Comparative analysis on microbiome diversity in the GI tract and feces by α-diversity analyses. a. Maximum-likelihood phylogenetic tree comprising all of the taxa in the GI content and feces respectively. The rings of the circular dendrogram represent the family level and the corresponding phylum is depicted in the inner layer. b. Relative abundance of family level occupying in feces or the GI tract. c. Species richness and diversity measured by the indices of ACE richness, Shannon diversity and Fisher’s alpha
