Age is known to affect the gut microbiota in various animals; however, this relationship is poorly understood in seabirds. We investigated the temporal succession of gut microbiota in captive chinstrap penguins of different ages using high‐throughput sequencing. The gut microbiota exhibited a significant age succession pattern, reaching maturity in adults and then declining with increasing age. Only 15 amplicon sequence variants were shared among the gut microbiota in chinstrap penguins at all studied ages, and these contributed to most of the age‐related variations in total gut microbiota. Co‐occurrence networks found that these key bacteria belonged to the genera Acinetobacter, Clostridium sensu stricto, and Fusobacterium, and more species interactions were found within the same taxonomy. Functional prediction indicated that most of the metabolic functions were more abundant in the gut microbiota in adult chinstrap penguins, except for carbohydrate metabolism, which was significantly more abundant in older individuals.

帽带企鹅（Pygoscelis antarctica）肠道微生物群与年龄相关的变化揭示了食物代谢的差异
众所周知，年龄会影响各种动物的肠道微生物群。然而，人们对海鸟的这种关系知之甚少。我们使用高通量测序研究了不同年龄的圈养帽带企鹅肠道微生物群的时间连续性。肠道微生物群表现出显着的年龄演替模式，在成年人中达到成熟，然后随着年龄的增长而下降。在所有研究年龄的帽带企鹅肠道微生物群中，只有 15 个扩增子序列变异是共享的，而这些变异导致了总肠道微生物群中大部分与年龄相关的变异。共现网络发现这些关键细菌属于不动杆菌属、狭义梭菌属和梭杆菌属，并且在同一分类中发现了更多物种相互作用。功能预测表明，成年帽带企鹅肠道微生物群中的大多数代谢功能都更加丰富，但碳水化合物代谢除外，后者在老年个体中明显更加丰富。
