Nonetheless, their conservation has often been neglected in comparison to efforts directed towards other biomes. The distribution pattern of Anadenanthera colubrina (Vell.) Brenan var. cebil (Griseb) Altschul allows an adequate mapping of this biome. The main objectives of this work are to study the historical processes that determined the current distribution of A. colubrina var. cebil under the hypothesis that the demographic history of the remaining fragments of SDTFs in Argentina leads back to a single event of ancestral divergence, and identify Argentinean localities with priority for conservation. Plastid genetic diversity of A. colubrina var. cebil from northern Argentina is characterised using three plastid microsatellite loci. From this, genetic characterization, population genetics, and Bayesian inference were carried out. The results from approximate Bayesian computations show that the Misiones and Piedmont Subandean nuclei diverged from an ancestral population in the early Neogene while the Formosa population derived from the Misiones nucleus in the late Neogene. Two out of five locations from the Misiones nucleus and three of nine locations from the Subandean Piedmont nucleus are proposed as priority conservation areas."],"dc:format":["application\/vnd.openxmlformats-officedocument.spreadsheetml.sheet"],"dc:language":["eng"],"dc:type":"dataset","dc:rights":["info:eu-repo\/semantics\/restrictedAccess","Datos sujetos al derecho de propiedad intelectual"],"dc:relation":["info:eu-repo\/grantAgreement\/Universidad Nacional de Misiones\/16\/Q1151-PI","info:eu-repo\/grantAgreement\/Ministerio de Ciencia, Tecnolog\u00eda e Innovaci\u00f3n Productiva.
