  Thuiller et al. analyzed the consequences of anticipated climate change on
plant, bird, and mammal phylogenetic diversity (PD) across Europe. They
concluded that species loss will not be clade specific across the Tree of Life,
and that there will not be an overall decline in PD across the whole of Europe.
We applaud their attempt to integrate phylogenetic knowledge into scenarios of
future extinction but their analyses raise a series of concerns. We focus here
on their analyses of plants.
