Ubiquity of inverted 'gelatinous' ecosystem pyramids in the global ocean

The paper quantifies plankton community structure globally, revealing inverted biomass pyramids dominated by gelatinous organisms and predicting future shifts in oceanic carbon cycles.

Vertical distribution and light energy capture by AAP bacteria along contrasted areas of productivity in the Atlantic Ocean

The paper examines the vertical distribution and light energy capture of AAP bacteria in the Atlantic Ocean, finding strong correlations with chlorophyll a and picophytoplankton abundance.

Manipulation in grazing, viral pressure and resource availability leads to success in the isolation of abundant marine bacteria

This study isolates marine bacteria from manipulated seawater samples and finds that reduced grazing, viral pressure, and increased nutrients enhance culturability, challenging the 1% culturability paradigm.

Marine picoplankton metagenomes from eleven vertical profiles obtained by the Malaspina Expedition in the tropical and subtropical oceans

The paper presents a dataset of marine picoplankton metagenomes from 11 vertical profiles, providing insights into functional and taxonomic connectivity between photic and bathypelagic zones.

Global biogeography of the smallest plankton across ocean depths

This study investigates how ecological mechanisms shape picoplankton communities across different ocean depths, finding that selection decreases and dispersal limitation increases with depth.

Abundant deep ocean heterotrophic bacteria are culturable

The paper shows that a significant portion of deep ocean heterotrophic bacteria can be cultured, with isolates matching abundant 16S ASVs in bathypelagic samples.

Water mass age structures the auxiliary metabolic gene content of free-living and particle-attached deep ocean viral communities

The paper analyzes deep ocean viral communities to show that water mass age influences their taxonomic composition and auxiliary metabolic gene content.

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.

A robust approach to estimate relative phytoplankton cell abundance from metagenomes

This paper introduces a PCR-free method using the psbO gene to estimate phytoplankton abundance from metagenomes, showing better correlation with flow cytometry and microscopy than rRNA genes.

The quality of dissolved organic matter shapes the biogeography of the active bathypelagic microbiome

This study investigates the role of dissolved organic matter quality in shaping the active bathypelagic microbiome, finding that free-living prokaryotes contribute significantly in DOM-depleted regions.

Long-term patterns of an interconnected core marine microbiota

The paper identifies a dynamic core marine microbiota in a Mediterranean coastal observatory over 10 years, showing seasonal variations and interactions among core taxa.

Seasonal niche differentiation between evolutionary closely related marine bacteria

This study examines niche differentiation among closely related marine bacteria, finding that niche similarity decreases with genetic divergence and that niche partitioning occurs within genera but not at broader taxonomic levels.

Rapid Evolution of Plastic-degrading Enzymes Prevalent in the Global Ocean

The paper identifies oceanic PETase variants in marine metagenomes, showing their prevalence and potential role in plastic degradation.

Diversity patterns of marine heterotrophic culturable bacteria along vertical and latitudinal gradients

The paper isolates and analyzes marine heterotrophic bacteria from various oceanic regions, revealing distribution patterns and high similarity between photic and aphotic isolates.

Metabolic Architecture of the Deep Ocean Microbiome

The paper analyzes deep ocean microbial metagenomes to reveal functional diversity and metabolic strategies in the dark ocean.

Marked changes in diversity and relative activity of picoeukaryotes with depth in the global ocean

The paper examines picoeukaryotic communities across ocean depth layers, finding stratification and distinct activity patterns, with highest activity in the mesopelagic layer.

Long-term seasonality of marine photoheterotrophic bacteria reveals low cohesiveness within the different phylogroups

The paper examines long-term seasonal dynamics of marine photoheterotrophic bacteria over a decade, revealing low cohesiveness within phylogroups and distinct niche partitioning.
