Data for study of divergent microbial strategies under topographically decoupled disturbances linking contrasting soil carbon fates following tree mortality

This deposit provides the curated soil, microbial and genomic trait datasets used to reproduce the analyses in the study on topographically decoupled tree mortality disturbances, microbial strategies and soil organic carbon (SOC) dynamics in a subtropical forest. Files include soil physicochemical properties, bacterial and fungal amplicon feature tables (16S, ITS), metagenomic gene count tables and functional annotations for carbon-degrading and terminal-electron-acceptor utilization genes, genome-derived gene copy number variation matrices for bacterial and fungal taxa, and derived community and model outputs (e.g. microbial composition summaries and XGBoost cross-validation results). These tables correspond to the input data required by the R scripts in the companion code repository (https://github.com/zhangdx2025/tree-mortality-soil-carbon) and allow regeneration of the numerical results and figures in the associated manuscript. Raw sequencing reads are not included here; their access information is provided in the article.
