Variation in the availability and distribution of food resources is a strong selective pressure on wild primates. We explored variation in Tibetan macaque gut microbiota composition during winter and spring seasons. Our results showed that gut microbial composition and diversity varied by season. In winter, the genus Succinivibrio, which promotes the digestion of cellulose and hemicellulose, was significantly increased. In spring, the abundance of the genus Prevotella, which is associated with digestion of carbohydrates and simple sugars, was significantly increased. PICRUSt analysis revealed that the predicted metagenomes related to the glycan biosynthesis and metabolic pathway was significantly increased in winter samples, which would aid in the digestion of glycan extracted from cellulose and hemicellulose. The predicted metagenomes related to carbohydrate and energy metabolic pathways were significantly increased in spring samples, which could facilitate a monkey's recovery from acute energy loss experienced during winter. We propose that shifts in the composition and function of the gut microbiota provide a buffer against seasonal fluctuations in energy and nutrient intake, thus enabling these primates to adapt to variations in food supply and quality.
食物资源的可获得性和分布变化是野生灵长类动物面临的强大选择压力。我们探究了冬季和春季期间藏猕猴肠道微生物群组成的变化。我们的结果表明，肠道微生物组成和多样性随季节而变化。在冬季，促进纤维素和半纤维素消化的琥珀酸弧菌属显著增加。在春季，与碳水化合物和单糖消化相关的普雷沃氏菌属丰度显著增加。PICRUSt分析显示，与聚糖生物合成和代谢途径相关的预测宏基因组在冬季样本中显著增加，这将有助于消化从纤维素和半纤维素中提取的聚糖。与碳水化合物和能量代谢途径相关的预测宏基因组在春季样本中显著增加，这可以促进猕猴从冬季经历的急性能量损失中恢复。我们认为，肠道微生物群组成和功能的变化为能量和营养摄入的季节性波动提供了缓冲，从而使这些灵长类动物能够适应食物供应和质量的变化。
