Single-cell transcriptomics highlights sexual cues among reproductive life stages of uncultivated Acantharia (Radiolaria)

This study uses single-cell transcriptomics to analyze reproductive life stages of Acantharia, identifying genetic evidence for a sexual cycle involving gamete-like swarmers.

Gelatinous matrix, an original strategy to cope with oligotrophy in Nassellaria (Radiolaria)

The paper identifies a gelatinous matrix in Nassellaria as an adaptation to oligotrophy, showing its evolutionary development and ecological significance in nutrient-depleted waters.

Seasonal dynamics of a glycan-degrading flavobacterial genus in a tidally-mixed coastal temperate habitat

The paper investigates seasonal dynamics of the glycan-degrading flavobacterial genus Zobellia in a coastal habitat, showing its abundance and activity vary with environmental factors and seasonal changes.

From genome wide SNPs to genomic islands of differentiation: the quest for species diagnostic markers in two scleractinian corals, Pocillopora and Porites

The paper develops a genotyping method called 'Divergent Fragment' to accurately assign coral samples to species within two genera, using sequencing of a diagnostic genomic fragment from metagenomic data.

Unveiling hidden eukaryotes: diversity of Endomyxa (Rhizaria) in coastal marine habitats

The paper investigates Endomyxa diversity in coastal marine habitats using targeted primers, revealing novel lineages and habitat-specific variations.

Insight into diatoms diversity at two European coastal sites (LTER-MC in the Mediterranean Sea and SOMLIT-Astan in the Western English Channel) using a DNA metabarcoding approach

The paper uses DNA metabarcoding to analyze diatom diversity at two coastal sites, finding shared ASVs and suggesting internal growth factors influence diversity patterns.

Open science resources from the Tara Pacific expedition across coral reef and surface ocean ecosystems

The paper describes the Tara Pacific expedition's sampling methodology and provides access to datasets from coral reef and surface ocean ecosystems.

Exploring the phycosphere of Emiliania huxleyi: from bloom dynamics to microbiome assembly experiments

This study investigates the microbiome dynamics of Emiliania huxleyi blooms by analyzing bacterial communities from bloom and non-bloom conditions and their interactions over time.

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.

Genomic evidence for global ocean plankton biogeography shaped by large-scale current systems

The paper analyzes plankton genomic distribution across oceans to show how large-scale currents shape biogeography, revealing size-dependent patterns and basin-scale transport effects.

Plankton Planet: 'seatizen' oceanography to assess open ocean life at the planetary scale

Plankton Planet uses citizen science to collect global plankton biodiversity data via DNA barcodes, achieving comparable quality to Tara Oceans with a scalable, open-access approach.

Soil Protists in Three Neotropical Rainforests are Hyperdiverse and Dominated by Parasites

The paper investigates protist diversity in Neotropical rainforest soils, finding them hyperdiverse and dominated by parasitic Apicomplexa, which may influence animal diversity.
