Advancing species distribution modeling with multispecies eDNA metabarcoding: the case of the Atlantic bluefin tuna (Thunnus thynnus) in the Gulf of St. Lawrence (Canada)

Key Points

• Species distribution modeling improved with eDNA metabarcoding techniques, enabling better tracking of Thunnus thynnus populations.
• The study highlights the potential of eDNA to identify species presence, which can transform conservation efforts in the Gulf of St. Lawrence.
• Incorporating eDNA methods drives more accurate ecological modeling, bridging gaps in traditional survey approaches.
• Findings suggest that these advanced methods may enable broader ecological applications, although further validation is needed.
