Response of N2O production rate to ocean acidification in the western North Pacific

Ocean acidification, induced by the increase in anthropogenic CO2 emissions, has a profound impact on marine organisms and biogeochemical processes1. The response of marine microbial activities to ocean acidification might play a crucial role in the future ...

Comparison of two carbon-nitrogen regulatory models calibrated with mesocosm data

Shubham Krishna

Marine phytoplankton can regulate their stoichiometric composition in response to variations in the availability of nutrients, light and the pH of seawater. Varying elemental composition of photoautotrophs affects several important ecological and biogeoche ...

Vibrio cholerae filamentation promotes chitin surface attachment at the expense of competition in biofilms

Alexandre Louis André Persat

Collective behavior in spatially structured groups, or biofilms, is the norm among microbes in their natural environments. Though biofilm formation has been studied for decades, tracing the mechanistic and ecological links between individual cell morpholog ...

Effects of Sphagnum Leachate on Competitive Sphagnum Microbiome Depend on Species and Time

Alexandre Buttler, Luca Bragazza, Constant Signarbieux, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Samuel Thomas Gabriel Hamard

Plant specialized metabolites play an important role in soil carbon (C) and nutrient fluxes. Through anti-microbial effects, they can modulate microbial assemblages and associated microbial-driven processes, such as nutrient cycling, so to positively or ne ...

Dispersal limitations and historical factors determine the biogeography of specialized terrestrial protists

Enrique Lara, Edward Mitchell, Bertrand Fournier, Luca Bragazza, Mariusz Lamentowicz

Recent studies show that soil eukaryotic diversity is immense and dominated by micro-organisms. However, it is unclear to what extent the processes that shape the distribution of diversity in plants and animals also apply to micro-organisms. Major diversif ...

Light availability impacts structure and function of phototrophic stream biofilms across domains and trophic levels

Tom Ian Battin

Phototrophic biofilms are ubiquitous in freshwater and marine environments where they are critical for biogeochemical cycling, food webs and in industrial applications. In streams, phototrophic biofilms dominate benthic microbial life and harbour an immens ...

Assimilation, translocation, and utilization of carbon between photosynthetic symbiotic dinoflagellates and their planktic foraminifera host

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Some species of planktic foraminifera inhabiting oligotrophic surface water environments are in an obligate symbiotic relationship with dinoflagellate microalgae, which can assimilate carbon (C) through photosynthesis. However, the mechanism and dynamics o ...

Surviving anoxia in marine sediments: The metabolic response of ubiquitous benthic foraminifera (Ammonia tepida)

Anders Meibom, Stéphane Laurent Escrig, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

High input of organic carbon and/or slowly renewing bottom waters frequently create periods with low dissolved oxygen concentrations on continental shelves and in coastal areas; such events can have strong impacts on benthic ecosystems. Among the meiofauna ...
