3.5 Microhabitat differences between repeatedly and singly marked trees
We found a total of 157 scent marked trees, of which 139 were marked multiple times, accounting for 88.3% of all marked trees, and 18 were marked only once, accounting for 11.7% of all marked trees (Figure S1). One-way ANOVA was performed on the factors that might affect the frequency of marking, and we found no significant differences between roughness (P =0.65), DBH (P =0.82) and SDT (P =0.70) (Table S5).
