Metabarcoding and eDNA for insect conservation

Environmental DNA (eDNA) samples and metabarcoding studies have emerged as transformative sampling methods and techniques with potential in the field of insect conservation. eDNA refers to genetic material shed by organisms into their environment. By extracting and sequencing this DNA, it is possible to detect the presence of target species without the

Comparative Efficiency of eDNA, Camera Traps and Scat Surveys to Detect a Semi‐Aquatic Mammal Across Multiple Catchments

Animal Conservation, EarlyView.
Monitoring semi‐aquatic mammals is essential for their conservation, but it is made difficult by their elusive lifestyle and generally low abundance. Eurasian otter (Lutra lutra) monitoring has traditionally relied on scat surveys, but eDNA and camera‐trapping are emerging as promising alternatives.

Testing the utility of eDNA metabarcoding for studying groundwater biodiversity [PDF]

, 2022
Subterranean habitats are among the least explored environments on our planet and their fauna remains inadequately known. Fortunately, the rapid development of methods in modern biology can help expand our understanding of cave biodiversity. We tested the utility of environmental DNA (eDNA) to identify subterranean communities in Plitvice Lakes ...

Enhancing fish community monitoring at a cabled observatory by combining environmental DNA and imaging analysis

Journal of Fish Biology, EarlyView.
Abstract Cabled multiparametric observatories are sustaining ecological monitoring by collecting long‐term real‐time biological and environmental data. Here, we investigated fish communities by sampling environmental DNA (eDNA) over 4 days near the multiparametric cabled video‐observatory OBSEA (Northwestern Mediterranean Sea).

Comparison Between Environmental DNA Metabarcoding and Traditional Survey Method to Identify Community Composition and Assembly of Stream Fish

Ecology and Evolution
Environmental DNA (eDNA) metabarcoding has been widely used in freshwater systems, contributing to the advancements in the monitoring of fish diversity and community species composition. Nevertheless, the accuracy and reliability of eDNA metabarcoding in

Proteinase K is not essential for marine eDNA metabarcoding

Environmental DNA
AbstractProteinase K (ProK) is regarded as an essential ingredient in most DNA extraction protocols for protein‐rich sample types such as tissue, blood, and mucus. However, ProK is expensive and may be unnecessary when samples are protein‐limited, such as environmental DNA (eDNA) from oligotrophic seawater.

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Environmental DNA metabarcoding for biodiversity monitoring of a highly diverse tropical fish community in a coral reef lagoon: Estimation of species richness and detection of habitat segregation

Environmental DNA, 2021
An environmental DNA (eDNA) metabarcoding approach has been widely used for biodiversity monitoring of fishes, although it has rarely been applied to tropical and subtropical aquatic ecosystems, where species diversity is remarkably high.

Improving Biodiversity Inventories Based On Metabarcoding Of Edna

, 2018
ATLAS work package 4 presentation at ATLAS 3rd General Assembly In the framework of ATLAS, we planned to sample sediment and water to test our ability to produce biodiversity inventories based on environmental DNA. During Medwaves cruise, we sampled sediment from four sites spanning from the Mediterranean to the Azores, with the objective to ...

Quantitative insights into the spatio‐temporal variation of Atlantic salmon (Salmo salar) biomass in a river catchment using eDNA metabarcoding

Journal of Fish Biology, EarlyView.
Abstract Effective species conservation and management requires comprehensive biomonitoring, enhanced by combining traditional and newer methodologies, such as environmental DNA (eDNA) analyses. A seasonal pulse of spawning adult Atlantic salmon (Salmo salar) was detected by normalised eDNA 12S reads from metabarcoding, which facilitated estimation of ...
