Phosphorus (P) availability is usually low in soils around the globe. Most soils have a
deficiency of available P; if they are not fertilized, they will not be able to satisfy the P …

The long history of life on Earth has unfolded as a cause-and-effect relationship with the
evolving amount of oxygen (O2) in the oceans and atmosphere. Oxygen deficiency …

Geological evidence indicates that grounded ice sheets reached sea level at all latitudes
during two long-lived Cryogenian (58 and≥ 5 My) glaciations. Combined uranium-lead and …

The rise of atmospheric oxygen fundamentally changed the chemistry of surficial
environments and the nature of Earth's habitability. Early atmospheric oxygenation occurred …

The macronutrient phosphorus is thought to limit primary productivity in the oceans on
geological timescales. Although there has been a sustained effort to reconstruct the …

The transition from dominant bacterial to eukaryotic marine primary productivity was one of
the most profound ecological revolutions in the Earth's history, reorganizing the distribution …

The availability of carbon from rising atmospheric carbon dioxide levels and of nitrogen from
various human-induced inputs to ecosystems is continuously increasing; however, these …

Phosphorus (P) is critical to modern biochemical functions and can control ecosystem
growth. It was presumably important as a reagent in prebiotic chemistry. However, on the …

The rapid increase of carbon dioxide concentration in Earth's modern atmosphere is a
matter of major concern. But for the atmosphere of roughly two-and-half billion years ago …

Phosphorus is a limiting nutrient that is thought to control oceanic oxygen levels to a large
extent,–. A possible increase in marine phosphorus concentrations during the Ediacaran …
