The outcomes of host-symbiont interactions may differ according to environmental context, and symbioses may enable host adaptation to diverse environments. We find that the effects of two different experimental diets, algae and yeast, on the water flea Daphnia magna depend on whether the animals possess microbiota, suggesting that the presence of microbiota determines which diet is superior. Our study hints at both diet-dependent and diet-independent effects of microbiota on Daphnia fitness.
宿主与共生体相互作用的结果可能因环境背景而异,共生关系可能使宿主适应各种环境。我们发现,两种不同的实验性食物(藻类和酵母)对水蚤大型溞的影响取决于动物是否拥有微生物群,这表明微生物群的存在决定了哪种食物更具优势。我们的研究暗示了微生物群对大型溞健康的饮食依赖性和非饮食依赖性影响。
