Effect of eDNA metabarcoding temporal sampling strategies on detection of coastal biodiversity by Maelle Sevellec, Anaïs Lacoursière-Roussel, Eric Normandeau, Louis Bernatchez, Kimberly Lynn Howland

“…However, monthly sampling was the most efficient for capturing holistic biodiversity.DiscussionWe provide recommendations for optimal eDNA metabarcoding sampling design based on our observations. The study underscores the importance of understanding biological and physical factors altering eDNA detection to improve the efficiency of detecting and interpreting long-term eDNA changes.…”
