Excerpt
Environmental DNA (eDNA) analysis has been widely used to investigate the distribution and abundance/biomass of macro-organisms, and during the past decade, the application of eDNA-based biomonitoring has gained increasing interest (Goldberg et al.
2015; Thomsen and Willerslev
2015; Tsuji et al.
2019; Doi et al.
2021). eDNA, which comprises DNA fragments released by organisms into the environment is believed to be derived from mixtures of feces, skin cells, mucus, and secretions. eDNA techniques can be used to analyze DNA collected directly from environmental sources, such as water, soil, and air (Goldberg et al.
2015). With respect to water bodies, these methods have been applied in monitoring multiple species inhabiting a range of limnologic habitats, including rivers, lakes, and ponds, and eDNA detection and quantification have been performed for a diverse range of taxa, including fish, aquatic plants, mollusks, insects, crustaceans, reptiles, amphibians, birds, and mammals (Tsuji et al.
2019). …
