Processed datasets and model outputs for tree-mortality effects on soil carbon and microbial strategies

This record provides the processed datasets and analysis outputs used to reproduce the results reported in the study “Topographic Decoupling of Tree-Mortality Disturbances Drives Contrasting Soil Carbon Fates via Divergent Microbial Strategies.” The deposited files include soil physicochemical properties, density-fractionated soil organic carbon data, extracellular enzyme activity data, bacterial 16S rRNA gene and fungal ITS amplicon feature tables, genome-informed microbial trait datasets, curated target-gene catalogues for carbon acquisition and terminal electron acceptor utilization, metagenome-derived gene count tables and functional annotations, and derived outputs from microbial community, phylogenetic, within-taxon trait-variation, machine-learning, and metagenomic gene-abundance analyses. These files correspond to the input data and saved analysis outputs required by the companion R code repository: https://github.com/zhangdx2025/tree-mortality-soil-carbon Together, the Zenodo dataset and the GitHub code repository allow regeneration of the numerical results, figures, supplementary figures, and supplementary tables reported in the associated manuscript. Raw amplicon and shotgun metagenomic sequencing reads are not included in this record and are deposited separately in the China National GeneBank Sequence Archive under project accessions CNP0008410 and CNP0008455.
