Past projections of submediterranean oaks unveil future range shifts of vulnerable taxa under climate change

This Digital Annex accompanies the article “Past projections of submediterranean oaks unveil future range shifts of vulnerable taxa under climate change”, accepted for publication in Scientific Reports. The archive contains species occurrence records and supplementary projection maps used to support the ensemble Species Distribution Models presented in the manuscript. These materials include occurrence data for the eight focal circummediterranean marcescent oak taxa — Quercus boissieri, Q. canariensis, Q. faginea, Q. infectoria, Q. kotschyana, Q. lusitanica, Q. pyrenaica and Q. vulcanica — together with mapped outputs of past, current and future climatic suitability projections. The projection maps document past-to-present and present-to-future changes in climatic suitability, including areas of loss, gain, stable suitability and stable unsuitability across Late-Quaternary periods and future SSP scenarios. These files provide the spatial basis for the range-shift analyses, conservation interpretation and supplementary mapping referenced in the main text and Supplementary Information. Species distribution maps were generated by the authors in R v.4.4.1 (https://www.r-project.org/) from occurrence datasets and ensemble SDM outputs, and subsequently assembled and edited in ArcMap v.10.5 (https://www.esri.com/en-us/arcgis).
