Abstract Phytoplankton respond to physical and hydrographic forcing on time and space scales up to and including those relevant to climate change. Quantifying changes in phytoplankton communities over these scales is essential for predicting ocean fo

The ability of the ocean’s biota to sequester carbon is thought to be negatively affected by climate change. Here the authors use time-series data in the Sargasso Sea to show that biotic processes can buffer against these negative impacts.

Abstract Phytoplankton readily assimilate dissolved inorganic phosphorus (phosphate; Pi) into essential biomolecules, making it their preferred form of phosphorus (P). In low Pi marine environments, phytoplankton also utilize dissolved organic P (DOP

The Indian Ocean provides a unique environmental gradient to test underlying drivers of the elemental composition of particulate organic matter. Here the authors show that nutrient supply, over temperature and biodiversity changes, controls regional

The underlying regulatory mechanisms of phytoplankton assimilation and microbial oxidation of ammonium in the surface ocean are unclear. Here, using isotope labeling experiments, the authors show that ambient nitrate is a key variable bifurcating amm

Phytoplankton cellular elemental quotas are important for evaluating the coupling of nutrient cycles and assessing nutrient limitation in the ocean. While cell element quotas have been shown to vary in response to growth conditions (e.g., light, nutr

Current hypotheses suggest that cellular elemental stoichiometry of marine eukaryotic phytoplankton such as the ratios of cellular carbon:nitrogen:phosphorus (C:N:P) vary between phylogenetic groups. To investigate how phylogenetic structure, cell vo
