The bolded genera were shared between the ANIM-B and the DMI-B models.

Uncl unclassified.

For all the models, the predictor variables were centered and scaled to have a mean of 0 and variance of 1.

**Log-transformed relative sequence abundance.

¹Developed using glmmLasso and all the available data after log transformation of the microbial data.

²Developed using conventional model and only animal-related data.
