Summary

Story summary

Seasonal changes shift Eurasian otters' diet and gut microbiota in Northeast China, with snowfall prompting fish-to-forest frog switches.
In snow-free seasons, Firmicutes dominate the otter gut, while Proteobacteria prevail in snowy conditions.
Romboutsia and Pseudomonas are key genera linked to dietary shifts.
Temperature reduces gut microbiota diversity. Captivity lowers diversity versus wild in bears and pandas, signaling a need for species-specific conservation.
