Recorded and predicted occurrence of Eumycetozoa in Poland from Central and Eastern European data

For each taxon, the table provides taxonomic placement, countries of occurrence, aggregated habitat and substrate descriptors, collated bibliography and, where available, species distribution model (SDM) metrics, Polish suitability indicators and probability class, together with top Polish regions. Supplementary Material 1.3 – model performance metrics Evaluation results for MaxEnt‑type SDMs fitted to candidate species with sufficient data.

For each modelled taxon, the table reports sample size, number of cross‑validation folds and AUC statistics, together with attempted Boyce indices. It allows users to assess the strength and uncertainty of individual models. Supplementary Material 1.4 – top Polish regions per species Region‑level summary indicating, for each modelled candidate species, up to three Polish voivodeships with the largest proportion of grid cells classified as climatically suitable.

Voivodeships are listed by their Polish names and can be used to prioritise areas for targeted surveys and validation. Supplementary Material 1.5 – map collection (Supplementary Figures 1–101) Set of 101 raster maps showing predicted potential distributions in Poland for modelled candidate species. Each figure displays continuous climatic suitability and the subset of grid cells exceeding a 10th‑percentile training‑presence threshold.

Supplementary Material 1.6 – bibliographic list Alphabetically ordered list of all bibliographic sources used in the Polish checklist (Supplementary Material 1.1). It contains the full citations in Harvard style corresponding to the condensed reference strings in the checklist table.
