Historical demography in Anadenanthera colubrina var. cebil (Leguminosae) from Argentina.Anadenanthera colubrina var. cebil is a South American native tree species which characterizes the Seasonally Dry Tropical Forests (SDTFs). These forests are in disjunct patches along the Neotropics.The influence of past climatic fluctuations on the current distribution of these forests deserves several interpretations because the tropical climatic conditions were unstable during Cenozoic. The aim of thisstudy is identify traces of demographical-historical events on current patterns of chloroplastic genetic variation in Argentinean natural populations of A. colubrina var. cebil in order to make inferences aboutthe temporal development of these forests. Population genetic and demographic analyses from genetic variation in three chloroplastic loci were performed. The current distribution of chloroplastic haplotypes ofA. colubrina var. cebil shows clear traces of historical fragmentation between the nuclei of these forests.The Andean Piedmont nucleus maintains traces of later expansion after it arrives to the region, whereas the Misiones nucleus shows historical stability. Anadenanthera colubrina var. cebil es una especie nativa sudamericana que caracteriza a los Bosques Secos Estacionales Neotropicales, los cuales se presentan en parches disyuntos dispersosa lo largo del Neotrópico. La influencia de las fluctuaciones climáticas del pasado sobre la distribución actual de dichos bosques ha merecido diferentes interpretaciones, debido a que se postula que lascondiciones climáticas tropicales no fueron estables durante el Cenozoico. El objetivo de este estudio es identificar rastros de eventos demográfico-históricos sobre los patrones contemporáneos de la variación genética cloroplástica en poblaciones naturales argentinas de A. colubrina var. cebil, al efecto de hacer inferencias acerca del desarrollo temporal de estos bosques en nuestro país. Se realizaron análisis genético poblacionales y demográficos a partir de la variación genética identificada mediante tres locimicrosatélites cloroplásticos. La distribución contemporánea de haplotipos cloroplásticos de A. colubrina var. cebil retiene rastros de la fragmentación histórica entre los núcleos de estos bosques, mientras que el núcleo Pedemontano Subandino retiene rastros de una expansión posterior a su llegada a la región en tanto que el núcleo Misiones presenta estabilidad histórica.
