Microbial Community Dynamics in Early Tufa Biofilms

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
Microbial succession shapes the early development of tufa biofilms in karst freshwater systems, with prokaryotic communities stabilizing rapidly and microeukaryotes contributing to extracellular polymeric substance production and carbonate entrapment. Site‐specific hydrodynamics and organic inputs drive community specialization, ultimately influencing ...

Globally Mapping the Nitrogen Stable Isotope Ratios of Terrestrial Vegetation From 1984 to 2022

open access: yesEarth's Future, Volume 13, Issue 12, December 2025.
Abstract Nitrogen cycles control the structure, function, and composition of ecosystems globally. Despite their importance, our understanding of long‐term changes in global nitrogen cycles remains limited. The foliar nitrogen stable isotope ratio (δ15N) serves as a valuable metric for assessing changes in nitrogen cycling and potentially in plant ...

A Review of the Spatiotemporal Evolution of the High Arctic Large Igneous Province, and a New U‐Pb Age of a Mafic Sill Complex on Svalbard

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The High Arctic Large Igneous Province (HALIP) formed in the circum‐Arctic during the Cretaceous. The timing and duration of emplacement of these mafic magmas are important for understanding the climatic and environmental effects, yet many uncertainties remain. The dating methods used vary greatly between different regions.

Toward Reconstructing Mantle Convection Using a Minimum‐Continent‐Motion Reference Frame

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Studying geodynamic processes at the plate‐mantle interface requires knowledge of how plates move over and subduct into the mantle. The absolute motion of plates relative to the mantle since ∼120 Ma is classically estimated using hotspot tracks.
