Differences in density: taxonomic but not functional diversity in seaweed microbiomes affected by an earthquake

The paper examines how earthquake-induced changes in kelp density affect seaweed microbiome diversity, finding taxonomic but not functional differences.

Salp blooms increase carbon export 5-fold in the Southern Ocean

This study shows salp blooms increase carbon export by 5-fold in the Southern Ocean, enhancing BCP efficiency to 28%.

Molecular hydrogen is an overlooked energy source for marine bacteria

This study shows marine bacteria consume molecular hydrogen as an energy source, with H2 oxidation more active in subantarctic waters and supported by genomic and experimental evidence.

High viral abundance and low diversity are associated with increased CRISPR-Cas prevalence across microbial ecosystems

The paper examines the relationship between viral abundance and diversity and CRISPR-Cas prevalence across microbial ecosystems using metagenomic data.

Soil Chemistry and Microbiome Determine N2O Emission Potential in Soils

The paper assesses the impact of soil microbiome and chemistry on N2O emission potential using an anoxic assay system, finding that chemical factors have a greater influence than microbiome composition.

Predation impacts late but not early community assembly in model marine biofilms.

This study examines how predation affects microbial community assembly in marine biofilms over time, finding that top-down selection impacts late-stage communities more than early ones.

Soil N2O emission potential falls along a denitrification phenotype gradient linked to differences in microbiome, rainfall and carbon availability

The paper investigates how soil N2O emission potential relates to microbiome, rainfall, and carbon availability, identifying sequential vs. concurrent denitrification phenotypes that influence N2O accumulation and emission.

Metabolic profiling suggests two sources of organic matter shape microbial activity, but not community composition, in New Zealand fjords

Depth and location influence prokaryotic and eukaryotic microbial community structure in New Zealand fjords

The paper examines microbial community structure changes in New Zealand fjords, finding depth and location influence prokaryotic and eukaryotic communities.

Alternative hydrogen uptake pathways suppress methane production in ruminants

This study identifies alternative hydrogen uptake pathways in ruminants that reduce methane production by competing with methanogens for hydrogen.

Novel autotrophic organisms contribute significantly to the internal carbon cycling potential of a boreal lake

The paper shows that autotrophic carbon fixation and internal carbon cycling are significant in a boreal lake, even below the euphotic zone, driven by chemolithotrophic organisms.

Conditionally rare taxa contribute but do not account for prokaryotic community changes in soils

The paper examines the role of conditionally rare taxa in soil microbial communities across different agricultural practices and seasons, finding they do not drive overall community changes but are influenced by spatiotemporal factors.

Response to nitrogen addition reveals metabolic and ecological strategies of soil bacteria

The paper investigates how nitrogen addition affects soil bacteria by linking changes in community structure to specific metabolic strategies.

Soil classification predicts differences in prokaryotic communities across a range of geographically distant soils once pH is accounted for

The paper shows that soil classification explains microbial community differences beyond pH and land use in New Zealand soils.

Are oceanic fronts ecotones? Seasonal changes along the Subtropical Front show fronts as bacterioplankton transition zones but not diversity hotspots

The paper investigates whether oceanic fronts act as ecotones by analyzing seasonal changes in bacterioplankton communities along the Subtropical Front, finding they are transition zones but not diversity hotspots.
