This tool has been developed in the field of ...We tested the following hypotheses: (1) eRNA degrades faster than eDNA; (2) eRNA will only be detected during the shedding/release phase due to its rapid decay, (3) concentration of nucleic acid released into the water will depends on the biology of organism (e.g. the surface area), and (4) eDNA, but not eRNA, will accumulate in the biofilms ...Environmental DNA concept has been started practically since the year 1980 in marine sediments for detection and in field characterization of bacterial community (Ogram et al. 1987).First eDNA was determined in dissolved condition within the aquatic environments (DeFlaun et al. 1986) and it was quantified by advanced fluorescence …Environmental DNA (eDNA) monitoring is a novel molecular technique to detect species in natural habitats. Many eDNA studies in aquatic systems have focused on lake or ponds, and/or on large vertebrate species, but applications to invertebrates in river systems are emerging. ...
