“…In regard to its conservation status, it has been listed under different conservation categories according to a variety of regional and global red lists ( Bilz et al, 2011 ; Domina, 2011 ; Rossi et al, 2013 ; Urbani, Calvia & Pisanu, 2013 ). Both species are conspicuous, tussock-forming plants, which are ecologically relevant as they are dominant and characteristic taxa in the plant communities where they live (phytosociological ranks: association, alliance, class; Molina, 1996 ; Navarro, Molina & Moreno, 2001 ; Rufo Nieto & De la Fuente García, 2011 ; Gianguzzi et al, 2013 ; Rodríguez-Guitián et al, 2017 ). Previous studies revealed a strong genetic structure in both species driven by geography, with distinct genetic clusters corresponding to disjunct populations ( Jiménez-Mejías et al, 2011 ; Benítez-Benítez et al, 2018 ).…”

Anticipating the evolutionary responses of species to ongoing climate change is essential to propose effective management and conservation measures. The Western Mediterranean Basin constitutes one of the hotspots of biodiversity where the effects of climate change are expected to be more dramatic. Plant species with ecological relevance constitute ideal models to evaluate and predict the impact of climate change on ecosystems. Here we investigate these impacts through the spatio-temporal comparison of genetic diversity/structure (AFLPs), potential distribution under different future scenarios of climate change, and ecological space in two Western Mediterranean sister species of genus Carex. Both species are ecologically key in their riparian habitats, but display contrasting distribution patterns, with one widespread in the Iberian Peninsula and North Africa (C. reuteriana), while the other (C. panormitana) is a restricted, probably endangered, Central Mediterranean endemic. At present, we found a strong genetic structure driven by geography in both species, and lower values of genetic diversity and a narrower ecological space in C. panormitana than in C. reuteriana, while the allelic rarity was higher in the former than in C. reuteriana subspecies. Future projections predict an overall dramatic reduction of suitable areas for both species under all climate change scenarios, which could be almost total for C. panormitana. In addition, gene diversity was inferred to decrease in all taxa, with genetic structure reinforcing in C. reuteriana by the loss of admixture among populations. Our findings stress the need for a reassessment of C. panormitana conservation status under IUCN Red List criteria and the implementation of conservation measures.
