自然环境中生存提供了保障。
