Effects of hydropeaking waves offsets on growth performances of juvenile Salix species

Alexandre Buttler, Paolo Perona, Pascal Turberg, Constant Signarbieux, Lorenzo Gorla

Hydropower production and other human activities change the natural flow regime of rivers (e.g., hydropeaking effects), in turn, impacting the riparian environment. Here we present an experiment conceived to investigate the response of forced offsets in wa ...

An unexpected role for mixotrophs in the response of peatland carbon cycling to climate warming

Alexandre Buttler, Edward Mitchell, Luca Bragazza, Vincent Eric Jules Jassey, Constant Signarbieux, Bjorn Jozef Maria Robroek, Enrique Lara, Robert Thomas Edmund Mills, Bertrand Fournier

Mixotrophic protists are increasingly recognized for their significant contribution to carbon (C) cycling. As phototrophs they contribute to photosynthetic C fixation, whilst as predators of decomposers, they indirectly influence organic matter decompositi ...

Modeling of Hydrological Processes in Arid Agricultural Regions

David Andrew Barry

Understanding of hydrological processes, including consideration of interactions between vegetation growth and water transfer in the root zone, underpins efficient use of water resources in arid-zone agriculture. Water transfers take place in the soil-plan ...

Experimental warming differentially affects microbial structure and activity in two contrasted moisture sites in a Sphagnum-dominated peatland

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey

Several studies on the impact of climate warming have indicated that peat decomposition/mineralization will be enhanced. Most of these studies deal with the impact of experimental warming during summer when prevalent abiotic conditions are favorable to dec ...

Evolution of brown carbon in wildfire plumes

Athanasios Nenes, Junqiu Liu

Particulate brown carbon (BrC) in the atmosphere absorbs light at subvisible wavelengths and has poorly constrained but potentially large climate forcing impacts. BrC from biomass burning has virtually unknown lifecycle and atmospheric stability. Here, BrC ...

Worldwide impacts of climate change on energy for heating and cooling

Marc Vielle, Frédéric Louis François Babonneau, Santosh Ram Joshi

The energy sector is not only a major contributor to greenhouse gases, it is also vulnerable to climate change and will have to adapt to future climate conditions. The objective of this study is to analyze the impacts of changes in future temperatures on t ...

Thermodynamics in the hydrologic response: Travel time formulation and application to Alpine catchments

Andrea Rinaldo, Michael Lehning, Bettina Schaefli, Francesco Comola

This paper presents a spatially-explicit model for hydro-thermal response simulations of Alpine catchments, accounting for advective and non-advective energy fluxes in stream networks characterized by arbitrary degrees of geomorphological complexity. The r ...

The effect of warmer or cooler winters on European beech phenology carries over the phenophases of next growing season

Constant Signarbieux

Phenology of trees of temperate regions has become an important research topic for global change issues over the last two decades because of its major role in regulating ecosystems processes such as carbon cycle and species interactions. While spring pheno ...

Changes in dissolved iron deposition to the oceans driven by human activity: a 3-D global modelling study

Athanasios Nenes

The global atmospheric iron (Fe) cycle is parameterized in the global 3-D chemical transport model TM4-ECPL to simulate the proton- and the organic ligand-promoted mineral-Fe dissolution as well as the aqueous-phase photochemical reactions between the oxid ...

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 ...
