Recovering Historical eDNA From Museum‐Preserved Filter Feeders via Non‐Destructive Metabarcoding

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT Recent technical advances have significantly enhanced the value of museum specimens for molecular research, with metagenomic and metabarcoding approaches expanding further the utility of museum collections. However, given the finite number of specimens, there is a critical need to move past destructive DNA extraction approaches and to explore ...

Prioritising research on endocrine disruption in the marine environment: a global perspective

Biological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Optimizing a Novel eDNA‐Based Framework for Reef Fish Biodiversity Monitoring Using an Autonomous Filtration System and in situ Nanopore Sequencing

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study presents a comprehensive eDNA metabarcoding protocol optimized for monitoring fish biodiversity in coral reefs and other remote marine environments. By combining an autonomous underwater filtration system, Oxford Nanopore sequencing, and a 12S reference database specifically developed for French Polynesia, the method enables efficient and ...

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 ...
