  abstract = {{U}rbanization significantly impacts wild populations, favoring urban dweller species over those that are unable to adapt to rapid changes. {T}hese differential adaptative abilities could be mediated by the microbiome, which may modulate the host phenotype rapidly through a high degree of flexibility. {C}onversely, under anthropic perturbations, the microbiota of some species could be disrupted, resulting in dysbiosis and negative impacts on host fitness. {T}he links between the impact of urbanization on host communities and their gut microbiota ({GM}) have only been scarcely explored. {I}n this study, we tested the hypothesis that the bacterial composition of the {GM} could play a role in host adaptation to urban environments. {W}e described the {GM} of several species of small terrestrial mammals sampled in forested areas along a gradient of urbanization, using a 16{S} metabarcoding approach. {W}e tested whether urbanization led to changes in small mammal communities and in their {GM}, considering the presence and abundance of bacterial taxa and their putative functions. {T}his enabled to decipher the processes underlying these changes. {W}e found potential impacts of urbanization on small mammal communities and their {GM}. {T}he urban dweller species had a lower bacterial taxonomic diversity but a higher functional diversity and a different composition compared to urban adapter species. {T}heir {GM} assembly was mostly governed by stochastic effects, potentially indicating dysbiosis. {S}election processes and an overabundance of functions were detected that could be associated with adaptation to urban environments despite dysbiosis. {I}n urban adapter species, the {GM} functional diversity and composition remained relatively stable along the urbanization gradient. {T}his observation can be explained by functional redundancy, where certain taxa express the same function. {T}his could favor the adaptation of urban adapter species in various environments, including urban settings. {W}e can therefore assume that there are feedbacks between the gut microbiota and host species within communities, enabling rapid adaptation.},
