Key message : We investigate patterns of phylogenetic diversity in relation to species diversity for European birds, mammals and amphibians to evaluate their congruence and highlight areas of particular evolutionary history. We estimate the extent to which the European network of protected areas (PAs) network retains interesting evolutionary history areas for the three groups separately and simultaneously. Phylogenetic (QEPD) and species diversity (SD) were estimated using the Rao’s quadratic entropy at 10′ resolution. We determined the regional relationship between QEPD and SD for each taxa with a spatial regression model and used the tails of the residuals (QERES) distribution to identify areas of higher and lower QEPD than predicted. QERES patterns across vertebrates show a strong spatial mismatch highlighting different evolutionary histories. Convergent areas represent only 2.7% of the Western Palearctic, with only 8.4% of these areas being covered by the current PAs network while a random distribution would retain 10.4% of them. QERES are unequally represented within PAs: areas with higher QEPD than predicted are better covered than expected, while low QEPD areas are undersampled. Although Europe has the world’s most extensive PAs network, evolutionary history of terrestrial vertebrates is unequally protected. The challenge is now to reconcile effective conservation planning with a contemporary view of biodiversity integrating multiple facets.
Spatial distribution patterns of species diversity (SD, left column), phylogenetic diversity (QEPD, middle column) and the residuals (QERES, right column) from the spatial regression between QEPD and SD for mammals and birds. For SD, low to high values are represented by a green colour gradient from soft to dark green, the QEPD follows a yellow to red gradient for increasing values of QEPD and for QERES values, the blue colours depict negative values of residuals (lower diversity than expected by the relationship between QEPD and SD) while the red colours depict positive residuals (higher QEPD than expected).
