Revisando la clasificación infraespecífica de Xerodraba patagonica (Brassicaceae) bajo diferentes fuentes de evidencia



Palabras clave:

Cruciferae, límites de especies, Patagonia, Tribu Eudemeae


Xerodraba (5 spp.) es un género de Brassicaceae restringido a los Andes del Sur y la Patagonia, del cual X. patagonica incluye la subsp. patagonica y la subsp. pycnophylloides. Esta última ha sido reducida recientemente de especie a subespecie por su similitud morfológica con la primera. Sin embargo, para una clasificación taxonómica adecuada de estos nombres (dos especies, una especie con dos subespecies, o una especie sin subespecies), se necesitan estudios adicionales, realizando análisis de diferentes tipos de datos. Aquí, aportamos evidencias para una nueva clasificación de estos nombres contrastando los resultados obtenidos de diferentes análisis filogenéticos, de nicho ecológico y morfológicos. Para ello, analizamos árboles de genes y especies utilizando datos de nrITS y plástidos, comparamos el nicho climático y el rango geográfico de ambas subespecies, y analizamos la variación morfológica asociada a estos nombres. Basándonos en los resultados obtenidos, decidimos sinonimizar a la subsp. pycnophylloides con X. patagonica.
