Abstract：
The gut microbiome has the potential to buffer temporal variations in resource availability and consumption, which may play a key role in the ability of animals to adapt to a broad range of habitats. We investigated the temporal composition and function of the gut microbiomes of wild common marmosets (Callithrix jacchus) exploiting a hot, dry environment-Caatinga-in northeastern Brazil. We collected fecal samples during two time periods (July-August and February-March) for 2 years from marmosets belonging to eight social groups. We used 16S rRNA gene amplicon sequencing, metagenomic sequencing, and butyrate RT-qPCR to assess changes in the composition and potential function of their gut microbiomes. Additionally, we identified the plant, invertebrate, and vertebrate components of the marmosets\' diet via DNA metabarcoding. Invertebrate, but not plant or vertebrate, consumption varied across the year. However, gut microbiome composition and potential function did not markedly vary across study periods or as a function of diet composition. Instead, the gut microbiome differed markedly in both composition and potential function across marmosets residing in different social groups. We highlight the likely role of factors, such as behavior, residence, and environmental heterogeneity, in modulating the structure of the gut microbiome.
OBJECTIVE: In a highly socially cohesive and cooperative primate, group membership more strongly predicts gut microbiome composition and function than diet.

摘要：
肠道微生物组有可能缓冲资源可用性和消耗的时间变化，这可能在动物适应广泛栖息地的能力中起关键作用。我们研究了野生普通猴（Callithrixjacchus）的肠道微生物组的时间组成和功能，干燥的环境-卡廷加-在巴西东北部。我们在两个时间段（7月至8月和2月至3月）从属于八个社会群体的and猴中收集了2年的粪便样本。我们使用16SrRNA基因扩增子测序，宏基因组测序，和丁酸盐RT-qPCR来评估其肠道微生物群的组成和潜在功能的变化。此外,我们确认了植物的身份,无脊椎动物,和脊椎动物的组成部分，通过DNA的代谢编码。无脊椎动物,但不是植物或脊椎动物，全年消费不同。然而,肠道微生物组组成和潜在功能在研究期间或作为饮食组成的函数没有明显变化。相反，居住在不同社会群体中的the猴的肠道微生物组在组成和潜在功能上都存在显着差异。我们强调了因素可能的作用，比如行为，residence,和环境异质性，调节肠道微生物组的结构。
目的：在一个高度社会凝聚力和合作的灵长类动物中，与饮食相比，组员更强烈地预测肠道微生物组组成和功能。
