Arthropod ASVs richness at multi-hierarchical levels
The rarefaction curves indicate that the sampling effort was enough to achieve from 60 to 91% completeness at the haplotype and 3% CL in four of the eight taxa groups (Diptera, Collembola, Arachnida and Hymenoptera Figure S3). The groups that showed larger richness within the communities (alpha diversity by sample) were Diptera (mean = 87 SD ± 23.1 haplotypes and mean = 21 ± 5.15 lineages at 3%), Collembola (mean = 38 ± 9.44 haplotypes and mean = 16 ± 2.91 lineages at 3%), and Arachnida (mean = 12 ± 6.28 haplotypes and mean = 9 ± 3.64 lineages at 3%). Some groups showed significant differences between sampling sites but richness patterns across sites were not consistent for the different arthropod groups (Figure 3). The sampling site that presented the highest mean (± SD) richness of haplotypes was TLC with 103 (± 19.2) and 38 (± 10.7) haplotypes for Diptera and Collembola, respectively; followed by SJH with 94 (± 9.31) and 42 (± 13.7) haplotypes for Diptera and Collembola. The sampling site showing the highest richness at higher clustering levels was ASB with Diptera (mean = 25 ± 2.65 and mean = 24 ± 2.45, for CLs 3 and 5%, respectively) and Collembola (mean = 17 ± 2.13 and mean = 15 ± 2.22 for CLs 3 and 5%, respectively); followed by SJH with Diptera (mean = 22 ± 4.04 and mean = 20 ± 4.24, for CLs 3 and 5% respectively), and Collembola (mean = 16 ± 2.28 and mean = 15 ± 2.12, for CLs 3 and 5% respectively; Figure 3).
