Abstract: A marked 120 My gap in the fossil record of vampire squids separates the only extant species (Vampyroteuthis infernalis) from its Early Cretaceous, morphologically-similar ancestors. While the extant species possesses unique physiological adaptations to bathyal environments… read more here.

DOI: 10.1071/mf20074
Abstract: The marine N cycle is driven mainly by microorganisms whose distribution can be shaped by mesoscale eddies. Recently, eddies containing oxygen minimum zones (OMZs) have been recognised as N-loss hotspots, complicating even more the calculations… read more here.

DOI: 10.1111/mec.14465
Abstract: Symbioses between anaerobic or microaerophilic protists and prokaryotes are common in anoxic and oxygen‐depleted habitats ranging from marine sediments to gastrointestinal tracts. Nevertheless, little is known about the mechanisms of metabolic interaction between partners. In… read more here.

DOI: 10.3389/fmicb.2021.764605
Abstract: Oxygen-depleted water columns (ODWCs) host a diverse community of eukaryotic protists that change dramatically in composition over the oxic-anoxic gradient. In the permanently anoxic Cariaco Basin, peaks in eukaryotic diversity occurred in layers where dark… read more here.
