Conservation implications of strong population structure despite admixture in the endangered seagrass Zostera capensis

Five populations of Zostera capensis were sampled across a region known to encompass a break between two major lineages in this species. A ddRAD genotyping and de novo assembly approach were used to call a suite of 4103 SNP loci, from which neutral and putative outlier loci were detected. Using these full, neutral and outlier loci datasets genomic diversity, population structure and admixture were investigated.
