Overview

Randomized trial investigates gut microbiota diversity from specialized diets in mammals, suggesting dietary variability benefits conservation efforts.

Key Points

  • This research aims to understand how specialized plant-based diets affect gut microbiota in mammals.
  • Investigated gut microbiomes of dietary specialists including bamboo rats, pandas, and red pandas.
  • Integrated 16S rRNA and metagenomic data with enzyme assays to assess lignocellulose degradation capability.
  • Compared microbiota diversity and metabolic functions across different feeding guilds.
  • Gut microbiota diversity significantly decreased among dietary specialists, particularly in polysaccharide metabolism (p<0.01).
  • Lignocellulose-degrading enzyme activity was markedly lower in bamboo rats compared to other specialists (p<0.05).
  • Enrichment of detoxification pathways was observed, suggesting host-microbe compensatory strategies during dietary adaptation.
