The impact of Pleistocene sea-level oscillations on plant genetic diversity: the case of the western Mediterranean endemic Carduncellus dianius (Asteraceae)

To what extent Pleistocene sea-level fluctuations have affected the genetic diversity of species is one of the current topics in biogeographical research. Carduncellus dianius is a Mediterranean narrow endemic species, restricted to < 20 populations distributed along coastal areas in Alicante (ma...

Carduncellus dianius is a Mediterranean narrow endemic species, restricted to < 20 populations distributed along coastal areas in Alicante (mainland eastern Iberian Peninsula) and on the island of Ibiza (Balearic Islands). To get insights into its evolutionary history and its genetic diversity and structure, we combined the analysis of molecular markers (three plastid DNA regions and AFLP) with ecological niche modelling. Results from dated phylogeographical analyses revealed that this species might have originated in the continental region during the early Pleistocene. The colonization of Ibiza could have occurred by a single long-distance dispersal event, with a subsequent back-colonization from the island to the same continental area of origin. These results corroborate the role of islands as sources for mainland colonization (biodiversity reservoirs) and as refugia during glacial periods. Notably, we detected that populations located on stable landmasses (i.e. not affected by sea rising during interglacial cycles) harboured significantly higher genetic diversity than those that were periodically submerged during the periods of marine transgressions. Our results point out sea-level fluctuations as a factor to be considered in phylogeographical studies focused on species distributed along coastlines.Financial support from the Spanish Ministerio de Ciencia e Innovación (Projects CGL2007-60781 and CGL2010/18631) and the Catalan government (‘Ajuts a grups consolidats’ 2009/SGR/439 and 2014/SGR/514 and 2017-SGR1116) is also acknowledged.Oxford University PressMinisterio de Ciencia e Innovación (España)Generalitat de CatalunyaLópez-Pujol, Jordi [0000-0002-2091-6222]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]2020202020192020info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Postprintinfo:eu-repo/semantics/acceptedVersionhttp://hdl.handle.net/10261/200141reponame:DIGITAL.CSIC.

Carduncellus dianius is a Mediterranean narrow endemic species, restricted to < 20 populations distributed along coastal areas in Alicante (mainland eastern Iberian Peninsula) and on the island of Ibiza (Balearic Islands).
