所有动物都携带专门的微生物群，它们的肠道微生物群通过排泄废物不断释放到环境中。在这里，我们提出了一个新的概念框架，解决了从动物释放的肠道微生物组在宿主外发挥作用并改变微生物介导的生物化学过程的能力。我们在河马和它们栖息的水池中展示了这种动态。我们使用自然场梯度和实验方法来研究粪便和池水微生物群落和水生生物地球化学在一系列河马输入。使用16S RNA方法进行测序，揭示了河马肠道微生物组与接受高河马粪便输入的河马池中的活性微生物群落之间的群落聚结。河马肠道和它们排泄的沃茨之间共享的微生物组构成了一个后肠道系统，可以影响受体生态系统的生物地球化学，并提供一个可能影响其他宿主的肠道微生物组库。我们建议，后肠动力学也可能发生在其他动物物种聚集在高密度，特别是在水生环境中。
All animals carry specialized microbiomes, and their gut microbiota are continuously released into the environment through excretion of waste. Here we propose the meta-gut as a novel conceptual framework that addresses the ability of the gut microbiome released from an animal to function outside the host and alter biogeochemical processes mediated by microbes. We demonstrate this dynamic in the hippopotamus (hippo) and the pools they inhabit. We used natural field gradients and experimental approaches to examine fecal and pool water microbial communities and aquatic biogeochemistry across a range of hippo inputs. Sequencing using 16S RNA methods revealed community coalescence between hippo gut microbiomes and the active microbial communities in hippo pools that received high inputs of hippo feces. The shared microbiome between the hippo gut and the waters into which they excrete constitutes a meta-gut system that could influence the biogeochemistry of recipient ecosystems and provide a reservoir of gut microbiomes that could influence other hosts. We propose that meta-gut dynamics may also occur where other animal species congregate in high densities, particularly in aquatic environments.
