In this study, 800-day microcosm experiments were performed with PE samples retrieved from an active landfill site with distinct landfill durations. Results demonstrated that anaerobic microbes slowly degrade PE while enhancing the release of secondary pollutants, such as nanoplastics (NPs) and phthalate esters (PAEs). Microbial colonization increased the surface roughness of PE samples and the abundance of oxygenated functional groups, driving oxidative chain scission, NP release (2.4-4.3 × 1011 particles mL-1 leachate), and PAE biodegradation. Logarithmic curves derived from an improved Polymer Aging Index revealed a midage acceleration window, with PE buried for 7 years being the most susceptible to microbial attack. PE-associated microbial communities were dominated by deterministic assembly processes, with functional taxa being the dominant drivers of PE aging, and PAE degraders exhibiting dual-threshold dynamics. Together, this study identifies a coupled oxidation-biodegradation-fragmentation feedbacks mechanism that governs the fate of PE in landfills, highlighting the dual microbial role in degrading PE and amplifying associated pollutant release. Keywords: assembly mechanism; degradation bacteria; landfill leachate; microorganisms; microplastic.

Ammonia-oxidizing archaea (AOA) exhibit significant diversification across various environmental conditions; however, their ecological dynamics, diversification, and associated evolutionary processes are still largely unexplored in coastal environments, which contain extensive ecosystem heterogeneity. Combining newly assembled metagenomic data from Chinese marginal seas (2059 km coverage) with global datasets (spanning over 16 000 km), these knowledge gaps were explored across a continental-scale latitudinal gradient. It revealed that coastal AOA genomic diversity is latitude-dependent, with predicted optimum growth temperatures and substrate metabolic pathways explaining the geographical distribution. The two dominant genus-level clades exhibited significantly distinct benthic-pelagic niches, associated with specific genes involved in nutrient uptake and stress resistance. Phylogenomic reconstructions suggest that AOA initially colonized the coastal ocean sediments around 718 million years ago (Mya), and subsequent purifying selection and low recombination facilitated the AOA niche expansion into marine coastal environments. By revealing the evolutionary trajectories of Nitrososphaeria and their differential colonization patterns, our findings offer a novel perspective on the mechanisms of AOA diversification in the coastal ocean. This work advances our understanding of microbial diversification and niche differentiation of AOA in coastal ecosystems as well as the evolutionary forces shaping their global biogeography. Keywords: Nitrososphaeria; ammonia-oxidizing archaea; coastal ocean; evolutionary adaptation; niche transition. © The Author(s) 2025.

While dermal denticle research is a growing field, there is currently no standardized vocabulary or framework to compare denticle morphology across research fields, siloing, and limiting denticle research efforts. Here, we present a morphological framework, which includes a character code that comprehensively captures denticle morphology from a wide diversity of denticle sampling types and imaging methods, and is backed by an easy-to-use google sheets-based coding tool and R package for replicating disparity analyses. The code is based on a wide-spread literature review of published denticle images, scanning electron microscope (SEMs), and computed tomography (CT) scans of extant shark denticles, and a review of tens of thousands of fossil denticles from pelagic ocean sediments dating back over 100 million years. The code's flexibility and replicability facilitate comparison across studies and independent research teams, and the addition of novel character categories. Denticle morphotypes are defined as denticles with unique combinations of character traits. This coding system facilitates morphologically backed disparity analyses of denticle morphological diversity, whether through deep time, across the body of a shark, or across a time-series of development, providing a more detailed, quantitative, and universal tool for analyzing denticle morphology across studies. Dentículos dérmicos - escamas microscópicas semelhantes a dentes - são uma característica diagnostica importante da pele dos elasmobrânquios e são de interesse para uma ampla variedade de áreas, incluindo paleontologia, biologia evolutiva, biologia do desenvolvimento, morfologia funcional e design bioinspirado. Embora a pesquisa sobre dentículos dérmicos seja uma área em crescimento, atualmente não existe um vocabulário ou estrutura padronizada para comparar a morfologia dos dentículos entre diferentes áreas de pesquisa, o que acaba isolando e limitando os esforços de pesquisa sobre dentículos. Aqui, apresentamos uma estrutura morfológica que inclui um código de caracteres que captura de maneira abrangente a morfologia dos dentículos a partir de uma grande diversidade de tipos de amostras de dentículos e métodos de imagem, e que é respaldada por uma ferramenta de codificação fácil de usar baseada no Google Sheets e por um pacote R para replicar análises de disparidade. O código é baseado em uma ampla revisão da literatura de imagens publicadas de dentículos, MEVs e tomografias computadorizadas (CT) de dentículos de tubarões viventes, além de uma revisão de dezenas de milhares de dentículos fósseis de sedimentos oceânicos pelágicos com mais de 100 milhões de anos. A flexibilidade e replicabilidade do código facilitam a comparação entre estudos e equipes de pesquisa independentes, além da adição de novas categorias de caracteres. Os morfotipos de dentículos são definidos como dentículos com combinações únicas de características. Este sistema de codificação facilita análises de disparidade com base morfológica sobre a diversidade morfológica dos dentículos, seja ao longo do tempo geológico, ao longo do corpo de um tubarão, ou ao longo de uma série temporal de desenvolvimento, oferecendo uma ferramenta mais detalhada, quantitativa e universal para analisar a morfologia dos dentículos em diferentes estudos.

