Millimetre‐Scale Stratification of Microbial Communities in Hydrothermal Sediments

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Zooming into the millimetre‐scale spatial distribution of organic molecules in hydrothermally impacted sediments using mass spectrometry imaging reveals a distinct lipid zonation with abrupt transitions at critical redox interfaces. This zonation reflects a pronounced stratification of diverse microbial communities and highlights surprisingly ...

Cryptic Carbon Cycle at Methane‐Seeps of the South China Sea: Evidence From Porewaters

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Anaerobic oxidation of methane (AOM) governs methane consumption at seeps, yet δ13C‐CH4 values in the sulfate‐methane transitions are commonly lower than predicted from preferential 12C utilization by methanotrophic archaea, suggesting the influence of a different methane source. To address this isotope discrepancy, we used high‐resolution ion

Overview of geothermal resource exploration and development in North Africa

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 673-685, December 2025.
This article reviews geothermal exploration in North Africa, highlighting key activities, government policies, and exploration findings across Mauritania, Morocco, Algeria, Tunisia, Libya, and Egypt. The region's substantial geothermal potential, driven by tectonic activity, positions it to play a significant role in the global geothermal energy ...

Identification of the dominant sulfate-reducing bacterial partner of anaerobic methanotrophs of the ANME-2 clade [PDF]

, 2010
The anaerobic oxidation of methane (AOM) with sulfate as terminal electron acceptor is mediated by consortia of methanotrophic archaea (ANME) and sulfate-reducing bacteria (SRB).

Habitat Diversity Sustains Ecosystem Functioning in Plateau Arid‐Region Wetlands

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Habitat diversity underpins both biodiversity and functional biogeochemical processes in plateau arid‐region wetlands, thereby stabilizing ecosystem functioning. These functionally complementary habitats collectively drive critical ecosystem processes.

Methane emission and consumption at a Noth Sea gas seep (Tommeliten area) [PDF]

, 2005
The Tommeliten seepage area is part of the Greater Ekofisk area, which is situated above the Tommeliten Delta salt diapir in the central North Sea (56°29.90' N, 2°59.80' E, Norwegian Block 1/9, 75 m water depth).

Methane-fuelled biofilms predominantly composed of methanotrophic ANME-1 in Arctic gas hydrate-related sediments [PDF]

, 2019
Sedimentary biofilms comprising microbial communities mediating the anaerobic oxidation of methane are rare. Here, we describe two biofilm communities discovered in sediment cores recovered from Arctic cold seep sites (gas hydrate pingos) in the north ...

Spatial Heterogeneity in Methane Biogeochemistry and Prokaryotic Community Structure in Sub‐Arctic Waterbodies in Northern Canada

Environmental Microbiology, Volume 27, Issue 12, December 2025.
Prokaryotic communities and methane dynamics differed markedly across 16 sub‐Arctic waterbodies. Maximum depth and permafrost thaw emerged as key drivers, with non‐stratified thaw‐affected sites hosting distinct communities and elevated methane fluxes, highlighting their potential role as emerging hotspots of methane emissions.

Methanogenic capabilities of ANME-archaea deduced from C-13-labelling approaches

, 2013
Anaerobic methanotrophic archaea (ANME) are ubiquitous in marine sediments where sulfate dependent anaerobic oxidation of methane (AOM) occurs. Despite considerable progress in the understanding of AOM, physiological details are still widely unresolved ...
