Abstract

A recent survey of the San Saba River in San Saba County, Texas, has yielded the first record in >30 years of a very recently deceased individual (i.e., with tissue present within the shell) of the unionid mussel Quadrula mitchelli (false spike). This very recently dead individual suggests that living populations of Q. mitchelli might still exist in the San Saba River. Our results provide evidence that surveys in remote areas may help to locate populations of rare species of unionid mussels.

Un muestreo recién del río San Saba en el condado de San Saba, Texas, ha dado el primer registro en >30 años de un individuo de mejillón unionido Quadrula mitchelli recientemente fallecido (es decir, con el tejido aún presente dentro de la concha). El encuentro sugiere que aún podrían existir más poblaciones actuales de Q. mitchelli dentro del río San Saba. Nuestros resultados rinden evidencia que muestreos realizados dentro de áreas remotas podrían ayudar a localizar poblaciones de especies raras del mejillón unionido.
