Scour depth under pipelines placed on weakly cohesive soils

We here study the scouring processes that evolve around a submarine pipeline placed on a weakly cohesive seabed. We first analyze some laboratory tests carried out by Vijaya Kumar et al. [21], Xu et al. [25] and Zhou et al. [28] that focused on the scourin ...

Collapse-upon-wetting behaviour of a volcanic soil

Alessio Ferrari, Eleonora Crisci

Experimental results of volumetric response of a volcanic soil were collected in standard oedometric tests, with the aim to evaluate the volumetric response of this soil when subjected to loading and wetting paths. Microstructural features of reconstituted ...

Sustained impact of drought on wet shrublands mediated by soil physical changes

Robert Thomas Edmund Mills

Projected climate warming may substantially increase carbon emissions from wet organic soils, contributing to a positive feedback between the terrestrial carbon cycle and climate change. Evidence suggests that in these soils the stimulation of soil respira ...

Subordinate plants mitigate drought effects on soil ecosystem processes by stimulating fungi

Alexandre Buttler, Pierre Rémi Mariotte, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek

The subordinate insurance hypothesis suggests that highly diverse communities contain greater numbers of subordinate species than less diverse communities. It has previously been reported that subordinate species can improve grassland productivity durin ...

Linking soil microbial communities to vascular plant abundance along a climate gradient

Alexandre Buttler, Edward Mitchell, Luca Bragazza, Richard David Bardgett

The ongoing expansion of shrub cover in response to climate change represents a unique opportunity to explore the link between soil microbial communities and vegetation changes. This link is particularly important in peatlands where shrub expansion is expe ...

Modeling Soil–Plant Dynamics: Assessing Simulation Accuracy by Comparison with Spatially Distributed Crop Yield Measurements

Sara Bonetti

Coupling hydrological models with plant physiology is crucial to capture the feedback mechanisms occurring within the soil–plant–atmosphere continuum. However, the ability of such models to describe the spatial variability of plant responses to different e ...

Evaluation of mulching in drip irrigated areas in semi-arid regions (Burkina Faso) and related hydrogeological context

Info4Dourou2.0 is a research project aiming at improving agricultural yield and water consumption in drip irrigated areas in semi-arid regions by using continuous soil humidity measurements. Within this framework, the main goal of this thesis was to invest ...

Storage and release of organic carbon from glaciers and ice sheets

Tom Ian Battin

Polar ice sheets and mountain glaciers, which cover roughly 11% of the Earth's land surface, store organic carbon from local and distant sources and then release it to downstream environments. Climate-driven changes to glacier runoff are expected to be lar ...

Carbon storage versus albedo change: radiative forcing of forest expansion in temperate mountainous regions of Switzerland

Michael Lehning, Marc Schneebeli Zeugin, Mathias Thierry Pierre Bavay

In this study, we assess the climate mitigation potential from afforestation in a mountainous snow-rich region (Switzerland) with strongly varying environmental conditions. Using radiative forcing calculations, we quantify both the carbon sequestration pot ...

Hydrological dynamics and fire history of the last 1300 years in western Siberia reconstructed from a high-resolution, ombrotrophic peat archive

Alexandre Buttler, Vincent Eric Jules Jassey, Mariusz Lamentowicz

Siberian peatlands provide records of past changes in the continental climate of Eurasia. We analyzed a core from Mukhrino mire in western Siberia to reconstruct environmental change in this region over the last 1300 years. The pollen analysis revealed lit ...
