The maps are distribution models for species-at-risk and endemic plant species of Beringia (Alaska and the Yukon). The models were labelled with the name of the species and suffixed by model scenarios. The files with _C are the current models and with _CNMR and _UKESM are the future models. The current models were generated with 1970-200 climatology baselines and the future models were generated using two General Circulation Models, namely CNMR-ESM2 and UKESM1-0-LL— Coupled Model Intercomparison Project, Phase 6. The models were generated using ensemble modelling approach.
The data value represents probability of occurrence, ranging from 0 to 1 but they have been multiplied by 1000 for computational reasons. The data were provided in WGS84 geographic coordinate system and at 4km (0.0416667 degree) resolution.
The methods were detailed in the published paper for the project. See https://onlinelibrary.wiley.com/doi/full/10.1111/ddi.13674 (Warming drives poleward range contractions of Beringian endemic plant species at high latitudes).
