individuals from the Yungas, and the second group integrated by the clusters 1, 2,
and 5 containing all individuals from the Alto Paraná Rainforest. Furthermore, chloroplast genome keeps valuable information about historical population changes in
this species emphasizing the role of ancient fragmentation in the species distribution (Barrandeguy et al. 2014).
Historical divergence in A. colubrina var. cebil was studied by means of an
intronic region of chloroplast DNA allowing to detect genetic differences between
the distribution fragments of this species and contextualize them in a time frame
