Influence of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica [PDF]

, 2014
Archaea are the least understood members of the microbial community in Antarctic mineral soils. Although their occurrence in Antarctic coastal soils has been previously documented, little is known about their distribution in soils across the McMurdo Dry ...

Intact Polar and Core Glycerol Dibiphytanyl Glycerol Tetraether Lipids of Group I.1a and I.1b Thaumarchaeota in Soil

, 2012
Ecological studies of thaumarchaeota often apply glycerol dibiphytanyl glycerol tetraether (GDGT)-based intact membrane lipids. However, these components have only been characterized for thaumarchaeota from aquatic environments.

Possible mechanisms of Cdv-based cell division in Crenarchaeota, Thaumarchaeota and Asgard.

, 2022
Proteins are displayed as sets of building blocks as in Fig 2. Importantly, these mechanisms are not results of mathematical modelling, but are a qualitative explanation based on PPI networks (S1 Fig).

Thermoplasmatales and Methanogens: Potential Association with the Crenarchaeol Production in Chinese Soils

Frontiers in Microbiology, 2017
Crenarchaeol is a unique isoprenoid glycerol dibiphytanyl glycerol tetraether (iGDGT) lipid, which is only identified in cultures of ammonia-oxidizing Thaumarchaeota. However, the taxonomic origins of crenarchaeol have been debated recently. The archaeal

Diversity and seasonal dynamics of airborne archaea [PDF]

Biogeosciences, 2014
Archaea are widespread and abundant in many terrestrial and aquatic environments, and are thus outside extreme environments, accounting for up to ~10% of the prokaryotes.

Soil microbial diversity: The hidden wealth of sustainable farming

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Soil harbors diverse microbial communities that are fundamental to soil health and agricultural sustainability. Despite their ecological and agronomic importance, these communities remain underutilized as biological resources for improving crop production.

LIPOTHERM: A Calibration Framework for GDGT Paleothermometry Based on Machine Learning

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract SST reconstruction from glycerol dialkyl glycerol tetraethers (GDGT) preserved in marine sediments is an important tool in quantitative paleoclimatology. These reconstructions require calibration frameworks that provide mapping between sediment GDGT data and temperature values.

Substrate pulses as a selection factor for clades of marine Thaumarchaeota

, 2023
Abstract Oxidation rates of N supplied as ammonium (AO) or urea (UO) by Thaumarchaeota-dominated nitrifying communities in samples of aerobic waters from continental shelf and slope waters of the Southern Ocean west of the Antarctic Peninsula were inhibited by substrate amendments in the low nM range.

Light and temperature control the seasonal distribution of thaumarchaeota in the South Atlantic bight [PDF]

The ISME Journal, 2018
Abstract Mid-summer peaks in the abundance of Thaumarchaeota and nitrite concentration observed on the Georgia, USA, coast could result from in situ activity or advection of populations from another source. We collected data on the distribution of Thaumarchaeota, ammonia-oxidizing betaproteobacteria (AOB), Nitrospina, environmental ...

AllIGATR: A Multi‐Dimensional Approach for Marine Archaeal Lipid‐Based Paleothermometry

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract Archaeal glycerol dibiphytanyl glycerol tetraether membrane lipids (GDGTs) are ubiquitous in marine sediments. The number of ring structures in six specific GDGTs varies with seawater temperature, leading to their use in paleothermometry. GDGT temperature dependence is typically quantified in TEX86.
