Distribution of the seagrass Halophila stipulacea: a big jump to the northwestern Mediterranean Sea. Aquatic Botany 103465. https://doi.org/10.1016/j.aquabot.2021.103465 Comments: Considering the large area invaded at Cannes, the introduction seems to date back to a few years ago, which means that the species has endured at least one winter period. The Bay of Cannes is among the world's most highly-frequented places for luxury mega-yachts and cruise ships, especially from May to the end of August, and in particular during prestigious cultural events such as the Cannes Film Festival, when a large number of large ships moor there. Anchors are an effective mode of dissemination for NIS (Boudouresque and Verlaque, 2002, West et al., 2007) and are strongly suspected of being responsible for the dissemination of H. stipulacea (Lipkin, 1975; Ruiz and Ballentine, 2004, Gambi et al., 2009). |
