Evidence of global-scale aeolian dispersal and endemism in isolated geothermal microbial communities of Antarctica [PDF]

, 2014
New evidence in aerobiology challenges the assumption that geographical isolation is an effective barrier to microbial transport. However, given the uncertainty with which aerobiological organisms are recruited into existing communities, the ultimate ...

Exploring the Potential and Evaluating Hydrocarbon Degradation by Novel Antarctic Dietzia and Pusillimonas Isolates From a Pristine Environment

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
The Antarctic Dietzia and Pusillimonas isolates were tested for bioremediation applications. Genomic analyses revealed the potential to degrade complex organic compounds, potential virulence factors and resistance genes. Physiological assays showed a wide range of adaptation to abiotic factors and sensitivity to different groups of antibiotics ...

Freezing Tolerance of Thermophilic Bacterial Endospores in Marine Sediments

Frontiers in Microbiology, 2019
Dormant endospores of anaerobic, thermophilic bacteria found in cold marine sediments offer a useful model for studying microbial biogeography, dispersal, and survival.

Mid‐Proterozoic Transient Oxygenation Events Linked to Enhanced Continental Chemical Weathering: Evidence From Carbonate Lithium Isotopes

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Potential drivers disrupting mid‐Proterozoic (∼1.8–0.8 Ga) environmental stasis remain poorly constrained. Here we examined carbonate Li isotopes from the ∼1.44 Ga Tieling Formation, North China, to evaluate the effects of continental chemical weathering on coeval oxygenation.

Sampling across large-scale geological gradients to study geosphere–biosphere interactions

Frontiers in Microbiology, 2022
Despite being one of the largest microbial ecosystems on Earth, many basic open questions remain about how life exists and thrives in the deep subsurface biosphere.

A >70‐Myr‐Long Geomagnetic Field Reversal Hyperactivity Across the Ediacaran‐Cambrian Transition

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract The long‐term variation of the geomagnetic field is a key constraint for unraveling the geodynamo processes and the evolution of Earth's deep interior. However, the geomagnetic reversal pattern during the Ediacaran–Cambrian transition remains elusive. Here we present an integrated magneto‐ and cyclo‐stratigraphic study of a ∼1.8‐Myr‐long, late

Potentially bioavailable iron produced through benthic cycling in glaciated Arctic fjords of Svalbard

Nature Communications, 2021
The impacts of a melting Arctic on the biogeochemistry of marine ecosystems are unknown. Here, the authors investigate glacial input of iron to Svalbard fjords finding that reworking of glacial iron in fjord sediment is important to make iron ...

Magnetosome Gene Duplication as an Important Driver in the Evolution of Magnetotaxis in the Alphaproteobacteria [PDF]

, 2019
The evolution of microbial magnetoreception (or magnetotaxis) is of great interest in the fields of microbiology, evolutionary biology, biophysics, geomicrobiology, and geochemistry.

Desert pavements: A hidden key to Earth surface processes

Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.
Desert pavements are a global phenomenon in arid environments, representing one of the most extensive geomorphological and geoecological features on Earth. To a large extent, they determine the interplay of key processes governing current and past landscape dynamics.
