Seasonal resource fluctuations are associated with gut mycobiome reassembly in wild macaques on the western Sichuan Plateau: annual-scale evidence for exogenous inputs
High-altitude environments on the western Sichuan Plateau show strong seasonal fluctuations in resource availability, which may drive annual turnover of host gut fungal communities by altering dietary inputs and environmental exposure. In this study, we conducted fecal sampling over 12 consecutive months from a single wild macaque population, collecting a total of 100 samples. Using ITS amplicon sequencing, we characterized temporal variation in gut mycobiome composition and assessed potential ecological indicator value through functional guild prediction with FUNGuild.
