Map of survey sites and eDNA concentration of water on the surface of headwater streams.

<p>At the sites on the expanded map (A1-A7, O1-O3), we directly captured the species using the hand-capture method (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0176541#pone.0176541.t001" target="_blank">Table 1</a>). N. D. means eDNA was not-detected.</p

The eDNA concentrations (in PCR reactions) from water samples collected from the surface and under stones at sites in the Akazai River.

<p>The bold line in the box indicates the median value. The upper and lower limits of the box and the whisker plots indicate the first and third quartiles and ± 1.5 × interquartile ranges, respectively. The red dots represent each data point.</p

Comparison of mean eDNA concentration of the water samples collected from the surface and under stones at sites in the Akazai River.

<p>The line shows 1:1 correlation for the log₁₀ concentrations.</p

The mean ΔCt value from internal positive controls by the PCR inhibition test for the samples collected from the surface and under stones at sites in the Akazai River.
