Fungi and viruses as important players in microbial mats
Fungi and viruses are important players of microbial mats, potentially shaping element cycling, food web structure and function.
Auxotrophic interactions: a stabilizing attribute of aquatic microbial communities?
Discussion of the potential impact of auxotrophy, the requirement by an organism for an organic micronutrient, on the stability of aquatic microbial communities in the face of environmental changes.

Temporal dynamics in the taxonomic and functional profile of the Sphagnum-associated fungi (mycobiomes) in a Sphagnum farming field site in Northwestern Germany
Bacterial microbiota associated with insect vectors of grapevine Bois noir disease in relation to phytoplasma infection
This study describes the microbial community associated with insect vectors of Bois noir disease of grapevine in relation to presence/absence of its etiological agent, ‘Candidatus Phytoplasma solani’.
A converging subset of soil bacterial taxa is permissive to the IncP-1 plasmid pKJK5 across a range of soil copper contamination
Long term Cu contamination alters soil bacterial community structure, but has little effect on the effective recipient pool for an exogenously introduced IncP plasmid.
Redox stratification within cryoconite granules influences the nitrogen cycle on glaciers
Development of layered microbial structure and resulting redox stratification influence the nitrogen cycling within cryoconite granules, naturally occurring microbial structures found in glacier environments.
Stochastic processes dominate marine free-living Vibrio community assembly in a subtropical gulf
High-throughput amplicon sequencing of the Vibrio-specific 16S rRNA gene reveals for the first time that stochastic processes dominate marine free-living Vibrio community assembly in a subtropical gulf.
Shifts in the protist community associated with an anticyclonic gyre in the Alboran Sea (Mediterranean Sea)
Genetic analysis of natural samples reveals that the interactions among different fractions of the plankton (phototrophs, heterotrophs and non-free living forms) determine the community response to environmental changes.
Supplemental selenium source on gut health: insights on fecal microbiome and fermentation products of growing puppies
Supplementation of dog food with organic selenium over inorganic selenium positively modulated the gut microbiome of growing puppies which might contribute to gut health.
Breeding selection imposed a differential selective pressure on the wheat root-associated microbiome
Wheat root-associated microbiomes have dramatically changed through a transect of breeding history, and ancient wheat accessions pose a stronger selection pressure on microorganisms.
Covariation patterns of phytoplankton and bacterioplankton in hypertrophic shallow lakes
Soil P reduces mycorrhizal colonization while favors fungal pathogens: observational and experimental evidence in Bipinnula (Orchidaceae)
In situ P addition reduces mycorrhizal colonization in Bipinnula fimbriata in the short term, and this is coupled with an increase in pathogen richness.
Long-term nitrogen addition in maize monocultures reduces in vitro inhibition of actinomycete standards by soil-borne actinomycetes
Actinomycete bacteria from soils fertilized with nitrogen for 57 years were less likely than actinomycetes from long-term non-fertilized soils to produce antibiotics that inhibited the growth of other actinomycetes.
Comparative analyses of saprotrophy in Salisapilia sapeloensis and diverse plant pathogenic oomycetes reveal lifestyle-specific gene expression
Comparative analyses between the saprotrophic oomycete Salisapilia sapeloensis and its pathogenic relatives indicate that distinct gene expression patterns underpin the different lifestyles in oomycetes.
Microbiomes in a manganese oxide producing ecosystem in the Ytterby mine, Sweden: impact on metal mobility
Defining the spatial distribution of microorganisms and elements in this REE-enriched Mn-oxide producing ecosystem contribute to a better understanding of specific niches and parameters driving the emergence of these communities.
The ‘fertile island effect’ of Welwitschia plants on soil microbiota is influenced by plant gender
The ‘fertile island effect’ on soil microbiota of desert gymnosperm Welwitschia mirabilis in the Namib Desert is influenced by plant gender.
Community composition of arctic root-associated fungi mirrors host plant phylogeny
Microbial adaptation in vertical soil profiles contaminated by an antimony smelting plant
Results indicated that microbial adaptation changed in response to different levels of contamination throughout the soil profiles, which were distinct from the control profile.
Acid-adapted microalgae exhibit phenotypic changes for their survival in acid mine drainage samples
This study investigated the morphological, physiological and metabolomic changes in acid-adapted microalgal strains that help them survive in acid mine drainage samples.
Soil microbial succession following surface mining is governed primarily by deterministic factors
Soil microbial communities were influenced more by environmental factors than by time following surface mining disturbance.
Mild hydrostatic-pressure (15 MPa) affects the assembly, but not the growth, of oil-degrading coastal microbial communities tested under limiting conditions (5°C, no added nutrients)
Mild hydrostatic pressure (15 MPa, equal to about 1500 meter below sea surface level) can shape the composition of oil-degrading communities even in environmental conditions preventing intense growth, such as cold oligotrophic environments.
Rotifers weaken the efficiency of the cyanobacterium defence against ciliate grazers
The presence of rotifers able to feed on cyanobacterial mucilage led to decreased effectiveness of inducible defence in two ways, by increasing dispersion of the cyanobacterial trichomes, thus loosening cyanobacterial mats, and by ingestion of the exopolysaccharide material covering trichomes.
