Correlation between serum DHEA concentration and the gut microbiome and aggressive behavior in male hamsters following 9 weeks of photoperiodic treatment. (A,B) Serum DHEA concentration was significantly correlated with the number of attacks (A) and attack duration (B) in males. (C) The correlation between serum DHEA concentration and the relative abundance of Patescibacteria in males tended towards significance. For each treatment group (LD: N=4, SD-R: N=6, SD-NR: N=4), correlation coefficients (ρ) and P-values are shown (Spearman's rank correlations).
