The paper measures sinking velocities of marine aggregates using PIV and shows small aggregates contribute 40-70% to carbon flux due to higher size-specific settling velocities.

This study shows that phytoplankton actively regulate local pH to create distinct gravitactic sub-populations, leading to irregular diel vertical migration patterns.

This study uses phylogenomic data from new and existing sequences to show multiple independent transitions between parasitism and saprotrophy in chytrids, with the last common ancestor being a phytoplankton parasite.

The paper investigates how fungal parasites and zooplankton grazing interact to influence competition between edible and inedible phytoplankton, finding synergistic effects under different nutrient conditions.

This study identifies perchlorate-specific proteomic stress responses in Debaryomyces hansenii, revealing mechanisms that may enable microbial survival in Martian brines.

The paper assesses biodiversity homogenization in kettle holes across different land-use types using eDNA sequencing and finds that agricultural intensification and nutrient enrichment lead to reduced biodiversity differences.

The paper quantifies Prochlorococcus carbon acquisition, showing mixotrophy supports its ecological success in oceanic environments.

The paper shows that phytoplankton exudates supply both carbon and nutrients (N, P) to specific bacteria in coastal and open-ocean ecosystems of the Eastern Mediterranean.

The paper shows that extreme rain events cause cyclic succession in microbial and plankton communities of a forest pond, with recovery occurring through four distinct phases.

The paper shows Achromatium, a polyploid bacterium, has a globally identical functional inventory across diverse ecosystems, adapting through gene expression rather than genetic change.

The paper identifies bacterial traits for microbial interactions using a whole-genome approach across 473 marine bacterial genomes, revealing functional clusters and interaction patterns.

The paper identifies urban-specific bacteria in freshwater ecosystems, including potential pathogens, showing urbanization alters microbial communities and creates health risks.

This study shows Prochlorococcus survive nutrient starvation through interactions with heterotrophic bacteria, not by forming chlorotic resting stages.

This study identifies four Saprolegniales species in Anzali lagoon, Iran, and evaluates their enzymatic activities, highlighting their ecological roles in freshwater ecosystems.

The paper examines how land use and water chemistry influence microbiomes in a connected lakes system, finding that land use within drainage basins affects water quality and microbial structure, while direct land use around lakes has minimal impact.

This study shows Cyanobacteria produce methane in both oxygenated and anoxic conditions, challenging the view that methanogenesis is exclusive to Archaea and linking it to climate change and Earth's methane history.

This study examines fungal communities in groundwater near two lakes in NE Germany, finding high diversity and functional roles in degrading organic matter.

This study shows that zooplankton carcasses rapidly decompose in freshwater, altering bacterial communities but not affecting humic matter degradation.

The paper highlights the importance of randomization and balancing in molecular ecology experiments to avoid biased results from unaccounted laboratory procedures.

The paper investigates metabolic interactions among free-living freshwater bacteria and finds they form loose, unspecific cooperative networks rather than specific dependencies.

The paper uses DNA-metabarcoding on unfractionated water samples to study plankton dynamics, revealing a bacterial bloom that traditional methods missed.
