农业的扩张正在全球范围内缩小原始森林面积，危及其野生居民的持续存在。乌宗瓦红疣猴（Procolobus gordonorum）是非洲最受威胁的灵长类动物之一。它们是原始的树栖生物，对狩猎和栖息地破坏高度敏感，为了解人为干扰是否影响肠道微生物群多样性提供了一个重要模型。我们采样了七个社会群体居住在两个森林（干扰与不受干扰）在坦桑尼亚的Udzungwa山脉。虽然Ruminococcaceae和Lachnospiraceae在所有个体中占主导地位，反映了它们在从食叶性饮食中提取能量方面的作用，但属组成的分析显示出栖息地之间的显着多样性，未受干扰的森林中肠道微生物群α多样性显着较高。功能分析表明，这种变化可能与粮食植物多样性在自然与人类改造的栖息地，需要代谢途径来消化异生物质。因此，肠道微生物群变化的影响不应被忽视，以保护濒危种群。
The expansion of agriculture is shrinking pristine forest areas worldwide, jeopardizing the persistence of their wild inhabitants. The Udzungwa red colobus monkey (Procolobus gordonorum) is among the most threatened primate species in Africa. Primarily arboreal and highly sensitive to hunting and habitat destruction, they provide a critical model to understanding whether anthropogenic disturbance impacts gut microbiota diversity. We sampled seven social groups inhabiting two forests (disturbed vs. undisturbed) in the Udzungwa Mountains of Tanzania. While Ruminococcaceae and Lachnospiraceae dominated in all individuals, reflecting their role in extracting energy from folivorous diets, analysis of genus composition showed a marked diversification across habitats, with gut microbiota α-diversity significantly higher in the undisturbed forest. Functional analysis suggests that such variation may be associated with food plant diversity in natural versus human-modified habitats, requiring metabolic pathways to digest xenobiotics. Thus, the effects of changes in gut microbiota should not be ignored to conserve endangered populations.
