Oceanographic heterogeneity facilitates gelatinous zooplankton niche space and diversity

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Gelatinous zooplankton serve diverse ecological roles in shelf food webs—from grazers to predators. However, their spatial niches are poorly resolved, especially at detailed taxonomic levels, due to conventional techniques that are unable to measure distributions at fine spatial scales.

Seismic Disturbance, Productivity and Depth Shape Hadal Benthic Habitats and Biodiversity in the Japan, Ryukyu and Izu‐Ogasawara Trenches (Northwest Pacific Ocean)

Journal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim This study characterises benthic habitats and associated biodiversity in three Japanese subduction trenches, and explores the effects of trench‐specific differences in large‐scale seismic events, disturbance and productivity regimes on habitat structure and assemblage composition.

Review of Eastern Adriatic Hydromedusae: Unravelling Two Centuries of Records

Journal of Marine Science and Engineering
The Eastern Adriatic Sea is biogeographically complex, yet knowledge of its hydromedusae is fragmented across two centuries of uneven sampling and shifting taxonomy.

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

Environmental 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

Environmental 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
