The ecological physiology of Earth's second oxygen revolution
Living animals display a variety of morphological, physiological, and biochemical characters
that enable them to live in low-oxygen environments. These features and the organisms that …

A basin redox transect at the dawn of animal life
Multiple eukaryotic clades make their first appearance in the fossil record between~ 810 and
715Ma. Molecular clock studies suggest that the origin of animal multicellularity may have …

Faunal responses to oxygen gradients on the Pakistan margin: a comparison of foraminiferans, macrofauna and megafauna
The Pakistan Margin is characterised by a strong mid-water oxygen minimum zone (OMZ)
that intercepts the seabed at bathyal depths (150–1300m). We investigated whether faunal …

Selenium isotopes record extensive marine suboxia during the Great Oxidation Event
It has been proposed that an “oxygen overshoot” occurred during the early Paleoproterozoic

Dissolved oxygen and suspended particles regulate the benthic flux of iron from continental margins
We present ex situ sediment incubation results from the California and Oregon shelves and
compare the calculated benthic flux of dissolved Fe with those from in situ incubations and …
