    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
    “…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. We observe major changes in community structure that largely follow vertical gradients in sulfate concentrations and lateral gradients in organic carbon reactivity and content. …”
