Spearman’s correlation coefficient between the occurrence of microsporidians and environmental factors: a temperature, b humidity, c wind and d rainfall. The thickness of line indicates the correlation coefficient. Solid lines indicate statistical significance at p < 0.05; dashed lines indicate no statistical significance. For correlation values and their statistical significance, see Additional file 1: Table S6.
