EMF index with different selective logging intensities. Different lower case letter represents significant difference at P < 0.05 level. EMF index (mean values ± standard error) for each treatment on the top of each boxplot. CG: control group; SL1: selective logging one time; SL2: selective logging two times; SL3: selective logging three times; SL4: selective logging four times; SL5: selective logging five times
