Spatial genetic correlation in high-mountain species in La Palma and Tenerife
We assessed genetic structure, landscape resistance, and projected habitat change for eight alpine endemic plant species across the two main high-mountain systems of the Canary Islands: Teide National Park (Tenerife) and Caldera de Taburiente National Park (La Palma). Environmental differentiation between islands was driven primarily by precipitation, whereas temperature structured variation within islands. Fine-scale spatial genetic structure did not differ between short- and long-distance seed dispersers, suggesting compensatory pollen-mediated gene flow and species-specific life-history effects. New markers were developed for Cheirolophus teydis. Therefore, the primer sequences are uploaded.
