Goethite Reduction by a Neutrophilic Member of the Alphaproteobacterial Genus Telmatospirillum

Frontiers in Microbiology, 2019
In tropical iron ore regions, biologically mediated reduction of crystalline iron oxides drives ongoing iron cycling that contributes to the stability of surface duricrusts.

Contrasting greenhouse gas dynamics along a coastal‐to‐oligotrophic ocean continuum

Limnology and Oceanography Letters, Volume 10, Issue 6, Page 999-1010, December 2025.
Abstract The oceans play the dual role of carbon sinks and greenhouse gases (GHGs) sources in global climate change, but there are still gaps in understanding the GHG fluxes and regulation mechanisms across ecosystem scales. We conducted five cruises across a coastal‐to‐oligotrophic ocean continuum to evaluate the distributions and air‐sea exchange of ...

Growth of candidate phyla radiation bacteria in groundwater incubations reveals widespread adaptations to oxic conditions

Microbiome
Background The candidate phyla radiation (CPR) comprises a widespread but poorly understood group of bacteria with limited cultured representatives, largely due to their metabolic dependencies on microbial hosts.

Microbial Populations of Stony Meteorites: Substrate Controls on First Colonizers

Frontiers in Microbiology, 2017
Finding fresh, sterilized rocks provides ecologists with a clean slate to test ideas about first colonization and the evolution of soils de novo. Lava has been used previously in first colonizer studies due to the sterilizing heat required for its ...

An Efficient Quasi‐Monte Carlo Method for Concurrent Estimation of First‐Order and Total‐Effect Process Sensitivity Indices

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Developing and improving process‐based models requires identifying the importance and/or influence of various processes driving system behavior. In our recent studies, important processes are identified using first‐order process sensitivity index PSK (Dai et al., 2017, https://doi.org/10.1002/2016wr019715), and non‐influential processes are ...

Percent‐Level Copper Mineralisation Promoted by Copper‐Tolerant Iron‐Oxidising Bacteria in Circumneutral Mine Drainage

Environmental Microbiology, Volume 27, Issue 12, December 2025.
A neutrophilic Fe(II)‐oxidizing Gallionellaceae was isolated from circumneutral Cu mine drainage. It mediated Fe(III) biomineralization, resulting in pronounced Cu accumulation (up to 2 wt%) within the solid precipitates. ABSTRACT Geomicrobiology of copper (Cu) and iron (Fe) in circumneutral‐pH drainage from a Japanese Cu mine was investigated, with a ...

Ferromanganese nodules and micro-hardgrounds associated with the Cadiz Contourite Channel (NE Atlantic): Palaeoenvironmental records of fluid venting and bottom currents [PDF]

, 2012
Ferromanganese nodule fields and hardgrounds have recently been discovered in the Cadiz Contourite Channel in the Gulf of Cadiz (850–1000 m). This channel is part of a large contourite depositional system generated by the Mediterranean Outflow Water ...

Remagnetization of Lower Cretaceous Limestones in the Western Tethyan Himalaya and Its Tectonic Implications for the India‐Asia Collision

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract The drift history of the Tethyan Himalaya provides key constraints on the India‐Asia collision, Himalayan‐Tibetan orogenesis, and associated global climate change. Here we present rock magnetic, petrographic, geochronologic, and paleomagnetic results of the Bolinxiala Formation limestones in the western Tethyan Himalaya.
