Composition and superposition of alluvial deposits drive macro-biological soil engineering and organic matter dynamics in floodplains

Claire Guenat, Pascal Turberg, Rodolphe Schlaepfer, Renée-Claire Le Bayon, Andreas Cedric Schomburg

Soil structure formation in alluvial soils is a fundamental process in near-natural floodplains. A stable soil structure is essential for many ecosystem services and helps to prevent river bank erosion. Plants and earthworms are successful soil engineering ...

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 ...

Partitioning of uranyl between ferrihydrite and humic substances at acidic and circum-neutral pH

Gabrielle Dublet

As part of a larger study of the reactivity and mobility of uranyl (U(VI) O-2(2+)) cations in subsurface environments containing natural organic matter (NOM) and hydrous ferric oxides, we have examined the effect of reference humic and fulvic substances on ...

Subordinate plant species moderate drought effects on earthworm communities in grasslands

Alexandre Buttler, Claire Guenat, Pierre Rémi Mariotte, Renée-Claire Le Bayon

Loss of plant diversity resulting from forecasted drought events is likely to alter soil functioning and affect earthworm communities. Plant-soil interactions are expected to play an important role in mediating climate change effects on soil decomposers. I ...

Responses of soil properties and crop yields to different inorganic and organic amendments in a Swiss conventional farming system

Konstantin Svetlozarov Gavazov, Luca Bragazza, Guillaume Blanchet

In agro-ecosystems, fertilization practices are crucial for sustaining crop productivity. Here, based on a 50-year long-term experiment, we studied the influence of fertilization practices (inorganic and/or organic) and nitrogen (N) application rates on (i ...

On-chip microfluidic biocommunication assay for studying male-induced demise in C. elegans hermaphrodites

Martinus Gijs, Thomas Lehnert, Matteo Cornaglia, Li Dong

Like other animals, C. elegans nematodes have the ability to socially interact and to communicate through exchange and sensing of small soluble signaling compounds that help them cope with complex environmental conditions. For the time being, worm biocommu ...

NanoSIMS analysis of organic carbon from the Tissint Martian meteorite: Evidence for the past existence of subsurface organic-bearing fluids on Mars

Philippe Gillet, Jing Yang, Lin Xu

Two petrographic settings of carbonaceous components, mainly filling open fractures and occasionally enclosed in shock-melt veins, were found in the recently fallen Tissint Martian meteorite. The presence in shock-melt veins and the deuterium enrichments ( ...

Issues involved with thermoactive geotechnical systems: characterization of thermomechanical soil behavior and soil-structure interface behaviour

Lyesse Laloui, Melis Sütman

This paper focuses on the main issues discussed during a session on the impact of thermohydromechanical behavior of soils on thermoactive geotechnical systems, and how they could affect the performance of thermoactive geotechnical systems. Both soil behavi ...

Patterns of earthworm communities and species traits in relation to the perturbation gradient of a restored floodplain

Edward Mitchell, Renée-Claire Le Bayon, Bertrand Fournier

Little is known about the diversity and ecology of earthworms in flocdplains, as well as their response to natural and anthropic perturbations (e.g. floods, river channelisation, floodplain restoration). We characterised the patterns of earthworm communiti ...

Earthworm communities in alluvial forests: Influence of altitude, vegetation stages and soil parameters

Claire Guenat, Géraldine Michèle Bullinger, Jean-Michel Gobat, Renée-Claire Le Bayon

In many terrestrial ecosystems, soil parameters usually regulate the distribution of earthworm communities.In alluvial ecosystems, few studies have investigated the impact of periodic floods and alluvium deposition on soil fauna. In this context, we assume ...
