The concept of eco-evolutionary (eco-evo) dynamics, stating that ecological and evolutionary processes occur at similar time scales and influence each other, has contributed to our understanding of responses of populations, communities, and ecosystems to environmental change. Phenotypes, central to these eco-evo processes, can be strongly impacted by the gut microbiome. The gut microbiome shapes eco-evo dynamics in the host community through its effects on the host phenotype. Complex eco-evo feedback loops between the gut microbiome and the host communities might thus be common. Bottom-up dynamics occur when eco-evo interactions shaping the gut microbiome affect host phenotypes with consequences at population, community, and ecosystem levels. Top-down dynamics occur when eco-evo dynamics shaping the host community structure the gut microbiome.
生态进化（eco-evo）动力学概念表明，生态和进化过程在相似的时间尺度上发生并相互影响，这有助于我们理解种群、群落和生态系统对环境变化的响应。表型是这些生态进化过程的核心，可能会受到肠道微生物群的强烈影响。肠道微生物群通过对宿主表型的影响塑造宿主群落中的生态进化动力学。因此，肠道微生物群与宿主群落之间复杂的生态进化反馈回路可能很常见。当塑造肠道微生物群的生态进化相互作用影响宿主表型，并在种群、群落和生态系统水平上产生后果时，就会发生自下而上的动力学。当塑造宿主群落的生态进化动力学构建肠道微生物群时，就会发生自上而下的动力学。
