Development of eNA Sampling for Early Detection of Pathogens in On‐Farm Water Sources

Environmental DNA, Volume 8, Issue 2, March/April 2026.
We compare four water‐sampling methods for detecting microbial and viral eNA in livestock troughs and show all approaches effectively recover community profiles, supporting flexible, field‐ready surveillance of livestock pathogens. ABSTRACT Early detection of livestock pathogens is critical for mitigating risk and implementing timely control or ...

Evaluating eDNA Metabarcoding Techniques for Pollinator Community Assessment in a Field and Controlled Experiment

Environmental DNA
Pollinators play a critical role in ensuring the stability of food systems, yet their populations are in decline. To better understand and promote pollinator biodiversity, this study explored the use of environmental DNA (eDNA) metabarcoding techniques ...

Mapping Biodiversity Coast‐to‐Coast‐to‐Coast Across Canada's Three Oceans Using eDNA Metabarcoding

Environmental DNA
Marine biodiversity worldwide is rapidly declining, and nowhere is this more evident than in coastal ecosystems where the impacts of climate change and anthropogenic activities concentrate.

Environmental DNA Reveals Diverse and Depth‐Stratified Biodiversity in East Indian Ocean Submarine Canyons

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Environmental DNA metabarcoding reveals diverse animal communities across Cape Range and Cloates submarine canyons off Western Australia. Two assays detected 234 species spanning 125 families across 11 phyla, highlighting canyon‐specific assemblages and demonstrating the value of eDNA for establishing biodiversity baselines in remote and poorly ...

Putting eDNA to the test: A field comparison of eDNA metabarcoding to established protocols for assessing biodiversity in Missouri's Ozark Highland streams

Environmental DNA
Aquatic biodiversity monitoring to inform conservation and management efforts in‐stream systems has increasingly begun to incorporate environmental DNA (eDNA)‐based sampling methods.

Novel Assay for Endangered Hong Kong Grouper (Epinephelus akaara) to Assess eDNA Shedding, Decay, and Population Status

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Novel species‐specific eDNA qPCR assay for endangered Hong Kong Grouper (Epinephelus akaara) reveals low shedding rates and rapid decay. Rare, trace detections across Hong Kong waters confirm population rarity, demonstrating eDNA as a powerful non‐invasive tool for monitoring threatened marine fishes. ABSTRACT The Hong Kong Grouper (Epinephelus akaara)

Contaminant‐Driven Modulation of Environmental DNA and RNA in Aquatic Systems

Environmental DNA, Volume 8, Issue 2, March/April 2026.
This study investigates how lead (Pb) and polyethylene (PE) microbreads influence eDNA and eRNA signals in salmon and eels. While Pb exposure does not interfere with eNA signals, PE microbeads increase eRNA production and slow molecular degradation, prolonging the detection window of eNA in aquatic ecosystems.

Primer Length in Reverse Transcription Determines Biodiversity Recovery and Reproducibility in eRNA Metabarcoding

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Primer length for reverse transcription significantly affects eRNA‐based biodiversity recovery and community structure. Shorter primers, particularly N4 and N5, in random priming and medium‐length primers, particularly T20, in oligo(dT) priming demonstrate superior performance, especially in detecting the rare biosphere.

Improved COI taxonomic assignment workflow enhances detection of invertebrates in environmental DNA

Limnology and Oceanography: Methods, Volume 24, Issue 3, March 2026.
Abstract Environmental DNA (eDNA) metabarcoding is an increasingly popular and powerful tool in ecology, offering a non‐invasive method to assess biodiversity and monitor ecosystem health across diverse environments. While the mitochondrial cytochrome c oxidase subunit I (COI) gene is one of the most widely used markers for studying eukaryotic ...

Diversity and Potential Endemism of New Zealand Freshwater Rotifers Revealed Using Mitochondrial DNA Barcodes

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
Rotifers perform key functions in aquatic food webs and respond to environmental changes, thus providing sensitive indicators of water quality. However, rotifers are small, highly diverse, and difficult to identify for those lacking expertise. Monogononta are the largest taxonomic class of rotifers with over 1500 species described globally, and around ...
