Assessment of Preservation and Extraction Methods for Environmental DNA in Sediments

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
We assessed how different preservation methods (freezing, room temperature, silica gel, Longmire buffer) affect eDNA metabarcoding results for bacterial, fungal, microeukaryotic, and metazoan communities in marine and freshwater sediments. Results demonstrate taxonomic‐ and habitat‐specific responses to preservation methods, providing evidence‐based ...

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

open access: yesJournal 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.

Pan‐Arctic distribution modeling reveals climate‐change‐driven poleward shifts of major gelatinous zooplankton species

open access: yesLimnology and Oceanography, Volume 69, Issue 6, Page 1316-1334, June 2024.
Abstract Anthropogenic activities, including climate change, are hypothesized to cause increases in gelatinous zooplankton population sizes and blooms. In the most rapidly changing ecosystem, the Arctic Ocean, this hypothesis has not yet been verified, and gelatinous zooplankton is commonly excluded from large‐scale modeling studies. Our modeling study

Modelling of Arctic gelatinous zooplankton distribution and abundance based on data from pelagic video transects in Fram Strait

open access: yes, 2021
Global warming in the Arctic region causes alterations in the composition and structure of marine communities. Such changes are particularly pronounced in the transitional zones such as Fram Strait where the increased inflow of warm Atlantic waters ...

Phylogenetics of Trachylina (Cnidaria: Hydrozoa) with new insights on the evolution of some problematical taxa [PDF]

open access: yes, 2017
Some of the most interesting and enigmatic cnidarians are classified within the hydrozoan subclass Trachylina. Despite being relatively depauperate in species richness, the clade contains four taxa typically accorded ordinal status: Actinulida ...
