No ASVs or genera were differentially abundant between captive and wild in all NHP species
We next employed ANCOM to test for ASVs that were differentially abundant between captive and wild individuals for each captive NHP population. These analyses indicated that hundreds of ASVs were differentially abundant between captive and wild individuals in at least one captive NHP population (Figure S3, Table S5). However, of the 262 ASVs detected in >2 of the 6 captive NHP populations, none were differentially abundant between captive and wild individuals in >2 of the 6 captive NHP populations (Table S5). Similarly, dozens of microbial genera were differentially abundant between captive and wild individuals in at least on captive NHP population (Figure 2, Table S6), but none were differentially abundant between captive and wild individuals in >3 of the 6 captive NHP populations (Table S6). This observation indicates that the individual ASVs and genera that were overrepresented or underrepresented in captive NHP population relative to wild conspecific populations varied across NHP species.
