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

Claire Guenat, Rodolphe Schlaepfer, Pascal Turberg, 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, Muhammad Riaz, Andreas Cedric Schomburg

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

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

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

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 ...

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

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

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 ...

Impact of flood deposits on earthworm communities in alder forests from a subalpine floodplain (Kandersteg, Switzerland)

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

In many ecosystems, bioindication is a tool to estimate biodiversity and quality of environment. In soils,invertebrates are generally suitable bioindicators, especially earthworms. In floodplains, young alluvial soils are exposed to sedimentation and erosi ...