Mientras la investigación de los dentículos dérmicos es un campo en expansión, actualmente no existe un vocabulario ni un marco estandarizado para comparar la morfología de los dentículos en diferentes campos de estudio, lo que aísla y limita los esfuerzos de investigación. Aquí se presenta un marco morfológico que incluye un código de caracteres que captura exhaustivamente la morfología de los dentículos dérmicos a partir de una amplia diversidad de tipos de muestreo y métodos de imagen. Este marco está respaldado por una herramienta de codificación fácil de usar basada en hojas de cálculo de Google y un paquete R para replicar análisis de disparidad. El código se basa en una extensa revisión bibliográfica de imágenes publicadas, microscopía electrónica de barrido (MEB) y tomografías computarizadas de dentículos de tiburón existentes, y en una revisión de decenas de miles de dentículos fósiles de sedimentos oceánicos pelágicos que datan de más de 100 millones de años. La flexibilidad y replicabilidad del código facilitan la comparación entre estudios y equipos de investigación independientes, así como la incorporación de nuevas categorías de caracteres.

By contrast, many biological and environmental settings-ranging from mucus in the body to ocean sediments and the soil beneath our feet-feature multicellular bacterial populations that are confined to tight spots where essential metabolic substrates (e.g., oxygen) are scarce. What influence does such confinement have on a bacterial population? Here, we address this question by studying suspensions of motile Escherichia coli confined to quasi two-dimensional (2D) droplets. We find that when the droplet size and cell concentration are both large enough, the initially uniform suspension spatially self-organizes into a concentrated, immotile inner "core" that coexists with a more dilute, highly motile surrounding "shell." By simultaneously measuring cell concentration, oxygen concentration, and motility-generated fluid flow, we show that this behavior arises from the interplay between oxygen transport through the droplet from its boundary, uptake by the cells, and corresponding changes in their motility in response to oxygen variations. Furthermore, we use biophysical theory and simulations to quantitatively describe this interplay. Our work thus sheds light on the rich collective behaviors that emerge for bacterial populations in confined environments, with implications for understanding ecological niches and engineering artificial systems.

They display an accordingly wide range of adaptive traits that enable their persistence, including, in some clades, a vast repertoire of biologically active small molecules. While humans have capitalized on this trove of useful natural products (also called secondary or specialized metabolites), the utility of these molecules for their producers has been challenging to directly assess. In this review, we consider adaptations that may have paved the way for the evolution of the expansive specialized metabolisms present in certain clades of Actinomycetota. We also consider the evolutionary pressures that may have driven diversification of these metabolisms and document how these organisms use these molecules in microbial interactions.

