    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

    Published 2025-02-01
    “…However, we have limited knowledge of whether samples collected during discreet temporal periods depict holistic ecosystem changes over longer time spans.MethodsHere, we show how eDNA community structure varies across repeated sampling events at different temporal scales ranging from years to months to days at an Arctic coastal site, Churchill (Canada), using metabarcoding analyses of water eDNA samples with four universal primer pairs (two primers in COI and two in the 18S rRNA).ResultsDaily variations were highly dynamic and less structured, likely due to the stochastic nature of estuarine ecosystems, but there was a clear annual consistency in eDNA communities with a high proportion of shared taxa between years. …”
