Nitrous Oxide Accumulation in Braided Rivers Is Controlled by Interactions Between Seasons, Nitrate Availability, and Flow

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 11, November 2026.
Abstract Human activities have increased reactive nitrogen inputs to rivers, intensifying the emissions of nitrous oxide (N2O). However, riverine N2O saturation is difficult to predict because it is influenced by both reactive nitrogen availability, particularly nitrate (NO3−), and hydrology.

Agent‐Based Modelling of Microbialite Formation Through Sedimentation and Precipitation Dynamics

Geobiology, Volume 24, Issue 6, November/December 2026.
ABSTRACT Fossil microbialites resulting from the interplay of sedimentation and precipitation are among the oldest evidence of life on Earth and help geobiologists to interpret many sedimentary environments. However, the factors governing their internal structure and external morphology are still poorly understood.
