Although most eDNA research is focused on leveraging genetic diversity to identify taxa, some recent studies explored the potential these detect within‐species variation, allowing population assessments abundance estimates from samples.

Abstract We reviewed the current methodology and practices of DNA metabarcoding approach using a universal PCR primer pair MiFish, which co-amplifies short fragment fish (approx. 170 bp from mitochondrial 12S rRNA gene) across wide variety taxa. This method has mostly been applied to biodiversity monitoring environmental (eDNA) shed and, coupled with next-generation sequencing technologies, enabled massively parallel several hundred eDNA samples simultaneously. Since publication its technical outline in 2015, this widely used various aquatic environments around six continents, MiFish primers have demonstrably outperformed other competing primers. Here, we progress over last 5 years highlight some case studies on marine, freshwater, estuarine communities. Additionally, discuss applications non-fish organisms, single-species detection systems, quantitative monitoring, bulk than eDNA.

Abstract Environmental DNA (eDNA) has seen a massive increase in application freshwater systems with concurrent growth protocol developments and drive to gain better understanding of the ‘ecology’ eDNA. This raises question whether we are currently still an early, developmental phase eDNA-based assessments or already transitioning into more applied stage for biomonitoring. I conducted systematic literature review on 381 eDNA-focused studies targeting macro-organisms over last 5 years, assessing study goals, methods, target taxa design aspects. The results show biomonitoring-focused throughout while fraction investigating eDNA decreased. metabarcoding significantly increased applying qPCRs tentatively declined. A geographic inequality was observed concerning numbers goals biased towards global North. Descriptive increased, but in-field conventional methods combined revealed no trend. These shift application-focused work also reveal this field be developing. In transitional phase, practitioners need ensure consistency data comparability long-term monitoring programmes.
