Abstract

Wild animals face numerous challenges in less ideal habitats, including the lack of food as well as changes in diet. Understanding how the gut microbiomes of wild animals adapt to changes in food resources within suboptimal habitats is critical for their survival. Therefore, we conducted a longitudinal sampling of three gibbon species living in high-quality (Nomascus hainanus) and suboptimal (Nomascus concolor and Hoolock tianxing) habitats to address the dynamics of gut microbiome assembly over one year. The three gibbon species exhibited significantly different gut microbial diversity and composition. N. hainanus showed the lowest alpha diversity and highest nestedness, suggesting a more specialized and potentially stable microbial community in terms of composition, while H. tianxing displayed high species turnover and low nestedness, reflecting a more dynamic microbial ecosystem, which may indicate greater sensitivity to environmental changes or a flexible response to habitat variability. The gut microbial community of N. concolor was influenced by homogeneous selection in the deterministic process, primarily driven by Prevotellaceae. In contrast, the gut microbial communities of H. tianxing and N. hainanus were influenced by dispersal limitation in the stochastic process, driven by Acholeplasmataceae and Fibrobacterota, respectively. Further, the microbial response patterns to leaf feeding in N. hainanus differed from those of the other two gibbon species. In conclusion, this first cross-species comparative study provides initial insights into the different ecological adaptive strategies of gut microbiomes from a point of community assembly, which could contribute to the long-term conservation of wild primates. In this study, we conducted longitudinal sampling of three gibbon species living in high-quality (Nomascus hainanus) and suboptimal (Nomascus concolor and Hoolock tianxing) habitats to address the dynamics of gut microbiome (composition, alpha diversity, beta diversity and assembly process) over one year.

肠道菌群的比较研究揭示了生活在次优栖息地的长臂猿的适应策略。
野生动物在不太理想的栖息地面临着许多挑战,包括食物的缺乏和饮食的变化。了解野生动物的肠道微生物群如何适应食物资源的变化,对它们的生存至关重要。因此,我们对生活在优质(海南野长臂猿)和次优(concolor野长臂猿和天星野长臂猿)栖息地的三种长臂猿进行了纵向采样,以研究一年内肠道微生物群的动态变化。三种长臂猿的肠道微生物多样性和组成差异显著。海南海桐的α多样性最低,巢性最高,表明其微生物群落在组成上更为特化和稳定;天星海桐的物种更替率高,巢性低,表明其微生物生态系统更具动态性,可能对环境变化更敏感或对栖息地变异性的反应更灵活。大肠杆菌的肠道微生物群落在确定性过程中受到同质选择的影响,主要由普氏菌科驱动。相比之下,天星H. tianxingh .和海南N. hainanus的肠道微生物群落分别受到木浆菌科(Acholeplasmataceae)和纤维菌群(Fibrobacterota)驱动的随机扩散限制的影响。此外,海南长臂猿对叶片取食的微生物响应模式与其他两种长臂猿不同。总之,这项首次跨物种比较研究从群落组装的角度初步了解了肠道微生物组的不同生态适应策略,这可能有助于野生灵长类动物的长期保护。本研究对生活在优质栖息地(海南野长臂猿)和次优栖息地(concolor野长臂猿和天星野长臂猿)的3种长臂猿进行了1年的纵向采样,以研究肠道微生物组的组成、α多样性、β多样性和组装过程。

期刊介绍: npj Biofilms and Microbiomes is a comprehensive platform that promotes research on biofilms and microbiomes across various scientific disciplines. The journal facilitates cross-disciplinary discussions to enhance our understanding of the biology, ecology, and communal functions of biofilms, populations, and communities. It also focuses on applications in the medical, environmental, and engineering domains. The scope of the journal encompasses all aspects of the field, ranging from cell-cell communication and single cell interactions to the microbiomes of humans, animals, plants, and natural and built environments. The journal also welcomes research on the virome, phageome, mycome, and fungome. It publishes both applied science and theoretical work. As an open access and interdisciplinary journal, its primary goal is to publish significant scientific advancements in microbial biofilms and microbiomes. The journal enables discussions that span multiple disciplines and contributes to our understanding of the social behavior of microbial biofilm populations and communities, and their impact on life, human health, and the environment.
