The Effects of Drainage on the Soil Fungal Community in Freshwater Wetlands

Wetland drainage has been intensively implemented globally, and it exerted significant effects on wetland ecosystems. The of the soil fungal community remain to be clarified. Soil samples were collected at depths 0–5 5–10 cm in freshwater Phragmites australis wetlands investigate changes before after (termed FW DFW, respectively) using high-throughput sequencing fungal-specific internal transcribed spacer 1 (ITS1) gene region. No differences α diversity found 0–10 soils between DFW ( p > 0.05), except for abundance-based coverage estimator (ACE) Chao1 indices soils. Significantly higher values ACE than indicated that may reduce richness Ascomycota, Sordariomycetes, Cephalothecaceae dominant phylum, class, family, respectively, both representing as high 76.17, 58.22, 45.21% soils, respectively. Saprotrophic fungi predominated DFW. Drainage altered structure some edaphic factors. Mantel tests Spearman correlation analyses implied factors [i.e., organic matter (SOM), electronic conductivity (EC), pH, clay] also affected structure. Overall, wetlands.
