During this time, the minor Smithian-Spathian extinction occurred, further delaying the biotic recovery of this epoch. One mechanism linked to the slow recovery is widespread marine anoxic conditions, but the spatiotemporal changes to anoxia following the mass extinction remain poorly constrained. Here, we utilized local and global redox-sensitive metal proxies to track variations in (de-)oxygenation at Wallenbergfjellet, a section in Spitsbergen, Arctic Norway. Local proxies (e.g., Fe speciation and trace metal concentrations) indicate basinal anoxia and possibly euxinia prevalent in the Boreal Ocean during this interval. Importantly, thallium isotopes, a global paleoredox proxy sensitive to Mn oxide burial, have not previously been applied to the Early Triassic recovery interval that followed the end-Permian mass extinction, though basinal restriction may limit geographic extent of interpretations. Our results show a shift in ε²⁰⁵Tl values from ~ -4.0 in the Smithian to ~ -2.0 at the Smithian-Spathian boundary (SSB), consistent with a rapid expansion of global anoxia coincident with the boundary extinction. A rapid perturbation in thallium isotopes at the SSB (from -4.0 to -2.0 ε-units) indicates this interval experienced an expansion of anoxic conditions that can be linked to the minor extinction event during the recovery interval following the end-Permian mass extinction. This suggests that global anoxia persisted throughout the Early Triassic and contributed to delayed biotic recovery, with the SSB representing a major intensification of reducing conditions.</p>","PeriodicalId":173,"journal":{"name":"Geobiology","volume":"24 5","pages":"e70062"},"PeriodicalIF":2.7,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13539283/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148878639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microcharacterisation involving optical microscopy, combined scanning electron microscopy and energy dispersive spectroscopy (SEM-EDS) and nanoscale secondary ion mass spectroscopy (NanoSIMS), was undertaken to identify microbial textures and relics in stromatolite samples. Microbial textures identified are micritic streaky and micropeloidal (grumous) microstructures as well as microcolumns, micritic threads and micritised tubular outlines resembling the <i>Girvanella</i> calcimicrobe. Within these microbial textures, multiple biotic components are discerned, including intact and flattened tubular bacterial sheaths, smooth and nanogranular non-crystalline extracellular polymeric substances (EPS), filamentous and spherical bacteriomorphs, as well as coccobacilli-like moulds. The biotic-mineralogical interface is characterised by microcrystalline rhombic dolomite, nano-sized pyrite spheroids and nano-sized flaky silicates in direct contact with biotic components. Interpreted as a mixed community of filamentous and coccoidal (cyano)bacteria, these microbes were important contributors to reef building. Preservation of microfossils was likely facilitated by synsedimentary silicification of EPS and bacterial sheaths. Microbial metabolic processes lowered kinetic barriers for authigenic precipitation of clay minerals on bacterial surfaces serving as nucleation sites. These synsedimentary clays strengthened initially soft microfabrics and potentially helped establish chemical conditions that promoted early diagenetic precipitation of protodolomite. The findings of this study show that carbonates may intricately preserve microfossils where associated with synsedimentary authigenic clays and microcrystalline dolomite.

We hypothesized that trapping and binding by microbial mats can promote the stabilization of sand-sized sediment and is therefore a process that should be considered as an important mode of biostabilization for sandy coastlines threatened by sea-level rise and increased storm intensity. To test this hypothesis, we designed a suite of in situ field incubation experiments to assess the amount of sediment microbial mats can trap if given a large sediment supply. These experiments, conducted on Little Ambergris Cay, Turks and Caicos Islands, focused on two of the most common morphologies of microbial mats (i.e., polygonal tufted mats and flat mats). We observed cyanobacterial filaments move around and on top of sand-sized grains within the first 24 h of each experiment, with increased movement related to environmental factors (duration of submergence, protection from tidal advection, and light availability). The results of our experiments show that polygonal tufted mats can stabilize twice the amount of sand-sized sediment than was naturally delivered over multi-month timescales, meaning these mats are sediment supply-limited and are capable of capturing more sediment. Furthermore, microbial mats have the capacity to trap and bind larger grains than seagrasses and mangroves.

