These authors therefore concluded: "to the extent that PAE [parsimony analysis of endemicity] and ecological grouping accurately reconstruct history, the forests analysed appear to be related by a unique, discernible history which is broadly concordant with the predictions of Pleistocene refuge theory" (p.
Notably, the historical climate appears to be an important determinant of richness in regions of marked climate changes and Pleistocene refuges, while the contemporary climate predicts the species richness across those regions with non-evident refuges in glacial times.
