Figure 2. The effects of water temperature and target gene on eDNA decay
rate constants. Left, middle, and right graphs show the linear
relationships between decay rate constants and temperature targeting all
genes (circle), mitochondrial DNA (square), and nuclear DNA (triangle),
respectively. Bold and dotted lines indicate the regression line and the
corresponding 95% CI estimated by lm and confintfunctions in R, respectively. R2 values of the linear
regressions are shown in the top-left corner of each figure, and the
asterisks indicate the statistical significance of the linear
regressions (*, P < 0.05; **, P <
0.01).
