The Pyrenean desman (Galemys pyrenaicus) is a small semi-aquatic mammal endemic to the Iberian Peninsula certain populations of which are endangered. Partial genomic information obtained from a population inhabiting several rivers of the Iberian System enabled some crucial parameters to be inferred for studying the genetic health of the desmans, such as relatedness and inbreeding, as well as relatedness networks that offer information on contemporary dispersal. The results revealed low connectivity between rivers and a significant effect of some river barriers on inbreeding. These data can help design conservation plans aimed at improving connectivity between populations, one of the biggest problems of this species.
