The relationships between species diversity and environmental factors based on the Mantel test. (a) The heatmap displays correlations between various environmental factors, with each row and column representing a specific factor. The color intensity indicated the strength and direction of the correlation coefficient, where darker shades signified stronger positive or negative correlations, and lighter shades denoted weaker or nonsignificant correlations. Connecting lines between the sites and environmental factors highlighted significant Mantel test correlations. Asterixis indicate significant differences: **P value < 0.01. (b) The Mantel correlogram for beta diversity and alpha diversity, Se, H2O, and pH. The value of the Mantel correlation coefficient is shown on the y-axis for each condition, while the x-axis displays the different levels of the factors. The red dots indicating statistical significance at P < 0.05.
