Ensemble species distribution models for 69 marine non-indigenous species in European waters: current and future scenarios.

Résumé fourni par la source

Data and model outputs for ensemble species distribution modeling of 69 marine non-indigenous species across European watersThis repository contains the input data, model outputs, and performance metrics associated with [Author et al. (in review/in press)] available at [DOI to be added upon publication]. The dataset supports ensemble species distribution modeling analyses of marine non-indigenous species under current and future climate scenarios (SSP1-2.6, SSP2-4.5, SSP5-8.5 for 2100).Repository structure:Code and scriptsARMS-marine-alien-SDM-main.zip: Complete R workflow scripts archived from GitHub for full reproducibility of all analyses (https://github.com/JustinePa/ARMS-marine-alien-SDM/tree/main)Raw occurrence downloadsraw_occurrences_downloads/gbif/: Zipped raw GBIF downloads (one per species) containing dataset identifiers for data provenanceraw_occurrences_downloads/obis/: Raw OBIS downloads (one per species) containing dataset identifiers for data provenanceInput datainput_data/final_occurrences_thinned_curated/: Spatially thinned and quality-controlled occurrence records used for modeling (one file per species)input_data/environmental_data/: Environmental predictor layers for current conditions (myExpl_shelf.tif) and future projections (ssp126_shelf_2100.tif, ssp245_shelf_2100.tif, ssp585_shelf_2100.tif)Model outputsraw_outputs/: Zipped folders containing species-level ensemble model projections (one .tif per species) for:raw_EMwmean_*: Ensemble mean weighted by evaluation metrics (current, SSP1-2.6, SSP2-4.5, SSP5-8.5)raw_EMcv_*: Ensemble coefficient of variation indicating prediction uncertainty (current, SSP1-2.6, SSP2-4.5, SSP5-8.5)raw_EMca_*: Ensemble committee averaging (current, SSP1-2.6, SSP2-4.5, SSP5-8.5)Multi-species richness patternsstacked_EMwmean_allScenarios/: Combined suitability projections across all 69 modeled species, normalized to 0-1 scale:stack_mean_norm01_current.tif: Current conditionsstack_mean_norm01_ssp126.tif: SSP1-2.6 scenario (2100)stack_mean_norm01_ssp245.tif: SSP2-4.5 scenario (2100)stack_mean_norm01_ssp585.tif: SSP5-8.5 scenario (2100)Model performance assessmentmodel_performance/individual_models_performance_assessment/: Evaluation metrics for individual modeling algorithms (one file per species)model_performance/ensemble_models_performance_assessment/: Evaluation metrics for ensemble model projections (one file per species)This dataset enables full reproducibility of the modeling workflow and provides species-level projections for researchers and marine resource managers interested in individual species distributions beyond the multi-species patterns presented in the associated publication.
