    • East is East and West is West: Population genomics and hierarchical analyses reveal genetic structure and adaptation footprints in the keystone species Paracentrotus lividus (Echinoidea) 

      Carreras, Carlos; García-Cisneros, Alex; Wangensteen Fuentes, Owen Simon; Ordóñez, Victor; Palacín, Creu; Pascual, Marta; Turon, Xavier (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-14)
      <i>Aim</i> - The Atlanto‐Mediterranean edible purple sea urchin, <i>Paracentrotus lividus</i>, is a commercially exploited keystone species in benthic communities. Its browsing activity can deeply modify the littoral landscape, and changes in its abundance are of major conservation concern. This species is facing nowadays contrasting anthropogenic pressures linked to predator release, exploitation ...

    • Spatio-temporal patterns of genetic variation in Arbacia lixula, a thermophilous sea urchin in expansion in the Mediterranean 

      Pérez-Portela, Rocío; Wangensteen Fuentes, Owen Simon; García-Cisneros, Alex; Valero-Jiménez, Claudio; Palacín, Creu; Turon, Xavier (Journal article; Tidsskriftartikkel, 2018-06-14)
      The genetic structure of 13 populations of the amphiatlantic sea urchin <i>Arbacia lixula</i>, as well as temporal genetic changes in three of these localities, were assessed using ten hypervariable microsatellite loci. This thermophilous sea urchin is an important engineer species triggering the formation of barren grounds through its grazing activity. Its abundance seems to be increasing in most ...

    • The Two Sides of the Mediterranean: Population Genomics of the Black Sea Urchin Arbacia lixula (Linnaeus, 1758) in a Warming Sea 

      Carreras, Carlos; Ordóñez, Victor; García-Cisneros, Alex; Wangensteen, Owen S.; Palacín, Creu; Pascual, Marta; Turon, Xavier (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-10)
      Global environmental changes may have a profound impact on ecosystems. In this context, it is crucial to gather biological and ecological information of the main species in marine communities to predict and mitigate potential effects of shifts in their distribution, abundance, and interactions. Using genotyping by sequencing (GBS), we assessed the genetic structure of a keystone species in the ...
