Patterns of Aminicenantes relative abundance in datasets classified by prevalent environmental conditions1.

1A detailed description of every dataset is provided as supplementary material (Supplementary Table S1 in File S1).2Average abundance values in datasets where Aminicenantes sequences were identified.3Temperature classifications: Low: Arctic, Antarctic, subarctic, and permafrost marine and terrestrial conducive to the growth of psychrophilic microorganisms; temperate: Habitats in temperate ecosystems e.g. lakes, soils in continental settings; Medium: Habitats with temperatures around 37°C e.g. rumen; Elevated: habitats with temperatures conducive to the growth of thermophiles (50–80°C) e.g. Alberta oil sands tailings pond; Extremely elevated: habitats conducive to the growth of hyperthermophiles (>80°C degrees) e.g. Hydrothermal vents.4Salinity classifications: Non-saline: Environments with 15% salinity.
