Effect of water temperature and fish biomass on environmental DNA shedding, degradation, and size distribution [PDF]

Ecology and Evolution, 2019
Environmental DNA (eDNA) analysis has successfully detected organisms in various aquatic environments. However, there is little basic information on eDNA, including the eDNA shedding and degradation processes.
