肠道微生物群被认为是动物生物学正常功能的重要资产。当野生动物被圈养时，改变的环境压力预计会重新连接肠道微生物群，但由于缺乏系统的多物种分析，这种转变是否在脊椎动物之间遵循类似的模式仍然悬而未决。我们对来自 24 种脊椎动物的 322 个圈养样本和 322 个野生样本的肠道微生物群概况进行了荟萃分析。我们的分析没有得出野生和圈养脊椎动物之间多样性和组成变化的总体模式，而是得出了异质的反应景观，其根据所考虑的多样性组成部分而有所不同。圈养种群显示出与人类相关的微生物的富集模式，最小的宿主系统发育信号表明野生种群和圈养种群之间的变化主要是由特定病例的圈养条件驱动的。最后，我们表明野生和圈养种群之间的微生物群差异可能会影响进化和生态推论，这些推论依赖于对跨物种肠道微生物群落进行分层聚类的比较分析。
The gut microbiota is recognised as an essential asset for the normal functioning of animal biology. When wild animals are moved into captivity, the modified environmental pressures are expected to rewire the gut microbiota, yet whether this transition follows similar patterns across vertebrates is still unresolved due to the absence of systematic multi-species analyses. We performed a meta-analysis of gut microbiota profiles of 322 captive and 322 wild specimens from 24 vertebrate species. Our analyses yielded no overall pattern of diversity and compositional variation between wild and captive vertebrates, but a heterogeneous landscape of responses, which differed depending on the components of diversity considered. Captive populations showed enrichment patterns of human-associated microorganisms, and the minimal host phylogenetic signal suggests that changes between wild and captive populations are mainly driven by case-specific captivity conditions. Finally, we show that microbiota differences between wild and captive populations can impact evolutionary and ecological inferences that rely on hierarchical clustering-based comparative analyses of gut microbial communities across species.
