飞鸽(哥伦比亚鸽子)因其身体耐力和超强的定向感而被广泛研究。这些鸟类的极端身体耐力创造了一个独特的机会，可以研究长途飞行对肠道微生物区系的分类和代谢功能的可能影响。该项目是通过获得同一饲养员在相同条件下饲养的两组鸽子来实现的，只是其中一组鸽子接受了长途飞行训练，并在9周的时间里参加了总距离超过2600公里的多项比赛。相比之下，第二组没有飞行。利用16S扩增序列对粪便微生物区系进行分析，并根据序列数据推测其分类和代谢功能。根据系统发育距离和代谢功能，飞行鸽子和非飞行鸽子都有不同的细菌微生物区系。不同鸟类之间的微生物区系分类差异很大，而推断的代谢潜力相对稳定。年龄不是粪便微生物区系分布的重要决定因素。在飞行鸟类中，以生物合成为注解的代谢途径得到了丰富，占与飞行关系最密切的20条代谢途径的60%。
Flying pigeons (Columbia livia) are extensively studied for their physical endurance and superior sense of orientation. The extreme physical endurance of which these birds are capable creates a unique opportunity to investigate the possible impact of long-distance flying on the taxonomy and metabolic function of the gut microbiota. This project was enabled by access to two groups of pigeons raised by the same breeder in the same conditions, except that one group was trained in long-distance flying and participated in multiple races covering a total distance of over 2600 km over a 9-week period. In contrast, the second group did not fly. The fecal microbiota was analyzed using 16S amplicon sequencing, and the taxonomy and metabolic function were inferred from this sequence data. Based on phylogenetic distance and metabolic function, flying and non-flying pigeons were found to harbor distinct bacterial microbiota. The microbiota taxonomy varied extensively between the birds, whereas the inferred metabolic potential was relatively stable. Age was not a significant determinant of the fecal microbiota profile. In flying birds, the metabolic pathways annotated with biosynthesis were enriched, representing 60% of the 20 metabolic pathways that were most closely associated with flying.
