Shift of ingestive behavior is an important strategy for animals to adapt to change of the environment. We knew that shifts in animal dietary habits lead to changes in the structure of the gut microbiota, but we are not sure about if changes in the composition and function of the gut microbiota respond to changes in the nutrient intake or food items. To investigate how animal feeding strategies affect nutrient intakes and thus alter the composition and digestion function of gut microbiota, we selected a group of wild primate group for the study. We quantified their diet and macronutrients intake in four seasons of a year, and instant fecal samples were analyzed by high-throughput sequencing of 16S rRNA and metagenomics. These results demonstrated that the main reason that causes seasonal shifts of gut microbiota is the macronutrient variation induced by seasonal dietary differences. Gut microbes can help to compensate for insufficient macronutrients intake of the host through microbial metabolic functions. This study contributes to a deeper understanding of the causes of seasonal variation in host-microbial variation in wild primates.
摄食行为的转变是动物适应环境变化的重要策略。我们知道动物饮食习惯的改变会导致肠道微生物群结构的变化，但我们不确定肠道微生物群的组成和功能变化是否会对营养摄入或食物种类的变化做出反应。为了研究动物的进食策略如何影响营养摄入，进而改变肠道微生物群的组成和消化功能，我们选择了一组野生灵长类动物进行研究。我们量化了它们在一年四个季节中的饮食和常量营养素摄入量，并通过对16S rRNA的高通量测序和宏基因组学分析即时粪便样本。这些结果表明，导致肠道微生物群季节性变化的主要原因是季节性饮食差异引起的常量营养素变化。肠道微生物可以通过微生物代谢功能帮助弥补宿主常量营养素摄入不足。这项研究有助于更深入地理解野生灵长类动物宿主-微生物变化季节性差异的原因。
