Chronic warming and dry soils limit carbon uptake and growth despite a longer growing season in beech and oak

Charlotte Grossiord, Yann Vitasse, Margaux Clara Lou Didion-Gency

Progressively warmer and drier climatic conditions impact tree phenology and carbon cycling with large consequences for forest carbon balance. However, it remains unclear how individual impacts of warming and drier soils differ from their combined effects ...

Partitioning soil organic carbon into its centennially stable and active fractions with machine-learning models based on Rock-Eval (R) thermal analysis (PARTY(SOC)v2.0 and PARTY(SOC)v2.0 (EU))

Juan Carlos Quezada Rivera

Partitioning soil organic carbon (SOC) into two kinetically different fractions that are stable or active on a century scale is key for an improved monitoring of soil health and for more accurate models of the carbon cycle. However, all existing SOC fracti ...

A coupled hydro – mechanical approach for modelling the volume change behaviour of compacted bentonite

Lyesse Laloui, Alessio Ferrari, Jose Antonio Bosch Llufriu

The volumetric response of compacted bentonites against environmental actions is a key aspect in most designs of nuclear waste repositories. The safety assessment of such repositories must account for robust and reliable models of stress–strain for bentoni ...

Exploring the Sources of Unexpected High Methane Concentrations and Fluxes From Alpine Headwater Streams

Amber Joy Ulseth, Sabine Flury McGinnis

The dynamics of methane generation and evasion from well-oxygenated, oligotrophic streams have been traditionally neglected. We estimated evasion of methane and assessed its sources and production pathways using a stable isotope approach in 16 oxygen-rich ...

The influence of different hydro-mechanical paths on final properties of saturated MX80 bentonite samples

Lyesse Laloui, Alessio Ferrari, Patrycja Ewelina Baryla

Compacted bentonite is considered to be used for deep geological nuclear waste disposal due to its isolation properties such as low permeability, solute retention and swelling pressure. To ensure that these properties will remain favourable throughout the ...

Effects of flooding on phosphorus and iron mobilization in highly weathered soils under different land-use types: Short-term effects and mechanisms

Thomas Guillaume

The strong affinity of phosphorus (P) to iron (Fe) oxides and hydroxides in highly weathered tropical soils limits P availability and therefore plant productivity in tropics. In flooded soils, however, P fixed by Fe oxides and hydroxides can be released in ...

Impacts of regional climatic fluctuations on radial growth of Siberian and Scots pine at Mukhrino mire (central-western Siberia)

Luca Bragazza, Guillaume Blanchet, Baptiste Calliari

Ring width (TRW) chronologies from Siberian (Pinus sibirica) and Scots (Pinus sylvestris) pine trees were sampled at Mukhrino - a large mire complex in central-western Siberia - to evaluate the impacts of hydroclimatic variability on tree growth over the l ...

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 ...

Use of environmental tracing to constrain a rainfall-runoff model. Application to the Haute-Mentue catchment

André Musy

Presented study is aimed at using additional information to improve process representativity of hydrological modelling. The study region is the Haute-Mentue catchment located in the western part of Switzerland, 20 km north of Lausanne. Previous research in ...
