The impact of temperature on marine phytoplankton resource allocation and metabolism
The effect of temperature on marine phytoplankton growth strategies, metabolism and composition is studied using a range of techniques. This approach indicates that temperature plays a previouslyExpand

Earliest land plants created modern levels of atmospheric oxygen
Significance The rise of atmospheric oxygen over Earth’s history has received much recent interdisciplinary attention. However, the puzzle of when and how atmospheric oxygen reached modern levelsExpand

Ocean acidification and the Permo-Triassic mass extinction
Ocean acidification and mass extinction The largest mass extinction in Earth's history occurred at the Permian-Triassic boundary 252 million years ago. Several ideas have been proposed for whatExpand

Biogeochemical Transformations in the History of the Ocean.
The ocean has undergone several profound biogeochemical transformations in its 4-billion-year history, and these were an integral part of the coevolution of life and the planet. This review focusesExpand

Multiple environmental controls on phytoplankton growth strategies determine adaptive responses of the N : P ratio.
The controls on the 'Redfield' N : P stoichiometry of marine phytoplankton and hence the N : P ratio of the deep ocean remain incompletely understood. Here, we use a model for phytoplanktonExpand

Environmental selection and resource allocation determine spatial patterns in picophytoplankton cell size
Here we describe a new trait-based model for cellular resource allocation that we use to investigate the relative importance of different drivers for small cell size in phytoplankton. Using theExpand

COPSE reloaded: An improved model of biogeochemical cycling over Phanerozoic time
Abstract The ‘COPSE’ (Carbon, Oxygen, Phosphorus, Sulphur and Evolution) biogeochemical model predicts the coupled histories and controls on atmospheric O2, CO2 and ocean composition over PhanerozoicExpand

The effect of widespread early aerobic marine ecosystems on methane cycling and the Great Oxidation
The balance of evidence suggests that oxygenic photosynthesis had evolved by 3.0–2.7 Ga, several hundred million years prior to the Great Oxidation ≈2.4 Ga. Previous work has shown that if oxygenicExpand

Changing tectonic controls on the long‐term carbon cycle from Mesozoic to present
Tectonic drivers of degassing and weathering processes are key long-term controls on atmospheric CO2. However, there is considerable debate over the changing relative importance of different carbonExpand

Atmospheric oxygen regulation at low Proterozoic levels by incomplete oxidative weathering of sedimentary organic carbon
It is unclear why atmospheric oxygen remained trapped at low levels for more than 1.5 billion years following the Paleoproterozoic Great Oxidation Event. Here, we use models for erosion, weatheringExpand
