The niche of higher plants: evidence for phylogenetic conservatism.
Prinzing, A., Durka, W., Klotz, S., Brandl, R.
A species' ecological niche depends on the species' adaptations to its present habitat, but also on the legacy from its ancestors. Most authors argue that such a phylogenetic niche conservatism is of
