This study investigates basin-scale dynamics and genomic uniqueness of marine nitrifiers in the Baltic Sea, revealing seasonal patterns, environmental interactions, and niche differentiation.

The paper shows that sea urchin eggs incorporate plastid components, which enhance offspring developmental fitness and survival by influencing phytohormone regulation and lipid use.

The paper introduces the JEDI marker as a universal biodiversity measure, demonstrating its applicability across ecological scales and providing an automated bioinformatic workflow for standardized analysis.

The paper studies Arctic Ocean virus communities over four years, revealing seasonality, bipolar distribution, and interactions with prokaryotes.

The paper validates HiMEx, a microvolume DNA extraction method, showing it captures comparable microbial community data and more viral genomes than conventional methods at lower cost.

The paper investigates how an invasive seaweed host influences its microbial biofilm compared to native hosts, finding it exerts greater influence and promiscuity in microbial associations.

The paper uses metatranscriptomics to study viral infections in coastal California, showing viruses contribute significantly to photosynthesis through psbA expression.
