Analysis code, OTU tables and sample metadata for "Salinity structures cross-domain microbial communities along a hypersaline gradient in a solar saltern"

Reproducible analysis package for the above study. Contains the input OTU abundance tables (16S rRNA gene, 18S rRNA gene and ITS2 amplicons), sample metadata, and the Python analysis code (scikit-bio, SciPy) that reproduces the alpha- and beta-diversity statistics and Figures 1-5 reported in the paper: alpha-diversity indices and their regressions against salinity, Bray-Curtis beta diversity computed on relative abundances, PCoA ordinations, PERMANOVA, PERMDISP and Mantel tests (999 permutations), plus the sensitivity analysis of beta diversity to rarefaction depth. Raw amplicon sequencing reads are deposited separately in the NCBI Sequence ReadArchive under BioProject PRJNA1117021 (runs SRR38744715-SRR38744774) and were publicly released on 26 August 2026.
