摘要： Atmospheric nitrogen (N) deposition usually alters the ratio of resources to stress in terrestrial ecosystems and has important impacts on soil microbiomes. To elucidate the adaptability of soil microbiomes under N deposition scenarios, we conducted a 6-year N addition experiment in a temperate grassland in Inner Mongolia, applying different levels of ammonium nitrate (AN) and urea (AU) to form different resource-to-stress ratio. Our results reveal that the inborn high yield (Y)-resource acquisition (A)-stress tolerance (S) life history strategies of soil microbiomes collectively drive their adaptability to resources and stress under N deposition. Enriched taxa under AN treatment mainly belonged to Actinomycetota and Chloroflexota with Y and S strategies, while those under AU mainly belonged to Pseudomonadota with A and S strategies. Functional preference analysis indicated that bacterial phyla maintained consistent Y-A-S life history strategies across AN and AU treatments. Moreover, strong purifying selection restricted the pace of adaptive evolution, and horizontal gene transfer expanded the functional repertoire in a complementary rather than essential manner. Thus, the adaptation of microbiomes to shifting resources and stress under N deposition scenarios is mainly accomplished by niche conservatism (“move”) rather than niche evolution (“evolve”). Our results support the point that it may be easier for microbial species to move into a befitting niche than to evolve to acclimate a new environment.