Until now, evidence supporting this hypothesis has come only from terrestrial sediment and ice-core records. Here we report the first discovery of similar impact-related proxies in ocean sediments from four marine cores in Baffin Bay that span the YDB layer at water depths of 0.5-2.4 km, minimizing the potential for modern contamination. Using scanning electron microscopy with energy-dispersive spectroscopy (SEM-EDS) and laser ablation ICP-MS, we detect synchronous abundance peaks of metallic debris geochemically consistent with cometary dust, co-occurring with iron- and silica-rich microspherules (4-163 μm) that are predominantly of terrestrial origin with minor ( PLoS One 1932-6203 1 South Carolina Institute for Archaeology and Anthropology, University of South Carolina, Columbia, South Carolina, United States of America.2 South Carolina Department of Natural Resources, Heritage Trust Program; Land, Water, and Conservation Division, Columbia, South Carolina, United States of America.3 Borok Geophysical Observatory of Schmidt Institute of Physics of the Earth of the Russian Academy of Sciences, Russian Federation.4 Center of Excellence in Remote Sensing Education and Research, Elizabeth City State University, Elizabeth City, North Carolina, United States of America.5 Comet Research Group, Prescott, Arizona, United States of America.6 Department of Earth, Environment and Planning, East Carolina University, Greenville, North Carolina, United States of America.7 Center for Environmental Nanoscience and Risk (CENR), Department of Environmental Health Sciences, Arnold School of Public Health, University of South Carolina, Columbia, United States of America.8 Department of Earth Science and Marine Science Institute, University of California Santa Barbara, Santa Barbara, California, United States of America.9 Armagh Observatory and Planetarium, College Hill, Armagh, Northern Ireland.10 School of Earth, Ocean and Environment, University of South Carolina, Columbia, South Carolina, United States of America.11 Department of Natural Sciences, Elizabeth City State University, Elizabeth City, North Carolina, United States of America.12 Department of Geoscience, University of Wisconsin - Madison, Madison, Wisconsin, United States of America.13 Geophysical Institute, University of Alaska Fairbanks, Fairbanks, Alaska, United States of America.14 Institute of Hydrogeology, Engineering Geology and Applied Geophysics, Charles University, Prague, Czechia.15 Center for Advanced Materials Characterization in Oregon, University of Oregon, Eugene, Oregon, United States of America.16 Electron Microscopy and Surface Analysis Lab, Nanofab, University of Utah, Salt Lake City, Utah, United States of America.17 College of Humanities, Arts and Social Sciences, Flinders University, South Australia.18 School of Earth, Ocean, and Environment, University of South Carolina, Columbia, South Carolina, United States of America.19 Planetary and Space Sciences, The Open University, Milton Keynes, United Kingdom.

Here, we collected 1,648 sediment samples at 6-11 km in the Mariana Trench, Yap Trench, and Philippine Basin for the Mariana Trench Environment and Ecology Research (MEER) project. Metagenomic and 16S rRNA gene amplicon sequencing generated the 92-Tbp MEER dataset, comprising 7,564 species (89.4% unreported), indicating high taxonomic novelty. Unlike in reported environments, neutral drift played a minimal role, while homogeneous selection (HoS, 50.5%) and dispersal limitation (DL, 43.8%) emerged as dominant ecological drivers. HoS favored streamlined genomes with key functions for hadal adaptation, e.g., aromatic compound utilization (oligotrophic adaptation) and antioxidation (high-pressure adaptation). Conversely, DL promoted versatile metabolism with larger genomes. These findings indicated that environmental factors drive the high taxonomic novelty in the hadal zone, advancing our understanding of the ecological mechanisms governing microbial ecosystems in such an extreme oceanic environment.

This study investigated the characteristics and distribution of MPs in sediments from the Pacific Ocean at depths of 4900-7016 m across three regions: Western Pacific (WP), Central Pacific (CP), and Eastern Pacific (EP). MPs were detected at all sampling sites, with the highest abundance in WP (111.3 ± 75.1 items/kg dw) and the lowest in CP (49.4 ± 18.7 items/kg dw). Site S9 was recorded as the peak abundance (270.1 ± 107.4 items/kg dw) in WP. MPs were predominantly fibers (94.8 %) in black, gray, and blue hues, mainly composed of polyester and rayon. Statistical analysis showed significant regional variations, reflecting anthropogenic impacts and complex deposition mechanisms.

Furthermore, many published budgets based on mass balance do not include all relevant carbon sources and sinks. Simulations of long-term decomposition of mangrove, saltmarsh (Spartina sp.), and eelgrass (Zostera sp.) litter using a 3-G exponential model indicate that current estimates of carbon sequestration based on the inventory and mass balance approaches are 3-18 times too high. Most published estimates of carbon sequestration in BCEs must therefore be considered overestimates. The climate mitigation potential of blue carbon in BCEs is also challenged by excess emissions of the GHG methane (CH4) and nitrous oxide (N2O) from biogenic structures in mangrove forests and saltmarsh sediments.