In Proterozoic oceans, the precipitation of copper (Cu) with sulfide was hypothesized to limit the bioavailability of Cu. This limitation may have suppressed microbial reduction of nitrous oxide (N₂O), due to the Cu dependency of nitrous oxide reductase (Nos). It is thought that without this critical microbial sink, Proterozoic oceans were a significant net source of N₂O. Here, we revisit this paradigm in light of recently derived ~20-fold lower estimates for sulfide in Proterozoic seawater and an empirical evaluation of the potential for microbial N₂O reduction under sulfidic conditions. Leveraging publicly available environmental metatranscriptomes, we infer active N₂O reduction from the detection of <i>nosZ</i> transcripts in multiple marine and lacustrine systems in which sulfide and Cu concentrations are analogous to those of the Proterozoic. In controlled culture experiments, we demonstrate that the purple non-sulfur bacterium <i>Rhodopseudomonas palustris</i> can reduce N₂O at sulfide concentrations up to 50 μM, well above levels predicted for Proterozoic oceans. Based on trace metal speciation modeling, we suggest that Cu remains bioavailable under Proterozoic-like conditions as a dissolved CuHS⁰ complex. Collectively, these observations suggest microbial N₂O reduction occurs under euxinic conditions, implying that Proterozoic marine N₂O emissions were lower than previously proposed.

While <i>Shewanella</i> is widely recognized for its metal-reducing capabilities, recent studies have shown that certain terrestrial strains can also oxidize Mn²⁺ during aerobic respiration. Nevertheless, the Mn²⁺-oxidizing capacity of marine <i>Shewanella</i> strains, which are ubiquitous in oceanic settings, has remained largely unexplored, and the influence of environmental factors on this capacity has not been systematically evaluated. Here, we investigated the ability of the deep-sea bacterium <i>S. piezotolerans</i> WP3 to oxidize Mn²⁺ under aerobic conditions and examined the effects of temperature (4°C–20°C) and hydrostatic pressure (0.1–20 MPa). We found that <i>S. piezotolerans</i> WP3 efficiently oxidizes Mn²⁺ to Mn oxides, predominantly forming bixbyite-like minerals and amorphous mixed-valence nanoparticles. This oxidation process was not attributable to a Mn²⁺-specific enzyme but to bacterially generated reactive oxygen species (ROS), with superoxide (O₂^•-) playing the primary role. Both temperature and hydrostatic pressure significantly affected the final extent of Mn²⁺ oxidation by altering the production of O₂^•-. Transcriptomic analysis revealed that exposure to high hydrostatic pressure induced the upregulation of genes involved in antioxidative stress, which likely accounts for the enhanced ROS-mediated Mn²⁺ oxidation observed in cultures incubated at 20 MPa. Under alternating aerobic and anaerobic conditions, strain WP3 mediated successive Mn oxidation and reduction, ultimately forming rhodochrosite as a secondary mineral. These results suggest that <i>S. piezotolerans</i> WP3 has the potential to mediate Mn redox cycling in marine sediments, coupling ROS-dependent oxidation with anaerobic Mn reduction.</p>\u0000 </div>","PeriodicalId":173,"journal":{"name":"Geobiology","volume":"24 4","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148373265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The REY signatures of stromatolites are often similar to those of open ocean seawater. In restricted environments, however, REY fractionation can occur between waters and stromatolites, questioning their reliability to reconstruct microbial habitats through Earth's history. In this contribution, we determined the REY concentrations and partition coefficients (Kd_{(stromatolite-fluid)}) of sub-recent stromatolitic carbonates and ambient waters from the hypersaline Hamelin Pool in the Shark Bay lagoon, Australia. Shale-normalized REY patterns of stromatolite morphologies show (except colloform morphologies) a middle REY_SN enrichment relative to the light and heavy REY_SN. These signatures differ from those of seawater and ambient waters, suggesting that today's waters cannot be directly compared with stromatolitic carbonates from Shark Bay, which formed over thousands of years in a complex microbial mat system. Stromatolite morphologies such as colloform, smooth, or pustular structures formed in supratidal and intertidal environments exhibit the most variable Kd_{(stromatolite-fluid)} values for the REY. The most dominant process affecting REY geochemistry in the Shark Bay stromatolites is most likely organic matter degradation and subsequent REY release into porewaters from which the carbonates formed in a (semi)closed microbial mat system.
