Microbial endolithic community at Meteor Crater

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 955-962, June 2026.
Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

Importation of psychrotolerant fungi to Antarctic associated with wooden cargo packaging

, 2018
The harsh climatic conditions and low levels of human activity in Antarctica, relative to other regions, means few non-native species have established. However, the risk of introductions is becoming greater as human activity increases.

Seasonal Variability of Precipitation‐Associated Bioaerosols, Including Viruses, and Their Links to Cloud Ice Processes and Precipitation in a Coastal City

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Viruses constitute a significant subset of bioaerosols whose roles in cloud ice processes remain understudied. Continuous observations of viruses and total airborne microbes (TAMs) in precipitation were conducted in Qingdao from March 2024 to December 2025.

Determinants of Soil Microarthropod Community Biodiversity in the Svalbard High Arctic: Locality or Vegetation Community?

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Arctic ecosystems like Svalbard are rapidly changing, yet soil microarthropods remain difficult to monitor due to limited baseline data and demanding field and identification work. Using 172 soil samples from 33 localities, we tested whether vegetation maps could serve as proxies for soil microarthropod communities.

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

Three new Pseudogymnoascus species (Pseudeurotiaceae, Thelebolales) described from Antarctic soils [PDF]

IMA Fungus
The genus Pseudogymnoascus includes several species frequently isolated from extreme environments worldwide, including cold environments such as Antarctica. This study describes three new species of Pseudogymnoascus—P. russus sp. nov., P.

Surface slicks structure microbial and viral neuston in relation to biogeochemical conditions

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract The sea‐surface microlayer (hereafter microlayer), which forms the interface between the ocean and atmosphere, plays a key role in nutrient cycling and microbial dynamics. Coastal slicks, which are viscous and biogenic surface films, often serve as hotspots for microbial activity, yet their structure and interactions remain incompletely ...

Microbial community composition of transiently wetted Antarctic Dry Valley soils

, 2015
During the summer months, wet (hyporheic) soils associated with ephemeral streams and lake edges in the Antarctic Dry Valleys (DVs) become hotspots of biological activity and are hypothesized to be an important source of carbon and nitrogen for arid DV ...

A 13,000‐Year Record of the Southern Hemisphere Westerlies Inferred From Pollen and Plant Wax Isotopes From the South Atlantic

Paleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract We compare a new pollen record with pre‐existing plant‐wax isotope data from lacustrine sediments retrieved from Mt. Usborne, East Falkland. These records document variations in plant productivity, wind intensity, and moisture availability, to measure the influence of the Southern Hemisphere Westerlies (SHW) over the last 13,000 years.
