Diurnal rhythms of the gut microbiota are emerging as an important yet often overlooked facet microbial ecology. Feeding is thought to stimulate rhythmicity, but this has not been explicitly tested. Moreover, role environment entirely unexplored, with rhythmic changes pH rather than feeding per se possibly affecting fluctuations. In study, we experimentally manipulated schedule captive lesser long-nosed bats, Leptonycteris yerbabuenae, dissociate photic and cues, measured fecal every two hours. We detected strong diurnal in both alpha- beta diversity well within control group. However, a delay disrupted oscillations composition, did affect pH. The some genera, such Streptococcus, which aid metabolizing nutrients, shifted accordance delayed cue were correlated For other bacterial disturbed no connection was found. Our findings suggest that proliferation bacteria matches peak times, providing evidence likely evolved optimize their metabolic support host's circadian phenotype.
