Laurel forest in the Anaga Mountains on Tenerife (photos A. Betzin).
Fig 2.
Stem age estimates of the studied laurel forest species (Ma: million years ago).
Bars show the 95% HPD, mean stem ages are marked by a vertical black line. Asterisks (*) indicate taxa whose mrca habitat is not optimised as laurel forest.

Stem age estimates of MLF taxa using BEAST as means and 95% highest posterior densities (HPD) in Ma.

Results of BayesTraits analyses concerning laurel forest ecology (columns 2–3) and morphological traits (columns 4–11).
Fig 3.
Optimisation of morphological traits to the mrca of the MLF species/sister in a radar plot.
In the outer circle laurophyllous traits are supported by BayesTraits analyses, in the inner circle they are rejected, in the middle circle the optimisation is ambiguous. The cutting value for the marginal probability: > 0.6, accepted; 0.6–0.5, ambiguous; < 0.4, rejected.
Fig 4.
Source areas of Macaronesian laurel forest taxa as indicated by Lagrange.
A) Proportion of area or area combinations as ancestral area for MLF based on relative probabilities over all taxa. B) Area reconstruction of each taxon with a likelihood > 10%. X-axis represents relative probabilities. Colours: (lilac) Macaronesia (Azores, Madeira, Canary Islands), (light blue) Europe incl. Mediterranean, (yellow) Asia, (dark red) North and South America, (green) Africa.
