The paper investigates the evolutionary distribution of nitrogen fixation in Thalassolituus by analyzing genome data, finding evidence of lateral gene transfer and recombination shaping nif loci.

This study tests an automated eDNA sampler in various aquatic environments, showing it can effectively profile eukaryotes, prokaryotes, and fish using ribosomal RNA genes and detect taxonomic groups and antimicrobial resistance genes.

The paper quantifies microbial degradation rates of organic carbon during a Phaeocystis bloom decline, showing that suspended carbon can be rapidly remineralized when blooms produce exopolymer-rich colonies.

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

The paper compares the spatio-temporal dynamics and composition of size-fractionated and unfractionated microbial communities in the Northwestern Atlantic, finding that de-fractionating samples before or after sequencing closely resembles unfractionated samples.

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.

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

The paper uses targeted metagenomics to analyze UCYN-A and its algal host in coastal Northwest Atlantic waters, revealing pangenomic diversity and co-occurring microbes.
