    Drivers of methane-cycling archaeal abundances, community structure, and catabolic pathways in continental margin sediments by Longhui Deng, Longhui Deng, Damian Bölsterli, Clemens Glombitza, Bo Barker Jørgensen, Hans Røy, Mark Alexander Lever, Mark Alexander Lever

    Published 2025-02-01
    “…While numerous studies have investigated communities of methane-cycling archaea in hydrocarbon seeps and sulfate–methane transition zones, less is known about how these archaea change from the seafloor downward throughout diffusion-dominated marine sediments. Focusing on four continental margin sites of the North Sea-Baltic Sea transition, we here investigate the in situ drivers of methane-cycling archaeal community structure and metabolism based on geochemical and stable carbon-isotopic gradients, functional gene (mcrA) copy numbers and phylogenetic compositions, and thermodynamic calculations. …”
