Figure 3. The effects of water source and target gene on eDNA decay rate constants. Left, middle, and right graphs show the boxplots of eDNA decay rate constants targeting all genes, mitochondrial DNA, and nuclear DNA, respectively. In each graph, decay rate constants derived from artificial water, freshwater, and seawater are shown in white, bright grey, and dark grey, respectively. Note that no study described eDNA decay rate constants using a nuclear DNA marker and freshwater samples.
