Seasonal Dynamics of Community and Function of Gut Microbiome in Taihangshan Macaque (Macaca mulatta tcheliensis): Inferred From Metagenomic Data

Integrative Zoology, EarlyView.
A total of 435 non‐redundant metagenome‐assembled genomes (MAGs) were obtained from fecal samples of Taihangshan macaque across all four seasons. The alpha diversity of the gut microbiome in spring and winter was significantly higher than in summer and autumn. Furthermore, marked differences were detected in functional pathways and carbohydrate enzymes
