Mammals show distinct functional gut microbiome dynamics to identical series of environmental stressors.

ABSTRACT: The ability of the gut microbiome has been posited as an additional axis of animals' phenotypic plasticity. However, whether and how such plasticity varies across hosts with different biological features remains unclear. We performed a captivity experiment to compare how the taxonomic, phylogenetic, and functional microbial dynamics varied across a series of temperature and dietary disturbances in two mammals: the insectivorous-specialist Crocidura russula and the omnivorous-generalist Apodemus sylvaticus. Combining genome-resolved metagenomics, metabolic pathway distillation and joint species distribution modeling, we observed that, although microbiome alpha diversity of both species remained stable, C. russula exhibited substantially higher variability and directiona
