Investigating pelagic biodiversity and gelatinous zooplankton communities in the rapidly changing European Arctic: An eDNA metabarcoding survey

open access: yesEnvironmental DNA, Volume 6, Issue 3, May–June 2024.
In this study, we implement eDNA metabarcoding to investigate patterns of pelagic diversity in the European Arctic. We successfully detected a wide range of taxa belonging to the marine metazoan and gelatinous zooplankton communities. We demonstrate vertical patterns of diversity as well as relationships between taxa and water mass indicators such as ...

Autonomous eDNA collection using an uncrewed surface vessel over a 4200‐km transect of the eastern Pacific Ocean

open access: yesEnvironmental DNA, Volume 6, Issue 1, January–February 2024.
An uncrewed surface vessel and an automated eDNA sample collection device were used to obtain eDNA samples over a 4200‐km, 29‐day voyage in the eastern North Pacific Ocean. The results of the study revealed important technical considerations for acquiring samples autonomously and highlight how these platforms can increase the accessibility of obtaining
