Intersite differences in gut microbiome are associated with habitat quality in a limestone forest-dwelling langur

Our study concludes that intersite differences in gut microbiome are associated with habitat quality in the François' langurs, underscoring its role in habitat adaptation and necessity for physiological indicators to elucidate the mechanisms by which wildlife responds to human disturbance and ecological variability. In addition, we recommend prioritizing the restoration of native vegetation diversity in the langurs' habitats, which leverages their gut microbiota's adaptive potential to provide a suitable fundamental environment for the langurs' long-term survival.
