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 ...

Coupling X-ray computed tomography and freeze-coring for the analysis of fine-grained low-cohesive soils

Claire Guenat, Pascal Turberg, Adrien Francis Olivier Liernur, Andreas Cedric Schomburg, Renée-Claire Le Bayon

This paper presents the coupling of freeze-core sampling with X-ray CT scanning for the analysis of the soil structure of fine-grained, low-cohesive soils. We used a medical scanner to image the 3D soil structure of the frozen soil cores, providing X-ray C ...

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 ...

Land use and soil texture effects on organic carbon change in dryland soils, Senegal

Claire Guenat, Assize Touré

Soil organic carbon (SOC) losses due to poor soil management in dryland are now well documented. However, the in- fluence of soil properties on organic carbon change is not well known. The groundnut plant (Arachis hypogaea L.), and the dominant crop system ...

Spatio-temporal heterogeneity of riparian soil morphology in a restored floodplain

Claire Guenat, Géraldine Michèle Bullinger, Edward Mitchell, Bertrand Fournier

Floodplains have been intensively altered in industrialized countries, but are now increasingly being restored. It is therefore important to assess the effect of these restoration projects on the aquatic and terrestrial components of ecosystems. However, d ...
