Marine biogeochemical nitrogen cycling through Earth's history
Earth's marine nitrogen cycle has co-evolved with life and redox conditions over geological
time. In this Review, we provide an account of nitrogen cycling in the world's oceans over the …

[HTML][HTML] The stability and collapse of marine ecosystems during the Permian-Triassic mass extinction
The history of Earth's biodiversity is punctuated episodically by mass extinctions. These are
characterized by major declines of taxon richness, but the accompanying ecological …

Global-ocean redox variation during the middle-late Permian through Early Triassic based on uranium isotope and Th/U trends of marine carbonates
Abstract Uranium isotopes (238U/235U) in carbonates, a proxy for global-ocean redox
conditions owing to their redox sensitivity and long residence time in seawater, exhibit …

Icehouse–greenhouse variations in marine denitrification
Long-term secular variation in the isotopic composition of seawater fixed nitrogen (N) is
poorly known. Here, we document variation in the N-isotopic composition of marine …

Redox conditions across the G–L boundary in South China: Evidence from pyrite morphology and sulfur isotopic compositions
Abstract The end-Guadalupian (middle Permian) mass extinction recorded the
disappearance of shelf faunas such as fusulinids, small foraminifers, brachiopods, rugose …

Early Triassic productivity crises delayed recovery from world's worst mass extinction
The recovery of life after the latest Permian extinction was protracted over Early Triassic
time. Detailed geochemistry of marine sections along northwest Pangea indicates that …

Progressive environmental deterioration in northwestern Pangea leading to the latest Permian extinction
Stratigraphic records from northwestern Pangea provide unique insight into global
processes that occurred during the latest Permian extinction (LPE). We examined a detailed …

Recovery from persistent nutrient-N limitation following the Permian–Triassic mass extinction
Global warming, widespread oceanic anoxia and stagnation, and large perturbations of the
global carbon cycle characterized the end-Permian to Middle Triassic interval. Nitrogen …
