Divergent Assembly of Bacteria and Fungi During Saline-Alkali Wetland Degradation.

ABSTRACT: To clarify microbial assembly during saline-alkali wetland degradation, we analyzed bacterial (16S rRNA) and fungal (ITS) communities across four habitats: pristine wetland (PW), transitional meadow wetland (TMW), halophytic herbaceous community (HHC), and converted farmland (CF). Soil water content collapsed from PW (42.22%) to ≤18.40% elsewhere, and soils were alkaline with pH highest in HHC (10.08). Nutrient pools and enzyme activities were highest in PW (SOC 35.03 g kg^-1; URE 142.58 mg g^-1; SUC 527.83 mg g^-1) but declined sharply under natural degradation, reaching minima in HHC (SOC 8.02 g kg^-1). ACP and CAT were also lowest in HHC. Bacterial communities were dominated by Actinomycetota and Pseudomonadota, with Acidobacteriota and Bacillota
