Albert Carné’s research focussed on a group of endemic reptiles of the Hajars mountain chain, in Oman. Biogeographically speaking, this is a very interesting area because of its topography, aridness, and isolation, and it actually hosts at least 20 endemic reptile species. In his study, Carné wanted to find out how such unique diversity could generate and be maintained through millions of years of evolution.
With such aim, he used two methods of ancestral reconstruction area to infer the origins of the different Hajars’ endemic reptile genera and their phylogeography within the mountain range. The main results of his dissertation support the notion that mountain chains constitute important centres of diversification in arid regions. In addition, it has demonstrated that arid mountains can act in parallel as montane museums, given that they accumulate diversity over time, and as species pump, as they disperse species into lowland areas.
The Origin: Revealing the diversity and biogeography of the endemic reptiles of the Hajar Mountains of south-eastern Arabia is the title of Carné’s dissertation, which he defended on September the 18th to obtain his MSc in Terrestrial Ecology and Biodiversity Management in the UAB. It was awarded a 10. The dissertation was developed under the direction of Salvador Carranza, principal investigator of the Systematics, Biogeography and Evolution of Reptiles Lab of the IBE.
