Understanding the population structure and demographics of <i>Q. suber</i> is essential in order to anticipate whether populations at greater risk and the species as a whole have the genetic background and reproductive dynamics to enable rapid adaptation. The genetic diversity of <i>Q. suber</i> has been subject to different studies using both chloroplast and nuclear data, but population structure patterns remain unclear. Here, we perform genetic analyses on <i>Q. suber</i> using 13 nuclear microsatellite markers, and analysed 17 distinct locations across the entire rangePeerJe13565https://www.ebi.ac.uk/biostudies/studies/S-EPMC9206845biostudies-literaturePopulation structure in <i>Quercus suber</i> L. revealed by nuclear microsatellite markers.PMC9206845Costa JGlushkova MPinto Ricardo CRibeiro CVarandas MPina-Martins FBatista DMatos JOliveira MVeloso MMSimoes FSousa FMiguel CPaulo OSfalsePopulation structure in <i>Quercus suber</i> L. revealed by nuclear microsatellite markers.<i>Quercus suber</i> L. is a sclerophyllous tree species native to the western Mediterranean, a region that is considered highly vulnerable to increased temperatures and severe dry conditions due to environmental changes.
