Abstract

Population Graphs includes network theory to infer the relationship among individuals or populations and their respective roles. The hypothesis for this work establishes that Argentinean natural populations of Anadenanthera colubrina var. cebil keep ancestral polymorphism as a consequence of continuous historical distribution of this species in South America. Network analyses were performed centered on individuals and populations using two different measures which integrate genetic information in terms of time and divergence history. These analyses allow us to conclude that the populations of A. colubrina var. cebil display geographical isolation even though they are historically related.
