Spearman’s rank correlation between occupant intensity (<i>Nd</i>) and combined relative abundance of selected group of genera and Shannon diversity index values.

<p>The left frames showcase the correlations of bacteria and the right frames are for fungi. The symbol <i>ρ</i> indicates the Spearman’s rank correlation coefficient and * denotes statistical significance for the correlation at <i>p</i> < 0.05 with <i>n</i> = 5. ^a Correlation between occupant intensity and the group of human-related bacterial genera based on Qian et al.
