Defining metabolic niches for marine microbial heterotrophs

Understanding carbon cycling requires simplifying bacterial diversity into functional groups defined by genetic signatures.

Characterization of phytoplankton-excreted metabolites mediating carbon flux through the surface...

The marine labile dissolved organic carbon (DOC) pool is a dynamic reservoir of thousands of molecules that cycles approximately one-quarter of Ear...

Sub-daily virus sampling at the Bermuda Atlantic Time Series reveals diel and depth-structured...

Viruses are often studied in disease settings, but in the ocean they outnumber cells and shape ecosystems, yet their dynamics remain poorly understood. In this study, high-resolution sampling of...

Seasonal patterns of DOM molecules are linked to microbial functions in the oligotrophic ocean |...

Marine dissolved organic matter (DOM) is a major carbon reservoir that acts as a critical control on the Earth’s climate. DOM dynamics are largely regulated by a complex web of chemical-microbial...

Wave‐driven transport controls bacterioplankton community differentiation among coral reef habitats

The existence of highly productive coral reefs within oligotrophic gyres is in part due to intensive recycling of macronutrients and organic matter by microbes. Therefore, characterizing reef...

Columbian mammoth mitogenomes from Mexico uncover the species’ complex evolutionary history

Paleogenomic studies suggest that Mammuthus columbi derives from an ancient hybridization between Mammuthus primigenius and Mammuthus trogontherii. Although its habitat spanned from North to Central...

Functional genomic signatures predict microbial culturability across the tree of life

Most microbial taxa on Earth remain uncultivated, limiting our ability to study their physiology, ecology, and roles in environmental processes. Although metagenome-assembled genomes (MAGs) have...

The MicrobeAtlas database: Global trends and insights into Earth’s microbial ecosystems

Environmental DNA sequencing has revolutionized our understanding of microbial diversity and ecology. Microbiomes have now been sequenced across the entire planet—from the deep subsurface to the...

An ecological framework for microbial metabolites in the ocean ecosystem

The ocean microbe-metabolite network involves thousands of individual metabolites that encompass a breadth of chemical diversity and biological functions. These microbial metabolites mediate biogeo...

Giant viruses specific to deep oceans show persistent presence and activity

Giant viruses (GVs) of the phyla Nucleocytoviricota and Mirusviricota are large double-stranded DNA viruses that infect diverse eukaryotic hosts and impact biogeochemical cycles. Their diversity and...
