From: Choice of primer pairs and PCR polymerase affect the detection of fish eDNA
Fish taxonomic diversity monitored by the eDNA technology in surface water samples. Occurrence frequency (a) and relative sequence reads (b) of each species among all 15 groups of primer pairs and DNA polymerases. The shapes represent different DNA polymerases, and the colors refer to different primer pairs. The bubble size reflects the relative sequence reads of each group, that is, the sum of sequence reads of three replicates in each group divided by the total sequence reads in all groups
