在西藏红拉雪山自然保护区小场渡对野生黑白金丝猴亚群的食性和摄食生态进行了研究。该地区的气候比非人类灵长类动物居住的任何其他地区都要恶劣。黑白金丝猴以 25 种植物的 48 个部分、至少 3 种地衣和 7 种无脊椎动物为食。不同季节的食物种类差异显着，春季和夏季的饮食多样性最为丰富。在冬天，黑白金丝猴必须靠干草和树皮等备用食物生存。无处不在的地衣构成了全年的主要饮食成分，约占进食记录的 75%。尽管地衣是主要食物，但我们的研究结果表明，小场渡的猴子更喜欢以树叶为食，树叶的蛋白质含量比前者更高。我们提供的证据表明，黑白金丝猴能够应对地衣以外的一系列食物，因此可以被视为喂养多面手。我们参考之前对生活在栖息地的其他亚种群的研究结果进行讨论，这些栖息地的植物种类比小厂渡的边缘栖息地更加多样化，并且提供更多的植物性食物。是。 J.普里马托尔。 69:1141–1158, 2007。© 2007 Wiley-Liss, Inc.
The diet and feeding ecology of a wild subpopulation of black‐and‐white snub‐nosed monkeys (Rhinopithecus bieti) were studied at Xiaochangdu in Honglaxueshan Nature Reserve, Tibet. This region is climatologically harsher than any other inhabited by non‐human primates. Black‐and‐white snub‐nosed monkeys fed on 48 parts of 25 plant species, at least three species of lichens and seven species of invertebrates. The number of food items exploited varied markedly among seasons, with dietary diversity being greatest in spring and summer. In winter, black‐and‐white snub‐nosed monkeys had to subsist on fallback foods such as dried grass and bark. Ubiquitous lichens formed a major dietary constituent throughout the year, contributing about 75% of feeding records. Even though lichens act as a staple, our findings signify that the monkeys at Xiaochangdu prefer feeding on foliage, which is higher in protein content than the former. We provide evidence that black‐and‐white snub‐nosed monkeys are able to cope with an array of food items other than lichens and hence can be regarded as feeding generalists. We discuss the results with reference to previous studies on other subpopulations living in habitats that are floristically more diverse and offer more plant food items than the marginal habitat at Xiaochangdu.
