dc.descriptionLa compleja topografía de los Andes ha facilitado múltiples eventos de diversificación promoviendo la diversidad de linajes en Suramérica. Sin embargo, poco se conoce sobre la divergencia causada por los Andes en artrópodos y en particular en arácnidos. En este estudio se evaluó la conectividad genética de poblaciones de la araña semiacuática Ancylometes bogotensis (n=42), empleando un marcador nuclear y uno mitocondrial. Ancylometes bogotensis se recuperó dentro de la familia Ctenidae, formando dos clados fuertemente estructurados por la cordillera oriental colombiana sin evidencia de flujo genético entre ellos. La diferenciación dentro de esta especie coincide con el levantamiento de dicha cordillera (~2.76Ma). Por lo tanto, este caso se constituye en uno de los pocos casos en artrópodos donde se documenta divergencia por vicarianza continental.spa
dc.description.abstractAndean topography promoted lineage diversification in South America. However, there is a lack of evidence about its effect in arthropod divergence, especially in arachnids. In this study, the genetic connectivity among populations of the aquatic spider Ancylometes bogotensis (n=42) was tested using mitochondrial and nuclear DNA. A bogotensis was monophyletic and nested inside the Ctenidae family. This species was splitted in two divergent and structurated clades separated by the eastern cordillera of the Colombian Andes without gene flow. Divergence time for these clades were ~2.76Ma, matching the geological uplift of this cordillera. This study constitutes one of the few cases, where divergence caused by vicariance shaped the genetic diversity in an arthropod lineage.spa
