Revealing Hidden Threats: Marine Invertebrate Invasions in the Banc d’Arguin National Park (PNBA), Mauritania, Explored Through DNA Barcoding

A groundbreaking study using DNA barcoding reveals hidden threats to the Banc d'Arguin National Park (PNBA) in Mauritania, uncovering marine invertebrate invasions that pose significant risks to its biodiversity. The research identified 17 species from three phyla—Cnidaria, Bryozoa, and Arthropoda—including several cryptic taxa, with evidence suggesting human-mediated introductions of hydroids, bryozoans, and barnacles from regions like Brazil and the Indo-Pacific. Notably, Amathia brasiliensis and Amathia cf. vidovici were recorded for the first time in West Africa, raising concerns about their ecological impact. The study highlights the vulnerability of the PNBA to exotic species introductions via international maritime traffic and fishing activities, emphasizing the need for urgent conservation measures and biosecurity protocols.
