Depositional History of the Namibian Mud Belt Reveals Late Holocene Weakening of the Benguela Coastal Current

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract We investigate late Holocene changes in the northern Benguela Upwelling System using a multi‐proxy approach on shallow shelf deposits from the Namibian mud belt. Three sediment cores characterized by organic carbon‐rich, anoxic, and partly gas‐bearing sediments were retrieved along a sampling transect at 23°S in August 2019.

Automated Daily Measurements of Soil Pore Space CO2 and O2: Signals Revealing Soil Physical and Biogeochemical Processes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract There is a need to understand and monitor active soil processes in the field; however, it is challenging to observe and separate co‐occurring belowground processes. High precision monitoring of soil pore space gases is a potentially powerful approach, complicated by the variety of biological and physical processes that impact gas.

Prokaryotic Novelty and Metabolic Diversity in the Tagoro Shallow Hydrothermal System (Canary Islands, Spain)

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Hydrothermal activity at the Tagoro submarine volcano shapes distinct epipelagic and benthic prokaryotic communities. Microbial diversity decreases towards vent sources, yet novel taxa dominate and potentially contribute to iron, nitrogen, sulphur and methane cycling in this shallow hydrothermal system with high unexplored microbial diversity ...

Red to Green: A Lipid Biomarker Record of Tonian‐Ediacaran Algae in Siberia

Geobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT Multiple lines of evidence point to a major diversification of Eukarya in the late Tonian period, ca. 800–720 Ma ago. Regular steranes, lipid biomarkers primarily sourced from eukaryotes, are first unambiguously reported from multiple sites. Here, we present lipid biomarker stratigraphic records from two drill‐cores from the Lena‐Anabar Basin ...

Species‐level controls of foliar methane and nitrous oxide fluxes: roles of traits and microbes in temperate trees

New Phytologist, Volume 251, Issue 6, Page 3221-3237, September 2026.
Species‐level variation in temperate tree foliar greenhouse gas exchange, showing consistent foliar CH4 uptake, N2O emission, stronger CH4 uptake in fall leaves, and contrasting methanotroph communities between the high‐CH4‐oxidizing species Tilia americana and the low‐CH4‐oxidizing species Prunus virginiana. Summary The contribution of tree foliage to
