Abundance of MetaCyc pathways across different regions of the captive cynomolgus macaque intestinal tract. Pathways are categorised into higher-level organisational terms. Age groups are defined as 4–7 years (Young), 8–12 years (Adult) and 13–20 years (Aged). Within each facet, bars represent individual samples from different animals, arranged by ascending age from left to right. Pathway abundance is normalised and expressed as copies per million (CoPM) to account for variation in sequencing depth. D Duodenum
