Open AccessEnzyme adaptation to habitat thermal legacy shapes the thermal plasticity of marine microbiomes
Microbial communities respond to temperature with physiological adaptation and compositional turnover. Whether thermal selection of enzymes explains marine microbiome plasticity in response to temperature rema...

Open AccessGenomic and metabolic adaptations of biofilms to ecological windows of opportunity in glacier-fed streams
In glacier-fed streams, ecological windows of opportunity allow complex microbial biofilms to develop and transiently form the basis of the food web, thereby controlling key ecosystem processes. Using metageno...

Open AccessDiscovery of Afifi, the shallowest and southernmost brine pool reported in the Red Sea
The previously uncharted Afifi brine pool was discovered in the eastern shelf of the southern Red Sea. It is the shallowest brine basin yet reported in the Red Sea (depth range: 353.0 to 400.5 m). It presents ...

Open AccessThe role of fungi in heterogeneous sediment microbial networks
While prokaryote community diversity and function have been extensively studied in soils and sediments, the functional role of fungi, despite their huge diversity, is widely unexplored. Several studies have, n...

Open AccessPublisher Correction: Dispersal homogenizes communities via immigration even at low rates in a simplified synthetic bacterial metacommunity
In the original version of this article, the green and blue outlines in Figure 2b, top centre and right panels were inadvertently shifted left from the correct position. This has now been corrected in the PDF ...

Open AccessDispersal homogenizes communities via immigration even at low rates in a simplified synthetic bacterial metacommunity
Selection and dispersal are ecological processes that have contrasting roles in the assembly of communities. Variable selection diversifies and strong dispersal homogenizes them. However, we do not know whethe...

Open AccessConsistent bacterial selection by date palm root system across heterogeneous desert oasis agroecosystems
Highly productive conventional agroecosystems are spatially embedded in resource-homogeneous systems and count on generally nutrient-rich soils. On the contrary, desert oases are isolated, the soil is relative...

Open AccessFiddler crab bioturbation determines consistent changes in bacterial communities across contrasting environmental conditions
Ecosystem functions are regulated by compositional and functional traits of bacterial communities, shaped by stochastic and deterministic processes. Biogeographical studies have revealed microbial community ta...

Open AccessMeasuring the role of seagrasses in regulating sediment surface elevation
Seagrass meadows provide numerous ecosystem services and their rapid global loss may reduce human welfare as well as ecological integrity. In common with the other ‘blue carbon’ habitats (mangroves and tidal m...

Open AccessAn impaired metabolic response to hydrostatic pressure explains Alcanivorax borkumensis recorded distribution in the deep marine water column
Alcanivorax borkumensis is an ubiquitous model organism for hydrocarbonoclastic bacteria, which dominates polluted surface waters. Its negligible presence in oil-contaminated deep waters (as observed during the D...

Open AccessMicrobial oil-degradation under mild hydrostatic pressure (10 MPa): which pathways are impacted in piezosensitive hydrocarbonoclastic bacteria?
Oil spills represent an overwhelming carbon input to the marine environment that immediately impacts the sea surface ecosystem. Microbial communities degrading the oil fraction that eventually sinks to the sea...

Open AccessThe trade-off between heat tolerance and metabolic cost drives the bimodal life strategy at the air-water interface
The principle of oxygen and capacity limitation of thermal tolerance in ectotherms suggests that the long-term upper limits of an organism's thermal niche are equivalent to the upper limits of the organism's f...

Open AccessPlant-mediated interspecific horizontal transmission of an intracellular symbiont in insects
Intracellular reproductive manipulators, such as Candidatus Cardinium and Wolbachia are vertically transmitted to progeny but rarely show co-speciation with the host. In sap-feeding insects, plant tissues have be...

Open AccessBacterial population and biodegradation potential in chronically crude oil-contaminated marine sediments are strongly linked to temperature
Two of the largest crude oil-polluted areas in the world are the semi-enclosed Mediterranean and Red Seas, but the effect of chronic pollution remains incompletely understood on a large scale. We compared the ...

Open AccessDifferent pioneer plant species select specific rhizosphere bacterial communities in a high mountain environment
The rhizobacterial communities of 29 pioneer plants belonging to 12 species were investigated in an alpine ecosystem to assess if plants from different species could select for specific rhizobacterial communit...

Article
Environmental conditions and community evenness determine the outcome of biological invasion
Biological invasion is widely studied, however, conclusions on the outcome of this process mainly originate from observations in systems that leave a large number of experimental variables uncontrolled. Here u...

Initial community evenness favours functionality under selective stress
It has been established that ecosystem functioning is affected by species richness, but the effect of inequalities in the relative abundances of these species — species unevenness — is less well studied. An in...

Stratified prokaryote network in the oxic–anoxic transition of a deep-sea halocline
Beneath the eastern Mediterranean Sea lies one of the most extreme environments on Earth capable of sustaining life. Here the seawater floats on a lake of anoxic hypersaline brine known as the Bannock basin, a...
