Clomazone impact on fungal network complexity and stability
Summary
Researchers investigated how the herbicide clomazone affected soil fungal network complexity and stability, finding that while node count decreased by 12-42, average degree and network density increased under clomazone treatment, and overall network robustness improved while vulnerability decreased, indicating increased but restructured fungal network stability.
Under the influence of clomazone, the fungal network nodes were decreased by 12-42; however, the average degree was increased by 0.169-1.468 and fungal network density was increased by 0.003-0.054. The keystone nodes were significantly changed after clomazone treatment. Network composition was also impacted. Specifically, compared with control and clomazone treatments in both soils, the shared edges were fewer than 54 in all comparisons, and network dissimilarity was 0.97-0.98. These results suggested that fungal network composition was significantly impacted. The network robustness was increased by 0.0018-0.0209, and vulnerability was decreased by 0.00018-0.00059 in both soils, which indicated that fungal network stability was increased by clomazone. In addition, the functions of network communities were also changed in both soils. These results indicated that clomazone could significantly impact soil fungal networks.
