The paper identifies horizontal gene transfer as a driver of convergent evolution in Arctic microalgae, highlighting ice-binding domain gene transfers between distantly related species.

This paper introduces a metabolic niche concept that integrates genome-scale metabolic models to improve ecological niche theory by capturing functional gene presence and metabolic capabilities beyond simple presence-absence.

This paper introduces a PCR-free method using the psbO gene to estimate phytoplankton abundance from metagenomes, showing better correlation with flow cytometry and microscopy than rRNA genes.

The paper identifies heterotrophic bacterial diazotrophs as more abundant than cyanobacterial diazotrophs in ocean metagenomes, expanding the known diversity of marine nitrogen fixers.

This study compares mesopelagic planktonic community structures across different oxygen conditions and identifies environmental drivers and community modules.

The paper combines imaging and molecular data to analyze the global distribution of marine nitrogen-fixers, revealing size-related patterns and new high-density regions.
