Aim: In island-like habitats, geographic isolation facilitates population and species divergence by constraining gene flow, while environmental isolation can enhance divergence. We tested the relative contribution of geographic and environmental isolation in genetic and phenotypic divergence within and between two species of the figwort Ameroglossum (Scrophulariaceae) inhabiting spatially isolated habitats, known as inselbergs. Location: Borborema Plateau, north-eastern Brazil. Methods: Multivariate models of redundancy (RDAs) and partial redundancy analyses (pRDAs) were used to partition the geographic...
