A combination of stabilizing selection and random walk are associated with phylogenetic signal in hard pines.

ABSTRACT:

Background and aims

Although phylogenetic niche conservatism is widely accepted, in many cases the cause of this conservatism is unclear. The presence of phylogenetic signal could extend to morphological and anatomical characters, chemical soil properties and DNA content. However, as sessile organisms, especially those that migrated toward drier or tropical conditions, are subject to environmental heterogeneity, phylogenetic signal in these characters could be explained by a combination of different evolutionary forces.

Methods

We assessed the phylogenetic signal in DNA content, chemical soil properties, climate and morphoanatomical characteristics, tested different evolutionary models and performed an ancestral state reconstruction in 30 species of hard pines geographically
