Nitrogen fixation in mesoscale eddies of the North Pacific Subtropical Gyre: patterns and mechanisms

The paper investigates elevated nitrogen fixation rates in mesoscale eddies of the North Pacific Subtropical Gyre, finding that anticyclones support higher diazotroph abundances due to phosphate limitation relief, while physical dynamics influence other taxa.

Siderophore production and utilization by microbes in the North Pacific Ocean

The paper measures dissolved siderophore concentrations and types in the North Pacific Ocean, linking their distribution to microbial activity and environmental factors.

A flexible Bayesian approach to estimating size-structured matrix population models

This paper introduces a Bayesian framework to improve the estimation of size-structured matrix population models for microbial dynamics, demonstrating better performance and biological interpretability.

A Kernel-Based Change Detection Method to Map Shifts in Phytoplankton Communities Measured by Flow Cytometry

This paper introduces CytoSegmenter, a kernel-based method for segmenting flow cytometry point cloud data to detect shifts in phytoplankton communities, showing these shifts correlate with ocean temperature and salinity changes.

Disentangling top-down drivers of mortality underlying diel population dynamics of Prochlorococcus in the North Pacific Subtropical Gyre

The paper develops multitrophic models to investigate top-down and bottom-up drivers of Prochlorococcus population dynamics in the North Pacific Subtropical Gyre, finding grazers are the primary top-down factor despite high viral densities.

Marine community metabolomes carry fingerprints of phytoplankton community composition

The paper shows that marine community metabolomes reflect phytoplankton community composition and highlights understudied compounds that represent significant pools of labile carbon.

Diel Oscillations of Particulate Metabolites Reflect Synchronized Microbial Activity in the North Pacific Subtropical Gyre

The paper measures diel oscillations of particulate metabolites and transcripts in the North Pacific Subtropical Gyre, showing 24-hour periodicity and microbial strategies for energy and redox management.
