Abstract

An innovative technique based on the use of environmental DNA was proposed by Ficetola et al. (2008) for performing biodiversity assessment. Applications of this technique in rivers are still scarce, due to the limited knowledge on the dynamics of eDNA traces. Here, using the open source dataset by Carraro et al. 2020, we investigate the transport of eDNA. We first investigate the ability of eDNA to capture species abundance observed by classical methods via correlation measures. Finally, we setup a numerical simulation for evaluating the transport induced by advection and diffusion and the eDNA decay coefficient.
