The study investigates the metabolic pathways of a toxic Planktothrix rubescens bloom using metagenomics and metabolomics, revealing the role of the ornithine-arginine cycle in its ecological success.

The paper investigates how declining ice cover in Lake Erie affects diatom blooms by analyzing physiochemical and metatranscriptomic data, finding light limitation and adaptive gene expression changes.

This study compares microcystin production in a toxigenic and non-toxigenic strain of M. aeruginosa under cold temperatures, showing increased microcystin quota and physiological changes in the wildtype.

The paper develops a molecular toolset using DNA barcoding and NGS to rapidly assess phytoplankton communities, focusing on harmful algal blooms and toxin-producing cyanobacteria.
