Particle-based representation of phytoplankton modulates emergent coexistence and biogeography in a model ocean

This study compares Eulerian and Lagrangian models of phytoplankton communities in an ocean circulation model, showing that particle-based methods produce distinct biogeography and diversity patterns.

Global population structure of a unicellular marine predator

This study examines population diversity and structure of four MAST-4 species using metagenomics and single-cell genomics, revealing temperature and salinity as key drivers of population divergence.

Biological and genomic resources for the cosmopolitan phytoplankton Bathycoccus: Insights into genetic diversity and function of outlier chromosomes

The paper presents 28 high-quality genome sequences of Bathycoccus species, revealing structural variations and haplotype diversity, and provides genomic resources to study eukaryotic phytoplankton diversity and evolution.

Genomics-based quantitative biogeography of marine plankton

This study generates absolute estimates of plankton cell concentrations and carbon biomass using environmental genomic data, revealing ecological associations and quantitative biogeographies of photosynthetic lineages.

Patterns and drivers of diatom diversity and abundance in the global ocean

This study analyzes diatom diversity and abundance in the global ocean using Tara Oceans data, identifying key environmental drivers and community patterns.

Deviation from Power-Law Distribution when Scaling the Distribution of Marine Plankton Folds from Genomes to Communities

The paper shows that the distribution of protein folds in marine plankton communities deviates from a power law to a Type II Pareto distribution when scaling from individual genomes to communities.

Changes in gene expression in eukaryotic phytoplankton at the Atlantic-Arctic polar front

The paper analyzes metatranscriptomes across a North Atlantic-Arctic gradient, finding differential and convergent gene expression changes in eukaryotic phytoplankton at the polar front.

Genomic adaptation of the picoeukaryote Pelagomonas calceolata to temperate iron-poor oceans revealed by a chromosome-scale genome sequence.

The paper reports the chromosome-scale genome of Pelagomonas calceolata, revealing adaptations to iron-poor environments and its potential expansion under climate change.

Equatorial to Polar genomic variability of the microalgae Bathycoccus prasinos

The paper studies genomic variability in Bathycoccus prasinos across different oceanic temperatures, finding temperature-associated variant frequency changes and minimal mutational strategies for thermal adaptation.
