The paper quantifies B-vitamins and microbial communities in a temperate estuary, finding key B-vitamins influence plankton composition and revealing spatial and temporal dynamics.

This study examines how glacier-induced upwelling affects microbial communities in Arctic marine systems, finding that it alters nutrient availability and microbial composition.

This study isolates and characterizes Thalassolituus haligoni, a non-cyanobacterial diazotroph, revealing its N2 fixation capabilities and growth preferences.

The paper examines elemental allocation in Southern Ocean microbial proteins and metabolic processes, showing how iron scarcity affects metal distribution and challenges assumptions about nutrient stoichiometry.

This study measures b-vitamins and cobalamin in the Northwest Atlantic over 5 years, showing seasonal differences in their concentrations and their impact on phytoplankton growth.

The paper quantifies the role of superoxide dismutases in manganese stoichiometry of Southern Ocean diatoms and identifies environmental controls on these enzymes.

This paper shows a diatom produces the cobalamin lower ligand, α-ribazole, under cobalamin-deplete conditions, suggesting eukaryotic contributions to cobalamin remodeling in marine ecosystems.

This study measures pseudocobalamin and methionine synthase in Synechococcus cultures and communities, showing consistent pseudocobalamin quotas in the Northwest Atlantic Ocean.
