eDNA as a cornerstone for holistic long-term observations of Arctic marine biodiversity across trophic levels, habitats, and spatio-temporal scales

Key Points

• eDNA monitoring reveals diverse Arctic marine biodiversity across multiple habitats and trophic levels.
• Key observations highlight diversity indices exceeding 50 species in various surveyed areas, indicating rich ecosystems.
• Assessments conducted across various habitats and spatio-temporal scales demonstrate the potential for eDNA technology to enhance conservation efforts.
• Findings support the use of eDNA for ongoing biodiversity monitoring, although further validation is required in different ecological contexts.
