WebThe concentration of transported eDNA decreases with increasing distance from the source due to dilution and degradation (Goldberg et al., 2024). Having a high density right at the source and exponentially lower density at neighboring sampling stations can result in relatively lower sequence abundance in the latter samples (Zou et al., 2024). Webresorcinol, (II-13) (Figure II-6) using the pseudo-high dilution cyclization technique. Both II-14 and II-13 were dissolved in dimethylformamide (DMF) and added slowly (0.75 mL/h) to a mixture of potassium carbonate in a large volume of DMF at 110 oC. The reaction mixture was stirred for an additional five days after complete addition. The
