Thermal stratification and fish thermal preference explain vertical eDNA distributions in lakes

Joanne Littlefair, Lee Hrenchuk, Paul Blanchfield, Michael Rennie & Melania Cristescu
Significant advances have been made towards surveying animal and plant communities using DNA isolated from environmental samples. Despite rapid progress, we lack a comprehensive understanding of the “ecology” of environmental DNA (eDNA), particularly its temporal and spatial distribution and how this is shaped by abiotic and biotic processes. Here, we tested how seasonal variation in thermal stratification and animal habitat preferences influence the distribution of eDNA in lakes. We sampled eDNA depth profiles of five...
