Table 2 Results of AMOVA models on Psittacanthus schiedeanus populations with no groups defined a priori (a), and grouped into east and west of the Isthmus of Tehuantepec (b), three groups according to habitat distribution (c) or grouped into six groups according to geography and mountain range (d)

From: A mistletoe tale: postglacial invasion of Psittacanthus schiedeanus (Loranthaceae) to Mesoamerican cloud forests revealed by molecular data and species distribution modeling
