Food web structure and energy flux dynamics, but not taxonomic richness, influence microbial ecosystem functions in a Sphagnum-dominated peatland
Alexandre Buttler, Edward Mitchell, Vincent Eric Jules Jassey
Soil microbial communities are vital for multiple ecosystem processes and services. In particular, soil microbial food webs are key determinants of soil biodiversity, functioning and stability. Unclear, however, is how struc-tural features of food webs, su ...
ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER2023New and improved methods for integrated models of metabolism and gene expression
The beginning of the 21st century was marked by the advent of disruptive technologies, which ushered an era of groundbreaking advances in fundamental sciences, carried by the great pace at which computational capabilities spread and evolved. But the new ce ...
EPFL2021Viral Transfer and Inactivation through Zooplankton Trophic Interactions
Tamar Kohn, Virginie Bachmann, Xavier Fernandez Cassi, Margot Ninon Lauren Olive
Waterborne viruses are responsible for numerous diseases and are abundant in aquatic systems. Understanding the fate of viruses in natural systems has important implications for human health. This research quantifies the uptake of bacteriophage T4 and the ...
2020Thinking like a consumer: Linking aquatic basal metabolism and consumer dynamics
Tom Ian Battin, Marta Boix Canadell, Janine Rüegg
The increasing availability of high‐frequency freshwater ecosystem metabolism data provides an opportunity to identify links between metabolic regimes, as gross primary production and ecosystem respiration patterns, and consumer energetics with the potenti ...
2020Methylation of arsenic by single-species and soil-derived microbial cultures
Arsenic (As) is simultaneously a ubiquitous and a toxic element. Arsenic is subject to bio-transformations catalyzed by microorganisms constituting the As biogeochemical cycle. The primordial Earth was devoid of oxygen, exposing life to the highly mobile a ...
EPFL2020Effects of Sphagnum Leachate on Competitive Sphagnum Microbiome Depend on Species and Time
Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Constant Signarbieux, 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 ...
2019A fish intestinal barrier model to assess the interaction with chemicals in vitro
The intestinal epithelium acts as vital gate keeper between the fish and its surrounding environment. A single layer of connected epithelial cells forms a selective barrier, which, among other essential functions, is important for nutrient uptake and defen ...
EPFL2019Ecological implications of gene regulation by TfoX and TfoY among diverse Vibrio species
Melanie Blokesch, Candice Stoudmann, Noémie Matthey, Lisa Christina Metzger, Esther Jeanne Collas
Bacteria of the genus Vibrio are common members of aquatic environments where they compete with other prokaryotes and defend themselves against grazing predators. A macromolecular protein complex called the type VI secretion system (T6SS) is used for both ...
2019An ecotoxicological view on neurotoxicity assessment
The numbers of potential neurotoxicants in the environment are raising and pose a great risk for humans and the environment. Currently neurotoxicity assessment is mostly performed to predict and prevent harm to human populations. Despite all the efforts in ...
SPRINGEROPEN2018Light availability impacts structure and function of phototrophic stream biofilms across domains and trophic levels
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 ...
