Metabolic interactions underpinning high methane fluxes across terrestrial freshwater wetlands

The paper integrates multi-omics data from wetlands to link microbial communities to methane fluxes, identifying conserved genera and metabolic interactions that influence emissions.

Sulfur oxidation and reduction are coupled to nitrogen fixation in the roots of a salt marsh foundation plant species

This study shows sulfur oxidation and reduction are coupled to nitrogen fixation in the roots of Spartina alterniflora, with a novel symbiosis involving Candidatus Thiodiazotropha.

Restoration and resilience to sea level rise of a salt marsh affected by dieback events in Charleston, SC

This study shows that salt marshes in Charleston, SC, have not fully recovered 10 years after dieback events, highlighting the need for restoration and climate change mitigation.

The core root microbiome of Spartina alterniflora is predominated by sulfur-oxidizing and sulfate-reducing bacteria in Georgia salt marshes, USA

This study examines the root microbiome of Spartina alterniflora in Georgia salt marshes, finding sulfur-oxidizing and sulfate-reducing bacteria dominate and are linked to plant productivity.

Minnesota peat viromes reveal terrestrial and aquatic niche partitioning for local and global viral populations

The paper analyzes viromes from a boreal peatland to reveal niche partitioning of viruses between terrestrial and aquatic environments, showing distinct viral community patterns.

Genomic characterization and computational phenotyping of nitrogen-fixing bacteria isolated from Colombian sugarcane fields

The paper develops a computational phenotyping approach to prioritize nitrogen-fixing bacteria from sugarcane fields as biofertilizers based on genomic data and experimental validation.

Defining the seafloor microbiome of the Gulf of Mexico and its response to oil perturbation

The paper characterizes the seafloor microbiome in the Gulf of Mexico, showing it is consistent with depth and sediment stratification, and that DWH-impacted sites had recovered after two years.

Diversity of active viral infections within the Sphagnum microbiome

The paper uses metatranscriptomics to identify active viral infections in the Sphagnum microbiome, revealing diverse viral taxa and potential virus-host interactions.

Experimental warming reduces the diversity and functional potential of the Sphagnum microbiome

This study shows experimental warming reduces microbial diversity and functional potential in Sphagnum microbiomes, with diazotroph communities dominated by Nostocaceae under elevated temperatures.

Molybdenum-based diazotrophy in a Sphagnum peatland in northern Minnesota

This study identifies Alphaproteobacteria as the primary diazotrophs in a Sphagnum peatland, dominated by Mo-based nitrogenase, with activity influenced by light, O2, and CO2.
