The lesser horseshoe bat (Rhinolophus hipposideros) has been documented as one of the most rapidly declining bat species in Europe, even with local extinctions in the northern range of its distribution. But this pattern observed all across Europe seems not to be pertinent in Galicia, a region placed in NW Spain, where the species is abundant and well distributed.
The main questions of my doctoral thesis are:
1) What's the origin of the galician populations? Galician biodiversity has three main sources: Eurosiberian, Mediterranean and Relict. To test the latter is of great interest since the presence of relict lineages could demonstrate the role of Galicia as a glacial refugio for this species during the last ice age.
2) How was the process and which elements were involved in the history of the species? The question is if Galicia was the origin of a colonization or was colonized, and if was so, how and when did it happen? Is the current abundance due to a demographic expansion of the populations or just a slower decline, compared with what is happening in other regions? Have the climate changes or the human-induced landscape transformations something to do with the ongoing processes?
3) What are the consequences of the recent changes, not only on the genetic structure, but also on the phenotype such as echolocation calls? The hypothesis I work with is that the genetic structure entails a differentiation in echolocation calls among the extant populations.
My research is entirely funded by the Barrié de la Maza Foundation.
