Geographical range and spatial structure of genetic lineages in Sophora linearifolia (Fabaceae), an endemic shrub of Central Argentina. A large number of endemic species occur in the Sierras of Córdoba and San Luis. A significant group of them shows a disjunct geographic distribution between these two mountain regions. Until the present study, there were none genetic studies that allow us to infer historical processes underlying this geographical pattern. For this purpose, we characterize the distribution area and phylogeographic patterns of Sophora linearifolia, across its geographic range which includes Sierras Chicas (SC) and Cumbres de Gaspar (CG) in Córdoba and in the southwesternarea of Sierras of San Luis (SL). We compared the current with the predicted species area of distribution using ecological niche modelling analysis. We also analyzed genetic variability and spatial structure of the DNA chloroplast marker trnH-psbA, and reconstructed the genealogical relationships among theretrieved haplotypes. Current and the predicted distribution agreed in showing a climatic/topographic disjunction between Sierras of Cordoba and San Luis hills, although the current distribution presents a disjunction between SC and CG in Córdoba, not shown in the potential distribution map. We obtained eight haplotypes with restricted distribution and low levels of genetic differentiation that were grouped into four phylogroups: SC, CG and two in SL. Our results indicate that S. linearifolia presents low dispersal ability and it would have recently diversified, suggesting a neoendemic taxon. |

Las sierras de Córdoba y San Luis albergan una gran riqueza de especies endémicas. Un grupo importante de ellas muestra una distribución disyunta entre ambas serranías. Hasta la actualidad no existían estudios genéticos que permitieran inferir procesos históricos asociados a este patrón. Con este propósito caracterizamos el área de distribución y el patrón filogeográfico de Sophora linearifolia, abarcando todo su rango geográfico que incluye las Sierras Chicas (SC) y las Cumbres de Gaspar (CG) en Córdoba y el suroeste de las Sierras de San Luis (SL). Contrastamos la distribución actual con la distribución predicha a partir del modelado del nicho ecológico. Analizamos el nivel de variabilidad genética, la estructuración espacial del marcador de ADN plastidial trnH-psbA y reconstruimos las relaciones genealógicas entre los haplotipos. La distribución actual y la predicha mostraron una disyunción entre Córdoba y San Luis, pero la distribución actual presentó una disyunción entre SC y CG que no fue modelada en la distribución potencial. Se obtuvieron 8 haplotipos de distribución restringida con bajos niveles de diferenciación genética agrupados en 4 filogrupos: SC, CG y dos en SL. Nuestros resultados indican que S. linearifolia presentaría baja capacidad de dispersión y que se habría diversificado recientemente, sugiriendo que se trataría de un neoendemismo.
