description Background and aims: Acacia furcatispina belongs to the subgenus Aculeiferum. Currently, there are no studies in population genetics in this species. The aim of this work was to investigate the genetic diversity, population structure and spatial genetic structure at fine scale (SGS) in Argentinean sample sites by means of molecular markers.Materials and Metods: Two sample sites of A. furcatispina were studied with the AFLP technique. Three primer combinations were selected revealing for this study.Results: The three primer combinations revealed a total of 121 AFLP bands. The percentage of polymorphic loci showed a mean value of 86.8 % and the mean heterozygocity was 0.33. The Bayesian analysis performed with software STRUCTURE detected three clusters (K= 3), corresponding one to Pasaje Pozo Zuni (PP) sample site and two for Cerro de la Gloria (CG) sample site, showing a subdivision of this last one (CG1 and CG2). The AMOVA showed that the great component of variability was represented within populations. The SGS detected significant structuration at short and middle distances in PP. Conclusions: Based on the results of the present work, we recommend to sample trees far apart 10 m to minimize the kinship between individuals. These results present the first study in genetic diversity, population structure and spatial genetic structure at fine scale in A. furcatispina and all the analyses made here result of interest for management and conservation of this species.

Introduccion y objetivos: Acacia furcatispina, pertenece al subgénero Aculeiferum. Actualmente no hay estudios sobre la diversidad y estructura genética de esta especie. El objetivo de este trabajo fue estudiar la diversidad genética, estructura poblacional, y la estructura genética espacial a escala fina (SGS) en localidades argentinas de esta especie. Materiales y Métodos: Se estudiaron dos localidades de la especie A. furcatispina mediante la técnica de AFLP. Se seleccionaron 3 combinaciones de cebadores. Resultados: Con las combinaciones de cebadores seleccionadas, se revelaron un total de 121 bandas. El porcentaje de loci polimórficos presentó un valor medio de 86,8 % y la heterocigosis 0,33. El análisis bayesiano STRUCTURE mostró que los individuos analizados pertenecen a tres grupos genéticos (K= 3), uno correspondiente a la localidad Pasaje Pozo Zuni (PP) y dos, a Cerro de la Gloria (CG), subdividida en dos poblaciones (CG1 y CG2). El AMOVA indicó que la mayor parte de la variabilidad se encuentra contenida dentro de las poblaciones. El análisis SGS detectó estructuración local significativa a cortas y medianas distancias en la población PP. Conclusiones: Basado en los resultados del presente trabajo, se recomienda muestrear árboles a más de 10 metros de distancia para minimizar el parentesco entre individuos. Estos resultados proveen el primer estudio acerca de la diversidad, estructura genética y estructura a escala espacial fina de Acacia furcatispina y todos los análisis realizados resultan de interés para el manejo y conservación de esta especie.
