Population Genomics Unveils the Century-Old Invasion of the Seagrass Halophila stipulacea in the Mediterranean Sea

We apply double digest Restriction-site Associated DNA sequencing (ddRAD-seq) to discover single nucleotide polymorphisms (SNPs) in order to assess the genetic diversity and structure of H. stipulacea populations from its native (Red Sea) and exotic (Mediterranean) biogeographic range. The obtained provide first insights into the demographic history and genomic patterns underlying the colonization, establishment, and subsequent spread of H. stipulacea in the Mediterranean.
