The Effect of Temperature and Physical State of Water on the Frictional Properties of Chlorite‐Altered Basaltic Gouges (Krafla Geothermal Field, Iceland)

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Changes in the physical state of water may alter fault frictional properties in high‐temperature geothermal systems, yet they have been little studied. Here, we perform slide‐hold‐slide experiments to examine the frictional properties (frictional strength μss and frictional healing Δμ) of chlorite‐altered basalt from Krafla Geothermal Field ...

On the Assessment of Sinking Particle Fluxes From In Situ Particle Size Distributions

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract The biological carbon pump is a vital component of the global carbon cycle, particularly through the sinking of particulate organic carbon (POC) into the ocean interior. Particle size distribution (PSD) observations from the Underwater Vision Profiler (UVP) have been widely used to quantify sinking POC fluxes.

DNA Barcode Reference Library for European Ants: A Roadmap for Phylogeography and Species Discovery

open access: yesMolecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT DNA barcode reference libraries provide useful tools for specimen identification, highlighting potential new species and detecting introduced ones. Here, we present a comprehensive DNA barcode library for European ants and, in order to tackle the Linnean, Wallacean and Darwinian shortfalls of this group, we provide an updated checklist ...
