This special issue contains 11 papers that review and advance the field of eDNA detection of vertebrates and other macroorganisms, including studies of eDNA production,... Below are multimedia items associated with eDNA and water quality. This fact sheet was created to help biologists and resource managers understand emerging methods for detecting environmental DNA and their potential application for inventorying and monitoring aquatic species. The performance score for each indicator against each criterion calculated as the product of these two values (compliance × weighting factor). 145, 65–75. Despite efforts to build standardized barcode reference libraries for many major animal and plant phyla (Ratnasingham and Hebert, 2010; Guillou et al., 2013; Quast et al., 2013) including recent pest-focused initiatives (Diaz et al., 2004; Dias et al., 2017), numerous gaps remain. 100, 370–382. Sci. An improved primer set and amplification protocol with increased specificity and sensitivity targeting the Symbiodinium ITS2 region.

Hereafter, we refer to biosecurity, as protection against any risk posed to economy, health through “biological harm” caused by introducing or spreading non-indigenous species (and other harmful organisms such as diseases) in the wild (Armstrong and Ball, 2005). Front. Therefore, despite the potential of eRNA metabarcoding for differentiating living biodiversity, for example, in bilge (Pochon et al., 2017) or ballast water (Darling and Frederick, 2017; Rey et al., 2018), it remains challenging and requires further dedicated research and technological advancements to facilitate its uptake for biosecurity applications. (2014, table 1) and the Web of Sci- Our approach is based on the method-related criteria adopted from existing indicator evaluation frameworks (e.g., ICES, 2013; Krause-Jensen et al., 2015; Queirós et al., 2016).

Therefore, surveillance of extensive geographic areas is often constrained by available resources and likely to be limited to rapid assessment surveys (Awad et al., 2014; Nall et al., 2015; Minchin et al., 2016).

Conserv. Total Environ. This has been found to be an effective way to determine presence or absence of newts, but there are some limitations that should be borne in mind and which we expand upon below. Costs and ecological value of eDNA-based methods have rarely been evaluated in tropical regions, where high species richness is accompanied by high functional diversity (e.g., the use of different microhabitats by different species and life stages).

PLoS Biol. One of the key limitation of most molecular methods is that they usually cannot provide exact measures of abundance and/or biomass information (Yu et al., 2012), although some methods have higher quantitative capacity (e.g., qPCR, ddPCR, PCR-free approaches) than others (e.g., end-point PCR, HTS metabarcoding; Dowle et al., 2016). doi: 10.3354/aei00182, Pawlowski, J., Lejzerowicz, F., Apotheloz-Perret-Gentil, L., Visco, J., and Esling, P.
