Microbe-Mediated Degradation of Polyethylene and Release of Associated Pollutants under Simulated Dark Environments [0.03%]
模拟暗环境中微生物介导的聚乙烯降解及关联污染物的释放
Changfu Yang,Qiujie Huang,Hui Wang et al.
Changfu Yang et al.
Polyethylene (PE) dominates global packaging waste, yet its fate remains poorly understood in dark, anoxic environments such as ocean sediments and landfills, which represent important reservoirs for discarded plastics.
Purifying selection and low recombination facilitated sequential colonization of benthic and pelagic coastal ocean by ammonia-oxidizing archaea [0.03%]
纯化选择和低重组使氨氧化古菌依次定植滨海海底和水柱环境
Gaoyang Ren,Cécile Gubry-Rangin,Wenhao Wang et al.
Gaoyang Ren et al.
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.
Quantifying the Denticle Multiverse: A Standardized Coding System to Capture Three Dimensional Morphological Variations for Quantitative Evolutionary and Ecological Studies of Elasmobranch Denticles [0.03%]
量化棘鳞多元宇宙：一个标准化编码系统，用于捕捉形态学变化的三维变异，以进行定量进化和生态研究的软骨鱼类棘鳞分类体系
L D Rubin,G J Fraser,M K Gabler-Smith et al.
L D Rubin et al.
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.

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.
Why Do Filamentous Actinomycetota Produce Such a Vast Array of Specialized Metabolites? [0.03%]
丝状放线菌为什么会产生如此众多的专业代谢产物？
Luis M Cantu Morin,Kilian Dekoninck,Varun Sridhar et al.
Luis M Cantu Morin et al.
Bacteria of the phylum Actinomycetota are extremely diverse: They inhabit niches ranging from soils and ocean sediments to the normal human microbiota, and they cause tuberculosis, one of the most prevalent chronic bacterial infections.
A 12,800-year-old layer with cometary dust, microspherules, and platinum anomaly recorded in multiple cores from Baffin Bay [0.03%]
记录在巴芬湾多个岩芯中的含有微球体和铂异常的1.28万年前彗星尘层
Christopher R Moore,Vladimir A Tselmovich,Malcolm A LeCompte et al.
Christopher R Moore et al.
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.
Microbial ecosystems and ecological driving forces in the deepest ocean sediments [0.03%]
最深海洋沉积物中的微生物生态系统及其生态驱动因素
Xiang Xiao,Weishu Zhao,Zewei Song et al.
Xiang Xiao et al.
Systematic exploration of the hadal zone, Earth's deepest oceanic realm, has historically faced technical limitations. Here, we collected 1,648 sediment samples at 6-11 km in the Mariana Trench, Yap Trench, and Philippine Basin for the Mari...
Unveiling the deep-sea microplastic Odyssey: Characteristics, distribution, and ecological implications in Pacific Ocean sediments [0.03%]
揭开深海微塑料奥德赛：太平洋洋底的特性、分布及生态影响
Hua Deng,Yutao Fu,Lei Su et al.
Hua Deng et al.
Microplastics (MPs) in deep-sea environments are a growing concern due to their potential ecological risks and the deep sea's role in global biogeochemical cycles. This study investigated the characteristics and distribution of MPs in sedim...
Niche Partitioning and Intraspecific Variation of Thaumarchaeota in Deep Ocean Sediments [0.03%]
深海沉积物中古菌的生态分化及种内差异性研究
Ronghua Liu,Xinxin He,Gaoyang Ren et al.
Ronghua Liu et al.
Deep-sea sediments contain a large number of Thaumarchaeota that are phylogenetically distinct from their pelagic counterparts. However, their ecology and evolutionary adaptations are not well understood. Metagenomic analyses were conducted...
Predicting Climate Mitigation Through Carbon Burial in Blue Carbon Ecosystems-Challenges and Pitfalls [0.03%]
预测通过蓝色碳汇生态系统中的碳封存来进行气候缓解-挑战与困境
Erik Kristensen,Mogens R Flindt,Cintia O Quintana
