Description
Anne Chenuil and co-authors compare, in a 2026 field study across ten northwestern Mediterranean sites, ways of monitoring sea life that settles on standardized reef structures left in the water. Photographs of each structure face were matched against DNA barcoding of organisms collected face by face, instead of pooling everything together.
DNA testing found roughly fifteen times more species per site than photographs and tracked distance and environmental patterns more sharply, thanks to finer identification. Photographs still added information on large organisms and surface cover. Keeping faces separate raised richness further. Marine monitoring teams get practical guidance on combining both methods instead of choosing one.
