Spatially Explicit Linkages Between Redox Potential Cycles and Soil Moisture Fluctuations

Andrea Rinaldo, Rizlan Bernier-Latmani, Paolo Benettin, Manon Frutschi, Simiao Wang, Filippo Miele, Mitra Asadollahi

Reduction-oxidation cycles measured through soil redox potential (Eh) are associated with dynamic soil microbial activity. Understanding changes in the composition of, and resource use by, soil microbial communities requires Eh predictability under shiftin ...

Heat stress reduces the contribution of diazotrophs to coral holobiont nitrogen cycling

Anders Meibom, Nils Rädecker, Claudia Isabella Pogoreutz, Gabriela Hannah Holligan Perna

Efficient nutrient cycling in the coral-algal symbiosis requires constant but limited nitrogen availability. Coral-associated diazotrophs, i.e., prokaryotes capable of fixing dinitrogen, may thus support productivity in a stable coral-algal symbiosis but c ...

Pioneer plant Phalaris arundinacea and earthworms promote initial soil structure formation despite strong alluvial dynamics in a semi-controlled field experiment

Claire Guenat, Pascal Turberg, Renée-Claire Le Bayon, Andreas Cedric Schomburg, Muhammad Riaz

Soil structure formation is among the most important processes in riverfloodplains which are strongly influ-enced by alluvial dynamics. In the context of river restoration projects, a better understanding of soil structureformation in habitats adjacent to ...

Short-term effects of biochar on grapevine fine root dynamics and arbuscular mycorrhizae production

Application of biochar to the soil is globally recognised as a means to improve soil structure and fertility, increase carbon sequestration, enhance crop production and mitigate climate change. However, although the fine root system is fundamental for plan ...

Microbial dynamics in petroleum oilfields and their relationship with physiological properties of petroleum oil reservoirs

Edgard Gnansounou

Petroleum is produced by thermal decay of buried organic material over millions of years. Petroleum oilfield ecosystems represent resource of reduced carbon which favours microbial growth. Therefore, it is obvious that many microorganisms have adapted to h ...

Associative interplay of plant growth promoting rhizobacteria (Pseudomonas aeruginosa QS40) with nitrogen fertilizers improves sunflower (Helianthus annuus L.) productivity and fertility of aridisol

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Muhammad Saleem Arif, Muhammad Riaz

The environmental and economic impacts of chemical fertilizer have encouraged farmers to integrate them with organic materials, an important nutrient management strategy for sustainable agriculture production. In the present study, we conducted field exper ...

Are flood-driven turbidity currents hot spots for priming effect in lakes?

Damien Bouffard

In deep stratified lakes, such as Lake Geneva, flood-driven turbidity currents are thought to contribute to the replenishment of deep oxygen by significant transport of river waters saturated with oxygen into the hypolimnion. The overarching aim of this st ...

Soil microbial community resistance to drought and links to C stabilization in an Australian grassland

Pierre Rémi Mariotte

Drought is predicted to increase in many areas of the world, which can greatly influence soil microbial community structure and C stabilization. Increasing soil carbon (C) stabilization is an important strategy to mitigate climate change effects, but the u ...

Effects of endogeic earthworms on the soil organic matter dynamics and the soil structure in urban and alluvial soil materials

Pascal Turberg, Jean-Michel Gobat, Renée-Claire Le Bayon

Earthworms are considered as key actors of soil processes at different spatial and temporal scales and provide essential ecosystem services linked to climate regulation or primary production. However, little is known about their basic functional roles (e.g ...

Diminished soil functions occur under simulated climate change in a sup-alpine pasture, but heterotrophic temperature sensitivity indicates microbial resilience

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Thomas Spiegelberger, Robert Thomas Edmund Mills

The pressure of climate change is disproportionately high in mountainous regions, and small changes may push ecosystem processes beyond sensitivity thresholds, creating new dynamics of carbon and nutrient cycling. Given that the rate of organic matter deco ...
