Bark‐associated yeasts and their potential role as tree carbon sink at the treeline of the southern Andes

Plant Biology, Volume 28, Issue 6, Page 2054-2064, October 2026.
In the southern Andes, Nothofagus pumilio shows elevational decreases in the concentrations of carbon reserves which are the food of bark‐associated yeasts, suggesting that competition for carbohydrates between tree growth and bark‐associated yeasts may cause carbon shortages.

Cross‐Range Comparison of Supraglacial Microbial Communities Between Gongga and Gangrigabu Mountains, Southeast Tibetan Plateau

Ecology and Evolution, Volume 16, Issue 9, September 2026.
We investigated bacterial and fungal community distribution on supraglacial debris from two monsoon‐influenced mountain ranges (Gongga and Gangrigabu) using high‐throughput sequencing. Despite harsh, nitrogen‐limited conditions, diverse microbial taxa were detected, with clear distance–decay patterns and strong glacier‐specificity; heterogeneous ...

Unsaturated Fatty Acids in Antarctic Bacteria

Research Journal of Microbiology, 2016
Unsaturated Fatty Acids (UFAs) play a vital role in membrane lipids fluidity which maintains its structural integrity and also, are nutritionally and pharmaceutically important. Fish and vegetable oils are the major sources of the so-called essential fatty acids required for normal physiological activities of the body.

Airborne bacterial populations above desert soils of the McMurdo Dry Valleys, Antarctica [PDF]

, 2014
Bacteria are assumed to disperse widely via aerosolized transport due to their small size and resilience. The question of microbial endemicity in isolated populations is directly related to the level of airborne exogenous inputs, yet this has proven hard

Antarctic soil microbiomes encode structurally conserved and phylogenetically diverse beta‐lactamases

iMetaOmics, Volume 3, Issue 3, September 2026.
An integrative metagenomic framework combining sequence, structural, and functional inference reveals a phylogenetically diverse and structurally conserved repertoire of putative beta‐lactamases across Antarctic soil microbiomes, with predominance of class A and subclass B3 enzymes and limited but detectable associations with mobile genetic elements ...

Carbon dioxide emissions of Antarctic tourism [PDF]

, 2011
The increase of tourism to the Antarctic continent may entail not only local but also global environmental impacts. These latter impacts, which are mainly caused by transport, have been generally ignored.

Viruses in the sediments around the trenches harbor diverse survival mechanisms

iMetaOmics, Volume 3, Issue 3, September 2026.
Deep‐sea trenches are the deepest and most isolated environments in the global ocean but the diversity and adaptation of the viral communities remain poorly characterized. In this study, 5563 viral operational taxonomic units (vOTUs) were identified from sediments of the Yap Trench and Western Caroline Basin.
