| Resumo: | A phytogeographic approach of Abies alba Mill. populations in the Spanish side of the Pyrenees Range is provided. The methodology is based on >Species distribution models> (SDMs) and palaeopalynological Quaternary records from Pyrenees. Articulating the results derived from the SDMs (topo-climatic perspective), and a review of the Quaternary fossil record (climate and anthropic approach), we try to build a historical understanding of the dynamics of these forests. Both tools reveal that Abies alba only occupy a small proportion of their potential distribution range (30%) and offer geographic evidence demonstrating that these populations had a wider altitudinal distribution in the past. We suggest the use of SDMs to reinforce assumptions about the Quaternary distribution of the Iberian Abies alba forest, and to locate refugia for the long-term persistence. |
