Effects of naphthalene on the number of dominant fauna in the subalpine forest of western Sichuan. (A) Dominant group of soil arthropods in 2016 (at the order level); (B) Dominant group of soil arthropods in 2017 (at the order level); (C) dominant group of Collembola in 2016 (at the family level); (D) dominant group of Collembola in 2017 (at the family level); (E) dominant group of Acarina in 2016 (at the family level); (F) dominant group of Collembola in 2017 (at the family level); Values represent the means ± SE (n = 3, three sites with three replicates at each site). Asterisks indicate significant (*P < 0.05, **P < 0.01) differences in soil arthropod density and number of groups between different sampling times.
