Spearman correlation coefficient for the relationship between fear-related behavior and different bacterial genera in the gut of laying hens. Heat maps show notable statistical correlation values (r), where red squares indicate significant positive correlation (0 < r ≤ 1), white squares no correlation (r = 0), and blue squares significant negative correlation (−1 ≤ r < 0). Deeper color hue indicates stronger correlation (*P < 0.05, ** P < 0.01).
