Background Understanding the role of gut microbiota in adapting to seasonal dietary and environmental fluctuations is essential for conservation endangered species. This study presents first comprehensive analysis variations critically hangul (Cervus hanglu hanglu), endemic Dachigam National Park, Jammu & Kashmir, India. Using high-throughput 16S rRNA gene sequencing, we analyzed 79 fecal samples collected four distinct seasons. Results Our results revealed Firmicutes Bacteroidota as dominant phyla throughout year, with significant shifts microbial diversity composition. Alpha metrics indicated a marked reduction richness evenness during autumn, potentially reflecting reduced forage quality. Beta analyses demonstrated clustering communities across seasons (PERMANOVA, p < 0.001), highlighting dynamic responses changes. Functional predictions inferred 429 functional pathways using PICRUSt2, identified variation metabolic pathways, increased lactose galactose degradation spring enhanced methanogenesis winter, adaptive strategies optimize host energy metabolism changing Network further restructuring interactions, identifying key taxa that drive transitions. The decline autumn underscores potential constraints faced by scarcity. Conclusions These findings provide critical insights into ecological physiological adaptability mediated microbiota, underscore importance integrating microbiome research strategies. Targeted habitat management interventions aligned natural dynamics could enhance health resilience populations facing anthropogenic pressures.
