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.

Genome-scale community modelling reveals conserved metabolic cross-feedings in epipelagic bacterioplankton communities

The paper uses integrated ecological and metabolic modelling to identify conserved metabolic cross-feedings in epipelagic bacterioplankton communities.

Loss of the benthic life stage in Medusozoa and colonization of the open ocean

The paper shows that holoplanktonic medusozoans are more globally distributed and abundant than meroplanktonic ones, suggesting the loss of the benthic stage enabled open ocean colonization.

Genomic adaptation of giant viruses in polar oceans

This study investigates how giant viruses adapt to polar ocean environments by analyzing their biogeography and functional genes, finding that their adaptation is independent of host adaptation.

Global observation of plankton communities from space

The paper uses satellite data and machine learning to predict global plankton community distributions with 67% accuracy, outperforming temperature and chlorophyll a alone.

Non-cyanobacterial diazotrophs from the Rhizobiales order support marine microalgae in nitrogen-depleted environments

The paper identifies non-cyanobacterial diazotrophs from the Rhizobiales order associated with marine microalgae and demonstrates their nitrogen-fixing ability in nitrogen-depleted environments.

Seasonal temporal dynamics of marine protists communities in tidally mixed coastal waters

The paper analyzes seasonal changes in marine protist communities using long-term data from microscopy and metabarcoding, revealing seasonal patterns and environmental influences.

Disentangling temporal associations in marine microbial networks

The paper investigates temporal dynamics of microbial associations in a Mediterranean Sea time series using a temporal network approach, finding annual cycles and seasonal variability in microbial interactions.

Disentangling marine microbial networks across space

This study examines how microbial associations change across different ocean depths and regions, finding that most surface associations disappear with depth and that associations are highly variable across space.

Ocean-wide comparisons of mesopelagic planktonic community structures

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

Environmental vulnerability of the global ocean plankton community interactome

The paper assesses the vulnerability of the global ocean plankton community interactome to environmental change using niche modeling and Tara Oceans data.

Quantitative assessment of NCLDV-host interactions predicted by co-occurrence analyses

This study uses co-occurrence analyses to predict NCLDV hosts from Tara Oceans data, showing improved performance with a phylogeny-informed method.

Eukaryotic virus composition can predict the efficiency of carbon export in the global ocean

This study links viral community composition to carbon export efficiency in the global ocean, finding that viral marker genes explain 67% of variation in CEE.

Ecogenomics of key prokaryotes in the Arctic Ocean

The paper reconstructs metagenomic bins from Arctic Ocean samples to characterize microbial communities and their metabolic capabilities, identifying novel species and active MAGs that may serve as climate change sentinels.

Polar opposites; bacterioplankton susceptibility and mycoplankton resistance to ocean acidification

This study examines how ocean acidification affects bacterioplankton and mycoplankton diversity and function in the Southern Ocean, finding divergent responses with potential ecological consequences.
